Description

Method, device and equipment for acquiring IP address of group user

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a device for acquiring an IP address of a group user.

Background

The point-to-point wireless internet access (Wi-Fi Peer-to-Peer, Wi-Fi P2P) refers to supporting the wireless devices to connect with each other in a point-to-point manner in a wireless network without a router, so as to realize the communication between the devices.

In the existing Wi-Fi P2P connection scheme, after the device connection is successful, the role of the device is negotiated and allocated as a Group Client (GC) or a Group Owner (GO). A device in a group user role may directly acquire an Internet Protocol (IP) address of a group owner connected to the device; the device in the role of the group owner cannot directly acquire the IP of the group user connected to the device.

The method for acquiring the IP address of the group user in the related technology comprises the following steps:

(1) the proposed device is negotiated to assign a group user role by setting the proposed value when the device establishes a Wi-Fi P2P connection.

The method does not fundamentally solve the problem that the group user cannot acquire the IP of the group owner, and when the recommended values of the connected devices are the same, the roles of the group user and the group owner are random, so that the role of the device cannot be guaranteed to be the group user.

(2) When the device is allocated to the role of the group owner, a Socket is created and monitored, and when the group user is actively connected, the IP of the group user is obtained through a Socket.

The method for acquiring the group user IP needs to create additional communication service and establish a monitoring port, passively relies on the group user to actively establish connection, and cannot acquire the group user IP when the group owner actively connects the group user.

A method, an apparatus, and a device for acquiring an IP address of a group user in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Example 1

As shown in fig. 1, an embodiment of the present invention provides a schematic diagram of an application scenario for acquiring IP addresses of group users, where the application scenario includes:

a group owner GO device 101 for allocating an internet protocol IP address to at least one group user through a dynamic host configuration protocol DHCP service process; acquiring the allocated IP address through the DHCP service process, and storing the IP address to a local file; determining a group user to be connected, and reading the IP address of the group user in the local file;

a group user GC device 102, configured to establish a connection with the group owner GO device, and receive an IP address assigned by the group owner GO device.

It should be noted that the schematic diagram of the application scenario shown in fig. 1 is only an example provided by the embodiment of the present invention, and does not limit the embodiment of the present invention at all, and in the specific implementation, the addition or deletion of the entity device may be performed according to the specific implementation situation. For example, the group owner GO device may establish a one-to-one connection with a group user GC device in the application scenario, where only one group user GC device 102 exists in the application scenario; the group owner GO device may establish connections with multiple group user GC devices, where multiple group user GC devices 102 exist in the application scenario.

It should be noted that, in the scenario of Wi-Fi P2P connection, only one group owner GO device exists among the devices connected to each other.

The group owner and the group user refer to the roles played by the devices in the Wi-Fi P2P connection, and do not limit the implementation functions of the devices, and the group owner GO device and the group user GC device may be any physical devices with networking functions. Such as smart terminals, smart appliances, smart home devices, etc.

As an optional implementation manner, the application scenario is a multi-screen interaction scenario between the intelligent terminal and the intelligent television device.

An embodiment of the present invention provides a flowchart of a method for a group owner GO device to obtain an IP address of a group user, as shown in fig. 2, including:

step S201, an internet protocol IP address is distributed to at least one group user through a dynamic host configuration protocol DHCP service process;

before the above IP address allocated to at least one group user through the DHCP service process, the method further includes:

1. selecting a device to establish a Wi-Fi P2P connection:

embodiment 1: actively look for Wi-Fi P2P enabled devices.

(1) Searching for equipment supporting point-to-point wireless internet Wi-Fi P2P;

device Discovery phase Device Discovery: and finding out devices which are within a certain range and support Wi-Fi P2P through the Wi-Fi P2P.

The number of the searched devices supporting Wi-Fi P2P may be one or more, and the situation that no device supporting Wi-Fi P2P exists may occur.

When the device supporting the Wi-Fi P2P is not found, the finding is continued, and when the finding time is larger than a preset threshold value, a prompt of finding failure is sent.

(2) Selecting at least one group user for establishing connection in the searched equipment;

device Selection phase Device Selection: after the device A finds the device B, the device A sends prompt information to the user so that the user can select whether to be paired with the device B according to requirements.

When the number of the searched devices supporting Wi-Fi P2P is one, sending prompt information to a user so that the user can select whether to pair with the searched device supporting Wi-Fi P2P according to requirements;

when the number of the searched devices supporting Wi-Fi P2P is multiple, prompt information is sent to the user, so that the user can select whether to pair with the searched devices supporting Wi-Fi P2P and which devices are paired according to requirements.

Embodiment 2: waiting for a connection request by a device that supports Wi-Fi P2P.

The group user searches for devices supporting point-to-point wireless internet Wi-Fi P2P, and selects a group owner GO device for establishing connection from the searched devices.

A group owner GO device receives a request sent by at least one group user to establish a connection.

2. Establishing a connection with the at least one group user via Wi-Fi P2P protocol.

And establishing the connection between the devices according to the Wi-Fi Direct technical specification.

The connection establishment phase also comprises the allocation of roles among the devices, wherein the roles comprise a Group Owner and at least one Group user Group Client.

Note that, in the device that selects to establish the Wi-Fi P2P connection in step 1, no role has been assigned yet, and the description is made from the perspective of the device assigned as the group owner GO device in step 2.

The above process can also be explained by the following way:

the first device searches for a device supporting Wi-Fi P2P through Wi-Fi P2P;

the first equipment selects at least one second equipment for establishing connection from the searched equipment;

establishing a connection between the first device and a second device via Wi-Fi P2P, and determining roles for the first device and the second device, the roles including a group owner and at least one group user.

The first device and the second device may be in a role of a group owner or a group user.

When the first device is in the role of a group user, the number of the second devices is 1.

After the group owner GO equipment is determined, the group owner GO equipment is used as a DHCP Server, the group user GC equipment is used as a DHCP Client, an IP address is distributed to the group user GC equipment through the group owner GO equipment through a DHCP protocol, and the function of a DHCP service process is realized by using DNSmasq in an Android system. The specific steps of the DNSmasq work are as follows:

as shown in fig. 3, an embodiment of the present invention provides a flowchart of a method for allocating an IP address to a group user through a DHCP service process, where the method includes:

step S301, receiving DHCP discovery data broadcasted by at least one group user in a local area network;

the group user GC device initiates a DHCP discover packet, i.e. the above DHCP DISCOVERY data, in the local area network, in order to discover a DHCP Server capable of providing an IP.

And the group owner GO equipment receives the DHCP discover packet initiated by the at least one group user GC equipment.

Step S302, sending DHCP suggestion data to the at least one group user, wherein the suggestion data comprises IP addresses suggested to be adopted;

after receiving the DHCP discover packet, the available DHCP Server sends a DHCP OFFER packet, that is, the DHCP advice data, and gives a response to the DHCP Client, thereby notifying the DHCP Client that an IP address can be provided.

The format of the IP address carried in the DHCP offer data may be "IP address: 192.168.3.1".

Step S303, receiving DHCP request data for confirming to adopt the IP address sent by the at least one group user, wherein the DHCP request data comprises a Media Access Control (MAC) address of a corresponding group user;

after receiving the DHCP OFFER packet, the DHCP Client sends a DHCP REQUEST packet, i.e., the DHCP REQUEST data, requesting allocation of an IP address.

And the DHCP Server receives a DHCP REQUEST packet sent by the at least one DHCP Client, wherein the DHCP REQUEST packet comprises the MAC address of the DHCP Client.

The format of the MAC address carried in the DHCP request data may be "MAC address: 8e aa 37:09:19:8d ".

Step S304, sending DHCP response data to the at least one group user, indicating that the IP address allocation of the corresponding group user is completed.

The DHCP Server sends DHCP ACK data packet, namely DHCP response data and confirmation information.

Step S202, acquiring the allocated IP address through the DHCP service process, and storing the IP address to a local file;

an existing DHCP service process does not have a function of storing an IP address to a local file, and therefore, before the DHCP service process acquires an allocated IP address and stores the IP address to a local file, the DNSmasq is modified to have a function of storing an IP address to a local file, where the modification method includes:

acquiring an original DHCP service process for allocating an IP address;

It should be noted that the above operation of modifying the DHCP service process may be performed by the node at any time before the IP address is stored in the local file.

After the DHCP ACK packet is sent, acquiring an allocated IP address through the DHCP service process, and storing the IP address to a local file, including:

It should be noted that, the local file stores an IP address of at least one group user, the IP address is associated with a MAC address of a corresponding group user, the associated MAC address is used for distinguishing, and the associated MAC address is used as an identifier of the query.

The format of the IP address and the associated MAC address may be "MAC address 1: 8e aa:37:09:19:8 d; IP address 1:192.168.3.1 ".

It should be noted that the local file includes at least one of the following:

a system attribute of the group owner;

storing a file at an IP address created in the file list of the group owner.

As an alternative embodiment, the system attribute is dhcp.

Step S203, determining a group user to be connected, and reading an IP address of the group user in the local file.

When the group owner GO device needs to actively connect to the group user GC device, the IP allocated by the group owner GO device for the group user GC device may be read from a local file, for example, a system attribute dhcp.

And after the group owner GO device acquires the IP address of the group user GC device, establishing RTSP connection with the group user GC device through the IP address.

Taking a one-to-one connection between a group owner GO device and a group user GC device as an example, as shown in fig. 4, an embodiment of the present invention provides an interactive flowchart of a method for acquiring an IP address of a group user, including:

step S401, the device A searches for a device supporting Wi-Fi P2P within a certain range through Wi-Fi P2P;

the step S401 is a Device Discovery phase.

Step S402, after the device A finds the device B, the device A sends prompt information to a user so that the user can select whether to pair with the device B according to requirements, if yes, the step S403 is executed, and if not, the step S401 is executed;

the step S402 selects the phase Device Selection for the Device.

Step S403, establishing connection between the equipment A and the equipment B according to the Wi-Fi Direct technical specification;

step S404, the device a and the device B perform role negotiation to determine roles of a group owner GO device and a group user GC device.

In this embodiment, the device a is determined to be a group user GC device, and the device B is determined to be a group owner GO device.

Step S405, the group owner GO device distributes an IP address for the group user GC device through a DHCP service process, and writes the IP address into the attribute of the android system after sending a DHCP ACK data packet;

as shown in fig. 5, an interactive schematic diagram of group owner GO device assignment and IP address storage is provided in an embodiment of the present invention.

1. The GC equipment of the group user initiates a DHCP discover packet in the local area network;

and the group owner GO equipment receives the DHCP discover packet initiated by the group user GC equipment.

2. The group owner GO equipment sends a DHCP OFFER packet to inform the group user GC equipment that an IP address can be provided;

3. after receiving the DHCP OFFER packet, the group user GC equipment sends a DHCP REQUEST packet to REQUEST for IP allocation;

4. and the group owner GO equipment sends a DHCP ACK data packet and confirms information.

And after the DHCP ACK data packet is sent, writing the IP address into the attribute of the android system.

Step S406, reading the android system attribute by the group owner GO device, acquiring the IP address of the GC device of the opposite end group user, and establishing RTSP connection.

The above steps S403 to S406 are Connection Setup phases.

Step S407, after the RTSP connection is established, the group owner GO device and the group user GC device perform capability negotiation.

The step S407 is a Capability Negotiation stage.

The above step S407 and the subsequent communication process between the group owner GO device and the group user GC device are not the key contents of the present invention, and the existing scheme may be applied to this step, and will not be described herein again.
