Abstract: A wireless communication method for use in an access and mobility management function is disclosed. The wireless communication method comprises transmitting, to a policy control function, PCF, allowed network slice selection assistance information, NSSAI, associated with a wireless terminal.

Abstract: This disclosure relates to a method for effectuating data traffic routing influence for a relocated application service in a core network of a communication system. In an embodiment, the core network may include a communication session control node and an application service node. The method may include transmitting, by the communication session control node, a message to the application service node for notifying a relocation triggering event. The relocation triggering event triggers the application service node to relocate an application service provided to a user equipment in a pre-established communication session from a previous application hosting server to a new application hosting server outside of the mobile core network. The method may further include receiving, by the communication session control node, a relocation information from the application service node such that the communication session control node may reconfigure and modify the data traffic routing for the relocated application service.
