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.
The embodiment of the invention discloses a method for distributing bandwidth resources, which is applied to a base station, wherein the base station sets the bandwidth resources set in a broadband and narrowband converged communication system as shared bandwidth resources;
specifically, most of the existing broadband and narrowband converged communication systems allocate available bandwidth resources to a broadband communication system and a narrowband communication system, respectively. That is, in most of existing wideband-narrowband converged communication systems, only wideband communication resources for wideband communication and narrowband communication resources for narrowband communication exist, and in order to prevent interference between the wideband communication system and the narrowband communication system, a guard interval is also reserved between the wideband communication system and the narrowband communication system, and bandwidth resources in the guard interval are idle bandwidth resources and are not used for communication.
However, since the traffic of the broadband communication system and the narrowband communication system varies at any time, the fixed bandwidth resource allocation cannot completely adapt to the bandwidth resource requirements of the broadband communication system and the narrowband communication system that vary at any time.
In order to solve the above problem, in the embodiment of the present invention, when allocating bandwidth resources to a broadband communication system and a narrowband communication system in a broadband and narrowband converged communication system, on the basis of allocating fixed bandwidth resources to the broadband communication system and the narrowband communication system, set bandwidth resources are reserved between the fixed bandwidth resources occupied by the broadband communication system and the narrowband communication system, respectively, as shared bandwidth resources. The specific bandwidth resource allocation is shown in fig. 1. The shared bandwidth resource can be temporarily occupied when the bandwidth resources of the broadband communication system and the narrowband communication system cannot meet the service requirement.
It should be noted that the setting of the bandwidth size of the shared bandwidth resource can be flexibly set according to the size of the available bandwidth resource, the system traffic, and other factors.
Based on the above bandwidth resource division basis, referring to fig. 2, the method for allocating bandwidth resources disclosed in the embodiment of the present invention specifically includes:
s201, respectively detecting whether the frequency spectrum utilization rate of each communication system in the broadband and narrowband integrated communication system exceeds a set threshold;
specifically, the base station applying the technical scheme of the embodiment of the invention has a spectrum sensing function and can detect the bandwidth utilization rate of the system in real time. When the broadband communication system and the narrowband communication system in the broadband and narrowband converged communication system perform normal communication services, the base station detects the frequency spectrum use conditions of the broadband communication system and the narrowband communication system respectively, that is, detects the bandwidth utilization rate of each system. Meanwhile, the base station sets a spectrum utilization threshold for each communication system (the broadband communication system and the narrowband communication system) in the broadband-narrowband converged communication system, and when the spectrum utilization of the communication system exceeds the set threshold, corresponding measures need to be taken.
It should be noted that the size of the spectrum utilization threshold can be flexibly set according to the service condition of the communication system, and is favorably set to 80%, 90%, 100%, and the like of the total spectrum.
When detecting that the spectrum utilization rate of any communication system exceeds the set threshold, step S202 is executed to allocate the set bandwidth resource in the shared bandwidth resources to the communication system whose spectrum utilization rate exceeds the set threshold.
Specifically, when the base station detects that the frequency spectrum utilization rate of any communication system (a broadband communication system or a narrowband communication system, or both the broadband communication system and the narrowband communication system) in the broadband and narrowband converged communication system exceeds a frequency spectrum utilization rate threshold set for the communication system, the base station allocates a part of bandwidth resources in the shared bandwidth resources to the communication system whose frequency spectrum utilization rate exceeds the set frequency spectrum utilization rate threshold, so as to ensure smooth service of the communication system.
For example, if the base station detects that the spectrum utilization rate of the narrowband communication system has exceeded the spectrum utilization rate threshold set for the base station, the base station allocates a part of the bandwidth resources in the shared bandwidth resources to the narrowband communication system to expand the bandwidth of the narrowband communication system, and ensure that the service of the narrowband communication system is normally performed.
It should be noted that, after allocating the bandwidth resource in the shared bandwidth resource to the required communication system, the base station may further allocate the shared bandwidth resource to the communication system according to the bandwidth requirement of the communication system under the condition that the shared bandwidth resource is allowed.
By adopting the method for allocating the bandwidth resources, provided by the embodiment of the invention, the base station sets the bandwidth resources set in the broadband and narrowband integrated communication system as shared bandwidth resources; when communication service is carried out, the base station respectively detects whether the frequency spectrum utilization rate of each communication system in the broadband-narrowband converged communication system exceeds a set threshold; and when detecting that the frequency spectrum utilization rate of any communication system exceeds a set threshold value, allocating the set bandwidth resource in the shared bandwidth resources to the communication system of which the frequency spectrum utilization rate exceeds the set threshold value. By implementing the technical scheme, the base station realizes that the narrow band communication system and the broadband communication system flexibly share the bandwidth resources on the basis that the narrow band communication system and the broadband communication system respectively have fixed bandwidth resources, and further improves the frequency spectrum utilization rate of the wide-narrow band fusion communication system.
Optionally, in another embodiment of the present invention, referring to fig. 3, when it is detected that the spectrum utilization rate of any communication system exceeds a set threshold, the method further includes:
s302, detecting whether idle bandwidth resources exist in the shared bandwidth resources;
if the shared bandwidth resources include idle bandwidth resources, step S303 is executed to allocate the set bandwidth resources in the idle bandwidth resources to the communication system whose spectrum utilization exceeds the set threshold.
Specifically, in the embodiment of the present invention, the shared bandwidth resource set by the base station in the narrowband and wideband converged communication system may be occupied by both the narrowband communication system and the wideband communication system. Thus, when one of the communication systems needs to occupy the shared bandwidth resource, it is likely that the shared bandwidth resource is already occupied by the other communication system, resulting in insufficient free shared bandwidth resource being available for allocation to the communication system. Therefore, in order to ensure successful allocation of the shared bandwidth resources, in the embodiment of the present invention, when it is detected and confirmed that the spectrum utilization rate of a certain communication system exceeds the spectrum utilization rate threshold, whether idle bandwidth resources exist in the shared bandwidth resources is detected, and if idle bandwidth resources exist, a part of the idle bandwidth resources is allocated to the communication system whose spectrum utilization rate exceeds the set threshold.
Step S301 in this embodiment corresponds to step S201 in the method embodiment shown in fig. 2, and for the specific content, please refer to the method embodiment shown in fig. 2, which is not described herein again.
Optionally, in another embodiment of the present invention, referring to fig. 4, if there is no idle bandwidth resource in the shared bandwidth resource, step S404 is executed to determine the priority of the service occupying the shared bandwidth resource and the service of the communication system whose spectrum utilization exceeds the set threshold;
if the priority of the service of the communication system with the spectrum utilization rate exceeding the set threshold is higher than the priority of the service occupying the shared bandwidth resource, step S405 is executed to terminate the service occupying the shared bandwidth resource and to detect whether there is idle bandwidth resource in the shared bandwidth resource again.
Specifically, if the spectrum utilization rate of a certain communication system in the narrowband and wideband converged communication system exceeds the spectrum utilization rate threshold, bandwidth resources in the shared bandwidth resources need to be allocated to the certain communication system, so as to ensure that the communication system performs service communication smoothly. When the base station detects that no idle bandwidth resource exists in the shared bandwidth resource, the base station further compares the service occupying the shared bandwidth resource with the priority of the service of the communication system with the frequency spectrum utilization rate exceeding the set threshold, and if the priority of the service of the communication system with the frequency spectrum utilization rate exceeding the set threshold is higher than the priority of the service occupying the shared bandwidth resource, the base station terminates the service occupying the shared bandwidth resource so as to vacate the idle bandwidth resource from the shared bandwidth resource.
And after the base station terminates the service occupying the shared bandwidth resources, re-detecting whether idle bandwidth resources exist in the shared bandwidth resources, and if the idle bandwidth resources exist, allocating a part of the idle bandwidth resources to the communication system with the frequency spectrum utilization rate exceeding the set threshold.
Steps S401 to S403 in this embodiment correspond to steps S301 to S303 in the method embodiment shown in fig. 3, and for details, please refer to the contents of the method embodiment shown in fig. 3, which is not described herein again.
Optionally, in another embodiment of the present invention, if the priority of the traffic of the communication system whose spectrum utilization exceeds the set threshold is not higher than the priority of the traffic occupying the shared bandwidth resource, whether there is a free bandwidth resource in the shared bandwidth resource is re-detected.
Specifically, when the base station detects that the frequency spectrum utilization rate of a certain communication system exceeds a utilization rate threshold, it detects whether idle bandwidth resources exist in shared bandwidth resources, and if it detects that idle bandwidth resources do not exist in the shared bandwidth and can be allocated to the system, and determines that the service priority of the communication system is not higher than the service priority of the shared bandwidth resources being occupied, the base station cannot allocate bandwidth resources in the shared bandwidth resources to the communication system. At this time, the base station re-detects whether there is an idle bandwidth resource in the shared bandwidth resource, when the service occupying the shared bandwidth resource is finished, there may be an idle bandwidth resource in the shared bandwidth resource, and at this time, the base station may timely detect that there is an idle bandwidth resource in the shared bandwidth resource, and allocate a bandwidth resource in the shared bandwidth resource to the communication system.
Optionally, in another embodiment of the present invention, after the base station allocates a set bandwidth resource in the shared bandwidth resources to the communication system whose spectrum utilization exceeds a set threshold, the method further includes:
when the frequency spectrum utilization rate of the communication system with the frequency spectrum utilization rate exceeding the set threshold value is detected not to exceed the set threshold value, or when the time that the communication system with the frequency spectrum utilization rate exceeding the set threshold value occupies the set bandwidth resource in the shared bandwidth resources exceeds the set time, controlling the communication system with the frequency spectrum utilization rate exceeding the set threshold value not to occupy the set bandwidth resource in the shared bandwidth resources.
Specifically, in the embodiment of the present invention, the base station is configured to continuously detect the frequency spectrum utilization rate of the communication system, and when the shared bandwidth resource is allocated to the communication system whose frequency spectrum utilization rate exceeds the frequency spectrum utilization rate threshold, the base station continues to continuously detect the frequency spectrum utilization rate of the communication system, and detects the duration of the shared bandwidth resource occupied by the communication system. When the frequency spectrum utilization rate of the communication system is lower than the frequency spectrum utilization rate threshold value, or the time length of the communication system occupying the shared bandwidth resource exceeds the set time length, the base station controls the communication system not to occupy the bandwidth resource in the shared bandwidth resource any more, so that each system in the broadband-narrowband converged communication system has an opportunity to occupy the shared bandwidth resource.
Optionally, in another embodiment of the present invention, the method further includes:
a base station divides bandwidth resources in shared bandwidth resources into narrow-band shared bandwidth resources and broadband shared bandwidth resources, and a guard interval is arranged between a narrow-band shared frequency band and a broadband shared frequency band; wherein the narrowband shared bandwidth resource is for allocation to a narrowband communication system; the broadband shared bandwidth resource is for allocation to a broadband communication system.
Specifically, in the embodiment of the present invention, on the basis of setting the shared bandwidth resource in the bandwidth resources of the narrowband and wideband converged communication system, the base station further divides the bandwidth resources in the shared bandwidth resource into the narrowband shared bandwidth resource and the wideband shared bandwidth resource, and the specific division method is shown in fig. 5. The narrow-band shared bandwidth resource is used for being allocated to the narrow-band communication system for use when the frequency spectrum utilization rate of the narrow-band communication system exceeds a frequency spectrum utilization rate threshold value; the broadband shared bandwidth resource is used for being allocated to the broadband communication system for use when the spectrum utilization rate of the broadband communication system exceeds a spectrum utilization rate threshold value. Meanwhile, in order to avoid mutual interference when the narrow-band communication system and the broadband communication system occupy the shared bandwidth resource at the same time, when the base station divides the narrow-band shared bandwidth resource and the broadband shared bandwidth resource in the shared bandwidth resource, a guard interval is set between the narrow-band shared bandwidth resource and the broadband shared bandwidth resource. The guard interval is a free bandwidth resource and is not used for communication traffic.
