The backup method of the session message provided by the invention can be applied to the application scene shown in fig. 1A, and is realized by the UPF network element in fig. 1A, wherein the UPF network element provides a unique IP (Internet Protocol) address and port to the outside, and the UPF network element comprises a main UPF module, a standby UPF module and a backup service module; the main UPF module is used for executing the main function of the UPF network element, namely receiving and processing a session code stream based on PFCP sent by the SMF network element through an N4 interface; the backup UPF module is used for replacing the main UPF module to become a new main UPF module when the main UPF module is abnormal and executing the main function so as to ensure the high availability of the UPF network element; the backup service module is used for backing up the session message so as to ensure the integrity of the session message in the backup UPF module; after the main UPF module is started, establishing TCP (Transmission Control Protocol) connection based on Socket with the backup service module to ensure the Transmission of session messages; after the backup UPF module is started, the TCP connection based on Socket is established with the backup service module.
Example one
Fig. 1B is a flowchart of a method for backing up a session message according to an embodiment of the present invention, where this embodiment is applicable to a case where a UPF network element backs up a session message based on a PFCP, and the method may be executed by a device for backing up a session message according to an embodiment of the present invention, where the device may be implemented by software and/or hardware and integrated on a UPF network element, and the UPF network element may be integrated in a network device such as a server, a switch, or a router, and the method specifically includes the following steps:
s110, the master user port function module responds to the session message based on the message forwarding control protocol, obtains a current session key value pair according to the current session message, and sends the current session key value pair to the backup service module; wherein the key name of the current session key-value pair comprises a session endpoint identifier of the current session message.
Between SMF network element and UPF network element, transmitting data stream through session code stream based on PFCP; the PFCP-based session code stream specifically includes an mac (media Access control) address, an IP address, a UDP (User Datagram Protocol) message, and a PFCP message; and the main UPF module creates a local PFCP session message structure according to the obtained session code stream based on the PFCP, and saves the session message obtained by analyzing the session code stream in the local PFCP session message structure.
After acquiring the current session message, the main UPF module takes the session endpoint identifier of the current session message as the key name of the current session key value pair; wherein, the Session Endpoint Identifier (Session Endpoint Identifier, SEID) is data information stored in the SEID field in the Session message based on the PFCP; when a PFCP endpoint (i.e. an SMF network element in the embodiment of the present invention) sends a session message to an opposite PFCP endpoint (i.e. a UDF network element in the embodiment of the present invention), a locally-allocated SEID value needs to be used, and the SEID value is added to the session message to serve as identification information of the session message, and different PFCP session messages can be distinguished through session endpoint identification; meanwhile, after acquiring the current session message, the primary UPF module may use the current session message itself as the key value of the current session key value pair.
Optionally, in this embodiment of the present invention, the acquiring, by the master user port functional module, the current session key value pair according to the current session message includes: the master user port functional module acquires the session type of the current session message according to the message type identifier of the current session message; if the session type is session creation, the master user port functional module takes the current session message as a key value of a current session key value pair; if the session type is session modification, the master user port functional module acquires a matched historical session message according to the session endpoint identifier of the current session message, and acquires a key value of a current session key value pair according to the historical session message and the current session message; and if the session type is session deletion, the master user port functional module sets the key value of the current session key value pair to be null.
Specifically, the Type identifier is data information stored in a Message Type field in a session Message based on the PFCP, and reflects a session Type of the session Message, for example, when the Type identifier is "1", "2", and "3", the session Type is session creation, session modification, and session deletion, respectively; creating a session, namely creating a new session message; session modification, namely modifying the existing session message; deleting the session, namely deleting the existing session message; if the session type is session creation, it indicates that there is no history information of the current session message in the local session message, so that the session message itself is directly used as the key value of the current session key value pair; if the session type is session modification, which indicates that the history information of the current session message exists in the local session message, because the session modification is the modification performed on the history information, the current session message may not include the complete session content itself, but only include the session content of the part to be modified, for example, the session message is "create a character string ABCDEFG" when being created, and the current session message is "replace the initial letter with M", thereby obtaining the history session message matched with the current session message according to the session endpoint identifier, obtaining the modified complete session content together according to the history session message and the current session message, and using the modified session content as the key value of the current session key value pair to ensure the completeness of the session content in the key value of each session key value pair; and if the session type is session deletion, setting the key value of the current session key value pair to be null so as to reduce the data transmission quantity between the primary UPF module and the backup service module.
S120, the backup service module adds the current session key value pair into a ring queue, and performs session integration on the session key value pair in the ring queue according to a preset trigger condition; wherein the session integration comprises session merging and/or session deletion.
The ring queue is an ordered list based on an array, and follows the principle of first-in first-out, namely, firstly stored data is taken out firstly, then stored data is taken out later, and an offset is added when each message is stored; the main UPF module stores each session key value pair in a sequential writing mode, and the standby UPF module takes out each session key value pair in a sequential reading mode. When the backup service module integrates the session key value pairs in the ring-shaped queue, if the primary UPF module does not acquire the session type, the primary UPF module directly takes the acquired session message as a key value, the backup service module needs to determine the execution result of the key value according to the key values of all the session key value pairs under the key name, takes the execution result as the key value of the target session key value pair with the key name added time closest to the current moment, and sets an invalid mark for other session key value pairs under the key name, so that the backup UPF module is started in a delayed manner, or after the backup UPF module is restarted, the session key value pair with the invalid mark cannot be read when the session message is read, that is, the backup UPF module only reads the key value of the target session key value pair under the key name, the reading efficiency of the backup UPF module is improved, and the occupation of access resources of the backup UPF module is reduced.
For example, a key name includes 3 session key value pairs stored in sequence, the key values of the 3 session key value pairs are "create a character string ABCDEFG", "modify an initial letter to M", and modify a tail letter to N ", obviously, the execution result of the key values is" acquire a character string mbcdeffn ", the" acquire character string mbcdeffn "is set as the key value of the 3 rd session key value pair, and invalid marks are set for both the 1 st session key value pair and the 2 nd session key value pair, when the UPF module performs session key value pair reading, the 1 st session key value pair and the 2 nd session key value pair will not be read, but the session key value pair with the invalid marks still occupies the original memory space; if the key name also comprises a 4 th conversation key value pair which is stored in sequence, and the key value is null, invalid marks are set for the 1 st conversation key value pair, the 2 nd conversation key value pair and the 3 rd conversation key value pair, when the conversation is deleted, the 4 th conversation key value pair with the null key value, the 1 st conversation key value pair with the invalid marks, the 2 nd conversation key value pair and the 3 rd conversation key value pair are deleted, and the deleted conversation key value pair does not occupy the memory space.
Particularly, as described in the above technical solution, if the primary UPF module has obtained the key values in different manners according to different session types, that is, according to different session types, the current session message is used as the key value, or the current session key value pair is obtained according to the historical session message and the current session message, or the key value is set to null, it is obvious that the key values obtained in the above manner already include complete session content, and therefore, the key value of the session key value pair whose adding time is closest to the current time under the same key name is the session result under the key name; for example, a key name includes 3 session key value pairs stored in sequence, the key values of the 3 session key value pairs are "create string ABCDEFG", "acquire string MBCDEFG" and "acquire string MBCDEFN" in sequence, when the session key value pairs are merged, an invalid flag is set for both the 1 st session key value pair and the 2 nd session key value pair, and the UPF module only reads the key value of the 3 rd session key value pair; if the key name also comprises a 4 th conversation key value pair stored in sequence, and the key value is null, invalid marks are set for the 1 st conversation key value pair, the 2 nd conversation key value pair and the 3 rd conversation key value pair, and when the conversation is deleted, the 4 th conversation key value pair with null key value, the 1 st conversation key value pair with invalid marks, the 2 nd conversation key value pair and the 3 rd conversation key value pair are deleted.
Optionally, in an embodiment of the present invention, the method further includes: the method further comprises the following steps: the backup service module acquires a leading backup service unit in a plurality of backup service units through a zookeeper management unit; the adding, by the backup service module, the current session key-value pair to a ring queue specifically includes: and the backup service module adds the current session key value pair into the annular queue of the leading backup service unit and synchronizes the current session key value pair to other backup service units through the leading backup service unit.
Specifically, the Zookeeper is a distributed application program coordination service of a distributed open source code, and provides a consistency service for distributed application; the backup service module interacts election messages of each backup service unit through a Zookeeper management unit, in the Zookeeper management unit, a backup service unit successfully created by a node is used as a leading backup service unit (namely, Leader), other backup service units are used as auxiliary backup service units (namely, follow), and the IP address and the port of the Leader are recorded through the Zookeeper management unit; when the Leader is down, selecting a new Leader based on an election mechanism among all Followers, and creating a node of the new Leader on the Zookeeper management unit; the Leader is mainly used for backing up the PFCP-based session messages sent by the UPF, and the follow is used for ensuring high availability of the backup service. After acquiring the session key value pair sent by the main UPF module, the backup service module adds the session key value pair to a ring queue of a Leader, and then synchronizes the session key value pair to a Follower in a real-time sending mode through the Leader, or synchronizes the session key value pair to the Follower in a batch sending mode so as to reduce the performance loss of the backup service module; in fig. 1C, the backup service module includes three backup service units as an example.
Optionally, in this embodiment of the present invention, the performing, by the backup service module, session integration on the session key value pair in the ring queue according to a preset trigger condition includes: according to preset merging conditions, carrying out session merging on the session key value pairs in the annular queue; the preset merging condition comprises a preset merging period and/or a preset merging threshold; and/or according to a preset deleting condition, deleting the session key value pair in the annular queue; the preset deleting condition comprises a preset deleting period and/or a preset deleting threshold.
The backup service module can execute session integration operation according to a preset period, namely, the session key value pairs in the annular queue are integrated at intervals of fixed time length, and can also integrate the session key value pairs in the annular queue according to a preset threshold value, namely, after the session key value pairs of the preset threshold value are added in the annular queue; the method comprises the steps of merging, namely replacing a session key value pair stored firstly with a session key value pair stored later, setting an invalid mark for the replaced session key value pair, and enabling subsequent consumers (namely UPF modules) not to read the session key value pair with the invalid mark; deleting, namely, storing the conversation key value pair later to cover the process of the conversation key value pair stored firstly, deleting the covered current conversation key value pair from the annular queue, and deleting the conversation key value pair stored later from the annular queue because the key value is empty; particularly, in the embodiment of the present invention, the preset deletion period is greater than the preset merge period, and the preset deletion threshold is greater than the preset merge threshold.
Optionally, in this embodiment of the present invention, the performing session integration on the session key-value pairs in the ring queue further includes: and according to the adding time of the conversation key value pair in the annular queue, carrying out conversation integration on the inactive conversation key value pair in the annular queue. The inactive session key-value pair refers to a session key-value pair with a joining time greater than a preset time threshold from the current time, and the active session key-value pair refers to a session key-value pair with a joining time less than or equal to the preset time threshold from the current time, that is, the inactive session key-value pair has been substantially joined to the ring queue for a long time, and usually the session operations related thereto have been completed, while the active session key-value pair may have subsequent session operations due to the late joining time, so that session integration is performed only on the inactive session key-value pair to reduce the number of session key-value pairs to be processed, and improve the integration efficiency of the session key-value pairs in the ring queue.
S130, the standby user port function module reads the key value of the session key value pair in the annular queue.
According to the technical scheme provided by the embodiment of the invention, the main user port functional module acquires the session key value pair according to the acquired session message based on the message forwarding control protocol, and sends the session key value pair to the backup service module, the backup service module adds the session key value pair into the annular queue, and carries out session integration on the session key value pair in the annular queue according to the preset trigger condition, so that the data volume of the session message to be backed up in the annular queue is greatly reduced, meanwhile, the standby user port functional module can quickly read the session message in the annular queue after the startup delay or downtime restart occurs, the backup efficiency of the session message is improved, and the occupation of access resources of the standby user port functional module is also reduced.
