[0101] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0102] like Figure 1 As shown, an embodiment of the present invention provides a method for selecting an independent non-public network SNPN, which is applied to a terminal, including:

[0103] Step 101, obtaining the service support capability information of the SNPN currently accessible to the terminal;

[0104] Step 102: Select an SNPN based on the current service demand of the terminal and the service support capability information of the SNPN that the terminal can currently access.

[0105] In this step, the service demand includes "voice centric" centered on voice service and / or "data centric" centered on data service.

[0106] It should be noted that the service support capability information of the SNPN mentioned in step 101 of the embodiment of the present invention includes at least two acquisition methods as follows:

[0107] Method 1: Step 101 includes:

[0108] Obtain a broadcast message sent by a network-side device; the broadcast message carries the service support capability information of the SNPN; the broadcast message also carries a list of available SNPN identifiers. For example, the SNPN identifier is: PLMN ID+NID (network identification code). For another example, the broadcast message carries a list of SNPN identifiers and the service support capability information corresponding to each SNPN identifier;

[0109] Method 2: Step 101 includes:

[0110] Obtain the service support capability information of the pre-configured SNPN; similarly, the identifier list of the SNPN supported by the terminal needs to be pre-configured. For example, the identifier of the SNPN is: PLMN ID+NID (network identification code). For another example, the identifier list of the SNPN supported by the terminal and the service support capability information corresponding to each SNPN identifier are pre-configured.

[0111] Following the above example, step 102 in the embodiment of the present invention includes:

[0112] If the broadcast message carries the service support capability information of the SNPN, the SNPN selection is performed according to the current service needs of the terminal and the service support capability information of the SNPN carried in the broadcast message; that is, the terminal obtains the list of available SNPN network numbers (PLMN ID+NID) and the service support capability information of its network through the wireless side broadcast message, and the terminal selects the network based on its own service needs and the service support capability information of the SNPN network obtained from the broadcast message.

[0113] Alternatively, step 102 includes:

[0114] If the broadcast message does not carry the service support capability information of the SNPN, the SNPN selection is performed according to the current service requirements of the terminal and the service support capability information of the pre-configured SNPN. That is, the terminal pre-configures the SNPN list supported by itself and the service support capability information of each SNPN network. When the terminal does not receive the service support capability information of the SNPN carried in the broadcast message, the terminal selects the network based on its own service requirements and the service support capability information of the pre-configured SNPN network.

[0115] As an optional embodiment, the service support capability information of the SNPN includes at least one of the following:

[0116] Voice service support capability information of the SNPN;

[0117] The mutual access capability information between the SNPN and the public land mobile communication network PLMN.

[0118] For example, Service Capability Indicator (SCI) is used to represent the service support capability information of the SNPN, and an example of a network side device carrying the service support capability information of the SNPN through a broadcast message is as follows:

[0119] SNPN Information

[0120] PLMN1

[0121] NID1, SCI

[0122] NID2, SCI

[0123] …

[0124] PLMN2

[0125] NID3, SCI

[0126] NID4, SCI

[0127] …

[0128] The voice service support capability information of the SNPN includes:

[0129] The first identification information identifies whether the SNPN supports the IMS voice service.

[0130] For example, the first identification information is indicated by a bit field, and the bit field is "1" to indicate that the SNPN supports the IMS voice service; the bit field is "0" to indicate that the SNPN does not support the IMS voice service. Alternatively, the bit field is "0" to indicate that the SNPN supports the IMS voice service; the bit field is "1" to indicate that the SNPN does not support the IMS voice service.

[0131] The voice service support capability information of the SNPN includes at least one of the following:

[0132] Second identification information indicating whether the SNPN network supports voice fallback services and 5G voice services; wherein the voice fallback service is a voice service that falls back from 5G to 4G (i.e., EPS fallback service);

[0133] Third identification information indicating whether the SNPN network supports only 5G voice services;

[0134] Fourth identification information indicating whether the SNPN network supports only the voice fallback service.

[0135] For example, the third identification information is indicated by the first bit field, the fourth identification information is indicated by the second bit field, and the second identification information is indicated jointly by the first bit field and the second bit field. For example, "the first bit field is 1 and the second bit field is 0" indicates that the SNPN network only supports 5G voice services; "the first bit field is 0 and the second bit field is 1" indicates that the SNPN network only supports voice fallback services; "the first bit field is 1 and the second bit field is 1" indicates that the SNPN network supports both voice fallback services and 5G voice services; "the first bit field is 0 and the second bit field is 0" indicates that the SNPN network supports neither voice fallback services nor 5G voice services.

[0136] As an optional embodiment, the mutual access capability information between the SNPN and the public land mobile communication network PLMN includes at least one of the following:

[0137] Access PLMN via SNPN;

[0138] Access SNPN via PLMN.

[0139] As an optional embodiment, before step 101, the method further includes:

[0140] The SNPN currently accessible to the terminal is determined according to the SNPN identification list supported by the terminal and the available SNPN identification list in the network broadcast message.

[0141] For example, the terminal preconfigures the SNPN identification list supported by itself (which may be referred to as SNPN List 1) and the available SNPN identification list in the broadcast message (which may be referred to as SNPN List 2) to determine the currently accessible SNPN identification list. Optionally, the intersection of SNPN List 1 and SNPN List 2 may be taken to obtain the currently accessible SNPN identification list.

[0142] In summary, in the embodiment of the present invention, the terminal selects the SNPN based on its own service requirements and the service support capability information of the currently accessible SNPN, thereby improving the network selection efficiency.

[0143] like Figure 2 As shown, an embodiment of the present invention also provides a configuration method of an independent non-public network SNPN, which is applied to a network side device, including:

[0144] Step 201: Send a broadcast message, which carries a list of available SNPN identifiers and service support capability information of each SNPN.

[0145] As an optional embodiment, the service support capability information of the SNPN includes at least one of the following:

[0146] Voice service support capability information of the SNPN;

[0147] The mutual access capability information between the SNPN and the public land mobile communication network PLMN.

[0148] The voice service support capability information of the SNPN includes:

[0149] The first identification information identifies whether the SNPN supports the IMS voice service.

[0150] For example, the first identification information is indicated by a bit field, and the bit field is "1" to indicate that the SNPN supports the IMS voice service; the bit field is "0" to indicate that the SNPN does not support the IMS voice service. Alternatively, the bit field is "0" to indicate that the SNPN supports the IMS voice service; the bit field is "1" to indicate that the SNPN does not support the IMS voice service.

[0151] The voice service support capability information of the SNPN includes at least one of the following:

[0152] Second identification information indicating whether the SNPN network supports voice fallback services and 5G voice services; wherein the voice fallback service is a voice service that falls back from 5G to 4G (i.e., EPS fallback service);

[0153] Third identification information indicating whether the SNPN network supports only 5G voice services;

[0154] Fourth identification information indicating whether the SNPN network supports only the voice fallback service.

[0155] For example, the third identification information is indicated by the first bit field, the fourth identification information is indicated by the second bit field, and the second identification information is indicated jointly by the first bit field and the second bit field. For example, "the first bit field is 1 and the second bit field is 0" indicates that the SNPN network only supports 5G voice services; "the first bit field is 0 and the second bit field is 1" indicates that the SNPN network only supports voice fallback services; "the first bit field is 1 and the second bit field is 1" indicates that the SNPN network supports both voice fallback services and 5G voice services; "the first bit field is 0 and the second bit field is 0" indicates that the SNPN network supports neither voice fallback services nor 5G voice services.

[0156] For another example, Service Capability Indicator (SCI) is used to represent the service support capability information of the SNPN, and an example in which the network side device carries the service support capability information of the SNPN through a broadcast message is as follows:

[0157] SNPN Information

[0158] PLMN1

[0159] NID1, SCI

[0160] NID2, SCI

[0161] …

[0162] PLMN2

[0167] Access PLMN via SNPN;

[0168] Access SNPN via PLMN.

[0169] In summary, in the embodiment of the present invention, the terminal selects the SNPN based on its own service requirements and the service support capability information of the currently accessible SNPN, thereby improving the network selection efficiency.

[0170] It should be noted that the "service support capability information" of the SNPN mentioned in the embodiment of the present invention may also be referred to as: service capability, service capability indicator, service support capability, and service support identification.

[0171] The “voice service support capability information” of the SNPN mentioned in the embodiment of the present invention may also be referred to as: IMS voice service capability (IMS voice service capability) or voice service capability (voice service capability).

[0172] The “interaccess capability information between SNPN and PLMN” mentioned in the embodiment of the present invention may also be referred to as: interworking capability for SNPN and PLMN, or interaction capabilityfor SNPN and PLMN, or inter-access capability for SNPN and PLMN, or Access toPLMN via SNPN, or Access to SNPN via PLMN.

[0173] In order to more clearly describe the SNPN selection method provided in the embodiment of the present invention, the following is a description of the processing logic of the terminal and the network side device. Figure 3 As shown:

[0178] Step 4a: If yes, the terminal selects to access a certain SNPN from the SNPN list 3 according to the terminal policy.

[0179] Step 4b, if not, determine whether the network broadcast message carries service support capability information of the accessible SNPN network;
