Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative work are within the scope of the present invention.

The embodiment of the invention discloses a method for allocating bandwidth resources, which is applied to a base station, and the base station sets a bandwidth resource set in a wide-narrowband converged communication system as a shared bandwidth resource;

Specifically, most of the existing wide and narrowband converged communication systems allocate available bandwidth resources to the broadband communication system and the narrowband communication system. That is to say, in most of the existing wide and narrowband converged communication systems, there are only broadband communication resources for broadband communication and narrowband communication resources for narrowband communication, in order to prevent interference between the broadband communication system and the narrowband communication system. A guard interval is also reserved between the broadband communication system and the narrowband communication system, and the bandwidth resource in the protection interval is an idle bandwidth resource and is not used for communication.

However, since the traffic of the broadband communication system and the narrowband communication system changes at any time, the fixed bandwidth resource allocation cannot fully adapt to the bandwidth resource requirements of the broadband communication system and the narrowband communication system at any time.

In order to solve the above problem, the embodiment of the present invention allocates bandwidth resources for the broadband communication system and the narrowband communication system in the wide-narrowband fusion communication system, and allocates fixed bandwidth resources for the broadband communication system and the narrowband communication system, and performs broadband communication. Between the fixed bandwidth resources occupied by the system and the narrowband communication system, the set bandwidth resources are reserved as the shared bandwidth resources. The specific bandwidth resource allocation is shown in Figure 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 requirements.

It should be noted that the setting of the bandwidth size of the shared bandwidth resource can be flexibly set according to factors such as the size of the available bandwidth resources and the system traffic.

Based on the foregoing bandwidth resource division basis, as shown in FIG. 2, the method for allocating bandwidth resources disclosed in the embodiment of the present invention specifically includes:

S201. Detect whether a spectrum utilization rate of each communication system in the wide-narrowband fusion communication system exceeds a set threshold respectively.

Specifically, the base station to which the technical solution of the embodiment of the present invention is applied is provided with a spectrum sensing function, which can detect system bandwidth utilization in real time. When the broadband communication system and the narrowband communication system in the wideband and narrowband converged communication system perform normal communication services, the base station detects the spectrum usage of the broadband communication system and the narrowband communication system, that is, detects the bandwidth utilization of each system. At the same time, the base station separately sets the spectrum utilization threshold for each communication system (the broadband communication system and the narrowband communication system) in the wide-narrowband fusion communication system, and when the spectrum utilization rate of the communication system exceeds the set threshold, it is necessary to respond accordingly. Measures.

It should be noted that the size of the spectrum utilization threshold can be flexibly set according to the communication system service condition, and is advantageously set to 80%, 90%, 100% of the total spectrum.

When it is detected that the spectrum utilization of the arbitrary communication system exceeds the set threshold, step S202 is performed to allocate the set bandwidth resource in the shared bandwidth resource to the communication system whose spectrum utilization exceeds the set threshold.

Specifically, when the base station detects that any communication system in the wide-narrowband converged communication system (the broadband communication system or the narrowband communication system, or the broadband communication system and the narrowband communication system simultaneously) has a spectrum utilization ratio exceeding a spectrum utilization threshold set for it The base station allocates a part of the bandwidth resources in the shared bandwidth resource to the communication system whose spectrum utilization exceeds the set spectrum utilization threshold to ensure the traffic of the communication system is smooth.

For example, if the base station detects that the spectrum utilization of the narrowband communication system has exceeded the spectrum utilization threshold set for it, the base station allocates a part of the bandwidth resources of the shared bandwidth resource to the narrowband communication system to expand the bandwidth of the narrowband communication system. Ensure that the services of the narrowband communication system are normal.

It should be noted that after the base station allocates 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 and the shared bandwidth resource permitting. .

The method for allocating bandwidth resources according to the embodiment of the present invention, the base station sets the bandwidth resource set in the wide and narrowband converged communication system as the shared bandwidth resource; when the communication service is performed, the base station separately detects the wideband and narrowband converged communication system. Whether the spectrum utilization rate of each communication system exceeds a set threshold; when detecting that the spectrum utilization rate of any communication system exceeds a set threshold, allocating the set bandwidth resources in the shared bandwidth resource to the spectrum utilization exceeding A threshold communication system. By implementing the above technical solution, the base station realizes flexible sharing of bandwidth resources of the narrowband communication system and the broadband communication system on the basis of the fixed bandwidth resources of the narrowband communication system and the broadband communication system, respectively, and further improves the spectrum utilization ratio of the wideband and narrowband fusion communication system. .

Optionally, in another embodiment of the present invention, as shown in FIG. 3, when it is detected that the spectrum utilization rate of any communication system exceeds a set threshold, the method further includes:

S302. Detect whether there is an idle bandwidth resource in the shared bandwidth resource.

If there is an idle bandwidth resource in the shared bandwidth resource, step S303 is performed to allocate the set bandwidth resource in the idle bandwidth resource to a communication system whose spectrum utilization exceeds a set threshold.

Specifically, in the embodiment of the present invention, the shared bandwidth resource set by the base station in the wideband and narrowband converged communication system can be simultaneously occupied by the narrowband communication system and the broadband communication system. Therefore, when one of the communication systems needs to occupy the shared bandwidth resource, it is likely that the shared bandwidth resource has been occupied by another communication system, resulting in insufficient free shared bandwidth resources to be allocated to the communication system. Therefore, in order to ensure that the shared bandwidth resource is successfully allocated, the embodiment of the present invention detects whether there is an idle bandwidth resource in the shared bandwidth resource, and if there is an idle bandwidth resource, when detecting that the spectrum utilization of the communication system exceeds the spectrum utilization threshold. Then, part of the bandwidth resources in the idle bandwidth resource are allocated to the communication system whose spectrum utilization exceeds the set threshold.

Step S301 in this embodiment corresponds to step S201 in the method embodiment shown in FIG. 2 . For details, refer to the method embodiment shown in FIG. 2 , and details are not described herein again.

Optionally, in another embodiment of the present invention, as shown in FIG. 4, if there is no idle bandwidth resource in the shared bandwidth resource, step S404 is performed to determine that the service that is occupying the shared bandwidth resource is used, and The priority of the traffic of the communication system whose spectrum utilization exceeds the set threshold;

If the priority of the service of the communication system that exceeds the set threshold is higher than the priority of the service that is occupying the shared bandwidth resource, step S405 is performed to terminate the occupying the shared bandwidth resource. The service, and re-detecting whether there is idle bandwidth resource in the shared bandwidth resource.

Specifically, if the spectrum utilization of a communication system in the wideband and narrowband converged communication system exceeds the spectrum utilization threshold, bandwidth resources in the shared bandwidth resource need to be allocated to ensure the communication system smoothly performs service communication. When the base station detects that there is no idle bandwidth resource in the shared bandwidth resource, the base station further compares the service that is occupying the shared bandwidth resource with the priority of the service of the communication system whose spectrum utilization exceeds the set threshold, if the spectrum utilization rate is used. If the priority of the service of the communication system exceeding the set threshold is higher than the priority of the service occupying the shared bandwidth resource, the base station terminates the service that is occupying the shared bandwidth resource, so as to free the idle bandwidth resource from the shared bandwidth resource.

After the base station terminates the service that is occupying the shared bandwidth resource, re-detects whether there is an idle bandwidth resource in the shared bandwidth resource, and if there is an idle bandwidth resource, allocates a part of the bandwidth resource in the idle bandwidth resource to the spectrum utilization exceeding a set threshold. Communication system.

Steps S401 to S403 in this embodiment respectively correspond to the steps S301 to S303 in the method embodiment shown in FIG. 3 . For details, refer to the content of the method embodiment shown in FIG. 3 , and details are not described herein again.

Optionally, in another embodiment of the present invention, if the priority of the service of the communication system whose spectrum utilization exceeds the set threshold is not higher than the priority of the service that is occupying the shared bandwidth resource, Then, it is re-detected whether there is an idle bandwidth resource in the shared bandwidth resource.

Specifically, when the base station detects that the spectrum utilization of a communication system exceeds the utilization threshold, it detects whether there is an idle bandwidth resource in the shared bandwidth resource, and if there is no idle bandwidth resource in the detected shared bandwidth, the system can be allocated to the system, and the determination is confirmed. The service priority of the communication system is not higher than the service priority of the shared bandwidth resource, and the base station cannot allocate the bandwidth resource in the shared bandwidth resource to the communication system. At this time, the base station can detect the presence of the idle bandwidth resource in the shared bandwidth resource. When the service that is occupying the shared bandwidth resource ends, the shared bandwidth resource may have the idle bandwidth resource. Bandwidth resources, and allocating bandwidth resources in the shared bandwidth resources for the communication system.

Optionally, in another embodiment of the present invention, after the base station allocates the set bandwidth resource in the shared bandwidth resource to the communication system whose spectrum utilization exceeds a set threshold, the method further includes:

When it is detected that the spectrum utilization of the communication system whose spectrum utilization exceeds a set threshold does not exceed the set threshold, or the communication system that detects that the spectrum utilization exceeds a set threshold occupies the shared bandwidth resource When the time of the set bandwidth resource exceeds the set duration, the communication system that controls the spectrum utilization exceeding the set threshold no longer occupies the set bandwidth resource in the shared bandwidth resource.

Specifically, in the embodiment of the present invention, the base station is continuously configured to continuously detect the spectrum utilization rate of the communication system, and after the shared bandwidth resource is allocated to the communication system whose spectrum utilization exceeds the spectrum utilization threshold, the base station continues to continuously detect the spectrum utilization of the communication system. Rate, and the length of time that the communication system occupies shared bandwidth resources. When the spectrum utilization of the communication system is lower than the spectrum utilization threshold, or the communication system occupies the shared bandwidth resource for longer than the set duration, the base station controls the communication system to no longer occupy the bandwidth resources in the shared bandwidth resource, so that the bandwidth is narrow and narrow. Each system in a converged communication system has an opportunity to occupy shared bandwidth resources.

Optionally, in another embodiment of the present invention, the method further includes:

The base station divides the bandwidth resource in the shared bandwidth resource into a narrowband shared bandwidth resource and a broadband shared bandwidth resource, and sets a guard interval between the narrowband shared frequency band and the broadband shared frequency band; wherein the narrowband shared bandwidth resource is used for allocation A narrowband communication system is provided; the broadband shared bandwidth resource is for distribution to a broadband communication system.

Specifically, in the embodiment of the present invention, the base station further allocates the bandwidth resource in the shared bandwidth resource into a narrowband shared bandwidth resource and a broadband shared bandwidth resource, based on the shared bandwidth resource in the bandwidth resource of the wideband and narrowband convergence communication system. See Figure 5 for the specific division method. The narrowband shared bandwidth resource is used when the spectrum utilization of the narrowband communication system exceeds the spectrum utilization threshold, and is allocated to the narrowband communication system; the broadband shared bandwidth resource is used when the spectrum utilization of the broadband communication system exceeds the spectrum utilization rate. The threshold is assigned to the broadband communication system for use. At the same time, in order to avoid mutual interference when the narrowband communication system and the broadband communication system occupy the shared bandwidth resources at the same time, the base station shares the narrowband shared bandwidth resource and the broadband shared bandwidth resource in the shared bandwidth resource, and shares the bandwidth resource and the broadband shared bandwidth resource in the narrowband. Set the guard interval between. The guard interval is an idle bandwidth resource and is not used for communication services.
