Abstract
The invention provides a method for telling an MBSFN subframe configuration, which comprises the following steps: an evolved Node B sends a neighbor cell list to a Multi-cell/multicast Coordination Entity (MCE) of Multimedia Broadcast and Multicast Services (MBMS) in an M2 interface message; the MCE compares the MBSFN subframe configuration corresponding to each neighbor cell in the neighbor cell list with the MBSFN subframe configuration of the evolved Node B, and sends the comparison result to the evolved Node B. By using the invention, the service cell can know the MBSFN subframe configuration conditions of neighbor cells and reasonably use resources based on the configuration modes, and therefore, interference between cells is effectively reduced, and system capacity and efficiency are improved.

Embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Below by the embodiment that is described with reference to the drawings is exemplary, only is used to explain the present invention, and can not be interpreted as limitation of the present invention.
The present invention mainly is mutual by between eNB and the MCE to make eNB know the MBSFN sub-frame configuration situation of adjacent area, and according to the rational utilization of resources of configuration mode income, thereby effectively reduce the interference of minizone, and improve power system capacity and efficient.
As shown in Figure 2, the method flow diagram for the configuration of the informing MBSFN subframe of the embodiment of the invention may further comprise the steps:
Step S201, when cell initial was set up, eNB obtained the adjacent cell list of oneself.
Step S202, eNB sends to MCE with adjacent cell list in the M2 interface message.Wherein as one embodiment of the present of invention, the specifying information form is as shown in the table:
| Information type | Information description |
| Base station IDs | The sign of base station |
| The Serving cell tabulation | All Serving cells that comprise the base station |
| ＞service cell information | The sign of sub-district |
| ＞neighboring BS information | |
| ??＞＞ECGI | The unique identification of adjacent sub-district |
Step S203, MCE compares to the MBSFN sub-frame configuration of each adjacent sub-district correspondence in the adjacent cell list and the MBSFN sub-frame configuration of eNB, and comparison result is sent to eNB.Particularly, MCE finds corresponding M BSFN subframe configuration information according to the unique identification of adjacent sub-district, and the configuration with Serving cell compares then, by response message comparison result is sent to eNB at last.As a specific embodiment of the present invention, comparison result is sent to eNB specifically can adopt following information format:
| Information type | Information description |
| Base station IDs | The sign of base station |
| The Serving cell tabulation | All Serving cells that comprise the base station |
| ＞service cell information | The sign of sub-district |
| The broadcast message configuration of＞adjacent area | ??BIT?STRING(SIZE(2)) |
Wherein, the adjacent area broadcast message is configured to two bits, and implication is:
00: represent that not every adjacent sub-district all uses the MBSFN sub-frame configuration identical with Serving cell.
10: subclass identical with Serving cell or Serving cell is all used in the MBSFN configuration of all adjacent sub-districts.
01: all adjacent sub-districts all do not have the MBSFN subframe.
Step S204, eNB broadcast comparison result in system message, as this comparison result of broadcasting among the SIB3/SIB5 in system message, make UE to carry out cell measurement according to this comparing result.
As an optional embodiment of the present invention, MCE also needs to preserve the adjacent cell list that eNB sends, and the MBSFN sub-frame configuration of the adjacent sub-district in adjacent cell list regenerates comparison result and sends to eNB when changing.
As the preferred embodiments of the present invention, when the MBSFN sub-frame configuration of the MBSFN sub-frame configuration of adjacent sub-district correspondence and eNB was inconsistent, MCE sent to eNB with the MBSFN sub-frame configuration of adjacent sub-district correspondence in the adjacent cell list.Perhaps, MCE does not compare, and directly the MBSFN sub-frame configuration with adjacent sub-district correspondence in the adjacent cell list sends to eNB.More specifically, can send to eNB by following information format.
| Information type | Information description |
| Base station IDs | The sign of base station |
| The Serving cell tabulation | All Serving cells that comprise the base station |
| ＞service cell information | The sign of sub-district |
| ＞neighboring BS information | Optionally |
| ??＞＞ECGI | Adjacent cell ID |
| ＞＞MBSFN sub-frame allocation mode | MBSFN sub-frame allocation mode |
ENB just can dispatch according to the MBSFN sub-frame configuration of adjacent sub-district correspondence like this, thereby can effectively reduce the interference of minizone, and improves power system capacity and efficient.For example, corresponding eNB is after obtaining on every side adjacent area MBSFN subframe concrete configuration mode, configuration mode according to each sub-district, can define utilization of resources mode, because the MBSFN subframe of adjacent sub-district can become larger interference to this small-sized photograph, therefore according to the adjacent sub-district MBSFN sub-frame configuration situation of recognizing, when scheduling, avoid this sub-district subframe of correspondence that adjacent sub-district is the MBSFN subframe as far as possible.Such as, if adjacent cell configuration MBSFN subframe is 1,3,5, then this eNB uses 2,4,6 subframes as far as possible when scheduling.And must not then use higher coding protection when using this subframe as far as possible; such as changing 1/3 coding into by 2/3 coding; lower modulation levels; such as reducing to QPSK by 16QAM; the near UE of chosen distance eNB dispatches, and parameters such as RSRP that can report according to UE such as eNB or RSRQ confirm whether UE is nearer apart from eNB.Equally, after eNB obtains adjacent sub-district MBSFN sub-frame configuration, also adjacent sub-district MBSFN sub-frame configuration can be broadcast to UE.
