Problems solved by technology

[0006] During the research and practice of the prior art, the inventors of the present invention found that in the prior art, when the terminal (User Equipment, UE) switches from eNB to RN, the terminal can obtain the identity of the RN through interaction with the RN identify (RN_ID), and report the RN_ID to the network side, the network side determines the RN to which the terminal is to switch to through the RN_ID, but the network side cannot determine the control base station DeNB of the relay station, so the handover request message cannot be sent to the correct DeNB, so that the whole handover process cannot be carried out normally

Embodiment 1

[0057] Embodiment 1. A handover control method, the flow is as follows figure 2 shown, including:

[0058] A1, acquiring the relay station identifier corresponding to the target cell to which the terminal is handed over;

[0059] A2, according to the identifier of the relay station, obtain the identifier of the control base station corresponding to the relay station;

[0060] In the embodiment of the present invention, the routing relationship between the relay station and the control base station is preset, and after the terminal obtains the identifier of the relay station, the corresponding control base station can be obtained according to the routing relationship.

[0061] A3, sending a handover control request to the control base station according to the identifier of the control base station;

[0062] A4, the controlling base station notifies the relay station to perform access control on the terminal.

[0063] The embodiment of the present invention identifies the co...

Embodiment 2

[0064] Embodiment 2, a switching control method, the flow chart is as follows image 3 shown, including:

[0065] B1, the base station receives the target cell measurement report reported by the terminal; the target cell measurement report includes: target cell identity;

[0066] In this embodiment, the target cell identifier may be a global cell identifier (E-UTRAN Cell Global Identifier, ECGI) or a physical cell identifier (Physical Cell ID, PCI);

[0067] B2, the base station obtains the relay station identifier corresponding to the target cell according to the target cell identifier;

[0068] Since the ECGI contains the relay station identifier (generally the first 20 digits of the ECGI are the identifier of the base station or relay station to which the cell belongs), if the target cell identifier is ECGI, the base station can obtain the relay station identifier in the ECGI by parsing the ECGI.

[0069] Since the PCI does not include the relay station identifier, if the...

Embodiment 3

[0093] Embodiment 3, a switching control method, the flow chart is as follows Figure 5 shown, including:

[0094] D1, the base station receives the target cell measurement report reported by the terminal; the target cell measurement report includes: target cell identity;

[0095] D2, the base station obtains the relay station identifier corresponding to the target cell according to the target cell identifier;

[0096] In this embodiment, the relay station identification includes: the identification of the control base station of the relay station and the extension identification, and the extension identification is used to distinguish the relay stations under the same control base station; it can be understood that the relay station is powered on within the coverage of the control base station or moves to the coverage of the control base station After being within the range, the control base station assigns a relay station identifier to the relay station.

[0097] In this e...

Abstract

The invention discloses a switching control method, a switching control device and a communication system. According to an embodiment, a control base station (DeNB) of a relay station is identified according to a corresponding relation between the established relay station and the established control base station, so a switching request message is enabled to route to a correct DeNB and finally reaches RN, and thereby switching from a terminal to a relay station control district is enabled to carry out normally.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a switching control method, device and communication system. Background technique [0002] The International Telecommunication Union Radio (ITU-R) named the Beyond Third Generation in mobile communication system (B3G) as the International Mobile Telecommunications Advanced System (IMT-Advanced). On the one hand, IMT-Advanced puts forward high requirements on system capacity; on the other hand, the large-bandwidth spectrum that supports the high capacity of IMT-Advanced can only be found in higher frequency bands, and the path loss and penetration loss of high-frequency bands are relatively high. Large and difficult to achieve good coverage. [0003] In order to meet the requirements of IMT-Advanced for system capacity and high coverage, in the prior art, the introduction of relay technology is proposed to improve system capacity and coverage. In traditional network...
