Embodiment 1

[0036] Such as Figure 5 As shown, when the source eNB is a macro eNB and the target eNB is a HeNB, it is a schematic flow diagram of inbound handover from the macro eNB to the HeNB, which specifically includes the following steps:

[0037] Step S501, when the target HeNB is in the closed mode, the macro eNB requests the MME to determine whether the UE is allowed to access; or, when the target HeNB is in the mixed mode, the macro eNB requests the MME to determine the membership of the UE in the target HeNB.

[0038]In step S502, if the UE is allowed to access, the macro NB sends an X2 AP handover request message to the HeNB GW. For a mixed-mode CSG cell, the handover request message should carry the access mode of the UE in the target HeNB.

[0039] In step S503, the HeNB GW constructs an S1 AP handover request message according to the X2 AP handover request message. and send the message to the target HeNB.

[0040] In step S504, the target HeNB judges whether the UE can ac...

Embodiment 2

[0045] Such as Image 6 As shown, when the source eNB is a HeNB and the target eNB is a macro eNB, it is a schematic flow diagram of the outbound handover from the HeNB to the macro eNB, which specifically includes the following steps:

[0046] Step S601, the source HeNB initiates an S1 handover, and sends an S1 AP handoverrequired message to the HeNB GW.

[0047] Step S602, after receiving the S1 AP handover required message, the HeNB GW constructs an X2 AP handover request message according to the message and the saved UE context message of the HeNB, and sends the X2AP handover request message to the target macro eNB.

[0048] It is worth noting that if there is no HeNB UE context message in the HeNB GW, the new S1 AP procedure needs to be used to request the HeNB context from the MME. This new S1 AP process should be a class 1 process, which is a related command of the UE. Such as Figure 7 As shown in , it is a schematic diagram of the process of the HeNBGW requesting t...

Abstract

The invention provides a switching method and a system, wherein the method comprises the steps of: using an HeNB GW to receive a switching request sent by a source eNB, and convert the switching request into a switching request in accordance with an interface form between the HeNB GW and an object eNB, and then send the switching request to the object eNB; enabling the object eNB to send a confirmation message of the switching request to the HeNB GW if the object eNB allows the switching request of the source eNB; using the HeNB GW to receive the confirmation message of the switching request sent by the object eNB, convert the confirmation message of the switching request into the confirmation message of the switching request in accordance with the interface form between the source eNB and the HeNB GW, and then send the confirmation message of the switching request to the source eNB. According to the invention, the switching between a macro eNB and a home evolved nodeB is realized through an interface S1 between the HeNB and the HeNB GW and an interface X2 between the HeNB GW and the macro eNB, and the core network pressure is reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a switching method, system and device. Background technique [0002] Such as figure 1 As shown, the E-UTRAN in R9 includes a network architecture of a HeNB (Home Evolved NodeB, home evolved base station). Among them, the X2 interface is used between eNBs (also referred to as macro eNBs below), and the S1 interface is used between eNBs and MME (Mobility Management Entity, mobile management entity). Node) is connected to the MME, but there is no interface between HeNBs, and the HeNB can only be connected to one HeNB GW at the same time. [0003] in such as figure 1 In the network architecture shown, currently there is no X2 interface between the HeNB and the macro eNB. Therefore, the handover between the macro eNB and the HeNB is realized through the S1 interface. The specific implementation process is as follows: figure 2 shown, including the following st...
