Method for notifying receiver configuration information of shared downlink public service channel

Abstract

The invention discloses a method for informing a receiver the collocation information of a share descending public traffic channel. A corresponding relationship is arranged in advance between a default id and public radio bearing (RB) default collocation information; the default id is carried in a multimedia broadcast multicast service (MBMS) public point to multi-point (p-t-m) RB information sent to UE by the universal terrestrial radio access network (UTRAN) so as to show the public RB default collocation information corresponding to the id; and at last, when the default id is carried in the MBMS current subdistrict p-t-m RB information received by the UE, the corresponding public RB default collocation information is consulted by the UE according to the corresponding relationship between the default id and the public RB default collocation information. The application of the invention can reduce the vent burden and the power consumption of a time slot in which an MBMS p-t-m control channel (MCCH) is arranged.

Description

technical field [0001] The invention relates to multimedia broadcast / multicast service (MBMS) technology, in particular to a method for notifying receivers of configuration information of a shared downlink common service channel. Background technique [0002] The Third Generation Partnership Project (3GPP) standardized MBMS as part of the sixth edition of its technical standards, expecting operators to provide new multimedia services through broadcast and multicast technologies, such as news, business information, sports programs Wait. [0003] MBMS is designed to allow a sender to simultaneously distribute the same multimedia data to multiple receivers using the same wireless channel, thereby effectively utilizing wireless resources. The above-mentioned transmission from one sender to multiple receivers is called: point-to-multipoint (p-t-m) transmission. MBMS defines some new procedures to support p-t-m transmission, and the key point is that the universal mobile communi...

Problems solved by technology

This makes: on the one hand, since various available MBMS public p-t-m RB configuration information is carried in the MBMS public p-t-m RB information message, it needs to occupy more transmission resources, thereby causing a large burden on the air interface; on the other hand, the The MBMS public p-t-m RB information message is transmitted in the time slot where the MBMS p-t-m service control channel (MCCH) is located. Due to the need to periodically transmit the MBMS public p-t-m RB information message, the power consumption of the time slot where the MCCH is located is relatively large, and at the same time It also causes greater interference to other services / signaling in the local area and neighboring areas
