Problems solved by technology

[0010] 4) For UE bearers established or transferred to CSG small cells, the core network does not know that they occupy CSG resources, and the core network cannot support CSG-based charging
[0011] 5) When an inter-MeNB handover occurs, the source eNB does not know that the SeNB cell under the target MeNB is a CSG cell, and will trigger X2 handover. When the target MeNB receives the handover request, it can establish the UE on the CSG small cell, but there is currently no signaling Notify the core network to authenticate the UE according to the UE's CSG subscription information

Embodiment 1

[0111] The schematic diagram of Embodiment 1 of the method for supporting bearer establishment in the present invention is as follows Figure 4 shown. This embodiment is applicable to the scenario where the SeNB has a direct interface with the MeNB, and the MeNB establishes the bearer to the SeNB cell supporting CSG when the bearer is established during the UE attach or location update process, where SeNB1 and SeNB2 are two SeNBs under the MeNB. Figure 4 The shown method includes the following steps:

[0112] Step 401: The MeNB obtains the CSG ID and / or cell access mode supported by the SeNB cell through OAM, or during the establishment of the interface between the MeNB and the SeNB, or during the eNB configuration update process. During UE attach or location update process, MeNB can report the CSG identity supported by the SeNB cell covered by MeNB to MME in two ways, which are step 403 and step 406 respectively.

[0113] Step 402: UE initiates an attach request or a locat...

Embodiment 2

[0140] The schematic diagram of Embodiment 2 of the method for supporting bearer establishment in the present invention is as follows Figure 5 shown. This embodiment is applicable to the scenario where the SeNB has a direct interface with the MeNB, and when the UE switches to the MeNB through S1 handover, the MeNB establishes a bearer to the SeNB cell supporting CSG. Figure 5 The shown method includes the following steps:

[0141] Step 501: The MeNB obtains the CSG identity and / or cell access mode supported by the SeNB cell through OAM, or during the establishment of the interface between the MeNB and the SeNB, or during the eNB configuration update process. During the S1 handover process, the CSG identity supported by the SeNB cell covered by the MeNB can be reported to the MME in two ways, which are step 502 and step 505 respectively.

[0142] Step 502: During the establishment of the X2 interface between the source eNB and the target MeNB or during the eNB configuration...

Embodiment 3

[0156] The schematic diagram of Embodiment 3 of the method for supporting bearer establishment in the present invention is as follows Figure 6 shown. This embodiment is applicable to a scenario where the SeNB has a direct interface with the MeNB, and when the UE switches to the MeNB through X2 handover, the MeNB establishes a bearer to the SeNB cell supporting CSG. Figure 6 The shown method includes the following steps:

[0157] Step 601: The MeNB obtains the CSG identity and / or cell access mode supported by the SeNB cell through OAM, or during the establishment of the interface between the MeNB and the SeNB, or during the eNB configuration update process.

[0158] Step 602: the source eNB sends a handover request to the target MeNB.

[0159] Step 603: The target MeNB establishes the UE bearer under the MeNB cell, and sends a handover request confirmation to the source eNB.

[0160] Step 604: The source eNB sends RRC reconfiguration to the UE.

[0161] Step 605: The targ...

Abstract

The invention discloses a method for supporting bearer establishment. The method comprises the steps that a MeNB sends CSG identifiers supported by cells under all auxiliary base stations SeNB and under the coverage of the MeNB to an MME or a CSG identifier of a cell where UE is placed under the SeNB to the MME; the MeNB receives an admittance authentication result of the UE in the cell corresponding to the CSG identifier from the MME, and a UE bearer is established in a cell corresponding to immigration or emigration according to the admittance authentication result and / or the CSG member status of the UE in a mixed cell. The invention further discloses the method for supporting bearer establishment, a base station and the MME. According to the technical scheme, the UE bearer can be correctly established or transferred to the appropriate cell.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method for supporting bearer establishment, a base station and a mobility management entity. Background technique [0002] Modern mobile communication tends to provide users with high-speed multimedia services, such as figure 1 Shown is the system architecture diagram of System Architecture Evolution (SAE). in: [0003] User Equipment (UE) 101 is a terminal device for receiving data. Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 102 is a radio access network including macro base stations (eNodeBs / NodeBs) that provide UEs with an interface to access the radio network. Mobility Management Entity (MME) 103 is responsible for managing UE's mobility context, session context and security information. Serving Gateway (SGW) 104 mainly provides user plane functions, and MME 103 and SGW 104 may be in the same physical entity. The packet da...
