Method and apparatus for energy conservation in a communication system
First Claim
1. A radio system for communicating information to one or more portable radio devices having a first operational mode and a second operational mode, the radio system comprising:
- a central control terminal comprising;
information index means for generating an encoded indexed information message having an index portion and an information portion, wherein the information portion comprises at least one information field and the index portion comprises, on a one to one basis, at least one corresponding pointer indicating a location of the corresponding information field; and
transmission means coupled to said information index means for transmitting the encoded indexed information message; and
the one or more portable radio devices, each comprising;
a receiver for receiving the index portion and the information portion of the encoded indexed information message;
a controller having an authorized information field list stored therein, said controller coupled to said receiver for decoding the encoded indexed information message, for processing the index portion and the information portion of the decoded indexed information message, and for generating a mode control schedule determined by the index portion and the authorized information field list; and
mode control means, coupled to said controller, for controlling the first and second operating modes of the portable radio device according to the mode control schedule.

Abstract
A portable radio device (106) has a first operational mode and a second operational mode, and includes a receiver (314), a controller (315), and a mode control device (350). The receiver (314) receives an indexed information message. The controller (315) stores an authorized information field list and is coupled to the receiver (314). The controller (315) decodes the indexed information message, generates an index portion of the decoded indexed information message, and generates a mode control schedule determined by the index portion and the authorized information field list. The mode control device (350) is coupled to the controller (315) for controlling the first and second modes of the portable radio device according to the mode control schedule.

20. In a radio communication system having one or more portable radio devices and information messages intended for reception by the portable radio devices, a method for controlling, during an information portion of the information messages, first and second modes of a portable radio device, the method comprising the steps of:
-
generating, within a system controller, a message including an authorized information field list intended for the portable radio device; transmitting, from the system controller, the message intended for the portable radio device; receiving the message at the portable radio device; storing the authorized information field list within the portable radio device; controlling the first and second operational modes of the portable radio device during the reception of an information portion of a subsequently received indexed information message in response to an index portion of the subsequently received indexed information message and the stored authorized information field list, wherein the information portion comprises at least one information field and the index portion comprises, on a one to one basis, at least one corresponding pointer indicating a location of the corresponding information field, said step of controlling further comprising the steps of; receiving an indexed information message comprising an index portion and an information portion; determining from the index portion of the indexed information message and the authorized information list a mode control schedule; and controlling the first and second modes of the portable radio device according to the mode control schedule.
