Method for providing communications to a communication device in a radio communication system
First Claim
1. In a communication system that includes a system controller, a plurality of base sites, and a communication device, the plurality of base sites serving respective service coverage areas, the service coverage areas being grouped into a plurality of location areas, a method for the system controller to provide packet data communications to the communication device, the method comprising the steps of:
- a) receiving a registration message from the communication device via a first base site of the plurality of base sites;
b) affiliating the communication device with the first base site and a first location area of the plurality of location areas that includes a service coverage area of the first base site;
c) receiving a packet data communication intended for the communication device to produce a received communication;
d) determining whether the received communication was received within a first predetermined period of time after a previous packet data communication involving the communication device; and
e) when the received communication was received within the first predetermined period of time, transmitting at least a first portion of the received communication to the communication device via the first base site.

Abstract
A communication system (100) employs a method for providing communications to a communication device (e.g., 120) located in the communication system. The communication device (120) transmits a registration message to a system controller (101) via a first base site (104). The system controller then affiliates the communication device with the first base site and a location area (150) that includes a service coverage area (134) of the first base site. When the system controller receives a communication (e.g., a packet data communication) for the communication device, the system controller determines whether the communication was received within a predetermined period of time after a previous communication involving the communication device. When the communication was received within this period of time, the system controller transmits at least a portion of the communication to the communication device via the first base site; otherwise, the system controller pages the communication device via the base sites (103-106) serving the location area.

17. In a communication system that includes a system controller, a plurality of base sites, and a communication device, the plurality of base sites serving respective base site service coverage areas, the base site service coverage areas being grouped into a plurality of location areas, a method for the communication device to receive communications from the system controller, the method comprising the steps of:
-
a) transmitting a first registration message to the system controller via a first base site of the plurality of base sites upon entering a first location area of the plurality of location areas; b) determining whether a first page has been received from the system controller, the first page indicating that the system controller has a communication for the communication device; and c) when a first page has been received and the communication device is not actively participating in a communication, transmitting a supplemental registration message to the system controller upon entering a base site service coverage area during a first predetermined period of time after receipt of the first page. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
