A transmission system for relaying short messages comprising a sender of short messages and a receiver of short messages. The short message sender comprises sending means for sending a deleting short message including at least the address of the receiver and the identifier of a short message to be deleted. The short message receiver comprises identification means for identifying the deleting short message and deletion means for deleting the short message according to the identifier of the short message to be deleted in the deleting short message from the memory intended for the short messages of the receiver.

Transmission system for relaying short messages

The basic idea of the invention is to separate the location area used in the RAN and the reporting area used when reporting the location of the mobile to the core network. The size of the location area is selected preferably in the RAN based on the services used by the subscriber to optimize the use of radio resources. A reporting area comprises one or a plurality of location areas. The size of a reporting area is selected based on the accuracy of location information needed in the core network. The RAN informs the core network when a subscriber moves out of his current location area. The core network and the radio access network negotiate the size of the reporting area prior to the activation of the service. Additionally, the reporting areas can be renegotiated when the service is in the active state.

Location management in a mobile telecommunication system

A cellular radio access network and a location updating in a cordless communications system, in a cellular radio access network ( ), which is connected to one or more core networks ( ) or services (SP to SP ), each of them having a dedicated mobility management. In a cell, identities of all those location areas are broadcast to which said cell belongs. A subscriber terminal (MS) sends to the radio access network only one location updating message irrespective of how many core networks ( ) or services (SP to SP ) have a simultaneously changing location area at a handover from one cell to another. On the basis of the information contained in the location updating message, the network ( ) defines the core networks or services and location areas to which the location updating applies and sends a location updating message informing the new location of the subscriber or the subscriber terminal separately to each defined core network or service.
