Automatic building of neighbor lists in mobile system

In a radio access network (24) a femto radio base station (28f) comprises a resident receiver (54) which acquires system information broadcast in a radio access network (24). At least part of the system information is used for building, at the femto radio base station (28f), a neighbor data structure (59) comprising information for neighboring cells. The neighbor data structure (59) is then used for building a neighbor list. The neighbor list is subsequently transmitted from the femto radio base station (28f) to a user equipment unit (30) served by the femto radio base station (28f). In some example embodiments and modes, the femto radio base station (28f) reports the neighbor data structure to a network node (26, 100) other than the femto radio base station. The other node (26, 100) uses the neighbor data structure for building the neighbor list at the other node. In some example embodiments and modes, acquisition of the system information comprises scanning a surrounding macro coverage area of the femto radio base station for obtaining cell identity information for detected cells. In other example embodiments and modes, the acquisition of the system information can additionally comprise camping on a macro cell and using/consulting at least one system information block in the camped-on macro cell is consulted/used for obtaining information about at least one neighboring cell.

Transmission control protocol/internet protocol (TCP/IP) packet-centric wireless point to multi-point (PTMP) transmission system architecture

A packet-centric wireless point to multi-point telecommunications system includes: a wireless base station communicating via a packet-centric protocol to a first data network; one or more host workstations communicating via the packet-centric protocol to the first data network; one or more subscriber customer premise equipment (CPE) stations coupled with the wireless base station over a shared bandwidth via the packet-centric protocol over a wireless medium; and one or more subscriber workstations coupled via the packet-centric protocol to each of the subscriber CPE stations over a second network. The packet-centric protocol can be transmission control protocol/internet protocol (TCP/IP). The packet-centric protocol can be a user datagram protocol/internet protocol (UDP/IP). The system can include a resource allocation means for allocating shared bandwidth among the subscriber CPE stations. The resource allocation is performed to optimize end-user quality of service (QoS). The wireless communication medium can include at least one of: a radio frequency (RF) communications medium; a cable communications medium; and a satellite communications medium. The wireless communication medium can further include a telecommunications access method including at least one of: a time division multiple access (TDMA) access method; a time division multiple access/time division duplex (TDMA/TDD) access method; a code division multiple access (CDMA) access method; and a frequency division multiple access (FDMA) access method.
The first data network includes at least one of: a wireline network; a wireless network; a local area network (LAN); and a wide area network (WAN). The second network includes at least one of: a wireline network; a wireless network; a local area network (LAN); and a wide area network (WAN).

Method for radio resource control

In order to control the use of physical radio resources, the physical radio resources are divided into chronologically consecutive frames (14), so that a frame contains slots (16, 17, 18) of various sizes, which slots represent a given share of the physical radio resources contained in the frame and can be individually allocated to different radio connections. The first dimension of a frame is time and the second dimension can be time, frequency or code. In the direction of the second dimension the slots represent various sizes, and a given first integral number of slots of the first size can be modularly replaced by another integral number of slots of another size. A certain number of consecutive frames form a superframe (19), in which case frames with corresponding locations in consecutive superframes are equal in slot division and allocations, if the data transmission demands do not change. Changes in the state of occupancy of the slots are possible at each superframe. In order to form an uplink connection, the mobile station sends a capacity request, where it indicates the type of requested connection and the demand of resources. In order to form a downlink connection, the base station subsystem sends a paging call, where it indicates the location in the superframe of the slots allocated to the connection. In order to indicate the state of occupancy, the base station subsystem maintains a superframe-size parametrized reservation table.
