Abstract: A computer-implemented method of processing an emergency call reported to a Public Safety Answering Point (PSAP) by a user of a first communication device can include an Emergency Service Routing Proxy (ESRP) performing a search operation to track location data of the first communication device in response to receiving an emergency callback request from the PSAP that has received an emergency call from a first communication device. The callback request can be forwarded to a most appropriate gateway of a carrier according to the first communication device's location data. An SIP INVITE request comprising a new header including a request for forking SMS for initiating, at the carrier a procedure for retrieving mobile network addresses of communication devices that are co-located to the first communication device can be sent in response to the callback request not being answered by the first communication device.

Abstract: A method of processing an emergency incident reported to a Public Safety Answering Point (PSAP) by a user of a mobile communication device can include receiving an emergency call, determining the geolocation of the mobile communication device that made the emergency call; triggering an SMS-CB so SMS messages are sent to mobile communication devices located within a predetermined area around the determined geolocation of the device that made the emergency call, and receiving a plurality CB-SMS response messages that include objects related to the emergency incident. An object comparison on objects extracted from the responses can be performed to determine a similarity of the objects with respect to each other. It can also be verified whether the similar objects have been received from co-located mobile communication devices.

Abstract: A method for optimizing an abandoned call notification can be configured to address the misrouting of an emergency call which eventually gets abandoned by the caller, through managing the indication of an abandoned call between various network elements, e.g. Emergency Service Internet Protocol network (ESInet) elements. The abandoned call notification can appear in the correct Public Safety Answering Point (PSAP) without any manual action involved in some embodiments. In addition, embodiments can also address calls which are routed in different jurisdictions due to failures in the original intended routing targets.

Abstract: A method and a system for improving emergency response time for mobile callers can be configured to take advantage of knowledge regarding numerous devices and their states of services they offer. Embodiments of the method and system can be adapted to optimize the selection of one or more alternative destinations for a caller who may be moving while also avoiding unnecessary call re-routings.

Abstract: A method for managing transmission resources in a SIP-based communication system by a SIP registrar server can include receiving a first number of register requests from a first client from the number of clients, each register request corresponding to one slot in the predetermined first time period; receiving a second number of register requests from a second client of the number of clients, each register request corresponding to one slot in the predetermined first time period, wherein the second number of register requests exceeds the acceptable predetermined number of register requests for the second client, and assigning a number of slots not used by the first client within the predetermined first time period to the second client for sending the register requests which exceed the acceptable predetermined number of register requests for the second client. A system for implementation of the method and an apparatus can be utilized in embodiments of the method and the system.

Abstract: A computer apparatus (e.g. a server) and a method for managing transmission resources in a SIP-based communication system can include use of a SIP registrar server that is adapted to receive register requests from a number of clients connected to the SIP registrar server via a communication network. Each client can be granted a predetermined number of register requests in a predetermined first time period where each register request corresponds to a slot. In the first time period, at least one slot not used by a first client can be lent to a second client. In a second time period, the at least one slot lent to the second client can be reclaimed by the first client or another client. The reclaiming of the lent slot(s) can include making the second client function as a proxy for other clients according to a third party registration process.
