Telecommunications network

摘要

A method is disclosed for registering a mobile terminal with a cellular telecommunications network, the network having a plurality of location areas and a plurality of extended areas of coverage, each extended area being represented by a list of a subset of cells on one or more the location areas, and the mobile terminal using information about a given one of the location areas to connect to the network. The method comprises transmitting a signal including a temporary identifier, which is unique to the mobile terminal when combined with the location area identifier that identifies the cell in which the temporary identifier was allocated a temporary identifier; transmitting an indication of whether the mobile terminal supports location registration based on extended areas (“soft location registration”); and if soft location registration is supported, performing location registration based on the extended area between the mobile terminal and the network. The above method is compatible with existing deployments of 2G and 3 G networks in both packet switched (PS) and circuit switched (CS) domains.

1. A method for registering a mobile terminal with a cellular telecommunications network, the method comprising:
transmitting a signal including a temporary identifier, which is unique to a mobile terminal when combined with a location area identifier that identifies a cell for which the temporary identifier was allocated; transmitting an indication of whether the mobile terminal is configured to facilitate extended area-based location registration based on an extended area of coverage of the cellular telecommunication network that has a plurality of location areas and a plurality of extended areas of coverage where each extended area is represented by a list of a subset of cells on one or more of the location areas that are of a different bearer technology than other cells on the one or more of the location areas; and if the mobile terminal is configured to facilitate extended area-based location registration, performing location registration based on one of a plurality of extended areas of coverage of a cellular telecommunication network, and wherein the mobile terminal uses information about a given one of the location areas to connect to the network.
