技术领域 FIELD

本发明涉及通信领域,特别涉及一种生成业务分流策略的方法、装置及系统。 The present invention relates to the field of communications, particularly to a method, apparatus and system for generating a service shunt strategy.

背景技术 Background technique

目前,在异构网络环境下,多种无线接入技术共存,多模终端可以通过多个接口同时与多个网络建立连接。 Currently, in the heterogeneous network environment, the coexistence of multiple wireless access technologies, the multimode terminal can simultaneously establish a connection with a network via a plurality of the plurality of interfaces. 多连接技术为用户提供了无缝的网络接入服 Multi-connector technology to provide users seamless access to network services

务,用户可以通过多模终端在多条链路上发送同样的数据,使得通信的可靠性得以大幅度提升,另一方面,用户也可以通过多模终端在多个网络间合理分配业务流,使得网络间在一定程度上实现了负载均衡,从而提高网络资源利用率。 Service, the user may be transmitted through the multimode terminal in the same data links, so that the reliability of communication is improved significantly, on the other hand, the user can assign a reasonable traffic flow between a plurality of networks by multi-mode terminal, It allows load balancing between networks to some extent, thereby improving the utilization of network resources.

例如,参阅图1A所示, 一个用户终端(即多模终端)同时与多个接入网络相连。 For example, as shown in see Figs. 1A, a user terminal (i.e., multi-mode terminal) is connected to a plurality of access networks at the same time. 用户终端使用两个不同的地址(地址1和地址2 )与接入网1同时保持两个链接, 此外,用户终端还分别使用地址3和地址4与接入网2和接入网3相连,这样,用户终端便通过三个接入网同时与连接到IP骨干网。 User terminal uses two different addresses (address 1 and address 2) with an access network while maintaining the two links, in addition, the user terminal further 3 were used and the address Address 4 2 is connected to the access network and the access network 3, Thus, the user terminal will access network by three simultaneously connected to the IP backbone network. 这样,便通过在多个网络上传输业务流实现了带宽的汇聚,从而获得更高的数据传输速率和QoS支持。 Thus, it is passed over a plurality of network transmission traffic flows to achieve bandwidth aggregation, resulting in higher data rates and QoS support.

在欧盟的端到端重新配置(E2R)项目中,基于互联网工程任务组(IETF) 的多链路概念提出了自适应无线多链路(ARMH)的管理框架。 In the end the EU reconfiguration (E2R) project, based on the Internet Engineering Task Force (IETF) proposed the concept of multi-link adaptive wireless multilink (ARMH) management framework. 它允许多模/ 多频终端能够同时与多个接入网相连。 It allows a multi-mode / multi-band terminals can be simultaneously connected to a plurality of access networks. 根据各个子网、终端、用户和业务的信息,选择最合适的联合无线资源管理功能。 According to various subnets, terminal, user and service information, choose the most appropriate joint radio resource management functions. 业务的分类、服务应用服务器和无线资源控制器的交互、传输格式的配置以及MAC协议都由ARMH进行管理。 Interaction, transmission format configuration and MAC protocol classification services, application servers and service radio resource controller by ARMH management.

E2R的自适应无线多链路提出了同一个业务流的分流机制,同时由网络侧进行业务分流的控制,有利于从网络角度实现真正意义上的负载均衡。 Adaptive wireless multilink E2R proposed diversion mechanism the same traffic flow, traffic diversion simultaneously controlled by the network side, is conducive to load balancing in the true sense from a network perspective. 但缺点在于其的,并且拥有共同的资源管理控制实体(如图1B中的RNC),业务分流由这个实体发起和控制。 But its disadvantage, and have a common resource management control entity (RNC shown in FIG. 1B), by a service distribution entity initiated and controlled.

但是,在实际的应用场景中,通信系统的网络环境很难达到理想的紧耦合关系,并且覆盖用户终端的各个接入网之间通常不存在共同的管理实体。 However, in actual application scenario, the communication system network environment is difficult to achieve the desired tightly coupled, and the common covering managing entity generally does not exist between the respective access network user terminal. 在未 Without

网的无线资源管理实体之间通过信息交互进行协同工作,实现资源管理的优化。 Collaborative work through the information exchange between the radio resource management entity network, optimize resource management. 在这样的网络环境下,当用户终端发起业务请求时,如何从而实现多网络业务分流是个悬而未决的问题。 In such a network environment, when the user terminal initiates a service request, how to achieve multi-service distribution network is an open question. 由于各个接入网之间不存在共同的管理实体, 因此缺乏对业务分流进行有效控制的方案,对于如何在这样的网络环境下实现多网络协作生成业务分流策略这一问题,目前还没有切实可行的解决办法,因而也无法真正实现异构网络间业务分流的实施。 As the common management entity does not exist between the various access networks, so the lack of effective control programs for service distribution, how to achieve multi-generation web collaboration service shunt strategy in such a network environment this problem, there is no practical solutions, and therefore can not truly heterogeneous service distribution network implementation.

其中上述系统架构,如图2所示,本实施例中,以分布式异构通信系统包含两个采用不同无线制式的接入网络为例进行介绍,分别称为接入网l和接入网2,相应地,将分别归属于接入网1和接入网2的无线资源管理装置21分别称为CRRM 1和CRRM 2,通常情况下,用户终端20默认的接入网络可以由用户根据自身的使用习惯自行设定,本实施例中,将用户终端20默认的接入网络设置为接入网1,即用户终端20默认归属于CRRM 1管控;而CRRM 1 和CRRM 2通过信息交互在异构通信系统之间实现了联合接纳控制功能。 Wherein said system architecture, shown in Figure 2, in this embodiment, a distributed heterogeneous communications system comprising two different radio access network standard described as an example, referred to as an access network and an access network l 2, respectively, are attributed to the access network and the access network 1 2 radio resource management apparatus 1 and 21 are referred to as the CRRM the CRRM 2, usually, the default access network 20 the user terminal by the user according to their own set their own habits, in this embodiment, the user terminal 20 is set to the default access network the access network 1, the user terminal 20 that is the default control attributable to the CRRM 1; and the CRRM CRRM 2 by 1 and information exchange in a heterologous admission control function to achieve a joint between the communication system configuration.

在实际应用中,分布式异构通信系统还可以包括两个以上采用不同接入技术的接入网,本实施例仅以图2所示网络环境为例进行介绍。 In practice, a distributed heterogeneous communications system may also include more than two different access network access technologies, the present embodiment only the network environment shown in FIG. 2 described example.

除上述功能实体外,如图2所示,分布式异构通信系统中还可以包括: 基站,归属于各接入网,用于将来处于IP骨干网的业务流转发至用户终端20,或者将来自去用户终端20的业务流发往IP骨干网; 网关,用于实现名4妾入网与IP骨干网的连接; 多模终端通信对端,用于和用户终端20进行远程通信。 In addition to the functional entities shown in Figure 2, a distributed heterogeneous communications system may further comprises: a base station, belonging to each access network for future traffic flow is sent to the IP backbone network user terminal 20, or from 20 to user terminal traffic stream sent to the IP backbone network; gateway for realizing the connection name concubine 4 and IP backbone network; multimode terminal to the communication terminal, and the user terminal 20 for remote communication. 参阅图4所示,本实施例中,用户终端20在接入分布式异构通信系统时, 其默认归属的CRRM 1对其进行接纳控制的详细流程如下: Referring to FIG. 4, a detailed example, the user terminal 20 when accessing distributed heterogeneous communication systems, the default home CRRM 1 subjected to admission control of the present embodiment is as follows:

步骤400: CRRM1接收用户终端20发送的业务请求消息,该业务请求消息中携带业务类型信息(至少包含用户服务质量QoS需求)。 Step 400: the service 20 sends the receiving user terminal CRRM1 request message, the service request message carries service type information (including at least user quality of service QoS requirements).

本实施例中,用户终端20在空闲状态下默认驻留在接入网1中,那么,当用户终端20发起新的会话请求时(即向CRRM 1发送新的业务请求消息), 管理接入网1的CRRM 1便对用户终端20进行接纳控制,为用户终端20发起的会话请求选择一个或至少两个采用不同接入技术的接入网络进行接入。 In this embodiment, the default user terminal 20 residing in the access network 1, then the terminal 20 when the user initiates a new session request (ie the CRRM a message sends a new service request) in the idle state, the access management 1, web 1 will CRRM user admission control terminal 20, the user terminal 20 initiates a session request to select one or at least two different access technologies of the access network to access.

另一方面,本实施例中,用户终端20在发送的业务请求消息中还携带有各个接入网络的下行信道状态信息,下行信道状态信息用于表示当前下行无线信道的链路质量(如,路径损耗),下行信道状态信息由用户终端20进行测量, 并报告给CRRMl,上行信道状态信息由网络侧进行测量。 On the other hand, in this embodiment, the user terminal 20 transmits the service request message further carries the respective access network downlink channel state information, the downlink channel state information indicating the current link quality of downlink wireless channel (e.g., path loss), the downlink channel state information measured by the user terminal 20 and reports to CRRMl, uplink channel state information measured by the network side. 此外,用户终端20 在业务请求消息中还可以携带用于指示自身是否支持业务分流的标识信息,若用户终端20受功能限制不支持业务分流,那么,即使其请求的业务可以进行分流,CRRM1也不对其进行业务分流的接纳控制。 In addition, the user terminal 20 in the service request message may carry further used to indicate whether the service shunt itself supports the identification information, when the user terminal 20 is not supported by the service distribution function limit, then, even if the requested service can be split, CRRM1 also not its admission control of traffic diversion.

步骤410: CRRM l才艮据预设的接纳策略判断用户终端20请求的业务类型是否可进行分流;若是,则进行步骤420:否则,进行步骤470。 Step 410: CRRM l Gen only admission policy is determined according to a preset user terminal 20 requests the type of service whether shunt; if yes, Step 420: Otherwise, step 470.

本实施例中,CRRM1从策略库中获取预设的接纳策略,并结合业务请求消息中携带的业务类型信息对该业务进行分流判断,例如: In this embodiment, CRRM1 acquired from the policy repository preset admission policy, and service type information in conjunction with the service request message carries the traffic of the shunt is determined, for example:

若用户终端20请求的业务类型为普通语音业务,则直接进行常规接纳控制,无需进行业务分流; If the user terminal 20 requests the service type is a general voice service, the conventional admission control directly, without the need for a service shunt;

若用户终端20请求的业务类型为要求较高传输带宽的视频业务、FTP业务等,则需要指示用户终端20将请求的业务流分割成多条业务子流,并通过多个接入网络进行传输; If the user terminal 20 requests the type of service required high transmission bandwidth for the video service, FTP service, etc., it is necessary to instruct the user terminal 20 requests the service stream is divided into a plurality of sub-stream service, and transmitted through a plurality of access networks ;

步骤420: CRRM l在策略库中获取与业务类型信息相匹配的分流建议信息,在本地获取接入网l的网络环境信息以及接收CRRM2发送的接入网2的网络环境信息。 Step 420: CRRM l diversion advice information acquiring type information matches the service policy in the library, the network environment information acquired in the local access network l network environment information and the access network 2 receives CRRM2 transmitted.

本实施例中,对应各业务类型信息预设的各种分流建议信息保存在策略库内,CRRM l可以根据业务请求消息中携带的业务类型信息来获取对应的分流建议信息,分流建议信息的内容可以通过如下方式设置: In this embodiment, corresponding to various types of information split recommended service information stored in the preset library policy, CRRM l diverter may be acquired advice information corresponding to the request message carries service type information according to the service, the content recommendation information shunt You may be provided by:

会话类业务:对于实时性较强的会话类业务,可以不进行分流,或者按照控制信令业务子流与业务数据业务子流两部分进行分流; Session services: real-time session services for strong, may not be split, or sub-stream and traffic data stream traffic split in two parts in accordance with sub-control signaling traffic;

流媒体业务:可以按照视频业务子流与音频业务子流两部分进行分流,或者按照基本层业务子流和增强层业务子流进行分流; Streaming service: video service can flow according to an audio stream and the sub-service sub-section two shunt, or flow splitter according to the basic stream and an enhanced layer service sub-sub-layer services;

交互类业务:可以:換照主(main objects )对象业务子流和协调(inline) 对象业务子流两部分进4亍分流,典型的应用如HTTP业务; Interactive class traffic: can: change as the primary (main objects) and the objects coordination service sub-flows (inline) target service sub-flows into two portions split right foot 4, a typical business applications such as HTTP;

后台类业务:典型的应用如Ftp业务,由于Ftp业务的同质性(即业务整体具有同样的QoS需求),因此,Ftp业务流可以进行任意分割。 Background class traffic: Typical business applications such as Ftp, since homogeneity Ftp business (i.e. the business as a whole has the same QoS requirements), and therefore, Ftp traffic stream may be arbitrarily divided.

步骤430: CRRM1根据获得的分流建议信息,结合接入网l和接入网2的网络环境信息生成对应的业务分流策略。 Step 430: CRRM1 diversion recommendation information according to the obtained binding l access network and the access network 2 to the network environment information to generate a corresponding service shunt strategy.

例如,用户终端20当前请求的业务为视频业务,CRRM1获得的分流建议信息指示将该视频业务的业务流划分为视频子流和音频子流,该视频子流和音频子流分别具有不同的QoS需求(包含时延要求、速率要求等);接着,CRRM l根据视频子流和音频子流各自的QoS需求查找相应的适性因子值,即结合接入网l和接入网2的网络环境信息为视频子流和音频子流分别选择最适合的接入网络进行传输,从而实现分流接入控制。 For example, the current shunt 20 advice information service request for the video service terminal user, CRRM1 obtained indicates the traffic stream into a video sub-service video stream and an audio sub-stream, the video stream and the sub-audio substreams having different QoS are requirements (including delay requirement, speed requirements, etc.); then, the CRRM l streams each corresponding QoS requirements lookup fitness factor value in accordance with the sub-audio and video sub-stream, i.e., in conjunction with the access network and the access network network environment l 2 transmission of the video information and the audio sub-streams the sub-streams were selected as the most suitable access network, to achieve the split-access control.

步骤440、 CRRM1将生成的业务分流策略发往用户终端20,以指示用户终端20对其请求的业务流进行分流。 Step 440, CRRM1 shunt strategy generated traffic addressed to the user terminal 20, terminal 20 to indicate that the user is requested to divert traffic flow.

本实施例中,用户终端20在对业务流进行分流之前,需要先和CRRM2建立网络连接,CRRM l会在业务分流策略中将CRRM 2的相关信息通知用户终端20,以便其与CRRM2建立网络连接;在与CRRM2建立网络连接后,用户终端20对自身请求的业务流进行分流,并将得到的各业务子流分别通过CRRM l和CRRM 2进4于上传。 In this embodiment, the user terminal 20 prior to divert traffic flow, and need to establish a network connection CRRM2, CRRM l 2 session information informing the user terminal 20 will shunt the CRRM business strategy, in order to establish a network connection to which CRRM2 ; after establishing a network connection with CRRM2, the user terminal 20 itself requested service stream split, and each service sub streams obtained by CRRM l, respectively, and feed 4 CRRM 2 uploading.

步骤450: CRRM1将生成的业务分流策略发往CRRM2。 Step 450: CRRM1 The shunt strategy generated traffic destined CRRM2.

步骤460: CRRM2执行CRRM1下发的业务分流策略,与用户终端20建立连接,并接收用户终端20上传的分流后的业务子流。 Step 460: CRRM2 CRRM1 delivered by the executed service shunt strategy, the user terminal 20 establishes a connection, and the user terminal 20 receives upload service After the split streams.

步骤470: CRRM1对用户终端20进行常规的接纳控制,无需指示其对业务流进行分流。 Step 470: CRRM1 the user terminal receiving the control routine 20, which indicates no need for the service stream split.

基于上述实施例,参阅图5所示,在步骤430中,当CRRM1确定需要指示用户终端20对其业务流进行分流时,CRRM1依据获取的分流建议信息,结合接入网l和接入网2的网络环境信息生成对应的业务分流策略的详细流程如下: Based on the above embodiment, as shown in FIG. 5, in step 430, when the user terminal indicating CRRM1 20 determines that its traffic flow shunt, shunt according CRRM1 advice information acquired in conjunction with the access network and the access network 2 l the network environment information to generate a corresponding service shunt strategy detailed flow is as follows:

在实际应用中,CRRM l可以在策略库中获取分流建议信息,或者,若管理人员将分流建议信息预先设置在各CRRM中,CRRM l也可以在本地获耳又所需的分流建议信息,本实施例仅以在策略库中获耳又分流建议信息为例进行介绍。 , CRRM l can get in practical applications in the Policy Library shunt suggestions information, or if management will recommend diversion information provided in advance in each CRRM, CRRM l can be obtained locally and needed ear shunt suggestions information, this Example ears only won in the policy library and information shunt recommend introduces an example.

另一方面,在上述实施例中,步骤500、步骤510和步骤520均可以周期性执行,并且没有严格的执行顺序,例如,步骤500和步骤510也可以同步执行, 或者先执行步骤510、步骤520,再执行步骤500,同样可以达到理想的技术效果,在此不再赘述。 On the other hand, in the above embodiments, step 500, step 510 and step 520 can be performed periodically, and no strict order of execution, e.g., step 500 and step 510 may be performed synchronously or first step 510, step 520, followed by the step 500, the same technique can achieve the desired effect, which will not be repeated herein.

在上述两个实施例中,CRRM l也可以在接收到用户终端20发送的业务请求消息之前预先从本地获得接入网1的网络环境信息以及从CRRM 2获得接入网2的网络环境信息,这样,在接收到业务请求信息后,CRRM1便可以在本地或者策略库中直接获取分流建议信息,结合接入网1和接入网2各自的网络环境信息来生成对应的业务分流策略,同样可以达到理想的技术效果,在此不再赘述。 In the above two embodiments, CRRM l receiving the service may be sent from the user terminal 20 the network environment information obtained in advance from the local access network before a request message and network environment information obtained from the access network 2 CRRM 2, Thus, after receiving the service request, CRRM1 can directly acquire the information locally or diversion recommendation policy repository, the binding access network and the access network 1 2 each network environment information to generate a corresponding service shunt strategy, can also to achieve the desired technical effect, which will not be repeated here.

另一方面,由于各接入网的网络环境是在不断变化的,因此,各接入网中的CRRM需要按照设定的周期获得自身归属的接入网的网络环境信息,并将其发往其他的接入网络,这样,各CRRM便可以及时获得各接入网络的网络环境信息,从而掌控整个分布式异构通信系统的接入网络状态,以便结合用户终端20提出的QoS需求对该用户终端20进行分流接入控制。 On the other hand, since the access network in the network environment is constantly changing, and therefore, each of the access network in the network environment information CRRM need its own home access network in accordance with a set period, and send it to other access network, so that each can timely CRRM network environment information of each access network, so that the access control status of the entire network of distributed heterogeneous communications system to the user terminal 20 in conjunction with QoS requirements proposed to the user 20 shunting terminal access control. 基于上述两个实施例,用户终端20获得最终下发的业务分流策略后,将业务流分割成多个业务子流,并加上不同的标签,例如,本实施例中,业务流r Based on the above two embodiments, the user terminal 20 to obtain a final shunt strategy issued service, the service is divided into a plurality of sub-stream traffic flows, plus different labels, for example, in the present embodiment, traffic flow r

被分割成两个业务子流,分别为:^i必',7112^,……与7121,^,7122,2,2,……,两个业务子流的QoS需求分别为込i与込2,接着,用户终端20分别与接入网1和接入网2建立连接,并将分割好的两个业务子流分别通过接入网l和接入网2进行传输。 Traffic is divided into two sub-streams, namely: i ^ will ', 7112 ^, ...... and 7121, ^, 7122,2,2, ......, QoS traffic needs two sub-flows and includes the postage respectively includes the postage i 2, then the user terminal 20, respectively, with the access network and the access network 1 2 to establish a connection, and the two split good service sub-flows l respectively through the access network and the access network 2 for transmission. 在分布式异构通信系统的网络结构下,若下发的业务分流策略指示将有多个业务子流通过同一^姿入网络传输,则该接入网络中的CRRM将上述多个业务子流合并后再进行传输,例如, 一个业务流被用户终端20分成三个业务子流, 分别为:r。 Distributed heterogeneous network structure in a communication system, if the issued service shunt strategy indicating a plurality of traffic streams over the same sub-network transmission into ^ pose, the access network traffic CRRM the plurality of sub-streams and then combined for transmission, e.g., a user terminal traffic stream 20 is divided into three sub-flow traffic, respectively: r. ^与7;,其中,CRRM l下发的业务分流策略指示:r,通过接入网l传输,r,与7;通过接入2传输;则在分流执行阶段,CRRM2需要将7^与7;合并成一条业务流进行传输。 7 ^ ;, and wherein delivered by the CRRM policy indicates service shunt l: r, l transmission through the access network, r, and 7; 2 by access transmission; shunt at the implementation stage, CRRM2 necessary and 7 ^ 7 ; combined into a traffic stream for transmission.

本发明实施例中,用户终端20默认的接入网1中的无线资源管理装置21, 在接收到该用户终端20发送的至少携带业务类型信息的业务请求信息时,若根据业务类型信息确定需要对用户终端20进行分流接入控制,则获取接入网1 网络环境信息和至少一个与第一接入网络采用不同无线制式的第二接入网络的网络环境信息,以及获取与业务类型信息相匹配的分流建议信息,并根据获得的分流建议信息、结合接入网1和接入网2的网络环境信息生成分流策略。 Radio resource management apparatus of this embodiment, the default user 20 the access network terminal 1 of the embodiment of the present invention 21, upon receiving a user carrying the terminal 20 sends the service type information of at least a service request information according to the service type information is determined if the required the user terminal access control shunt 20, the environment information acquiring an access network environment information and at least one network using different wireless standard with a first access network of a second access network, and obtaining the service type information phase matching shunt advice information, advice information and in accordance with the obtained split, combined access network and the access network 1 2 network environment information generated offload policy. 这样,这样,在不存在共同无线资源管理实体的分布式异构通信系统中,也能以有效的方式生成业务分流策略,从而实现业务分流,以提高通信系统的服务质量,进而更大程度地满足了用户的QoS需求,提升了用户体验。 In this way, this way, the common radio resource management entity does not exist distributed heterogeneous communication systems, it can also generate service shunt strategy in an efficient manner to achieve business diversion, to improve service quality communication system, and thus a greater degree meet the QoS requirements of users, enhance the user experience.
