When the communication quality of a first cell in which a terminal is located is increasingly poor, access network equipment of the first cell needs to determine a second cell with better communication quality from a plurality of adjacent cells through measurement data, and then sends a switching command to the terminal, so that the terminal is accessed to the access network equipment of the second cell.

The cell handover method provided in the embodiment of the present application is described in detail below with reference to the cell handover system shown in fig. 1 and the cell handover apparatus shown in fig. 2 (or fig. 3).
Fig. 4 is a flowchart illustrating a cell handover method according to an embodiment of the present application. As shown in fig. 4, the cell handover method is applied to the access network device of the first cell, and for convenience of understanding, the access network device of the first cell is taken as a base station in a 5G network as an example in the embodiment of the present application. The cell switching method includes the following S401-S408.
S401, the base station acquires the network slice identifier of the terminal.
Specifically, when the terminal communicates with the base station, a Protocol Data Unit (PDU) session control is first established. PDU session control is the basic granularity unit of network slicing. After the terminal is successfully registered, the PDU session can be established, and the transmission of service data is realized. The service is carried by PDU session control, and each PDU session control carries a network slice identifier. Multiple PDU session controls may carry the same network slice identity. Since the PDU session control is the basic unit of the network slice, the base station can acquire the network slice identifier of the terminal when establishing the PDU session with the terminal.
S402, the base station acquires a service level agreement of the target network slice type of the first cell.
Specifically, the Service Level Agreement (SLA) refers to an agreement or contract that is agreed by an operator and a client providing a service and is commonly accepted by the operator and the client with respect to quality, level, performance, and the like of the service. Illustratively, the service level agreement established between the terminal and the base station is to transmit 1G uplink traffic and 10G downlink traffic in one period.
Optionally, since the terminal may include a plurality of network slice types, a plurality of service level agreements may be established between the terminal and the base station. Each service level agreement corresponds one-to-one to each network slice type.
Optionally, the service level agreement may be stored in a cloud database of an operator, or may be stored in a database inside the base station, which is not limited in this embodiment of the present application.
Optionally, the base station may perform S401 first, and then perform S402; or executing S402 first and then executing S401; s401 and S402 may also be performed simultaneously; the embodiments of the present application do not limit this.
S403, the base station judges whether the data volume transmitted by the terminal under the target network slice type meets the service level agreement.
Specifically, the base station determines whether the data volume transmitted by the terminal under the target network slice type meets the service level agreement or not according to the network slice identifier of the terminal and the service level agreement of the target network slice type of the first cell. And if the data volume transmitted by the terminal under the target network slice type meets the service level agreement, not executing any operation. If the data volume transmitted by the terminal under the target network slice type does not meet the service level agreement, S404 is executed.
Illustratively, the base station determines that the network slice type of the current service of the terminal is type a, and the service level agreement of the terminal under type a is: and transmitting the 1G uplink flow and the 10G downlink flow in a preset time period. When the base station determines that the terminal has transmitted the 1G uplink traffic and the 10G downlink traffic in the type a, it determines that the data volume transmitted by the terminal in the target network slice type does not satisfy the service level agreement, and then S404 is executed. Otherwise, no operation is performed.
S404, the base station acquires the network slice type supported by each adjacent cell in a plurality of adjacent cells.
And the adjacent cells are adjacent cells of the first cell.
Specifically, when the base station determines that the data volume transmitted by the terminal in the target network slice type does not satisfy the service level agreement, if the base station still keeps communicating with the base station of the first cell, the base station may decrease the communication resources allocated to the terminal, thereby affecting the communication quality of the terminal. Under the condition, the base station adds the base station of the adjacent cell meeting the requirement of the terminal, and switches the terminal to the base station of the adjacent cell, so that the communication quality of the terminal is not affected, and the communication quality of the terminal is improved.
However, in the prior art, the base station usually acquires data of all neighboring cells, and determines the base station corresponding to the optimal cell according to the data of all neighboring cells. This method is time consuming and labor intensive and inefficient. In the application, when the base station determines that the data volume transmitted by the terminal under the target network slice type does not meet the service level agreement, the network slice type supported by each adjacent cell in a plurality of adjacent cells is obtained first.
S405, the base station determines at least one third cell corresponding to the target network slice type in the network slice types supported by each adjacent cell.
After the network slice type supported by each adjacent cell in the plurality of adjacent cells is obtained, the base station determines at least one third cell corresponding to the target network slice type according to the network slice type supported by each adjacent cell. In this case, the base station does not need to perform subsequent data measurement on the cell which does not correspond to the target network slice type, thereby improving the efficiency of data measurement.
Illustratively, referring to fig. 1, as shown in fig. 5, the base station 1 is a base station of a first cell. The base station 2 is a base station of the second cell. The base station 3 is a base station of a third cell. The terminal is located in the first cell at the present moment and the terminal is connected to the base station 1 through the communication network. The base station 1 of the first cell supports a first network slice type and a second network slice type. The base station 2 of the second cell supports only the first network slice type. The base station 3 of the third cell supports only the second network slice type. When the terminal has a service only in the first network slice type, if the data volume transmitted by the terminal in the first cell does not satisfy the service level agreement, at this time, the base station 1 only needs to perform data measurement on the base station 2, and does not need to perform data measurement on the base station 3, thereby improving the efficiency of data measurement.
S406, the base station acquires the communication quality of at least one third cell.
After determining at least one third cell corresponding to the target network slice type in the network slice types supported by each adjacent cell, the at least one third cell meets the network slice type of the terminal service, so that the base station obtains the communication quality of the at least one third cell.
S407, the base station determines that the cell corresponding to the communication quality meeting the preset condition in the communication quality of the at least one third cell is the second cell.
After the communication quality of the at least one third cell is obtained, the base station determines that the cell corresponding to the communication quality meeting the preset condition in the communication quality of the at least one third cell is the second cell. And the second cell is the cell to be switched by the terminal.
Illustratively, when the base station determines that the network slice type of the current service of the terminal is the type a, the base station acquires m cells corresponding to the supported type a from a plurality of adjacent cells as a third cell. The other cells do not need to continue measuring data. Then, the communication quality of each of the m third cells is acquired. For example, the communication quality of cell a is to transmit 5M downlink data per second, the communication quality of cell B is to transmit 3M downlink data per second, the communication quality of cell C is to transmit 1M downlink data per second, and the terminal preset condition is that 4M downlink data per second needs to be transmitted. Then the cell a is determined as the cell corresponding to the communication quality meeting the preset condition, that is, the cell a is determined as the second cell.
S408, the base station sends the indication information to the terminal.
The indication information is used for indicating the terminal to access the access network equipment of the second cell.
The embodiment of the application provides a cell switching method, which comprises the following steps: the method comprises the steps that access network equipment of a first cell acquires a service level protocol of a target network slice type of the first cell, if the data volume transmitted by a terminal under the target network slice type does not meet the service level protocol, a second cell supporting the target network slice type is determined, and indication information used for indicating the access network equipment of the terminal to access the second cell is sent to the terminal.
In the invention, the access network equipment of the first cell indicates the terminal to access the access network equipment of the second cell supporting the target network slice type when the access network equipment of the first cell determines that the data volume transmitted by the terminal under the target network slice type does not meet the service level protocol according to the service level protocol of the target network slice type. Compared with the prior art, the method and the device can directly switch the cell accessed by the terminal according to the network slice type, and solve the problem that the access network equipment cannot indicate the terminal to access the access network equipment of the cell meeting the terminal requirement according to the network slice technology.

Whether a function is performed as hardware or computer software drives hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present invention.
In the embodiment of the present application, the cell switching apparatus may be divided into the functional modules according to the above method example, for example, each functional module may be divided according to each function, or two or more functions may be integrated into one processing module. The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode. Optionally, the division of the modules in the embodiment of the present application is schematic, and is only a logic function division, and there may be another division manner in actual implementation.
