For redirection, due to coverage issues, currently operators choose to reselect Voice over NR (Voice over NR, IMS-based Voice services provided by 5G access networks and core networks) telephony to LTE (Long Term Evolution ) Voice over LTE (Voice over LTE, multimedia subsystem IMS-based Voice services scheme). After a normal User Equipment (UE) sends a call IMS 183Session progress on a New Radio (NR), a base station sends redirection to the UE to enable the UE to initiate a TAU (TA Tracking Area update procedure) to an LTE frequency point, and then attaches the UE to the LTE to perform a VoLTE call. In this case, after the UE sends out the Session Progress, the NR network does not issue RRC (radio resource control) Release (Release), and does not tell which frequency point and cell of LTE the UE needs to switch to. The existing strategy is to wait for a period of time until the UE reports a 5G RLF (radio link failure ), then reselect to LTE, and guarantee the call through EPS Fallback.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
The embodiment of the invention provides a network switching method, a network switching device and a mobile terminal. The mobile terminal of the embodiment of the invention can be a mobile phone, a tablet personal computer, a notebook computer and other devices. The network switching method comprises the following steps: when the mobile terminal is in a first network connection state, if a target event which needs to be executed under a second network is detected, a first cell list under the first network is obtained, wherein the first cell list comprises a target first cell, when a historical target event is triggered, the target first cell is connected with the mobile terminal, and a base station does not send a connection release instruction with the target first cell to the mobile terminal; determining whether a current first cell currently connected with the mobile terminal belongs to a target first cell; if yes, disconnecting the connection with the current first cell, and acquiring a second cell reselection list of a second network, wherein the second cell reselection list comprises a target second cell, and when a historical target event is triggered, the mobile terminal reselects from the target first cell to the target second cell; and determining a target second cell corresponding to the current first cell based on the second cell reselection list, and connecting with the target second cell.
Fig. 1 is a schematic view of a network switching device according to an embodiment of the present invention, as shown in fig. 1. When the mobile terminal is in a first network connection state, if a target event needing to be executed under a second network is detected, a first cell list under the first network is obtained, wherein the first cell list comprises target first cells, when historical target events are triggered, the target first cells are connected with the mobile terminal, and the base station does not send a connection release instruction with the target first cells to the mobile terminal. The mobile terminal determines whether a current first cell currently connected belongs to a target first cell; if yes, disconnecting the connection with the current first cell, and acquiring a second cell reselection list of a second network, wherein the second cell reselection list comprises a target second cell, and when a historical target event is triggered, the mobile terminal reselects from the target first cell to the target second cell; and the mobile terminal determines a target second cell corresponding to the current first cell based on the second cell reselection list and is connected with the target second cell.
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. when the mobile terminal is in a first network connection state, if a target event which needs to be executed under a second network is detected, a first cell list under the first network is obtained, wherein the first cell list comprises a target first cell, when a historical target event is triggered, the target first cell is connected with the mobile terminal, and a base station does not send a connection release instruction with the target first cell to the mobile terminal.
In the embodiment of the invention, the first network is a 5G network, the second network is a 4G network, the target event is a session event, that is, when the mobile terminal is connected with the 5G network, if the session event which needs to be executed under the 4G network is detected, an NR cell list under the 5G network is obtained. For example, the mobile terminal starts a VoNR call and needs to reselect to LTE for VoLTE.
The first cell list comprises a target first cell, when a historical target event is triggered, the target first cell is connected with the mobile terminal, and the base station does not send a connection release instruction with the target first cell to the mobile terminal. For example, after a mobile terminal connects to a NR cell and issues a session progress for the first time, if the network does not issue a Release (Release) instruction for an infinite resource control (RRC) of the NR cell at this time, the mobile terminal records information of the NR cell as a target first cell. The RRC Release is the connection Release instruction described above.
202. It is determined whether the current first cell of the current connection belongs to the target first cell.
In the embodiment of the invention, the mobile terminal determines whether the currently connected cell belongs to the target first cell, and the currently connected cell is set as the current first cell. For example, according to the identification information and the frequency point information of the current first cell and the identification information and the frequency point information recorded in the first cell list, whether the target first cell belongs to is judged.
If the current first cell currently connected does not belong to the target first cell, the connection with the current first cell is disconnected, the current first cell is reselected to a third cell under the second network, and the target event is executed through the third cell. Before disconnecting from the current first cell, a Radio Link Failure (RLF) of the first network needs to be reported to the network side after a preset waiting time. For example, when the NR cell in which the mobile terminal currently resides is not a cell recorded in the first cell list, after a preset waiting time T, the 5G RLF needs to be reported, and then LTE is reselected, and a call is performed through VoLTE.
203. If yes, disconnecting the connection with the current first cell, and acquiring a second cell reselection list of the second network, wherein the second cell reselection list comprises a target second cell, and when a historical target event is triggered, the mobile terminal reselects from the target first cell to the target second cell.
In the embodiment of the invention, if the current first cell currently connected with the mobile terminal belongs to the target first cell, the connection with the current first cell is disconnected, and a second cell reselection list of the second network is directly obtained, wherein the second cell reselection list comprises the target second cell, and when a historical target event is triggered, the mobile terminal reselects from the target first cell to the target second cell.
When the mobile terminal is connected with an NR cell, if a target event which needs to be executed under a 4G network is triggered, and a base station does not send a connection release instruction with the NR cell to the mobile terminal, the mobile terminal reselects to a certain LTE cell after a preset waiting time, at this time, information of the reselected LTE cell is recorded, and a corresponding mapping relation is established with the information of the NR cell.
The mapping relation between the NR cell and the LTE cell specifically comprises the following steps: acquiring identification information and frequency point information of a target first cell, and generating mark information of the target first cell based on the identification information and the frequency point information of the target first cell; acquiring identification information and frequency point information of a target second cell, and generating mark information of the target second cell based on the identification information and the frequency point information of the target second cell; and establishing a mapping relation between the target first cell and the second cell based on the marking information of the target first cell and the marking information of the corresponding target second cell.
The step of establishing a mapping relationship between the target first cell and the target second cell based on the mark information of the target first cell and the mark information of the corresponding target second cell includes: acquiring the occurrence times of a target event within a preset time, wherein the target event is that when the mobile terminal is connected with a target first cell, if the target event which needs to be executed under a second network is detected, the base station does not send a connection release instruction with the target first cell to the mobile terminal; if the occurrence times are greater than the preset times, establishing a mapping relation between the target first cell and the target second cell based on the mark information of the target first cell and the mark information of the corresponding target second cell. That is, in the preset time T, the number of times of occurrence of the above situation is N times, and is greater than the preset number of times, the mapping relationship between the target first cell and the target second cell is established. For example, when there is VoNR call in NR Cell 1 and freq 1, the base station does not issue RRC Release, and at this time, the corresponding mobile terminal disconnects itself from the NR Cell, and reselects to LTE Cell 2 and freq 2; and establishing a corresponding mapping relation between NR cells Cell 1 and freq 1 and LTE cells Cell 2 and freq 2.
204. And determining a target second cell corresponding to the current first cell based on the second cell reselection list, and connecting with the target second cell.
In the embodiment of the invention, the mobile terminal determines the target second cell corresponding to the current first cell based on the second cell reselection list and connects with the target second cell. The mobile terminal can determine the target first cell based on the marking information of the current first cell; and determining a target second cell corresponding to the current first cell from the second cell reselection list based on the mapping relation between the target first cell and the target second cell.
When the target event is triggered, if a first cell in the first cell list receives a connection release instruction sent by the base station, the first cell receiving the connection release instruction is deleted from the first cell list. For example, the mobile terminal may perform a VoNR call at intervals, and if the currently connected cell is a cell in the first cell list, but a connection release instruction issued by the base station may be received at this time, the first cell is deleted from the first cell list, that is, the first cell list is updated in real time.
Referring to fig. 3, fig. 3 is a flow chart of another network switching method according to an embodiment of the invention. After the mobile terminal sends a Session Progress for the first time, the network does not issue an NR cell and a frequency point of RRC Release, and backups and marks the NR cell and the frequency point to form an NR mark list. After waiting for T (> =8s), the corresponding UE reports the 5G RLF, then reselects to LTE, registers IMS through EPS Fallback, and guarantees the call with VoLTE. The LTE cells and the frequency points reselected at the moment are backed up and marked to form a specific LTE preferred cell list. If the situation is continuously met for N times in the same place within the time T, the backed-up NR and LTE cells and frequency points are used as the corresponding mapping relation.
As shown in fig. 3, when the mobile terminal performs the VoNR call again, if it is predicted that the currently resident NR cell is the above marked cell and frequency point, the mobile terminal directly does not need to wait for the time T, and automatically adopts RLF to disconnect NR, and simultaneously matches the corresponding marked LTE cell and frequency point, so that the UE can quickly select the marked LTE cell and frequency point, skip operations such as LTE searching again, measuring, and the like, and execute the VoLTE call after time consumption is reduced and attachment is performed. The scheme enables the UE to quickly make a decision under the same condition through the previous backup and mark list, and reduces the overall switching time.
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.

For example, the first network is a 5G network, the second network is a 4G network, the target event is a session event, that is, when the mobile terminal is connected to the 5G network, if a session event that needs to be executed under the 4G network is detected, an NR cell list under the 5G network is obtained. For example, the mobile terminal starts a VoNR call and needs to reselect to LTE for VoLTE.
