In general, the public and private convergence technical scheme uses two wireless modems, one of which is responsible for a public network and one of which is responsible for a private network, and each uses a set of radio frequency transceiver devices, namely a two-way wireless modem. However, this convergence scheme is significantly higher than the cost or power consumption required by a conventional LTE modem or an ad hoc network modem, both in terms of cost and power consumption.

Furthermore, some specific details are omitted from the description in order to avoid obscuring the invention.

This relative terminology is for convenience only and is not intended to be limiting of the invention as it is described in terms of the apparatus being manufactured or operated in a particular orientation.
It will be understood that, although the terms "first," "second," "third," etc. may be used herein to describe various elements, regions, layers and/or sections, these elements, regions, layers and/or sections should not be limited by these terms and these terms are merely used to distinguish between different elements, regions, layers and/or sections. Accordingly, a first component, region, layer, and/or section discussed below could be termed a second component, region, layer, and/or section without departing from some embodiments of the present invention.
In order to overcome the defects in the prior art, the invention provides a communication method and a device for single radio frequency integration of a public network and an ad hoc network, which adopt a time division mode to multiplex radio frequency resources, realize the high concentration and integration of the public network and the ad hoc network by only using a single radio frequency channel without additionally increasing the calculation cost required by baseband signal processing, and have outstanding advantages in the aspects of hardware volume, cost, power consumption and the like.
The communication devices in the present invention can be divided into two main categories, namely, a master device or a central node, and a slave device. In an embodiment, the technology is implemented for a master device similar to that used by a base station e-NodeB of LTE technology, and for a slave device similar to that used by an LTE terminal UE.
The LTE-like ad hoc network and the LTE public network have similar design concepts and frame structures: the four main functions of signal searching, synchronization holding (including neighbor cell measurement), random access and data interaction are completed through a synchronous channel, a control channel, an access channel and a data channel, so that the two functions can be fused with each other efficiently.
It should be noted that, the public network in this document adopts an LTE network, and the ad hoc network deploys the description of the method for single-radio-frequency fusion between the public network and the ad hoc network provided by the present invention in an LTE-like network system, so that the purpose is merely to better describe the flow of the method of the present invention, but not to limit the protection scope of the present invention, and in fact, other types of public networks and ad hoc networks are equally applicable to the method for single-radio-frequency fusion between the public network and the ad hoc network provided by the present invention, and all should be included in the protection scope of the present invention.
For a terminal residing in the LTE public network, the time requirements of the four functions of signal searching, synchronization maintaining, random access and data interaction for operating the radio frequency are different, so that a corresponding communication method can be formulated according to the different time requirements.
Fig. 1 is a method flow diagram of a communication method of single radio frequency integration of a public network and an ad hoc network according to an aspect of the present invention.
Referring to fig. 1, in a communication method of single radio frequency integration of a public network and an ad hoc network provided by the present invention, the method includes:
step 101: the public network search is initiated by the master device to camp on a cell in the public network.
After the main equipment is started, a public network protocol stack is started first to search the public network and reside the public network cell. The probability of occurrence of signal search is low, and radio frequency needs to be continuously operated in a short time.
Step 102: the primary device allocates first time domain resources according to time resources and repetition periods occupied by communication traffic of synchronization channels and common channels of the camping public network cell.
And the main equipment keeps the synchronization and paging receiving of the public network through the synchronization channel and the public channel of the public network cell. Since the time resources and repetition period of the synchronization channel and the common channel of the current LTE network have been obtained, the synchronization is kept to be periodical and predictable, and the time overhead is very small, for example, the duty ratio is smaller than 1/100 in the LTE network.
Step 103: the method comprises the steps that first reserved resources are reserved in a frame of an ad hoc network by a master device, the first reserved resources are obtained by mapping first time domain resources into the ad hoc network, and the first reserved resources do not conflict with communication services of the ad hoc network.
The mapping of the first reserved resources by the first time domain resources is performed by a mapping module in a baseband processing chip of the master device.
Step 104: and the master device sends a synchronizing signal and a broadcasting message in the ad hoc network to wait for the access of the slave device, the master device synchronizes the public network and receives the paging in the first time domain resource, and the master device and the slave device pause the data transceiving of the ad hoc network in the first reserved resource.
It can be appreciated that the communication service used for signal searching, synchronization and paging reception is predictable, and the required time domain resources are relatively fixed, so that corresponding time slots are reserved in the ad hoc network for the part of public network service, and the ad hoc network is ensured not to transmit and receive the service in the time slots so as to avoid conflict with the synchronous service of the public network.
Fig. 2 is a method flow diagram illustrating a communication method when a master device changes a camping cell according to an embodiment of the present invention.
As shown in fig. 2, in an embodiment, when the master device changes a public network resident cell, the communication method includes:
Step 201: triggering neighbor cell measurement by the master device during the period of camping on the original cell, and distributing second time domain resources according to neighbor cell configuration and measurement period obtained by the neighbor cell measurement.
The method comprises the steps that when resident cells are replaced in the public network, neighbor cell measurement is triggered firstly, so that second time domain resources are allocated according to configuration information measured by the neighbor cells, the second time domain resources are used for replacing resident cells in the public network by a main device, and the partial resources are relatively predictable.
Step 202: reserving second reserved resources in a frame of the ad hoc network by the main equipment, wherein the second reserved resources are obtained by mapping second time domain resources into the ad hoc network;
step 203: and broadcasting information of the second reserved resources in the ad hoc network by the master device to inform all devices in the ad hoc network to suspend data transceiving of the ad hoc network in the second reserved resources.
And in the second reserved resource, the ad hoc network pauses the data receiving and transmitting service so that the main equipment completes the cell replacement work in the public network. Since this fraction of time is often predictable and often very short, stopping the data transceiving operation of the ad hoc network during this fraction of time is also controllable for the communication reliability of the network as a whole.
Step 204: changing camping to a new cell by the master device; and
Step 205: the time domain resources needed for synchronization and paging reception in the resident public network cell are reserved in the ad hoc network by the master device.
Step 205 is similar to the step of reserving synchronization and paging time resources after camping on a cell when performing signal search, except that when replacing a camping cell, it is required to determine whether the synchronization time resource of a new cell conflicts with the service transceiving of the ad hoc network itself when performing slot reservation according to the synchronization time resource of the new cell.
Fig. 3 is a flowchart of a method for reserving domain resources for keeping synchronization of a public network resident cell and paging reception in an ad hoc network by a master device when the master device changes the resident cell according to an embodiment of the present invention.
As shown in fig. 3, in an embodiment, when the primary device changes camping cells, step 205 further comprises:
step 2051: in a new resident cell, after a first reserved resource is obtained by mapping a first time domain resource, the master device judges whether the first reserved resource conflicts with the current communication service of the ad hoc network;
step 2052: if the first reserved resource does not conflict with the current communication service of the ad hoc network, the master device allocates the first reserved resource in a frame of the ad hoc network and broadcasts the first reserved resource to all devices in the ad hoc network through a system message; and
Step 2053: if the first reserved resource conflicts with the current communication service of the ad hoc network, all devices in the ad hoc network are informed of adjusting the frame structure of the ad hoc network through a broadcast system message so as to avoid conflict, and then the master device allocates the first reserved resource in the frame of the ad hoc network.
In addition to signal searching and synchronization maintenance, network traffic also includes random access and data interaction for the public network.
Fig. 4 is a schematic diagram of a communication method when triggering a public network random access and data interaction service in a public network and ad hoc network single radio frequency convergence according to an embodiment of the present invention.
Referring to fig. 4, in an embodiment, the communication method of single radio frequency integration of public network and ad hoc network provided by the present invention further includes:
step 401: when triggering random access or data interaction service of the public network, the master equipment allocates a third time domain resource in a frame of the ad hoc network;
step 402: the master device judges whether an idle slave device exists in the current ad hoc network and whether a data request can be forwarded through the idle slave device; and
step 403: and processing the random access or data interaction service according to the judgment result.
Fig. 5 is a flowchart of a method for a master device to process a random access or data interaction service according to a determination result of whether there is an idle slave device according to an embodiment of the present invention.
Referring to fig. 5, in one embodiment, step 402: the master device determining whether there is an idle slave device in the current ad hoc network and whether the data request can be forwarded by the idle slave device, further comprising:
step 4021: responding to the existence of an idle slave device in the current ad hoc network and forwarding a data request through the idle slave device, and forwarding data of random access or data interaction service to a public network through the idle slave device by the master device; and
step 4022: and in response to the fact that no idle slave device exists in the current ad hoc network or the data request cannot be forwarded through the idle slave device in the ad hoc network, the master device broadcasts a notification to all devices in the ad hoc network to suspend the communication service of the ad hoc network so as to perform random access or data interaction service operation of the public network.
Since random access and data interaction generally occur continuously, radio frequency needs to be occupied continuously, and duration is unpredictable, as can be understood by those skilled in the art, if an idle slave device exists currently, the master device forwards the random access and data interaction service of the public network through the slave device, so that the master device does not need to suspend the communication service of the ad hoc network. Once the master device pauses the ad hoc communication service itself for public network service, the ad hoc communication service of all the slave devices in the ad hoc network will also pause. Therefore, the idle slave equipment is utilized to forward the public network service, so that the continuity of the ad hoc network service is ensured to a certain extent, and the availability of the communication network is improved.
It should be noted that, unlike signal searching, synchronization maintaining and neighbor cell measurement, the third time domain resource used by the master device for random access and data interaction in the public network does not map a corresponding time slot in the frame structure of the ad hoc network, but starts to determine whether there is an idle slave device currently once the third time domain resource exists in the master device, and processes or forwards the service according to the determination result.
In one embodiment, when all devices in the ad hoc network suspend the communication traffic of the ad hoc network, the master device still transmits the synchronization signal of the ad hoc network to keep the devices in the ad hoc network synchronized, and broadcasts in the ad hoc network whether to resume the communication traffic service of the ad hoc network.
Further, in an embodiment, when all devices in the ad hoc network suspend the communication service of the ad hoc network, the slave device periodically receives the ad hoc network synchronization signal sent by the master device to maintain synchronization, periodically listens to the broadcast message for recovering the ad hoc network communication service sent by the master device, and resumes the data transceiving of the ad hoc network in response to receiving the broadcast message for recovering the ad hoc network communication service.
The slave device receives the synchronization message of the master device and the broadcast message of whether to recover the ad hoc network service, which may be performed simultaneously or separately.
Preferably, in an embodiment, when all devices in the ad hoc network suspend the communication traffic of the ad hoc network, the master device forcedly preempts the radio frequency resource to transmit the synchronization signal, and broadcasts whether to resume the communication traffic service of the ad hoc network through the minimum broadcast channel.
The forced preemption of the radio frequency resource can keep the reliability of the synchronization of the equipment, and meanwhile, the minimum broadcast channel is adopted to broadcast the service recovery message, so that the power consumption loss of the equipment can be further reduced, the service performance is improved, and meanwhile, the data transmission of the ad hoc network can be rapidly continued after the service reply.
Because the communication method provided by the invention is characterized in that the ad hoc network and the public network are integrated and only one set of radio frequency transceiver equipment is used, the required technical schemes of the master equipment and the slave equipment are differentiated.
Fig. 6 is a flow chart of a method of slave device in a single rf converged communication method between public network and ad hoc network according to an embodiment of the present invention.
As shown in fig. 6, in an embodiment, for a slave device, a communication method includes:
step 601: the LTE protocol stack is normally started, and network searching and residence are performed;
step 602: the Ad hoc network protocol stack is normally started, searches for signals and resides; and
step 603: according to the principle that the control channel is prior to the service channel and the similar channels are obtained first, the LTE protocol stack and the Ad hoc network protocol stack perform radio frequency channel preemption, and double-standby single-pass is realized.
Although in the embodiment shown in fig. 6, the slave device starts the LTE protocol stack and then starts the ad hoc protocol stack, in practice, the starting sequence of the public network and the ad hoc protocol stack of the slave device is not limited. For the master device, the public network protocol stack must be started to reside in the public network cell, then the ad hoc network protocol stack is started, and the frame structure of the ad hoc network is configured according to the service time resource requirement in the public network. Therefore, for the slave device, the protocol stack opening sequence of the public network and the ad hoc network is not limited, but for the master device, the protocol stack of the public network is opened first and then the ad hoc network is opened.
The priority rules for the services are not limited to the slave devices, and in one embodiment, all communication services in the public network and the ad hoc network are performed according to the first-come first-get principles of control channels having priority over service channels, call services having priority over data services and similar channel services, and the master device and the slave device process the services according to the principles.
In an embodiment, the master device and the slave device are simultaneously located in a public network of a same network system provided by a same operator, and the network system includes TD-LTE and FDD-LTE.
In order to improve the integration efficiency of the ad hoc network and the public network, the slave device and the master device can reside on the same operator, and only one access mode of TD-LTE or FDD-LTE is used for residence according to the requirement of the master device. It should be noted that the present invention is applicable to different operators and to different network systems of TD-LTE or FDD-LTE. The above description is merely exemplary with respect to specific public network types or network system types, and is not intended to limit the scope of the present invention. The single-radio frequency fusion method of the public network and the self-organizing network is also applicable to other types of networks, but the technical scheme for fusing the public network and the self-organizing network communication service by adopting similar time division multiplexing is included in the protection scope of the invention.

Referring to fig. 7, in an embodiment, a master baseband processing chip 700 maps a predicted time slot requirement of a public network service in a public network protocol stack to a protocol stack of an ad hoc network through a requirement mapping module, and determines whether an idle slave device is satisfied for forwarding the public network service or not according to the predicted time slot requirement of the public network service, if the idle slave device is satisfied, the operation of the ad hoc network protocol stack is suspended, and if the idle slave device is not satisfied, the public network service is forwarded through the idle slave device. The predictable public network service comprises signal searching, neighbor cell measurement, synchronization maintenance and the like, and the unpredictable public network service comprises random access, data interaction and the like. Meanwhile, the corresponding radio frequency operation request is sent to the same radio frequency transceiver module for arbitration no matter the communication service in the public network or the communication service in the ad hoc network, and the communication signals are transmitted and received in a radio mode through the same radio frequency transceiver.
Fig. 8 is a functional logic diagram of a baseband processing chip of a slave device according to an embodiment of the present invention.
Referring to fig. 8, in an embodiment, after the public network protocol stack and the ad hoc network protocol stack are opened, the slave baseband processing chip 800 periodically maintains the synchronization of the ad hoc network by receiving the synchronization message of the master device, and if the operation of the ad hoc network is suspended, it also needs to periodically receive the broadcast message of the master device to know whether the ad hoc network resumes service, and if the broadcast message of resuming service is not received, it continues to periodically monitor the receiving and keep the synchronization. Meanwhile, similar to the master device, the corresponding radio frequency operation request is sent to the same radio frequency transceiver module for arbitration, and the communication signals are transmitted and received in a radio form through the same radio frequency transceiver, so that the communication service in the public network or the communication service in the ad hoc network can be realized.
