29、nd GSNs for a PDP address Signalling message: GTP signalling messages are exchanged between GSN pairs in a 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,

30、from an MS or a network node in an external packet data network. A T-PDU is the payload that is tunnelled in the GTP tunnel Tunnel Endpoint Identifier (TEID): this field unambiguously identifies a tunnel endpoint in the receiving GTP-U or GTP-C protocol entity. The receiving end side of a GTP tunnel

31、 locally assigns the TEID value the transmitting side has to use.

45、to support the case when Network-Requested PDP Context Activation procedures are used and an IM_GSN does not have a SS7 MAP interface.
