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 ProxyFe-GW is separated from the ServingFe-GW, when information interaction is required between the two types of functions, the signaling interaction must be performed through the interface between the two Fe-GWs, which affects efficiency and wastes resources.

Embodiment 1

[0120] Image 6 It is a flow chart of Embodiment 1 of the method for accessing the Femtocell to the access gateway of the present invention. In this embodiment, when the Fe-GW (ServingFe-GW) registered by the Femtocell and the ProxyFe-GW used by the Se-GW are not the same When there is one Fe-GW, initiate the redirection process of ProxyFe-GW, and migrate ProxyFe-GW to ServingFe-GW, so as to achieve the purpose of integrating the two Fe-GWs. The specific implementation steps are as follows:

[0121] Step 601: see image 3 In step 310 shown, the SONServer 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 identifier (Fe-GWID) 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.

[0123] Step 602: the Fe-GW sends a Fe-GW regist...

Embodiment 2

[0154] Figure 8 It is a flow chart of Embodiment 2 of the method for accessing a Femtocell to an access gateway in the present invention. Similar to Embodiment 1, the ProxyFe-GW is migrated to the ServingFe-GW through the Proxy redirection process, so that the two Fe- The purpose of 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 ServingFe-GW (via a registration request message); forwarded, the Serving Fe-GW can find the Se-GW through routing information. At this time, the ServingFe-GW sends a message to the Se-GW (the authenticator therein, that is, the AAA client) to trigger it to execute Proxy redirection.

[0158] Step 804: The Se-GW returns a redirect response message to the ServingFe-GW. Afterwards,...

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 AAAProxy redirection execution 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 above (and its modified embodiments), Se-GW can receive messages from ServingFe-GW or ProxyFe-GW or Femto-AAA to change Proxy, and these messages all carry ServingFe-GW logo. 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 Se-GW receives the message of changing the Proxy, Se-GW (the AAA client in it) sends an access request message to ServingFe-GW; ServingFe-GW now acts as the AAA- Proxy, which sends the access request to Femto-AAA.

Abstract

The invention discloses a method for a home base station to access an access gateway, comprising: after receiving a registration request of the home base station, serving the home base station access gateway Serving? The Fe-GW determines whether it is the proxy Femto access gateway Proxy of the security gateway Se-GW? Fe-GW, when to send change Proxy to Se-GW? Fe-GW message, or through the proxy? The Fe-GW forwards the message of changing the Proxy Fe-GW to the Se-GW; the Se-GW sends the Serving? Fe-GW as a proxy? Fe-GW. The invention also discloses a system for connecting a home base station to an access gateway. The present invention avoids the situation that two Fe-GWs serve the home base station after the home base station is connected to the network by modifying the existing home base station network access flow, and simplifies the subsequent communication processing flow.

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, FemtoGateway) through the security gateway (Se-GW, SecurityGatew...
