Abstract  Abstract

PROBLEM TO BE SOLVED: To enable handover of a mobile node from E-UTRAN to UTRAN in a scenario in which SMS is a unique service to the mobile node.SOLUTION: A method establishes a signaling connection to exchange SMS in a handover destination network. Since data connection is not used, radio resources can be saved by avoiding data connection in the handover destination network. MME determines whether data connection is established in a handover destination UTRAN. In order to avoid establishment of data connection, SGSN and UE are instructed to set the corresponding PDP contexts on the data connection to Save state. Further, an embodiment relates to an improved SMS distribution for UE of an IDLE mode for activating ISR in order to avoid involvement of a MSC server. Instead, only nodes of a packet switched domain are involved.SELECTED DRAWING: Figure 31
