Technical Field

The present application relates to the field of transport network technologies, and in particular, to a method and an apparatus for transmitting a network signal of a service, an electronic device, and a computer storage medium.

Background

Currently, a Packet Transport Network (PTN) adopts L2+ L3 networking for carrying 4G LTE services. Wherein, L2 refers to physical layer and link layer; l3 refers to the physical, link and network layers. The backbone layer also has bridge points that do not form a network structure that deploys all of the L3 layers. The service path between the X2 stations is: access-convergence-backbone convergence-core bridging-backbone convergence-access. Because different rendezvous point group rings can share the bandwidth, and the shared bandwidth can cause that the relay link close to the backbone rendezvous point also needs to bear the access ring service under other rendezvous points, the bandwidth sharing can increase the load of the network relay link and reduce the effective utilization rate of the bandwidth.

In addition, in some scenarios in a 5G network, such as the enhanced Machine Type of Communication (eMTC) based on LTE evolution, which is mainly object-to-object Communication, the Communication process is sensitive to time delay. However, the current PTN network architecture needs to transmit a network signal of a service based on a service path between X2 stations, so that the transmission delay is high.

Therefore, how to improve the effective utilization rate of the bandwidth and further reduce the transmission delay is a technical problem that needs to be solved by those skilled in the art.

The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.

Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

As can be seen from the background art, in the current PTN network architecture, the effective utilization rate of the bandwidth is low, which results in higher transmission delay.

In order to solve the problem of the prior art, embodiments of the present application provide a method and an apparatus for transmitting a network signal of a service, an electronic device, and a computer storage medium. First, a network signal transmission method of a service provided in an embodiment of the present application is described below.

Fig. 1 is a flowchart illustrating a network signal transmission method for a service according to an embodiment of the present application. As shown in fig. 1, the network signal transmission method of the service includes:

s101, receiving a network signal transmission request.

S102, determining target equipment and target service corresponding to the target equipment based on the network signal transmission request.

S103, sending a network signal of a target service to target equipment based on a slice packet network architecture of a preset 5G bearer network; the slice packet network architecture of the 5G bearer network comprises a plurality of aggregation rings, and each aggregation ring comprises an access ring and an aggregation point bearing the access ring.

After receiving a network signal transmission request, the network signal transmission method of the service determines target equipment and target service corresponding to the target equipment based on the network signal transmission request; and sending a network signal of the target service to the target equipment based on a preset slice packet network architecture of the 5G bearer network. Because the slice packet network architecture of the 5G bearer network comprises a plurality of aggregation rings, and each aggregation ring comprises an access ring and an aggregation point bearing the access ring, the effective utilization rate of the bandwidth can be improved, and the transmission delay is further reduced.

In one embodiment, the convergence points in the convergence ring include backbone convergence points and non-backbone convergence points, each of which is connected to a backbone convergence point by an optical fiber.

In one embodiment, the convergence ring is networked around a pre-defined core office and backbone convergence point.

In one embodiment, the slice packet network architecture of the 5G bearer network is a logical four-port network architecture made based on a physical three-point networking mode.

The following describes the above with a specific scenario embodiment.

First, a backbone network scheme is explained. The embodiment provides a Slicing Packet Network (SPN) architecture based on a 5G bearer Network. In the networking architecture provided by this embodiment, each access ring and a rendezvous point bearing each access ring are used as a convergence ring, and the convergence point in each convergence ring is connected to a backbone rendezvous point in the convergence ring, where backbone rendezvous is a node convergence for a central area of a part of an urban area and a flag-county-two node or an important regional convergence node. The urban area has edge zones and in order to relieve the pressure of backbone convergence, part of urban convergence machine rooms are converged on convergence equipment of a core building. Therefore, the pressure on the aspect of power supply matching caused by convergence to the backbone in urban areas is avoided. As the convergence power generation of the backbone in the urban area needs to coordinate the residents nearby except the local building, too many equipment systems are not suitable to be converged in the backbone convergence, and the local building also converges part of services. The structure can change the bandwidth shared by a plurality of access rings into the bandwidth shared by each access ring, thereby avoiding the bandwidth waste caused by the bandwidth sharing and improving the effective utilization rate of the bandwidth. The convergence point in each convergence ring is connected with the backbone convergence point in the convergence ring through an optical fiber, as shown in fig. 2. In another embodiment, all convergence rings in a segment of an urban area converge around a core office and a backbone with a close distance into a pair of backbone convergence pairs for networking, which requires that core devices at two ends of the office a are placed to form an open-ended networking, so that the capability of backbone convergence in the urban area is ensured, and network safety pressure caused by backbone convergence failure is reduced, as shown in fig. 3. In another embodiment, a physical three-point networking mode is adopted, a logical four-port network is made, the convergence of devices and routes in a backbone machine room convergence part and subsequent MESH evolution based on an SDN are adapted, and the networking structure is provided. When a backbone convergence point in the network is down, the core building equipment 2 undertakes service protection, and the safety is greatly improved.

The convergence layer scheme is described below. In such a region of a vast area as an inner Mongolia, some flag counties cannot use one or two nodes of the location of the flag counties to converge the services of all the flag counties, and at this time, two large township nodes need to be added according to the geographic positions to converge another part of services. At this time, four points are arranged on an Optical Transport Network (OTN) from city to county, and the OTN channels are split into two different backbone convergence rings, as shown in fig. 4.

L3 sinks to each convergence point, allowing the carrier network to be further flattened. In the current networking architecture, the service path between Xn stations is: access-convergence-backbone convergence-sub-backbone convergence-core bridging-backbone convergence-sub-backbone convergence-access. In this embodiment, since L3 sinks to each convergence point in each subsystem, and the L3 edge sinks to each backbone convergence point in the convergence ring, the Xn inter-station traffic path becomes: access-convergence-backbone convergence-access. That is, the number of devices passed by the Xn service path under the dual-uplink networking architecture is greatly reduced, thereby further reducing the service delay.

In order to establish a unified network, in the above scheme, the backbone aggregation node, except for converging 5G, may sink 5G edge computing and Broadband Access Server (BRAS), which becomes a comprehensive service bearer. The common aggregation node is provided with an important Optical Line Terminal (OLT), the C-RAN node is provided with a small OLT, so that the important OLT in the aggregation node can realize double-uplink protection through a direct-connection optical cable or an OTN, and unified one-network bearing of a 5G and home wide network is realized.

The access terminal scheme is described below. The access end scheme comprises: an integrated service access area and original access ring scheme, a small OTN scheme and a wavelength division multiplexing passive optical network (WDM-PON).

(1) The scheme of the integrated service access area and the original access ring comprises the following steps:

as shown in fig. 5, the original access ring scheme utilizes optical cross in an integrated service access area to implement integrated bearer from a Base Band Unit (BBU) to a remote point, and a passive coarse wavelength division scheme may be used if optical fiber resources are insufficient. The scheme needs to share the optical cable with a home-wide network, and unified planning and maintenance can be realized. The coarse wavelength division scheme is to utilize the existing optical cable to open the C-RAN, and is divided into two scenes: 1. the method is characterized in that a remote station is opened, when a source station of the remote station is a self-reserved station, and when more than 4 remote stations are brought by the source station, the source station can be defined as a small C-RAN station, Small Packet Network (SPN) devices are placed, and 5G stations are opened by using coarse wavelength division to make use of old original access layer optical cables. 2. The first station adjacent to the access ring carried by the C-RAN convergence machine room can be directly opened as a C-RAN access point.

An original Packet Transport Network (PTN) access ring is transformed into a C-RAN mode, and the specific method comprises the following steps:

for example, 10 stations are provided on the original access ring, and 10 stations can be distributed to five C-RAN convergence machine rooms at two ends of the access ring, so that 5 access nodes are opened by using a 1:12 or 1:18 coarse wave component in a manner of one core per node and intermediate station hopping. Thus, each sink node opens 5 base stations on both sides, and 10 base stations are provided in total. After a double-span access layer optical cable is divided into half, all stations of an access ring can be opened by using 5 cores in total, and half fiber cores are saved compared with the mode that all stations of the access ring are brought into a convergence node. The opening by using the original access ring optical cable has no problem basically. The aggregation node is provided with a chain type networking, and a passive wave deployment C-RAN node is carried out by using a fiber core of a chain.

(2) Small OTN protocol:

when C-RAN networking is adopted, protection is difficult to realize, and an optical cable direct connection mode is that a fiber core is sufficient and the base station is protected when the optical cable is not interrupted at all. The existing semi-active wavelength division technology is generally suitable for protecting a base station in chain type or star type networking and is suitable for a scene in which the base station is concentrated, but the situation that the station is dispersed cannot be used, the situation that the station is dispersed is best by using a ring type network, the best way for saving optical cable resources and pipeline resources is provided, when an active antenna processing unit (AAU) in an important organization such as the party and the government needs to be protected, a ring structure is formed by using a small OTN, wave channel level protection is carried out, and safety is improved.

For ring networking, the OTN scheme is as shown in fig. 6, active OTN devices are arranged at two ends of an AAU site and a Distribution Unit (DU), and support multiple AAUs to share optical fiber resources through a WDM technology. White light modules are installed on the AAU and the DU, 1 active OTN device is respectively arranged at two ends of the white light modules, 2-core trunk optical fibers are generally occupied, the processing mode of the OTN device is adopted, and the time delay can not meet the rigorous requirement of forward transmission, so that the simplified mapping hierarchy and the cost are generally adopted to reduce the time delay and realize the cost. The mode is generally used in a scene of improving the safety in a C-RAN mode, optical cables are arranged in a convergence machine room area where DU/BBU is centrally placed, different optical cables are adopted by access loops of transmission wavelength division access, active small wavelength division equipment on the same transmission wavelength division access loop only occupies 1 pair of optical fibers, and can comprehensively bear other base stations and group special lines, and main and standby protection can be realized after the active small wavelength division equipment is made into a ring network.

Calculating the bandwidth to determine the single wave rate according to the following modes, and calculating the bearing bandwidth of the transmission single access node: the single-node transmission bandwidth capacity b is equal to the number Fn of the signal sources of each frequency band of the radio remote station and the bandwidth capacity requirement corresponding to the signal sources of each frequency band plus the number Fm of the comprehensive access signal sources of each type and the bandwidth capacity requirement corresponding to the signal sources of each type.

(3) WDM-PON scheme:

the WDM-PON is a wavelength-independent scheme, and a model for 5G forward transport bearer is shown in fig. 7, where an Optical Network Unit (ONU) and an OLT are respectively disposed at two ends of an AAU and a DU, and a trunk Optical cable occupies 1 core. The key technical point of the scheme is that a colorless optical module is adopted, and the optical module can automatically adjust the proper wavelength. The ONU has two types, namely SFP + type and ONU type. The WDM-PON system in the ONU type requires that an AAU (architecture) is provided with a white light module to be connected with the ONU, and more optical modules are consumed. The SFP + type ONU does not need a white light module, and the SFP + type color light ONU is directly inserted into the AAU. The ONU in the SFP + form saves more space and has better application prospect. This scheme can be used with a home wide OLT only the user side PON board is of a different type.
