The problem of uneven and customer service quality cannot be guaranteed.
2, it solves in centralized Joint admission control method, the response speed of call request is slow, processing delay is big, user's body
Test the problem of difference.
The present invention is applied to the multiple users (UE) in the case where Multi net voting covering and carries out new service request or switch to ask
In the acceptance judging asked, the Joint admission control method is specifically included:
1) in each network be arranged one enhancing local admission control entity, it is described local admission control entity according to
Thresholding is received to handle local call request according to the requested parameter of user terminal and current network, while the local connects
Controlled entity of receiving sends network state to Joint admission control entity and reports.
2) by the local admission control entity in Joint admission control entity centralized control all-network, Joint admission control
Entity receives the network state report from each local admission control entity, and the situation execution of comprehensive each network is united to receive control
System, while the Joint admission control entity, according to the state of each network, the local network for dynamically adjusting each network receives thresholding
Threshold value.
In the present embodiment, the local admission control entity be enhanced local admission control entity (eLAC,
Enhanced Local Admission Control).Method of the invention can be summarized are as follows: the eLAC of certain RAT collects local
The situation of network, to JAC(Joint admission control entity) it is reported.Meanwhile eLAC receives the control command from JAC, adjusts
It is whole oneself local network admission control parameter thresholding, efficiently locally realize Multi net voting resource joint optimization part function
Energy.JAC receives the network state report from each eLAC, and the situation of comprehensive each network executes united admission control.Meanwhile
For JAC according to the state of each network, the local network for dynamically adjusting each network receives the threshold value of parameter, more to reach combined optimization
Net resource and the purpose for ensureing user satisfaction.
In addition, the eLAC requests local call the foundation handled further include: the network of the user of user side connects
Enter ability and user preference, the load of the local network of network side and receiving strategy.
Therefore the local admission control entity of each RAT, according to the situation of the parameter of service request and current network,
Realize the admission control of the network internal.In order to efficiently carry out the united admission control of Multi net voting, controlled in original local receive
On the basis of system, enhanced.It is specifically included that in terms of enhancing
1) the local admission control mechanism enhanced, the information for comprehensively considering three aspects carry out admission control: a) net of UE
The user sides information such as network access capability, user preference；B) the network sides information such as the load of present networks, receiving strategy；C) it is controlled by JAC
The network of system receives the threshold value of threshold parameter.
2) resource situation of real-time statistics present networks is reported by the way of periodicity or event triggering to JAC.It is i.e. described
Local admission control entity sends network state report to Joint admission control entity by the way of periodicity or event triggering.
3) the control information from JAC is received, the parameter threshold level of local admission control mechanism is adjusted.
ELAC JAC control under processing business request, it is therefore an objective to enable those the service request locally received as soon as possible
It is handled, while can also take into account the resource optimization between Multi net voting.It is all sent at JAC compared to by all service requests
The centralized Joint admission control method of reason, eLAC improve the response speed of service request, especially considerably reduce those
The processing delay for the service request received by local network is still after JAC is adjudicated.For example, it is very light in local network load and
When the preference network of UE is present networks, it can directly be received by local network, be greatly improved the efficiency of admission control.
It is described local admission control entity the Joint admission control entity control under to local call request at
Reason, the Joint admission control entity is forwarded to if local network cannot be received and is handled, if local network can be received
Directly in local receiving.That is, enhanced local admission control entity eLAC requests local call under the control of JAC
It is handled.If present networks cannot receive, it is forwarded to JAC and is handled；Otherwise, directly in local receiving.In this way, can be most
Bigization plays the advantages of local admission control.
The Joint admission control entity is receiving the next service request of some local admission control entity forwarding
Afterwards, according to the situation of call request parameter and current each network, decide whether to receive the call request and ask the business
It asks and which network is accessed.Specifically, the Joint admission control entity comprehensively considers the negative of each network when carrying out admission control
The service request handled is assigned to the network of light load by load situation.
In the present embodiment, the situation of the comprehensive each network of Joint admission control entity JAC, carries out admission control；Root simultaneously
According to the situation of each network, the threshold parameter of each network eLAC is adjusted dynamically partially to realize Joint admission control.

Request is assigned to the network (in conjunction with other admission control schemes) of light load, avoids the serious uneven feelings of load between Multi net voting
Condition occurs.
On the other hand, JAC dynamically adjusts the load-threshold parameter in each eLAC according to the loading condition of each network, comes real
The now load balancing of each network.This mode can efficiently use the advantage of local acceptance controlling method rapidly and efficiently.JAC compares
The load of each network then adjusts the load-threshold parameter of each network if there is the serious unbalanced situation of each network load.It is right
In the network of load excessive, its load-threshold parameter is reduced；To the network of light load, its load-threshold parameter is improved.Processing
Process is as shown in Figure 2.
Step S11 is first carried out, collect each network load condition and judges respectively.Step S12 is executed later, is judged any
Whether network load overweight, i.e., RATi overload shown in figure? if so, executing step S13, the load door of RATi is reduced
Limit, if it is not, thening follow the steps S14, continues to determine whether any network load is overweight, i.e., RATi shown in figure was loaded
Gently? if so, thening follow the steps S15, the load-threshold of RATi is improved, if it is not, then terminating to adjust.
The eLAC of each network uses this load-threshold parameter for control by JAC, to judge that can local admission processing
Service request.When the load of local network is more than load-threshold, then new business is not received, and the service request is gone to
JAC processing；Otherwise, comprehensive other factors handle new service request.Treatment process is as shown in Figure 3.
Step S21 is first carried out, any local admission control entity eLACi receives service request.Step is executed later
S22 judges whether network present load is more than thresholding, which refers specifically to receive the eLACi of service request；If so, executing step
Rapid S23 cannot be received and is given to that JAC(is i.e. noted earlier to be forwarded to the combination admission control if local network cannot be received
Entity processed is handled), terminate entire treatment process after executing the step S23.If it is not, explanation is not above network present load
Thresholding thens follow the steps S24, makes decisions in conjunction with other parameters.It executes noted earlier if local network can be received
Directly in local receiving, the local admission control entity receives thresholding according to the requested parameter of user terminal and current network
Etc. information to local call request handle.
