To enable communication of a first communication network (e.g., 5G), the electronic device needs to support a protocol version above the specification Release a (e.g., Release 15). At present, although the network construction speed is accelerated, most areas are still covered by a second communication network (for example: 4G); when the electronic device is under the coverage of the second communication network, the situation of incompatible parameters may occur when some Release parameters are reported because the electronic device is not in the coverage area of the first communication network, which affects the normal second communication network service performed by the electronic device, and causes abnormal communication of the electronic device.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.

The embodiment of the invention provides a network switching method, which is applied to electronic equipment.

Referring to fig. 1, fig. 1 is a flowchart of a network handover method according to an embodiment of the present invention, and as shown in fig. 1, the network handover method includes the following steps:

step 101, acquiring Release version information matched with a target communication network under the condition that the electronic equipment is switched to the target communication network.

In the embodiment of the present invention, the target communication network may refer to a 3G communication network, a 4G communication network, a 5G communication network, and the like. The electronic device switching to the target communication network may refer to switching from one communication network to another, for example may refer to switching from a 4G communication network to a 5G communication network.

Optionally, in a case that the electronic device is handed over to a target communication network, the method includes:

under the condition that the electronic equipment is detected to start a target communication network function, determining that the electronic equipment is switched to a first communication network; alternatively, the first and second electrodes may be,

and under the condition that the electronic equipment is detected to close the target communication network function, determining that the electronic equipment is switched to a second communication network.

In this embodiment, the first communication network is a 5G communication network, and the second communication network may refer to a non-5G communication network, such as a 4G communication network or a 3G communication network. Alternatively, the electronic device may be a 5G switch provided with a virtual; when the electronic equipment is in a non-5G communication network, for example, a 4G communication network, if it is detected that the 5G switch is turned on by a user, that is, it is detected that the electronic equipment turns on a target communication network function, it is determined that the electronic equipment is switched from the 4G communication network to the 5G communication network; when the electronic equipment is in the 5G communication network, if the 5G switch is detected to be closed by a user, the electronic equipment is determined to be switched from the 5G communication network to the 4G communication network.

Of course, the electronic device may also implement the switching of the communication network by other means, for example, by identifying a SIM (Subscriber Identity Module) card of the electronic device to determine whether the electronic device is switched to the target communication network.

In the embodiment of the invention, when the electronic equipment is detected to be switched to the target communication network, the Release version information corresponding to the target communication network is acquired. Wherein the Release version information at least comprises a level of a Release version. Release may refer to a communication specification, or communication protocol; the level of the Release version may be determined by a value corresponding to the Release version, for example, the value corresponding to the Release15 version is 0xC0, the value corresponding to the Release 11 version is 0x80, and the Release version information may also refer to the value corresponding to the Release version.

In this step, the level of the Release version can be determined by the Release version information, and thus the target communication network is determined. For example, when the obtained Release version information is 0xC0, it is known that the level of the Release version is Release15 version, and it can be determined that the target communication network is the 5G communication network.

And 102, when detecting that the electronic equipment initiates network registration or position updating, performing network registration according to the Release version information.

It should be noted that the initiation of network registration by the electronic device may refer to establishment of connection between the electronic device and the communication base station to implement data transmission; the location update of the electronic device may refer to a change in location of the electronic device between different base station coverage cells, e.g., from an a-cell to a B-cell.

In the embodiment of the invention, when the electronic equipment is detected to initiate network registration or position updating, the electronic equipment performs network registration according to the determined target communication network and the Release version information.

Specifically, when a modem DS (Data Services, Data service) module in the electronic device notifies a modem NAS (Non Access Stratum) module to initiate network registration or TAU (Tracking area update), the modem NAS module reads Release version information when assembling a capability IE (electronic device capability related parameter set) carried by the network registration or location update, and then performs network registration according to the Release version information.

Optionally, the performing network registration according to the Release version information includes:

adding a Release parameter corresponding to the target Release version in the electronic equipment capability related parameter set under the condition that the level of the Release version is greater than or equal to that of the target Release version, and performing network registration; alternatively, the first and second electrodes may be,

and under the condition that the level of the Release version is smaller than the target Release version, not adding a Release parameter corresponding to the target Release version in the electronic equipment capability related parameter set, and performing network registration.

Alternatively, the target Release version may refer to Release15 version.

In the embodiment of the invention, after acquiring the Release version information matched with the target communication network, the electronic equipment can determine the level of the corresponding Release version according to the Release version information, and further judge whether the level of the Release version is greater than or equal to the target Release version.

For example, the target Release version refers to a Release15 version, and if the level of the Release version is a Release15 version, adding a Release parameter corresponding to the Release15 version in an electronic device capability related parameter set (capability IE) carried by the modem NAS module assembly network registration or location update, and performing network registration, for example, initiating network registration through the modem NAS module.

If the level of the Release version is less than the Release15 version, for example, the level of the Release version is the Release 11 version, then no Release parameter corresponding to the Release15 version is added to an electronic device capability related parameter set (capability IE) carried by the modem NAS module assembly network registration or location update, and the electronic device may not carry related parameters of the Release15 version, but may carry related parameters corresponding to the Release 11 version, and then network registration is performed.

According to the technical scheme provided by the embodiment of the invention, when the electronic equipment is switched to the target communication network, the Release version information matched with the target communication network is obtained, namely the level of the Release version can be obtained, and further, when the electronic equipment is detected to initiate network registration or position updating, the network registration can be carried out according to the Release version information. Therefore, when the electronic equipment is switched among different communication networks, the matched Release version information can be adjusted, the situation that Release parameters of the electronic equipment are incompatible is avoided, and the communication of the electronic equipment is smooth.

For example, the electronic device is a 5G mobile phone, and in the prior art, when the 5G mobile phone is in a base station of only a 4G communication network, SRVCC (single radio Voice Call Continuity) function of a Voice over Long-Term Evolution Voice bearer (lte) service is abnormal, because the 5G mobile phone supports Release15 version, when requesting for 4G network registration in the base station of the 4G communication network, related parameters of Release15 version may be carried, and the network is incompatible, which may cause the 5G mobile phone to be abnormal in function. In the scheme provided by the embodiment of the invention, because the electronic equipment can acquire the Release version information matched with the target communication network when being switched to the target communication network, namely, the 5G mobile phone can acquire the Release version information matched with the 4G communication network when being switched to the 4G communication network, and then the 5G mobile phone performs 4G communication network registration according to the Release version information matched with the 4G communication network, because the 5G mobile phone does not carry related parameters of the Release15 version, the situation of network incompatibility can not occur, and the normal communication of the 5G mobile phone under the 4G communication network is ensured.

Optionally, the obtaining Release version information corresponding to the target communication network in step 101 may include:

acquiring an EFS file parameter set of the embedded file system matched with the target communication network; the EFS file parameter set includes: the path of the EFS file, the EFS file name and the Release version information.

In this case, the step 102 may further include:

generating a target EFS file according to the EFS file parameter set;

and replacing the EFS file of the electronic equipment with the target EFS file based on the path of the EFS file.

That is to say, when the electronic device is switched to the target communication network, the path of an EFS (Embedded File System) File, the EFS File name, and the Release version information that match the target communication network are obtained, the target EFS File is generated, and the EFS File of the electronic device is replaced with the target EFS File based on the path of the EFS File.

For example, when it is detected that the electronic device is switched from the 4G communication network to the 5G communication network, the electronic device obtains three parameters of a path of the EFS file corresponding to the Release version file, an EFS file name (lte _3gpp _ Release _ ver), and a value corresponding to the Release version (for example, the Release15 value is 0xC0), generates the EFS file, and places the EFS file into the corresponding EFS file system directory to replace the original EFS file according to the path of the EFS file therein. Therefore, after the electronic equipment is switched to the 5G communication network, the EFS file is correspondingly adjusted to the Release15 version matched with the 5G communication network, so that normal communication of the electronic equipment under the 5G communication network is ensured.

Or, if it is detected that the electronic device is switched from the 5G communication network to the 4G communication network, the electronic device obtains three parameters of a path of the matched EFS file, an EFS file name (lte _3gpp _ Release _ ver), and a value corresponding to a Release version (for example, a Release 11 value is 0x80), generates an EFS file, and places the EFS file into a corresponding EFS file system directory to replace the original EFS file according to the EFS file path therein. Thus, even the electronic equipment with the 5G communication function can be adjusted to the Release version corresponding to the 4G communication network after being switched to the 4G communication network, so that the situation that Release parameters are incompatible is avoided, and normal communication of the electronic equipment under the 4G communication network is ensured.

Further, after replacing the EFS file of the electronic device with the target EFS file based on the EFS file path, the method may further include:

and updating the RRC parameter according to the target EFS file.

Optionally, after the electronic device is replaced with the target EFS file, the modem EFS file system module may notify a modem RRC (Radio Resource Control) module to update parameters, and the modem RRC module reads the Release version EFS file corresponding to the target communication network again to update RRC parameters. Therefore, the target communication network is switched by the electronic equipment, and after the Release version information matched with the target communication network is adjusted, other parameters related to Release in the electronic equipment can be correspondingly adjusted to ensure normal communication of the electronic equipment.
