Abstract

A hierarchical cellular network administration system operative to administrate for a hierarchical cellular network having a core, the hierarchical cellular network administration system comprising a link establishment initiator operative to generate link establishment commands; and relay manager functionality operative to establish at least one link between at least one relay in the hierarchical cellular network and all nodes in said cellular network desired to be served by said at least one relay, as per said link establishment commands generated by the link establishment initiator; and to control operation of links thus established.

Claims

1-80. -80. (canceled)

81. Relay apparatus including:

a relay manager operative to activate at least one link thereby to cause the relay apparatus to function as a node in a hierarchical cellular network; and

a set of radio interfaces operative, when said relay apparatus is disposed at a level n of a hierarchical cellular network having a core, to provide;

a corresponding set of uplinks to said relay apparatus from at least one node disposed at at least one level in said network which is further from the core than level n; and

a corresponding set of downlinks from said relay to said at least one node.

82. Relay apparatus according to claim 81 and also comprising a second set of radio interfaces operative, when said relay is disposed at a level n of a hierarchical cellular network having a core, to provide:

a corresponding second set of uplinks to said relay from at least one node disposed at at least one level in said network which is further from the core than level n; and

a corresponding second set of downlinks from said relay to said at least one node.

87. Relay apparatus according to claim 81 wherein a centralistic manager is operative for computing a backhauling quality grade of each network node, and for then sending the quality grade to at least one client relay apparatus.

88. Relay apparatus according to claim 87 wherein a local routing manager can order handover, if required by an application, according to backhauling quality grades of the Relay apparatus'"'"'s neighbors and radio measurement messages.

83. A data relay manager providing method including:

providing a relay manager, operative to activate at least one link thereby to cause a relay to function as a node in a hierarchical cellular network, and a first set of radio interfaces operative, when said relay apparatus is disposed at a level n of a hierarchical cellular network having a core, to provide;

a corresponding first set of uplinks from said relay apparatus to at least one node disposed at at least one level in said network which is closer to the core than level n, and

a corresponding first set of downlinks from said at least one node to said relay.

84. The method according to claim 83 wherein said set of uplinks and downlinks connect said relay to a single node disposed at a level in said network which is closer to the core than level n.

85. The method according to claim 83 wherein said set of uplinks and downlinks connect said relay to a set of more than one nodes disposed at at least one level in said network which is closer to the core than level n.

86. The method according to claim 85 wherein said sets of uplinks and downlinks connect said relay to a set of nodes corresponding in number to said first set of radio interfaces and disposed at at least one level in said network which is closer to the core than level n.
