    Abstract: The invention performs long term evolution (LTE) tracking area updates (TAUs), and tracking area code (TAC) and public land mobile network identification (PLMN-ID) assisted optimized wireless transmit/receive unit (WTRU) cell reselection. An evolved Node-B broadcasts system information including at least one system information block (SIB) based at least in part on an enhanced universal terrestrial radio access network (E-UTRAN) parameter response message sent by an evolved packet core (EPC) network. A WTRU generates a new TAC, which represents a tracking area identification (TA-ID) of a new cell, based on the system information, and compares the new TAC to an existing TAC, which represents a TA-ID of a previous cell. The WTRU transmits to the EPC network a TAU request message including the TA-ID of the new cell. The EPC network sends either a TAU accept message or a TAU reject message to the WTRU.

    Abstract: A method for assigning a tracking area (TA) is disclosed. A mobility state of a wireless transmit/receive unit (WTRU) is determined and the TA is assigned based on the determined mobility state. Also disclosed is a method for accessing a closed subscriber group (CSG) TA. A CSG TA identifier is received at a WTRU and is stored. A CSG TA broadcast is received and the broadcast CSG TA is accessed if an identifier of the broadcast CSG TA matches the stored CSG TA identifier. Also disclosed is a method for changing a mobility state of a WTRU. A current mobility state of the WTRU is determined and a predetermined metric of the WTRU is examined. The predetermined metric is evaluated to determine if the metric has crossed a threshold and the mobility state is changed based on the evaluated metric.

    Abstract translation: 公开了一种分配跟踪区域（TA）的方法。 确定无线发射/接收单元（WTRU）的移动性状态，并且基于所确定的移动性状态来分配TA。 还公开了一种用于访问封闭用户组（CSG）TA的方法。 在WTRU处接收CSG TA标识符并被存储。 如果广播CSG TA的标识符与存储的CSG TA标识符匹配，则接收到CSG TA广播并且广播CSG TA被访问。 还公开了一种用于改变WTRU的移动性状态的方法。 确定WTRU的当前移动状态并检查WTRU的预定度量。 评估预定度量以确定度量是否超过阈值，并且基于所评估的度量改变移动性状态。
