Embodiment 1

[0035] Embodiment 1 of the present invention provides a method for receiving interface connectivity information, such as image 3 shown, including:

[0036] Step 301, receiving a message sent by the base station through the X2 interface;

[0037] Step 302, acquiring interface connectivity information between the base station and neighboring base stations carried in the message.

[0038] The message is specifically a base station configuration update message.

[0039] Before step 302, it may also include:

[0040] Obtaining the serving cell information carried in the base station configuration update message, and judging according to the serving cell information that the base station configuration update message carries the configuration information of the base station's neighboring base stations or the configuration information of the base station; or

[0041] When the base station configuration update message carries a global base station identification information unit, d...

Embodiment 2

[0047] Embodiment 2 of the present invention provides a method for sending interface connectivity information. A base station sends a message through an X2 interface, and the message carries interface connectivity information between the base station and neighboring base stations.

[0048] Wherein, the message is specifically a base station configuration update message. The base station configuration update message carries the configuration information of the neighboring base stations of the base station or the configuration information of the base station according to the serving cell information carried; or the base station configuration update message carries the global base station identification information unit to distinguish whether to carry the The configuration information of the adjacent base stations of the base station, or the configuration information of the base station; or the configuration information of the adjacent base stations of the base station or the conf...

Embodiment 3

[0053] Embodiment 3 of the present invention provides a method for obtaining interface connectivity information. The DeNB sends the interface connectivity information between itself and neighboring base stations through the X2 interface. In the embodiment of the present invention, the device connected to the DeNB through the X2 interface takes RN as an example. introduction, such as Figure 4 As shown, the method includes the following steps:

[0054] In step 401, the DeNB sends an X2-AP message to the RN to initiate an X2 interface connectivity notification process, which is used for the DeNB to notify the RN of the X2 interface connectivity information of the DeNB.

[0055] Among them, the X2 interface connectivity information mainly includes: the identity of the adjacent base station with the X2 interface with the DeNB; the serving cell configuration information of the adjacent base station and the added, and / or modified, and / or deleted serving cell configuration informatio...

Abstract

The invention discloses a method, equipment and a system for transmitting and receiving interface connectivity information. A node B transmits a message which carries the interface connectivity information between the node B and a neighboring node B through an X2 interface, so that a relay node can acquire the interface connectivity information between the node B and the neighboring node B, and processes of switching, automatic neighbor relation, interference coordination, load balancing and the like can be accomplished.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for sending and receiving interface connectivity information. Background technique [0002] Since base stations usually have a relatively high cost, in the development of 3G (3rd-generation, third-generation mobile communication) technology, the construction of a large number of base stations will lead to relatively high network deployment costs. In order to reduce costs, relays are gradually introduced into cellular systems to increase the coverage of base station signals. Figure 1a The network architecture after introducing RN (Relay Node, relay node) for LTE-A (LTE-Advanced, evolved LTE) system, RN accesses the core network through the donor cell under the DeNB (donor base station), and the core network has no Direct wired interface, each RN can control one or more cells. Under this architecture, the interface between UE (User Equipment, user ter...
