Description
Technical field
The present invention relates to wireless communication field, particularly relate to a kind of power information and report, forward and power regulating method, system and equipment.
Background technology
In order to support broadcasting multicast service in the cellular system, multimedia broadcast-multicast service (Multimedia Broadcast andMulticast Service, MBMS) is introduced in 3G (Third Generation) Moblie standardization body (3GPP) R6 standard.The object of MBMS be with a kind of very efficient, economic, mode of sharing for multi-user provides can from point-to-multipoint unidirectional downlink Multimedia data.As one of the most attractive business model in next generation mobile communication field, MBMS is subject to the great attention of operator and equipment vendors.
Long Term Evolution (LTE) normal phases, in Access Network, introduce single frequency network (SFN) transmission means carry out MBMS transmission data, namely in Multicast Broadcast Single Frequency Network (MBSFN Multicast Broadcast SingleFrequency Network, MBSFN) transmission means.MBSFN transmission means carries out the identical business tine of synchronous transmission with same frequency in multiple community at one time.Use this transmission means to save frequency resource, improve the availability of frequency spectrum, its central characteristics is that a service source uses a access network resource to provide the service of identical services content for multiple user.This multiple sectors at same keeps pouring in defeated brought diversity and can solve the problems such as blind area simultaneously, and can increase the reliability of reception, improves coverage rate.
At present, green strategy is carried out energetically by China, implements green strategy and enterprise can be made to obtain comprehensive environmental benefit.It, to the reasonable disposition promoting social resources, realizes sustainable development and has great significance.Thus, in mobile communications network design and deployment, energy-conservationly currently become a large key factor.In MBMS data process of transmitting, how under ensureing that MBMS data receives normal situation, the problem reducing energy consumption is also just placed in front of us.
In LTE system, MBMS transmission is adopted in two ways: single cell transmission mode and multiple cell transmission means (i.e. MBSFN transmission means).When adopting single cell transmission mode, only MBMS transmission data in a cell range.When adopting multiple cell transmission means, in a MBSFN region, the synchronous MBMS transmission data of multiple cell.MBSFN transmission means carries out synchronous transmission with same frequency in multiple community at one time.Use this transmission means to save frequency resource, improve the availability of frequency spectrum.MBSFN transmission means overcomes conventional cell when disposing MBMS, and the UE performance being positioned at cell overlapping region is subject to severe jamming and UE performance with the shortcoming declined gradually away from transmitting base station, and improves the MBMS performance at LTE networking.
In the prior art, based on SFN transmission means MBMS data transmission flow process as shown in Figure 1, mainly comprise following steps:
Step 1: core net determines the scope in SFN region.
Step 2: core net carries out unified Resourse Distribute to the community in determined SFN regional extent, and resource allocation information is sent to the base station corresponding to each community.
Step 3: the resource allocation information configuration broadcast Traffic Channel that each base station is sent according to core net.
Step 4: each base-station node uses fixing maximum transmission power to carry out the synchronized transmissions of MBMS data on the broadcasting service channel of configuration.So-called maximum transmission power is that the received power needed for MBMS data recipient the poorest in this SFN region configures.This poorest received power needed for MBMS data recipient was determined in the system testing stage, such as, the received power be in needed for Cell Edge User can be defined as the received power needed for the poorest MBMS data recipient.
Realizing in process of the present invention, inventor finds to there is following technical problem in prior art:
In existing scheme, each base-station node will carry out the synchronized transmissions of broadcasting service on the same resource.But the MBMS data reception condition in the community of each base station coverage is not identical, determine the power of all base stations by the poorest MBMS data recipient in whole SFN territory, this can make the power of wherein a lot of base station bigger than normal undoubtedly, causes power resource to waste.Further, each base station uses fixing power delivery MBMS data, and flexibility is poor.

Below the present invention is specifically described:
As shown in Figure 5, arrange a RPCS in a network, it can support that WLAN communicates with LTE network equally.It receives the MBMS data received power information of each UE under a community by WLAN link, carries the id information of relevant UE to carry out the power headroom analysis towards community in information; And executing after the power headroom analysis of community, communicated with the eNB belonging to related cell by the communication interface of LTE, the power headroom of notice current area, so that eNB lowers the MBMS data power of related cell, the final object realizing the MBMS data power saving eNB.RPCS workflow is substantially as follows:
Step 1:UE carries out received power detection when receiving MBMS data, and the performance number detected is stored in the WLAN application of UE and the shared data field of LTE application;
Step 2:UE is stored in the performance number reporting of shared data field to RPCS by WLAN link;
Step 3:RPCS carries out statistics and analysis to the MBMS received power of each UE under a community in units of community, selects the minimum power item P of the UE in this community
min=Min (P
uE1, P
uE2..., P
uEk).
RPCS P
mindeduct pre-configured MBMS and correctly receive power demand value P
necessary, obtain power surplus Δ P, i.e. Δ P=(P
min-P
necessary).
The control eNB that RPCS extracts this community based on cell ID identifies; The eNB that RPCS is indicated to eNB mark by LTE communication link (as Operation and Maintenance interface) sends the power surplus Δ P that the eNB calculated has community under its command;
Step 4:eNB is at original transmitted power P
oLDon deduct the transmission power value P that Δ P just obtains new configuration
nEW, i.e. P
nEW=P
oLD-Δ P, and ensure P
nEWbe less than or equal to the specified maximum transmit power value of MBMS data of community.With regard to dynamic conditioning, relevant MBMS sends the power of community like this, saves the overall power resource of LTE Access Network, also just reaches the target of green energy conservation.
Pass through said process, each SFN transmitting community is that the maximal received power needed for the reality of this community carries out MBMS data transmitting on broadcasting service channel, instead of carry out MBMS data transmitting according to the maximal received power in whole MBSFN district, clearly, in MBSFN territory, the transmitting power of most of community can reduce, and reduces the consumption of electric energy.
