Method for integral controlling subscribe

Abstract

This invention discloses a method for controlling subscription in concentration including: a subscriber and an informer set a subscription management set between them and corresponding dialog, in which, the informer receives related information about the current subscription to judge if the information is sent by the subscriber, if so, it registers a subscribing example ID corresponding to the current in its management set to release the current subscription and its dialog, at the same time, the informer triggers the subscriber to execute it and registers the ID and releases the current subscription and corresponding dialog.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method for centralized control of subscriptions between the same subscriber and notifier. Background technique [0002] Session Initiation Protocol (Session Initiation Protocol, SIP) is a text-based application layer control protocol, independent of the underlying protocol, used to establish, modify and terminate two-party or multi-party multimedia sessions on the IP network. [0003] SIP implements the subscription / notification framework, and introduces the SUBSCRIBE method and the NOTIFY method. The SUBSCRIBE method is used by the subscriber to initiate a subscription to the notifier, and the NOTIFY method is used to communicate any change notification of an event between the subscriber and the notifier. The so-called subscription notification means that a user or resource, as a subscriber, initiates a subscription to the owner of other resources, that is, the notifier, an...

Problems solved by technology

In this way, if different subscriptions are controlled separately, that is, sessions are established separately and different sessions are managed and maintained separately, the number of SIP sessions that need to be maintained by the server as the subscriber and the notifier will be greatly increased. The business load of the terminal reduces the processing efficiency of the server

In addition, the increase in the number of conversations will occupy too much bandwidth resources of the network

[0010] Although the existing protocol proposes that different subscriptions between the same subscriber and notifier can be associated with one session for centralized control, there is currently no way to associate different subscriptions between the same subscriber and notifier with one session.
