Abstract
Abstract A method for an RF base station (105) to transmit an emergency message to a selective call receiver (104). The base station (105) receives incoming messages that are to be transmitted to selective call receivers, some of which incoming messages are emergency messages that include an emergency code, such as "911". The base station (105) creates a shortened emergency message by removing the emergency code from an incoming emergency message, and sends the shortened emergency message to a selective call receiver (104), along with an alert instruction for actuating a priority alert in the selective call receiver (104).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
102 words
In an RF communication system having a base station that receives incoming messages for transmission to selective call receivers, a method for transmitting emergency messages to the selective call receivers, comprising: at the base station: a) receiving incoming messages that are to be transmitted to selective call receivers, wherein some of the incoming messages are emergency messages that include an emergency code; b) removing the emergency code from the emergency messages to provide shortened emergency messages; and c) transmitting the shortened emergency messages along with alert instructions for activating a priority alert in selective call receivers that receive a shortened emergency message.
Claim 2
Dependent Claim
102 words
In an RF communication system having a base station that receives incoming messages for transmission to selective call receivers, a method for transmitting emergency messages to the selective call receivers, comprising: at the base station: a) receiving incoming messages that are to be transmitted to selective call receivers, wherein some of the incoming messages are emergency messages that include an emergency code; b) removing the emergency code from the emergency messages to provide shortened emergency messages; and c) transmitting the shortened emergency messages along with alert instructions for activating a priority alert in selective call receivers that receive a shortened emergency message.
Claim 3
Dependent Claim
14 words
A method as set forth in claim 1 wherein the emergency code is 911.
Claim 4
Dependent Claim
26 words
A method as set forth in claim 1 further including, prior to step b), scanning each incoming message to detect the presence of an emergency code.
Claim 5
Dependent Claim
42 words
A method as set forth in claim 1 wherein each message is transmitted with an address code word identifying a selective call receiver to which a transmitted message is addressed, and wherein the alert instructions are appended to the address code word.
Claim 6
Dependent Claim
35 words
A method as set forth in claim 1 wherein messages are transmitted according to a protocol that includes an address field, and wherein an alert instruction comprises a priority address transmitted within the address field.
Claim 7
Dependent Claim
33 words
A method as set forth in claim 1 wherein messages are transmitted according to a protocol that includes a vector field, and wherein an alert instruction comprises data transmitted within the vector field.
Claim 8
Dependent Claim
108 words
In an RF communication system having a base station that receives incoming messages for transmission to selective call receivers, a method for transmitting emergency messages to the selective call receivers, comprising: at the base station: a) receiving incoming messages that are to be transmitted to selective call receivers, wherein some of the incoming messages are emergency messages that include "911"; b) scanning incoming messages to detect the presence of "911"; c) removing "911" from the emergency messages to provide shortened emergency messages; and d) transmitting the shortened emergency messages along with alert instructions for activating a priority alert in selective call receivers that receive a shortened emergency message.
Claim 9
Dependent Claim
