Description

Method and device for service type adaptation in transmission system

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for service type adaptation in a transmission system.

Background

In The 5G (fifth generation mobile communication technology) Network era, C-RAN (Centralized Radio Access Network) and D-RAN (Distributed Radio Access Network) coexist, and there are many types of wireless side services, including forward CPRI (Common Public Radio Interface), OBSAI (Open Base Station Architecture), eCPRI (enhanced Common Radio Interface), backhaul Ethernet (Gigabit Ethernet), XGE (Ten-Gigabit Ethernet), and 25-Gigabit Ethernet. As a transport device supporting forward or backward unified bearer, there may even be a scenario where wireless traffic and other non-wireless traffic (e.g., SDH, Synchronous Digital Hierarchy, etc.) are carried in a mixed manner.

At present, aiming at the problem of service type adaptation between transmission devices, the method mainly adopted is to manually acquire information such as service types and rates of client sides of the transmission devices and then manually configure the service types and rates of client side ports of the transmission devices; and manually distributing the number and the position of the line side time slots according to the service type and the rate information of the client side port. Because the variety of the client side equipment of the transmission equipment is various, the manual operation for completely acquiring the service type of the client side is time-consuming and labor-consuming, meanwhile, the client side equipment supports various services, the configuration of the transmission equipment needs to be modified in a linkage manner when the service type is modified, and the manual operation is inconvenient. The current transmission equipment has no automatic adaptive capacity, and only requires the wireless equipment to use a fixed rate mode, and the function of supporting dynamic interface rate switching in the operation process by a wireless CPRI port protocol cannot be used.

Therefore, a method and apparatus for service type adaptation in a delivery system are needed to implement automatic adaptation of client-side service access.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The performance of the 5G wireless network, whether SA (stand-alone networking) or NSA (Non-stand-alone networking), is greatly improved, but functionally, the wireless network basically inherits the original 3G/4G, logical channels, protocol layering, and the like. The functions of a wireless network are generally split into a Remote Radio Unit (RRU) and a Base Band Unit (BBU). For the baseband processing of the BBU, the processing can be further split into a non-real-time slow processing module (CU) and a real-time fast processing module (DU).

The forward transmission refers to transmission between the RRU and the BBU, and is used for bearing a CPRI signal with a fixed code rate; the feedback refers to transmission between the BBU and the core network, and carries an IP message.

Fig. 1 is a schematic diagram of an apparatus for service type adaptation in a transmission system. As shown in FIG. 1, the device 100 includes a source terminal 110 and a sink terminal 120, and the source terminal 110 and the sink terminal 120 transmit through a 100G/200G line 130. The source end 110 includes a multi-service mapping demapping module 111 and a line framing demapping module 112, and the sink end 120 includes a line framing demapping module 121 and a multi-service mapping demapping module 122. The source end 110 receives the client side service 140, and the client side service 140 includes service types such as CPRI, OBSAI, eccri, ETH, and the like. The method mainly includes the steps that information such as service types and rates of client side services 140 of transmission equipment is obtained manually, the client side service types and rates of a source end 110 are configured manually, and the number and positions of time slots on a line side are allocated manually according to the client side service rates; the source terminal 110 encapsulates the service information into a DCN message of a data communication network and transmits the service information to the sink terminal through a 100G/200G line 130, and the sink terminal 120 parses the service information from the DCN message and issues the service information to hardware, so as to keep the configuration of the source terminal consistent with that of the sink terminal. The transmission device generally includes a BBU, an RRU, and an ethernet device, wherein the source terminal 110 is generally disposed on the BBU side, and the sink terminal 120 is generally disposed on the RRU side. The data acquired in the manual configuration process mainly depends on the user to issue.

Because the variety of the client side equipment of the transmission equipment is various, the manual operation for completely acquiring the service type of the client side is time-consuming and labor-consuming, meanwhile, the client side equipment supports various services, the configuration of the transmission equipment needs to be modified in a linkage manner when the service type is modified, and the manual operation is inconvenient. The current transmission equipment has no automatic adaptive capacity, and only requires the wireless equipment to use a fixed rate mode, and the function of supporting dynamic interface rate switching in the operation process by a wireless CPRI port protocol cannot be used.

Fig. 2-a is a flowchart of a method for service type adaptation in a transmission system according to a first embodiment of the present application. The method and the device provided in the present application can be applied to all pipe technologies supporting hybrid service delivery including OTN.

A method for service type adaptation in a transmission system, the method is performed by a source device 210, a sink device 220 and a 100G/200G line 230, as shown in fig. 2-B, wherein the source device 210 includes a client side configuration switching module 211, a service identification and alarm monitoring module 212, a bandwidth allocation control information generating module 213, a multi-service mapping demapping module 214, a line framing deframing module 215; the sink device 220 includes a line framing and de-framing module 221, a client-side configuration switching module 222, a bandwidth allocation control information parsing module 223, and a multi-service mapping and de-mapping module 224.

A method for service type adaptation in a transmission system, as shown in fig. 2-a, for performing class steps with S as the first letter number and for judging class steps with J as the first letter number, comprising:

step S20: and configuring the service type of the source client side. Subsequently, the flow proceeds to step S21.

In the source end equipment, each client side port corresponds to a client side configuration switching module, and the stream switching of the service type of the source end client side is performed within a preset service set range; and the client side configuration switching module is used for completing the service type configuration, and the service type configuration comprises the configuration of interfaces between different devices and different rate data processing paths on the client side.

Step S21: the source device reads a preset client side alarm set. Step J20 is then entered.

After the client side configuration switching module in the source end device completes the service type configuration, the service identification and alarm monitoring module reads a preset client side alarm set under the configuration. The client side alarm set includes physical layer alarms such as: the CPRI service may use a CPRI LOS (LOSs of Signal) alarm and a CPRI LOF (LOSs of Frame) alarm; the GE traffic may use a LOSS of synchronization LOSS of SYNC alarm.

LOF alarm: the position and data of the synchronization control information K28.5 of each superframe are fixed, and the transmission rate of each superframe is also fixed (255 x 1chip), so the time interval for transmitting every two synchronization control information is fixed; therefore, the mechanism for judging the LOF alarm is to start timing from the last detection of K28.5, detect whether the data of K28.5 is detected again at a fixed time interval, if not, consider that the data is not aligned, have a frame loss, logically have a smoothing mechanism inside, and report the LOF alarm if the threshold is exceeded.

LOS alarm: whether an optical signal exists in an optical link is judged, the optical signal is usually detected by an optical module or Serdes (serial/parallel circuit) hardware, the intensity of the optical signal is judged after photoelectric conversion, once the intensity is lower than an intensity threshold, an alarm is reported, and the hardware detection usually results from physical connection.

It should be noted that the alarm "pull" mentioned in the present application includes the meaning of "alert" in english, that is: setthe alarm to its active state (alarm set to active state); the alarm "revocation" mentioned in the present application includes the meaning of the english "deassert", that is: set the alarm to its "inactive" state (alarm Set to "inactive" state).

Step J20: the source end device judges whether the service type configuration is matched with the actual client side service type, if yes, the step S22 is executed; otherwise, the process proceeds to step S20.

The service identification and alarm monitoring module monitors, in a service matching judgment time window T1 (the time length of T1 can be preset), if the time for keeping the corresponding alarm in a revocation state (the middle can not be interrupted) reaches a matching threshold T2 (the time length of T2 can be preset), the current client side configuration is considered to be matched with the actual client side service type, and then the step S22 is carried out; otherwise, the current client-side configuration is not considered to match the actual client-side service, and the process proceeds to step S20.

Step S22: the source device automatically calculates the number of line-side slots. Subsequently, the flow proceeds to step S23.

And automatically calculating the number of the time slots on the required line side according to the determined service type and rate of the source client side.

Step S23: the source device automatically distributes idle time slots on the line side.

The source device automatically searches the idle time slot of the line side and distributes the idle time slot to the client side service.

A first embodiment of the present application provides a method for a source device to automatically allocate a timeslot, as shown in fig. 3.

Take 15 client-side ports of the source device and the OTU4(80 slots of 1.25G) as an example. A time slot distribution table with an effective address range of 0-79 is designed in source end equipment, and addresses 0-79 respectively correspond to 80 time slots on a line side. The data bit width of the table is 4-bit, wherein 0-14 sequentially indicates that the time slot is occupied by client side ports 0-14, and 15 indicates that the time slot is idle. When client-side port N (N <15) is adapted to 10GE traffic type, the procedure for timeslot assignment is as follows:

step 301: and acquiring the number of time slots corresponding to the 10GE service.

And obtaining the number of the time slots corresponding to the 10GE services as 8 through table lookup, and setting a counter of the time slots to be allocated to be 8.

Step 302: and clearing the idle time slot counter.

Step 303: and counting the number of idle time slots.

Sequentially reading the addresses 0-79 of the time slot distribution table. If the read value is 15, adding 1 to the idle time slot counter; if the read value is N, the free slot counter is incremented by 1 and the data for that address is modified to 15.

Step 304: it is determined whether to initiate timeslot allocation.

After the traversal of the time slot allocation table is completed, if the idle time slot counter is less than 8, that is, the idle bandwidth is not enough to transmit the 10GE service, the step 306 is entered; if the idle slot counter is greater than or equal to 8, i.e., the idle bandwidth is sufficient to transmit 10GE, slot allocation is initiated and step 305 is entered.

Step 305: time slots are allocated. Subsequently, the flow proceeds to step S24.

Sequentially reading addresses 0-79 of the time slot allocation table, if the read value is 15 and the counter of the time slot to be allocated is greater than 0, subtracting 1 from the counter of the time slot to be allocated, modifying the data of the changed address into N, and finishing the time slot allocation after traversing the time slot allocation table.

Step 306: and returning a time slot allocation failure alarm to the client side, ending the method, not executing the steps of S24-S26 and J21, and waiting for the subsequent indication of the client side.

The time slot allocation failure alarm is used for indicating that the idle bandwidth at the line side is not enough to transmit the service.

Step S24: and the source end equipment sends the client side service information to the sink end equipment. Subsequently, the process proceeds to S25.

The bandwidth allocation control information generation module in the source end equipment transmits client side service information to the host end by utilizing the line overhead on the line side, wherein the client side service information comprises service types, service rates, allocation time slot numbers and the like. Signaling overhead may be saved by line overhead transmission.

Step S25: and the host equipment extracts the client side service information and completes the configuration of the client side service interface.

The bandwidth allocation control information analysis module of the host equipment extracts the client side service information from the line side line overhead, the service demapping is controlled according to the extracted client side service information, and the client side configuration switching module of the host equipment completes the client side service type configuration of the host.

The service information of the client side comprises service types, service rates, the number of allocated time slots and the like, and the service type configuration comprises the configuration of interfaces between different devices of the client side and different rate data processing paths.

Step J21: the source end device monitors whether the service type of the source end client side changes.

In the service transmission operation process, a service identification and alarm monitoring module monitors, and in a service mismatch judgment time window T3 (the time length of T3 can be preset), if the accumulated time (which can be interrupted in the middle) corresponding to the alarm pull-up state reaches a mismatch threshold T4 (the time length of T4 can be preset), the actual client side service type is considered to be changed, and the operation enters S20; otherwise, the process proceeds to S26.

Step S26: traffic continues to be transmitted.

The transmission process continues and the client side configures the switching module not to perform the switching service.

If the client side device supports dynamic switching of the service type or the interface rate, the switching period is usually in the order of seconds(s). After the client side switches the service type or the interface rate, the hardware realizes the alarm detection of the client side, and the completion time is in the microsecond (us) level; the hardware implements client-side rate reconfiguration and alarm detection with completion times on the order of milliseconds (ms). Even if an attempt of a service type or an interface rate for a circuit implemented by full hardware takes no more than 10ms corresponding to the steps S20-S24 at the source end, a method of completely traversing service types supported by a device to find a required service type for adaptation is completely feasible for a service type switching period of a second (S) level of a client-side device.

A first embodiment of the present application provides a method for service type adaptation in a transmission system, where after a service type of a source client is configured, a source device reads a preset client alarm set under the configuration, after the source device determines that the service type configuration matches an actual service type, the source device automatically calculates the number of time slots required by a line side and automatically allocates idle time slots on the line side, and the source device sends service information of the client to a sink device, so as to achieve consistency of source and sink configurations. The method is based on client side service characteristic alarm monitoring, determines client side service types, automatically allocates line time slot quantity and realizes automatic adaptation of end-to-end service transmission.

For example, the descriptions of the CPRI LOS alarm, CPRI LOF alarm, and LOSs of SYNC alarm in one embodiment may be applied to the CPRI LOS alarm, CPRI LOF alarm, and LOSs of SYNC alarm in all other embodiments.

A second embodiment of the present application provides a method for determining a service type for a client-side port of a source device in a transmission system.

Taking a certain BBU device service type CPRI3 and a corresponding source-side port preset service type set CPRI 3-CPRI 5 as an example, the line rate corresponding to CPRI2 is 1.2288Gbps, the line rate corresponding to CPRI3 is 2.4576Gbps, the line rate corresponding to CPRI4 is 3.0720Gbps, the line rate corresponding to CPRI5 is 4.9152Gbps, the line rate corresponding to CPRI6 is 6.1440Gbps, the line rate corresponding to CPRI7 is 9.8304Gbps, and the line rate corresponding to CPRI8 is 10.1376 Gbps.

As shown in fig. 4, a method for determining a traffic type for a client-side port of a source device in a transmission system according to an embodiment of the present application includes:

step 401, the service type of the client side is switched to CPRI5, and the adaptation fails.

The client side configuration switching module of the source end device switches the client side service type to CPRI5, and configures the high-speed interface rate to 4.9152 Gbps. The service identification and alarm monitoring module monitors, and because the actual service types are not matched, the CPRI LOS alarm and the CPRI LOF alarm keep in a pull-up state, and the condition that the alarm keeping cancellation state (the middle cannot be interrupted) reaches the time of T2 in the time window of T1 is not met (T1> T2, T1 and T2 are preset), so that the service adaptation of the CPRI5 fails.

After the client side configuration switching module in the source end device completes the service type configuration, the service identification and alarm monitoring module reads a preset client side alarm set under the configuration. The client side alarm set includes physical layer alarms such as: the CPRI service may use a CPRI LOS (LOSs of Signal) alarm and a CPRI LOF (LOSs of Frame) alarm; the GE service may use the LOSS of SYNC alarm.

Step 402, the service type of the client side is switched to CPRI4, and the adaptation fails.

The client side configuration switching module of the source end equipment switches the client side service type to CPRI4, and configures the high speed interface rate to be 3.072 Gbps. The service identification and alarm monitoring module monitors, and the CPRI LOS alarm and the CPRI LOF alarm keep a pull-up state because the actual service types are not matched; the condition that the alarm keeping revocation state (the middle can not be interrupted) reaches the time T2 within the time window T1 is not met (T1> T2, T1 and T2 can be preset), and the service adaptation of the CPRI4 fails.

And step 403, switching the service type of the client side to CPRI3, and successfully adapting.

The source end equipment client side configuration switching module switches the client side service type to CPRI3, and configures the high speed interface rate to be 2.4576 Gbps. The service identification and alarm monitoring module monitors, and because the actual service types are matched, the CPRILOS alarm and the CPRI LOF alarm are cancelled within the time (T1-T2) (T1> T2, T1 and T2 can be preset), so that the condition that the alarm keeping cancellation state (the middle can not be interrupted) reaches the time T2 within the time T1 window is met, and the service adaptation of the CPRI3 is successful.

A third embodiment of the present application provides a method for a source device client-side port to cope with a client-side traffic type change.

Here, for example, a service type of a certain BBU device is changed from CPRI3 to CPRI1, and corresponding source-side client-side port preset service sets CPRI1 to CPRI3 are taken, a line rate corresponding to CPRI2 is 1.2288Gbps, a line rate corresponding to CPRI3 is 2.4576Gbps, a line rate corresponding to CPRI4 is 3.0720Gbps, a line rate corresponding to CPRI5 is 4.9152Gbps, a line rate corresponding to CPRI6 is 6.1440Gbps, a line rate corresponding to CPRI7 is 9.8304Gbps, and a line rate corresponding to CPRI8 is 10.1376 Gbps.

As shown in fig. 5, a method for a source device client-side port to cope with a change in a client-side traffic type provided in an embodiment of the present application includes:

step 501, the client side service type changes, and the source end device service is mismatched.

The source device client side traffic type has been originally adapted to the CPRI 3. The service identification and alarm monitoring module monitors, and because the actual service type changes, the CPRI LOS alarm and the CPRI LOF alarm keep the pull-up state, and satisfy the condition that the cumulative time (which may be interrupted) of the alarm pull-up state reaches the time T4 in the time window T3 (T3> T4, T3 and T4 are preset), and the service mismatch of CPRI3 is realized.

Step 502, the service type of the client side is switched to CPRI2, and the adaptation fails.

The source device client side configuration switching module switches the client side service type to CPRI2, and configures the high-speed interface rate to 1.2288 Gbps. The service identification and alarm monitoring module monitors, and because the actual service types are not matched, the CPRI LOS alarm and the CPRI LOF alarm keep in a pull-up state, and the condition that the alarm keeping cancellation state (the middle cannot be interrupted) reaches the time of T2 in the time window of T1 is not met (T1> T2, T1 and T2 are preset), so that the service adaptation of the CPRI2 fails.

Step 503, the service type of the client side is switched to CPRI1, and the adaptation is successful.

The client side configuration switching module of the source end equipment switches the client side service type to CPRI1, and configures the high speed interface rate to be 0.6144 Gbps. The service identification and alarm monitoring module monitors, and because the actual service types are matched, the CPRILOS alarm and the CPRI LOF alarm are cancelled within the time (T1-T2), so that the condition that the alarm cancellation state (which cannot be interrupted) reaches the time T2 within the time window T1 is met (T1> T2, T1 and T2 can be preset), and the service adaptation of the CPRI1 is successful.
