Abstract: Before call handover between radio network subsystems (RNS's) of a radio access network, a serving radio network controller (RNC) of a first RNS determines the level of congestion in an Iur interface between the serving RNC and an RNC of a second RNS. If the Iur interface is determined to be congested when a call handover is required, the serving RNC uses the Iu interface with a core network of the radio access network to signal the core network to perform a call handover, and the core network uses the Iu interface with the RNC of the second RNS to signal the RNC of the second RNS to become a serving RNC for the call.

Abstract: A folding billiard table is provided with a pair of supports having legs and wheels thereon respectively for stability and easy handling purposes when the table is in correspondingly normal unfolded and folded configuration. A table formed of two symmetrical parts incorporating a center assembly thereunder to facilitate folding operation through a pair of gear racks. The center assembly is pivotally fixed to the underside of the two parts respectively at one end while the other end portion is further engaged with a pair of gears held in a fixed configuration in relation to said center assembly. A plurality of linking and reinforcing bars are provided to make the table a rigid assembly, and facilitate, the changing from normal unfolded to folded configuration or in reverse which is also effected by the operation of a spring, a tension block, and a locking mechanism disposed thereunder. Moreover, the space occupied by the table when in the folded configuration is obviously minimized.

Abstract: A folding tennis table having a pair of planar surfaces, each being one half of the table playing surface. The halves are hingedly connected at adjacent edges by support structure. The support structure is comprised of four brackets, two brackets being placed on the lower surface of each table half. A brace is retained between a pair of brackets, one bracket being on each surface. An extension bar is pivotably attached to each brace and a leg frame. The leg frame is hollow and has a leg telescopically extending therethrough. The leg is provided with a swivel bar so as to be pivotably attached to allow the table to be folded in one step.
