  • Publication number: 20190254083
    Abstract: Methods for selecting network slice, session management, and user plane functions for for user equipment (UE) are described. In one example, a control plane (CP) entity for mobility management may select a CP entity for session management for a session of a UE based on a first set of data items. The CP entity for mobility management may further select a user plane (UP) entity for the session of the UE based on a second set of data items, where second set of data items include at least some of the same data items of the first set. The CP entity for mobility management may send, to the selected CP entity, a message including an identity or indication of the selected UP entity for the session of the UE. The selected CP entity may select the identified or indicated UP entity for use in the session of the UE.

  • Patent number: 9357524
    Abstract: This disclosure relates to systems and methods for paging devices in a communication network. A network device providing mobility management through control messaging can be assigned a number of cell sites in multiple tracking areas. The network device such as a mobility management entity (MME) can use a subscriber-aware implementation to provide a hierarchy for contacting a mobile device with a page. The subscriber-aware implementation can be tailored to analyze subscriber activity such as frequency and timing, to page a subset of the total number of cell sites in multiple tracking areas based on the subscriber activity, and to expand the subset after unsuccessful attempts to page the mobile device.

  • Patent number: 9270709
    Abstract: A method is provided in one example and includes receiving a request from a first network element associated with a first network for establishing a first communication session between the first network element to a first user device associated with a second network. The request includes a first user identifier used to identify a first user associated with the first user device within the first network. The method further includes translating the first user identifier to a second user identifier in which the second user identifier is used to identify the first user within the second network. The method still further includes sending a first query including the second user identifier to a second network element, and receiving a first response message including quality of service information indicated by a policy associated with the second user identifier.

  • Publication number: 20150289167
    Abstract: A method is provided in one example and includes receiving at least one first input indicating at least one network condition associated with a first user device having a user associated therewith. The first user device has a first bearer channel established between the first user device and a gateway, and the first bearer channel has a first quality of service level. The method further includes determining whether to modify the first user device to a second quality of service level based upon the received at least one first input, and sending a first request to a first network element instructing the first network element to modify the first user device to the second quality of service level.

  • Publication number: 20150278296
    Abstract: A method is provided in one example and includes receiving data from a mobile network entity, parsing the data to determine a first identity and first attribute information associated with the first identity, determining whether the first identity exists in a database, storing the first identity in the database if the first identity does not exist in the database, and storing the first attribute information in association with the first identity in the database. The method further includes determining whether there is at least one identity related to the first identity in the database, and updating each of the related identities with the first attribute information when it is determined that there is at least one identity.

  • Patent number: 8924574
    Abstract: In a system and method for establishing communications in a communications network, a network service provider can assign IP addresses to mobile devices dynamically to conserve IP address resources. A network service provider can also implement network address translation to further conserve IP address resources and to provide improved security. If a requestor seeks to obtain an IP address of a mobile device and the address is a local address, the system determines if the mobile device has a network address translation (NAT) binding that associates the IP address of the mobile device with a public IP address. If the mobile device does not have a NAT binding, the system creates a NAT binding that associates the IP address of the mobile device with a public IP address.

  • Patent number: 8769626
    Abstract: Techniques are provided for performing web authentication of mobile wireless devices that roam from a wireless wide area network to a wireless local area network. A redirect rule is invoked when a request is received from the mobile wireless device for world wide web access in order to obtain authentication for the mobile wireless device before permitting world wide web access. When a world wide web access request is received from the mobile wireless device, it is redirected to an authentication portal to allow a user of the mobile wireless device to enter user credentials to allow for world wide web access using the IP address.
