Specific embodiments of the present application have been shown by way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.

When an IP address needs to be allocated to a communication device in the prior art, firstly, the communication device sends a configuration request message containing an initial IP address of the communication device of 0.0.0.0 to a target access device, after the target access device receives the configuration request message, the configuration request message containing a preset IP address of the communication device is generated, and then the configuration request message is sent to the communication device, at this time, the communication device determines the preset IP address corresponding to the target access device according to the configuration request message containing the preset IP address of the communication device, and generates a configuration response message, and sends the configuration response message to the target access device, so that the target access device allocates an IP address to the communication device, and generates a configuration partial response message, wherein the configuration partial response message contains the allocated target IP address, so that the communication device determines the allocated IP address according to the configuration partial response message, and generates a configuration grant request message, so that the communication device initiates a configuration grant request message using the target IP address to the target access device, and then the target access device determines the allocated IP address of the communication device, and sends the configuration grant response message to the communication device, so that the communication device confirms that the target access device uses the allocated address to realize data transmission.

However, when the communication device is allocated with an IP address in the prior art, multiple interactions between the communication device and the target access device are required, and since a link is established between one target access device and multiple communication devices, the process of allocating the IP address increases the consumption of the overall network, and wastes network resources.

In order to solve the defects of the prior art, the inventor of the scheme designs a new scheme through creative research. In order to solve the problems that the whole network consumption is increased and network resources are wasted in the course of distributing IP addresses, after a target access device generates a distribution request, the target access device determines that a target link is established with target communication devices based on the distribution request, so that the target IP addresses are distributed to the target communication devices, a configuration request message is generated, the configuration request message is sent to the target communication devices to instruct the target communication devices to determine and use the target IP addresses according to the configuration request message, and further the target communication devices generate a configuration response message which comprises stop message interaction instruction information, so that the target access device controls itself not to send the IP address distribution message to the target communication devices according to the stop message interaction instruction information, and the target communication devices and the target access device only interact once, so that the target IP addresses are distributed to the target communication devices.

The application provides an Internet protocol address allocation method, an Internet protocol address allocation device, internet protocol address allocation equipment and an application scene of a storage medium.

Fig. 1 is an application scenario diagram of an internet protocol address allocation method provided by the present application. As shown in fig. 1, the application scenario diagram includes a target access device 101 and a target communication device 102.

Wherein a link may be established between the target access device 101 and the target communication device 102. Wherein the target access device 101 comprises means for assigning internet protocol addresses.

The target communication device 102 may be any communication device, such as a cell phone or a computer, without limitation.

Specifically, when the target access device 101 determines that the internet protocol IP address allocation request generation condition is satisfied, the target access device 101 generates an IP address allocation request, then allocates a target IP address to the target communication device after determining to establish a target link with the target communication device 102 based on the allocation request, generates a configuration request message based on the allocated target IP address, and transmits the configuration request message to the target communication device 102.

Further, the target communication device 102 receives the configuration request message, and determines and uses the target IP address according to the configuration request message.

Further, the target communication device 102 generates a configuration response message, where the configuration response message is generated based on the target link, the target IP address, and the preset stop message interaction indication information. The target communication device 102 sends a configuration response message to the target access device 101.

Further, the target access device 101 receives the configuration response message, and controls not to send a message about IP address allocation to the target communication device according to the stop message interaction indication information. At the same time, the target access device 101 determines that the target communication device 102 accesses the network using the target IP address and performs data transmission over the target link.

It should be noted that, the message about IP address allocation may refer to a configuration confirmation response message in the prior art, so in the present application, after receiving the configuration response message sent by the target communication device, the target access device 101 may know that the target communication device determines and uses the target IP address, so the target access device 101 chooses not to continue sending the message about IP address allocation to the target communication device, where the message about IP address allocation may be the configuration confirmation response message, and interaction between the two devices may be reduced. And when the target communication equipment receives the configuration request message, the target communication equipment can confirm and use the target IP address, so after the whole process of distributing the target IP address is completed, when the target communication equipment needs to send data to the target access equipment, the target communication equipment can directly access the network through the target IP address, and further data transmission is realized.

It should be noted that, the user information (including but not limited to user equipment information, user personal information, etc.) and the data (including but not limited to data for analysis, stored data, presented data, etc.) related to the present application are information and data authorized by the user or fully authorized by each party, and the collection, use and processing of the related data need to comply with related laws and regulations and standards, and provide corresponding operation entries for the user to select authorization or rejection.

Fig. 2 is a block diagram of an internet protocol address allocation system according to the present application. As shown in fig. 2, includes a target communication device 201 and a target access device 202.

It should be noted that the principle of implementing data transmission by two target communication devices is described below. Assuming that the target communication device 201 corresponds to the target access device 202, the other target communication device a corresponds to the other target access device a, if it is desired to achieve transmission of data from the target communication device 201 to the target communication device a, it is actually the data that is sent from the target communication device 201 to the corresponding target access device 202, then the data is sent by the target access device 202 to the target access device a, and then the target access device a sends the data to the target communication device a, thereby achieving transmission of the data between the two communication devices.

It will be appreciated that there is an established link between the target communication device 201 and the target access device 202, and that a network is also required if data transfer is to be effected. And the target communication device 201 and the target access device 202 need to have legitimate IP addresses to access the network, so that the transfer of data between the target communication device 201 and the target access device 202 is achieved based on the network and the link.

It should be noted that, the PPPoE protocol includes two phases, namely a discovery phase and a session phase, and in the present application, the interaction flow is mainly simplified for the session phase, where the discovery phase refers to that a suitable access device is discovered for a target communication device as a target access device, so that a target link can be established between the target communication device and the target access device. The session stage includes two protocols, namely a link control protocol (Link Control Protocol, abbreviated as LCP) and a network control protocol (Network Control Protocol, abbreviated as NCP), wherein the present application mainly performs network control protocol after performing link control protocol authentication, and it can be understood that the present application simplifies the flow of the network control protocol.

As shown in fig. 2, in the present application, a configuration request message is sent to a target communication device 201 by a target access device 202, where the configuration request message includes a target IP address allocated to the target communication device 201 and a preset IP address, where the preset IP address is an IP address corresponding to the target access device 202.

Further, the target communication device 201 determines and uses the target IP address, and simultaneously generates and transmits a configuration response message to the target access device 202, so that the target access device 202 determines that the target communication device 201 accesses the network using the target IP address.

It will be appreciated that both the target IP address and the preset IP address have access to the network, so that the target communication device 201 accesses the network by using the target IP address, and the target access device 202 accesses the network by using the preset IP address, thereby implementing data transmission between the target links under the action of the network. Where the target link refers to an established link between the target communication device 201 and the target access device 202.

It should be noted that, in the present application, the message may further include a session identifier corresponding to the target link created in the discovery stage and a media access control address (Media Access Control Address, abbreviated as MAC) corresponding to each device, or other information, which is not limited herein.

It should be noted that, after the assignment of the target IP address to the target communication device is implemented, a handshake operation may be set periodically.

The application provides an internet protocol address allocation method, which aims to solve the technical problems in the prior art.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Example 1

The present application performs allocation means (hereinafter referred to as allocation means) of which the subject is an internet protocol address, the allocation means being located in a target access device. The method is applied to the target access equipment.

The target access device may be a broadband access server (Broadband Remote Access Server, abbreviated as BRAS) which is a novel access gateway for broadband network application, and refers to a network device for managing and controlling bandwidth access users, and may also be referred to as a broadband remote access server.

Fig. 3 is a flowchart of an internet protocol address allocation method according to a first embodiment. As shown in fig. 3, the specific steps are as follows.

S301, in response to the internet protocol IP address allocation request generation condition being satisfied, generates an IP address allocation request.

Wherein, the IP address allocation request refers to a request for allocation of an IP address.

In one mode, the allocation user triggers the IP address allocation component through the target access device, so that the target access device determines that the IP address allocation request generation condition is met, and then generates the IP address allocation request.

In one way, the target access device itself determines that the PPPoE protocol has completed the first discovery phase, i.e. the IP address allocation request generation condition is met on behalf of the target access device, so that the target access device generates an IP address allocation request, so that the target access device will enter the session phase in the PPPoE protocol.

S302, after the establishment of the target link with the target communication equipment is determined based on the allocation request, the target IP address is allocated to the target communication equipment.

The target IP address refers to an available, legal and secure IP address allocated to the target communication device. It should be noted that any communication or network device needs an IP address to realize data transmission, so in this step, a target IP address is first allocated to a target communication device for realizing access to a network, so that data transmission is realized by means of the network.

In one mode, the target access device performs determination of the target link based on the allocation request, and if it is determined that the target link is established, the target access device starts to select one IP address from the at least one IP address as the target IP address.

Wherein, the target link refers to a link established between the target communication device and the target access device.

S303, generating a configuration request message based on the target IP address; the configuration request message includes a target IP address allocated for the target communication device.

Further, the target access device loads the allocated IP address into the configuration request message, so that the configuration request message is generated based on the target IP address.

It should be noted that, the configuration request message in the present application may further include preset IP addresses or other information corresponding to other target access devices, which is not limited herein.

S304, sending the configuration request message to target communication equipment to instruct the target communication equipment to determine and use a target IP address based on the configuration request message, and generating a configuration response message based on a target link, the target IP address and preset stop message interaction instruction information; and stopping the message interaction indicating information to control the target access equipment not to feed back the indicating information about the IP address allocation message.

Further, the configuration request message is sent to the target communication device, and then the target communication device determines and uses the target IP base, and further, the target communication device generates a configuration response message based on the target link, the target IP address and the preset stop message interaction indication information.

The preset stop message interaction indication information can be a field in the configuration response message and is used for indicating that the target access device does not feed back the message about IP address allocation in the process of allocating the target IP address of the current allocation request, so that the target access device does not send other messages about IP address allocation to the target communication device after receiving the configuration response message based on the stop message interaction information, thereby being capable of reducing interaction between the two devices. Wherein, the two devices refer to a target communication device and a target access device.

The configuration response message includes the target IP address and the rest information.

S305, in response to receiving the configuration response message sent by the target communication device, controlling not to send a message about IP address allocation to the target communication device according to the stop message interaction indication information, determining that the target communication device uses the target IP address to access the network based on the target IP address, and carrying out data transmission through the target link.

In one manner, the target access device receives the configuration response message and reads the relevant stop field in the stop message interaction indication information, so that the target access device will control itself not to send a message about IP address allocation to the target communication device.

It can be understood that, under the current allocation request, the target access device controls not to send a message about IP address allocation to the target communication device according to the stop message interaction indication information, but still normally continues to allocate the target IP address under the next allocation request.

Further, after receiving the configuration response message, the target access device reads the target IP address included in the configuration response message, so that the target access device determines that the target communication device agrees to use the target IP address to access the network, and performs data transmission through the target link.

The embodiment provides an allocation method of internet protocol addresses, in the application, target access equipment firstly generates an IP address allocation request, determines to establish a complete target link with target communication equipment based on the allocation request, and further allocates target IP addresses for the target communication equipment, wherein the target IP addresses can be used for realizing access to a network, thereby realizing data transmission between the target communication equipment and the target access equipment, specifically, the target access equipment actively generates a configuration request message, sends the configuration request message to the target communication equipment, the configuration request message comprises the target IP address allocated to the target communication equipment, thereby indicating the target communication equipment to determine and use the target IP address based on the configuration request message, further, the target communication equipment is indicated to generate a configuration response message based on the target link, the target IP address and preset stop message interaction indication information, wherein the stop message interaction indication information is the indication information for controlling the target access equipment to not feed back the indication information about the IP address allocation any more, so that the target access equipment can control itself to continue sending the information about IP address allocation to the target communication equipment according to the stop message interaction indication information after the configuration response message is received by the target access equipment, thereby realizing that the configuration of the target access equipment is not required to be interacted with the target communication equipment for realizing the allocation of the target communication equipment for a plurality of times when the configuration request is initiated by the target access equipment, therefore, the target IP address can be obtained when the target communication device receives the message sent by the target access device for the first time, and after the target communication device also confirms and uses the target IP address, the target access device does not need to continuously send the message about IP address allocation to the target communication device, so that the target communication device confirms that the target access device knows that the target access device determines and uses the target IP address, network overhead is reduced, and network resources are saved.

Example two

This embodiment is a further refinement of any of the embodiments described above in that the step of determining a target link with the target communication device based on the allocation request is an alternative.

Fig. 4 is a flowchart of an internet protocol address allocation method according to a second embodiment. As shown in fig. 4, the specific steps are as follows.

S401, performing target link control protocol authentication based on the allocation request; the target link control protocol is a link control protocol between the target access device and the target communication device.

In PPP communication, a transmitting end and a receiving end determine necessary information in a data transmission process by transmitting a link control protocol LCP packet. The LCP packet, among other things, checks whether the link is well connected and whether the link is capable of supporting data transmission at the expected transmission speed.

The target access device starts to perform target link control protocol authentication for the link between the target access device and the target communication device based on the allocation request.

S402, generating a target link control protocol authentication passing result in response to detecting that the target link is established with the target communication device when the target link control protocol authentication is executed. Specifically, when the target link control protocol is executed, the target access device determines that a target link is established with the target communication device, and if the connection is complete, the target link control protocol authentication is determined to pass, and then a target link control protocol authentication passing result is generated.

The checking of the target link in this step further includes determining whether the link can support the expected transmission speed, and if so, the authentication is passed.

S403, determining that the target link is established with the target communication equipment based on the authentication passing result.

Further, the target access device determines that the target access device establishes a target link with the target communication device based on the authentication passing result.

The present embodiment provides a method for allocating an internet protocol address, in this embodiment, a target access device first performs target link control protocol authentication, and after performing the target link control protocol authentication, it is checked that a target link is established with a target communication device, so that an authentication passing result can be generated, so that in this embodiment, it can be accurately determined that the target link is established with the target communication device based on the target link control protocol.

Example III

This embodiment is a further refinement of any of the embodiments described above in that it is an alternative way of assigning a target IP address to a target communication device.

Fig. 5 is a flow chart of an internet protocol address allocation method according to the third embodiment. As shown in fig. 5, the specific steps are as follows.

S501, acquiring a preset IP address set; the preset IP address set comprises at least one IP address; at least one IP address included in the preset IP address set has the authority to access the network.

The preset IP address set comprises at least one IP address, and the at least one IP address is an available, legal and safe IP address, so that the at least one IP address has the authority to access the network.

The preset IP address set may be stored in the target access device in advance, or may be stored in a database independent of the target access device.

In one mode, after the establishment of the target link with the target communication device is determined, a preset IP address set is acquired in a storage area of the target communication device.

S502, searching an unassigned IP address in at least one IP address.

It should be noted that, at least one IP address in the preset IP address set, where each IP address has a respective corresponding state, the states of the IP addresses may include an "allocated state" and an "unallocated state", where some IP addresses may have been allocated so as to be in an "allocated state", and some IP addresses may have been in an unallocated idle state so as to be in an "unallocated state".

Specifically, the target access device searches for the state of each IP address in at least one IP address, determines that one state is an "unassigned state", and determines the IP address corresponding to the "unassigned state" as an unassigned IP address.

It should be noted that, at least one IP address in the preset IP address set may be stored sequentially, when the target access device searches in the at least one IP address, it may search in sequence, and when the state of the first IP address is found to be "unassigned state" according to the sequence, it is determined that the IP address corresponding to the first "unassigned state" is the unassigned IP address.

S503, determining the unassigned IP address as the assigned target IP address of the target communication device.

Further, the unassigned IP address is determined to be the target IP address.

The present embodiment provides a method for allocating an IP address, in this embodiment, a preset IP address set is first obtained, and an unallocated IP address is searched for from at least one IP address, so that in this embodiment, an unallocated IP address can be accurately found, and the unallocated IP address is never determined as a target IP address.

Example IV

This embodiment is a further refinement of any of the embodiments described above in that the determination of the destination communication device to access the network using the destination IP address is based on the destination IP address, and an alternative way of data transmission over the destination link.

Fig. 6 is a flowchart of an internet protocol address allocation method according to a fourth embodiment. As shown in fig. 6, the specific steps are as follows.

S601, obtaining the target IP address and the session identifier corresponding to the target link from the configuration response message.

In this embodiment, the configuration response message includes a target IP address and a session identifier corresponding to the target link, where the session identifier is created by the target access device in the discovery stage and is used to refer to the identifier of the target link.

In one manner, after receiving the configuration response message and reading the target IP address, the target access device determines that the target communication device agrees to use the target IP address to access the network according to the target IP address.

In practical application, the target IP address and the session identifier need to be bound, so as to realize a one-to-one correspondence. For example, if the target IP address of the target communication device is the first IP address and the session identifier corresponding to the target link between the target communication device and the target access device is the first session identifier, the first IP address is bound to the first session identifier, and the first IP address cannot be bound to the remaining session identifiers. It can be appreciated that, for the first session, a corresponding target link is identified, and the corresponding target communication device can only access the network using the first IP address in the current state, and realize data transmission through the target link.

And in response to any target data to be transmitted from the target access device to the target communication device, acquiring session information from the session database and carrying the session information into the target data.

For example, assuming that any target data is "weather today is good", when the target data is transmitted from the target access device to the target communication device, the target access device acquires session information corresponding to the target communication device from the session data, and then carries the session information into the target data. The session information is assumed to be a first IP address and a first session identification.

Transmitting target data carrying session information to target communication equipment by accessing a network by using a preset IP address and a target link so as to instruct the target communication equipment to access the network by using the target IP address when replying to the target data, transmitting the replied data to target access equipment based on the network and the target link so as to perform data transmission, and instructing the target communication equipment to determine whether the target data is safe or not according to the session information; the preset IP address is the IP address with the access network authority corresponding to the target access equipment.

The target access device accesses the network by using the preset IP address, and transmits target data carrying session information to the target communication device through the target link with the help of the network, so as to instruct the target communication device to access the network by using the target IP address when replying to the target data, which may be "good today, and transmit reply data to the target access device through the target link, wherein the reply data is a reply to the target data. Therefore, data transmission is realized according to the session information, the network and the target link.

In addition, when the target communication device receives the target data carrying the session information, whether the target data is safe or not can be determined through the session information. The target communication device determines, for example, a target IP address and a session identifier in session information, then matches the target IP address and a session identifier corresponding to a target link that are determined and agreed to be used by the target communication device, and if the target IP address stored by the target communication device is also a first IP address and the session identifier is also a first session identifier, determines that the first IP address and the first session identifier in the session information are matched, thereby determining that the target data is safe. If not, it is unsafe.

It should be noted that, when the target access device receives the reply data, the reply data also carries the target IP address and the session identifier, so that when the target access device receives the reply data, it can also determine whether the reply data is safe according to the carried target IP address and the session identifier, which is not described herein.

In this embodiment, in response to any target data needing to be sent from the target access device to the target communication device, the target access device carries session information into the target data, accesses the network by using a preset IP address, and further instructs the target communication device to transmit the reply data to the target access device by using the target IP address to access the network and the target link by using the target link to realize data transmission through the network.

And responding to the condition that the configuration response message sent by the target communication equipment is not received within the preset waiting time, and continuing to send the configuration request message to the target communication equipment.

The preset waiting time is the time for the target access device to wait for the target communication device to send the configuration response message. By way of example, and not limitation, may be 2 minutes or the like.

The target access device starts to wait to receive the configuration response message sent by the target communication device after sending the configuration request message to the target communication device, and if the target access device waits for a preset waiting time period (2 minutes is assumed), the target access device does not receive the configuration response message within the preset waiting time period, and continues to send the configuration request message to the target communication device, and then continues to wait.

And re-initiating an allocation request in response to the fact that the configuration response message sent by the target communication equipment is not received within the preset waiting time of continuing waiting.

Specifically, the target access device continues to wait for a preset waiting duration, and still does not receive the configuration response message sent by the target communication device within the preset waiting duration of the continuous waiting, so that the target access device reinitiates the allocation request.

The embodiment provides an internet protocol address allocation method, in this embodiment, corresponding measures are respectively made for the condition that no configuration response message is received in a preset waiting time period and a preset waiting time period of continuous waiting, so that a target communication device is stimulated to send the configuration response message.

The active discovery termination message (PPPoE Active Discovery Terminate, abbreviated as PADT) is a message for terminating a PPP session, and may terminate a session between a target communication device and a target access device. The PPP session refers to data transmission implemented under PPPoE protocol.

The generation condition is that no data is transmitted between target links through a network within a preset idle time, wherein the preset idle time refers to a preset quiet time between two devices, namely, no data is transmitted between the target communication device and the target access device at the moment. By way of example, the preset idle period may be 30 minutes or one hour, without limitation.

In one manner, the generation condition may be that the target access device and/or the target communication device leave the coverage area of the network, so that the target access device and/or the target communication device cannot use the network to perform data transmission, and the target communication device may generate the active discovery termination message.

In one approach, the active discovery termination message may also be generated by the target access device.

The session information is deleted in the session database to sever the target link and stop accessing the network using the target IP address.

Specifically, the target access device deletes the session information corresponding to the target communication device from the session database, thereby cutting off the target link with the target communication device, and further stopping the target communication device from accessing the network using the target IP address.

The embodiment provides an internet protocol address allocation method, in this embodiment, aiming at the phenomenon that no data is transmitted in a target link in a preset idle time, a target communication device generates an active discovery termination message, so that a target access device can delete a new session, cut off the target link, and stop using a target IP address to access a network, thereby releasing the target IP address and a session identifier, so that resources can be released, and the link establishment with a subsequent communication device and the data transmission using the network are facilitated.
