Embodiment Construction

[0043] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0044] According to the purpose of the present invention provides IP multimedia subsystem short message center routing method, such as figure 1 As shown, the following steps are included: first, the short message center receives the message;

[0045] The short message center determines the called user of the message, and searches for the routing information of the user previously cached;

[0046] If the search is successful, implement message terminal call delivery according to the previously cached routing information, and update the cached user routing information;

[0047] If the search fails, the short message center directly inquires the ENUM server...

Abstract

A routing method for a short message center of an IP multimedia subsystem and an apparatus thereof are provided. The method includes that: the short message center receives a message; according to the called user of the message, the short message center inquires formerly buffered routing information of the user; if the inquiry is successful, final call forward is implemented according to the formerly buffered routing information and the buffered routing information of the user is updated; if the inquiry fails, the short message center directly inquires attributes of the called user number in a telephone number mapping server, determines a routing, and buffers the routing information of the called user for use in the next inquiry; the short message center sets a time interval threshold for the buffered routing information, and times the buffered routing information; and the short message center deletes the routing information buffered over the time interval threshold.

Description

technical field [0001] The invention relates to the field of IP multimedia subsystem (IMS) network short message center, in particular to a method and a device for acquiring destination user routing information in the IP multimedia subsystem. Background technique [0002] IMS network, that is, IP Multimedia Subsystem. It can handle a variety of services and is considered to be the core technology of the next generation network. At present, the SMS service is slowly moving from experimental testing to online commercial use. The main address formats are TEL URI and SIP URI. The composition of the two numbers is different. The SIP URI is like sip:tomdef:com. TEL URI is similar to tel:12345678. The SMS center needs to determine the message delivery network element based on the addresses in the two formats. [0003] The traditional method is to query the ENUM server for each message to obtain the attribute of the destination number, so as to determine which CSCF (Call Sessi...
