Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to an address allocation method, apparatus and storage medium. Background Technology

[0002] Currently, Broadband Remote Access Servers (BRAS) employ a dynamic Internet Protocol (IP) address allocation mechanism. When an end user sends a disconnect request to the BRAS device and breaks the connection, and then sends a reconnection request, the BRAS device dynamically selects an IP address randomly from its IP address pool and assigns it to the end user. This results in the end user receiving a different IP address than the one obtained previously. Therefore, how to assign a fixed IP address to the end user based on their needs has become a pressing technical problem. Summary of the Invention

[0030] The technical solution provided in this disclosure offers at least the following advantages: A terminal sends an online message to a Broadband Access Server (BRAS) to obtain an IP address and request access to the BRAS device. Upon receiving the online message from the terminal, the BRAS device determines, based on the terminal's identifier contained in the online message, whether the first IP address allocated to the terminal during its last online session exists in the set of addresses to be allocated. If the first IP address exists in the set of addresses to be allocated, the BRAS device sends a confirmation message to the terminal containing a first network access coefficient value and the first IP address, confirming whether the terminal chooses to consume the first network access coefficient value to obtain the first IP address. When the BRAS device receives a first reply message from the terminal confirming the consumption of the first network access coefficient value to obtain the first IP address, the BRAS device sends a first instruction message to the terminal, instructing the terminal to access the BRAS device using the first IP address. Thus, after sending an online request to the BRAS device, the terminal can, based on the BRAS device's confirmation message, choose whether to use a fixed IP address to access the BRAS device, depending on its needs, by consuming available network access coefficient values. This solves the technical problem of obtaining a fixed IP address when accessing the BRAS. Attached Figure Description

[0038] The address allocation method, apparatus, and storage medium provided in this disclosure are described in detail below with reference to the accompanying drawings.

[0039] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0040] The terms "first" and "second," etc., used in the specification and drawings of this application are used to distinguish different objects or to distinguish different treatments of the same object, rather than to describe a specific order of objects.

[0041] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0042] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0043] Figure 1 This is a schematic diagram of an address allocation device provided in an embodiment of this disclosure. Figure 1 As shown, the address allocation device 100 includes at least one processor 101, a communication line 102, and at least one communication interface 104, and may also include a memory 103. The processor 101, memory 103, and communication interface 104 are connected via the communication line 102.

[0044] The processor 101 may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of this disclosure, such as one or more digital signal processors (DSPs), or one or more field-programmable gate arrays (FPGAs).

[0045] Communication line 102 may include a path for transmitting information between the aforementioned components.

[0046] The communication interface 104 is used to communicate with other devices or communication networks. It can use any transceiver-like device, such as Ethernet, radio access network (RAN), wireless local area network (WLAN), etc.

[0047] The memory 103 may be a read-only memory (ROM) or other type of static storage device capable of storing static information and instructions, random access memory (RAM) or other type of dynamic storage device capable of storing information and instructions, or electrically erasable programmable read-only memory (EEPROM), compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical discs, laser discs, optical discs, digital universal optical discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium capable of including or storing desired program code having the form of instructions or data structures and accessible by a computer, but not limited thereto.

[0048] In one possible design, the memory 103 can exist independently of the processor 101, meaning the memory 103 can be an external memory of the processor 101. In this case, the memory 103 can be connected to the processor 101 via a communication line 102 to store execution instructions or application code, and its execution is controlled by the processor 101 to implement the space measurement and determination method provided in the following embodiments of this disclosure. In another possible design, the memory 103 can also be integrated with the processor 101, meaning the memory 103 can be an internal memory of the processor 101. For example, the memory 103 can be a cache, which can be used to temporarily store some data and instruction information.

[0049] As one possible implementation, processor 101 may include one or more CPUs, for example Figure 1 CPU0 and CPU1 in the example. Alternatively, the address allocation device 100 may include multiple processors, such as CPU0 and CPU1. Figure 1 The processors 101 and 107 are included. Alternatively, the address allocation device 100 may also include an output device 105 and an input device 106.

[0050] Through the above description of the implementation methods, those skilled in the art will clearly understand that, for the sake of convenience and brevity, only the division of the above functional modules is used as an example. In practical applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the network node can be divided into different functional modules to complete all or part of the functions described above. The specific working process of the system, modules, and network nodes described above can be referred to the corresponding process in the foregoing method embodiments, and will not be repeated here.

[0051] Currently, BRAS devices are used to provide broadband network access to public users. Furthermore, BRAS devices can provide users with functions including access, authentication, authorization, address allocation, and billing, depending on the user type. The types of users accessing the network include, but are not limited to, Point-to-Point Protocol over Ethernet (PPPoE), Internet Protocol over Ethernet (IPoE), and Dynamic Host Configuration Protocol (DHCP) + Web; authentication methods include, but are not limited to, Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP); and address allocation methods include, but are not limited to, DHCP, DHCPv6, and Stateless Address Autoconfiguration (SLAAC). Specifically, end users access BRAS devices through Customer Premise Equipment (CPE) devices, broadband dial-up users access BRAS devices through Digital Subscriber Line Access Multiplexer (DSLAM) devices, and fiber optic users access BRAS devices through Optical Network Unit (ONU) and Optical Line Terminal (OLT) devices.

[0052] The PPPoE authentication process comprises two phases: discovery and session. Specifically, in the discovery phase, the terminal discovers one or more network access devices. Further, the terminal selects one of these network access devices and sends its physical (Media Access Control, MAC) address to it. Upon receiving the terminal's MAC address, the network access device sends its own MAC address back to the terminal. The terminal and network access device exchange MAC addresses to generate a PPPoE Session_ID. It's important to note that the terminal and network access device remain connectionless before the session phase is established. After the session phase is established, both the terminal and network access device allocate resources to the Ethernet-based Point-to-Point Protocol (PPP) virtual interface used in the session phase.

[0053] The session phase includes the Link Control Protocol (LCP) and the Network Control Protocol (NCP). LCP is used for negotiation and authentication between the terminal and the network access device at the underlying link level. Specifically, the Radius server assists the terminal and network access device in authentication through the Password Authentication Protocol (PAP) and the Challenge Handshake Authentication Protocol (CHAP).

[0054] In the LCP negotiation section, the terminal and network access device exchange parameters such as MTU value and link type through messages like LCP config_Req, LCP config_Rej, LCP config_Nak, and LCP config_Ack. LCP config_Req is used for link negotiation requests. Specifically, when the receiving end does not support the configuration parameter type in the sending end's LCP config_Req message, it replies with the unsupported configuration parameter type information in the form of an LCP config_Rej reply message. When the receiving end receives a configuration parameter type that it supports in the sending end's LCP config_Req message but does not support the configuration parameter value in the LCP config_Req message, it replies with the unsupported configuration parameter value in the form of an LCPconfig_Nak reply message. Furthermore, when the negotiation is successful, the receiving end responds to the sending end with an LCPconfig_Ack message.

[0055] Specifically, such as Figure 2The diagram shows a flowchart of a terminal accessing another terminal via PPPoE. The steps are as follows: Step 201: The terminal sends an address allocation request to the BRAS via IP address 0*.0*.0*.0*; Step 202: The BRAS returns a request message to the terminal containing the initial address 10*.10*.10*.10*; Step 203: The terminal confirms the initial IP address with the BRAS; Step 204: The BRAS reallocates a new IP address to the host, 123*.0*.0*.1*; Step 205: The terminal initiates a request message to the BRAS via IP address 123*.0*.0*.1*; Step 206: The BRAS returns access confirmation information to the terminal; Step 207: The terminal sends handshake information to the BRAS; Step 208: The BRAS replies with handshake confirmation information to the terminal; Step 209: The terminal sends a disconnection request to the BRAS; Step 2010: The BRAS returns disconnection confirmation information to the terminal.

[0056] In related technologies, Broadband Remote Access Servers (BRAS) employ a dynamic Internet Protocol (IP) address allocation mechanism. When an end user sends a disconnect request to the BRAS device and breaks the connection, and then sends a reconnection request, the BRAS device dynamically selects an IP address randomly from its IP address pool and assigns it to the end user. This results in the end user receiving a different IP address than the one previously obtained. Therefore, how to assign a fixed IP address to the end user based on their needs is a pressing technical problem that needs to be solved.

[0057] To effectively control network traffic in hotspot areas, this disclosure provides an address allocation method. A terminal sends an online message to a Broadband Access Server (BRAS) to obtain an IP address and request access to the BRAS device. Upon receiving the online message, the BRAS device determines whether the first IP address previously allocated to the terminal exists in the address set to be allocated, based on the terminal's identifier contained in the message. If the first IP address exists, the BRAS device sends a confirmation message to the terminal containing a first network access coefficient value and the first IP address, confirming whether the terminal chooses to consume the first network access coefficient value to obtain the first IP address. After receiving a first reply message from the terminal confirming the consumption of the first network access coefficient value to obtain the first IP address, the BRAS device sends a first instruction message to the terminal, instructing the terminal to access the BRAS device using the first IP address. Thus, after sending an online request to the BRAS device, the terminal can, based on the BRAS device's confirmation message, choose whether to use a fixed IP address to access the BRAS device, depending on its needs. This solves the technical problem of obtaining a fixed IP address when accessing the BRAS.

[0058] The address allocation method provided in this disclosure can be applied to, for example, Figure 1 In the address allocation device shown, such as Figure 3 As shown, the address allocation method provided in this embodiment can be implemented through the following steps 301 to 305.

[0059] Step 301: The terminal sends an online message to the Broadband Access Server (BRAS). Correspondingly, the BRAS receives the online message sent by the terminal.

[0060] The online notification includes: the terminal's identifier.

[0061] In one possible implementation, when a terminal sends an online message to the BRAS for the first time, the BRAS device returns a request message containing an initial IP address to the terminal, such as 10*.10*.10*.10*. After receiving the request message from the BRAS device, the terminal confirms the received initial IP address with the BRAS device. Further, the BRAS device sends a new IP address to the terminal, such as 123*.0*.0*.1*. After receiving the new IP address, the terminal initiates a request message to the BRAS using the new IP address. After receiving the request message, the BRAS device returns an acknowledgment message to the terminal, completing the IP address allocation for the terminal's first online session. After the terminal goes offline, when it sends an online message to the BRAS again, the BRAS device, upon receiving the online message from the terminal, checks whether the IP address obtained during the terminal's first online session (123*.0*.0*.1*) exists in the set of IP addresses to be allocated. If it exists, the BRAS device will reassign the IP address 123*.0*.0*.1* to the terminal.

[0062] Step 302: BRAS determines whether there is a first Internet Protocol IP address corresponding to the terminal's identifier in the set of addresses to be allocated.

[0063] The first IP address is the IP address used when the terminal last went online.

[0064] In one possible implementation, after receiving the online message sent by the terminal, the BRAS device determines whether there is a first IP address corresponding to the terminal identifier in the set of addresses to be allocated, such as 123*.0*.0*.1*, based on the terminal identifier contained in the online message.

[0065] Step 303: If the first IP address exists in the set of addresses to be allocated, the BRAS sends an acknowledgment message to the terminal. Correspondingly, the terminal receives the acknowledgment message sent by the BRAS.

[0066] The confirmation information includes: a first network access coefficient value and a first IP address; the first network access coefficient value is used to characterize the coefficient value required to obtain the first IP address.

[0067] In one possible implementation, if the BRAS device determines that a first IP address corresponding to the terminal identifier exists in the set of addresses to be allocated, the BRAS device sends a confirmation message to the terminal containing a first network entry coefficient value and the first IP address, determining whether the terminal should consume the first network entry coefficient value to obtain the first IP address. Correspondingly, after receiving the confirmation message from the BRAS, the terminal can choose whether to consume the first network entry coefficient value to obtain the first IP address.

[0068] In one example, when the BRAS device determines that a first IP address, such as 123*.0*.0*.1*, exists in the set of addresses to be allocated, the BRAS device sends a confirmation message to the terminal to determine whether the terminal chooses to consume the first network entry coefficient value to obtain the first IP address.

[0069] Optionally, when the BRAS device determines that the first IP address (e.g., 123*.0*.0*.1*) does not exist in the set of addresses to be allocated, the BRAS allocates a second IP address to the terminal and sends a second indication message to the terminal. The second IP address is an IP address in the set of addresses to be allocated that is different from the first IP address, and the second indication message is used to instruct the terminal to access the BRAS device according to the second IP address.

[0070] It should be noted that the value of the first network access coefficient is determined by the time interval between the terminal's previous offline and re-online periods and a fixed coefficient. For example, if the first network access coefficient is M, the time interval between the terminal's previous offline and re-online periods is T1, and the fixed coefficient set by the BRAS device is D1, then M = T1 × D1. Here, D1 is a fixed coefficient, which can be set by the network operator or the BRAS device based on the number of available IP addresses; this disclosure does not impose any restrictions.

[0071] Step 304: If the terminal confirms that it is using the first IP address to access the BRAS and that the terminal's available network access coefficient value is greater than or equal to the first network access coefficient value, the terminal consumes the first network access coefficient value and sends a first reply message to the BRAS. Accordingly, the BRAS receives the first reply message.

[0072] The first response information is used to indicate that the terminal determines to consume the first network access coefficient value to obtain the first IP address; the first indication information is used to instruct the terminal to access the BRAS according to the first IP address.

[0073] In one possible implementation, when the terminal confirms that it will use the first IP address to access the BRAS device, and the terminal confirms that the currently available network access coefficient value is greater than or equal to the first network access coefficient value, it sends a first reply message containing the first network access coefficient value to the BRAS device. Simultaneously, the terminal's available network access coefficient value is reduced by the first network access coefficient value. Correspondingly, the BRAS device receives the first reply message sent by the terminal.

[0074] It should be noted that the terminal's available network access coefficient value can increase by a certain preset amount every preset time interval. For example, the terminal's default available network access coefficient value is N, and the available network access coefficient value increased by N' every preset time interval, where N' can be determined by a time coefficient T' and a fixed coefficient D'. Specifically, N' = T' × D', where the time coefficient T' increases with time in each time interval. When T' × D' = 1, the available network access coefficient value N increases by N', and thereafter the terminal's available network access coefficient value is N + N'. At the same time, the time coefficient T' returns to zero and increases with time in the next time interval.

[0075] Step 305: Upon receiving the first response information from the terminal, the BRAS sends a first instruction information to the terminal. Correspondingly, the terminal receives the first instruction information.

[0076] The first indication information is used to instruct the terminal to access the BRAS according to the first IP address.

[0077] In one possible implementation, upon receiving a first reply from the terminal, the BRAS device sends a first instruction to the terminal, instructing the terminal to access the BRAS device using a first IP address. Correspondingly, after receiving the first instruction, the terminal sends a handshake request to the BRAS device using the first IP address. Further, the BRAS device returns a handshake confirmation to the terminal and establishes a connection.

[0078] The above scheme brings at least the following beneficial effects: The terminal sends an online message to the Broadband Access Server (BRAS) to obtain an IP address and request access to the BRAS device. Upon receiving the online message from the terminal, the BRAS device determines, based on the terminal's identifier contained in the online message, whether the first IP address allocated to the terminal during its last online session exists in the set of addresses to be allocated. If the first IP address exists in the set of addresses to be allocated, the BRAS device sends a confirmation message to the terminal containing a first network entry coefficient value and the first IP address, confirming that the terminal has chosen to consume the first network entry coefficient value to obtain the first IP address. Correspondingly, after receiving the confirmation message from the BRAS device, if the terminal confirms the use of the first IP address and its available network entry coefficient value is greater than or equal to the first network entry coefficient value, it subtracts the first network entry coefficient value from its available network entry coefficient value and sends a first reply message to the BRAS device confirming the acquisition of the first IP address. Upon receiving the first network entry information from the terminal, the BRAS device returns a first instruction message to the terminal, instructing the terminal to access the BRAS device based on the first IP address. In this way, after the terminal sends an online request to the BRAS device, based on the confirmation information from the BRAS device, it can choose whether to use a fixed IP address to access the BRAS device by consuming available network access coefficients. This solves the technical problem of the terminal obtaining a fixed IP address when accessing the BRAS.

[0079] Combination Figure 3 ,like Figure 4 As shown, after the BRAS sends the confirmation information to the terminal in step 303, the steps 401-402 are also included.

[0080] Step 401: If the terminal confirms that it will not use the first IP address to access the BRAS, and / or the terminal's available network access coefficient value is less than the first network access coefficient value, the terminal sends a second reply message to the BRAS.

[0081] The second response information is used to indicate that the terminal determines that it will not consume the first network access coefficient value to obtain the first IP address.

[0082] In one possible implementation, after receiving the confirmation information from the BRAS device, the terminal confirms whether to use the first IP address to access the BRAS device. When the terminal determines that it will not use the first IP address, and / or the terminal's current available network access coefficient value is less than the first network access coefficient value, the terminal sends a second reply information to the BRAS device, confirming that it will not consume the first network access coefficient value to obtain the first IP address.

[0083] In one example, when the terminal's available network access coefficient is 50 and the first network access coefficient is 80, the terminal sends a second response message to the BRAS device.

[0084] Step 402: Upon receiving the second response information from the terminal, the BRAS sends a second instruction information to the terminal. Correspondingly, the terminal receives the second instruction information sent by the BRAS.

[0085] The second instruction information is used to instruct the terminal to access the BRAS according to the second IP address.

[0086] In one possible implementation, after receiving a second response from the terminal confirming that it will not use the first IP address, the BRAS device sends a second instruction to the terminal and assigns a second IP address to the terminal. Correspondingly, after receiving the second instruction from the BRAS, the terminal sends handshake information to the BRAS device via the second IP address. The BRAS device returns handshake confirmation information to the terminal, thereby establishing a connection with the terminal via the second IP address.

[0087] The above scheme brings at least the following beneficial effects: After receiving the confirmation information sent by the BRAS device, the terminal confirms that it will not use the first IP address. Alternatively, if the terminal determines that the available network access coefficient value is less than the first network access coefficient value and cannot pay the first network access coefficient value to obtain the first IP address, the terminal sends a second reply information to the BRAS device to indicate that the terminal will not consume the first network access coefficient value to obtain the first IP address. Correspondingly, after receiving the second reply information from the terminal, the BRAS device assigns a second IP address to the terminal and sends a second instruction information, instructing the terminal to connect to the BRAS device through the second IP address. In this way, when the terminal chooses not to obtain a fixed IP address or determines that it does not meet the conditions for obtaining a fixed IP address, the BRAS device ensures that the terminal can establish a normal connection with the BRAS device by assigning a new IP address to the terminal.

[0088] Combination Figure 3 ,like Figure 5 As shown, before step 301 or after step 305, i.e., when the terminal and the BRAS device are in a connected state, the following steps 501-502 are also included.

[0089] Step 501: The terminal sends a shutdown message to the BRAS. Correspondingly, the BRAS receives the shutdown message sent by the terminal.

[0090] The offline message is used to instruct the BRAS to disconnect from the terminal.

[0091] Step 502: BRAS stores the first IP address in the set of addresses to be assigned.

[0092] The first IP address will not be allocated to any terminal other than the terminal within a preset time period. The preset time period is determined based on the ratio of the number of IP addresses to be allocated in the set of addresses to the total capacity of the BRAS IP address pool.

[0093] In one possible implementation, after the BRAS device disconnects from the terminal, it stores the first IP address in a set of addresses to be assigned. The BRAS device will retain the first IP address for a preset period of time and will not assign it to any other terminal during that time.

[0094] In one example, after the BRAS device disconnects from the terminal, it saves the first IP address to the set of addresses to be assigned according to a set initial storage period. The initial storage period can be set, but is not limited to, 48 hours. During the initial storage period of 48 hours, the BRAS device will not assign the first IP address to any other terminal besides the aforementioned terminal. If, within the initial storage period of 48 hours, the BRAS device receives a reconnection message from the aforementioned terminal, the BRAS device will continue to execute steps 301-305.

[0095] Optionally, when the ratio of the number of addresses to be allocated in the set of addresses to be allocated to the total capacity of the BRAS device's IP address pool is less than a certain threshold, the BRAS device will shorten the retention period of the first IP address. For example, when the ratio of the number of addresses to be allocated in the set of addresses to be allocated to the total capacity of the BRAS device's IP address pool is less than 0.85, the BRAS device will shorten the preset retention period of the first IP address to 24 hours. When the ratio of the number of addresses to be allocated in the set of addresses to be allocated to the total capacity of the BRAS device's IP address pool is less than 0.7, the BRAS device will shorten the preset retention period of the first IP address to 0 hours.

[0096] It should be noted that the preset duration for which the BRAS device retains the first IP address can be adjusted and set by increasing or decreasing the number of IP addresses to be allocated in the set of addresses to be allocated, as well as the size of the network and users.

[0097] The above scheme offers at least the following benefits: The terminal sends an offline message to the BRAS device, and correspondingly, upon receiving the offline message, the BRAS device disconnects from the terminal. Simultaneously, the IP address assigned to the terminal is stored in the set of addresses to be assigned and preserved for a preset time period. Thus, when the terminal requests to reconnect within this preset time period, the terminal can preferentially assign this IP address, satisfying the terminal's need to obtain a fixed IP address within a preset time period.
