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] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary, and are only used to explain the present invention, and cannot be construed as limiting the present invention.

[0043] Such as figure 1 Shown is a schematic diagram of the logical architecture of EMBMS (Evolved Multimedia Broadcast / Multicast Service) on the RAN (Radio Access Network) side of the LTE system, including MCE (MBMS Coordination Entity, MBMS coordination) Entity), eNB (Evolved NodeB) and MBMS GW (Multimedia Broadcast / Multicast Service GateWay, Multimedia Broadcast / Multicast Service GateWay). The interface between the MCE and the eNB is the 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 Service, Multimedia Broa...

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 field of communication technology, and particularly relates to the configuration and delivery of physical resources of a multicast channel. 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 communities. In the LTE (Long Term Evolution) system, MBMS can be provided on both the frequency layer dedicated to MBMS and the frequency layer shared with non-MBMS services. The LTE cell supporting MBMS can be a dedicated MBMS cell or a mixed MBMS / unicast 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, the cell is called an MBMS dedicated cell; when a cell is configured as a f...
