Specific embodiment

To make purpose, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is The a part of embodiment of the present invention, rather than the embodiment of whole.Based on the embodiment in the present invention, those of ordinary skill in the art The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.

Fig. 1 is schematic flow sheet of the present invention based on the cell switching method embodiment one of white frequency spectrum.In the present embodiment, cut Change destination node carries out Signalling exchange with data base, and to obtain white spectrum authorization message is obtained.As shown in figure 1, should be based on white frequency The cell switching method of spectrum comprises the following steps：

S101：Receive the handover request message that switching source node sends.

When needing cell to switch, switch destination node and receive the handover request message that switching source node sends.

S102：White spectrum authorization is sent to data base obtain message.

Switching destination node needs for white spectrum authorization acquisition message to be sent to data base, and the white spectrum authorization obtains message For to the right to use of the white frequency spectrum of database request, it at least to include a kind of following parameter：Source node identification, user equipment mark Know symbol, destination node marking symbol, user equipment RF index, antenna parameter, working frequency points, maximum transmission power, band internal power Spectrum density, the white spectrum authorization obtains message.

S103：The authorization response message of receiving data storehouse feedback.

Switching destination node receives the mandate of the white spectrum information that the carrying permission user equipment of Database Feedback is used and rings Message is answered, Jing after the confirmation of data base, user equipment can just be linked into new cell.The authorization response message at least include with Next kind of parameter：User equipment usable spectrum list, each frequency range can be with peak power, maximum available power spectrum densities, whether Support carrier aggregation, database identifier, white spectrum device identifier, spectrum information enrollment results index symbol etc..

In S102 and S103, the exchange of signaling between switching destination node and data base, such as white spectrum authorization acquisition message, Authorization response message etc., may be by spectrum manager（Spectrum manager, hereinafter referred to as SM）, Mobility Management Entity （Mobility management entity, hereinafter referred to as MME）, PDN Gateway（packet data network-gate Way, hereinafter referred to as P-GW）, Service Gateway（Service-gate way, hereinafter referred to as S-GW）One or more Deng entity are entered Row forwarding.

In the present embodiment, Wireless Telecom Equipment is broadly divided into node device and the class of user equipment two, and node device belongs to Master WSD, user equipment belongs to slave WSD；User equipment is carrying out cell switching（handover）When, it will change Access node, is switched to the working frequency points of new cell, power these information and is likely to become.Therefore, access in user equipment Before new cell, need the parameter notification database such as the node equipment identification of new cell, working frequency points, power, to obtain Obtain the mandate of white frequency spectrum resource used in cell after handover.

Cell switching method based on white frequency spectrum provided in an embodiment of the present invention, when cell switching is carried out, switches target Node receives the handover request message that switching source node sends, and sends white spectrum authorization to data base and obtains message and receiving data The authorization response message of storehouse feedback, to obtain the permission of data base, strict the using for regulation dialogue frequency spectrum that have followed specifies, makes Obtain user equipment to enter after new cell, can be with legal using white frequency spectrum resource.

Fig. 2 is schematic flow sheet of the present invention based on the cell switching method embodiment two of white frequency spectrum.In the present embodiment, cut Change destination node and send white frequency spectrum renewal request message to data base.As shown in Fig. 2 the cell switching method of white frequency spectrum should be based on Comprise the following steps：
