Description
Technical field
The present invention relates to the cordless communication network technology, specifically, relate to a kind of bearing establishing method between different participant networks.
Background technology
Universal mobile telecommunications system (UMTS) is a kind of third generation cordless communication network technical standard of 3GPP (third generation partner plan) tissue definition, it is made up of core net, wireless access network and user equipment (UE) (UserEquipment), core net comprises circuit domain and packet domain, circuit domain provides based on Circuit-switched business (for example speech business), and packet domain provides the business based on packet switching (for example Internet visit).
Current, 3GPP organizes and studies the UMTS network next generation network of evolution (this network being called " evolvement network " herein) backward, and formulates the technical standard of evolvement network.Evolvement network will have a lot of new characteristics, and for example: the packet-type business only is provided, and real time business such as voice, visual telephone also will provide in the mode of grouping; Realize complete IP network, each node device is by I P network interconnection in the network, and each portable terminal adheres to distributing IP address, back; Better network topology structure is to improve the reliability of network.Evolvement network is made up of three parts: evolution wireless access network E-RAN (Evolved Radio AccessNetwork), evolution block core net EPC (Evolved Packet Core) and user equipment (UE).
Network service quality (QoS) is a key property of UMTS network end to end, and in future, will become a kind of main form of service of next generation mobile networks based on the teleservice of IP Multimedia System (IMS).Current QoS control of consulting based on IMS and negotiation mechanism are as shown in Figure 1.UE carries out service negotiation by the application layer signaling (IMS signaling) and the opposite end of network, negotiation result parses business information by Proxy Call Session Control Function (P-CSCF), by Gq interface business information is issued to strategic decision-making unit (PCRF or PDF) afterwards and finishes mapping from professional descriptor to IP QoS information.IP QoS information after the mapping is issued to strategy execution unit in the core net by Go interface.Core net is finished the mapping from the IP qos parameter of authorizing to the UMTS parameter of authorizing.Core net is according to network capabilities, and CAMEL-Subscription-Information carries out access control and carrying is set up, and initiates radio bearer to Access Network and assigns.Wireless network carries out the binding information that stream was set up and provided to UE to empty port load-supporting according to network capabilities.To set up good result at last reports to network.
Recently by network based ability and load state the notion that QoS carries out promotion and demotion is suggested, network can better be controlled QoS like this, more excellent QoS experience is provided and reduces the call denial probability to the user.But after the QoS promotion and demotion were introduced resource and set up flow process, when the path had experienced different networks end to end, the QoS between heterogeneous networks negotiation problem repeatedly highlighted.And existing QoS control and negotiation mechanism do not provide the QoS synchronization mechanism between heterogeneous networks.In addition, the process of setting up that flow process is serial is set up in present carrying, and it is then carrying out of one that the network carrying is set up, and this just is difficult to guarantee to carry the speed of foundation, and therefore the optimization that flow process is set up in carrying also is a major issue.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of bearing establishing method between different participant networks, by in operation flow end to end, the parallel loading establishing process that carries out different business participant network is to accelerate the process that carrying is set up.
To achieve these goals, technical scheme of the present invention is:
A kind of bearing establishing method between different participant networks comprises:
After professional participant carries out service negotiation by the application layer signaling, the information of carrying the QoS negotiation result is handed down to corresponding participant network;
Each participant network receives described QoS negotiation result, carries out access control concurrently and sets up with carrying.
Described method also comprises:
Response steps, described professional participant or professional participant network are circulated a notice of the QoS of corresponding participant network to the application layer network element.
Described method also comprises:
Comparison step, described application layer network element compares the QoS of each participant network.
If the QoS of each participant network equates or quite, then carrying is set up successfully;
If the QoS of each participant network is unequal or unsuitable, then described application layer network element redefines the QoS that sets up carrying according to the QoS of each participant network, and participant network with different QoS of notice and the QoS that redefines, with modification or rebulid carrying.
The QoS that described application layer network element redefines is minimum QoS among the QoS of each participant network; Described and QoS that redefine has the participant network of different QoS and revises or rebulid carrying according to the described QoS that redefines.
When the QoS of described each professional participant network foundation did not change with respect to the QoS that consults, then carrying was set up successfully.
Beneficial effect of the present invention is that the present invention has optimized the carrying in the teleservice and set up flow process, has effectively accelerated the speed that carrying is set up.When parallel foundation simultaneously of the present invention is carried QoS is carried out synchronous method, avoided the inconsistent problem of QoS between heterogeneous networks, promptly solved the stationary problem that carrying is set up between heterogeneous networks.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, specific embodiments of the invention are elaborated below in conjunction with accompanying drawing.
Core concept of the present invention is: after professional participant carries out service negotiation by the application layer signaling, negotiation result is handed down to each participant network, each participant network parallel independently carries foundation, thereby effectively accelerates the speed that carrying is set up.In addition, QoS may be changed at the network of certain or some participants, after each participant network QoS is consulted to finish respectively, the QoS result of each participant network can be compared at the application layer network element, select minimum QoS negotiation result, notify those results different professional participant networks, revise carrying and qos parameter, be consistent with minimum qos parameter.Like this, the present invention has just solved the synchronous problem of QoS that carrying is set up between the different participant network in teleservice.
Technical scheme of the present invention both had been applicable to that existing network also was applicable to evolvement network, and professional participant and professional participant network also be not limited only to two, and can be more than two.To be that example describes with two internetwork loading establishing process of different participant below.
Embodiment one
The flow chart that carrying is set up between the network when Figure 2 shows that an end-to-end path through two wireless networks.Carrying is set up flow process and is between the network when as shown in Figure 2, end-to-end path of the present invention is through two wireless networks:
1) participant carries out service negotiation by the IMS signaling
Terminal UE 1 is carried out the IMS registration and is carried out service negotiation (comprising that QoS consults) with the opposite end (terminal UE 2) of network by application layer signaling (as the IMS signaling) on the signaling bear of having set up.Because the registration of this step and negotiation flow process belong to prior art, do not give unnecessary details at this.
2) negotiation result is issued to each participant network
Negotiation result parses business information by P-CSCF, and by signaling business information is issued to each participant network (network 1 and network 2).
3) each participant network carries out access control and carrying foundation respectively
Network 1 and network 2 after obtaining the business information that IMS consults, parallel carrying of setting up respectively separately, thus effectively accelerate the speed that carrying is set up.The change of QoS might take place in certain or some networks in the participant network in the process that carrying is set up.Such as, if 1 couple of QoS of network carries out upgrade or downgrade and will cause QoS to change in the present embodiment.
4) each participant network of network (network 1, network 2) is to the QoS of the carrying of IMS network element circular foundation
Each participant network send carry the QoS that sets up carrying acknowledge message to the IMS network element, and proceed step 5).
5) judgement of QoS
The IMS network element can compare the QoS of each participant network circular, if equal or suitable, then carrying is set up successfully, directly enters step 8); If unequal or unsuitable, then enter step 6).
In this step 5), IMS also can only compare after judgement has the QoS of participant network to change again.For example, if the QoS and the step 2 of some (or a plurality of) participant network that IMS receives circular) be sent in the business information of participant network QoS not simultaneously, judge that then QoS changes, whether the QoS that the step of going forward side by side is carried out each participant network of comparison equates.Perhaps, whether IMS also can carry the indication information that indication QoS changes by judging in the described response message, if carry, then further relatively whether the QoS of each participant network is equal.
6) carry out the synchronous of QoS according to comparative result
Unequal or quite the time as the QoS of participant network, redefine the QoS of foundation carrying according to the QoS of each participant network by application layer network element (as IMS), preferably can select QoS conduct lower among the QoS of each participant network negotiation result again, and send carry this again the information of negotiation result to the higher network of QoS, carrying be revised or be rebulid to the higher network of the QoS that sets up should according to the QoS of the lower network of QoS, thereby realization QoS's is synchronous.Such as, when the QoS degradation takes place in loading establishing process network 1, and the QoS of network 2 is not when changing, the QoS that network 1 is set up is lower than the QoS that network 2 is set up, then carrying be revised or be rebulid to network 2 should according to the QoS of network 1, therefore by the IMS network element send carry lower QoS business information to network 2, carry out QoS with informing network 2 and revise or rebulid carrying.
Situation for a plurality of different participant networks, unequal or quite the time as the QoS of participant network, then can select QoS minimum among the QoS of each participant network as negotiation result, and notify those to have the participant network (the professional participant network that promptly has higher QoS) that is different from the QoS that redefines, revise carrying and qos parameter, be consistent with the negotiation result of the QoS that redefines (being minimum QoS).
7) revise or rebulid carrying
Carrying is revised or rebulid to network 2 according to the QoS information of carrying in the business information that receives.
8) the IMS Signalling exchange is finished, and carrying is set up, and can carry out business datum and transmit.
Embodiment 2
Fig. 3 is the flow chart that two network carryings of the embodiment of the invention 2 are set up.As shown in Figure 3, the main difference of itself and embodiment 1 is to be sent by application layer signaling (as the IMS signaling) by terminal UE the QoS information of foundation.Be that the response message that comprises QoS information in the step 4) passes to the IMS core cell by UE by the IMS signaling message, other step is identical with embodiment 1.
Fig. 2 and Fig. 3 only are illustrated method of the present invention at the situation of two different participant networks, but the present invention is not limited to this, and the present invention is equally applicable to the situation of a plurality of different participant networks.
The present invention proposes a kind of different participant network and set up the method for carrying fast, and when parallel foundation is carried, QoS is carried out synchronous method.When network can carry out upgrading processing to QoS, of the present inventionly QoS is carried out synchronous method seem particularly important.
Above specific embodiment only is used to illustrate the present invention, but not is used to limit the present invention.Within the spirit and principles in the present invention all, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
