Embodiment Construction

[0049] The present invention considers real-time and non-real-time data types under the condition of ensuring the quality of service (QoS), and proposes a mechanism for extending the sleep time of the mobile device to achieve the purpose of power saving. In the embodiment of the present invention, according to the third power saving mode in IEEE 802.16e, the duration of "sleep / awake" is aperiodic, and the state of the mobile device in sleep or listening depends on the traffic load. Based on the similar operation concept of "traffic load and QoS requirements", a power saving mechanism that can dynamically adjust the sleep time of mobile devices is proposed.

[0050] by image 3 An example is used to illustrate the method of dynamically adjusting the sleep / wake schedule of the wireless network device for periodic linking. Assume that the mobile device MSS B has three unsolicited grant service (UGS) links UGS1, UGS2 and UGS3, and its data characteristics are represented by two p...

Abstract

The invention relates to a system and a method for dynamically regulating a dormant / waking time course of a wireless network device. The system comprises at least one base station and at least one wireless network device, wherein the base station properly delays and combines data transfer by the method to dynamically regulate the dormant / waking time course so that the wireless network device can be in a dormant mode after completing the data transfer in a regulated waking time course. The invention can decrease the number of waking frames positioned on a mobile device terminal under the condition of meeting the requirement for service quality.

Description

technical field [0001] The present invention relates to a system and method of a wireless communication device, and in particular to a system and method for saving power by dynamically adjusting the sleep / wake schedule of a wireless network device. Background technique [0002] Worldwide Interoperability for Microwave Access (WiMAX) is an emerging wireless broadband network system. The operation of the system mainly adopts the 802.16 related standards formulated by the International Institute of Electrical and Electronics (IEEE). In addition, the IEEE 802.16e standard was newly formulated in 2005 to meet the needs of mobile wireless communications. The IEEE 802.16e standard has attracted much attention in the Broadband Wireless Access (BWA) technology because of its superior features such as high bandwidth, high mobility, wide area coverage, and link quality assurance. [0003] In the IEEE 802.16e standard, the connection between the base station (Base Station, BS) and the ...
