Method for transmitting Sh interface transparent data

Abstract

The invention discloses a method for transmitting Sh interface transparent data, which is used for transmitting subscriber data between a home subscriber server (HSS) and an application server (AS), so as to improve the transmission efficiency of the subscriber data. The method comprises the following steps: the AS sends a subscriber data operation request to the HSS, and indicates that the subscriber data is transmitted by using data segmentation transmission characteristic in a service indication region of the transparent data mentioned in the request using a service indication with a special mark; and the HSS searches the subscriber data according to the service indication with the special mark, and conducts corresponding operations on the subscriber data according to the subscriber data operation request. The method overcomes the shortcoming with the transmission of entire Sh interface subscriber data blocks in the prior art.

Description

Technical field [0001] The invention relates to a method for transmitting transparent data, in particular, to a method for transmitting transparent data on an Sh interface. Background technique [0002] IP Multimedia Core Network Subsystem (IMS) is the core of the new generation communication network. figure 1 Describes the network elements and their connections for data storage and service provision in the IMS architecture. Among them: Home Subscriber Server (HSS) 101 is the main storage server for all user and server-related data in IMS; Service Call Session Control Function (Service CSCF, S-CSCF) 102 controls the session process Core network element; Session Initiation Protocol (SIP) application server (SIP Application Server, SIP AS) 103, Open Service Access (OSA) service capability server (OSA Service Capability Server, OSA) -SCS 104 and OSA Application Server (OSA-AS) 105 are network elements that provide value-added multimedia services. [0003] The home user server 101 is...

AI Technical Summary

Problems solved by technology

For the home user server 101, which is the core network element of the IMS network, because it needs to serve a large number of users, the amount of data greatly affects the efficiency of the home user server 101 in processing data, and greatly weakens the service capability of the home user server 101

[0010] It can be seen that although the existing method of transmitting user data in blocks between the AS and the home user server 101 is relatively simple, the frequent transmission of large amounts of data obviously puts a relatively large pressure on the network bandwidth and affects the core network elements. The processing pressure is relatively high

In addition, the core network element in the IMS belongs to the user server 101, which usually needs to serve tens of thousands of users, and the entire block update of each user data also limits its service capability

[0011] From the above analysis, it can be seen that there are defects in the way of transmitting transparent data through the Sh interface in the existing IMS, the efficiency is low, and the service capability of the home user server 101 is also limited.
