Method and Arrangement Relating to Communications Network Services Request Activation

An arrangement for use in a communications network node comprising a processing unit for handling communication data and communication control information a memory, and an interface unit and communication units, each having a respective connecting interface, characterized by said interface unit is arranged to receive data comprising two sets of tunnelling endpoint identifiers and IP addresses during activation of a subscriber's session information during an active session receiving by said server data comprising two sets of tunnelling endpoint identifiers and IP addresses, a first set of said tunnelling endpoint identifiers comprising tunnelling endpoint identifier for a Radio Network Controller user plane and a second set of said tunnelling endpoint identifiers comprising user plane tunnelling endpoint identifier of said second server in a message comprising tunnel endpoint identity, IP address, Radio Network Controller tunnel endpoint identity and IP address exchanged exchanged between said first and second servers and said processing unit being arranged to process and discard one set of said tunnelling endpoint identifiers and IP addresses relating to a network controller.

An arrangement for use in a communications network node comprising a processing unit for handling communication data and communication control information a memory, and an interface unit and communication units, each having a respective connecting interface, characterized by a communication arrangement generating a message to Gateway GPRS Support Node comprising its tunnel endpoint identity, IP address, Radio Network Controller tunnel endpoint identity and IP address.

A telecommunication infrastructure node comprising a Gateway GPRS Support Node, GGSN, arranged to communicate with a Serving GPRS Support Node, SGSN, said GGSN being arranged to handle data from an external network and said SGSN being arranged to handle communication with a user equipment (MS), characterized by said GGSN being arranged to receive an activation PDP Context comprising two sets of tunnelling endpoint identifiers and IP addresses, a first set of said tunneling endpoint identifiers comprising tunnelling endpoint identifier and IP address for a Radio Network Controller user plane and a second set of said tunnelling endpoint identifiers comprising user plane tunnelling endpoint identifier and IP address and said GGSN being arranged to discard one set of said tunnelling endpoint identifiers and IP addresses corresponding to a network controller and use the other set of tunnelling endpoint identifiers and IP addresses corresponding to said SGSN.

A computer program used in service request procedure in a packet switched telecommunications network, said network comprising a first server arranged to communicate with a second server, said first server being arranged to handle data from an external network and said second server being arranged to handle communication with a user equipment, characterised in that said computer program comprising:

• instruction set for receiving data comprising two sets of tunnelling endpoint identifiers and IP addresses during activation of a subscriber's session information, a first set of said tunnelling endpoint identifiers comprising tunnelling endpoint identifier and IP address for a Radio Network Controller user plane and a second set of said tunnelling endpoint identifiers comprising user plane tunnelling endpoint identifier and IP address and instruction set for discarding one set of said tunnelling endpoint identifiers and IP addresses corresponding to a network controller.
