Abstract

The invention discloses a multimedia broadcast multicast service single frequency network (MBSFN) optimization self-configuration method. The method comprises the following steps that: an MBSFN control device informs an evolved node base (eNB) to broadcast a feedback instruction to each piece of user equipment (UE) through a multipoint control channel (MCCH) and the eNB indicates each piece of UE to feed back multimedia broadcast multicast service (MBMS) feedback information; each piece of UE feeds back the MBMS feedback information to respective eNB according to the feedback instruction received from the eNB; after receiving the MBMS feedback information transmitted by each piece of UE, the eNB transmits the MBMS feedback information to the MBSFN control device; the MBSFN control device analyzes the received MBMS feedback information to acquire analysis information; and the MBSFN control device and a broadcast multicast-service center (BM-SC) perform cooperative control, so that the MBSFN and / or the BM-SC make a judgment result of performing optimization self-configuration operation on wireless resource in each cell in an MBSFN region corresponding to the MBSFN control device on the basis of the analysis information and a preset strategy. By the method, utilization ratio of the wireless resources can be increased; and continuity of the MBMS is supported.

Description

technical field

[0001] The present invention relates to the field of mobile communication, in particular to a single frequency network optimization self-configuration method and device for an enhanced / evolved multimedia broadcast multicast service (E-MBMS) in an LTE system. Background technique

[0002] A multimedia broadcast multicast service (Multimedia Broadcast Multicast Service, hereinafter referred to as MBMS) proposed by 3GPP (The 3rd Generation Partnership Project) is a broadcast multicast service supporting point-to-multipoint. With the progress of Long Term Evolution (LTE, Long Term Evolution) standardization, 3GPP LTE proposes Enhanced / Evolved Multimedia Broadcast Multicast Service (hereinafter referred to as E-MBMS). 3GPP has clearly defined the concept and framework for E-MBMS at present, and the E-MBMS system in R9 is a broadcast transmission system.

[0003] According to the existing 3GPP technical specifications, the E-MBMS broadcast service adopts the netwo...
