Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the accompanying drawings and the specific embodiments.
The present invention is directed in the lte networks, when user carries out voice-and-data business simultaneously, the resource that terminal scheduling two kinds needs can be given in base station, in such cases, in the hot spot region that network capacity is comparatively nervous, it is possible to network congestion can be caused, and then make user communication quality be affected, the problem affecting Consumer's Experience, it is provided that the resource allocation methods of a kind of terminal concurrence business, device and base station.
As it is shown in figure 1, the resource allocation methods of the described terminal concurrence business of the embodiment of the present invention, including:
Step 10, when receiving the first service request of terminal, detects whether to process at least one second service request of described terminal;
Step 20, if the second service request processing described terminal being detected, then judges whether the network at described terminal place is in congestion state;
Step 30, if described network is in congestion state, then limits the resource to described second service request and distributes, and carry out the process of the first service request.
Should be noted that, what present invention is generally directed to is realize voice in the lte networks (described voice bearer is on IP, utilize LTE network to be transmitted) transmission, therefore, described first service request is terminal voice call request under LTE network or video calling request, described second service request is terminal data service request under LTE network, and described data service request can be the renewal of data, the renewal that such as dialogue such as QQ, wechat is reminded; Can also be the download of resource, such as the buffering etc. of video data.
Such scheme of the present invention, when carrying out data processing, when receiving again the request of voice or video calling, adjust the distribution to the resource that terminal traffic is asked, the data service of limiting concurrent according to actual needs, it is ensured that the sufficient distribution of voice or video request resource, this kind of method, ensure that the speech quality of voice, improve the utilization rate of Radio Resource simultaneously, alleviate network congestion.
At this, should be noted that, in the lte networks, 3GPP agreement defines 9 kinds of QCI, in order to indicate the qos requirement of different business, as shown in table 1, as QCI5 carries IMS signaling, QCI1 carries VoLTE voice call, and QCI2 carries video calling, QCI3 carries real-time game business, video traffic etc. in QCI4 carrying non-session.
The definition of different QoS in table 1LTE
By the resource requirement of different business being defined (time delay, packet loss etc.) at core network element, and these information are passed to eNodeB, when user initiates VoLTE voice call requirement, UE connects core net and sets up ERAB (i.e. passage between UE and core net), core net distributes resources of core network to this user, the QCI simultaneously identifying this UE is 1, and inform that eNodeB, eNodeB then dispatch respective wireless resource to UE according to the qos requirement of QCI=1 by S1 mouth (namely core net sets up, with eNodeB, the port being connected).
When user carries out the voice and video call of VoLTE in LTE side, if existing concurrent data services simultaneously, UE initiates ModifyEPSbearercontextrequest (i.e. the request of amendment evolved packet system carrying content) flow process, core-network side can give the QCI of the newly-built speech business of user, retaining original QCI, core net issues the ERABModifiedRequest (the passage amendment request) QoS to UE at the S1 mouth being connected with base station and is updated afterwards simultaneously.
Therefore this programme mainly carrys out, with the QCI got, the service request that distinguishing terminal is different, on this basis, in another embodiment of the present invention, described step 20, including:
If the second service request processing described terminal being detected, obtaining the indication information judging congestion state, described indication information can be physical radio resource block utilization rate (i.e. PRB utilization rate), it is also possible to for real-time scheduling times;
The predetermined threshold value that described indication information is corresponding with described indication information is compared, and draws a comparative result;
If described comparative result shows that described indication information is more than or equal to described predetermined threshold value, then show that network is in congestion state.
Should be noted that, by obtaining the measuring amount in network, the real-time ruuning situation judging network, this kind of mode ensure that real-time and the accuracy of measurement, further, judge whether network is in what the step of congestion state was well known to those skilled in the art, be just no longer described in detail at this.
When judging that obtaining described network is in congestion state, if terminal is still being synchronously performed data service while carrying out voice call, the load that can make network strengthens, thus also affecting the quality of call, the described step 30 of the embodiment of the present invention is implemented as: hangs up at least one described second service request and/or reduces the scheduling times of at least one described second service request and the physical radio resource block dispatching number of distribution, then carrying out the process of the first service request.
Such as, when the data service that base station is just being cushioned at the wechat information updating of processing terminal A and video resource, now base station receives again the service request of the initiating speech conversation of terminal A, and now base station judges that the network (community B) obtaining terminal place is in congestion state, it is possible to take following scheme that data traffic resource assignment is adjusted:
Scheme one: since it is considered that the Internet resources of buffered video resource are relatively more, therefore in this programme, (namely stopping the buffering of video) is hung up in the data service cushioned by described video resource, reduces the time domain scheduling times (namely reducing the frequency of renewal) of the data service of wechat information updating simultaneously;
Scheme two: the data service of described wechat information updating and the buffering of video resource is all hung up;
Scheme three: hang up the data service of wechat information updating, reduces the number of resources (i.e. PRB number) of the data service distributing to video resource buffering simultaneously;
After the service request of voice call described in Chu Liwan, then recover wechat information updating and the data service of video resource buffering, namely give each data service distribution data resource by the data service state before voice call.
The simple of restriction data processing is simply illustrated by three above scheme, should be noted that, concrete in the application how the process of data service is controlled to carry out the formulation of scheme according to the demand of Virtual network operator and different strategies, just illustration no longer one by one in the present invention.
