[0039] 方案一:绝对用户优先级调度: [0039] Option One: absolute priority scheduling users:

[0040] 完全按照用户与运营商签订的服务等级高低顺序由高到低选取用户,对同一用户下的多条业务连接(如果存在的话)按照协议规定的优先级顺序进行调度。 [0040] The order in full accordance with service-level users and operators signed descending selected users, connected to multiple services at the same user (if any) to be scheduled in order of priority specified in the agreement. 具体说明如下: Specified as follows:

[0041] 用户接入时根据其服务等级保存在不同优先级的队列中,用户下保存其建立的不同业务优先级的业务连接。 [0041] According to its service level connection is stored in different priority queues, to save the user service that establishes a different priority user to access the service. 每个周期的调度顺序:首先从用户服务等级最高的队列中选取MS,对其下的业务连接按照协议规定的五种业务类型的优先级顺序进行调度,即:UGS > ertPS > rtPS > nrtPS > BE,直至该MS下的连接均调度完毕;再选该服务等级中的下一个MS对其业务连接进行调度,直至服务等级最高的用户队列下的MS全部调完;然后再从用户服务等级次高的队列中选取MS,对它的业务连接进行调度;直至所有优先级队列下的MS调度完成或者本次带宽全部耗尽。 Order of each scheduling period: the first user is selected from the queue with the highest level of service the MS, its connection service when scheduling according to the priority of the five kinds of predetermined service type protocol, i.e.: UGS> ertPS> rtPS> nrtPS> bE, until the connection at the MS are completed scheduling; then select the next service in the MS with a service level scheduling is connected, until the MS at the highest level of service the queues are transferred End user; then service level from a user views high MS selected queue, scheduling its traffic connection; MS until all the scheduling priority queue or complete depletion of this band width. 不同服务等级的MS间按服务等级高低依次调度,相同服务等级的MS间按轮转算法依次调度,每调完一个MS将其移入该服务等级队列的队尾,每次调度从队列的队首开始调度。 MS between different service levels according to the level of service level scheduling order, the same grade of service between the MS by Round Robin scheduling order, a completion of each MS to tune into the end of the queue service class, each scheduling starts from the first queue out scheduling.

[0042] 方案二:相对用户优先级: [0042] Scheme II: the relative priority of the user:

[0043] 用户在接入时将其与运营商签订的合同中的服务等级作为用户的一个基本参数保存在用户属性文件中。 [0043] When the user access to the service level agreement signed with its operators as a basic parameter of the user stored in the user properties file. 当用户建立业务连接时,根据其业务优先级(按照UGS > ertPS > rtPS > nrtPS > BE的顺序)与用户服务等级映射出一个连接优先级P,并将业务连接保存在相应的连接优先级队列下。 When a user establishes a service connection, according to its traffic priority (according UGS ertPS rtPS nrtPS> sequence of BE>>>) with a mapping of service level a user connection priority P, and stored in the corresponding service connection priority queue connection under. 调度时按照连接优先级顺序依次调度各业务连接,首先从优先级最高的队列中选取连接进行调度,直到此优先级队列下的所有连接都调度完毕;然后从下一优先级队列中选取连接调度,以此类推,直到所有的连接都调度完毕或者本轮调度带宽耗尽。 Scheduling scheduling order according to the order of connection priority service connection, select the first connection scheduled from highest priority queue, until the all the connections in the priority queue scheduling is completed; and selecting from the next connection scheduling priority queue and so on until all connections are completed or scheduled round of scheduling the bandwidth consumed. 对于相同优先级队列下的连接按照轮转算法调度,每调完一个连接将其移入该优先级队列的队尾,每次调度从队列的队首开始调度。 For connections in the same priority queue according to the Round Robin scheduler, each connected to a complete transfer into the priority queue tail team, each scheduling starts from the first dispatch queue out.

[0044] 采用本发明提出的业务调度,既能体现协议规定的业务类型又能体现用户的服务级别,为运营商提供不同等级的QoS保证提供了解决方案,能够最大限度地满足运营商和用户的需求。 [0044] The present invention is proposed service schedule, service type, which reflects a predetermined protocol but also reflects the level of service the user, provides a solution to provide different levels of QoS guarantee operators, able to satisfy the user and operator It needs.

[0045] 优选实施例一 [0045] The preferred embodiment of a

[0046] 绝对用户优先级调度: [0046] user absolute priority scheduling:

[0047] 首先,用户在初始接入时根据其服务等级将用户挂在相应的服务等级队列中(1 〜MAX)。 [0047] First, a user at the initial access according to its service class corresponding to the user service level hanging queue (1 ~MAX).

[0048] 调度流程结合图2说明如下: [0048] scheduling process explained in conjunction with FIG. 2 as follows:

[0049] 步骤S202,表示服务等级的变量C初始化为MAX ; [0049] step S202, initializing a variable representing the service level to C MAX;

[0050] 步骤S204,在变量C所指示的服务等级队列中获取第一个未调度过的MS,若队列中第一个MS被标记为已调度,则返回空; [0050] step S204, acquires the first MS had unscheduled service level in a queue indicated by the variable C, the first MS, if the queue is marked as scheduled, then return null;

[0051] 步骤S206,判断获取的MS是否为空,若是则转入步骤S208,否则,获取到MS则转入步骤S212 ; [0051] step S206, determines whether the acquired MS is empty, if the process proceeds to step S208, otherwise, to obtain the MS proceeds to step S212;

[0052] 步骤S208,将服务等级标志变量C减1 ; [0052] step S208, the service level flag variable minus 1 C;
