Selective multi-media broadcast of traffic information
First Claim
Patent Images
1. A method of providing broadcast traffic information in a wireless communication system, the method comprising the steps of:
- determining a normal traffic pattern at a remote network traffic sensing node, the normal traffic pattern comprising an average range of vehicles per unit time during a period of unimpeded traffic flow;
detecting an abnormal traffic pattern at a remote network traffic sensing node, the abnormal traffic pattern comprising a value outside the range of the normal traffic pattern;
when the abnormal traffic pattern is detected, initiating a multimedia session between the remote network traffic sensing node and a broadcast traffic control node; and
transmitting real-time information concerning the abnormal traffic pattern over the multi-media session.

4. A method of providing broadcast traffic information in a wireless communication system, the method comprising the steps of:
-
receiving notification of an abnormal traffic pattern at a broadcast traffic control node;
retrieving a list of mobile stations subscribed to a broadcast traffic information service;
determining the locations of the mobile stations subscribed to the broadcast traffic information service; and
bridging a multimedia session from the remote network traffic sensing node to mobile stations subscribed to the broadcast traffic information service which are a predetermined distance from the remote traffic sensing node to form a bridged session. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)
