MOBILE COMMUNICATIONS METHOD AND MOBILE MANAGEMENT NODE

摘要

The present invention provides a handover method comprising: a step (A) wherein an MME sends a "Forward Reloc Req" to an SGSN; a step (B) wherein if the MME, after detecting that PS bearer settings have been refused in the SGSN, detects that handover of voice communications from a E-UTRAN to a UTRAN/GERAN has been completed, the MME opens a PS bearer used for UE#1 voice communications and packet communications in a mobile transmission network housing the E-UTRAN.
