Embodiment Construction

[0020] The present invention relates to systems and methods for reducing idle mode power consumption for a mobile station (MS) that has joined a Multimedia Broadcast / Multicast Service (MBMS) session and is waiting for the session to start. FIG. 1 shows a simplified block diagram of an embodiment of an exemplary wireless telecommunications system 1 comprising a plurality of mobile terminals or stations 10 . Two mobile stations (MS) 10 are shown, one designated as MS#1 and the other designated as MS#2. Although two mobile stations are shown, preferably more than two mobile stations are used according to the invention.

[0021] Fig. 1 also shows an exemplary network operator 2, for example having a mobile switching center (MSC) 3 for connection to a telecommunications network such as the public switched telephone network (PSTN), at least one base station controller (BSC) 4 and Physical and logical channels are transmitted to a plurality of Base Transceiver Stations (BTS) 5 of th...

Abstract

A system and method for reducing idle mode power consumption for mobile stations (MS) that have joined a Multimedia Broadcast/Multicast Service (MBMS) session and are waiting for the session to start. The invention is also directed to reducing the power consumption of an MS for which an MBMS session is inactive. In alternative aspects of the invention, the power consumption of mobile stations is reduced in the absence of ongoing MBMS session activity. Reduced power consumption is achieved by eliminating the need to read notification messages from an MBMS specific notification paging group when the notification message is for a different MBMS session than the paging group that the MS has currently joined.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 60 / 611,140, ​​filed September 17,2004. technical field [0003] The present invention relates to systems and methods for transmitting / receiving data during broadcast mode and multicast mode, and in particular to systems and methods for reducing idle mode power consumption for a mobile station (MS) that has Joined a Multimedia Broadcast / Multicast Service (MBMS) session and waited for the session to start. Background technique [0004] MBMS (Multimedia Broadcast / Multicast Service) is a unidirectional point-to-multipoint (p-t-m) multicast / broadcast service in which data is sent 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 data such as text, audio, images, or video from a single source entity to a l...
