Description

Uplink pre-scheduling processing method, device and system

This application claims priority to Chinese Patent Application No. 201110048088.0, entitled "Upstream Pre-Scheduled Processing Method, Apparatus and System", filed on February 28, 2011, the entire contents of which is incorporated herein by reference. In the application. Technical field

The embodiments of the present invention relate to the field of communications, and in particular, to an uplink pre-scheduling processing method, apparatus, and system.

Background technique

The user equipment (User Equipment, hereinafter referred to as UE) needs to obtain the uplink scheduling authorization of the base station before sending data to the base station, for example, the eNodeB.

In the prior art, the base station generally allocates uplink resources to the UE periodically, so that the UE sends data on the allocated uplink resources. However, the UE often needs to send data to the base station in a sudden manner. For example, when the UE performs a File Transfer Protocol (FTP) service with the network side device, it needs to send a feedback ACK message to the base station in a sudden manner. If the UE does not obtain the uplink scheduling authorization of the base station, the UE needs to send a scheduling request indication (SRI) message to the base station, and the base station can allocate a buffer status report (Buffer State Report) to the UE. The following is abbreviated as: BSR), and the UE is notified by Uplink Grant (UL Grant). After the four transmission time intervals (TTIs), the UE may report the BSR to the base station on the resource; the base station allocates uplink transmission resources for the uplink data of the UE according to the BSR reported by the UE; After the TTI, the UE sends the uplink data to the base station.

Therefore, in the prior art, if the UE has burst uplink data, at least 8 ports are required to complete the scheduling operation of the uplink burst data of the UE. Therefore, the prior art uplink data of the UE bursts. The processing cannot meet the high latency requirements and cannot meet the service quality. (Quality of Service, hereinafter referred to as: QoS) requirements.

The Chinese patent application CN101835262A discloses a resource allocation method, including: the base station determines that the base station has idle schedulable resources; and the base station determines whether the user equipment UE has data to be transmitted; if the judgment result is that the UE has data to be transmitted, the base station according to the preset pre-set The amount of scheduling data actively allocates pre-scheduled resources to the UE. U.S. Patent Application No. 20090109912 A1 discloses a method and apparatus for pre-scheduled uplink resources. The entire contents of this application are incorporated herein by reference.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The general components included in the base station and/or terminal in the following embodiments are no longer listed. These general purpose components include, but are not limited to: baseband processing components; medium RF processing components; transmission components; processors; memory; antenna components; Each base station corresponds to one or more cells. Each cell can serve one or more terminals. Terminals include but are not limited to: mobile phones, notebook computers, wireless communication modules.

FIG. 1 is a flowchart of an embodiment of an uplink pre-scheduling processing method according to the present invention, as shown in FIG. The method of this embodiment may include:

Step 101: Obtain service attribute information of the user equipment. The service attribute information can be used to determine whether the user equipment is likely to send burst uplink data.

For example, a base station, such as an eNodeB or the like, can perform the steps of this embodiment in each TTI.

Specifically, the base station may acquire service attribute information of the UE. The base station may learn the service attribute information in the process of the UE accessing the cell or in the process of the UE sending the uplink data. The service attribute information may reflect whether the UE has the possibility of transmitting burst uplink data to the base station.

It should be noted that the specific content of the service attribute information is not limited in this embodiment. It can be understood by those skilled in the art that any information that can reflect whether the UE has the possibility of bursting uplink data can be used to implement the present invention. The technical solution of the embodiment, and the embodiment does not limit whether the service attribute information is used by the base station in the prior art, or the obtained information is detected by other technical means. In addition, in this embodiment, the base station is not limited to acquiring only the service attribute information of one UE. In actual implementation, the service attribute information of multiple UEs can be obtained.

Step 102: Perform, according to the service attribute information, that the user equipment may send burst uplink data, perform uplink pre-scheduling processing on the user equipment.

If the base station learns that the UE may send burst uplink data according to the obtained service attribute information, the base station may perform uplink pre-scheduling processing on the UE without waiting for the UE to send the SRI. For example, the base station may send a UL Grant message to the UE, and after receiving the UL Grant message, if the UE has burst uplink data, the UE may directly send the burst uplink data to the base station.

It should be noted that, since the base station can determine that multiple UEs can send burst uplink data, the base station can perform uplink pre-scheduling processing on multiple UEs, or according to certain policies, such as priority order, etc. One or a plurality of UEs perform uplink pre-scheduling processing. In this embodiment, the base station may determine, according to the service attribute information of the UE, the UE that may send the burst uplink data, and perform uplink pre-scheduling processing on the UE, so that the UE may send the uplink burst data on the uplink pre-scheduled resource. Therefore, compared with the prior art, the scheduling of the uplink burst data can be completed by using 8 TTIs. This embodiment shortens the scheduling time of the uplink burst data, and can meet the requirements of higher delay requirements and QoS.

2 is a flowchart of another embodiment of an uplink pre-scheduling processing method of the present invention. As shown in FIG. 2, the method in this embodiment may include:

Step 201: Acquire service quality category identification information of the UE.

In order to reduce the implementation complexity of the embodiment, the embodiment may select the information that the base station has stored as the service attribute information. The QoS Class Identifier (hereinafter referred to as QCI) is one of them. The QCI can reflect the service attributes of the UE, and the base station can use the QCI information as a decision basis for whether the UE needs to perform uplink pre-scheduling processing. The QCI information may be service attribute information obtained and stored by the base station from the network side during the process of the UE accessing the network or initiating the service request.

Step 202: Determine, according to the service quality category identifier information, that the UE may send burst uplink data.

The base station can determine whether the UE will send burst uplink data according to the QCI information.

Specifically, for each UE, its corresponding QCI information exists in the base station. The base station may determine, according to the QCI information corresponding to the UE, whether the UE has the possibility of transmitting burst uplink data.

For each UE, it may only open a single service, or may open multiple services at the same time. Correspondingly, the QCI information of each UE may only contain attribute information of a single service, or may Includes attribute information for multiple services. Therefore, in the specific implementation, the following two technical solutions can be included:

If the UE is a single-service UE, that is, the UE only has a single service, the QCI information includes only the attribute information of the service. Therefore, the base station can determine, according to the OCI information of the service, whether the UE has a transmission burst. The possibility of uplink data; If the UE is a multi-service UE, that is, the UE has multiple services enabled at the same time, the QCI information includes the attribute information of each service. Therefore, the base station can determine whether the UE has a transmission burst according to the QCI information of each service. The possibility of uplink data. For example, if the base station determines the QCI information of each service, as long as the QCI information of one service indicates that the UE may send burst uplink data, it is determined that the UE has the possibility of transmitting burst uplink data.

In an embodiment of the present invention, pre-scheduling attribute information may also be set in the QCI information or in information similar to the QCI information. In this way, according to the pre-scheduling attribute information, it can be directly determined that the UE may send burst uplink data, so that uplink pre-scheduling processing can be performed.

Step 203: Determine whether the system level decision condition is satisfied. If yes, execute step 204, otherwise end.

Since the uplink pre-scheduled processing of the burst uplink data of the UE by the base station may affect the normal scheduling of the UE by the base station and the operational performance of the UE, the present embodiment may set a system-level decision condition, so that the base station can be configured according to the system. The resource or performance determines whether uplink pre-scheduling can be performed on the UE that may send burst uplink data.

Specifically, the uplink pre-scheduling may introduce a problem of wasted system resources. Therefore, in this embodiment, the precondition of the uplink pre-scheduling is that the uplink uplink is light, and the physical uplink shared channel (hereinafter referred to as PUSCH). There is a surplus of channel resources. Therefore, in this embodiment, the bandwidth utilization is used as the system decision condition. When the bandwidth utilization is greater than the first threshold, indicating that the PUSCH channel resource may have no redundancy, the base station does not initiate uplink pre-scheduling; and less than the first threshold, indicating the PUSCH channel resource. If there is a surplus, the base station can initiate uplink pre-scheduling.

The uplink pre-scheduling may also introduce the problem of the neighboring area interference. Therefore, the ratio of the pre-scheduled bandwidth to the total bandwidth of the system may be used as the system decision condition. When the ratio of the pre-scheduled bandwidth to the total bandwidth of the system is greater than the second threshold, If the pre-scheduling bandwidth is relatively high, the base station does not start the uplink pre-scheduling. If the pre-scheduling bandwidth is less than the second threshold, the base station can initiate the uplink pre-scheduling. Therefore, the pre-scheduled bandwidth accounts for the total bandwidth of the system. Ratio as a system decision Conditions, the total bandwidth of the uplink pre-scheduling can be limited, thereby reducing interference to the neighboring cell. In specific implementation, the base station may also use the ratio of the current bandwidth utilization and the pre-scheduled bandwidth to the total bandwidth of the system as a system level decision condition. When the two parameters meet the preset conditions at the same time, the base station can determine to start the uplink pre-scheduling process.

It should be noted that the first threshold and the second threshold may be set according to the performance requirements of the base station system, and the like, which is not described in this embodiment.

In addition, the embodiment does not limit the base station to adopt only the above two parameters as the system decision condition, and those skilled in the art may use other parameters to enrich the content of the system decision as needed. For example, since the uplink pre-scheduling may also introduce a problem of increasing the energy consumption of the UE, the base station may also use the pre-scheduling minimum time interval threshold as a system decision condition. Pre-scheduling time interval = current scheduling time - last scheduling time, when the value of the pre-scheduling time interval is smaller than the pre-scheduled minimum time interval, the base station does not initiate uplink pre-scheduling, thereby reducing the number of uplink pre-scheduling of the UE, thereby reducing the UE's Energy consumption.

In addition, it should be noted that there may be no order between the above steps 202 and 203.

Step 204: Obtain a maximum scheduling interval and a corresponding pre-scheduled data volume allowed by each user equipment according to the service quality category identifier information.

After the base station determines to perform uplink pre-scheduling on the UE according to the determinations in step 202 and step 203, the base station may obtain the maximum scheduling interval allowed by the UE and the corresponding pre-adjustment data amount according to the QCI information.

For example, after completing step 204, the base station may establish a pre-scheduled attribute list as shown in Table 1 for each UE. Table 1

Step 205: Calculate and obtain a priority order of each user equipment according to the last scheduled time, the current scheduled time, and the maximum allowed scheduling interval.

The base station may determine that there are multiple UEs that need to perform uplink pre-scheduling, but the system resources, such as the bandwidth, are very limited. Therefore, the base station may form the uplink pre-scheduling queues for the UEs that need to perform the uplink pre-scheduling process, and pre-schedule the uplink. These UEs in the queue are sorted by priority.

Priority = (last scheduled time - this scheduled time) / maximum allowed scheduling interval. The last scheduled time and the scheduled time are all time parameters that the base station can directly obtain.

Step 206: Perform uplink pre-scheduling processing on the user equipment that may send burst uplink data according to the priority order of the user equipment and the corresponding pre-scheduled data volume.

The base station may perform uplink pre-scheduling processing on the UEs in the uplink pre-scheduling queue in sequence according to the priority order. It can be understood that, once the system resources available to the base station are exhausted, the remaining UEs in the uplink pre-arrangement queue will not be subjected to uplink pre-scheduling processing. In a specific implementation, the base station may perform uplink pre-scheduling processing on the UE by using the pre-scheduled data amount in Table 1.

In this embodiment, a system-level pre-scheduling master switch Pre-Allocation-Switch can be designed. The switch can control whether the base station needs to perform the uplink pre-scheduling processing procedure in steps 201 to 206 in this embodiment. For example, the system-level pre-scheduling master switch is enabled, and the base station needs to perform the uplink pre-scheduling processing procedure in steps 201 to 206 in this embodiment; The station does not need to perform the uplink pre-scheduling process flow in steps 201 to 206 in this embodiment.

In this embodiment, the base station may determine, according to the QCI information of the UE, the UE that may send the burst uplink data, and determine whether the base station itself can perform uplink pre-scheduling processing on the UEs that need uplink pre-scheduling through the system-level decision. In addition, in the scheduling process, the priority order of each UE may be fully considered, so that the base station can pre-allocate uplink resources for UEs that may send burst uplink data, and avoid the impact of the uplink pre-scheduling on system performance as much as possible. . Therefore, in this embodiment, compared with the prior art, it is required to complete the uplink burst data scheduling by 8 ΤΉ, which shortens the scheduling time of the uplink burst data, and satisfies the requirements of higher delay requirements and QoS.
