1. In a system comprising (i) a calling mechanism operable in a calling mechanism on-hook state and operable in a calling mechanism off-hook state, and (ii) an intermediary device operable in an intermediary device on-hook state and operable in an intermediary device offhook state, a method comprising:
- switching the calling mechanism to the calling mechanism off-hook state, and responsively switching the intermediary device to the intermediary device off-hook state;
thereafter, using the calling mechanism to dial an emergency number, and responsively establishing a communication via the intermediary device between a Public Safety Answering Point (PSAP) and the calling mechanism;
after establishing the communication and before the intermediary device sends a civic address along with a parameter type value to identify that the civic address is being communicated to the PSAP, switching the calling mechanism to the calling mechanism on-hook state; and
after switching the calling mechanism to the calling mechanism on-hook state, sending the civic address from the intermediary device to the PSAP, and thereafter switching the intermediary device to the intermediary device on-hook state,wherein the civic address includes a predetermined number of bytes of data, a first number of bytes representing a street number and street name, a second number of bytes representing a street type, a third number of bytes representing a postal mailing code,wherein the civic address includes twenty-one bytes of data,wherein the first number of bytes are fourteen bytes of data of the twenty-one bytes of data that represent the street number and street name,wherein the second number of bytes are two bytes of data of the twenty-one bytes of data that represent the street type,wherein the third number of bytes are five bytes of data of the twenty-one bytes of data that represent the postal mailing code, andwherein sending the civic address includes sending the fourteen bytes first, then the two bytes of data, and then the five bytes of data.

Abstract
Methods and an intermediary device are disclosed for sending a civic address and other information from the intermediary device to an apparatus associated with a predefined number (such as Public Safety Answering Point). The civic address may include a street number, street name, street type, and postal mailing code, all of which may be associated with a wireless calling access line assigned to the intermediary device. A calling mechanism (e.g., a telephone) operating in an off-hook state initiates a communication with the apparatus. The intermediary device may enter the off-hook state in response to the calling mechanism entering the off-hook state. The intermediary device can continue to operate in the off-hook state so as to send the civic address to the apparatus (e.g., a PSAP) even if the calling mechanism switches to an on-hook state prior to the civic address being sent to the apparatus.

1. In a system comprising (i) a calling mechanism operable in a calling mechanism on-hook state and operable in a calling mechanism off-hook state, and (ii) an intermediary device operable in an intermediary device on-hook state and operable in an intermediary device offhook state, a method comprising:
-
switching the calling mechanism to the calling mechanism off-hook state, and responsively switching the intermediary device to the intermediary device off-hook state; thereafter, using the calling mechanism to dial an emergency number, and responsively establishing a communication via the intermediary device between a Public Safety Answering Point (PSAP) and the calling mechanism; after establishing the communication and before the intermediary device sends a civic address along with a parameter type value to identify that the civic address is being communicated to the PSAP, switching the calling mechanism to the calling mechanism on-hook state; and after switching the calling mechanism to the calling mechanism on-hook state, sending the civic address from the intermediary device to the PSAP, and thereafter switching the intermediary device to the intermediary device on-hook state, wherein the civic address includes a predetermined number of bytes of data, a first number of bytes representing a street number and street name, a second number of bytes representing a street type, a third number of bytes representing a postal mailing code, wherein the civic address includes twenty-one bytes of data, wherein the first number of bytes are fourteen bytes of data of the twenty-one bytes of data that represent the street number and street name, wherein the second number of bytes are two bytes of data of the twenty-one bytes of data that represent the street type, wherein the third number of bytes are five bytes of data of the twenty-one bytes of data that represent the postal mailing code, and wherein sending the civic address includes sending the fourteen bytes first, then the two bytes of data, and then the five bytes of data. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. An intermediary device comprising:
-
a communication unit having a first interface for interfacing with a first network that provides connectivity to a calling mechanism, and a second interface for interfacing with a second network that provides connectivity to an apparatus associated with a predefined number; a processor; and data storage, wherein the data storage contains program logic executable by the processor to (i) detect the calling mechanism dialing the predefined number, and responsively invoke the communication unit to establish a communication with the apparatus associated with the predefined number; and
(ii) after the calling mechanism switches to an on-hook state, invoke the communication unit to send a civic address to the apparatus associated with the predefined number, the civic address including a predetermined number of bytes of data, a first number of bytes representing a street number and street name, a second number of bytes representing a street type, a third number of bytes representing a postal mailing code,wherein the civic address includes twenty-one bytes of data, wherein the first number of bytes are fourteen bytes of data of the twenty-one bytes of data that represent the street number and street name, wherein the second number of bytes are two bytes of data of the twenty-one bytes of data that represent the street type, wherein the third number of bytes are five bytes of data of the twenty-one bytes of data that represent the postal mailing code, and wherein sending the civic address includes sending the fourteen bytes first, then the two bytes of data, and then the five bytes of data. - View Dependent Claims (9, 10)

11. In an intermediary device residing in a communication path between a calling mechanism and a wireless local loop, a method comprising:
-
detecting the calling mechanism dialing a predefined number, and responsively establishing a communication between the calling mechanism and an apparatus associated with the predefined number; and after the calling mechanism has switched to an on-hook state, sending frequency shift keying (FSK) signals to the wireless local loop for transmission, in turn, to the apparatus associated with the predefined number, wherein the FSK signals represent a civic address associated with the calling mechanism and a parameter type value to identify that the civic address is being communicated in the FSK signals, wherein the civic address comprises an address selected from the group consisting of (i) a street number, (ii) a street name, (iii) a street type, and (iv) a postal mailing code, wherein the civic address includes a predetermined number of bytes of data, a first number of bytes representing a street number and street name, a second number of bytes representing a street type, a third number of bytes representing a postal mailing code, wherein the civic address includes twenty-one bytes of data, wherein the first number of bytes are fourteen bytes of data of the twenty-one bytes of data that represent the street number and street name, wherein the second number of bytes are two bytes of data of the twenty-one bytes of data that represent the street type, wherein the third number of bytes are five bytes of data of the twenty-one bytes of data that represent the postal mailing code, and wherein sending the civic address includes sending the fourteen bytes first, then the two bytes of data, and then the five bytes of data. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
