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, apparatus, and system.

Background

With the continuous development of narrowband band internet of things (NB-IoT), NB-IoT has been widely used in more industries. Current NB-IoT may support quality of service (QoS) control functions for user traffic. However, in the implementation process, the QoS control policy of the Long Term Evolution (LTE) is generally directly multiplexed.

The NB-IoT and LTE have different corresponding service types, different QoS requirements of different service types and different corresponding QoS parameter ranges. For example, LTE may be generally applied to services such as video transmission and voice call, and the delay range in the corresponding QoS parameter may be 10ms to 30ms, while NB-IoT may be generally applied to services such as smart street lamps, shared bicycles, and smart water meters and smart electricity meters, and the delay range in the corresponding QoS may be 100ms to 10 months. Therefore, the control QoS strategy of LTE has no guiding significance to the practical application of NB-IoT, and cannot really achieve the purpose of guaranteeing the QoS of NB-IoT service.

Disclosure of Invention

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

The technical scheme is as follows:

in a first aspect, the present application provides a communication method, which may be applied to a core network device, and the method may include: acquiring a quality of service (QoS) parameter of a first service supported by core network equipment; the QoS parameter includes a 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 into the QoS parameter, so that the access network equipment can obtain the resource allocation frequency corresponding to the service frequency of the service, and the resource allocation frequency is used for allocating network resources for the service; thereby guaranteeing the QoS of the service.

With reference to the first aspect, in a 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 parameter according to the actual requirement, so that the diversity of the QoS parameter 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 within a preset time; the service index comprises time delay and/or packet loss rate; n is greater than 1; comparing the N service indexes with parameters of 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 the M service indexes meeting the QoS parameters. In the possible implementation manner, the QoS parameter and the index of the service can be kept synchronous, so that the QoS of the service is further guaranteed.

With reference to the first aspect or any one of the foregoing possible implementation manners, in another possible implementation manner, the adjusting the service frequency of the first service according to M service indicators meeting the QoS parameter 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 appropriately reduced 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 adjusting the service frequency of the first service according to M service indicators meeting the QoS parameter 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 appropriately increased 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 a QoS parameter corresponding to the adjusted service frequency of the first service; and sending the QoS parameter corresponding to the adjusted service frequency of the first service to the access network equipment to instruct the access network equipment to allocate network resources for the first service according to the QoS parameter 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 ensure the QoS of the service.

In a second aspect, the present application provides another communication method, which may be applied to an access network device, and which may include: receiving a QoS parameter of a first service sent by core network equipment; the first service is any service supported by both the core network equipment and the access network equipment; the QoS parameter includes a 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 a possible implementation manner, determining a resource allocation frequency of a first service according to a service 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; the resource allocation frequency of the first service is equal to or less than the service frequency of the first service. In this possible implementation manner, the queue to which the service belongs may 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, which improves the flexibility of determining the resource allocation frequency of the first service. In general, the service resource allocation frequency is equal to the service frequency, and of course, the service resource allocation frequency may be smaller than the service frequency.

With reference to the second aspect, in a possible implementation manner, the QoS parameter further includes traffic volume, and allocating network resources for the first service among the allocable network resources may include: acquiring the traffic of a first service; and in the allocable network resources, the network resources allocated for the first service in the allocable network resources according to the traffic. In this possible implementation manner, when the traffic volume of the first service is a fixed value, the network resource satisfying the traffic volume may be allocated to the first service, which may avoid wasting the network resource and improve the utilization rate of the network resource.

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

Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance. The technical features described in the first and second descriptions have no sequence or magnitude order.

In the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs.

In the description of the present application, a "/" indicates a relationship in which the objects associated before and after are an "or", for example, a/B may indicate a or B; in the present application, "and/or" is only an association relationship describing an associated object, and means that there may be three relationships, for example, a and/or B, and may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. Also, in the description of the present application, "a plurality" means two or more than two unless otherwise specified. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. 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 multiple.

In the embodiments 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, which is not limited in the present application.

For the sake of understanding, the technical terms related to the present application are explained first.

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

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

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

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

Traffic volume may refer to the size of data transmitted when the traffic communicates with other devices. The traffic of one service may include uplink traffic and/or downlink traffic. For example, the upstream traffic volume of a service may be 1 Kilobytes (KB).

The service QoS guarantee scheme of LTE and NB-IoT in the prior art is briefly explained.

Wherein an LTE or NB-IoT network may include one or more terminal devices, access network devices, LTE or NB-IoT core network devices, and so on; one or more services are run on a terminal device; the access network equipment 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 comprises the following steps: when a service 1 (for example, a video service) needs to be run on a terminal device 1, an LTE core network device establishes a link of the service 1 on an access network and the terminal, searches a QoS parameter (information such as a Quality Class Identifier (QCI), a priority, a time delay, and a packet loss rate) value of the service 1 in a QoS service printing table of LTE, and then sends the QoS parameter of the service 1 to the access network device.

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

Then the access network device schedules the services in different queues according to Proportional Fair (PF) scheduling algorithm or Round-Robin (RR) algorithm, and when scheduling to a queue, allocates network resources to the services in each queue according to the order of the priority of the services in the queue from high to low. After the network resources are allocated to the service 1, the service 1 transmits data with the access network device through the network resources, so as to ensure the QoS of the service 1.

The service QoS guarantee scheme for NB-IoT is as follows: when a service 2 (for example, an intelligent water meter service) needs to be run on a terminal device 2, an NB-IoT core network device establishes a link of the service 1 on an access network and the terminal, and searches a QoS parameter of the service 2 in a QoS service printing table of a multiplexed LTE, and since a range of information such as delay, packet loss rate, and the like in the QoS service printing table of the multiplexed LTE cannot be matched with a range of information such as delay, packet loss rate, and the like of the intelligent water meter service, only a 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 device.

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

Then the access network device schedules the services in different queues according to Proportional Fair (PF) scheduling algorithm or Round-Robin (RR) algorithm, and allocates network resources for the hit services as much as possible. After the network resources are allocated to the service 2, the service 2 transmits data with the access network device through the network resources, so as to ensure the QoS of the service 2.

According to the above NB-IoT QoS guarantee scheme, it can be seen that, since NB-IoT and LTE have large service type differences, QoS requirements of different services are different, and types of corresponding QoS parameters and ranges of the QoS parameters are different. Therefore, the QoS guarantee scheme of the QoS service printing table directly multiplexing LTE cannot guarantee the service QoS of NB-IoT.

For example, in the QoS guarantee scheme of NB-IoT, if service 2 has higher priority than service 3, but service 3 (e.g., a shared bicycle service) has a higher requirement on the delay, in this case, the access network device preferentially allocates network resources to service 2 and then allocates network resources to service 3, which may result in that the delay requirement in the QoS of service 3 cannot be met.

In the NB-IoT network, since the traffic types included in the NB-IoT network are rich, QoS requirements are different between different traffic types, for example, frequencies of data transmission (traffic frequencies) are different between different traffic; the service frequency of the intelligent traffic light service may be 1 time per second, and the service frequency of the intelligent water meter service may be 1 time per month. Based on this, the embodiment of the present application provides a communication method, where a service frequency of a service is added to a QoS parameter, so that an access network device can obtain a resource allocation frequency corresponding to the service frequency of the service, and allocate a network resource for the service by using 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, a network architecture in the embodiment of the present application is first described. The communication method in the embodiment of the present application can be applied to the following network architecture.

It should be noted that the network architecture and the scenario are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided by the embodiment of the present application, and as a person having ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided by the embodiment of the present application is also applicable to similar architectures and scenarios.

receiving a QoS parameter of a first service sent by core network equipment; the first service is any service supported by both the core network equipment and the access network equipment; the QoS parameter includes a 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.

On the other hand, the embodiment of the present application provides a communication method, which can be applied to the communication device 20 shown in fig. 2.

It should be noted that the communication method provided in 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 guarantee QoS of the services. The method in this embodiment may be adopted when allocating network resources to each service, the process is 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 is not described in detail.

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

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

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

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

The time for configuring the QoS parameters of the multiple services by the core network device is not limited uniquely in the embodiments of the present application. For example, the configuration occasion may be at a design stage of the communication apparatus, or at a use stage of the communication apparatus and before executing the communication method of the embodiment of the present application.

For example, when an International Mobile Equipment Identity (IMEI) of the terminal device is imported, service requirement confirmation may be performed, one or more service properties running under the mobile device may be analyzed, and a service QoS parameter corresponding to the property may be established for each service.

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

The service frequency may include an uplink service frequency and/or a downlink service frequency. 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.

For example, the QoS parameters of the configured services may be as shown in table 1.

TABLE 1

It should be noted that table 1 only shows an exemplary form of recording QoS parameters of multiple services, and should not be construed as a specific limitation to the recording form.

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

The traffic may include uplink traffic and/or downlink traffic. Specifically, the uplink traffic volume may be the same as the downlink traffic volume, or the uplink traffic volume may be different from the downlink traffic volume.

For example, the QoS parameters of the configured services may be as shown in table 2.

TABLE 2

Wherein 0 indicates that the traffic demand is uncertain; and T is a single-transmission data volume theoretical value.

It should be noted that table 2 only shows an exemplary form of recording QoS parameters of multiple services, and should not be construed as a specific limitation to the recording form.

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 the plurality of services.

When the core network device acquires the first service, the first service may be determined in a manner of a service identifier, a service name, or a 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 also include one or more of the following: the service volume of the first service, the time delay of the first service and the 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 and the core network device instruct the access network device to allocate network resources for a service according to a QoS parameter of a received service by transmitting the QoS parameter of the service. S302 may be implemented as: the core network equipment sends the QoS parameter of the first service to the access network equipment, and the access network equipment is indicated by the QoS parameter to allocate network resources for the first service according to the QoS parameter of the first service.

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 and the core network device instruct the access network device to allocate network resources for the service according to the received QoS parameter of the service by transmitting allocation instruction information and the QoS parameter of the service. S302 may be implemented as: the core network equipment sends the QoS parameters of the first service and the allocation indication information to the access network equipment so as to indicate the access network equipment 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 parameter of the first service sent by the core network equipment.

In S303, the QoS parameter of the first service received by the access network device, 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.

In particular, implementations of S304 may include, but are not limited to, implementation 1 or implementation 2 described below.

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

Illustratively, 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 obtains the configuration information, and searches for a resource allocation frequency corresponding to a 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 comprises an uplink service frequency and a downlink service frequency, the resource allocation frequency of the first service is a resource allocation frequency corresponding to the uplink service frequency and the downlink service frequency.

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

And 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 pre-configured in the access network device, each queue corresponds to a different service frequency range, and one queue includes one or more services whose service frequencies belong to its service frequency range; each queue corresponds to a different frequency of resource allocation.

Exemplary access network device configuration information for the plurality of queues may be as shown in table 3.

TABLE 3

It should be noted that table 3 only shows an exemplary form of recording information of a plurality of queues, and should not be construed as a specific limitation to the recording form.

Specifically, implementation 2 may include, but is not limited to, scheme a through scheme C described below.

In the scheme a, the service frequency of 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 for a queue whose corresponding uplink service frequency range includes the uplink service frequency of the first service in the information of the plurality of queues, uses the queue as a queue to which the first service belongs, and uses the resource allocation frequency corresponding to the queue as the resource allocation frequency of the first service.

In the scheme B, the service frequency of 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 for a queue whose corresponding downlink service frequency range includes the downlink service frequency of the first service from the information of the plurality of queues, uses the queue as a queue to which the first service belongs, and uses the resource allocation frequency corresponding to the queue as the resource allocation frequency of the first service.

In the scheme C, the service frequency of 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 for a queue whose corresponding uplink service frequency range includes the uplink service frequency of the first service and a queue whose corresponding downlink service frequency range includes the downlink service frequency of the first service from the information of the plurality of queues, uses the two queues as queues to which the first service belongs, and uses the resource allocation frequencies corresponding to the two queues as resource allocation frequencies 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 may be a dynamic adjustment value; or otherwise.

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

Optionally, 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 are sequentially allocated to the multiple services.

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, implementations 1 to 4 described below.

And when the QoS parameter of the first service does not comprise the traffic, the access network equipment allocates the network resource for the first service according to the best available mode in the allocable network resources by using 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, by using the resource allocation frequency, uplink network resources for the first service in an already-available manner among the allocable uplink network resources.

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 a downlink network resource for the first service in the resource allocation frequency according to the best available manner in the allocable downlink network resources.

In 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 frequency according to the resource, and allocates the uplink network resource and the downlink network resource to the first service according to the best possible manner among the allocable uplink network resource and allocable downlink network resource.

It should be noted that, when the traffic volume sent or received by the first service is not a fixed value, or 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 adopted 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 of implementation 2 to implementation 4 may be adopted to allocate network resources to the first service.

The method comprises the steps that access network equipment judges the relation between the service volume of a first service and allocable network resources; if the traffic 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 of the first service is greater than the allocable network resource and the traffic of other services existing at the resource allocation frequency of the first service is less than the allocable network resource, the network resource can be allocated to the first service by adopting the method of implementing 3; if the traffic volume of the first service is greater than the allocable network resource and the traffic volume of other services which do not exist under the resource allocation frequency of the first service is less than the allocable network resource, the method of implementing 4 may be adopted to allocate the network resource for the first service.

When the relationship between the traffic of the first service and the allocable network resources is judged, 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 larger than the current allocable uplink network resources and/or allocable downlink network resources.

And 2, the access network equipment allocates the 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 volume of the first service, the access network device allocates, by using the resource allocation frequency, an uplink network resource that can satisfy the uplink traffic volume of the first service to the first service among the allocable uplink network resources.

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

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

And 3, the access network equipment allocates frequency according to the resource, and allocates network resources meeting the traffic volume for the service of which the other traffic volume under the resource allocation frequency of the first service is less than the traffic volume of the allocable network resource in the allocable network resources.

Specifically, the access network device allocates the network resource with reference to the method of implementation 2, when the other traffic volume of the first service under the resource allocation frequency is smaller than the service of the allocable network resource, and then allocates the network resource to the first service when the first traffic volume is smaller than the allocable network resource.

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 all allocable network resources for the first traffic.

Further, the communication method provided by the embodiment of the present application may further monitor QoS of the first service on 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, a user may configure a time for monitoring and adjusting QoS of a service according to an actual requirement, which is not specifically limited in the embodiment of the present application.

For example, the QoS of the 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 service index of the first service 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 device calls service indexes of each service recorded in a network side log of the core network, and searches N time delays and/or N packet loss rates of the first service in a preset time through the log to serve as N indexes of the first service.

S307, the core network equipment compares the N service indexes with parameters of 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: and the core network equipment compares the N time delays and/or the N packet loss rates in the N service indexes with the time delay and/or the packet loss rate of the corresponding service index in the QoS parameter respectively, and if the time delay and/or the packet loss rate of the service index are less than or equal to the time delay and/or the packet loss rate in the QoS parameter, the service index is considered as the service index meeting the QoS parameter of the first service.

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

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

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

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

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

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

Wherein the first threshold is greater than the second threshold.

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

The M service indicators satisfying the QoS parameter may be M service indicators continuously satisfying the QoS parameter, or M service indicators discontinuously satisfying the QoS parameter.

It should be noted that the granularity of the service frequency of the increased or decreased first service may be configured according to actual situations, and 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 dynamically adjusted value or otherwise.

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

In S309, the core network device obtains the 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 the QoS parameter 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 parameter corresponding to the adjusted service frequency of the first service.

Specifically, the implementation process of S310 may refer to S302, and is not described herein again.

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

Specifically, the access network device receives a QoS parameter sent by the core network device and corresponding to the adjusted service frequency of the first service, and refers to S304 and S305, re-determines the resource allocation frequency of the first service, and allocates a network resource to the first service in allocable network resources by using the resource allocation frequency; for a specific allocation process, reference may be made to S304 and S305 described above, which is not described herein again.
