Embodiment 1

[0028] This embodiment provides a frequency point switching method, which can be implemented by the base station side, figure 2 It is a flow chart of the frequency point switching method in Embodiment 1 of the present invention, such as figure 2 As shown, the method includes the following processing:

[0029] Step 201: Configuring frequency point priority switching bands;

[0030] Step 202: When the user equipment enters the preset frequency point priority switching band, trigger the user equipment to switch the frequency point it uses according to the preset frequency point priority in the frequency point priority switching band, wherein the frequency point priority The level switching zone is set in the network sharing area within the preset distance from the network non-sharing area.

[0031] Further, on the basis of the above step 201, this step may specifically include:

[0032] Before switching the preset frequency priority in the band according to the frequency pri...

Embodiment 2

[0042] This embodiment discloses more technical details on the basis of Reference Document 1 to further explain the frequency point switching method provided by the present invention.

[0043] like image 3 shown. Carrier A and Carrier B deploy shared networks in one area, and build separate networks in other areas. Operator A owns frequency point f1, and operator B owns frequency point f2. In the network sharing area, operators A and B jointly build / deploy the network and share base station frequencies f1 and f2. Users of operators A and B are on the network Both frequency points f1 and f2 can be used in the shared area (different carriers in the same band, or different carriers in different bands). In the non-shared network area, operators A and B independently build / deploy the network. The base station of operator A is at frequency f1, and the base station of operator B is at frequency f2. In the non-shared area, the users of operator A only The f1 frequency point can be...

Embodiment 3

[0053] In this embodiment, the frequency point switching method provided by the present invention is further described through specific application scenarios.

[0054] In this example, if Figure 5 As shown, eNB1 is a base station inside the network sharing area, eNB2 is a base station within the boundary frequency point priority switching band of the network sharing area, and eNB3 is a base station not in the network sharing area. Wherein, f1 and f2 may be different carriers of the same Band, or may be different carriers of different Bands.

[0055] Based on the configuration of the PLMN-level frequency point priority switching list, after the network sharing mode is enabled, configure the parameters of the PLMN-level frequency point priority switching list in the LTE network management system, and after eNB2 is started, the parameters are synchronized to the frequency The point priority is switched in the database of the in-band eNB2.

[0056] Based on the configuration of...

Abstract

The invention provides a frequency point switching method and an apparatus thereof. In a network, a same-frequency interference at a boundary of a shared network area and a non-shared network area is high. By using the method and the apparatus of the invention, the above problem is solved. The frequency point switching method comprises the following steps that when user equipment enters into a preset frequency point priority switching band, according to a frequency point priority which is preset in the frequency point priority switching band, a frequency point used by the user equipment to carry out switching is triggered; and the frequency point priority switching band is arranged in the shared network area which has a preset distance with the non-shared network area. By using the scheme of the invention, a same-frequency interference problem of the user equipment which moves towards the non-shared network area from the shared network area is avoided.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a frequency point switching method and device. Background technique [0002] Network sharing refers to a practice in which different operators share high mobile network deployment costs during the network deployment phase, which can greatly improve network utilization. The demand for network sharing originated in Europe, mainly due to expensive license fees and government regulations on 3G network coverage. Network sharing provides operators with a method of apportioning network deployment costs and rapid deployment. With the development of network sharing applications, there is demand in both developed and developing countries. In the LTE (Long Term Evolution, Long Term Evolution) stage, the status quo of too fragmented frequency bands has injected new vitality into network sharing in the LTE era. Coupled with factors such as the pressure on operators' funds, network shari...
