Description

Communication method, device and system

Technical Field

Embodiments of the present application relate to the field of communications technologies, and in particular, to a communication method, device, and system.

Background

With the continued development of narrowband internet of things (narrow band internet of things, NB-IoT), NB-IoT has been widely used in a number of industries. The current NB-IoT may support quality of service (quality of service, qoS) control functions for user traffic. But in its implementation, it is common to directly multiplex the QoS control policies of long term evolution (long term evolution, LTE).

The NB-IoT is different from the LTE corresponding service types, the QoS requirements of the different service types are different, and the corresponding QoS parameter ranges are different. For example, LTE may be generally applied to services such as video transmission, voice call, etc., the delay range in the corresponding QoS parameters may be 10ms-30ms, while NB-IoT may be generally applied to services such as smart street lamps, shared bicycle, and smart water meter, smart electricity meter, etc., and the delay range in the corresponding QoS may be 100ms-10 months. Therefore, the control QoS policy of LTE is not instructive to the actual application of NB-IoT, and cannot really serve the purpose of guaranteeing the QoS of NB-IoT traffic.

Disclosure of Invention

The application provides a communication method, a device and a system, which can ensure QoS requirements of different services.

The application adopts the following technical scheme:

in a first aspect, the present application provides a communication method, which may be applied to a core network device, the method may include: acquiring a quality of service QoS parameter of a first service supported by core network equipment; the QoS parameters include traffic frequency; and sending the QoS parameter to the access network equipment to instruct the access network equipment to allocate network resources for the first service according to the QoS parameter.

By the communication method provided by the embodiment of the application, the service frequency of the service is added in the QoS parameter, so that the access network equipment can obtain the resource allocation frequency corresponding to the service frequency of the service, and network resources are allocated for the service by the resource allocation frequency; thereby guaranteeing the QoS of the service.

With reference to the first aspect, in one possible implementation manner, the QoS parameter may further include one or more of the following: traffic, delay, packet loss rate. In the possible implementation manner, the user can configure the content included in the QoS parameters according to the actual requirements, so that the diversity of the QoS parameters is improved, and the QoS of the service is further ensured.

With reference to the first aspect or one of the foregoing possible implementation manners, in another possible implementation manner, the QoS parameter includes a delay and/or a packet loss rate, and the method may further include: acquiring N service indexes of a first service in a preset time; wherein, the service index comprises time delay and/or packet loss rate; n is greater than 1; comparing the N service indexes with the corresponding service indexes in the QoS parameters to obtain M service indexes meeting the QoS parameters; m is greater than or equal to 1; and adjusting the service frequency of the first service according to M service indexes meeting the QoS parameters. In this possible implementation, the QoS parameters and indicators of the service may be kept synchronized, thereby further guaranteeing the QoS of the service.

With reference to the first aspect or any one of the foregoing possible implementation manners, in another possible implementation manner, adjusting a service frequency of the first service according to M service indexes that meet QoS parameters may include: determining that M is greater than a first threshold; the traffic frequency of the first traffic is reduced. In this possible implementation manner, when the number of times that the service index of the first service satisfies the QoS parameter of the first service is greater than the first threshold, the service frequency in the QoS parameter of the first service may be reduced appropriately, so as to ensure the QoS of the service.

With reference to the first aspect or any one of the foregoing possible implementation manners, in another possible implementation manner, adjusting a service frequency of the first service according to M service indexes that meet QoS parameters may include: determining that M is less than a second threshold; the traffic frequency of the first traffic is increased. In this possible implementation manner, when the number of times that the service index of the first service satisfies the QoS parameter of the first service is smaller than the second threshold, the service frequency in the QoS parameter of the first service may be increased appropriately, so as to ensure the QoS of the service.

With reference to the first aspect or any one of the foregoing possible implementation manners, in another possible implementation manner, the method may further include: acquiring QoS parameters corresponding to the adjusted service frequency of the first service; and sending the QoS parameters corresponding to the adjusted service frequency of the first service to the access network equipment so as to instruct the access network equipment to allocate network resources for the first service according to the QoS parameters corresponding to the adjusted service frequency of the first service. In this possible implementation manner, the access network device may adjust the resource allocation frequency of the first service according to the service index of the first service, so as to further guarantee QoS of the service.

In a second aspect, the present application provides another communication method, which may be applied to an access network device, the method may comprise: receiving QoS parameters of a first service sent by core network equipment; the first service is any service supported by core network equipment and access network equipment; the QoS parameters include traffic frequency; determining the resource allocation frequency of the first service according to the service frequency of the first service; and allocating network resources for the first service in the allocable network resources according to the resource allocation frequency.

With reference to the second aspect, in one possible implementation manner, determining, according to a service frequency of the first service, a resource allocation frequency of the first service may include: acquiring service frequency ranges of a plurality of queues; determining a queue of which the service frequency range comprises the service frequency of the first service as a queue to which the first service belongs; acquiring a resource allocation frequency corresponding to a queue to which a first service belongs, and taking the resource allocation frequency as the resource allocation frequency of the first service; wherein the resource allocation frequency of the first service is equal to or less than the service frequency of the first service. In the possible implementation manner, the queue to which the service belongs can be determined according to the service frequency of the service, and then the resource allocation frequency corresponding to the queue is used as the resource allocation frequency of the first service, so that the flexibility of determining the resource allocation frequency of the first service is improved. Typically, the service resource allocation frequency is equal to the service frequency, although the service resource allocation frequency may be smaller than the service frequency.

With reference to the second aspect, in one possible implementation manner, the QoS parameter further includes a traffic volume, and allocating network resources for the first service among the allocable network resources may include: acquiring the traffic of a first service; among the allocable network resources, a network resource allocated for the first service among the allocable network resources according to the traffic. In this possible implementation manner, when the traffic of the first service is a fixed value, network resources meeting the traffic can be allocated to the first service, so that waste of network resources can be avoided, and the utilization rate of the network resources can be improved.

With reference to the second aspect or one of the foregoing possible implementation manners, in another possible implementation manner, in an allocable network resource, the network resource allocated for the first service in the allocable network resource according to the traffic may include: if the traffic is less than or equal to the allocable network resources; among the allocable network resources, network resources meeting the traffic are allocated for the first service; if the traffic is greater than the allocable network resources; in the allocable network resources, allocating network resources meeting the traffic of the service with other traffic smaller than the allocable network resources at the resource allocation frequency of the first service; if the traffic volume of all the services under the resource allocation frequency of the first service is larger than the allocable network resources; among the allocatable network resources, the allocatable network resource is allocated for the first service. In this possible implementation manner, different allocation manners are configured according to different relationships between the traffic volume of the first service and the current allocable network resources, so that allocation of the network resources can be more reasonable.

Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only 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.

In the embodiments of the present application, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same item or similar items having substantially the same function and effect. It will be appreciated by those of skill in the art that the words "first," "second," and the like do not limit the amount and order of execution, and that the words "first," "second," and the like do not necessarily differ. The technical features described in the first and second descriptions are not sequential or in order of magnitude.

In embodiments of the application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion that may be readily understood.

In the description of the present application, unless otherwise indicated, "/" means that the objects associated in tandem are in a "or" relationship, e.g., A/B may represent A or B; the "and/or" in the present application is merely an association relationship describing the association object, and indicates that three relationships may exist, for example, a and/or B may indicate: there are three cases, a alone, a and B together, and B alone, wherein a, B may be singular or plural. Also, in the description of the present application, unless otherwise indicated, "a plurality" means two or more than two. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, or c may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or plural.

In the embodiment of the present application, at least one may also be described as one or more, and a plurality may be two, three, four or more, and the present application is not limited thereto.

For ease of understanding, the technical terms to which the present application relates will be explained first.

A service may refer to an application running on a user equipment with some specific requirements. Wherein one or more applications may be running on one user device. For example, the user equipment 1 may comprise a shared bicycle service; the user device 2 may include a smart water meter service and a smart electricity meter service.

Network resources may refer to resources in a network used to transmit data. For example, the network resource may be a radio air interface resource, or a bandwidth resource.

QoS parameters may refer to parameters for guaranteeing the quality of service of a user. Wherein the QoS parameters may include one or more of the following: service frequency, traffic volume, delay, packet loss rate.

The service index may refer to an index for measuring the service quality of a user. Wherein, the traffic index may include a delay and/or a packet loss rate.

Traffic frequency may refer to the frequency of communication between traffic and other devices. Wherein the frequency of one service may comprise an uplink service frequency and/or a downlink service frequency. For example, the uplink traffic frequency of one service may be 10 seconds (s)/times.

Traffic may refer to the size of data transmitted when communicating between the traffic and other devices. Wherein the traffic of one service may comprise uplink traffic and/or downlink traffic. For example, the upstream traffic of one service may be 1 Kilobyte (KB).

The service QoS guarantee schemes of LTE and NB-IoT in the prior art are first briefly described.

Wherein the LTE or NB-IoT network may include one or more terminal devices, access network devices, LTE or NB-IoT core network devices, and so forth; one or more services are run on one terminal device; the access network device comprises one or more queues, and one queue corresponds to the service with the same quality grade or priority.

The service QoS guarantee scheme for LTE is: when the service 1 (for example, video service) needs to be operated on the terminal equipment 1, the LTE core network equipment establishes a link of the service 1 on the access network and the terminal, searches a QoS parameter (information such as quality class identifier (QoS class identifier, QCI), priority, delay, packet loss rate, etc.) value of the service 1 in a QoS service printing table of the LTE, and then sends the QoS parameter of the service 1 to the access network equipment.

The access network device receives the QoS parameters of the service 1, and places the service 1 in a queue of the QCI6 according to the QCI value (QCI 6) in the QoS parameters. Likewise, the access network device may receive QoS parameters of a plurality of services, and place the plurality of services in queues of corresponding QCI according to QCI in the QoS parameters of each service. Wherein, the smaller the QCI value of one queue, the higher the queue scheduling priority; the higher the traffic priority in one queue, the more prioritized the scheduling.

Then the access network device schedules the service in different queues according to proportional fair (proportional fairness, PF) scheduling algorithm or Round-Robin (RR) algorithm, and when the service is scheduled to one queue, network resources are allocated to the service in each queue according to the order of the service priority in the queue from high to low. After the network resource is allocated to the service 1, the service 1 transmits data with the access network equipment through the network resource so as to ensure the QoS of the service 1.

The traffic QoS provisioning scheme for NB-IoT is: when the service 2 (for example, the intelligent water meter service) needs to be operated on the terminal equipment 2, the NB-IoT core network equipment establishes a link of the service 1 on the access network and the terminal, and searches the QoS parameters of the service 2 in the QoS service printing table of the multiplexed LTE, and because the range of the information such as time delay, packet loss rate and the like in the QoS service printing table of the multiplexed LTE cannot be matched with the range of the information such as time delay, packet loss rate and the like of the intelligent water meter service, only the priority (for example, priority 6) of the service 2 can be obtained, and then the priority of the service 2 is sent to the access network equipment.

The access network device receives the priority of the service 2 and places the service 2 in a queue of the priority 6 according to the priority 6. Likewise, the access network device receives priorities of a plurality of services, and places each service in a corresponding queue according to the priority of each service.

The access network device then schedules the traffic in the different queues according to a proportional fair (proportional fairness, PF) scheduling algorithm or a Round-Robin (RR) algorithm, etc., and allocates network resources for the hit traffic in the best possible way. After the network resource is allocated to the service 2, the service 2 transmits data with the access network device through the network resource so as to ensure the QoS of the service 2.

As can be seen from the above QoS guarantee scheme of NB-IoT, since the traffic types of NB-IoT and LTE are greatly different, qoS requirements of different traffic are different, and the types of corresponding QoS parameters and the ranges of QoS parameters are different. Therefore, the QoS guarantee scheme of the QoS traffic printing table of the LTE is directly multiplexed, and the traffic QoS of NB-IoT cannot be guaranteed.

For example, in the NB-IoT QoS provisioning scheme, if service 2 has a higher priority than service 3, but service 3 (e.g., a shared bicycle service) has a higher latency requirement, in this case, the access network device may preferentially allocate network resources to service 2 and then allocate network resources to service 3, which may result in failing to meet the latency requirement in QoS of service 3.

In NB-IoT networks, because the traffic types included in NB-IoT networks are quite rich, qoS requirements differ between different traffic types, e.g., the frequency at which data is sent (traffic frequency) differs between different traffic; the traffic frequency of the intelligent traffic light service may be 1 time per second, and the traffic frequency of the intelligent water meter service may be 1 time per month. Based on this, the embodiment of the application provides a communication method, in which the service frequency of the service is added in the QoS parameter, so that the access network device can obtain the resource allocation frequency corresponding to the service frequency of the service, and allocate network resources for the service with the resource allocation frequency; thereby guaranteeing the QoS of the service.

In order to facilitate understanding of the implementation process of the scheme in the embodiment of the present application, first, a network architecture in the embodiment of the present application will be described. The communication method in the embodiment of the application can be applied to the following network architecture.

It should be noted that, the network architecture and the scenario are for more clearly describing the technical solution of the embodiment of the present application, and do not constitute a limitation to the technical solution provided by the embodiment of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided by the embodiment of the present application is equally applicable to similar architectures and scenarios.

Acquiring a quality of service QoS parameter of a first service supported by core network equipment; the QoS parameters include traffic frequency; and sending the QoS parameter to the access network equipment to instruct the access network equipment to allocate network resources for the first service according to the QoS parameter.

In another possible implementation, when the communication apparatus is an access network device; alternatively, the communication device is deployed at an access network apparatus. The processor 21 performs the following functions by running or executing software programs and/or modules stored in the memory 22 and invoking data stored in the memory 22:

receiving QoS parameters of a first service sent by core network equipment; the first service is any service supported by core network equipment and access network equipment; the QoS parameters include traffic frequency; determining the resource allocation frequency of the first service according to the service frequency of the first service; and allocating network resources for the first service in the allocable network resources according to the resource allocation frequency.

In another aspect, an embodiment of the present application provides a communication method that may be applied to the communication device 20 shown in fig. 2.

It should be noted that, the communication method provided by the embodiment of the present application may be used to allocate network resources to one or more services running on the terminal device, so as to ensure QoS of the services. When allocating network resources to each service, the method in the embodiment of the present application may be adopted, and the process will be described by taking the first service as an example, and the processing of other services may refer to the implementation process of the first service, which will not be described in detail.

Specifically, fig. 3 is a flowchart of a communication method according to an embodiment of the present application, and as shown in fig. 3, the method may include:

s301, the core network equipment acquires the QoS parameters of the first service.

The first service is any service supported by the core network equipment and the access network equipment.

It should be noted that, the core network device configures QoS parameters of a plurality of services in advance.

The embodiment of the application does not limit the time for configuring the QoS parameters of a plurality of services for the core network equipment. For example, the configuration opportunity may be at a design stage of the communication apparatus or at a use stage of the communication apparatus and before the communication method of the embodiment of the present application is performed.

For example, when the mobile equipment identification code (international mobile equipment identity, IMEI) of the terminal equipment is imported, service requirement confirmation can be performed, one or more service properties operated under the mobile equipment are analyzed, and service QoS parameters corresponding to the properties are formulated for each service.

In one possible implementation, the QoS parameters may include traffic frequency.

The traffic frequencies may include, among other things, uplink traffic frequencies and/or downlink traffic frequencies. Specifically, the uplink service frequency may be the same as the downlink service frequency, or the uplink service frequency may be different from the downlink service frequency.

Illustratively, the QoS parameters of the configured plurality of services may be as shown in table 1.

TABLE 1

It should be noted that table 1 is only an exemplary format for recording QoS parameters of a plurality of services, and should not be construed as a specific limitation on the recording format.

In another possible implementation, the QoS parameters may further include one or more of the following: traffic, delay, packet loss rate.

Wherein the traffic may comprise uplink traffic and/or downlink traffic. In particular, the uplink traffic may be the same as the downlink traffic, or the uplink traffic may be different from the downlink traffic.

Illustratively, the QoS parameters of the configured plurality of services may be as shown in table 2.

TABLE 2

Wherein 0 represents this traffic demand uncertainty; t is a theoretical value of the data quantity of single transmission.

It should be noted that table 2 is only an exemplary format for recording QoS parameters of a plurality of services, and should not be construed as a specific limitation on the recording format.

Specifically, S301 may be implemented as: the core network equipment firstly acquires the first service, and then searches the QoS parameters of the first service in the recorded QoS parameters of a plurality of services.

When the core network device acquires the first service, the first service can be determined by means of service identification, service name or serial number of the terminal device.

Corresponding to the two implementation manners, the QoS parameter of the first service acquired in S301 may include a service frequency of the first service; or may further comprise one or more of the following: traffic of the first service, time delay of the first service, and packet loss rate of the first service.

S302, the core network device sends the QoS parameter to the access network device to instruct the access network device to allocate network resources for the first service according to the QoS parameter.

In a possible implementation manner, the access network device and the core network device are specified in advance through a protocol, and the access network device is instructed to allocate network resources for the service according to the received QoS parameters of the service by transmitting the QoS parameters of the service between the access network device and the core network device. S302 may be implemented as: the core network device sends the QoS parameter of the first service to the access network device, and the access network device is instructed to allocate network resources for the first service according to the QoS parameter of the first service through the QoS parameter.

In another possible implementation manner, the access network device and the core network device are specified in advance through a protocol, and the access network device is instructed to allocate network resources for the service according to the received QoS parameters of the service by transmitting allocation indication information and the QoS parameters of the service between the access network device and the core network device. S302 may be implemented as: the core network device sends QoS parameters of the first service and allocation indication information to the access network device so as to indicate the access network device to allocate network resources for the first service according to the QoS parameters of the first service.

S303, the access network equipment receives the QoS parameters of the first service sent by the core network equipment.

Wherein, the QoS parameter of the first service received by the access network device in S303, that is, the QoS parameter of the first service sent by the core network in S302.

S304, the access network equipment determines the resource allocation frequency of the first service according to the service frequency of the first service.

Specifically, implementation of S304 may include, but is not limited to, implementation 1 or implementation 2 described below.

In implementation mode 1, an access network device determines a resource allocation frequency corresponding to a service frequency of a first service as the resource allocation frequency of the first service.

The access network device configures corresponding resource allocation frequencies for different service frequencies in advance, and stores the configuration information. In implementation mode 1, the access network device acquires the configuration information, and searches for a resource allocation frequency corresponding to the service frequency of the first service as the resource allocation frequency of the first service.

It should be noted that, if the first service includes an uplink service frequency or a downlink service frequency, the resource allocation frequency of the first service is a resource allocation frequency corresponding to the uplink service frequency or the downlink service frequency; if the first service includes an uplink service frequency and a downlink service frequency, the resource allocation frequency of the first service is the resource allocation frequency corresponding to the uplink service frequency and the downlink service frequency.

In implementation 2, the access network device determines, according to the service frequency of the first service, a queue to which the first service belongs, and then uses the resource allocation frequency of the queue as the resource allocation frequency of the first service.

Wherein the resource allocation frequency of the first service is equal to or less than the service frequency of the first service.

Illustratively, a plurality of queues are preconfigured in the access network device, each queue corresponds to a different service frequency range, and one queue comprises one or more services of which the service frequency belongs to the service frequency range; each queue corresponds to a different frequency of resource allocation.

The information of the plurality of queues configured by the exemplary access network device may be as shown in table 3.

TABLE 3 Table 3

It should be noted that table 3 is merely illustrative of one form of recording information of a plurality of queues, and should not constitute a specific limitation on the recording form.

In particular, implementation 2 may include, but is not limited to, schemes a through C described below.

The service frequency of the scheme a, the first service may include an uplink service frequency of the first service.

Specifically, the access network device obtains the uplink service frequency of the first service included in the QoS parameter of the first service received in S303, searches a queue corresponding to the uplink service frequency range including the uplink service frequency of the first service in the information of the plurality of queues, and uses the queue as a queue to which the first service belongs, where the resource allocation frequency corresponding to the queue is used as the resource allocation frequency of the first service.

The service frequency of the scheme B, the first service may include a downlink service frequency of the first service.

Specifically, the access network device obtains the downlink service frequency of the first service included in the QoS parameter of the first service received in S303, searches a queue corresponding to the downlink service frequency range including the downlink service frequency of the first service in the information of the plurality of queues, and uses the queue as a queue to which the first service belongs, where the resource allocation frequency corresponding to the queue is used as the resource allocation frequency of the first service.

The service frequency of the scheme C, the first service may include an uplink service frequency of the first service and a downlink service frequency of the first service.

Specifically, the access network device obtains the uplink service frequency and the downlink service frequency of the first service included in the QoS parameter of the first service received in S303, searches the queues whose corresponding uplink service frequency range includes the uplink service frequency of the first service in the information of the plurality of queues, and the queues whose corresponding downlink service frequency range includes the downlink service frequency of the first service, and uses the two queues as queues to which the first service belongs, where the resource allocation frequencies corresponding to the two queues are used as the resource allocation frequency of the first service.

It should be noted that, the resource allocation frequency corresponding to each queue may be configured as a fixed value; or a dynamic adjustment value; or otherwise.

Optionally, to avoid that the services of the queues are hit simultaneously at the same time, that is, the resource allocation frequency of the services is met at the same time, the resource allocation rates of the queues may be appropriately adjusted, so as to avoid the hit simultaneously.

Alternatively, when multiple services are hit at the same time, the multiple services may be reordered randomly or according to information such as priority, and then network resources may be allocated to the multiple services in sequence.

S305, the access network equipment allocates network resources for the first service in the allocable network resources according to the resource allocation frequency.

Specifically, S305 may include, but is not limited to, implementation 1 to implementation 4 described below.

When the QoS parameter of the first service does not include the traffic, the access network equipment allocates network resources for the first service in an allocatable mode according to the resource allocation frequency. In other words, the access network device allocates all allocable network resources to the first traffic.

In a possible implementation manner, when the QoS parameter of the first service includes an uplink service frequency of the first service, the access network device allocates uplink network resources for the first service in a manner as far as possible in the allocable uplink network resources according to the resource allocation frequency.

In another possible implementation manner, when the QoS parameter of the first service includes a downlink service frequency of the first service, the access network device allocates downlink network resources for the first service in a manner as far as possible in the allocable downlink network resources according to the resource allocation frequency.

In still another possible implementation manner, when the QoS parameter of the first service includes an uplink service frequency and a downlink service frequency of the first service, the access network device allocates the uplink network resource and the downlink network resource to the first service in a manner as far as possible in the allocable uplink network resource and the allocable downlink network resource according to the resource allocation frequency.

When the traffic volume sent or received by the first service is not a fixed value, or when the traffic volume sent or received by the first service is a fixed value, but the QoS parameter sent to the access network device does not include the traffic volume, the method in implementation 1 may be used to allocate network resources to the first service. When the traffic volume sent or received by the first service is a fixed value and the QoS parameter sent to the access network device includes the traffic volume, any one of the methods from implementation 2 to implementation 4 may be adopted to allocate network resources for the first service.

The access network equipment judges the relation between the traffic of the first service and the allocable network resource; if the traffic volume of the first service is less than or equal to the current allocable network resource of the access network device, the method of implementation 2 may be adopted to allocate the network resource for the first service; if the traffic volume of the first service is greater than the allocable network resource and the traffic volume of other services existing at the resource allocation frequency of the first service is less than the allocable network resource, the method of implementation 3 may be adopted to allocate the network resource for the first service; if the traffic volume of the first service is greater than the allocable network resource and the traffic volume of other services not existing at the resource allocation frequency of the first service is less than the allocable network resource, the method of implementation 4 may be used to allocate the network resource for the first service.

When judging the relation between the traffic of the first service and the allocable network resources, the access network equipment acquires the uplink traffic and/or the downlink traffic of the first service, and judges whether the uplink traffic and/or the downlink traffic of the first service is greater than the current allocable uplink network resources and/or allocable downlink network resources.

And 2, the access network equipment allocates network resources meeting the traffic volume for the first service in the allocable network resources according to the resource allocation frequency.

In a possible implementation manner, when the QoS parameter of the first service includes the uplink traffic of the first service, the access network device allocates, for the first service, an uplink network resource that can satisfy the uplink traffic of the first service in the allocable uplink network resources at the resource allocation frequency.

In another possible implementation manner, when the QoS parameter of the first service includes the downlink traffic of the first service, the access network device allocates, for the first service, a downlink network resource that can satisfy the downlink traffic of the first service in the allocable uplink network resources at the resource allocation frequency.

In still another possible implementation manner, when the QoS parameter of the first service includes an uplink traffic of the first service and a downlink traffic of the first service, the access network device allocates, in the allocable uplink network resource, an uplink network resource that can satisfy the uplink traffic of the first service to the first service, and allocates, in the allocable downlink network resource, a downlink network resource that can satisfy the downlink traffic of the first service, in the resource allocation frequency.

The realization 3, the access network equipment allocates the network resources meeting the traffic volume for the service with the resource allocation frequency, wherein the other traffic volume of the network resources which are smaller than the allocable network resources in the allocable network resources under the resource allocation frequency of the first service.

Specifically, the access network device allocates network resources to the service with other traffic less than the allocable network resources under the resource allocation frequency of the first service, and then allocates network resources to the first service when the first traffic is less than the allocable network resources.

And 4, the access network equipment allocates the allocable network resource for the first service in the allocable network resource according to the resource allocation frequency.

In other words, the access network device uses the allocable network resources entirely for the first traffic.

Furthermore, the communication method provided by the embodiment of the application can also monitor the QoS of the first service at the access network side and adjust the QoS parameter of the first service according to the monitoring result. As shown in fig. 4, the process may include, but is not limited to, S306 to S308 described below.

It should be noted that, the user may configure the timing of monitoring and adjusting the QoS of the service according to the actual requirement, which is not particularly limited in the embodiment of the present application.

For example, the QoS of traffic may be monitored and adjusted periodically or when network resources are limited.

S306, the core network equipment acquires N service indexes of the first service in a preset time.

Wherein N is greater than 1.

The traffic index of the first traffic may include one or more of: time delay and packet loss rate.

Specifically, the network side log of the core network records the service index of each service. S306 may be implemented as: the core network equipment invokes the service indexes of each service recorded in the network side log of the core network, and traverses the log to search N time delays and/or N packet loss rates of the first service within preset time to serve as N indexes of the first service.

S307, the core network device compares the N service indexes with the corresponding service indexes in the QoS parameters to obtain M service indexes meeting the QoS parameters.

Wherein M is greater than or equal to 1.

Specifically, S307 may be implemented as: the core network device compares N time delays and/or N packet loss rates in the N service indexes with the time delays and/or the packet loss rates of the corresponding service indexes in the QoS parameters respectively, and considers the service indexes as the service indexes meeting the QoS parameters of the first service if the time delays and/or the packet loss rates of the service indexes are smaller than or equal to the time delays and/or the packet loss rates in the QoS parameters.

It should be noted that, if the delay and the packet loss rate of the service indicator are both smaller than or equal to the delay and/or the packet loss rate of the QoS parameter, the service indicator is considered to satisfy the QoS parameter of the first service.

S308, the core network device adjusts the service frequency of the first service according to M service indexes meeting the QoS parameters.

Specifically, the core network device firstly judges whether M is greater than a first threshold value, and if M is greater than the first threshold value, the core network device judges whether M is greater than the first threshold value; reducing the service frequency of the first service; if M is smaller than the first threshold, judging whether M is smaller than the second threshold; if M is smaller than the second threshold value, increasing the service frequency of the first service; and if M is smaller than the first threshold value and larger than the second threshold value, not adjusting the service frequency of the first service.

It should be noted that, the processing method when M is equal to the first threshold value or when M is equal to the first threshold value may be configured according to the actual situation, which is not particularly limited in the embodiment of the present application.

For example, if M is equal to the first threshold, the traffic frequency of the first traffic may be reduced, or the frequency of the first traffic may not be adjusted.

For another example, if M is equal to the second threshold, the traffic frequency of the first traffic may or may not be increased.

Wherein the first threshold is greater than the second threshold.

The user may configure the first threshold and the second threshold according to the actual requirement, which is not specifically limited in the embodiment of the present application.

The M service indexes meeting the QoS parameters may be continuous meeting the QoS parameters, or discontinuous meeting the QoS parameters.

It should be noted that, the granularity of the increased or decreased service frequency of the first service may be configured according to the actual situation, which is not specifically limited in the embodiment of the present application. Wherein the granularity of the increase or decrease may be a fixed empirical value or a dynamic adjustment value or otherwise.

S309, the core network equipment acquires the QoS parameters corresponding to the adjusted service frequency of the first service.

In S309, the core network device acquires a QoS parameter corresponding to the adjusted service frequency of the first service, that is, in S308, the QoS parameter of the first service after the service frequency is adjusted.

And S310, the core network equipment sends QoS parameters corresponding to the adjusted service frequency of the first service to the access network equipment so as to instruct the access network equipment to allocate network resources for the first service according to the QoS parameters corresponding to the adjusted service frequency of the first service.

Specifically, the implementation process of S310 may refer to S302, which is not described herein in detail.

S311, the access network device receives the QoS parameter corresponding to the adjusted service frequency of the first service sent by the core network device, and allocates network resources for the first service according to the adjusted QoS parameter.

Specifically, the access network device receives QoS parameters corresponding to the adjusted service frequency of the first service sent by the core network device, and determines the resource allocation frequency of the first service again with reference to S304 and S305, and allocates network resources for the first service in the allocable network resources according to the resource allocation frequency; the specific allocation process may refer to S304 and S305, which are not described herein.
