Embodiment 1

[0089] Such as figure 2 As shown, it is a flowchart of the access method provided by Embodiment 1 of the present invention, including the following steps:

[0090] S201: The first node sends an access request message to at least one selected second node, for requesting the second node to serve as a donor (Donor) node of the first node and provide a backhaul service for the first node.

[0091] S202: The second node judges whether it can serve as the Donor node of the first node based on the received access request message, and sends an access response message to the first node based on the judgment result.

[0092] S203: The first node determines, according to the received access response message of the second node, a node that can serve as a Donor node of the first node among the at least one second node.

[0093] In S201, the first node may select a second node occupying a frequency point supported by itself to send an access request message, in which the second node is re...

Embodiment 2

[0157] Such as image 3 As shown, it is a flow chart of the access method provided by Embodiment 2 of the present invention, Figure 4 It is a scenario of the application of this embodiment, and it is a schematic diagram of backhaul link access for small stations in a distributed network; Figure 4 Among them, A and B are small stations with wired backhaul links, which are connected to the core network through optical fibers. C~F are self-deployment or plug-and-play small stations. You can choose macro base stations or A, B acts as the donor node.

[0158] This embodiment two comprises the following steps:

[0159] S301: The first node (such as AP0) performs neighbor cell measurement after starting up.

[0160]Specifically, the frequency points supported by APO include 2.0GHz and 3.4GHz-3.6GHz. An evolved base station (evolved Node B, eNB) adjacent to APO works at 2.0 GHz, and an AP adjacent to APO works at 3.5 GHz. AP0 performs neighbor cell measurement to obtain RSRP me...

Embodiment 3

[0176] Such as Figure 6 As shown, it is a flow chart of the access method provided by Embodiment 3 of the present invention, including:

[0177] S601: The first node sends an access request message to at least one selected second node, for requesting the second node to serve as a Donor node of the first node and provide backhaul service for the first node;

[0178] S602: The first node determines a node among the at least one second node that can serve as a Donor node of the first node according to the received access response message of the second node.

[0179] Optionally, in S601, the first node selects the at least one second node according to the following steps:

[0180] Perform neighbor cell measurement; select the at least one second node according to the neighbor cell measurement result.

[0181] Alternatively, the at least one second node is selected according to the following steps:

[0182] receiving backhaul information sent by at least one neighboring cell no...

Abstract

The invention relates to the field of communication technology, and particularly to an access method and an access device. The access method and the access device are used for settling a problem of incapability of satisfying an access requirement which is flexibly configured in a UDN in a manner of pre-configuring a donor node for a low-power small-coverage access node and configuring the donor node through OAM. The access method provided by the embodiment of the invention comprises the steps of transmitting access request information by a first node to at least one selected second node for requesting the second node as the donor node of the first node to provide a backhaul service for the first node; and determining a fact that at least one second node can be used as the node of the donor node of the first node by the first node according to the received access response information of the second node. According to the access method and the access device, the donor node which provides the backhaul service can be flexibly and conveniently selected for a plug-and-play access point, and configuration of a donor cell list for the access point through OAM is not required, thereby saving configuration maintenance at a network side.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an access method and device. Background technique [0002] In the existing enhanced long-term evolution (Long Term Evolution-Advanced, LTE-A) system, a relay (Relay) technology is introduced, which is mainly used to improve throughput at the cell edge, expand network coverage, and provide group mobility services. [0003] A relay node (Relay Node, RN) is wirelessly connected to the donor node, and connected to the core network through the donor node. The wireless link between the RN and the donor node is called a backhaul link (Backhaul link), and the wireless link between the donor node and the UE it serves and between the RN and the UE it serves is called an access link (Access link). In the LTE-A system, the donor node of the RN is a macro base station (DeNB). There is a single hop between the RN and the macro base station, and there can only be one macro base...
