[0156] Embodiment 1:

[0157] Please refer to Figure 4 The network selection method of the embodiment of the present application includes the following steps:

[0158] Step 101: The terminal executes non-computing services on network 1;

[0159] Step 102: The terminal determines to select a network for computing power services after judgment;

[0160] In an embodiment of the present application, if the network selection mode of the terminal is the first network selection mode, it is decided to execute the network selection for the computing power service; the computing power service is considered when selecting the network in the first network selection mode.

[0161] The first network selection mode may be an automatic network selection mode that takes computing power business into consideration, or may be a new network selection mode that is different from the existing automatic network selection mode and manual network selection mode;

[0162] Step 103: The terminal saves the current network selection mode (i.e., the second network selection mode) and the currently registered network (i.e., network 1); computing power services are not considered when selecting a network in the second network selection mode;

[0163] Step 104: The terminal determines whether the first network that supports the computing power service and has been successfully registered is saved; if so, proceed to step 105; otherwise, proceed to step 106;

[0164] Step 105: If the terminal has saved network 2, and network 2 is the first network that supports computing power services and has been successfully registered, then select network 2, or an equivalent network of network 2, or a network with a higher priority and supporting computing power services (such as a home network);

[0165] Step 106: If the terminal does not save the first network, select a network with the highest priority that supports the computing power service;

[0166] Step 107: When the terminal needs to perform computing services, it attempts to access the selected network;

[0167] Step 108: The terminal saves the current network selection mode (i.e., the first network selection mode) and the currently registered network (i.e., network 2); computing power services are considered when selecting a network in the first network selection mode;

[0168] Step 109: The terminal determines that it needs to reselect a network, for example, when the terminal is turned on, the network coverage is restored after the network coverage is lost, or a background search is performed, the terminal will reselect a network;

[0169] Step 110: The terminal determines whether the current network selection mode is the first network selection mode, if yes, proceeds to step 104, otherwise proceeds to step 111;

[0170] Step 111: The terminal selects a network according to the second network mode.

[0171] Embodiment 2:

[0172] Please refer to Figure 5 The network selection method of the embodiment of the present application includes the following steps:

[0173] Step 201: The terminal sends an access request to the network 1 supporting the computing service;

[0174] Step 202: Network 1 determines to approve the access request of the terminal and allocates dedicated network resources, such as wireless resources, to the terminal.

[0175] Since computing services may involve a large amount of data transmission and reception, in order to avoid affecting the current cell and other users, dedicated network resources, such as wireless resources, can be allocated to the computing services.

[0176] Step 202: Network 1 sends a notification to the terminal to notify the terminal of approving the terminal's access request and notifying the terminal of the dedicated network resources allocated to the terminal;

[0177] Step 203: The terminal executes computing services on the dedicated network resources allocated by network 1.

[0178] Embodiment 3:

[0179] Please refer to Figure 6 The network selection method of the embodiment of the present application includes the following steps:

[0180] Step 301: The terminal attempts to access network 1 that supports computing services;

[0181] Step 302: The terminal determines whether the access is successful. If the access fails, the process proceeds to step 303. If the access is successful, but the network coverage area is lost during the execution of the computing service, after re-entering the network coverage area, the terminal cannot search for the previously registered network 1 supporting the computing service, and the process proceeds to step 303.

[0182] Step 303: The terminal determines whether there are other networks that support the computing power service; if yes, proceed to step 304; otherwise, proceed to step 306;

[0183] Step 304: The terminal selects and attempts to access the other network, such as network 2;

[0184] Step 305: The terminal determines whether the access to network 2 is successful. If the access fails, the process goes to step 303.

[0185] Step 306: The terminal selects a network according to the second network selection mode, and the computing power service is not considered when selecting a network in the second network selection mode.

[0192] Step 402: When the terminal needs to perform a computing service, the terminal sorts the multiple networks according to the stored computing service information of the multiple networks;

[0193] For example, the multiple networks may be sorted according to the computing speed supported by the networks and / or according to the order in which the networks are signed.

[0194] Step 403: The terminal selects a network according to the sorting result.

[0195] Embodiment 5:

[0196] Please refer to Figure 8 The network selection method of the embodiment of the present application includes the following steps:

[0197] Step 501: The terminal executes a computing service in the network 1 supporting the computing service;

[0198] Step 502: The user selects a second network selection mode, in which computing power services are not considered when selecting a network;

[0199] In the embodiment of the present application, the terminal UE believes that the user wants to leave the first network selection mode and no longer needs to perform the computing power service, so the first network selection mode and the network registered in the first network selection mode can be deleted, and the computing power service is considered when selecting the network in the first network selection mode;

[0200] Step 503: The terminal selects network 2, which does not support computing services, and attempts to access network 2 when necessary.

[0201] In the embodiment of the present application, the user or the upper layer of the terminal can change the network selection mode from the first network selection mode to the second network selection mode.

[0205] Step 602: The terminal obtains the computing power service information of the network from the air interface and sends it to the upper layer or user of the terminal, for example, together with the network ID, to assist the upper layer or user in subsequent actions, such as network selection.

[0206] Step 603: The user performs manual network selection based on the computing power service information of the network and selects network 2 that supports the computing power service;

[0207] Step 604: The terminal selects network 2 and attempts to access it when necessary.

[0208] Embodiment 7:

[0209] Please refer to Fig.10 The network selection method of the embodiment of the present application includes the following steps:

[0210] Step 701: The terminal executes a computing service in a network 1 that supports the computing service;

[0211] Step 702: During the execution of the computing service, the terminal may select a network with a higher priority. For example, in the idle state, the terminal searches for a network 2 with a higher priority that supports the computing service.

[0212] The priority here can be a priority sorted according to computing power capability, that is, computing power priority; the terminal can obtain the computing power priority of the network from the air interface, for example, from a broadcast message, or from a NAS message, such as a registration message.

[0213] Step 703: The terminal selects the network 2 with a higher priority and attempts to access it when necessary.

[0214] Embodiment 8:

[0215] Please refer to Fig.11 The network selection method of the embodiment of the present application includes the following steps:

[0216] Step 801: The terminal executes a computing service in a network 1 that supports the computing service;

[0217] Step 802: The terminal remains in the current network and does not perform periodic high-priority network searches.

[0218] During the execution of computing services, a large amount of data transmission and calculation may be involved, and the terminal may not perform periodic high-priority network searches.
