Description
Technical field
The present invention relates to the treatment technology of user profile, be meant especially a kind of in WLAN (wireless local area network) the processing method to the subscriber terminal service annexation.
Background technology
Because the user is more and more higher to the requirement of wireless access rate, WLAN (wireless local area network) (WLAN, WirelessLocal Area Network) is arisen at the historic moment, and it can provide wireless data access at a high speed in more among a small circle.WLAN (wireless local area network) comprises multiple different technologies, and a widely used technical standard is IEEE802.11b at present, and it adopts the 2.4GHz frequency range, and another technology of using this frequency range is bluetooth (Bluetooth) technology.Other new technology such as IEEE 802.11a and ETSI BRAN Hiperlan2 use the 5GHz frequency range.
Although multiple different wireless access technology is arranged, most of WLAN is used for transmitting internet agreement (IP) packet data package.For a Wireless IP network, its concrete WLAN access technology that adopts generally is transparent for the IP on upper strata.Its basic structure all is to utilize access point (AP) to finish the wireless access of user terminal, connects to form the IP transmission network by network control and connection device.
Rise and development along with WLAN (wireless local area network) WLAN technology, WLAN and various wireless mobile communication network, such as: the intercommunication of GSM, code division multiple access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) (WCDMA) system, time division duplex-S-CDMA (TD-SCDMA) system, CDMA2000 system is just becoming the emphasis of current research.In third generation partner program (3GPP) standardization body, the network configuration that wlan system and the intercommunication of 3GPP system are simplified as shown in Figure 1.User terminal can link to each other with internet (Internet), Intranet (Intranet) by the access network of WLAN, can also be connected with 3GPP grouping of network territory via the WLAN access network.As seen, WLAN provides IP the wireless access technology of communication as a kind of, can be connected alternately with other multiple network.
WLAN is when being connected with other network, and work such as the authentication and authorization charging of connection generally can be provided with the application corresponding server and come control and treatment, such as: the authentication and authorization charging in the 3GPP system (AAA) server; User's information can be managed by information memory cell, such as: by home signature user server in the 3GPP system (HSS, Home subscriber server) or attaching position register (HLR) management.Therefore, when the needs authentication and authorization charging, information can be obtained and is stored in the server temporarily to the information memory cell request by the application corresponding server, when the user ends to serve, application server just can discharge stored user information, and so-called release is meant that application server can delete the related data of ending service-user, can be to delete its relevant data behind user's off-line immediately in the realization, also can keep deletion again behind the certain hour, so that the user utilizes when landing again.When changing in user's the information memory cell of information at its place, this memory cell in time notice application corresponding server refreshes data.
In actual applications, adhere to (attach) flow process to what the wlan network request inserted for the user, i.e. WLAN attach flow process, not corresponding mechanism is supported in the 3GPP technical specification.The wlan network that made access that WLAN user can't know that oneself is whether successful, the service that whether can use wlan network to provide, simultaneously, whether aaa server also can't clear and definite user can use the service based on WLAN.Equally, separation (detach) flow process of stopping using wlan network and from wlan network, separating for the user, it is WLAN detach flow process, also not corresponding mechanism is supported in 3GPP, therefore, make WLAN user can't know whether oneself successfully separates from wlan network, simultaneously, whether aaa server also can't clear and definite user can not re-use based on the service of WLAN.
In addition, need between application server and the information memory cell to carry out the synchronous of user profile, otherwise will cause unnecessary signaling waste.Such as: at present, when the user inserts or separate wlan network, user's service connection relation information only can be at service control unit, be the user profile application server,, can not notify user's information memory cell as upgrading in the aaa server, as HLR/HSS, so, because user information storage unit does not know which user profile service annexation changes, will cause the user data preserved in user's the information memory cell unreliable.In follow-up processing procedure, information memory cell also may provide user profile to the service control unit request, serve annexation, user data etc. as the user, thereby cause unnecessary signaling waste and meaningless occupying system resources, when this class signaling quantity is big, also may influence the normal operation of system.

Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Situation at present WLAN technology, the present invention proposes a kind of when the service annexation of WLAN user terminal changes in wlan network, each and user serve the connection relation information relevant portion, such as: service control unit, user information storage unit, the user is served the processing exchange method that annexation changes.Because user terminal is divided into two kinds with the service annexation of network: adhere to and separate, the present invention passes through WLAN user when inserting wlan network and separating wlan network, the service annexation that WLAN user serves annexation and service control unit changes, make user terminal and wlan network can both be clear and definite whether the user normally inserts, wlan network can be used the WLAN service; Perhaps user terminal separates from wlan network, needs to end the WLAN service.
The wlan system structure of realization exchange method of the present invention as shown in Figure 2, comprise: WLAN user terminal 201, WLAN access unit 202, service control unit 203 and user information storage unit 204, wherein, WLAN access unit 202, be responsible for the access and the routing management of user terminal, make user terminal wherein can pass through IP agreement mutual communication, and be connected with other IP network and communicate by letter, general main access point (AP) and the access controller (AC) of comprising in this WLAN access unit may comprise that also network connects the router of usefulness and associated server that network control is used or the like.Service control unit 203, be equivalent to the user control centre in the wlan system, whether mainly controlling the user by the mode of authentication can insert wlan network, and each user terminal in the network chargeed, this service control unit can be the user signing contract information applying unit, in actual applications, authentication and authorization charging (AAA) server is exactly an instantiation of service control unit.User information storage unit 204 is used for storing all users' information, can be realized by HSS/HLR.
The implementation procedure of the inventive method may further comprise the steps as shown in Figure 3:
The sign that expression user terminal and wlan network service annexation are adhered to or separated is set respectively in WLAN user terminal and service control unit in advance; This sign can be the specific identity that defines separately, or directly utilizes user terminal or the existing sign of service control unit.
A. when WLAN user terminal and wlan network connect, carry out attachment flow, the sign in success back user terminal and the service control unit is changed to WLAN respectively and adheres to.
B. when the WLAN user terminal separates with wlan network, can be connected with internetwork service, revise corresponding sign simultaneously by the mutual cancellation user terminal between WLAN user terminal and the wlan network; May there be interaction flow directly to revise service annexation sign yet, such as: wireless connections are interrupted, and when both sides can't connect, user terminal can directly be provided with the service annexation and be masked as the WLAN separation.
Wherein, cause terminal to be connected cancellation with the network service and not the reason of informing network also have terminal power down, WLAN card from computer, directly to be pulled out or crash or the like, the service annexation that network measuring also can be put this user after can't connecting terminal is masked as the WLAN separation.
Is example with aaa server as service control unit: when user terminal inserts wlan network, aaa server judges whether self exists this user's information, if do not have, then from user information storage unit, as downloading corresponding user data among the HSS/HLR and storing, after to the subscription authentication success, it is WLAN Attach that the current user of aaa server record serves annexation, give the user simultaneously and indicate accordingly, the user is at present attached in the wlan network in prompting; User terminal then identifies based on the service of WLAN with the change of corresponding service annexation or sign and can use.
The WLAN Attach flow process of user terminal as shown in Figure 4, in the present embodiment, HSS/HLR is as user information storage unit, this flow process comprises the steps:
Step 401: when the user need insert wlan network, set up user terminal earlier to the wireless connections between the wlan network, after connection has been set up, the WLAN user terminal sends the indication that request inserts wlan network via the WLAN access unit to aaa server, need show clearly in this indication that it is wlan network that the user asks the type of access network, and comprise this user's permanent or provisional sign.
After step 402:AAA server is received request, the request of judging earlier this user terminal inserts in the message whether provide effective user permanent or provisional sign, if no, then network needs initiatively to initiate effective sign that the inquiry flow process is obtained this user terminal; If have, then whether aaa server continues to judge self to have and currently sends the user profile of asking user terminal, if this user's data information not in the aaa server then enters step 403; Otherwise directly enter step 405.
Step 403～404:AAA server is asked the data message of this user terminal to corresponding HLR/HSS; HLR/HSS is inserted into the data message of this user terminal in the aaa server.
Step 405:WLAN network startup is to the authorizing procedure of current user terminal of WLAN.
Step 406: network is to after the current user terminal of WLAN authentication success, and aaa server writes down this user, and to serve annexation be WLAN attached, enters step 407; If authentication is unsuccessful, the then access request of aaa server refusing user's, process ends.
Step 407～408:AAA server sends the updating user data indication to HLR/HSS, upgrades the data message of current user terminal of WLAN; After HLR/HSS renewal user serves connection relation information, send the response message of updating user data to aaa server.This step also can be omitted, and frequently refreshes to avoid that the user among the HLR/HSS is served connection relation information.
Step 409:AAA server inserts response message to WLAN user's loopback, and the user is attached in the wlan network in prompting, and indication user wlan network can be used.After user terminal receives this message, need to change sign relevant on the terminal, sign WLAN service is available, as a WLAN service annexation sign is set, and enters state of activation at this moment.
WLAN detach flow process for user terminal can be divided into by its unpack format: explicit separation (Explicit WLAN detach) and implicit detach (Implicit WLAN detach); For ExplicitWLAN detach flow process, can be divided into again: initiate by the WLAN user terminal, or initiate by wlan network by its originating end.For the Explicit WLAN detach that initiates from user terminal, user terminal need indicate the reason of detach in the detach message that sends to wlan network; Equally, for the explicit WLAN detach that initiates from wlan network, network need indicate the reason of detach in the detach message that sends to the user.And Implicit WALN detach flow process is when being applied to the user and not getting in touch with wlan network for a long time, the detach flow process that network is initiated, and the detach flow process finishes the back network under this situation does not need to notify the terminal use.
This several detach situations are discussed respectively below:
When 1) initiating from wlan network Detach by the WLAN user terminal, this user terminal notice aaa server need finish the WLAN service, service control unit, and promptly aaa server upgrades the user to serve annexation accordingly is WLAN detach.As shown in Figure 5, this flow process may further comprise the steps:
When step 501:WLAN user terminal requests was separated from wlan network, the WLAN user terminal sent the detach notice to network, and the network type that comprises the separation of WLAN user terminal in the notice is the reason of wlan network and detach.
After step 502:AAA server received this notice, it was WLAN detach that the user who writes down this user terminal serves annexation.
Step 503:AAA server is to current user terminal of WLAN back response message, and this step is an optional step, and aaa server can separate from wlan network in order to the prompting user according to actual conditions to user terminal back response or non-back response.Such as: for the reason on the Operation and Maintenance, possible WLAN detach flow process only needs not need informing user terminal at aaa server and the mid-corresponding sign of HLR/HSS; Also have, aaa server detects not response and need to revise the service annexation for separating of user terminal, and just needn't send and be notified to user terminal this moment, the service annexation directly is set is masked as the WLAN separation and gets final product.
2) initiate WLAN detach flow process by wlan network.When wlan network for the reason on the network, wlan network may initiatively be initiated WLAN detach flow process to the user, this flow process can be initiated from aaa server or from HSS/HLR, be to initiate from aaa server in the present embodiment, the respective service annexation of aaa server renewal active user terminal is WLAN detach then.As shown in Figure 6, this flow process may further comprise the steps:
Step 601:WLAN network requests WLAN user terminal separates from wlan network, sends the detach notice by aaa server to the WLAN user terminal, and the network type that comprises WLAN user's separation in the notice is the reason of wlan network and detach.
Step 602: simultaneously the aaa server user that writes down this WLAN user terminal to serve annexation be WLAN detach.
Step 603: current user terminal of WLAN is to aaa server back response message, and this response message is used for showing that the user separates from wlan network, and this user ends based on the service of WLAN.This step is an optional step, and user terminal can be according to actual conditions to aaa server back response or non-back response.
3) implicit expression WLAN detach flow process.When the user does not get in touch with wlan network for a long time, the WLANdetach flow process is initiated by aaa server, the service annexation that aaa server upgrades WLAN user is WLAN detached, show that the user can not use the WLAN service, this moment, aaa server did not need to send any Indication message to the user.As shown in Figure 7, may further comprise the steps:
Step 701～702:AAA server initiatively initiate and the WLAN user terminal between after the getting in touch of certain number of times, if user terminal does not still have response, then the aaa server user that directly writes down this WLAN user terminal to serve annexation be WALN detach.Wherein, aaa server initiatively initiate and user terminal between the concrete number of times of getting in touch can preestablish according to actual conditions; Aaa server initiatively initiate and user terminal between the reason of getting in touch a lot: may be that the user does not get in touch with wlan network for a long time, corresponding timer set in the aaa server be overtime, causes aaa server to initiate attach procedure with user terminal; Also may be that other client's application request aaa server and user terminal are got in touch.
In above-mentioned explicit and implicit expression WLAN detach flow process, in order to guarantee the data sync between service control unit and the user information storage unit, service control unit has two kinds of processing modes to Detach: 1. recording user service annexation is WLAN Detach, and send user Detach to user information storage unit and notify, user information storage unit is put corresponding sign to this user's current service annexation; 2. user's service annexation sign is not set and directly with the deletion of this user profile, and sends user profile to user information storage unit and deleted notice, user information storage unit writes down this user at service control unit deleted marker.
So, 1. plant the service control unit of mode and the interaction process flow process between the user information storage unit based on, as shown in Figure 8, specifically may further comprise the steps:
Step 801～when the 802:AAA server is handled Detach, the active user of this user terminal serves annexation and is set to WLAN Detach sign, aaa server sends the Detach notice to HSS/HLR simultaneously, illustrates that this user separates from wlan network;
After step 803～804:HSS/HLR received this notice, also the active user of relative users terminal served annexation and is set to WLAN Detach sign, then, returns response message to aaa server, showed that the user serves annexation and correctly upgrades.
2. plant the service control unit of mode and the interaction process flow process between the user information storage unit based on, as shown in Figure 9, specifically may further comprise the steps:
Step 901～when the 902:AAA server is handled Detach, the user data of this user terminal of being stored in the deletion aaa server, aaa server sends user profile deletion notice to HSS/HLR simultaneously, illustrates that the data of this user terminal are deleted from aaa server;
After step 903～904:HSS/HLR receives this notice, write down the user data of corresponding WLAN user terminal and in aaa server, delete, then, return response message, show the deleted sign of user data is set to aaa server.
Above-mentioned adhere to or separating treatment in, also to set in advance the sign of expression WLAN user terminal and wlan network service annexation in the user information storage unit.
For the bearer messages of above-mentioned various exchange methods, can finish interactive operation by the special-purpose message of independent definition, such as: MAP (MAP) agreement or user's remote dial authentication service (RADIUS) agreement or DIAMETER agreement or the like; Also can finish interactive operation by in existing message, increasing parameter.User profile described in the such scheme can be user signing contract information.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
