Abstract: A system and method for providing information local to a called party located in a different geographic location may include storing information and telephone number identifiers as associated with remote geographic locations. In response to a telephone number being dialed, a determination may be made as to whether a portion of the dialed telephone number matches a stored telephone number identifier. If a portion of the dialed telephone number matches a stored telephone number identifier, at least a portion of the information associated with the matched telephone number identifier may be presented to a user. Otherwise, information associated with a portion of the dialed telephone number that identifies a geographic location from a communications network may be requested and presented to the user.

Abstract: A system and method for distributing remote location information to callers who place calls to the remote locations may include storing information at a central computing system. The information may be associated with locations in multiple different time zones and include telephone number identifiers and local times associated with the different respective telephone number identifiers. The information may be distributed to communications network nodes in different time zones. Telephone calls may be processed from callers local to the communications network nodes. In response to receiving a call request at a communications network node from a local caller, a determination by the communications network node using a portion of a called telephone number may be made to determine current time local to the called telephone. The current time local may be communicated to the caller prior to connecting the call with a communications device associated with the called telephone number.

Abstract: A system and method for assisting with calls to public safety answering points may include receiving emergency message data from a user, and, in response to receiving an emergency call request from the user at a telecommunications device, communicating the emergency message data in an audio format to a PSAP.

Abstract: A system and method for registering the contact information of mobile devices with a service 911 service is presented. In one embodiment, a mobile switching center receives the contact information of a mobile device. If the mobile switching center determines that the mobile device is not located within a particular wireless sub-network, such as, but not limited to, a wireless sub-network associated with an area code registered to the mobile device, the mobile switching center generates a reverse 911 registration text message and transmits the reverse 911 registration text message to the mobile device. A user of the mobile device may then transmit the reverse 911 registration text message to a local reverse 911 database to have the contact information associated with the mobile device added to the local reverse 911 database.

Abstract: In one embodiment, when a mobile device is powered on, a mobile switching center acquires the contact information, such as, but not limited to, a phone number and the physical location associated with the mobile device. If the mobile device is a new device to the area, the contact information of the mobile device is passed to a reverse 911 database in order for a user of the mobile device to receive local alert messages transmitted by a reverse 911 system.

A determination of distribution of previous emergency data messages to the identified PSAPs may be performed. Based on the distribution of previous emergency data messages to the identified PSAPs, one of the identified PSAPs may be selected and the emergency data message may be routed thereto.

Abstract: A system and method for routing an emergency data message to a PSAP may include receiving an emergency data message and cell code identifier indicative of a location of a wireless communications device of a user. A PSAP local to the user may be selected, and the emergency data message is sent to the selected PSAP. The location may be a centralized network location associated with an emergency network address, where the emergency network address is an easy address for users to remember.

Abstract: A system and method for generating one-way speech signal samples may include, in a telecommunications network, establishing a call connection between a far-end telephone and a near-end telephone. A resistance component may be selectively configured in parallel with the far-end telephone, where the resistance component has a value representative of resistance produced by the far-end telephone being off hook. A speech signal being communicated from the near-end telephone may be recorded.

Abstract: A system and method for establishing a signal parameter threshold for switching between communications protocols by a multimode handset may include providing cordless telephones of different models. A dropout point at which a communications signal of each of the cordless telephones deteriorates below a predetermined level may be determined. At least one signal parameter of the communications signal at the determined dropout point of each of the cordless telephones may be measured and collected. The signal parameter(s) associated with the cordless telephone having the shortest range at which the associated dropout point may be determined so that a multimode handset may be established with the signal parameter(s) to cause the multimode handset to switch communications protocols in response to the multimode handset crossing a signal parameter threshold level defined by the predetermined signal parameter(s) when communicating with a base unit of a cordless telephone.

Abstract: A phone, method, and system are presented for determining whether a cordless handset is positioned on a base unit of a cordless telephone. An on-base unit signal may be generated in response to a cordless handset being positioned in contact with a base unit of a cordless telephone and an off-base unit signal may be generated in response to the cordless handset not being positioned in contact with the base unit. The on-base unit signal or the off-base unit signal, depending upon the position of the cordless handset, maybe communicated over a communications network with which the base unit is in communication.

Abstract: A system and method for providing location information to a public safety answering point from a softphone may include receiving, at a network access point, an emergency 911 call from the softphone. The emergency 911 call may be communicated to a public safety answering point. In response to a call connection message being received, an address location of the network access point to which the softphone is in communication in placing the emergency 911 call to the public safety answering point may be communicated in a type II caller ID data packet. The softphone may generate the type II caller ID data packet with the address location in a data field, such as a data field typically used for name information of a caller.
