6.1 General
IE type value used in Sv Message is defined in TS 29.274 [3]. The IE format is coded as per GTP in TS 29.274 [3].
Table 6.1 shows the IEs used for SRVCC. Within information elements, certain fields may be described as spare. These bits shall be transmitted with the value set to 0. To allow for future features, the receiver shall not evaluate these bits.

6.2 STN-SR
STN-SR is defined in 3GPP TS 23.003 [4]. STN-SR is transferred via GTP tunnels. The sending entity copies the value part of the STN-SR into the Value field of the STN-SR IE. The STN-SR IE is coded as depicted in Figure 6.2-1. Octet 5 contains the Nature of Address and Numbering Plan Indicator (NANPI) of the "AddressString" ASN.1 type (see 3GPP TS 29.002 [11]). Octets 6 to (n+4) contain the actual STN-SR (digits of an address encoded as a TBCD-STRING as in the "AddressString" ASN.1 type). For an odd number of STN-SR digits, bits 8 to 5 of the last octet are encoded with the filler "1111".

6.3 Source to Target Transparent Container
The Source to Target Transparent Container contains information that shall be transferred transparently by CN entities from the source RAN to the target RAN.
When the target network is GERAN, the Transparent container field contains the value part of the Old BSS to New BSS Information IE defined in 3GPP TS 48.008 [8], i.e. octets 3 to n, excluding octet 1 (Element ID) and octet 2 (Length).
When the target network is UTRAN, this container carries the Source RNC to Target RNC Transparent Container IE defined in 3GPP TS 25.413 [9]. The Transparent container field contains a transparent copy of the corresponding ASN.1/PER IE (see subclauses 8.2.2 and 8.48 in 3GPP TS 29.274 [3]).
When the target network is E-UTRAN, the container carries the Source eNB To Target eNB Transparent Container IE defined in 3GPP TS 36.413 [14]. The Transparent container field contains a transparent copy of the corresponding ASN.1/PER IE (see subclauses 8.2.2 and 8.48 in 3GPP TS 29.274 [3]).
The receiver of this Information Element shall ignore the length of the transparent container encoded in octet 5 and shall derive the actual length of the container from the length encoded in octets 2 to 3 minus 1.
For backward compatibility, the sender of this Information Element shall set the octet 5 to the actual length of the transparent container if the size of the container is smaller or equal to 255 octets, and to the value "255" otherwise.

6.5 MM Context for E-UTRAN (v)SRVCC
The MM Context information element contains mobile station classmarks, supported codec list, and the security parameters that are necessary for the MSC server to setup the ciphering connection (and integrity protection for 3G) with the target access for (v)SRVCC. CS ciphering keys parameters: CKSRVCC, IKSRVCC, and eKSI for E-UTRAN (v)SRVCC are defined in 3GPP TS 33.401 [6].
Mobile Station Classmark 2, Mobile Station Classmark 3, and Supported Codec List information Elements indicate the supported encryption algorithms for GERAN access and CS supported codecs. The coding of Mobile Station Classmarks and Supported Codec List fields include the IE value part as it is specified in 3GPP TS 24.008 [7].
eKSI shall be coded as bits 1 to 3 of the NAS Key Set Identifier IE in TS 24.301 [12].For an emergency call without an authenticated IMSI, the source MME shall set the key sequence value of the eKSI to the value ‘111’ and CKSRVCC and IKSRVCC to all 0’s in binary.
