Description

一种实现分组数据优先业务的方法 A method for implementing priority packet data traffic

技术领域 FIELD

本发明涉及第三代合作伙伴计划(3GPP)网络分组数据业务的处理技术,特别涉及一种实现分组数据优先业务的方法。 The present invention relates to the Third Generation Partnership Project (3GPP) network packet data service processing techniques, particularly the method relates to a packet data service priority one implementation.

背景技术 Background technique

随着移动用户对移动网络服务质量的要求不断上升,根据不同目标移动用户群体提供不同的服务质量,已成为运营商普遍关注的课题。 As mobile users demand for mobile network service quality rising, provide different quality of service depending on the target mobile user groups, it has become a topic of common concern operators. 优先业务服 Priority business suits

务已成为越来越多运营商提高移动用户满意度的有效手段。 Service has become more and more effective means of mobile operators to improve customer satisfaction. 优先服务是指将 Priority Service refers to the

移动用户分成多个优先业务级别,当移动用户请求优先业务时,网络识别优先业务并根据移动用户的优先业务级别,提供高于普通业务的优先处理。 Mobile users into a plurality of levels of priority traffic, request priority when the mobile subscriber services, network traffic and identify the priority based on the priority level of the mobile service user, providing higher than normal priority traffic. in

网络发生拥塞或资源不足的情况下,高优先业务级别的移动用户发送的优先业务可得到高优先级的处理,满足高优先级移动用户的需求。 Congestion or lack of network resources occurs, high priority service traffic priority class mobile users to send a high priority processing can be obtained, a high priority to meet the needs of mobile users. 目前,3GPP网络支持的语音优先业务的实现方案如下。 Currently, the 3GPP network to support implementation of priority voice traffic as follows. 3GPP网络中的语音优先业务属于一种签约业务,不需要移动用户主动进行注册、退出等操作。 3GPP network voice traffic priority belongs to a subscription service, mobile users do not need to take the initiative to register and exit operations. 允许哪些移动用户使用优先业务和设置移动用户的优先业务级别设置由运营商或其他机构决定。 Which allows mobile users to use business priorities and set the priority level set mobile business users is determined by the operator or other institutions. 3GPP定义的普通移动用户接入级别分为0〜9共IO个等级,11〜15是5个特殊接入级别,分別定义为移动网络使用、安全业务、公共机构人员和运营商内部员工。 Ordinary 3GPP mobile user-defined access levels are divided into a total of IO 0 ~ 9 grades, 11~15 are five special access levels are defined using a mobile network, security business, public agency personnel carriers and internal staff. 每个移动用户的接入级别作为用户签约数据保存在归属位置寄存器(HLR)中,或/和保存在该移动用户的用户标识模块(SIM)中。 Access level for each mobile user as the user subscription data saved in the home location register (HLR) in, and / or stored in the mobile subscriber's subscriber identity module (SIM) in.

具有优先业务级別的移动用户可以针对每次呼叫决定是否发起优先呼叫。 Mobile users have priority service level for each call can decide whether to initiate a priority call. 当该移动用户向汇接网络和收端网络发送优先呼叫请求时,该优先呼叫请求中携带有优先业务标识和该移动用户的优先级别,3GPP网络根据该请求携带的优先业务标识识別该呼叫请求是优先呼叫。 When the mobile user sends a call request to the priority tandem network and terminating network, the priority call request carries the priority service ID and priority of the mobile user, the 3GPP network priority identifying the service identifier carried in the call request based on the request is a priority call.

当发端网络和汇接网络接收到优先呼叫请求后,发端网络和汇接网络中提供特殊的呼叫进展能力,免除限制性的网络管理控制,包括码控制、手工取消控制、自动拥塞控制和中继预留控制,以提高严重拥塞下呼叫完成的可 When the originating network and the network receives the tandem priority call request, the originating network and the network tandem to provide call progress specific capacity, eliminating limiting network management control, including a control code, manual cancellation control, automatic congestion control, and relay reservation control to improve the call completion may be heavily congested

能性。 Possibility. 当汇接网络中的移动交换中心(MSC)占用局间中继电路时,按照优先呼叫请求的优先业务级别高低进行排队;当汇接网络中的移动交换中心(MSC)不占用局间中继电路时,按照排队的顺序依次处理优先呼叫请求。 When the inter-mobile switching center (MSC) in the network tandem office repeater circuit occupancy, traffic according to the priority level of the priority level of the call request queue; when the tandem network between a mobile switching center (MSC) does not occupy Bureau following the circuit, in the order of priority are sequentially processed queued call request. 当发端没有可用的无线信道资源时,根据呼叫优先级和到达时间进行排队; 当发端的无线信道资源可用时,按照排队的顺序依次处理优先呼叫请求。 When the originating wireless channel resource is not available, the call according to the priority and time of arrival queue; originating wireless channel when resources are available, sequentially in the order of the queued requests priority call processing.

优先业务可以应用于所有移动业务,但现阶段3GPP只提供电路交换语音优先业务的实现方案,分组数据优先业务的实现方案却没有提供。 Priority service can be applied to all mobile services, but at this stage only 3GPP implementation provides circuit-switched voice service priority, the priority of packet data implementation does not provide service. 因此, 如何在分组数据业务中实现优先业务是一个亟待解决的问题。 Therefore, how to achieve business priority in the packet data service is a serious problem.
