Embodiment Construction

[0038] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0039] Embodiments of the present invention provide an MBMS implementation method and system under the LTE architecture, which is especially suitable for some special MBMS services, such as emergency services. Wherein, the multimedia broadcast multicast service coordinating entity (MCE) mentioned below can be regarded as a logical entity, whether a physical entity is independent depends on the operator's requirement.

[0040] method embodiment

[0041] According to an embodiment of the present invention, a method for implementing an MBMS service under an LTE architecture is provided.

[0042] Such as Figure 4 As shown, the method includes the following processing...

Abstract

The invention discloses an MBMS implementation method under an LTE structure, the method including: a broadcast multicast center sending session start messages to a multimedia broadcast multicast service gateway, wherein the session start messages can bring indication messages whether to carry out radio resource coordination; the multimedia broadcast multicast service gateway judging whether to carry out the radio resource coordination according to the indication messages of the session start messages or network configuration; the multimedia broadcast multicast service gateway sending the session start messages to the e-Node B in the condition of the judgment of no carrying out the radio resource coordination, and the multimedia broadcast multicast service gateway sending the session start messages to a multimedia broadcast multicast service coordination function entity in the condition of the judgment of carrying out the radio resource coordination. According to the invention, to satisfy the requirements of LTE / SAE structure, the BM-SC controls whether the MCE carries out the radio resource coordination according to the characteristics of service, thereby not only satisfying the MBMS service requirements and efficiently reducing the judgment complexity of the MCE carrying out the radio resource coordination.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to the multimedia broadcast multicast service ( Multimedia Broadcast Multicast Service (MBMS) implementation method and system. Background technique [0002] With the development of flat network architecture and the emergence of various high-speed broadband mobile access methods, the evolved wireless communication system can provide higher transmission rates, shorter transmission delays, and lower costs, while supporting 3GPP The mobility between internal access systems and the mobility between 3GPP access systems and non-3GPP access systems, etc., have prompted mobile communication networks to propose the next-generation architecture of LTE / SAE (System Architecture Evolution, System Architecture Evolution) idea. [0003] The current SAE framework such as figure 1 As shown, the network elements in it are: [0004] EUTRAN (Evolved UTRAN, Evolved Radio Access Network...
