Below in conjunction with accompanying drawing, the embodiment of the invention is elaborated.
The business features transmitted in the carrying of the embodiment of the invention according to non-GBR type definition bearing resource shared proportion in the AMBR limited range, thus reach the purpose of the business experience effect that improves the user effectively.Particularly, pre-configured AMBR service regeulations, service quality class indication (QCI comprising the non-GBR type, QoS Class Identifier) relative weighting coefficient, a plurality of EPS Bearer that one or more session is adopted, the distribution of carrying out bearing resource according to the AMBR service regeulations (need to prove, a session also has a plurality of EPS Bearer transmission, the video session process of being undertaken for example by video telephone, video transmits in a carrying, voice transmission in the another one carrying).Wherein, described relative weighting coefficient is to set according to the business statistics result of transmitting on the EPS Bearer of each non-GBR type.Referring to Fig. 1, a kind of resource allocation methods that the embodiment of the invention provides totally comprises step:
S101, PDN GW and eNB obtain the AMBR service regeulations, comprising the relative weighting coefficient of the QCI of non-GBR type.
Preferably, the embodiment of the invention is in advance at control rule of policy billing function (PCRF, Policy ﹠amp; Charging Rule Function) configuration AMBR service regeulations in the entity; The AMBR service regeulations that PDN GW obtains are that the PCRF entity sends to PDN GW; It is that PDNGW sends to eNB that eNB obtains the AMBR service regeulations.
Certainly, PDN GW and eNB also can obtain the AMBR service regeulations by other modes, for example, the AMBR service regeulations can be set in PDN GW and eNB separately, also can and send to PDN GW and eNB by other physical arrangements AMBR service regeulations.
S102, PDN GW and eNB carry out resource allocation according to the AMBR service regeulations to the carrying of the non-GBR type between UE and the PDN.
According to the definition of present AMBR, AMBR only is applicable to the carrying of the Non-GBR type that each UE is connected with each PDN.Based on this principle, preferably, as shown in Figure 2, in the embodiment of the invention, operator is tactful on the PCRF entity of operator's control according to operation, configuration AMBR QoS resource allocation default policy (being the AMBR service regeulations) in IP-CAN Bearer and IP-CAN session (Session) incidence relation form is comprising the relative weighting coefficient according to the QCI of each non-GBR type of Operator Specific Service statistical model definition.In addition, the AMBR service regeulations also can send to PDN GW and eNB by independent a piece of news, and do not need to be included in the incidence relation form of IP-CAN Bearer and IP-CAN Session.
Referring to Fig. 3, in the initial mutual process of PCRF entity and PDN GW, the PCRF entity is by the strategy and the control (PCC that charges, Policy Control and Charging) decision-making customization signaling, the AMBR service regeulations are disposed the GW to PDN, be that the PCRF entity sends strategy and charging control decision customization (PCC Decision Provision) message to PDN GW, wherein carry the incidence relation form of IP-CAN Bearer and IP-CANSession, include the AMBR service regeulations in this form, after PDN GW extraction and the preservation AMBR service regeulations wherein, return strategy and charging control decision customized responses (PCCDecision Provision ACK) message.And, set up at the default bearing of UE attaching process that PDN GW sends to eNB with the AMBR service regeulations in the process.
When the EPS system increases or deletes the carrying of a non-GBR type, when perhaps the carrying of certain non-GBR type does not have transfer of data within a certain period of time, the bearing resource that PDN GW adjusts the non-GBR type according to the AMBR service regeulations distributes, and the user data that makes UE send transmits on the bearing resource that is distributed.Therefore, only need between the initial setting stage or AMBR service regeulations when changing, up-to-date AMBR service regeulations be disposed to PDN GW and eNB, in follow-up AMBR adjustment process, can save a lot of signalings mutual between the network element at UE by this scheme.And,, help carrying out of Operator Specific Service by PCRF control AMBR service regeulations.
Referring to Fig. 4, the concrete grammar of a kind of resource allocation that the embodiment of the invention provides comprises step:
S401, PCRF physical arrangements AMBR service regeulations.
S402, first when mutual at PCRF entity and PDN GW, perhaps when the AMBR service regeulations changed, the PCRF entity disposed the GW to PDN with up-to-date AMBR service regeulations by PCC Decision Provision signaling.PDN GW sends to eNB by relevant signaling message with up-to-date AMBR service regeulations again.
S403, after the user sets up default bearing, PDN GW and eNB monitoring carrying situation of change, if when having bearing event newly-built or deletion non-GBR type to take place, then execution in step S404 promptly starts the AMBR adjustment process; Otherwise, execution in step S405.
S404, PDN GW and eNB adjust bearing resource according to the relation of the relative weighting between the QCI of appointment in the AMBR rule in the speed range that AMBR limited, set the maximum upper limit of each non-GBR carrying among the PDN GW.
S405, check not have data to transmit in the carrying whether have a non-GBR type of having set up, carrying for the non-GBR type that does not have data to transmit, start the timer (the EPS Bearer carrying for each non-GBR type of having set up in advance is provided with a timer in the embodiment of the invention) that is provided with for this carrying in advance, when timer expiry, if still there are not data to transmit in this carrying, execution in step S404 then, promptly PDN GW and eNB start the AMBR adjustment process.
Below step S402 is elaborated.
As shown in Figure 5, when during the UE network attachment, setting up default bearing (Default Bearer), MME sends to gateway (Serving GW) and sets up default bearing request (Create Default BearerRequest) message, Serving GW transmits Create Default Bearer Request message to PDN GW, then, PDN GW is notified to gateway Serving GW by creating default bearing response (Create Default Bearer Response) message with the AMBR service regeulations, Serving GW gives MME with this forwards, MME sets up request (Initial Context Setup Request) message by initial context these AMBR service regeulations is disposed to eNB, eNB receives and storage AMBR service regeulations, returns initial context foundation then and finishes (Initial Context Setup Complete) message to MME.
When the AMBR service regeulations that dispose in the PCRF entity took place to upgrade, the AMBR service regeulations after the PCRF entity will upgrade by PCCDecision Provision signaling sent to PDN GW; As shown in Figure 6, PDN GW is notified to Serving GW by the AMBR service regeulations of new bearer request (Update Bearer Request) after message will be upgraded more, Serving GW gives MME with this forwards, MME is notified to eNB by revising carrying request (Modify Bearer Request) AMBR service regeulations after message will be upgraded, eNB utilizes the up-to-date AMBR service regeulations that receive to upgrade the AMBR service regeulations of self storing, and returns modification carrying response (Modify Bearer Response) message and give MME; MME sends more, and new bearer responds (Update Bearer Response) message to Serving GW; Serving GW transmits Update Bearer Response message and gives PDN GW.
