Embodiment 1

[0074] see image 3 , is a schematic diagram of an application scenario of a method for simplifying WLAN authentication provided by an embodiment of the present invention, specifically including: several WLAN APs 31, multiple RAN management nodes 32, and several other RAN nodes 33, wherein several WLAN APs It is connected to a certain RAN management node on the RAN side of the wireless cellular network access network through a certain logical link, and the uplink and downlink data are managed by the RAN management node and distributed and aggregated through the management node. The RAN management node may also manage other RAN nodes.

[0075] The user supports the communication protocols of the wireless cellular network access network and the WLAN at the same time, and can maintain the communication connection on the side of the wireless cellular network access network when using the WLAN communication. The RAN management node connected by the user through the wireless cellul...

Embodiment 2

[0087] The second embodiment provided by the present invention is a special case of the first embodiment. This embodiment is applied to the situation when the wireless cellular network access network RAN ​​is Universal Mobile Telecommunications System-Terrestrial Radio Access Network (UTRAN, Universal Mobile Telecommunications System-Terrestrial Radio Access Network), specifically:

[0088] The RAN is UTRAN; the RAN management node is a radio network controller RNC in the UTRAN; other RAN nodes managed by the RAN management node are base stations NodeB.

[0089] The application scenario of the second embodiment is:

[0090] When the user enters the target RNC or target eNodeB (target RAN management node) from the source RNC (source RAN management node), according to the protocol, the source RNC will send a radio access network application part RANAP message of type "relocation request Relocation Required" to the core network. The "Source To Target Transparent Container" IE da...

Embodiment 3

[0101] The third embodiment is also another special case of the first embodiment. This embodiment is applied to the situation when the wireless cellular network adopts the LTE protocol, specifically:

[0102] The RAN is E-UTRAN; the RAN management node is an eNodeB; the eNodeB does not manage other RAN nodes;

[0103] When the user enters the target RNC or target eNodeB (target RAN management node) from the source eNodeB (source RAN management node), according to the protocol, the source eNodeB will send an interface application protocol S1AP message of the type "HandoverRequired" to the core network. The "Source To Target Transparent Container" IE data in this "Handover Required" type message will be directly transmitted to the target RNC or target eNodeB:

[0104] When the target management node is RNC, the "Source To Target Transparent Container" IE needs to include the "Source RNC To Target RNC Transparent Container" IE;

[0105] When the target management node is an eNo...

Abstract

Provided is a method for simplifying a wireless local area network authentication, a method, apparatus and system for storing a session key. The method for simplifying wireless local area network authentication comprises: a first access point, after successfully completing bidirectional authentication with a user, sending a session key of the user and the media access control (MAC) address of the user on a wireless local area network to a wireless radio access network (RAN) management node for storage; when the user switches from the first access point to a second access point, the second access point asks the RAN management node to which the second access point belongs about the session key of the user according to the MAC address of the user on the wireless local area network (101); and if the second access point finds the session key of the user, bidirectional authentication of the user will not be carried out and the session key will be used for encrypting the session content for protection (102). By means of the present invention, the number of times bidirectional authentication is performed is reduced, and both the delay in accessing access points on the wireless local area network and the load on authentication servers in the core network are reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for simplifying wireless local area network authentication. Background technique [0002] With the continuous increase of people's demand for wireless communication, the bandwidth of the existing wireless cellular network will be difficult to meet the future demand. Although the wireless cellular technology is constantly evolving, due to the constraints of the spectrum itself, the improvement of its throughput in the future will be relatively limited. In order to solve the bandwidth bottleneck of wireless communication, wireless cellular technology and WLAN technology are integrated. [0003] Currently, there are many solutions for the convergence of wireless cellular networks and WLANs. [0004] A kind of integrated technical solution is: the AP of WLAN is connected to a management node of the wireless cellular network access network (RAN) th...
