Fig. 1 is a schematic view of a network switching device according to an embodiment of the present invention, as shown in fig. 1. The base station establishes communication connection with the mobile terminal in the communication range, the base station sends a radio resource control connection reconfiguration message to the mobile terminal, and the mobile terminal can acquire the radio resource control connection reconfiguration message sent by the base station; the mobile terminal performs cell measurement on the first cell according to a cell measurement request in the radio resource control connection reconfiguration message to obtain a measurement result, sends the measurement result to the base station, and the base station generates a radio resource control release message according to the measurement result and sends the radio resource control release message to the mobile terminal; and the mobile terminal disconnects the connection with the second network according to the radio resource control release message and connects the first cell to be connected.
The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.
As shown in fig. 2, the specific flow of the network switching method may be as follows:
201. and when the mobile terminal is in a mode that the first network is closed and the second network is connected, acquiring a radio resource control connection reconfiguration message sent by the base station.
In this embodiment of the present application, the first network is set to be a 5G network, the second network is set to be a 4G network, and the base station is an LTE anchor station. Namely, the mobile terminal is in a mode that the 5G network is closed and is connected with the 4G network, namely, the mobile terminal is in an LTE mode, at the moment, the base station issues a radio resource control (Radio Resource Control, RRC) connection reconfiguration message, and the mobile terminal acquires the RRC connection reconfiguration message sent by the base station.
Before the mobile terminal is in LTE mode, i.e. before the existing 5G power saving policy is triggered, if the current environment is conditional, the mobile terminal can register on the SA network, the mobile terminal will register normally. The method comprises the following specific steps: and the mobile terminal initiates a cell registration request to the independent networking cell, and if the mobile terminal is successfully registered with the target independent networking cell, the registration information of the target independent networking cell is recorded, wherein the registration information comprises identification information and frequency point information of the target independent networking cell. The recording of the registration information of the target independent networking cell may also be the marking of the target independent networking cell. The Standalone networking mode (SA) refers to a newly created 5G network, and includes a new base station, a backhaul link, and a core network.
202. And if the radio resource control connection reconfiguration message contains a cell measurement request of the first network, carrying out cell measurement on the first cell based on the cell measurement request to obtain a measurement result, wherein the measurement result comprises a target first cell meeting a preset reporting condition.
In this embodiment, after receiving the RRC connection reconfiguration message, the mobile terminal determines whether the RRC connection reconfiguration message includes a cell measurement request for the first network. If the RRC connection reconfiguration message includes a cell measurement request of the first network, that is, includes a cell measurement request of the 5G network, the mobile terminal performs cell measurement on the first cell based on the cell measurement request, to obtain a measurement result. The first cell is an NR cell.
The step of performing cell measurement on the first cell based on the cell measurement request specifically includes: determining a target first cell meeting preset reporting conditions from the first cells; and if the target first cell belongs to the target independent networking cell, generating a measurement result based on the target first cell. And acquiring Reference Signal Received Power (RSRP) of the first cell, and determining the first cell with the reference signal received power larger than a power reporting threshold value as a target first cell. For example, RSRP measurement is performed on the NR neighbor cell, if there is a target NR cell satisfying the RSRP reporting threshold in the NR neighbor cell, and at the same time, the target NR cell is also one of the marked target SA cells, that is, a measurement result is generated based on the target NR cell. The target first cell meeting the preset reporting condition, namely the NR cell with the reference signal receiving power larger than the power reporting threshold value.
In this embodiment, after acquiring an RRC connection reconfiguration message issued by a base station, if it is determined that the RRC connection reconfiguration message includes B1 measurement signaling, a first cell measurement request is generated based on the B1 measurement signaling, where the B1 measurement signaling includes a power reporting threshold of Reference Signal Received Power (RSRP). The B1 measurement signaling is a signaling sent by the source access network device to the mobile terminal, where the signaling is used to instruct the mobile terminal to measure the signal quality of the neighboring cell.
In this embodiment, in the process of performing cell measurement on the NR cell, a preset measurement time T and a target measurement frequency N are set, where the maximum measurement frequency is N times in the preset measurement time T. That is, before obtaining the measurement result, the terminal obtains the measurement times of performing cell measurement on the first cell, and determines that the measurement times in the preset time are not greater than the target measurement times. The target measurement times are generally not more than 3, so that the excessive measurement times are avoided.
203. And sending the measurement result to the base station so that the base station generates a radio resource control release message according to the measurement result, wherein the radio resource control release message comprises a first cell to be connected in the target first cell.
In the embodiment of the application, after the terminal obtains the measurement result, the measurement result is sent to the base station, that is, the information of the NR cell meeting the preset reporting condition is sent to the base station. The base station generates a Radio Resource Control (RRC) release message after receiving the measurement result, wherein the RRC release message includes a first cell to be connected among the target first cells. For example, if only one target NR cell meeting the preset reporting condition exists in the measurement result received by the base station, generating an RRC release message directly according to the target cell; if the target NR cells meeting the preset reporting condition in the measurement result received by the base station are multiple, selecting one NR cell to be connected from the multiple target NR cells, and generating an RRC release message based on the information of the NR cell to be connected, wherein the NR cell to be connected is the NR cell to be connected by the next mobile terminal.
204. And acquiring a radio resource control release message sent by the base station, disconnecting the connection with the second network based on the radio resource control release message, and connecting the first cell to be connected.
In the embodiment of the application, the mobile terminal acquires the RRC release message sent by the base station, and disconnects the connection with the second network and connects the first cell to be connected according to the notification information in the RRC release message. For example, if the RRC release message acquired by the mobile terminal indicates to connect to NR cell 1, the mobile terminal releases the connection to the 4G network and registers directly to NR cell 1.
And if the first cell meeting the preset reporting condition does not exist in the process of carrying out cell measurement on the NR cell by the mobile terminal, the connection with the second network is maintained. That is, the mobile terminal does not report measurement information to the base station and remains connected to the 4G network.
And if the mobile terminal is connected to the 5G cell of the non-independent networking, disconnecting the connection of the 5G cell of the non-independent networking and only keeping connection with the 4G network under the condition that the first cell meeting the preset reporting condition does not exist.
Referring to fig. 3, fig. 3 is a flow chart of another network switching method according to an embodiment of the invention. When the UE does not trigger the existing power saving strategy, the UE registration is normal, namely if the current environment is conditional and can register with the SA network, SA is normally registered. At this time, before the power saving strategy is validated, the registered SA cell and the frequency point are recorded, namely, the SA cell which is successfully registered is marked. As shown in fig. 3, after the power saving policy is validated, the UE is in LTE mode, and if the RRC connection reconfiguration message issued by the network includes B1 measurement signaling, an NR neighbor measurement request is generated based on the B1 measurement signaling. And (3) measuring N (N < = 3) times at most in the time T, if the preset reporting condition is met, namely, the reporting threshold of the Reference Signal Received Power (RSRP) of the corresponding NR cell (which simultaneously contains the previously marked SAPCI cell) is met, reporting the B1 measurement report of the 5G neighbor cell to the network, and after the network receives the report, releasing LTE by sending an RRC release message, directly registering on SA, otherwise, not reporting the measurement information, and keeping the UE on the LTE. The embodiment of the invention can solve the problem that the mobile terminal fails to switch from LTE to SA after the 5G power saving strategy is effective.
In order to better implement the above method, the embodiment of the present invention may further provide a network switching apparatus, where the network switching apparatus may be specifically integrated in a network device, and the network device may be a device such as a mobile terminal.

I.e. the mobile terminal is in a mode in which the 5G network is closed and connected to the 4G network, i.e. the mobile terminal is in LTE mode, at this time, the acquiring unit 301 of the mobile terminal acquires the RRC connection reconfiguration message sent by the base station.

If the RRC connection reconfiguration message includes a cell measurement request of the first network, that is, includes a cell measurement request of the 5G network, the measurement unit 302 of the mobile terminal performs cell measurement on the first cell based on the cell measurement request, to obtain a measurement result.

And a sending unit 303, configured to send the measurement result to the base station, so that the base station generates a radio resource control release message according to the measurement result, where the radio resource control release message includes a first cell to be connected in the target first cell.
For example, after the terminal obtains the measurement result, the transmitting unit 303 transmits the measurement result to the base station, that is, transmits information of the NR cell that satisfies the preset reporting condition to the base station. The base station generates a Radio Resource Control (RRC) release message after receiving the measurement result, wherein the RRC release message includes a first cell to be connected among the target first cells.
(4) Connection unit 304
