In this example, ability open platform configurating terminal access strategy.When terminal is linked into network and to energy When power open platform is registered, ability open platform subscribes to the operating mode information of terminal, and cooperates with third party Whether service and decision-making needs to initiate network section selection and handover operation.In the example, opened by ability flat Platform or third party's service provide the selection and switching service of network section for terminal, make the net for terminal service The demand of network section more laminating business.

In above-mentioned flow, if what terminal reported is newly-increased mode of operation, and ability open platform or Third party APP judges that the service network section of terminal is mismatched with the newly-increased mode of operation, then can be by The flow of network section selection and access is initiated, is repeated no more here.

Example three

In this example, terminal access strategy is handed down to the tactical management service of network side by ability open platform Device.When terminal is linked into network side, the terminal issued by network side acquisition strategy management server connects Enter strategy.Terminal is received after terminal access strategy, and the current operation mode of terminal and service network are cut The type of piece is matched, and can not such as be matched, then selection and the handover operation of network section is initiated, to net Network section switching or inquiry request are initiated in network side, obtain the information of objective network section.Then terminal from Service network section attachment removal, is linked into objective network section again.

It is the signaling process of this example shown in Figure 16：

Step S601~S602, with step S401~402；

Step S603, ability open platform manages the strategy that the terminal access strategy of generation is handed down to network side Manage server.

Step S604, terminal is linked into service network section (by taking network section A as an example).Initially connect It is fashionable, if without the network section specified, common network section can be selected to be accessed.

Step S605, terminal is linked into after service network section, and service network section is the terminal to plan Slightly management server asks the terminal access strategy of the terminal, carried terminal id.

Terminal access strategy is sent to service network and cut by step S606, the policy management servers of network side Piece.In this example, terminal access strategy is applied to various terminals, but the present invention is not limited to this, terminal Access strategy can also terminal be specifically respectively configured for single terminal.

Terminal access strategy is sent to terminal by step S607, service network section, is carried service network and is cut The type of piece, the information such as terminal access strategy.Terminal receives and preserves terminal access strategy.

Step S608, terminal determines the current operation mode of terminal (it is assumed that more according to terminal access strategy Mode of operation after new) corresponding network slice type, current operation mode and service network are cut into slices Type is matched, and can not such as be matched, then initiates selection and the handover operation of network section.

Step S609, terminal initiates network section handover request to network side, carries the corresponding network The information of slice type and the information of terminal, such as terminal i d, can be with the information of carried terminal position Deng the information useful to network orientation.

Step S610, the lateral network section management function of network sends inquiry request, and inquiry terminal needs switching The information for the objective network section arrived, is not limited to the information such as id, the IP address of network section.

Step S611, the information that network section management function is carried according to inquiry request, lookup meets the requirements Objective network section (by network section B exemplified by), and by network cut into slices B information be supplied to service Network is cut into slices.
