Problems solved by technology

[0004] In the process of implementing the present invention, the inventor found the following problems in the prior art: the relay node may configure the wrong home base station, and the home base station cannot judge whether the UE or the relay node is requesting to connect, so that the home base station may be wrongly configured. The relay node is configured as a UE, and the relay node exchanges information with other adjacent relay nodes or adjacent base stations of the home base station, resulting in a long delay

Embodiment 1

[0075] Embodiment one

[0076] In the embodiment of the present invention, information bits can be added or defined in the message of the synchronization channel (SCH, Synchronization Channel) / broadcast channel (BCH, Broadcast Channel) of the base station and / or relay node, or can be included in the information block of the system message Add or define information bits in (SIB1, System Information Block), the information bits are used to indicate the node type, as shown in Table 1, the base station can use the node type information of the node to indicate that it is a base station, an already running relay node The node type information may also be used to indicate that it is a relay node, or indicate whether to support relay node access.

[0077] After adding this information bit, the relay node that needs to access the network can request the common base station to establish a connection with the home base station, or request the relay node to establish a wireless X2 interfa...

Embodiment 2

[0083] see figure 2 , is a specific flowchart of a method for establishing a connection between a relay node and a network node provided in Embodiment 2 of the present invention. In this embodiment, the relay node takes a newly powered-on relay node as an example, but does not Limited to this, the relay node can initiate a connection establishment request with the home base station to the selected base station according to the obtained node type of the adjacent network node, and the specific process includes:

[0084] Step 201: Obtain the node type (such as eNB type) of the adjacent network node;

[0085] For example, the relay node 2 acquires the node type of the adjacent network node, and selects a home base station (such as the base station in the figure) to be connected according to the node type of the adjacent network node; wherein, the acquisition method may be By receiving the node type of the adjacent network node sent by the adjacent network node through the system...

Embodiment 3

[0092] refer to image 3 , is a signaling flowchart of a method for establishing a connection between a relay node and a network node provided in Embodiment 3 of the present invention. In this embodiment, if the relay node (for example, relay node 2 in the figure) cannot know the adjacent If the node type of the node does not receive the broadcast information containing the node type sent by the adjacent node, it can directly initiate a request to the base station to establish a connection with the home base station. The specific process includes:

[0093] Step 301: When a relay node (such as relay node 2) randomly selects a home base station (such as the eNB in ​​the figure) to be connected according to the network node to be selected, its own needs and network status;

[0094] Step 302: the relay node 2 sends a connection establishment request to the home base station to be connected, and the connection establishment request includes its own node type, where the node type is...

Abstract

The invention discloses a connection establishment method and a connection establishment device for a relay node and a network node. The method comprises the following steps of: sending connection establishment request information which comprises a node type and / or a connection type of the connection establishment request information to a selected network node to be connected; and receiving connection establishment response information sent by the network node to be connected. By adopting the technical scheme, the relay node can automatically establish a connection with a home base station (HBTS), establish a wireless X2 interface, and directly interact information with other network nodes, so that the time delay of the information interaction is reduced; and the network is capable of self-configuration and self-optimization, so that the performance of the network is improved.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and device for establishing a connection between a relay node and a network node. Background technique [0002] In order to solve the coverage problem of the base station, it is usually necessary to use a relay node (RN, Relay Node) to enhance the wireless communication signal between the base station (eNB) and the mobile station (MS, Mobile Station). The relay node communicates with the base station through a wireless link. A base station serving a relay node is called a home base station. One or more relay nodes can be deployed under a base station. Information exchanged between the relay node and other network nodes needs to be forwarded through its home base station (Donor-eNB). [0003] In the existing technology, the operator determines the home base station for the deployed relay node, so that the relay node can successfully connect to its home base station, a...
