This will cause the UE may not be able to receive the control information of all the services it has subscribed to or is interested in
[0008] In addition, how to distribute the MCCH control information of EMBMS is still blank in the communication standard

Embodiment Construction

[0042] The present invention will be described in detail below with reference to the accompanying drawings.

[0043]In the EMBMS technology, the control information sent on the MCCH can be divided into cell-specific information and MBSFN-specific information according to the principle of whether it can be combined. Cell-specific information refers to information sent in units of cells, that is, the content of such information sent in each cell may be different, so it cannot be combined; MBSFN-specific information is information sent in MBSFN areas. This type of information sends the same content in all cells in the same MBSFN area, so it can be combined in the MBSFN area.

[0044] The control information sent on the MCCH generally includes:

[0045] - EMBMS announcement information, which should be cell-specific due to the following reasons: on the one hand, the network may offer different EMBMS services in different cells; on the other hand, even for the same service, UE act...

Abstract

This invention provides a MCCH control information sending method for EMBMS, including steps as follows: classifying the control information into N-MCCH configuration information, N-MCCH announcement information, S-MCCH single community business control information and M-MCCH multiple communities business control information; configuring the classified information into hierarchical community system broadcasting information, N-MCCH, M-MCCH and S-MCCH control information; respectively sending the community system broadcasting information, N-MCCH, S-MCCH and M-MCCH hierarchical control information on an air interface, BCCH, N-MCCH, M-MCCH and S-MCCH. This invention further provides a receiving method of control information for EMBMS, including steps as follows: reading the community system broadcasting information; reading the configuration information of N-MCCH in the community system broadcasting information; reading the information on N-MCCH; obtaining useful MBMS business list; if interesting in the single community business, then reading the information on S-MCCH; if interesting in the multiple communities businesses, then reading the information on M-MCCH.

Description

technical field [0001] The present invention relates to MBMS, and more specifically, the present invention relates to a method and a sending device for MCCH control information of Evolved MBMS (EMBMS). The present invention also relates to a receiving method and receiving device for MCCH control information of evolved MBMS. Background technique [0002] 3GPP launched the 3G Long Term Evolution research project (Long Term Evolution) in 2005, that is, LTE, with the evolved access technology (E-UTRA, Evolved-UTRA) and access network (E-UTRAN), continuously providing services for operators and users Increased demand for better support. It is clearly proposed in the LTE project that the evolved MBMS service (E-MBMS) should be supported. MBMS (Multimedia Broadcast / Multicast Service) is a service introduced in 3GPP Re1.6, which refers to a point-to-multipoint service in which one data source sends data to multiple users, thereby realizing network (including core network and acces...
