Embodiment 1

[0123] Image 6 It is a flowchart of a method for realizing dual connectivity of a base station according to Embodiment 1 of the present invention, as shown in Image 6 As shown, the method includes the following steps:

[0124] Step S602, the MeNB sends the message (corresponding to the above-mentioned first request message) encapsulated with the X2 AP to the MME;

[0125] Step S604, the MME sends the encapsulated X2 AP message (corresponding to the above second request message) to the SeNB;

[0126] Step S606, the SeNB sends the message encapsulated with the X2 AP (the message may be a processing request message, or a processing message processed by the SeNB) to the MME;

[0127] In step S608, the MME sends the message encapsulated by the X2 AP (the message may be a processing request message, or a processing message processed by the SeNB) to the MeNB.

[0128] Among them, there is no X2 interface between MeNB and SeNB, and messages between base stations can be sent and r...

Embodiment 2

[0133] Figure 7 It is a flowchart of a method for implementing dual connectivity of a base station according to Embodiment 2 of the present invention. This embodiment is described by taking the processing flow of adding SeNB as an example, as shown in Figure 7 As shown, the method includes the following steps:

[0134] Step S702: the MeNB sends an addition requirement message (corresponding to the above-mentioned first request message) to the MME. It includes at least the S1 APID information assigned to the UE by the MeNB and the MME, and the routing information of the target SeNB, such as SeNB ID and TAI. And some content included in the SeNB addition request message on other existing X2 AP interfaces (corresponding to the above processing information).

[0135] Step S704: The MME sends an addition request message (corresponding to the above-mentioned second request message) to the target SeNB. This message is sent from the MME to the target SeNB, at least including the ...

Embodiment 3

[0141] Figure 8 It is a flowchart of a method for realizing dual connectivity of a base station according to Embodiment 3 of the present invention. This embodiment is described by taking the processing flow of modifying SeNB as an example, as shown in Figure 8 As shown, the method includes the following steps:

[0142] Step S802: the MeNB sends a modification request message (corresponding to the above-mentioned first request message) to the MME. It includes at least the S1 APID information assigned to the UE by the MeNB and the MME, and the routing information of the target SeNB, such as SeNB ID and TAI. And some content included in the SeNB modification request message on other existing X2 AP interfaces (corresponding to the above-mentioned processing information).

[0143] Step S804: the MME sends a modification request message to the SeNB. The message at least contains the S1 APID information allocated to the UE by the SeNB and the MME, and part of the content contain...

Abstract

The present invention provides a processing method and device for a secondary base station SeNB, wherein the method includes: a mobility management entity MME receives a first request message from a primary base station MeNB, wherein the first request message is used to request the SeNB to perform Dual connectivity processing: the MME sends a second request message to the SeNB according to the first request message, where the second request message is used to request the SeNB to perform dual connectivity processing on the SeNB. The invention solves the problem in the related art that the dual connectivity of the base station cannot be realized when there is no X2 interface, and further achieves the effect that the dual connectivity of the base station can be realized even when there is no X2 interface.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a processing method and device for a SeNB. Background technique [0002] figure 1 It is a schematic diagram of the overall architecture of the medium and long-term evolution system of related technologies, such as figure 1 As shown, the Long Term Evolution (LTE for short) architecture includes: a Mobility Management Entity (MME for short), a Serving GetWay (SGW for short), a user equipment or a terminal (UserEquipment, The UU interface is between the UE for short) and the base station (eNodeB, eNB for short), the S1-MME (S1 for the control plane) interface between the eNB and MME, the S1-U interface between the eNB and SGW, and the S1-U interface between the eNB and the MME. Between them are the X2-U (X2-Userplane) and X2-C (X2-Control plane) interfaces. In LTE, the protocol stack of the S1-MME interface is divided into the following protocol layers from bottom to top: L...
