초록 ▼

A method of performing a SRNS Relocation in a UMTS network for a given UE, the method comprising sending a Relocation Required message from the serving RNC to the core network and sending a Relocation Request message from the core network to the target RNC, the Relocation Required message containing a RRC Initialisation Information container which is incorporated transparently by the core network into the Relocation Request message, and the RRC Initialisation Information container in turn containing information enabling a mapping to be made between RABs and RBs for the UE.

대표청구항 ▼

1. A method of performing a Serving Radio Network Subsystem (“SRNS”) Relocation for a given User Equipment (“UE”) in a Universal Mobile Telecommunications System (“UMTS”) network between a UMTS radio network and a UMTS core network, in which the UMTS radio network and the UMTS core network are logically separated, the method comprising the steps of:sending a Relocation Required message from the serving Radio Network Controller (“RNC”) to the core network; andsending a Relocation Request message from the core network to the Target RNC;wherein the Relocation Required message contains a Radio Resource Control (“RRC”) Initialization Information container which is incorporated transparently by the core network into the Relocation Request message and the RRC Initialization Information container in turn contains information enabling a mapping to be made between Radio Access Bearers (“RABs”) and Radio Bearers (“RBs”) for the UEwherein the RRC Initialization Information container contains a Radio Bearer Information element, the mapping comprises a RAB identity corresponding to each RB, the RABs and the RBs being identified by RAB and RB identifiers, respectively. 2. A method of performing a Serving Radio Network Subsystem (“SRNS”) Relocation for a given User Equipment (“UE”) in a Universal Mobile Telecommunications System (“UMTS”) network between a UMTS radio network and a UMTS core network, in which the UMTS radio network and the UMTS core network are logically separated, the method comprising the steps of:sending a Relocation Required message from the serving Radio Network Controller (“RNC”) to the core network; andsending a Relocation Request message from the core network to the Target RNC;wherein the Relocation Required message contains a Radio Resource Control (“RRC”) Initialization Information container which is incorpoated transparently by the core network into the Relocation Request message and the RRC Initialization Information container in turn contains information enabling a mapping to be made between Radio Access Bearers (“RABs”) and Radio Bearers (“RBs”) for the UEwherein the mapping information contained in the RRC Initialization Information container comprises NAS binding information.
