In some implementations, a network device (e.g., an Internet protocol multimedia subsystem (IMS) application server (IMS-AS) may receive, via a first communication interface, from a call session control function (CSCF) device, a request to register for an Internet protocol multimedia subsystem (IMS) service. The network device may provide via a second communication interface between the network device and a unified data management (UDM) device, and to the UDM device, a request for IMS service information associated with the IMS service. The network device may receive based on providing the request for IMS service information, via the second communication interface, and from the UDM device, IMS service information. The network device may cause, based on the IMS service information, the IMS service to be provided to a user device associated with the request to register for the IMS service.

Systems and methods for facilitating provisioning of internet protocol multimedia subsystem services

A method, a device, and a non-transitory storage medium provide an emergency call support service in which a network device of a visited network obtains user profile data of a wireless device from a home network of the wireless device, and provides the user profile data to a location server of the visited network. The emergency call support service allows an emergency call, when initiated by a roaming subscriber of the wireless device via the visited network, to include the user profile data and be provided to a public safety access point.

A system may receive a registration request that identifies a first user device identifier. The system may determine that the first user device identifier is not registered. The system may transmit an authentication challenge. The authentication challenge may request one or more credentials associated with a subscriber profile. The first user device identifier may be associated with the subscriber profile. The system may cause the first user device identifier to be registered based on a challenge response. The first user device identifier may be registered based on a result of authenticating the registration request. The system may receive subscriber information that is associated with the first user device identifier, based on causing the first user device identifier to be registered. The system may determine that the subscriber information identifies a second user device that may be associated with the subscriber profile. The system may provide a notification.

Detecting a second user device identifier based on registration of a first user device identifier

A device may receive a first call associated with a virtual phone number associated with a first user device and a second user device. The device may determine, and may store information indicating, that the first call was made using the first user device. The device may receive a second call directed to the virtual phone number and may determine whether the second call comprises a call back associated with the first call. The device may selectively send the second call to the first user device or to the first and second user devices based on determining whether the second call comprises the call back. The second call may be sent to the first and second user devices when the second call does not comprise the call back and may be sent to the first user device when the second call comprises the call back.

Calling back a device that made a call

A request to access a location-based service is received via a wireless access point (WAP). A WAP identifier associated with the WAP may be identified based on the request and a particular geographic location associated with the WAP may be determined based on the identifier. For example, a WAP information service (WIS) may store data associating geographic locations and WAP identifiers corresponding to a plurality of WAPs that include the WAP, and the particular geographic location may be determined by querying the WIS, based on the particular WAP identifier, to identify the particular geographic location. A communication may be established between the user device and location-based service based on the particular geographic location associated with the WAP.

Location-based telephone calls over a wireless local area network (WLAN)

One or more devices may receive information that identifies a format of an identifier of a network device. The format of the identifier may indicate a portion of the identifier that identifies a type of the network device. The one or more devices may receive the identifier of the network device based on a user device connecting with the network device to communicate via the network device; determine the type of the network device connected to the user device based on the portion of the identifier and a format of the identifier that identifies the type of network device; and execute a processing instruction based on the type of network device connected to the user device.

Identifying base station types

One or more devices may receive an instruction to generate an index for a customer associated with a base station and may generate the index based on receiving the instruction. The index may include one or more spaces to store a corresponding one or more access identifiers (IDs) used to allow a user device to connect to the base station. The one or more devices may receive an instruction to add an access ID to the index; generate the access ID based on a format of the access ID, a customer type, a customer ID, or a space ID; store the access ID in one of the one or more spaces of the index; and provide the access ID to the user device and the base station. The access ID may permit the user device to connect to the base station to access a network via the base station.

Network device access ID assignment and management

A method performed by a domain name service client includes storing DNS entries in a local cache; sending a DNS query to another device to obtain an update to one of the DNS entries; determining whether a DNS response is received; and resetting a time-to-live (TTL) timer associated with the one of the DNS entries when the DNS response is not received.

Failure system for domain name system client

The present invention provides a method and apparatus for network access for consumers in both wired and wireless environments. Multiple-interface/multiple-connections are used to support high-speed handoff and seamless roaming between different networks (wired and wireless). The present invention is implemented by using multiple interfaces and connections to interface a mobile PC unit, providing additional functions, and enhancing current PC device drivers and software.

Integration of the cellular network with an IP based network is disclosed. An integrated IP/cellular network can route packetized voice and data together in a more efficient manner. The present invention integrates IP based standards for a cellular IP solution with cellular centric vs. IP message gateway as the demarcation point. However, the present invention also provides support for cellular unique features for better performance. Multiple architectures are proposed to ease migration to a combined network as well as to show the various levels of support provided.

Architecture of internet protocol-based cellular networks

In existing standards for packet data communication over enhanced cellular networks, for a subscriber having a static address, the network relies on the terminal to provide the static address. Consequently, the terminal needs to know (be programmed with) its own static address and typically the address of a home agent element of the network. To eliminate the attendant need to provision such address data in the mobile station, the static address is stored in a node of the network, and the network assigns that one address to the mobile station, every time when the subscriber requests packet data service, for example, using a mobile IP (MIP) type address assignment procedure. The address assignment operation may also provide the home agent address to the station.

Network based IP address assignment for static IP subscriber

Improved billing accuracy in session-based communications is provided by separating session (or connection) billing from session processing. If two sessions () on the same serving node are bridged, so the true stop time of the prior session () is not known, the stop time of the prior session is defined as a function of the last activity during (TALS) that session. To accomplish this, the serving node detects and stores the time of last activity and the time of initiation for each connection and determines the billing time accordingly, regardless of the state of the inactivity timer () or whether sessions were bridged by the serving node.
