Abstract

A method of providing a packetized data transmission service to a mobile terminal (108) in a spread spectrum communication network (100), includes: at a transmitter (102), broadcasting an indication message to a cell on a downlink broadcast channel (114), the indication message providing notification of an available packetized data transmission service intended for the mobile terminal (108); at the mobile terminal (108), monitoring the broadcast channel (114) for the indication message, and upon receipt, acknowledging detection of the indication message to the transmitter (102) on an uplink contention channel (116); and at the transmitter (102), upon contention completion, transmitting packetized data transmission service configuration information to the mobile terminal (108) on the broadcast channel (114).

Claims5

Dependent claims

A method implemented in a spread spectrum communications system for providing a packetized data transmission service, the method comprising:

broadcasting from a base station to a cell an indication of the packetized data transmission service on a downlink channel, the indication comprising a notification of the packetized data transmission service;
monitoring, at a user equipment, the downlink channel for the indication of the packetized data transmission service from the base station,
transmitting from the user equipment to the base station an acknowledgement of detection of the indication;
transmitting packetized data transmission service configuration information from the base station to the user equipment on the downlink channel;
transmitting from the base station to the user equipment control information for the packetized data transmission service on a downlink shared control channel;
monitoring, at the user equipment, the downlink shared control channel for the control information for the packetized data transmission service;
transmitting data for the packetized data transmission service from the base station to the user equipment on a downlink shared data channel;
reporting from the user equipment to the base station channel quality information;
and
transmitting from the base station to the user equipment an indication of termination of the packetized data transmission service on a downlink shared control channel,
wherein the user equipment has two states that comprise an active state to monitor the downlink channel and an inactive state, and
wherein the user equipment utilizes the packetized data transmission service configuration information to monitor the downlink shared control channel for the control information for the packetized data transmission service.
