The network selection access information may be sent directly to the first device by the local network or indirectly to the first device by the local network, e.g., the local network sends the network selection access information to the second device and the second device sends the network selection access information to the first device. The second device comprises a device of a service level agreement (Service Level Agreement, SLA) set up and negotiation system. The SLA establishment negotiation system provides a negotiation communication channel between networks for each network, so that the establishment of the negotiation communication channel between each network is not required.

Further, after step 401, the method may further include: the terminal accesses the target local network according to the network selection access information, and the step is optional.

Specifically, the terminal selects a local network according to the network selection access information and accesses the local network. For example, when the terminal searches for a local network in the vicinity that satisfies the network selection access information, the terminal selects and accesses the local network, that is, the target local network.

A local network satisfying network selection access information (the local network may be referred to as a target local network) means that one or more network parameters of the local network match with corresponding one or more of the network selection access information, i.e. the terminal accesses the target local network in case at least one parameter of the target local network matches with a parameter of the local network in the network selection access information. For example, the identity of the home network of home network a is the same as the identity of the home network to be selected in the network selection access information.

Alternatively, when the terminal wants to use a certain service, if it is searched that a service identifier (service ID) broadcasted by a certain local network is the same as a service identifier supported by the local network, the local network is said to satisfy the network selection access information.

And 13, the 3rd party SP NF sends the network selection access information of the nesting network to the UE.

Optionally, the UE sends a request message to the 3rd party SP NF through the above channel, for requesting network selection access information of the nesting network.

And 14, the UE selects a nesting network according to the network selection access information and accesses the network.

For example, when the UE searches that there is a nesting network meeting the network selection access information, the UE selects and accesses the nesting network. The network meeting the requirement of the network selection access information refers to that one or more network parameters of the network are matched with one or more corresponding items of the network selection access information. For example, the identifier of the nesting network of hosting network A is the same as the identifier of a nesting network that can be selected in the network selection access information of the nesting network.

Optionally, when the UE wants to use a certain service, if the service ID broadcasted by searching a certain nesting network is the same as the identifier of the service that can be supported by the nesting network, the nesting network is said to satisfy the network selection access information of the nesting network.

Optionally, the 3rd party SP NF sends a request message to the SP SLANF for requesting to acquire the network selection access information of the nesting network. Optionally, the UE sends a request message to the 3rd party SP NF through the above channel, for requesting to obtain the network selection access information of the serving network.

And 36, selecting one nesting network by the UE according to the network selection access information of the nesting network and accessing the nesting network.
