Embodiment Construction

[0031]The present system and method provide a system and method for transitioning from RRC connected mode to a more battery-efficient state or mode, while ensuring that the network does not treat the signaling release indication as alarm. In particular, the present method and apparatus provide transitions based on UE initiating signaling connection termination for a specific core network domain, or indicating to the UTRAN that a transition from one connection state to another should occur. The following will be described according to a typical implementation of UMTS. However, it should be appreciated that the teachings of the present invention are similarly applicable to other radio communication systems.

[0032] Specifically, if an application on the UE decides to handle the data exchange, it may send a "done" indication to the "RRC Connection Manager" component of the UE software. The RRC Connection Manager keeps track of all existing applications (including those providi...

Abstract

A method and system for processing signaling release indication cause between user equipment and a wireless network, the method comprising the steps of: monitoring, at the user equipment, whether a signaling connection release indication should be sent to the wireless network; appending, at the user equipment, a cause for the signaling connection release indication to the signaling connection release indication; sending the appended signaling connection release indication to the wireless network; receiving the signaling connection release indication at the wireless network; and filtering saidcause to determine whether to raise an alarm.

Description

technical field [0001] The present application relates to radio resource control between a user equipment (UE) and a universal terrestrial radio access network (UTRAN), in particular the release of existing signaling connections in a UMTS network. Background technique [0002] The Universal Mobile Telecommunications System (UMTS) is a packet-based broadband system used to transmit text, digital voice, video and multimedia. It is highly supportive of third-generation standards and is usually based on Wideband Code Division Multiple Access (W-CDMA). [0003] In a UMTS network, the Radio Resource Control (RRC) part of the protocol stack is responsible for the allocation, configuration and release of radio resources between UE and UTRAN. The RRC protocol is described in detail in the 3GPP TS 25.331 specification. Two basic modes that a UE can be in are defined as "idle mode" and "UTRA connected mode". UTRA stands for UMTS Terrestrial Radio Access. In idle mode, the UE is req...
