摘要:
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.

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:
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.

In various embodiments, a mobile radio communication device is provided. The mobile radio communication device may include a mobile radio communication protocol circuit configured to provide a home base station function for a mobile radio communication with a mobile radio communication terminal device, and a mobile radio resources allocation and reservation circuit configured to allocate and reserve mobile radio resources to a home base station for mobile radio user data transmission between the mobile radio communication device and the mobile radio communication terminal device.
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.
