Technical field
A kind of a kind of the present invention relates to qos business executes method, it particularly relates to qos business under multi-network cooperative
Execution method.
Background technology
Pcc (policy and charging control, policy and charging control) framework is core net evolution of future generation
The qos (quality of service, quality of service) of sae (system architecture evolution) project ensures
Mechanism, is characterized in that with Business Stream as granularity, the qos scheme end to end of height mechanism, wherein, by this framework so that
Network detects different Business Streams, and realizes qos control, the demand 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 pcc framework, including following functional entity: af, (application function, should
With functional entity), 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, user property memorizer), 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, and the input of its decision-making derives from the business that the rx interface of af provides
The use comprising in information (business stream description, Business Stream bandwidth demand, Business Stream medium type, the id of business), user id and spr
Family CAMEL-Subscription-Information, locally configured carrier policy, pcrf generates and authorizes backward pcee or bberf of qos rule, and by pcee
Or bberf carries out strategy execution according to mandate qos rule.
Pcc framework is unrelated with access network, and wherein, under 3gpp network, pcrf generates and authorizes under the backward pcef of qos rule
Send out, and strategy execution is carried out according to mandate qos rule by pcef；Under non-3gpp network (as wlan, wimax), pcrf generates
Authorize the backward bberf of qos rule to issue, and strategy execution is carried out according to mandate qos rule by bberf.
Wherein, qos rule is main includes 2 partial contents: the qos parameter of the description of Business Stream and correlation.Described qos parameter
Main arp, qci and the bandwidth demand of including:
Wherein arp is generally used for embodying the grade (as gold, silver and bronze) of user and the grade of Business Stream, specifically, arp's
Effect is summarized as follows:
1. it is used in loading establishing process, determining the priority of resource allocation, the high carrying of priority can preferentially be provided
Source.
2. after being used for carrying and setting up, resource-constrained in the case of, determine to carry preempting resources, and resist resource and be preempted
Ability.
Usually, arp is made up of three parts:
Priority level (priority level): value is peak for 1～15,1.For determining the foundation carrying or repairing
Whether the request changing can be received, and especially when resource-constrained, what priority was high carries the request set up or change
It is prioritized
Pre-emption capability (seizes ability): value is yes or no.Carrying for high priority represents
Whether there is the ability of the resource of the carrying seizing low priority.Generally this field value is yes by operator.
Pre-emption vulnerability (is preempted defensive ability/resistance ability): value is yes or no.For low priority
Carrying indicate whether to allow the carrying of high priority with the ability of seizing to seize.This field value is by generally operator
no.
Qci characterizes the prescriptions such as forwarding priority in transmitting procedure for the Business Stream, packet loss, the bit error rate.
Fig. 2 is e-learning quality to system architecture during lte.Wherein pdn gateway is to realize in pcc framework
pcef.
Wherein, under lte network, each Business Stream finally transmits in a carrying with specific qos parameter.
Additionally, pcef, when executing the qos rule that gx interface issues, is carried out in such a way:
If being present in the carrying of the qos parameter (referring to arp, qci) that gx request matches, add in the tft of this carrying
Plus the business stream description in gx request, transmitted in the carrying that the qos requiring requires with realizing this Business Stream；If necessary, change
The parameters such as the mbr/gbr of this carrying.
If there is not satisfactory carrying, according to the newly-built carrying of the qos parameter request of gx request, and hold at this
Add the business stream description in gx request in the tft carrying；
In the case of being directed to newly-built carrying, carry arp parameter carrying to set up in request, have under pure lte network
As shown in figure 3, wherein, when interface-free resources are not enough, enb asks the transmission path of body according to the arp parameter having carried and gx
In arp parameter the carrying of low priority is carried out tearing open with chain, release interface-free resources are to set up the height meeting the requirement of gx interface requests
The carrying of priority.
But, prior art has following technical disadvantages:
Under current pcc framework, it is preferential under residing wireless network type (as 3g, lte) at present that arp can only embody terminal
Level, when resource is nervous, the carrying of low priority is simply discharged by the value according to arp；
Additionally, being based purely on, the resource allocation proposal of arp is only single to consider the wireless network that terminal accesses at present,
And 3 kinds of networks cannot be provided a user with service as an entirety, and this is for the network satisfaction degree improving user very
Beneficial.
For example, (user gradation is gold medal, carries out service-this industry of business a to have accessed user a under a lte base station
Business normally can use under 2g, 3g and lte, and arp grade is height) and b (user gradation is bronze medal, carries out the clothes of business b
Business-this business normally can only use under lte, and arp grade is low), current network resources are nervous, and (grade is silver medal to user c, arp
During grade is), based on current technology, the carrying of user b can be discharged, set up and carry to serve user c by pcef.This feelings
The satisfaction that user b can be caused under condition declines.
