37、n This document describes the Sv interface related procedures, message parameters and protocol specifications. The Sv messages are based on GTP. The message format, IE coding, and protocol error handling for Sv is per GTP as specified in 3GPP TS 29.274 3. The general rules for IP address and UDP por
38、t number handling for the GTP messages on the Sv interface is per 3GPP TS 29.274 3. 5 Sv Messages and Information Elements 5.1 Introduction The Sv application defines a set of messages between the MME/SGSN and MSC Server to provide SRVCC as defined in 3GPP TS 23.216 2. The Sv message header shall be
39、 conformant to the GTPv2-C Message Header, see 3GPP TS 29.274 3. The messages to be used and the information elements are described in the following sections. ETSI ETSI TS 129 280 V14.0.0 (2017-04)73GPP TS 29.280 version 14.0.0 Release 145.2 Sv Messages 5.2.1 General Sv Messages are used for both th
40、e Inter-RAT handover from IMS based voice service over EPS to CS domain over 3GPP UTRAN/GERAN access or from UTRAN (HSPA) to 3GPP UTRAN/GERAN access and the Inter-RAT handover from IMS based voice and video service over EPS to CS domain over 3GPP UTRAN access. Sv Messages are also used for the Inter
41、-RAT handover from voice service in CS domain over 3GPP UTRAN/GERAN access to IMS based service over LTE or UTRAN (HSPA). Sv Message Type value is defined in 3GPP TS 29.274 3. The message format is coded as per GTP in 3GPP TS 29.274 3. Table 5.2.1: Message types for Sv interface Message Type value (

45、248-255 Reserved for GTPv2 3GPP TS 29.274 3 The GTPv2-C messages shall be sent per UE on the Sv interface. There shall be one pair of TEID-C per UE on the Sv interface. The same tunnel shall be shared for the control messages related to the same UE operation. The TEID field in the SRVCC PS to CS Req
46、uest and in the SRVCC CS to PS Request message header shall be set to “0“ because this is the first message sent between the MME/SGSN and the MSC server to establish the tunnel for a UE. The TEID field in the SRVCC PS to CS Cancel Notification message header shall be set to “0“ if the message is sen
47、t before reception of the acceptance response to the SRVCC PS to CS Request. If the MME/SGSN sends the SRVCC PS to CS Cancel Notification message after the acceptance response to the SRVCC PS to CS Request, the TEID field of the SRVCC PS to CS Cancel Notification message may be set to the MSC Server
48、s TEID value received in the SRVCC PS to CS Response message. Therefore the MSC Server shall be able to accept the SRVCC PS to CS Cancel Notification messages with “0“ or non-zero TEID in the message header. The TEID field in the SRVCC CS to PS Cancel Notification message header shall be set to “0“
49、if the message is sent before reception of the acceptance response to the SRVCC CS to PS Request. If the MSC Server sends the SRVCC CS to PS Cancel Notification message after the acceptance response to the SRVCC CS to PS Request, the TEID field of the SRVCC CS to PS Cancel Notification message may be set to the MME/SGSN TEID value received in the SRVCC CS to PS Response message. Therefore the MME/SGSN shall be able to accept the SRVCC CS to PS Cancel Notification messages with “0“ or non-zer
