Method and system for interworking SCCP signaling of indoor type UMTS network

Abstract

The invention discloses a system for the SCCP signaling interworking of an indoor UMTS network, which comprises an AP and an AG; a control plane protocol stack adopted between the AP and the AG is IP / SCTP / SPUA / RANAP; the SPUA is SCTP user adaptation layer protocol; an Iu interface is adopted between the AG and a CN; an SPUA signaling message is adopted to carry out interaction between the SPUA ofthe AP and the SPUA of the AG; an SCCP primitive is adopted to carry out interaction between the SPUA of the AG and the SCCP of the AG; an SCCP signaling message is adopted to carry out interaction between the SCCP of the AG and the SCCP of the CN; the SPUA of the AG carries out the inter-conversion between the SPUA signaling message and the SCCP primitive. The invention also discloses a method for the SCCP signaling interworking of the indoor UMTS network and a device thereof.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for SCCP signaling intercommunication of an indoor UMTS network. Background technique [0002] At present, the third-generation mobile communication (3G) network has been applied in some parts of the world, but due to the high frequency band of 3G application, poor penetration, and indoor coverage problems, many mainstream telecom operators have proposed indoor UMTS (Universal Mobile Telecommunications System, universal mobile communication system) solution requirements. The network logic structure under the existing indoor UMTS architecture is as follows: figure 1 As shown, the main equipment of the indoor UMTS solution includes UMTSAccess Point (UMTS Access Point, hereinafter referred to as AP) and UMTS Access Gateway (UMTS Access Gateway, hereinafter referred to as AG), and the AP equipment mainly includes base station NodeB and wireless network con...

AI Technical Summary

Problems solved by technology

The routing function of M3UA and SCCP is redundant for AP and AG, which adds unnecessary complexity and processing overhead

In addition, a signaling point needs to be allocated to each AP. Due to the huge number of APs, this will consume huge point code resources

[0021] 3) M3UA and SCCP consume a lot of memory and CPU, and the number of APs that can be connected to the AG side is very large (such as tens of thousands of APs), and the link between the AP and the AG is highly dynamic

In this way, the performance overhead of AG in maintaining the links of all connected APs will be very huge, even unbearable
