METHOD AND SYSTEM FOR HANDOVER AND DOMAIN TRANSFER IN A TELECOMMUNICATIONS SYSTEM |
摘要 |
The invention relates to a method and a system for a packet switched handover and a domain switch for a wireless communications network comprising a user equipment (UE), a packet switched domain (701) and a circuit switched domain (702). The packet switched domain (701) comprises a source packet system (703) and a target packet system (704). The target packet system (704) comprises a radio access network (RAN1) portion (target BTS; BSC) and a first core network (CN1) portion (target SGSN). The circuit switched domain (702) comprises a second radio access network (RAN2) portion (target BTS; BSC) and a second core network (CN2) portion (MSC). The user equipment (UE) performs an attachment/registration/update procedure towards the second core network (CN2) portion and/or a signalling connection establishment before the handover between the source packet system (703) and the target packet system (704) is executed.
