Step 414, when Radio Resource is not enough or when not having Radio Resource available, described MME carries out resource optimization by different modes;
Particularly, described MME carries out resource optimization can be following two kinds of modes:
Mode one: carry out resource optimization when Radio Resource deficiency adopts QoS to adjust mode, particularly, as shown in Figure 5:
Step 501, when described base station judges now do not have resource available, sends initial background to described MME and sets up failed message;
Particularly, it is initialcontextsetupfailure that initial background sets up failed message, when carrying the reason of inadequate resource resourceinsufficiency in wherein said background setup failed message, described MME does not carry out the release of core-network side carrying at once.
Step 502, described MME, according to the type information of described UE, adopts QoS to adjust mode and carries out resource optimization;
Concrete, when the initial background receiving base station transmission sets up failed message, form QoS according to described type information and adjust mode, described QoS is adjusted mode and sends to described UE or the UE different from described UE, to adjust mode by the UE receiving described preset QoS adjustment mode according to preset QoS carrying out QoS adjustment; Or,
When the initial background receiving base station transmission sets up failed message, formed according to described type information and start QoS adjustment order, direct transmission described startup QoS adjusts order to described UE or the UE different from described UE, to carry out QoS adjustment by the UE receiving described startup QoS adjustment order.
Concrete QoS adjusts mode see the explanation in embodiment 1, repeats no more herein.
Step 503, described UE receives described QoS and adjusts order, and initiation QoS adjusts and carries out carrying QoS and changes;
Particularly, UE sends bearer resource to MME and requires amendment message, then, after MME receives bearer resource requirement amendment message, bearer resource order is sent, after P-GW receives bearer resource order by S-GW to P-GW, send to MME and upgrade Bearer Request, and send amendment request by MME to base station, after base station receives amendment request, initiate QoS adjustment to UE, after having revised, send more new support by MME to P-GW and respond.
Step 504, described MME again initiates background constructing, carries out radio bearer foundation after receiving the response message of the execution resource optimization that described UE sends.
Resource optimization is carried out when Radio Resource deficiency adopts QoS to adjust mode, obtain enough Radio Resources with this and carry out radio bearer foundation, with Radio Resource in prior art not enough or without available resources time, MME will carry out deleting load-bearing, to wait for after certain hour that UE again initiates PDN connection request and compares, the scheme that the embodiment of the present invention provides can be carried out QoS according to user type and type of service and be changed process, the enough Radio Resources obtained are carried out radio bearer foundation, meets the Radio Resource that user carries out data service.
Mode two: when setting up carrying resource requirement number and being greater than surplus resources number, according to described type information, carry out resource optimization according to preset mode; Wherein, described surplus resources number is when described base station detects that resource service condition exceedes predetermined threshold value, and described base station reports the current surplus resources number in the described base station of MME.Particularly, according to the type information of described UE, at least one mode adopting QoS to reduce in mode and the existing bearing mode of release carries out resource optimization.
It should be noted that, before employing mode two carries out resource optimization, need base station that a wireless resource utility efficiency threshold value is set, each user sets up after carrying completes, base station calculates now Radio Resource service condition and whether arrives threshold value, when wireless resource utility efficiency is greater than threshold value, report Radio Resource surplus resources to MME, so that described MME decision-making when carrying is set up uses.MME preserves after receiving the Radio Resource surplus resources reported.
It should be noted that, base station judges whether resource service condition exceedes predetermined threshold value, this threshold value is that operator is independently arranged according to demand, resources left situation is reported as operator can arrange base station when resource utilization reaches 70%, now can arrange predetermined threshold value is 70%, base station judges resource service condition, when resource service condition exceedes threshold value, by resources left resource reporting to MME, as now resource only remains 25%, be reported to MME now base station only remaining 25% resource can use, this resource situation reported also can comprise information more specifically, as the business support etc. of much speed can also be provided, so MME just can carry out Resourse Distribute according to the residue situation of Current resource.
When resource service condition exceedes predetermined threshold value, described Current resource surplus resources is reported described MME.
Scheme is particularly, the Radio Resource surplus resources of the described base station transmission that described MME inquiry is preserved, when judging this time to set up bearing resource deficiency, adopts service quality QoS to change and discharges at least one in existing carrying, again initiate background constructing, carry out radio bearer foundation.Wherein, the operation that QoS changes can be the operation done for current UE, also can be the operation carried out for other UE.Here, discharge the service connection set up and comprise the CN business or LIPA business that release connected.
Concrete QoS adjusts mode see the explanation in embodiment 1, repeats no more herein
When Radio Resource deficiency carries out allocation process according to Radio Resource situation, obtain Radio Resource with this and carry out radio bearer foundation, time not enough with Radio Resource in prior art, MME will carry out deleting load-bearing, to wait for after certain hour that UE again initiates PDN connection request and compares, the scheme that the embodiment of the present invention provides can process according to user type and type of service, and the Radio Resource of acquisition is carried out radio bearer foundation, solves and utilizes irrational problem to Radio Resource.
It should be noted that, in resource optimization process, the scheme that the invention process provides is by considering Non-Access Stratum factor, the user type of such as UE and type of service, Non-Access Stratum participates in the process of resource optimization, makes processing mode more flexible, in addition, in resource optimization process, there is the participation of UE, make UE to select processing mode, improve Consumer's Experience.
