摘要:
A method pertaining to a telecommunications system for handling supplementary services for a mobile unit. The system includes a public land mobile network to which the mobile unit has subscribed. The mobile telephone network includes a main switch or gateway switching center to which there is connected a home location register. The mobile unit services are stored in this register. The method includes the steps of sending an authority word belonging to the mobile unit and the identification of the mobile unit to the home location register from a telephone unit in the telecommunications system via a telephone connection intended for handling services; checking the authority word by comparing the word with an authority word known to the home location register; accepting the authority word received from the telephone unit; sending a service handling specification from the telephone unit to the home location register; and performing the specified handling of the service.

A method and node in a communication network for facilitating access by a client terminal to an IMS service from a non-Session Initiation Protocol (non-SIP) compliant access network such as a circuit-switched network. The node receives a request from the client terminal and in response, allocates to the terminal, a Terminal Adapter from a plurality of Terminal Adapters. The node then sends a message to the client terminal reporting the address of the allocated Terminal Adapter.
摘要:
A roaming mechanism enabling a mobile station to roam between a first data packet network utilizing a Mobile IP Method (MIM) and a second data packet network utilizing a Personal Digital Cellular Mobility Method (PMM) is disclosed. A foreign agent (FA) is introduced into the PMM network for enabling a mobile station associated with the MIM network and currently roaming within the PMM network to communicate packet data with an associated home agent (HA). A home agent (HA) is further introduced into the PMM network for enabling a mobile station associated with the PMM network and currently roaming within the MIM network to communicate packet data with an associated FA or Mobile IP Client Emulator (MICE) currently serving the roaming mobile station.
