Embodiment 1

[0085] In the GSM communication standard, the two small cells in a cell are respectively small cell A (corresponding to small cell base station A) and small cell B (corresponding to small cell base station B), and the public carrier of small cell A and small cell B ( That is, the common channel) is C0, the dedicated carrier frequency (ie dedicated channel) of small cell A is C1, and the dedicated carrier frequency (ie dedicated channel) of small cell B is C2. When the terminal moves from small cell A to small cell B during voice service, refer to Figure 8 As shown, the detailed intra-cell handover process under the small cell dense networking technology is as follows:

[0086] Step 800: After the coprocessor of the small cell base station determines that the signal strength of the transmission signal sent by the terminal through the dedicated carrier frequency C1 of the small cell base station A is lower than the preset threshold value, it notifies the small cell base station...

Embodiment 2

[0093] In the WCDMA communication system, the two small cells in a cell are respectively small cell A and small cell B, the common scrambling code group 1 (that is, the common channel) of small cell A and small cell B, and the corresponding scrambling code of small cell A Group 2 (dedicated channel), small cell B corresponds to scrambling code group 3 (dedicated channel). refer to Figure 9 As shown, the detailed intra-cell handover process under the small cell dense networking technology is as follows:

[0094] Step 900: After the coprocessor of the small cell base station determines that the signal strength of the transmission signal sent by the terminal through the scrambling code group 2 of the small cell base station A is lower than the preset threshold value, it notifies the small cell base station A to switch the terminal to the common scrambling code group 1.

[0095] When the terminal performs communication services in the small cell A, the terminal accesses the cor...

Abstract

The invention discloses an intra-cell switching method and device under small cellular dense networking. The method comprises the steps that a first small cellular base station receives a first switching request message sent by a small cellular base station coprocessor and switches a terminal from a private channel of the first small cellular base station to a public channel; the small cellular base station coprocessor detects signal intensity of a transmission signal sent by the terminal to each small cellular base station through the public channel; the small cellular base station coprocessor selects the small cellular base station corresponding to the transmission signal with the strongest signal intensity as a second small cellular base station according to a detection result; and the small cellular base station coprocessor switches the terminal from a first small cellular to a second small cellular, so that the terminal is accessed to a core network through a private channel of the second small cellular base station. With the adoption of the technical scheme, the intra-cell switching of the terminal can be realized without large-scale transformation of the existing small cellular dense networking architecture.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an intra-cell handover method and device under dense networking of small cells. Background technique [0002] In the communication system, the macro cellular architecture networking technology is mostly used. In the macro cellular architecture networking technology, one base station is used in a cell, and the air interface resources of all channels cover all ranges in the cell, that is, in the cell using the macro cellular architecture networking technology, any position can use the air interface of any channel resource. [0003] refer to figure 1 Shown is a schematic diagram of channel distribution in the macro-cellular architecture networking technology in the prior art. If a cell using the macro-cellular architecture networking technology includes four channels f0, f1, f2, and f3, within the coverage of the above-mentioned cells, all Any one of the four chann...
