For a better understanding of the present invention, a CSG selection mode setting will be explained first.

The HNB is a cell in which a small Evolved Universal Terrestrial Radio Access (E-UTRA) or other Access network is deployed in a local area, an office or a similar small-range area, and is connected to a core network through a wired Access device to provide Access service for a user, thereby reducing Access cost and improving network coverage. One HNB does not serve all users, but only some specified users, and this service also requires that the user deploying the base station can control the user identities allowed to access the base station. CSG thus refers to a group of subscribers that are allowed to access one or more specific cells, i.e., cells supported by HNBs.

A terminal accesses a CSG cell and needs to determine a CSG selection mode, which is a mode for selecting an access CSG by the terminal and is generally divided into automatic selection and manual selection. The automatic selection means that the terminal automatically searches local selectable CSG when initiating CSG access, and selects the most suitable CSG to provide service for the user; the manual selection means that the user needs to select the CSG to receive the service from the currently searchable CSGs in the terminal, and the manual selection can be implemented by setting a corresponding setting on a terminal interactive interface. The CSG selection mode is one of capabilities required by the terminal, and particularly in some special scenarios of the HNB, when the terminal has a certain need for the HNB network selection mechanism for reasons of cost, security, and the like, the function will play a more obvious role. The setting of the CSG selection mode is currently implemented by a terminal setting function, and the setting is mainly user behavior, that is, a user requests the terminal to execute an automatic selection mode according to will, or a manual selection mode selected by the user after searching the CSG network.

The Universal Subscriber Identity Module USIM (Universal Subscriber Identity Module) is a continuation and progress of a Subscriber Identity Module SIM card used in a Universal Mobile Telecommunications System UMTS (Universal Mobile Telecommunications System) network, is used for storing Subscriber Identity information and personal data, ensures the security of accessing a Mobile network service, and can perform Subscriber identification and Subscriber authorization when a Subscriber accesses the Mobile network service by using necessary functions and data, thereby realizing the requirement that the Mobile network can represent and identify Subscriber applications. The USIM may influence the CSG selection in a certain manner, for example, a list of CSGs allowed to be selected is preset in the USIM, and when the terminal is required to select a CSG in the list in the automatic selection mode, only the CSG in the list is selected, but other CSGs are not allowed to be selected. The USIM is connected with an operator, network information which is provided by the operator and has more optimized quality and more economic cost can be obtained, the operator sets a CSG selection mode and designates a CSG selection strategy for a user in a customer service mode, the CSG network requirements of terminal services can be better met, and the user experience is improved.

The universal subscriber identity module application toolkit USAT (USIM application toolbox) protocol is a service mechanism supported in the USIM, and the USAT allows USIM applications to interact and operate with terminals supporting this mechanism, so that the USIM can actively request the terminals to perform a certain operation.

Therefore, embodiments of the present invention will provide a CSG selection mode setting method, USIM, terminal, device and medium, which implement a method for an operator to participate in providing a CSG selection mode and a CSG selection policy that satisfy business requirements based on interaction between the USIM and the terminal through USAT, and can control the terminal to execute a specified CSG selection mode and execute a corresponding CSG selection policy without user intervention, thereby enhancing initiative of the USIM in CSG selection management, because the USIM can implement remote update and management with a business platform, and is convenient to update the policy in time according to real-time change of business requirements, therefore feasibility of managing selection based on the USIM CSG is stronger, which can satisfy more complex or special requirements in scenes requiring quality of service management, coverage optimization management, etc., and is also helpful for improving business capability and improving service capability of a user; the following provides a detailed description of embodiments of the invention.
