Problems solved by technology

[0007] Embodiments of the present invention provide a user data query method and device based on an IMS network, which solves the problem that using the existing user data query method, the intercommunication of voice services between an IMS user and a non-IMS user in a different place can only be done by "going out of the IMS network at the nearest Far into the IMS network" routing method leads to low utilization of the IMS network and high pressure on the PSTN network. It is possible to adopt the routing method of "going out of the IMS network nearby and entering the IMS network far away" and "going out of the IMS network as far as possible and entering the IMS network nearby". Network" routing method, maximize the use of IMS network, reduce the bearing pressure of PSTN network, which is conducive to the evolution and development of the network

Embodiment 1

[0053] Figure 4 It is a schematic structural diagram of the network system provided by the embodiment of the present invention. see Figure 4 , the network system includes a primary ENUM server 101 , one or more secondary ENUM servers 102 connected to the primary ENUM server 101 , and one or multiple network element devices 103 connected to the secondary ENUM server 102 . The first-level ENUM server 101, the second-level ENUM server 102, and the network element device 103 are respectively connected through a network.

[0054] In order to solve the problem of adopting the existing user data query method, when IMS users communicate with remote non-IMS users for voice services, they can only use the routing method of "going out of the IMS network at the nearest location and entering the IMS network at the far end", resulting in pressure on the PSTN network. large, low utilization of the IMS network, the embodiment of the present invention adds a data area in ENUM servers at al...

Embodiment 2

[0133] The embodiment of the present invention provides a server 1, such as Figure 10 shown, including:

[0134] The receiving unit 10 is configured to receive the query request sent by the call processing device, the query request includes the number of the called user and a tag, and the tag is used to instruct the server to query the data area of ​​the user data.

[0135] The processing unit 11 is configured to query the user data of the called user in the data area indicated by the label according to the number of the called user received by the receiving unit 10, and obtain the query of the user data As a result, the query result is used to characterize the routing mode adopted by the network to which the server belongs.

[0136] The sending unit 12 is configured to send the query result acquired by the processing unit 11 to the call processing apparatus.

[0137] Further, as Figure 11 As shown, the server 1 also includes a storage unit 13,

[0138] The storage unit ...

Abstract

The embodiment of the invention provides a user data query method and device based on the IMS network and relates to the communication field. A routing mode of 'proximal-out IMS network and far-in IMS network' and a routing mode of 'far-out IMS network and proximal-in IMS network' are adopted, so that the IMS network is made use of to the maximum extent, and bearing pressure of the PSTN network is reduced. The user data query method comprises the steps of receiving a query request transmitted by a call processing device through a server, wherein the query request comprises a number and a label of a called party, and the label is used for indicating a data area of user data inquired by the server; inquiring the user data of the called party in the data area indicated by the label according to the number of the called party, and acquiring a query result of the user data, wherein the query result is used for representing the routing mode adopted in the network to which the server belongs; transmitting the query result to the call processing device.

Description

technical field [0001] The invention relates to the communication field, in particular to an IMS network-based user data query method and device. Background technique [0002] With the continuous progress of communication technology and the continuous improvement of user requirements, the network architecture that can provide high-quality voice and video and other multimedia services is gradually becoming a hot spot in the development of communication networks. 3GPP (Third Generation Partnership Project, Third Generation Partnership Project) proposed IMS (Internet Protocol Multimedia Subsystem, IP Multimedia Subsystem) in its R5 (Release5) version, in order to provide richer multimedia services. [0003] In the IMS network, the ENUM (Telephone Number Mapping, telephone number mapping) server can complete the conversion of the E.164 telephone number of the IMS user to the SIP URI (Session Initiation Protocol Uniform Resource Identifier, the general resource identifier of the ...
