AI Technical Summary

Problems solved by technology

This means that, for paging or other purposes, the network can only reach the WTRU through all assigned TAs, which unnecessarily increases the paging load
Furthermore, the criteria and method for assigning multiple TAs to a WTRU is unclear

Embodiment

[0073] CLAIMS 1. A method in a base station for allocating a tracking area (TA), comprising: determining a mobility state of a wireless transmit / receive unit (WTRU); and allocating a TA based on the determined mobility state.

[0074] 2. The method of embodiment 1 wherein the allocating comprises allocating a TA or small TA to the WTRU when the WTRU is in one of a stationary state and a low mobility state.

[0075] 3. The method of embodiment 2, wherein the small TA contains more than one cell.

[0076] 4. The method of embodiment 1, wherein the allocating comprises allocating multiple TAs or large TAs to the WTRU when the WTRU is in a high mobility state.

[0077] 5. The method of embodiment 4, wherein the large TA comprises multiple cells.

[0078] 6. A method, in a wireless transmit / receive unit (WTRU), for determining access to a restricted subscriber group (CSG) cell, comprising: receiving a CSG tracking area (TA) identifier; storing the received CSG TA an identifier; r...

Abstract

Provided is a wireless transmitting / receiving unit (WTRU) and an Implementing method in WTRU. The method includes: determining a measured cell reselection time; setting a motion based on the measured cell reselection time, wherein setting the motion as a low-speed motion when the measured cell reselection time is less than a first threshold, setting the motion as a middle-speed motion when the measured cell reselection time is larger than the first threshold but less than a second threshold, and setting the motion as a high-speed motion when the measured cell reselection time is larger than the a second threshold.

Description

[0001] This application is a divisional application of a Chinese invention patent application with an application date of March 7, 2008, an application number of 200880007441.7, and an invention title of "Balancing Paging Load and Allocation Tracking Area Update". technical field [0002] The present invention relates to wireless communications. Background technique [0003] The 3rd Generation Partnership Project (3GPP) recently launched the Long Term Evolution (LTE) project to provide new technologies, new network structures, new configurations, and new applications and services to wireless cellular networks to provide improved spectral efficiency and faster user experience. [0004] In LTE, the Tracking Area (TA) concept replaces the Universal Mobile Telecommunications System (UMTS) Routing Area / Location Area (RA / LA) and UMTS Terrestrial Radio Access Network Registration Area (URA) concepts to simplify mobile area tracking operations And reduce the load caused by the area...
