Abstract: Identifier-sharing methods for wireless communication devices are proposed along with wireless communication devices and base stations using the same method. The proposed methods allow multiple M2M devices to share the same device identifier. The shared device identifier is valid for only one M2M device in a given time interval by a mechanism of assigning the same periodicity value and different offset values to the M2M devices associated with the shared device identifier. The proposed methods can also categorize M2M devices into different classes respectively based on their M2M application types. By adjusting periodicity value associated with the shared device identifier, a class associated with delay-tolerable applications can be allocated with more M2M devices sharing the same device identifier in comparison to the another class associated with delay-sensitive applications.

Abstract: A method is provided for a device in a wireless communication network including a base station. The method includes sending a sleep mode request to the base station; and receiving a sleep mode response including negotiating parameters from the base station. The method also includes entering a sleep mode determined by a single power saving class applicable to all traffic conditions between the device and the base station; and communicating with the base station based on the sleep mode. Further, the single power saving class is used to define a frame structure for configuring frames to form alternating listening windows and sleep windows, to define an initial sleep window, and to define a default listening window.

Abstract: A communication system is disclosed which includes a communication network having a paging controller and a plurality of base stations to communicate with at least one mobile client device within the system. Also included in the communication system is a base station, between the plurality of base stations, receiving location updates from the at least one mobile client device; and a processor within the paging controller to accumulate the number of location updates relayed by the base station for each mobile client device, wherein the processor determines whether the accumulated number of location updates received exceeds a predetermined threshold number of location updates. The plurality of base stations each broadcast paging messages to the at least one mobile client device when the predetermined threshold number of location updates is not exceeded.

Abstract: A signal transmission method, and a base station and a wireless communication device using the same station identifier are provided. The signal transmission method is adapted for a M2M device, and includes the following steps. A M2M device is configured as either a follower device or a leader device, and the M2M device is grouped into a M2M device group comprising a leader device and n follower device, where n>=0. Moreover, a M2M contention region is periodically broadcasted in radio frames, where the follower device joins the M2M group by attaching to the leader device in the M2M device group during the M2M contention region. In addition, M2M devices in same M2M device group share same station identifier.
