1 INTRODUCTION
With the network bandwidth increasing, the internet
technology evolving, the user diversified and the
rapid growth of individual needs, telecommunication
services are suffering from a strong unprecedented
impact. The internet businesses emerge in endlessly,
which is full of aggressiveness, leading the
telecommunication industry to a pretty passive
situation; the whole network concept of
telecommunication business and the standard
process aiming at obtaining a large scale of
industrialization, make the development of new
telecom services very complex, research and
development cycle very long. Consequently, it
cannot compete with the internet business (Wuwei,
2010).
Thus, service integration and capacity open are
the best means to break the barriers of network at
this stage. On one hand, it realizes the telecom
capacity to the internet, and provides
telecommunication service a new scenario; on the
other hand, a large number of business developers
and service providers are brought into the
telecommunication industry chain, attaining win-win
interests, and bringing new development
opportunities for the chain.
2 THE CURRENT SITUATION OF
DOMESTIC AND OVERSEAS
DEVELOPMENT
2.1 The Current Open Status of the
Telecommunication Services
Since the 1990s in the 20th century, the Open status
of the Telecommunication Services has become the
focus of attention of operators. France Telecom (FT)
raised the Orange Partner program in May 2004,
which is a global partner program supported by a
variety of third-parties, including over 60,000
members. In2008, Telefonic proposed wIMS2.0
program which is based on the fusion of
communication network and IMS, committing to
provide web2.0 IMS abilities, with the introduction
of web2.0 services to enrich their own
telecommunication services. Betavine is an open
community and a resource website created by
Vodafone, in order to support and promote new
applications in mobile and Internet communication
developments. The website allows developers to
upload their applications, and provides the channels
in which members can share knowledge, provide
feedback and mutual discussion. In 2009, AT & T
proposed the dev Central and Apps Beta program,
which allows developers to utilize its API to develop

new applications, and was tested with the help of
users of wireless operators. Developers can get
feedback from users to improve their own
applications. China Mobile's WIMS is the ecological
environment in which communication network
capability is integrated into Web2.0, implementing
the integration and mashups of communication
services and Internet business, thus promoting the
rapid development of new business applications (Lei
Ming, 2009).
However, the capacity open of
telecommunication services is still in its infancy.
Considering either the development of open
technology, or the mode of operation, it is not quite
mature at present.
2.2 The Current Open Status of
Internet Service
Open, sharing, free of charge have always been the
main impetus of booming development of Internet.
Compared with telecommunication networks, the
opening up of Internet service has made
considerable progress. The open of Google Maps
API, is the inception of promoting the opening up of
Internet. Following closely, Yahoo!, Microsoft
released its own open API, expecting to enhance its
own user stickiness in forms of embedding the third-
party applications. With the leading of Google,
Yahoo, Microsoft, Flickr, Youtube and other
websites also release their open API to their own
services for third-party developers one after another.
In an environment with open API, we can reorganize
some fragments of the original data, making it more
associated. Considering the poor interoperability of
different Internet service platforms, the users usually
visit different service platforms in order to obtain
various Internet services. On May 24, 2007,
Facebook launched an open platform. Using this
framework, the third-party software developers can
develop the applications integrated with the core
function of Facebook (JeffyWong, 2008).
How to integrate the Internet capacity and
telecommunication capacity rapidly and efficiently,
and implement the reopen of the ability after the
fusion, has become a issue worthy of exploring.
3 THE ARCHITECTURE DESIGN
OF CONVERGENT SERVICE
DELIVERY PLATFORM
3.1 Overview of Service Capacity Open
System
"Service capacity open system" conducted a research
from two aspects in depth, naming the network side
open capacity and mobile terminal capacity, and
established a “network side open service system”
and “terminal side open service operation
environment” accordingly, creating the
comprehensive and three-dimensional integrated
solution of “network to terminal” for the opening -
up of mobile Internet capacity.
Figure 3-1: A service capacity open system.
The network side Open service system achieved
the opening up of fusion capacity of Internet
services and telecommunication services, set up the
open architecture based on the entire service life
cycle in the "network side", including the extraction
of capacity (Kristofer Kimbler, 2007), the open
service and the final management and integration.
This chapter first proposed the two crucial criterion
of mobile Internet open services, vertical open
standards and horizontal integration standards; With
these two standards, the author outlined the location
and main functions of the open service system at
network side further; Finally, the author introduce
the Realization mechanism of corresponding
modules in each level of this system architecture in
details, meanwhile, each level can interact with each
other through some certain ways, Thus
implementing the Expansibility and maintainability

of open service system and building a
Standardization system for open service capacity at
mobile Internet “network side”.
3.2 The Architecture of Convergent
Service Delivery Platform
Convergent service delivery platform is an important
part of the network side of "service capability open
system ",It is based on open infrastructure ,and
realize the scalable, distributed, efficient, open
architecture , support large-scale service delivery,
and use the open and flexible "cloud storage" and
"cloud deployment" function to achieve the
management and support of the entire life cycle of
service. Its main functions include:
 To achieve the rapid provision of services,
deployment, implementation and operation of the
dimensional ecosystems;
 To achieve the rapid discovery and integration of
Service supply and demand;
 To open to continuous polymerization,
continuously growing and developing business
scale;
 To achieve network independence and device
independence of service;
 To implement the aggregation of mass data
resources and accurate capture of multi-dimensional
users demands;
 To realize the visit of convergent service
capacity security through the powerful Cluster
effect.
The overall architecture of convergent service
delivery platform was shown in Figure 3-2,
including the following modules:
Release Delivery Center. Service delivery platform
is mainly related to four kinds of roles, "service
users, service providers, third-party developers and
platform managers", mainly managing three types of
objects, naming applications (which is directly
available services), process (ie, services which need
redevelopment) and Supply. Release delivery
centers mainly realize the management function of
four kinds of roles and the release and delivery
function of three kinds of objects on the platform. Of
which:
- User management functions are mainly related to
basic user information management, user behavior
statistics, the capture of user demands and the
service delivery to users, etc.;
Application management, process management and
supply and demand management realized the entire
life cycle management of four flows, naming
"application flow, process flow, supply and demand
flow, user flow", and achieved the visible
monitoring of business process with the use of
BPEL (Business Process Execution Language)
engine.

Business Deployment Environment. Business
deployment environment adopts the distributed
cluster to achieve the fusion at multi business level
and the dynamic migration for business. Through the
standardized business engine mapping to various
network protocols, providing the capacity to connect
with a variety of networks, you can create
applications independent from the network in this
type of network abstraction, enabling different
networks to provide the same service. The supported
services include the traditional SOAP Web Services,
RESTful Web Services, SOA Web Services and
local telecommunication interface. SOAP Service
Interface adapter supports the application interfaces
based on Parlay X 2.1/3.0, and the expansion of
Web Service (EWS) for those does not support those
interface in Parlay X. SOA Service Interface adapter
is deployed in the service bus, and application
interface exposed by the interface adapter is
identical with that of the SOAP Service. Restful
Service Interface Adapter expose the HTTP-based
interface with JSON-based data types, so that Web
2.0 and rich Internet applications (RIA) can easily
integrate communication capabilities.Disaster
recovery controller is mainly realizing backup
support, error control, power off and other disaster
management functions in the process of service
deployment. As for the phenomenon that multiple
services are simultaneously deployed on the same
server, you need to set the load balance mechanism
to achieve cluster collaboration in the case of
existing large quantity of deployment.
Business Execution Engine. Business execution
engine includes the process execution engine and the
application execution engine, and each type of
engine includes one or more business execution
environments, such as the standard Java EE
Application Servers (usually with real-time Java
virtual machine) and telecom specific business
Platforms.
Business execution environment achieves the
implementation of all business management capacity
sets, specifically including: service application
managements such as layout, activation, cancellation
and configuration as well as other services like fault
management, redundancy management.
Operation Support System. Convergent service
delivery platform learn from the mature experience
of Telecommunication level operation support
system providing a complete set of service
operations management functions, and establishing a
strong support guarantee for the platform. Including:
the business process managements (using the SOA
mechanism) associated with the service
provisioning, implementation, operation,
maintenance etc; The implement of accounting
management with the rules of Dynamic
configuration based on the service characteristics,
while achieving the uniform of Authorization,
Authentication and Accounting (AAA); With large
operating information, the use of data mining
technology, and operation auditing functions,
providing operation status consulting of the reliable
services for service providers and platform
operators; With Concentrated log data management,
implementing the real-time security monitoring
function for early warning and safe condition.
Distributed Data Clusters. In order to prevent
business interruption caused by a single point of
failure, provide the availability and reliability of
services, achieve the integration of business
resources, enhance the comprehensive service and
achieve user value, we need to create a user
centered, distributed data cluster. So that we can
bring together the application, process, basic supply
and demand, and basic user management data, as
well as deployment, implementation and operation
data in the convergent service delivery platform. At
the same time, with massive data mining techniques,
convergent service delivery platform builds a
powerful knowledgebase, and use the intelligent
machine learning, to achieve the comprehensive
analysis from four dimensions, "application, process,
supply and demand, user". Consequently, it
enhances the novelty of the business design, the
initiative of service delivery, the accuracy of
advertising service and the rationality of network
planning, and then makes the transition from
"extensive marketing "to" precise marketing".
4 IMPLEMENTATION OF
CONVERGENT SERVICE
DELIVERY PLATFORM
Convergent service delivery platform adopts the
architecture mentioned above, polymerizing three
management objects: process, application, supply
and demand, Catering to four kinds of users
(ordinary users, third-party developers, service
providers, and platform administrators), and
providing the supervision of management,
deployment, implementation and operation of the
full life cycle. We will show the concrete
implementation of the platform from the following
three aspects, and specifically they are the business

process, the specific function and network topology
from the platform.
4.1 Business Process Instructions
In the process of implementing convergent service
delivery platform, we considered four kinds of users
involved in the platform, which is the ordinary users,
third-party developers, service providers, and
platform administrators, and followed process
retroactive characteristics. Starting with the coarse-
grained analysis of the system, the author unfolded
the business demands Step by step, and combined
with three management objects, that is "process,
applications, supply and demand". Finally, he
determined the authority and function division of
each type of user in the platform, and then obtained
the use cases view of the platform.
Four business processes are involved in
convergent service delivery platform, and they are
Application Lifecycle Management, Process
Lifecycle Management, Supply and demand
lifecycle management and Audit process
management. They are specifically shown in the
form of timing diagram:
Application Lifecycle Management(as is shown
in Figure 4-1) mainly involves a set of application
dealing processes including the application inquires ,
read of application list, application chosen, purchase
confirmation and application download ,all of which
the ordinary users conducted when dealing with the
applications on SDP.
Figure 4-1: Application Sequence Diagram.
Process lifecycle management (Figure 4-2) is
mainly related to two types of roles: the third-party
developers and service providers. The third-party
developers need to accomplish the functions, such as
the process submission, the check of process, and
the online exchanges with service providers, etc.
Service providers need to accomplish the functions,
such as the query process, the selection process, the
obtainment of process information, and the
communication with open person, purchase
confirmation, process download, and evaluation
process, etc.
Supply and demand lifecycle management is
mainly related to two types of roles: the third-party
developers and service providers. Service providers
need to accomplish the functions, such as the
submission demands, inquires demands, inquires
responses, the developers qualifications inquires,
online communication with developers, developer
confirmation, project download, developer
evaluation, etc. The developers need to accomplish
the functions, such as inquires demands, responses
demands, online communication with service
providers, project submission, etc.
Audit process management (as is shown in
Figure 4-4) mainly refers to the process that
platform administrator conducts the inquiries and
audit process as for the submitted application,
process and requirements.
4.2 Specific Function Instructions
Convergent service delivery platform can be divided
into four plates, that is application, process,
requirement, and community (shown in Figure 4-5),
making it quickly and clearly to find the target
satisfying the personalized needs for different roles
of users, which increases the friendliness of the
platform.
Application, process and requirement can be
divided into four subdivisions according to different
categories: Life Information, Amusement &
Recreation, Business & Office, Development Tool
(as is shown in Figure 4-6).
Community plate is mainly intended to provide
an exchange site for various types of users in the
platform. In this plate, a number of forums are set,
and each topic can be dynamically set on multiple
topics. Consequently, social networking groups are
formed with one topic as the centre.
