Techniques for accessing a core network via access points and gateway functions are provided. For example, a method comprises: determining one or more candidate gateway functions for accessing the core network via the access point; transmitting, to the one or more candidate gateway functions or to a core network function, a request for use of the one or more gateway functions to access the core network; and receiving, from the gateway function or from the core network function, a request response per candidate gateway function, the request response being configured to indicate whether the access to the core network via the respective gateway function is rejected and, in the case of rejection, to indicate a cause of rejection. The method may be performed by the terminal device (e.g., a user equipment, UE). Corresponding methods that can be performed by a network device are also provided.
