  • Patent number: 8880683
    Abstract: 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.

  • Patent number: 8774211
    Abstract: A mobile terminal receives a class identifier and receives a broadcast message with a backoff period definition for multiple classes of mobile terminals. The mobile terminal applies the class identifier to the backoff period definition to determine a backoff interval for the mobile terminal. The mobile terminal sends, to a base station, a radio resource control (RRC) connection request using the calculated backoff interval. Different backoff intervals are assigned to different classes of mobile terminals to control network access congestion at the base station.

  • Patent number: 8705490
    Abstract: 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.

  • Publication number: 20130301540
    Abstract: 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.

  • Publication number: 20130245939
    Abstract: A first navigation device records first direction information as the first navigation device traverses a route from a first location to a second location, and transmits the first direction information to a second navigation device while the second navigation device is following the first navigation along the route. After recording the first direction information and while transmitting the first direction information, the first navigation device records second direction information as the first navigation device traverses the route from the second location to a third location. The first navigation device transmits the second direction information to the second navigation device. The first direction information and the second direction information include information that allows the second navigation device to follow the route traversed by the first navigation device.

  • Publication number: 20130246564
    Abstract: A device receives, from a user device and via a first device, a first request for content, and determines whether the content is stored in memory. The device identifies first other requests for the content, received via the first device over a time period, and second other requests for the content, received via a second device over the time period, when the content is stored in the memory. The device identifies a first quantity of the first other requests and a second quantity of the second other requests, and determines whether the first quantity or the second quantity is greater than a threshold. The device transmits the content, to the user device and via the first device, when the first quantity is not greater than the threshold, and transmits, to the second device, an instruction to store the content when the second quantity is greater than the threshold.

  • Patent number: 8472950
    Abstract: 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.

  • Patent number: 8442556
    Abstract: A device sends, to a mobile device, instructions to collect location-based data associated with calls conducted by the mobile device over a wireless access network and receives, from the mobile device, the location-based data, where the location-based data includes a three-dimensional location and a time associated with each of multiple calls conducted by the mobile device over the wireless access network. The device combines the location-based data with other location-based data from other mobile devices and identifies, based on the combined location-based data and other location-based data, a localized area of congestion for the wireless access network.
