Embodiment Construction

[0050] figure 1 The overall scheduling process of the IEEE 802.16 MAC protocol:

[0051] The uplink and downlink scheduling process based on the IEEE 802.16 MAC protocol is divided into the following steps:

[0052] S1.1.SS enters the wireless broadband access network, first obtains wireless channel parameters, establishes a physical connection with the base station, MAC layer controls the connection, configures IP address information to complete the network access and initialization process;

[0053] S1.2. SS has upper layer data sent and reaches the service convergence sublayer of the MAC layer. The service convergence sublayer of the IEEE 802.16 MAC layer classifies the upper service data unit SDU (Service Data Unit). The upper data unit is queued according to different connection IDs (CID), and the different CID queues are classified according to priority requirements;

[0054] S1.3. Different upper data units enter the upstream data buffer according to the classification re...

Abstract

The method includes following steps: 1) SS accesses the radio access network; 2) SS has upper layer data for transmitting; 3) the different upper layer data unit enter the upstream data buffer area; 4) SS requests the band width for connection requiring upstream band width; 5) the base station receives the band width request messages from each SS; 6) BS passes through the dispatching module of up data link on base station; 7) the base station composes the result of up data link dispatch into UL_MAP message and informs transmitting time slot and time slot length of upstream data of each SS; 8) the downstream message of BS transmitted through downstream link dispatcher is sent to SS. 9) SS receives the data transmitting time slot granted by BS; 10) BS is dispatched through upstream data of SS, and implements the dispatch process, and then return to 2).

Description

Technical field [0001] The invention relates to the technical field of broadband wireless access networks, in particular to a terminal uplink scheduling method for voice services in a broadband wireless access network. It is a data scheduling method that provides uplink channel allocation for IEEE802.16-based terminals (outdoor access units) to ensure real-time voice service quality in the access network. Background technique [0002] The user's demand for high-speed Internet access and multimedia services has greatly promoted the development of broadband access technology. Broadband Wireless Access (BWA) as a new broadband access technology has many advantages. For example, rapid deployment, high scalability, low maintenance and upgrade costs, etc. In order to establish a high-performance broadband wireless access system, people have done a lot of work in the research and standardization of broadband wireless access technology. IEEE802.16 is an important international technical ...
