Abstract
The classification of service (CoS ) is made on 802.16 network. Combining the feature of 802.16 supporting QoS communication service, band width is distributed to different class service to ensure the service quality of speech communication. Different class service has different size band width and different priority. The service in high priority is permitted to occupy bandwidth used by service in low priority. Call in mobile switch process has higher priority, and is distributed bandwidth from pre-reserved bandwidth. Emergency call, switch call and switch QoS data service are set into four FIFO queues. When there is bandwidth is released, the bandwidth is distributed to service in these four queues based on different priority. When newly generated ordinary call and data service can not get bandwidth, they will be rejected to access the network.
Description
Technical field
The invention belongs to broadband wireless MAN (IEEE 802.16 WirelessMAN) technical field, is a kind of bandwidth allocation methods that class-of-service is provided in 802.16 networks.
Background technology
802.16 WirelessMAN is a kind of broadband network [1] Carl Eklund that can provide high-speed radio to insert in the metropolitan area scope, Roger B.Marks, " IEEE Standard 802.16:ATechnicalOverview of the WirelessMAN
TMAir Interface for Broadband WirelessAccess ", IEEE C802.16-02/05,2002.IEEE 802.16 working groups have issued IEEE Std 802.16-2004 on October 1st, 2004, this standard definition work in the fixed broadband wireless access system air interface physical layer (PHY) and media access control layer (MAC) standard [2] the LAN/MAN Standards Committee of 2-66GHz frequency band, " Part 16:Air Interface for fixedBroadband Wireless Access Systems ", IEEE Std 802.16
TM-2004.IEEE Std802.16e will be in March, 2005 issue, this standard definition the air interface specification of mobile wide-band wire-less accessing system.The air interface specification that IEEE 802.16 working groups formulate has proposed the professional support to QoS (Quality of Service), but bandwidth allocation methods is not made stipulations.In recent years, speech business becomes a most important component on the Radio Access Network, and therefore, the bandwidth allocation methods on 802.16 networks should preferentially guarantee the service quality of speech business.
Summary of the invention
The object of the present invention is to provide a kind of bandwidth allocation methods that class-of-service is provided in broadband wireless MAN, in conjunction with the characteristic of 802.16 agreements support QoS business, for the user provides a kind of broadband wireless access mode that service quality guarantees that has.
802.16 medium access control (MAC, Media Access Control) layer utilizes service flow (Service Flow) to provide data transport service to the upper strata.802.16 in service flow be divided into three kinds: (provisioned) service flow, access (admitted) service flow and activity (active) service flow are provided in advance.These three kinds of service flow all have a service flow identifier (SFID, Service FlowIdentifier), the two kinds of service flow in back also have a connection identifier (CID (CID corresponding with SFID, Connection Identifier), preceding two kinds of service flow all are not assigned with bandwidth, be called as non-activity service stream, have only activity service stream to have the bandwidth of being asked.
The bandwidth allocation methods that the present invention proposes is moved on 802.16 base stations, is descending (from the base station to the terminal) activity service stream and up (from the terminal to base station direction) activity service flow distribution bandwidth.When base station requests and terminal are set up a descending activity service stream, when perhaps base station requests is changed to active state with descending non-activity service stream, the base station produces bandwidth allocation request, and the method for utilizing the present invention to propose is distributed bandwidth for this descending service flow, makes it to become descending activity service stream.When a up activity service stream is set up in terminal request and base station, when perhaps the terminal request base station is changed to active state with up non-activity service stream, the base station produces bandwidth allocation request, utilizes method that the present invention proposes for this upstream service flow distributes bandwidth, makes it to become up activity service and flows.
The present invention will be divided into two classes in the business of transmission over networks: speech business and data service.Speech business is divided into two grades: urgent call and ordinary call; Data service is divided into two grades: QOS data service and general data business.The grade of service of speech business is higher than data service, and the priority of urgent call is higher than ordinary call, and the priority of QOS data service is higher than the general data business.In addition, the speech business priority of switching is higher than new voice calls business, and the QOS data service priority of switching is higher than new generation data service.Service switchover is meant from other base station by mobile handoff procedure and arrives this service in base station.
The present invention is divided into bandwidth reserved, new urgent call bandwidth, new ordinary call bandwidth, QOS data bandwidth and general data bandwidth with wireless bandwidth.Bandwidth reserved is used for switched voice call, bandwidth reserved can be reserved by static and dynamic mode, the static reservations mode is promptly reserved the bandwidth of a part of fixed size in advance and is used for switched voice call in total bandwidth, dynamically reservation mode is promptly dynamically adjusted the aggregate reservation amount of bandwidth according to already used bandwidth reserved size, and the RSVP method is not within the scope of the present invention.New urgent call bandwidth is to remove the urgent employed part of switch call in the bandwidth reserved in whole bandwidth, i.e. urgent call has limit priority, can seize the professional employed bandwidth of data service and ordinary call.New ordinary call bandwidth is the bandwidth except that bandwidth reserved, i.e. speech business can be seized the bandwidth that data service is used, and bandwidth reserved only uses for switching speech business and emergence call service, and new ordinary call business can not take bandwidth reserved.The QOS data bandwidth is the part except that bandwidth reserved and the new ordinary call bandwidth just used.The general data bandwidth is to remove the current part that is just being taken by the voice-and-data business in whole bandwidth, be that the general data business can be used the part that is not used in bandwidth reserved and the non-bandwidth reserved, in case but these bandwidth are used by speech business and QOS data service request, the general data business should be given back these bandwidth immediately, the general data business guarantees without any service quality, switches the professional and new general data business that produces of general data and has identical priority.
The present invention requires to safeguard four bandwidth request queue: urgent switching queue, urgent call formation, common switching queue, QOS data switching queue.Urgent switching queue will move the urgent call of failing to obtain bandwidth immediately that switches to this base station and rank according to the order of first in first out, wait for allocated bandwidth.The urgent call formation is waited for allocated bandwidth with the order queuing according to first in first out of the new emergency call request of failing to obtain bandwidth immediately of this base station.Common switching queue will move the ordinary call request of failing to obtain bandwidth immediately that switches to this base station order queuing according to first in first out, wait for allocated bandwidth.QOS data switching queue will move the QOS data service of failing to obtain bandwidth immediately that switches to this base station order queuing according to first in first out, wait for allocated bandwidth.These four bandwidth request queue are being safeguarded a timer respectively, this timer record the deleted moment of each element of place formation, work as timer expired, respective element is deleted from formation.The timeout value of each timer is separate, and the timeout value of timer is decided by practical application.The allocated bandwidth priority of these four bandwidth request queue is successively decreased according to the order of urgent switching queue, urgent call formation, common switching queue and QOS data switching queue.New ordinary call that produces and data service obtain under the situation of bandwidth immediately failing, and do not need queuing, are denied access to network.
When bandwidth allocation module is received bandwidth allocation request, be that corresponding service flow is distributed bandwidth according to the flow process of Fig. 1.Wherein, idle bandwidth is defined as the bandwidth of not used by other business that bandwidth request can be used; Bandwidth-hogging is defined as bandwidth that bandwidth request can be used but that used by other business; Speech bandwidth is defined as the professional shared bandwidth of current speech; The ordinary call definitions of bandwidth is the employed bandwidth of ordinary call in the speech bandwidth (comprise and switch ordinary call and new generation ordinary call).
When bandwidth allocation module has bandwidth to discharge, handle according to the flow process of Fig. 2.
The present invention only is divided into four grades with the business on the network, in fact, according to thought of the present invention, is easy to the method that the present invention proposes is expanded to the business of the more grades of support.
