[0020] Hereinafter, with reference to the drawings, the network selection method provided by the embodiments of the present application will be described in detail through several embodiments and their application scenarios.

[0021] 2 is a flowchart of a network selection method provided by an embodiment of the present application. As shown in FIG. 2, the method provided by this embodiment includes: The method includes step 101 in which the terminal selects, based on a network selection mode, a target network including any of a hosted non-public network NPN, a normal NPN or a public land mobile network PLMN as a network waiting to be accessed.

[0022] Specifically, more than one type of network may be available at the same time in the same location, and a hosting network may be established at a specific time and location, in which case a terminal may access the hosting network at that time and location to obtain local services. Here, the hosted NPN may be a hosted SNPN or a hosted PNI-NPN, i.e., an NPN available at a specific time and location.

[0023] The terminal may select a target network to wait for access based on the network selection mode, including, for example, a hosted NPN, a regular NPN, or a PLMN, where a regular NPN is a non-public network that does not specify time and / or location.

[0024] The network selection mode may be, for example, set by the network side device, predefined in a protocol, or determined by the terminal.

[0025] The network selection mode can specify, for example, information about which network is preferentially selected or which network only can be selected.

[0026] In the method of this embodiment, when there are multiple types of networks, the terminal can select a target network, including any of a hosted NPN, a normal NPN, or a public land mobile network (PLMN), as a network waiting to be accessed based on a network selection mode, thereby enabling efficient network selection, improving network selection efficiency, and reducing complexity.

[0027] Optionally, as shown in FIG. 3, after step 101, the terminal can initiate an access request to the network side device of the access-waiting network for network access.

[0028] Alternatively, if the hosted NPN includes a hosted SNPN and the normal NPN includes a normal SNPN, step 101 can be implemented in the following manner.

[0029] Method 1: If the network selection mode is non-SNPN access mode, the terminal uses the PLMN as the network to wait for access; If the network selection mode is the SNPN access mode, the terminal uses the hosted SNPN or the normal SNPN as the network waiting for access.

[0030] Specifically, when the terminal is in a non-SNPN access mode, the terminal selects a PLMN as a network waiting to access, and optionally, in this mode, only a PLMN is selected regardless of whether there is an available PLMN; When the terminal is in the SNPN access mode, the terminal can select a hosted SNPN or a normal SNPN as the network to access. Optionally, in this mode, only a hosted SNPN or a normal SNPN is selected, regardless of whether there is an available hosted SNPN or a normal SNPN.

[0031] optionally, if the network availability condition of the hosted SNPN is satisfied, the terminal prioritizes the hosted SNPN as a network to wait for access; If the network availability condition of the hosted SNPN is not met, the terminal will either prioritize the normal SNPN as the network waiting for access or will only use the normal SNPN as the network waiting for access.

[0032] Optionally, the network availability condition for the hosted SNPN being met includes the current time being within a time range in which the hosted SNPN is available and / or the current location of the terminal being within a location range in which the hosted SNPN is available.

[0033] Specifically, if the network availability condition of the hosted SNPN is met, e.g., the current time of the terminal's network selection is within a time range in which the hosted SNPN is available and / or the terminal's current location is within a location range in which the hosted SNPN is available, the terminal can prioritize the hosted SNPN as a network to wait for access.

[0034] If the network availability condition of the hosted SNPN is not met, the terminal will either prioritize a normal SNPN as the network waiting for access or will only use a normal SNPN as the network waiting for access, i.e., only the SNPN will be selected regardless of whether there is a normal SNPN available.

[0035] Alternatively, the network availability conditions are set in the terminal based on the terminal's subscription information or are transmitted to the terminal from the network side device.

[0036] In the above embodiment, when there is a choice between a hosted SNPN and a normal SNPN, the hosted SNPN may be preferentially selected due to its lower implementation complexity.

[0037] Method 2: When the network selection mode is the arbitrary mode, if a hosted SNPN is available, the terminal uses the hosted SNPN as the network to wait for access.

[0038] Specifically, based on the characteristics that the hosted SNPN has time and location restrictions, there is no need to consider the network selection mode for the hosted SNPN, i.e., in either the SNPN access mode or the non-SNPN access mode, if the hosted SNPN is available, the terminal will access the hosted SNPN.

[0039] In the above embodiment, network selection can be performed more quickly without frequently switching the network selection mode, and the efficiency of network selection by the terminal is high.

[0040] optionally, if the network selection mode is an SNPN access mode and the network availability condition of the hosted SNPN is satisfied, the terminal prioritizes the hosted SNPN as a network to wait for access; If the network selection mode is a non-SNPN access mode and the network availability condition of the hosted SNPN is satisfied, the terminal will prioritize the hosted SNPN as the network to wait for access.

[0041] Specifically, in either the SNPN access mode or the non-SNPN access mode, if the network availability condition of the hosted SNPN is met, the hosted SNPN is preferentially selected.

[0042] Optionally, the method further comprises: When the network selection mode is an SNPN access mode and the network availability condition of the hosted SNPN is not satisfied, the terminal prioritizes the normal SNPN as the network waiting for access, or only uses the normal SNPN as the network waiting for access; If the network selection mode is a non-SNPN access mode and the network availability condition of the hosted SNPN is not satisfied, the terminal may further prioritize a normal SNPN as the network waiting for access or may only use a normal SNPN as the network waiting for access.

[0043] Specifically, in either the SNPN access mode or the non-SNPN access mode, if the network availability condition of the hosted SNPN is not met, the normal SNPN is preferentially selected or only the normal SNPN is selected (e.g., only the normal SNPN is selected regardless of whether the normal SNPN is available).

[0044] Furthermore, if the network availability condition of the hosted SNPN is met, the terminal has a preference to enable the SNPN access mode, i.e., it can preferentially select the hosted SNPN or the normal SNPN.

[0045] Method 3: If the network availability condition of the hosted SNPN is met, the terminal enables the target network selection mode; The terminal uses the hosted SNPN as a waiting network for access, or The terminal uses a hosted SNPN or a regular SNPN as the access waiting network, or The terminal uses a hosted SNPN, typically either an SNPN or a PLMN, as the network to be accessed.

[0046] Alternatively, the terminal may use a hosted SNPN or a normal SNPN as the access waiting network. The terminal prioritizes the hosted SNPN as a network to be accessed; The terminal uses either a hosted SNPN, a normal SNPN or a PLMN as a waiting network for access, This includes the terminal prioritizing the hosted SNPN as the network to wait for access.

[0047] Specifically, if the network availability condition for the hosted SNPN is met, a new target network selection mode may be enabled to allow access to only the hosted SNPN, or to allow access to only the hosted SNPN or the normal SNPN (e.g., the hosted SNPN may be preferentially selected), or to allow access to the hosted SNPN, the normal SNPN, or the PLMN (e.g., the selected hosted SNPN may be preferentially selected).

[0048] In the above embodiment, when the network availability condition of the hosted SNPN is satisfied, the terminal enables a target network selection mode, and in the target network selection mode, the terminal can preferentially select the hosted SNPN, thereby helping the terminal to perform network selection effectively, improving network selection efficiency, and reducing complexity.

[0049] In the network selection method provided by the embodiment of the present application, the execution entity may be a network selection device. In the embodiment of the present application, the network selection device provided by the embodiment of the present application will be described by taking the execution of the network selection method by the network selection device as an example.

[0051] Alternatively, if the hosted NPN includes a hosted SNPN and the normal NPN includes a normal SNPN, the processing module 210 may specifically: If the network selection mode is a non-SNPN access mode, using a PLMN as a waiting-for-access network; When the network selection mode is an SNPN access mode, the hosting type SNPN or the normal SNPN is used as the access waiting network.
