25、the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z 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 incre

ETSI ETSI TS 129 276 V13.0.0 (2016-01)63GPP TS 29.276 version 13.0.0 Release 131 Scope The present documen

27、t specifies the stage 3 of the Evolved Packet System S101and S121 reference points between the MME and the HRPD 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 procedur

28、es for RIM information exchange between the MME and the HRPD Access Network. It also specifies the S103 interface 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 interf

29、ace are used to set up tunnels on the S103 interface. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

39、agram Protocol VS Vendor Specific 4 General The S101 and S121 reference points are defined between the MME 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 t

40、o cdma2000 HRPD Access to allow for pre-registration and handover signalling with the target system. The 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

41、HSGW and supports the forwarding of DL data during mobility from E-UTRAN to HRPD. Signalling procedures 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 interfa

42、ces shall be based on GTPv2-C, see 3GPP TS 29.274 6 Figure 4.2.0-1. The UDP header and port numbers definitions 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. Layer 1

43、and Layer 2 requirements shall as defined in GTPv2-C, see 3GPP TS 29.274 6 sections 4.2.3 and 4.2.4.

44、 TS 29.274 6 section 4.3. 6 S101 Message Header 6.1 Introduction The S101 Message Header is conformant to 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 S

45、101 interface: - Version - Flags (T = TEID Included) - Message Type - Length 6.2 S101 Message Header The 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 add

46、itional optional header fields or utilities. - Bit 4 (the T bit) may be set to one to indicate that a TEID 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 f

47、ields do not occupy a full eight octets, then spare octets shall be added after the last valid field in 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

48、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 3G

49、PP TS 29.274 6. - Length: This field indicates the length in octets of the payload, i.e. the rest of the packet following the mandatory part of the S101 header (that is the first 4 octets). - Sequence Number: This field enables the target system to identify any missing receipt of messages and is used also for acknowledgement of messages.
