Embodiment 1

[0053] see figure 2 , is a flow chart of Embodiment 1 of the method of the present invention, including:

[0054] S201: The UE parses out the first identifier representing the MBMS paging service on the PDCCH;

[0055] S202: Analyze the second identifier in the PDCCH indicating whether the i-th group of MBMS services arrive;

[0056] S203: When the second identifier indicates that the i-th group of MBMS services has arrived, receive the i-th group of MBMS service notification messages on the PDSCH corresponding to the PDCCH.

[0057] Further, the UE may receive MCCH information from a corresponding MBMS Control Channel (MCCH) according to the MBMS service notification message, learn the carrier carrying MBMS data, and finally monitor the MBMS service from the carrier.

[0058] The present invention aims to provide a brand-new PDCCH channel structure to group MBMS services so that the MBMS service groups can be reasonably carried on the PDCCH, thereby reducing the number of ...

Abstract

The invention discloses a method for paging multimedia broadcasting service, comprising the following steps: resolving to obtain a first mark expressing the paging service of MBMS on PDCCH by a UE; and receiving an MBMS service notification message on the PDSCH corresponding to the PDCCH when the first mark indicates the MBMS paging service, therefore, the invention can ensure that grouping paginginformation of the MBMB can be loaded on a channel through the first mark in a PDCCH channel structure, and the UE can further find out the concrete MBMB service through receiving the PDSCH corresponding to the channel so as to realize the paging for the MBMB in an LTE system. Correspondingly, the invention also provides a device and a system for paging the MBMB.

Description

technical field [0001] The present invention relates to the technical field of long-term evolution (Long Time Evolution, LTE) of mobile communication, and in particular to a paging method, device and system of a multimedia broadcast service (Multimedia Broadcast and Multicast Service, MBMS). Background technique [0002] MBMS technology broadcasts or multicasts multimedia data to user equipment (UE) by sharing a transmission link. The purpose of MBMS service is to provide multi-users with a very efficient, economical and Multi-point unidirectional download multimedia data. In the LTE system, the cells that carry MBMS services are specified. There are two types of cells that can carry MBMS services. The first type is a cell that uses a specific frequency layer. This cell only carries MBMS services, which is called MBMS dedicated carrier; The second type is a common cell, where MBMS services and common services are jointly carried on the same carrier in a coordinated manner, ...
