The terminology used in the description of the embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application, as will be described in detail with reference to the accompanying drawings.
In order to facilitate the technical personnel to understand the technical scheme of the embodiment of the application, the technical terms related to the embodiment of the application are explained below.
1. The third generation partnership project (Third Generation Partnership Project,3 GPP) protocol is a series of related standard documents formulated to implement the interoperability of 3GPP networks and wireless local area networks (Wireless Local Area Network, WLAN).
2. The long term evolution (Long Term Evolution, LTE) system is used for the long term evolution of the universal mobile telecommunication system (Universal Mobile Telecommunications System, UMTS) technical standard established by the 3GPP organization, introduces key technologies such as orthogonal frequency division multiplexing and multiple input multiple output, and the like, and significantly increases the spectrum efficiency and the data transmission rate.
3. A radio resource control (Radio Resource Control, RRC) for handling layer three information of the control plane between the user equipment and the base station. The RRC is responsible for network-side connection of the user equipment to perform establishment, re-establishment, maintenance and release of radio resources. Mobility management of RRC connections is responsible for evaluation, decision and execution of tasks related to the mobility of established connections, such as migration or migration preparation to the global system for mobile communications (Global System for Mobile communications, GSM) or other wireless networks, cell reselection, cell update, and measurement of user equipments.
The application scenario of the embodiments of the present application will be first described with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a long term evolution system. The LTE system includes a core network, a network side, and User Equipment (UE). The core network may be EPC of fourth generation mobile communication network (4th generation mobile networks,4G), or 5GC of fifth generation mobile communication network (5th generation mobile networks,5G), or a future network. The network side may be a 4G base station, a 5G base station or a base station in a future network. The embodiment of the present application does not limit the types of the user equipment, the network side and the core network, and the specific types of the user equipment, the network side and the core network in the present application are only used for exemplary illustration. Taking a 4G core network EPC and a network side as eNB base stations as examples, the base stations interact with the core network and user equipment to realize the coverage of mobile communication services. In the forward signal transmission process, signals such as control signaling, voice call or data service information of a core network are sent to a base station through a transmission network, the signals are processed in the base station through baseband and radio frequency, then sent to an antenna through a radio frequency feeder line to be transmitted, and user equipment receives radio waves transmitted by the antenna through a wireless channel and then demodulates self signals. The reverse signal transmission process is opposite to the forward signal transmission process.
In the process, the base station needs to perform mobility management on the user equipment, and the base station completes real-time reporting and updating of the position information of the user equipment through close matching of the network element and the user equipment, and completes switching processing in the call process so as to ensure continuity of communication service and further promote user experience.
In a specific implementation, the ue needs to report its own location to the base station, provide ue identity and maintain physical channels. When the user equipment and the base station establish connection through RRC, the user equipment is in a connected state. If the user equipment moves in the connected state, the mobile network can provide a smooth physical channel for the user equipment through switching, so that continuous user experience is ensured. The switching is a process of changing the serving cell when the user equipment is in a connected state, and comprises same-frequency switching, different-frequency switching and different-system switching.
Fig. 2 is a schematic diagram of a handover procedure. As shown in fig. 2, the handover includes three phases of handover measurement, handover decision, and handover execution. In the switching measurement stage, after the user equipment establishes connection with the base station, the base station issues measurement configuration information through RRC according to the starting condition of the connection state movement characteristic, the user equipment performs switching measurement according to the issued measurement configuration information, and event triggering reporting is performed to report a measurement result to the base station. In the switching judgment stage, the base station judges according to the measurement result reported by the user equipment and decides whether to trigger switching. And in the switching execution stage, the base station controls the user equipment to switch to the target cell according to the decision result to finish switching.
In a specific implementation process of the handover measurement phase, measurement configuration information issued by the base station includes measurement objects, report configuration and other parameters. The measurement object is an object for the user equipment to execute measurement and comprises a target system and a measurement frequency point. The reporting configuration comprises relevant parameters of the respective event, e.g. the reporting configuration comprises event A1, event A1 indicating that the serving cell quality is above a certain threshold, the user equipment reporting the measurement result when the event triggering condition is fulfilled. The measurement result reported by the user equipment is not the measurement result directly obtained by the user equipment, before the measurement result is reported, the user equipment also needs to further process the direct measurement result through an LTE measurement model, and in the further process, the use of other parameters, such as Layer3 (L3) filter coefficients, is also involved.
Fig. 3 is a schematic diagram of a measurement model of a long term evolution system of a user equipment. As shown in fig. 3, the ue obtains a direct measurement result a of the physical Layer through the LTE measurement model, performs Layer1 (Layer 1, L1) filtering on a in the physical Layer to obtain a measurement result B of L1 filtering, and then sends the measurement result B of L1 filtering to the RRC Layer to perform L3 filtering to obtain a measurement result C of L3 filtering, where the ue uses the measurement result C of L3 filtering and other measurement results C' (such as signal-to-interference-and-noise ratio SINR, and channel quality indicator CQI, which are measured in the same manner as C, but do not need to pass through L3 filtering) together to evaluate the reporting condition, so as to obtain a measurement report message D sent to the base station by the ue. It should be noted that, when the ue performs L3 filtering in the RRC layer, the RRC configuration parameter E obtained from the base station provides the L3 filtering coefficient to the RRC layer, and when the ue uses the measured value C of the L3 filtering together with other measured values C' to evaluate the reporting condition, the RRC configuration parameter F obtained from the base station provides the reporting configuration of the measurement.
The following formula is used to process the direct measurement results before the user equipment reports the measurement results.
F n ＝(1-a)×F n-1 +a×M n ；
Wherein M is n Is the n 1 th filtered measurement; f (F) n-1 Is the measurement result after the n-1 th L3 filter; f (F) n Reporting the measurement result n;a is a weight coefficient of the current measurement, k is a corresponding L3 filter coefficient, and when k=0, i.e. a=1, L3 filtering is not performed.
The reported measurement result of the ue includes a reference signal received power (Reference Signal Received Power, RSRP) and a reference signal received quality (Reference Signal Received Quality, RSRQ) for evaluating the quality of a serving cell of the LTE system. The RSRQ also considers interference factors on the basis of the RSRP, and the RSRQ and the RSRP can be respectively configured through corresponding parameters.
However, in some scenarios (e.g., high-speed scenarios), the RSRP and/or RSRQ measured by the user equipment changes faster because the user equipment movement speed changes too fast. At this time, if the weight coefficient of the current measurement is smaller, the signal strength of the current user equipment cannot be truly reflected, so that the switching speed of the user equipment is affected.
The method aims to solve the problems that the measurement result reported to the network side is inaccurate and the switching speed of the user equipment is influenced due to the fact that the moving speed of the user equipment in part of scenes is too high. The embodiment of the application provides a filter coefficient adjusting method.
The filter coefficient adjustment method provided by the embodiment of the invention can be applied to User Equipment (UE). The user equipment comprises, but is not limited to, a mobile phone, a tablet personal computer, a workstation device, a large screen device (such as a smart screen, a smart television and the like), a wearable device (such as a smart bracelet, a smart watch) and a palm game machine, a household game machine, a virtual reality device, an augmented reality device, a mixed reality device and the like, a vehicle-mounted intelligent terminal and the like.

Fig. 5 is an exemplary flowchart of a method for adjusting a filter coefficient according to an embodiment of the present application.
As shown in fig. 5, the filter coefficient adjustment method specifically includes the following steps S101 to S104:
step S101, determining that user equipment is in a target use scene based on a first identifier sent by a network side;
the network side may be a plurality of base stations, each base station may provide communication coverage for one or more cells (i.e. a special geographical area), and the radius of the cells may range from several meters to several kilometers. The user equipment may communicate at any location of the communication coverage. In the interaction process of the user equipment and the base station, the user equipment can communicate with the base station corresponding to the cell in the corresponding cell so as to acquire the system message issued by the base station. The system message issued by the base station may include a serving cell identifier, a base station location, a base station coverage area, and a network type. The serving cell identity may embody a current usage scenario of the user equipment.
It should be noted that the network side in the present application may be applied to different communication systems. The specific equipment of the base station is different corresponding to different communication systems, and may specifically be a base station controller (Base Station Controller, BSC), a radio network controller (Radio Network Controller, RNC), an evolved base station (eNB) or a base station (NodeB).
The usage scenario of the user equipment may include multiple usage scenarios such as an indoor usage scenario, an outdoor usage scenario, an airplane usage scenario, a train usage scenario, and a high-speed railway usage scenario, in a living scenario where the user equipment such as the indoor usage scenario has a slow moving speed, a reporting measurement result of RSRP and/or RSRQ obtained by using a formula specified by a 3GPP protocol can reflect a current signal strength relatively truly, and in a special scenario where the user equipment such as the high-speed railway usage scenario has a fast moving speed, a reporting measurement result of RSRP and/or RSRQ obtained by using a formula specified by the 3GPP protocol cannot truly reflect a signal strength of a current user equipment, so that the special scenario is taken as a target usage scenario, and when the user equipment is switched from the living scenario to the target usage scenario, the user equipment executes the filter coefficient adjustment method shown in the present application.
In some embodiments, the user equipment may acquire a system message sent by the network side, determine whether the system message includes a first identifier, and by way of example, the first identifier may be a high-speed rail cell identifier, and when the system message includes the first identifier, further determine whether an identifier value of the first identifier is a first identifier value; if the identification value of the first identification is the first identification value, the user equipment can be determined to be in the target use scene, namely the high-speed rail use scene.
In a specific implementation, the system message includes parameters for representing the usage scenario. The embodiment of the application takes the parameter for identifying the usage scenario as a first identification. The parameter may include a True field or a False field, and the True field and the False field are used as identification values in the present application. In this embodiment of the present application, the True field is used as the first identification value. If the identification value of the first identification is True field, it can be determined that the user equipment is in the target use scene and can perform its function, and if the identification value of the first identification is Fales identification value, it can be determined that the user equipment is not in the target use scene or is in the target scene but cannot perform its function.
For example, the parameters used to represent the usage scenario in the system message are as follows:
it should be noted that, the first identifier in the application includes, but is not limited to, a high-speed railway cell identifier, and the target usage scenario includes, but is not limited to, a high-speed railway usage scenario, and the embodiment of the application may be applied to other scenarios with too high a moving speed.
In some embodiments, the ue may acquire an RRC message sent by the network side, and determine whether the ue is in a high-speed mobile state. In a specific implementation, the ue may indicate that the ue is in a high-speed mobile state through a first indicator bit in the RRC message. The first indicator bit is one of the bits in the RRC message, and may be pre-agreed that the first indicator bit is 0 and represents the high-speed moving state, or may be pre-agreed that the first indicator bit is 1 and represents the high-speed moving state. The user device may determine the target usage scenario through the current state.
In some embodiments, when the user equipment is in an idle state, the user equipment may determine whether itself is in a high-speed moving state by reading a system message; when the user equipment is in a connected state, the user equipment can determine whether the user equipment is in a high-speed moving state or not by reading a system message or by reading network special signaling. In a specific implementation, the user equipment may indicate that the user equipment is in a high-speed moving state through a second indicator bit in the system message. The second indicator bit is one of the system messages, and can be preset to be 0 to represent the high-speed moving state, or preset to be 1 to represent the high-speed moving state. The user device may determine the target usage scenario through the current state.
It should be noted that, the present application includes, but is not limited to, determining the target usage scenario of the ue in the above manner, and the ue may further obtain, from the network side, other notification information capable of confirming that the ue is in a high-speed moving state, so as to determine the target usage scenario through the current state.
Step S102, obtaining the moving speed of user equipment and obtaining a first measurement period configured by a network side;
In some embodiments, the user device may obtain the movement speed through a motion sensor of the user device. The motion sensor may be one or more of an acceleration sensor and a gyro sensor. It should be noted that, because the moving speed of the ue changes faster in the target usage scenario, the manner of acquiring the moving speed of the ue from the network side has the problem of poor accuracy caused by delay, and the manner of acquiring the moving speed by the motion sensor of the ue can dynamically reflect the moving speed of the current ue, and has higher accuracy.
In some embodiments, the ue may acquire an RRC message sent by the network side, and acquire a discontinuous reception (Discontinuous Reception, DRX) period and a first measurement reference signal period from the RRC message. For example, the first measurement reference signal period may be a synchronization signal SSB (Synchronization Signal block, SSB) period; the user equipment may determine the first measurement period according to the DRX cycle and the SSB cycle.
The DRX cycle may periodically wake up the user equipment to listen for paging messages while the user equipment is in an idle state. The SSB period is used to support periodic transmission of the synchronization signal. The first measurement period determined by the user equipment according to the DRX cycle and the SSB cycle is substantially an L1 measurement period, and the value of the L1 measurement period may be generally set to 200 ms, 400 ms, 600 ms, etc.
In a specific implementation, the RRC message includes a parameter that indicates a DRX cycle mixed SSB cycle. The embodiment of the application can determine the first measurement period according to the corresponding parameter in the RRC message.
For example, as in 3GPP technical document TS38.331, parameters in RRC message for indicating DRX cycle are as follows:
/>
for example, as in 3GPP technical document TS38.331, parameters in RRC message for representing SSB periods are as follows:
/>
here, it should be noted that the first measurement period is issued by the network side, and the ue can only acquire the first measurement period and cannot change the first measurement period.
It should be noted that the manner of determining the first measurement period is not limited in this application, and the first measurement period may be determined according to one or more first measurement reference signal periods. The specific determination mode is set according to actual conditions.
Step S103, determining a first weight corresponding to a first measurement result and a second weight corresponding to a second measurement result according to the moving speed and the first measurement period, wherein the first measurement result is a layer 1 filtering measurement result obtained by the user equipment in the N first measurement period, and the second measurement result is a layer 3 filtering measurement result obtained by the user equipment in the N-1 first measurement period, wherein the sum of the first weight and the second weight is 1, N is a positive integer, and N is more than 1.
The ue may obtain direct measurement results, that is, actual measurement values of RSRP and RSRQ, and process the direct measurement results through the LTE measurement model. In the LTE measurement model, a user equipment provides an L1 filtering function through a Physical (PHY) layer, which is associated with error detection on a transmission channel, forward error correction (Forward error correction, FEC) encoding/decoding of the transmission channel, interleaving, rate matching, mapping to a Physical channel, modulation/demodulation of the Physical channel, multiple-input and Multiple-output (MIMO) antenna processing, and the like. The user equipment filters the direct measurement result through the physical layer, and can obtain an L1 filtering measurement result.
It should be noted that the LTE measurement model described in the embodiments of the present application is only used for exemplary illustration, and in 4G, 5G or future networks, the filtering manner in the present application may also be implemented according to other measurement models.
The user equipment provides an L3 filtering function through the RRC layer, which is associated with push of system information, connection control and measurement configuration. The user equipment filters the L1 filtering measurement result through L3 filtering to obtain an L3 filtering measurement result.
Since the 3GPP protocol specifies that the ue needs to process the direct measurement result using the following formula before reporting the measurement result, namely:
F n ＝(1-a)×F n-1 +a×M n ；
wherein M is n Is the measurement result after the Nth L1 filter; f (F) n-1 Is the measurement result after the N-1 th L3 filtering; f (F) n Reporting the measurement result by the Nth step;a is a weight coefficient of the current measurement, k is a corresponding L3 filter coefficient, and when k=0, i.e. a=1, L3 filtering is not performed.
In the above formula, k is an L3 filter coefficient issued by the network side, and is typically a parameter fc4 or fc6 in the filter coefficient (Filter coefficient) in the RRC message, thus M n The duty cycle in reporting the measurement is typically 0.5 or 0.35.
The smaller the value of a, the larger the filtering effect, the stronger the smoothing effect on the signal and the stronger the fast fading resistance, but the weaker the tracking ability on the signal change and the insensitivity to the fast-changing signal reaction; the larger the value of a, the smaller the filtering effect, the weaker the smoothing effect on the signal and the weaker the fast fading resistance, but the stronger the tracking ability on the signal change and the sensitivity to the fast changing signal response. In the target use scene of the application, the RSRP and/or RSRQ change speed is high, and the smaller a value cannot truly reflect the current signal strength, so that the application dynamically adjusts the first weight corresponding to the first measurement result and the second weight corresponding to the second measurement result according to the moving speed and the measurement period.
In the embodiment of the present application, the following formula is needed to process the direct measurement result, namely:
F n ＝(1-b)×F n-1 +b×M n ；
wherein M is n Is the first measurement result after the N (N is a positive integer and N is more than 1) L1 is filtered; f (F) n-1 Is the second measurement result after the N-1 th L3 filter; f (F) n Is the nth third measurement result; b is a first weight corresponding to the first measurement result, and 1-b is a second weight corresponding to the second measurement result.
In some embodiments, step S103 may be performed by performing the following steps S1031-S1032 to obtain the first weight and the second weight.
Step S1031, obtaining a first speed index corresponding to the moving speed and a first time index corresponding to the first measuring period; wherein, the speed indexes corresponding to different speed intervals are different, and the time indexes corresponding to different period intervals are different. Wherein, the user equipment sets at least one speed interval and at least one period interval; each speed interval corresponds to one speed index, wherein the larger the corresponding speed of the speed interval is, the larger the corresponding speed index is; each period interval corresponds to a time index, and the larger the period corresponding to different period intervals is, the larger the corresponding time index is.
In specific implementation, a speed interval is set every first threshold value, and a period interval is set every second threshold value; wherein the M < th >, is 1 The corresponding speed index of each speed interval is M 1 -1，M 1 Is a positive integer and M 1 1 or more, P 1 The corresponding time index of each period interval is P 1 ，P 1 Is a positive integer and P 1 ≥1。
For example, a first speed interval is set with a first threshold of 120 km/h, and the first speed interval may be set to have a moving speed of less than or equal to 120 km/h, where the first speed index corresponding to the first speed interval is 0; the second speed interval may be set such that the moving speed is greater than 120 km/h and less than or equal to 240 km/h, at which time the first speed index corresponding to the second speed interval is 1; the third speed interval may be set such that the moving speed is greater than 240 km/h and less than or equal to 360 km/h, at which time the first speed index corresponding to the third speed interval is 2; the fourth speed interval may be set such that the moving speed is greater than 360 km/h and less than or equal to 480 km/h, at which time the first speed index corresponding to the fourth speed interval is 3; the fifth speed interval may be set such that the moving speed is greater than 480 km/h and less than or equal to 600 km/h, at which time the first speed index corresponding to the fifth speed interval is 4.
For example, a period interval is set with the second threshold being 200 ms, and the first period interval may be set to be equal to 200 ms, where the first time index corresponding to the first period interval is 1; the second period interval may be set such that the first measurement period is equal to 400 ms, and at this time, the first time index corresponding to the second period interval is 2; the third period interval may be set such that the first measurement period is equal to 600 milliseconds, at which time the first time index corresponding to the third period interval is 3.
Here, it should be noted that, in the embodiment of the present application, the number of the speed intervals and the period intervals is not limited, and the values of the first threshold value and the second threshold value are not limited.
The user equipment determines a target speed interval in which the moving speed is located, determines a speed index corresponding to the target speed interval as a first speed index, determines a target period interval corresponding to a first measurement period, and determines a time index corresponding to the target period interval as a first time index.
For example, when the movement speed obtained by the user equipment is 250 km/h, the user equipment may determine that the target speed interval in which the movement speed is located is a second speed interval, where the first speed index is 1; when the first measurement period acquired by the user equipment is 200 ms, the user equipment may determine that the target period interval in which the first measurement period is located is the first period interval, and at this time, the first time index is 1.
In step S1032, the first weight and the second weight are determined according to the product of the first speed index and the first time index.
In a specific implementation, the user equipment performs steps S1032a-S1032c as shown in fig. 6.
Step S1032a, according to the product Q of the first speed index and the first time index 1 Acquiring a first value ofQ of (2) 1 To the power.

By way of example, when the second value is 16, the L3 filter coefficient is 4,at this time, the first weight is
Step S1034c, determining a second weight according to the first weight.
For example, when the first weight is 0.841, the second weight is 1-0.841=0.159.

For example, a period interval is set with the sixth threshold being 200 ms, and the first period interval may be set to be equal to 200 ms, where the first time index corresponding to the first period interval is 1; the second period interval can be set to be equal to 400 ms, and the first time index corresponding to the second period interval isThe third period interval may be set such that the first measurement period is equal to 600 ms, in which case the third period interval corresponds to a first time index +.>
Here, in the embodiment of the present application, the number of the speed interval and the period interval is not limited, and the values of the third threshold value and the fourth threshold value are not limited.
The user equipment determines a target speed interval in which the moving speed is located, determines a speed index corresponding to the target speed interval as a first speed index, determines a target period interval corresponding to a first measurement period, and determines a time index corresponding to the target period interval as a first time index.
For example, when the movement speed obtained by the user equipment is 250 km/h, the user equipment may determine that the speed interval in which the movement speed is located is the second speed interval, where the first speed index isWhen the first measurement period acquired by the user equipment is 200 ms, the user equipment may determine that the period interval in which the first measurement period is located is a first time interval, and at this time, the first time index is 1.

Step S1036b, according to the product Q of the first speed index and the first time index 6 Acquiring a first weight value with the third value, wherein the first weight value is Q of the third value 6 To the power.
Illustratively, when the first speed index isThe first time index is 1, the third value is +.>In the time-course of which the first and second contact surfaces,at this time, the first weight is +.>
Step S1036c, determining the second weight according to the first weight.
For example, when the first weight is 0.707, the second weight is 1-0.707=0.293.
Step S104, the first measurement result and the second measurement result are weighted and summed according to the first weight and the second weight to obtain a third measurement result, wherein the third measurement result is a measurement result for reporting to the network side.
In a specific implementation, the third measurement result is obtained by the following formula:
F n ＝(1-b)×F n-1 +b×M n ；
wherein M is n Is the first measurement result after the Nth L1 filter; f (F) n-1 Is the second measurement result after the N-1 th L3 filter; f (F) n Is the nth third measurement result; b is a first weight corresponding to the first measurement result, 1-b is a second weight corresponding to the second measurement result, N is a positive integer and N is more than 1.
For example, taking the first weight value of 0.707 and the second weight value of 0.293 as an example, if the first measurement result after the L1 filtering in the second L1 measurement period is-100 dbm and the second measurement result after the L3 filtering in the first L1 measurement period is-100 dbm, the third measurement result F 2 ＝0.293×-100+0.707×-100＝-100dbm。
If the first measurement result after L1 filtering in the third L1 measurement period is-120 dbm and the second measurement result after L3 filtering in the second L1 measurement period is-100 dbm, the third measurement result F 2 ＝0.293×-100+0.707×-120＝-114dbm。
If the first measurement result after L1 filtering in the fourth L1 measurement period is-130 dbm and the second measurement result after L3 filtering in the third L1 measurement period is-110 dbm, the third measurement result F 3 ＝0.293×-110+0.707×-130＝-125dbm。
For example, taking the first weight value of 0.841 and the second weight value of 0.159 as examples, if the first measurement result after L1 filtering in the second L1 measurement period is-100 dbm and the second measurement result after L3 filtering in the first L1 measurement period is-100 dbm, the third measurement result F 2 ＝0.159×-100+0.841×-100＝-100dbm。
If the first measurement result after L1 filtering in the third L1 measurement period is-120 dbm and the second measurement result after L3 filtering in the second L1 measurement period is-100 dbm, the third measurement result F 2 ＝0.159×-100+0.841×-120＝-116dbm。
If the first measurement result after L1 filtering in the fourth L1 measurement period is-130 dbm and the second measurement result after L3 filtering in the third L1 measurement period is-110 dbm, the third measurement result F 3 ＝0.159×-110+0.841×-130＝-128dbm。
The reported measurement results obtained in the above 3 measurement periods are-100 dbm, -110dbm, and-120 dbm, respectively, by the formula specified in the 3GPP protocol.
