Problems solved by technology

The length of the message combined with the result of the transmission frequency makes it possible for BSPM to significantly increase the load on the paging (overhead) channel
[0005] In addition, when the mobile station initially updates the overhead information, the lengthy Broadcast Service Parameters message may cause a delay of up to 5 seconds to update the BSPM information
Also, in many cases, the same redundant information is sent on the BSPM every 1.28 seconds, causing unnecessary load on the paging channel and unnecessary processing of the same message by the mobile station

Embodiment Construction

[0027] In this patent document, the following discussed Figures 1 to 6 The various examples used and to describe the principles of the invention are by way of illustration only and should not be construed in any way as limiting the scope of the invention. Those skilled in the art will understand that the principles of the invention may be implemented in any suitably arranged wireless network.

[0028] figure 1 An exemplary wireless network 100 is shown that employs broadcast-multicast services (BCMCS) in an efficient manner in accordance with the principles of the present invention. Wireless network 100 includes a plurality of cell sites 121-123, each comprising one of base stations BS101, BS102 or BS103. Base stations 101-103 communicate with a plurality of mobile stations (MS) 111-114 over code division multiple access channels according to the IS-2000-C standard (ie, CDMA2000 version C). Mobile stations 111-114 may be any suitable wireless device, including conventional...

Abstract

The present invention provides a message sent from a base station to a plurality of mobile stations in a wireless network providing a broadcast multicast service, wherein the message includes: one or more fields for providing and configuring in the base station Configuration information related to the multicast service on each frequency in the coverage area; and a flag for indicating that the message includes all of the one or more fields or only includes the one or more fields with The selection fields for configuration information have been updated.

Description

technical field [0001] The present invention relates generally to a wireless network, and more particularly to an apparatus and method for reducing the load on a paging channel for Broadcast Multicast Service (BCMCS) in a wireless network. Background technique [0002] Early Code Division Multiple Access (CDMA) networks, such as IS-95 networks, carried only a very small amount of data traffic. However, third generation wireless networks such as IS-2000 (also known as CDMA2000) are designed to carry much heavier data traffic loads. IS-2000 network can effectively provide high-speed data services and voice services. However other networks such as 1x EV-DO networks are primarily data systems. If these types of networks are used for both voice and data, then voice is typically carried on a channel adjacent to data traffic. However, IS-2000 (revision C of CDMA2000) carries voice and data on the same carrier. [0003] BCMCS (Broadcast Multicast Service) is a type of new data s...
