Description

Communication method and device

Technical Field

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the present application, unless otherwise specified, "at least one" means one or more, and "a plurality" means two or more. In addition, in order to facilitate clear description of technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish identical items or similar items with substantially identical functions and actions. Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.

With the development of society, more and more travel tools can be selected by people. Among them, some travel tools mainly travel on fixed routes, such as: train lines, high-speed rail lines and highways. However, it is not difficult to find that the speed of the network is very low and even the mobile communication equipment such as a mobile phone is not available on a train, a high-speed rail and an automobile, and the communication quality is very poor when the mobile communication equipment such as the mobile phone is used for surfing the internet or making a call. Therefore, information inquiry, exchange and sharing of people in the traveling process are greatly influenced, time and resources are wasted, and the life of people is seriously disturbed due to lack of real-time information inquiry and transmission.

For this case, some operators may consider deploying a dedicated network for fixed lines, for example, for high-speed railway lines. However, the deployment cost of the private network is high, and it is not possible to cover all fixed lines, and the deployed private network is also interfered by a nearby non-private network, and it is difficult to ensure the communication quality.

Alternatively, when the electronic device is used to connect to a network, a cell having a high speed cell indicator (HSF) is selected to preferentially camp on. The HSF cell is also preferably selected at the time of cell handover (handover). This approach is only effective for cells that have HSFs on fixed lines all the time. However, on a fixed line, it cannot be guaranteed that the connection to the HSF cell is always possible, and therefore, the communication quality cannot be guaranteed.

Therefore, in the communication method provided in the embodiment of the present application, a cell mapping table is set in advance, where the cell mapping table includes a plurality of preset travel routes and a plurality of black cell lists corresponding to each of the plurality of preset travel routes. And then determining the current travel route of the user, and matching the current travel route of the user with the routes in the plurality of preset travel routes, so as to configure a blacklist cell for the current travel route of the user according to the matched route. And finally, the terminal equipment is connected to the service cell with better quality according to the blacklist cell. Therefore, when the electronic equipment searches the cell, the electronic equipment can avoid the cell with poor communication quality from being directly connected to the preferred cell, and therefore communication experience of a user is improved.

In a possible embodiment, a network device serving a terminal device is a serving cell, and the terminal device is a UE, for example, a flowchart of a communication method provided in this embodiment may be as shown in fig. 4. Referring to fig. 4, the communication method may include the steps of:

step 401, the UE presets a cell mapping table.

The cell mapping table may only include a plurality of preset travel routes and a plurality of black cell lists (i.e., a first cell list) corresponding to each of the preset travel routes. It is also possible to include only a plurality of preset travel routes and a plurality of preferred cells (i.e., second cells) corresponding to each of the plurality of preset travel routes. Or the mobile terminal comprises a plurality of preset trip lines and a plurality of black cell lists and a plurality of preferred cells corresponding to each preset trip line in the preset trip lines.

The preset travel routes can be high-speed rail routes, highway routes, train routes and the like. Each preset trip line corresponds to a plurality of preset places, and each preset place in the plurality of preset places corresponds to one preferred cell and one black cell list. Each preferred cell is a cell with the best signal quality around the preset place corresponding to the preferred cell. And the cell in each black cell list is a cell except for the cell with the best signal quality around the preset position corresponding to the black cell list. If only one cell can be connected to the preset place, the cell is the preferred cell, and the black cell list is empty.

Usually, the preset trip line is mostly very long, from hundreds of kilometers to thousands of kilometers. The distance between any two base stations is relatively short, essentially a few hundred meters to a few hundred kilometers. When the travel tool travels on a preset travel line, multiple base stations can be accessed. In order to ensure that the electronic devices on the travel tool can communicate normally, a plurality of preset places in the preset travel route are set based on the distance between the base stations.

Illustratively, the distance between every two adjacent preset locations in the plurality of preset locations is smaller than a preset threshold, and the preset threshold is determined according to the distance between two target base stations. One target base station is a base station closest to one of the two adjacent preset points, and the other target base station is a base station closest to the other of the two adjacent preset points. For example, on a high-speed railway from beijing to sika, the zheng zhong station is one of a plurality of preset locations, the preset location a is a preset location adjacent to the zheng zhong station, and the distance between the zheng zhong station and the preset location a is less than a preset threshold value. The preset threshold is calculated from base station X and base station Y. The base station X is the closest base station to the zhengzhou east station, and the base station Y is the closest base station to the preset location a. The preset location may be reset according to the actual situation, which is not limited in this application.

The preferred cells and black cell lists corresponding to each preset trip line may be determined by a worker using the UE to perform cell signal testing at each preset location on each preset trip line. And according to the test result of the cell signals, taking the cell with the best signal as a preferred cell, and taking other cells except the preferred cell as the cells in the black cell list. The cell Signal may be determined by parameters such as Reference Signal Receiving Power (RSRP), reference Signal Received Quality (RSRQ), received Signal Strength Indicator (RSSI), signal-to-noise ratio (SNR), uplink rate, and downlink rate.

For example, the staff uses the UE to perform network connection at a preset location a of a preset travel route B. In the network connection process, the network can be connected to a preset place a through 3 cells (b, c and d), then the signal strength of the 3 cells is tested, according to the test result, the cell b with the strongest signal is used as a preferred cell, and other cells c and d are used as black cells. As shown in fig. 5, for the preset travel route B, a label 11 is used to identify a preferred cell, and a label 12 is used to identify a cell in the black cell list. And finally, supplementing the preset travel line B, the preferred cell and the black cell list into a cell mapping table. When the UE searches for the network later, the UE may refer to the black cell list in the cell mapping table, and does not perform network camping when searching for a cell in the black cell list, so that the UE is only connected to the preferred cell. Therefore, the cell residence trying time of the UE is greatly reduced, frequent switching is avoided, the terminal equipment can be rapidly resided in a proper cell, and poor communication quality and electric quantity consumption caused by frequent switching are avoided.

The plurality of preferred cells and the plurality of black cell lists corresponding to each preset trip line are sequentially arranged according to the trip direction of the preset trip line.

In some embodiments, taking a preferred cell including only the preset travel route 1 and the preset travel route 2 in the cell mapping table as an example, the cell mapping table may be as follows:

}

optionally, the preset trip lines in the cell mapping table preset by the UE may be all the tested preset trip lines, or may be screened out through intelligent learning. The preset trip lines screened out through the intelligent learning are far less than all tested preset trip lines, and the preset trip lines screened out based on the intelligent learning are more in line with the trip habits and trip requirements of users.

The process of screening the preset travel route based on intelligent learning may be: the travel route of the user in recent years is obtained through map application, ticket buying application, travel application and other travel-related applications in the UE. And then screening out fixed lines from the travel lines, sequencing all the fixed lines according to the travel frequency of the fixed lines, determining the fixed lines meeting the requirements according to the sequencing result, and finally establishing a cell mapping table by taking the fixed lines meeting the requirements as preset travel lines. The fixed line meeting the requirement may be a fixed line in the sorting result, the sorting order of which exceeds a preset threshold. Because many fixed lines exist in China, if all the fixed lines are stored in the UE of the user, a large storage pressure is brought. The fixed line may include a train line, a high-speed rail line, a highway line, and the like.

Therefore, the method and the device can only store the fixed line meeting the requirement in the UE based on intelligent learning. Therefore, the cell mapping table obtained according to the fixed line meeting the requirements is high in use frequency, and the storage pressure of the UE can be reduced.

The preset travel route can also be changed along with the travel habits of the user, for example, the user is moved from city C to city D for working reasons. And the UE determines that the user is located in the city C through a positioning function, determines a first line based on the travel track of the user in the city C, and generates a first cell mapping table based on the first line. After a period of time, the UE determines that the travel data of the user in the D city exceeds a preset threshold, for example, the travel time exceeds a preset time, or the travel mileage exceeds a preset kilometer number, and determines the second route based on the travel track of the D city. And generating a second cell mapping table based on the second line. The second cell mapping table may include data of the first line, or may replace the data of the first line with the data of the second line.

Or, the preset trip route may also guide the user to input the route to be tripped into the UE in an interactive manner. And then the UE establishes a cell mapping table according to the line input by the user.

Step 402, the UE determines the travel information of the user.

Among them, the travel information of the user may include a travel route (i.e., a first travel route), a travel direction (i.e., a travel direction of the first travel route), a travel tool currently taken by the user, and a cell (i.e., a third cell) in which the UE currently resides.

The travel tools that the user currently rides on may be high-speed rails, trains, cars, and the like. The cell in which the UE currently resides is the cell in which the UE is connected to the network.

Specifically, step 402 includes the following substeps:

step 4021, the UE determines whether the user is currently going out on the fixed line.

Whether the user is currently going out on a fixed line or not can be determined according to the current moving speed of the user and the current positioning information of the user.

Currently, most users carry UEs with them, such as: provided is a mobile phone. Because the mobile phone is internally provided with the acceleration sensor, the current moving speed of the user can be determined according to the acceleration sensor in the mobile phone. According to the current moving speed of the user, the travel tool currently taken by the user can be preliminarily presumed.

If the current moving speed of the user falls within the driving speed range of the high-speed rail, the user may be considered to be a high-speed rail on which the travel tool is taken. In general, the driving speed ranges of high-speed trains are: 150-400 km/h. If the current moving speed of the user is within the running speed range of the train, the user is considered to be possibly the train. The running speed range of the train is as follows: 90-110 km/h. If the current moving speed of the user is within the running speed range of the train, the user is considered to be possibly the train. The driving speed range of the automobile is as follows: 60-120 km/h. If the current moving speed of the user falls within the driving speed range of the automobile, the user may be considered to be the automobile as the travel tool taken by the user.

Then, the current position information of the user is determined, wherein the current position information of the user can be determined through a Global Navigation Satellite System (GNSS) built in the mobile phone. GNSS information may include Global Positioning System (GPS) information, global navigation satellite system (GLONASS) information, beidou satellite navigation system (BDS) information, quasi-zenith satellite system (QZSS) information, and/or Satellite Based Augmentation System (SBAS) information, among others.

Alternatively, the current location information of the user may also be determined by the cell ID. Specifically, each Cell has a Global Cell identity (CGI). Through inquiring CGI of a cell providing a communication function for the mobile phone, longitude and latitude information of the cell can be obtained according to the CGI, and therefore position information of a user is determined.

Still alternatively, the current location information of the user may also be determined by a high speed cell flag (HSF). The HSF identifier is used to identify a high-speed rail cell, and if the cell to which the UE is connected has the HSF identifier, it indicates that the user is located near the high-speed rail.

Finally, after the current moving speed and the current position information of the user are determined, whether the user is currently going out on a fixed line or not can be determined.

For example, if it is determined that the user is located on a high-speed rail according to the current location information of the user and the current moving speed of the user is within the driving speed range of the high-speed rail, the user is considered to be traveling on the fixed line of the high-speed rail. For example, when the user is located near the XX high-speed railway station on the high-speed railway and the moving speed of the user is 280 km/h, the user is considered to be currently traveling on the fixed railway of the high-speed railway.

And if the user is determined to be located on the high-speed rail and the moving speed of the user is not within the driving speed range of the high-speed rail, the user is not considered to travel on the fixed line. The user is located on the high-speed rail, but the moving speed of the user does not fall within the driving speed range of the high-speed rail, possibly because the user is a worker at the high-speed rail station.

And if the user is determined to be located on the train line through the current position information of the user and the current moving speed of the user is within the running speed range of the train, the user is considered to travel on the fixed line of the train. For example, when the user is located near XX railway station on a train line and the current moving speed of the user is 100km/h, the user is considered to travel on a fixed line of the train.

And if the user is determined to be located on the train line and the moving speed of the user is not within the running speed range of the train, the user is not considered to be on the fixed line.

And if the user is determined to be located on the expressway through the current position information of the user and the current moving speed of the user is within the driving speed range of the automobile, the user is considered to be traveling on the expressway. For example, when the user is located near the XX expressway intersection on the expressway line and the current moving speed of the user is 100km/h, the user is considered to travel on the fixed line of the expressway.

And if the user is determined to be located on the expressway, and the moving speed of the user is not within the driving speed range of the automobile, the user is not considered to travel on the fixed line.

In some embodiments, determining whether the user is currently traveling on the fixed line may further be performed by detecting whether a cell where the user resides changes within a preset time and the number of changes. The speed is higher because the travel tool is in the process of traveling. And if the cell where the user resides is not changed within the preset time, the user is not considered to be traveling on the fixed line currently. If the cell where the user resides is changed within the preset time, but the changing times are lower than the preset times, the user is also considered not to travel on the fixed line currently. And if the cell where the user resides is changed within the preset time and the changed times are more than or equal to the preset times, determining that the user currently goes out on the fixed line. The preset times can be determined according to the running speed of a high-speed rail, the running speed of a train or the running speed of an automobile.

In other embodiments, whether the user is currently traveling on a fixed line may be determined in an intelligent learning manner. The method comprises the following steps: the UE may detect that the user purchased a travel credential in travel-related applications such as a map application, a ticketing application, and a travel application. And then extracting the travel information in the travel voucher, wherein the travel information can comprise travel time, travel tools and travel routes. And then, detecting whether the user goes out according to the trip information by using an acceleration sensor and a positioning system in the UE, and if the user goes out according to the trip information, obtaining whether the user currently goes out on a fixed line.

Illustratively, the cell phone detects that the user purchased a high-speed rail ticket at the ticket-buying platform. According to the purchased high-speed railway tickets, the user is confirmed to start at the E high-speed railway station at 14 o 'clock in the afternoon of the day by taking a GXXX train and arrive at the F high-speed railway station at 16 o' clock and 30 min. And then, at 14 o ' clock, the mobile phone detects whether the position information of the user is located at the E high-speed rail station, and at a time period of 30 minutes from 14 o ' clock to 16 o ' clock, the mobile phone detects whether the moving speed of the user falls within the driving speed range of the high-speed rail at variable time. And if the user is located at the E high-speed rail station and the detected moving speed is within the driving speed range of the high-speed rail, the user is considered to be currently going out on the fixed line.

Step 4022, if the user currently travels on the fixed line, determining the cell where the UE currently resides, and determining the travel information of the user according to the currently residing cell and the cell mapping table.

The trip information of the user comprises a trip route and a trip direction of the trip route.

In some embodiments, if the user is currently traveling on the fixed line, the cell (i.e., the third cell) in which the UE currently resides may be determined by querying.

In the case that the cell mapping table includes a plurality of preferred cells and a plurality of black cell lists corresponding to each of a plurality of preset travel lines, a cell where the UE currently resides is searched for in the plurality of preferred cells and the plurality of black cell lists corresponding to each of the plurality of preset travel lines, and a line corresponding to the searched cell including the UE currently resides is used as a travel line (i.e., a first travel line) of the user.

And if the searched lines corresponding to the cell containing the current resident UE have a plurality of lines, continuously acquiring other cells where the UE resides. And then determining the trip route of the user according to the cell where the UE currently resides and other cells where the UE resides.

Specifically, after the cell where the user currently resides is determined, the UE is in a mobile state all the time because the user currently travels on a fixed line, and after a period of time, the UE resides in the next cell. Then, according to the cell where the UE currently resides and the cell where the UE resides next (i.e., the fourth cell), the cell where the UE currently resides and the cell where the UE resides next are searched in a plurality of preferred cells and a plurality of black cell lists corresponding to each of a plurality of preset travel routes, and the searched lines including the cell where the UE currently resides and the cell where the UE resides next are used as the travel routes of the user.

If the searched lines including the cell where the UE currently resides and the cell where the UE resides next are still multiple, the cell where the UE resides after the cell where the UE resides next is continuously obtained until a unique fixed line is determined according to the cell where the UE currently resides, the cell where the UE resides next and the cell where the UE resides after the cell where the UE resides next, and the determined unique fixed line is the trip line of the user.

After the travel route of the user is determined, the travel direction of the travel route is determined according to the travel route of the user, the residence time of the UE in the cell where the UE resides currently and the residence time of the UE in the cell where the UE resides next. Specifically, the travel direction of the travel route is determined according to the order of the cells in the plurality of preferred cells or the plurality of black cell lists corresponding to the travel route of the user, the residence time of the UE in the cell where the UE currently resides, and the residence time of the UE in the cell where the UE resides next.

Or, determining the traveling direction of the traveling line according to the traveling line of the user, the residence time of the UE in the currently residing cell, the residence time of the UE in the next residing cell, and the residence time of the UE in the cell residing behind the next residing cell. Specifically, the travel direction of the travel route is determined according to the sequence of the cells in the plurality of preferred cells or the plurality of black cell lists corresponding to the travel route of the user, the residence time of the UE in the cell where the UE currently resides, the residence time of the UE in the cell where the UE resides next, and the residence time of the cell where the UE resides after the cell where the UE resides next. According to actual conditions, the traveling direction of the user can be determined in other manners, and the traveling direction is not limited by the application.

Step 403, the UE performs cell setting on the trip route of the user to obtain a blacklist cell corresponding to the trip route.

The blacklist cell comprises a current preset place and cells in a cell list corresponding to N preset places behind the current preset place.

After the travel route and the travel direction of the travel route are determined, because the determined travel route is the same as one travel route in the cell mapping table, and a plurality of preferred cells and a plurality of black cell lists corresponding to the travel route in the cell mapping table are known, a plurality of preferred cells and a plurality of black cell lists corresponding to the travel route of the user are known.

Matching the cell where the UE currently resides with a plurality of preferred cells and a plurality of black cell lists corresponding to the trip route of the user to obtain one or more target preferred cells. And then setting all the preferred cells behind the matched one or more target preferred cells as preferred cells corresponding to the trip route according to the trip direction of the trip route, and setting the cells in the black cell list behind the matched one or more target preferred cells into the black list cells corresponding to the trip route.

Or, the UE sets only the blacklist cell corresponding to the travel line. Specifically, the UE sets a cell in a blacklist cell list after the matched one or more target preferred cells to a blacklist cell corresponding to the travel route according to the travel direction of the travel route. And then, on the trip line, when the UE scans the cell, comparing the scanned cell with the blacklist cell, and if the scanned cell is consistent with the blacklist cell, continuing to scan. If not, connecting to the scanned cell.

Or, the UE sets only a preferred cell corresponding to the travel route. Specifically, the UE sets all preferred cells after the matched one or more target preferred cells as preferred cells corresponding to the travel route according to the travel direction of the travel route. And then, on the trip line, after the UE scans the cell, comparing the scanned cell with the preferred cell, if the scanned cell is consistent with the preferred cell, connecting to the scanned cell, and if the scanned cell is inconsistent with the preferred cell, continuing to scan.

Optionally, the blacklisted cell corresponding to the travel route further includes: and black cells adjacent to the matched one or more target preferred cells.

It should be noted that, because the number of cells in the blacklist cell has an upper limit, the cells in the blacklist cell need to be updated and replaced in time along with the travel of the travel tool, so that the blacklist cell corresponding to the preset location is set in advance before the next preset location arrives.

For example, for a high-speed rail line from Beijing to Xian, it is assumed that each station is a preset site. Then the highspeed railway line from beijing to dian includes several predetermined locations including beijing west station, a certified east station, shijiazhuang station, a dongcheng station, a handan dong station, an agrimonial dong station, a zhengzhou dong station, a luoyang longmen station, a north huashan station, and a north west ann station.

If the high-speed rail is currently in the Shijia village station, cells in blacklisted cells corresponding to the Dong station of the Handan, the Dong station of the He mura, the Dong station of the Zheng state and the Longmen station of the Luoyang can be set firstly due to the limited cell data in the blacklisted cells. Along with the running of high-speed rails, cells corresponding to the Dong station and the Handan station in the blacklist cells can be deleted, and cells corresponding to the North China station and the North Western Anshan station are arranged in the blacklist cells. Therefore, the cells in the blacklist cells are set in advance before the next preset place arrives, and the UE is prevented from residing in the cells in the blacklist cells.

And step 404, on the trip route, the terminal device is connected to the serving cell based on the blacklist cell.

The service cell is a cell except a cell in the blacklist cell corresponding to the trip line.

When the UE is driving on the outbound line, the UE can only connect to cells other than the cells in the blacklist of cells. Corresponding to leaving only one preferred cell at each preset location of the travel route. Therefore, the UE can only be connected to the optimal cell with the best signal at each preset place, the problems of poor communication quality and high power consumption of the UE caused by frequent switching of the cells are solved, and the network use experience of a user can be improved.

And 405, if the user does not travel on the travel line currently, the terminal equipment clears the blacklist cell.

When the user is not going on the outgoing line, it indicates that the cell where the UE resides will not be frequently switched, so the above-mentioned blacklisted cell will not be needed any more.

The user's absence of travel on the outbound route may be determined in a number of ways. For example, the moving speed of the mobile phone is measured by an accelerator in the mobile phone, and when the moving speed is less than a first threshold, the user is considered not to travel on the travel line. The first threshold may be a speed range corresponding to pedestrian walking or a speed range in which an automobile moves.

The user can also be determined by intelligent learning and speed measurement when not going out on the outgoing line. For example, the mobile phone detects that the user purchases a high-speed rail ticket (or a train ticket or a bus ticket) at the ticket purchasing platform. And then determining the travel time, travel tools, travel routes and arrival time of the user according to the purchased high-speed railway tickets. When the arrival time arrives, it is detected whether the moving speed of the user falls within a traveling speed range at which the pedestrian walks. If the moving speed of the user falls within the traveling speed range of the pedestrian walking, the user is considered not to travel on the travel route.

And when the UE does not travel on the travel line, clearing the blacklist cell, and selecting the cell to reside by the UE according to a conventional mode.

Hereinafter, a drive calling method provided in the embodiments of the present application will be described in detail with reference to the drawings. As shown in fig. 6, the method comprises the steps of:

step 601, the terminal device determines the trip information of the user.

The trip information includes a first trip line, the first trip line belongs to one of a plurality of preset trip lines, each preset trip line of the plurality of preset trip lines corresponds to a plurality of first cell lists, each preset trip line corresponds to a plurality of preset places, each preset place of the plurality of preset places corresponds to one first cell list, and each first cell list includes cells except for the cell with the best signal quality around the preset place corresponding to the first cell list. See step 402, step 4021, and step 4022 for details.

Step 602, the terminal device determines a first serving cell of a first preset location in a plurality of preset locations corresponding to the first trip route.

The first service cell is a cell outside a blacklist cell, and the blacklist cell comprises a first preset place and cells in a first cell list corresponding to N preset places behind the first preset place.

The first trip route includes a plurality of preset places, and the first preset place is a place closest to the current position of the user. And then, according to a blacklist cell corresponding to a preset first trip line, the UE is connected to the first service cell at a first preset place. See steps 403 and 404 for details.
