Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for frequency point switching.
Background
The network sharing refers to a method that different operators share high mobile network deployment cost in a network deployment stage, and the network sharing can greatly improve the utilization rate of the network. The need for network sharing originates in europe, mainly from expensive license plate fees and government regulatory requirements for 3G network coverage. Network sharing provides a method for sharing network deployment cost and rapidly deploying for operators, and along with the development of network sharing application, the method has requirements in developed countries and developing countries. In the LTE (Long Term Evolution ) phase, the current situation that the frequency band is too fragmented injects new activity to the network sharing in the LTE era, and in addition to the factors such as the pressure of the operator in the aspect of capital, the network sharing becomes an important solution for the operator to quickly develop services, reduce the operation cost, and fully utilize spectrum resources.
When the network is shared and deployed, due to the range of a shared area, the transformation/deployment rhythm of the shared network and the like, a boundary area between the shared network and a non-shared network is bound to appear. In this case, when the UE not serving as the network frequency point of the operator moves from the shared network to the unshared network, the UE needs to be switched to the network serving as the network frequency point of the operator, that is, the UE cannot perform co-frequency combining, and needs to perform inter-frequency switching, so that co-frequency interference exists.
As shown in fig. 1, operator a and operator B deploy network sharing in area X, and separately establish networks in other areas. Operator a has frequency point f1, operator B has frequency point f2, in a shared area, operators a and B jointly build/deploy a network, share frequency points of base stations f1 and f2 (same Band with different carriers, or different bands with different carriers), and users of operators a and B can use frequency points f1 and f 2. In a non-shared area, operators A and B independently build/deploy networks, the base station of the operator A is a frequency point f1, the base station of the operator B is a frequency point f2, users of the operator A can only use the frequency point f1, and users of the operator B can only use the frequency point f 2. For example, when a user of an operator B is located at a frequency f1 frequency point in a shared area and moves towards a non-shared area, at a boundary between the shared area and the non-shared area, because the user of the operator B needs to switch to a frequency f2 frequency point of a non-shared base station of the operator B through a pilot frequency, the user may be subjected to co-frequency interference caused by a frequency f1 frequency point of the non-shared base station of the operator a, and particularly when the distance between the non-shared base station of the operator B is relatively long and the distance between the non-shared base station of the operator a is relatively short, the co-frequency interference may be strong, which may seriously affect service performance of the user, and may even cause a call drop of.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
Example 1
This embodiment provides a frequency point switching method, which may be implemented by a base station side, and fig. 2 is a flowchart of the frequency point switching method according to embodiment 1 of the present invention, and as shown in fig. 2, the method includes the following processing:
step 201: configuring a frequency point priority switching band;
step 202: when the user equipment enters a preset frequency point priority switching band, the user equipment is triggered to switch the used frequency point according to the preset frequency point priority in the frequency point priority switching band, wherein the frequency point priority switching band is arranged in a network sharing area within a preset distance from a network non-sharing area.
Further, on the basis of the step 201, the step may specifically include:
before triggering user equipment to switch the used frequency points according to the preset frequency point priority in the frequency point priority switching band, dividing the frequency point priority switching band of the PLMN according to the network sharing area and the non-network sharing area of each network operator;
configuring a PLMN frequency point priority switching list for base stations in each frequency point priority switching band, wherein the frequency point priority switching list comprises: and switching the frequency points available for the user equipment in the band and the priority of the frequency points in the frequency point priority.
The triggering of the user equipment to switch the frequency points used by the user equipment according to the priority of the frequency points preset in the priority switching band may include:
and switching the user equipment to the frequency point with the highest priority in the frequency point priority switching list according to the frequency point priority switching list of the PLMN currently used by the user equipment.
In this embodiment, when the user equipment enters the frequency point priority switching zone, it may be that the user equipment initiates initial access, RRC connection reestablishment, or switches frequency points across the base station in the frequency point priority switching zone, the base station finds that the user equipment enters the frequency point priority switching zone, and then triggers the user equipment to switch the frequency points used by the user equipment according to the frequency point priority preset in the frequency point priority switching zone: when the user equipment initiates initial access, RRC connection reestablishment or cross-base station switching of frequency points in a frequency point priority switching band, according to a frequency point priority switching list of a PLMN currently used by the user equipment, the user equipment is determined to be switched to the frequency point with the highest priority in the frequency point switching list after the user equipment initially accesses, the RRC connection reestablishment or the cross-base station switching of the frequency points.
Further, in this embodiment, triggering the user equipment to switch the frequency point used by the user equipment according to the frequency point priority preset in the frequency point priority switching band may specifically include:
if the frequency point where the user equipment is currently located is in a frequency point priority switching list preset by the PLMN currently used by the user equipment, the user equipment does not need to be triggered to switch the currently used frequency point;
and if the frequency point where the user equipment is currently located is not in the frequency point priority switching list preset by the currently used PLMN, triggering the user equipment to switch to the frequency point with the highest priority in the frequency point priority switching list.
In this embodiment, a frequency point priority switching band is introduced into a boundary area between a network sharing area and a network non-sharing area, when a user moves to the area from the network sharing area or the user initiates access in the area, a network side switches the user to a frequency point of an operator according to a preset frequency point priority list of a PLMN, and when the user moves from the network sharing area to the non-sharing area, the problem of co-frequency interference of the network sharing boundary area to the user is avoided.
Example 2
In this embodiment, more technical details are disclosed on the basis of the comparison document 1 to further describe the frequency point switching method provided by the present invention.
As shown in fig. 3. The operator A and the operator B deploy network sharing in the area, and establish network separately in other areas. Operator a has frequency point f1, operator B has frequency point f2, in a network sharing area, operators a and B jointly build/deploy a network, share frequency points of base stations f1 and f2, and users of operators a and B can use frequency points f1 and f2 (different carriers in the same Band or different carriers in different bands) in the network sharing area. In a network unshared area, operators A and B independently build/deploy networks, a base station of the operator A is a frequency point f1, a base station of the operator B is a frequency point f2, in the unshared area, users of the operator A can only use the frequency point f1, and users of the operator B can only use the frequency point f 2. For example, when a user of an operator B is at a frequency point f1 in a shared area and moves to a non-shared area, and moves to a frequency point priority switching band, the network switches the user of the operator B to the frequency point f2 in time, and the subsequent users of the operator B switch to the non-shared network of the operator B in a network sharing boundary area in a same frequency switching manner, so that the problem of same frequency interference of the network sharing boundary area to the user of the operator B is avoided.
The above process is further described with reference to fig. 4 and more sophisticated steps, fig. 4 is a flowchart of a frequency point switching method provided in embodiment 2 of the present invention, and as shown in fig. 4, the method includes the following steps:
the first step is as follows: when a shared network is deployed and reconstructed, dividing boundary areas of a network sharing area and a network non-sharing area into frequency point priority switching bands according to the ranges of the network sharing area and the network non-sharing area;
the second step is that: and when the network sharing mode is opened, adding parameters of the PLMN level frequency point priority switching list in the LTE network management configuration system. After the parameter network management is configured, after an eNB (base station) system in a frequency point priority switching band is successfully started, parameters of a PLMN level frequency point priority switching list configured by the network management are synchronized into a database of the eNB in the frequency point priority switching band to serve as reference basis for frequency point priority switching;
the third step: when UE (user equipment) initiates initial access, or RRC connection reestablishment, or cross-eNB switching, an eNB in a frequency point priority switching band judges whether UE is switched to a frequency point with high priority after successful UE initial access, RRC connection reestablishment and cross-eNB switching according to a PLMN currently providing service for the UE and a frequency point priority switching list configured in a background and corresponding to the current service PLMN of the UE;
the fourth step: and if the current frequency point of the UE is included in the corresponding PLMN frequency point priority switching list configured by the network management, the eNB in the frequency point priority switching band does not trigger the UE switching. Otherwise, the eNB in the frequency point priority switching band can screen the candidate different-frequency switching target cell which is in the same coverage or inclusion relation with the cell where the UE is currently located and supports the current service PLMN of the UE, and actively initiates the switching of the UE to the different-frequency cell with high priority.
The fifth step: and the UE executes the pilot frequency switching process in the eNB in the frequency point priority switching band and switches to the pilot frequency cell with high priority.
And a sixth step: when the subsequent UE continues to move to the unshared area, the UE triggers an equal-frequency switching process according to the current serving PLMN and the equal-frequency measurement report, and switches to the unshared eNB equal-frequency adjacent area, so that the problem of equal-frequency interference of a network sharing boundary area is avoided.
Compared with the prior art, the method provided by the embodiment avoids the problem of co-channel interference when the UE moves from the shared network to the non-shared network area in the boundary area of the shared and non-shared areas in the network sharing scene, and the solution does not need to modify a 3GPP protocol, is simple and easy to operate, and is suitable for other systems with similar problems.
Example 3
The embodiment further explains the frequency point switching method provided by the invention through a specific application scene.
In this embodiment, as shown in fig. 5, eNB1 is a base station in the cyber-shared area, eNB2 is a base station in the cyber-shared area boundary frequency point priority handover band, and eNB3 is a base station in the non-cyber-shared area. Wherein, f1 and f2 may be different carriers of the same Band, or different carriers of different bands.
Based on the aspect of configuring the frequency point priority switching list at the PLMN level, after the network sharing mode is opened, the parameters of the frequency point priority switching list at the PLMN level are configured in the LTE network management configuration system, and after the eNB2 is started, the parameters are synchronized into the database of the eNB2 in the frequency point priority switching band through the network management.
Based on the frequency point configuration aspect, the base station of the operator a is the f1 frequency point, the base station of the operator B is the f2 frequency point, the operator a and the operator B share the frequency points f1 and f2 in the shared area, and the UE is the user of the operator B and resides in the frequency point f1 in the network shared area. And the background configures the frequency point in the frequency point priority list of the operator A as f1, and the frequency point in the frequency point priority list of the operator B as f 2. Thus, eNB1 supports f1 and f2 frequency bins, eNB2 supports f1 and f2 frequency bins, and eNB3 supports f2 frequency bins.
In a network sharing scenario, a UE camps on a f1 frequency point cell in a network sharing border area eNB2 to initiate initial access, and the specific flow is as shown in fig. 6.
The UE resides in a f1 frequency point cell, and requests the eNB2 to establish RRC Connection through an RRC Connection Request message;
the RRC connection establishment is completed between the UE and the eNB 2;
establishing an Initial Context Setup process between the UE and the network side;
the eNB2 judges that the current frequency point of the UE is f1 according to the current serving PLMN of the UE and a switching frequency point list corresponding to the current serving PLMN of the UE and configured by a background, and the current frequency point is inconsistent with the frequency point list f2 in the frequency point priority switching list of the serving PLMN, and then the eNB2 actively triggers the UE to switch to f 2;
the eNB initiates an intra-station inter-frequency switching process, issues an RRC Connection Reconfiguration switching command to the UE, and instructs the UE to switch to an f2 frequency adjacent cell of the eNB 2;
after the UE is switched to the f2 frequency adjacent cell of the eNB2, the eNB2 is informed through an RRC Connection Reconfiguration Complete message;
and when the follow-up UE continues to move the eNB3 to the unshared eNB, the UE triggers an f2 same frequency switching process according to the current service PLMN and the same frequency measurement report, and switches to an unshared eNB3 same frequency f2 adjacent cell.
Example 4
The embodiment further explains the frequency point switching method provided by the invention through a specific application scene.
In a network sharing scenario, the UE performs data service from a cell on the f1 frequency point of the eNB1 in the network sharing area, and moves to the eNB2 in the network sharing border area, where the specific flow is shown in fig. 7.
The UE normally resides in a cell on the frequency point f1 of the eNB1 in the network sharing area, data service connection is established, and the UE moves towards the direction of the coverage area of the eNB2 in the frequency point priority switching band;
the UE requests the eNB1 to switch to the f1 co-channel cell of the eNB2 through a Measurement Report Measurement message;
the eNB1 indicates that the UE is switched to the f1 co-frequency cell of the eNB2 in the frequency point priority switching band, and the UE is successfully switched to the f1 co-frequency cell of the eNB 2;
the eNB2 judges that the current frequency point of the UE is f1 according to the current serving PLMN of the UE and a switching frequency point list corresponding to the current serving PLMN of the UE and configured by a background, and the current frequency point is inconsistent with the switching frequency point list f2 of the serving PLMN, and the eNB2 actively triggers the UE to switch to f 2;
the eNB initiates an intra-station inter-frequency switching process, issues an RRC Connection Reconfiguration switching command to the UE, and instructs the UE to switch to an f2 frequency adjacent cell of the eNB 2;
after the UE is switched to the f2 frequency adjacent cell of the eNB2, the eNB2 is informed through an RRC Connection Reconfiguration Complete message;
and when the follow-up UE continues to move the eNB3 to the unshared eNB, the UE triggers an f2 same frequency switching process according to the current service PLMN and the same frequency measurement report, and switches to an unshared eNB3 same frequency f2 adjacent cell.
