Background Art

[0003] In order to support the needs of vertical industries, the concept of a non-public network (NPN) has currently been introduced. For example, it provides users with a "private" network independent of the public network, such as a stand-alone non-public network (SNPN) or a non-stand-alone non-public network (public network integrated non-public network, PNI-NPN).

[0004] In the same location, multiple types of networks are simultaneously available. For example, an SNPN available at a specific time and location (abbreviated as a hosting SNPN), an SNPN without specific time and location restrictions (abbreviated as a normal SNPN), or a public land mobile network (PLMN). Therefore, for those skilled in the art, when multiple types of networks are available, how to select a network has become an urgent technical problem to be solved.

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

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

[0022] Specifically, at the same location, one or more types of networks may be available simultaneously, and a hosting network may be set at a specific time and location. In this case, the terminal can access the hosting network at that time and location to obtain local services. Here, the hosting type NPN can be a hosting type SNPN or a hosting type PNI-NPN, that is, an NPN available at a specific time and location.

[0023] The terminal can select a target network to be accessed including, for example, any one of a hosting type NPN, a normal NPN, or a PLMN based on the network selection mode. Among them, the normal NPN is a non-public network that does not specify time and / or location.

[0024] The network selection mode can be, for example, set by network-side devices, predefined by protocols, or determined by the terminal.

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

[0026] In the method of this embodiment, when there are multiple types of networks, the terminal can select a target network including any one of a hosting type NPN, a normal NPN, or a public land mobile network (PLMN) as the network to be accessed based on the network selection mode. Thereby, network selection can be performed efficiently, the network selection efficiency is improved, and the complexity is low.

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

[0028] Optionally, when the hosting type NPN includes a hosting type SNPN and the normal NPN includes a normal SNPN, step 101 can be implemented in the following manner.

[0029] Method 1: When the network selection mode is the non-SNPN access mode, the terminal uses the PLMN as the network to be accessed. When the network selection mode is the SNPN access mode, the terminal uses the hosting type SNPN or the normal SNPN as the network to be accessed.

[0030] Specifically, when the terminal is in the non-SNPN access mode, the terminal selects the PLMN as the network to be accessed. Optionally, in this mode, only the PLMN is selected regardless of whether there is an available PLMN. When the terminal is in the SNPN access mode, the terminal can select the hosting type SNPN or the normal SNPN as the network to be accessed. Optionally, in this mode, only the hosting type SNPN or the normal SNPN is selected regardless of whether there is an available hosting type SNPN or normal SNPN.

[0031] Optionally, when the network availability conditions of the hosted SNPN are met, the terminal prioritizes the hosted SNPN as the network to be accessed, When the network availability conditions of the hosted SNPN are not met, the terminal either prioritizes the regular SNPN as the network to be accessed or uses only the regular SNPN as the network to be accessed.

[0032] Optionally, the fact that the network availability conditions of the hosted SNPN are met includes that the current time is within the time range when the hosted SNPN can be used and / or the current position of the terminal is within the position range where the hosted SNPN can be used.

[0033] Specifically, when the network availability conditions of the hosted SNPN are met, for example, the current time of the terminal's network selection is within the time range when the hosted SNPN can be used and / or the current position of the terminal is within the position range where the hosted SNPN can be used. In this case, the terminal can prioritize the hosted SNPN as the network to be accessed.

[0034] When the network availability conditions of the hosted SNPN are not met, the terminal either prioritizes the regular SNPN as the network to be accessed or uses only the regular SNPN as the network to be accessed, that is, regardless of whether there is an available regular SNPN, only the SNPN is selected.

[0035] Optionally, the network availability conditions are set for the terminal based on the terminal's contract information or are sent from the network-side device to the terminal.

[0036] In the above embodiment, when the hosted SNPN or the regular SNPN can be selected, the hosted SNPN with lower implementation complexity can be preferentially selected.

[0037] Method 2: When the network selection mode is the arbitrary mode and the hosting type SNPN is available, if the hosting type SNPN is available, the terminal uses the hosting type SNPN as the network to be accessed.

[0038] Specifically, based on the feature that the hosting type SNPN has time and location restrictions, for the hosting type SNPN, there is no need to consider the network selection mode. That is, in either the SNPN access mode or the non-SNPN access mode, if the hosting type SNPN is available, the terminal accesses the hosting type 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 of the terminal is high.

[0040] Optionally, when the network selection mode is the SNPN access mode and the network availability condition of the hosting type SNPN is satisfied, the terminal gives priority to the hosting type SNPN as the network to be accessed. When the network selection mode is the non-SNPN access mode and the network availability condition of the hosting type SNPN is satisfied, the terminal gives priority to the hosting type SNPN as the network to be accessed.

[0041] Specifically, in either the SNPN access mode or the non-SNPN access mode, when the network availability condition of the hosting type SNPN is satisfied, the hosting type SNPN is preferentially selected.

[0042] Optionally, the method is When the network selection mode is the SNPN access mode and the network availability condition of the hosting-type SNPN is not satisfied, the terminal gives priority to the normal SNPN as the network to wait for access or uses only the normal SNPN as the network to wait for access. When the network selection mode is the non-SNPN access mode and the network availability condition of the hosting-type SNPN is not satisfied, the terminal further includes giving priority to the normal SNPN as the network to wait for access or using only the normal SNPN as the network to wait for access.

[0043] Specifically, in either the SNPN access mode or the non-SNPN access mode, when the network availability condition of the hosting-type SNPN is not satisfied, the normal SNPN is preferentially selected or only the normal SNPN is selected (for example, regardless of whether the normal SNPN is available, only the normal SNPN is selected).

[0044] Furthermore, when the network availability condition of the hosting-type SNPN is satisfied, the terminal gives priority to enabling the SNPN access mode. That is, the hosting-type SNPN or the normal SNPN can be preferentially selected.

[0045] Method 3: When the network availability condition of the hosting-type SNPN is satisfied, the terminal enables the target network selection mode. The terminal uses the hosting-type SNPN as the network to wait for access, or The terminal uses the hosting-type SNPN or the normal SNPN as the network to wait for access, or The terminal uses any one of the hosting-type SNPN, the normal SNPN, or the PLMN as the network to wait for access.

[0046] Optionally, the terminal using the hosting type SNPN or the normal SNPN as the access waiting network includes the terminal preferring the hosting type SNPN as the access waiting network, and the above-mentioned use of the hosting type SNPN, the normal SNPN or any one of the PLMNs by the terminal as the access waiting network includes the terminal preferring the hosting type SNPN as the access waiting network.

[0047] Specifically, when the network availability condition of the hosting type SNPN is satisfied, a new target network selection mode can be enabled to allow access only to the hosting type SNPN, or to allow access only to the hosting type SNPN or the normal SNPN (for example, the hosting type SNPN may be preferentially selected), or to allow access to the hosting type SNPN, the normal SNPN or the PLMN (for example, the selected hosting type SNPN may be preferentially selected).

[0048] In the above embodiment, when the network availability condition of the hosting type SNPN is satisfied, the terminal enables the target network selection mode, and in this target network selection mode, the hosting type SNPN can be preferentially selected, thereby assisting the terminal to effectively perform network selection, improving the network selection efficiency, and reducing complexity.
