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 industrial application requirements 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) uses 192-element multi-element antenna devices, and the frequency band used by the 5G device is 3.5GHz, and the coverage range is significantly smaller than that of the device in the frequency band of 2GHz or less, this will result in the multiplied increase of the number of stations (number of base stations) in a unit area, and thus, the high base station cost and the dense number of stations will result in the exponential increase of the network construction cost. Therefore, operators are seeking a solution for co-establishing a base station by multiple operators and performing network deployment by using the co-established base station. 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 has no 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 invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, 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 derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "such as" in an embodiment of the present invention 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 invention, "of", "corresponding" and "corresponding" may be sometimes used in combination, and it should be noted that, when the difference is not emphasized, the intended meaning is consistent.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used for distinguishing the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like are not limited in number or execution order.

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, an embodiment of the present application provides a method for reserving downlink resource blocks, which can reasonably allocate downlink resource blocks and improve resource utilization. The method is applied to the 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 of the terminal 01 is connected with the access network device, the terminal can access the core network of the public network or the core network of the private network of the 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 MR data acquisition module 031 in the planned area may acquire MR (Measurement Report) data of various private networks or public networks of various operators in the area where the access network device 02 (e.g., a base station) is planned 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 and DNN (Data network name) information (actually, a slice identification code may also be used, and DNN information is mostly taken as an example in this application) of all services (to-be-deployed access network services) that need to be accessed, so as to identify an operator and a network of each service, and specifically, the collected Data may be as shown in table 2 below.

TABLE 2

Wherein, a represents that the service belongs to a public network carrier of an operator a, B represents that the service belongs to a public network carrier of an operator B, C represents that the service belongs to a private network carrier of the operator a, D represents that the service belongs to a private network carrier of the operator B, DNN is 1 representing a private network 1, DNN is i representing a private network i, and DNN is j representing 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, 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 provisioning parameter acquiring module 022 may extract parameters related to service characteristics of the service to be accessed, such as 5QI (quality of service parameter), RSRP (reference signal receiving power), CQI (channel quality indication, Bler (block error rate), PL (path loss), and the like, which 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 refer to 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 the 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 the network class determined by the network parameter acquired by the network parameter acquisition module 021.

Illustratively, 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 described above may also all be arranged 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, taking the network category including a public network and multiple private networks as an example, in the technical scheme provided by the present application, the access network device 02 configures two carriers for each of multiple operators, where the two carriers include a public network carrier and a private network carrier, where the public network carrier provides support for services corresponding to the public network of one operator, and the private network carrier provides support for services corresponding to all the private networks of one operator. Each path of carrier includes an uplink carrier and a downlink carrier, a communication link corresponding to the uplink carrier is composed of the antenna unit, the switch, the RX, the ADC, the DDC, and the 5G baseband processing unit in fig. 3, and a communication link corresponding to the downlink carrier is composed of the antenna unit, the switch, the TX, the DAC, the DUC, and the 5G baseband processing unit in fig. 3. When initiating private network service or public network service, the user terminals corresponding to the operator 1 and the operator 2 transmit related data through the communication link corresponding to the uplink carrier and the communication link corresponding to the downlink carrier.

For example, as shown in fig. 3, when 2 operators (operator a and operator B, respectively) are accessed in the access network device 02, a user terminal of the operator a may transmit via a first carrier when initiating a service related to a private network; when the user terminal of the operator A initiates the related service of the private network, the related service can be transmitted through the second carrier; when the user terminal of the operator B initiates the related service of the public network, the related service can be transmitted through the third carrier wave; when initiating the related service of the private network, the user terminal of the operator B may transmit through the fourth carrier. 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 comprises a second transceiver (DUC2, DAC2, TX2, DDC2, ADC2, RX2), a second combiner, a switch and an antenna unit; the third carrier comprises a third transceiver (DUC3, DAC3, TX3, DDC3, ADC3, RX3), a first combiner, a switch and an antenna unit; the fourth carrier includes a fourth transceiver (DUC4, DAC4, TX4, DDC4, ADC4, RX4), a second combiner, a switch, and an antenna unit.

In this embodiment, the access network device 02 may be an access network device (BTS) in a global system for mobile communication (GSM), a Code Division Multiple Access (CDMA), an access network device (Node B, NB) in a Wideband Code Division Multiple Access (WCDMA), an access network device (eNB) in a Long Term Evolution (Long Term Evolution, LTE), an access network device (eNB) in an internet of things (IoT) or a narrowband internet of things (NB-IoT), an eNB in a future 5G mobile communication network or a future evolved Public Land Mobile Network (PLMN), which is not limited in this embodiment.

For example, the terminal in the embodiment of the present application may be named differently 01, such as a User Equipment (UE), an access terminal, a terminal unit, a terminal station, a mobile station, a remote terminal, a mobile device, a wireless communication device, a vehicle user equipment, a terminal agent, or a terminal device. The terminal may be a mobile phone, a tablet computer, a desktop, a laptop, a handheld computer, a notebook, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a Personal Digital Assistant (PDA), an Augmented Reality (AR) Virtual Reality (VR) device, and other devices that can communicate with a base station.

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

401. and acquiring the service guarantee parameters of each service to be accessed in the target service set.

The target service set consists of all the services to be accessed of the same carrier wave which belong to the access network equipment configuration; the service guarantee parameters at least comprise a control channel element CCE polymerization degree parameter and a Qos grade parameter; the CCE aggregation level parameters include at least any one or more of: reference signal received power RSRP, block error rate Bler, channel indication CQI, path loss PL. 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 2, 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. Thus, 125 radio frequency bands are divided from 890mhz, 890.2mhz, 890.4mhz, 890.6mhz, 890.8mhz, 891mhz … … 915mhz at a frequency interval of 200khz, and each band is numbered from 1, 2, 3, 4 … … 125.

Optionally, in order to determine which network of which operator finally carries the service that is reserved by the downlink RB, referring to fig. 6 in conjunction with fig. 5, the method further includes:

and 400C, acquiring the network identification of the service to be accessed.

Wherein the network identifier is a DNN or a network slice identity. Specifically, the network identifier is obtained by the network parameter acquisition module.

And 400D, determining the operator type and the network type of the service to be accessed according to the frequency point information and the network identification of the service to be accessed.

Specifically, how to determine the operator category and the network category of each service to be accessed according to the frequency point information and the network identifier may refer to the description contents below table 2, which is not repeated herein.

Optionally, as shown in fig. 7, 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 to reasonably allocate resources using the hard slicing technique, and if the resources required by the service to be accessed corresponding to the access network device itself are not too many, the performance of the co-established shared base station is not completely affected by allocating the resources completely according to the requirements, and the technical solution provided in the present application does not need to be executed, so the core network device 03 needs to execute the following steps before step 401:

s1, acquiring the average RRC connection number and/or the average number of RRC connections with data transmission of each target unit time when each service to be accessed corresponding to the current unit time belongs to busy hour in a preset time period by the access network equipment.

The network here includes a public network and a private network.

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

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.

And S2, determining the unit time of the large connection number according to the average RRC connection number of busy hours and/or the average number of transmitted RRC connections 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 number of data-transferred RRC connections in the second target hour of busy hours of all the services to be accessed in the preset time period to the maximum number of data-transferred RRC connections 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 large-connection-number target unit time.

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 greater than the second preset percentage, S1 is performed.

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

And S4, sending a corresponding instruction to the access network equipment to enable the access network equipment to execute the 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. 7 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.

402. And determining the RB required value of the downlink resource block of the planned access service in the current unit time according to the service guarantee parameters of the planned access service.

Optionally, with reference to fig. 8 in combination with fig. 4, the step 402 may specifically include 4021 and 4022:

4021. and determining the CCE polymerization degree corresponding to the service to be accessed according to the CCE 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 following description is made on the calculation of the CCE aggregation level by taking the aggregation level parameter as an example only including RSRP:

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 an RSRP and a CCE aggregation level and a 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)
			8	1	[-105dBm，-95dBm)
16	1	(-105dBm，-∞)

4022. And determining the downlink RB required value of the planned access service in the current unit time according to the CCE polymerization degree of the planned access service.

Since the Qos level parameter itself may affect the condition of reserving the downlink RB for the service to be accessed, the downlink RB requirement of the service to be accessed is also related to the Qos level parameter, and the private network service is more affected, so in view of this point, as shown in fig. 9 in conjunction with fig. 8, 4022 may specifically include 40221 + 40224:

40221. under the condition that the network type of the service to be accessed is a private network, determining the aggregation coefficient of the service to be accessed according to the Qos level parameters of all the services to be accessed in the target service set; and the aggregation coefficient is used for indicating the downlink resource block allocation limit of the service to be accessed in the carrier wave corresponding to the target service set.

For example, taking the determination of the aggregation coefficient of the private network service of the operator a as an example, a specific implementation process is as follows:

1. and obtaining the Qos level parameters of each public network service and the Qos level parameters of each private network service of all operators.

Specifically, the Qos level parameter of each public network service and the Qos level parameter of each private network service may be determined by querying in table 3. Illustratively, the Qos level parameter may be a default priority in table 3.

2. And determining a first CDF curve according to Qos grade parameters of all private network services of the operator A.

Illustratively, the first CDF curve is shown in fig. 10, 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 in all the private network services of the operator a 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 of the operator a (for example, when the total number of the private network services of the operator a is 20, the total service number is 20).

3. And determining a second CDF curve according to the Qos level parameters of all private network services in the private network core network i 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 accumulated total number of private network services to the total number of 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 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).

4. Determining a first Qos level parameter according to the first CDF curve and a first preset ratio; and determining a second Qos level parameter according to the second CDF curve and a second preset ratio.

5. And determining the aggregation coefficient of each private network service in the private network core network i of the operator A according to the first Qos level parameter and the second Qos level parameter. Wherein the polymerization coefficient satisfies a coefficient formula:

wherein the content of the first and second substances,

represents an aggregation coefficient of each private network traffic in the private network core network i of the operator a, Qos1 represents a first Qos level parameter, and Qos2 represents a second Qos level parameter.

The network category of other operators is the same as the aggregation coefficient of the service to be accessed of the private network.

Illustratively, the first predetermined ratio is the same as the second predetermined ratio, e.g., 95%.

Specifically, the operation and maintenance personnel can set the first preset ratio and the second preset ratio according to actual requirements, which is not described herein again.

40222. 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 by referring 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.

40223. And under the condition that the network type of the service to be accessed is the 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.

40224. And under the condition that the network type of the service to be accessed is a private network, calculating the downlink RB requirement 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 requirement value of the service to be accessed.

For example, taking the private network carrier of operator a as an example, 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 first and the second end of the pipe are connected with each other,

indicating 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 steps 403 and 4031-4034, the intended access services with network categories of public network and private network need to be arranged according to the Qos class parameter from large to small or from small to large, and the downlink RB requirement values in table 7 are arranged.

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

Optionally, with reference to fig. 12 in combination with fig. 4, the step 403 may specifically be:

403. and reserving the downlink RB corresponding to the rated downlink RB value for the intended access service according to the Qos grade parameters of all the intended access services in the target service set and the downlink RB required values of the intended access services in the current unit time according to the preset sequence.

Therefore, the required downlink RB resources can be timely allocated to the to-be-accessed service with higher priority according to the Qos level parameters, and the user experience is ensured.

Optionally, in order to ensure that all services to be accessed have downlink RB resources available, referring to fig. 13 in combination with fig. 4, step 403 may specifically include 4031 and 4034:

4031. and determining a downlink RB sharing value according to the downlink RB required values of all the services to be accessed in the target service set in the current unit time.

For example, taking the carrier corresponding to the target service set as a public network carrier, the nominal downlink RB value of the carrier may be obtained according to the following formula:

wherein the content of the first and second substances,

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

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

At this time, the downlink RB share value can be obtained by the following formula:

wherein the content of the first and second substances,

a value is shared for the downlink RB of the public network carrier,

represents the maximum value of the downlink RB requirement values of all services to be accessed in the public network carrier,

and the average value of the downlink RB requirement values of all services to be accessed in the public network carrier is shown.

Similarly, the nominal downlink RB value when the carrier corresponding to the target service set is a private network carrier can be obtained by the following formula:

wherein the content of the first and second substances,

nominal downlink RB value, RB, for private network carrier_BFor the maximum RB value that the private network carrier can carry,

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

Similarly, when the carrier corresponding to the target service set is a private network carrier, the downlink RB sharing value can be obtained by the following formula:

the value is shared for the downlink RBs of the private network carrier,

represents the maximum value of the downlink RB requirement values of all services to be accessed in the private network carrier,

and the average value of the downlink RB requirement values of all services to be accessed in the private network carrier is shown.

4032. And calculating a downlink RB guarantee value according to the rated downlink RB value and the downlink RB sharing value.

And the downlink RB guarantee value is the difference of the rated downlink RB value minus the downlink RB sharing value.

4033. And reserving the downlink RB corresponding to the downlink RB guarantee value for the planned access service according to the Qos level parameters of all the planned access services in the target service set and the downlink RB requirement values of the planned access services in current unit time in sequence according to a preset sequence until all the downlink RBs corresponding to the downlink RB guarantee value are reserved.

The preset order may be an order of the Qos level parameters from large to small.

4034. And sharing and allocating the downlink RB corresponding to the downlink RB sharing value to the to-be-allocated quasi-access service according to the Qos level parameter of the to-be-allocated quasi-access service of the downlink RB corresponding to the downlink RB guarantee value which is not reserved in all the to-be-accessed services in the target service set.

Specifically, in the sharing and allocating process, the downlink RB corresponding to the downlink RB sharing value may be preferentially used with a large Qos level parameter.

Therefore, based on the technical scheme corresponding to 4031-4034, the requirement of the quasi-access service with the high Qos level parameter can be ensured, and the normal use of the quasi-access service with the low Qos level parameter can be ensured, so that the use requirements of all users can be met, downlink RB resources are reasonably allocated, and the resource utilization rate is improved.

Optionally, with reference to fig. 14 in conjunction with fig. 4, the method further includes 404:

404. and reserving the downlink RB corresponding to the rated downlink RB value for the pseudo-access service according to the downlink RB required value of the pseudo-access service in the current unit time under the condition that the sum of the downlink RB required values of all the pseudo-access services in the target service set in the current unit time is less than or equal to the rated downlink RB value.

According to the technical scheme provided by the embodiment of the application, because the downlink RB reservation is carried out on the pseudo-access service corresponding to a certain carrier wave of the access network equipment by integrating multiple factors, the actual requirement is better met, and the resource utilization rate of the access network equipment can be improved.
