Background

In the trunking service, the Direct Mode Operation (DMO) technology is applied to the case of Direct communication between User equipments (ues) without cellular network coverage. Because there is no coverage of cellular network, there is no unified scheduling of base stations, and the time domain resources occupied by each UE transmission can only be pre-configured by the upper layer, or randomly selected by the UE itself, and in the network, the number of UEs directly determines the size of each UE configuration resource block.

In the prior art, a segment of time-frequency resources is statically allocated to each UE, and the UE can directly transmit on the resource block when transmitting.

However, as the number of UEs in the network increases, the number of resource blocks statically configured for each UE decreases, or as the number of UEs in the network decreases, the number of resource blocks statically configured for each UE increases, and at this time, if all UEs randomly select time-frequency resources without limitation, the probability of selecting time-frequency resources to cause collisions may be higher, so that the utilization rate of the time-frequency resources is reduced, and user experience is affected.

Detailed Description

The embodiment of the invention provides a resource allocation method and related equipment, which are used for improving the resource utilization rate and improving the user experience by allocating the number of resources in real time based on the number of UE (user equipment)

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.

Referring to fig. 1, a method for allocating resources in the present invention is described in detail below, and an embodiment of the method for allocating resources provided by the present invention includes:

101. determining the number of resources allocated to each UE according to the number of the first User Equipment (UE);

in this embodiment, the DMO is applied to a DMO, where the DMO refers to a single call or a group call in which UEs directly communicate with each other without participation of a cluster system. The network node device determines a number of resources allocated to each UE based on a first number of UEs, wherein the first number of UEs is an original number of UEs present in the network. The resource number may be a Resource Block (RB), where the RB is composed of 12 consecutive subcarriers, the bandwidth is 180kHz, the duration is 1ms, and 1 subframe has 2 slots. The number of RBs is related to the frequency bandwidth, for example, a 20MHz bandwidth has 100 RBs, and a 10MHz bandwidth has 50 RBs. The network node device may be a UE applied in a DMO mode, such as a mobile phone or an intercom.

In the following, a method for determining the number of resources allocated to each UE according to the first UE number will be specifically described, if there are 100 RBs in the 20MHz bandwidth, and 10 UEs are detected in the cell in the DMO mode. In this case, each UE may be divided into 10 RBs on average, or the number of RBs may be randomly allocated to each UE according to the prior art.

The method may be used as a rule preset by the network node device, and the rule is used to determine the number of resources of each UE.

102. When the change size of the first UE number exceeds a preset threshold, acquiring the changed UE number as a second UE;

in this embodiment, when the original number of UEs in the network changes and the changed number of UEs exceeds the preset threshold, the changed number of UEs, that is, the second number of UEs, needs to be obtained.

It should be noted that the preset threshold may be that the number of the first UE is increased or decreased by within 5, may also be that the number of the first UE is increased or decreased by within 10, and may also be a dynamic threshold value taking manner, for example, the number of the first UE is increased by one time or decreased by half, and the preset threshold may be taken according to the number of the first UE, so that the present disclosure is not limited herein.

103. And determining the number of resources allocated to each UE according to the second UE number.

In this embodiment, after the second number of UEs is obtained, the configuration of the static resources is updated. Determining the number of RBs allocated to each second UE according to the number of second UEs. Under the condition that the total RB number is not changed, if the number of the UE is increased, the configurable frequency domain RB number allocated to each UE is reduced; the number of frequency domain RBs allocated to each UE that is configurable may increase if the UE data decreases.

A method for determining the number of resources allocated to each UE according to the second number of UEs will be described in detail below: if there are 100 RBs in the 20MHz bandwidth and 10 UEs are detected in the cell in the DMO mode, after a period of time, 10 UEs are newly added, and at this time, there are 20 UEs in the cell. On the premise that the total number of RBs is not changed, 5 RBs can be obtained on average per UE.

Optionally, on the basis of the embodiment corresponding to fig. 1, in a first optional embodiment of the method for resource allocation provided in the embodiment of the present invention, acquiring the changed number of UEs as the second number of UEs may include:

and determining the number of second UE in the target network according to the number of the UE in the preset range.

In this embodiment, when the number of the first UEs changes and the size of the change exceeds a preset threshold, the network node device obtains the number of the UEs in a preset range, and determines the total number of the UEs in the target network according to the number of the UEs in the preset range, where the total number of the UEs in the target network is the second number of the UEs.

The network may be a network in a DMO mode, where DMO refers to a single call or a group call in which UEs directly communicate without participation of a cluster system. There are three main modes of DMO, a normal pass-through mode, a multi-hop relay pass-through mode, and a network-participating pass-through mode. The common direct connection means that the cluster terminals directly communicate with each other under the condition that no other equipment participates; the multi-relay direct mode is a direct mode for expanding the communication coverage by adding relays on the basis of a common direct mode, and the multi-hop relay direct mode is selected in two modes, namely, an independent relay device is utilized, and a relay function is added to each cluster terminal; the network participation direct mode refers to that when the cluster terminal establishes direct connection, the network participates, the network exits after the direct connection is established, the mode is used for UE to initiate a direct connection mode request to the network, then the network distributes wireless resources and end-to-end encryption keys to calling UE and called UE, and the direct connection function is achieved.

In the above mentioned DMO three modes, the UE information in the preset range may be obtained in any one mode, and the UE information may be embodied in a form of a list, where the UE information includes the number of UEs in the preset range.

Specifically, the UE may obtain UE information when searching for the PSDCH, and may further include a neighbor list of the UE in addition to the number of UEs, where the neighbor list of the UE includes UE identification information corresponding to the UE, and the UE identification information is used to indicate a specific UE. If the UE1 can obtain the neighbor list of the UE1 by reading the PSDCH, where there are UE6, UE7, and UE0, and the UE2 communicating with the UE1 can also obtain the neighbor list of the UE2 by reading the PSDCH, where there are UE3, UE4, UE5, and UE0, then the total number of UEs in the communication range between the UE1 and the UE2 can be calculated, and the UE0 in the overlapping portion is removed, so that 6 UEs in total are obtained for the UE6, the UE7, the UE3, the UE4, the UE5, and the UE 0.

The UE respectively has a certain distance, communication can be realized within the certain distance, and the communication effect between the UE with the closer distance is better.

It should be noted that the preset range may be a preset fixed range, or may be an effective range within which the UE can send a signal, and therefore, the preset range is not limited herein.

Secondly, in the embodiment of the present invention, a method for acquiring the number of the second UE is introduced correspondingly, the total number of UEs in the entire target network is determined by acquiring the number of UEs in a preset range, and the total number of UEs is determined as the number of the second UE. The scheme of the invention has feasibility in practical application, improves the practicability of the scheme and further improves the user experience.

Optionally, on the basis of the embodiment corresponding to fig. 1, in a second optional embodiment of the method for resource allocation provided in the embodiment of the present invention, when the size of the change of the first UE number exceeds the preset threshold, before acquiring the changed second UE number, the method may further include:

one or more preset thresholds are set according to the first UE number.

In this embodiment, when the variation size of the first UE number exceeds a preset threshold, the second UE number after variation needs to be acquired. However, one or more preset thresholds may be set before that based on the first number of UEs.

Specifically, if a preset threshold is set, only a reasonable number needs to be set according to the number of the first UEs. If multiple preset thresholds are set, multiple settings may be used. For example, a plurality of irregular threshold values, which may be irregular values such as 5, 8, 10, and 15, may be set as the threshold values, or a plurality of threshold values with gradients, which may be regular values such as 5, 10, 15, and 20, may be set as the threshold values.

It should be understood that the threshold values mentioned in the above embodiments are only an illustration, and different threshold values may be set in practical applications, and are not limited herein.

In the embodiment of the present invention, when the preset threshold is set, a specific value may be set, or multiple specific thresholds may be set, in practical applications, the change of the number of UEs may occur multiple times of increasing or decreasing changes, and multiple specific thresholds are provided to support different processing modes caused by multiple times of changing, so that the scheme has stronger operability, and meanwhile, the application range of the scheme is enlarged.

Optionally, on the basis of the embodiment corresponding to fig. 1, in a third optional embodiment of the method for resource allocation provided in the embodiment of the present invention, before determining the number of resources allocated to each UE according to the number of the first user equipment UEs, the method may further include:

In this embodiment, before allocating the number of RBs to each UE, the total number of RBs needs to be obtained first, where in general, an RB is a connection format set between the UE and an Evolved Universal Terrestrial Radio Access Network (UTRAN), and allocation of RBs is related to configuration of a physical channel, a transmission channel, and a logical channel. If there is no traffic, no RB is required. When there is traffic, the RB must be configured.

The RB is mainly determined by the frequency domain range of a single cell in scheduling, and therefore, the number of RBs is determined. The central frequency point is the middle position of the frequency domain range, and wireless transceiving or broadcasting and the like are transmitted on fixed time-frequency resources relative to the central frequency point. The UE assumes that a cell is a certain central frequency point, and then detects synchronization on corresponding time-frequency resources, which is equivalent to a constraint, and all blind detections are based on one central frequency point and bandwidth.

In the communication protocol, the maximum number of RBs is 110, there are 100 RBs in the bandwidth of 20MHz, and there are 50 RBs in the bandwidth of 10MHz, which can be calculated according to the actual situation.

Further, in the embodiments of the present invention, a method for acquiring a total number of resources is provided, where the number of resources available to each UE is adjusted according to a change in the number of UEs in a case where the total number of resources is determined. Therefore, the scheme has practicability, and when the number of resources which can be acquired by each UE is calculated, the situation of distribution errors is avoided reasonably, and the precision of the scheme is improved.

Optionally, on the basis of the third optional embodiment corresponding to fig. 1, in a fourth optional embodiment of the method for resource allocation provided in the embodiment of the present invention, determining the number of resources allocated to each UE according to the second number of UEs may include:

and averagely distributing the total number of the allocable resources to each UE according to the second number of the UEs so that each UE acquires the corresponding number of the resources.

In this embodiment, the number of RBs allocated to each UE is determined according to the second number of UEs, and the total RBs may be averagely allocated to each UE after the total number of RBs and the second number of UEs are acquired, so that each second UE acquires the corresponding number of RBs.

Specifically, the following formula may be adopted to calculate the number of resources that each UE can acquire:

configurable frequency domain RB number per UE-total number of RBs/number of UEs

If the total number of RBs is 100 and the number of UEs is 12, the configurable frequency domain RB number per UE is 8.33333, and the RB number may be rounded down, i.e., 8.

Furthermore, in the embodiment of the present invention, a specific resource number allocation manner is provided, and the number of resources that can be obtained by each UE is calculated by using the manner, so as to enhance the practicability and operability of the scheme.

For convenience of understanding, the following describes a resource allocation method in a specific application scenario in detail, specifically:

first, allocating a time-frequency RB number to each UE in the network, where specifically, if there are 100 RBs in a 20MHz bandwidth and there are 10 UEs in total, each UE may obtain 10 RBs, and when the UE needs to send information, the UE may directly send the information on the RB.

As the number of UEs in the network changes, the number of RBs statically configured per UE also changes. When the number of the UE is increased or decreased to be less than 5, the number of the RBs allocated to each UE does not need to be changed, and when the increased or decreased number of the UE is greater than or equal to 6, the number of the RBs allocated to each UE needs to be reallocated.

When it is detected that the number of UEs in the network is changed from 10 to 20, it is determined that the number of RBs per UE needs to be reallocated. The formula is adopted:

Data may be substituted and each UE may configure the number of frequency domain RBs 100/20 5

That is, at this time, each UE is allocated to 5 RBs on average.

In order to better implement the method for resource allocation provided by the embodiment of the present invention, an embodiment of the present invention further provides a device based on the method for resource allocation. The terms are the same as those in the above method for allocating resources, and details of implementation may refer to the description in the method embodiment.

Those skilled in the art will appreciate that the intercom configuration shown in fig. 7 does not constitute a limitation of an intercom, and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.

The following describes each component of the intercom specifically with reference to fig. 7:

the RF circuit 310 may be used for receiving and transmitting signals during information transmission and reception or during a call, and in particular, receives downlink information of a base station and then processes the received downlink information to the processor 380; in addition, the data for designing uplink is transmitted to the base station. In general, RF circuit 310 includes, but is not limited to, an antenna, at least one Amplifier, a transceiver, a coupler, a low noise Amplifier (Lownoise Amplifier; LNA), a duplexer, and the like. In addition, RF circuit 310 may also communicate with networks and other devices via wireless communication. The wireless communication may use any communication standard or protocol, including but not limited to Global System for Mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), e-mail, Short Message Service (SMS), etc.

The memory 320 may be used to store software programs and modules, and the processor 380 executes various functional applications and data processing of the intercom by running the software programs and modules stored in the memory 320. The storage 320 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phone book, etc.) created according to the use of the intercom, and the like. Further, the memory 320 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 330 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the intercom. Specifically, the input unit 330 may include a touch panel 331 and other input devices 332. The touch panel 331, also referred to as a touch screen, can collect touch operations of a user (e.g., operations of the user on the touch panel 331 or near the touch panel 331 using any suitable object or accessory such as a finger, a stylus, etc.) on or near the touch panel 331, and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 331 may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 380, and can receive and execute commands sent by the processor 380. In addition, the touch panel 331 may be implemented in various types, such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 330 may include other input devices 332 in addition to the touch panel 331.

The Display unit 340 may include a Display panel 341, and optionally, the Display panel 341 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-emitting diode (OLED), or the like. Further, the touch panel 331 can cover the display panel 341, and when the touch panel 331 detects a touch operation on or near the touch panel 331, the touch panel is transmitted to the processor 380 to determine the type of the touch event, and then the processor 380 provides a corresponding visual output on the display panel 341 according to the type of the touch event. Although in fig. 7, the touch panel 331 and the display panel 341 are two independent components to implement the input and output functions of the interphone, in some embodiments, the touch panel 331 and the display panel 341 may be integrated to implement the input and output functions of the interphone.

The intercom may also include at least one sensor 350, such as a light sensor, motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that may adjust the brightness of the display panel 341 according to the brightness of ambient light, and a proximity sensor that may turn off the display panel 341 and/or the backlight when the intercom moves to the ear. As one type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications (such as horizontal and vertical screen switching, related games, magnetometer attitude calibration) for recognizing the attitude of an intercom, and related functions (such as pedometer and tapping) for vibration recognition; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured in the intercom, further description is omitted here.

Audio circuitry 360, speaker 361, microphone 362 may provide an audio interface between a user and an intercom. The audio circuit 360 may transmit the electrical signal converted from the received audio data to the speaker 361, and the audio signal is converted by the speaker 361 and output; on the other hand, the microphone 362 converts the collected sound signal into an electrical signal, which is received by the audio circuit 360 and converted into audio data, and the audio data is processed by the audio data output processor 380, and then transmitted to another interphone through the RF circuit 310, or output to the memory 320 for further processing.

WiFi belongs to short-distance wireless transmission technology, and the intercom can help the user to receive and dispatch e-mail, browse the webpage and visit the streaming media etc. through WiFi module 370, and it provides wireless broadband internet access for the user.
