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) 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 "e.g.," 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 PLMN (public land mobile network) information and DNN (Data network name) information (actually, a slice identification code may also be used, and DNN information is mostly used as an example in this application) of all services (to-be-accessed services) that need to access to the to-be-deployed access network device, so as to identify an operator and a network of each service, and specifically, collected Data may refer to the Data shown in table 2 below.

TABLE 2

Wherein, PLMN a represents that the service to be accessed belongs to operator a, PLMN B represents that the service to be accessed belongs to operator B, DNN is 1 and represents private network 1, DNN is i and represents private network i, and DNN is j and represents 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 priority parameter calculation module 023, and the user access and resource 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 scheme provided by the present invention, the access network device 02 only carries the services of all network types of all operators through one path of target 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. The channel 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 the user terminals corresponding to the operator a and the operator B initiate the private network service or the public network service, the user terminals transmit the relevant data through the communication link corresponding to the uplink carrier and the communication link corresponding to the downlink carrier.

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 (evolved node B, 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 (IoT-NB-B, NB-NB), an access network device 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 01 in the embodiment of the present application may be named differently, 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 determining the network type of each service to be accessed corresponding to the current unit time of the access network equipment.

Optionally, as shown in fig. 5, 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 command to the core network device to execute the step 401 according to an occupation ratio of the number of the large-connection-number unit times to the total target unit time number corresponding to busy hours 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. 5 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. 6 in combination with fig. 4, the step 401 may specifically include steps 4011 and 4012:

4011. acquiring a network identifier of a service to be accessed; the network identification is a data network name DNN or a network slice identity.

Specifically, the network identifier is obtained by the network parameter acquisition module. The contents of table 2 can be referred to specifically.

4012. And determining the network type of the service to be accessed according to the network identifier of the service to be accessed.

Specifically, how to determine the network type of each service to be accessed according to the network identifier may refer to the description below table 2, which is not described herein again.

Optionally, in order to conveniently distinguish between services to be accessed of different operators, referring to fig. 7 in conjunction with fig. 6, the method further includes X1 and X2:

and X1, acquiring Public Land Mobile Network (PLMN) information of the service to be accessed.

Specifically, the PLMN information is obtained by the network parameter acquisition module. The contents of table 2 can be referred to specifically.

And X2, determining the operator category of the service to be accessed according to the PLMN information of the service to be accessed.

Specifically, how to determine the operator category of each service to be accessed according to the PLMN information may refer to the content expressed below table 2, which is not described herein again.

402. And acquiring service guarantee carrier parameters of the service to be accessed.

The service guarantee parameters at least comprise a control channel element CCE polymerization degree parameter and a Qos level 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.

403. And determining the RB required value of the downlink resource block of the service to be accessed in the current unit time according to the service guarantee parameters of the service to be accessed.

Optionally, with reference to fig. 8 in combination with fig. 4, step 403 specifically includes 4031 and 4032:

4031. 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.

The accumulated total number of the public network services is the total number of the public network services smaller than or equal to the current Qos level parameter (for example, when the current Qos level parameter is 20, at this time, the accumulated total number is 3 if there are 3 public network services of which the Qos level parameter is smaller than or equal to 20 in all the public network services of all the operators are inquired, and the total service number is the total number of all the public network services of all the operators (for example, when the public network services of all the operators are 30 in total, the total service number is 30).

4. And determining a third CDF curve according to the Qos level parameters of each private network service of all operators.

Illustratively, the third CDF curve is shown in fig. 12, and the abscissa represents the Qos level parameter and the ordinate represents the ratio of the cumulative total 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, the accumulated total number is 2 if 2 private network services with Qos level parameters smaller than or equal to 20 in all the private network services of all the operators are inquired at this time, and the total service number is the total number of all the private network services of all the operators (for example, when the total number of the private network services of all the operators is 20, the total service number is 20).

Wherein the polymerization coefficient satisfies a coefficient formula:

wherein,

represents the aggregation coefficient for each public network service of operator a,

represents an aggregation coefficient of each private network service in a private network core network i of an operator a, 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.

The same can be known about the aggregation coefficient of each service to be accessed in any public network or private network of other operators.

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.

40322. 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_DLIndicating the downlink R in the frame structure of the carrier wave corresponding to the service to be accessedAnd B is the ratio of B.

40323. And calculating the downlink RB required value of the to-be-accessed service in the current unit time according to the aggregation coefficient of the to-be-accessed service and the pending downlink RB required value of the to-be-accessed service.

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

wherein,

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.

Similarly, the downlink RB requirement value of the ith service to be accessed in the public network of the operator a can be obtained according to the following formula:

wherein,

indicating the downlink RB requirement value, RB, for the ith service to be accessed in the public network of operator A_AiRepresents the pending downlink RB requirement value of the ith service to be accessed in the public network of the operator a,

and the aggregation coefficient of the ith service to be accessed in the public 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 404, 4041-4044, 40441 and 40442, the proposed access services whose network categories are public and private networks 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 level parameter.

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 greater than the rated downlink RB value of the target carrier, reserving the downlink RB for the services to be accessed according to the downlink RB required values, the network category and the Qos level parameters of the services to be accessed in the current unit time.

Optionally, with reference to fig. 14 in combination with fig. 4, the step 404 may specifically include 4041-:

4041. 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 proposed access services of which all network types corresponding to the access network equipment in the current unit time are public networks.

Specifically, the nominal downlink RB value can be obtained according to the following formula:

wherein,

for a nominal downlink RB value, RB_maxFor access to network equipmentMaximum RB value, P, that a configured carrier can carry_DLAnd the occupation ratio of the downlink RB in the frame structure of the carrier configured for the access network equipment.

The first next safeguard value may be given by the following formula:

wherein,

is the first downstream safeguard value for the first time,

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

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

4042. 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 the intended access services of which all network types corresponding to the access network equipment in the current unit time are private networks.

Specifically, the second downlink RB guarantee value may be obtained by referring to the following formula:

wherein,

indicating a second downlink RB guarantee value.

4043. And according to the Qos grade parameters of all the services to be accessed in the first service set, sharing and allocating the downlink RB corresponding to the first downlink RB guarantee value to all the services to be accessed in the first service set.

Specifically, the RB resource corresponding to the first downlink RB guarantee value is shared by downlink data of each network type public network access-planned service corresponding to the current unit time 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 the downlink data of each network type public network access-planned service corresponding to the current unit time in the current unit time, and the greater the Qos level parameter is, the better the RB resource is used).

4044. And according to the Qos grade parameters of all the services to be accessed in the second service set, and according to the downlink RB requirement values of the services to be accessed in the second service set in the current unit time in sequence according to the preset sequence, reserving the downlink RB corresponding to the second downlink RB guarantee value 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, 4044 may be configured to allocate RB resources corresponding to the second downlink RB guarantee value according to the Qos class parameter of the service to be accessed to the private network of each network class corresponding to the target carrier in the current unit time, and according to the descending RB requirement values of each private network service in sequence from large to small.

Further optionally, in order to ensure that each service to be accessed has downlink RB resources available, referring to fig. 15 in combination with fig. 14, the step 4044 may specifically include steps 40441 and 40442:

40441. and reserving the downlink RB corresponding to the second downlink RB guarantee value for the virtual access service in the second service set according to the Qos level parameters of all the virtual access services in the second service set and the downlink RB requirement values of the virtual access services in the second service set in sequence according to the preset sequence until the downlink RB which is distributed and reserved in the downlink RB corresponding to the second downlink RB guarantee value accounts for the preset percentage of the total amount of the downlink RB corresponding to the second downlink RB guarantee value.

For example, 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 the actual situation.

40442. And 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 planned to be accessed in the second service set according to the Qos level parameters of all the services to be allocated and planned to be accessed, which are not allocated and reserved in the downlink RB independently in the second service set.

Thus, based on the above

technical solutions

40441 and 40442, because the network type is the priority of the dedicated network quasi access service itself, if the downlink RB value is not enough, the downlink RB resource (corresponding to the downlink RB requirement value) needed by the dedicated network quasi access service in the second service set may be allocated to the dedicated network quasi access service in the current unit time according to the descending order of the Qos level parameter until the reserved part of 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 network quasi access service in the second service set as needed, a part of the reserved RB subsequently does not have the downlink resource available to the dedicated network access service in the second service set, and at this time, the remaining RB resource in the downlink RB resource corresponding to the second downlink RB guarantee value is shared and allocated to the reserved downlink RB resource in the second service set And the intended access services to be allocated ensure the subsequent use of the intended access services to be allocated. Meanwhile, because the Qos level parameters of different services to be accessed are different, the shared downlink RB resources also need to be shared according to the Qos level parameters of each service to be accessed, i.e., the larger the Qos level parameter is, the better the shared RB resources can be used, thereby not only ensuring the reservation requirement of the service to be accessed, in which the network class corresponding to the target carrier in the current unit time is a private network, but also ensuring that the service to be accessed, in which each network class is a private network, has downlink RB resources available, and improving the resource utilization rate as a whole.

Optionally, with reference to fig. 16 in conjunction with fig. 4, the method further includes 405:

405. 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, under the condition of ensuring that the downlink RB resources are sufficient, the downlink RB is reserved for each planned access service in the current unit time according to the requirement, and the use requirement of the planned access service is ensured.

Based on the technical solution provided by the embodiment of the present application, in order to address a situation that the access network device carries all services of all operators through one path of carrier, the present application first determines a network type of each service to be accessed, which corresponds to the access network device in a current unit time. And then after determining the downlink RB requirement value of each service to be accessed in the current unit time according to the service guarantee parameter of each service to be accessed, when the sum of the downlink RB requirement values of all the services to be accessed in the current unit time is greater than the rated downlink RB of the target carrier, namely when the downlink RB required to be provided by the carrier configured by the access network equipment exceeds the rated downlink RB which can be provided by the carrier, reserving the downlink RB for the services to be accessed according to the downlink RB requirement value of the services to be accessed in the current unit time, the network category and the Qos level parameter. According to the technical scheme provided by the embodiment of the application, because a plurality of factors (Qos level parameters, downlink RB required values and network categories) are integrated and considered to reserve the downlink RB for the access network equipment in the corresponding planned access service in the current unit time, the method and the device are more suitable for actual requirements, and therefore the resource utilization rate of the access network equipment can be improved.
