Problems solved by technology

[0018] Since the content of MBSFN in the LTE system specification has not been perfected, although the current specification provides the allocation method of MBSFN subframes on the air interface, it still lacks the method of how to allocate and transfer resources to the MCH through the M2 interface

Embodiment Construction

[0042] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0043] Such as figure 1 Shown is a schematic diagram of the logical architecture of the EMBMS (Evolved Multimedia Broadcast / Multicast Service) on the side of the RAN (Radio Access Network, wireless access network) in the LTE system, including MCE (MBMS Coordination Entity, MBMS coordination entity), eNB (Evolved NodeB, evolved base station) and MBMS GW (Multimedia Broadcast / Multicast Service GateWay, multimedia broadcast multicast service gateway). The interface between the MCE and the eNB is an M2 interface.

[0044] The purpose of the embodiments of the present invention is to propose a resource configuration method for each MBMS (Multimedia Broadcast / Multicast Servi...

Abstract

The invention provides method and device for allocating and delivering an MCH (Multi-cast Channel) physical resource. The method comprises the following steps of: determining the allocation of an MCH physical resource occupied by an MBMS (Multimedia Broadcast Multicast Service) by an MCE (MBMS Coordination Entity), wherein the MCH physical resource comprises an MCH frequency domain resource and an MCH time domain resource; and sending MCH physical resource allocation information indicating the MCH physical resource allocation to an eNB (evolved base station) through an M2 interface, wherein the MCE sends the MCH time domain resource allocation information which indicates the MCH time domain resource allocation and comprises radio frame circulation period information, radio frame bias information and sub-frame allocation information to the eNB through the M2 interface. The method and the device provide a specific resource allocation and delivery technical scheme of the MCH physical resource and perfect the operation mechanism of (multicast Broadcast Single frequency Network).

Description

technical field [0001] The present invention generally relates to the technical field of communication, and in particular relates to the configuration and delivery of physical resources of multicast channels. Background technique [0002] MBMS (Multimedia Broadcast / Multicast Service, Multimedia Broadcast Multicast Service) is used to provide multimedia broadcast and multicast services for users in wireless cells. In an LTE (Long Term Evolution, long-term evolution) system, MBMS can be provided on both a frequency layer dedicated to MBMS and a frequency layer shared with non-MBMS services. An LTE cell supporting MBMS can be an MBMS dedicated cell or an MBMS / unicast hybrid cell. The MBMS service can be transmitted in a single cell or in multiple cells. [0003] The MBMS dedicated frequency layer refers to a frequency layer dedicated to MBMS transmission. When a cell is configured as an MBMS dedicated frequency layer, it is called an MBMS dedicated cell; when a cell is confi...
