26、nt document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z
27、 where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit
28、 is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 129 276 V15.0.0 (2018-07)63GPP TS 29.276 version 15.0.0 Release 151 Scope The present document specifies the stage 3 of the Evolved Packet System S101and S121 reference points between the MME and the HRP
29、D Access Network. The S101 interface supports procedures for Pre-Registration, Session Maintenance and Active handoffs between E-UTRAN and HRPD networks. The S121 interface supports procedures for RIM information exchange between the MME and the HRPD Access Network. It also specifies the S103 interf
30、ace between the Serving GW and HSGW. This User Plane interface is used to forward DL data to minimize packet losses in mobility from E-UTRAN to HRPD. Signalling procedures on the S101 interface are used to set up tunnels on the S103 interface. 2 References The following documents contain provisions

41、ME and the HRPD access, enabling interactions between E-UTRAN Access and cdma2000 HRPD Access. The S101 interface is required to perform procedures related to optimise HO from the E-UTRAN Access to cdma2000 HRPD Access to allow for pre-registration and handover signalling with the target system. The
42、 S121 interface is required to perform procedures related to RIM information exchange between the E-UTRAN Access and cdma2000 HRPD Access. The S103 interface is defined between the Serving GW and HSGW and supports the forwarding of DL data during mobility from E-UTRAN to HRPD. Signalling procedures
43、on the S101 interface are used to set up tunnels on the S103 interface. The requirements for these interfaces are defined in 3GPP TS 23.402 2. The protocol stack used for the S101 and S121 interfaces shall be based on GTPv2-C, see 3GPP TS 29.274 6 Figure 4.2.0-1. The UDP header and port numbers defi
44、nitions shall be as defined in GTPv2-C, see 3GPP TS 29.274 6 section 4. 2.1. The IP header and IP addresses definitions shall be as defined in GTPv2-C, see 3GPP TS 29.274 6 section 4.2.2.

46、o the GTPv2-C Message Header, see 3GPP TS 29.274 6 section 5. All S101 messages shall have a header that includes specific parameters. The following list of header parameters are defined for the S101 interface: - Version - Flags (T = TEID Included) - Message Type - Length 6.2 S101 Message Header The
47、 S101 header is a variable length header. The minimum length of the S101 header is eight octets. Space has been reserved for four flags that may be used in the future to signal the presence of additional optional header fields or utilities. - Bit 4 (the T bit) may be set to one to indicate that a TE
48、ID is present in the header, as per 3GPP TS 29.274 6. The T bit shall be set to zero to indicate that the TEID field shall not be present in any message sent on the S101 interface. If the header fields do not occupy a full eight octets, then spare octets shall be added after the last valid field in
49、the S101 header to complete eight octets. Spare octets and bits shall be set to zero. Always present fields: - Version field: This field is used to determine the version of the S101 protocol. The version number shall be set to 010. - Message Type: This field indicates the type of S101 message. The valid values of the message type are defined in clause 7.1. Note that values chosen for Message Type shall be coordinated with and shall not overlap the Message Type values chosen for GTPv2-C in 3GPP TS 29.274 6. - Length: Thi
