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, 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, the message terminal call delivery is implemented according to the previously cached routing information, and the cached user routing information is updated;

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

Abstract

The invention relates to a short message centre routing method for an IP multimedia subsystem and an apparatus thereof. The method comprises the following steps of: receiving messages by a short message centre; searching user routing information cached in advance according to the called user by the short message centre; if searching successfully, implementing message eventual call delivery according to the routing information cached and updating the user routing information cached; otherwise, initializing inquiry of number attribute of the called user to an ENUM server directly by the short message centre, determining the route and caching the called user routing information for use in next search; setting a time interval threshold for the routing information cached by the short message centre and timing the routing information cached; and deleting the cached routing information which exceeds the time interval threshold by the short message centre.

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:tom@def: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 Sess...
