Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Acceleration service generally has a certain burstiness characteristic, for example, a user only hopes to obtain stable speed guarantee in a service using time period, other time periods may have no service or low service volume, and in consideration of charging problems, the user generally tends to apply for acceleration when using the service, and release acceleration resources when ending the service.
The 5G QoS acceleration service is mainly implemented by setting up additional GBR bearers for the user. For scheduling at the wireless side, generally, the GBR service will be prioritized over the Non-GBR service, the priority guarantee of the GBR service is mainly reflected in guaranteeing the traffic bit rate GFBR parameter, the basic guarantee of the Non-GBR service is mainly reflected in the minimum bit rate MBR parameter, and the system can schedule preferentially to meet GFBR.
The GBR acceleration service provides high-quality service experience for a part of users, but the wireless resources are limited, the base station can allocate resources for the GBR service preferentially when the resources are called, and excessive GBR service resource allocation can influence the common Non-GBR service and influence the experience of the common users; meanwhile, users using GBR service have excessive access, the users using GBR service also adopt a QoS-based competition algorithm, and even the service experience of the users using GBR service can not be guaranteed when serious, and the user experience is poor. It is therefore necessary to control the access of users to GBR services in order to improve the service experience of users using GBR services and of Non-GBR services.
At present, GBR acceleration service is accelerated by establishing a dedicated GBR bearer link through a core network as long as a user applies legally, and network side equipment does not judge whether a terminal is suitable to be accelerated according to a wireless environment, a resource use condition and the like. Therefore, under the condition that the accelerating user pays through the charging dimension, the service acceleration perception is not ideal, and the complaint problem caused by the non-ideal service acceleration perception is gradually increased; meanwhile, besides complaints of users using the GBR service, common users who do not use the GBR service can not obtain basic network guarantee because resources are preempted; in addition, a user using GBR service may move to a wireless low-level, and there is a case of invalid acceleration.
Fig. 1 is a schematic flow chart of a request processing method according to an embodiment of the present application. Referring to fig. 1, an embodiment of the present application provides a request processing method, including step 101 and step 102.
And step 101, receiving a service acceleration request sent by the terminal.
102, rejecting a service acceleration request of a terminal under the condition that a first condition is met; wherein the first condition comprises at least one of: the network side equipment does not have the capability of accelerating the service corresponding to the newly added service acceleration request; the terminal does not have a service acceleration condition.
Optionally, the network side device first determines whether the terminal has a service acceleration condition, and then determines whether the network side device has the capability of accelerating the service corresponding to the new service acceleration request under the condition that the terminal has the service acceleration condition. Compared with the calculation amount required for judging whether the network side equipment has the capacity of accelerating the service corresponding to the new service acceleration request, the calculation amount required for judging whether the terminal has the service acceleration condition is usually smaller, so the network side equipment can firstly judge whether the terminal has the service acceleration condition, namely firstly judge whether the terminal has the service acceleration condition, and then judge whether the calculation amount is larger after screening, namely judge whether the network side equipment has the capacity of accelerating the service corresponding to the new service acceleration request, and the calculation resource can be effectively saved.
Optionally, the network side device refuses the service acceleration request of the terminal and pushes the following information to the terminal side when the terminal does not have the service acceleration condition: the acceleration fails, and the acceleration is applied after the network is moved to a region with better network quality.
Optionally, the network side device refuses the service acceleration request of the terminal and pushes the following information to the terminal side under the condition that the network side device does not have the capability of newly increasing the acceleration service corresponding to the service acceleration request: failure is accelerated, and the current base station is too much in number, and the user tries again later.
Optionally, the network side device agrees to the service acceleration request of the terminal under other conditions, and pushes the following information to the terminal side: acceleration is successful, and the network environment is kept stable.
In the embodiment of the application, under the condition that the network side equipment does not have the capacity of accelerating the service corresponding to the newly added service accelerating request, if the network side equipment newly adds the accelerating service, the service quality of the network side equipment for other users is reduced; under the condition that the terminal does not have a service acceleration condition, if the network side equipment newly adds an acceleration service to the terminal, invalid acceleration occurs, acceleration resources are wasted, and the service quality of the network side equipment to other users can be reduced. Therefore, in the embodiment of the application, under the condition that the network side equipment does not have the capacity of accelerating the service corresponding to the newly added service acceleration request or the terminal does not have the service acceleration condition, the network side equipment refuses the service acceleration request of the terminal so as to reduce the influence of the newly added service acceleration of the network side equipment on the service quality of the user under the conditions, and effectively improve the user experience.

Referring to fig. 2, an embodiment of the present application provides a request processing method, and steps 202 and 203 are substantially the same as steps 101 and 102, except that step 201 is further included.
Step 201, determining that the network side equipment does not have the capability of accelerating the service corresponding to the newly added service acceleration request under the condition that the number of target resource blocks is larger than the resource admission control threshold; the target number of resource blocks is the total number of Resource Blocks (RBs) used by the network side equipment after the service acceleration request corresponding to the new service acceleration request is added.
Step 202, receiving a service acceleration request sent by a terminal.
Step 203, rejecting the service acceleration request of the terminal under the condition that the first condition is satisfied; wherein the first condition comprises at least one of: the network side equipment does not have the capability of accelerating the service corresponding to the newly added service acceleration request; the terminal does not have a service acceleration condition.
Optionally, the network side device may dynamically configure the resource admission control threshold, specifically, before step 201, further includes the following steps:
s1-1, according to a formula (1), obtaining the number N of RBs used by non-accelerating users which do not use accelerating service and provided by each cell _RB ：
N _RB ＝V _MBR ·N _5QIRB /V _5QI /T/60 (1)
Wherein V is _MBR Is the contracted minimum bit rate MBR, N of non-accelerating users in each cell _5QIRB The number of RBs used by the network side equipment for each cell in T minutes is V _5QI Is the average rate of non-accelerating users in each cell using RB for T minutes, T being the number of minutes that one cycle comprises.
S1-2, acquiring a resource admission control candidate threshold GBR_P' according to a formula (2):
GBR_P’＝max(0，1-N _RB_T /N _RB_A ) (2)
wherein N is _RB_T Is N of each cell _RB Sum of N _RB_A Is the number of RBs currently remaining for each cell.
Alternatively, N _RB_T Is to N of each cell _RB The sum of (2) is rounded up to give the result.
S1-3, determining a resource admission control threshold according to GBR_P' of a plurality of periods.
Optionally, before dynamically configuring the resource admission control threshold, the resource admission control threshold needs to be initialized by the algorithm when the cell is busy.
Specifically, considering mobility of the terminal, each cell should be configured with a resource admission control threshold of GBR service. Counting the number of RBs occupied by each 5G QoS identifier 5QI of each cell and the number of RBs in each cell according to 15-minute granularity data of the network manager, namely data when T=15Average rate V of non-accelerating user usage of RB _5QI And analyzing how many RB numbers should be used for guaranteeing service awareness of non-accelerating users.
Wherein V is _5QI The index of (2) is defined as: the (cell radio link control (Radio Link Control, RLC) service data unit (Service Data Unit, SDU) received byte count-cell user plane RLC SDU tail packet byte count) 8/total duration of service for which the cell RLC layer receives data.
Optionally, S1-3 specifically includes the following two cases:
in the first case, the resource admission control threshold needs to be increased.
Specifically, when the gbr_p ' of M periods is greater than the resource admission control threshold, and the difference between the gbr_p ' of M periods and the resource admission control threshold is greater than the first threshold, and/or the number of failed acceleration service establishment of M periods in each cell is greater than the second threshold, determining an average value of the gbr_p ' of M periods as the resource admission control threshold; wherein M is an integer greater than 1.
Optionally, the number of failure in establishing acceleration service for M periods of each cell is specifically the number of failure in establishing Flow caused by insufficient radio resources corresponding to the acceleration service for M periods of each cell.
Optionally, since the adjustment and enhancement of the resource admission control threshold has a larger influence on the network side device or the base station, the network side device is set to adjust and enhancement of the resource admission control threshold only when all of the following conditions are satisfied at the same time:
1) The gbr_p' for M periods is greater than the resource admission control threshold.
2) The difference between the GBR_P' of the M periods and the resource admission control threshold is larger than the first threshold.
3) The number of acceleration service establishment failures for M consecutive periods of each cell is greater than a second threshold.
Optionally, the value of M is 3, the first threshold value is 5%, and the second threshold value is 0.
It can be understood that after M cycles are passed to determine whether the resource admission control threshold needs to be increased, the cycle counter needs to be cleared to count the cycles again.
In the second case, the resource admission control threshold needs to be adjusted.
Specifically, under the condition that all the GBR_P ' of the N periods are smaller than the resource admission control threshold and the difference value between the GBR_P ' of the N periods and the resource admission control threshold is larger than a third threshold, determining the average value of the GBR_P ' of the N periods as the resource admission control threshold; wherein N is an integer greater than 1.
Optionally, the value of N is 1, and the value of the third threshold is 5%.
It can be understood that after N cycles are passed to determine whether the resource admission control threshold needs to be increased, the cycle counter needs to be cleared to count the cycles again.
Optionally, the network side device acquires the target number of resource blocks, specifically, before step 201, the method further includes the following steps:
s2-1, according to the formula (3), obtaining V _REQUEST Corresponding safe equivalent RB number N _safe ：
Wherein V is _REQUEST Is the guaranteed traffic bit rate GFBR, V corresponding to the service acceleration request _f Is the rate at which the terminal is not accelerating, N _frb Is that the terminal reaches V _f Number of RBs used, Q _f Is that the terminal reaches V _f Modulation order used, Q i Is the order of the ith modulation mode, P i The duty ratio of the i-th modulation scheme is k, which is the number of modulation schemes.
In particular, regarding terminal reaching V _f The modulation order Q used _f For example, Q is a modulation scheme using quadrature phase shift keying (Quadrature Phase Shift Keying, QPSK) _f =2; modulation scheme using 16 quadrature amplitude modulation (Quadrature Amplitude Modulation, QAM), Q _f ＝4。
It will be appreciated that Q i Is cell network management statisticsThe order of the ith modulation mode, P i The duty ratio of the ith modulation mode counted by the cell network manager is k, and k is the number of all the modulation modes counted by the cell network manager.
S2-2, according to the formula (4), obtaining the number N of the target resource blocks _GBR_P ：
N _GBR_P ＝N _GBR_E +N _safe (4)
Wherein N is _GBR_E Is the RB number currently used by the network side device to accelerate traffic.
Specifically, if N _GBR_P The RB number corresponding to the resource admission control threshold is larger than the resource admission control threshold, and rejecting the service acceleration request of the terminal; if N _GBR_P And if the number of RBs corresponding to the resource admission control threshold is smaller than or equal to the number of RBs corresponding to the resource admission control threshold, agreeing to the service acceleration request of the terminal.
In the embodiment of the application, the network side equipment can dynamically adjust the resource admission control threshold according to the wireless network condition so as to adapt to the current wireless network environment, thereby further improving the user experience.

Referring to fig. 3, an embodiment of the present application provides a request processing method, in which a service acceleration request is an uplink service acceleration request, and steps 303 and 304 are substantially the same as steps 101 and 102, except that steps 301 and 302 are further included.
Step 301, according to formula (5), obtaining the maximum speed V to which the terminal can accelerate _Pr ：
V _Pr ＝V _f ·P _f /P _u (5)
Wherein V is _f Is the rate at which the terminal is not accelerating, P _f Is the maximum power of the terminal, P _u Is the power that the terminal has currently used.
Step 302, at V _Pr Less than V _REQUEST Under the condition of (1), determining that the terminal does not have a service acceleration condition; wherein V is _REQUEST Is the guaranteed traffic bit rate GFBR corresponding to the traffic acceleration request.

Optionally, the network side device may first determine whether the terminal power has a margin according to the power margin reported by the terminal. If the power of the terminal has no allowance, the terminal is in the scene of uplink weak coverage or interference, at this time, if the network side equipment reallocates more RB resources, only the power of each RB is reduced, the demodulation process is more difficult, and further the uplink rate is not guaranteed, at this time, the network side equipment shall reject the service acceleration request of the terminal.
If the power of the terminal has a margin, the network side device judges whether the power margin can support the speed up to which the service acceleration request is applied, and the specific judgment is shown in step 301 and step 302.
Maximum rate V to which acceleration can be achieved at the terminal _Pr V smaller than the corresponding service acceleration request _REQUEST Under the current wireless environment and the use condition of terminal power, the terminal expects to accelerate to a speed smaller than the speed applied by the service acceleration request sent by the terminal, the user perceives the non-ideal, and the service acceleration request should be refused;
maximum rate V to which acceleration can be achieved at the terminal _Pr Is larger than V corresponding to the service acceleration request _REQUEST Under the current wireless environment and the using condition of the terminal power, the terminal predicts the speed of accelerating to the speed applied by the service accelerating request sent by the terminal, and can agree with the service accelerating request, or further judge whether the network side equipment has the capability of accelerating the service corresponding to the service accelerating request.
In the embodiment of the application, the network side equipment judges whether the terminal has the service acceleration condition or not under the condition that the service acceleration request is an uplink service acceleration request, and refuses the service acceleration request of the terminal under the condition that the terminal does not have the service acceleration condition, thereby effectively improving the user experience.

Referring to fig. 4, an embodiment of the present application provides a request processing method, in which a service acceleration request is a downlink service acceleration request, and steps 402 and 403 are substantially the same as steps 101 and 102, except that the method further includes step 401.

FIG. 5 is a flowchart of a request processing method according to an embodiment of the present application. Referring to fig. 5, an embodiment of the present application provides a request processing method, including the following steps:
step 501, the base station periodically adjusts a resource admission control threshold.
Step 502, after receiving the service acceleration request, the base station synchronously acquires information such as wireless environment and acceleration rate of the terminal.
Specifically, the terminal sends a service acceleration request to the network side device, and in this embodiment, sends information such as power information of the terminal, a modulation mode of the terminal, wireless environment information, a current perceived rate, RB resource usage conditions, GBR acceleration rate requirements, and the like, simultaneously.
The power information of the terminal includes, for example, a power headroom of the terminal, the modulation mode of the terminal includes, for example, 256QAM and 64QAM, the wireless environment information includes, for example, a field strength and an interference condition of the terminal, the current perceived rate includes, for example, a current network rate value of the terminal, the RB resource usage condition includes, for example, a RB number corresponding to the current perceived rate used by the terminal, and the GBR acceleration rate requirement includes, for example, a GFBR parameter value corresponding to an acceleration service of the current 5G QoS service acceleration request.
Step 503, the base station determines whether the terminal has a service acceleration condition.
Step 504, the base station judges whether the base station has the capability of newly adding the acceleration service corresponding to the service acceleration request.
Specifically, since the terminal is usually mobile in the wireless environment, the modulation mode adopted when the terminal sends the service acceleration request may be different from the modulation mode adopted when the terminal moves to the wireless weak field, and generally the terminal will adopt a lower-order modulation mode when the terminal moves to the wireless weak field, which may use more RB numbers, and these extra RB numbers also can preempt Non-GBR service to affect the user perception, so that the terminal must be estimated according to a certain cell model when accessing, and the number of RBs possibly used by the terminal is equivalently converted to improve the stability of the system.
According to the granularity data of network management 15 minutes, the duty ratio of each modulation mode of each cell is counted, the wireless environment model of the cell is represented, and the safe equivalent RB resource value is analyzed based on mathematical expectation to be used as the target resource block number N _safe 。
The coding ratios corresponding to different modulation modes are as follows:
the QPSK coding ratio, the index is defined as the ratio of the number of Terabytes (TBs) modulated with QPSK to the total number of TBs transmitted during the statistical period T.
The 16QAM coding ratio, the index is defined as the ratio of the number of TBs modulated with 16QAM to the total number of TBs transmitted during the statistical period T.
Step 505, the base station agrees or refuses the service acceleration request of the terminal, and sends a push message to the terminal.
