Abstract: Providing a mobile terminal with system information which enables the terminal to access one of the cells of a cellular telecommunications system includes transmitting from the telecommunications system to all terminals within the cell, including the terminal, a system information indicator that makes available to the terminal system information to provide access to the system. The system information indicator is transmitted on the broadcast channel (BCH). The system information indicator may be a sub-set of the system information conventionally transmitted on the BCH but which is sufficient to allow the mobile terminal to access the network and obtain in the downlink further system information. Alternatively, the information transmitted in the BCH may be a profile index value which directs the mobile terminal to retrieve from a store of the mobile terminal system information pre-stored on the mobile terminal.

Abstract: This disclosure concerns systems and methods for implementing location based services in communications networks. In one example, when the GMLC of a telecommunications network receives a request for the location of a mobile terminal, an SMLC is interrogated to obtain therefrom, if available, data indicative of the location of the relevant mobile terminal. The mobile terminal may be caused to selectively switch between a GSM radio access network and another access network if no location information is derivable from one of the access networks currently used by the device.

Abstract: A method of controlling an attach procedure of a device 1 to a telecommunications network 140 following receipt of an attach rejection from the telecommunications network, the method including assessing the authenticity of the attach rejection, and selecting a criterion for performing a subsequent attach attempt by the device to the network in dependence upon the authenticity assessment. The authenticity may be assessed by determining whether the rejection was received by an authenticated communication link or a signed message. The authenticity may also be assessed by checking that the cause of the reject is consistent with information held by the device. The selected criterion may be power cycling of the device or the passage of a time period.

Abstract: This disclosure concerns methods and systems for network communications. In one example of such a method, respective groups of cells are first allocated to respective location regions. Next, respective indicators are received from various devices, indicating the identity of the cell occupied by the corresponding device. Additionally, a database is maintained that includes information concerning the location region occupied by each device. In operation, when a device switches from a radio access network to another access network, the other access network receives the indicator of the identity of the cell occupied by the device and, in dependence thereon, selects the location region which the device is deemed to occupy by a core network.
