Abstract

Method of communicating between a first wireless phone and a second wireless phone A method of communicating between a first wireless phone (A) and a second wireless phone (B), each of said first and second wireless phones comprising a wireless transceiver for exchanging data using a signaling protocol, said method comprising the steps of: initiating a direct communication between the two wireless phone via a first stimulus on the first wireless phone and a second stimulus on the second wireless phone, configuring the first wireless phone with a first predefined IP address (IP_A) and a first signaling protocol identifier (SIP_A), and the second wireless phone with a second predefined IP address (IP_B) and a second signaling protocol identifier (SIP_B), the first, respectively second, phone knowing the second, respectively first, IP address, the second, respectively first, signaling protocol identifier and a predefined wireless network identifier (SSID), establishing a direct communication between the two wireless phones using their wireless transceivers and the signaling protocol on the basis of the first and second predefined IP addresses, the first and second predefined signaling protocol identifiers and the predefined wireless network identifier.

Claims

1. A method of communicating between a first wireless phone (A) and a second wireless phone (B), each of said first and second wireless phones comprising a wireless transceiver for exchanging data using a signaling protocol, said method comprising the steps of:

initiating a direct communication between the two wireless phone via a first stimulus on the first wireless phone and a second stimulus on the second wireless phone,

configuring the first wireless phone with a first predefined IP address (IP_A) and a first signaling protocol identifier (SIP_A), and the second wireless phone with a second predefined IP address and a second signaling protocol identifier (SIP_B), the first, respectively second, phone knowing the second, respectively first, IP address, the second, respectively first, signaling protocol identifier and a predefined wireless network identifier (SSID),

establishing a direct communication between the two wireless phones using their wireless transceivers and the signaling protocol on the basis of the first and second predefined IP addresses, the first and second predefined signaling protocol identifiers and the predefined wireless network identifier.

2. A method as claimed in claim 1, wherein the wireless transceivers are WiFi transceivers.

3. A method as claimed in claim 2, wherein the predefined wireless network identifier is a Service Set Identifier.

4. A method as claimed in claim 1, wherein the wireless transceivers are Bluetooth transceivers.
