Method and device for providing MBMS services in integrated E-MBMS system

Abstract

The invention discloses a method and a device for providing MBMS services in an integrated E-MBMS system. The method comprises the following steps: the MBMS services are divided into categories according to service modes and service contents, and each category of MBMS service is matched with a corresponding wireless link allocation strategy; according to the category of a MBMS service request initiated by a user, the corresponding wireless link allocation strategy is selected; according to the situation, an optimized wireless link is finally selected to provide the MBMS services, so the MBMS services are provided in the integrated E-MBMS system. The method and the device can fully utilize the advantage of each network in an integrated network to optimize and use network resources and can provide richer MBMS services.

Description

technical field [0001] The present invention relates to a method and device for wireless link resource management and control in the technical field of wireless communication, in particular to a method and device for providing MBMS services in a converged E-MBMS system. Background technique [0002] Various existing wireless broadcast and multicast network technologies have their own advantages and disadvantages. The pure broadcast single frequency network technology (broadcast can be considered as one-way communication) has the advantages of large audience (usually regardless of the number of users), wide service coverage, and business content. Determined, generally does not provide uplink channels (does not support interactivity), provides economical services, sufficient network resources, and supports mobility through frequency tuning; when providing MBMS (Multimedia Broadcast Multicast Service, Multimedia Broadcast Multicast Service) services based on cellular networks ,...

Problems solved by technology

[0004] Judging from the current technological development, on the one hand, the MBMS service of 3GPP (Third Generation Partnership Project, Third Generation Partnership Project) is committed to using UTRAN (Universal Terrestrial Radio Access Network, Global Terrestrial Radio Access Network) in its own cellular network. network), E-UTRAN (Evolved UTRAN, Evolved Global Terrestrial Radio Access Network) supports MBMS services, and supports the research and standardization of multi-cell and single-frequency networks, and does not involve integration with heterogeneous networks, especially broadcast networks, and Jointly provide relevant service research and standardization issues; broadcast network currently has many standards, but most of them focus on supporting broadcast and multicast services using different standard formats, without considering the business model and related issues of jointly providing broadcast and multicast services with cellular networks On the other hand, in some researches on network convergence, there are research results related to the provision of broadcast services under network convergence, but most of them are based on existing networks, such as GSM (Global System for Mobile communications, Global System for Mobile Communications), UTRAN, and WLAN (Wireless Local Area Network, Wireless Local Area Network) provide uplink backhaul channels for broadcasting, and there is no solution in the integrated E-MBMS (Enhanced Multimedia Broadcast Multicast Service, Enhanced Multimedia Broadcasting Group In the system, it is reasonable to classify the characteristics of MBMS services, and at the same time provide wireless link resource allocation and control based on content and business models, and ensure business continuity.

[0005] In the logical architecture of the E-MBMS system, only the MCE (Multi-cell / multicast Coordination Entity, multi-cell / multicast coordination entity) in the MBMS network is considered, that is, multi-cell and single-frequency The network mode supports MBMS services, and it does not completely solve the problem of network integration and wide-area coverage of MBMS services.
