Embodiment Construction

[0041] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Only the parts that need to be understood to understand the actions of the present invention will be described below, and the description of other parts will be omitted without affecting the key point of the present invention.

[0042] The present invention provides a method for more efficiently transmitting a paging indicator notifying the existence of paging information to a plurality of UEs subscribed to an MBMS service.

[0043] Generally, in a mobile communication system, in order to prevent unnecessary battery consumption, the UE receives a PICH signal from a paging occasion (Paging Occasion, hereinafter referred to as "PO") at any time specified in advance, and when the received PICH signal When the setting value of the paging display (PagingInstance, hereinafter referred to as "PI") is "1", it is confirmed that there is p...

Abstract

The invention provides a method to carry paging indicators which tells whether paging information exists in order to carry the paging information to tell a plurality of UEs to receive specific MBMS services the beginning of the session of the MBMS services and whether the control information relating to MBMS services exists. The invention solves the problems of the method to carry paging indicators in the prior standard that no UE exists corresponding to the paging information or UE batteries are depleted after paging, and so on. In addition, the paging information probably brings necessary burden to lub interface ports. By adopting the invention, when an RNC carries paging indicators, paging cycle information is used to minimize the frequency for the RNC to carry paging indicators to a Node B, and the Node B can carry the paging indicators repeatedly. In order to ensure the paging indicators to be carried reliably, a method to use NBAP control information to carry paging indicators from RNC to the Node B is provided.

Description

technical field [0001] The present invention relates to a multicast multimedia broadcast service (Multimedia Broadcast / Multicast Service hereinafter referred to as 'MBMS service'), and more particularly, to a paging method for providing the MBMS service. Background technique [0002] Today, due to the development of communication technology, the services provided in the Code Division Multiple Access (Code Division Multiple Access; hereinafter referred to as 'CDMA') mobile communication system using broadband (Wideband) not only provide voice services, but also develop into the transmission of packet data, circuit Packet service communication of large volume data such as data and multimedia broadcasting / communication business that can deliver multimedia services. Therefore, in order to support the multimedia broadcasting / communication, MBMS services that provide services from one or more multimedia data sources to a plurality of User Equipment (hereinafter referred to as 'UE'...
