Problems solved by technology

When ProxyFe-GW and ServingFe-GW are not the same Fe-GW, Figure 5 The flow shown does not execute correctly
On the one hand, the de-network process does not involve the ServingFe-GW, which will cause the information stored in the ServingFe-GW to not be updated or deleted, resulting in its resources not being released; on the other hand, because the Fe-GW that accepts Femto-AAA It is a ProxyFe-GW, but the Fe-GW is not the Fe-GW registered by the Femtocell (that is, it is not the ServingFe-GW of the Femtocell), so sending a logout request to the Femtocell cannot achieve the purpose of triggering the Femtocell to withdraw from the network
[0027] 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

[0079] Figure 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, the BootstrapServer provides the Fe-GW for the Femtocell to be connected to, and the Se-GW selects the final required Fe-GW for the Femtocell. The connected Fe-GW specifically includes the following steps:

[0080] Step 601: The femtocell uses a preset certificate to establish a secure connection with the BootstrapServer. The secure connection can be established based on the Secure Sockets Layer (SSL, SecureSocketsLayer) protocol.

[0081] Step 602: the HNB requests the BootstrapServer to obtain configuration parameters, and the HNB may send its location information to the BootstrapServer.

[0082] Step 603: The BootstrapServer allocates the Se-GW and the Fe-GW to which the HNB needs to be connected to for the HNB.

[0083] The BootstrapServer may allocate the Se-GW to the Femtocell according to the location inform...

Embodiment 2

[0107] Figure 7 It is a flow chart of the second embodiment of the method for accessing the home base station to the access gateway of the present invention. In this embodiment, the Se-GW selects an Fe-GW for the home base station to connect to, which specifically includes the following steps:

[0108] Step 701 to step 702: same as step 605 to step 606.

[0109] Step 703: the HNB sends an identity authentication request message to the Se-GW, so as to realize mutual authentication between the HNB and the Se-GW.

[0110] Step 704: Se-GW selects an Fe-GW for the HNB.

[0111] As described in Embodiment 1, the Se-GW and the Fe-GW belong to the same domain, that is, both belong to the home base station access service network, and the Se-GW can know information such as the current load and location of the Fe-GW to which it is connected. Yes, the Se-GW can query these messages through the management plane. The Se-GW may select a Fe-GW with the smallest load among these Fe-GWs, or...

Embodiment 3

[0121] Figure 8 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. In this embodiment, the Se-GW tries the Fe-GWs it can connect to one by one, and the Fe-GW determines the status information according to its own load and so on. Deciding whether to allow Femtocell access, specifically includes the following steps:

[0122] Step 801 to step 803: same as step 701 to step 703.

[0123] Step 804: The Se-GW tries the Fe-GWs it can connect to one by one, and sends an access request to the Fe-GW.

[0124] Step 805: Assume that Se-GW first sends an access request to Fe-GW1. After receiving the access request, the Fe-GW judges its current load situation, and judges whether providing services for a new Femtocell will cause adverse consequences such as load overload or exceeding the load threshold. It is assumed here that Fe-GW1 judgments will cause adverse consequences.

[0125] Step 806: Fe-G...

Abstract

The present invention discloses a method for a home Node B (HNB) accessing an access gateway. The method includes that: when the HNB accesses a network, a bootstrap server selects a security gateway Se-GW and a HNB gateway Fe-GW for the HNB, wherein the Fe-GW is connected to the Se-GW; the selected Fe-GW information is sent to the HNB. At the same time, the present invention discloses a system for the HNB accessing the access gateway. With modifying the existing procedure that the HNB accesses network, the present invention avoids the case that there are two Fe-GWs for severing the HNB after the HNB accesses the network, thus simplifying the procedure of the subsequent communication.

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...
