Gateway Location Register: this entity handles location management of roaming subscriber in visited network without involving HLR
28、 Intermediate GSN: this entity is used as serving GSN towards home network and relay some PDU notification messages between serving GSN and Gateway GSN MM context: information sets held in MS and GSNs for a GPRS subscriber related to mobility management (MM) MM Context ID: IMSI or equivalent for use

31、path. The signalling messages are used to transfer GSN capability information between GSN pairs and to create, update and delete GTP tunnels T-PDU: original packet, for example an IP datagram, from an MS or a network node in an external packet data network. A T-PDU is the payload that is tunnelled i

The receiving end side of a GTP tunnel locally assigns the TEID value the transmitting side has to use. The TEID values are exchanged between tun

35、GTP-MAP protocol converting GSN). It includes only the GTP signalling but not data transfer procedures.

No other systems need to be aware of GTP. GPRS MSs ar
37、e connected to a SGSN without being aware of GTP. It is assumed that there will be a many-to-many relationship between IM_GSNs, SGSNs and GGSNs. An IM_GSN may provide service to many GGSNs. A SGSN may provide service to many IM_GSNs and GGSNs. 4 Transmission order and bit definitions Transmission or
38、der and bit definitions on the interface between the IM_GSN and other nodes in the network with GLR are the same as that used in the network without the GLR, see 3GPP TS 29.060. 5 GTP header The GTP header used on interface between the IM_GSN and other nodes in the network with GLR is the same as th
39、at used in the network without the GLR, see 3GPP TS 29.060. 6 GTP Message and Message Formats The only signalling plane exists between the IM_GSN and other nodes (i.e. GGSN, SGSN and GTP-MAP protocol converting GSN). 6.1 Signalling Message Formats GTP defines a set of signalling messages between two
40、 associated GSNs. The signalling messages to be used between the IM_GSN and other nodes are defined in the table below. For the GTP signalling messages to be used on other interfaces see 3GPP TS 29.060. Table 1: Signalling messages Message Type value (Decimal) Signalling message Reference 3 Version

46、.4 Location Management message In the network with the GLR, The optional Location Management messages are defined to support the case when Network-Requested PDP Context Activation procedures are used and an IM_GSN does not have a SS7 MAP interface. GTP is then used to transfer signalling messages be
47、tween the IM_GSN and a GTP-MAP protocol-converting GSN in the GPRS backbone network. The GTP-MAP protocol-converting GSN converts the signalling messages described in this section between GTP and MAP. The MAP messages are sent to and received from the GLR. The GTP-MAP protocol-converting function is
48、 described in 3GPP TS 23.060. The MAP protocol describing the corresponding procedures and messages is described in 3GPP TS 29.002. This alternative method is illustrated in Figure 2.
