Description

A kind of service log-on method that inserts based on IP

Technical field

The present invention relates to the service log-on technology, refer to a kind of service log-on method that inserts based on IP especially.

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, a widely used technical standard is IEEE802.11b at present, it adopts the 2.4GHz frequency range, the maximum data transmission rate can reach 11Mbps, use the IEEE802.11g and bluetooth (Bluetooth) technology in addition of this frequency range, wherein, 802.11g the maximum data transmission rate can reach 54Mbps.Other new technology such as IEEE802.11a and ETSI BRAN Hiperlan2 use the 5GHz frequency range, and maximum transmission rate also can reach 54Mbps.

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 the 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, user terminal can link to each other with internet (Internet), Intranet (Intranet) by the access network of WLAN, can also be connected with the home network of 3GPP system or the accesses network of 3GPP system via the WLAN access network, specifically be exactly, when the WLAN user terminal inserts in this locality, link to each other with the home network of 3GPP via the WLAN access network, as shown in Figure 2; When roaming, link to each other with the accesses network of 3GPP via the WLAN access network, part entity in the 3GPP accesses network respectively with the 3GPP home network in corresponding entity interconnection, such as 3GPP authentication and authorization charging (AAA) agency in the 3GPP accesses network and 3GPP authentication and authorization charging (AAA) server in the 3GPP home network; WLAN (wireless local area network) in the 3GPP accesses network inserts packet data gateway (PDG, Packet DataGateway) in critical point (WAG) and the 3GPP home network or the like, as shown in Figure 1.Wherein, Fig. 1, Fig. 2 are respectively under the roaming condition and the networking structure schematic diagram of wlan system and the intercommunication of 3GPP system under the non-roaming situation.

Referring to Fig. 1, shown in Figure 2, in the 3GPP system, mainly comprise home signature user server (HSS)/attaching position register (HLR), 3GPP aaa server, 3GPP AAA agency, WAG, packet data gateway, charging critical point (CGw)/charging information collecting system (CCF) and Online Charging System (OCS).All entities of user terminal, WLAN access network and 3GPP system have constituted the 3GPP-WLAN Internet jointly, and this 3GPP-WLAN Internet can be used as a kind of LAN service system.Wherein, the 3GPP aaa server is responsible for authentication, mandate and the charging to the user, and the charging information collecting that the WLAN access network is sent here also sends charge system to; Packet data gateway is responsible for the transfer of data from the WLAN access network to 3GPP network or other packet networks with user data; Charge system mainly receives and writes down the customer charging information that network transmits, and comprises that also OCS transmits online cost information according to online charging user's expense situation indication network is periodic, and adds up and control.

Under non-roaming situation, when the WLAN user terminal wishes directly to insert Internet/Intranet, after user terminal was finished the access authentication mandate by WLAN Access Network and aaa server (AS), user terminal can be linked into Internet/Intranet by the WLAN Access Network.If the WLAN user terminal also wishes to insert 3GPP packet switching (PS) territory business, then can be further to the business of 3GPP home network application intercommunication scene 3 (Scenario3), that is: the WLAN user terminal is initiated the service authorization request of intercommunication scene 3 to the AS of 3GPP home network, the AS of 3GPP home network carries out service authentication and mandate to this service authorization request, if success, then AS sends access grant message to user terminal, and AS distributes corresponding PDG to user terminal, after setting up the tunnel between user terminal and the PDG that distributed, can insert 3GPPPS territory business.Simultaneously, CGw/CCF and OCS are according to the network operating position recording gauge charge information of user terminal.Under roaming condition, when the WLAN user terminal wished directly to insert Internet/Intranet, user terminal can be linked into Internet/Intranet to the application of 3GPP home network by the 3GPP accesses network.If user terminal also wishes to apply for intercommunication scene 3 business, be linked into 3GPP PS territory business, then user terminal need be initiated the service authorization process to the 3GPP home network by the 3GPP accesses network, this process is carried out between the AS of user terminal and 3GPP home network equally, after authorizing successfully, AS distributes corresponding ownership PDG to user terminal, after setting up the tunnel between the PDG of user terminal by WAG in the 3GPP accesses network and distribution, user terminal gets final product the 3GPP PS territory business of access belonging network.

According to 3GPP agreement regulation, in the existing 3GPP-WLAN Internet, the authentication of WLAN user access network and licensing process may further comprise the steps as shown in Figure 3:

Step 301～302: current user terminal of WLAN and WLAN Access Network are set up wireless connections according to the flow process of 3GPP agreement regulation; Afterwards, initiate the access authentication procedure between current user terminal of WLAN and the 3GPP aaa server, this access authentication is undertaken by Extensible Authentication Protocol (EAP), carries out the mutual of EAP request and EAP response message between current user terminal of WLAN and 3GPP aaa server that is:.

After step 303～304:3GPP aaa server is received the access authentication request, judge the authentication information that self whether exists at current user terminal of WLAN, if there is no, then from HSS, obtain the authentication information of current user terminal of WLAN, such as: authentication five-tuple/tlv triple.And, if there is not the user signing contract information of current user terminal of WLAN in this 3GPPAAA server, such as: authorization message, user's temporary mark, will obtain from HSS equally.That is to say that the 3GPPAAA server self does not have user profile, just need from HSS, obtain.

Step 305:3GPPAAA server can send to strategy execution information the WAG in the visit public land mobile net network (VPLMN) that current user terminal of WLAN roams into, and this step is optional.

Step 306: if authentication and authorizing successfully, then the 3GPP aaa server sends to the WLAN Access Network and allows to insert message Access Accept, in this message, comprise EAP success message EAP Success, carry the connection authorization message in this success message, such as: insert filtering rule, tunnel attribute or the like.

After step 307:WLAN Access Network is received and allowed to insert message, send authentication success message EAP Success to current user terminal of WLAN.

Step 308: if current user terminal of WLAN does not have currently to provide access authentication 3GPP the register information of aaa server for it in HSS, then register in HSS for current user terminal of WLAN provides the 3GPPAAA server of authentication, the temporary mark according to the user in the registration message is determined the user.

In addition, according to the discussion of 3GPP agreement, among the 3GPP with WLAN on relevant network architecture and the flow process of short message service (SMS overWLAN), as shown in Figure 4.Fig. 4 is the short message supporting architecture that inserts based on IP, as can be seen from Figure 4, UE can be undertaken by the mobile switching centre (GMSC/SMS-IWMSC) of MSC or SGSN and gateway MSC/short message-IWF alternately, UE also can carry out alternately with GMSC/SMS-IWMSC by IP short message critical point (IP-SM-GW), wherein, IP-SM-GW is a newly-increased network entity in the existing mutual framework of 3GPP-WLAN, be used to provide the transmission of short message between IP client (Client) and the GSM/UMTS network, here, UE is exactly IP Client.That is to say that IP-SM-GW can use mobile application protocol (MAP, Mobile Application Protocol) and GMSC/SMS-IWMSC mutual, receives the short message that comes from GMSC/SMS-IWMSC, or sends SMS message to GMSC/SMS-IWMSC; Also can use the agreement and the IP Client that carry based on IP mutual, receive the short message that comes from IP Client, or send SMS message to IP Client.

Short message in the 3GPP standard is initiated (SM-MO, Short Message Mobile Origination) flow process, that is: IP Client may further comprise the steps to the transmission flow of Short Message Service Center (SM-SC, Short Message Service Centre) as shown in Figure 5:

Step 501:IP Client and PDG set up the tunnel, and here, IP Client is exactly WLAN UE.

Step 502: after the tunnel was set up, IP Client went up registration to IP-SM-GW.

Step 503:IP client uses based on the agreement of IP carrying and transmits short message to IP-SM-GW, and described agreement based on the IP carrying can be WAP, SMPP, MMPP, XML, SIP, SMTP.

Step 504:IP-SM-GW parses short message from IP message, the short message that adopts the MAP signaling be similar to the standard that MSC or SGSN use when SMS-IWMSC sends SMS message to parse to the SMS-IWMSC forwarding.Wherein, the MAP signaling of described standard defines in 3GPP TS23.040.

After step 505～506:SMS-IWMSC receives the short message that IP-SM-GW sends, transmit short message to SM-SC; After SM-SC received short message, sending SMS message to SMS-IWMSC sent report.Described repeating process, transmission reporting process all define in 3GPP TS23.040.

After step 507～508:SMS-IWMSC received report, sending SMS message to IP-SM-GW sent report; Send SMS message to IP Client by IP-SM-GW again and send report.Described SMS-IWMSC defines in 3GPP TS23.040 to the process that IP-SM-GW sends report.

Short message in 3GPP standard termination (SM-MT, Short Message M6bile Termination) flow process, that is: SM-SC may further comprise the steps to the transmission flow of IP Client as shown in Figure 6:

Step 601:SM-SC transmits short message to GMSC.

Step 602:GMSC sends sendRoutingInfoForShortMsg message to HLR/HSS, obtains the routing iinformation of UE, if IP Client registers in IP-SM-GW, then HLR/HSS returns the address information of IP-SM-GW.

Step 603:GMSC sends SMS message to IP-SM-GW, adopts to be similar to the MAP signaling of using to MSC or SGSN when SMS-IWMSC sends SMS message.

Step 604a: when the notice of short message is provided with when effective, IP-SM-GW sends SMS notification request message SMS notification request to IP Client, and notice IP Client has short message to be sent.

Step 604b: when the notice of short message is provided with effectively, when IP Client received SMS notificationrequest message, IP Client responded SMS notification request message, indicates whether to be ready to receive short message.

Step 605: when the notice of short message be provided with invalid, or IP-SM-GW has received after IP Client is ready to receive the indication of short message, IP-SM-GW transmits short message to IP Client, uses the agreement based on the IP carrying, as: WAP, SMPP, MMPP, XML, SIP, SMTP.

Step 606～607:IP-SM-GW sends SMS message to SMS-GMSC and sends report; After SMS-GMSC receives that short message sends report, to the HLR/HSS transmit status message that sends SMS message.This transmission report and transmit status process all define in 3GPP TS23.040.

Step 608:SMS-GMSC sends SMS message to SM-SC and sends report, and the process of this transmission report also defines in 3GPP TS23.040.

At present, only point out in the 3GPP standard that IP Client is before using short message service, need in IP-SM-GW, register, but do not define the idiographic flow of registration, the information notice HLR that does not also have definition how IPClient to be registered in IP-SM-GW, make GMSC or SMS-IWMSC when HLR/HSS gets the routing iinformation of IP Client, HLR/HSS can not return the address of IP-SM-GW, makes IP Client can't use the business in the 3GPP network.As seen, there is the imperfection part in flow process of the prior art, this problems affect the availability of flow process.

Embodiment

Core concept of the present invention is: a kind of service log-on flow process that inserts based on IP is provided, be applicable to that user terminal inserts the 3GPP network by IP and uses the situation of PS territory business, the present invention has provided the implementation procedure that user terminal is registered to IP-GW, and has provided the process of IP-GW with the log-on message notice HLR/HSS of user terminal.

Specific practice is: in the existing 3GPP-WLAN Internet, functional entity IP critical point (IP-GW) is set, is used to realize the service log-on of user terminal, and finish with HLR/HSS between relevant user terminal information mutual.When user terminal need insert the 3GPP network by IP network, user terminal sends the service log-on request to PDG earlier, after the PDG checking is passed through, send the service log-on request that carries user terminal identification information to IP-GW by PDG, this service log-on request is after the user information storage unit registration, and IP-GW returns the service log-on response via PDG to user terminal.Here, described user terminal is IP Client, just the WLAN user terminal; Described PDG is for supporting the PDG of institute's requested service; Described user information storage unit can be HLR or HSS.

Here, described IP-GW can be a logical functional entity of only supporting certain service log-on, such as: for only supporting the IP-SM-GW of short message service registration; It also can be the logical functional entity of supporting the multiple business registration simultaneously.Described IP-GW can be provided with one or more, and this IP-GW can independently be provided with, and also can be used as the logic function module and be arranged in the existing network equipment, such as: be arranged in the aaa server.

In above-mentioned processing procedure, that is mentioned specifically can have different implementations: IP-GW directly to register current service log-on request to user information storage unit in the user information storage unit registration service log-on request; Also can register current service log-on request to user information storage unit by aaa server.Wherein, described user information storage unit can be HLR or HSS.

In the above-mentioned processing procedure, carry out the IP-GW that mutual IP-GW can be certain appointment with PDG, such as: the IP-GW that IP Client carries when initiating the service log-on request; Also can be the IP-GW that contacts directly to be arranged with PDG, such as: user terminal accesses network of living in the associated IP-GW of this PDG; Can also be the IP-GW of IP Client ownership.

Below by two specific embodiments and accompanying drawing thereof, describe the specific implementation flow process of the inventive method in detail.

Embodiment one:

In the present embodiment, described user terminal is exactly IP Client, and IP-GW is for supporting the IP-SM-GW of short message service registration, and user information storage unit is HLR/HSS, and IP-SM-GW registers to the current business register requirement on the HLR/HSS by aaa server.The concrete processing procedure of present embodiment may further comprise the steps as shown in Figure 7:

Carry out alternately between step 701:IP Client and the relevant PDG, set up IP tunnel, this tunnel establishment procedure is the existing flow process of standard code, is not giving unnecessary details at this.This PDG is the PDG relevant with business.

Step 702:IP Client sends the service log-on request message via the tunnel with PDG foundation to PDG, carries the identification information of IP-SM-GW identification information and IP Client self in this request message.Wherein, described IP-SM-GW identification information can send with Domain Name Form registering sites, and PDG obtains the address information of IP-SM-GW by the domain name mapping mode; The identification information of described IP Client self can adopt network access Identifier (NAI).

Need to prove: also can not carry the IP-SM-GW identification information in the service log-on request that IP Client sends, PDG directly uses the IP-SM-GW that self gets in touch, and transmits the service log-on request to the IP-SM-GW that self gets in touch; Perhaps, PDG as NAI, parses the IP-SM-GW of IP Client ownership according to the IP Client identification information that carries in the service log-on request, transmits the service log-on request to the IP-SM-GW that parses.

After step 703～704:PDG receives the service log-on request, the corresponding relation of the Tunnel Identifier (Tunnel ID) of source IP address and distribution in the request that inspection IP Client sends, what guarantee IP Client use is that PDG initiates register requirement as source IP address to PDG for its IP address allocated when setting up the tunnel, after inspection is passed through, PDG is according to the IP-SM-GW address information that obtains, transmit the service log-on request to corresponding IP-SM-GW, carry IP Client identification information in the service log-on request of forwarding.

Here, it can be according to the information acquisition in the service log-on request that PDG obtains the IP-SM-GW address information, also can be the IP-SM-GW information acquisition of getting in touch according to self.

Step 705: the IP-SM-GW that receives the service log-on request, according to the IP Client identification information in the request, parse the address information of the aaa server that current IP Client is registered to, IP-SM-GW sends request user profile message according to the address information that obtains to aaa server then, portability IP Client identification information in this message, as NAI, and the SS7 address information of IP-SM-GW.

Here, before IP Client and PDG set up the tunnel, IP Client need be registered in the aaa server, and this process that is registered in the aaa server is the existing flow process of standard code, is not giving unnecessary details at this.

After step 706:AAA server is received request user profile message, according to the IPClient identification information that carries in the message, as NAI, obtain the related registration information of IP Client in aaa server, initiate registering flow path to HLR/HSS then, that is: send the registration request to HLR/HSS, carry the permanent identification of IP Client and the address information of IP-SM-GW in this request, the business information of this IP Client of notice HLR/HSS is registered in IP-SM-GW.

Here, the permanent identification of described IP Client can be MSISDN or IMSI; The address information of described IP-SM-GW sends with the SS7 coded system.

After step 707:HLR/HSS receives the registration request, the SS7 address information of storing IP-SM-GW, and know that IP Client can insert the PS territory of 3GPP by IP network, use the business in PS territory.At this moment, HLR/HSS can store corresponding sign, as storing IP-attached, shows that this IP Client can adopt IP to insert the business in PS territory.Afterwards, HLR/HSS returns register response to aaa server.

Here, optionally, HLR/HSS can be further with the register information of IP Client in HLR/HSS, is notified to application server (AS, Application Server) as the address information of IP-SM-GW.

After step 708:AAA server was received the register response of the success that HLR/HSS returns, aaa server returned to IP-SM-GW user profile message is provided, and can carry the permanent identification information of IP Client in this message, as MSISDN or IMSI;

Corresponding relation between the permanent identification of IP-SM-GW storing IP Client and the IP address of IP Client, further, this moment, IP-SM-GW can also be stored in the corresponding relation between the IP address of the PDG address known in the step 702 and IP Client.

Here, the corresponding relation between the IP address of the permanent identification of IP Client and IP Client can be stored in the independent database by IP-SM-GW or aaa server, and this database can be opened to other network entities and conduct interviews.

Step 709～710:IP-SM-GW returns the service log-on response message to PDG, after PDG receives, returns the service log-on response message to IP Client again.

Embodiment two:

In the present embodiment, described user terminal is exactly IP Client, and IP-GW is for supporting the IP-SM-GW of short message service registration, and user information storage unit is HLR/HSS, and IP-SM-GW directly registers to the current business register requirement on the HLR/HSS.The concrete processing procedure of present embodiment may further comprise the steps as shown in Figure 8:

Step 801～804: with whole processing of step 701～704 among the embodiment one with describe identical.

After step 805:IP-SM-GW receives the service log-on request, according to the IP Client identification information in the request, parse the permanent identification information of IP Client, as IMSI, and know the address information of the HLR/HSS of IP Client ownership according to IMSI, IP-SM-GW sends register request message to HLR/HSS then, portability IP Client identification information in this registration request, as resolving the IMSI that obtains, the SS7 address information of going back portability IP-SM-GW by NAI.

After step 806:HLR/HSS receives the registration request of IP-SM-GW,,, obtain the relevant information of this IP Client of self storage, as MSISDN, business information or the like as IMSI according to the identification information of IP Client; And, the SS7 address information of HLR/HSS storing IP-SM-GW.

HLR/HSS can know that IP Client can insert the PS territory of 3GPP by IP network by this registration request, uses the business in PS territory.At this moment, HLR/HSS can store corresponding sign, as storing IP-attached, shows that this IP Client can adopt IP to insert the business in PS territory.

Then, HLR/HSS returns register response to IP-SM-GW, carries the relevant information of IP Client in this response, as MSISDN, business information, aaa server address information or the like.

Here, optionally, HLR/HSS can be further with the register information of IP Client in HLR/HSS, is notified to application server as the address information of IP-SM-GW.

The IP Client relevant information that step 807:IP-SM-GW storage obtains from HLR/HSS, such as: the corresponding relation between the IP address of the permanent identification MSIDSN of storing IP Client and IP Client; Further, this moment, IP-SM-GW can also be stored in corresponding relation between the IP address of the PDG address known in the step 802 and IP Client.

Then, the aaa server address information that IP-SM-GW returns according to HLR/HSS sends the registration request to aaa server, carries IP Client identification information, IP-SM-GW address information.Wherein, IP Client identification information can be MSISDN, and the IP-SM-GW address information can be the address information of SS7 form.

After aaa server is received the registration request, the IP-SM-GW address information of storing this IP Client.

Step 808～809:IP-SM-GW returns the service log-on response message to PDG; PDG returns the service log-on response message to IP Client after receiving the service log-on response that IP-SM-GW sends.

For above-mentioned two embodiment, after IP Client finishes service log-on flow process in IP-SM-GW, follow-up MO flow process or the MT flow process that can carry out short message service.In the SM-MO flow process, IPClient sends SMS message to IP-SM-GW via PDG, IP-SM-GW receives after the short message of IP Client, can send authentication request to aaa server, the request aaa server carries out authentication to the professional ability that this IP Client sends SMS message, after the authentication success, IP-SM-GW is sent to SM-SC with short message via SMS-IWMSC/SMS-GMSC.

For embodiment two, because IP-SM-GW can obtain the business information of IP Client from HLR/HSS in step 806～807, therefore, in the SM-MO flow process, can carry out authentication to the professional ability that this IP Client sends SMS message by IP-SM-GW, not need to ask aaa server to carry out authentication.

In the SM-MT flow process, when GMSC/SMS-IWMSC when HLR/HSS gets the routing iinformation of IP Client, HLR/HSS can return the SS7 address of IP-SM-GW; GMSC/SMS-IWMSC could send SMS message to corresponding IP-SM-GW, carries the user ID that needs to receive short message in the message, as MSISDN; After IP-SM-GW receives short message, can send authentication request to aaa server earlier, the request aaa server carries out authentication to the professional ability of the receiving short-message of user of this MSISDN correspondence; After the success of aaa server authentication, IP-SM-GW matches the IP address of corresponding IP Client according to MSISDN, and according to the IP matching addresses of this IP Client to corresponding PDG address, send SMS message to corresponding PDG, PDG sends SMS message to IP Client by the tunnel with IP Client foundation.

For embodiment two, because IP-SM-GW can obtain the business information of IP Client from HLR/HSS in step 806～807, therefore, in the SM-MT flow process, can carry out authentication to the professional ability that this IP Client receives short message by IP-SM-GW, not need to ask aaa server to carry out authentication.

In the handling process of above-mentioned two embodiment, IP-SM-GW is used for the professional critical point that WLAN IP Client inserts 3GPP PS territory SMS business.In actual applications, because other business, register flow path as the register flow path of LCS business and above-mentioned short message is similar, therefore, IP-SM-GW can replace with the IP-GW that supports the different business registration, and above-mentioned register flow path also can be common to WLAN IP Client and insert all professional service log-on flow processs before in the 3GPP PS territory.

The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
