FIG. 1 is a schematic diagram of an apparatus for service type adaptation in a transmission system. As shown in FIG. 1 , the apparatus 100 includes a source end 110 and a sink end 120 , and the transmission between the source end 110 and the sink end 120 is through a 100G/200G line 130 . The source end 110 includes a multi-service mapping and de-mapping module 111 and a line framing and de-framing module 112 , and the sink end 120 includes a line framing and de-framing module 121 and a multi-service mapping and de-mapping 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, eCPRI, and ETH. The method mainly obtains information such as the service type and rate of the client side service 140 of the transmission equipment manually, manually configures the client side service type and rate of the source end 110 manually, and manually allocates the number and position of the line side time slots according to the client side service rate; The end 110 encapsulates the service information into the data communication network DCN message and transmits it to the sink end through the 100G/200G line 130. The sink end 120 parses the service information from the DCN message and sends it to the hardware to realize the configuration of the source and sink ends. be consistent. The transmission equipment generally includes BBU, RRU, and Ethernet equipment, wherein the source end 110 is generally deployed on the BBU side, and the sink end 120 is generally deployed on the RRU side. In the process of manual configuration, the data obtained mainly depends on the user's delivery.

Due to the wide variety of transmission equipment client-side equipment, it is time-consuming and laborious to manually obtain the client-side service type. At the same time, the client-side equipment itself supports a variety of services. When modifying the service type, the configuration of the transmission equipment needs to be modified in conjunction, which is inconvenient for manual operation. Moreover, the current transmission equipment does not have the ability to automatically adapt, and can only require the wireless equipment to use a fixed rate mode. The function of the wireless CPRI port protocol to support dynamic switching of interface rates during operation cannot be used.

FIG. 2-A is a flowchart of a method for service type adaptation in a transmission system provided by the first embodiment of the present application. The method and apparatus provided in this application can be applied to all pipeline technologies that support hybrid service transmission including OTN.

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

A method for service type adaptation in a transmission system, as shown in Figure 2-A, for the execution class step, with S as the initial number, for the judgment class step, with J as the initial number, including:

Step S20: Service type configuration on the source client side. Then proceed to step S21.

In the source device, each client side port corresponds to a client side configuration switching module, and the source client side service type is switched in turn within the preset service set range; the client side configuration switching module completes the service type configuration, and the service type configuration includes: Configuration of interfaces between different devices on the client side and data processing paths at different rates.

Step S21: The source-end device reads the preset client-side alarm set. Then proceed to step J20.

After the client-side configuration switching module in the source device completes the service type configuration, the service identification and alarm monitoring module reads the preset client-side alarm set under the configuration. The client-side alarm set includes physical layer alarms. For example, CPRI services can use CPRI LOS (Loss of Signal, loss of signal) alarms and CPRI LOF (Loss of Frame, loss of frames) alarms; GE services can use LOSS of SYNC alarms.

LOF alarm: The location 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*1chip). The time interval is fixed; therefore, the mechanism for judging the LOF alarm is to start timing from the last detection of K28.5, and then check whether the data of K28.5 is at a fixed time interval. If not, it is considered that the data is out of alignment and lost. Frame, there is a smoothing mechanism inside the logic, if the threshold is exceeded, an LOF alarm is reported.

LOS alarm: to judge whether there is an optical signal in the optical link, it is usually detected by the optical module or Serdes (serializing/deserializing circuitry, serial-parallel circuit) hardware, and the intensity of the optical signal is judged after photoelectric conversion. The above alarm is usually caused by a physical connection due to hardware detection.

It is worth noting that the alarm "pull" mentioned in this application includes the meaning of "assert" in English, namely: Set the alarm to its "active" state; the alarm mentioned in this application "Deassert" includes the meaning of "deassert" in English, namely: Set the alarm to its "inactive" state (the alarm is set to the "inactive" state).

Step J20: The source-end device determines whether the service type configuration matches the actual client-side service type. If yes, then go to step S22; if not, go to step S20.

The service identification and alarm monitoring module monitors, and within the service matching judgment time window T1 (the time length of T1 can be preset), if the corresponding alarm remains in the canceled state (it cannot be interrupted in the middle), the time reaches the matching threshold T2 (the time length of T2 can be preset). If ), it is considered that the current client side configuration matches the actual client side service type, and then proceeds to step S22; otherwise, it is considered that the current client side configuration does not match the actual client side service, and then proceeds to step S20.

Step S22: The source device automatically calculates the number of time slots on the line side. Then proceed to step S23.

According to the determined service type and rate on the source client side, the required number of line side time slots is automatically calculated.

Step S23: The source-end device automatically allocates idle time slots on the line side.

The source device automatically searches for idle time slots on the line side and allocates them to client-side services.

Here, the first embodiment of the present application provides a method for automatically allocating time slots by a source device, as shown in FIG. 3 .

Take the source device with a total of 15 client-side ports and line-side OTU4 (80 1.25G time slots) as an example. A time slot allocation table with an effective address range of 0 to 79 is designed in the source device, and addresses 0 to 79 correspond to 80 time slots on the line side respectively. The data bit width of the table is 4-bit, where 0 to 14 indicate that the time slot has been occupied by ports 0 to 14 on the client side in turn, and 15 indicates that the time slot is free. When the client-side port N (N<15) is adapted to the 10GE service type, the time slot allocation process is as follows:

Step 301: Obtain the number of time slots corresponding to the 10GE service.

The number of timeslots corresponding to the 10GE service is obtained by looking up the table, and the number of timeslots to be allocated is set to 8.

Step 302: Clear the idle time slot counter to zero.

Step 303: Count the number of idle time slots.

Read the time slot allocation table addresses 0 to 79 in sequence. If the read value is 15, the idle time slot counter is incremented by 1; if the read value is N, the idle time slot counter is incremented by 1, and the data of this address is modified to 15.

Step 304: Determine whether to enable time slot allocation.

After completing the traversal of the time slot allocation table, if the idle time slot counter is less than 8, that is, the idle bandwidth is not enough to transmit 10GE services, go to step 306; slot allocation, go to step 305 .

Step 305: Allocate time slots. Then proceed to step S24.

Read the addresses 0 to 79 of the time slot allocation table in turn. If the read value is 15 and the time slot counter to be allocated is greater than 0, the counter of the time slot to be allocated is decremented by 1, and the data of the changed address is modified to N, and the time slot allocation is completed. After the traversal of the allocation table, the time slot allocation ends.

Step 306: Return the time slot allocation failure alarm to the client side, and end the method, do not execute the steps of S24-S26 and J21, and wait for the client side's subsequent instructions.

The time slot allocation failure alarm is used to indicate that the idle bandwidth on the line side is insufficient to transmit services.

Step S24: The source-end device sends the client-side service information to the sink-end device. Then proceed to S25.

The bandwidth allocation control information generation module in the source device uses the line overhead on the line side to send the client-side service information to the sink end, and the client-side service information includes service type, service rate, number of allocated time slots, and the like. Signaling overhead can be saved through line overhead transmission.

Step S25: The sink device extracts the client-side service information and completes the client-side service interface configuration.

The bandwidth allocation control information parsing module of the sink device extracts the client-side service information from the line-side line overhead, and controls the service demapping according to the extracted client-side service information. The client-side configuration switching module of the sink-end device completes the configuration of the client-side service type at the sink end. .

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

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

During the operation of the transmission service, the service identification and alarm monitoring module monitors, and within the service mismatch judgment time window T3 (the time length of T3 can be preset), if the accumulated time corresponding to the alarm pulling state (with interruptions in the middle) reaches the time limit. If the threshold T4 is configured (the time length of T4 can be preset), it is considered that the actual client-side service type has changed, and the process goes to S20; otherwise, it goes to S26.

Step S26: Continue to transmit the service.

The transfer process continues, and the client-side configuration switching module does not perform the switching service.

If the client-side device supports dynamic switching of service types or interface rates, the switching period is usually in seconds (s). After the client side switches the service type or interface rate, the hardware implements the client side alarm detection, and the completion time is at the microsecond (us) level; the hardware implements the client side rate reconfiguration and alarm detection, and the completion time is at the millisecond (ms) level. Even for a fully hardware-implemented circuit, an attempt of a service type or interface rate, corresponding to steps S20 to S24 at the source end, will not take more than 10ms, then for the second (s)-level service type switching cycle of the client device, It is completely feasible to find the required service type for adaptation by completely traversing the service types supported by the device.

The first embodiment of the present application provides a method for service type adaptation in a transmission system. After the service type is configured on the source end client side, the source end device reads the preset client side alarm set under the configuration, and the source end device determines the service type. After the type configuration matches the actual service type, the source device automatically calculates the number of time slots required on the line side and automatically allocates idle time slots on the line side. The source device sends the client-side service information to the sink device to achieve consistent source and sink configurations. . The method is based on alarm monitoring of client side service characteristics, determines the client side service type, automatically allocates the number of line time slots, and realizes automatic adaptation of end-to-end service transmission.

It should be noted that, unless otherwise specified, the specific description of some technical features in one embodiment may also be applied to explain the corresponding technical features mentioned in other embodiments. For example, the description about CPRI LOS alarm, CPRI LOF alarm and LOSS of SYNC alarm in one embodiment may be applicable to CPRI LOS alarm, CPRI LOF alarm and LOSS of SYNC alarm in all other embodiments.

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

This application takes the service type CPRI3 of a BBU device and the preset service type set CPRI3 to CPRI5 corresponding to the source client port as an example. The line rate corresponding to CPRI2 is 1.2288Gbps, the line rate corresponding to CPRI3 is 2.4576Gbps, and the line rate corresponding to CPRI4 The rate 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 10.1376Gbps.

As shown in FIG. 4 , a method for determining a service type by a client-side port of a source device in a transmission system provided by an embodiment of the present application includes:

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

The client side configuration switching module of the source device switches the client side service type to CPRI5, and configures the high-speed interface rate to 4.9152Gbps. The service identification and alarm monitoring modules are monitored. Because the actual service types do not match, the CPRI LOS alarm and the CPRI LOF alarm remain in the raised state. Condition (T1>T2, T1, T2 can be preset), CPRI5 service adaptation fails.

After the client-side configuration switching module in the source device completes the service type configuration, the service identification and alarm monitoring module reads the preset client-side alarm set under the configuration. The client side alarm set includes physical layer alarms. For example, CPRI services can use CPRI LOS (Loss of Signal, loss of signal) alarms and CPRI LOF (Loss of Frame, loss of frames) alarms; GE services can use LOSS of SYNC alarms.

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

The client side configuration switching module of the source device switches the client side service type to CPRI4, and configures the high-speed interface rate to 3.072Gbps. The service identification and alarm monitoring module performs monitoring. Because the actual service types do not match, the CPRI LOS alarm and CPRI LOF alarm remain in the raised state; if the alarm is not satisfied within the T1 time window, the alarm remains in the canceled state (it cannot be interrupted in the middle) and reaches the T2 time. Condition (T1>T2, T1 and T2 can be preset), CPRI4 service adaptation fails.

Step 403, the client side service type is switched to CPRI3, and the adaptation is successful.

The client side configuration switching module of the source device switches the client side service type to CPRI3, and configures the high-speed interface rate to 2.4576Gbps. The service identification and alarm monitoring module monitors. Since the actual service type matches, the CPRILOS alarm and the CPRI LOF alarm are canceled within the (T1-T2) time (T1>T2, T1, T2 can be preset), which satisfies the T1 time window. If the internal alarm remains in the canceled state (it cannot be interrupted in the middle) and reaches the time T2, the CPRI3 service adaptation is successful.

The third embodiment of the present application provides a method for a client-side port of a source-end device to cope with changes in client-side service types.

In this application, the service type of a BBU device is changed from CPRI3 to CPRI1, and the preset service set CPRI1 to CPRI3 corresponding to the source client port is taken as an example. The line rate corresponding to CPRI2 is 1.2288Gbps, the line rate corresponding to CPRI3 is 2.4576Gbps, and CPRI4 The corresponding line rate 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 10.1376Gbps.

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

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

The client-side service type of the source device was originally adapted to CPRI3. The service identification and alarm monitoring module performs monitoring. Due to the change of the actual service type, the CPRI LOS alarm and the CPRI LOF alarm remain in the raised state, which satisfies the accumulated time of the alarm raised state within the T3 time window (there may be a gap in the middle) to reach the time of T4. (T3>T4, T3, T4 can be preset), CPRI3 service mismatch.

After the client-side configuration switching module in the source device completes the service type configuration, the service identification and alarm monitoring module reads the preset client-side alarm set under the configuration. The client side alarm set includes physical layer alarms. For example, CPRI services can use CPRI LOS (Loss of Signal, loss of signal) alarms and CPRI LOF (Loss of Frame, loss of frames) alarms; GE services can use LOSS of SYNC alarms.

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

The client side configuration switching module of the source device switches the client side service type to CPRI2, and configures the high-speed interface rate to 1.2288Gbps. The service identification and alarm monitoring modules are monitored. Because the actual service types do not match, the CPRI LOS alarm and the CPRI LOF alarm remain in the raised state. Condition (T1>T2, T1 and T2 can be preset), CPRI2 service adaptation fails.

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

The client side configuration switching module of the source device switches the client side service type to CPRI1, and configures the high-speed interface rate to 0.6144Gbps. The service identification and alarm monitoring module performs monitoring. Because the actual service types match, the CPRILOS alarm and the CPRI LOF alarm are cancelled within the (T1-T2) time, which satisfies that the alarm remains cancelled within the T1 time window (it cannot be interrupted in the middle). Condition of T2 time (T1>T2, T1, T2 can be preset), CPRI1 service adaptation is successful.

The fourth embodiment of this application provides a method for adapting service types in a transmission system. It is worth noting that the alarm "pull" mentioned in this application includes the meaning of "assert" in English, that is: Set the alarm to its “active” state (the alarm is set to the “active” state); the alarm “deassert” mentioned in this application includes the meaning of the English “deassert”, namely: Set the alarm to its “inactive” state (the alarm is set to “inactive” "state).
