Embodiment 1

[0058] Method Embodiment 1: The source side judges the process of selecting a target network element to establish a direct interface.

[0059] This embodiment of the method describes the situation that in the address acquisition phase, after the target network element returns the address information, the source side decides to establish a direct interface to the target Femtocell or the Femtocell gateway. For the convenience of description, we use eNB1 to represent the source base station, and eNB2 to represent the target base station, where eNB1 can be a common macro base station or a home base station or a home base station gateway, and eNB2 accesses the MME through HeNB GW. The Cell2 belongs to the management of the eNB2. Such as image 3 As shown, the process of choosing to establish a direct interface in this method embodiment includes the following steps:

[0060] Step 101: eNB1 obtains the information of Cell2 according to the ANR.

[0061] Here, the information inclu...

Embodiment 2

[0073] Method Embodiment 2: The target side judges and selects a process for establishing a direct interface.

[0074] This method embodiment describes that the target side selects whether to establish a direct interface to the target Femtocell or Femtocell gateway and returns the corresponding selected address information, and the source side establishes the X2 direct interface according to the returned selected address information Case. For the convenience of description, we use eNB1 to represent the source base station, and eNB2 to represent the target base station, where eNB1 can be a common macro base station or a home base station and a home base station gateway, and eNB2 accesses the MME through the home base station gateway HeNB GW. Such as Figure 4 As shown, the process of establishing a direct interface in this method embodiment includes the following steps:

[0075] Steps 201 to 203 are the same as the descriptions of steps 101 to 103 in Method Embodiment 1, and ...

Abstract

The invention discloses a method for establishing direct interface selection. The method comprises the following step: when a target network element is accessed to a core network element through a target gateway, a source side or a target side selects to establish a direct interface with the target gateway and / or the target network element. The invention also discloses a system for establishing direct interface selection. The system comprises a selection establishing unit used for the source side or the target side to select to establish the direct interface with the target gateway and / or the target network element when the target network element is accessed to the core network element through the target gateway. By using the method and system provided by the invention, optional direct interfaces can be established so as to select various direct interface schemes.

Description

technical field [0001] The invention relates to a wireless cellular communication system, in particular to a method and system for selecting and establishing a direct interface. Background technique [0002] Home base stations are small, low-power base stations that are deployed in indoor places such as homes and offices. Insufficient coverage of cellular wireless communication systems. The advantages of femto base stations are affordable, convenient, low power output, plug and play, etc. [0003] Under the Long Term Evolution (LTE) system or Universal Mobile Telecommunications System (UMTS), Femtocell users connect to the core network through the Femtocell access network, such as figure 1 shown. The home base station access network is composed of the home base station and the home base station gateway. The main functions performed by the femtocell gateway are: verifying the security of the femtocell, processing the registration and access control of the femtocell, and b...
