Embodiment 1

[0064] figure 1 The method flowchart provided for the embodiment of the present invention, such as figure 1 As shown, the method may include the following steps:

[0065] Step 101: the RN sends the cell number information of the RN to the RN OAM entity.

[0066] In this step, the RN may send the requested number of cells to the RN OAM entity, or send the number of cells the RN is preparing to generate or the maximum number of cells that the RN can support or the hardware capability of the RN to the RNOAM entity.

[0067] At the same time as step 101, the RN may communicate with the EPC via the eNB. At this time, the cell data information sent by the RN to the RN OAM entity is physically sent to the RN OAM entity via the eNB; or, the RN may also communicate with the EPC via the DeNB, At this time, the cell number information sent by the RN to the RN OAM entity is physically sent to the RN OAM entity via the DeNB.

[0068] In addition, it should be noted that this step 101 is...

Embodiment 2

[0092] figure 2 The flow chart of the method provided by Embodiment 2 of the present invention, such as figure 2 As shown, the method may include the following steps:

[0093] Step 201: The RN OAM entity determines the number of cells configured for the RN, and sends information about the number of cells configured for the RN to the RN.

[0094] The method for the RN OAM entity to determine the number of cells configured for the RN may be the method in step 101 and step 102 in the first embodiment.

[0095] If the RN communicates with the EPC via the eNB, the cell number information sent by the RN to the RN OAM entity is physically via the eNB; or, if the RN communicates with the EPC via the DeNB, the cell number information sent by the RN to the RN OAM entity is physically on via DeNB.

[0096] Step 202: RN sends information about the number of cells configured for the RN to the DeNB.

[0097] After receiving the cell number information configured by the RN OAM entity, ...

Embodiment 3

[0118] image 3 The method flowchart provided for the third embodiment of the present invention, such as image 3 As shown, the method may include the following steps:

[0119] Step 301: The RN OAM entity determines the number of cells configured for the RN, and sends information about the number of cells configured for the RN to the DeNB OAM entity.

[0120] The method for the RN OAM entity to determine the number of cells configured for the RN may be the method in step 101 and step 102 in the first embodiment.

[0121] Step 302: The DeNB OAM entity allocates a CI group for the RN according to the received number of cells configured for the RN, and sends the CI group information to the RN OAM entity.

[0122] The DeNB OAM entity determines the number of cells allocated to the RN according to the number of cells received, or according to the number of cells received and the CIs of the cells of the DeNB accessed by the RN and the cells of all the RNs that have accessed the De...

Abstract

The invention provides a method for configuring an evolution cell global identification (ECGI) of a terrestrial radio access network to a relay node(RN), which comprises the steps that: a relay node (RN) operation and maintenance (OAM) entity ensures the cell number which is distributed for the RN and cell identity (CI) group information distributed for each RN cell; each CI in the CI group accesses into the cell of a donor evolution base station (DeNB), wherein all RN cells under the DeNB are sole, and the CI number in the CI group is as the same as the cell number distributed for the RN; and the RN OAM entity configures identification of a public land mobile network (PLMN) for each RN cell, configuring the CI for each RN cell according to the CI group information, and transmitting ECGI information of the RN to the RN. The method is used for configuring the global unique ECGI for the RN, so that the RN can normally work.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for configuring a global identifier of a terrestrial wireless access network evolution cell of a relay node (RN). Background technique [0002] According to the requirements of Advanced International Mobile Telecommunications (IMT-Advanced), the next-generation wireless communication system should meet the transmission characteristics of the highest 1Gbps rate to support various data services that are constantly emerging. In order to meet the requirements of IMT-Advanced, 3GPP has carried out the research of the enhanced long-term evolution system (LTE-Advanced) project. Key technologies of the LTE-Advanced system include multi-antenna enhancement (Enhanced MIMO), carrier aggregation (CA, Carrier Aggregation), relaying (Relaying) and multi-point coordinated transmission (CoMP, Coordinated Multi-point). [0003] Among several key technologies of LT...
