Abstract
Disclosed is a method for detachment of a mobile set including receiving, by a service node of a communication system, a detachment request from the mobile set, transmitting, by the service node of the communication system, a delete context request message for the mobile set to a first service node of another communication system, and transmitting, by the service node, a detachment indicator to a second service node of the another communication system, wherein the service node of the communication system is different from the service node of the another communication, wherein both the service node of the communication system and the first service node of the another communication system store context information related to the mobile set, and wherein the mobile set moves between the service node of the communication system and the first service node of the another communication system without an area updating.
