All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The following is a detailed description of the method for obtaining user equipment information in the present invention. Referring to FIG. 1, an embodiment of a method for obtaining user equipment information according to an embodiment of the present invention includes:

101. In the direct working mode DMO, the first user equipment UE acquires UE information in a preset range.

In this embodiment, in the DMO, the DMO refers to a single call or a group call that directly communicates between UEs without the participation of the cluster system. There are three main modes of DMO, the normal pass-through mode, the multi-hop relay pass-through mode, and the network-through pass-through mode. The ordinary straight-through refers to that the cluster terminals directly communicate with each other without any other devices participating in the same; the multiple relay through-pass mode is to expand the communication coverage by adding a relay on the basis of the ordinary through mode. There are two ways to select the multi-hop relay pass-through mode. One is to use a separate relay device, and the other is to add a relay function to each cluster terminal. The network-through pass-through mode refers to When the cluster terminal establishes a passthrough, the network participates. After the passthrough establishes, the network exits. This mode is used by the UE to initiate a direct mode request to the network, and then the network allocates radio resources and end-to-end encryption keys to the calling UE and the called UE. With straight-through function.

In the three modes of the DMO mentioned above, the first UE may obtain the UE information in the preset range in any mode, and the UE information may be specifically expressed in the form of a list, and the UE information includes The number of UEs in the preset range, the first UE may be a communication device such as a mobile phone or a walkie-talkie.

It should be noted that the preset range may be a preset fixed range, or may be a valid range in which the UE can communicate, and thus is not limited herein.

102. The first UE receives, by using one or more second UEs, UE information that is adjacent to the second UE.

In this embodiment, the first UE may receive UE information sent by one or more second UEs, and the second UE is a device that communicates with the first UE, and its functions and attributes are similar to the first UE.

The first UE and one or more second UEs may constitute a communication network, and the first UE can completely count the total number of UEs in the communication network. The second UE may be a device that directly communicates with the first UE, or may be in a communication connection with the first UE by using multiple second UEs.

103. The first UE determines, according to the UE information in the preset range and the UE information sent by the second UE, the total number of UEs in the communication range with the second UE.

In this embodiment, the first UE may determine the total number of UEs in the network according to the number of UEs in the preset range and the UE information sent by the second UE to the UE. The network is a network in which the first UE communicates with the second UE. Specifically, when DMO communication is performed between two UEs, the effective range of the signal transmitted by one UE is used as a preset range, and the number of UEs in the preset range is determined. At this time, the UE sends a signal to another UE within a preset range, and the UE that receives the signal is also in another preset range, and obtains the number of UEs in another preset range, and all UEs in the preset range may be The numbers are added to obtain the total number of UEs in the target network.

It should be noted that, in actual communication, there may be one or more transit UEs for transmitting and receiving signals between UEs, or direct communication between two UEs. Here, only direct communication between two UEs is possible. The situation is described, the target network is also only the network that communicates between the two UEs. If one or more transit UEs exist, the target network will be expanded, so it is not limited here.

The first UE acquires UE information within the first communicable range by searching for a packet switched dedicated channel PSDCH.

In this embodiment, the UE searches for a packet-switched dedicated channel (English name: packet switching dedicated channel, English abbreviation: PSDCH), and the UE may specifically be a DMO node device in the DMO network.

The PSDCH is implemented by using a packet switching technology. The UEs of the two communicating parties divide the data of the UE communication into a plurality of smaller data segments of equal length, and add necessary control information as data in front of each data segment. The header of the segment, each data segment with the header constitutes a group. The address sent by the packet is indicated in the header. When the switch receives the packet, it will forward the packet to the destination according to the address information in the header. This process is packet switching.

Therefore, when searching for the PSDCH, the number of UEs is determined according to information of different UEs carried by different data packets in the PSDCH.

In the embodiment of the present invention, a specific manner of acquiring UE information in a preset range is provided, and the UE information in the preset range may be acquired by searching the PSDCH. In this way, the feasibility of the scheme in practical application is improved, and the UE information is obtained by searching the PSDCH, which ensures the accuracy of the UE information and further increases the practicability of the scheme.

Specifically, if the UE1 can obtain the neighbor list of the UE1 by reading the PSDCH, where there are UE6, UE7, and UE0, the UE2 that communicates with the UE1 can also obtain the neighbor list of the UE2 by reading the PSDCH, and there are UE3, UE4, UE5, and UE0. At this time, UE2 sends the obtained neighbor list to UE1, and UE1 can calculate the total number of UEs in the communication range between UE1 and UE2, remove UE0 of the overlapping part, and obtain 6 UE6, UE7, UE3, UE4, UE5, and UE0. UE.

It can be understood that each UE has a certain distance between each other, and can be realized within a certain distance. Communication, and the closer the distance, the better the communication between UEs.

In this embodiment, the UE information that is adjacent to the second UE includes the second UE acquiring the UE information in the communicable range by searching the PSDCH.

UE information adjacent to the third UE.

Specifically, for example, the UE2 can obtain the neighbor list of the UE2 by reading the PSDCH, and there are UE8, UE4, UE5, and UE0, and the UE3 can also obtain the neighbor list of the UE3 by reading the PSDCH. If there are UE11, UE12, and UE13, UE3 will The three UEs are sent to the UE2, and the UE2 recalculates that there are 7 UEs in the communication range between the UE2 and the UE3, and the UE2 forwards the result to the UE1.

In addition, in the embodiment of the present invention, when acquiring the number of UEs in the preset range, the UE may also acquire the neighbor relationship of the UE, and the neighbor relationship between the UEs may be known to be adjacent in the preset range. The distance and the distance of the UE transmitting signal are determined by the distance. If the UE communication range is exceeded, the signal transmission cannot be performed, so that the scheme has greater practicability in practical applications.

Optionally, in the third optional embodiment of the method for obtaining user equipment information provided by the embodiment of the present invention, the first UE is configured according to the preset range. Before the UE information and the UE information sent by the second UE are determined to be the total number of UEs in the communication range with the second UE, the method may further include:

The first UE updates the UE information in the preset range within a preset time.

In this embodiment, the first UE may periodically update the UE information in the preset range within a preset time, that is, broadcast the information such as the number of UEs and the distance of the UE in a preset time.

It should be noted that the preset time can be set to five minutes, or ten minutes, or other specific fixed time, so it is not limited herein.

Further, in the embodiment of the present invention, before determining the total number of UEs in the target network, the method of periodically broadcasting the number of UEs in the preset range within a preset time is used to implement calculation of the total number of UEs in the target network. The number of periodically broadcasting UEs can avoid the impact due to network instability, resulting in an accurate number of UEs.

Optionally, based on the second optional embodiment corresponding to FIG. 1 above, the embodiment of the present invention provides In a fourth optional embodiment, the first UE determines, before the total number of UEs in the communication range with the second UE, according to the UE information in the preset range and the UE information sent by the second UE. It can also include:

In this embodiment, the first UE may update the UE information in the preset range within a preset time, or may determine whether the UE information in the preset range changes, and only update the UE information when the change occurs.

The change of the UE information may be triggered by an event change, for example, if a new UE joins the communication, or if the UE fails, the available UE is reduced, and these events may cause the UE information to change.

Further, in the embodiment of the present invention, the UE is configured to obtain the number of UEs in the preset range based on the time trigger, which provides another possible implementation manner for obtaining the number of UEs in the solution of the present invention, and improves the feasibility of the solution.

Optionally, in the fifth optional embodiment of the method for acquiring user equipment information provided by the embodiment of the present invention, after the first UE acquires the UE information in the preset range, It can also include:

The first UE sends the UE information in the preset range to the second UE.

In this embodiment, the first UE may further send the UE information that is acquired by the UE to the second UE, where the UE information is determined according to the location of the first UE, and the UE information in the preset range is determined, and the UE information is sent. After the second UE, the second UE is also obtained with the UE information, and the total number of UEs in the network can also be obtained.

Secondly, in the embodiment of the present invention, the UEs can mutually transmit the UE information acquired by the UEs, determine the total number of UEs in the communication network by means of information interaction, and improve the feasibility and practicability of the scheme.
