在多制式无线网络中实现分路传输的方法、装置及系统Method, device and system for realizing branch transmission in multi-standard wireless network

技术领域technical field

本发明涉及无线通信技术，尤其涉及在多制式无线网络中实现分路传输的方法、装置及系统。 The invention relates to wireless communication technology, in particular to a method, device and system for realizing branch transmission in a multi-standard wireless network. the

背景技术Background technique

长期网络演进LTE(Long Term Evolution)是3G网络演进技术，是3G以后的无线接入网络技术。LTE网络在接入网侧只有一个节点，即eNodeB(EvolvedNodeB)，空中接口的物理PHY层、MAC层终止于此，具有自动重传ARQ、混合自动重传HARQ、无线资源管理RRM、无线资源控制RRC等功能实体。核心网侧(简称aGW-接入网关)包括移动管理实体MME、用户面实体UPE。 Long Term Evolution (LTE) is a 3G network evolution technology and a wireless access network technology after 3G. The LTE network has only one node on the access network side, that is, eNodeB (EvolvedNodeB). The physical PHY layer and MAC layer of the air interface terminate here, and it has automatic repeat transmission ARQ, hybrid automatic repeat transmission HARQ, radio resource management RRM, radio resource control Functional entities such as RRC. The core network side (aGW-access gateway for short) includes a mobility management entity MME and a user plane entity UPE. the

世界微波接入互操作性WiMAX是基于802.16的一种无线接入网络技术，基于802.16的WiMAX网络模型如图1所示，包括用户终端、接入业务网络ASN和连接业务网络CSN三个逻辑实体。其中，ASN管理IEEE 802.16空中接口，为WiMAX用户提供无线接入；ASN至少由一个基站BS和一个ASN网关(GW)组成，一个ASN可以包含单个ASN-GW或多个ASN-GW。ASN的参考模型如图2和图3所示。在图3中，一个BS逻辑上连接到一个或多个ASN-GW。 World Microwave Access Interoperability WiMAX is a wireless access network technology based on 802.16. The WiMAX network model based on 802.16 is shown in Figure 1, including three logical entities: user terminal, access service network ASN and connection service network CSN . Among them, the ASN manages the IEEE 802.16 air interface and provides wireless access for WiMAX users; the ASN consists of at least one base station BS and one ASN gateway (GW), and an ASN can include a single ASN-GW or multiple ASN-GWs. The reference model of ASN is shown in Figure 2 and Figure 3. In Figure 3, a BS is logically connected to one or more ASN-GWs. the

目前GSM系统采用时分复用TDM传输，只提供语音业务。虽然传输性能好(时延低)，还可提供时钟信号供基站使用，但对运营商而言，往往是租用E1线路，其成本非常较高。 At present, the GSM system adopts time-division multiplexing TDM transmission and only provides voice services. Although the transmission performance is good (low time delay), clock signals can also be provided for use by base stations, but for operators, E1 lines are often leased, and the cost is very high. the

考虑到未来市场对数据业务的需求，很大可能采用多制式接入网络。多制式接入网络是指多种无线接入制式(技术)统一在同一网元(主要指基站)上实现，不同无疑接入制式合用一部分设备(比如天线、射频板等)，只将各种无线接入制式中必须单独处理的部分分离出来(比如基带处理部分)。这样的优点是，运营商在增加多种服务业务的同时又能尽量节约成本。 Taking into account the future market demand for data services, it is very likely to use multi-standard access networks. Multi-standard access network means that multiple wireless access systems (technologies) are unified on the same network element (mainly referring to the base station). Different access systems undoubtedly share some equipment (such as antennas, radio frequency boards, etc.), and only the various The part that must be processed separately in the wireless access system is separated (such as the baseband processing part). The advantage of this is that the operator can save costs as much as possible while adding multiple service businesses. the

实现多制式基站时，极有可能是在GSM基础上增加其它无线接入技术，比如：在GSM基础上增加WiMAX和/或LTE等。在这种场景下，除了信令和高时延要求的业务外，其他业务数据没有必要使用高性能的E1，极可能会采用公网IP传输，因为这样性价比非常高。这时意味着多制式接入网很可能存在分路传输的情况。 When implementing a multi-standard base station, it is very likely to add other wireless access technologies on the basis of GSM, such as adding WiMAX and/or LTE to the basis of GSM. In this scenario, except for signaling and services with high latency requirements, there is no need to use high-performance E1 for other service data, and it is very likely to use public network IP for transmission, because it is very cost-effective. This means that the multi-standard access network is likely to have split transmission. the

目前的多制式接入只是针对不同空中接口传输技术如何融合以及如何统一调配空中接口资源等，业界提出的分路传输是针对支持单一接入制式的基站而言，如NodeB有两个接口：一个接口通过ATM/E1传送数据，另一个接口通过IP/FE(快速以太网)传送数据，最终在无线网络控制器进行合并处理。这种方案不仅对不同提供商的设备联互通造成障碍，而且也没有考虑在多制式下如何处理新遇到的问题：比如LTE只有两层节点(eNodeB和aGW)，如何对应到GSM的三层点等问题。 The current multi-mode access is only aimed at how to integrate different air interface transmission technologies and how to uniformly allocate air interface resources. The branch transmission proposed by the industry is aimed at base stations that support a single access system. For example, NodeB has two interfaces: one The interface transmits data through ATM/E1, the other interface transmits data through IP/FE (Fast Ethernet), and finally merges and processes in the wireless network controller. This solution not only creates obstacles to the interoperability of equipment from different providers, but also does not consider how to deal with new problems encountered under multi-standards: for example, LTE has only two layers of nodes (eNodeB and aGW), how to correspond to the third layer of GSM point and so on. the

因此，在一个基站上实现多制式(共站址下)时，需要提供新方案来有效的优化配置和利用网络侧地面传输资源。 Therefore, when implementing multiple systems (under the same site) on one base station, it is necessary to provide a new solution to effectively optimize the allocation and utilization of ground transmission resources on the network side. the

The implementation of branch transmission will be described below by taking the addition of LTE access network technology or WiMAX access technology based on the existing GSM network or UMTS network as an example. For ease of description, the "base station" referred to below refers to the BTS of GSM or the NodeB of UMTS, the "base station controller" refers to the BSC of GSM or the RNC of UMTS; the core network CN refers to the core network of GSM or UMTS. Time-division multiplexing TDM refers to a time-division multiplexing transmission system, and the transmission system can provide clock signals to network elements. the

在GSM网络基础上增加LTE接入网络技术的一种网络结构的实例如图4所示。该实例中的网络系统包括多模基站40、GSM的基站控制器41、GSM的核心网络CN42和接入网关aGW44。多模基站40通过TDM传输网络43(即E1物理介质)连接到基站控制器41，以及通过IP传输网络45连接到接入网关aGW44；基站控制器41分别与核心网络42和接入网关44连接。多模基站40具有GSM的BTS400和LTE的eNodeB401，BTS400负责接入GSM用户设备，eNodeB401负责接入LTE用户设备。 An example of a network structure in which LTE access network technology is added on the basis of the GSM network is shown in FIG. 4 . The network system in this example includes a multi-mode base station 40, a GSM base station controller 41, a GSM core network CN42 and an access gateway aGW44. The multi-mode base station 40 is connected to the base station controller 41 through the TDM transmission network 43 (ie E1 physical medium), and connected to the access gateway aGW44 through the IP transmission network 45; the base station controller 41 is connected to the core network 42 and the access gateway 44 respectively . The multi-mode base station 40 has a GSM BTS400 and an LTE eNodeB401, the BTS400 is responsible for accessing the GSM user equipment, and the eNodeB401 is responsible for accessing the LTE user equipment. the

在图4所示的网络系统中，由多模基站40和接入网关44进行数据的分路和合路处理。其中，基站40根据接入制式和/或业务属性，对上行数据进行分路处理，即选择TDM传输网43或IP传输网络45转发上行数据，对下行数据进行合路处理，即将从TDM网络43和IP传输网络45传送来的LTE数据合路后发送给用户设备。接入网关44将从TDM网络43和IP传输网络45传送来的LTE数据合路后发送给网络侧其他节点，根据LTE业务数据的属性，选择TDM传输网络43或IP传输网络45向基站40发送数据。 In the network system shown in FIG. 4 , the multi-mode base station 40 and the access gateway 44 perform splitting and combining processing of data. Among them, the base station 40 performs branching processing on the uplink data according to the access system and/or service attributes, that is, selects the TDM transmission network 43 or the IP transmission network 45 to forward the uplink data, and performs combined processing on the downlink data. It is combined with the LTE data transmitted by the IP transmission network 45 and then sent to the user equipment. The access gateway 44 combines the LTE data transmitted from the TDM network 43 and the IP transmission network 45 and sends them to other nodes on the network side, and selects the TDM transmission network 43 or the IP transmission network 45 to send to the base station 40 according to the attributes of the LTE service data. data. the

GSM与LTE之间可以统一优化配置部分传输资源其中，基站控制器41与核心网42和接入网关44之间可以统一管理和配置传输资源。如，在GSM的TDM传输时隙空闲时，可以将其部分调节给LTE使用，即在这些时隙上承载IP数据包。在该网络系统中，多模基站40与接入网关44之间传送LTE网络的数据时，根据业务属性选择TDM传输网络43或者选择IP传输网络45。对于LTE信令，优先选择TDM传输网络43，对于高优先级和/或高服务质量QoS要求的LTE网络的业务，优先选择TDM传输网络43传送该业务的数据，典型地，如语音业务、流媒体业务等；对LTE网络的其他业务(如，低优先级和 /或QoS要求低的业务)，选择IP传输网络45传送其业务数据，如，邮件业务等。一般情况下，对于GSM的业务数据，优先选择TDM传输网络43传送，当然，对于优先级低和/或QoS要求低的GSM业务，也可以通过IP网络传送，此时，可以采用TDM over IP的方式，将TDM数据承载到IP传输网络45上，如GSM中的邮件业务，短消息业务等。 Some transmission resources can be uniformly optimized and configured between GSM and LTE. Among them, transmission resources can be uniformly managed and configured between the base station controller 41 , the core network 42 and the access gateway 44 . For example, when the TDM transmission time slots of GSM are idle, some of them can be adjusted for use by LTE, that is, IP data packets are carried on these time slots. In this network system, when data of the LTE network is transmitted between the multi-mode base station 40 and the access gateway 44, the TDM transmission network 43 or the IP transmission network 45 is selected according to service attributes. For LTE signaling, the TDM transmission network 43 is preferentially selected, and for LTE network services with high priority and/or high service quality QoS requirements, the TDM transmission network 43 is preferentially selected to transmit the data of the service, typically, such as voice services, streaming Media business etc.; To other business of LTE network (as, the business of low priority and/or QoS requirement), select IP transmission network 45 to transmit its service data, as, mail service etc. Generally, for GSM business data, the TDM transmission network 43 is preferred for transmission. Of course, for GSM services with low priority and/or low QoS requirements, they can also be transmitted through the IP network. At this time, TDM over IP can be used. In this way, the TDM data is carried on the IP transmission network 45, such as mail service and short message service in GSM. the

在图4所示的网络系统中，虽然eNodeB401和接入网关44之间的分传输线路需要经过基站控制器41，但并不需要基站控制器41解析其上层的信息内容，只需要在基站控制器41与其它制式的传输资源一起在物理层，最多在数据链路层或者IP层做一些复用/解复用、交换或者路由的处理工作即可。 In the network system shown in Figure 4, although the sub-transmission line between the eNodeB 401 and the access gateway 44 needs to pass through the base station controller 41, it does not need the base station The device 41, together with transmission resources of other standards, can be at the physical layer, and at most can perform some processing work of multiplexing/demultiplexing, switching or routing at the data link layer or IP layer. the

在图4所示网络系统中，处理上行数据的一个实例如图5A所示： In the network system shown in Figure 4, an example of processing uplink data is shown in Figure 5A:

步骤500、多模基站40接收GSM用户设备和LTE用户设备向网络侧发送的数据。多模基站40可能同时接收到不同用户的数据，也可能同时接收到多个用户的数据。 Step 500, the multi-mode base station 40 receives data sent by the GSM user equipment and the LTE user equipment to the network side.

上述流程中多模基站40的判断分析仅是一个具体实例，在具体实现中，多模基站40对数据的分析可以有不同的策略，如先区分信令和业务数据，然后再进一步区分业务数据的优先级及QoS等属性信息，其中处理过程与上述同理，不再赘述。 The judgment and analysis of the multi-mode base station 40 in the above process is only a specific example. In a specific implementation, the multi-mode base station 40 can have different strategies for data analysis, such as distinguishing signaling and service data first, and then further distinguishing service data Attribute information such as priority and QoS, etc., the processing process is the same as above, and will not be repeated here. the

The BTS700 is responsible for accessing the GSM user equipment, and the access service network is responsible for accessing the WiMAX user equipment. the

在图7所示的网络系统中，由多模基站70和连接业务网络74进行数据的分路和合路处理。其中，多模基站70根据接入制式和/或业务属性，对上行数据进行分路处理，即选择TDM传输网73或IP传输网络75转发上行数据，对下行数据进行合路处理，即将从TDM网络73和IP传输网络75传送来的WiMAX网络的数据合路后发送给WiMAX系统的用户设备。连接业务网络74 将从TDM网络73和IP传输网络75传送来的WiMAX网络的数据合路后发送给网络侧其他节点，根据WiMAX业务数据的属性，选择TDM传输网络73或IP传输网络75向多模基站70发送数据。 In the network system shown in FIG. 7 , the multi-mode base station 70 and the connection service network 74 perform splitting and combining processing of data. Among them, the multi-mode base station 70 splits the uplink data according to the access system and/or service attributes, that is, selects the TDM transmission network 73 or the IP transmission network 75 to forward the uplink data, and performs combination processing on the downlink data. The data of the WiMAX network transmitted by the network 73 and the IP transmission network 75 are combined and sent to the user equipment of the WiMAX system.

For the signaling of the WiMAX network, the TDM transmission network 73 is preferentially selected. For the business of the WiMAX network with high priority and/or high service quality QoS requirements, the TDM transmission network 73 is preferentially selected to transmit the data of the service, typically, such as a voice service , streaming media services, etc.; for other services of the WiMAX network (eg, services with low priority and/or low QoS requirements), select the IP transmission network 75 to transmit their service data, such as mail services, etc. Generally, for GSM service data, the TDM transmission network 73 is preferred for transmission. Of course, for GSM services with low priority and/or low QoS requirements, they can also be transmitted through the IP network. At this time, TDM over IP can be used. In this way, the TDM data is carried on the IP transmission network 75, such as mail service and short message service in GSM. the

在图7所示的网络中，对上行数据和下行数据的处理与图4所示的网络系统同理，不再赘述。 In the network shown in FIG. 7 , the processing of uplink data and downlink data is the same as that of the network system shown in FIG. 4 , which will not be repeated here. the

The network system includes a multi-mode base station 80, a GSM base station controller 81, a GSM core network CN82 and a connection service network 84 in the WiMAX system. The multi-mode base station 80 has a GSM BTS800 and a base station BS801 in the WiMAX access service network ASN, and the base station controller 81 has a gateway GW802 in the access service network ASN.

从图8与图7所示的网络系统可以看出，该网络结构与图7所示的网络结构主要区别在于，图7中所示的网络系统中，基站BS701和网关GW702均设置在多模基站70，而图8所示的网络系统中，基站BS801设置在多模基站80上，网关GW802设置在基站控制器81上。 From the network systems shown in Figure 8 and Figure 7, it can be seen that the main difference between the network structure and the network structure shown in Figure 7 is that in the network system shown in Figure 7, both the base station BS701 and the gateway GW702 are set in a multi-mode Base station 70, and in the network system shown in FIG. the

在图8所示的网络系统中，多模基站80、基站控制器81和连接业务网络84都可以采用分路传输方式。例如，对于WiMAX用户设备发送的上行数据由基站80选择TDM传输网络83或IP传输网络85传输，对于WiMAX网络的数据可以在基站控制81进行合路处理，也可以在连接业务网络84进行合路处理；对于WiMAX网络发送的下行数据，可以由连接业务网络84选择TDM传输网络83或IP传输网络85传输，也可由连接业务网络84将数据发送到基站控制81，由基站控制器81选择TDM传输网络83或IP传输网络85传输。通过TDM传输网络传送WiMAX网络的数据时，可以采用TDM over IP的方式。 In the network system shown in FIG. 8 , the multi-mode base station 80 , the base station controller 81 and the connection service network 84 can all adopt the split transmission mode. For example, the base station 80 selects the TDM transmission network 83 or the IP transmission network 85 to transmit the uplink data sent by the WiMAX user equipment, and the data of the WiMAX network can be combined in the base station control 81 or can be combined in the connection service network 84 Processing: For the downlink data sent by the WiMAX network, the connection service network 84 can select the TDM transmission network 83 or the IP transmission network 85 for transmission, or the connection service network 84 can send the data to the base station control 81, and the base station controller 81 selects TDM transmission Network 83 or IP transmission network 85 transmission. When transmitting WiMAX network data through the TDM transmission network, TDM over IP can be used. the

虽然上述以多模基站支持GSM接入和LTE接入，以及支持GSM接入和WiMAX接入为例进行说明，但并不限于此，上述描述的分路传输同样适用于多模基站支持UMTS接入和LTE接入，支持UMTS接入和WiMAX接入，以及支持GSM接入、UMTS接入、LTE接入和WiMAX接入中的三种或三种以上的组合。 Although the description above takes the multi-mode base station supporting GSM access and LTE access, and supporting GSM access and WiMAX access as an example, it is not limited to this. The branch transmission described above is also applicable to the multi-mode base station supporting UMTS access. Access and LTE access, support UMTS access and WiMAX access, and support a combination of three or more of GSM access, UMTS access, LTE access, and WiMAX access. the

图9给出了在UTMS网络基础上增加LTE接入技术的一种网络结构的实例，该组网结构与图4所示的组网结构类似。其中，多模基站90中包括具有UTMS的NodeB900和LTE的eNodeB901，NodeB900负责接入UTMS用户设备，eNodeB401负责接入LTE用户设备。与图4不同的是，多模基站90与无线网络控制器91之间，以及无线网络控制器91与核心网络92和接入网关94之间的通过ATM传输网络93连接；通过ATM传输网络93传输LTE网络的数据时，可采用IP Over ATM技术，LTE网络的信令、以及高优先级和/或高服务质量QoS要求的业务数据优先选择ATM传输网络93传输，LTE网络的其他业务数据通过IP传输网络95传输，其处理方式与图4所示的网络系统同理。 FIG. 9 shows an example of a network structure in which LTE access technology is added on the basis of the UTMS network. The network structure is similar to the network structure shown in FIG. 4 . Wherein, themulti-mode base station 90 includes NodeB900 with UTMS and eNodeB901 with LTE, NodeB900 is responsible for accessing UTMS user equipment, and eNodeB401 is responsible for accessing LTE user equipment. The difference from Fig. 4 is that between themulti-mode base station 90 and theradio network controller 91, and between theradio network controller 91 and thecore network 92 and theaccess gateway 94 are connected through theATM transmission network 93; through theATM transmission network 93 When transmitting the data of the LTE network, the IP Over ATM technology can be used, the signaling of the LTE network, and the service data required by high priority and/or high service quality QoS are preferentially selected for transmission by theATM transmission network 93, and other service data of the LTE network are transmitted through TheIP transmission network 95 transmits, and its processing method is the same as that of the network system shown in FIG. 4 . the

图10给出了在GSM和UTMS网络基础上增加LTE接入技术的一种网络结构的实例，该组网结构中多模块基站与基站控制器(包括BSC和RNC)之间通过ATM传输网络和TDM传输网络连接。由于TDM传输网络和ATM传输网络都具有较高的传输性能，因此，多模基站和基站控制器从TDM传输网络、ATM传输网络和IP传输网络中按QoS性能由高到低的顺序选择传输网络传送信令，高优先级和高QoS的业务数据。较佳的方式是，对于UTMS网络的数据主要通过ATM传输网络传输，对于GSM网络的数据主要通过TDM传输网络传输，对于LTE网络的信令，选择ATM传输网络或TDM传输网络传输。在该网络系统中对数据的分路和合路处理与前述网络系统中的处理过程同理，不再赘述。 Figure 10 shows an example of a network structure in which LTE access technology is added on the basis of GSM and UTMS networks. In this network structure, multi-module base stations and base station controllers (including BSC and RNC) are connected through ATM transmission network and TDM transport network connection. Since both the TDM transmission network and the ATM transmission network have high transmission performance, the multimode base station and the base station controller select the transmission network from the TDM transmission network, ATM transmission network and IP transmission network according to the order of QoS performance from high to low. The network transmits signaling, high priority and high QoS business data. Preferably, the data of the UTMS network is mainly transmitted through the ATM transmission network, the data of the GSM network is mainly transmitted through the TDM transmission network, and the signaling of the LTE network is transmitted through the ATM transmission network or the TDM transmission network. The splitting and combining processing of data in this network system is the same as the processing process in the aforementioned network system, and will not be repeated here. the

根据图4至图10及前述的描述，本领域的普通技术人员容易得到在GSM和UTMS网络基础上增加LTE接入技术和WiMAX接入的网络结构，在这种结构中对数据的处理与前述网络系统同理，不再赘述。 According to Fig. 4 to Fig. 10 and foregoing description, those of ordinary skill in the art can easily obtain the network structure that adds LTE access technology and WiMAX access on the basis of GSM and UTMS network, in this structure to the processing of data and aforementioned The same is true for the network system and will not be repeated here. the

图11给出了本实施例中一种分路/合路功能模块的结构示意图，主要包括第一识别模块110、选择模块111、第二识别模块112和合路模块113。其中，第一识别模块110根据接收到的数据识别不同的无线接入制式(如GSM制式和LTE制式)，识别某一无线接入制式的信令面数据和用户面数据，以及识别用户面数据的优先级和QoS等信息；选择模块111根据识别结果选择传送数据的传输网络。第二识别模块112根据从多个传输网络接入到的数据，识别不同的无线接入制式(如GSM制式和LTE制式)，识别某一无线接入制式的信令面数据和用户面数据；所述合路模块113根据识别结果将某一制式的数据合路后发送给用户设备。所述分路/合路功能模块可设置在前述的多模基站，以及具有分路和合路功能的接入网关以及连接业务网络中，甚至可以作为一个独立的实体。 FIG. 11 shows a schematic structural diagram of a branching/combining functional module in this embodiment, which mainly includes a first identification module 110 , a selection module 111 , a second identification module 112 and a combination module 113 . Among them, the first identification module 110 identifies different wireless access standards (such as GSM standard and LTE standard) according to the received data, identifies signaling plane data and user plane data of a certain wireless access standard, and identifies user plane data information such as priority and QoS; the selection module 111 selects the transmission network for transmitting data according to the identification result. The second identification module 112 identifies different wireless access standards (such as GSM standard and LTE standard) according to data accessed from multiple transmission networks, and identifies signaling plane data and user plane data of a certain wireless access standard; The combining module 113 combines the data of a certain standard and sends it to the user equipment according to the identification result. The splitting/combining functional module can be set in the aforementioned multi-mode base station, access gateway with splitting and combining functions, and a connection service network, and can even be used as an independent entity. the

上述虽然以多模基站与其上层节点之间传送数据为例进行说明，但本实施例中的方法同样适用于两个多模基站之间传送数据，因为两个基站之间同样可能存在多个传输网络。其实现方式与上述同理，不再赘述。 Although the above description takes data transmission between a multi-mode base station and its upper node as an example, the method in this embodiment is also applicable to data transmission between two multi-mode base stations, because there may also be multiple transmissions between two base stations. network. Its implementation method is the same as that described above, and will not be repeated here. the

在本实施例中，分路传输策略的实现可以有多种方式。如，按照信令面和用户面分类，让所有信令走“高性能”的传输路径，让用户面数据走其它传输路径；比如，信令面建立在与GSM的TDM传输网络或者UMTS的ATM传输网络“共享”的传输路径上；用户面则建立在“便宜的IP传输网”上。又如，按照基于业务优先级属性的准静态配置方式，在针对某个业务的传输承载建立时，根据业务优先级属性进行分析，从而决定将业务的传输承载建立在哪些传输线路上，比如，HSDPA业务走公网IP传输；语音、流媒体走TDM传输网络。再如，按实时动态配置方式，在传输过程中，依据当前传输网络的流量，动态调整传输层资源，充分利用已有“高质量”传输资源—比如：对租用的E1线路，力求达到饱和使用，但一旦有新的高优先级业务接入，能及时将时延要求低的数据业务“迁移”在另外的“便宜的”时延没有保障的传输路径上。 In this embodiment, there may be multiple ways to realize the branch transmission policy. For example, according to the classification of the signaling plane and the user plane, let all signaling take the "high-performance" transmission path, and let the user plane data take other transmission paths; for example, the signaling plane is established on the TDM transmission network with GSM or the ATM of UMTS The transmission network is "shared" on the transmission path; the user plane is built on the "cheap IP transmission network". As another example, according to the quasi-static configuration method based on the service priority attribute, when the transmission bearer for a certain service is established, it is analyzed according to the service priority attribute, so as to determine which transmission lines to establish the service transmission bearer on, for example, HSDPA The business is transmitted through the public network IP; the voice and streaming media are transmitted through the TDM transmission network. As another example, according to the real-time dynamic configuration method, during the transmission process, according to the current transmission network traffic, the transmission layer resources are dynamically adjusted to make full use of the existing "high-quality" transmission resources—for example: for the leased E1 line, strive to achieve saturation , but once a new high-priority service is accessed, the data service with low latency requirements can be "migrated" in time to another "cheap" transmission path with no guaranteed latency. the

采用本实施例描述的方法，在多制式接入网络中维持原有GSM业务、UMTS业务的基础上，能够加入LTE或者WiMAX接入技术以扩充数据业务，可以充分利用GSM、UMTS原有传输资源的优势，比如，利用TDM传输资源具有时延低、可提供时钟参考信息等特点传输信令、高时延要求的业务，再另外扩充其它传输线路(主要是利用便宜的公网IP传输)以支持市场上日益增加的数据业务。因此，采用前述方法，能够在保证业务传输质量的前提下，为运营商大幅度的降低成本。 Using the method described in this embodiment, on the basis of maintaining the original GSM service and UMTS service in the multi-standard access network, LTE or WiMAX access technology can be added to expand the data service, and the original transmission resources of GSM and UMTS can be fully utilized For example, using TDM transmission resources with low delay and providing clock reference information to transmit signaling and services with high delay requirements, and then expand other transmission lines (mainly using cheap public network IP transmission) to Support the increasing data business in the market. Therefore, by adopting the aforementioned method, the cost can be greatly reduced for the operator on the premise of ensuring the quality of service transmission. the
