Embodiment Construction

[0042] In order to enable the MBMS radio resource application entity to obtain information related to the single frequency network area, in this embodiment, the MBMS radio resource application entity actively sends an acquisition request and obtains the information related to the single frequency network area, or the MCE actively reports to the abnormal The MBMS radio resource application entity sends information related to the area configuration of the single frequency network.

[0043] In this embodiment, the MBMS radio resource application entity includes an eNB in ​​LTE, a radio network controller (Radio Network Controller, RNC) in UMTS, or a control RNC (CRNC) in a high-speed packet access (High-Speed ​​Packet Access Plus, HSPA+) system .

[0044] The peripheral area (guard area) refers to the area formed by all MBMS radio resource application entities adjacent to the SFN area in the area other than the SFN area, and these MBMS radio resource application entities are adja...

Abstract

The present invention discloses acquiring information method relating to single frequency net zone for implementing MBMS wireless resource application entity obtaining up-to-date information regarding single frequency net zone. The method is: multimedia broadcast and multicasting servings MBMS wireless resource application entity transmit first message of acquiring information related to single frequency net zone; after receiving the first message, multicasting coordinating entity MCE transmit related information corresponding to single frequency net zone to the MBMS wireless resource application entity according to location of the MBMS wireless resource application entity oppositely to single frequency net zone in MBMS service; the MBMS wireless resource application entity receives the information related to single frequency net zone. The present invention also discloses communicating system, MBMS wireless resource application and MCE.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a system for acquiring information related to a single frequency network area (SFN area). Background technique [0002] With the development of wireless network technology, it has developed from a Universal Mobile Telecommunications System (UMTS) to a Long Term Evolution (LTE) system. LTE is an evolution standard based on UMTS network formulated by 3GPP organization. LTE greatly improves the transmission capability of the physical layer and reduces the complexity of the system. [0003] Among them, the technology of Multimedia Broadcast / Multicast Service (MBMS) has also been greatly improved. MBMS was introduced in the R6 version of UMTS for the first time, using the UMTS network to provide MBMS services. MBMS refers to broadcasting or multicasting multimedia data to mobile terminals by sharing a transmission link. MBMS is divided into broadcast and multicast two workin...
