A selective call device (130) having a receiver (204) that receives a selective call signal with an address (312), a formatting message (406), and a related message (408). A processor (214) correlates a recovered address with a predetermined address in the selective call device (130) and determines selection of the selective call device (130). A decoder (212) decodes the formatting message (406) and the related message (408) contained in the selective call signal in response to the processor (214) determining selection of the selective call device. An information display (228) presents at least a portion of the related message (408) in accordance with a format determined at least in part by the formatting message (406).

Selective call message formatting

An updateable message encoder/transmitter (100) has a processor (109) for encoding messages and message updates. A message includes an origination time (191), a version number (410) and an update lifetime indicator (424), and a message update includes the origination time (191) and the version number. A transmitter (120) broadcasts the message and the message update message receiver/decoder (130) receives the message and the message update, a processor (212) processes the message to determine when the message update is being received. The processor checks the update lifetime indicator of the message indicated by the message update to determine if the message to which the message update is intended can be updated. A comparator compares the origination time of the message with the origination time of the message update to determine if the message update is an out-of-sequence message update.

System and method for including origination time and update lifetime

A selective call device (130) has a receiver (204) for receiving a selective call signal including an address (312). An address correlator (214) coupled to a decoder (212) determines that the selective call signal is directed thereto and determines whether the selective call signal includes an update command (400, 500). The update command includes a major version number (406, 506), topic numbers associated with sub-message(s) stored in the selective call device, update data associated with each topic number for updating the sub-messages, and minor version numbers (427, 527) associated with each topic number. The major version number is incremented when a sub-message template is changed. Minor version numbers are incremented after each update. The selective call device updates a sub-message with update data only if the update command includes a current major version number and an incremented minor version number.

Reliably updating an information service message

A selective call device (130) has a receiver (204) for receiving a selective call signal including an address (312) and a topic sub-address (504) indicative of a subscribed information, a processor (212, 214) for correlating the address (312) in the selective call signal to determine when the selective call signal is directed thereto, a decoder (212), in response to the processor (212, 214) determining that the selective call signal is directed thereto, for decoding the topic sub-address (504) to determine when the selective call signal includes the subscribed information, and a battery saver, coupled to the receiver (204), for initiating battery saving when the address (312) does not correlate with a predetermined address of the selective call device (130) and for initiating battery saving when the topic sub-address (504) is absent from the selective call signal.

Selective call device and method for battery saving during information

A technique is for receiving variable length messages in a selective call receiver (68) having a processor (110) coupled to a memory element (86). The selective call receiver (68) is configured to receive a signal transmitted in a standard protocol format comprising an address portion (14) and a message portion (16). First, second, third, and fourth configuration values are stored within the selective call receiver (68) from which determinations are made, respectively, whether the selective call receiver (68) is permitted to process sub-address information (22, 24) included within the message portion, whether said selective call receiver (68) is permitted to receive a particular sub-address included in the message portion, whether said selective call receive (68) is permitted to process a processor command (26) included in the message portion, and whether said selective call receiver (68) is permitted to receive and process a particular processor command included in the message portion.

Embedded protocol

A messaging system, having a transmitter (202) for transmitting information service messages to selective call units (SCU's) (122), receives displayable information from a service provider, and creates a message having an address field (504) and data field (508). The address field (504) includes an address assigned to at least one SCU (122), and the data field (508) includes the displayable information. A portion of the displayable information is defined as at least one subaddress field (510, 514). The at least one subaddress field (510, 514) is used by the at least one SCU (122), when receiving the message from the messaging system, for determining whether a portion of the displayable information is to be processed.
