The new generation of communication technology involves a non-terrestrial networks (NTN) system and the Internet of Things (IoT). Terminals under NTN and IoT NTN may trigger a radio resource control (RRC) reestablishment process through a radio link failure (RLF), enabling the terminals under NTN and IoT NTN to access the network.

According to a fifth aspect of an example of the disclosure, a computer storage medium is provided for storing instructions. The instructions, when executed, implement the method described in the second aspect or any implementation in the second aspect.
It needs to be understood that the above general description and the following detailed description are merely for example and explanatory, and cannot limit the disclosure.
Accompanying drawings here, which are incorporated in and constitute a part of this specification, illustrate examples consistent with the disclosure and together with the specification, serve to explain the principles of the disclosure.
Examples will be illustrated in detail here, and instances of which are represented in accompanying drawings. When the following description refers to the accompanying drawings, the same number in the different accompanying drawings represents the same or similar elements unless otherwise indicated. The implementations described in the following examples do not represent all implementations consistent with the disclosure. On the contrary, they are merely examples of an apparatus and method consistent with some aspects of the disclosure as detailed in the appended claims.
The disclosure relates to the technical field of wireless communications, in particular to a radio link failure detection method and apparatus, and a storage medium.
The RLF may be triggered by a set timer, and the timer is configured to determine whether a channel quality can be recovered within a certain period of time, so as to reduce the number of triggering times of the RLF. In the NTN and IoT NTN systems, if a signal intensity is low due to the terminal being at an edge of a satellite cell, the probability of channel quality recovery is low. In this case, a configured timer duration needs to be relatively small. If the signal intensity is low due to the fact that a signal of the terminal in the satellite cell is blocked, the probability of channel quality recovery is high. In this case, the configured timer duration needs to be relatively large. In the related art, the timer cannot be configured with appropriate timer durations for both the low signal intensity caused by the terminal being at the edge of the satellite cell and the low signal intensity caused by the signal of the terminal in the satellite cell being blocked. If the configured timer duration is not appropriate, it will delay link recovery or increase unnecessary RLF and RRC reestablishment.
In order to overcome the problem existing in the related art, the disclosure provides a radio link failure detection method and apparatus, and a storage medium.
It may be understood that the communication system of the network device and the terminal shown in
It may be further understood that the wireless communication system in the example of the disclosure is a network providing a wireless communication function. The wireless communication system may employ different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier FDMA (SC-FDMA), and carrier sense multiple access with collision avoidance. A network may be divided into a 2G (generation) network, a 3G network, a 4G network or a future evolution network, such as a 5G network, according to capacity, speed, delay and other factors of the different networks. The 5G network may also be called a new radio (NR) network. For convenience of description, the disclosure sometimes may refer to the wireless communication network simply as the network.
Further, the network device involved in the disclosure may also be called a radio access network device. The radio access network device may be: a base station, an evolved node B (base station), a femto, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc., may further be a gNB in an NR system, or may further be a component or part of a device that constitutes a base station. In response to determining that it is a vehicle-to-everything (V2X) communication system, the network device may further be a vehicle-mounted device. It needs to be understood that a specific technology and a specific device form employed by the network device are not limited in the example of the disclosure.
Further, the terminal involved in the disclosure may also be call a terminal device, user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., and is a device that provides voice and/or data connectivity to a user. For example, the terminal may be a handheld device and a vehicle-mounted device with a wireless connection function. At present, some examples of the terminal are: a mobile phone, a pocket personal computer (PPC), a palm computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or the vehicle-mounted device, etc. In addition, in response to determining that it is the vehicle-to-everything (V2X) communication system, the terminal may further be the vehicle-mounted device. It needs to be understood that the specific technology and the specific device form employed by the terminal are not limited in the example of the disclosure.
In the new generation of communication system, such as a 5G new radio (NR) system, non-terrestrial networks (NTN), namely a 5G satellite communication network, is introduced. In the 5G satellite communication network, due to movement of asynchronous satellites, a service time of each satellite to the terminal is limited, and the terminal will perform handover and cell reselection after a period of time. The service time of the satellite to the terminal may be determined by an orbit altitude of the satellite, different cell coverage radii, and a moving speed of the terminal. The orbit altitude of an LEO satellite is generally about 600 km.
A non-geostationary earth orbiting (Non-GEO) satellite in the NTN move at a high speed relative to a fixed location on Earth, resulting in frequent and inevitable handover between a stationary terminal and a mobile terminal. Frequent cell handover can lead to an increase in signaling overhead and potentially exacerbate other mobility-related potential issues, such as service interruptions caused by signaling delay.
For a terminal moving at a constant speed and direction, a maximum time where the terminal can maintain a connection to the satellite cell is approximately to divide a cell diameter by a movement speed of UE relative to the satellite cell. For a low earth orbiting (LEO) system, a cell size is divided by a relative speed between the UE and the satellite cell. When the UE moves in the same direction as the satellite, the relative speed is a satellite speed plus an opposite value of a UE speed. When the UE moves in the same direction as the satellite, the relative speed is the satellite speed plus the UE speed, which may be described by the following equation:
Time to HO=cell size (km)/(terminal speed (km/hr)*(1 hr/3600 s)+satellite speed (km/s))
Table 1 shows a maximum time that the terminal may be connected to a cell, calculated based on the above equation in a case that the cell diameter is 50 km and 1000 km
It may be understood that each element in Table 1 exists independently, and these elements are illustratively listed in the same table, but it does not mean that all elements in the table need exist simultaneously as shown in the table. A value of each element is independent of any other element values in Table 1. Thus, those skilled in the art can understand that the value of each element in Table 1 is an independent example.
An IoT NTN system is involved in the new generation of communication technology. An IoT terminal under IoT NTN includes a narrow band Internet of Things (NB-IoT) terminal and an LTE enhanced MTO (eMTC) terminal. The eMTC terminal supports cell handover, while the NB-IoT terminal does not support cell handover. Instead, the NB-IoT terminal triggers an RRC reestablishment process through an RLF to achieve the conversion of the IoT NTN terminal access to the cell. At present, research on the IoT NTN is based on the fact that an IoT device has a positioning function.
In the related art, the process of detecting the RLF is as follows:
In the NB-IoT, it starts after receiving N310 consecutive out-of-sync indications and stops after receiving N311 consecutive in-sync. When T310 is at expiry, an RRC connection re-establishment procedure is triggered or the terminal switches to RRC-IDLE, as shown in Table 2.
It may be understood that each element in Table 2 exists independently, and these elements are illustratively listed in the same table, but it does not mean that all elements in the table need exist simultaneously as shown in the table. A value of each element is independent of any other element values in Table 1. Thus, those skilled in the art can understand that the value of each element in Table 2 is an independent example.
It may be understood that each element in Table 3 exists independently, and these elements are illustratively listed in the same table, but it does not mean that all elements in the table need to exist simultaneously as shown in the table. A value of each element is independent of any other element values in Table 3. Thus, those skilled in the art can understand that the value of each element in Table 3 is an independent example.
For the NB-IoT device, a value range of T310 is defined to include: 0 ms, 200 ms, 500 ms, 1000 ms, 2000 ms, 4000 ms, and 8000 ms. As shown in the above parameters, in the NB-IoT, it is determined that the RLF can reach up to 8 s based on T310 timeout in a current mechanism, but a maximum connection duration for the LEO cell with a diameter of 50 km is about 6 s.
The larger the T310 setting, the longer it takes for the UE to detect RL downlink out-of-step. During this time, relevant resources cannot be released timely, nor can recovery operations be initiated or a new resource establishment request be responded to, increasing the possibility of interruption. If T310 is set too small, the RLF will be triggered frequently.
For NB-IoT UE in the NTN system, RLF detection may be triggered by the set timer, and the timer is configured to wait for channel quality recovery. If it is located at an edge of the satellite cell and is about to lose coverage of the satellite cell, it needs to wait for timeout of the timer T310 to determine the radio link failure. However, in these scenarios, channel quality is difficult to recover. If T310 is set too large at this time, waiting for timeout of the timer will delay link recovery, increase interruptions, and also consume electricity during the RLF detection process, causing unnecessary power consumption of the IoT device. However, for UE within a coverage range of the NTN, if a signal intensity of the satellite cell is blocked, it needs to configure a suitable T310, so that the UE can have time to wait for channel quality recovery, thus avoiding unnecessary RLF. In the related art, the timer duration configured for the timer T310 cannot simultaneously meet the timer durations for RLF detection when the terminal is in different locations.
The disclosure provides an RLF triggering method. The RLF triggering method is applicable to a detection method of an RLF for an IoT NTN system, and certainly applicable to detection of other RLFs.
The RLF detection method provided by the disclosure introduces a new timer duration, selects different timer durations based on a location of a terminal relative to a satellite, and starts a timer according to its corresponding timer duration. For example, when the terminal is located at an edge of a satellite cell, a timer duration corresponding to a situation that the terminal is located at the edge of the satellite cell is selected, and the timer is started based on the timer duration to detect the RLF. The RLF is detected in a case of timeout of the timer. When the terminal is away from the edge of the cell, a timer duration corresponding to a situation that the terminal is away from the edge of the cell is selected, and the timer may be started according to the timer duration to detect the RLF.
The RLF detection method provided by the disclosure may further introduce a new timer, and the different timers correspond to different locations of the terminal relative to the satellite. The corresponding timer is started according to the location of the terminal relative to the satellite. For example, when the terminal is located at the edge of the satellite cell, the timer corresponding to the situation that the terminal is located at the edge of the satellite cell is selected, and the timer is started to detect the RLF. The RLF is detected in a case of timeout of the timer. When the terminal is away from the edge of the cell, a timer corresponding to the situation that the terminal is away from the edge of the cell is selected, and the timer is started to detect the RLF. The RLF is detected in a case of timeout of the timer. The timer may further be stopped on this basis.
The RLF detection method provided by the disclosure may further introduce a scaling factor, and uses the scaling factor to adjust the timer duration. When the location of the terminal relative to the satellite meets a selection condition, the scaling factor may be used to adjust the timer duration, and the RLF may be detected based on the adjusted timer duration.
Based on the multiple RLF detection methods provided by the disclosure, the UE located at the edge of the satellite cell can trigger the RLF at an appropriate time, RRC reestablishment can be reduced, or a network transmission environment can be ensured to be recovered in time, so that the terminal can quickly recover the connection with a network or enter an idle state.
The technical solution provided by the examples of the disclosure may include the following beneficial effects: through the disclosure, the start of first timer or the first timer duration is determined according to the location information of the terminal and/or the configuration information of the network device, for detecting the RLF, thus an appropriate time can be determined based on the location of the terminal, and the RLF can be detected within the time corresponding to the location of the terminal, which can reduce RRC reestablishment, or ensure that a network transmission environment can be recovered in time, so that the terminal can quickly recover the connection with the network or enter an idle state.
In the example of the disclosure, the terminal starts the timer for RLF detection based on its own location information and network configuration information. In the following implementations, the implementation that the terminal starts the timer for RLF detection based on its own location information and the network configuration information is illustrated below first.
In step S11, configuration information related to RLF detection is determined, and location information of the terminal is determined.
In step S12, a first timer is started based on the configuration information and/or the location information of the terminal.
The first timer is used for RLF detection.
In the example of the disclosure, the terminal determines the configuration information related to the RLF detection and configured by a network device, or receives signaling sent by the network device, and determines the configuration information related to the RLF detection based on the signaling. The signaling may be a broadcast message, proprietary signaling or the like.
The terminal acquires the location information of the terminal according to its own global navigation satellite system (GNSS) capability. The location information of the terminal may further be determined according to the proprietary signaling of a network.
Further, the terminal determines to start the first timer according to the obtained configuration information related to the RLF detection and/or the location information of the terminal.
Through the RLF detection method provided by the example of the disclosure, the first timer for RLF detection is started based on a starting condition according to the location of the terminal, so that the corresponding first timer for RLF detection may be determined based on different locations of the terminal relative to the satellite, which can reduce RRC reestablishment, or ensure that a network transmission environment is recovered in time, so that the terminal can quickly recover the connection with the network or enter an idle state.
The starting condition included in the configuration information may be indicated by the network device or specified through a protocol, as mentioned above, which is not specifically limited here. It may be understood that if the starting condition is indicated by the network device to the terminal, the network device may dynamically indicate or reconfigure the starting condition according to the actual situation.

The first timer is started in a case that the relative location relationship between the terminal and the cell meets the starting condition included in the configuration information.

Or, the first timer is started in a case that the magnitude of the elevation angle between the terminal and the satellite is continuously greater than the elevation angle threshold within the triggering time.
As mentioned above, the terminal may start the first timer based on the starting condition included in the configuration information, as well as the relative location relationship between the terminal and the satellite.

The corrected distance is compared with the first threshold, and the first timer is determined to be started based on comparison results.
