Description

Method for determining hot IP address of terminal and terminal

Technical Field

The invention belongs to the technical field of wireless communication, and particularly relates to a method for determining a hotspot IP address of a terminal and the terminal.

Background

With the development of society and the progress of science and technology, intelligent terminals have the functions of network sharing and portable hot spots. Specifically, after the portable hotspot function is opened by the intelligent terminal, other terminals having a Wireless Local Area Network (WLAN) function access to the hotspot of the intelligent terminal, and the intelligent terminal shares its own data service to the other terminals that access.

At present, an intelligent terminal generates a hot spot IP address for hot spot service, and the hot spot IP address defaulted by a system is used as the hot spot IP address of the intelligent terminal. For example, the default hot IP address of the Android system is 192.168.43.1, and when the intelligent terminal is a terminal of the Android system, the intelligent terminal sets the hot IP address to be 192.168.43.1, and the hot IP address is fixed and unchangeable; the Dynamic Host Configuration Protocol (DHCP) range is 192.168.43.2-192.168.43.254; when other terminals access the hot spot of the intelligent terminal, the intelligent terminal allocates an IP address to the other terminals from the DHCP range.

In summary, the existing terminal can only adopt the default IP address of the system when generating the hot IP address, and this way of generating the hot IP address is not flexible enough.

Detailed Description

The terminal of the embodiment of the present invention may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or the like. The terminal provided by the embodiment of the invention has the functions of network sharing and portable hot spots.

The embodiment of the invention provides a method for determining a hot IP address of a terminal, wherein the terminal selects a first random number from a first preset range; the terminal determines that the selected first random number is used as a numerical value of a third section of the hot spot IP address; and the terminal generates a hot spot IP address according to the determined numerical value of the third section.

When determining the hot spot IP address, the terminal randomly selects a first random number from a first preset range, wherein the hot spot IP address comprises four sections, and the selected first random number is used as a numerical value of a third section in the hot spot IP address; and generating the hot spot IP address according to the numerical value of the third section. The embodiment of the invention combines the randomly selected numerical value with the preset rule, thereby flexibly generating the hot IP address of the terminal, avoiding using the default invariable hot IP address of the system and further improving the system performance of the terminal.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, 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 invention.

An embodiment of the present invention provides a method for determining a hot spot IP address of a terminal, as shown in fig. 1, where the method includes:

101, a terminal selects a first random number from a first preset range;

step 102, the terminal determines that the selected first random number is used as a numerical value of a third section of the hotspot IP address;

and 103, the terminal generates a hot spot IP address according to the determined numerical value of the third section.

In the embodiment of the present invention, the hot IP address has four segments, for example, the format is x.x.x.x, and the first segment, the second segment, the third segment, and the fourth segment are sequentially arranged from front to back.

It should be noted that, in an alternative provided by the embodiment of the present invention, the terminal selects the first random number from the first preset range, and uses the first random number as a numerical value of the third segment of the hotspot IP address, and the numerical values of other segments may use a numerical value in a default hotspot IP address configured by the system.

In addition, the embodiment of the invention also provides an alternative scheme, wherein the terminal selects a first random number from a first preset range; determining the selected first random number as a numerical value of a third section of the hot spot IP address; the terminal selects a second random number from a second preset range; and determining the selected second random number as the numerical value of the second section of the hot spot IP address.

In a second alternative, the terminal selects a first random number from a first preset range, selects a second random number from a second preset range, uses the first random number as a numerical value of a third section in the hot spot IP address, and uses the second random number as a numerical value of a second section in the hot spot IP address; the values of the other segments may use the values in the default hotspot IP address of the system configuration.

The two schemes are explained separately below.

One, selecting a random number

In this situation, the terminal selects a first random number from a first preset range, and the first random number is used as a numerical value of a third section of the hotspot IP address; and the terminal generates a hot spot IP address according to the determined numerical value of the third section.

Optionally, the preset range of the embodiment of the invention is 55-254;

the terminal selects a first random number from 55-254 and uses the selected first random number as the value of the third segment of the hotspot IP address.

The embodiment of the invention avoids the conflict between the hot IP address of the terminal and the Bluetooth IP address, the USB shared IP address and the like of the terminal, and sets the preset range to be 55-254.

For other segments except the third segment in the hot spot IP address, when the terminal generates the hot spot IP address, determining the numerical values of the other segments according to the following modes:

the terminal determines that a first preset value is used as a numerical value of a first section of the hot spot IP address, a second preset value is used as a numerical value of a second section of the hot spot IP address, and a third preset value is used as a numerical value of a fourth section of the hot spot IP address.

Optionally, the first preset value is 192, the second preset value is 168, and the third preset value is 1.

It should be noted that, the numerical values of the first segment and the second segment in the hot spot IP address adopt the default numerical values of the first segment and the second segment in the hot spot IP address, and only the numerical value of the third segment is randomly generated.

Then, assuming that the first random number selected by the terminal from the preset range is X, the determined hotspot IP address of the terminal is: 192.168. x.1; the DHCP range of the hotspot is: 192.168.X.2 ~ 192.168. X.254.

It should be noted here that since the IP address of 192.168.X.m is a private network address in a class C address, and the private network address is reserved in the IP protocol specification and is dedicated to a private network, using such an address as a hot spot IP address of a terminal can effectively avoid collision with other types of IP addresses.

In addition, an optional implementation manner is that after the hot spot IP address of the terminal is determined in the above manner, the terminal determines whether the hot spot IP address is the same as the WiFi IP address of the terminal, when the hot spot IP address is the same as the WiFi IP address of the terminal, the terminal reselects the first random number from the preset range, uses the selected first random number as the numerical value of the third segment of the hot spot IP address, and generates the hot spot IP address according to the newly determined numerical value of the third segment.

Therefore, the conflict between the WiFi IP address and the hot spot IP address of the terminal is further avoided.

The DHCP service is started at the beginning of the terminal system, namely, the DHCP service also needs to be started when the system of the terminal is started. The opening of the hot spot belongs to manual operation, and the hot spot is opened after receiving an operation instruction of a user.

The timing of determining the hot IP address of the terminal in the embodiment of the present invention may be:

the method comprises the steps that 1, after a terminal is started and before a DHCP service is started, a hot IP address of the terminal is determined;

and at the moment 2, after receiving an operation instruction of starting the hot spot of the user, determining the hot spot IP address of the terminal.

The following description will be made for different timings.

And aiming at the opportunity 1, after the hotspot IP address of the terminal is determined at the opportunity, determining a DHCP range corresponding to the hotspot IP address, setting the determined DHCP range into DHCP service, and starting the DHCP service. And when the hotspot IP address of the terminal is determined at the opportunity 1, the hotspot IP address of the terminal is determined once every time the terminal is started.

A complete flow chart for determining the hot spot IP address of the terminal according to the embodiment of the present invention is described below with reference to fig. 2.

Step 201, starting up a terminal;

step 202, before starting the DHCP service, the terminal selects a first random number X from a preset range;

wherein the preset range can be 55-254;

step 203, the terminal takes the selected first random number X as a numerical value of a third section in the hotspot IP address, and continues to use the numerical values of the first section and the second section in the hotspot IP address which is default by the system;

step 204, the terminal determines that the DHCP range of the hot spot is 192.168. X.2-192.168. X.254;

step 205, the terminal sets the determined DHCP range into DHCP service and starts the DHCP service;

step 206, the terminal determines a starting hotspot according to a user instruction;

and step 207, the terminal group hot spot IP address is 192.168.X.1, and the hot spot IP address of the terminal is set.

And for the opportunity 2, after receiving an operation instruction of starting the hotspot of the user, determining the hotspot IP address of the terminal, and because the DHCP range of the hotspot is set before the DHCP service is started, after determining the IP address of the hotspot, the terminal needs to update the DHCP range of the hotspot, set the DHCP range in the DHCP service, and restart the DHCP service. Therefore, when the terminal opens the hot spot each time, the IP address of the hot spot can be dynamically updated.

Specifically, the terminal 1 opens the hotspot, the terminal 2 accesses the hotspot of the terminal 1, and the terminal 1 shares the mobile data with the terminal 2 in a scene where the two terminals are connected through the hotspot. In this scenario, if the terminal 1 and the terminal 2 both use the existing default hot spot IP address of the system when determining the hot spot IP address, it is assumed that the hot spot IP address of the terminal 1 is 192.168.43.1 of the default system, and the hot spot DHCP range of the terminal 1 is 192.168.43.2-192.168.43.254. The terminal 1 randomly selects an address from the DHCP range 192.168.43.2-192.168.43.254 to allocate to the terminal 2 as a WiFiIP address of the terminal 2, and the terminal 2 establishes connection with a hot spot of the terminal 1 by using the IP address allocated by the terminal 1. For example, terminal 1 chooses 192.168.43.X as the WiFi IP address assigned to terminal 2, with X being any value between 2-254. If the hot spot of the terminal 2 is opened, the terminal 2 uses the hot spot IP address default by the system when setting the hot spot IP address, and the hot spot IP address of the terminal 2 is 192.168.43.1. For the terminal 2, the WiFi IP address and the hotspot IP address of the terminal 2 are both 192.168.43, so that two 192.168.43 network segments exist in the system and are respectively routed to the WiFi interface and the hotspot interface, which results in the collision between the WiFi IP address and the hotspot IP address of the terminal 2. When the terminal 2 accesses the external network, it cannot be determined which route is selected, so that the terminal 2 cannot surf the internet.

Based on the problem, the terminal 1 and the terminal 2 can adopt the mode of determining the hot spot IP address provided by the embodiment of the invention; or any one of the terminal 1 and the terminal 2 adopts the method for determining the hot spot IP address provided by the embodiment of the invention, and the other terminal continues to use the default hot spot IP address of the existing system, so that the problem that the WiFi IP address and the hot spot IP address of the terminal 2 conflict can be solved. The following description will be made by way of examples.

1. Only the terminal 2 uses the method for determining the hot spot IP address provided by the embodiment of the present invention.

As shown in fig. 3, the terminal 1 opens the hot spot sharing mobile data, and the terminal 1 generates a hot spot IP address (i.e., a system default hot spot IP address) of 192.168.43.1 in the existing manner, so that the hot spot DHCP range of the terminal 1 is 192.168.43.2-192.168.43.254.

The terminal 2 accesses a hotspot of the terminal 1 in a WiFi connection mode, and the WiFi IP address allocated to the terminal 2 by the terminal 1 is 192.168.43. X; when the terminal 2 determines the hot spot IP address, selecting a random number Y from a preset range (55-254), and taking the random number Y as the numerical value of the third section in the hot spot IP address, wherein the numerical values of the first section and the second section use the numerical values of the first section and the second section in the default IP address of the system, the hot spot IP address determined by the terminal 2 is 192.168.Y.1, and the hot spot DHCP range of the terminal 2 is 192.168. Y.2-192.168. Y.254.

Since the WiFi IP address of terminal 2 is 192.168.43.X, the hotspot IP address of terminal 2 is 192.168. Y.1; and Y is a numerical value between 55 and 254, so that the WiFi IP address and the hot spot IP address of the terminal 2 are different, and the problem that the WiFi IP address and the hot spot IP address of the terminal 2 conflict is solved.

It should be noted here that, when only the terminal 1 determines the hot spot IP address of the terminal by using the embodiment of the present invention, the problem that the WiFi IP address and the hot spot IP address of the terminal 2 conflict with each other can also be solved, which is the same as the principle of the method that only the terminal 2 determines the hot spot IP address of the terminal by using the embodiment of the present invention.

2. The terminal 1 and the terminal 2 both use the method for determining the hot spot IP address provided by the embodiment of the invention.

As shown in fig. 4, the terminal 1 opens the hot spot sharing mobile data, when determining the hot spot IP address, the terminal 1 selects a random number a from a preset range (55-254), and uses the random number a as the numerical value of the third segment in the hot spot IP address, the numerical values of the first segment and the second segment use the numerical values of the first segment and the second segment in the system default IP address, then the hot spot IP address determined by the terminal 1 is 192.168.a.1, and then the hot spot DHCP range of the terminal 1 is 192.168. a.2-192.168. a.254.

The terminal 2 accesses a hotspot of the terminal 1 in a WiFi connection mode, and the WiFi IP address allocated to the terminal 2 by the terminal 1 is 192.168. A.X; when the terminal 2 determines the hot spot IP address, a random number B is selected from a preset range (55-254), the random number B is used as a numerical value of a third section in the hot spot IP address, the numerical values of the first section and the second section use the numerical values of the first section and the second section in the default IP address of the system, the hot spot IP address determined by the terminal 2 is 192.168.B.1, and the hot spot DHCP range of the terminal 2 is 192.168. B.2-192.168. B.254.

The WiFi IP address of the terminal 2 is 192.168.A.X, and the hot spot IP address of the terminal 2 is 192.168. B.1; since a and B are random numbers arbitrarily selected from 55-254 and the probability that a and B are the same is 1/200, the probability of collision between the WiFi IP address and the hotspot IP address of the terminal 2 can be greatly reduced.

Two, choose two random numbers

In this case, the method for determining the hot spot IP address of the terminal is shown in the flowchart of fig. 5:

501, selecting a first random number from a first preset range and a second random number from a second preset range by a terminal;

step 502, taking the first random number as the numerical value of the third section of the hot spot IP address, and taking the second random number as the numerical value of the second section of the hot spot IP address;

and 503, the terminal generates a hotspot IP address according to the determined numerical value of the third section and the determined numerical value of the second section.

Optionally, the preset range of the embodiment of the present invention is 0 to 254;

the terminal selects the first random number and the second random number from 0 to 254, and takes the selected first random number as the value of the third segment of the hot IP address and the selected second random number as the value of the second segment of the hot IP address.

It should be noted that the first random number and the second random number selected from 0 to 254 by the terminal according to the embodiment of the present invention may be the same or different.

Aiming at other segments except the second segment and the third segment in the hotspot IP address, the terminal determines the numerical values of the other segments according to the following modes:

and the terminal determines to take the fourth preset value as the numerical value of the first section of the hot spot IP address and take the fifth preset value as the numerical value of the fourth section of the hot spot IP address.

Optionally, the fourth preset value is 10, and the fifth preset value is 1.

It should be noted that, since the value of the first segment in the hot spot IP address is 10, the hot spot IP address determined by the terminal is a private network address.

It should be noted that, because the private network address is reserved in the IP protocol specification and is dedicated to the private network, taking such an address as the hot IP address of the terminal can effectively avoid the conflict with other types of IP addresses.

Then, assuming that the terminal selects the first random number X and the second random number Y from the preset range, the determined hotspot IP address of the terminal is: and 10, Y.X.1, determining the hot spot IP address of the terminal as follows: 10, Y.X.2-10. Y.X.254.

In addition, an optional implementation manner is that after the hot spot IP address of the terminal is determined in the above manner, the terminal determines whether the hot spot IP address is the same as the WiFi IP address of the terminal, when the hot spot IP address is the same as the WiFi IP address of the terminal, the terminal reselects the first random number and the second random number from the preset range, uses the selected first random number as the value of the third segment of the hot spot IP address, uses the second random number as the value of the second segment of the hot spot IP address, and generates the hot spot IP address according to the newly determined value of the third segment and the value of the second segment.

It should be noted that, in the scheme of selecting two random numbers, two timings for determining the hot spot IP address of the terminal are the same as the above scheme of selecting one random number, and details are not described here.

A complete flow chart for determining a hot spot IP address of a terminal according to an embodiment of the present invention is described below with reference to fig. 6;

in fig. 6, the description will be given by taking an example in which the terminal determines the IP address of the hotspot after receiving the operation instruction of the user to start the hotspot.

601, the terminal receives an operation instruction of starting a hotspot of a user and starts the hotspot;

step 602, the terminal selects a first random number X and a second random number Y from a preset range;

wherein the predetermined range may be 0-254;

step 603, the terminal takes the selected first random number X as a numerical value of a third section in the hot spot IP address, takes the selected second random number Y as a numerical value of a second section in the hot spot IP address, takes a fourth preset value as a numerical value of the first section, and takes a fifth preset value as a numerical value of the fourth section;

the combined hot spot IP address is assumed to be 10. Y.X.1;

step 604, the terminal judges whether the hotspot IP address is the same as the WiFi IP address of the terminal, if yes, returns to step 602, and if not, executes step 605;

step 605, the terminal determines the DHCP range of the hotspot;

when the combined hot spot IP address is 10.Y.X.1, the DHCP range of the hot spot is 10. Y.X.2-10. Y.X.254;

step 606, the terminal restarts the DHCP service.

As shown in fig. 7, the terminal 1 opens the hot spot sharing mobile data, and the terminal 1 generates a hot spot IP address (i.e., a system default hot spot IP address) of 192.168.43.1 in the existing manner, so that the hot spot DHCP range of the terminal 1 is 192.168.43.2-192.168.43.254.

The terminal 2 accesses a hotspot of the terminal 1 in a WiFi connection mode, and the WiFi IP address allocated to the terminal 2 by the terminal 1 is 192.168.43. X; when the terminal 2 determines the hot spot IP address, two random numbers A, B are selected from a preset range (0-254), the random number A, B is used as the numerical values of the second segment and the third segment in the hot spot IP address, the numerical value of the first segment is set to 10, the hot spot IP address determined by the terminal 2 is 10.a.b.1, and the hot spot DHCP range of the terminal 2 is 10. a.b.2-10. a.b.254.

Since the WiFi IP address of the terminal 2 is 192.168.43.X, the hotspot IP address of the terminal 2 is 10. a.b.1; therefore, the WiFi IP address and the hotspot IP address of the terminal 2 are different, and the problem that the WiFi IP address and the hotspot IP address of the terminal 2 conflict is solved.

As shown in fig. 8, the terminal 1 opens a hot spot to share mobile data, when determining a hot spot IP address, the terminal 1 selects two random numbers A, B from a preset range (0-254), takes the random number A, B as numerical values of a second segment and a third segment in the hot spot IP address, sets the numerical value of the first segment to 10, and determines that the hot spot IP address determined by the terminal 1 is 10.a.b.1, and determines that a hot spot DHCP range of the terminal 1 is 10. a.b.2-10. a.b.254.

The terminal 2 accesses a hotspot of the terminal 1 in a WiFi connection mode, and a WiFi IP address allocated to the terminal 2 by the terminal 1 is 10. A.B.X; when the terminal 2 determines the hot spot IP address, two random numbers C, D are selected from a preset range (0-254), the random number C, D is used as the numerical values of the second section and the third section in the hot spot IP address, the numerical value of the first section is set to 10, the hot spot IP address determined by the terminal 2 is 10.c.d.1, and the hot spot DHCP range of the terminal 2 is 10. c.d.2-10. c.d 254.

The WiFi IP address of the terminal 2 is 10.A.B.X, and the hot spot IP address of the terminal 2 is 10. C.D.1; a, B, C, D are random numbers randomly selected from 0-254, A is the same as C, and B and D are the same with probability 1/65025, so that the probability of collision between the WiFi IP address and the hotspot IP address of the terminal 2 can be greatly reduced.

Based on the same inventive concept, the embodiment of the present invention further provides a terminal, and since the principle of solving the problem of the terminal is similar to the method for determining the hot IP address of the terminal in the embodiment of the present invention, the implementation of the terminal may refer to the implementation of the method, and repeated details are not repeated.
