Description

Signaling transmission method, VRRP networking system, first network entity equipment and storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a signaling transmission method, a VRRP networking system, a first network entity device, and a storage medium.

Background

With the continuous development of network technology, the value added service provided by the network needs to be carried in the IP network to form a core network. If voice traffic needs to be carried in the IP network through the IP multimedia subsystem (IP Multimedia Subsystem, IMS), there are VoLTE (Voice over LTE) modes, voNR (Voice over NR) modes, etc. that are common.

At present, in the networking of the core network, since many network entities do not support the dynamic routing protocol, even if the network entities support the dynamic routing protocol, the dynamic routing protocol is limited by many problems such as management overhead, convergence, security and the like, so that static routing configuration is generally adopted for network entity equipment in the core network. In particular, one or more default gateways (default gateway) are assigned to the network entity device, which can simplify complexity of network management and reduce communication overhead of the network entity device, but if a router serving as a default gateway is damaged, all communication using the default gateway as a next hop host is interrupted, and even if a plurality of default gateways are configured, if the network entity device is not restarted, the network entity device cannot be freely switched to other gateways. Therefore, there is a problem that the reliability of the communication path between network entities of the existing core network is poor.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The flow diagrams depicted in the figures are merely illustrative and not necessarily all of the elements and operations/steps are included or performed in the order described. For example, some operations/steps may be further divided, combined, or partially combined, so that the order of actual execution may be changed according to actual situations.

It is to be understood that the terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be noted that, starting from the fourth generation mobile communication technology 4G, the voice implementation is no longer just a voice service or other value added service provided through the circuit switched network. Instead, a manner of carrying Voice services on an Internet Protocol (IP) network, that is, a long term evolution (Voice over LTE) network, is designed through an IP multimedia subsystem (IP Multimedia Subsystem, IMS), so that all services in a circuit domain are "IP" in a 4G network.

The IP multimedia service subsystem is proposed by the third generation partnership project (3rd Generation Partnership Project,3GPP), and the purpose of the IMS is to establish a converged core network which is independent of access and can be shared by a mobile network and a fixed network, and the IMS is an open, access independent, standardized session control architecture supporting multimedia services. With the current development of the fifth generation mobile communication technology 5G, the design of a New air interface (NR) voice scheme of the 5G also extends the way that the 4G carries voice service through the IP network, that is, carries voice service through the 5G network and the IMS system.

However, in the existing IMS existing network networking, many network entity devices do not support the dynamic routing protocol, and even if they do support the dynamic routing protocol, many problems such as management overhead, convergence, security, etc. are limited. It is therefore common to employ static routing configurations for network entity devices, typically by assigning one or more default gateways (DefaultGateway) to the network entity device. The static routing method simplifies the complexity of network management and reduces the communication overhead of network entity devices, but it still has a disadvantage: if a router as a default gateway is damaged, all communications using the gateway as a next hop host must be interrupted.

Even if multiple default static routing gateways are configured, a network entity device cannot be switched to a new gateway without restarting. The virtual routing redundancy protocol (VirtualRouterRedundancyProtocol, VRRP) is used to avoid the drawbacks of statically assigned gateways. However, in the prior art, as shown in fig. 1, fig. 1 is an exemplary schematic diagram of communication of an existing network entity device based on a VRRP gateway. As can be seen from fig. 1, in the prior art, only one VRRP gateway 13 is provided on the switch between the main port 11 and the standby port 12 of the network entity device (not shown in fig. 1), so that the switching of the main and standby communication paths is performed during the communication process between the network entity device and the opposite network entity device. Since the priority of the VRRP gateway to the IP addresses of the primary and secondary network ports is different, as shown in fig. 1, the priority of the VRRP gateway to the IP1 address of the primary network port 11 (for example, 200) is higher than the priority to the IP1 address of the secondary network port 12 (for example, 100).

It should be noted that, the value range of the IP priority is set to 0 to 255 on the VRRP gateway, wherein a larger value indicates a higher priority.

In the normal message transmission process, the CE equipment connected with the main and standby network ports can perform normal main and standby switching through the VRRP gateway. However, if the error rate between the CE device connected to the active/standby network port and the access routing device AR connected thereto is high, interruption of signaling transmission is caused, resulting in interruption of traffic.

The IMS signaling interaction procedure in the prior art is illustratively described with the use of a broad flow control protocol (Stream Control Transmission Protocol, SCTP) in IMS. As shown in fig. 2, fig. 2 is a schematic diagram of SCTP-based signaling interaction in existing IMS. In this embodiment, it is assumed that two SCTP association paths exist between the IMS core network 21 and the second network entity device 22, and the configuration is shown in table 1 below.

TABLE 1

Wherein, for a single coupled first SCTP, two paths are configured, as shown in table 1, the primary path of the first SCTP: a first IP address, a first port CE1 AR1 network opposite end network entity IP3, a first port; backup path of first SCTP: a second IP address, a second port CE1 AR1 network opposite end network entity IP4, a second port; the priority of the main path of the first SCTP is higher than that of the standby path of the first SCTP, and if the main path of the first SCTP is interrupted, the main path of the first SCTP is switched to the standby path of the first SCTP.

For a single coupled second SCTP, two paths are uniformly configured, as shown in table 1, and for a primary path and a secondary path configured for the second SCTP, in the second SCTP, the priority of the primary path of the second SCTP is higher than the priority of the secondary path of the second SCTP. When the primary path of the second SCTP is interrupted, the standby path of the second SCTP may be switched.

As can be seen from table 2, since the primary path of the first SCTP and the primary path of the second SCTP are configured with the same route between the subscriber edge network device and the upstream access route. In the daily use process, because the VRRP gateway preferentially selects the primary path of the first SCTP corresponding to the first IP address on the first CE device 14 to perform signaling transmission, normal signaling transmission is performed through the first CE device 14, and if the first CE device 14 fails or breaks, the VRRP gateway switches to the second CE device 15, so as to ensure that the route is not broken. The networking can be switched normally when the network is normally used or interrupted, but the following problems exist: if the error rate between the first CE device 14 and the first AR23 is high, the SCTP between the first CE device 14 and the first AR23 is interrupted, and thus the traffic is interrupted, although the intra-network routing is not interrupted. This is because when a high decoding rate occurs between the first CE device 14 and the first AR23, the routing configuration of the service address from the first network entity 20 to the second network entity 22 is still the address selected by the VRRP gateway, and at this time, the primary use selected by the VRRP gateway is still on the first CE device 14, and even if the SCTP multipath is switched to the standby link, since the next hop route of the second network entity 22 is that the first AR23 transmits signaling to the first network entity 20, which is still the first CE device 14, the SCTP coupling is still interrupted, and the service is further affected.

The phenomenon of service interruption caused by high error rate between the first CE device 14 and the first AR23 is often referred to as "dead-of-the-air" phenomenon, and is limited by the SCTP path, so that the SCTP link may be affected, thereby affecting the current network service.

Aiming at the problem that the decoding rate between routing devices is high to influence the service in the prior art, the embodiment of the invention provides a signaling transmission method, which can enable a plurality of paths between IMS network entity devices on the premise of not increasing hardware, skillfully utilizes the characteristic of SCTP multipath and well solves the hidden trouble problem of the existing network.

Referring to fig. 3, fig. 3 is a flowchart illustrating an implementation of a signaling transmission method according to an embodiment of the present invention. It should be noted that, the signaling transmission method provided in this embodiment is applied to the VRRP networking system. Exemplary, as shown in fig. 4, fig. 4 is a schematic structural diagram of a VRRP networking system according to an embodiment of the present invention. Controlled by fig. 4, the VRRP networking system 40 includes a first network entity device (not shown in fig. 4), a first CE device 14, and a second CE device 15; the first network entity device 20 includes at least one set of a main network port 11 and a standby network port 12, where the main network port 11 is connected to the first CE device 14, and the standby network port 12 is connected to the second CE device 15; at least two virtual routing redundancy protocol, VRRP, gateways 16 are configured between the first CE device 14 and the second CE device 15.

Referring to fig. 3, the method includes the following steps S301 to S304.

S301, the first network entity device sends a path selection instruction to the first CE device through the main network port.

The first network entity device includes, but is not limited to, IMS functional entity devices, such as I-CSCF (Call Session Control Function), S-CSCF, P-CSCF, and other network elements.

S302, the first CE device receives the path selection instruction, selects a first IP address as an IP address of a service flow through a first VRRP gateway, acquires a first communication path matched with the first IP address for message signaling transmission, and the priority of the first IP address on the first CE device is higher than that of the second IP address on the first CE device.

S303, when the first network entity equipment detects that the state of the first communication path is abnormal, a path switching instruction is sent to the second CE equipment.

S304, the second CE device receives the path switching instruction, selects a second IP address as an IP address of the service flow through a second VRRP gateway, switches to a second communication path matched with the second IP address for message signaling transmission, and the priority of the second IP address on the second CE device is higher than that of the first IP address on the second CE device.

It should be appreciated that the present embodiment includes more than two CE devices by starting multiple VRRP gateways between the same pair of active-standby network interface boards, where the number of VRRP gateways depends on the number of customer edge network routing CE devices in the present network, in this embodiment two CE devices are taken as an example, and in other alternative implementations, more than two CE devices may be included. And combining with some differentiated routing strategies, the message signaling flow can be transmitted through different CE devices and the uplink access routing equipment AR, so that the function of sharing the signaling path load is realized.

Specifically, a multi-VRRP gateway is started between a main network port and a standby network port of a first network entity device through a first CE device and a second CE device, and the multi-VRRP gateway is coupled with the second network entity device based on multi-home addresses in SCTP, and the first network entity device respectively sends messages to the plurality of VRRP gateways so as to realize that a first communication path matched with a first IP address is preferentially walked on the first CE device, a second communication path matched with a second IP address is preferentially walked on the second CE device, and the function of sharing signaling path loads is realized.

It should be understood that, when the error rate between the CE device and the uplink access routing device AR is high, the uplink AR may be differentiated from the IP address of the first network entity device by the CE device through the open shortest route priority OSPF dynamic routing protocol, so as to ensure that the first IP address to the first network entity device is preferentially paired with the first CE device, and the second IP address to the first network entity device is preferentially paired with the second CE device.

Specifically, after the first network entity device detects the abnormal state of the first communication path, the method further includes:

the second CE device sends information of the second communication path to a second access routing device AR based on an open shortest path by a priority protocol, so that the second AR routing device sends indication information of response signaling returned through the second communication path to the second network entity device, and the second AR is an uplink routing device of the second CE device.

In some embodiments, the first communication path and the second communication path are communication paths established according to stream control transmission protocol SCTP association information.

Wherein, the SCTP coupling information includes: the source address of the first network entity device, the destination address of the second network entity device, routing device information between the first network entity device and the second network entity device, and connection network information.

In some embodiments, the routing device information between the first network entity device and the second network entity device includes: information of the user edge network routing equipment and information of the access routing equipment; the user edge network routing equipment is routing equipment connected with the first network entity equipment, and the access routing equipment is uplink routing equipment of the user edge network routing equipment.

Optionally, before the first network entity device sends a path selection instruction to the first CE device through the primary portal, the method further includes: the first network entity determines a corresponding relation between a source address of the first network entity and a destination address of a second network entity; respectively configuring SCTP coupling information between the first network entity and the second network entity according to the corresponding relation; and establishing the first communication path and the second communication path according to the SCTP coupling information.

At least one SCTP coupling path is included between the first network entity and the second network entity, at least two communication paths are configured under each SCTP coupling path, and the first communication path and the second communication path belong to the same SCTP coupling path.

As can be seen from the above analysis, in the signaling transmission method provided by the embodiment of the present invention, at least two virtual routing redundancy protocol VRRP gateways are configured between the active and standby network ports of the first network entity device through the user edge routing device, and different priorities corresponding to the IP addresses of the first network entity device are respectively configured on different user edge routing devices, so as to ensure that the first network entity device can be freely switched to other gateways in the active and standby network port switching process, so that the reliability of communication between network entities is effectively improved on the premise of not increasing hardware, and the stability of communication between network entities is further ensured.

An exemplary signaling method provided by an embodiment of the present invention is described below with reference to fig. 5. Referring to fig. 5, the present embodiment exemplarily illustrates the signaling method provided by the present invention by using a broad flow control protocol (Stream Control Transmission Protocol, SCTP) in IMS. Fig. 5 is an interaction schematic diagram of the signaling transmission method provided in the present invention applied to IMS, as shown in fig. 5. In this embodiment, it is assumed that two SCTP association paths exist between the IMS core network 21 and the second network entity device 22, and the configuration is shown in table 2 below.

TABLE 2

As can be seen from table 2, in this embodiment, for a single coupled first SCTP, two paths are configured, which are active and standby paths, for example: the primary path of the first SCTP is: a first IP address, a first port < - >, a first CE device < - >, a first AR < - >, a network < - >, a third IP address, a first port; the standby path of the first SCTP is: the first port is configured to switch to a standby path of the first SCTP after the primary path of the first SCTP is interrupted.

For a single coupled second SCTP, two paths are configured as well, which are respectively corresponding active and standby paths, and in the second SCTP, the priority of the active path of the second SCTP is higher than that of the standby path of the second SCTP. When the primary path of the second SCTP is interrupted, the standby path of the second SCTP may be switched.

As can be seen from table 2, since the primary paths of the first SCTP and the primary paths of the second SCTP are configured with different routes between the customer edge network device and the upstream access route, in the use process, the primary paths of the first SCTP and the primary paths of the second SCTP are respectively corresponding primary links, wherein the first CE device and the second CE device are configured with a first VRRP gateway and a second VRRP gateway, the primary of the first VRRP gateway is located on the first CE device, the primary of the second VRRP gateway is located on the second CE device, the primary path of the first SCTP is selected on the first CE device through the first VRRP gateway when the third IP address is sent, and the primary path of the second SCTP is selected on the second CE device through the second VRRP when the fourth IP address is sent. The load sharing of IMS network output signaling can be realized under the condition of not increasing hardware.

The first port, the second port, the third port, and the fourth port may be configured with different port numbers, for example, 4001, 4002, 4003, 4004, and the like, respectively.

It should be understood that if there is an excessively high decoding rate between the first CE device and the first AR, the signaling sent to the fourth IP address may still take the path from the first AR to the first CE device when the response signaling is returned, resulting in the SCTP coupling being interrupted, in order to prevent this phenomenon from being sent, an open shortest path first (Open Shortest Path First, OSPF) dynamic routing protocol is adopted between the access routing devices AR connected to the CE device, the CE device reallocates the IP addresses on the first network entity device side, so as to ensure that the response signaling transmitted to the first IP address corresponding to the first network entity device side takes precedence over the first SCTP main path to the first CE device, and the response signaling transmitted to the second IP address corresponding to the first network entity device side takes precedence over the second SCTP main path to the second CE device. The transmission problem caused by the signaling return caused by high decoding rate of the first CE equipment and the first AR equipment is solved, and the SCTP coupling link is ensured not to be interrupted. According to the analysis, the signaling transmission method provided by the implementation can effectively eliminate the problem of service blocking caused by the too high error rate between the AR and CE devices, and effectively improves the reliability of the system.

Referring to fig. 6, fig. 6 is a flowchart of a signaling transmission method according to another embodiment of the present application. It should be noted that, in this embodiment, the signaling transmission method is applied to a first network entity device, where the first network entity device includes at least one set of a main network port and a standby network port, the main network port is connected to a first CE device, and the standby network port is connected to a second CE device; configuring at least two Virtual Routing Redundancy Protocol (VRRP) gateways between the first CE device and the second CE device; the method comprises the following steps S601 and S602.

S601, sending a path selection instruction to the first CE device through the main network port to instruct the first CE device to select a first IP address as an IP address of a service flow through a first VRRP gateway, acquiring a first communication path matched with the first IP address for message signaling transmission, wherein the priority of the first IP address on the first CE device is higher than that of the second IP address on the first CE device;

s602, when detecting that the state of the first communication path is abnormal, sending a path switching instruction to the second CE equipment so as to instruct the second CE equipment to select a second IP address as an IP address of a service flow through a second VRRP gateway, switching to a second communication path matched with the second IP address for message signaling transmission, wherein the priority of the second IP address on the second CE equipment is higher than that of the first IP address on the second CE equipment.

It should be noted that, the specific implementation process of each step corresponding to the embodiment of the present invention may refer to the specific implementation process of each step shown in the embodiment of fig. 3, which is not described herein.

As can be seen from the above analysis, the embodiments provided by the present application provide a signaling transmission method, by configuring at least two virtual routing redundancy protocol VRRP gateways between the active and standby ports of the first network entity device through the user edge routing device, and configuring different priorities of the IP addresses corresponding to the first network entity device on different user edge routing devices, so as to ensure that the first network entity device can be freely switched to other gateways in the active and standby port switching process, so that the reliability of communication between network entities is effectively improved without increasing hardware, and the stability of communication between network entities is further ensured.
