Abstract
The disclosed method for building subscription dialogue comprises: the subscription grid element initiates the subscription request with address as the register server to the register server; the latter receives the request and builds the subscription dialogue.
Description
Technical field
The present invention relates to the communications field, particularly relate to foundation and subscribe to the method for dialogue and the method for booking reader's incident.
Background technology
Session Initiation Protocol is the agreement that is used to set up Multimedia session of IETF RFC3261 definition.At present, Session Initiation Protocol is widely used in comprising packet networks such as Internet network, IMS network.For example the IMS network be 3GPP R5 and R6 based on the SIP framework, adopt the business network of multiple access technologies such as 3G/2G GPRS, WLAN.
In order to obtain user position information, SIP is the location-based service establishment binding relationship of special domain by registration service, and the recording address in the contact address of Contact header field and the To header field is bound in registration service.A recording address can be bound one or more contact address.When the acting server in this territory receives a SIP request, record coupling according to Request-URI in the request and recording address, the contact address of finding the user to register, it is which user's registration status information that wherein said Request-URI is used to indicate what will subscribe to.Forwarding the request to this contact address then goes.
The SIP registration service comprises by register requirement REGISTER asks to be used for increasing, to delete, refresh, inquire about binding information.REGISTER request can increase the binding between a recording address and one or more contact address.The content that client can be deleted front binding equally also can the query note address current bind address.
In RFC3265 (Session Initiation Protocol (SIP)-Specific Event Notification) and RFC3 680 (A Session Initiation Protocol (SIP) Event Package for Registrations), defined the subscribing mechanism of SIP, and the method for passing through subscribing mechanism booking reader registered events.Its main flow process is as shown in Figure 1:
