Description

A scheduling method and device for concurrent services

technical field

The invention relates to communication technology, in particular to a scheduling method and device for concurrent services based on network load and service rate.

Background technique

With the rapid growth of users of the third generation mobile communication standard (referred to as 3G) and the rapid development of all services, wireless networks have higher and higher requirements for resource allocation, and resource allocation needs to be adjusted according to actual user distribution and needs. Next, maximize the value of the network. TD-SCDMA, Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) system is a system with limited code channels. In the existing network, the uplink and downlink 2:4 configuration is adopted, and the enhanced high-speed packet access in the configuration In the technology (HSPA, High-Speed Packet Access) carrier frequency, the downlink signaling code channel can use 4 times the frame division, while the uplink code channel can open up to twice the frame division. Therefore, compared with the downlink code resources, the uplink code resources Restricted situations are more likely to occur.

In the existing business model, small-traffic packet data domain (PS) services account for an increasing proportion, such as QQ online, heartbeat information, location information, etc. As the duration continues to grow, the probability of concurrent occurrence of services in the circuit bearer domain (CS) also greatly increases. In the traditional scheduling scheme, when the PS service and the CS service are concurrent, they jointly occupy the code combination channel. The CS service adopts the Adaptive Multiple Rate (AMR, Adaptive Multiple Rate) 12.2k coding method, and the CS service and the PS service share 32k resources, occupying 4 code channels with scale factor (SF, Scale Factor) = 16, only use the R4 method, which does not make full use of the code channel resources. In addition, the existing network of TD-SCDMA is configured with R4 carrier, mixed carrier and H carrier, and different carriers have different bearing capacities for CS service and PS service. For example, the downlink configuration of the H carrier has three high-speed physical downlink shared channel (HS-PDSCH, High Speed-Physical Downlink SharedChannel) time slots, only the TS6 time slot can be used to carry CS services, and the carrying capacity of CS services is poor ; There is no HS-PDSCH time slot configured in the R4 carrier, and there is a lack of high-speed shared channels for carrying PS services; compared with the hybrid carrier that uses 2 HS-PDSCH time slots in the downlink time slot, the R4 carrier has the ability to carry PS services Much weaker.

It can be seen that improper carrier scheduling for concurrent services will not only waste code channel resources, but also affect user perception. At the same time, the concurrent service scheduling algorithm in the existing network does not take into account the high proportion of small traffic PS services, which will also cause waste of code channel resources in the resource allocation of concurrent services.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

The scheduling method and device in the embodiments of the present invention are mainly proposed for CS/PS concurrent services, and provide different resource scheduling schemes for concurrent services by monitoring the utilization rate of cell code resources and the size of PS service traffic.

Since the concurrent service is carried by R4 carrier and hybrid carrier, and the resource bottleneck is in the uplink, this application mainly analyzes the utilization rate of the uplink code resource: when the uplink code resource is idle, the concurrent service will be judged according to the size of the PS service data packet The service is scheduled to the R4 carrier or mixed carrier, and the existing DPCH is still used to carry concurrent services or the mixed mode is adopted on the mixed carrier: the CS service is transmitted by the DPCH, and the PS service is transmitted by the HS-PDSCH; The CS service and the PS service are compressed at the same time, so that the compressed CS and PS services each occupy half of the service resources.

Fig. 1 is a schematic diagram of the implementation flow of a method for scheduling concurrent services according to an embodiment of the present invention. As shown in Fig. 1, the method includes the following steps:

Step 101: When the packet data field (PS) service and the circuit bearer field (CS) service occur concurrently, monitor the resource utilization rate of the uplink direction code, and detect the traffic of the PS service in the concurrent service;

Step 102: Scheduling the carrier for transmitting the concurrent service for the concurrent service according to the monitoring situation of the uplink code resource utilization rate and the traffic detection result of the PS service, and determining the transmission mode of the scheduled carrier.

Preferably, the carrier transmitting the concurrent service is an R4 carrier or a mixed carrier; the transmission mode includes a compressed mode and an uncompressed mode.

Specifically, the determining the transmission mode of the scheduled carrier according to the monitoring situation of the resource utilization rate of the uplink direction code and the traffic detection result of the PS service includes:

When the code resource utilization rate in the uplink direction is less than or equal to the set first threshold value, it is determined to enable the uncompressed mode for both the PS service and the CS service;

When the code resource utilization rate in the uplink direction is greater than the first threshold and less than the second threshold, determine to enable the compressed mode for the PS service;

When the code resource utilization rate in the uplink direction is greater than or equal to the second threshold, it is determined to enable the compressed mode for both the PS service and the CS service.

Here, the first threshold value and the second threshold value can be defined according to actual conditions, for example, the first threshold value can be set to 40%, and the second threshold value can be set to 80%. %. Specifically, when the utilization rate of code resources in the uplink direction is less than or equal to 40%, it indicates that the utilization rate of code resources in the uplink direction is in a low-load state, that is, an idle state; when the utilization rate of code resources in the uplink direction is greater than 40% and less than 80%, it indicates that The utilization rate of uplink code resources is in a moderate load state. At this time, uplink code resources can be saved by compressing the uplink accompanying channel resources of PS services; when the utilization rate of uplink code resources is greater than or equal to 80%, it indicates that the uplink code resource utilization rate is In a highly loaded state, it is necessary to enable the compression mode for both the PS service and the CS service.

Specifically, the scheduling the carrier transmitting the concurrent service according to the monitoring situation of the uplink code resource utilization rate and the traffic detection result of the PS service includes:

Specifically, when the resource utilization rate of the uplink code is greater than the first threshold and less than the second threshold, determining to enable the compressed mode for the PS service includes:

By reconfiguring the RAB, PS services below the traffic threshold can independently enter the double frame division state.

Specifically, when the code resource utilization rate in the uplink direction is greater than or equal to the second threshold value, determining to enable the compressed mode for the CS service is: adopting the adaptive multi-rate AMR codec standard lower than the set rate threshold The coding method of the coding rate transmits the CS service;

The determining to enable the compression mode for the PS service when the utilization rate of the code resources in the uplink direction is greater than or equal to the second threshold value includes:

In the current network, the CS service adopts the encoding method of AMR12.2k. AMR coding has 8 kinds of rates, including: 12.2kbit/s, 10.2kbit/s, 7.95kbit/s, 7.4kbit/s, 6.7kbit/s, 5.9kbit/s, 5.15kbit/s, 4.75kbit/s. During the high load period of code resource utilization in the uplink direction, for example, when it is busy, it is possible to use a lower AMR rate to provide higher capacity while ensuring slightly lower voice quality. For example, you can choose AMR7.95k.

When the monitoring module 21 detects that the code resource utilization in the uplink direction is greater than or equal to the second threshold, it determines that the compressed mode is enabled for both the PS service and the CS service.

Preferably, the scheduling module 23 is also used for:

When the system is configured with mixed carriers, schedule the mixed carriers to carry concurrent services.

Specifically, the scheduling module 23 is also used for:

When scheduling concurrent services to R4 carriers, use DPCH to carry concurrent services;

When concurrent services are scheduled to mixed carriers, the DPCH is used to carry the CS services in the concurrent services, and the HS-PDSCH is used to carry the PS services in the concurrent services.

Specifically, the scheduling module 23 is further configured to: when the monitoring module 21 detects that the code resource utilization in the uplink direction is greater than the first threshold and less than the second threshold, by reconfiguring the RAB to lower the traffic Threshold PS services independently enter the double frame division state.

Specifically, the scheduling module 23 is also used for:

When the monitoring module 21 detects that the code resource utilization rate in the uplink direction is greater than or equal to the second threshold value, the CS service is transmitted using a coding method with a coding rate lower than the set rate threshold in the AMR codec standard;

When the monitoring module 21 detects that the resource utilization rate of the uplink code is greater than or equal to the second threshold value, it first compresses the PS services below the flow threshold detected by the detection module 22, and then compresses the PS services below the flow threshold After the PS service is compressed, if the monitoring module 21 detects that the code resource utilization rate in the uplink direction is still greater than or equal to the second threshold, the PS service other than the PS service lower than the traffic threshold is compressed.

In the following, the specific working conditions of the dispatching device according to the embodiment of the present invention are respectively analyzed in three situations: when the uplink code resources in the TD live network are idle, when the load is moderate, and when the load is high.

1. The uplink code resources in the live TD network are idle

When the PS service and the CS service appear concurrently, first, the monitoring module 21 in the dispatching device judges the relationship between the resource utilization rate of the uplink code in the TD live network and the first threshold value n1 at this time;

Here, when the uplink code resource utilization rate is less than or equal to the first threshold value n1, it means that the uplink code resource utilization rate in the TD live network is low, that is, the uplink code resource is in an idle state, and at this time, a low load warning signal can be sent.

Specifically, when the utilization rate of uplink code resources is less than or equal to the first threshold value n1, it indicates that the utilization rate of uplink code resources in the network is low at this time. At this time, it is not necessary to perform compression processing on CS services and PS services, and CS services The business can also use the AMR12.2k encoding method with the highest rate in AMR encoding.

The scheduling module 23 in the scheduling device can decide to schedule the concurrent service to the R4 carrier or the hybrid carrier according to the size of the PS service data packet in the concurrent service detected by the detection module 22 in the scheduling device.

Here, when only the R4 carrier is configured in the cell, the existing DPCH is still used to carry the concurrent service; when a mixed carrier is configured in the cell, the mixed carrier is used to carry the concurrent service. Since the hybrid carrier not only has DPCH resources with two time slots for uplink and downlink, but also has HS-PDSCH time slots for high-speed data transmission, it is very suitable for concurrent service requirements. When hybrid carriers are configured in the system, the transmission efficiency is higher. high. Therefore, the system should adjust the R4 carrier configuration to a hybrid carrier configuration. This adjustment is not the focus of this embodiment of the present invention and will not be expanded.

The scheduling module 23 can judge whether to compress the PS service in the concurrent service when the mixed carrier is used to carry the concurrent service according to the size of the PS service data packet detected by the detection module 22 .

Here, when the mixed carrier carries concurrent services, the HS-PDXCH in the TS3 time slot and the TS4 time slot in the mixed carrier can support the PS service with a large flow rate. At the same time, due to the low utilization rate of uplink code resources, in order to better improve user experience, a mixed mode can be considered, that is, in the uplink direction, CS services and PS services occupy different code channel resources, and in the downlink direction, mixed carriers are used. The HS-PDSCH time slots in DPCH transmit PS services and the DPCH time slots transmit CS services. Fig. 3 is a schematic diagram of carrying concurrent services in mixed mode according to an embodiment of the present invention. As shown in Fig. 3, in the uplink direction, the CS service can occupy the code channel resources of TS1, and the PS service can occupy the code channel resources of TS2; in the downlink direction, use HS-PDSCH time slots transmit PS services, and DPCH time slots transmit CS services.

A piece of code for code channel allocation in mixed mode is as follows:

The above codes show that when concurrent services are carried, the CS service is transmitted in the DPCH time slot, and the PS service is transmitted in the HS-PDSCH time slot, and the related content of the code will not be repeated here.

When the mixed mode is used to transmit concurrent services, the peak rate of the air interface of HS-PDSCH single time slot can reach 560kbps, which is significantly higher than the 128kpbs of the R4 carrier, and the download rate is increased from 384kpbs to 1120kpbs, and the download rate can be increased by 2.9 times. The mode not only improves the concurrency rate of PS services, but also improves user perception.

2. Moderate load on uplink code resource in TD live network

If the monitoring module 21 in the dispatching device judges that the uplink code resource utilization rate in the TD live network is greater than the first threshold value n1 but less than the second threshold value n2, it means that the uplink code resource in the TD live network is now In the moderate load state, the scheduling module 23 in the scheduling device can save uplink code resources by compressing uplink accompanying channel resources of PS services.

Currently, for the case where the R4 carrier bears and transmits services, since the minimum bearer resources are four code channels with SF=16, further compression cannot be performed.

In the embodiment of the present invention, if the detection module 22 detects that the flow of the PS service is lower than the flow threshold, that is, when the size of the PS service data packet in the concurrent service is a small packet, the scheduling module 23 determines that the traffic in the concurrent service carried by the mixed carrier is The PS service performs frame division compression. Here, for the case of using mixed carriers to carry concurrent services, the system can reconfigure the radio access bearer (RAB, Radio Access Bearer), so that the PS service independently enters the double frame division multiplexing state. Fig. 4 is a schematic diagram of frame division multiplexing of CS service and PS service in the uplink direction according to an embodiment of the present invention. Since the frame division multiplexing is performed for PS services with small flows, the transmission of uplink services is not affected. At this time, the download rate of concurrent services can still reach More than 200kb/s can still guarantee user perception. At the same time, the uplink code channel resources only occupy 3 SF=16, and the uplink resource utilization efficiency can be increased by 25%.

3. High load of uplink code resource in TD live network

If the monitoring module 21 in the dispatching device judges that the uplink code resource utilization rate in the TD live network is greater than or equal to the second threshold value n2, it means that the uplink code resource in the TD live network is in a high load state at this time. At this time, The scheduling module 23 in the scheduling device will enable the compressed mode for concurrent services.

Here, the second threshold n2 can be set according to actual needs, for example, it can be set to 80%.

In the following, the CS service and the PS service both adopt the compression mode for the following analysis.

(1) Compress the CS service:

In the current network, the CS service adopts the encoding method of AMR12.2k. AMR coding has 8 kinds of rates, including: 12.2kbit/s, 10.2kbit/s, 7.95kbit/s, 7.4kbit/s, 6.7kbit/s, 5.9kbit/s, 5.15kbit/s, 4.75kbit/s. During periods of high load, such as busy hours, it is possible to use a lower AMR rate to provide greater capacity while ensuring slightly lower voice quality. Figure 5 is a schematic diagram of MOS values corresponding to different encoding methods. It can be seen from Figure 5 that in all cases, the MOS values of AMR-HR are better than FR, only lower than EFR; while CS services use AMR4.75k The encoding method can ensure the MOS value required by the business without affecting the user experience.

(2) Compress PS services:

In the existing business model, the proportion of PS services below the traffic threshold (that is, small traffic PS services) is increasing, such as QQ online, heartbeat information, location information, etc. The uplink and downlink traffic of such small traffic PS services Both are very small, generally less than 8kbps, and it is completely possible to mix the PS service with the small flow rate and the CS service together for transmission in a lower resource mode.

When the monitoring module 21 in the dispatching device detects that the system is under high load, it compresses the concurrent services: first reconfigure the concurrent services of the small-flow PS service and the CS service into the compression mode, and when the uplink and downlink of the CS service and the PS service are up and down 2 SF=16 transmissions in the slot.

In the case of high load, for concurrent services, since PS service downloads are relatively insensitive, the system needs to access more users and services at this time. After the scheduling module 23 compresses the small flow PS services, if the system load is still When it is very high, more PS services other than small flow PS services are also scheduled in compressed mode.

In the case of high load, regardless of whether a traditional R4 carrier or a mixed carrier is used to carry concurrent services, the scheduling module 23 will compress the PS services. Specifically, according to the size of the carried PS service traffic, the PS service can be compressed to 0-8K; for the CS service, you can choose AMR10.2kbit/s, 7.95kbit/s, 7.4kbit/s, 6.7kbit/s, 5.9kbit/s, 5.15kbit/s, 4.75kbit/s and other coding methods, the scheduling module 23 selects the coding method of the CS service according to the compressed size of the PS service, thereby ensuring that the PS service and the CS service can share two Code channel resources.

Figure 6 is a schematic diagram of compressing concurrent services when the R4 carrier is used to carry concurrent services under high load conditions. It can be seen from Figure 6 that for the R4 carrier, when the concurrent services are compressed, the resources occupied by two code channels can be reduced , The utilization efficiency of uplink resources can be increased by 50%, which effectively improves the performance of the system under the condition of high load of uplink code resources.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
