Technical Field

Background

With the development of communication technology, the appearance of wireless technology provides greater bandwidth for users, and has the advantages of very fast deployment speed and low comprehensive cost, and operators in many countries and regions utilize wireless technology to meet the network access requirements of common families.

Currently, a home using a wireless network generally accesses the wireless network through a Customer Premises Equipment (CPE), and in general, a home using a wireless broadband access deploys a CPE. However, in some countries with low income, many households cannot bear the required fee of the CPE, so how to share the CPE with multiple households to perform wireless access and charge and authenticate each household separately becomes a problem to be solved urgently in order to further reduce the purchase cost of the CPE.

In order to solve the above problems, the methods adopted in the prior art are as follows:

different families can respectively authenticate and charge through the CPE and a Broadband Remote Access Server (BRAS). However, for the base station side, to ensure the fairness scheduling principle, the resources (including the size and the sequence) scheduled by the base station for each CPE are basically consistent, and in this scenario, the resources of some CPEs are excessive, and the resources of some CPEs are insufficient.

Obviously, the prior art has the problems of low resource utilization rate and poor use experience of part of users due to the imperfect resource scheduling mode.

Fig. 2 is a schematic structural diagram of a base station 100. In fig. 2:

the base station 100 comprises at least one processor 101, at least one memory 102, at least one transceiver 103, at least one network interface 104 and one or more antennas 105. The processor 101, memory 102, transceiver 103 and network interface 104 are connected, for example, by a bus. The antenna 105 is connected to the transceiver 103. The network interface 104 is used to connect the base station to other communication devices via a communication link. In the embodiment of the present application, the connection may include various interfaces, transmission lines, buses, and the like, which is not limited in this embodiment.

The processor in the embodiment of the present application, for example, the processor 101, may include at least one of the following types: a general-purpose Central Processing Unit (CPU), a Digital Signal Processor (DSP), a microprocessor, an Application-specific integrated Circuit (ASIC), a Microcontroller (MCU), a Field Programmable Gate Array (FPGA), or an integrated Circuit for implementing logical operations. For example, the processor 101 may be a single-core (single-CPU) processor or a multi-core (multi-CPU) processor. The at least one processor 101 may be integrated in one chip or located on a plurality of different chips.

The memory in the embodiments of the present application, for example, the memory 102, may include at least one of the following types: read-only memory (ROM) or other types of static memory devices that may store static information and instructions, Random Access Memory (RAM) or other types of dynamic memory devices that may store information and instructions, and Electrically erasable programmable read-only memory (EEPROM). In some scenarios, the memory may also be, but is not limited to, a compact disk-read-only memory (CD-ROM) or other optical disk storage, optical disk storage (including compact disk, laser disk, optical disk, digital versatile disk, blu-ray disk, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer.

The digital baseband signal and the digital intermediate frequency signal may be collectively referred to as a digital signal.

In order to make those skilled in the art better understand the technical solution in the embodiment of the present application, first, a brief description is given to a solution in the prior art in which a user accesses a network through a CPE, with reference to fig. 1.

Specifically, in the prior art, the CPE and the BRAS establish a two-layer tunneling protocol (L an 2tunneling protocol, &lttt translation = L "&gtt L &ltt/t &gtt2TP) tunnel, and the specific details of establishing the L2 TP tunnel are not related to the present application and are not described herein again.

Subsequently, the user can dial to BRAS through Point-to-Point Protocol over ethernet (PPPoE), authentication and accounting are completed through AAA server, and BRAS allocates IP for the user. Fig. 2 is a schematic diagram illustrating a communication flow between a subscriber and a BRAS, where in fig. 2:

1) the user initiates a PADI message to the CPE and starts the PPPoE access process.

2) CPE sends PADO message to user range.

3) The user initiates a PADR request to the CPE in response to the response.

4) The CPE generates a session ID and sends it to the subscriber via the PADS.

5) The L CP negotiation of PPP is performed between the user and the CPE to establish link layer communication.

6) The user sends a Password Authentication Protocol (PAP) request to the CPE, where the request carries a user name and a Password (the Password is in a plaintext form).

7) The CPE interacts with the BRAS over the L2 TP tunnel and establishes a session.

8) The CPE performs L CP negotiation with the BRAS.

9) The CPE initiates a user authentication request to the BRAS, where the user authentication request carries a user name and a password, so that the BRAS interacts with the AAA and is authenticated by the AAA server (this process is not shown in the figure).

10) And the BRAS returns the authentication result to the CPE.

11) The CPE sends a PAP authentication confirmation to the user.

12) The CPE carries out NCP negotiation (such as IPCP and IPv6CP) negotiation, and acquires parameters such as a planned IP address through the BRAS.

13) The user and the CPE carry out NCP negotiation to obtain parameters such as an IP address.

Then, the user can perform data interaction with the base station through the CPE based on the acquired IP address.

In the data interaction process, each CPE is a single channel for the base station side, that is, the CPE can be regarded as a terminal under the base station regardless of how many users access the CPE. Therefore, the base station treats the CPE as the same as other User Equipment (UE) (e.g., mobile terminal) accessing the base station during the resource scheduling process, that is, the base station schedules the CPE as the same resource as other UE based on the fairness principle, so that fairness cannot be maintained among a plurality of users accessing the CPE when the air interface resource is insufficient.

For example, the following steps are carried out: in the prior art, it is assumed that an operator promises to limit a speed of 10Mbps for a single user, and a minimum rate of 4Mbps can be guaranteed in busy hours, and a base station provides air interface resources with equal scheduling opportunities for UEs (including CPE and other devices) in each access cell (single carrier) based on fairness, and can guarantee a UE rate of a near point (it should be noted that the near point refers to a signal-to-noise ratio greater than or equal to 17dBi, that is, spectral efficiency is above a certain level) to be above 45Mbps when a Space Division Multiplexing (SDM) technology is used. Thus, for each CPE, the requirements of only a maximum of 11 service-full users can be met while guaranteeing the lowest rate.

Taking CPE1 in fig. 1 as an example, user 1, user 2, and user 3 currently accessing all can reach a rate of 10Mbps, and at this time, the base station detects that the rate of CPE1 reaches 30Mbps, that is, CPE1 has 10Mbps resources available, and if there are a plurality of new users accessing CPE1, the rate of the new users will be reduced to less than 10 Mbps. While for CPE2, its downstream access to user 4, user 5, and user 6 can still meet their full-load rate requirements.

Obviously, the prior art has the problems of low resource utilization rate and poor use experience of part of users.

In view of the above problems, an embodiment of the present application provides a resource scheduling method to effectively improve the utilization rate of resources and the user experience.

In conjunction with the above described communication system, as shown in fig. 1, a specific embodiment of the present application is described below:

scene one

Referring to fig. 1, as shown in fig. 3, a schematic flow chart of a resource scheduling method in the embodiment of the present application is shown, where in fig. 3:

specifically, in the embodiment of the present application, a user may access a base station through a CPE, and perform data transmission with the base station through the CPE. Taking user 1 in fig. 1 as an example:

1) user 1 initiates a PPPoE negotiation to the BRAS via the CPE.

2) After PPPoE negotiation is completed, entering PPP authentication negotiation phase.

3) In the PPP authentication negotiation phase, the BRAS initiates authentication to the AAA server.

4) And after the authentication is successful, carrying out an IPCP negotiation stage, and acquiring the allocated IP address from the BRAS equipment by the CPE equipment.

5) The user 1 can perform data transmission with the base station through the CPE and the IP address.

The access procedure from the user 2 to the user 9 is the same as the above steps, and is not described herein again. The details of the user's access to the wireless network may refer to the steps in the prior art embodiments described above.

In the embodiment of the present application, after the user accesses the base station through the CPE, the steps in fig. 3 may be performed. Specifically, the method comprises the following steps:

step 101, a base station acquires equipment information of a CPE.

Specifically, in the embodiments of the present application, the device information includes, but is not limited to: the method comprises the steps of spectrum efficiency, information of the number of users accessing the CPE, information of the type of service currently processed by each user accessing the CPE and/or transmission rate information, wherein the transmission rate information comprises a target transmission rate and an actual transmission rate, and the target transmission rate is the sum of expected transmissions of each user accessing the CPE.

Optionally, in one embodiment, the information about the number of users accessing the CPE and the expected transmission rate of each user accessing the CPE are sent to the base station by the CPE. The CPE may send information carrying the number of users and/or the expected transmission rate of each user to the base station through private signaling. In one embodiment, the private signaling may be implemented by extending existing signaling. For example, the following steps are carried out: the CPE may carry the number information of the users and/or the information of the expected transmission rate of each user in a reserved field in Radio Resource Control (RRC) signaling. Alternatively, the CPE may also carry the number information of the users and/or the information of the expected transmission rate of each user in a Medium Access Control sublayer Control unit (MAC CE), which is not limited in this application. In this embodiment, after the CPE sends the information of the number of users and/or the information of the expected transmission rate of each user to the base station, the base station needs to return response information to inform that the CPE has successfully received the information, otherwise, the CPE repeatedly sends the information under the condition that the CPE does not receive the response information within a predetermined time period to ensure that the base station successfully receives the information. And in one embodiment, the CPE monitors the user access condition of the CPE, and when a new user accesses or an old user goes offline, the CPE sends the quantity information of all users currently accessing the CPE and the expected transmission rate to the base station, so that the base station can acquire the device information of the CPE side in time.

Optionally, in another embodiment, the spectral efficiency, the actual transmission rate, and the like included in the device information are monitored by the base station, that is, the base station may obtain information such as the current spectral efficiency and the actual transmission rate of the CPE by direct measurement. The measurement method of the spectrum efficiency and the actual transmission rate may refer to the scheme in the embodiment in the prior art, and is not described in detail in this application. And, in one embodiment, the base station may obtain device information such as spectral efficiency, actual transmission rate, etc. in real time and periodically filter, smooth, and update the policy. The filtering window (it should be noted that the filtering window is a period size for the base station to perform filtering smoothing processing on the signal) and the update period may be automatically adjusted according to an actual situation (in an embodiment of the present application, a rule for the base station to automatically adjust the filtering window and the update period may be set according to a load state of the base station or other factors, and may be set according to the actual situation, which is not limited by the present application), so that a suitable countermeasure for a state change of the CPE may be selected in time.

Optionally, in another embodiment, the base station may cache the acquired device information to the local, so as to adjust the corresponding scheduling priority based on the device information of each CPE in the subsequent step. Or, the base station may only cache the device information acquired last time, that is, the base station deletes the device information of the CPE acquired last time after acquiring the current device information of the CPE every time, so as to save resource occupation.

And step 102, the base station adjusts the scheduling priority of the CPE based on the equipment information and the adjustment strategy.

Specifically, the wireless air interface resource of the base station is shared, that is, multiple users (including the CPE and/or other terminal devices) share the air interface resource of the base station, but when there are too many access users, network congestion will occur, so that the above-mentioned problem will occur, that is, multiple users under the CPE cannot obtain the same experience, and the traffic of some users is smaller or much smaller than that of other users under the same CPE and/or users under other CPEs. The base station in the embodiment of the application can adjust the scheduling priority of each CPE based on the acquired equipment information according to a preset adjustment strategy so as to realize the dynamic control of the flow of the CPE, thereby meeting the real-time requirements of the CPE.

It should be noted that the scheduling priority in this embodiment of the application is used to indicate a scheduling order when the base station schedules resources for the CPEs, where the higher the scheduling priority is, the earlier the scheduling order corresponding to the CPEs is. For example, the following steps are carried out: the scheduling priorities of CPE1, CPE2, and CPE3 are: CPE1> CPE2> CPE 3. When the base station schedules the resources according to the priority, it preferentially schedules the resources required by the CPE1, for example: the base station currently has 100ms time domain resources, the base station allocates 70ms of the time domain resources to the CPE1 based on the requirement of the CPE1, and allocates 30ms of the time domain resources to the CPE2 based on the requirement of the CPE2, so that the CPE3 has an opportunity to obtain scheduled resources when waiting for the next round of scheduling. Therefore, for CPE1, because its scheduling priority is higher, the base station performs resource scheduling for CPE1 according to its required resources preferentially, and for CPE3 with the lowest scheduling priority, the base station performs resource scheduling for CPE3 in a manner of buffering data, that is, at the next scheduling time later, so that data corresponding to CPE3 is transmitted temporarily, and the transmission delay is increased, thereby reducing the actual transmission rate of CPE 3.

Optionally, in an embodiment, the scheduling policy may include: and adjusting the scheduling priority strategy of the CPE according to the quantity information. The details will be set forth in the second scenario.

Optionally, in an embodiment, the scheduling policy may include: and adjusting the scheduling priority of the CPE according to the spectrum efficiency. The specific details will be set forth in detail in scenario three.

Optionally, in an embodiment, the scheduling policy may include: and adjusting the scheduling priority of the CPE according to the transmission rate. The details will be set forth in scene four.

Optionally, in an embodiment, the scheduling policy may include: and adjusting the scheduling priority strategy of the CPE according to the type information of the service. The details will be set forth in scene five.

And 103, the base station performs resource scheduling for the CPE based on the adjusted scheduling priority.

Specifically, in the embodiment of the present application, after the base station adjusts the scheduling priority of each CPE according to the scheduling policy, the base station performs resource scheduling for each CPE based on the adjusted scheduling priority. Specifically, in the scheduling process, the base station may obtain the current scheduling priority of each CPE, and perform the scheduling according to the scheduling priority, and then perform resource scheduling on the CPEs in sequence based on the scheduling queue.

For example, the following steps are carried out: if the current scheduling priority level of CPE1 is: 3 (where a larger number represents a lower scheduling priority), the scheduling priority level of CPE2 is: 1, CPE3 has a scheduling priority level of 2. Then, in the resource scheduling process, the base station queues the CPEs according to the scheduling priority of each CPE, where the queue is: CPE2, CPE3, CPE 1. Then, the base station first schedules the resources required by the CPE2, that is, allocates the resources to which the base station belongs to the CPE2 according to the requirements of the CPE 2. Then, the base station allocates resources to CPE3 and CPE1 in the order in which CPE3 and CPE1 are in the queue, respectively.

Obviously, in the embodiment of the present application, the CPE with higher scheduling priority can preferentially obtain the required resources. For example, the following steps are carried out: if the current flow of the CPE3 just meets 3 users (user 7, user 8, and user 9) accessed under the CPE3, newly accessing the user 10 at this time, and the expected transmission rate required by the user 10 is 5 Mbps; in this scenario, the CPE3 needs to report the current number of users and the expected transmission rate of the users to the base station, and the base station increases the scheduling priority of the CPE3 to preferentially schedule resources for the CPE3, and the size of the resources scheduled for the CPE3 meets the current resource demand of the CPE 3. For the CPE1 with a lower scheduling priority, the base station may perform resource scheduling for the other CPEs after completing the resource scheduling for the other CPEs according to the scheduling priority. Or, in an embodiment, the base station may also not perform resource scheduling for the CPE1, so that the data of the CPE1 is buffered, or the data of the CPE1 is directly discarded, so that the data is sent to the CPE1 when resource scheduling is performed next time, so that the TCP window of the user on the CPE1 is shrunk, so as to reduce the speed of the data packet sent by the base station to the CPE1, thereby achieving the purpose of flow control.

Further, in the embodiment of the present application, the CPE may further perform flow control on the user accessing the CPE, so that all users (including the user accessing the base station and the user accessing the CPE) under the base station achieve consistent flow. For example, the following steps are carried out: after the base station side performs flow control on each CPE accessing the base station by using a scheduling policy, each CPE may acquire a corresponding scheduling resource according to a desired flow required by each CPE, for example, with the CPE1, at this time, after the CPE1 acquires the required resource, the flow of the CPE1 is increased, and the user 1 newly accessing the CPE3 may reach a desired transmission rate, if the transmission rate of the user 2 under the CPE3 is too large (for example, exceeds a preset threshold, which may be set according to a requirement, for example, exceeds 50% of other users), the CPE1 may further perform flow control on the user with too large flow, that is, the user 2. The flow control method can be as follows: CPE3 buffers, or drops, user 2's data, thereby causing the TCP window for user 2 to shrink to reduce the incoming packet rate (i.e., the rate at which packets are sent by the base station to user 2), i.e., to reduce user 2's traffic so that user 1's rate is not reduced by the lack of air interface resources. Fig. 4 is a schematic flow chart of traffic control under the CPE. Based on the steps, the fairness of the use experience of all users under the base station (including the users directly accessing the base station and the users accessing the base station through the CPE) can be further ensured.

To sum up, in the technical solution in this embodiment of the application, the base station may adjust the scheduling priority of the CPE based on an adjustment policy, thereby implementing traffic control on the CPE, and implementing resource fairness among users under multiple CPEs.

Referring to fig. 1, as shown in fig. 5, a schematic flow chart of a resource scheduling method in the embodiment of the present application is shown, where in fig. 5:

in step 201, the CPE sends information on the number of users accessing the CPE to the base station.

Specifically, in the embodiment of the present application, the CPE monitors the number information of the users accessing the CPE in real time, that is, when the users of the CPE change (including the new user accessing and the old user offline), the CPE sends the current number information of the users to the base station.

Optionally, in an embodiment, the CPE may send the number information of the users to the base station by means of extended signaling. As previously described, the extended signaling may be: and expanding the MAC CE or the RRC signaling, that is, carrying the number information of the users through a specified field of the MAC CE or the RRC signaling, so as to inform the base station CPE of the number of the currently accessed users.

Step 202, the base station adjusts the scheduling priority of the CPE according to the adjustment strategy based on the user number information.

Specifically, in the embodiment of the present application, the adjusting policy may include: and when the user quantity information exceeds a first threshold value, the scheduling priority of the CPE is increased to a preset priority. In the embodiments of the present application, the first threshold may be set in a variety of ways:

in an embodiment, the first threshold may be a preset constant threshold, and in this embodiment, if the number of users of any CPE exceeds the first threshold, it is determined that the number of users of the CPE is too large, that is, the scheduling priority of the CPE may be increased, and a specific increased value may be determined according to a difference between the number of users accessing the CPE and the first threshold. For example, the following steps are carried out: if the number of the users accessing the CPE is 15 and the first threshold is 10, the difference is 5, and the base station may determine to increase the scheduling priority of the current CPE by 2 levels, that is, if the scheduling priority of the CPE is 5, the scheduling priority of the CPE is adjusted to 3 (as described above, the smaller the value is, the higher the scheduling priority is, where the adjusted priority is the preset priority in the embodiment of the present application).

In another embodiment, the first threshold may be an average of the number of users accessing the CPE. That is, the number of users in each CPE in the base station is averaged to be the first threshold. In this embodiment, if the number of users under the CPE exceeds the first threshold, it may be determined that the number of users under the CPE exceeds the average value, that is, the number of users under the CPE is large, that is, the scheduling priority of the CPE may be increased. The specifically adjusted value may also be referenced to the difference between the CPE and the first threshold.

In yet another embodiment, the scheduling priority of each CPE may also be reset based on the number of users under each CPE. For example, the following steps are carried out: if the number of users accessing the CPE1 is 10, the number of users accessing the CPE2 is 3, and the number of users accessing the CPE3 is 5, then the scheduling priority order is: CPE1> CPE3> CPE 2.

That is to say, in this embodiment, the higher the number of access users is, the higher the scheduling priority obtained by the CPE is, so that fairness in use experience of all users (including the user directly accessing the base station and the user accessing through the CPE) accessing the base station in a scenario of the CPE with multiple users can be achieved.

And step 203, the base station performs resource scheduling for the CPE based on the adjusted scheduling priority.

This step can be referred to as step 103, which is not described herein.

Scene three

Referring to fig. 1, as shown in fig. 6, a schematic flow chart of a resource scheduling method in the embodiment of the present application is shown, where in fig. 6:

in step 301, the base station obtains the spectrum efficiency of the CPE.

Specifically, in the embodiment of the present application, the base station may periodically obtain the spectrum efficiency of the CPE. The specific obtaining manner may refer to a technical scheme in an embodiment of the prior art, and is not described in detail herein. In this embodiment, the base station periodically triggers the time, and detects the spectrum efficiency of the CPE, wherein the detection period may be set according to actual requirements. For example: the detection period may be dynamic, that is, the detection period may be dynamically set according to the loading condition of the base station or the spectrum efficiency change condition of the CPE. For example: if the first detection period and the second detection period measure that the spectrum efficiency of each CPE has no obvious change, the scheduling priorities of the CPEs set in the first detection period and the second detection period are basically the same, so that the base station can delay the triggering time of the third detection period, namely, the period is increased. And if the base station detects that the frequency spectrum efficiency of each CPE changes in the fifth detection period and correspondingly adjusts the scheduling priority of each CPE, the base station can shorten the detection period, thereby realizing the dynamic setting of the detection period. In one embodiment, the detection period may also be dynamically set according to a load condition of the base station, in other embodiments, the detection period may be a constant value, and the specific setting may be set according to an actual situation, which is not limited in this application.

Step 302, the base station adjusts the scheduling priority of the CPE according to the scheduling policy based on the spectrum efficiency of the CPE.

Specifically, in the embodiment of the present application, the spectrum efficiency refers to how good the current transmission quality of the CPE is. Therefore, in the scheduling policy in the embodiment of the present application, for the CPEs whose spectrum efficiency is lower than the second threshold, the base station may lower the scheduling priority corresponding to the CPEs, so that the resources of the base station are inclined toward the CPEs with better spectrum efficiency, thereby further improving the utilization rate of the resources.

Optionally, in an embodiment, for the CPEs with spectrum efficiency lower than the second threshold, the base station may determine a specific value of the scheduling priority that needs to be adjusted (i.e., determine the preset priority) according to a difference between the spectrum efficiency and the second threshold. For example: if the difference between the spectrum efficiency and the second threshold is large, the difference between the number of stages of the scheduling priorities adjusted by the base station for the corresponding CPEs is large. Otherwise, the smaller the stage difference of the adjusted scheduling priorities.

In this embodiment, the setting of the second threshold value also has a plurality of ways: in one embodiment, the second threshold may be a predetermined constant threshold. In another embodiment, the second threshold may also be an average of the spectral efficiency of each CPE.

Optionally, in the embodiment of the present application, the base station may further perform real-time statistics on spectral efficiencies of all the access terminals, and reset the scheduling priorities of the CPEs according to the spectral efficiencies of the CPEs. Specifically, the base stations are arranged in the order of decreasing spectral efficiency of each CPE, and the scheduling priorities of the CPEs are set based on the order in the queue, that is, the scheduling priority of the CPE at the head of the queue is the highest, whereas the scheduling priority of the CPE at the end of the queue is the lowest.

That is to say, in this embodiment, the higher the spectrum efficiency is, the higher the scheduling priority obtained by the CPE is, and the lower the spectrum efficiency is, the lower the scheduling priority obtained by the CPE is, so as to implement the rational allocation of resources, so as to further improve the resource utilization rate.

And step 303, the base station performs resource scheduling for the CPE based on the adjusted scheduling priority.

This step can be referred to as step 103, which is not described herein.

Scene four

Referring to fig. 1, as shown in fig. 7, a schematic flow chart of a resource scheduling method in the embodiment of the present application is shown, where in fig. 7:

in step 401, the base station obtains the transmission rate of the CPE.

Specifically, in the embodiment of the present application, the transmission rate may include: an actual transmission rate of the CPE and a target transmission rate of the CPE. The actual transmission rate of the CPE can be measured by the base station, and the target transmission rate of the CPE can be reported to the base station by the CPE. In an embodiment of the present application, the target transmission rate is a sum of expected transmission rates of users accessing the CPE, in one embodiment, the CPE may directly send the target transmission rate to the base station, and in another embodiment, the CPE may also report the number of users accessing the CPE and the expected transmission rate of each user to the base station, and calculate the target transmission rate of the base station, which is not limited in this application.

Optionally, in an embodiment, the target transmission rate or the expected transmission rate of each user sent by the CPE to the base station may also be sent to the base station by means of extended signaling. As mentioned above, the extended signaling may be: and expanding the MAC CE or the RRC signaling, that is, carrying the above information through a designated field of the MAC CE or the RRC signaling.

Step 402, the base station adjusts the scheduling priority of the CPE according to an adjustment strategy based on the transmission rate.

Specifically, in the embodiment of the present application, the base station may determine the scheduling priority of each CPE based on a difference between an actual transmission rate and a target transmission rate of each CPE. The adjustment strategy comprises the following steps: if the actual transmission rate is less than the target transmission rate, the scheduling priority is increased; if the actual transmission rate is continuously greater than or equal to the target transmission rate within the preset time length, the scheduling priority is adjusted to be low.

Optionally, in an embodiment, the expected transmission rate of each user may be the lowest limit transmission rate, that is, for user 1, the expected lowest limit transmission rate is 7Mbps, and then the rate obtained by user 1 from the base station and/or CPE should theoretically be not less than 7 Mbps.

Optionally, in another embodiment, the expected transmission rate of each user may also be an optimal transmission rate, that is, for user 1, the service processed by user 1 can be kept in a good operation mode at a rate of 8Mbps (below 8Mbps, the user experience is poor, above 8Mbps, the service operates better, but the resource utilization rate is low), and the rate acquired by user 1 from the base station and/or the CPE should theoretically be not less than 8 Mbps.

In the embodiment of the application, if the actual transmission rate of the CPE is less than the target transmission rate, the base station determines to increase the scheduling priority of the CPE based on the scheduling policy. The specific value of the increased scheduling priority can be adjusted according to the difference between the actual transmission rate and the target transmission rate. That is, the larger the difference between the actual transmission rate and the target transmission rate, the larger the value of the scheduling priority adjustment. In one embodiment, the CPEs may also be arranged in descending order based on a difference between an actual transmission rate and a target transmission rate of each CPE, where the base station sets the highest scheduling priority for the CPE arranged at the head of the queue, and sets the scheduling priorities for the CPEs in the queue in turn. In another embodiment, the base station may further extract all CPEs with actual transmission rates greater than the target transmission rate, and sort the CPEs in the order from small to large according to the actual transmission rates, where the base station sets the highest scheduling priority for the CPE that is ranked at the head of the queue, and sets the scheduling priorities for the CPEs in the queue in turn.

And, in the embodiment of the present application, if the actual transmission rate of the CPE is continuously greater than or equal to the target transmission rate for a predetermined time (which may be set according to actual requirements), the scheduling priority of the CPE is adjusted to be low, so as to limit the traffic of the CPE of this type, and reduce the rate of the CPE, so that resources are inclined to the CPE which fails to reach the target transmission rate, and the fairness of the user experience among users is further improved.

That is to say, in this embodiment, the actual transmission rate is less than the target transmission rate, and the larger the difference between the actual transmission rate and the target transmission rate, the higher the scheduling priority corresponding to the CPE is, so that fairness in use experience of all users (including a user directly accessing the base station and a user accessing through the CPE) accessing the base station in a scenario of the CPE with multiple users can be achieved.

Step 403, the base station performs resource scheduling for the CPE based on the adjusted scheduling priority.

This step can be referred to as step 103, which is not described herein.

Scene five

Referring to fig. 1, as shown in fig. 8, a schematic flow chart of a resource scheduling method in the embodiment of the present application is shown, where in fig. 8:

step 501, the CPE sends to the base station the type information of the currently processed service of each user accessing the CPE.

Specifically, in the embodiment of the present application, the CPE may send, to the base station, the type information of the service currently processed by each user of the CPE at a triggering time of a cycle (the cycle may be set according to actual requirements).

Optionally, in an embodiment, the CPE may send the type information of the traffic to the base station by means of extended signaling. As previously described, the extended signaling may be: extended MAC CE or extended RRC signaling.

Step 502, the base station adjusts the scheduling priority of the CPE according to the adjustment strategy based on the type information of the service.

Specifically, in this embodiment, the scheduling policy may include: and increasing the scheduling priority of the CPE corresponding to the user with the type information of the currently processed service as the specified type information. The specified type information may be one or more specific types of services, such as: voice traffic, video traffic, and/or download traffic.

Optionally, in one embodiment, the specified type information may also be sorted, for example: and sequencing according to the importance degree of the service types, wherein the specified service type A, the specified service type B and the specified service type C are obtained. Then, when adjusting the scheduling priority of the CPEs, the base station may determine the scheduling priority according to a condition of a specified service type included in the service currently processed by the user of each CPE.

For example, the following steps are carried out: if user 1 and user 2 under CPE1 are both handling the specified traffic type A, user 5 under CPE2 is handling the specified traffic type B, and user 9 under CPE3 is handling the specified traffic type C. Then, the base station determines that the scheduling priority order of each CPE is arranged from large to small as follows: CPE1> CPE2> CPE 3.

That is, in this embodiment, the resources on the base station side are inclined toward the CPE to which the user handling the higher-level service belongs, so that fairness of usage experience of all users accessing the base station (including the user directly accessing the base station and the user accessing through the CPE) in a scenario of the multi-user CPE is achieved.

Step 503, the base station performs resource scheduling for the CPE based on the adjusted scheduling priority.

This step can be referred to as step 103, which is not described herein.

In addition, in an embodiment of the present application, the adjustment manners of the scheduling priorities in the above scenarios may also be combined with each other. For example, the following steps are carried out:

in one embodiment, the adjustment policy may be: based on the spectrum efficiency, for a plurality of CPEs with higher spectrum efficiency, the scheduling priority can be further adjusted according to the number of users of the CPEs. For example: if the spectral efficiency of CPE1 and the spectral efficiency of CPE2 are higher, the spectral efficiency of CPE3 is lower, where the number of users of CPE3 is much greater than the number of users of CPE1 and CPE2, and in this scenario, the base station does not tilt the resources to CPE3 with a larger number of users, but raises the scheduling priorities of CPE1 and CPE2, and tilts the resources to the CPE with better spectral efficiency. Therefore, the problem that the whole resource utilization rate of the base station is reduced due to the fact that the resources are inclined to the CPE with more users and poor spectrum efficiency is solved, and further, if the number of the users of the CPE1 is larger than that of the CPE2, the base station sets the scheduling priority of the CPE1 to be larger than that of the CPE2, so that the resources are inclined to the CPE with good spectrum efficiency and large number of the users, and the resource utilization rate is further improved.

In another embodiment, the adjustment policy may further be: based on the number of users, for a plurality of CPEs with a larger number of users, the scheduling priority may be further adjusted according to the type information of the service currently processed by each user of the CPE. For example: for CPEs 1 and 2 with a larger number of users (i.e., the number of users of CPEs 1 and 2 both exceed the first threshold, where the number of users of CPE1 may be greater than the number of users of CPE2, and the number of users of CPE1 may also be less than or equal to the number of users of CPE 2), the base station may further determine the scheduling priorities of CPE1 and CPE2 according to the types of traffic handled by the users of CPE1 and CPE 2.

In another embodiment, the scheduling policy may be: based on the number of users, for a plurality of CPEs with a larger number of users, the scheduling priority may be further adjusted according to the transmission rate of the CPE. For example: for CPEs 1 and 2 with a larger number of users (i.e., the number of users of CPEs 1 and 2 both exceed the first threshold, where the number of users of CPE1 may be greater than the number of users of CPE2, and the number of users of CPE1 may also be less than or equal to the number of users of CPE 2), the base station may further determine the scheduling priorities of CPE1 and CPE2 according to the transmission rates of CPE1 and CPE2, for example: if the number of users of CPE1 is greater than CPE2 and the number of users of CPE1 and CPE2 are both greater than the first threshold, the base station may further detect a difference between the actual transmission rate and the target transmission rate of CPE1 and CPE2, and if the actual transmission rate of CPE1 is greater than the target transmission rate and the difference is 10Mbps, the actual transmission rate of CPE2 is greater than the target transmission rate and the difference is 5Mbps, the base station may set the scheduling priority of CPE1 to be greater than the scheduling priority of CPE 2.

It should be noted that, when the indexes (the indexes are parameters such as the number of users, the transmission rate, and the spectrum efficiency) in the scheduling policy are combined with each other to determine the scheduling priority, each index may be converted into different weight coefficients (it should be noted that, a conversion relationship between the indexes and the weight coefficients, that is, a degree of influence of the indexes on the scheduling priority, or on a result obtained after resource scheduling based on the scheduling priority, may be determined by sufficient simulation or test of an operator in different scenarios). Accordingly, the base station may perform weighting processing on the scheduling priority adjustment of each user. For example: when the spectral efficiency is combined with the number of users, it may be determined that the spectral efficiency has a greater impact on the scheduling priority. For example, the following steps are carried out: if the CPE1 has a large number of users and low spectral efficiency, the base station will give priority to the amount of spectral efficiency, and then determine to adjust the priority according to the number of users. For the scenario that other indexes are combined with each other to determine the scheduling priority, an operator can set the scheduling policy at the base station side according to actual requirements, which is not described in detail herein.
