The specific application scenario of the present invention is as follows. With the continuous development of Wireless communication Technology, Wireless Technology is moving from the 2-Generation Wireless Telephone Technology (2G) to the 4th Generation mobile communication Technology (4G), and is moving towards the 5th-Generation mobile communication Technology (5G). Also, the trunking communication technology is evolving from analog systems to narrowband digital trunking systems, and broadband digital trunking systems. With the increasing demand of industrial users for wireless broadband, the broadband digital trunking system is developed from the former simple voice trunking to the digital trunking communication system represented by LTE, which is divided into LTE of Time Division Duplex (TDD) system and LTE of Frequency Division Duplex (FDD) system. The narrowband digital trunking system is also called a narrowband communication network or a narrowband communication system, and the broadband digital trunking system is also called a broadband communication network or a broadband communication system, the narrowband communication network is, for example, a PDT network, a TETRA network, and the like, and the broadband communication network is, for example, an LTE network, a 5G network, and the like.
In the wireless communication technology, the most important and fundamental is the wireless spectrum resource, and now most of the spectrum resources below 1GHz are already allocated to the narrow-band communication network, so that it is difficult to allocate a wider section of spectrum resources suitable for the narrow-band communication network. For example, fig. 2 shows a first distribution diagram of spectrum resources in the prior art, fig. 3 shows a second distribution diagram of spectrum resources in the prior art, and the current spectrum resource distribution is as shown in fig. 2 and fig. 3, where spectrum resources in the range of 300MHz-328.6MHz are distributed to the aviation mobile field for communication, spectrum resources in the range of 328.6MHz-335.4MHz are distributed to the aviation radio navigation field for communication, and spectrum resources in the range of 403MHz-404.5MHz are distributed to the professional interphone field for communication; the newly added spectrum resource of WRC07IMT2000 in fig. 3 is a spectrum resource for telecommunications Union (ITU), where WRC in WRC07IMT2000 is a wireless Communication Conference (WRC), and IMT2000 is an International telephone Communication system 2000 (IMT 2000).
At present, spectrum resources provided by the public security field in China can be used for building various narrow-band communication networks, wherein a PDT (portable data processing) network is an important narrow-band communication network. The PDT network is mainly applied to the field of public security, and supports voice point calling, voice cluster and data services with small data volume. For example, the current spectrum resources are as follows: spectrum resources in the range of 336MHz-344MHz, which are used for public security image acquisition and can apply for continuous 4MHz or two discontinuous 2MHz, wherein 336MHz-340MHz is allocated to the limited use in the public security field; the public security dedicated 351MHz-356MHz spectrum resource for uplink transmission, or 361MHz-366MHz spectrum resource for downlink transmission 2x5MHz, is used in PDT network; 3MHz in spectrum resources within the range of 358MHz-361MHz is used for a single frequency point of a Direct Mode (DMO for short); the spectrum resource in the range of 1430MHz-1438MHz is used for communication of images special for the police helicopter and the unmanned aerial vehicle, for example, the spectrum resource required by the uplink flight control of the unmanned aerial vehicle is 840.5MHz-845 MHz; 1447MHz-1467MHz, is used for the current government broadband co-network frequency, and has no priority in the public security field. Fig. 4 is a diagram illustrating allocation of spectrum resources available in the public security domain in the prior art, and for the public security domain, the spectrum resources available in the public security domain are shown in fig. 4.
However, with the development of society, the demand for establishing a broadband communication network supporting multimedia fusion services such as pictures, videos, real-time positioning and the like and commanding and scheduling is more and more urgent, and the demand of services cannot be met by a narrow-band communication network. At present, a narrowband communication network needs to be evolved to a broadband communication network, for example, both a PDT network and a TETRA network need to be evolved to the broadband communication network, but most of spectrum resources below 1GHz are already allocated to a narrowband communication network system, and when the narrowband communication network is evolved to the broadband communication network, a wider spectrum resource suitable for the broadband communication network cannot be allocated to the broadband communication network, so that when there is no new spectrum resource which can be allocated to the broadband communication network, the broadband communication network cannot be established, and further, the evolution of the narrowband communication network to the broadband communication network cannot be realized. Further, how to use the existing spectrum resources to establish a broadband communication network, such as establishing an LTE network, and supporting media services such as telephone voice, trunked voice, multimedia message, Geographic Information System (GIS), video, data service, and command scheduling, is a problem that needs to be solved urgently.
The invention provides a network processing method and a network processing device, and aims to solve the technical problems in the prior art.
The following describes the technical solutions of the present invention and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 5 is a flowchart illustrating a network processing method according to an embodiment of the present application. As shown in fig. 1, the method includes:
In this embodiment, specifically, a narrowband spectrum resource used by a narrowband digital trunking system in the prior art is divided into two parts; one part is a first spectrum resource, the first spectrum resource is a spectrum resource used for establishing a broadband communication network, and the first spectrum resource comprises a bandwidth allocated to the broadband communication network to be established; the other part is a second spectrum resource, the second spectrum resource is a spectrum resource for establishing the narrow-band communication network, and the second spectrum resource comprises a bandwidth allocated to the narrow-band communication network to be established.
For example, the narrow Band Width (BW) of the existing PDT network is divided into LTE-BW for establishing the LTE network as the broadband communication network and PDT-BW for establishing the PDT network as the narrow Band communication network, wherein the spectrum resource is also referred to as a frequency bandwidth or a spectrum bandwidth resource.
For another example, the narrow-band spectrum resources of the existing TETRA network are divided into LTE-BW and TETRA-BW; the LTE-BW is used to establish an LTE network as a broadband communication network, and the TETRA-BW is used to establish a TETRA network as a narrowband communication network.
Other broadband communication networks and narrowband communication networks are suitable for use in the solution of the present embodiment.
And 102, establishing a broadband communication network according to the first frequency spectrum resource, and establishing a narrow-band communication network according to the second frequency spectrum resource.
In this embodiment, specifically, the broadband communication network is established according to the first spectrum resource, for example, the LTE network is established according to LTE-BW; at the same time, a narrowband communication network is established according to the second spectrum resource, e.g. a PDT network is established according to PDT-BW.
And 103, carrying the narrowband voice group carried by the carrier corresponding to the narrowband frequency spectrum resource, the data with the data volume smaller than the preset value and the voice cluster carried on the narrowband communication network on the broadband communication network.
In this embodiment, specifically, before step 101 is implemented, a narrowband voice group and small data are carried on a carrier corresponding to a narrowband spectrum resource used by a narrowband digital trunking system in the prior art, where the small data is data whose data size is smaller than a preset value, the small data is, for example, a status short message, a GIS positioning message, and the like, and the size of a single short message may be 48 bytes at most. Therefore, after step 102, the narrowband voice group and the small data carried by the narrowband spectrum resource corresponding to the carrier used by the narrowband digital trunking system in the prior art can be carried to the established broadband communication network, and the narrowband spectrum resource used by the narrowband digital trunking system in the prior art is absorbed to the established broadband communication network, so that the narrowband spectrum resource used by the narrowband digital trunking system in the prior art enters the spectrum resource of the established broadband communication network.
Data and voice groups and the like carried on the established narrowband communication network can also be carried on the established broadband communication network, because the spectral efficiency of the broadband communication network is higher than that of the narrowband communication network, and the broadband communication network with the same bandwidth can completely absorb voice clusters in the narrowband communication network.
For example, after the LTE network is established according to LTE-BW and the PDT network is established according to PDT-BW, data and voice groups etc. carried on the PDT network may be carried in the LTE network, and the LTE network may absorb the spectrum resources of the PDT network.
The present embodiment divides a narrowband spectrum resource into a first spectrum resource and a second spectrum resource, where the first spectrum resource includes a bandwidth allocated to a wideband communication network to be established, and the second spectrum resource includes a bandwidth allocated to the narrowband communication network to be established; establishing a broadband communication network according to the first frequency spectrum resource, and establishing a narrowband communication network according to the second frequency spectrum resource; and carrying the narrow-band voice group carried by the carrier corresponding to the narrow-band frequency spectrum resource, the data with the data volume smaller than the preset value and the voice cluster carried on the narrow-band communication network on the broadband communication network. Therefore, narrow-band spectrum resources in the prior art are divided into spectrum resources capable of establishing a broadband communication network and spectrum resources capable of establishing a narrow-band communication network, and the broadband communication network and the narrow-band communication network are respectively established; narrow-band voice groups and small data borne by a narrow-band frequency spectrum resource corresponding carrier wave used by a narrow-band digital trunking system in the prior art are borne on an established broadband communication network, and the narrow-band frequency spectrum resource used by the narrow-band digital trunking system in the prior art is absorbed on the established broadband communication network; then, data and voice groups and the like carried on the established narrowband communication network can be carried on the established broadband communication network, and the established broadband communication network can absorb the frequency spectrum resources of the established narrowband communication network; therefore, through the process, the frequency spectrum resources are distributed for the broadband communication network, the broadband communication network is established, the narrow-band frequency spectrum resources in the prior art can be gradually converted into the broadband frequency spectrum resources, and the evolution from the narrow-band communication network to the broadband communication network is further realized.
Fig. 6 is a flowchart illustrating another network processing method according to an embodiment of the present application. As shown in fig. 6, the method includes:
In an optional embodiment, the broadband communication network is an LTE network, and the narrowband communication network is a PDT network.
In this embodiment, specifically, this step may refer to step 101 in fig. 5, and is not described again.
Wherein, the broadband communication network is provided with an anchor carrier.
In this embodiment, specifically, the broadband communication network is established according to the first spectrum resource, for example, the LTE network is established according to LTE-BW, where the broadband communication network has an anchor carrier; at the same time, a narrowband communication network is established according to the second spectrum resource, e.g. a PDT network is established according to PDT-BW.
The narrowband speech group carried by the carrier corresponding to the narrowband frequency spectrum resource is a group which cannot be carried by the carrier corresponding to the second frequency spectrum resource after the narrowband frequency spectrum resource is divided into the first frequency spectrum resource and the second frequency spectrum resource; the data of which the data volume carried by the carrier corresponding to the narrowband frequency spectrum resource is smaller than the preset value is the data which cannot be carried by the carrier corresponding to the second frequency spectrum resource after the narrowband frequency spectrum resource is divided into the first frequency spectrum resource and the second frequency spectrum resource.
In this embodiment, specifically, before step 201 is implemented, a narrowband voice group and small data are carried on a carrier corresponding to a narrowband spectrum resource used by the narrowband digital trunking system in the prior art. After step 202, the narrowband spectrum resources used by the narrowband digital trunking system of the prior art, the carried narrowband voice groups and the small data, may be carried on the anchor carrier of the established broadband communication network. Furthermore, the narrowband voice groups and small data that cannot be carried due to the reduction of the bandwidth of the existing narrowband communication network can be carried on the wideband communication network established in this embodiment. Furthermore, the narrowband spectrum resources used by the narrowband digital trunking system in the prior art are absorbed to the established broadband communication network, so that the narrowband spectrum resources used by the narrowband digital trunking system in the prior art enter the spectrum resources of the established broadband communication network.
In this embodiment, specifically, a carrier of the established broadband communication network may be used as an anchor carrier, and data sent by the terminal is carried on the anchor carrier; or, the carrier of the established broadband communication network is used as an anchor carrier, other available frequency band resources are used as auxiliary other spectrum resources, data sent by the terminal is carried on the carrier corresponding to the other spectrum resources, and then the other spectrum resources are sent to a spectrum resource pool of the broadband communication network.
Specifically, when the terminal accesses the broadband communication network, the system message of the terminal is carried on an anchor carrier of the broadband communication network, and the terminal resides on the anchor carrier. Then, the broadband communication network may obtain terminal access information, where the terminal access information includes at least one of the following: the number of terminals, the link quality of the terminals, the traffic type of the terminals. Then, the broadband communication network can acquire the data sent by the terminal, then the broadband communication network carries out unified scheduling, and when the anchor point carrier is determined to meet the concurrent service requirement of the voice cluster, the broadband communication network allocates anchor point resources for the data sent by the terminal. The data for the terminal is then carried on the anchor carrier.
Or, when the terminal accesses the broadband communication network, the system message of the terminal is carried on the anchor carrier of the broadband communication network, and then the terminal resides on the anchor carrier. The broadband communication network may then obtain the terminal access information. Then, the broadband communication network may obtain data sent by the terminal, and then perform unified scheduling, where the broadband communication network allocates other spectrum resources to the data sent by the terminal, for example, the broadband communication network uses carriers that can be used and correspond to the other available spectrum resources to carry the data sent by the terminal, or the broadband communication network removes the data of the carriers that correspond to the other spectrum resources and then uses the carriers that correspond to the other spectrum resources to carry the data sent by the terminal. And further, carrying the data sent by the terminal on carriers corresponding to other spectrum resources. Therefore, the broadband communication network absorbs other spectrum resources and adds the other spectrum resources into the spectrum resource pool of the broadband communication network.
In the following, a broadband communication network is taken as an LTE network, and a narrowband communication network is taken as a PDT network.
Firstly, dividing narrow-band spectrum resources of a PDT network in the prior art into LTE-BW and PDT-BW, wherein the LTE-BW is used for establishing the LTE network as a broadband communication network, and the PDT-BW is used for establishing the PDT network as a narrow-band communication network; then the existing narrow-band spectrum resources are replanted. Fig. 7 is a schematic diagram illustrating the division of spectrum resources in another network processing method according to the embodiment of the present application, which is a first schematic diagram, as shown in fig. 7, a 2x5M narrowband spectrum resource B1 is divided into PDT-BW and LTE-BW, and the LTE-BW is configured to be 1.4M/3M/5M according to the frequency point usage of the existing PDT network. In fig. 7, uplink LTE FDD and downlink LTE FDD are included.
Then, fig. 8 is a schematic diagram illustrating the division of spectrum resources in another network processing method according to the embodiment of the present application, as shown in fig. 8, after acquiring data sent by a terminal or acquiring another voice group, another spectrum resource B2 in the range of 336 and 344MHz is added, and a part of spectrum resources of the other spectrum resource B2 is used for transmission of Single Uplink (SUL) data. In fig. 8, the partial spectrum resources of the other spectrum resource B2 may be allocated to 3M, 5M, or 8M according to actual situations. The established broadband communication network LET network can absorb the services carried on other spectrum resources B2 before replanting, and then other spectrum resources B2 are added into a spectrum resource pool of the LET network.
Next, fig. 9 is a schematic diagram illustrating the division of spectrum resources in another network processing method according to the embodiment of the present application, as shown in fig. 9, when the bandwidth of another spectrum resource B2 still cannot satisfy the data service, another spectrum resource B3 may be further added, where the range of B3 is 1430-1438 MHz. Some or all of the other spectrum resources B3 may be used for transmission of single-sideband uplink data. The established broadband communication network LET network can absorb the services carried on other spectrum resources B3 before replanting, and then other spectrum resources B3 are added into a spectrum resource pool of the LET network. By analogy, under the situation that other spectrum resources B3 still cannot meet the usage of the broadband service, other available spectrum resources may be added, and the spectrum resources may be uniformly scheduled and allocated by the anchor point carrier.
Optionally, other spectrum resources may also be added to the spectrum resource pool of the LET network in a carrier aggregation manner of FDD LTE or time TDD LTE, for example, and the spectrum resources may be uniformly controlled and scheduled by the anchor carrier. Fig. 10 is a schematic diagram illustrating the division of spectrum resources in another network processing method according to the embodiment of the present application, and as shown in fig. 10, spectrum resources such as 336-344MHz other spectrum resources B2, 1430-1438MHz other spectrum resources B3, 1447-1467MHz other spectrum resources B4 may be added to the spectrum resource pool of the LET network in a carrier aggregation manner.
In the above example process, since the PDT network adopts a 4-Frequency-shift keying (FSK for short) modulation method, when Frequency reuse of 12 is considered under the networking condition, the spectral efficiency of the PDT network is 0.048 bit/Hz; under the condition of co-frequency networking, the frequency reuse coefficient of the LTE network is 1, under the condition of SA0, the spectrum efficiency of the LTE network is about 1.25bit/Hz when Uplink (UL) is 0.766bit/Hz and Downlink (DL) is 0.49bit/Hz, and the average spectrum efficiency of the LTE network is 1.25 bit/Hz. Through the analysis, the voice trunking service of the PDT network can be completely borne on the LTE network, and the redundant LTE network capacity in the LTE network can be used for carrying data services when the voice trunking service is satisfied. Therefore, after the spectrum resources of the PDT network are gradually absorbed and the equipment of the PDT network is gradually replaced, the PDT-BW can be flexibly configured to be LTE-BW, and further, under the condition that the equipment of the LTE network is not replaced, the PDT-BW is completely replaced by the LTE-BW, and smooth transition and evolution from the PDT network to the LTE network are realized.
And step 205, the voice cluster carried on the narrowband communication network is carried on the broadband communication network.
In this embodiment, specifically, data and voice groups and the like carried on the established narrowband communication network may be carried on the established broadband communication network, because the spectral efficiency of the broadband communication network is higher than that of the narrowband communication network, and the broadband communication network with the same bandwidth may completely absorb voice clusters in the narrowband communication network.
The present embodiment divides a narrowband spectrum resource into a first spectrum resource and a second spectrum resource, where the first spectrum resource includes a bandwidth allocated to a wideband communication network to be established, and the second spectrum resource includes a bandwidth allocated to the narrowband communication network to be established; establishing a broadband communication network according to the first frequency spectrum resource, and establishing a narrowband communication network according to the second frequency spectrum resource; and carrying the narrow-band voice group carried by the carrier corresponding to the narrow-band frequency spectrum resource, the data with the data volume smaller than the preset value and the voice cluster carried on the narrow-band communication network on the broadband communication network.
