Problems solved by technology

During the application process, if the network elements of the cellular network cannot know the status of the WLAN network where the user is located, for example, the quality of the WLAN link of the user is poor, or the user has left the original coverage of the WLAN while moving, this will lead to offloading and After the flow migration service is executed, the service flow is lost, the service is interrupted, and the user experience is reduced

Embodiment 1

[0075] Such as image 3 As shown, it is a schematic flow chart of the WLAN network actively reporting (via the AP / AC) the WLAN offloading information for offloading services of the WLAN network provided by the embodiment of the present invention. In this embodiment, the AC / AP performs the WLAN offloading information to the WMS. report. In the WLAN network architecture using thin AP+AC, the AC implements the reporting of relevant information. In the scenario where no AC is deployed, the fat AP can perform the reporting of relevant information. The specific steps are as follows:

[0076] Step 301: The AP / AC sends a WLAN offload information report message to the WMS. The message includes information such as link quality, location of the terminal, and network load of the AP / AC. The parameters contained in can be specifically selected as part or all of the above examples or extended for use. AP / AC can regularly report WLAN offload information to WMS or according to the policy, wh...

Embodiment 2

[0084] Figure 4 It is a schematic flowchart of the WLAN network actively reporting (through the terminal itself) the WLAN offloading information for offloading services of the WLAN network provided by the embodiment of the present invention. The difference between it and Embodiment 1 is that the WLAN offload information used for offloading services in the WLAN network is directly reported by the terminal, so that the WMS can obtain more accurate information related to the terminal. The specific steps are as follows:

[0085] Step 401: The terminal sends a WLAN offload information reporting message to the WMS. The message includes information such as link quality and the location of the terminal. In specific use, the parameters contained in the message can be selected according to specific circumstances. For some or all of the above examples or further extended use. The terminal can regularly report information to the WMS or according to the policy, when the reporting conditi...

Embodiment 3

[0093] Figure 5 It is a schematic flow diagram of the WLAN network passively reporting the WLAN offloading information used by the WLAN network for offloading services provided by the embodiment of the present invention, and the specific steps are as follows:

[0094] Step 501: The control network element of the cellular network or the fixed network offloading service sends a WLAN offloading information query request to the WMS. The message may include a request for various information parameters, or only include a request for a specific information parameter, such as only requesting the user terminal The signal strength of the WLAN network or the location, etc.;

[0095] Step 502: After receiving the WLAN offload information query request message, the WMS checks whether there is requested data in the local database that is still in the fresh cycle; if the data in the local database is still in the fresh cycle, then skip to step 507;

[0096] Step 503: The WMS sends a WLAN o...

Abstract

The invention discloses a method and a system for obtaining offload business information applied to a WLAN (wireless local access network). The method comprises steps that a mobile server is arranged in the WLAN; the mobile server acquires WLAN offload information of the WLAN, and transmits the information to offload business control network elements of a cellular network or a fixed network; and the offload business control network elements execute the offload business according to the WLAN offload information. According to the method and the system, a mobile server is newly added to a WLAN operation network to provide the fixed network or the cellular network with WLAN offload information such as link quality, position information and load condition of the WLAN where a user terminal is located, and therefore, the network is helped to perform precise determination and triggering on whether to perform offload or flow migration or not, correct execution of offload and flow migration are guaranteed, and user experience is ensured.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for obtaining distribution service information applied to a WLAN network when a cellular network, a wired fixed network and a WLAN network are merged and data services are distributed. Background technique [0002] At present, with the development of communication networks and the widespread use of multi-mode terminals, various data services are also developing rapidly, such as: web browsing, online games, media on demand, etc. Therefore, users have explosive data traffic. At the same time, the requirements for service experience are getting higher and higher, so that operators are facing more and more pressure on the network. For example, the problem of network congestion caused by multiple users using data services at the same time is becoming more and more serious. [0003] At present, the WLAN (Wireless Local Access Network, wireless local area networ...
