技术领域 Technical field
本发明涉及网络通信技术领域, 尤其涉及一种实现信令网互通的方法 及装置。 The present invention relates to the field of network communication technologies, and in particular, to a method and apparatus for implementing signaling network interworking.
背景技术 Background technique
通常, 对于一个国家或者一个具体的电信运营商, 他们的信令网是有 明确 NI (网络标识) 的, 所述 NI为传统的 SS7 ( 7号信令***) 网络标准所 限定的网络标识, 且该标识包括: 国内主用网、 国内备用网、 国际主用网 和国际备用网四种, 反映在具体信令网上传输的信令消息上, 就是每个 MTP3 (消息转移部分) 消息头中的 SIO (业务信息八位组) 内只有一个字 节的 NI, 由于 NI只占用两个比特, 所以只能用来区分四种类型的信令网络。 Generally, for a country or a specific telecommunication operator, their signaling network has a clear NI (network identity), which is a network identifier defined by the traditional SS7 (Signaling System No. 7) network standard. And the identifier includes: a domestic primary network, a domestic backup network, an international primary network, and an international standby network, which are reflected in a signaling message transmitted on a specific signaling network, that is, in each MTP3 (message transfer part) message header. There is only one byte of NI in SIO (Business Information Octet). Since NI only occupies two bits, it can only be used to distinguish four types of signaling networks.
随着电信网络的复杂化, 部分运营商自己不必建设信令网而是通过租 用等方式应用其它运营商的信令网络, 这就使得一个信令网络可能作为共 用网络同时为多个运营商提供服务。 为了保证一个信令网络可以同时为多 个运营商服务, 并保证被服务的各个运营商之间又不相互影响, 需要在网 络之间采用一定的隔离技术。 With the complication of the telecommunication network, some operators do not need to build a signaling network themselves, but apply signaling networks of other operators through leasing, etc., which makes one signaling network possible as a shared network and simultaneously provides multiple operators. service. In order to ensure that a signaling network can serve multiple operators at the same time, and ensure that the operators that are served do not interact with each other, a certain isolation technology needs to be adopted between the networks.
然而, 由于在一个国家内, 多个运营商使用的信令网的 NI均选择为国 内主用网, 所以依靠 NI使一个信令网络同时为多个运营商提供服务的方式 无法实现(除非由一个团体全国统一分配信令点编码) , 而且还由于相应 规范的限定, 也无法针对仅有两个比特的 M进行扩展, 以满足其提供多网 络服务的需求。 However, since the NI of the signaling network used by multiple operators in a country is selected as the domestic primary network, it is impossible to rely on NI to enable one signaling network to simultaneously serve multiple operators (unless by A group uniformly allocates signaling point codes throughout the country, and because of the limitations of the corresponding specifications, it is not possible to extend M for only two bits to meet the needs of providing multiple network services.
基于上迷原因, 目前的各运营商之间的信令网络均为各自独立建设, 而且, 各个运营商的信令点编码资源可能也是自己独立进行分配, 导致多 个运营商之间很可能存在重复的信令点编码, 从而使得信令网间互通根本 无法实现, 尤其是在 MTP3层。
目前, 很多情况下各运营商的信令网分别为各自独立建设, 仅在 MTP3 的用户层实现信令互通。 即在跨网络的呼叫接续时信令消息不是在网絡之 间直接在 MTP3层进行转发, 而是在网络之间的网关设备上信令消息经过 MTP3的用户层协议处理, 然后重新发起呼叫到另一个网络。 而网络间的信 令网仍然是隔离的,这种用户层的互通很可能造成不必要的通信话路迂回。 Based on the above reasons, the signaling networks between the operators are built independently. Moreover, the signaling point coding resources of each operator may also be allocated independently, resulting in the possibility of existence among multiple operators. Repeated signaling point coding, so that interworking between signaling networks is not possible at all, especially at the MTP3 layer. At present, in many cases, the signaling networks of the operators are independently constructed, and signaling interworking is implemented only at the user layer of the MTP3. That is, when the call is connected across the network, the signaling message is not directly forwarded between the networks at the MTP3 layer, but the signaling message on the gateway device between the networks is processed by the user layer protocol of the MTP3, and then the call is re-initiated to another A network. The signaling network between the networks is still isolated, and the interworking of such user layers is likely to cause unnecessary communication paths.
为此, 网络运营需求希望实现多个运营商能够共用一个信令网, 即必 须实现 MTP3层的互通, 但是, 目前还没有相应的技术实现 MTP3层次的互 通, 也就无法实现一个信令网分别为多个运营商提供服务。 To this end, network operation requirements are expected to enable multiple operators to share a single signaling network, that is, MTP3 layer interworking must be implemented. However, there is no corresponding technology to implement MTP3 layer interworking, and thus it is impossible to implement a signaling network. Serve multiple operators.
例如, 如图 1所示, 在 SS7协议标准的范围内, 多个运营商网络都使用 同一 NI, 并且应用可能重复的信令点编码, 此时, 各个运营商网络将无法 共用同一信令网的 STP设备,尤其是在不同的运营商网络使用不同的协议标 准的情况下, 例如在图 1中: For example, as shown in Figure 1, within the scope of the SS7 protocol standard, multiple carrier networks use the same NI, and the application may repeat the signaling point coding. At this time, each carrier network cannot share the same signaling network. STP devices, especially if different carrier networks use different protocol standards, such as in Figure 1:
网络 1 : NI为 "国内主用网" ; 使用 ANSI (美国国家标准化组织)标 准的 SS7协议; 使用 14位信令点编码方式; Network 1 : NI is the "domestic primary network"; uses the ANSI (American National Standards Organization) standard SS7 protocol; uses 14-bit signaling point coding;
网络 2: NI为 "国内主用网" ; 使用 ANSI标准的 SS7协议; 使用 24位信 令点编码方式; Network 2: NI is the "domestic main network"; uses the ANSI standard SS7 protocol; uses 24-bit signaling point encoding;
网络 3: NI为 "国内主用网" ; 使用 ITU-T (国际电信联盟)标准的 SS7 协议; 使用 14位信令点编码方式; Network 3: NI is the "domestic primary network"; uses the ITU-T (International Telecommunication Union) standard SS7 protocol; uses 14-bit signaling point coding;
网络 4: NI为 "国内主用网" ; 使用 ITU-T标准的 SS7协议; 使用 24位 信令点编码方式。 Network 4: NI is the "domestic main network"; uses the ITU-T standard SS7 protocol; uses 24-bit signaling point coding.
在图 1 中, STP设备无法为上述四个网络同时提供服务。 然而, 随着 电信网络的建设, 已经出现上述组网的应用需求。 这就使得实现上述各网 络间的互通成为一个亟待解决的问题。 In Figure 1, the STP device cannot provide services for the above four networks simultaneously. However, with the construction of telecommunication networks, the application requirements of the aforementioned networking have emerged. This makes the interworking between the above networks an urgent problem to be solved.

本发明所述的方法的具体实现过程如图 3所示, 包括: The specific implementation process of the method of the present invention is shown in FIG. 3, and includes:
步骤 31 : 在 STP信令处理设备中, 将设备中的信令链路组资源数据以 及与本点相关的目的信令点数据等信令资源划分为若干組, 每组对应一个 逻辑网络; 即在信令设备中建立相应的逻辑网络, 为每个逻辑网络配置信 令链路組及目的信令点数据,及其相关的数据;这样便可以将 STP中的目的 信令点和信令链路组逻辑地分成了多组, 每组对应一个逻辑网络; Step 31: In the STP signaling processing device, the signaling resource group data in the device and the signaling resource data related to the destination signaling point data in the device are divided into several groups, and each group corresponds to one logical network; Establish a corresponding logical network in the signaling device, configure signaling link group and destination signaling point data, and related data for each logical network; thus, the destination signaling point and signaling chain in the STP can be The road group is logically divided into multiple groups, each group corresponding to one logical network;
STP设备是构成信令网的最主要设备, 其主要实现的功能是实现信令 消息的网絡层转发, 也就是在 MTP3层对消息进行转发处理; The STP device is the most important device that constitutes the signaling network. The main function of the STP device is to implement network layer forwarding of signaling messages, that is, to forward messages to the MTP3 layer.
所述的信令链路组数据及目的信令点数据即为目前信令网规定的数据 内容; 也就是说, 所述设备在配置信令链路组数据或者目的信令点数据时
配置的是逻辑网络的相应数据, 即逻辑网络可以按照信令链路组资源进行 划分, 也可以按照目的信令点资源进行划分。 The signaling link group data and the destination signaling point data are the data content specified by the current signaling network; that is, when the device configures the signaling link group data or the destination signaling point data. The corresponding data of the logical network is configured, that is, the logical network may be divided according to the signaling link group resources, or may be divided according to the destination signaling point resources.
所述信令链路组及目的信令点数据, 及其相关的数据为根据具体的规 范( ITU-T Q.704等)和具体协议实现设定, 其作用是当接收或者发送信令 消息时会根据消息内的一些信息对应到一个具体的信令链路组和目的信令 点; 所述信令链路组是连接到一个具体信令点的信令链路的集合, 信令链 路是到其它设备的实际物理连接, 经过这些数据的匹配过程才能够把信令 消息发送到正确的目的地。 The signaling link group and the destination signaling point data, and related data are set according to a specific specification (ITU-T Q.704, etc.) and a specific protocol, and the role is to receive or send a signaling message. According to some information in the message, a specific signaling link group and a destination signaling point are corresponding; the signaling link group is a set of signaling links connected to a specific signaling point, and the signaling chain The path is the actual physical connection to other devices, and the matching process of these data can send the signaling message to the correct destination.
步骤 32, 为逻辑网络分配用于通信的信令通信数据信息, 该信息包括: 逻辑网络标识、 本逻辑网络使用的本局信令点编码列表、信令点编码类型、 用于与其他逻辑网络实现互通的配置信息以及上述信息的对应关系; 在实 际应用中, 上述用于通信的信令通信数据信息中的各个项, 可以位于同一 逻辑网络配置表中, 也可以位于设备的信令链路组数据、 或目的信令点数 据中或设备中已有的其他数据中; 总之, 因为设备中的各种数据之间是存 在相互关联关系的, 因此, 只要上述用于通信的信令通信数据及对应关系 存在于设备中, 并通过各种关联能够找到即可, 具体的存在形式不做限制。 Step 32: Allocate signaling communication data information for communication to the logical network, where the information includes: a logical network identifier, a local signaling point code list used by the logical network, a signaling point coding type, and is used to implement with other logical networks. The configuration information of the interworking and the corresponding relationship of the foregoing information; in an actual application, each item in the signaling communication data information used for the communication may be located in the same logical network configuration table, or may be located in the signaling link group of the device. Data, or destination signaling point data, or other data already in the device; in summary, because there is a correlation between various data in the device, as long as the above signaling communication data for communication and Correspondence exists in the device and can be found through various associations. The specific form of existence is not limited.
逻辑网络标识: 用于标识一个逻辑网络; Logical network identifier: used to identify a logical network;
本逻辑网络使用的本局信令点编码列表: 标识本逻辑网络对应的本局 信令点编码列表, 即在设备的信令链路组数据中或者目的信令点数据中配 置一組本局信令点编码; 如果信令点编码数量大于 1 , 说明此信令设备提供 多信令点编码能力, 即一个信令设备拥有多个信令点编码, 这组本局信令 点编码也可以配置在所述的逻辑网络配置表中; The local signaling point code list used by the logical network: identifies the local signaling point code list corresponding to the logical network, that is, configures a local signaling point in the signaling link group data of the device or the destination signaling point data. Encoding; if the number of signaling point codes is greater than 1, it indicates that the signaling device provides multiple signaling point coding capabilities, that is, one signaling device has multiple signaling point codes, and the set of local signaling point codes may also be configured in the Logical network configuration table;
所述的本逻辑网络使用的本局信令点编码列表为本设备拥有的所有信 令点编码的一个子集, 对应逻辑网络中的其它设备可以以这组信令点编码 与 STP进行对接; 这样每个逻辑网絡都对应一个或者多个本局信令点编码, 如果不同逻辑网絡使用的协议标准相同, 信令点编码格式等也相同, 那么 不同逻辑网络可以对应相同的本局信令点编码, 也就是不同逻辑网络对应 的本局信令点编码列表可以出现交集; The local signaling point code list used by the logical network is a subset of all signaling point codes owned by the device, and other devices in the corresponding logical network can be connected to the STP by using the set of signaling point codes; Each logical network corresponds to one or more local signaling point codes. If different logical networks use the same protocol standard and the signaling point encoding format is the same, different logical networks may correspond to the same local signaling point code. That is, the local signaling point code list corresponding to different logical networks may have an intersection;
对于需要互通的逻辑网络,本发明所述的信令功能实体,如 STP、 SGW
等构成了核心信令网络, 这个核心信令网络可以被多个非核心信令网络共 享,这些非核心信令网络中的一些信令相关设备需要连接到核心信令网络, 但这些非核心信令网络中的信令相关设备节点上不能使用重复的信令点编 码, 以避免信令点编码的冲突, 导致无法互通; For the logical network that needs to communicate with each other, the signaling functional entities, such as STP and SGW, are described in the present invention. And so on constitute the core signaling network, this core signaling network can be shared by multiple non-core signaling networks, some of the non-core signaling networks need to be connected to the core signaling network, but these non-core letters It is not possible to use repeated signaling point coding on the signaling related device nodes in the network to avoid conflicts in signaling point coding, resulting in incompatibility;
信令点编码类型: 用于标识本逻辑网络内部信令点编码是 14位还是 24 位; 也就是说, 当设备收到信令消息后根据该信令点编码类型来解析消息 中的目的信令点编码( DPC ) ; Signaling point coding type: It is used to identify whether the internal signaling point code of the logical network is 14 bits or 24 bits; that is, when the device receives the signaling message, it resolves the destination message in the message according to the coding type of the signaling point. Order point coding ( DPC ) ;
用于与其他逻辑网络实现互通的配置信息: 用于配置不同逻辑网络之 间在 MTP3层的互通信息; Configuration information for interworking with other logical networks: Used to configure interworking information between different logical networks at the MTP3 layer;
具体可以设置一个本逻辑网络能够在 MTP3直接实现互通的其它逻辑 网络列表, 用于标识本逻辑网络能够与哪些逻辑网絡在 MTP3直接实现互 通; Specifically, a logical network list in which the logical network can directly interwork in the MTP3 can be set to identify which logical networks can directly communicate with the MTP3.
也可以通过在目的信令点数据中配置其所属的多个逻辑网络的方式实 现可以互通的逻辑网络的配置; It is also possible to implement the configuration of the logical network that can be interworked by configuring a plurality of logical networks to which the destination signaling point data belongs.
如果没有配置成互通,则不同逻辑网络之间的信令业务不能互相发送, 不同逻辑网络之间业务的相互隔离, 也就是没有配置成互通的逻辑网络之 间不能在 MTP3层互相转发消息。 If the interworking is not performed, the signaling services between different logical networks cannot be sent to each other. The services of different logical networks are isolated from each other, that is, the logical networks that are not configured to communicate with each other cannot forward messages to each other at the MTP3 layer.
基于上述配置, 信令设备对接收的消息的具体处理流程仍如图 3所示, 包括: Based on the foregoing configuration, the specific processing flow of the received message by the signaling device is still as shown in FIG. 3, including:
步骤 33: 当信令设备收到一条需要转发的信令消息时, 判断所述的消 息中的目的信令点编码是否为本局信令点编码列表中的一个, 如果是, 则 执行步驟 38, 否则, 执行步骤 34。 Step 33: When the signaling device receives a signaling message that needs to be forwarded, it is determined whether the destination signaling point code in the message is one of the local signaling point code list, and if yes, step 38 is performed. Otherwise, go to step 34.
步骤 34: 确定接收的消息中的目的信令点编码不是本局信令点编码列 表中任何一个, 则需要根据信令消息的入链路组编号或者消息的 OPC (源 信号点编码)等信息, 在本地配置的数据中查找到所述消息对应的起源网 络的逻辑网络标识; 然后, 还需要再根据消息内的 DPC (目的信号点编码) 等信息在设备配置的数据中查找到这个消息对应的目的网络的逻辑网络标 识; Step 34: Determining that the destination signaling point code in the received message is not any one of the local signaling point code list, and the information about the inbound link group number of the signaling message or the OPC (source signal point code) of the message is required. Finding the logical network identifier of the originating network corresponding to the message in the locally configured data; and then, searching for the corresponding information of the message in the data configured by the device according to the information such as DPC (destination signal point code) in the message. Logical network identifier of the destination network;
如果逻辑网络是按照信令链路组资源进行划的, 则根据入链路组编号
确定该消息对应的起源网络的逻辑网络信息; 如果逻辑网络是按照目的信 令点资源进行划分, 则根据 OPC确定该消息对应的起源网络的逻辑网络信 步骤 35: 判断两个逻辑网络标识, 即所述消息的起源网络的逻辑网络 标识和目的网络的逻辑网络标识, 是否相同, 如果相同, 则执行步骤 39, 否则, 执行步骤 36。 If the logical network is mapped according to the signaling link group resources, it is based on the inbound link group number. Determining the logical network information of the originating network corresponding to the message; if the logical network is divided according to the destination signaling point resource, determining the logical network information of the originating network corresponding to the message according to the OPC step 35: determining two logical network identifiers, ie Whether the logical network identifier of the origin network of the message and the logical network identifier of the destination network are the same. If they are the same, go to step 39. Otherwise, go to step 36.
步據 36: 如果上述的起源网络的逻辑网络标识不等于目的网络的逻辑 网络标识, 则需要根据配置信息判别这两个逻辑网络是否是互通的, 如果 是, 则执行步骤 39, 否则, 执行步骤 37。 Step 36: If the logical network identifier of the origin network is not equal to the logical network identifier of the destination network, it is determined whether the two logical networks are interworking according to the configuration information. If yes, go to step 39. Otherwise, perform steps. 37.
步驟 37: 进行必要的统计或告警等处理。 Step 37: Perform necessary statistics or alarms.
步骤 38: 消息中的目的信令点编码是本局信令点编码列表中的一个, 也就是说, 当设备收到一条最终目的点就是本点的消息时, 则在本点执行 SCCP (信令连接控制部分)寻址过程,之后执行步驟 39, 也就是说在 SCCP 层能够完全实现逻辑网絡的互通, 不必关心消息的起源网络和目的网络的 逻辑网络标识。 Step 38: The destination signaling point code in the message is one of the local signaling point code list, that is, when the device receives a message that the final destination point is the point, the SCCP (signaling) is performed at the current point. The connection control part) is addressed, and then step 39 is performed, that is to say, the interworking of the logical network can be fully realized at the SCCP layer, and it is not necessary to care about the origin network of the message and the logical network identifier of the destination network.
步骤 39: 进行消息的编路转发。 Step 39: Perform routing of the message.
经过上述过程的描述可以看出, 本发明实现了信令网的互通。 It can be seen from the description of the above process that the present invention implements the interworking of the signaling network.
本发明中, 逻辑网络的实现与 SS7规范没有任何的冲突, 不依赖 MTP3 协议中的 NI, 即应用 NI支持的网络数最多为 4, 而使用逻辑网絡功能可以支 持理论上数量无限的信令网络; In the present invention, the implementation of the logical network does not conflict with the SS7 specification, and does not depend on the NI in the MTP3 protocol, that is, the number of networks supported by the application NI is up to 4, and the logical network function can support a theoretically unlimited number of signaling networks. ;
本发明能够实现与本点一个信令点编码相连的逻辑网络之间在 MTP3 层实现互通的功能。 The invention can realize the function of realizing interworking between the logical networks connected to one signaling point code of the present point at the MTP3 layer.
需要说明一点,步骤 33中的判断,表明是否需要通过 SCCP层实现互通, 而只有消息中的目的信令点编码是本局点即是本局信令点编码列表中的一 个, 该消息才可能送到 SCCP层进行处理, 否则在 MTP3就被转发了, 不会 送到 SCCP层,这是七号信令网络规划的标准内容,由网络规划部门决定 STP 设备是否需要 SCCP层的参与。 这样, 对于在 MTP3层不能互通的逻辑网络, 可以采用现有技术在 SCCP层能够实现信令网之间的互通。 It should be noted that the judgment in step 33 indicates whether interworking is required through the SCCP layer, and only the destination signaling point code in the message is one of the local signaling points in the local signaling point list, and the message may be sent. The SCCP layer processes it, otherwise it is forwarded in MTP3 and will not be sent to the SCCP layer. This is the standard content of SS7 network planning. The network planning department determines whether the STP device needs the participation of the SCCP layer. In this way, for a logical network that cannot communicate with each other at the MTP3 layer, the interworking between the signaling networks can be implemented at the SCCP layer by using the prior art.
