Abstract: Systems and methods for classifying and routing an inbound call using ENUM queries are described. When a calling party initiates an inbound call, an Interconnect Session Border Controller (I-SBC) may generates a query for a calling party number (CgPN) and a called party number (CdPN) to search the inbound call in an E.164 Number to URI Mapping (ENUM) database. The I-SBC may check the CgPN against the ENUM database and identify a service provider identification (SPID) number associated with the classification of the CgPN found in the ENUM database. The I-SBC may then tag the SPID and an associated predetermined description to the inbound call, and route the inbound call based on the SPID.

Abstract: When authorized, a user of a computing device, such as a smart phone, may select an originating phone number to initiate a voice call that is different from the telephone number that is assigned to the computing device. The telephone number that is selected as the originating number may be a number that is assigned to another computing device and/or a different user. In response to receiving a request to place an outgoing call using the selected destination number, the network returns a temporary routing number to the computing device. The computing device places a call to the temporary routing number. After receiving the call at the temporary routing number, the network places the outgoing call using the selected originating number. The outgoing call appears to a called party to originate from the selected originating number instead of from the phone number assigned to the computing device.

Abstract: In some implementations, a core network device can receive an initiation request of a communication session to an alias number. The core network device can retrieve from a registration database one or more destination number(s) corresponding to the alias number. The core network device can transmit respective indication(s) of the alias number to destination(s) corresponding to the retrieved destination number(s). The core network device can initiate the communication session to one of the destination(s) using the respective one of the retrieved destination number(s). A destination number can correspond to a computing device, e.g.

Abstract: In some implementations, a computing device may determine a location of the computing device. The computing device may have an associated first phone number. The computing device may determine that the location of the computing device is outside a geographic area in which a carrier associated with the first phone number provides service. The computing device may send a registration request to a local network indicating that the computing device is operating in an over the top mode. The computing device may originate an outgoing call from the computing device. The outgoing call appears to a called party to originate from a second phone number that is different from the first phone number.

Abstract: In some implementations, a telecommunications network can include a core network device communicatively connectable with user equipment (UE). The UE can generate a registration request including a subsidiary request and transmit the registration request. The core network device can receive the registration request, determine the subsidiary request based on content of the registration request, and transmit an indication of the subsidiary request on behalf of the UE via the telecommunications network. A core network device can receive a registration request associated with a user equipment (UE), determine a subsidiary request based on content of the registration request, and transmit toward the UE an acknowledgement associated with both the registration request and the subsidiary request.

Abstract: When authorized, a user of a computing device, such as a smart phone, may place a communication using an originating number that is different from the number assigned to the computing device. An IMS application server that handles requests for the computing device associated with the originating number is notified when the telephone number assigned to the computing device is used by a different computing device. The notification to the IMS application server might include, but is not limited to device information, location information, and the like. After being notified of the communications terminated by other computing devices that are associated with the device number, accurate call records may be provided regarding the communications involving the originating number.

Abstract: When authorized, a user of a computing device, such as a smart phone, may associate a telephone number that is assigned to a computing device with other computing devices. The other computing devices may or may not have an assigned device number. A user may also select to use the same number as the originating number of an electronic device. For example, a user may specify that each computing device associated with the user utilizes the same telephone number. The user may also specify that a computing device not utilize an assigned number. The associations of a device number with the computing devices may be stored as implicit registration data and/or as hunt groups.

Abstract: This disclosure is directed at least partly to routing calls and/or other communications from a Mobile Virtual Network Operator (MVNO) that uses a Mobile Network Operator (MNO) as a transit network. The MVNOs may desire to use the MNO's network as a transit network to complete or terminate calls from users who may be roaming and/or are on other access networks such as Wi-Fi. The MNO may implement logic to determine whether to allow the MNO's network to be used as a transit network based at least in part on conditions such as one or more of agreements with an MVNO, business considerations, and/or other considerations (e.g., network bandwidth, etc.). The logic may enforce the rules by selectively allowing some communications and denying other communications.

Abstract: Methods and computing systems for dynamic MSISDN association are described. A network device receives a location update message from a mobile network switch. The location update message indicates that a mobile device is registered with the mobile network switch. The location update message includes an international mobile subscriber identity (IMSI) associated with the mobile device. The network device determines, based at least on the IMSI, a plurality of MSISDNs associated with the mobile device, including a first MSISDN that is enabled for calling and a second MSISDN that is not enabled for calling. The network device transmits, in response to the location update message, subscriber data to a database associated with the mobile network switch, which associates the IMSI with the first MSISDN.

Abstract: Devices configured to initiate a handover of a communication session of a user device from an access network associated with unlicensed spectrum to a circuit-switched access network are described herein. The devices may provide a handover request to a server associated with the circuit-switched network, receive a response from the server indicating that the circuit-switched access network has been prepared for the handover, and instruct the user device connect to the circuit-switched access network to continue the communication session. The devices may initiate the handover responsive to measurement reports received from the user device.
