Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

With the development of mobile communication technology and the popularization of computer technology, Location-Based Service (LBS) technology is moving into people's lives. By using the LBS technology, the position of the mobile terminal can be obtained by positioning the mobile terminal, and then the service related to the position of the mobile terminal is provided for the mobile terminal.

In recent years, Geo-fencing (Geo-fencing) technology has attracted more and more attention as a new application of LBS technology. Geofencing techniques may use a virtual fence to enclose a geofence. Notifications and prompts corresponding to the geofence may be received when the mobile terminal is active in or near the geofence. For example, when a mobile terminal enters a geofence, a merchant located in the geofence may send promotional, preferential, or novelty information to the mobile terminal.

The electronic certificate prompting method and the server in the embodiment of the application use the geo-fencing technology. The electronic voucher comprises a group purchase ticket, a coupon, a voucher, an electronic value-stored card, an electronic ticket, an electronic pass, an electronic access card and the like. The content of the electronic certificate comprises the type of the electronic certificate, the valid time of the electronic certificate, the code of the electronic certificate, the password and the like.

An embodiment of the electronic certificate prompting method of the present application is described below. As shown in fig. 1, includes:

s101: the first server establishes corresponding relations between the electronic certificate and the geo-fence and between the electronic certificate and the mobile terminal identification.

The electronic voucher is typically an electronic voucher of a third party. The third party includes a merchant, a civil aviation airport, a railway station, a parking lot, etc. that provides services for the electronic voucher.

The first server is typically the server that generates the electronic certificate. The third party may upload the relevant information needed to generate the electronic voucher to the first server. And the first server acquires the related information uploaded by the third party, and can generate the electronic certificate according to the related information after receiving a request of acquiring the electronic certificate by the mobile terminal. For example, when the electronic voucher is a coupon, the related information includes a kind of the coupon (for example, a coupon of a kind of full 100 minus 50, full 300 minus 200, etc.), a usage time of the coupon, a usage method of the coupon, and the like.

The first server can obtain a geographic location of a third party and establish a geofence associated with the third party based on the geographic location. For each geofence, the first server may generate a geolocation code. The geo-location codes for different geo-fences are typically not identical. Thus, for each third party, the first server may establish a correspondence of its geographic location to the geographic location code of its geofence. For example, where the third party is a merchant, the first server will establish a geo-fence for the merchant and generate a geo-location code for the merchant geo-fence. The geographic location of the third party may be latitude and longitude (latitude and longitude). For the specific processes of establishing the geo-fence and generating the geo-location code, please refer to the following detailed description.

The mobile terminal may request the first server for an electronic certificate of the third party. The first server can generate an electronic certificate of a third party according to the request of the mobile terminal, and can send the electronic certificate to the mobile terminal. The mobile terminal is typically the holder of the electronic voucher. The mobile terminal may include various terminal devices having a positioning function. For example, a smart phone, a tablet computer, an electronic chip with a positioning function, and a wearable device integrating the electronic chip, etc. The Positioning function may be implemented by a GPS (Global Positioning System), a BDS (bei dou navigation Satellite navigation System), a GLONASS (GLONASS Satellite navigation System), a Galileo Satellite navigation System (Galileo Satellite navigation System), a base station Wireless signal, a WIFI (Wireless-Fidelity) signal, a Bluetooth (Bluetooth) signal, or any combination of the above.

The Identity of the Mobile terminal generally includes a MAC (Medium/Media Access Control) address, an IMEI (International Mobile Equipment Identity), a phone number, and the like. In some cases, the identity of the mobile terminal may also include an account number, a user code, an identification number, and the like. For example, a client of a third party is installed on the mobile terminal. The user registers an account number in the client using the mobile terminal. Then, because the account number of the third party is stored in the mobile terminal, a corresponding relationship is established between the mobile terminal and the account number of the third party, and the account number can be used as the identifier of the mobile terminal. Further, if the user uses the identification number when registering the account number, a corresponding relationship is established between the identification number and the account number of the third party, so that a corresponding relationship is also established between the identification number and the mobile terminal, and the identification number can be used as the identifier of the mobile terminal.

After receiving a request of the mobile terminal for acquiring the third-party electronic certificate, the first server acquires the identifier of the mobile terminal and generates the electronic certificate, so that the corresponding relation between the identifier of the mobile terminal and the electronic certificate can be established. For example, the electronic voucher is a coupon full of 100 minus 50, and the identification of the mobile terminal is a telephone number. Then, after receiving the request of the mobile terminal, the first server acquires the telephone number of the mobile terminal, generates a coupon of which the number is 100 minus 50, and establishes a corresponding relation between the telephone number and the coupon. The first server can inquire the coupon through the telephone number.

As another example, the electronic voucher is a 100 minus 50 coupon and the identity of the mobile terminal is an account number of the third party. Then, after receiving the request of the mobile terminal, the first server acquires the account number of the third party of the mobile terminal, and generates a coupon with the account number of 100 minus 50 according to the account number, thereby establishing the corresponding relationship between the account number and the coupon. The first server can inquire the coupon through the account number.

The first server can establish the corresponding relation between the mobile terminal identification and the electronic certificate and also can establish the corresponding relation between the geographic fence and the electronic certificate. The specific process is as follows.

Because the electronic certificate is generally an electronic certificate of a third party, the first server establishes a corresponding relationship between the third party and the electronic certificate. And for the third party, the first server also establishes the corresponding relation between the geographic position of the third party and the geographic position code of the geographic fence. Thus, the first server can establish a correspondence between the geo-location code of the geo-fence and the electronic credential, thereby establishing a correspondence between the geo-fence and the electronic credential.

The following describes a process in which the first server establishes a geo-fence based on the geo-location of the third party and generates a geo-location code for the geo-fence.

After acquiring the geographic position of the third party, the first server divides the geographic position within a preset range into a geographic area according to a preset rule, so as to establish a geographic fence. Each geo-fence corresponds to a unique geo-location code. The preset rules comprise a tail-removing algorithm and a geohash algorithm.

The tail-removing algorithm is explained as an example.

And the first server carries out ending processing on the latitude and longitude of the third-party geographic position, takes the geographic range represented by ending latitude and longitude as a geographic fence, and takes the ending latitude and longitude as the geographic position code of the geographic fence. Such as a third party geographic location having a latitude of 39.928167 and a longitude of 116.389550. And (4) carrying out tail removing processing on the longitude and latitude, for example, completely removing the second position and the subsequent content after the decimal point. The trailing latitudes and longitudes after treatment by the method are 39.9 and 116.3 respectively. The first server takes the geographical range represented by latitude 39.9 and longitude 116.3 as a geo-fence. Obviously, the longitude and latitude of two geographical positions close enough can be processed by the same tailing-out longitude and latitude after tailing-out processing. For example, the longitude and latitude of the third-party geographical position are (39.928167, 116.389550), the longitude and latitude of the geographical position close to the third-party geographical position are (39.925014, 116.3893215), and after the respective tail removing processing, the tail removing longitude and latitude are all (39.9, 116.3). Then, these nearby geo-locations can be classified into the same geofence, and the tailed latitudes and longitudes of the geo-locations in the geofence are all the same. From the above description, it can be seen that the accuracy of the tail-ending process determines the extent of the final defined geofence. For example, the higher the accuracy of the tail-removed longitude and latitude (the more digits after the decimal point), the smaller the final defined geofence range will be; accordingly, the lower the precision of the tailed latitude (the fewer the number of bits after the decimal point), the larger the geofence range that will ultimately be defined.

The geohash algorithm is described as an example.

The first server may map the latitude and longitude of the third party geographic location to a geohash value using a geohash algorithm. If the third party geographic location has a latitude of 39.928167 and a longitude of 116.389550.

The latitude 39.928167 is approximately encoded by the following algorithm:

1) the latitude interval of the earth is divided into two intervals of-90, 0 and 0, 90.

Two sections into which one section is divided are referred to as left and right sections, respectively. The left interval is the interval where the smaller numerical value is located, and the right interval is the interval where the larger numerical value is located. Further, the latitude is marked by the following rule:

for those belonging to the right interval, labeled 1; for those belonging to the left interval, the label is 0.

Thus, 39.928167 belongs to the right interval [0, 90], labeled 1 according to the above rules.

2) The right interval [0, 90] of 39.928167 is divided into two intervals [0, 45 ], 45, 90.

Decision 39.928167 belongs to the left interval [0, 45), labeled 0.

3) The above procedure of step 1) and step 2) was recursed as in table 1 below until the predetermined number of bits was marked.

According to the foregoing rule, the latitude 39.928167 may be marked as 1 when it belongs to the right of the two-dimensional interval and may be marked as 0 when it belongs to the left.

As the interval is narrowed down for each iteration, the median value of the interval (Mid value in table 1) approaches 39.928167 more and more;

and dividing the interval by a certain number of times, judging the relation between the latitude value and the divided interval and marking the relation, so as to obtain a serial number consisting of 0 and 1, wherein the length of the serial number is related to the number of times of dividing the interval by two. Table 1 lists the interval iterations at a latitude of 39.928167.

TABLE 1 Interval stack at 39.928167 degrees

Bit	Min	Mid	Max
				1	-90.000	0.000	90.000
0	0.000	45.000	90.000

1	0.000	22.500	45.000
				1	22.500	33.750	45.000
1	33.750	39.375	45.000
				0	39.375	42.188	45.000
0	39.375	40.7815	42.188
				0	39.375	40.07825	40.7815
1	39.375	39.726625	40.07825
				1	39.726625	39.9024375	40.07825

As shown in table 1, after 10 iterations of the interval, a serial number 1011100011 (labeled values are arranged from left to right in sequence) corresponding to a latitude of 39.928167 is finally obtained, and the latitude interval has been narrowed to [39.9024375, 40.07825 ].

With the same method, through 10 iterations of the interval, a sequence number 1101001011 corresponding to a longitude of 116.389550 can be obtained, and the longitude interval has been narrowed to [116.3671875, 116.71875 ].

The first server takes the geographical range represented by the latitude interval [39.9024375, 40.07825] and the longitude interval [116.3671875, 116.71875] as the geo-fence.

And the first server encodes serial numbers corresponding to the longitude and the latitude to generate a geohash value corresponding to the longitude and the latitude. The coding method comprises the following steps: and sequentially and mutually interpolating the serial numbers corresponding to the longitude and the latitude to generate a new serial number. The first digit of the newly generated sequence number is the first digit of the sequence number corresponding to longitude.

For example, when the serial number corresponding to latitude is 1011100011 and the serial number corresponding to longitude is 1101001011, a new serial number such as 11100111010010001111 can be formed by sequentially interpolating serial numbers corresponding to longitude and latitude with the first digit of the serial number corresponding to longitude as the first digit of the newly generated serial number. The odd-numbered digits of the newly generated serial numbers from left to right are serial numbers corresponding to longitude, and the even-numbered digits are serial numbers corresponding to latitude.

The first server base32 encodes the newly generated serial number using 32 characters 0-9, b-z (minus a, i, l, o). The correspondence between the 32 characters 0 to 9, b to z and the decimal number is shown in Table 2.

TABLE 2 decimal number to Base32 code correspondence

Dec	0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15
																	B32	0	1	2	3	4	5	6	7	8	9	b	c	d	E	F	g
Dec	16	17	18	19	20	21	22	23	24	25	26	27	28	29	30	31
																	B32	H	j	k	M	n	P	Q	r	s	t	u	v	w	X	Y	z

Note: dec stands for Decimal, denoting Decimal; b32 represents Base32 code.

When encoding a new serial number, firstly, every five digits in 11100111010010001111 can be converted into decimal numbers, namely 28, 29, 4 and 15; the 4 decimal numbers are then encoded using the correspondence in table 2. 28 for w, 29 for x, 4 for 4, 15 for g, wx4g is obtained. Wx4g was taken as the geohash value for latitude and longitude (39.928167, 116.389550). The first server encodes the geohash value as a geo-location of the geofence.

In the above-described geohash algorithm, the number of iterations determines the length of the generated sequence number, and thus the length of the finally generated geohash value. The longer the geohash value is, the more the number of times of iteration is represented, and the final interval is closer to the actual longitude and latitude. In other words, the more bits of the geohash value, the smaller the geographic extent of the geofence.

Meanwhile, under a certain number of iterations, that is, under the premise of a certain length of the geohash value, if two geographic positions are relatively close, the geohash values corresponding to the longitude and latitude are also the same or relatively close. For geographic locations with the same geohash value, the geographic locations may be classified into the same geofence. The geo-hash value of the geofence can be used as the geo-location code for the geofence. Fig. 2 is a diagram illustrating the division of the geographical location within the preset range according to the geohash value in an embodiment of the present embodiment. As can be seen from fig. 2, the geographic locations within the preset range are divided into 9 rectangular areas, and the geographic locations in each rectangular area have a unique geohash value. These 9 rectangular areas can be used as the divided geofences.

In some embodiments, the first server saves each generated electronic voucher accordingly. The electronic certificate stored in the first server is used for counting the acquired and used electronic certificates respectively and returning the related statistical data to the third party. For example, if the electronic voucher is a coupon, the coupon picked up by the user through the first server may not be used. The first server can calculate the proportion of the consumption ticket used by the user to the generated consumption ticket and return the proportion to the third party, thereby providing data support for the production operation activity of the third party.

S102: the mobile terminal uploads the geographical position and the identification of the mobile terminal to the first server.

The mobile terminal can acquire the geographic position and the identification of the mobile terminal, and upload the acquired geographic position and the identification to the first server. The geographic position of the mobile terminal is generally the longitude and latitude of the geographic position of the mobile terminal. The type of the mobile terminal identity is the same as the mobile terminal identity in step S101.

There are various methods for acquiring the geographical location of the mobile terminal, including but not limited to:

acquiring the geographical position of the satellite navigation system (such as a GPS, BDS, GLONASS or Galileo satellite navigation system);

acquiring the geographical position of the mobile communication base station through a signal of the mobile communication base station;

and acquiring the geographical position of the WIFI equipment or the Bluetooth equipment of the third party.

There are various methods for the mobile terminal to obtain the self-identity, including but not limited to:

if the identifier of the mobile terminal in the step S101 is a phone number, the mobile terminal acquires its own phone number;

if the identifier of the mobile terminal is the IMEI code in the step S101, the mobile terminal acquires the IMEI code of the mobile terminal;

if the identifier of the mobile terminal in the step S101 is the account number of the third party; the mobile terminal obtains the account number of the third party.

There are various methods for the mobile terminal to upload its geographical location and identity to the first server, including but not limited to: uploading the data through a 2G (second generation mobile communication technology) network, a 3G (third generation mobile communication technology) network, a 4G (fourth generation mobile communication technology) network, WIFI, Bluetooth and the like.

Since the geographical location of the mobile terminal may be constantly changing, the mobile terminal may upload its geographical location to the first server according to a preset frequency. For example, the mobile terminal uploads its geographical location to the first server every 5 seconds (other intervals such as 10 seconds are also possible). It should be noted that the identifier of the mobile terminal does not change in general, and therefore, the mobile terminal may upload the identifier of the mobile terminal to the first server once without uploading the identifier to the first server according to the preset frequency.

S103: and the first server compares the uploaded geographic position with the geographic fence to judge whether the mobile terminal is in the geographic fence or not.

A plurality of geofences can be maintained at the first server. After the first server acquires the geographic location uploaded by the mobile terminal, the geographic location can be compared with each geo-fence to determine whether the mobile terminal is inside the geo-fence. The mobile terminal may be inside one geofence or inside multiple geofences. The specific comparison procedure is as follows.

The first server may perform the same processing on the geographic location uploaded by the mobile terminal according to the tail-removing algorithm or the geohash algorithm in step S101. For example, in step S101, the first server performs geofence division on geographic locations within a preset range by using a tail-removing algorithm. In this step, the first server may also perform the same processing on the geographic location uploaded by the mobile terminal by using a tailing algorithm, so as to obtain a tailing longitude and latitude of the geographic location uploaded by the mobile terminal, and the tailing longitude and latitude may be used as a geographic location code of the geographic location uploaded by the mobile terminal.

After the first server uploads the geographic position of the mobile terminal to generate the geographic position code through the preset rule, the geographic position code can be compared with the stored geographic position code of the geographic fence. If the geographic position code is the same as that of a certain geographic fence, the mobile terminal can be known to be in the geographic fence. If the geographic position code is different from the geographic position code of the geofence stored by the first server, it can be determined that the mobile terminal is not inside the geofence stored by the first server.

S104: if the mobile terminal is inside the geo-fence, the first server determines a first electronic certificate corresponding to the mobile terminal identification and the geo-fence at the same time based on the identification uploaded by the mobile terminal and the corresponding relation between the geo-fence and the mobile terminal identification and the electronic certificate respectively.

The electronic certificate is generally an electronic certificate of a third party, and can also be acquired and stored by the mobile terminal. The number of the electronic certificates can be one or more.

In some embodiments, the first server obtains the geofence if the mobile terminal is inside the geofence. The number of geofences obtained by the first server may be one or more. And then, according to the corresponding relation between the geo-fence and the electronic certificate, the first server inquires the electronic certificate simultaneously corresponding to the geo-fence and the mobile terminal identification. The geo-fence and the mobile terminal identifier may correspond to one or more electronic certificates at the same time. For example, if the mobile terminal is identified as B, the third party is a merchant. When the mobile terminal is inside the geofence of merchant a, the first server may obtain the geofence of merchant a. And then the first server can acquire the electronic certificate of the merchant A according to the corresponding relation between the geographic fence of the merchant A and the electronic certificate of the merchant A. And finally, the first server can select the electronic certificate of the mobile terminal identifier B from the electronic certificates of the merchant A according to the corresponding relation between the mobile terminal identifier B and the electronic certificates. The first server can take the selected electronic certificate of the mobile terminal identification B as the currently effective electronic certificate.

For example, if the mobile terminal is identified as B, the third party is a merchant. When the mobile terminal is inside the geofence of merchant a, the first server may obtain the geofence of merchant a. Then, the first server can obtain the electronic certificate of the mobile terminal identification B according to the corresponding relation between the mobile terminal identification B and the electronic certificate. And finally, the first server can select the electronic certificate of the merchant A from the electronic certificates of the mobile terminal identifier B according to the corresponding relation between the geographic fence of the merchant A and the electronic certificates of the merchant A. The first server can use the selected electronic certificate of the merchant A as the first electronic certificate.

S105: and based on the electronic certificate corresponding to the mobile terminal identification and the geographic fence at the same time, the first server sends first information to the mobile terminal.

The first server can obtain the content of the first electronic certificate corresponding to the mobile terminal identification and the geo-fence at the same time, generate first information according to the content of the first electronic certificate, and send the first information to the mobile terminal. The first information includes content of the electronic voucher or other information.

For example, the first electronic voucher is a coupon, and the first information includes the time of use, the method of use, the password of use, and the like of the coupon.

For another example, the first electronic certificate is a train ticket, and then the first information includes the train departure time, a ticket checking window, and the like.

S106: the mobile terminal acquires the first information and prompts or displays the first information after acquiring the first information.

In some embodiments, after the mobile terminal acquires the first information sent by the first server, the first information may be displayed on a screen of the mobile terminal.

In another embodiment, after acquiring the first information sent by the first server, the mobile terminal may prompt the user for the first information, but does not display the first information on the screen. For example, after acquiring the first information sent by the first server, the mobile terminal prompts the first information to the user in a manner of ringing or vibrating.

The embodiment of fig. 1 corresponds to establishing a geofence for a third party. When the mobile terminal is in the geo-fence, the first server acquires the electronic certificate of the third party corresponding to the mobile terminal, so that information is sent to the mobile terminal to prompt the electronic certificate required by the user, and the user is prevented from searching the electronic certificate in the mobile terminal.

After a period of time elapses after the user acquires the electronic certificate of the third party, the user may forget the electronic certificate. In the embodiment corresponding to fig. 1, when the user arrives at the use or consumption area of the electronic certificate, the electronic certificate owned by the user is prompted by sending information to the mobile terminal of the user, so that the utilization rate of the electronic certificate is improved, and further, the transaction amount and the transaction amount of a third party are improved.

Meanwhile, the third party realizes the prompt of the electronic certificate by authorizing the first server (uploading the relevant information required by generating the electronic certificate to the first server). Therefore, the third party does not need to establish an electronic certificate prompting system, and resources are saved.

In another preferred embodiment, the first server may also send personalized information to the mobile terminal according to the needs of the third party. Specifically, as shown in fig. 3, this embodiment includes:

s301: the first server establishes the corresponding relation between the geo-fence and the electronic certificate, the mobile terminal identification and the electronic certificate, and the second server and the electronic certificate.

S305: based on the corresponding relation between the second server and the electronic certificate, the first server acquires the second server corresponding to the electronic certificate and requests the second server to acquire second information.

For example, the third party is merchant a, the first electronic certificate is the electronic certificate of merchant a, and the second server is the server of merchant a. Then, after the first server acquires the electronic certificate of the merchant A, the server of the merchant A is further acquired according to the electronic certificate of the merchant A.

In another embodiment, the first server establishes a correspondence between the mobile terminal identifier and the geo-fence, and after acquiring the identifier uploaded by the mobile terminal, the first server may first acquire the geo-fence according to the correspondence between the mobile terminal identifier and the geo-fence. The first server then compares the geographic location uploaded by the mobile terminal with the obtained geo-fence. This embodiment reduces the time required to determine whether a mobile terminal is inside a geofence, since there is no need to compare the geographic location uploaded by the mobile terminal to each geofence. Specifically, as shown in fig. 6, this embodiment includes:

s601: the first server establishes corresponding relations between the geo-fence and the electronic certificate, between the mobile terminal identification and the electronic certificate, and between the geo-fence and the mobile terminal identification.

in the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate a dedicated integrated circuit chip 2. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most popular applications. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory.

Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions.

For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functionality of the units may be implemented in one or more software and/or hardware when implementing the present application.

From the above description of the embodiments, it is clear to those skilled in the art that the present application can be implemented by software plus necessary general hardware platform. Based on such understanding, the technical solutions of the present application may be essentially or partially implemented in the form of a software product, which may be stored in a storage medium, such as a ROM/RAM, a magnetic disk, an optical disk, etc., and includes several instructions for enabling a computer device (which may be a personal computer, a server, or a network device, etc.) to execute the method according to the embodiments or some parts of the embodiments of the present application.

In particular, for the system embodiment, since it is substantially similar to the method embodiment, the description is simple, and for the relevant points, reference may be made to the partial description of the method embodiment.

The application is operational with numerous general purpose or special purpose computing system environments or configurations. For example: personal computers, server computers, hand-held or portable devices, tablet-type devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like.

The application may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The application may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.

While the present application has been described with examples, those of ordinary skill in the art will appreciate that there are numerous variations and permutations of the present application without departing from the spirit of the application, and it is intended that the appended claims encompass such variations and permutations without departing from the spirit of the application.
