Introduction
Purpose and scope
This document is aimed to specify B/OSS (PortaBilling) to ZXUN USPP HSS/SPR (ZTE EPC solutions) provisioning in details enough to implement the same by interoperability parties. This document will be the base for interoperability test (IOT) afterwards.
The document includes the description of protocols used at reference points:
- Transport and application layer protocols used
- Methods to interact
- Data structure to use within methods
The document is designed to cover typical user scenarios encouraging going through use cases one by one from description level to API design level.
The other than “B/OSS to HSS/SPR provisioning” reference points (like Gy, Ga, etc) are out of scope.

Architecture Overview
LTE (Long Term Evolution) is becoming the new standard for building wireless networks. Numerous benefits in terms of radio technology (which are beyond the scope of this document) allow service providers to deploy the LTE network rapidly and at reduced cost.
PortaBilling can serve as the B/OSS system for LTE services, i.e. it manages customer data (including unified balance), service configuration details, product/rate tables, and so on for LTE just like for other services (VoIP or DSL Internet access).
PortaBilling can also provision customer data into HSS (to allow centralized user authentication across the network) and SPR (to allocate the correct package with quotas/policy/QoS parameters to the customer).
The main quota control function in this project is SPR (but not B/OSS via Gy). Gy is expected to provide usage details only in later stages of the project.
On PortaBilling side a standard Event Scripts Framework is used (triggered upon creation of a new account, product or service feature change, etc.). The data are provisioned into HSS and SPR using SOAP as a provisioning protocol.
This document is the step forward to make PortaBilling provisioning customer data to ZXUN EPC platform by ZTE.
Business Model Overview
Prepaid
Postpaid
The end-users will use LTE internet based on assigned subsription plan - reccuring charges will apply. Once there's no available funds, the user will be redirected to the portal for payment collection.
