Abstract

Disclosed are a method and system for processing an online state of a user. In the method, an authentication, authorization and accounting (AAA) server receives a location update cancellation request message from a home location register (HLR); and after it is determined that a location update type in the location update cancellation request message is user location update, the AAA server keeps an online state of a user. According to the technical scheme provided in the present invention, a 3rd Generation Partnership Project (3GPP) user can be kept online simultaneously on a Wireless Fidelity (WiFi) network and a 3GPP network, thereby improving the engineering application value of a Wireless Fidelity Offload (WiFi Offload) scheme, and improving the user experience.

Description

User online status processing method and system

Technical field

The present invention relates to the field of communications, and in particular, to a method and system for processing a user's online state.

Background technique

Currently, the WiFi OffLoad (Cyber OffLoad) scheme in the related art refers to that a user in a 3rd Generation Partnership Project (3GPP) network roams or switches to a wireless local area network (WLAN) via a wireless local area network (WLAN). The access interface between the access network (abbreviated as WLAN AN) and the authentication and authorization (Acceptance, Accounting, AAA for short) server initiates an authentication and authorization request to the AAA server. The AAA interacts with the Home Location Register (HLR) through the D'/Gr' interface to authenticate the user. After the authentication is passed, the HLR will authorize the user subscription information to the AAA, which is authorized by the AAA to the user via the WLAN AN. At this point, the 3GPP user can directly access the Internet (Internet) through the WLANAN. Although the user is still a 3GPP user, it does not need to use 3GPP wireless and wired resources for data services, thereby effectively offloading the load of the 3GPP network. FIG. 1 is a schematic diagram of a WiFi OffLoad scheme according to the related art. The specific implementation process can be seen in Figure 1.

However, this WiFi OffLoad solution has the following drawbacks in actual deployment: 3GPP users roam or switch to WLAN, and start to access the Internet via WLAN AN. At this time, the user equipment (User Equipment, UE for short) receives the MMS or other data service notification sent from the 3GPP via the cellular radio link, and the UE will start the user registration process of the 3GPP network. After the UE registers successfully, the HLR sends a Cancel Location message to the 3GPP AAA server, thereby canceling the user's original location registration. The UE's link in the WLAN network will be disconnected, and the WLAN service can no longer be used directly through the WLAN AN. In this scenario, even if the UE switches back to the WLAN network from the 3GPP network, it still needs to re-authenticate and authorize to access the Internet via the WLAN AN.

It can be seen that the related technologies cannot ensure that the UE is online at the same time in the WLAN and the 3GPP network in the above scenario, and simultaneously uses two different network accesses.

detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

2 is a flow chart of a method of processing a user's online state in accordance with an embodiment of the present invention. As shown in FIG. 2, the method may include the following processing steps:

Step S202: The AAA server receives a cancel location update request message from the HLR.

Step S204: After determining that the location update type in the cancel location update request message is the user location update, the AAA server maintains the online state of the user.

In the related art, when a 3GPP user roams or switches to a WiFi network, if a data service message from the 3GPP cellular mobile communication link is received, the original WiFi link is disconnected. The method shown in FIG. 2 is used to modify the processing logic of the 3GPP AAA server after the Cancell Location is sent by the HLR, without disconnecting the original connection of the UE in the WiFi, thereby achieving the purpose of keeping the WiFi and the 3GPP network online at the same time. The invention solves the problem that when a 3GPP user roams or switches to a WiFi network in the related art, if a data service message from the 3GPP cellular mobile communication link is received, the original WiFi link is disconnected, thereby maintaining the 3GPP user in the WiFi and Simultaneous online on the 3GPP network, thereby improving the engineering application value of the WiFi Offload solution and improving the user experience.

Preferably, in step S204, after the AAA server determines that the location update type is the user location update, the online state may include the following operations:

Step S1: The AAA server extracts a location update type from the received cancellation location update request message;

Step S2: The AAA server determines whether the location update type is a user location update.

Step S3: If yes, the AAA server remains online.

In a preferred implementation process, the foregoing AAA server staying online may include the following process: the AAA server refuses to trigger the release of the user WiFi wireless side resource procedure according to the cancel location update request message.

As a preferred embodiment of the present invention, the AAA server receives the cancel location update request message from the HLR, and determines whether the location update type in the cancel location update request message is a user location update; if so, the AAA server keeps the user online The status is unchanged, that is, the process of releasing the user WiFi wireless side resource is not triggered according to the cancel location update message. Thus there is no 3GPP AAA server sending a Release User Radio Resource Request message to the GPRS Service Support Node (SGSN) or Gateway GPRS Support Node (GGSN) and the 3GPP AAA Server receiving the Release User Radio Resource Response message from the SGSN/GGSN.

Preferably, before the AAA server receives the cancel location update request message from the HLR, the AAA server may further include the following steps:

Step S4: The HLR determines whether the registration process of the 3GPP network triggered by the user after receiving the data service notification message via the 3GPP cellular radio link is successful;

Step S5: If yes, the HLR sends a Cancel Location Update Request message to the AAA server.

In a preferred embodiment, the UE interacts with the HLR via the WLAN AN and the 3GPP AAA server to successfully complete the EAP-SIM/EAP-AKA process, and after the authentication succeeds in obtaining the authorization information, the UE directly starts to use the data service through the AN. The UE receives the MMS or other data service notification sent from the 3GPP via the cellular radio link, initiates the user registration process of the 3GPP network, and completes the registration of the user. After the user successfully registers, the HLR sends a Cancel Location message to the 3GPP AAA server to cancel the location registration of the user in the 3GPP AAA server.

Preferably, after the AAA server remains online in step S204, the following operations may also be included:

Step S6: The AAA server returns a cancel location update response message to the HLR.

The above preferred implementation process will be further described below in conjunction with the preferred embodiment illustrated in FIG.

3 is a flow diagram of a method for a UE to keep WiFi and a 3GPP network online at the same time in accordance with a preferred embodiment of the present invention. As shown in FIG. 3, the preferred embodiment relates to a part involved in the interaction between the WLAN network and the 3GPP network after the user roams or switches to the WLAN network in the 3GPP network, that is, an interactive WLAN (Interworking WLAN, referred to as IWLAN), where The network elements may include, but are not limited to, AAA, HLR, WLAN AN, UE. The method can include the following processing steps:

Step S302: After the 3GPP user roams or switches to the WiFi network and establishes association with the WLAN AN, the UE sends an Extended Authentication Protocol (EAPoL)-Start message of the local area network to the WLAN AN to initiate an authentication request.

Step S304: The WLAN AN sends an Extended Authentication Protocol (EAP)-Request/Identity message to the WLAN UE.

Step S306: The WLAN UE replies with an EAP-Authentication/Identity (Response/Identity) message, and sends its user identity information to the network, where the identity information may be a pseudo-random NAI or a permanent NAI.

Step S308: The WLAN AN encapsulates the EAP packet by using a RADIUS Access Request (Access-Request) message, and encapsulates the Identity in the User-Name attribute of the RADIUS and sends the information to the 3GPP AAA server.

Step S310: The UE interacts with the HLR via the WLAN AN and the 3GPP AAA server to successfully complete the EAP-SIM/EAP-AKA process.

Step S312: After the authentication succeeds, the UE obtains the authorization information, and then directly uses the AN to start using the data service.

Step S314: The UE receives a multimedia message or other data service notification sent from the 3GPP via the cellular radio link, and the UE initiates a user registration process of the 3GPP network to complete the registration of the user.

Step S316: After the user successfully registers, the HLR sends a Cancel Location message to the 3GPP AAA server to cancel the location registration of the user in the 3GPP AAA server.

Step S318: The 3GPP AAA server keeps the online status of the user unchanged, and does not trigger the process of releasing the user WiFi wireless side resource according to the CancelLocation message, that is, the 3GPP AAA server does not send the release user radio resource request message to the SGSN/GGSN and the 3GPP AAA The server receives the release user radio resource response message from the SGSN/GGSN.

Step S320: The 3GPP AAA server responds to the HLR with a Cancel Location response message.

Step S322: The UE is out of the SGSN/GGSN and starts to use the data service in the 3GPP network.

Since the 3GPP AAA server does not trigger the release of the user WiFi radio side resource procedure in the WiFi network, the UE will keep the WiFi and the 3GPP network online at the same time. It can be seen that the technical solution provided by the embodiment of the present invention is simple and effective in actual use, and only needs to modify the processing logic of the 3GPP AAA server to meet the requirements of the entire WiFi OffLoad solution.
