A system (100) and method for routing an emergency request message from an Internet user (50) to an emergency-call-answering center (31) consisting of Public Service Access Points (PSAPs). An emergency request message is transmitted to an IP network (60) which is received by an emergency call handling function (172). The emergency call handling function (172) queries a database (170) and returns the physical location information associated with the IP address of the user (50). The call is formatted into a format compatible with the emergency call answering center (31) and transmitted via the PSTN (20) to the PSAP (36) serving the correct emergency service zone for the user (50).

A method and corresponding equipment by which a service access point (SAP) of a radio access network is able to trigger a user equipment (UE) terminal to send scheduling information to the SAP for use by the SAP in scheduling/allocating resources for packet uplink from the UE to the SAP. The method uses an AG (absolute grant) or RG (relative grant) rate control/scheduling message as the trigger. The scheduling information is then sent by the UE via a MAC-e (medium access control-extended) PDU (protocol data unit).

Connectivity fault notification is provided by generating an alarm indication signal at a device that is logically adjacent to the fault, and forwarding the alarm indication signal upward through various levels to at least one client level entity. The alarm indication signal may be suppressed at any level for a service instance if service is restored at that level, or if a protection path prevents disruption of the service instance at that level, or auto-suppressed at an originating node based on number of times transmitted or elapsed time. The alarm indication signal may include a point of failure indicator such as the MAC address of the device that generates the alarm indication signal, or a failed resource identity such as an IEEE 802.1AB LLDP MAC Service Access Point (“MSAP”). Further, the alarm indication signal may be employed to trigger use of the protection path.

The use of the VoIP emergency network for routing wireless E911 calls to a designated PSAP. In this embodiment, a mobile positioning center (MPC) assigns an ESRK per existing prior art, but uses the invention to route the call to the PSAP via the VoIP server and an ESGW. This relieves wireless carriers of the obligation to install and maintain expensive dedicated SS7 or CAMA trunks from each MSC to each selective router in the areas served by that MSC. Instead, wireless 911 calls can be consolidated by ESGW vendors, maximizing the efficiency of the dedicated trunks to the selective router by sharing those trunks with multiple MSCs.
