For example, taking fig. 1 as an example, cell 1 and cell 2 are independent cells, and the central frequency points are different, that is, the inter-frequency cell, the core Network 1 Public Land Mobile Network (PLMN) ID is set to be 1, for example, and the core Network 2PLMN ID is set to be 2, for example. Cell 2 supports eRANSharing (radio access network sharing) and has simultaneous access to core network 1 and core network 2. Thus, the users in cell 1 can access cell 2 and share the radio resources of cell 2. The requirement in some projects is that some users of cell 1 can share the radio resources of cell 2, and some users cannot share, and only remain in cell 1. Existing cell 2 forces the UE1 user to reselect to cell 1 through a reselection action.

If the user is always in the connected state, the cell reselection action cannot be implemented, so that the user who is forbidden to access the cell temporarily stays in the cell, for example, part of the users in the above cell 1 temporarily stays in the cell 2.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In a communication system, after a UE is powered on, a cell is always selected to camp on, and then service establishment is initiated on the selected cell or a service establishment request from a network is received to obtain a wireless service. For example, taking fig. 1 as an example, cell 1 and cell 2 are independent cells, and the central frequency points are different, that is, the inter-frequency cells, the PLMN ID of core network 1 is set to 1, for example, and the PLMN ID of core network 2 is set to 2, for example. Cell 2 supports eRANSharing (radio access network sharing) and has simultaneous access to core network 1 and core network 2. Thus, the users in cell 1 can access cell 2 and share the radio resources of cell 2. A requirement in some projects is that some users of cell 1 may share the radio resources of cell 2, e.g., UE2 and UE3 users, and some users may not share, leaving only cell 1, e.g., UE1 users. Existing cell 2 forces the UE1 user to reselect to cell 1 through a reselection action.
However, cell reselection is a procedure for IDLE state user cell selection (the relevant protocol specifies that cell reselection is to be performed in IDLE state). If the user is always in the connected state, the cell reselection action cannot be implemented, so that the user who is forbidden to access the cell temporarily stays in the cell, for example, part of the users in the above cell 1 temporarily stays in the cell 2.
Therefore, in view of the above problems, the present application provides a cell handover method, which enables a user who is forbidden to access a cell to perform cell handover in a connected state by forced handover measurement, so as to solve the problem that the user who is forbidden to access the cell stays in the cell temporarily because the cell reselection operation cannot be implemented if the user is always in the connected state.
The cell handover method provided by the present application may be applied to a cell handover system shown in fig. 2, where the system includes a serving cell base station 10 and a user equipment 20.
In a specific implementation process, a serving cell base station 10 receives an access request of user equipment; judging whether the user equipment 20 is a user equipment prohibited from accessing according to the access request; if yes, sending a measurement control message to the ue 20, where the measurement control message includes a frequency point list of a cell that the ue 20 allows to access, a GAP parameter, and a pilot frequency handover measurement parameter, and the cell that the ue allows to access and the serving cell are pilot frequency cells. The user equipment 20 receives the measurement control message, performs pilot frequency test according to the frequency point list, GAP parameters, and pilot frequency handover measurement parameters of the cell to which the user equipment 20 allows access, initiates a pilot frequency handover procedure after conditions are met, and sends a handover request to the serving cell base station 10. The serving cell base station 10 receives the handover request and performs cell handover according to the handover request. The serving cell may be any one or more cells, or may also be a type of cell, for example, a cell to which part of users of the cell 1 are prohibited from accessing, which is not particularly limited in this application.
It should be understood that the above-mentioned architecture is only an exemplary system architecture block diagram, and in specific implementation, the above-mentioned architecture may be set according to application requirements, for example, the server side may further include a receiving device for receiving information related to the above-mentioned data transmission interval, time upper limit, and the like, so as to meet different application requirements.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

and if the user equipment carries the SPID, determining whether the user equipment is the access-forbidden user equipment or not according to the cell to which the user equipment is forbidden to access and the service cell.
Specifically, if the serving cell is in the cell to which the user equipment is prohibited from accessing, it is determined that the user equipment is prohibited from accessing.

In addition, the frequency point list is different from a frequency point list based on covered pilot frequency switching, so that the switching residence strategy based on the SPID can be controlled to be applied to partial frequency points, and the user mobility is accurately controlled.
For example, the condition may be determined according to inter-frequency handover measurement parameters, such as whether the measurement information and the measurement offset of the event meet the set measurement threshold and the measurement offset of the event.

As can be seen from the above description, in the embodiment of the present application, the serving cell base station monitors whether there is a user equipment access prohibited from being accessed, and if there is a user equipment access prohibited from being accessed, the serving cell base station sends a measurement control message to the corresponding user equipment, so that the user equipment performs a pilot frequency test according to the measurement control message, and after the test meets a condition, initiates a pilot frequency handover procedure, sends a handover request to the serving cell base station, and the serving cell base station performs cell handover according to the handover request, that is, through a forced handover measurement, the user who is prohibited from being accessed to the cell is forced to perform cell handover in a connected state.
