Problems solved by technology

[0009] However, the following problems exist in the prior art: if a cell belongs to multiple MBSFN areas, that is, multiple MBSFN areas have overlapping areas, then there are multiple MCCHs in this cell, and each MCCH channel corresponds to one MBSFN area
If multiple MBSFN areas belong to different MCEs, each MCE configures radio resources for the eNB according to its own needs. When the eNB allocates radio resources for the MCCH according to the instructions of the MCE, it may allocate the same resource for different MCCHs, or allocate the same resource for the same MCCH. Different resources are allocated, resulting in resource conflicts

Embodiment 1

[0078] This embodiment describes the situation where multiple MBSFN areas in the same MCE overlap, that is, a cell includes multiple MBSFN areas, and the multiple MBSFN areas belong to the same MCE, image 3 It is a schematic flowchart of a method for allocating radio resources for MCCH in Embodiment 1 of the present invention, as shown in image 3 As shown, the method includes:

[0079] Step 301: Multiple overlapping MBSFN areas in a cell belong to the same MCE.

[0080] Here, multiple overlapping MBSFN areas belong to the same MCE, which means that the MCE IDs corresponding to the MBSFN areas are the same.

[0081] Step 302: The MCE divides radio resources for multiple MBSFN areas in the cell, and sends control signaling to the eNB through the M2 interface, and the control signaling includes resource configuration information related to MBSFN transmission in the eNB, and other information related to MCCH relevant information.

[0082] Here, the MCE allocating radio resour...

Embodiment 2

[0091] In this embodiment, multiple MBSFN areas in different MCEs overlap, and there is no situation where a certain MCE area completely includes other MCE areas. Figure 4 It is a schematic flowchart of a method for allocating radio resources for MCCH in Embodiment 2 of the present invention, as shown in Figure 4 As shown, the method includes:

[0092] Step 401: Multiple MBSFN areas in a cell belong to different MCEs, and no MCE may contain other MCEs.

[0093] Figure 5 It is a schematic diagram of MCE distribution in Embodiment 2 of the present invention, Figure 5 There are 3 MCEs in , and some of the 3 MCEs overlap, but none of the MCEs can contain other MCEs.

[0094] Step 402: Select an MCE as an initial MCE, and the MCE allocates radio resources for the corresponding MBSFN area.

[0095] Here, the initial MCE may be an MCE with the lowest MCE ID number, or the highest MCE ID number, or a random MCE, but is not limited to the above MCE.

[0096] Generally, conside...

Embodiment 3

[0128] In this embodiment, multiple MBSFN areas in different MCEs overlap, and there is a situation where a certain MCE area completely includes other MCE areas. Figure 7 It is a schematic flowchart of a method for allocating radio resources for MCCH in Embodiment 3 of the present invention, as shown in Figure 7 As shown, the method includes:

[0129] Step 701: Multiple MBSFN areas in a cell belong to different MCEs, and one MCE may contain other MCEs.

[0130] Figure 8 It is a schematic diagram of MCE distribution in Embodiment 3 of the present invention, Figure 8 There are 3 MCEs in , among which MCE1 has the largest range, including the range of MCE2 and MCE3.

[0131]Step 702: Select the MCE with the largest range in step 701 as the master MCE (master MCE), and the master MCE allocates radio resources for the MCCH of the corresponding MBSFN area.

[0132] The allocating radio resources refers to allocating eNB radio resources;

[0133] Step 703: the master MCE sen...

Abstract

The invention discloses a method for distributing radio resources for a multicast control channel (MCCH). If a plurality of multimedia broadcast multicast service single frequency network (MBSFN) areas in a cell belong to the same multi-cell / multicast coordination entity (MCE), the MCE divides radio resources in the plurality of MBSFN areas; if the plurality of MBSFN areas in the cell belong to different MCEs, the MCE divides the radio resources through coordination; and the MCE transmits the radio resource division situation to an evolution base station (eNB) and the eNB distributes the radio resources for the corresponding MCCH. The invention further discloses a system for distributing the radio resource for the multicast control channel. As the MCE to which the plurality of MBSFN areas belong divides the radio resources for the MBSFN areas, or the plurality of MCEs to which the plurality of MBSFN areas belong divide the radio resources through coordination, the problem of conflict of resource configuration of MCCH corresponding to the overlapped MBSFN areas can be solved and fair and reasonable configuration can be realized.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and system for allocating wireless resources for multicast control channels. Background technique [0002] In order to effectively utilize mobile network resources, 3GPP proposed Multimedia Broadcast Multicast Service (MBMS), which provides a point-to-multipoint service in which one data source sends data to multiple users in a mobile network to realize network resource sharing , improve the utilization of network resources, especially the precious air interface resources. In the long term evolution (Long Term Evolution, LTE) network, the researched MBMS technology is called Evolved Multimedia Broadcast Multicast Service (Evolved MBMS, E-MBMS). [0003] In the existing LTE technology, the logical channel of the MBMS service is a multicast traffic channel (Multicast TrafficCHannel, MTCH), each MTCH corresponds to an MBMS service session, and multiple MTCH chan...
