Embodiment Construction

[0086] In order to realize the dynamic or semi-static configuration of the SFN area, in this embodiment, the MCE mainly controls and determines the dynamic or semi-static establishment, expansion, and contraction of the SFN area. This embodiment takes dynamic establishment, expansion and contraction of the SFN area as an example for description. The method of semi-statically configuring the SFN area can refer to the method of dynamic configuration.

[0087] For configuration methods, it usually includes static, semi-static and dynamic. Regarding the configuration of the SFN area, static configuration means that the eNB inside the SFN area is fixed and determined by preset configuration information. Dynamic configuration means that the eNB in ​​the SFN area can dynamically change according to the movement of the UE. Semi-static configuration is between dynamic and static, allowing configuration while also allowing changes in SFN area. There is no strict difference between it and dy...

Abstract

The invention discloses a configuration method for single frequency network area, which is used to realize dynamic and semi-static configuration of single frequency network area. The method is: multicast coordinate entity MCE receives message sent by multimedia broadcast and multicast service MBMS wireless resource application entity; the mentioned MCE determines whether to expand single frequency network area based on the message, and ensure MBMS wireless resource application entity that needs to be added into single frequency network area; and sends wireless resource assigning information to MBMS wireless resource application entity that needs to be added into single frequency network area. The invention also discloses a communication system, MCE, MBMS wireless resource application entity and user device.

Description

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