Application Function is used to accept user's professional request for utilization, and to tactful network element (PF, PolicyFunction) issue business information and the professional required service quality (QoS that the user uses, Quality ofService) information, QoS information generally comprise the professional maximum bandwidth that connects, guarantee parameters such as bandwidth, time delay, shake, the error rate.Strategy NE is according to user's the CAMEL-Subscription-Information required QoS of this business that makes a strategic decision, and the QoS information through the business of decision-making that sends that the user using to user entity or mobile management entity.If strategy NE has been handed down to user entity with the QoS information of business, then user entity is issued mobile management entity with this information, in the process of setting up the user data carrying QoS information is passed to the base station by mobile management entity; If strategy NE has been handed down to mobile management entity with the QoS information of business, then mobile management entity passes to respectively base station and user entity with QoS information in the process of setting up the user data carrying.
When the user was attached to network, the communication that need set up from the subscriber equipment to the Application Function (AF, Application Function) in advance connected, and is used for the signaling message between transmission user equipment and the AF.When the user will commence business, (comprising provides the user various device of required business from the subscriber equipment to the packet data network need to set up one, for example: Internet server, streaming media server etc., exist communication to connect between these equipment and the AF) communication connect, this connects by way of Radio Access Network, radio core network to packet data network.Fig. 2 consults schematic flow sheet for QoS, and as shown in the figure, this establishment of connection process is as follows:
Step 201, user equipment (UE) needed earlier professional to Application Function AF application before setting up service connection.
After step 202, Application Function are accepted user's business application, can set up service connection between UE and the packet data network and resource and the QoS information that business is required sends to strategy NE PF to the strategy NE request.
Step 203, strategy NE can according to the user signing contract information that from the user-subscribed database of outside, obtains, when the subscriber equipment access network by the subscriber equipment access information of user equipment registration on PF and required resource and the QoS of the above-mentioned service connection of Necd decision of Application Function.
Step 204, strategy NE are to user entity MME or above-mentioned service connection is set up in mobile management entity UPE request and resource and the QoS information that service connection is required is handed down to user entity or mobile management entity.
Step 205, user entity or mobile management entity initiate to set up UE to the service connection of packet data network, and distribute the required resource of service connection that comprises QoS.
Step 206, user entity or mobile management entity distribute corresponding Radio Resource to the base station BS request, and provide required wireless resource information and the QoS information of eating dishes without rice or wine to the base station.
Step 207, the required Radio Resource of the professional connection of base station assigns.
Step 208, base station and subscriber equipment consultation business service are connected required Radio Resource.
After step 209, base station and subscriber equipment are consulted the distributing radio resource success, report the allocation of radio resources success to user entity or mobile management entity, and report the QoS information through consulting.
After step 210, service connection were set up and finished, user entity or mobile management entity connect to set up to the policy entity report to be finished, and reported the QoS information through consulting.
Step 211, policy entity report that to AF service connection is successfully established and reports the QoS information through consulting.
When if PF, MME/UPE, base station and UE find to satisfy professional QoS, can select refusal to set up professional the connection, and report AF.
Can be found out that by above-mentioned enforcement prior art exists because QoS negotiation mechanism imperfection causes professional foundation and Demolition Scheme simple, deficiency that can not practical requirement, such as:

In the enforcement, mobile core network QoS ability can be judged by MME or UPE.
PF is when judging whether the QoS ability can satisfy the professional required QoS of request connection, and PF can be according to one of user's CAMEL-Subscription-Information, user's access information, demand of service connection or its combination, decision-making, required resource and the QoS of the above-mentioned service connection of judgement.
This embodiment only is an embodiment, also has a variety of implementations in the enforcement, as: PF can determine to consult sign, step 303 also can be implemented before at " PF judges decision-making above-mentioned professional connect required resource and QoS ", that is,, can make a strategic decision by PF if AF does not determine to consult sign.To use each embodiment below further specifies.
Among the embodiment business is divided into permission and consults QoS and two classes that can not consult QoS.In the enforcement AF or PF when setting up service connection, request are consulted to identify to QoS.If AF can not determine whether consult QoS in the enforcement, PF also can determine whether to allow to consult QoS.If AF can determine whether to allow to consult QoS, PF also can handle QoS and consult sign.Mainly include but not limited to following content in the present embodiment:
1, when QoS consults to be designated " not allowing to consult ", if when BS, MME/UPE or PF find to satisfy required QoS, then should directly refuse service connection.
2, when QoS consults to be designated " allowing to consult ", if BS, MME/UPE or PF can not satisfy the QoS of request, then still continue to set up service connection, and set up the QoS information after the negotiation, i.e. BS, ME/UPE or PF acceptable QoS in the corresponding message at service connection.
3, when BS, MME/UPE or PF report refusal to set up service connection, the reason that can report simultaneously current network BS, MME/UPE and PF to allow the QoS information used and refusal to set up service connection.AF or PF can determine whether again initiating service connection according to new QoS according to the reason of the QoS information that reports and refusal service connection, perhaps will refuse the reason of service connection and notify to UE.
Further specify again below how implementation the present invention.
Embodiment one
The described AF of being of present embodiment sets up service connection to the PF request, and the QoS that identifies in request message is " not allowing to consult ", and PF is according to user's CAMEL-Subscription-Information and user's access information decision-making.When PF finds to satisfy the QoS demand of service connection, return the AF refusal and set up service connection, and report the QoS information of present negotiation to AF.
Fig. 4 is for being designated when not allowing to consult, and PF can not satisfy the implementing procedure schematic diagram under the professional QoS conditions of demand that connect, and as shown in the figure, comprises the steps:
Step 401, user equipment (UE) needed earlier professional to Application Function AF application before setting up service connection.
After step 402, Application Function AF accept user's business application, can set up service connection between UE and the packet data network and resource and the QoS information that business is required sends to strategy NE PF to the strategy NE request.The QoS that carries in request message consults to be designated " not allowing to consult ".
Step 403, tactful network element PF are according to one of user's CAMEL-Subscription-Information, user's access information, professional demand that connects or its combination, and above-mentioned professional connect required resource and QoS make a strategic decision.
Step 404, tactful NE Discovery can not satisfy sets up the professional required QoS that connects, and for example: the data bandwidth of professional connection request is 64kbps, but the bandwidth that the limit service in user's the subscription data connects is when being 16kbps.And check that QoS consults to be designated " not allowing to consult ", then need to report refusal to set up service connection to AF, and with the current QoS information that allows professional use, for example: bandwidth is 16kbps, and the reason that PF refusal is set up service connection sends to AF, as: signatory QoS can not satisfy professional requirement.
The professional QoS information of using of permission that AF reports according to PF sets up the reason of service connection with refusal and the QoS of business need determines whether again service connection is set up in request.If the professional reduction QoS that allows, for example: the professional minimum bandwidth that allows to use is 16kbps, and this moment, voice quality descended, and the QoS of reduction is lower than or equals the QoS that PF reports, then AF can ask to set up service connection again, and service connection uses the QoS that reduces.In addition, AF also can record the QoS information of this user terminal that reports, after being convenient to as the reference of the QoS of service connection.
Embodiment two
Present embodiment is described to be to be designated when not allowing to consult, and AF sets up service connection to the PF request.PF decision-making allows service connection to set up, and sets up professional connection to MME or UPE request, and MME or UPE can not satisfy and set up the required QoS of service connection, and then refusal is set up service connection, and reports the QoS information of negotiation to AF by PF.
Fig. 5 is being for being designated when not allowing to consult, and MME or UPE can not satisfy the implementing procedure schematic diagram under the QoS conditions of demand of service connection, as shown in the figure, comprise the steps:
Step 501, user equipment (UE) are before setting up service connection, and be earlier professional to Application Function AF application.
After step 502, Application Function AF accept user's business application, set up service connection between UE and the packet data network and resource and the QoS information that business is required sends to strategy NE PF to the strategy NE request.
Step 503, tactful network element PF are according to one of user's CAMEL-Subscription-Information, user's access information, professional demand that connects or its combination, and above-mentioned professional connect required resource and QoS make a strategic decision.The strategy network element is made a strategic decision, and current resource can be set up professional connection and satisfied business connects required QoS, and this QoS does not allow to consult.
Step 504, strategy NE are set up service connection to MME or UPE request, and the QoS information that business is required is handed down to MME or UPE.The QoS that carries in request message consults to be designated " not allowing to consult ".
Whether step 505, MME or UPE can satisfy the required QoS of service connection according to setting up the service connection request inspection.
Step 506, MME or UPE discovery local resource or pre-configured local policy can not satisfy sets up the required QoS of service connection, for example: the data bandwidth that service connection requires is 64kbps, but the service connection bandwidth that local resource or pre-configured local policy allow is 16kbps etc., and check that QoS consults to be designated " not allowing to consult ", then need to report refusal to set up service connection to PF, and with the current QoS information that allows professional use, for example: bandwidth is 16kbps, reason with the refusal service connection, as: bandwidth can not satisfy professional requirement, sends to PF.
The reason that step 507, PF will refuse the report of service connection, the professional QoS information of using of current permission and refusal service connection sends to AF.
The reason of the professional QoS information of using of permission that AF reports according to PF, the QoS of business need and refusal service connection determines whether again service connection is set up in request.If professional allow to reduce QoS, and the QoS that reduces is lower than or equals the QoS that PF reports, and then AF can ask to set up service connection again, and service connection uses the QoS that reduces.In addition, AF also can record the QoS information of this user terminal that reports, after being convenient to as the reference of the QoS of service connection.
Embodiment three
Present embodiment is described similar with embodiment one and embodiment two, is designated not allow to consult, and difference is that the professional network element that connects of refusal is BS or UE.These two network elements will carry the QoS information that allows access equally in the professional report that connects of refusal, i.e. QoS information of Xie Shanging.
Fig. 6 is being for being designated when not allowing to consult, and BS or UE can not satisfy the implementing procedure schematic diagram under the QoS conditions of demand of service connection, as shown in the figure, comprise the steps:
Step 601, user equipment (UE) are before setting up service connection, and be professional to Application Function AF application.
After step 602, Application Function AF accept user's business application, can set up service connection between UE and the packet data network and resource and the QoS information that business is required sends to strategy NE PF to the strategy NE request, carry QoS and consult sign in request message, sign content is " not allowing QoS to consult ".
Step 603, tactful network element PF are according to one of user's CAMEL-Subscription-Information, user's access information, professional demand that connects or its combination, and above-mentioned professional connect required resource and QoS make a strategic decision.The current resource of strategy NE decision-making can be set up service connection and satisfy the required QoS of service connection.
Step 604, strategy NE are set up service connection to MME or UPE request, and the QoS information that business is required is handed down to MME or UPE, carry QoS and consult sign in request message.
Step 605, MME or UPE set up service connection according to request, and check whether to satisfy the required QoS of service connection
Step 606, MME or UPE think can satisfy the required QoS of service connection, therefore sets up distributing radio resource to the BS request, and issues QoS information, carries QoS and consult sign in request message.
Step 607, BS check whether current Radio Resource can satisfy the Radio Resource of request.
Step 608, BS and UE consult to distribute idle wireless resource.
If BS checks and finds that the current wireless resource can not satisfy the Radio Resource of request in the step 607, BS can directly refuse, and then this step can be omitted.
Step 609, the current wireless resource of BS finding in the process of checking or consulting can not satisfy sets up the professional required QoS that connects, for example: the data bandwidth of professional connection request is 64kbps, but when the bandwidth that the Radio Resource deficiency can only limit service connects is 16kbps, and check that QoS consults to be designated " not allowing to consult ", then BS need report the Radio Resource deficiency to MME or UPE, and will have the information that Radio Resource allows the QoS that uses now, for example: bandwidth is 16kbps, and refusal assigned radio resource reason, as: idle wireless resource deficiency or bandwidth deficiency etc. send to MME or UPE.
Step 610, MME or UPE report the foundation of PF refusal service connection, and will allow the information of the QoS of use to report PF with the reason that refusal connects.
Step 611, PF will refuse the report of service connection, the QoS information of permission use and the reason that refusal is set up service connection and send to AF.
The reason that the QoS information that AF reports according to PF, the QoS of business need and refusal are set up service connection determines whether again service connection is set up in request.If professional allow to reduce QoS, and the QoS that reduces is lower than or equals the QoS that PF reports, and then AF can ask to set up service connection again, and service connection uses the QoS that reduces.In addition, AF also can record the QoS information of this user terminal that reports, after being convenient to as the reference of the QoS of service connection.
Embodiment four
The described AF of being of present embodiment is when service connection is set up in request, the QoS that carries in request message consults to be designated " allowing to consult ", PF, MME/UPE, BS and UE can set up earlier service connection, and giving AF with the QoS information reporting of consulting, AF adjusts business accordingly according to the QoS that reports.
Fig. 7 is for when being designated the permission negotiation, and the implementing procedure schematic diagram of PF, MME/UPE, BS and UE as shown in the figure, comprises the steps:
Step 701, user equipment (UE) are before setting up service connection, and be professional to Application Function AF application.
After step 702, Application Function AF accept user's business application, set up service connection between UE and the packet data network and resource and the QoS information that business is required sends to strategy NE PF to the strategy NE request, carry QoS and consult sign in request message, sign content is " allowing QoS to consult ".
Step 703, tactful network element PF are according to one of user's CAMEL-Subscription-Information, user's access information, professional demand that connects or its combination, and above-mentioned professional connect required resource and QoS make a strategic decision.Whether the current resource of strategy NE decision-making can satisfy the required QoS of service connection, if can not satisfy, and checks when QoS consults to be designated " allowing to consult " QoS that the current resource of then making a strategic decision out can satisfy, the QoS that namely consults.
Step 704, strategy NE are set up service connection to MME or UPE request, and the QoS information of the QoS that business is required or negotiation is handed down to MME or UPE, carry to allow QoS to consult sign in request message.
Step 705, MME or UPE set up service connection according to request, and check whether to satisfy the required QoS of service connection.If can not satisfy, and allow to consult QoS, then negotiate suitable QoS according to existing resource.
Step 706, MME or UPE set up distributing radio resource to the BS request, and issue the QoS information of QoS or negotiation, carry to have allowed QoS to consult sign in request message.
Step 707, BS check whether current Radio Resource can satisfy the Radio Resource of request.
Step 708, BS and UE consult to distribute idle wireless resource.
The current wireless resource of step 709, BS finding in the process of checking or consulting can not satisfy sets up the professional required QoS that connects, for example: the data bandwidth of professional connection request is 64kbps, but when the bandwidth that the Radio Resource deficiency can only limit service connects is 16kbps, and check that QoS consults to be designated " allowing to consult ", then BS need report the distributing radio resource response to MME or UPE, and with the information of the QoS that consults, for example: bandwidth is 16kbps, sends to MME or UPE.
Step 710, MME or UPE report the professional establishment of connection response of PF, and the information of the QoS that consults is reported PF.
Step 711, PF send to AF with the QoS information of professional connection establishment response and negotiation.
AF adjusts professional QoS according to the QoS information that the service connection that reports is set up response and negotiation.
In concrete enforcement, can also implement in the following manner:
One, QoS consults to identify and can be issued according to the needs of business by AF in embodiment two and embodiment three, also can be issued according to the needs of QoS of survice strategic decision-making by PF.Simultaneously PF can revise the QoS that AF issues according to the needs of the strategic decision-making of business and consult sign.
Two, in embodiment one to embodiment three, if the sign that does not have QoS to consult, and Internet resources can not satisfy the professional qos requirement that connects, and whether each network element can break off relations with the default mode decision is set up professional the connection, and each network element comprises PF, MME/UPE, BS and UE.Each network element can carry in the professional report that connects of refusal foundation and allow the QoS information of using and/or refuse to set up the professional reason that connects, wherein, reason can be the demand that Internet resources can not satisfy QoS of survice, can be specific to which parameter or which parameter that can not satisfy among the QoS.These parameters can comprise maximum bandwidth, guarantee bandwidth, size of the data type of average bandwidth, peak bandwidth, transmission, time delay, shake, packet, priority, the bit error rate etc.; Reason For Denial also can be that service connection is set up in the signatory restriction of customer service or user place regional limits is set up service connection; Reason For Denial can also comprise it being which network element refusal is set up service connection in addition.
Three, in embodiment one to embodiment four, if there is QoS to consult sign, and Internet resources be can not satisfy the qos requirement of service connection the time, and each network element can determine according to the indication of this sign simple accept or refusal be set up service connection.In refusal is set up the report of service connection, also can only carry and allow the QoS information of using or only carry refusal and set up the reason of service connection, even neither carry.
Four, in embodiment one to embodiment three, AF can set up the QoS information of the permission use of carrying in the report of service connection and/or the reason that refusal is set up service connection according to refusal, determines whether to revise professional QoS and again initiates service connection.For example:
(1) if that to be the user signatory is limited or the region is limited for Reason For Denial, then do not need to rebulid professional the connection.
(2) if PF or MME/UPE are because the not enough refusal of Internet resources is set up service connection, and the QoS that Internet resources can satisfy is greater than or equal to professional required minimum or lower QoS, and then AF can ask to set up service connection again with the required minimum or lower QoS of business.
(3) if BS or UE set up service connection because of the not enough refusal of idle wireless resource, and the QoS that idle wireless resource can satisfy is much larger than the required minimum or lower QoS of business.Then AF can use professional required minimum or lower QoS to ask to set up professional the connection once more.
Five, in embodiment three, if base station or UE do not support to discern QoS and consult sign, whether then no matter QoS consults sign allows to consult QoS, the base station can be distributed the radio open resource voluntarily, perhaps base station and UE consult distributing radio resource, and the radio open resource information reported MME/UPE, MME/UPE can compare according to radio open resource of having distributed that reports and QoS, if the radio open resource of distributing can not satisfy the requirement of QoS, and QoS consults to be designated " not allowing to consult QoS ", then MME/UPE can refuse to set up professional the connection, and informing base station discharges the idle wireless resource information of having distributed.
Six, in embodiment two to embodiment four, MME/UPE and PF all can revise or the QoS information of the directly negotiation in the transparent transmission service connection establishment response or the report of refusal service connection in the reason that connects of entrained QoS information and refusal.
The embodiment of the invention also provides a kind of quality of service negoriation system of wireless communication networks, describes below in conjunction with the embodiment of accompanying drawing to negotiating system.
Fig. 8 is a quality of service negoriation system configuration schematic diagram, as shown in the figure, comprise in the negotiating system: subscriber equipment, base station, mobile core network, Application Function, tactful network element, identification module, professional link block, the work relationship of each modular unit is as follows in the system:
