In an embodiment of the present invention, as shown in fig. 1, a method for implementing cell reselection includes:
s100, after a cell reselection function is triggered, determining a current use scene of user equipment;
in particular, the user device includes, but is not limited to, a mobile phone, a tablet, a notebook, and the like. The use scenes of the user equipment include, but are not limited to, ship use scenes, high-speed rail use scenes, airplane use scenes, city use scenes and remote area use scenes. After the user equipment is powered on, if the cell reselection function is triggered, the user equipment can automatically detect and judge the current use scene of the user equipment, and of course, the current use scene of the user equipment can also be manually input.
S200, selecting a corresponding mobile communication network according to the current use scene and the reselection priority table;
specifically, after determining the current usage scenario of the ue at the current time, the ue may select a mobile communication network to which the ue is to be connected according to a reselection priority table preset and stored in the ue. The mobile communication network herein refers to a wireless network required for LTE cell reselection, and the network type of the mobile communication network includes a terrestrial network or a non-terrestrial network.
S300 selects a target cell meeting the cell selection criterion according to the selected mobile communication network, and performs camping to complete cell reselection.
Specifically, after the ue selects to connect to the mobile communication network, the ue performs cell selection according to a cell selection criterion, which is generally an S criterion. Wherein, the S criterion refers to Srxlev >0, and it needs to be known that:
Srxlev＝Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)-Pcompensation
wherein, Qrxlevmeas is the Reference Signal Received Power (RSRP) of the candidate cell; qrxlevmin is the minimum reference signal received power in the cell, and is obtained from the broadcast information; qrxlevminooffset is an offset value to the minimum access level; pcompensation ═ MAX (PEMAX-PUMAX, 0)), i.e., the maximum value between the difference of the maximum usable uplink transmit power PEMAX of the ue minus the maximum rf output power PUMAX of the ue and 0.
In short, the ue screens out a plurality of neighboring cells meeting the S criterion, and selects one neighboring cell as a target cell to camp on to complete cell reselection from the plurality of neighboring cells meeting the S criterion. Through the embodiment, a proper mobile communication network can be selected according to different use scenes for cell reselection, so that the user equipment can select a proper cell to initiate reconstruction, the continuity of data services of the user equipment is ensured, the performance of the mobile terminal is effectively improved, the processing process is simple and rapid, the working performance is stable and reliable, and the application range is wide.
In an embodiment of the present invention, as shown in fig. 2, a method for implementing cell reselection includes:
s110, detecting a selective receiving level value of a service cell where the user equipment is located at the current moment;
s120, when the selective reception level value is less than or equal to the preset threshold value, determining to trigger a cell reselection function;
specifically, when Srxlev (i.e., the selected reception level value) of the serving cell where the user equipment is located is less than or equal to the RSRP threshold (i.e., the preset threshold), the TN or NTN neighbor cell measurement is started, so that power consumption loss of the user equipment can be greatly reduced, power consumption and CPU consumption of frequent cell reselection are reduced, and an energy-saving effect is achieved.
S130, after the cell reselection function is triggered, determining the current use scene of the user equipment according to the state data acquired by the sensor and/or the input information;
in particular, the sensors include, but are not limited to, vision sensors (e.g., cameras), motion sensors (e.g., acceleration sensors, gyroscopes, magnetic field sensors, displacement sensors, etc.), and GPS sensors. The state data includes, but is not limited to, environmental image data, latitude and longitude data, displacement data, and velocity data.
Assuming that the speed per hour of a high-speed rail is 300 km/h, the speed per hour of a ship is between 28 km/h and 50 km/h, and the speed per hour of an airplane is between 600 km/h and 800 km/h. The user equipment is internally provided with the sensor, for example, the user equipment acquires surrounding environment image data according to the visual sensor, acquires speed data of the user equipment according to the motion sensor, and can judge that the current use scene of the user equipment at the current moment is possibly a high-speed rail use scene according to the environment image data and the speed data.
Of course, after the user equipment triggers the cell reselection function, an input box is displayed on a display interface of the user equipment, and the user manually inputs and selects a current usage scenario of the user equipment. Certainly, after the user equipment triggers the cell reselection function, selection controls are displayed on a display interface of the user equipment, each selection control corresponds to a usage scenario, and the user equipment acquires touch information (for example, click operation) manually input by a user to select a current usage scenario of the user equipment. Of course, after the user equipment triggers the cell reselection function, if the user equipment is integrated with a microphone, the microphone may also collect a voice signal of the user and recognize the voice signal to obtain a current usage scenario of the user equipment.
Of course, since it is determined that there may be multiple candidate usage scenarios according to the status data, after the status data is acquired by the sensor, the multiple candidate usage scenarios determined by the processor of the output user equipment according to the status data may be displayed on the display interface, and then the current usage scenario of the final user equipment may be determined by combining the input information.
S210, searching a reselection priority table, and screening out a mobile communication network matched with the current use scene; the mobile communication network comprises a ground network or a non-ground network; the reselection priority table comprises each use scene and the corresponding mobile communication network with priority access;
specifically, the reselection priority table includes each usage scenario and the mobile communication network that is accessed preferentially, and generally speaking, as shown in fig. 3, the usage scenarios include a ship usage scenario, a high-speed rail usage scenario, an airplane usage scenario, a city usage scenario, and a remote area usage scenario. First, a reselection priority of the usage scenario and the mobile communication network is set. For example, in areas where a terrestrial network cannot cover or serve, such as: in remote areas, on board an aircraft or ship, the reselection priority of the mobile communication network is NTN network > TN network. Also for example, in areas where a terrestrial network can cover or serve, such as: the reselection priority of the mobile communication network at high-speed rail or city is NTN network > TN network.
Wherein, NTN is the abbreviation of Non-Terrestrial Network, namely Non-ground Network. The TN is a ground Network for short, and the ground Network includes 2G, 3G, 4G, and 5G networks. In summary, the user equipment selects a mobile communication network matching the current usage scenario according to the reselection priority table. For example, when the current usage scenario of the ue is a city usage scenario, the ue preferentially selects to access the terrestrial network.
S220, selecting a final mobile communication network according to a communication protocol supported by the user equipment and the signal coverage range of the mobile communication network;
specifically, the ue may support different communication protocols according to different types and models of chips therein, or the ue may not successfully interact with the base station due to the signal coverage of the base station signal, so the ue needs to select a mobile communication network that can be successfully connected according to the supported communication protocol and the signal coverage of the mobile communication network.
Illustratively, when the current usage scenario of the user equipment is a city usage scenario, the access to the terrestrial network is preferentially selected. Since the terrestrial networks include 2G, 3G, 4G, and 5G networks, the user equipment needs to access the terrestrial network according to the mobile communication technology supported by the SIM card inserted by the user equipment or the version of the user equipment itself and the signal coverage of the base station signal, although the user equipment is in a city use scene and preferentially selects to access the terrestrial network, the number of 4G base stations at the current location of the user equipment is small, and the number of 3G base stations is small, so the user equipment will access the 3G mobile network as a final mobile communication network.
Of course, if the ue is in a city use scenario and the access to the terrestrial network is preferred, but the current location of the ue is remote or the bs signal cannot be effectively served due to architectural reasons, the ue may switch to the non-terrestrial network.
S310, according to the selected mobile communication network, screening out candidate cells meeting the cell selection criterion;
s320 obtains the signal strength of each candidate cell, and selects the candidate cell with the highest signal strength as the target cell for camping.
Specifically, the radio resources are configured on a cell basis, and a cell is an area covered by radio resources provided by a NodeB. The user equipment establishes a radio channel for transceiving data by using a radio resource of a cell in which the user equipment is located.
When the user equipment does not establish a dedicated radio channel, a cell reselection will be triggered if it moves from one cell to another. In the process of cell reselection, the user equipment measures the signal strength and signal quality received from adjacent cells, compares the signal strength, and finally selects a cell. The purpose of cell reselection is to find exactly the best cell in which the user equipment can camp and take service.
When the user equipment does not establish a dedicated radio channel, a cell reselection will be triggered if it moves from one cell to another. In the process of cell reselection, the user equipment measures the signal strength and signal quality received from adjacent cells, compares the signal strength, and finally selects a cell. The purpose of cell reselection is to accurately find the best cell for camping in which the user equipment can camp and acquire service.
According to the embodiment, when the user equipment triggers the cell reselection process, a proper mobile communication network is selected according to different use scenes for cell reselection, so that the user equipment can select a proper cell to initiate reconstruction, the continuity of data services of the user equipment is ensured, the performance of the mobile terminal is effectively improved, the processing process is simple and rapid, the working performance is stable and reliable, and the application range is wide.
And secondly, the user equipment selects the candidate cell with the maximum signal strength as the target cell to reside, so that the cell reselection process can be accelerated, the user equipment can camp on the cell with better signal quality as soon as possible, the communication performance of the user equipment is effectively improved, and the processing process is simple and rapid.
In addition, when the selective reception level value is less than or equal to the preset threshold value, the cell reselection function is determined to be triggered, so that the cell reselection times of the user equipment are reduced, the power consumption of the user equipment is reduced, and the endurance time of the user equipment is prolonged.
For example, as shown in fig. 4, assuming that the current location of the User is a desert area, a UE (User Equipment) is powered on and resides in a satellite network. The user can manually set the current usage scenario of the current UE to a remote area. At this time, the UE detects the selected reception level value by itself, if the selected reception level value is Srxlev < RSRP threshold value (assumed to be-95 dB), the UE triggers NTN to reselect the neighbor cell measurement, and the UE reselects a new serving cell according to the signal strength of the candidate cell and resides in the reselected serving cell.
