Method and system for realizing 5G slice member signing and de-signing by delay queue

Abstract

The invention discloses a method and system for realizing 5G slice member signing and de-signing by a delay queue. The method comprises the following steps: S1, a producer generates data and sends the data to a dual-persistence unit; S2, the dual-persistence unit processes the received data to obtain a delay queue with target data objects; S3, a coordinator unit monitors the delay queue, analyzes the target data objects, and distributes the analyzed different target data objects to different consumers; S4, the consumers receive the analyzed target data objects and perform service processing; S5, the coordinator unit receives processing result feedback of the consumers; and S6, if updating of the target data objects fails, delay queue abnormity compensation processing is carried out. The method has the beneficial effects that through a cache and database double-writing mechanism, the problem of unreliable message persistence caused by uncontrollable memory when a memory database is directly used as a delay queue is solved.

Description

technical field [0001] The present invention relates to the field of Internet technology, in particular, to a method and a system for delaying queues to implement 5G slice member signing and de-signing. Background technique [0002] 5G service scenarios allow end users to use 5G services in a very short period (such as 5 minutes) due to temporary needs, which brings extremely high timeliness requirements for the processing of slice member signing and de-signing orders. Common solutions currently include: scheduled tasks, message delay queues, Redis-based delay queues, etc. Redis is an open source (BSD licensed) in-memory data structure storage used as a database, cache and message agent. Redis provides data structures such as strings, hashes, lists, sets, sorted collections with range queries, bitmaps, hyperlogs, geospatial indexes and streams, Redis has built-in replication, Lua scripting, LRU eviction, transactions and Different levels of disk persistence, and automatic p...

AI Technical Summary

Problems solved by technology

Timing tasks cannot execute tasks without intervals, resulting in delays; and frequent scanning of the DB will also cause serious system performance loss

[0005] 2. The problem with the message delay queue is that once the message is sent out, the expiration time of the event cannot be changed, which makes it difficult to meet business demands

[0006] 3. The problems caused by the Redis delay queue are: ①The cost of directly canceling the event is too high; ②When an accident occurs in Redis, it may cause data loss; ③When the consumer thread continuously obtains timed-out data from Redis, the consumption Or downtime or restart will also cause data loss
