Problems solved by technology

Therefore, the subsequent ServingFe-GW cannot correctly process the above-mentioned data and signaling, for example, cannot identify the sending end of the data and signaling (that is, the home base station), etc.
[0031] In addition, when the Proxy Fe-GW is separated from the Serving Fe-GW, when information exchange is required between the two types of functions, signaling must be exchanged through the interface between the two Fe-GWs, which affects efficiency and wastes resources

Embodiment 1

[0120] Figure 6 It is a flow chart of Embodiment 1 of the method for accessing a Femtocell to an access gateway according to the present invention. In this embodiment, when the Fe-GW (Serving Fe-GW) registered by the Femtocell and the ProxyFe-GW used by the Se-GW are not When the same Fe-GW is used, the Proxy Fe-GW redirection process is initiated, and the Proxy Fe-GW is migrated to the Serving Fe-GW to achieve the purpose of combining the two Fe-GWs. The specific implementation steps are as follows:

[0121] Step 601: see image 3 In Step 310 shown, the SON Server allocates an Fe-GW to the Femtocell according to conditions such as the load of the Fe-GW, and at the same time sends the Fe-GW ID (Fe-GW ID) to the Femtocell.

[0122] The above identifier may be the IP address of the Fe-GW, the identifier assigned by the IEEE of the Fe-GW, domain name information, or other identifiers that can help the Fe-GW to be found by the Fe-GW.

Embodiment 2

[0154] Figure 8 It is the flow chart of the second embodiment of the method for accessing the home base station to the access gateway of the present invention. Similar to the first embodiment, the Proxy Fe-GW is migrated to the Serving Fe-GW through the Proxy redirection process, so that the two The purpose of Fe-GW integration, the specific implementation steps are as follows:

[0155] Step 801 to step 802: same as step 601 to step 602.

[0156] Step 803: Serving Fe-GW sends a change proxy request to Se-GW.

[0157] Since the Femtocell knows the identity of the Se-GW, the Femtocell can provide the identity of the Se-GW to the Serving Fe-GW (via a registration request message); or, because the Femtocell sends a registration request to the Serving Fe-GW through the Se -GW forwarded, then the Serving Fe-GW can find the Se-GW through routing information. At this point, the Serving Fe-GW sends a message to the Se-GW (the authenticator therein, that is, the AAA client) to trigg...

Embodiment 3

[0166] Figure 9 It is a flow chart of the third embodiment of the method for accessing the home base station to the access gateway of the present invention. This embodiment describes an example of the execution of AAA Proxy redirection of the Se-GW, and the specific steps are as follows:

[0167] Step 901: Proxy change trigger.

[0168] As described in the first and second embodiments (and its modified embodiments), the Se-GW can receive messages from the Serving Fe-GW or Proxy Fe-GW or Femto-AAA to change the Proxy, and these messages all carry the Serving Identification of Fe-GW. The Se-GW can also self-trigger to change the Proxy, and it can self-detect that the Serving Fe-GW and the Proxy Fe-GW are not the same Fe-GW.

[0169] Step 902 to Step 903: After the Se-GW receives the message of changing the Proxy, the Se-GW (the AAA client in it) sends an access request message to the Serving Fe-GW; AAA-Proxy, which sends the access request to Femto-AAA.

[0170] Step 904 to...

Abstract

The invention discloses a method for accessing a femto to an access gataway. The method comprises the following steps: after receiving the register request of a femto, determining whether a serving Fe-GW is a proxy Fe-GW of a Se-GW or not by the serving Fe-GW; and if not, sending a message of changing the Proxy Fe-GW to the Se-GW, or forwarding a message of changing the Proxy Fe-GW to the Se-GW through the Proxy Fe-GW, wherein the Se-GW uses the Serving Fe-GW as the Proxy Fe-GW. The invention also discloses a system for accessing the femto to the access gataway. According to the invention, the situation that two Fe-GWs serve the femto after the femto accesses a network is avoided through modifying the traditional femto network access procedure, and the subsequent communication processing procedures are simplified.

Description

technical field [0001] The present invention relates to home base station access technology, in particular to a method and system for home base station access to access gateway. Background technique [0002] In order to provide mobile users with higher service rates and lower service costs, and at the same time, in order to make up for the lack of coverage of existing distributed cellular wireless communication systems, Femtocells are usually set up in places such as homes and office areas. The femtocell is a small, low-power base station, which has the advantages of practicality, convenience, and low power output. [0003] figure 1 is a schematic diagram of a communication network model including a home base station (also known as a home base station), such as figure 1 As shown, in the home base station access service network, the home base station is connected to the home base station access gateway (Fe-GW, Femto Gateway) through the security gateway (Se-GW, SecurityGate...
