Number of Ranges parameter

The number of Ranges parameter indicates in binary the number of ranges to be transmitted in the IE. It shall have a minimum value of 1.

RANGEi_LOWER

If $(impr-BA-range-handling)$ is not supported:

$begin
The RANGEi_LOWER is coded as the binary representation of the ARFCN used as the lower limit of a range of frequencies to be used by the mobile station in cell selection (see 3GPP TS 45.008 and 3GPP TS 23.022)
$end

If $(impr-BA-range-handling)$ is supported:

$begin
The RANGEi_LOWER is coded as the binary representation of the ARFCN used as the lower limit of a range of frequencies which could be used by the mobile station in cell selection (see 3GPP TS 45.008 and 3GPP TS 23.022)
$end

RANGEi_HIGHER

If $(impr-BA-range-handling)$ is not supported:

$begin
The RANGEi_HIGHER is coded as the binary representation of the ARFCN used as the higher limit of a range of frequencies to be used by the mobile station in cell selection (see 3GPP TS 45.008 and 3GPP TS 23.022)
$end

If $(impr-BA-range-handling)$ is supported:

$begin
The RANGEi HIGHER is coded as the binary representation of the ARFCN used as the higher limit of a range of frequencies which could be used by the mobile station in cell selection (see 3GPP TS 45.008 and 3GPP TS 23.022)
$end

If the length of the BA range information element is greater than the number of octets required to carry the Number of Ranges given in octet 3, then any unused octets or parts of octets at the end of the IE shall be considered as spare.

If $(impr-BA-range-handling)$ is supported:

If a mobile station receives range information which has ranges or part of the ranges which are not supported by the mobile station, the mobile station shall take into account those parts of the ranges which it does support.

10.5.2.1b Cell Channel Description

The purpose of the Cell Channel Description information element is to provide the reference frequency list to be used to decode the mobile allocation information element.

The Cell Channel Description is a type 3 information element with 17 octets length.

There are several formats for the Cell Channel Description information element, distinguished by the "format indicator" subfield. Some formats are frequency bit maps, the others use a special encoding scheme.

NOTE: No more than 64 RF channels should be encoded in the Cell Allocation since this is the maximum number of RF channels which can be referenced in the Mobile Allocation IE.

10.5.2.1b.1 General description

Figure 10.5.2.1b.1.1 shows only a special bit numbering. The different general format is described in table 10.5.2.1b.1.1.

A GSM 900 mobile station which only supports the primary GSM band P-GSM 900 (cf. 3GPP TS 45.005) may consider all values except the value for bit map 0 as reserved.

The significance of the remaining bits depends on the FORMAT-ID. The different cases are specified in the next sub-clauses.

Mobile stations shall treat all ARFCNs in the set {0, 1, 2 … 1023} as valid ARFCN values even if the mobile station is unable to transmit or receive on that ARFCN.

10.5.2.1c BA List Pref

The purpose of the BA List Pref information element is to provide the mobile station with ARFCN information which can be used in the cell selection/reselection procedure.

The BA List Pref is a type 4 information element with a minimum length of 3 octets. No upper length limit is specified except for that given by the maximum number of octets in a L3 message (see 3GPP TS 44.006).

< RANGE LIMITS >::=

< RANGE LOWER : bit (10) >

< RANGE UPPER : bit (10) >;

The RANGE LOWER is coded as the binary representation of the ARFCN used as the lower limit of a range of frequencies to be used by the mobile station in cell selection and reselection (see 3GPP TS 45.008 and 3GPP TS 23.022).

The RANGE HIGHER is coded as the binary representation of the ARFCN used as the higher limit of a range of frequencies to be used by the mobile station in cell selection and reselection (see 3GPP TS 45.008 and 3GPP TS 23.022).

BA FREQ is coded as the binary representation of the ARFCN indicating a single frequency to be used by the mobile station in cell selection and reselection (see 3GPP TS 45.008 and 3GPP TS 23.022).

10.5.2.1d UTRAN Freq List

The UTRAN Freq List information element provides the mobile station with a list of UTRAN frequencies used by the network. These frequencies may be used in the cell selection procedure, see 3GPP TS 25.304.

FDD_ARFCN and TDD_ARFCN are defined as the UARFCN in 3GPP TS 25.101 and 3GPP TS 25.102. If both an UTRAN Freq List information element and an UTRAN Frequency List Description struct (3GPP TS 44.060) are received, the mobile station shall use the one most recently received.

The UTRAN Freq List is a type 4 information element with a minimum length of 3 octets. No upper length limit is specified except for that given by the maximum number of octets in a L3 message (see 3GPP TS 44.006).

< UTRAN Freq List >::=

< LENGTH OF UTRAN FREQ LIST : bit (8) > — length following in octets

{ 1 < FDD_ARFCN > : bit (14) } ** 0 — FDD frequencies

{ 1 < TDD_ARFCN > : bit (14) } ** 0 — TDD frequencies

<spare bit>**;

Spare bits in the end of the field are used to fill the last octet.

10.5.2.1e Cell selection indicator after release of all TCH and SDCCH IE

This IE indicates on which frequency /cell the cell selection after channel release shall be performed.

The "Cell selection indicator after release of all TCH and SDCCH" information element is coded as shown in figure 10.5.2.1e.1 and tables 10.5.2.1e.1 and 10.5.2.1e.2.

The "Cell selection indicator after release of all TCH and SDCCH" is a type 4 information element with a minimum length of 4 octets. No upper length limit is specified except for that given by the maximum number of octets in a L3 message (see 3GPP TS 44.006).

BCCH-FREQ-NCELL i, BCCH carrier of the i’th neighbour cell.

The BCCH-FREQ-NCELL i field is coded as the binary representation of the position, starting with 0, of the i’th neighbour cells BCCH carrier in the BCCH channel list. The BCCH channel list is composed of one or two BCCH channel sub lists, each sub list is derived from the set of frequencies defined by reference neighbour cell description information element or elements. In the latter case the set is the union of the two sets defined by the two neighbour cell description information elements.

In each BCCH channel sub list the absolute RF channel numbers are placed in increasing order of ARFCN, except that ARFCN 0, if included in the set, is put in the last position in the sub list. The BCCH channel list consists either of only the sub list derived from the neighbour cell description information element(s) in System Information 2/5 (and possible 2bis/5bis) or of that sub list immediately followed by the sub list derived from the neighbour cell description information element in System Information 2ter/5ter for the case System Information 2ter/5ter is also received. If the set of ARFCNs defined by the reference neighbour cell description information element or elements includes frequencies that the mobile station does not support then these ARFCNs shall be included in the list.

The notation 2/5 etc. means that the rules above apply to the neighbour cell description information elements received in System Information 2, 2bis and 2ter and to those received in System Information 5, 5bis and 5ter separately.

Range: 0 to 31/30.

Report on 3G cells:

If no more than 31 (GSM) ARFCN frequencies are included in the BA (list), the index BCCH-FREQ-NCELL 31 indicates report(s) on 3G cells.

In this case, the corresponding ‘BSIC-NCELL’ field in figure 10.5.2.20.1 carries the index of the i’th 3G neighbour cell in the 3G Neighbour Cell list defined in sub-clause 3.4.1.2.1.1, "Deriving the 3G Neighbour Cell list from the 3G Neighbour Cell Description". 3G cells with indexes above 63 are not reported (6 bits field).

If more than 31 (GSM) ARFCN frequencies are included in the BA (list), reporting of 3G cells is not possible with this IE.

Range: 0 to 63.

Report on E-UTRAN cells:

If no more than (31 – NUM_E-UTRAN_FREQUENCIES) GSM ARFCN frequencies are included in the BA (list), the BCCH-FREQ-NCELL indices from (31 – NUM_E-UTRAN_FREQUENCIES) to 30 (inclusive) indicate report(s) on E-UTRAN cells. The index BCCH-FREQ-NCELL 30 indicates a report of an E-UTRAN neighbour cell on the first frequency defined in the E-UTRAN Neighbour Cell list, the value 29 indicates a report of an E-UTRAN neighbour cell on the second frequency in the E-UTRAN Neighbour Cell list and so on.

NUM_E-UTRAN_FREQUENCIES is defined as the number of separate E-UTRAN frequencies in the E-UTRAN Neighbour Cell list.

If the BCCH-FREQ-NCELL index indicates an E-UTRAN frequency, the corresponding ‘BSIC-NCELL’ field in figure 10.5.2.20.1 contains the least significant 6 bits of the physical layer cell identity (see 3GPP TS 36.211) of the E-UTRAN neighbour cell. The corresponding ‘RXLEV-NCELL’ field in figure 10.5.2.20.1 contains the 3 bit measurement value (see 3GPP TS 45.008) in the most significant 3 bits of the field and the most significant 3 bits of the physical layer cell identity in the least significant 3 bits of the field.

If more than (31 – NUM_E-UTRAN_FREQUENCIES) GSM ARFCN frequencies are included in the BA (list), reporting of E-UTRAN cells is not possible with this IE.

BSIC-NCELL i (6 bit field)
Base station identity code of the i’th neighbour cell

For GSM cells, the BSIC-NCELL i field is coded as the binary representation of the base station identity code of the i’th neighbour cell.

Range: 0 to 63.

The MA C i bit indicates whether or not the Mobile allocation frequency list includes the i’th frequency in the cell allocation frequency list.

The cell allocation frequency list is derived from the set of frequencies defined by the reference cell channel description information element. NF denotes the number of frequencies in the cell allocation frequency list.

In the cell allocation frequency list the absolute RF channel numbers are placed in increasing order of ARFCN, except that ARFCN 0, if included in the set, is put in the last position in the list,

For a RF channel belonging to the mobile allocation the MA C i bit is coded with a "1"; i = 1, 2,…, NF.

For a RF channel not belonging to the mobile allocation the MA C i bit is coded with a "0"; i = 1, 2,…, NF.

If NF mod 8 <> 0 then bits NF to 8n in octet 3 must be coded with a "0" in each.

EXT-IND, Extension indication (octet 2, bit 6)

If received in System Information 2, 2bis, 5 or 5bis this bit indicates whether the information element carries the complete information of a BCCH channel sub list or whether a complementary information element is sent in another message.

A GSM 900 mobile station which only supports the primary GSM band P‑GSM 900 (cf. 3GPP TS 45.005) may consider this bit as a spare bit and assume that the information element carries the complete BA, see sub-clause 3.2.2.1.

NOTE 1: EXT-IND is set to 1 in the neighbour cell description information elements in System Information 2 and 2bis and 5 and 5bis respectively when more than one is needed to describe a BCCH channel sub list.

Bit 6

0 The information element carries the complete BA

1 The information element carries only a part of the BA

BA-IND, BCCH allocation sequence number indication (octet 2). Range 0 to 1

The BA-IND is needed to allow the network to discriminate measurements results related to different BAs (e.g. BA(BCCH) and BA(SACCH)) sent to the

MS.

NOTE 2: The network should change the contents of the Neighbour Cell Description information element (FORMAT-ID and/or set of ARFCNs) when changing the ciphering mode from not ciphered to ciphered with algorithm A5/1 (see sub-clause 3.4.7.2). For this purpose, the network may change the set of frequencies, by including ARFCNs not in a frequency band supported by the MS, without changing the BA-IND value, provided the position in the resulting BA(SACCH) of the ARFCNs that are candidates for measurement reporting is not altered.

The network should also ensure that different mobiles in the cell receive different sets of ARFCNs when sent encrypted with A5/

10.5.2.22a Neighbour Cell Description 2

The purpose of the Neighbour Cell Description 2 information element is to provide the absolute radio frequency channel numbers of the BCCH carriers to be monitored by the mobile stations in the cell.

RA, Random Access Information (octet 2)
This is an unformatted 8 bit field. Typically the contents of this field are coded the same as the CHANNEL REQUEST message shown in Figure 9.1.8.1 and Table 9.1.8.1, sub-clause 9.1.8. When included in an EC IMMEDIATE ASSIGNMENT TYPE 1 message (see sub-claue 9.1.59) this field is coded as the 8 least significant bits of the corresponding EC PACKET CHANNEL REQUEST message sent on the RACH (see sub-claue 9.1.65) and is never used to indicate the presence of Extended RA information. The 8 least significant bits of an EC PACKET CHANNEL REQUEST message are identified using the same method for identifying the 5 least significant of an EGPRS PACKET CHANNEL REQUEST message described in sub-clause 10.5.2.16 for the case where the Extended RA field is included in the IA Rest Octets information element (i.e. when the Request Reference IE is included in the EC IMMEDIATE ASSIGNMENT TYPE 1 message the RA field shall include all fields of the EC PACKET CHANNEL REQUEST message except for the ‘EC-NumberOfBlocks’ field).

When included in an IMMEDIATE ASSIGNMENT message sent in response to an EGPRS MULTILATERATION REQUEST message indicating ‘RLC Data Block’ method or ‘Page Response for Positioning Event’ (see sub-clause 3.5.2.1.2, sub-clause 3.11 and 3GPP TS 44.060 [76]) this field includes the 8 least significant bits of the corresponding EGPRS MULTILATERATION REQUEST message sent on the RACH (see 3GPP TS 44.060). In this case the Dedicated mode or TBF IE indicates that a Temporary Block Flow (TBF) is assigned by the IMMEDIATE ASSIGNMENT message (see sub-clause 10.5.2.25b).

When included in an IMMEDIATE ASSIGNMENT message sent in response to an EGPRS MULTILATERATION REQUEST message indicating the ‘Access Burst’ method or ‘Extended Access Burst’ method this field is ignored. In this case the Dedicated mode or TBF IE indicates that no TBF or dedicated mode resources are assigned by the IMMEDIATE ASSIGNMENT message.

T1′ (octet 3)
The T1′ field is coded as the binary representation of (FN div 1326) mod 32.

T3 (octet 3 and 4)
The T3 field is coded as the binary representation of FN mod 51. Bit 3 of octet 3 is the most significant bit and bit 6 of octet 4 is the least significant bit.

T2 (octet 4)
The T2 field is coded as the binary representation of FN mod 26.

NOTE 1: The frame number, FN modulo 42432 can be calculated as 51x((T3-T2) mod 26)+T3+51x26xT1′

10.5.2.30a Random Reference/ Establishment Cause

NCH Position on the CCCH

The values in the NCH Position field indicates the block number of the CCCH block which is used for the first NCH block and the number of blocks used for the NCH. (The block numbering corresponds to table 5 in clause 7 of 3GPP TS 45.002)

The absence of the NCH position field indicates that there is no NCH in the cell/on the carrying CCCH slot

The following coding applies if 1 or more basic physical channels are used for CCCH, not combined with SDCCHs.

The T1′ field is coded as the binary representation of (FN div 1326) mod 32.

T3 (octet 2 and 3)

The T3 field is coded as the binary representation of FN mod 51. Bit 3 of octet 2 is the most significant bit and bit 6 of octet 3 is the least significant bit.

T2 (octet 3)

The T2 field is coded as the binary representation of FN mod 26.

NOTE 1: The frame number, FN modulo 42432 can be calculated as 51x((T3-T2) mod 26)+T3+51x26xT1′

The starting time and the times mentioned above are with reference to the frame numbering in the concerned cell. They are given in units of frames (around 4.615 ms).

The Starting Time IE can encode only an interval of time of 42 432 frames, that is to say around 195.8 seconds. To remove any ambiguity, the specification for a reception at time T is that the encoded interval is (T-10808, T+31623). In rigorous terms, if we note ST the starting time:

if 0 <= (ST-T) mod 42432 <= 31623, the indicated time is the next time when FN mod 42432 is equal to ST;

if 32024 <= (ST-T) mod 42432 <= 42431, the indicated time has already elapsed.

The reception time T is not specified here precisely. To allow room for various MS implementations, the limit between the two behaviours above may be anywhere within the interval defined by:

31624 <= (ST-T) mod 42432 <= 32023.

Table 10.5.2.44.1: SI 10 Rest Octets information element

<SI10 rest octets> ::= <BA ind : bit(1)>
{ L <spare padding> | H <neighbour information> };

<neighbour information> ::= <first frequency: bit(5)> <cell info>
{ H <info field> }** L <spare padding>;

<cell info> ::= <bsic : bit(6)> { H <cell parameters> | L };

<cell parameters> ::= <cell barred> | L <further cell info>;

<cell barred> ::= H;

<further cell info> ::= <la different>
<ms txpwr max cch : bit(5)>
<rxlev access min : bit(6)>
<cell reselect offset : bit(6)>
<temporary offset : bit(3)>
<penalty time : bit(5)> ;

<la different> ::= { H <cell reselect hysteresis : bit(3)> | L };

<info field> ::= <next frequency>** L <differential cell info>;

<next frequency> ::= H;

<differential cell info> ::= { H <BCC : bit(3)> | L <bsic : bit(6)> }
{ H <diff cell pars> | L };

<diff cell pars> ::= <cell barred> | L <further diff cell info>;

<further diff cell info> ::= <la different>
{ H <ms txpwr max cch : bit(5)> | L }
{ H <rxlev access min : bit(6)> | L }
{ H <cell reselect offset : bit(6)> | L }
{ H <temporary offset : bit(3)> | L }
{ H <penalty time : bit(5)> | L };

Static and dynamic conditions:

1) Information from the last received neighbour cell description in SYSTEM INFORMATION TYPE 5/5bis/5ter is necessary for the mobile station to interpret <neighbour information>. If <BA ind> is different from the last received BA IND value indicated in SYSTEM INFORMATION TYPE 5/5bis/5ter, <neighbour information> cannot be interpreted by the mobile station.

2) If the correspondence between neighbour cell frequencies and sets of pairs (BSIC, cell information) cannot be established following the rules below, or if more than one set of such pairs corresponds to one neighbour cell frequency, the mobile station shall diagnose an imperative message part error.

Attributes, field contents:

1) <cell info> defines a BSIC given by <bsic : bit(6)>. It also defines cell information. If <cell parameters> is contained in <cell info>, this cell information is the cell information given by <cell parameters>; if <cell parameters> is not contained in <cell info>, this cell information is empty.

2) <differential cell info> defines a BSIC given by <bsic : bit(6)> or by <BCC : bit(3)>, see below. It also defines cell information. If <diff cell pars> is contained in <differential cell info>, this cell information is the cell information given by <diff cell pars>; if <diff cell pars> is not contained in <differential cell info>, this cell information is empty.

3) <cell parameters> either indicates a barred cell (by presence of <cell barred>)or specifies cell information given by <further cell info>.

4) Each occurrence of <diff cell pars> either indicates a barred cell (by presence of <cell barred>)or specifies cell information given by <further diff cell info>.

5) <further cell info> specifies cell information given by its components:

– <la different>;

– <ms txpwr max cch : bit(5)>;

– <rxlev access min : bit(6)>;

– <cell reselect offset : bit(6)>;

– <temporary offset : bit(3)>;

– <penalty time : bit(5)>;

as defined below.

6) For each occurrence of <further diff cell info>, a cell information is defined. This information is given by <la different> and remaining cell information established as follows:

The remaining cell information defined for the first occurrence of <further diff cell info> consists of the cell information given by its actual components plus the cell information specified by <further cell info> corresponding to its missing components.

The remaining cell information defined for a later occurrence of <further diff cell info> consists of the cell information given by its actual components plus the remaining cell information corresponding to its missing components which is defined for the previous occurrence of <further diff cell info>.

Here, the

"actual components" of an occurrence of <further diff cell info> denotes those parameters among:

– <ms txpwr max cch : bit(5)>;

– <rxlev access min : bit(6)>;

– <cell reselect offset : bit(6)>;

– <temporary offset : bit(3)>;

– <penalty time : bit(5)>;

which are present in that occurrence.

"missing components" of an occurrence of <differential cell info> denote those parameters among:

– <ms txpwr max cch : bit(5)>;

– <rxlev access min : bit(6)>;

– <cell reselect offset : bit(6)>;

– <temporary offset : bit(3)>;

– <penalty time : bit(5)>;

which are not present in that occurrence.

7) Each occurrence of <bsic : bit(6)> specifies a BSIC by encoding its binary representation. <BCC : bit(3)> specifies a BCC by encoding its binary representation; it specifies the BSIC given by that BCC and the NCC of the BSIC specified by the previous occurrence of <BCC : bit(3)> or <bsic : bit(6)>. All occurrences of <bsic: bit(6)> and <BCC : bit(3)> establish a list of BSIC.

8) <first frequency : bit(5)> is the 5 bit binary coding of an integer n with 0 <= n <= 31. It specifies a first frequency number n+1.

9) <SI10 rest octets> defines a correspondence between neighbour cell frequencies and sets of pairs (BSIC, cell information) defining the parameters for cell re-selection of any corresponding neighbour cell with BCCH on that frequency and having that BSIC:

– Let a(1),…, a(n) be the list of neighbour cell frequencies, in the order determined by the mobile station. Let i be the first frequency number specified by <first frequency : bit(5)> (see above).

– The first BSIC and the cell information specified by <cell info> build a pair belonging to the set corresponding to a(i).

– If an m-th occurrence of <info field> is present (where m >=2), having established the correspondence of the (m-1)-th BSIC to a neighbour frequency a(k), the m-th BSIC and following <differential cell info>:

– belong to a(k), if <next frequency> is not present in the m-th occurrence of <info field>;

– belong to a((smod(k+t)), if <next frequency> is present exactly t times in the m-th occurrence of <info field>.

– Here, for an integer j, smod(j) := ((j-1) mod n) + 1.

10) If <la different> contains a <cell reselect hysteresis: bit(3)>, this means that the cell is to be considered by the mobile station to belong to a different location area and that for the cell, the cell reselect hysteresis specified in <cell reselect hysteresis : bit(3)> applies.

11) If <la different> doesn’t contain a <cell reselect hysteresis: bit(3)>, this means that the cell is to be considered by the mobile station to belong to the same location area.

12) For <cell reselect hysteresis : bit(3)>: see sub-clause 10.5.2.4.

13) For <ms txpwr max cch : bit(5)>: see sub-clause 10.5.2.4.

14) For <rxlev access min : bit(6)> see sub-clause 10.5.2.4.

15) For <cell reselect offset : bit(6)>: see sub-clause 10.5.2.35.

16) For <temporary offset : bit(3)>: see sub-clause 10.5.2.35.

17) For <penalty time : bit(5)>: see sub-clause 10.5.2.35.

RA, Random Access Information (octet 2 and octet 3)
When included in an IMMEDIATE PACKET ASSIGNMENT message sent in response to an EGPRS MULTILATERATION REQUEST message indicating ‘Access Burst’ method the 8 least significant bits of this field are used and contain the value of the ‘Short ID’ field included in the corresponding message (see 3GPP TS 44.060 [76]).

When included in an IMMEDIATE PACKET ASSIGNMENT message sent in response to an EGPRS MULTILATERATION REQUEST message indicating ‘Extended Access Burst – part 1’ the least significant 4 bits of this field are used and contain the value of the ‘Random ID Low’ field included in the corresponding message.

When included in an IMMEDIATE PACKET ASSIGNMENT message sent in response to an EGPRS MULTILATERATION REQUEST message indicating ‘Extended Access Burst – part 2’ all 12 bits of this field are used and contain the value of the ‘Random ID High’ field included in the corresponding message.

RA Type, Random Access Type (octet 2)

This field indicates the type of access request the IMMEDIATE PACKET ASSIGNMENT message sent in response to. This field is coded as follows:

Bits

00

T1′ (octet 3)
The T1′ field is coded as the binary representation of (FN div 1326) mod 32.

T3 (octet 3 and 4)
The T3 field is coded as the binary representation of FN mod 51. Bit 3 of octet 3 is the most significant bit and bit 6 of octet 4 is the least significant bit.

T2 (octet 4)
The T2 field is coded as the binary representation of FN mod 26.

NOTE 1: The frame number, FN modulo 42432 can be calculated as 51x((T3-T2) mod 26)+T3+51x26xT1′

10.5.2.88 EC Packet Channel Description Type 3
