Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a resource scheduling method in the internet of things, which is applied to a network side device, and includes:
and step 11, scheduling at least one carrier frequency resource as a special carrier frequency resource of a first type of terminal of a target area in a target time period.
In this step, under the condition that the first class of terminals have specific service requirements, dedicated carrier frequency resources are scheduled according to the requirements of the terminals. The specific meaning of the special carrier frequency resource is as follows: only the first type of terminals of the target area can use the resources within the target time period. In other words, the service of the first class terminal and other services are isolated by the special carrier frequency resource, so that the service quality is improved.
and the cell parameters of the target cell are used for indicating that other terminals except the first type terminal are forbidden to access the target cell in the target time period.
In this step, the cell parameter of the target cell is specially optimized for the dedicated carrier frequency resource, for example, the cell parameter of the target cell is a cell Barred field, and the cell Barred field is set to Barred (forbidden), that is, the terminal forbids access. As another example, the cell parameter of the target cell is cell Reserved ForOperator Use field and cell Reserved ForOperator Use field is set to reserved, i.e. the present cell has operator specific use.
It should be noted that, the system information may carry the cell parameters of the target cell only in the target time period, and the content included in the system information at other times is not described herein; alternatively, the system information may always carry the cell parameters of the target cell, but the cell parameters are only valid for the target time period; the present invention is not particularly limited herein.
Further, in the above embodiment of the present invention, step 11 includes:
acquiring service demand information of a first type of terminal in a target area;
and scheduling at least one carrier frequency resource as a special carrier frequency resource of the first type of terminal of the target area in the target time period according to the service demand information.
It should be noted that, the service requirement information may be obtained by the network side device from a service management device (may also be referred to as a service platform) of the first type of terminal, or may be obtained by the network side device after obtaining and summarizing the service requirement information from a plurality of first type of terminals.
The business requirement information may include: the time period for which dedicated carrier frequency resources need to be scheduled, the number of terminals of the first type for which dedicated resources need to be scheduled, the location area of the terminals of the first type for which dedicated resources need to be scheduled, etc., are not enumerated here.
In summary, according to the above embodiment of the present invention, dedicated carrier frequency resources are scheduled for the first class terminal of the target area in the target period according to the service requirement information, so as to implement resource isolation operation and ensure the service quality of the first class terminal of the target area in the target period.
It should be noted that, in order not to affect transmission of other services, the number of dedicated carrier frequency resources scheduled in the embodiment of the present invention needs to be smaller than the total amount of carrier frequency resources that can be scheduled in the target area, that is, the resource scheduling method provided in the embodiment of the present invention does not affect the existing network.
Further, in order to enable the first type terminal in the target area to access the target cell in the target time period, the method provided by the embodiment of the invention further includes:
sending network access signaling associated with the special carrier frequency resource to the first class terminal in the target area; or alternatively, the process may be performed,
and sending the network access signaling associated with the special carrier frequency resource to service management equipment (also called a service platform) of the first-class terminal, and forwarding the network access signaling associated with the special carrier frequency resource to the first-class terminal in a target area by the service management equipment.
Preferably, the network access signaling associated with the dedicated carrier frequency resource carries at least one of the following information:
frequency point information of the special carrier frequency resource;
the first type terminal accesses a target time period of the target cell; the method comprises the steps of,
and accessing the first type of terminal to the target cell.
The first type terminal randomly accesses the target cell according to the network access signaling.
In addition, in other time periods except the target time period, the available carrier frequency resources in the target area are scheduled as carrier frequency resources which can be used by all terminals in the target area; for example, taking NB-IoT cell a as an example, when there is no need to generate dedicated carrier frequency resources in the current time period, the NB-IoT cell a uses a multi-carrier technology to combine N carrier frequencies (n=1, 2,3, … …) and belongs to the same NB-IoT cell, where the service platform can dynamically change N according to network traffic.
In the target time period, other carrier frequency resources except the special carrier frequency resources in the target area are scheduled as carrier frequency resources which can be used by other terminals except the first-type terminal; for example, taking NB-IoT cell B as an example, NB-IoT cell B includes carrier frequency 1, carrier frequency 2, carrier frequency 3, where carrier frequency 1 and carrier frequency 2 are scheduled as dedicated carrier frequency resources for a target period of time, carrier frequency 3 may still be used by other terminals or other services for the target period of time.
In a time period without scheduling special resources, the network side equipment can uniformly schedule all available resources; and in the time period of scheduling the special resources, unified scheduling can be performed for the non-scheduled resource network side equipment, so that the utilization rate of the system resources can be effectively improved.
For example, a metro port covered NB-IoT cell C, which can dynamically schedule 2-3 carrier frequencies with single frequency points or with multi-carrier technology depending on network load, assuming that the NB-IoT cell C currently has three carrier frequencies available, e.g., no special requirements for the service platform. Assuming that 6-8 am and 17-19 pm have a large number of shared bicycle unlocking and locking operations around the subway, and meanwhile, meter reading and other various services of the street lamps are concurrent in the period, for example, the shared bicycle operation department needs to ensure the smoothness of the service, a part of resources (such as 2 carrier frequency resources) in the NB-IoT cell C can be independently separated in a target period (such as 6-8 am and 17-19 pm) according to the load of the shared bicycle operation department, so that a specific NB-IoT cell (i.e. a target cell) is formed, the cell parameters of the specific NB-IoT cell are specially optimized for the service, and a cellBarred field in a cell broadcast message is set to be barred, i.e. a terminal is forbidden to access. The cellReserve ForOPERATORUSE field is set to reserved, i.e., the cell has operator specific use. Meanwhile, the shared bicycle service platform also indicates that the terminal in the area randomly accesses the specific NB-IoT cell according to the requirement at a specific moment, so that service isolation is effectively formed, and in addition, the existing service can still be transmitted on the carrier frequency resource which is not scheduled in the original NB-IoT cell C.
For another example, the meter class centralized coverage area assumes that there are multiple internet of things terminals deployed in one NB-IoT cell D. For industry terminals, the planning is generally divided into two types, namely centralized reporting and downlink control. For the centralized reporting class, the reporting is generally randomized based on a fixed period of time, during which the resources thereof can effectively avoid collisions if reserved specifically for them. If the meter operation department needs to ensure the smoothness of the centralized reporting service, a part of resources (such as 2 carrier frequency resources) in the NB-IoT cell D can be independent within a specified period according to the load of the meter operation department to form a specific NB-IoT cell, the cell parameters of the specific NB-IoT cell are specially optimized for the service, and a cellBarred field in the cell broadcast message is set to be barred, namely, the terminal is forbidden to access. The cellReserve ForOPERATORUSE field is set to reserved, i.e., the cell has operator specific use. Meanwhile, the meter service platform also indicates that the terminal in the area randomly accesses the specific cell according to the requirement at the specific moment, so that service isolation is effectively formed, and in addition, the existing service can still be transmitted on the unscheduled carrier frequency of the original NB-IoT cell without interference.
In summary, the embodiment of the invention can dynamically establish the special carrier frequency resource for the service of the first type terminal in the target time period in advance according to the service requirement, so that the first type terminal in the target time period is scheduled to the target cell formed by the special carrier frequency resource, thereby realizing service isolation and improving the service quality of the first type terminal; meanwhile, in other time periods except the target time period, the network side equipment can schedule all carrier frequency resources at the same time, and the utilization rate of system resources can be further improved.
As shown in fig. 2, an embodiment of the present invention further provides a service transmission method, which is applied to a first type of terminal, including:
In this step, the cell parameter of the target cell is specially optimized for the dedicated carrier frequency resource, for example, the cell parameter of the target cell is a cell Barred field, and the cell Barred field is set to Barred (forbidden), that is, the terminal forbids access. As another example, the cell parameter of the target cell is cell Reserved ForOperator Use field and cell Reserved ForOperator Use field is set to reserved, i.e. the present cell has operator specific use.
It should be noted that, the system information may carry the cell parameters of the target cell only in the target time period, and the content included in the system information at other times is not described herein; alternatively, the system information may always carry the cell parameters of the target cell, but the cell parameters are only valid for the target time period; the present invention is not particularly limited herein.
And step 22, in the target time period, carrying out service transmission on the special carrier frequency resource scheduled by the network side equipment.
In this step, under the condition that the first class of terminals have specific service requirements, dedicated carrier frequency resources are scheduled according to the requirements of the terminals. The specific meaning of the special carrier frequency resource is as follows: only the first type of terminals of the target area can use the resources within the target time period. In other words, the service of the first class terminal and other services are isolated by the special carrier frequency resource, so that the service quality is improved.
Further, in order to enable the first type terminal in the target area to access the target cell in the target time period, the method provided by the embodiment of the invention further includes
Receiving network access signaling associated with the special carrier frequency resource sent by network side equipment or service management equipment of the first class terminal;
and accessing the target cell in the target time period according to the network access signaling.
Preferably, the network access signaling associated with the dedicated carrier frequency resource carries at least one of the following information:
frequency point information of the special carrier frequency resource;
the first type terminal accesses a target time period of the target cell; the method comprises the steps of,
and accessing the first type of terminal to the target cell.
The first type terminal randomly accesses the target cell according to the network access signaling.
It should be noted that, in order to ensure the transmission of the service of the first class terminal, the priority of the network access signaling is higher than the priority of other signaling, and the terminal accesses the target cell preferentially according to the network access signaling; or the terminal receives the network access signaling and then accesses the target cell at a certain moment according to the indication of the network access signaling.
For example, the terminal access service platform obtains a network access instruction, where the network access instruction instructs the terminal to access a specific NB-IoT cell of a specific frequency point at a specific time according to a service provider requirement, and the instruction has the highest priority, and after the terminal searches the NB-IoT cell, if a cellBarred field is set to barred and a cellreserved foroperator field is set to reserved in a broadcast message of the terminal, the terminal randomly accesses the cell according to a rule according to a platform requirement.
In summary, in the above embodiment of the present invention, the terminal accesses a specific NB-IoT cell composed of dedicated carrier frequency resources as required according to a network access instruction, so that service isolation is formed with services of other terminals, and reliability of service transmission is improved.

and in the target time period, other carrier frequency resources except the special carrier frequency resources in the target area are scheduled as carrier frequency resources which can be used by other terminals except the first-type terminal.
