摘要： A network device may store information identifying a coverage area associated with each of one or more cells that are associated with the network device. The network device may receive information identifying a geographic location of a user device. The network device may compare the geographic location of the user device to one or more of the stored coverage areas. The network device may also determine, based on the comparing, that the user device is within a particular coverage area of a particular cell, of the one or more cells. The network device may further send, to the user device, and based on determining that the user device is located within the particular coverage area of the particular cell, an instruction for the user device to connect to the particular cell, where the user device is to attempt to connect to the particular cell in response to the instruction.

摘要： A server device may identify that a user device is connected to a first radio access network (“RAN”), via a first technology. The server device may identify that the user device is capable of accessing a second RAN, via a second technology, where the second RAN is different from the first RAN, and where the second technology is different from the first technology. The server device may also receive an indication that the first RAN is congested. The server device may further determine, based on the indication that first RAN is congested, and further based on identifying that the user device is capable of accessing the second RAN via the second technology, that the user device should be handed over to the second RAN. Additionally, the server device may instruct the user device to connect to the second RAN via the second technology.

摘要： A method and a system provide integrated lawful intercept, for IMS over an Evolved Packet Core (EPC), for both packet data and session initiation protocol (SIP)-based applications. The system includes a device that receives a lawful intercept request from a law enforcement agency, and determines whether a packet data lawful intercept or a SIP-based applications (SBA) lawful intercept is requested by the lawful intercept request. The device also provisions, when a packet data lawful intercept is requested by the lawful intercept request, a policy control and charging rules function (PCRF) and a packet data network (PDN) gateway (PGW) for the packet data lawful intercept. The device further provisions, when a SBA lawful intercept is requested, a proxy call session control function (P-CSCF), a serving-CSCF (S-CSCF), and a session border controller (SBC) for the SBA lawful intercept.

摘要： A device receives a call for a user device associated with an Internet protocol multimedia subsystem (IMS) network, where the call includes a mobile directory number (MDN) associated with the user device, and retrieves, from a home location register (HLR), an address of a wireless intelligent network (WIN) termination trigger service control point (SCP). The device sends, to the WIN termination trigger SCP, a first message that includes the MDN, receives, from the WIN termination trigger SCP, a second message that includes steering digits as a prefix to the MDN, and generates a third message that includes a called party number set to the MDN and omits the steering digits. The device also routes, based on the steering digits, the third message to a media gateway control function/media gateway (MGCF/MGW) of the IMS network, where the MGCF/MGW further processes the call.

摘要： Method and system for a domain name translation service. A plurality of application servers associated with at least one domain name corresponding to at least one Internet Protocol (IP) address are provided. A domain name system (DNS) server hierarchy is configured for providing, based on DNS translation information associated with the requested domain name stored therein, an IP address or a list of IP addresses of the associated application server(s) as a response to a DNS query for a domain name. In addition, a dynamic traffic controller is configured for monitoring the operational status of the application servers and requesting a DNS update to the DNS translation information stored in the DNS server hierarchy based on the operational status of the application servers.

摘要： Emergency call backs may be placed to a user device in a manner that bypasses certain features (e.g., call forwarding) that may be enabled by the device. A method may include receiving an emergency call from a user device; and creating, in response to the emergency call, an emergency session associated with the user device, where the creating includes forwarding the call to a public safety access point (PSAP) server that handles emergency calls. The method may further include receiving a call, such as an emergency call back call, destined for the user device; determining that the emergency session has not expired when an elapse time associated with the emergency session is less than a threshold; and forwarding, to the user device, the call, as a return call from the PSAP server, based on the determination that the emergency session has not expired.
