Abstract: The present invention is a system and method for wireless emergency notification. In embodiments, a Civic Notification Service Centre (CNSC) generates a notification message, the notification message including a location identifier and notification information. The location identifier represents a geographical area such as a postal code, city street, neighborhood, or municipality. The CNSC transmits the notification message to a message switch that translates the location identifier to at least one device identifier such as a CAP code that is allocated to a set of notification devices assigned to the geographical location defined by the location identifier. Alternatively, the device identifier could be directly input within the notification message. After translation, the resulting notification message is transmitted to a set of base stations which subsequently transmit the notification message to a plurality of notification devices.

Abstract: A method, apparatus and system for dynamically routing selected calls through an intelligent switched telephone network are described. The method leverages the resident switching power in the Public Switched Telephone Network by departing from the Advanced Intelligent Network (AIN) call model while adhering to the basic principles of ISUP common channel signaling to introduce new flexibility in call routing. Using the method, calls can be efficiently routed and rerouted through the network. Control of a call can be effected by either the called party or the calling party. The method can be practised using either a virtual switching point (VSP) or an ISTP. The VSP is a physical mode in the signaling plane of the network and a virtual node in the switching plane. Calls are routed to the VSP using dedicated trunk groups which may be loop-back ISUP trunks or inter-switch ISUP trunks. Calls are routed to the dedicated trunk groups using standard routing translation tables and methods.

Abstract: In a telephone network having a number of telephone switching offices which have CCS7 signalling capabilities and wherein each switching office is linked to STPs (Signalling Transfer Points), or other switching offices with CCS7 signalling links, a method of detecting mass calling events using CCS7 signalling data is disclosed. Each signalling link connecting a switch is monitored. For each call, an Initial Address Message sent from an originating switch to a terminating switch is identified. The IAM is then temporarily stored in storage means. When the occurrence of a release message indicative of an unsuccessful call attempt is detected, an identification of which of the stored IAMs corresponds to the release message is made. A count is computed for each directory (DN) having an IAM with a corresponding release message indicative of an unsuccessful call attempt such that mass calling events directed to a directory number can be detected.
