Embodiment Construction

[0022] The present invention is a system and method for minimizing the signal load caused by the exchange of information between adjacent cells transmitting the same session. The present invention is also directed to reducing the time required to send MBMS neighbor cell information messages in the serving cell when higher levels of signaling occur.

[0023] Referring to FIG. 2 , shown therein is a simplified block diagram of an embodiment of an exemplary wireless communication system 1 including a plurality of mobile terminals or mobile stations 10 . Two mobile stations (MS) 10 are shown, one designated as MS#1 and the other designated as MS#2. Figure 2 also shows an exemplary network operator 2 having, for example, a Mobile Switching Center (MSC) 3, at least one Base Station Controller (BSC) 4 for connecting to a communication network such as the Public Switched Telephone Network (PSTN), and A plurality of base transceiver stations (BTS) 5 which transmit to mobile stations 1...

Abstract

A system and method for minimizing signalling loads due to mutual exchanges of information between neighboring cells in which the same session is transmitted, and for reducing the time required to transmit MBMS neighbor cell information messages in a serving cell when a higher level of signalling occurs, wherein all broadcast control channel (BCCH) carriers indicated in a BCCH allocation are monitored by a mobile station (MS). A list of the cells having the strongest non-serving carriers is updated as often as the duration of the running average for measurements of the BCCH allocation. Base transceiver station identity codes (BSICs) and neighboring cell indexes of BCCH carriers are added to an uplink radio link control / medium access control (RLC / MAC) message that is transmitted to a network. As a result, the network is provided with the identity of which cell the mobile station is most likely to reselect to upon reception of the uplink RLC / MAC control message carrying the BSICs and neighboring cell indexes of the neighboring non-serving BCCH carriers of the mobile station.

Description

[0001] related application [0002] This application claims priority to US Provisional Application Serial No. 60 / 609,787, filed September 14,2004. technical field [0003] The present invention is directed to a system and method for transmitting / receiving data during broadcast mode and multicast mode, and more particularly to a method for exchanging information between adjacent cells in which a session is transmitted The resulting signaling load is minimized and used to reduce the time required to transmit MBMS Neighbor Cell Information messages in the serving cell when higher levels of signaling occur. Background technique [0004] MBMS (Multimedia Broadcast / Multicast Service) is a unidirectional point-to-multipoint (p-t-m) multicast / broadcast service in which data is transmitted from a single source entity to a group of users located in a specific area. MBMS may include options for unidirectional p-t-m bidirectional point-to-point (p-t-p) transmission of multimedia d...
