Said method includes: a base station receives a downlink data block from a base station controller; the downlink data block from said base station controller is coded, the consistency between the block number of said downlink data block and the block number calculated by said base station is not checked before being coded; said coded downlink data block is transmitted to a user device via an air interface. Comparing with the prior art, the effect on the data service, as the service is not able to be executed, is avoided during re- synchronization period that the frame number is out of synchronism with the block number; otherwise, a fixed cache does not be introduced when receiving data packets, therefore the performance of the data service is improved.

Description

Data processing method, device and system

The embodiments of the present invention relate to the field of communications, and in particular, to a data processing method, apparatus, and system. Background technique

A synchronization state to be reached between the BTS (Base Transceiver Station) and the Base Station Controller (BSC), that is, when the data block sent by the BSC arrives at the BTS for encoding. The block number of the data block is identical to the block number derived from the BTS coded frame number. The frame number block number synchronization is a guarantee for the normal scheduling of data services in the air interface. How to achieve the frame number block number synchronization is a relatively mature technology at present, and how to maintain the synchronization state is currently a relatively important link.

An existing method for maintaining the frame number block number synchronization is performed by a jitter buffer (Jitter Buffer, abbreviated as Jitbuf). Specifically, the BTS sets a fixed buffer when receiving the BSC downlink packet service data packet. The cache is typically 40ms (milliseconds), allowing packets to be sorted in the cache and correcting out-of-order within a certain range. In addition, Jitbuf also has a receiving window and an encoding index, and determines the actual storage location of the received data according to the downlink data block block number and the receiving window lvalue, and then, according to the current encoding index, the data block under the index is taken. Encode. As shown in FIG. 1, it is assumed that the link is in the synchronization state, and the block number of the downlink data block is received when the downlink data block with block number 6 is received in the receiving window (assuming that the size is the time corresponding to buffering 4 data blocks). The distance from the receiving window is 2, and is stored according to the current encoding index plus 2, indicating that the current downlink block with the block number of 6 needs to be buffered for 2 blocks, that is, the data block needs to be 40 ms later. Performing the air interface coding; further, if the coding index 2 corresponds to the block number 4 calculated by the base station coding frame number, when it is the case that the downlink data block of the block number is 6 is encoded, the block number calculated by the base station coding frame number is also exactly 6. It is consistent with the block number of the received downlink data block, thus maintaining the frame number block number synchronization.

A disadvantage of the above existing method for maintaining the frame number block number synchronization is that when the clock of the BSC and/or the clock of the BTS is unstable, the step is lost due to the accumulated difference between the BSC and the BTS clock, and then the adjustment is performed for a period of time. Resynchronization, the inability to perform services during the adjustment period has a great impact on the data service; on the other hand, the fixed cache introduced when receiving the packet service data packet also affects the performance of the packet data service. Summary of the invention

Embodiments of the present invention provide a data processing method, apparatus, and system, which can improve performance of a data service.

The data processing method provided by the embodiment of the present invention includes: receiving, by the base station, a downlink data block sent by the base station controller;

And encoding the downlink data block sent by the base station controller, and verifying whether the block number of the downlink data block is consistent with the block number calculated by the base station before encoding;

And transmitting the encoded downlink data block to the user equipment by using an air interface.

The data processing apparatus provided in this embodiment of the present invention includes: a receiving module, configured to receive a downlink data block that is sent by a base station controller;

And an encoding module, configured to encode, by using the downlink data block received by the receiving module, whether the block number of the downlink data block is consistent with the block number calculated by the base station before encoding, and is not verified;

The data processing system provided by the embodiment of the present invention includes the data processing device and a base station controller that sends a downlink data block to the device.

The block number is verified. Therefore, compared with the prior art, the influence of the inability of the service on the data service during the resynchronization of the frame number block number is eliminated, and the data packet is received.

detailed description

Referring to FIG. 2-1, a schematic flowchart of a data processing method provided by an embodiment of the present invention may be performed by a base station BTS or other communication entity having a function similar to BTS. The method of the example in Figure 2-1 mainly includes the steps:

S201. The base station receives a downlink data block that is sent by the base station controller.

S202. Encode a downlink data block that is sent by the base station controller.

Different from the prior art, in the embodiment provided by the present invention, before the downlink data block sent by the base station controller is encoded, the BTS estimates the block number and the BTS of the downlink data block sent by the base station controller (for example, Whether the block number of the downlink data block sent by the base station controller is consistent with the block number calculated by the BTS, as long as it is correctly received downlink data block. Even if the block number is inconsistent with the block number calculated by the BTS according to the coded frame number, the BTS is immediately encoded, or the frame number block number synchronization is not performed before the downlink data block sent by the base station controller is encoded. No judgment.

It should be noted that, in the data service, the "block number" corresponding to the data block is a resource used for scheduling or transmitting uplink data or downlink data. When a block number is used by a data block (whether scheduled or transmitted), the block number can no longer be used by other data blocks at the same time. For convenience of description, in the embodiment of the present invention, such a resource is referred to as a block number resource. For example, in the data service, 52 frames constitute a multiframe, including 12 data blocks (each data frame constitutes one data block). Block numbers numbered 0 through 11 correspond to scheduling or transmission for data blocks numbered 0 through 11.

S203. Send the encoded downlink data block to the user equipment by using an air interface.

According to the embodiment of the present invention, the base station directly encodes the downlink data block sent by the base station controller, that is, whether the block number of the downlink data block that is not sent by the base station controller is equal to the block number calculated by the BTS coded frame number. The verification is performed, and the encoded downlink data block is sent to the user equipment through the air interface. Therefore, compared with the prior art, the effect that the service cannot be performed on the data service during the resynchronization after the frame number block number is lost is eliminated. In addition, since the fixed buffer is not introduced when the data packet is received, the data service is also improved. Performance.

In the embodiment provided by the present invention, since the BTS does not directly encode the block number of the downlink data block sent by the base station controller, which is equal to the block number of the BTS estimation (for example, according to the coded frame number), the BTS does not directly perform coding. The uplink data block and the downlink data block transmitted on the air interface are not actually scheduled by the BSC. In this case, scheduling conflicts of uplink data blocks may occur.

In order to avoid the scheduling conflict of the uplink data block, if the BTS does not check whether the block number of the downlink data block sent by the base station controller is equal to the block number calculated by the BTS, the downlink data block sent by the base station to the base station controller After the encoding is performed, before the sending, the method further includes the following steps: scheduling the downlink data block, determining whether the scheduling performed on the downlink data block forms a collision with the scheduling of the uplink data block after the subsequent data block, and if a conflict is formed, changing the pair The downlink data block performs scheduled scheduling information, and sends the changed scheduling information to the user equipment. For example, the changed scheduling information is sent to the user equipment along with the encoded downlink data block through the air interface.

In the embodiment of the present invention, after the modified scheduling information is sent to the user equipment, the method may further include: after adding the scheduling reference value of the downlink data block to the scheduled uplink data block, feeding back to the base station controller to respond to the downlink data. Block scheduling. The scheduling reference value of the downlink data block can be regarded as a label, which is a specific value given when the base station controller sends the downlink data block, and the base station backfills the specific value in the scheduled uplink data block as a pair. The response made by the scheduling of the downstream data block. In this way, after receiving the specific value, the base station controller can know which data blocks are successfully scheduled, so as to clearly know which data to schedule.

In an embodiment of the present invention, if the scheduling of the downlink data block is an Uplink Statement Flag (USF) scheduling, the base station determines that the scheduling of the downlink data block is The method for determining the collision of the subsequent uplink data block to form a conflict may be as shown in FIG. 2-2, and includes the following steps:

52021, find a resource reservation table;

52022, determining whether scheduling of the next block of resources adjacent to the block number corresponding to the downlink data block has been reserved for the uplink data block;

If the next block number resource corresponding to the block number of the downlink data block is not reserved for the uplink data block, the process proceeds to step S2023, and if the next block number resource corresponding to the block number of the downlink data block has been reserved for the uplink data If the scheduling of the block is performed, it is judged that the scheduling of the downlink data block is delayed by the scheduling of the uplink data block, and the flow proceeds to step S2024. This is because the USF scheduling is characterized in that when the scheduling of a downlink data block is USF scheduling, it means that the next element resource immediately adjacent to the corresponding block number of the downlink data block should be the user equipment that receives the downlink data block. (Reputed as UEi) is used when sending an uplink data block. Therefore, if USF scheduling is performed on a certain downlink data block, the next element resource immediately adjacent to the corresponding block number of the downlink data block is reserved as another user equipment. When the UE2 transmits an uplink data block, the UEi that receives the downlink data block may collide with the UE2 when transmitting the uplink data block.

52023. Perform scheduling on the downlink data block according to a previously scheduled scheduling policy.

52024, changing scheduling information for scheduling downlink data blocks;

Once it is determined that the scheduling of the downlink data block (assumed to be USF scheduling) forms a collision with the scheduling of the subsequent uplink data block, the scheduling information for scheduling the downlink data block may be changed. Specifically, the USF domain scheduled by the USF is invalidated, and then the process proceeds to step S2025.

52025. Send a value of the invalid USF domain to the user equipment.

For example, the value of the USF field that will be invalidated by the air interface can be sent to the user equipment along with the encoded downlink data block.

As shown in FIG. 3, it is assumed that the downlink data block with block number 5 is sent to UEi, and when the USG scheduling is performed for the downlink data block with block number 5, the block number resource with block number 6 has been reserved for UE2. The scheduling, for example, the Relative Reserved Block Period (RRBP) scheduling, that is, the block number resource with the block number of 6 has been reserved for the UE2 to send the uplink data block. Since the block number resource with the block number of 6 has been reserved for the UE2 to send the uplink data block, the downlink data block with the block number of 5 is performed. During USF scheduling, the block number resource with block number 6 can no longer be used as UEi to send uplink data blocks. Otherwise, a collision will occur. Therefore, when the downlink data block with block number 5 is USF scheduling, the scheduling at this time conflicts with the scheduling of the uplink data block with block number 6. The USF field of the downlink data block with block number 5 can be invalid.

In another embodiment of the present invention, if the scheduling of the downlink data block is a relative reserved block period (Relative

For the scheduling of the Reserved Block Period, the RRBP, the base station determines whether the scheduling of the downlink data block is a collision with the scheduling of the uplink data block, as shown in FIG. 2-3, and includes the following steps:

S'2021, searching for a resource reservation table;

S'2022, determining whether the RRBP value corresponds to whether the block number resource has been reserved for scheduling of the uplink data block; Step S, 2023, if the RRBP value corresponds to the scheduling of the block number resource reserved for the uplink data block, determining The scheduling of the downlink data block forms a collision with the scheduling of the uplink data block, and the flow proceeds to step S, 2024. This is because the RRBP scheduling is characterized in that when the scheduling of a certain downlink data block is RRBP scheduling, it means that the block number resource corresponding to the RRBP value should be received by the user equipment (referred to as UEi) that receives the certain downlink data block. When the uplink data block is sent, if the RRBP scheduling is performed on a certain downlink data block, if the block number resource corresponding to the RRBP value has been reserved for other users, it is used as the UE2), when the uplink data block is sent, the The UEi of a certain downlink data block conflicts with the UE2 when transmitting the uplink data block when transmitting the uplink data block.

S'2023: Perform scheduling on the downlink data block according to the originally scheduled scheduling policy; S'2024, change scheduling information for scheduling the downlink data block;

Once it is judged that the scheduling of the downlink data block (assumed to be the RRBP scheduling) forms a collision with the scheduling of the subsequent uplink data block, the scheduling information for scheduling the downlink data block is changed. Specifically, the RRBP domain scheduled by the RRBP is invalidated, or the RRBP value is modified, and then the process proceeds to step S, 2025.

S'2025: Send the value of the invalid RRBP field or the modified RRBP value to the user equipment. For example, the value of the RRBP field that is invalidated or the modified RRBP value can be edited through the air interface. The downlink data blocks after the code are sent together to the user equipment.

It should be noted that, in the embodiment of the present invention, the RRBP value may be 0, 1, 2, or 3, which respectively represents a downlink data block whose receiving block number is n (for data traffic, n minimum value is 0, not more than 11). The UE will send the upstream data block using the block number resource with block number n+3, n+4, n+5 or n+6.

As shown in FIG. 4, it is assumed that the downlink data block with block number 3 is sent to the user set to UEi), and when the downlink data block with block number 3 is RRBP scheduled, the RRBP value is 0 (indicating that the received block number is The UEi of the downlink data block of 3 will transmit the uplink data using the block number resource of block number 6), and the block number resource of block number 6 has been reserved for other user equipment (referred to as UE2) for some scheduling, for example , USF scheduling, that is, the block number resource with block number 6 has been reserved for UE2 to send the uplink data block. The block number resource with the block number of 6 is reserved for the UE2 to send the uplink data block. Block, otherwise, a conflict will occur. Therefore, when the downlink data block with the block number 3 is the RRBP scheduling, the scheduling at this time forms a collision with the scheduling of the uplink data block with the block number of 6, and the RRBP field of the downlink data block with the block number 3 can be invalid. Or modify the RRBP value. For example, if the block number resource with block number 7 is not scheduled for the uplink data block of UE2 (ie, sending uplink data), the RRBP value (which is 0) at this time can be modified to 1; similarly, if the block number is The block number resource of 8 does not have the scheduling of the uplink data block of UE2 (that is, the uplink data is sent), and the RRBP value (0) at this time can also be modified to 2, and the rest of the process can be analogized.

In the embodiment of the present invention, the base station determines whether the scheduling performed on the downlink data block is a resource reservation table that is found by the scheduling of the uplink data block to form a conflict. The resource reservation table may be such a resource reservation table: A block number resource reserved for scheduling of uplink data blocks is identified. The process of creating a resource reservation table may include: first creating an empty table; and then identifying a scheduling type of the current downlink data block, for example, an uplink state identifier USF scheduling and a relative reserved block period RRBP scheduling, etc.; The scheduling type of the scheduling of the secondary downlink data block identifies the scheduled block number resource reserved for the uplink data block on the created empty table. For example, a block number resource containing 12 bits (bits) may be used to reserve the block number resource reserved for the scheduling of the uplink data block, and each bit corresponds to a reserved condition of the scheduled block number resource of the uplink data block. Use the bit "Γ to identify a block number resource has been reserved, bit "0" to identify a block number resource has not been reserved, or vice versa, use the bit "0" A certain block number resource has been reserved, and the bit "1" identifies that a block number resource has not been reserved. It is to be understood that the specific use of the form of the block number resource is not limited in the embodiment of the present invention. After the scheduling of the block forms a conflict, the scheduling information of the scheduling of the downlink data block is changed. Therefore, the scheduling of the uplink data block can be avoided, and the air interface scheduling can be effectively protected.

Referring to FIG. 5, it is a schematic diagram of a logical structure of a data processing apparatus according to an embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown. The data processing device illustrated in FIG. 5 may be an access network device such as a base station, and the device includes a receiving module 501, an encoding module 502, and an encoded data transmitting module 503, where:

The receiving module 501 is configured to receive a downlink data block that is sent by the base station controller.

The encoding module 502 is configured to encode a downlink data block that is sent by the base station controller, and check whether the block number of the downlink data block is consistent with the block number calculated by the base station before encoding, that is, the base station Whether the block number of the downlink data block sent by the controller is consistent with the block number calculated by the BTS, as long as the block is correctly received, even if the block number is inconsistent with the block number calculated by the BTS according to the coded frame number, the coding module 502 is also immediately coded, or is determined not to synchronize the frame number block number before encoding the downlink data block sent by the base station controller;

The coded data sending module 503 is configured to send the coded downlink data block to the user equipment by using an air interface.

It should be noted that, in the implementation of the foregoing data processing apparatus, the division of each functional module is merely an example. In actual applications, the foregoing function allocation may be performed according to requirements, such as configuration requirements of corresponding hardware or convenience of implementation of software. It is completed by different functional modules, that is, the internal structure of the data processing device is divided into different functional modules to complete all or part of the functions described above. Moreover, in practical applications, the corresponding functional modules in this embodiment may be implemented by corresponding hardware, or may be executed by corresponding hardware. For example, the foregoing receiving module may have the foregoing receiving base station control. The hardware of the downlink data block sent by the device, for example, the receiver, may also be a general processor or other hardware device capable of executing a corresponding computer program to perform the foregoing functions; and the encoding module as described above may have the foregoing control of the base station. The hardware of the downlink data block sent by the device for encoding function, such as an encoder, may also be capable of executing a corresponding computer program from A general processor or other hardware device that performs the aforementioned functions.

Since the encoding module 502 directly encodes the downlink data block sent by the base station controller, the uplink data block and the downlink data block transmitted on the air interface are not actually scheduled by the BSC. In this case, scheduling conflicts of uplink data blocks may occur. In order to avoid the scheduling conflict of the uplink data block, in the case where the BTS does not check whether the block number of the downlink data block sent by the base station controller is equal to the block number calculated by the BTS, the data processing apparatus illustrated in FIG. 5 may further include The scheduling module 601, the determining processing module 602, and the scheduling information sending module 603, as shown in FIG. 6, the data processing apparatus provided by another embodiment of the present invention, wherein:

a scheduling module 601, configured to schedule the downlink data block;

The determining processing module 602 is configured to determine whether the scheduling performed on the downlink data block forms a conflict with the scheduling performed by the uplink data block, and if a conflict is formed, change scheduling information for scheduling the downlink data block;

The scheduling information sending module 603 is configured to send the changed scheduling information to the user equipment, for example, sending the changed scheduling information to the user equipment together with the encoded downlink data block through an air interface.

If the scheduling performed by the downlink data block is an uplink state identifier USF scheduling, the determination processing module 602 of the example of FIG. 5 may include a first determining unit 701 and a first modifying unit 702, as shown in FIG. Another embodiment provides a data processing apparatus, wherein:

The first determining unit 701 is configured to determine, by searching the resource reservation table, whether the next block resource adjacent to the block number of the downlink data block has been reserved for scheduling the uplink data block, and if yes, determine The scheduling performed by the downlink data block forms a collision with the scheduling of the uplink data block, and the judgment is based on: when the scheduling of a certain downlink data block is USF scheduling, it means that the block number corresponding to the downlink data block is immediately adjacent. The next block number resource should be used when the user equipment (referred to as UEi) that receives the downlink data block sends the uplink data block. Therefore, if the USF scheduling is performed on a certain downlink data block, the block number corresponding to the downlink data block is immediately adjacent. The next block of resources has been reserved for use by the other user equipment (denoted as UE2) when transmitting the uplink data block, and the UEi receiving the downlink data block will collide with the UE2 when transmitting the uplink data block, and For a detailed description, reference may be made to the foregoing method embodiment FIG. 3 and its corresponding description; The first modifying unit 702 is configured to: when the determining result of the first determining unit 701 is YES, the USF domain scheduled by the USF is set to be invalid. In this case, the scheduling information sending module 603 is specifically configured to invalidate the The value of the USF field is sent to the user equipment. For example, the value of the USF field that is set to be invalid can be sent to the user equipment along with the encoded downlink data block through the air interface.

The judgment processing module 602 of the example of FIG. 6 may also include a second judging unit 801 and a second modifying unit 802. As shown in FIG. 8, the data processing apparatus according to another embodiment of the present invention, wherein:

The second determining unit 801 is configured to determine, by searching the resource reservation table, whether the RRBP value corresponding to the block number resource has been reserved for scheduling the uplink data block, and if yes, determining the scheduling of the downlink data block. The scheduling of the uplink data block forms a conflict, and the resource reservation table identifies a block number resource reserved for scheduling of the uplink data block, and the judgment is based on when a scheduling of a downlink data block is scheduled by the RRBP. , means that the block number resource corresponding to the RRBP value should be used when the user equipment (referred to as UEi) that receives the certain downlink data block sends the uplink data block. Therefore, if RRBP scheduling is performed on a certain downlink data block, When the block number resource corresponding to the RRBP value has been reserved for use by another user equipment (referred to as UE2) to transmit an uplink data block, the UEi receiving the certain downlink data block sends an uplink data block with the UE2 when transmitting the uplink data block. For a more detailed description, reference may be made to FIG. 4 of the foregoing method embodiment and its corresponding description;

The second modification unit 802 is configured to set the RRBP field of the RRBP to be invalid, or modify the RRBP value. At this time, the scheduling information sending module 603 is specifically configured to use the value of the RRBP field that is invalid. The falsified RRBP value is sent to the user equipment. For example, the value of the RRBP field that is set to be invalid or the modified RRBP value may be sent to the user equipment along with the encoded downlink data block through the air interface.

In the data processing apparatus illustrated in FIG. 7 or FIG. 8 above, the first determining unit 701 or the second determining unit 801 determines whether the scheduling performed on the downlink data block forms a resource for the collision of the scheduling of the subsequent uplink data block. The reservation table may be a resource reservation table in which a block number resource reserved for scheduling of the uplink data block is identified on the resource reservation table. The process of creating a resource reservation table may include: first creating an empty table; and then identifying a scheduling type of the current downlink data block, for example, an uplink state identifier USF scheduling and a relative reserved block period RRBP scheduling, etc.; The scheduling type of the scheduling of the secondary downlink data block is reserved for the uplink data block on the created empty table. The scheduled block number resource is identified. For example, a block number resource containing 12 bits (bits) may be used to reserve the block number resource reserved for the scheduling of the uplink data block, and each bit corresponds to a reserved condition of the scheduled block number resource of the uplink data block. Use bit "" to identify a block number resource has been reserved, bit "0" identifies a block number resource has not been reserved, or vice versa, use bit "0" to identify a block number resource has been reserved, bit" Γ Identifies that a block number resource has not been reserved. It can be understood that the specific use of the form identifies the block number resource, which is not limited in this embodiment.

The data processing apparatus of any of the examples of Figures 5 through 8 further includes a reference value feedback module 901, such as the data processing apparatus provided by another embodiment of the present invention, as shown in Figure 9. The reference value feedback module 901 is configured to: after adding the scheduling reference value of the downlink data block to the scheduled uplink data block, feed back to the base station controller in response to scheduling the downlink data block. The scheduling reference value of the downlink data block can be regarded as a label, which is a specific value given when the base station controller sends the downlink data block, and the base station backfills the specific value in the scheduled uplink data block as a pair. The response made by the scheduling of the downstream data block. In this way, after receiving the specific value, the base station controller can know which data blocks are scheduled successfully, so as to clear which data to be scheduled next.
