Problems solved by technology

[0019] It can be seen from the above that when MBSFN areas overlap, the MBSFN subframe resources corresponding to the MBSFN area in different cells under the same MBSFN area will be configured in different positions in the SAP list, resulting in cells in the same MBSFN area The SAP list index indicated in the MCCH message is different, which leads to inter-cell interference caused by the asynchronous MCCH message

Embodiment 1

[0070] In this embodiment, the control plane message sent by the MCE to the eNB carries the following information:

[0071] 1) A set of SAP content information, each SAP content information includes: SAP cycle information in units of radio frames or 10ms, SAP offset information in units of radio frames or 10ms, and MBSFN subframe bitmap information. In this embodiment, the set of SAP information includes SAP-1 and SAP-2.

[0072] 2) The location information of one or a group of SAPs, used to indicate the location of the corresponding SAP content information in the SAP list carried in the cell system message, preferably, the location information is the location information of each SAP in the group of SAPs in the cell The index number of the SAP list in the system message. In this embodiment, the location information of SAP-1 is the index number P1, and the location information of SAP-2 is the index number P2.

[0073] 3) carry the operation information of the SAP, and the ope...

Embodiment 2

[0080] In this embodiment, the control plane message sent by the MCE to the eNB carries the following information:

[0081] 1) A set of SAP content information, including SAP-1 and SAP-2. Wherein SAP-1 includes: SAP cycle information in units of radio frames or 10ms, SAP offset information in units of radio frames or 10ms, and MBSFN subframe bitmap information; SAP-2 does not include any information.

[0082] 2) The location information of one or a group of SAPs, used to indicate the location of the corresponding SAP in the SAP list carried in the cell system message, preferably, the location information is the first SAP in the group of SAPs in the cell system Location information in the SAP list in the message. In this embodiment, the position information is the index number P1.

[0083] 3) carrying SAP operation information, and the operation information is one or more of the following operations: clearing, subframe deletion, subframe merging, and covering. Optionally, ea...

Abstract

The invention discloses a method for synchronous subframe resource allocation of a multimedia broadcast single frequency network (MBSFN). The method comprises the following steps: a mutli-cell / multicast coordination entity (MCE) transmits a control surface message containing subframe allocation pattern (SAP) information to an eNB; and the eNB updates an SAP list according to the control surface message, and transmits cell system messages containing the SAP list to cells in the region of the MBSFN indicated by the control surface message. The invention also discloses a system for synchronous subframe resource allocation of an MBSFN. The system comprises the MCE and the eNB. By adopting the method and the system of the invention, the subframe resources of the MBSFN can be synchronously allocated in the region of the MBSFN.

Description

technical field [0001] The invention relates to resource configuration technology in the field of wireless communication, in particular to a multicast single frequency network (MBSFN) subframe resource configuration synchronization method and system in a long term evolution (LTE, LongTerm Evolution) system. Background technique [0002] In order to effectively utilize mobile network resources, 3GPP proposed Multimedia Broadcast and Multicast Service (MBMS, Multimedia Broadcast Multicast Service), which provides a point-to-multipoint service in which one data source sends data to multiple users in a mobile network, and realizes network resources Share and improve the utilization of network resources, especially the precious air interface resources. In the LTE network, the researched MBMS technology is called Evolved MBMS (E-MBMS, Evolved MBMS). [0003] In LTE Frequency Division Duplex (FDD) and LTE Time Division Duplex (TDD), on a mixed carrier, that is, there are both mult...
