Embodiment Construction

[0036] In the following description, for purposes of illustration rather than limitation, specific details are set forth, such as particular structures, interfaces, techniques, etc., in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail. Also, various functional blocks are shown on some drawings.

[0037] The present invention is described in the non-limiting example context of Universal Mobile Telecommunications (UMTS) 10 shown in FIG. 1 . A representative, connection-oriented external core network, shown as cloud 12, may be, for example, the public switched telephone network (PSTN) and / or the integrated services dig...

Abstract

In a cellular telecommunication system, when a User Equipment Unit (UE) [30] seeks to use the FACH common transport channel in a cell controlled by a Drift Radio Network Controller (DRNC) [262], the Drift Radio Network Controller (DRNC) starts with Signaling notifies the Serving Radio Network Controller (SRNC) [261]: whether the Drift Radio Network Controller (DRNC) requires to start the common transport channel resource initialization procedure. If the signaling indicates that the Drift Radio Network Controller (DRNC) does not require to start the common transport channel resource initialization procedure, the serving radio network controller (SRNC) decides whether to start the common transport channel resource initialization procedure relative to the user equipment unit in the cell .

Description

technical field [0001] The present invention relates to wireless telecommunications and, in particular, to the communication between a serving radio network controller (SRNC) and Instructions required for wireless connection of user equipment units, supporting common transport channels. Background technique [0002] In a typical cellular radio system, a mobile user equipment unit (UE) communicates through a radio access network (RAN) to one or more core networks. A user equipment unit (UE) may be a mobile station, such as a mobile telephone ("cellular" telephone) and a laptop computer with a mobile termination, so it may be, for example, a portable , pocket-sized, hand-held, computer-included, or vehicle-mounted mobile devices. [0003] A radio access network (RAN) covers a geographical area that is divided into cell areas, each cell area being served by a base station. A cell is a geographical area where radio coverage is provided by radio base station equipment at a bas...
