  • Patent number: 7190682
    Abstract: Radio heads, methods and systems are provided for communicating data in a radio communications system. The data communications system includes first and second radio heads. The first radio head has at least first and second transceivers. The first radio head includes a first control processor coupled with each of the at least first and second transceivers wherein the first control processor receives a first plurality of timeslots including at least one control timeslot. The first control processor reads control information from the at least one control timeslot of the first plurality of timeslots and provides the control information from the at least one control timeslot of the first plurality of timeslots to each of the first and second transceivers. Finally, the first control processor generates a second plurality of timeslots. The second radio head includes at least third and fourth transceivers.

  • Patent number: 7181242
    Abstract: Carrier data can be communicated between a carrier interface of the first radio base station node and a mobile switching center over a carrier bus according to a carrier protocol. In addition, bus data can be communicated between a bus interface of the first radio base station node and a second radio base station node over a radio base station bus according to a radio base station protocol that is different from the carrier protocol. Related radio communications systems and nodes are also discussed.

  • Patent number: 7068976
    Abstract: A base station tunes a transceiver to listen to accesses made by mobile terminals on the base station's own control channel. Once the functionality of the transceiver is verified by correlating the known accesses to the received accesses, the base station then tunes the transceiver to control channels of nearby cells to receive accesses directed to those nearby cells. From these accesses, the MSC can determine carrier-to-interference ratios between the cells.

  • Patent number: 7061884
    Abstract: A first frame of carrier data can be communicated between a first carrier interface of a first radio base station node and a mobile switching center over a first carrier bus. In addition, a first frame of bus data can be communicated having a first number of dedicated control timeslots at a first bus interface of the first radio base station node over a first radio base station bus. Furthermore, a second frame of carrier data can be communicated between a second carrier interface of a second radio base station node and the mobile switching center over a second carrier bus. Finally, a second frame of bus data having a second number of dedicated control timeslots, different from the first number of dedicated control timeslots, can be communicated at a second bus interface of the second radio base station node over a second radio base station bus.

In addition, a first frame of bus data can be communicated having a first number of dedicated control timeslots at a first bus interface of the first radio base station node over a first radio base station bus. Furthermore, a second frame of carrier data can be communicated between a second carrier interface of a second radio base station node and the mobile switching center over a second carrier bus. Finally, a second frame of bus data having a second number of dedicated control timeslots, different from the first number of dedicated control timeslots, can be communicated at a second bus interface of the second radio base station node over a second radio base station bus.

  • Publication number: 20020090944
    Abstract: A wireless communication network and related method for communicating with mobile terminals, including a plurality of spaced radio heads each authorized to use all frequencies in a spectrum, a memory and a controller. The memory stores, for each of the radio heads, an identification of which of the other radio heads unacceptably interfere with the each radio head. The controller controls the frequencies used by the plurality of radio heads whereby a frequency being used by one radio head is denied use to radio heads unacceptably interfering with the one radio head, and controls handoff of a mobile terminal communicating with a first radio head on a first frequency to change to communicate with a second radio head. A soft handoff is performed if none of the radio heads stored in the memory as unacceptably interfering with the second radio head are using the first frequency.
