METHOD OF IMPROVING MOBILITY MANAGEMENT CAPABILITIES AT REGISTRATION ZONE, AND COLOR CODE BORDERS IN A WIRELESS COMMUNICATIONS SYSTEM

摘要

In a 3G CDMA2000 IS-2000 wireless communications system, a base station at the border between two packet zones, transmits an Extended System Parameters message that includes the identity of a primary packet zone supported by that base station as well as the identities other secondary adjoining packet zones supported by that base station. When transiting the borders between packet zones, a dormant mobile terminal will not request a reconnection until its current packet zone is no longer listed in the Extended System Parameters message received from the base station in the cell in which it is currently located. Thus, the mobile terminal will not need to repeatedly initiate a reconnection in each packet zone as moves back and forth across packet zone borders. Alternatively, the Extended System Parameters message includes a special value packet zone identity that is interpreted by the receiving mobile terminal to mean "no change." Both of these alternatives are also applicable to color code and registration zone domains.
