Description
Technical field
The present invention relates to a kind of QoS business manner of execution, specifically, relate to a kind of QoS business manner of execution under multi-network cooperative.
Background technology
PCC (Policy and Charging Control, policy and charging control) framework is QoS (the Quality of Service of core net evolution SAE of future generation (System Architecture Evolution) project, quality of service) security mechanism, it is characterized in that take Business Stream as granularity, highly mechanism the End-to-end QoS scheme, wherein, can be so that network detect different Business Streams by this framework, and realize that QoS controls, the demands such as charging meter for Business Stream.
Fig. 1 is the schematic diagram of PCC group-network construction in prior art;
as shown in Figure 1, shown in the PCC framework, comprise following functional entity: AF (Application Function, Application Function), PCRF (Policy and Charging Rule Fuction, strategy and charging control unit), PCEF (Policy and Charging Enforcement Function, strategy and charging performance element), BBERF (Bearing Binding and Event Report Function, bearing binding and event reporting function entity), SPR (Subscription Profile Repository, the user property memory), OCS (Online Charging System, Online Charging System) and OFCS (Offline Charging System, off-line accounting system).
Wherein, PCRF is the centralized decision-making point of QoS rule, the input of its decision-making derives from the user signing contract information that comprises in business information (ID of Business Stream description, Business Stream bandwidth demand, Business Stream medium type, business), user ID and the SPR that the Rx interface of AF provides, the carrier policy of local configuration, PCRF generates and authorizes the QoS backward PCEE of rule or BBERF, and carries out strategy execution by PCEE or BBERF according to mandate QoS rule.
PCC framework and Access Network are irrelevant, and wherein, under the 3GPP network, PCRF generates and authorizes the backward PCEF of QoS rule to issue, and carries out strategy execution by PCEF according to mandate QoS rule; Under non-3GPP network (as WLAN, Wimax), PCRF generates and authorizes the backward BBERF of QoS rule to issue, and carries out strategy execution by BBERF according to mandate QoS rule.
Wherein, the QoS rule mainly comprises 2 partial contents: the description of Business Stream and relevant qos parameter.Described qos parameter mainly comprises ARP, QCI and bandwidth demand:
Wherein ARP is generally used for embodying user's grade (as gold, silver and bronze) and the grade of Business Stream, and specifically, the effect of ARP is summarized as follows:
1. be used for loading establishing process, determine the priority that resource is distributed, the carrying that priority is high can preferentially obtain resource.
2. after being used for carrying foundation, in resource-constrained situation, determining the carrying preempting resources, and resist the ability that resource is preempted.
Usually, ARP is comprised of three parts:
Priority level (priority level): value is 1～15,1 to be peak.Be used for determining whether the foundation of carrying or the request of modification can be received, especially in resource-constrained, the request that the carrying that priority is high is set up or revised is paid the utmost attention to
Pre-emption capability (seizing ability): value is yes or no.The carrying that is used for high priority represents whether to have the ability of the resource of the carrying of seizing low priority.Usually operator is yes with this field value.
Pre-emption vulnerability (being preempted defensive ability/resistance ability): value is yes or no.The carrying whether carrying that is used for low priority represents to allow to be had the high priority of the ability of seizing is seized.Usually operator is no with this field value.
QCI has characterized the quality requirements such as the forwarding priority of Business Stream in transmitting procedure, packet loss, the error rate.
Fig. 2 is the system architecture of network evolution during to LTE.Wherein PDN Gateway is the PCEF that realizes in the PCC framework.
Wherein, under the LTE network, each Business Stream finally transmits in a carrying with specific QoS parameter.
In addition, PCEF carries out when the QoS rule that execution Gx interface issues in such a way:
If be present in the carrying of the qos parameter (referring to ARP, QCI) that Gx request is complementary, the Business Stream that adds in the TFT of this carrying in the Gx request is described, and transmits in the carrying of the qos requirement that requires to realize this Business Stream; In case of necessity, revise the parameters such as MBR/GBR of this carrying.
If there is not satisfactory carrying, the qos parameter according to the Gx request requires a newly-built carrying, and the Business Stream that adds in the TFT of this carrying in the Gx request is described;
Be directed in the situation of newly-built carrying, set up in request in carrying and carried the ARP parameter, concrete transmission path as shown in Figure 3 under pure LTE network, wherein, when interface-free resources is not enough, the ARP parameter of the existing carrying of eNB basis and the ARP parameter in the Gx request are torn chain open to the carrying of low priority, discharge interface-free resources and meet the carrying of the high priority of Gx interface requests requirement with foundation.
But prior art has following technical disadvantages:
Under present PCC framework, ARP can only embody the priority under the present wireless network type of living in of terminal (as 3G, LTE), and the value according to ARP when resource is nervous simply discharges the carrying of low priority;
In addition, merely based on the resource allocation proposal of ARP only single consideration the terminal wireless network of access at present, and 3 kinds of networks can't be done as a wholely to provide service to the user, and this network satisfaction degree for the raising user is highly profitable.
For example, (user gradation is that gold medal, the service of carrying out business a-this business can normally be used under 2G, 3G and LTE to have accessed user A under a LTE base station, the ARP grade is for high) and B (user gradation be bronze medal, the service of carrying out business b-this business can only LTE under normally use, the ARP grade is low), current network resources is nervous, (grade is silver medal to user C, during the ARP grade is), based on present technology, PCEF can discharge the carrying of user B, sets up carrying to serve user C.The satisfaction that can cause in this case user B descends.
