Abstract:
In a telecommunications network wherein a location area (LA1) contains GSM cells (26) having adjacent or neighboring UTMS cells (20), a dedicated procedure is employed to download information about a UTMS cell (20) to a mobile station (16). After entering the location area, the mobile (16) is notified of the presence of the UTMS cell (20). In response to the notice, the mobile (10) is operated to acquire specified information about the UTMS cell (20) from the network, such as frequency and scrambling code combinations, radio access bearer configuration, and information pertaining to intersystem cell selection.

A method and system for load sharing among a plurality of pooled network resources disclosed wherein each network resource includes a load reporting logic for storing load data from the plurality of pooled network resources and for distributing load data from the respective network resource to the plurality of pooled network resources.
Abstract:
A Serving GPRS Support Node (SGSN) handover procedure, for use in a GPRS network, reduces the need for resequencing in the SGSN. This is achieved in that the old SGSN sends a message to the Gateway GPRS Support Node (GGSN), requesting that it stop transmission of data. At that time, the old SGSN transfers to the new SGSN any data which it needs to transmit to the mobile station. The GGSN resumes transmission of data, this time to the new SGSN, when the handover is complete. This reduces the requirement for the new SGSN to resequence the received data. The signal from the old SGSN to the GGSN, requesting it to stop transmission, can be initiated when the old SGSN receives a message from the new SGSN, informing it that the mobile station has moved to a cell served by the new SGSN. Alternatively, the signal can be sent from the old SGSN to the GGSN, on receipt by the old SGSN of a message from the serving base station, informing it that the mobile station has changed to a cell served by another SGSN.
Abstract:
In a method of routing a short message with high or low priority from a service centre to a mobile station in a public land mobile network providing both packet data service and circuit switched service, a choice is made, in advance, as to whether the short message should be received by the mobile station either via a specific one of the services or via any of the services. Based upon said choice in step, the priority of the short message sent from the service centre, and an indication of whether the mobile station is reachable via one, both or none of the services, a route via one of the services, a route via both services or no route at all is selected.

Abstract:
A method is provided that serves to avoid unnecessary re-acquisition of preconfiguration information on a user changing from one public land mobile network (PLMN) to another. This is achieved by, in one embodiment, configuration information relating to a first communication network including an indication as to whether the information is also applicable to a second communications network.
Abstract:
In a method of routing a short message with high or low priority from a service center to a mobile station in a public land mobile network providing both packet data service and circuit switched service, a choice is made, in advance, as to whether the short message should be received by the mobile station either via a specific one of the services or via any of the services. Based upon this choice in step, the priority of the short message sent from the service center, and an indication of whether the mobile station is reachable via one, both or none of the services, a route via one of the services, a route via both services or no route at all is selected. If a route via one of the services is selected, the short message is routed in accordance with the selected route. If a route via both services is selected, the route via the service having a higher preference than the other service is selected, and the short message is routed in accordance with the route via said service having the higher preference. If the routing of the short message to the mobile station is unsuccessful via the route via said service having the higher preference, the short message is routed in accordance with the route via the other service the lower preference.
