Abstract

A method and apparatus for reliably delivering information service messages (300) from a central terminal (106) to a communication receiver (118) in a wireless message communication system (100). The communication receiver (118) receives information service messages including an information group identifier and data updates corresponding thereto. The communication receiver (118) receives disable messages (400) including an expiration time. The communication receiver (118) decodes received data updates (306) when the information group identifier (226) is determined as enabled. It does not decode received data updates (306) when the information group identifier (220) is determined as disabled (222). The communication receiver (118) determines enabled status as a default condition, and determines disabled status when a disable message (400) was received. The received disable message (400) includes an expiration time (408) for maintaining the information group identifier (220) disabled until the expiration time (224) expires and then enables the information group identifier (220).

Claims

1. A method in a communication receiver, the method comprising the steps of:

(a) receiving wireless transmissions comprising information service messages, the information service messages comprising an information group identifier and information data updates corresponding with the information group identifier;

(b) receiving wireless transmissions comprising disable code messages, the disable code messages comprising a destination address of a communication receiver, an information group identifier, and a disable code expiration time;

(c) decoding received information data updates corresponding with the information group identifier when the information group identifier is determined as having an enabled status, and

not decoding the received information data updates corresponding with the information group identifier when the information group identifier is determined as having a disabled status; and

(d) determining that an information group identifier has an enabled status as a default condition, and that the information group identifier has a disabled status when a disable code message was received, where the received disable code message included;

a destination address matching a predetermined address for the communication receiver, and

an information group identifier to be disabled, and

a disable code expiration time for maintaining the information group identifier disabled until the disable code expiration time expires at which time the communication receiver automatically enables the information group identifier.

2. The method of claim 1, further comprising the steps of:

maintaining a reception count corresponding to reception of information service messages; and

disabling reception of information service messages when the reception count exceeds a predetermined threshold amount.

3. The method of claim 2, wherein the information service messages include message transmission information representative of a number of information service messages transmitted over a time interval, and wherein the predetermined threshold amount is the message transmission information.

4. The method of claim 2, wherein the predetermined threshold amount is a value computed by the communication receiver as a function of a received disable code expiration time, and wherein the reception count is maintained by the communication receiver as a function of an off time for the communication receiver.

5. The method of claim 2, wherein the predetermined threshold amount is a value computed by the communication receiver as a function of receptions of the information service messages.

6. A selective call receiver comprising:

a paging receiver for receiving messages including information service messages and disable code messages, the information service messages comprising an information group identifier and information data updates corresponding with the information group identifier, and the disable code messages comprising a destination address of a communication receiver, an information group identifier, and a disable code expiration time information;

an address memory for storing predetermined address information;

a status memory for storing status information comprising enable/disable status information and disable code expiration time information associated with at least one predetermined information group identifier; and

a controller electrically coupled to the paging receiver, the address memory, and the status memory for

decoding the received information data updates corresponding with the information group identifier when the information group identifier is determined as having an enabled status, and

not decoding the received information data updates corresponding with the information group identifier when the information group identifier is determined as having a disabled status, where the controller determines that an information group identifier has an enabled status as a default condition, and that the information group identifier has a disabled status when a disable code message was received, where the received disable code message included;

a destination address matching a predetermined address information for the selective call receiver, and

an information group identifier to be disabled, and

a disable code expiration time for maintaining the information group identifier disabled until the disable code expiration time expires at which time the communication receiver automatically enables the information group identifier.

7. The selective call receiver of claim 6, wherein the controller maintains a reception count corresponding to reception of information service messages, and the selective call receiver disables reception of information service messages when the reception count exceeds a predetermined threshold amount.

8. A communication system comprising:

paging transmitting means for wireless transmitting messages including information service messages and disable code messages, the information service messages comprising an information group identifier and information data updates corresponding with the information group identifier, and the disable code messages comprising a destination address of a communication receiver, an information group identifier, and a disable code expiration time information; and

at least one selective call receiver, each one of the at least one selective call receiver comprising;

a paging receiver for receiving the messages including the information service messages and the disable code messages;

an address memory for storing predetermined address information;

a status memory for storing status information comprising enable/disable status information and disable code expiration time information associated with at least one predetermined information group identifier; and

a controller electrically coupled to the paging receiver, the address memory, and the status memory for

decoding the received information data updates corresponding with the information group identifier when the information group identifier is determined as having an enabled status, and

not decoding the received information data updates corresponding with the information group identifier when the information group identifier is determined as having a disabled status, where the controller determines that an information group identifier has an enabled status as a default condition, and that the information group identifier has a disabled status when a disable code message was received, where the received disable code message included;

a destination address matching a predetermined address information for the selective call receiver, and

an information group identifier to be disabled, and

a disable code expiration time for maintaining the information group identifier disabled until the disable code expiration time expires at which time the communication receiver automatically enables the information group identifier.

9. The communication system of claim 8, wherein the information service messages include message transmission information representative of a number of information service messages transmitted over a time interval, and wherein the controller maintains a reception count corresponding to reception of information service messages, and wherein each of the at least one selective call receiver disables reception of information service messages when the reception count exceeds a threshold set by a received message transmission information.
