Method for mobility management in a system architecture supporting mobility between different access systems |
摘要 |
A method for Mobility Management MM in a system architecture supporting mobility between different access systems having separate Core Network CN-level MM entities while using common MM Area, the method comprising a step of: when a User Equipment UE leaves the coverage of a first one of the access systems where it is in a Non Radio Connected state as seen from Radio Access Network RAN, but seen in Connected State from CN-level MM entity, for the coverage of a second one of the access systems where it is in Idle state as seen from CN-level MM entity, putting the UE into Idle state as seen from CN-level MM entity of said first access system. |

1. A multimode User Equipment (UE) comprising:
a transmitter configured to support access to a Universal Mobile Telecommunications System (UMTS) and a Long Term Evolution (LTE) system; and a processor electrically coupled to the transmitter, the processor configure to, set the UE to a Universal Terrestrial Radio Access Network (UTRAN) Registration Area Paging Channel (URA-PCH) state, and issue, via the transmitter, a Tracking Area Update associated with the UE in the URA-PCH state roaming from the UMTS system to the LTE system, wherein when the UE is set to the URA-PCH state, paging of the UE is required to re-establish a radio connection to the UMTS and the Tracking Area Update enables the LTE system to know the location of the UE. |
