Method, system, device and device for adjusting service quality

The present invention relates to the field of wireless communication technologies, and in particular, to a method, system, device and device for adjusting quality of service (QoS). Background technique

Currently, in order to ensure the quality of the wireless network service of the user, a user level is configured for each user through an Operations Maintenance Center (OMC) background or an Authentication Authorization and Accounting (AAA) server. Each user level corresponds to a corresponding QoS parameter. For the same user, different applications may have multiple QoS flows concurrently. Each flow has a set of QoS requirements. The scheduling factor is a parameter that defines a set of QoS requirements and is used to set different service levels on different flows. The larger the value of the scheduling factor, the higher the level, the larger the packet metric, and the higher the priority that the user is scheduled.

When the user signs the contract, the user level is determined. When the same level of users use the same application, the scheduling priority is also the same, and the scheduling priority does not change with the user's moving state.

However, with the popularity of high-speed railways and highways, more and more users choose high-speed vehicles to travel. When the user moves at a high speed, the wireless loss due to the Dopple effect or the like is also increased, so that the quality of the wireless service experienced by the user is degraded. And when users move at high speed, when they pass through extremely high load areas, such as towns, they use the same scheduling priority, which may not enable users to get better quality of service, for example, may cause video playback. Smooth and so on. Summary of the invention

FIG. 3 is a schematic structural diagram of the apparatus for adjusting the quality of service provided by the present invention. detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments in order to make the present invention. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In order to improve the service quality of high-speed users, the present invention provides a method, system, device and device for adjusting service quality.

FIG. 1 is a process for adjusting the quality of service provided by the present invention, where the process includes the following steps: S101: Receive a call setup request sent by a user.

Specifically, in the embodiment of the present invention, the process of quality of service adjustment is performed in a Base Transceiver Station (BTS), that is, the quality of service adjustment device is placed in the BTS. The user who sends the call setup request is the user's mobile terminal, and the user's mobile terminal is referred to as a user in the present invention for the sake of simplicity.

S102: It is judged whether or not the transmission time of the previous call establishment request of the user is recorded. When the determination result is YES, the process proceeds to step S103, otherwise, the process proceeds to step S107.

S103: determining, according to the moment when the call setup request sent by the user is currently received, and the recorded sending moment of the last call setup request of the user, determining the stay duration of the current cell in the current cell, and setting a request for the last call of the user. Send time to update.

The duration of the stay of the user in the current cell is the time at which the call setup request sent by the user is currently received, and the difference of the recorded call timing of the last call setup request of the user.

S104: Determine whether the retention time of the current cell in the current cell is greater than the retention threshold of the currently-held fan of the user. If the determination result is yes, proceed to step S105; otherwise, proceed to step S106.

Specifically, determining the retention threshold of each carrier fan includes:

According to the configured coverage radius of each carrier fan and the speed of configuring the high-speed mobile user, the retention threshold corresponding to each carrier fan is determined.

S105: Determine that the current user is in a low speed state, and adjust the scheduling priority of the user to a scheduling priority corresponding to the low speed state.

S106: Determine that the current user is in a high speed state, and adjust the scheduling priority of the user to a scheduling priority corresponding to the high speed state. S107: Determine that the user is a new user, and determine that the user is currently in a high-speed state, adjust the scheduling priority of the user to a scheduling priority corresponding to the high-speed state, and record a sending moment of the call setup request of the user.

The above process completes the call setup process of the user. After the call setup of the user is completed, the user in the high-speed state needs to be monitored in real time, the speed state of the user is determined, and the user is scheduled according to the determined speed state of the user. Priority is adjusted.

Specifically, in the embodiment of the present invention, the OMC stores configuration information such as a high-speed QoS switch, each carrier fan angle information, each carrier fan coverage radius information, and a rate threshold. The access network BTS can obtain and save the above configuration information from the OMC. After the BTS obtains the coverage radius information of each carrier fan from the OMC, the retention threshold corresponding to each carrier fan is determined according to the coverage radius of each of the configured fans and the reference speed at which the high speed movement is configured, wherein the configuration The high-speed moving reference speed is the default speed for high-speed movement, and the default can be set to 60km/h (km/h). Specifically, according to StayDurThrhld = CellRadius I DefaulteRate, the retention threshold of each carrier fan is determined, where CellRadius is the configured carrier coverage radius, DefauleRate is the reference speed for configuring the high speed movement, and StayDurThrhld is the retention threshold of the corresponding carrier fan.

The call setup request sent by the user received by the BTS is received from the base station controller (BSC). When the BTS receives the call setup request sent by the user, it determines whether the subscriber is a new subscriber.

The sending moment of each user's last call setup request may be recorded in a user information table, in which the sending moment of the user's last call setup request is recorded, and the call setup of each user is received according to the received call. The requested delivery time is updated. In addition, the information in the user information table is also cleared according to the set period. When the information in the user information table is cleared, the information in the user information table is updated according to the above procedure.

When the information of the transmission time of the call setup request of the user is not recorded in the user information table, the user may be considered as the new user. In the present invention, for new users, in order to effectively guarantee The quality of service of the new user, when determining that the user is a new user, determines that the user is in a high speed state, and adjusts the scheduling priority of the user according to the high speed state.

Specifically, the BTS may arbitrarily set the speed state of the user each time the user is determined to be a new user, and provide the corresponding scheduling priority to the user according to the set speed state. For example, in order to ensure the quality of service of the user, it may be considered that each The user is in a high-speed state, and the corresponding scheduling priority is increased. Alternatively, the user may determine the speed state of the user according to the scheduling priority corresponding to each user when signing the contract. For example, when the user subscribes, the corresponding scheduling priority is compared. When the time is high, the speed state of the user can be regarded as a high speed state; otherwise, the speed state of the user end is determined to be a low speed state.

When determining that the user is not a new user, determining the staying duration of the user in the current cell according to the moment when the current user sends the call setup request and the sending moment of the user's last call setup request recorded in the user information table, and The time of sending the call setup request of the user in the user information table is updated at the moment when the user is currently received the call setup request.

After determining the length of stay of the user in the current cell, the speed state of the user is determined according to the retention threshold of the current fan. When the retention time of the current cell is greater than the retention threshold of the current fan, the user is determined to be in a low-speed state, that is, the scheduling priority of the user should be lower, and the current low-speed state needs to be determined according to the current low-speed state. The scheduling priority of the user. When the retention threshold of the current cell is not greater than the retention threshold of the current fan, the user can be considered to be in a high-speed state, and the scheduling priority of the user is adjusted according to the high-speed state.

After the call setup of the user is completed through the above process, the user who is currently in the high-speed state among the users who have established the call starts the speed determination rule, periodically determines the speed state of the user, and according to the result of the judgment, the user is The scheduling priority is adjusted.

Specifically, in the case of a user who is currently in a high-speed state for the user, the startup speed determination rule advances. The process of judging includes:

According to the set time interval, according to the recorded transmission time of the last call establishment request of the user, it is determined whether the retention time of the current location of the user is greater than the retention threshold of the current fan of the user;

When the retention time of the current cell in the current cell is greater than the retention threshold of the current fan, the user is determined to be in a low-speed state, and the scheduling priority of the user is adjusted to a scheduling priority corresponding to the low-speed state;

When the retention time of the user in the current cell is not greater than the retention threshold of the current fan of the user, according to the Doppler frequency shift and the loop round-trip delay in the set period

(RoundTripDelay, RTD) information, determining the current speed state of the user, and determining whether to adjust the scheduling priority of the user according to the recorded speed state of the user at a previous moment, and updating the speed state of the user.

In order to reduce the number of adjustments of the user scheduling priority, in the present invention, the user's speed state may be recorded in the user information table, for example, the current user is determined to be in a low speed state, and when the user is also in a low speed state at the previous time, It indicates that the scheduling priority of the user is lower at the previous moment. In this case, the scheduling priority of the user does not need to be adjusted. However, when the user is in the high-speed state at the previous moment, the scheduling priority of the user is higher at the previous moment. At this time, since the speed of the user has been reduced, in order to ensure the quality of service of other high-speed users, it is necessary to lower the scheduling priority of the user at this time. And since the speed state of the user is determined at the current time, in order to facilitate the next determination, it is necessary to update the speed state of the user in the user information table by using the speed state of the user determined at the current time.

In the present invention, since the process of determining the speed is performed periodically, in each process of execution, it is required for each user who needs to judge, according to the current time, and the user recorded in the user information table. The sending time of the previous call setup request determines the length of stay of the user in the current cell. When the user stays in the current cell, the duration is greater than the current time of the user. When the retention threshold of the fan is located, it is determined that the user is in a low speed state, and the scheduling priority of the user is adjusted to a scheduling priority corresponding to the low speed state.

When the retention time of the current cell in the current cell is not greater than the retention threshold of the current fan of the user, the speed state of the user cannot be accurately determined at this time, and the rate determination rule needs to be started, that is, according to the set time period. Pule frequency shift and RTD, determine the user's speed status.

Determining a first speed state of the user according to a Doppler shift of the user when determining a speed state of the user according to the Doppler shift and the RTD; and determining, according to the RTD information of the user a second speed state of the user; determining that the user is in a high speed state when at least one of the first speed state and the second speed state is a high speed state; otherwise, determining that the user is in a low speed state.

Specifically, determining, according to the Doppler shift of the user, determining the first speed state of the user includes: according to an average value of Doppler shifts collected during the set time period, and a current location of the configured user The angle of the fan, determining the current speed of the user;

When the determined current user speed is greater than the configured speed threshold, it is determined that the user is in a high speed state, otherwise, the user is determined to be in a low speed state.

Determining the user's speed state according to the Doppler shift in the present invention includes: according to V = (FllFrequencyEstimate/cos(9)) * 0.0247 , where FllFrequencyEstimate is the mean value of the Doppler frequency shift of the set period, Θ The angle of the load fan configured in the OMC background. When the speed of the user is determined, the speed is compared with the configured speed threshold. When the speed is greater than the configured speed threshold, the user is considered to be in a high speed state; otherwise, the user is considered to be in a low speed state.

And determining, according to the RTD information of the user, the second speed state of the user includes: selecting each RTD value in the set time period, selecting a plurality of sets of RTD values according to the set rule, and determining each group of RTD values. Average value

When the average value of each set of RTD values satisfies the set requirement, it is determined that the user is in a high speed state, Otherwise, make sure the user is in the 4th speed state.

Specifically, in the present invention, the set period may be 16 s, and sampling is performed in units of per second, so that it is determined that a plurality of RTD values can be sampled in the period, and the first period is set in the period of the first period. The RTD values in 2, 5-6, 9-10, and 13~14 seconds are averaged to obtain RTD1, RTD2, RTD3, and RTD4. When RTD1<RTD2<RTD3<RTD4 or RTD1>RTD2>RTD3>RTD4 is satisfied between RTD values, it is determined that the user is in a high speed state, otherwise, the user is determined to be in a low speed state.

Since the user determines the first speed state and the second speed state of the user according to the Doppler frequency shift and the RTD value of the user, the first speed state and the second speed state may be combined when determining the final speed state of the user. Joint judgment. This judgment process can be either loose or strict.

Specifically, when the loose request is adopted, when the user is in a high speed state according to the Doppler frequency shift, or when the user is in a high speed state according to the RTD value of the user, the user may be considered to be in a high speed state, that is, according to the user Any method that determines that the user is in a high-speed state can be considered that the user is in a high-speed state, and only determines that the user is in a low-speed state according to the Doppler shift, and determines that the user is in a low-speed state according to the RTD value of the user, and determines the The user is at a low speed. When strict requirements are imposed, the user is considered to be in a high-speed state only when the user is in a high-speed state according to the Doppler shift, and the user is considered to be in a high-speed state when the user is in a high-speed state according to the RTD value of the user; otherwise, the user is considered to be in a low-speed state.

After determining the speed state of the user, it is determined whether to adjust the scheduling priority of the user according to the recorded speed state of the user at a previous moment, and update the speed state of the user.
