Embodiment 1

[0123] Figure 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 Figure 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...

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 invention provides a processing method and a processing device for a secondary evolved Node B (SeNB). The processing method comprises the steps that: a mobility management entity (MME) receives a first request message from a master evolved Node B (MeNB), wherein the first request message is used for requesting to conduct dual connection processing on the SeNB; and the MME sends a second request message to the SeNB according to the first request message, wherein the second request message is used for requesting the SeNB to conduct dual connection processing. By means of the processing method and the processing device, the problem existing in the related art that a dual connection of an evolved Node B cannot be realized when an X2 interface does not exist is solved, thus the effect that the dual connection of the evolved Node B can be realized in the case where no X2 interface exists is achieved.

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), and a user equipment or terminal (User Equipment , referred to as UE) and base station (eNodeB, referred to as eNB) is a UU interface, between eNB and MME is S1-MME (S1 for the control plane) interface, between eNB and SGW is S1-U interface, eNB Between them are X2-U (X2-User plane) 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: L1 protocol, L2 protocol, Internet Protocol (Internet Protocol, re...
