Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and a broadband access server device. Background Art

[0002] The vBRAS (Virtual Broadband Remote Access Server) device with separated control and forwarding includes two parts: CP (Control Plane) and UP (User Plane). Communication between CP and UP is achieved through the CP interface protocol. In related technologies, in order to prevent CP abnormalities, a dual-machine hot standby networking mode is usually used between CPs, that is, two CPs are connected to the same UP. However, in the networking mode, if the UP works normally but all CPs connected to the UP have equipment operation abnormalities, user data cannot be forwarded normally. Therefore, how to ensure the normal forwarding of user data when the network between CP and UP is completely interrupted is one of the problems that need to be solved urgently. Summary of the invention

[0003] The purpose of the embodiments of the present 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.

[0004] To solve the above technical problems, the embodiments of the present application are implemented as follows: On the one hand, an embodiment of the present application provides a communication method, which is applied to a forwarding plane UP of a broadband access server, and the method includes: In a case where the communication connection with the control plane CP is disconnected, receiving a network access request of a first user; A first network access address is allocated to the first user, and a network connection is established for the first user based on the first network access address.

DETAILED DESCRIPTION

[0014] The embodiments of the present application provide a communication method and a broadband access server device, which are used to solve the problem that a user cannot go online after a UP and CP network interruption causes the UP to be unable to process user data.

[0015] In order 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 in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0016] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein.

[0017] Figure 1is a schematic structural diagram of a vBRAS device according to an embodiment of the present application, such as Figure 1 As shown in the figure, the vBRAS device includes CP and UP. The CP and UP communicate through the CP interface protocol, including protocol interface, control interface and management interface. Among them, CP can implement user management, user access control, UP management, address management, etc., and UP can implement traffic forwarding, traffic statistics, unicast routing, multicast routing, user access control, address management, etc.

[0018] Figure 2 is a schematic flow chart of a communication method according to an embodiment of the present application, the communication method is applied to Figure 1 As shown in UP. Figure 2 As shown, the method includes the following steps S102-S104: S202: When the communication connection with the CP is disconnected, a network access request from a first user is received.

[0019] The network access request of the first user may carry the user information of the first user, and the user information may include at least one of the following: the user name, password, user name, telephone number, identity code for unique identification, etc. used by the user to access the UP.

[0020] S204: 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.

[0021] Optionally, when allocating the first network access address to the first user, the UP selects the first network access address from a preset address pool of the UP and allocates it 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-allocated to the UP.

[0022] Optionally, a plurality of network access addresses in a preset address pool are pre-allocated to the UP by the CP.

[0023] Optionally, when UP allocates a first network access address to the first user, different methods are selected to allocate the first network access address to the first user in a targeted manner according to whether the first user is a new user or a user saved in UP. Users saved in UP refer to users whose user information has been saved in UP, that is, old users who have established a network connection with UP. After UP establishes a network connection for the user, the user's network access address can be associated with the user information and stored locally in UP, for example, the user's network access address is associated with the user name and stored. In this way, after receiving the network access request of the first user, it can be determined whether the first user is a new user or a user saved in UP based on the user information of the first user carried in the network access request, so as to select a corresponding method to allocate the first network access address to the first user in a targeted manner.

[0024] In response to the first user being a new user, the UP selects a first network access address from a preset address pool and allocates it to the first user, wherein the first network access address has not been allocated to other users.

[0025] In response to the first user being a user saved in the UP, the first network access address corresponding to the first user saved in the UP is allocated to the first user. The first network access address corresponding to the first user is the first network access address stored in association with the user information of the first user. That is, in the case where the communication connection with the CP is disconnected, if the first user is a user saved in the UP, it means that the first user has established a communication connection with the UP before the communication connection between the UP and the CP is disconnected, and the first user is disconnected due to the disconnection of the communication connection between the UP and the CP. In this case, the UP allocates the network access address used by the first user when accessing before to the first user, so that the first user can quickly restore the communication connection with the UP.

[0026] In addition, if the first user is an old user, the UP may 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 the CP is disconnected, in the case where the old user requests access, the UP may not consider the network access address that the old user used when accessing the UP, but reselect a network access address from the preset address pool for allocation. The reselected network access address may be the same as or different from the network access address that the old user used.

[0027] Optionally, before the UP allocates the first network access address to the first user, it is not necessary to authenticate the first user. That is, after receiving the network access request from the first user, the UP directly allocates the first network access address to the first user.

[0028] Optionally, a fault protection period of a predetermined duration is pre-configured. During the fault protection period, the UP may perform steps S202-S204 on behalf of the CP. If the communication connection between the CP and the UP is not restored after the fault protection period, the UP may disconnect the communication connection with the first user. The predetermined duration of the fault protection period may be configured according to actual business needs.

[0029] In this embodiment, the UP may allocate the first network access address to the first user by using a DHCP (Dynamic Host Configuration Protocol) agent, that is, the UP may allocate the first network access address to the first user by using the identity of the CP agent.

[0030] By adopting the technical solution of the embodiment of the present application, when the communication connection between UP and CP is disconnected, after UP receives the network access request of the first user, it allocates the 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 can be seen that when the communication connection between UP and CP is disconnected, UP can autonomously allocate the first network access address to the first user requesting access, without interacting with CP, and without waiting for CP to come back online, so it can still ensure the normal processing of user data, effectively improve the stability of UP processing user data, and improve the user's network usage experience.

[0031] In one embodiment, after establishing a network connection for the first user based on the first network access address, the UP may perform service restrictions on the first type of service request of the first user.

[0032] The first type of service request is determined based on a preset rule. The preset rule is used to indicate the restricted service type, and may include at least one of the following: services with a service importance level higher than or equal to a specified level, and services of a specified type. If the service type corresponding to the service request meets the service type indicated by the preset rule, it is determined that the service request belongs to the first type of service request.

[0033] Optionally, a corresponding service importance level is configured in advance for each type of service, for example, the service importance level is represented by a number such as level 1, level 2, level 3, etc. The larger the number, the higher the corresponding service importance level. Assuming that the designated level is 2, if the service importance level corresponding to the service request of the first user is higher than or equal to 2, that is, a service request of level 2 or above, then the service request will be determined as a first-category service request and service restrictions will be imposed on it.

[0034] Optionally, a designated type of service is preconfigured, for example, some non-basic services are configured as designated type of services. If the service request of the first user corresponds to a designated type of service, i.e., a non-basic service, then the service request will be determined as a first type of service request and service restrictions will be imposed on it, so that only the service request of the first user for the basic service can be processed.

[0035] Optionally, performing service restriction on the first type of service request may be performed by: refusing to process the first type of service request.

[0036] In this embodiment, since the first network access address of the first user is directly allocated by the UP, the identity of the first user is unknown to the UP. By performing service restrictions on the first type of service request of the first user, the UP only processes the basic services of the first user or services with a lower service importance level, thereby ensuring continuous processing of user data and ensuring the security of service processing when the communication connection between the UP and the CP is disconnected.

[0037] In one embodiment, when the communication connection with the CP is restored, in response to the first user's identity authentication passing, the service restriction on the first type of service request of the first user is lifted. After the service restriction on the first type of service request of the first user is lifted, the UP can process the first type of service request of the first user.

[0038] Optionally, when the communication connection with the CP is restored, the CP performs identity authentication on the first user and sends the identity authentication result to the UP. The identity authentication result includes identity authentication failure or identity authentication success.

[0039] When the identity authentication of the first user is passed, the UP may actively lift the service restriction on the first type of service request of the first user, or lift the service restriction on the first type of service request of the first user after receiving a lifting instruction for the first user sent by the CP.

[0040] In this embodiment, when the identity authentication of the first user is passed, the service restriction on the first type of service request of the first user is lifted in time, so that the first user who accesses the UP during the period when the communication connection between the UP and the CP is disconnected can request to process a higher level of service after the identity authentication is passed, thereby improving the user's network usage experience.

[0041] In one embodiment, when the communication connection with the CP is restored, in response to the first user's identity authentication being successful, the user information and the first network access address of the first user are recorded in the UP.

[0042] Optionally, the UP records a user information table, which is used to record user information of users who establish a communication connection with the UP, and a network access address used when the user establishes a communication connection with the UP. The user information may include at least one of the following: a user name, password, user name, telephone number, and an identity code used for unique identification, etc., used by the user to access the UP.

[0043] When the identity authentication of the first user is passed, the UP may associate the user information of the first user with the first network access address and store it in the user information table, so that the first user is recorded as an "old user". Thus, when the first user is accessed next time, the user information of the first user can be found in the user information table, and a network connection can be established for the first user based on the first network access address associated with the user information.

[0044] In one embodiment, when the communication connection with the CP is restored, in response to the first user's identity authentication failing, the communication connection with the first user is disconnected.

[0045] Optionally, when the communication connection with the CP is restored, the CP performs identity authentication on the first user and sends the identity authentication result to the UP. The identity authentication result includes identity authentication failure or identity authentication success.

[0046] In the case that the identity authentication of the first user fails, the UP may actively disconnect the communication connection with the first user, or disconnect the communication connection with the first user after receiving a disconnection instruction for the first user sent by the CP.

[0047] In this embodiment, when the identity authentication of the first user fails, the communication connection with the first user is disconnected so that the user who fails the identity authentication can be kicked out in time, ensuring that the users communicating with the UP are all users who pass the identity authentication, thereby improving communication security.

[0048] In one embodiment, when the communication connection between UP and CP is disconnected, users who have established a network connection with UP can continue to stay online, and UP will not actively kick users offline, thereby avoiding business interruption caused by the disconnection of the communication connection between UP and CP and improving the stability of UP in processing user data.

[0049] Figure 3 is a schematic flow chart of a communication method according to an embodiment of the present application, the communication method is applied to Figure 1 As shown in the CP. Figure 3 As shown, the method includes the following steps S302-S306: S302: When the communication connection with the UP is restored, obtain user information of a first user, where the first user is connected to the UP when the communication connection between the CP and the UP is disconnected.

[0050] The user information may include at least one of the following: user name, password, address information, etc. used by the user to access the UP. The first network connection address used by the first user to connect to the UP is allocated by the UP. The first user may be a new user or an old 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 has expired. An old user refers to a user who has established a network connection with the UP and whose user information is stored in the UP.

[0051] Optionally, when the communication connection with the UP is restored, the UP actively sends the user information of the first user to the CP. Alternatively, the CP instructs the UP to send the user information of the first user, and the UP sends the user information of the first user to the CP based on the instruction of the CP.

[0052] S304: Authenticate the first user based on the user information.

[0053] The user information includes authentication information used to authenticate the identity of the first user. The authentication information may be part of or all of the user information.

[0054] Optionally, the CP pre-stores a user information table, which is used to record user information of users who have passed identity authentication. The user information may include at least one of the following: user name, password, user name, telephone number, and identity code used for unique identification when the user accesses the UP.

[0055] When the CP performs identity authentication on the first user, the user information of the first user may be compared with the user information table. If the user information of the first user is recorded in the user information table, it is determined that the identity authentication of the first user is passed. If the user information of the first user is not recorded in the user information table, it is determined that the identity authentication of the first user is not passed.

[0056] S306: In response to the identity authentication being successful, record the allocation status of the first network access address of the first user.

[0057] The allocation status is used to indicate that the first network access address has been allocated to the first user. Optionally, the CP records the allocation status of the first network access address of the first user, which can be performed in the following manner: the CP records the association relationship between the first network access address and the user information of the first user, and the association relationship indicates that the first network access address has been allocated to the first user.

[0058] In this embodiment, after the communication connection between the CP and the UP is restored and the identity authentication of the first user is passed, the CP does not need to re-allocate a new network access address for the first user, but instead records the allocation status of the first network access address allocated by the UP to the first user, so that the first user can continue to use the first network access address to communicate with the UP. This process can be called the placeholder behavior of the first network access address after the CP goes online.

[0059] By adopting the technical solution of the embodiment of the present application, when the communication connection between CP and UP is restored, the first user accessing UP is authenticated, and after the authentication is passed, the allocation status of the first network access address of the first user is recorded, thereby realizing "placeholder" of the first network access address. This "placeholder" method can not only avoid the situation where the first network access address is repeatedly allocated to other users, but also enable the first user to continue to use the first network access address to communicate with UP, without the need for CP to reallocate a new network access address after the communication connection between UP and CP is restored, thereby avoiding the situation where the first user's connection is interrupted due to the CP's re-entry, ensuring business continuity, and improving the stability of UP in processing user data.

[0060] In one embodiment, in response to the identity authentication failing, 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 who failed the identity authentication can be kicked out in time, ensuring that the users in the communication connection with the UP are all users who passed the identity authentication, thereby improving the communication security.

[0061] In one embodiment, in response to the identity authentication being passed, the CP instructs the UP to cancel the service restriction on the first user. By instructing the UP to lift the service restriction on the first type of service request of the first user, the first user who accesses the UP during the period when the communication connection between the UP and the CP is disconnected can request to process a higher level of service after the identity authentication is passed, thereby improving the user's network experience.

[0062] The communication method provided by the present application is described below through specific embodiments.

[0063] Figure 4 FIG. 1 is a schematic structural diagram of a vBRAS device according to another embodiment of the present application. Figure 4As shown, the vBRAS device includes a UP and two CPs, namely CP1 and CP2, and CP1 and CP2 are mutually hot standby protection. A communication connection between UP and at least one of CP1 and CP2 can be considered as a communication connection between UP and CP. A preset address pool and a user information table are stored in UP. The preset address pool includes multiple network access addresses pre-allocated by CP. The user information table is used to record user information of users who establish a network connection with UP, as well as the network access address used when the user establishes a network connection with UP. Figure 4 In the example, UP establishes network connections with user 1, user 2, and user 3 to forward user data for user 1, user 2, and user 3.

[0064] Among them, user 1 accessed before the communication connection between UP and CP was disconnected, and user 2 and user 3 accessed during the period when the communication connection between UP and CP was disconnected. Assume that user 1 is an old user, user 2 is a new user, and user 3 is an illegal new user. An old user refers to a user who has established a network connection with UP and whose user information is stored in UP. A new user refers to a user who has never established a network connection with UP, or a user who has established a network connection with UP but whose lease has expired. An illegal user refers to a user who has not passed the identity authentication or has not undergone identity authentication.

[0065] During the period when UP maintains a communication connection with CP, CP allocates 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 information of user 1 in the user information table.

[0066] At a certain moment, UP senses that the communication connection with CP is disconnected and enters the fault protection period. At this time, UP maintains the network connection with user 1 and continues to process the service request of user 1. Optionally, UP disconnects the network connection with user 1 after the lease period of user 1 expires. Optionally, UP does not consider the lease period of user 1 and continues to maintain the network connection with user 1.

[0067] During the fault protection period, user 2 sends a network access request to UP. UP does not find user 2's user information in the local user information table and determines that user 2 is a new user. UP does not authenticate user 2, but directly selects an unassigned network access address 2 from the local preset address pool and assigns it to user 2, and establishes a network connection for user 2 based on network access address 2.

[0068] During the fault protection period, user 3 sends a network access request to UP. UP does not find user 3's user information in the local user information table and determines that user 3 is a new user. UP does not authenticate user 3, but directly selects an unassigned network access address 3 from the local preset address pool and assigns it to user 3, and establishes a network connection for user 3 based on network access address 3.

[0069] At a certain moment later, the communication connection between CP1 and UP is restored and the fault recovery period begins. At this time, CP1 obtains the user information of the users accessed by UP during the fault protection period, including the user information of user 1, user 2, and user 3. CP1 performs identity authentication on the users accessed during the fault protection period. Optionally, CP1 compares the user information of user 1, user 2, and user 3 with the local user table of CP1 respectively. The user table is used to record the user information of users who have passed the identity authentication. Since user 1 accessed before the communication connection between UP and CP was disconnected, it means that user 1 has been authenticated by CP1 or CP2 and the identity authentication has passed. Therefore, the user information of user 1 must be recorded in the user table of CP1, and CP1 determines that the identity authentication of user 1 has passed. Since both user 2 and user 3 accessed during the period when the communication connection between UP and CP was disconnected, identity authentication was not performed when connecting to UP. Assuming that CP1 finds the user information of user 2 in the user table, but does not find the user information of user 3, it is determined that user 2 is a legal new user and user 3 is an illegal new user. Afterwards, CP1 may instruct UP to disconnect the network connection with user 3. According to the instruction of CP1, UP disconnects the network connection with user 3 and stops data forwarding of user 3.

[0070] In addition, since the network access address 2 of user 2 is allocated by UP, CP1 records the allocation status of network access address 2 after the identity authentication of user 2 is passed to indicate that network access address 2 has been allocated to user 2, thereby avoiding the network access address 2 from being repeatedly allocated to other users, and enabling user 2 to continue to use network access address 2 without having to go offline and back online, thereby ensuring the continuity of data forwarding of user 2.

[0071] It can be seen that by adopting the communication method of the embodiment of the present application, even if the communication connection between UP and CP is completely disconnected, the continuity of user data forwarding and the network access effect for new users can still be achieved. And after the communication connection between UP and CP is restored, through the "placeholder" processing of the network access address by CP, the forwarding and online access of users by UP can be kept unaffected, and the data forwarding of legitimate users (i.e. users who have passed identity authentication) can be kept uninterrupted, which greatly improves the stability of user data forwarding.

[0072] In summary, specific embodiments of the present subject matter have been described. Other embodiments are within the scope of the appended claims. In some cases, the actions recorded in the claims can be performed in a different order and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or sequential order shown to achieve the desired results. In some embodiments, multitasking and parallel processing can be advantageous.

[0073] The above is a communication method provided in an embodiment of the present application. Based on the same idea, an embodiment of the present application also provides a broadband access server device.

[0074] Figure 5 is a schematic block diagram of a broadband access server device according to an embodiment of the present application. In this embodiment, the broadband access server device is a UP. Figure 5 As shown, the UP includes: The receiving module 51 is configured to receive a network access request from a first user when the communication connection with the CP is disconnected; The network connection module 52 is configured 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.

[0075] In one embodiment, the network connection module 52 performs the following steps when allocating the first network access address to the first user: In response to the first user being a new user, selecting the first network access address from a preset address pool of the UP, and allocating the first network access address to the first user; The preset address pool includes a plurality of network access addresses, and the plurality of network access addresses are network access addresses pre-allocated to the UP.

[0076] In one embodiment, the network connection module 52 performs the following steps when allocating the first network access address to the first user: In response to the first user being a user stored in the UP, a first network access address corresponding to the first user stored in the UP is allocated to the first user.

[0077] In one embodiment, the UP further comprises: A restriction module is used to perform service restriction on 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.

[0078] In one embodiment, the UP further comprises: The disconnection module is used to disconnect the communication connection with the first user in response to the first user's identity authentication failing when the communication connection with the CP is restored.

[0079] In one embodiment, the UP further comprises: The restriction removal module is used to remove the service restriction on the first type of service request of the first user in response to the identity authentication of the first user passing when the communication connection with the CP is restored.

[0080] By adopting the technical solution of the embodiment of the present application, when the communication connection between UP and CP is disconnected, after UP receives the network access request of the first user, it allocates the 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 can be seen that when the communication connection between UP and CP is disconnected, UP can autonomously allocate the first network access address to the first user requesting access, without interacting with CP, and without waiting for CP to come back online, so it can still ensure the normal processing of user data, effectively improve the stability of UP processing user data, and improve the user's network usage experience.

[0081] Those skilled in the art should understand that Figure 5 The broadband access server device in can be used to implement the communication method applied to UP described above, and the detailed description should be similar to the description of the method part above. To avoid tediousness, it will not be repeated here.

[0082] Figure 6 is a schematic block diagram of a broadband access server device according to another embodiment of the present application. In this embodiment, the broadband access server is a CP, such as Figure 6 As shown, the CP includes: The acquisition module 61 is used to acquire user information of a first user when the communication connection with 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, configured to perform identity authentication on the first user based on the user information; The recording module 63 is configured to record the allocation status of the first network access address of the first user in response to the identity authentication being passed.

[0083] In one embodiment, the CP further comprises: An indication module is used to indicate disconnection of the communication connection with the first user in response to failure of the identity authentication; or to indicate cancellation of service restrictions on the first user in response to success of the identity authentication.

[0084] By adopting the technical solution of the embodiment of the present application, when the communication connection between CP and UP is restored, the first user accessing UP is authenticated, and after the authentication is passed, the allocation status of the first network access address of the first user is recorded, thereby realizing "placeholder" of the first network access address. This "placeholder" method can not only avoid the situation where the first network access address is repeatedly allocated to other users, but also enable the first user to continue to use the first network access address to communicate with UP, without the need for CP to reallocate a new network access address after the communication connection between UP and CP is restored, thereby avoiding the situation where the first user's connection is interrupted due to the CP's re-entry, ensuring business continuity, and improving the stability of UP in processing user data.

[0085] Those skilled in the art should understand that Figure 6 The broadband access server device in can be used to implement the communication method applied to CP described above, and the detailed description thereof should be similar to the description of the method part above, and will not be repeated here to avoid tediousness.

[0086] Based on the same idea, the embodiment of the present application also provides an electronic device, such as Figure 7 As shown. Electronics may have relatively large differences due to different configurations or performances, and may include one or more processors 701 and memory 702, and the memory 702 may store one or more storage applications or data. Among them, the memory 702 can be a short-term storage or a permanent storage.

[0088] By adopting the technical solution of the embodiment of the present application, when the communication connection between UP and CP is disconnected, after UP receives the network access request of the first user, it allocates the 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 can be seen that when the communication connection between UP and CP is disconnected, UP can autonomously allocate the first network access address to the first user requesting access, without interacting with CP, and without waiting for CP to come back online, so it can still ensure the normal processing of user data, effectively improve the stability of UP processing user data, and improve the user's network usage experience.
