Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a resource allocation method applied to a decision device, including:
wherein, in a case where the wireless resource is being occupied, the at least one first device includes: a device requesting use of a radio resource and a device occupying the radio resource; in case the radio resource is unoccupied, the at least one first device comprises: a device requesting use of radio resources.
Optionally, the radio resource includes a time domain resource, a frequency domain resource, a time-frequency domain resource, and the like. And the determined second equipment is any one or more of the at least one first equipment.
In the embodiment of the invention, the first device performs the attribution judgment of the wireless resources according to the reference information of the first device, namely, the first device judges which first devices can use the wireless resources currently. It should be noted that, before step 11, the method further includes: a first request sent by a first device is received, and the first request is used for requesting to use wireless resources. If the wireless resource is occupied, the device occupying the wireless resource and the device sending the first request (one device may send the first request, or multiple devices may send the first request) need to be considered; however, if the wireless resource is not occupied currently, only the device that sent the first request (which may be one device sending the first request, or multiple devices sending the first request) needs to be considered.
It should be noted that at least one first device may be a device of the same system, or may be a device of a different system; the embodiment of the invention is suitable for GSM (Global System for Mobile Communications ), NB-IoT (Narrow Band Internet of Things), LTE (Long Term Evolution), 5G mMTC (massive Internet of Things communication), uRRLC (Low delay and high reliability communication), eMBB (enhanced Mobile Bandwidth) and future Mobile communication systems.
For wireless communication systems of different systems sharing wireless resources, the wireless communication systems can be deployed on the same device or different devices.
As an optional embodiment, the reference information of the first device comprises at least one of:
priority of resource usage by the first device:
a frequency resource utilization of the first device.
Wherein the first device and the decision device are deployed as a common device; alternatively, the first device and the decision device are deployed on different devices.
In the process of determining the attribution of the radio resource, the first device needs to acquire reference information (the reference information may also be referred to as network status information) from each first device in order to determine the usage right of the radio resource. When the first equipment and the decision equipment are deployed together, finishing the interaction of the reference information through a signal message in the equipment; and when the first equipment and the decision equipment are at different equipment, the interaction of the reference information is completed by transmitting the first message and the second message. For example, as shown in fig. 2, the specific interaction method is as follows:
1) the decision-making equipment sends a first message to the first equipment;
the protocol format of the transmission message includes, but is not limited to, SNMP between the network manager and the base station, X2AP between the base stations, S1AP between the core network and the base station, and the like, and is not limited herein. The first message includes reference information requesting the first device to report the first device.
2) The first equipment sends a second message to the decision-making equipment;
the protocol format of the transmission message includes but is not limited to SNMP between the network manager and the base station, X2AP between the base stations, S1AP between the core network and the base station, etc. The second message contains the reference information of the first device requested in the first message.
As still another alternative embodiment, in the case that the reference information of the first device includes a priority of the first device to use the resource, step 12 includes:
and selecting at least one first device as a second device which can currently use the wireless resources according to the priority from high to low.
When a certain device needs to use the radio resource due to the service, the radio resource that is being used by the device with the higher priority cannot be preempted, and the radio resource that is being used by the device with the lower priority can be preempted. When resource preemption is executed, selecting the wireless resource used by the equipment with the lowest priority; when the traffic of a certain system is reduced and the wireless resource is not needed to be used, the wireless resource is directly released.
Wherein the priority of the first device to use the resource is determined by at least one of the following information:
a network type of the first device;
a system bandwidth of the first device;
available spectrum resources of a first device;
a network capacity of the first device;
a traffic load of the first device;
a traffic type of the first device.
Optionally, the priority of the resource used by each first device is configured in advance according to the service type of the main service served by the first device, and the system with the higher priority has the priority of the wireless resource.
Example 1: the three systems of GSM, NB-IoT and LTE are deployed together at 935MHz-949 MHz. The GSM mainly bears voice service, so that the priority is highest; the NB-IoT mainly carries smoke alarm monitoring service with the second priority; LTE bears internet service and has the lowest priority. Namely, the priority of using wireless resources by each system is configured to be GSM > NB-IoT > LTE.
When the GSM needs to occupy the wireless resources, the wireless resources used by the LTE are occupied preferentially, and the wireless resources used by the NB-IoT are occupied secondly;
when NB-IoT needs to occupy wireless resources, the wireless resources used by GSM cannot be occupied, and only the wireless resources used by LTE can be occupied;
LTE can not occupy the wireless resources of other systems;
when the GSM and NB-IoT networks are idle, the shared spectrum is released for LTE use.
Optionally, the size of the system bandwidth of the first device is inversely proportional to the priority level. I.e. the first device with a small system bandwidth has priority for the use of radio resources. Wherein the system bandwidth of the first device comprises any one of:
the minimum scheduling unit in the first device is smaller and higher in priority, for example, the priority of wireless resources used by each system is configured to be NB-IoT 3.75K > LTE 180K > GSM 200K;
the minimum allocable system bandwidth in the first device is smaller, and the lower the system bandwidth is, the higher the priority is, for example, the priority of each system using the radio resource is configured to LTE 1.4M < GSM 200K — NB-IoT 200K;
and the ratio of the minimum allocable system bandwidth to the minimum scheduling unit in the first device is smaller, and the priority of the corresponding first device is higher.
Optionally, the size of the available spectrum resource of the first device is inversely proportional to the priority level, that is, the first device with less available spectrum resource has a priority for using the wireless resource. Wherein the available spectrum resources of the first device include any one of:
for example, the priority of the wireless resources used by each system is configured to be LTE 5M < GSM 800K < NB-IoT 200K, where the wireless resources are sharable resources of each system in the 900M frequency band;
the ratio of the frequency bandwidth allocated by the first device to the minimum scheduling unit in the wireless resource is smaller, and the priority of the corresponding first device is higher;
the sum of the frequency bandwidths allocated by the first equipment in the total resources is smaller, and the priority is higher;
and the ratio of the sum of the allocated frequency bandwidths of the first equipment in the total resources to the minimum scheduling unit is smaller, and the priority of the corresponding first equipment is higher.
The total resource includes a radio resource and a dedicated resource of each of a plurality of first devices capable of using the radio resource, and the dedicated resource may be a sum of a frequency band resource in which the radio resource is located and other frequency band resources, such as 1800M, 1900M, 2100M, 2600M, 3500M, and the like.
Optionally, the size of the network capacity of the first device is proportional to the priority level. I.e. the higher the network capacity of the first device the higher the priority. The network capacity includes: the maximum number of users that can be successfully accessed in unit time, the maximum number of RRC active connection users supported in unit time (the number of RRC active connection users refers to the number of users performing data transmission at least once in unit time), the maximum number of users that can be scheduled in unit time, and the maximum number of users that can be served in unit time, where the unit time may be 1ms, 1s, or 1 day. Wherein the network capacity of the first device comprises any one of:
a ratio of a minimum allocatable radio resource to a minimum scheduling unit in the first device;
a network capacity of radio resources allocable in the first device; such as the network capacity corresponding to the unit resource allocable in the first device.
As another alternative embodiment, in the case that the reference information of the first device includes a frequency resource utilization rate of the first device, step 12 includes:
comparing the resource utilization rate of the first equipment with a first threshold value and a second threshold value of the first equipment respectively; wherein the first threshold value is less than the second threshold value;
according to the comparison result, determining the second equipment which can use the wireless resource currently;
the first device may release the occupation of the wireless resource or does not request to occupy the wireless resource when the resource utilization rate of the first device is lower than a first threshold value; when the resource utilization rate of the first device is higher than the first threshold and lower than the second threshold, the first device keeps the current state (for example, the device occupying the wireless resource keeps the occupied state and does not release the occupation of the wireless resource; for another example, the device not requesting to occupy the wireless resource keeps the current state and does not request to occupy the wireless resource); in case the resource utilization of the first device is higher than the second threshold, the first device may keep occupying the radio resource or request to occupy the radio resource.
In the embodiment of the invention, each first device is configured with two frequency resource utilization rate thresholds, namely a release resource utilization rate threshold and a recovery resource utilization rate threshold. Setting a first threshold value of the system 1 (Thresh1 System 1) and a second threshold value of the system 1 (Thresh2 System 1) as the system 1; the system 2 sets a first threshold value of the system 2 (Thresh1 system 2) and a second threshold value of the system 2 (Thresh2 system 2); wherein, the first threshold value corresponding to the same first device is smaller than the second threshold value; the resource utilization rate of the first device is max (uplink resource utilization rate, downlink resource utilization rate), and the actual resource utilization rate may be adopted.
If the resource utilization rate of the system 1 is less than or equal to the second threshold value of the system 1 (Thresh2 system 1), the system 1 maintains the current status;
if the resource utilization rate of the system 1 is greater than the second threshold value of the system 1 (Thresh2 system 1), sending a resource request message, applying for using the wireless resource of the system 2:
if the resource utilization rate of the system 2 is lower than a first threshold value of the system 2 (Thresh1 system 2), the system 2 releases the occupied wireless resources to the system 1 for use;
if the resource utilization rate of the system 2 is greater than or equal to the first threshold value of the system 2 (Thresh1 system 2), the radio resources occupied by the system 2 cannot be released.
Example 2: when 4G and 5G share the spectrum, 5G sets a first threshold value of 5G (i.e. the release PRB utilization threshold, or Thresh 15G) and a second threshold value of 5G (i.e. the retraction PRB utilization threshold, or Thresh 25G), and 4G sets a first threshold value of 4G (i.e. the release PRB utilization threshold, or Thresh 14G) and a second threshold value of 4G (i.e. the retraction PRB utilization threshold, or Thresh 24G). If the utilization rate of the 5G frequency resource is greater than Thresh 25G, the first device will be informed to request to use the wireless resource. If the utilization rate of the 4G frequency resources is lower than Thresh 14G, the 4G needs to release the wireless resources to the 5G for use; if the utilization rate of the 4G PRB is greater than or equal to Thresh 14G, the wireless resources occupied by the 4G are not releasable. Otherwise, if the 4G PRB utilization is greater than Thresh 24G, the first device will be notified to request use of radio resources. If the utilization rate of the 5G PRB is lower than Thresh 15G, the 5G needs to release the wireless resources to the 4G for use; if the utilization rate of the 5G PRB is greater than or equal to Thresh 15G, the wireless resources occupied by the 5G PRB cannot be released. Here, the PRB utilization rate is max (uplink PRB utilization rate, downlink PRB utilization rate), and the actual PRB utilization rate is adopted.
It should be noted that the first device is not limited to a base station, a base station controller BSC, a distribution unit DU, a central controller, a core network element, a central unit CU, an OMC (operation and management center), a network management server, an edge computing server, and the like, and is not limited herein.
As described above, after determining the second device that can currently use the radio resource, if the use of the radio resource changes (preemption or release), the other devices are notified of the relevant information.
Correspondingly, the method further comprises the following steps:
transmitting a first decision result to the determined second device that currently can use the radio resource, the first decision result including at least one of:
an indication of occupancy of radio resources;
the initial time and duration of occupancy;
start time and end time of occupancy.
Alternatively, the method further comprises:
and sending a second decision result to the equipment occupying the wireless resources, wherein the second decision result comprises a release instruction of the wireless resources.
Alternatively, the method further comprises:
and when the use of the wireless resource is changed, sending the changed use information of the wireless resource to a device capable of occupying the wireless resource.
Optionally, the first device and the decision device are deployed as a common device; alternatively, the first device and the decision device are deployed on different devices. When the first device and the decision device are deployed together, the request use of the wireless resource and the interaction of the decision result are completed through the signal message in the device.
And when the first equipment and the decision equipment are different equipment, the application of the wireless resources and the interaction of the decision result are completed by transmitting the third message, the fourth message and the fifth message or the third message and the fourth message. For example, as shown in fig. 3, the specific interaction method is as follows:
a) the first equipment sends a third message to the decision-making equipment, wherein the third message carries a first request of wireless resources;
the protocol format of the transmission message includes but is not limited to SNMP between the network manager and the base station, X2AP between the base stations, S1AP between the core network and the base station, etc.
b) And after the decision device finishes the attribution judgment of the wireless resources, sending a fourth message to the first device.
The protocol format of the transmission message includes but is not limited to SNMP between the network manager and the base station, X2AP between the base stations, S1AP between the core network and the base station, etc.
The fourth message includes, but is not limited to, one or more of an indication of occupation or release of the radio resource, a start time and an occupation duration of the occupation, or a start time and an end time of the occupation.
c) The first device sends a fifth message to the decision device (this step is an optional step);
the protocol format of the transmission message includes but is not limited to SNMP between the network manager and the base station, X2AP between the base stations, S1AP between the core network and the base station, etc.
The fifth message includes, but is not limited to, one or more of an acknowledgement of the fourth message, a usage of the shared frequency band.
And the wireless resource judgment is completed, and the related equipment receives the use notice of the wireless resource. The device that successfully preempts the radio resource may newly establish a cell to use the shared frequency resource, or may expand the shared frequency to the frequency spectrum resource that may be used by the existing cell. The system in which the radio resource is preempted stops using the preempted radio resource.
As a further embodiment, prior to step 11, the method further comprises:
the sharable radio resources and the dedicated resources of each first device are configured according to the total resources and the maximum bandwidth required by the historical traffic of each first device.
The total resources can be divided into granularities according to the bandwidth and also can be divided into granularities according to the resource blocks; different systems of different wireless access systems can share wireless resources in a time division multiplexing and frequency division multiplexing mode.
It should be noted that the first device for configuring the radio resource and the first device for determining the usage right of the radio resource may be deployed together with the device, or may be deployed on different devices, which is not specifically limited herein.
It is further to be noted that the first device and the decision device are deployed as a common device; alternatively, the first device and the decision are deployed on different devices.

Suppose there are 2 systems, the total resource is represented by S, the maximum resource required by each system is represented by M1, M2, the dedicated resource of each system is represented by N1, N2, and the sharable radio resource is represented by X (assuming that M1+ M2 is greater than S, if the condition is not satisfied, it is said that the current total resource is enough for 2 systems, no sharable radio resource is needed; M1\ M2 is less than S, if the condition is not satisfied, it is said that the current total resource cannot satisfy the system requirement, and capacity should be expanded; M1 >: M2). First, a sharable radio resource X is determined, and then N1 ═ M1-X and N2 ═ S-X-N1, taking one value in the (MI + M2-S, M1) interval. For example, 4G and 5G are co-deployed at 2515MHz-2635 MHz. The available frequency bandwidth amounts to 120M, the maximum bandwidth of 4G requires 60M and the maximum bandwidth of 5G requires 100M according to the historical traffic. Dedicated resources 20M are allocated for 4G, dedicated resources 60M are allocated for 5G, and sharable radio resources 40M. The dedicated resources cannot be shared and can only be used for a certain system, and the minimum performance of the system is maintained. The sharable radio resource may be shared between the 4G and 5G systems.
Example 4
Suppose there are 3 systems, the total resource is represented by S, the maximum resource required by each system is represented by M1, M2, M3, the dedicated resource of each system is represented by N1, N2, N3, and the sharable radio resource is represented by X (assume that M1+ M2+ M3 is greater than S, if the condition is not satisfied, the current total resource is enough for three systems to use, and no sharable radio resource is needed; M1\ M2\ M3 is less than S, if the condition is not satisfied, the current total resource cannot satisfy the system requirement, and the capacity should be expanded; M1> -M2 > -M3). Firstly, determining sharable wireless resources, and calculating an intermediate result of Y ═ MI + M2+ M3-S)/2, if M1\ M2\ M3 are all larger than Y, then the wireless resources X take one value in the (Y, M1) interval, then N1 ═ M1-X, N2 ═ M2-X, N3 ═ S-X-N1-N2; on the contrary, the sharable radio resource X takes one value in the interval (2Y-M3, M1), and then N1 ═ M1-X, N2 ═ M2-X, N3 ═ S-X-N1-N2. For example, the three communication systems GSM, NB-IoT and LTE are currently co-deployed at 935MHz-949 MHz. The total available frequency bandwidth is 15M, according to the historical traffic, the GSM maximum bandwidth needs 9M, the LTE maximum bandwidth needs 10M, and the NB-IoT maximum bandwidth needs 3M. Dedicated resources 4M are allocated for GSM, dedicated resources 5M are allocated for LTE, dedicated resources 1M are allocated for NB-IoT, sharable radio resources 5M. The dedicated resources cannot be shared and can only be used for a certain system, and the minimum performance of the system is maintained. The sharable radio resources may be shared among GSM, NB-IoT, and LTE systems.
After the frequency planning configuration is completed, when the first equipment and the decision equipment are deployed together, the interaction of the frequency spectrum configuration information is completed through signal information in the equipment; when the first device and the decision device are at different devices, the devices of the respective wireless communication systems are informed of the frequency configuration information by transmitting a sixth message or by a sixth message and a seventh message. For example, as shown in fig. 4, the specific method is as follows:
1) the decision device sends a sixth message to the first device;
the protocol format of the transmission message includes but is not limited to SNMP between the network manager and the base station, X2AP between the base stations, S1AP between the core network and the base station, etc.
The sixth message includes, but is not limited to, one or more of configuration information of the dedicated frequency resource and the sharable radio resource.
2) The first device sends a seventh message to the decision device (this step is an optional step);
the protocol format of the transmission message includes but is not limited to SNMP between the network manager and the base station, X2AP between the base stations, S1AP between the core network and the base station, etc.
One or more of an acknowledgement to the sixth message, dedicated frequency resources, and configuration information of sharable radio resources are included in the seventh message.
