Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H01Q 148

US Classification:

343846

Abstract:

An antenna which comprises a plurality of spaced apart antenna segments (1-8) which are electrically isolated from each other and form a conical antenna structure, an insulator (9) disposed between each of the antenna segments, a plurality of conductors (11), each coupled to a different one of the antenna segments, for sampling a predetermined parameter at the associated antenna segment and a ground plane (10) normal to the axis of the conical structure. The antenna segments are substantially pie-shaped. In a second embodiment of the invention, the antenna segments are disposed on an electrically insulating sheet, each of the antenna segments being flared at the corner regions thereof (22) remote from the apex of the conical structure. The space between each of the segments is a slot, the slot operational as a slot antenna when the segments on opposing sides of the slot are excited 180 degrees out of phase.

Abstract:

An access network can allocate a bearer for a network service associated with a quality-of-service (QoS) value (QV) and a retention-priority value (RPV), and determine a bearer ID for the service based on the QV, the RPV, and a supplemental priority value (SPV) different from the QV and from the RPV. Upon handover of a terminal, session(s) carried by a bearer allocated by the terminal can be terminated. That bearer can be selected using IDs of the bearers and a comparison function that, given two bearer IDs, determines which respective bearer should be terminated before the other. Upon handover of a terminal to an access network supporting fewer bearers per terminal than the terminal has allocated, a network node can select a bearer based on respective QVs and RPVs of a set of allocated bearers. The network node can deallocate the selected bearer.
