Description

Downlink resource block reservation method and device

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for reserving downlink resource blocks.

Background

With the continuous evolution of networks, diversified industry application demands have exploded greatly. Network requirements for industry users have become an important deployment requirement for 5G. The hard slicing technology (reserved RB resources) which is the key base station configuration technology of the 5G greatly ensures the service quality and the safety of industrial users, and becomes a main mode for current campus deployment or specific area deployment. In addition, since the 5G device (5G base station) adopts a multi-element antenna device such as 192 elements, and the frequency band adopted by the 5G device is 3.5GHz, and the coverage range of the device is significantly less than that of the device in the frequency band of 2GHz or less, this will result in a multiple increase of the number of sites (number of base stations) in a unit area, and thus, the high cost of the base stations and the dense number of the sites will result in an exponential increase of the network construction cost. Therefore, operators are looking for a solution in which multiple operators co-establish a base station and use the co-established base station for network deployment. The co-building of the base station means that one base station can meet the requirements of multiple operators, and the equipment of the multiple operators is not centralized in the same base station for deployment.

After the base station is co-established and shared, the same equipment is generally required to meet the requirements of multiple operators, and the co-established shared base station does not have a prediction method for determining the reserved value of the RB while supporting the public network service (2C service) and the private network service (2B service) of multiple operators, which seriously affects the utilization rate of resources.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. 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. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

It should be noted that in the embodiments of the present application, "of", "corresponding" and "corresponding" may be sometimes used in combination, and it should be noted that the intended meaning is consistent when the difference is not emphasized.

For the convenience of clearly describing the technical solutions of the embodiments of the present application, in the embodiments of the present invention, the terms "first", "second", and the like are used to distinguish the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the terms "first", "second", and the like are not used to limit the quantity and the execution sequence.

At present, because the single cost of the 5G base station is high, and because the coverage area of the base station is small, the number of sites to be arranged in a unit area is large, and the cost of completing the deployment of the 5G communication network is high. Therefore, at present, a shared base station is co-established by a plurality of operators, so that the service requirements of the plurality of operators can be borne. However, for the co-established shared base station, how to reserve downlink RBs for services of different network types of different operators is an urgent problem to be solved.

In view of the above problems, embodiments of the present application provide a method for reserving downlink resource blocks, which can reasonably allocate downlink resource blocks and improve resource utilization. The method is applied to a system architecture as shown in fig. 1, and the system may include: a terminal 01, an access network device 02 and at least one core network device 03(03-1, 03-2, 03-3 and 03-4), where each core network device 03 corresponds to an operator core network (a private network core network (supporting 2B services) or a public network core network (supporting 2C services) or other network core networks of possible network types); for example, referring to fig. 1 (taking the example that only the private network corresponding to the 2B service and the public network corresponding to the 2C service exist, 03-1 may correspond to the core network of the public network of the operator a, 03-2 may correspond to the core network of the private network of the operator a, 03-3 may correspond to the core network of the public network of the operator B, and 03-4 may correspond to the core network of the private network of the operator B. After the access network device 02 and the access network device of the terminal 01 are connected, the access network device can access a public network core network or a private network core network of a corresponding operator through different core network devices 03. Of course, only one core network device 03 may actually exist, and the functions of the above-mentioned multiple core network devices may be completed.

It should be noted that, in the present application, one operator core network corresponds to one public network and a plurality of private networks.

Illustratively, referring to fig. 2, the functional modules in the core network device 03 may include a proposed region MR data acquisition module 031 and a service dependency analysis module 032.

The intended area MR data acquisition module 031 may acquire MR (Measurement Report) data of various private networks or public networks of various operators in an area where the access network device 02 (e.g., a base station) is to be deployed. For example, the MR data may include RRC connection number related data (maximum RRC connection number per target unit time (e.g., 1 hour)), average RRC connection number per target unit time, average number of RRC connections counted per target unit time, maximum number of RRC connections counted per target unit time, and the like of traffic corresponding to a network of each network type (e.g., a public network or any private network) within a preset time period.

For example, taking the proposed region as an example where two operators exist, the acquisition content of the proposed region MR data acquisition module 031 can be as shown in table 1 below.

TABLE 1

The service dependency analysis module 032 may determine, through a certain calculation, whether the service in the actual scene corresponding to the network data mainly depends on the RRC connection number by using the MR data acquired by the corresponding intended region MR data acquisition module 031 through cooperation with the service dependency analysis module 032 in the other core network device corresponding to the intended deployment access network device 02. Of course, if all the core networks correspond to the same core network device, the service dependency analysis module included therein independently completes the above calculation process.

Illustratively, referring to fig. 2, the access network device 02 includes a network parameter acquisition module 021, a service guarantee parameter acquisition module 022, a real-time RB calculation module 023, and an RB resource reservation and allocation module 024.

The network parameter collection 021 may collect information such as frequency point information, public and private network identifiers, DNN information (actually, a slice identifier may also be used, and DNN information is mostly used as an example in this application) of all services (services to be accessed) that need to access to the access network device to be deployed, so as to identify an operator and a network of each service, and specifically, collected data may refer to data shown in table 2 below.

TABLE 2

Service identification	Frequency point information	Public and private network identification	DNN
				1	A	PU	-
2	B	PU	-
				3	A	Pr	1
4	A	Pr	1
				5	B	Pr	1
n	B	Pr	j

Wherein, a represents that the service belongs to a carrier of an operator a, B represents that the service belongs to a carrier of an operator B, PU represents that the network type of the service is a public network, Pr represents that the network type of the service is a private network, DNN is 1 represents a private network 1, DNN is i represents a private network i, and DNN is j represents a private network j. In this embodiment of the present application, the access network device may extract frequency point information from an MIB (management information base) broadcast signaling, obtain a public/private network identifier from an SIB (system information block) signaling, and extract DNN information of a target service from a PDU Session Establishment Request signaling. If the network slice identifier is needed, the access network device needs to extract from a PDU (protocol data unit) session Qos flow.

The service guarantee parameter acquiring module 022 may extract parameters related to service characteristics of the service to be accessed, for example, 5QI (quality of service) for determining Qos level parameters, RSRP (reference signal receiving power), CQI (channel quality indication, channel quality indicator, Bler (block error rate), PL (path loss), and the like, and these information are provided to the real-time RB calculating module 023 for calculating the downlink RB requirement value of each service to be accessed, and the specifically acquired data may be referred to the data shown in table 3 below.

TABLE 3

Service identification	RSRP	5QI	CQI	Bler	PL
						1	RSRP1	Q1	CQI1	Bler1	PL1
2	RSRP2	Q2	CQI2	Bler2	PL2
						3	RSRP3	Q3	CQI3	Bler3	PL3
n	RSRPn	Qn	CQIn	Blern	PLn

Taking a 5G communication system as an example, the priority level needs to collect 5QI (5G QoS Identifier) (used to identify QoS (Quality of Service) of 5G), index the 5G QoS characteristics according to the value of 5QI, refer to table 4 for specific contents of mapping standard 5QI to 5G QoS characteristics, and refer to table 5 for meaning of 5G QoS characteristics.

TABLE 4

TABLE 5

For convenience of understanding, the Qos level parameters in the embodiment of the present application may all adopt the default priority shown in table 3, which is not described herein again. In this embodiment, the access network device extracts 5QI information (including Qos level parameters), RSRP, Bler, CQI, PL, and the like of a service flow of a target service from an SMF (session management function) -UDM (unified data management function) Registration signaling.

The RB resource reservation and allocation module 024 is configured to determine a reservation and allocation condition of a downlink RB of each service to be accessed according to the downlink RB requirement value calculated by the real-time RB calculation module 023 and a network type determined by the network parameter acquired by the network parameter acquisition module 021.

For example, taking a 5G communication network as an example, referring to fig. 3, a practical device in the access network device 02 may include a radio frequency unit and a baseband processing unit. The radio frequency unit is connected to the baseband processing unit through a common public radio interface (cpri (ecrpi)), and the public network core network (5GC1) of the operator a, the public network core network (5GC2) of the operator B, the private network core network (5GC3) of the operator a, and the private network core network (5GC4) of the operator B are connected to the baseband processing unit of the access network device 2 through NG interfaces.

The 5G baseband processing unit includes a Control Plane (CP) and a User Plane (UP). The control plane has an identification module (specifically, the identification module can be judged by a PLMN (public land mobile network), an APN (access point name), a DNN (Data network name), and the like) for the private network core network and the public network core network of different operators, so that the public network core network and the private network core network of different operators can be distinguished. The network parameter collection module 021, the service guarantee parameter collection module 022, the real-time RB calculation module 023, and the RB resource reservation and allocation module 024 may also all be disposed in the CP.

The 5G radio frequency unit comprises an antenna unit, a switch and a transceiver. The transceiver includes a Digital Up Conversion (DUC), a digital to analog converter (DAC), a transmission antenna (TX), a reception antenna (RX), an analog to digital converter (ADC), and a Digital Down Conversion (DDC).

Specifically, in the technical solution provided by the present invention, the access network device 02 configures one path of carrier for each operator, where each path of carrier is used to carry services of all network types of the operator corresponding to the carrier, and the network type is at least one of a public network and a plurality of private networks. In the following description of the present application, a service whose network type is a public network is referred to as a public network service, and a service whose network type is a private network is referred to as a private network service. Each carrier includes an uplink carrier and a downlink carrier, where the communication link corresponding to the uplink carrier is composed of the antenna unit, the switch, the RX (RX1 and RX2), the ADC (ADC1 and ADC2), the DDC (DDC1 and DDC2), and the 5G baseband processing unit in fig. 3, and the communication link corresponding to the downlink carrier is composed of the antenna unit, the switch, the TX (TX1 and TX2), the DAC (DAC1 and DAC2), the DUC (DUC1 and DUC2), and the 5G baseband processing unit in fig. 3.

For example, as shown in fig. 3, when 2 operators (operator a and operator B, respectively) are accessed into the access network device, the operator a performs data transmission through the first carrier when initiating a public network service or a private network service, and the user terminal of the operator B performs data transmission through the second carrier when initiating a private network service. Wherein the first carrier comprises a first transceiver (DUC1, DAC1, TX1, DDC1, ADC1, RX1), a first combiner, a switch, and an antenna unit; the second carrier includes a second transceiver (DUC2, DAC2, TX2, DDC2, ADC2, RX2), a second combiner, a switch, and an antenna unit.

Based on the contents shown in fig. 1 to fig. 3, an embodiment of the present application provides a method for reserving downlink resource blocks, which is applied to the access network device 02. Referring to fig. 4, the method includes 401-:

401. and determining the network type of each service to be accessed corresponding to the target carrier in the current unit time.

The target carrier is any one of the multiple paths of carriers configured by the access network. The proposed access service is directed to the access network device to send a request for the service to be started.

Optionally, because the access network device is configured with multiple carriers, before step 401, in order to ensure that step 401 is smoothly implemented, it is necessary to first determine which services to be accessed belong to one carrier, so with reference to fig. 4, as shown in fig. 5, step 401 further includes 400A and 400B:

400A, obtaining the frequency point information of all the services to be accessed of the access network equipment.

For example, the frequency point information may be obtained by the network parameter acquisition module, and the specific frequency point information example may refer to table 1, which is not described herein again.

And 400B, determining the quasi-access service with the same frequency point information as the quasi-access service belonging to the same carrier.

Note that the frequency point information is actually a number given to a fixed frequency. The frequency intervals are all 200 khz. This divides the radio frequency bands from 890mhz, 890.2mhz, 890.4mhz, 890.6mhz, 890.8mhz, 891mhz.

Optionally, as shown in fig. 6, because the technical solution provided in the embodiment of the present application is based on a hard slicing technique, and a premise of implementing the hard slicing technique is that too many resources required by a service to be accessed corresponding to an access network device require that the hard slicing technique be used to reasonably allocate resources, and if the resources required by the service to be accessed corresponding to the access network device itself are not too many, the resources are allocated completely according to the requirements, and the performance of the co-established shared base station is not affected at all, and the technical solution provided in the present application does not need to be executed, so before the step 401, the core network device 03 further needs to execute the following steps:

s1, acquiring the average RRC connection number and/or the average RRC connection number with data transmission of each target unit time of each access service to be accessed corresponding to the current unit time in the preset time period.

Illustratively, the target unit time may be 1 hour; in order to save computing resources and ensure that the collected data can reflect the traffic usage of each network carried by the access network device, the preset time period may be two consecutive weeks of tuesdays (any working day) and sundays (any holiday). The busy hour can be determined by the traffic using condition of the corresponding user of the operator, for example, the traffic using condition can be 9:00-11:00 and 14:00-17:00 in working days, and the traffic using condition can be 10:00-17:00 in non-working days. The network here includes a public network and a private network.

Illustratively, the step S1 is mainly performed by the intended region MR data acquisition module 031 in the core network device 03 shown in fig. 2.

S2, determining the unit time of the large connection number according to the average RRC connection number of busy hour and/or the average RRC connection number with data transmission of all the services to be accessed in the preset time period.

When the sum of the average RRC connection number of all services to be accessed in a first target hour of busy hours in a preset time period accounts for that the access network equipment can bear the maximum RRC connection number in one hour and is larger than a preset ratio (for example, 30%), determining that the first target hour is the target unit time with the large connection number. Or, when the ratio of the sum of the average data transmission RRC connection numbers in the second target hour of busy hours of all services to be accessed in the preset time period to the maximum data transmission RRC connection number that the access network device can carry in one hour is greater than a preset ratio (for example, 30%), determining that the second target hour is the target unit time with a large connection number.

And S3, judging whether the ratio of the number of the target unit time with the large connection number to the total target unit time number corresponding to busy hour in the preset time period is larger than a second preset percentage.

Executing S4 when the ratio of the number of the large-connection-number standard unit time to the total target unit time corresponding to all busy hours is larger than a second preset percentage; when the ratio of the number of the large connection number standard unit times to the total target unit times corresponding to all busy hours is not more than the second preset percentage, S1 is executed.

Illustratively, the second predetermined percentage may be 30%, or any other feasible value, and is not limited herein.

S4, sending a corresponding instruction to the access network device to make it execute the foregoing downlink resource block reservation method.

Because the traffic used by each network in the time of the large connection number unit time is more, it can be considered as very traffic dependent, and if the ratio of the large connection number target unit time to the total target unit time in busy hours exceeds a certain ratio, it indicates that each network carried by the access network device is more RRC connection number dependent, that is, the corresponding intended access service needs more resources, and a corresponding instruction needs to be sent to the access network device to make the access network device execute the technical scheme provided by the embodiment of the present application.

For example, the steps S2-S4 are performed by the service dependency analysis module 032 in the core network device 03 shown in fig. 2.

It should be noted that, in practice, the core network device may not perform the step S3, and after the step S2, it is determined whether to execute the step S1 or send a corresponding instruction to the core network device so as to execute the step 401, directly according to an occupation ratio of the number of the large connection number standard unit times to the total target unit time number corresponding to the busy hour in the preset time period. In addition, the ratio of the number of the large-connection-number unit-of-unit time to the total target unit time number corresponding to all busy hours is equal to a second preset percentage, which can be attributed to a case that the ratio of the number of the large-connection-number unit-of-unit time to the total target unit time number corresponding to all busy hours is greater than the second preset percentage, or can be attributed to a case that the ratio of the number of the large-connection-number unit-of-unit time to the total target unit time number corresponding to all busy hours is less than the second preset percentage, and the example corresponding to fig. 6 is exemplified by a case that the ratio of the number of the large-connection-number unit-of-unit time to the total target unit time number corresponding to all busy hours is less than the second preset percentage, but the present application does not specifically limit this.

Optionally, with reference to fig. 7 in combination with fig. 5, step 401 may specifically include 4011 and 4012:

4011. and acquiring the public and private network identification and the network identification of the service to be accessed.

The network identifier is a data network name DNN or a network slice identifier.

Specifically, the public and private network identifier and the network identifier are obtained by the network parameter acquisition module. Reference may be made specifically to the contents of table 2 above.

4012. And determining the network type of the service to be accessed according to the public and private network identification and the network identification of the service to be accessed.

Specifically, how to determine the network type of each service to be accessed according to the public-private network identifier and the network identifier may refer to the content expressed in table 2 above, and details are not repeated here.

402. And acquiring a downlink RB required value of the proposed access service in the current unit time.

Optionally, with reference to fig. 8 in combination with fig. 5, the step 402 may specifically include 4021-4023:

4021. and acquiring service guarantee parameters of the service to be accessed.

The service guarantee parameters at least comprise control channel element CCE polymerization degree parameters; the polymerization degree parameter includes at least any one or more of: RSRP, Bler, CQI, PL. The service guarantee parameters may be obtained by the service guarantee parameter acquisition module, and may be as shown in table 3.

4022. And determining the CCE polymerization degree corresponding to the service to be accessed according to the polymerization degree parameter of the service to be accessed.

Specifically, a Physical Downlink Control Channel (PDCCH) is mainly used for transmitting downlink control information and UL Grant, so that a terminal correctly receives a Physical Downlink Shared Channel (PDSCH) and allocates uplink resources for the Physical Uplink Shared Channel (PUSCH), where an allocation unit is CCE (where 1 CCE equals to 6 Resource Element Groups (REGs) and 72 Resource Elements (REs)). For one PDCCH, it is composed of one or more CCEs, and the number of CCEs allocated differs according to aggregation levels.

In practice, there is a certain functional relationship between the CCE (control Channel Element) aggregation level and the above mentioned RSRP, Bler, CQI and PL, but for convenience, the calculation of the CCE aggregation level is described as follows by taking the aggregation level parameter including only RSRP as an example:

in the embodiment of the present application, CCE aggregation levels corresponding to different RSRPs need to be determined according to a pre-stored correspondence between RSRPs and CCE aggregation levels and number of space division layers. For example, the correspondence relationship may be shown in the following table 6:

TABLE 6

CCE aggregation level	Number of air separation layers	RSRP interval
			2	2	[-85dBm，+∞)
4	1	[-95dBm，-85dBm)

For example, taking an example of determining an aggregation coefficient of a service to be accessed, where one network class of the operator a is a private network, a specific implementation process is as follows:

1. and obtaining the Qos level parameter of each public network service and the Qos level parameter of each private network service under the operator A.

The total accumulated number of the target services is the total number of the target services smaller than or equal to the current Qos level parameter (for example, when the current Qos level parameter is 20, if there are 3 public network services and 2 private network services for which the Qos level parameter is less than or equal to 20, the total accumulated number is 5, and the total service number is the total number of all the public network services and all the private network services under the operator a (for example, when there are 20 private network services under the operator a, and 30 public network services, the total service number is 50).

3. And determining a second CDF curve according to the Qos grade parameter of each private network service under the operator A.

Illustratively, the second CDF curve is shown in fig. 11, and the abscissa represents the Qos level parameter and the ordinate represents the ratio of the total number of the private network services to the total number of the services. The total accumulated number of the private network services is the total number of the private network services smaller than or equal to the current Qos level parameter (for example, when the current Qos level parameter is 20, 2 private network services with Qos level parameters smaller than or equal to 20 are inquired at this time, the total accumulated number is 2, and the total service number is the total number of all the private network services under the operator a (for example, when the total number of the private network services under the operator a is 20, the total service number is 20).

4. And determining a third CDF curve according to the Qos level parameter of each private network service in the private network core network i under the operator A.

The total accumulated number of the private network services is the total number of the private network services smaller than or equal to the current Qos level parameter (for example, when the current Qos level parameter is 20, 2 private network services with the Qos level parameter smaller than or equal to 20 in the private network core network i are inquired at this time, the total accumulated number is 2, and the total service number is the total number of all the private network services under the operator A (for example, when the total number of the private network services in the private network core network i under the operator A is 20, the total service number is 20).

wherein Add_AiThe aggregation coefficient of each private network service (i.e., the intended access service of which the network category is a private network) in the ith private network of the cloud operator a is represented, Qos1 represents a first Qos level parameter, Qos2 represents a second Qos level parameter, Qos3 represents a third Qos level parameter, and Qos4 represents a fourth Qos level parameter.

Illustratively, the first predetermined ratio is the same as the second predetermined ratio, such as 90%. The third predetermined ratio is the same as the fourth predetermined ratio, e.g., 95%.

And the aggregation coefficient of each service to be accessed in any private network of other operators can be known in the same way.

Specifically, the operation and maintenance personnel can set a first preset ratio, a second preset ratio, a third preset ratio and a fourth preset ratio according to actual requirements, and the details are not repeated here.

40232. And calculating the pending downlink RB required value of the planned access service in the current unit time according to the CCE polymerization degree corresponding to the planned access service and a preset rule.

For example, the pending downlink RB requirement value may be calculated according to the following formula:

wherein RB^DLThe pending downlink RB requirement value, N, representing the proposed access service_RBAll RB values which can be supported by a carrier corresponding to the quasi-access service are represented, CCE represents CCE polymerization degree corresponding to the quasi-access service, S represents the number of space division layers corresponding to the quasi-access service, and P represents the number of space division layers corresponding to the quasi-access service_DLAnd the occupation ratio of the downlink RB in the frame structure of the carrier wave corresponding to the service to be accessed is shown.

40233. And under the condition that the network type of the service to be accessed is a public network, determining the pending downlink RB required value of the service to be accessed in the current unit time as the downlink RB required value of the service to be accessed in the current unit time.

40234. And under the condition that the network type of the service to be accessed is a private network, calculating a downlink RB required value of the service to be accessed in the current unit time according to the aggregation coefficient of the service to be accessed and the pending downlink RB required value of the service to be accessed.

For example, taking the target carrier as the carrier of the operator a, the downlink RB requirement value of the jth service to be accessed in the ith private network can be obtained according to the following formula:

wherein the content of the first and second substances,

represents the downlink RB requirement value, RB, of the jth service to be accessed in the ith private network of the operator A_AijRepresents the pending downlink RB requirement value of the jth service to be accessed in the ith private network of the operator A,

and the aggregation coefficient of the jth service to be accessed in the ith private network of the operator A.

Specifically, for convenience of use in practice, the downlink RB requirement values of each service to be accessed of two operators, specifically each operator, can be referred to as the following table 7:

TABLE 7

In order to facilitate the subsequent 4032 and 4034 steps, the intended access services with network categories of public network and private network need to be respectively arranged, and the downlink RB requirement values in table 7 are arranged from large to small or from small to large according to the Qos class parameter.

403. And under the condition that the sum of the downlink RB required values of all the services to be accessed in the current unit time is greater than the rated downlink RB value of the target carrier, reserving the downlink RB for the services to be accessed in the current unit time according to the network type of the services to be accessed and the downlink RB required values.

Optionally, when the Service guarantee parameter further includes a Qos (Quality of Service) level parameter, with reference to fig. 8 and as shown in fig. 13, step 403 may specifically include 4031 and 4032:

4031. under the condition that the sum of the downlink RB required values of all the services to be accessed in the current unit time is greater than the rated downlink RB value of the target carrier, determining a first downlink RB guarantee value according to the downlink RB required values of all the services to be accessed in the first service set in the current unit time; the first service set is composed of all the proposed access services of which the network type is public network and which are corresponding to the target carrier in the current unit time.

Specifically, taking the target carrier as the carrier of the operator a as an example, the nominal downlink RB value thereof can be obtained according to the following formula:

wherein the content of the first and second substances,

nominal downlink RB value, RB, for a target carrier_AFor the maximum RB value that the target carrier can carry,

is the occupation ratio of the downlink RB in the frame structure of the target carrier.

Taking the target carrier as the carrier of operator a as an example, the first downlink RB guarantee value may be obtained by the following formula:

wherein the content of the first and second substances,

for the first downlink RB guarantee value,

represents the maximum value of the downlink RB requirement values of the proposed access service of the public network of all network types in the target carrier,

represents the average of the downlink RB requirement values for all public network services in the target carrier.

4032. And sharing and allocating downlink RBs corresponding to the first downlink RB guarantee value to all the services to be accessed in the first service set according to the Qos grade parameters of all the services to be accessed in the first service set.

Specifically, when the target carrier corresponds to the operator a, the RB resource corresponding to the first downlink RB guarantee value is shared by downlink data of the virtual access service to the public network in the current unit time for each network class corresponding to the target carrier in the current unit time (for example, when the first downlink RB guarantee value is determined to be 50MB, the RB resource of 50MB is shared and allocated by downlink data of the virtual access service to the public network in the current unit time for each network class corresponding to the target carrier in the current unit time, and the greater the Qos level parameter, the better the RB resource is used).

Therefore, because the intended access service of which the network type is the public network is limited by the public network, the priority in all services is not high, if the downlink RB value of the target carrier is not enough, all the public networks can share the RB resource corresponding to the first downlink RB guarantee value, namely, the service use of the public network user is guaranteed, the public network is also guaranteed not to occupy too many RB resources, and the resource utilization rate is improved.

Optionally, with reference to fig. 14 in combination with fig. 13, step 403 may further include 4033 and 4034:

4033. calculating a second downlink RB guarantee value corresponding to the second service set according to the rated downlink RB and the first downlink RB guarantee value; the second service set is composed of all the network types corresponding to the target carrier in the current unit time as the intended access services of the private network.

Specifically, taking the operator a corresponding to the target carrier as an example, the second downlink RB guarantee value may be obtained by referring to the following formula:

wherein, the first and the second end of the pipe are connected with each other,

indicating a second downlink RB guarantee value.

4034. And according to the Qos grade parameters of all the services to be accessed in the second service set, according to a preset sequence, sequentially according to the downlink RB requirement values of the services to be accessed in the second service set in the current unit time, and reserving downlink RBs corresponding to the guarantee values of the second downlink RBs for the services to be accessed in the second service set.

For example, the preset order may be an order of the Qos level parameters from large to small. Specifically 4034, the RB resources corresponding to the second downlink RB guarantee value may be allocated according to the Qos class parameter of the service to be accessed of the private network for each network class corresponding to the target carrier in the current unit time, and according to the descending RB requirement value of each private network service in sequence from the largest to the smallest.

Further optionally, with reference to fig. 15 in combination with fig. 14, the 4034 step may specifically include 40341 and 40342:

40341. and according to the Qos grade parameters of all the services to be accessed in the second service set and the downlink RB requirement values of the services to be accessed in the second service set in the current unit time, reserving the downlink RBs corresponding to the second downlink RB guarantee value for the services to be accessed in the second service set according to a preset sequence until the distributed downlink RBs in the downlink RBs corresponding to the second downlink RB guarantee value account for the preset percentage of the total amount of the downlink RBs corresponding to the second downlink RB guarantee value.

Illustratively, the preset order may be an order of the Qos level parameters from large to small. The preset percentage may be 70%, which is only an example and may be determined according to practical circumstances.

40342. And according to the Qos level parameters of all the services to be allocated and accessed of the downlink RB which is not independently allocated and reserved in the second service set, sharing and allocating the downlink RB which is not allocated and reserved in the downlink RB corresponding to the guarantee value of the second downlink RB to all the services to be allocated and accessed in the second service set.

Thus, based on the above

technical solutions

40341 and 40342, since the network type is the priority of the dedicated access service itself, if the downlink RB value of the target carrier is not enough, the downlink RB resource (corresponding to the downlink RB requirement value) required by the dedicated access service in the second service set may be allocated to the dedicated access service in the current unit time according to the descending order of the Qos level parameter until the RB resource corresponding to the second downlink RB guarantee value occupies a preset percentage (e.g., 70%) of the total amount, because the RB resource of the target carrier is not enough at this time, if the reserved RB is continuously allocated to the dedicated access service in the second service set as needed, a part of the dedicated access service in the second service set will not have available downlink resource RB subsequently, and at this time, the remaining RB resources in the downlink RB resource corresponding to the second downlink RB guarantee value are shared and allocated to the dedicated access service set without reservation in the second service set And the RB resources to be allocated to the quasi-access services ensure the subsequent use of the quasi-access services to be allocated. Meanwhile, because different Qos level parameters of the intended access service are different, the shared downlink RB resources also need to be shared according to the Qos level parameters of each intended access service to be allocated, that is, the larger the Qos level parameters are, the better the shared RB resources can be used, thereby not only ensuring the reservation requirement of the intended access service in which the network category corresponding to the target carrier at the current unit time is a private network, but also ensuring that downlink RB resources are available for the intended access service in which each network category is a private network, and improving the resource utilization rate as a whole.

Optionally, referring to fig. 16 in conjunction with fig. 4, the method further includes 404:

404. and under the condition that the sum of the downlink RB required values of all the services to be accessed in the current unit time is less than or equal to the rated downlink RB value, reserving the downlink RB corresponding to the downlink RB required value of the services to be accessed in the current unit time for the services to be accessed.

Therefore, the downlink RB can be reserved for each service to be accessed in the current unit time as required under the condition of ensuring sufficient downlink RB resources, and the use requirement of the service is ensured.

Based on the technical solution provided by the embodiment of the present application, in order to solve the problem that one access network device (shared base station) configures different carriers for different operators, the present application first determines the network type of each service to be accessed of a certain path of carrier. And then after the downlink RB required value of each quasi-access service in the current unit time is obtained, when the sum of the downlink RB required values of all the quasi-access services in the current unit time is larger than the rated downlink RB, namely the downlink RB required to be provided by the carrier exceeds the rated downlink RB which can be provided by the carrier, the downlink RB is reserved for the quasi-access service in the current unit time according to the network type and the downlink RB required value of the quasi-access service. According to the technical scheme provided by the embodiment of the application, because a plurality of factors are integrated and considered to reserve the downlink RB for the quasi-access service corresponding to a certain carrier wave of the access network equipment, the method and the device are more in line with actual requirements, and therefore the resource utilization rate of the access network equipment can be improved.
