End-End IMS R7 based network design for hyrbid network
Abstract:
HSC worked with a greenfield operator which wanted to deploy an all IP IMS R7 based architecture for enabling next generation services. HSC consultants led the design and specification of this network. Some of the areas involved:
Create network design
Create RFI based on network design and invite different vendors to respond
Evaluate RFI responses and interview vendors on technology fitment
Create gap analysis of areas which were not technically ready for all IP rollout

CPE Agent Development
Key Technologies : TR 069, TR 098, TR 106, TR 104, SOAP, HTTP.
Abstract:
The need was to develop a CPE agent compliant to TR-069 and TR-098 specifications for management by ACS. CPE agent was required to facilitate management of TR-069 based accessible parameters (TR-106) and support data model for provisioning of a voice-over-IP (VoIP) CPE device (TR-104).
A CPE agent was developed in compliance to TR 069, TR 104 and TR 106 specifications.
Salient features of the CPE Agent are follows:
Initial CPE configuration,
Re-provisioning at any subsequent time,
Vendor-specific configurations.
Status and performance monitoring of the CPE.
File download initiation, dynamic notifications.
The solution supports:
All mandatory Events Notifications.
All mandatory SOAP based RPC support.
HTTP message exchange between CPE and ACS Server using Secured Transport (SSL 3.0 /TLS 1.0) and X.509 certificate verifications.
Customer Benefits:
Specification based agent allows for extensible and flexible design.
Many companies and operators have adopted TR-069.
