[0002] This application claims priority to Chinese Patent Application No. 202411842928.4, filed on December 13, 2024, entitled "Communication Method and Broadband Access Server Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of communication technology, and in particular to a communication method and a broadband access server device. Background Technology

[0004] A control-and-forward separation vBRAS (Virtual Broadband Remote Access Server) device consists of two parts: a CP (Control Plane) and a UP (User Plane). The CP and UP communicate via the CP interface protocol. In related technologies, to prevent CP malfunctions, a dual-machine hot standby networking mode is typically used between CPs, i.e., two CPs are connected to the same UP. However, in this networking mode, if the UP is working normally, but all CPs connected to the UP experience device malfunctions, user data cannot be forwarded normally. Therefore, how to ensure the normal forwarding of user data even in the event of a complete network interruption between the CP and UP is one of the urgent problems to be solved. Summary of the Invention

[0005] The purpose of this application is to provide a communication method and a broadband access server device to solve the problem that users cannot go online after the UP and CP networks are interrupted, resulting in the UP being unable to process user data.

[0021] This application provides a communication method and a broadband access server device to solve the problem that users cannot go online after the UP and CP networks are interrupted, resulting in the UP being unable to process user data.

[0022] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0023] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein.

[0024] Figure 1 is a schematic structural diagram of a vBRAS device according to an embodiment of this application. As shown in Figure 1, the vBRAS device includes a CP and a UP. The CP and UP communicate with each other through the CP interface protocol, which includes a protocol interface, a control interface, and a management interface. The CP can implement user management, user access control, UP management, address management, etc., while the UP can implement traffic forwarding, traffic statistics, unicast routing, multicast routing, user access control, address management, etc.

[0025] Figure 2 is a schematic flowchart of a communication method according to an embodiment of this application, which is applied to the UP shown in Figure 1. As shown in Figure 2, the method includes the following steps S102-S104.

[0026] S202, when the communication connection with the CP is broken, a network access request from the first user is received.

[0027] The network access request of the first user may carry the user information of the first user, which may include at least one of the following: the username, password, name, phone number, and identity code used by the user to access the UP.

[0028] S204, assign a first network access address to the first user, and establish a network connection for the first user based on the first network access address.

[0029] In one example, when the UP assigns a first network access address to the first user, it selects the first network access address from the UP's preset address pool and assigns it to the first user. The preset address pool includes multiple network access addresses, which are pre-assigned network access addresses to the UP.

[0030] In one instance, multiple network access addresses in a pre-defined address pool are pre-assigned to the UP by the CP.

[0031] In one example, when the UP assigns a first network access address to the first user, it selects different methods to allocate the address based on whether the first user is a new user or a user already saved in the UP. A user already saved in the UP refers to a user whose user information is stored in the UP, i.e., an existing user who has previously established a network connection with the UP. After establishing a network connection for a user, the UP can associate the user's network access address with the user information and store it locally, for example, associating the user's network access address with the username. Thus, upon receiving a network access request from the first user, the UP can first determine whether the first user is a new user or a user already saved in the UP based on the user information carried in the network access request, and then select the appropriate method to assign the first network access address accordingly.

[0032] In response to the first user being a new user, the UP selects a first network access address from the preset address pool and assigns it to the first user. This first network access address is not assigned to any other user.

[0033] In response to the first user being a user already saved in the UP, the first network access address corresponding to the first user, already saved in the UP, is assigned to the first user. This first network access address corresponding to the first user is the first network access address associated with the first user's user information and stored in the UP. That is, if the communication connection with the CP is broken, and the first user is a user already saved in the UP, it means that the first user had already established a communication connection with the UP before the communication connection between the UP and CP was broken, and the first user lost connection due to the break in the communication connection between the UP and CP. In this case, the UP assigns the network access address used by the first user when connecting to the UP, enabling the first user to quickly restore the communication connection with the UP.

[0034] Furthermore, if the first user is an existing user, the UP can also select an unassigned network access address from the preset address pool and assign it to the first user. That is, during the period when the communication connection between the UP and CP is interrupted, if an existing user requests access, the UP can disregard the network access address used by the existing user when accessing the UP, and instead select a new network access address from the preset address pool for allocation. The newly selected network access address can be the same as or different from the network access address previously used by the existing user.

[0035] In one instance, the UP does not need to authenticate the first user before assigning the first network access address. That is, after receiving the first user's network access request, the UP directly assigns the first network access address to the first user.

[0036] In one example, a pre-configured fault protection period of a predetermined duration is set. During the fault protection period, the UP can act as an agent for the CP to execute steps S202-S204. If the communication connection between the CP and the UP has not been restored after the fault protection period expires, the UP can disconnect the communication connection with the first user. The predetermined duration of the fault protection period can be configured according to actual business needs.

[0037] In this embodiment, the UP assigns the first network access address to the first user using a DHCP (Dynamic Host Configuration Protocol) proxy. That is, the UP acts as a proxy for the CP to assign the first network access address to the first user.

[0038] By employing the technical solution of this application embodiment, when the communication connection between the UP and CP is disconnected, after the UP receives the network access request from the first user, it assigns a first network access address to the first user and establishes a network connection for the first user based on the first network access address. It is evident that even when the communication connection between the UP and CP is disconnected, the UP can independently assign a first network access address to the requesting first user without interacting with the CP or waiting for the CP to reconnect. Therefore, it can still ensure the normal processing of user data, effectively improving the stability of the UP in processing user data and enhancing the user's network experience.

[0039] In one embodiment, after establishing a network connection for a first user based on a first network access address, the UP can restrict the first user's first type of service requests.

[0040] The first type of business request is determined based on preset rules. These preset rules indicate the types of businesses that are restricted and may include at least one of the following: businesses with an importance level higher than or equal to a specified level, or businesses of a specified type. If the business type corresponding to a business request matches the business type indicated by the preset rules, the business request is determined to belong to the first type of business request.

[0041] In one example, a corresponding business importance level is pre-configured for each type of business. For example, the business importance level is represented by numbers such as Level 1, Level 2, Level 3, etc., with higher numbers indicating higher business importance. Assuming the specified level is 2, if the business importance level of the first user's business request is higher than or equal to 2 (i.e., a business request at Level 2 or above), then the business request will be identified as a Class 1 business request and subject to business restrictions.

[0042] In one example, specific service types are pre-configured, such as configuring some non-basic services as specific service types. If the service requested by the first user belongs to a specific service type, i.e., a non-basic service, then the service request will be identified as a first-type service request and subject to service restrictions, so that only the first user's service requests for basic services can be processed.

[0043] In one instance, restricting the first type of business request can be done by: refusing to process the first type of business request.

[0044] In this embodiment, since the first user's first network access address is directly assigned by the UP, the identity of the first user is unknown to the UP. By restricting the first user's first type of service requests, the UP only processes the first user's basic services or services with low service importance. This ensures that user data processing continues while maintaining service processing security even when the communication connection between the UP and CP is lost.

[0045] In one embodiment, upon restoration of the communication connection with the CP, in response to successful authentication of the first user, the service restriction on the first user's first type of service request is lifted. After the service restriction on the first user's first type of service request is lifted, the UP can process the first user's first type of service request.

[0046] In one instance, upon restoration of communication with the CP, the CP authenticates the first user and sends the authentication result to the UP. The authentication result may be either authentication failed or authentication succeeded.

[0047] Once the first user's identity is successfully authenticated, the UP can proactively lift the service restrictions on the first user's first type of service requests, or it can lift the service restrictions on the first user's first type of service requests after receiving a lifting instruction from the CP for the first user.

[0048] In this embodiment, when the first user's identity authentication is successful, the service restriction on the first user's first type of service request is lifted in a timely manner, so that the first user who accessed the UP during the period when the communication connection between the UP and CP is disconnected can request to process higher-level services after identity authentication is successful, thereby improving the user's network usage experience.

[0049] In one embodiment, upon restoration of the communication connection with the CP, in response to successful authentication of the first user, the user information and the first network access address of the first user are recorded in the UP.

[0050] In one example, the UP maintains a user information table. This table records user information for users who establish communication connections with the UP, as well as the network access address used by the user when establishing the communication connection with the UP. User information may include at least one of the following: username, password, name, phone number, and unique identification code used by the user to access the UP.

[0051] Once the first user's identity is successfully authenticated, the UP can associate the first user's user information and the first network access address in the user information table, thus recording the first user as a "returning user." This allows the UP to retrieve the first user's information from the user information table the next time the user connects, and establish a network connection for the first user based on the first network access address associated with that information.

[0052] In one embodiment, if the communication connection with the CP is restored, the communication connection with the first user is disconnected in response to the first user's authentication failure.

[0053] In one instance, upon restoration of communication with the CP, the CP authenticates the first user and sends the authentication result to the UP. The authentication result may be either authentication failed or authentication succeeded.

[0054] If the first user's authentication fails, the UP can proactively disconnect the communication connection with the first user, or it can disconnect the communication connection with the first user after receiving a disconnection instruction from the CP for the first user.

[0055] In this embodiment, if the first user fails to authenticate, the communication connection with the first user is disconnected, so that the user who failed to authenticate can be kicked out in time, ensuring that all users communicating with the UP are authenticated users, thus improving communication security.

[0056] In one embodiment, if the communication connection between the UP and CP is broken, users who have already established a network connection with the UP can remain online. The UP will not actively kick users offline, thereby avoiding service interruption caused by the break in the communication connection between the UP and CP and improving the stability of the UP in processing user data.

[0057] Figure 3 is a schematic flowchart of a communication method according to an embodiment of this application, which is applied to the CP shown in Figure 1. As shown in Figure 3, the method includes the following steps S302-S306.

[0058] S302, if the communication connection with UP is restored, obtain the user information of the first user, who was connected to UP when the communication connection between CP and UP was broken.

[0059] The user information may include at least one of the following: the username, password, and address information used by the user to access the UP. The first network connection address used by the first user to connect to the UP is assigned by the UP. The first user can be a new user or an existing user. A new user refers to a user who has never established a network connection with the UP, or a user who has established a network connection with the UP but whose lease period has expired. An existing user refers to a user who has previously established a network connection with the UP and whose user information is stored in the UP.

[0060] In one instance, if the communication connection with the UP is restored, the UP proactively sends the first user's information to the CP. Alternatively, the CP instructs the UP to send the first user's information, and the UP, based on the CP's instruction, sends the first user's information to the CP.

[0061] S304, based on user information, performs identity authentication for the first user.

[0062] The user information includes authentication information used to verify the identity of the first user. Authentication information may be part or all of the user information.

[0063] In one example, the CP pre-stores a user information table, which records the user information of users who have passed authentication. The user information may include at least one of the following: the username, password, name, phone number, and unique identification code used by the user to access the UP.

[0064] When CP authenticates the first user, it compares the first user's information with the user information table. If the user information table contains the first user's information, the authentication is successful. If the user information table does not contain the first user's information, the authentication is unsuccessful.

[0065] S306, in response to successful authentication, records the allocation status of the first user's first network access address.

[0066] The allocation status indicates that the first network access address has been allocated to the first user. The CP records the allocation status of the first user's first network access address, which can be done as follows: the CP records the association between the first network access address and the user information of the first user, and this association indicates that the first network access address has been allocated to the first user.

[0067] In this embodiment, after the communication connection between the CP and UP is restored and the identity of the first user is successfully authenticated, the CP does not need to reassign a new network access address to the first user. Instead, by recording the allocation status of the first network access address assigned to the first user by the UP, the first user can continue to use the first network access address to communicate with the UP. This process can be referred to as the CP's reservation behavior for the first network access address after going online.

[0068] By employing the technical solution of this application embodiment, when the communication connection between the CP and UP is restored, the first user accessing the UP is authenticated, and after successful authentication, the allocation status of the first user's first network access address is recorded, thus achieving "placement" of the first network access address. This "placement" method not only avoids the first network access address being repeatedly allocated to other users, but also allows the first user to continue using the first network access address to communicate with the UP without the need for the CP to reallocate a new network access address after the communication connection between the UP and CP is restored. This avoids the first user's connection being interrupted due to the CP's re-connection, ensuring service continuity and improving the stability of the UP in processing user data.

[0069] In one embodiment, in response to failed authentication, the CP instructs the UP to disconnect the communication connection with the first user. By instructing the UP to disconnect the communication connection with the first user, the user whose authentication failed can be promptly removed, ensuring that all users communicating with the UP are authenticated users, thus improving communication security.

[0070] In one embodiment, in response to successful authentication, the CP instructs the UP to remove service restrictions on the first user. By instructing the UP to remove service restrictions on the first user's first type of service requests, the first user who accessed the UP during the period when the communication connection between the UP and CP was interrupted can request processing of higher-level services after successful authentication, thereby improving the user's network experience.

[0071] The communication method provided in this application will be illustrated below through examples.

[0072] Figure 4 is a schematic structural diagram of a vBRAS device according to another embodiment of this application. As shown in Figure 4, the vBRAS device includes a UP and two CPs, CP1 and CP2, which are hot-standby protections for each other. A communication connection between the UP and at least one of CP1 or CP2 can be considered a communication connection between the UP and the CP. The UP stores a preset address pool and a user information table. The preset address pool includes multiple network access addresses pre-allocated by the CPs. The user information table records user information of users who establish network connections with the UP, as well as the network access addresses used when users establish network connections with the UP. In Figure 4, the UP establishes network connections with users 1, 2, and 3, and forwards user data for users 1, 2, and 3.

[0073] In this scenario, User 1 connected before the communication connection between the UP and CP was broken, while Users 2 and 3 connected during the period when the communication connection between the UP and CP was broken. Assume User 1 is an existing user, User 2 is a new user, and User 3 is an illegitimate new user. An existing user is one who has previously established a network connection with the UP and whose user information is stored in the UP. A new user is one who has never established a network connection with the UP, or one who has established a network connection but whose lease has expired. An illegitimate user is one whose identity authentication failed or who did not perform identity authentication.

[0074] During the communication connection between UP and CP, CP assigns network access address 1 to user 1, and UP establishes a network connection with user 1 based on network access address 1. UP stores user 1's user information in the user information table.

[0075] At a certain point, the UP detects a disconnection in the communication connection with the CP, entering a fault protection period. During this time, the UP maintains a network connection with User 1 and continues to process User 1's service requests. After User 1's lease expires, the UP disconnects from User 1. The UP then maintains a continuous network connection with User 1 regardless of User 1's lease period.

[0076] During the fault protection period, User 2 sends a network access request to UP. UP does not find User 2's user information in its local user information table, thus determining that User 2 is a new user. UP does not authenticate User 2, but directly selects an unassigned network access address 2 from its local preset address pool and assigns it to User 2, establishing a network connection for User 2 based on network access address 2.

[0077] During the fault protection period, User 3 sends a network access request to UP. UP does not find User 3's information in its local user information table, thus determining User 3 to be a new user. UP does not authenticate User 3, but directly selects an unassigned network access address 3 from its local preset address pool and assigns it to User 3, establishing a network connection for User 3 based on the network access address 3.

[0078] At some point later, the communication connection between CP1 and UP is restored, entering the fault recovery period. At this time, CP1 obtains the user information of users who accessed the UP during the fault protection period, including user information for user 1, user 2, and user 3. CP1 authenticates the users who accessed the UP during the fault protection period, comparing the user information of user 1, user 2, and user 3 with its local user table, which records the user information of users who passed authentication. Since user 1 accessed the UP before the communication connection between UP and CP was broken, it means that user 1 has been authenticated by either CP1 or CP2 and the authentication was successful. Therefore, CP1's user table must contain user information for user 1, and CP1 determines that user 1's authentication was successful. Since users 2 and 3 both accessed the UP during the period when the communication connection between UP and CP was broken, they were not authenticated when connecting to the UP. Assuming that CP1 finds user information for user 2 in its user table but not for user 3, then user 2 is determined to be a legitimate new user, and user 3 is an illegitimate new user. Then, CP1 can instruct UP to disconnect the network connection with user 3. Following CP1's instructions, UP disconnects the network connection with user 3 and stops data forwarding from user 3.

[0079] Furthermore, since user 2's network access address 2 is assigned by UP, after CP1 authenticates user 2, it records the assignment status of network access address 2 to indicate that network access address 2 has been assigned to user 2. This prevents network access address 2 from being repeatedly assigned to other users and allows user 2 to continue using network access address 2 without having to go offline and then come back online, ensuring the continuity of user 2's data forwarding.

[0080] As can be seen, the communication method of this application embodiment can still achieve continuity in user data forwarding and network access for new users even if the communication connection between UP and CP is completely disconnected. Furthermore, after the communication connection between UP and CP is restored, the "placeholder" processing of the network access address by CP ensures that UP's forwarding and online access for users are unaffected, and that data forwarding for legitimate users (i.e., users whose identities have been authenticated) is uninterrupted, greatly improving the stability of user data forwarding.

[0081] In summary, specific embodiments of this subject matter have been described. Other embodiments are within the scope of the appended claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve the desired result. Furthermore, the processes depicted in the drawings do not necessarily require a specific or sequential order to achieve the desired result. In some embodiments, multitasking and parallel processing can be advantageous.

[0082] The above are the communication methods provided in the embodiments of this application. Based on the same idea, the embodiments of this application also provide a broadband access server device.

[0083] Figure 5 is a schematic block diagram of a broadband access server device according to an embodiment of this application. In this embodiment, the broadband access server device is UP. As shown in Figure 5, the UP includes: a receiving module 51, used to receive a network access request from a first user when the communication connection with the CP is disconnected; and a network connection module 52, used to allocate a first network access address to the first user and establish a network connection for the first user based on the first network access address.

[0084] In one embodiment, when the network connection module 52 assigns a first network access address to the first user, it performs the following steps: in response to the first user being a new user, it selects the first network access address from the preset address pool of the UP and assigns the first network access address to the first user; wherein, the preset address pool includes multiple network access addresses, and the multiple network access addresses are network access addresses pre-assigned to the UP.

[0085] In one embodiment, when the network connection module 52 allocates a first network access address to the first user, it performs the following steps: in response to the first user being a user already saved in the UP, it allocates the first network access address corresponding to the first user already saved in the UP to the first user.

[0086] In one embodiment, the UP further includes: a restriction module, configured to restrict a first type of service request of the first user after establishing a network connection for the first user based on the first network access address, wherein the first type of service request is determined based on a preset rule.

[0087] In one embodiment, the UP further includes: a disconnection module, configured to disconnect the communication connection with the first user in response to the first user's authentication failure, provided that the communication connection with the CP is restored.

[0088] In one embodiment, the UP further includes: a derestriction module, configured to, upon restoration of the communication connection with the CP, remove the service restriction on the first type of service request of the first user in response to successful authentication of the first user.

[0089] By employing the technical solution of this application embodiment, when the communication connection between the UP and CP is disconnected, after the UP receives the network access request from the first user, it assigns a first network access address to the first user and establishes a network connection for the first user based on the first network access address. It is evident that even when the communication connection between the UP and CP is disconnected, the UP can independently assign a first network access address to the requesting first user without interacting with the CP or waiting for the CP to reconnect. Therefore, it can still ensure the normal processing of user data, effectively improving the stability of the UP in processing user data and enhancing the user's network experience.

[0090] Those skilled in the art will understand that the broadband access server device in Figure 5 can be used to implement the communication method applied to UP described above. The detailed description should be similar to that described in the method section above, and will not be repeated here to avoid redundancy.

[0091] Figure 6 is a schematic block diagram of a broadband access server device according to another embodiment of this application. In this embodiment, the broadband access server is a CP. As shown in Figure 6, the CP includes: an acquisition module 61, used to acquire user information of a first user when the communication connection between the CP and the UP is restored; the first user is connected to the UP when the communication connection between the CP and the UP is disconnected; an authentication module 62, used to authenticate the first user based on the user information; and a recording module 63, used to record the allocation status of the first network access address of the first user in response to successful authentication.

[0092] In one embodiment, the CP further includes: an indication module, configured to, in response to the authentication failure, indicate disconnection of the communication connection with the first user; or, in response to the authentication success, indicate cancellation of service restrictions on the first user.

[0093] By employing the technical solution of this application embodiment, when the communication connection between the CP and UP is restored, the first user accessing the UP is authenticated, and after successful authentication, the allocation status of the first user's first network access address is recorded, thus achieving "placement" of the first network access address. This "placement" method not only avoids the first network access address being repeatedly allocated to other users, but also allows the first user to continue using the first network access address to communicate with the UP without the need for the CP to reallocate a new network access address after the communication connection between the UP and CP is restored. This avoids the first user's connection being interrupted due to the CP's re-connection, ensuring service continuity and improving the stability of the UP in processing user data.

[0094] Those skilled in the art will understand that the broadband access server device in Figure 6 can be used to implement the communication method applied to CP described above. The detailed description should be similar to that described in the method section above, and will not be repeated here to avoid redundancy.

[0095] Based on the same idea, this application also provides an electronic device, as shown in FIG7. The electronic device can vary considerably due to differences in configuration or performance, and may include one or more processors 701 and memories 702. The memories 702 may store one or more application programs or data. The memories 702 may be temporary or persistent storage. The application programs stored in the memories 702 may include one or more modules (not shown), each module including a series of computer-executable instructions for the electronic device. Furthermore, the processor 701 may be configured to communicate with the memories 702 and execute the series of computer-executable instructions stored in the memories 702 on the electronic device. The electronic device may also include one or more power supplies 703, one or more wired or wireless network interfaces 704, one or more input / output interfaces 705, and one or more keyboards 706.

[0096] In this embodiment, the electronic device includes a memory and one or more programs, wherein one or more programs are stored in the memory, and one or more programs may include one or more modules, and each module may include a series of computer-executable instructions for the electronic device, and is configured to be executed by one or more processors. The one or more programs include computer-executable instructions for performing the following: receiving a network access request from a first user when the communication connection with the control plane CP is disconnected; assigning a first network access address to the first user; and establishing a network connection for the first user based on the first network access address.

[0097] By employing the technical solution of this application embodiment, when the communication connection between the UP and CP is disconnected, after the UP receives the network access request from the first user, it assigns a first network access address to the first user and establishes a network connection for the first user based on the first network access address. It is evident that even when the communication connection between the UP and CP is disconnected, the UP can independently assign a first network access address to the requesting first user without interacting with the CP or waiting for the CP to reconnect. Therefore, it can still ensure the normal processing of user data, effectively improving the stability of the UP in processing user data and enhancing the user's network experience.

[0098] In another embodiment, the electronic device includes a memory and one or more programs, wherein one or more programs are stored in the memory, and the one or more programs may include one or more modules, and each module may include a series of computer-executable instructions for use in the electronic device, and is configured to be executed by one or more processors. The one or more programs include computer-executable instructions for performing the following: upon restoration of communication connection with the forwarding plane UP, obtaining user information of a first user; the first user being connected to the UP when the communication connection between the CP and the UP was disconnected; authenticating the first user based on the user information; and recording the allocation status of the first network access address of the first user in response to successful authentication.

[0099] By employing the technical solution of this application embodiment, when the communication connection between the CP and UP is restored, the first user accessing the UP is authenticated, and after successful authentication, the allocation status of the first user's first network access address is recorded, thus achieving "placement" of the first network access address. This "placement" method not only avoids the first network access address being repeatedly allocated to other users, but also allows the first user to continue using the first network access address to communicate with the UP without the need for the CP to reallocate a new network access address after the communication connection between the UP and CP is restored. This avoids the first user's connection being interrupted due to the CP's re-connection, ensuring service continuity and improving the stability of the UP in processing user data.
