Abstract: A retransmission correction performed by counting means provided in a controlling radio network controller (RNC) within a radio access network in the counting of multimedia service joined mobile terminals located in a cell for a PTP/PTM transmission decision, in the case of a repetition of a multimedia service session. The retransmission correction uses an estimated number of the mobile terminals having received a previous transmission of said multimedia service session from any radio network controller.

Abstract: A radio network control node acts across an Iur interface as a drift radio network control node (262) for a user equipment unit (UE) in a communications system supporting a multimedia broadcast multicast service (MBMS). The drift radio network control node (262) maintains a first counter for counting a number of events occurring at the drift radio network control node (262). Registration of the drift radio network control node (262) with a core network node (30) is advantageously delayed until the counter has exceeded a first threshold value. In one example mode, the number of events occurring at the drift network control node (262) which is counted by the counter is a number of user equipment units for which a Iur linking procedure is performed for the MBMS session.

Abstract: A retransmission correction performed by counting means (70) provided in a controlling radio network controller (RNC) (4a-c) within a radio access network (3) in the counting of multimedia service joined mobile terminals (7) located in a cell (6) for a PTP/PTM transmission decision, in the case of a repetition of a multimedia service session. The retransmission correction uses an estimated number of the mobile terminals having received a previous transmission of said multimedia service session from any radio network controller.

Abstract: In a system and method of adapting an ECSD connection, interruption times and data loss due to a change in the modulation, coding scheme, and number of timeslots of the connection may be minimized or eliminated. The interruption times and data loss may be minimized or eliminated by allocating a peak number of substreams for a given mobile radio connection based on a user requested data rate and/or the number of timeslots used to realize the user requested data rate. Data loss may also be minimized or eliminated by using in-band signaling to signal a change in the modulation, coding scheme, and/or number of timeslots.

Abstract: 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 system and method are provided for routing of a USSD message directly from an MSC/VLR to an external node. When a mobile station user enters a service code which the mobile station does not recognize as being associated with a known supplementary service, the mobile station forms a USSD message containing the service code which is sent to a MSC/VLR. If the MSC/VLR determines that the service code is one that is associated with an application residing in an external node, then the MSC/VLR routes the USSD message directly to the external node. Various methods and techniques can be used to provide the address of the external node to the MSC/VLR.

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