Description

The set command controls the presentation of unsolicited result code +CMICO: <Current_MICO_Mode>[,<RAAI>,<SPRT>[,<Allocated_Active_Time>]] when <n>=1 and there is a change in the current MICO mode. The parameters <RAAI> and <SPRT> and optionally <Allocated_Active_Time>, are returned when <Current_MICO_Mode>=1. When <n>=2, a special form of the set command enables the UE to request the use of MICO mode from the network or re-negotiate the use of MICO mode from the network and optionally request an active timer value, during the registration procedure (see 3GPP TS 24.501 [161], clause 5.3.6 and clause 5.5.1).

Refer clause 9.2 for possible <err> values.

The command should be abortable when <n>=2, when the use of MICO mode is requested or re-negotiated from the network.

The read command returns the current settings of <n>, <Requested_MICO_Mode> and <Requested_Active_Time>. The command also returns the current values of <Current_MICO_Mode>, <RAAI>, <SPRT>, <Requested_Active_Time> and <Allocated_Active_Time> if available (see 3GPP TS 24.501 [161] clause 9.11.3.31).

The test command returns values of supported <n>s and <Requested_MICO_Mode>s as compound values.

Defined values

<n>: integer type

0 disable unsolicited result code +CMICO: <Current_MICO_Mode>[,<RAAI>,<SPRT>[,<Allocated_Active_Time>]]

1 enable unsolicited result code +CMICO: <Current_MICO_Mode>[,<RAAI>,<SPRT>[,<Allocated_Active_Time>]]

2 MICO mode is requested or re-negotiated from the network. There will be no change in the current setting of <n>, enabling or disabling of unsolicited result code +CMICO: <Current_MICO_Mode>[,<RAAI>,<SPRT>[,<Allocated_Active_Time>]]

<Requested_MICO_Mode>: integer type; indicates the requested MICO mode, see 3GPP TS 24.501 [161], clause 5.5.1.

0 triggers the UE to request stopping the use of MICO mode

1 triggers the UE to request the use of MICO mode

<Requested_Active_Time>: string type; one byte in an 8 bit format. Requested Active Time value (T3324) to be allocated to the UE. The <Requested_Active_Time> value is coded as one byte (octet 3) of the GPRS Timer 3 information element coded as bit format (e.g. "01000111" equals 70 hours). For the coding and the value range, see the GPRS Timer 3 IE in 3GPP TS 24.008 [8] Table 10.5.163a/3GPP TS 24.008. See also 3GPP TS 24.501 [161] clauses 5.3.6 and 5.5.1. The default value, if available, is manufacturer specific.<Current_MICO_Mode>: integer type; indicates the current MICO mode, see 3GPP TS 24.501 [161], clause 5.3.6.

0 indicates that the use of MICO mode is not allowed by the network

1 indicates that the use of MICO mode is allowed by the network

<RAAI>: integer type; only present when <Current_MICO_Mode>=1. Indicates the registration area allocation indication, see 3GPP TS 24.501 [161] clause 9.11.3.31.

0 indicates to the UE that all PLMN registration areas are not allocated

1 indicates to the UE that all PLMN registration areas are allocated

<SPRT>: integer type; only present when <Current_MICO_Mode>=1. Indicates the use of the Strictly Periodic Registration Timer, see 3GPP TS 24.501 [161] clause 9.11.3.31.

0 indicates to the UE that the strictly periodic registration timer is not being used

1 indicates to the UE that the strictly periodic registration timer is being used

<Allocated_Active_Time>: string type; one byte in an 8 bit format. Only present when <Current_MICO_Mode>=1. Indicates the Active Time value (T3324) assigned by the network. The <Allocated_Active_Time> value is coded as one byte (octet 3) of the GPRS Timer 3 information element coded as bit format (e.g. "01000111" equals 70 hours). For the coding and the value range, see the GPRS Timer 3 IE in 3GPP TS 24.008 [8] Table 10.5.163a/3GPP TS 24.008. See also 3GPP TS 24.501 [161] clauses 5.3.6 and 5.5.1.
