Embodiment Construction

[0013] In the described first embodiment, it is assumed for illustration purposes that the mobile terminal and wireless system operate according to the CDMA2000 IS-2000 standard for data transmission. In this embodiment, a base station in a cell on the border between two different packet areas simultaneously supports multiple packet areas of adjacent domains. figure 1 A domain diagram with three illustrative grouping zones 1, 2 and 3 is shown. Numbers in a circle representing the coverage area of ​​a cell indicate the packet area or areas supported by that cell. Thus, base stations in border cells 101 and 102 in packet zone 1 and base stations in cells 103 and 104 in packet zone 2 simultaneously support packet zones 1 and 2 as indicated by marks 1 and 2 in the circles. Similarly, the border cell between packet area 1 and packet area 3, and the border cell between packet area 2 and packet area 3 all support their respective adjacent packet areas. Likewise, each cell 105, 106,...

Abstract

In the 3G CDMA2000 IS-2000 wireless communication system, a base station on the boundary between two packet areas transmits an extended system parameter message, which contains the identification of the main packet area supported by the base station and the information supported by those base stations. IDs of other adjacent sub-packet areas. When crossing a boundary between packet areas, a suspended mobile terminal will not request reconnection until its current packet area is no longer listed in the Extended System Parameters message received from the base station in the cell it is currently located in. Therefore, when the mobile terminal is moving forward and backward across packet zone boundaries, it will not need to repeatedly initiate reconnection in each packet zone. Optionally, the extended system parameter message includes a specific value packet area identifier, which is interpreted by the receiving mobile terminal as meaning "no change". These options also apply to color coding and registration areas.

Description

technical field [0001] The present invention relates to wireless communications, and more particularly to the repeated reconnection and / or re-register. Background technique [0002] Each wireless base station, such as a third generation (3G) CDMA2000 base station operating in accordance with the IS-2000 series of standards, broadcasts a Packet Zone Identifier (PZID). The PZID is used to identify different logical zones in the wireless network. When a suspended mobile terminal moves into a coverage area of ​​a PZID that is not in the internally stored recently visited list, the mobile terminal will normally perform a packet zone attach to move the data session to the new packet zone. A mobile terminal on a packet zone boundary may "ping-pong" between the two zones, creating an excessive number of reconnections. [0003] In the current state of the art, a time-based lag is used. When a mobile terminal becomes inactive after sending or receiving data, only the PZID of the ...
