摘要:
Wireless communication devices may directly communicate within groups of wireless communication devices using Layer-2 communications to implement “push-to-talk” type applications. In one implementation, a method may include generating a floor request signaling message to take control of a communication channel for a group. After transmitting data relating to the communications, a floor release signaling message may be generated and transmitted a number of times.

Methods and apparatus that enable and optimize the simultaneous operation of several wireless femtocells having overlapping coverage areas. In one embodiment of the invention, a resource allocation (e.g., time-frequency grid for an OFDM or TDMA based wireless network) governs the simultaneous operation of several femtocells with overlapping coverage areas by specifying uses for resources. A resource allocation unit (RAU) entity is disclosed for managing and modifying resource allocations for femtocells. The community of femtocells can flexibly share resources according to the time-frequency grid, thereby maximizing spectral efficiency without requiring substantial network overhead.
摘要:
Communications system having first, second, and third communications networks, a subscriber device, and a network access device having a network layer address. The network access device permits access by the first communications network to the third communications network and access by the second communications network to the third communications network. There is a communications link between the subscriber device and the third communications network via the first communications network and the network access device, wherein the network layer address is used during the transmission of data via the first communications link. The network access device has a control device that releases the first communications link and sets up a second communications link between the subscriber device and the third communications network via the second communications network and the network access device. The network layer address of the network access device is used during the transmission of data via the second communications link.

In an embodiment, a mobile radio communication device is provided. The mobile radio communication device may include a mobile radio communication protocol circuit configured to provide a mobile radio base station function for a mobile radio communication with another mobile radio communication device, a network control interface circuit configured to receive communication control signals from a mobile radio network circuit being controlled by a mobile radio network operator to control the mobile radio communication protocol circuit, and a trusted processing circuit configured to process a computer program in a trusted processing environment to provide a trusted processing result, wherein the trusted processing circuit is outside of the mobile radio network operator's domain.
摘要:
Methods and apparatus for providing proof of multiple entities being co-located at a specific time and location. An attestor transmits an attestation message via short range communication; the attestation message includes a time stamp, a location stamp, and a verifiable digital signature. An attestee that stores the attestation message can produce the attestation message at a later time to any interested party, as proof of co-location with the attestor at the specified time and location. In one exemplary embodiment, the methods and apparatus are substantially “open” for public implementation. Such public implementation enables attestors and attestees without prior affiliation, to provide attestation. Furthermore, the device-agnostic methods and apparatus can provide attestation capabilities even in previously deployed systems and devices.
摘要:
Methods and apparatus that reduce network management overhead required for the operation of wireless femtocells. In one aspect of the invention, a central network entity governs the simultaneous operation of several femtocells by specifying modes of operation, and operational parameters for one or more of the femtocells. In one embodiment, at least one of the specified modes of operation directs a femtocell to operate in a substantially autonomous manner within the network-defined operational parameters. The network-defined constraints are provided to the femtocell for example, responsive to a successful registration attempt.
摘要:
Methods and apparatus that provide user access control within wireless networks such as those having both fixed and portable nodes. In one embodiment, the network comprises a 3G cellular network or Interworking WLAN (iWLAN), and the portable nodes comprise Home Node B (HNB) base stations. The HNB is configured to authenticate new users, and provide network access while still maintaining user privacy. The portable nodes also may operate in a number of different operating modes which provide different functional control over user access. In one variant, an easy-to-use owner-assigned ID based access control mechanism with a reliable unambiguous user ID is utilized. Methods for providing access control across differing network architectures and protocols, such the aforementioned iWLAN, and business methods, are also described.

A method of accessing a physical random access channel, a method of signaling access information for accessing a physical random access channel, a mobile communication terminal and a base station are provided. The method of accessing a physical random access channel comprises selecting a plurality of transmission time intervals from transmission time intervals being allowed for accessing a physical random access channel, randomly selecting one transmission time interval of the plurality of transmission time intervals, and accessing the physical random access channel in the randomly selected transmission time interval. A mobile communication terminal is configured to carry out the method.
