  • Publication number: 20140004864
    Abstract: A call request is processed by first determining at a shared transport Call Admission Control (CAC) mechanism an occupancy of each of a plurality of technology-specific CAC mechanisms. If one of the plurality of technology-specific CAC mechanisms is not being utilized, transport bandwidth associated with the one of the plurality of technology-specific CAC mechanisms that is not being utilized is assigned to a second of the plurality of technology-specific CAC mechanisms.

  • Publication number: 20130051379
    Abstract: In a method for controlling access to a local network via a small wireless cell in a wireless network, local network access control information is received at the small wireless cell, and the small wireless cell controls access to the local network by the user based on the local network access control information. The access control information is indicative of whether a user is permitted to access the local network through the small wireless cell, and is independent of wireless network access control information indicative of whether the user is permitted to access the wireless network.

  • Publication number: 20130023301
    Abstract: In one embodiment, the method includes establishing, at a first base station, at least one interface with a second base station. The first and second base stations are associated with different network technologies, and at least one of the first and second base stations is a small cell base station. A small cell base station has a coverage area smaller than and at least partially overlapped by a coverage area of a macro base station. The method further includes one of (i) sending information from the first base station to the second base station over the interface, and (ii) receiving information at the first base station from the second base station over the interface.

  • Publication number: 20110158162
    Abstract: A method is provided for interworking of mobility key management among access networks operating under different access technologies. The method is carried out by performing mobility key management by a core-network authentication server based on the access technology that a mobile terminal accessing a wireless network has selected for operation. The method of the invention defines authentication server behavior based on different access technologies and therefore solves the technology interworking issue seamlessly. The method of the invention also facilitates coexistence of more than two different access technologies without any need for each access technology to be modified in order to interwork with core network that is specified by another technology.

  • Publication number: 20110077021
    Abstract: The present invention provides a method involving a mobile unit, a location server, a location-based application client, and a location-based application server configured to provide location-based applications. The method includes receiving, at the location server and from the location-based application server, a request from location-based application client for a current location of the mobile unit and attempting, at the location server, to determine the current location of the mobile unit. The method also includes providing, from the location server to the location-based application server, information indicating a previous location of the mobile unit when the attempt to determine the current location of the mobile unit is unsuccessful.

  • Patent number: 7646741
    Abstract: A messaging client and associated method for client-based multicast message transmission is provided. In one embodiment, the messaging client includes a message origination process with an input device, message buffer, recipient list, new message area, and multicast message transmission process. In one embodiment, the method includes: a) receiving a message content to be transmitted in a message, b) receiving delivery information for first and second recipients to whom the message is to be transmitted, c) receiving an instruction to begin the message transmission, d) transmitting the message from the client to the first recipient, and e) transmitting the message from the client to the second recipient. The messaging client and associated method relate to short message service (SMS), enhanced message service (EMS), multimedia message service (MMS), and other types of similar message services.

  • Publication number: 20090043901
    Abstract: In one embodiment, a method of the invention has the steps of: (A) establishing an access-layer security association (SA) between a mobile node (MN) and an authentication authorization accounting (AAA) server; (B) deriving a secondary key from an extended master session key (EMSK) corresponding to the access-layer SA; (C) providing the secondary key to a home agent; and (D) based on the secondary key, establishing an SA corresponding to an Open System Interconnection (OSI) layer higher than the access layer for securing communications between the home agent and a selected network node. In various embodiments, the selected network node can be (i) the MN, (ii) a proxy node configured on behalf of the MN, or (iii) a proxy node configured on behalf of the home agent.

  • Patent number: 7242948
    Abstract: In this invention, a wireless terminal location is monitored and used to locate providers of a requested service that are proximate to the location of the wireless terminal. At least one of the providers located is selected and identified by name and/or telephone number and/or the location, etc., and this information is delivered to and stored in the directory of the wireless terminal. The process is repeated as necessary to update the list of service providers when the wireless terminal is transported to a new location area. The service providers located can represent any category of service desired such as emergency facilities (especially in a foreign country) such as paramedics, hospital, police, or roadside assistance, etc.
