Description

A kind of method that realizes user's route

Technical field

The present invention relates to mobile communication system, relate in particular to the method for a kind of user's of realization route in the architecture evolution of mobile communication system.

Background technology

Along with continuing to bring out of new technology, 3GPP (3rd Generation Partnership Project, third generation partner program) in future mobile communications neighborhood system architecture evolution, needs to consider lasting evolution and enhancing by from the wave point to the core network, so that in following 10 years, keep the technology first-strike advantage of 3GPP, for operator and the ever-increasing demand of user provide satisfied support at moving communicating field.Towards the evolution items (System Architecture Evolution, SAE is a System Architecture Evolution) of the packet domain core network of all-IP, rename now that EPS (Evolved Packet System, evolved packet system) starts just as under such background.The target of SAE is " formulate one have High Data Rate, low delays, packetization, support that multiple wireless access technology is the 3GPP system frame structure with portability of feature ".

The SAE network have support QoS (Quality of Service, service quality) end to end guarantee, comprehensively packetizing, support multi-access technology, increase support real time business, characteristics such as network layer flattening.The SAE network has further been realized separating of chain of command and user face data, newly-increased network element Mobility Management Entity MME (Mobility Management Entity) is as the network function body of accepting the chain of command user data, and MME has functions such as the roaming of support, authentication, bearer management.S6a interface between MME and the home signature user server HSS (Home Subscriber Server) referring to Figure 1A, provides the functions such as download of user data, authorization data.

Normal structure adopts Diameter through the clear and definite S6a interface in back is discussed at present, but needs MME to support simultaneously to realize intercommunication with the HSS of different operators different phase different editions.Type is mainly used in the HSS/HLR function of distinguishing the different phase different editions, has shown the protocol type of its support, has defined following several HSS type:

(1) Rel-8 version independence HLR (Home Location Register, attaching position register): only provide Gr+ interface based on MAP to Rel-8 version SGSN and Rel-8 version GGSN;

(2) preceding Rel-8 version HSS/HLR: only Rel-8 version SGSN and preceding Rel-8 version GGSN provide Gr interface based on MAP forward;

(3) Rel-8 version HSS: mainly point to MME S6a interface based on Diameter is provided.

According to above-mentioned definition to the HSS type, the interface protocol that the HSS of different editions supports is also inequality: as incumbent operator, and Rel-8 version HSS/HLR or Rel-8 version independence HLR before the HSS type of its operation is generally, only seating surface is to the interface protocol of MAP; For the newly deployed SAE network of operator, the HSS of Rel-8 version can seating surface to the interface protocol of Diameter; If but the roaming agreement of signing between operator is not supported Diameter, for example supports MAP, then MME can not realize the direct intercommunication with HSS under this kind scene.For this reason, normal structure has been introduced IWF IWF (Interworking Function) and has been used for the mapping between different network protocol, solve the mapping between Diameter and the MAP,, satisfy the demand of different operators so that realize MME and dissimilar HSS intercommunications.

MME realizes that by IWF and dissimilar HSS the scene of intercommunication is referring to Figure 1B.In Figure 1B:

IWF is towards Rel-8 version independence HLR or preceding Rel-8 version HSS/HLR, be similar to SGSN (Service GSN, Serving GPRS Support Node is the network element that core-network side is responsible for mobile management) function interface protocol based on MAP is provided, use the Gr/Gr+ interface; IWF is towards MME, and the function that IWF is similar to HSS provides the interface protocol based on Diameter, uses the S6a interface.IWF has finished inside the translation function between Diameter and the MAP, and described Diameter is the S6a interface protocol that is applied between MME and the HSS, and described MAP is the Gr/Gr+ interface protocol that is applied between MME and the HSS/HLR.If signed roaming agreement between operator based on signalling system No.7, then need to change mutually between MME and the Rel-8 version HSS through at least two IWF, the interface protocol based on MAP is provided between the IWF, use the Gr+ interface.

But normal structure does not have the deployment way of further clear and definite IWF, and the deployment way that is to say IWF does not have the routing mechanism of description messages simultaneously by operator oneself decision yet.Usually, the deployment way of IWF roughly can be divided into distributed deployment and centralized deployment dual mode:

So-called distributed deployment refers to that in the present invention IWF can lay respectively at the MME side and the HSS side is disposed, and IWF can independently dispose, and also can be integrated among MME or the HSS;

So-called centralized deployment refers to that in the present invention IWF carries out independent deployment, and is controlled by the third party.Further, no matter adopt which kind of deployment way, MME and HSS be simultaneously except the integrated IWF, and MME is when the opposite end sends a request message, and whether face needs message is delivered to the opposite end or directly is delivered to the selection of opposite end through IWF.Similarly, IWF is when the request message that receives from MME, and whether also face needs the message after the conversion is delivered to the opposite end or directly is delivered to the selection of opposite end, the problem that promptly described MME and IWF demand side are selected route through IWF.

In sum, the problem of prior art existence is:

How does MME select user's route? be whether MME needs through HSS under the IWF calling party; How does IWF select user's route? be IWF behind the request message that receives from MME, whether need the message HSS under IWF is delivered to the user once more after the conversion.
