    摘要： A device receives, from multiple network elements, status information for a user equipment (UE) connection associated with a wireless core network and updates, based on the status information received from the network elements, a database record for the UE connection. The device receives, from an application server, a request for information associated with the UE connection and constructs, based on the request and from the database record, a resource message that includes real-time information about the UE connection. The device sends the resource message to the application server. The device also provides a disconnect message to the application server and/or the network elements when the status information received from the network elements indicates that the UE has been disconnected from the wireless core network.

    摘要： A 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 session initiation protocol (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 an attachment request from a user device, and determines whether the user device is a stationary device based on the attachment request. The device further establishes a connection between the user device and a network by using local components associated with the device when the user device is the stationary device. The local components perform functions performed by one or more of a remote mobility management entity (MME) device, a remote serving gateway (SGW), or a remote packet data network (PDN) gateway (PGW) associated with the device. The device also transmits data from the network to the user device via the local components associated with the device after establishing the connection between the user device and the network.

    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.
