Description

一种基于DUA协议的消息传输方法和装置 A method and apparatus for message transmission protocol based DUA

技术领域 FIELD

[0001] 本发明涉及网络通讯技术领域,具体涉及一种基于DUA协议的消息传输方法和装置。 [0001] The present invention relates to network communication technologies, and particularly relates to a method and apparatus for message transmission protocol based DUA.

背景技术 Background technique

[0002] NGN是下一代网络系统的简称,NGN正在逐渐替代目前传统的PSTN (公共电话交换网)。 [0002] NGN is referred to as the next generation network systems, NGN is gradually replacing the current traditional PSTN (public switched telephone network). NGN和传统的PSTN网络相比,其最大的不同是控制系统/承载网络的分离,以及语音的IP化。 NGN and conventional PSTN networks compared to the biggest difference is that the control system / network separate bearer, and the IP-based speech.

[0003] 在下一代网络中,提出了“媒体网关控制器”以及“媒体网关”的概念,原有的PSTN 信令移至NGN中运行时,层间协议将分离运行于不同的网络部件,为达成此目的,引入了SIGTRAN (信令传输)信令。 When [0003] In the next generation network, the concept of "MGC" and "Media Gateway", the original PSTN signaling moved NGN run, interlayer separation protocols running on different network elements, to achieve this purpose, the introduction of the SIGTRAN (signaling transport) signaling.

[0004] SIGTRAN信令由IETF成立的一个专门的SIGTRAN工作组制定。 [0004] SIGTRAN signaling established by the IETF SIGTRAN a special working group to develop. SIGTRAN信令由一组基本功能类似的协议族组成,其目的是为保证传统电路交换信令在IP网上的可靠传输。 SIGTRAN signaling protocol family consists of a set of similar basic functions, its purpose is to ensure reliable transmission of conventional circuit-switched signaling in the IP network. DUA (DPNSS/DASS用户适配层协议)是SIGTRAN协议族中的一种。 DUA (DPNSS / DASS user adaptation layer protocol) is a SIGTRAN protocol suite.

[0005] DPNSS 1(数字私有网络信令系统)和DASS 2(数字接入信令系统)是目前BT(英国电信)网络上广泛应用的一种私网信令系统。 [0005] DPNSS 1 (Digital Private Network Signaling System) and a DASS 2 (Digital Access Signaling System) is a private network signaling system currently on BT (British Telecommunications) network widely. 为实现DPNSS1/DASS 2的层间信令迁移至NGN上运行,其2/3层协议需要分离运行于“媒体网关”以及“媒体网关控制器”设备上,如DPNSS L3或DASS 2 L3协议需要运行于“媒体网关控制器”设备,DPNSS L2或DASS 2 L2协议需要运行于“媒体网关”设备。 To achieve DPNSS1 / DASS 2 signaling interlayer migration to the NGN operation, the need for a separate layer 2/3 protocol run on "Media Gateway" and "media gateway controller" device, such as a DASS 2 L3 or DPNSS L3 protocol requires running "media gateway controller" device, DPNSS L2 or DASS 2 L2 protocols to run in "media gateway" device. 这时,需引入DUA协议实现DPNSS L3/L2层协议的互通。 In this case, it should be introduced DUA protocol interworking DPNSS L3 / L2 protocol layer.

[0006] DPNSS 1协议在NGN上的运行情况如附图1所示。 Operation [0006] DPNSS 1 protocol on the NGN as shown in Figure 1.

[0007]]图1中,PBX为私网中的小交换机设备,其信令通过SG (信令网关)设备接入NGN 网络,接受MGC(媒体网关控制器)设备的控制。 In [0007]] FIG 1, PBX is a small private network switch device, which is controlled by a signaling SG (Signaling Gateway) NGN network access device, receiving MGC (Media Gateway Controller) device. PBX和SG设备互通的物理媒介为El或Tl 接口。 SG and physical media PBX interworking device is Tl or El interface. DASS 2协议在NGN上的运行情况与上述DPNSSl协议在NGN上的运行情况类似。 DASS 2 protocol operation on the NGN with the above-described operation of the protocol on the NGN DPNSSl like.

[0008] 在实际应用中,相同的一套设备上可能需同时运行DPNSS 1和DASS 2协议,而且需通过相同的DUA协议承载,如在上面的图1中,DPNSS 1和DASS 2协议需同时承载在SG 设备和MGC设备间相同的DUA协议上。 [0008] In practice, you may need to run simultaneously on the same set of equipment and DASS 2 protocol DPNSS 1, and to be carried by the same DUA agreement, 1, DPNSS 1 and DASS 2 protocols to simultaneously as shown above carried on the same apparatus between the SG and MGC device DUA protocol.

[0009] 目前,在同一套设备上同时运行DPNSS 1和DASS 2协议的方法为:通过不同的E1/T1接口分别运行DPNSS 1和DASS 2,即一个E1/T1接口只能传输一种协议的消息,这样,如果同一套设备上需要同时运行DPNSS 1和DASS 2协议,则需要占用两个E1/T1接口, 浪费了宝贵的E1/T1资源,提高了系统的组网成本。 [0009] Currently, the method of operating a DASS 2 protocol DPNSS 1 and simultaneously on the same set of equipment as follows: Run DPNSS 1 and DASS 2 respectively different E1 / T1 interface, i.e., an E1 / T1 interface can only transmit one protocol message, so that if the same set of equipment need to run and DASS 2 protocol DPNSS 1, the need to occupy two E1 / T1 interface, wasting valuable E1 / T1 resources, increases the cost of the system network.

具体实施方式 detailed description

[0039] 在实际的组网应用中,同一套设备上会同时运行DPNSS 1和DASS 2协议,而且需要通过相同的DUA协议承载,如DPNSS 1和DASS 2协议同时承载在SG设备和MGC设备间相同的DUA协议上等。 [0039] In an actual networking application, the same set of equipment will run and DASS 2 protocol DPNSS 1, but also carried by the same DUA protocols, such as protocol DPNSS 1 and DASS 2 while carrying the device between the SG and MGC equipment DUA same protocol finest. 如果在同一套DUA协议以及相同的E1或T1线路上能够同时承载DPNSS 1协议和DASS 2协议,且接收端能够准确的区分出其接收的消息是DPNSS 1协议的消息、还是DASS 2协议的消息,接收端就能够对其从同一接口接收的不同信令协议的消息进行相应协议的处理,从而能够有效节省网络设备的接口资源,降低系统组网成本。 Message if the same set DUA protocol and the same E1 or T1 line can simultaneously carry DPNSS 1 protocol and the DASS 2 protocol, and the receiver can accurately distinguish the messages it receives that message DPNSS 1 protocol, or DASS 2 protocol , the receiving end can be processed from their respective different signaling protocols of the same protocol message received by the interface, thereby saving interface resources of the network device, network system to reduce cost.

[0040] 因此,本发明的核心是:设置不同信令系统协议分别对应的协议标识信息,发送端将需要传输的消息及该消息对应的协议标识信息传输至接收端,所述接收端根据其接收的协议标识信息确定其接收的消息对应的信令系统协议。 [0040] Thus, the core of the present invention is: a message protocol systems provided respectively corresponding to different signaling protocol identification information, the transmitting end will be transmitted and transmission of the message protocol identifier information corresponding to the receiving end, the receiving end according to their determining the protocol identification information of the received signaling system protocol messages that it receives the corresponding.

[0041] 下面基于本发明的核心思想对本发明提供的技术方案做进一步的描述。 [0041] The following further description is based on the technical solution of the present invention, the core idea of ​​the present invention is provided.

[0042] 当DUA需要在发送端和接收端之间通过同一接口资源透传DPNSS 1和DASS 2协议的消息,如在SG和MGC设备间的同一接口资源透传DPNSS 1和DASS 2协议的消息时,接收端DUA协议实体需要识别其当前接收的消息是DPNSS 1协议的消息还是DASS 2协议的消息,并在确定消息的信令协议后,需要将该消息送往对应的信令协议进行处理。 [0042] When 2 DUA required resources through the same interface protocol DPNSS 1 and DASS transparent transmission between the transmission and receiving ends of a message, the same as in the DPNSS interface resources transparently transmitted between the device 1 and the SG and MGC DASS 2 message protocol when the receiving end DUA protocol entity needs to identify its current received message is a message protocol DPNSS 1 or DASS 2 message protocol and the signaling protocol message is determined, the need for a message to be processed corresponding to the signaling protocol .

[0043] 由于DUA协议本身没有相应的“协议标识位”,如果接收端需要识别出其从同一接口资源接收的消息是DPNSS 1协议的消息还是DASS 2协议的消息,发送端就需要将其发送的消息对应的协议标识信息传输至接收端。 [0043] Since the DUA protocol itself is not appropriate "protocol identifier bit", if the receiving terminal needs to identify the message it receives from the same interface resource is a message DPNSS 1 protocol or DASS 2 protocol message, the sender needs to send protocol message corresponding to the identification information transmitted to the receiving end.

[0044] 发送端传输协议标识信息的方法很灵活,如可以采用将消息和该消息对应的协议标识信息分别传输的方法,也可以采用将消息和该消息对应的协议标识信息一起传输的方法,即将协议标识信息承载于需要传输的消息中传输至接收端的方法。 [0044] A method for transmitting end of the transmission protocol identification information is very flexible, as a method protocol identification information of the message and the message corresponding to each transmission may be employed, the method which is transmitted together with the protocol identification information of the message and the message corresponding may also be used, soon protocol identification information is carried in the message to be transmitted to the transmission method of the receiver.

[0045] 下面以协议标识信息和消息一起传输为例,对本发明提供的两种具体的实现方法进行详细说明。 [0045] In the following an example protocol identification information transmitted together with a message and, two specific implementations of the present invention provides a method will be described in detail.

[0046] 方法一:接收端利用接口标识符来区分其接收的消息是DPNSS 1协议的消息还是DASS 2协议的消息。 [0046] Method a: using the interface identifier of the receiving end to distinguish between receiving message is a message protocol DPNSS 1 or DASS 2 message protocol. 其具体实现方法为: The specific implementation method:

[0047] 首先,需要在接收端和发送端设置接口、接口标识符与DPNSS 1协议、DASS2协议的对应关系,这里的接口包括:E1接口和T1接口。 [0047] First, to set the interface, the interface protocol DPNSS 1 identifier, the correspondence relationship DASS2 protocol at the receiving end and sending end, where the interface comprises: E1 interface and a T1 interface. 接口标识符和DPNSS 1协议标识信息以及DASS 2协议标识信息的对应关系不由DUA协议保存,其对应关系需保存在具体的应用中。 DPNSS 1 and the interface identifier and the correspondence between the identification information of the protocol help DUA protocol DASS 2 protocol identification information stored, the corresponding relationship is stored for an application in particular.

[0048] 由于本发明需要区分的协议消息为:DPNSS 1协议的消息、DASS 2协议的消息,因 [0048] Since the present invention requires the protocol message is distinguished: Message protocol DPNSS 1 message, DASS 2 protocol, because

5此,可设置一个接口对应两个接口标识符,一个接口标识符对应一种信令系统协议。 5 this can be provided corresponding to the two interfaces one interface identifier, interface identifier corresponding to one kind of a signaling system protocol. “接口标识符”是DUA协议本身设置的,原本用于识别不同的E1/T1线路,本发明又赋予接口标识符一个新的含义,即本发明为相同的E1/T1线路接口定义不同的“接口标识符”,各接口标识符分别对应DPNSS 1协议和DASS 2协议。 "Interface identifier" DUA protocol itself is arranged, originally used to identify the different E1 / T1 lines, the present invention also gives a new interface identifier meaning, i.e. the present invention is the same as E1 / T1 lines different interface definitions " the interface identifier ", each corresponding interface identifier and a protocol DPNSS 1 DASS 2 protocol.

[0049] 如在附图2中,定义“接口标识符,,m对应DPNSS 1协议、η对应DASS 2协议,但m 和η均对应相同的Ε1/Τ1接口。这样,当DUA协议实体收到不同的“接口标识符”上报的消息时,即可根据接口标识符识别当前上报的消息为DPNSS 1协议的消息还是DASS 2协议的消息,如当DUA协议实体收到“接口标识符”m上报的消息时,DUA协议实体即可识别该消息为DPNSS 1消息,并将该消息上报至DPNSS 1协议进行相应的处理;当DUA协议实体收到“接口标识符”η上报的消息时,DUA协议实体即可识别该消息为DASS 2消息,并将该消息上报至DASS 2协议进行相应的处理。 [0049] As in Figure 2, the definition of "corresponding to the interface identifier m ,, protocol DPNSS 1, DASS 2 protocol corresponding to [eta], and [eta] m but both correspond to the same Ε1 / Τ1 interfaces. Thus, when the received protocol entity DUA when different "interface identifier" report message, according to the interface identifier identifying the current message is reported protocol DPNSS 1 DASS 2 message or a protocol message, such as when the DUA protocol entity receives "interface identifier" m reporting when the message, DUA protocol entity can identify the message as a message DPNSS 1, and reports the message to a protocol DPNSS 1 performs corresponding processing; when DUA protocol entity receives "interface identifier" message reported by [eta], DUA protocol entity may identify the message as a DASS 2 message, and reports the DASS 2 message to the appropriate treatment protocol.

[0050] 方法一需要接收端和发送端对接的两端设备如SG和MGC设备事先协商好接口标识符与不同信令协议的对应关系,而且,接收端和发送端的设备需要同时保存“接口标识符”和DPNSS 1协议、DASS 2协议的对应关系。 [0050] The method requires equipment at both ends abutting transmitting end and a receiving end of such equipment prior consultations SG and MGC good correspondence relationship between different signaling protocols and interface identifier, and the receiving side and the transmitting side apparatus needs while preserving the "interface identifier Fu "and protocol DPNSS 1, the correspondence relationship DASS 2 protocol. 如果一端设备不按照此方法实现,可能会给对接带来问题。 If one end of the device is not implemented in this method, it might give the docking cause problems.

[0051 ] 方法二:DUA协议在DUA公共消息头中增加协议标识信息,接收端利用该协议标识信息来识别其接收的消息是DPNSS 1协议的消息还是DASS 2协议的消息。 [0051] Method II: DUA protocol adds protocol identification information DUA common message header, the receiving end by using the identification information to identify the protocol message which is received protocol DPNSS 1 DASS 2 message or a protocol message. 其具体实现方法为: [0052] 在DUA协议中增加“协议标识信息”位,该协议标识信息位用于识别DUA协议当前发送或接收的消息为DPNSS 1协议的消息还是DASS 2协议的消息。 The specific implementation method: [0052] Added "protocol identification information" bits DUA protocol, the protocol identification information identifying bits for the message protocol DUA is currently sent or received message or a protocol DPNSS 1 2 protocol message DASS. DUA协议中的“协议标识”位可利用DUA公共消息头中原有的相关保留位或空闲位。 DUA agreement "protocol identifier" bit may utilize any original DUA common message header associated reserved bit or an idle position.

[0053] DUA的公共消息头如附图3所示,其中,DLCI字段的结构定义如附图4所示,从图4可知,DLCI字段中第0个字节的前7比特位为保留位。 [0053] DUA common message header as shown in Figure 3, wherein the structure defines DLCI field as illustrated in Figure 4, it can be seen from Figure 4, the first 7-bit DLCI field of byte 0 bit is reserved . 这些保留位中任何一位或多位均可用做“协议标识信息”位。 These reserved bits in any one or more can be used as a "protocol identification information" bits.

[0054] 如设定DLCI字段中第0比特位为“0”时,标识当前承载的是DPNSS 1协议的消息,DLCI字段中第0比特位为“1”时,标识当前承载的是DASS 2协议的消息,那么,当DUA 协议实体收到同一接口上报的消息时,即可根据DLCI字段中第0比特位识别当前上报的消息为DPNSS 1协议的消息还是DASS 2协议的消息,即当DUA协议实体收到DLCI字段中第0比特位为“0”的消息时,DUA协议实体即可识别该消息为DPNSS 1消息,并将该消息上报至DPNSS 1协议进行相应的处理;当DUA协议实体收到DLCI字段中第0比特位为“1”的消息时,DUA协议实体即可识别该消息为DASS 2消息,并将该消息上报至DASS 2协议进行相应的处理。 [0054] When the DLCI field is set as 0 bits are "0", the carrier is a message identifying the current protocol DPNSS 1, DLCI field 0th bit is "1", the current bearer is identified DASS 2 message protocol, then, when the DUA protocol entity receives a message reported by the same interface, according to DLCI field identifying the 0th bit of the current message is a message reporting protocol DPNSS 1 or DASS 2 message protocol, i.e. when DUA when the protocol entity receives the DLCI field 0th bit is "0," the message, to identify the protocol entity DUA message DPNSS 1 message and reports the message to a protocol DPNSS 1 performs corresponding processing; protocol entity when the DUA when the received DLCI field 0 of the message bits are "1", the DUA protocol entity can identify the message as a DASS 2 message, and reports the DASS 2 message to the appropriate treatment protocol. 这个例子是将第0比特位作为协议标识信息来描述的,将其它一位或多位保留位作为协议标识信息来实现消息传输的方法与上述描述基本相同,在此不再详细描述。 This example is the first 0 bit protocol identification information as described above is substantially the same as a method described in the protocol identification information to implement message transmission to another one or more reserved bits, which will not be described in detail.

[0055] 本发明中的接收端和发送端可以为:信令网关侧的DPNSS 1L2协议实体或DASS 2L2协议实体或媒体网关控制器侧的DPNSS 1L3协议实体或DASS 2L3协议实体。 [0055] In the present invention, the transmitting end and the receiving end may be: DPNSS 1L2 side signaling gateway protocol entity or entities DASS DPNSS 2L2 protocol or the media gateway controller side DASS 2L3 or 1L3 protocol entity protocol entity.
