    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) cell. 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. A method for updating TA upon expiration of timer (set up based on mobility state. Paging load).

    Abstract: A method and a wireless transmit receive unit, WTRU, for performing measurements for cell reselection are disclosed. Priority information is received via a system information broadcast, wherein the priority information is indicative of cell reselection priority information for an inter-radio access technology, RAT, cell associated with a candidate RAT. A relative priority is determined of the inter-RAT cell associated with the candidate RAT with respect to a current cell associated with a current RAT based on the priority information. Furthemore, cell reselection measurements are performed on the inter-RAT cell in the candidate RAT, wherein the cell reselection measurements are performed based on at least one of the inter-RAT cell associated with the candidate RAT having a higher relative priority than the current cell associated with the current RAT, or a quality of the current cell being less than or equal to a predetermined threshold if the inter-RAT cell associated with the candidate RAT does not a have a higher relative priority than the current cell associated with the current RAT.

    Abstract: A METHOD AND APPARATUS FOR PROVIDING WIRELESS COMMUNICATION SERVICES, (E.G., MULTIMEDIA BROADCAST MULTICAST SERVICES, MBMS), ARE DISCLOSED. A WIRELESS TRANSMIT/RECEIVE UNIT, WTRU DETECTS A PLURALITY OF TARGET CELL EVOLVED NODE-BS, ENODEBS THAT NEIGHBOR A SERVING CELL ENODEB (110). THE WTRU (400) EVALUATES CELL RESELECTION CRITERIA AND DETERMINES A NEIGHBORING TARGET CELL ENODEB TO RESELECT. THE WTRU (400) RECEIVES AND READS MASTER INFORMATION BLOCK, MIB AND SYSTEM INFORMATION MESSAGES OF THE NEIGHBORING TARGET CELL ENODEB (500), AND CONFIRMS THAT THE DETERMINED NEIGHBORING TARGET CELL ENODEB IS NOT PART OF A MULTIMEDIA BROADCAST SINGLE FREQUENCY NETWORK, MBSFN. THE WTRU (400) IDENTIFIES THE NEIGHBORING TARGET CELL ENODEB TO THE SERVING CELL ENODEB (110). THE WTRU (400) THEN RECEIVES AND READS MIB MESSAGES OF THE NEIGHBORING TARGET CELL ENODEB AGAIN TO DETERMINE WHETHER THE SYSTEM INFORMATION HAS CHANGED AND, IF SO, THE WTRU (400) READS THE SYSTEM INFORMATION AND RESELECTS TO THE NEIGHBORING TARGET CELL ENODEB (500), WHICH PROVIDES THE WIRELESS COMMUNICATION SERVICES.
