Abstract. WAP(Wireless Application Protocol) services have become the

available method for subscribers to access mobile Internet through mobile ter-

minal anywhere and anytime. To efficiently compete in the global telecommu-

nication market, SP (Service Providers) need a unique, open, scalable and

flexible WAP Service System Architecture. A logical architecture of WAP Ser-

vice Systems based on MISC(Mobile Information Service Center) platform dis-

cussed in this paper is designed and developed on J2EE(Java 2 Enterprise Edi-

tion) architecture and deployed on BEA WebLogic Server. This system can

support multiple services, applications and contents across multiple access

wireless networks and devices, can reduce the development complexity, de-

ployment risk and help SP rapidly develop a series of diverse WAP services

and applications for the purpose of Industry perspectives and profitability

which ultimately can promote beneficial circulation of Industry Value Chain

and impulse WAP Service market to further develop.

1 Introduction

A good logical architecture of WAP Service System not only processes flexible, port-

able and scalable interfaces which make it more easier to develop various services,

but also provides rational and feasible Maintenance and Management System that can

make it more convenient to make corresponding WAP services maintenance and

management for the purpose of solving diverse problems from the system inside and

various complains from terminal users outside.

Considering the development status quo of WAP services, a kind of logical architec-

ture of WAP Service System based on MISC Platform [2] has been designed and

developed, based on which some WAP Services have also been implemented. The

practical value of this System has got validated.

In this paper, for each component in system, detail description involves its responsi-

bility and function. Besides, an amount of analysis and research to related technolo-

gies are also discussed.

2.1 MISC Platform

MISC Platform is the band and bridge between Operators and SP. As the mobile data

services platform of CMCC (China Mobile Communication Co.), it is the core of

CMCC Monternet Plan and composed of three components and three interfaces:

• MISC.CORE—the key component of Mobile Monternet Wireless Data Service

Net, with main responsibility for User Management Services Management and

SP Management and providing open common API[2](Application Programming

Interface) to outside entities (SP)and changing function to every service Gateway

and SP;

• MISC.WTBS—the proxy of user and SP to transmit services request and be in

change with data synchronization information of Service State Management;

• MISC.WAP.Portal—Monternet WAP Portal Website, integrating many SP ser-

vices.

• Interfaces between MISC and SP WAP Services System—implementation of

information transmission between MISC and SP services.

 Page invitation Interface: MISC transmits authorization information to SP

through this interface;

126

 Provision Interface: MISC sends command interaction Http/XML request

through this interface，after received this request, SP can get related pa-

rameters to make corresponding disposal;

 Service Quality Checking Interface: MISC makes timely service quality

checking to some certain applied service through this interface.

2.2 MISC WAP Solution

Fig. 2. MISC WAP Solution Scheme.

• Function Enter:

SP applies to operators for WAP Service Access by two modes: Literal Mode and

EOA [5] mode. After audit, the related materials of SP is stored by operator into their

Service Database, at the same time, MISC Platform starts up Service Test, Service

Commercial Attempt and other corresponding steps to prove the feasibility of WAP

services applied by SP, at last SP WAP services validated will be loaded on Monter-

net WAP Portal as the formal commercial services.

• Function Select:

When inviting the WAP Portal of the operators, though whose oriented function users

can query various WAP services to select some interesting things to make Service-

Subscription. When accomplished Subscription, users are noted the information about

service changing and service clause.

127

• Function Use:

After successful subscription, users can invite the subscribed service. WTBS as Ser-

vice Invitation Proxy substitutes for user to invite service, at the same time, makes

service control and management to guarantee the legal subscribed relationship.

• Function Change:

Once the subscribed service is used, MISC platform will create corresponding service

changing information to change, finally to transmit BOSS [5] (Business Operation

Support System) or SCP (Service and Content Provider) of IN [6] (Intelligent Net-

work) with responsibility of changing users.

2.3 SP WAP Services System and Key Technologies

SP WAP Services System including following three components: SP Service Layer、

SP WAP MM (Maintenance and Management) Platform and DB (Database):

• SP Service Layer: includes a series of service modules. Various wireless services

are designed and developed according to its client service request, such as News

Browse, Picture download, Weather Conditions Query, Search Engine etc.

• SP WAP MM Platform: involves a series of service logical interfaces and WAP

MM modules. Service logical interfaces as the band and bridge between SP Ser-

vice Layer and SP WAP MM Platform, which is called usually API with purpose

of helping to implement various service logical functions. SP MM modules are

designed to implement Service Management, SP WAP System Management and

Log Management, etc.

• DB: a module with responsibility for providing plenty of data resources.

This WAP Service System is designed based on J2EE architecture. The related key

technologies of this system are involved:

• SP Service Layer have many service modules, which are implemented with Serv-

let technology in which WML[1][7](Wireless Markup Language) or

XHTML[5][8](eXtensible Hypertext Markup Language) can be embedded;

• System MM platform is mainly implemented by JavaBean、JSP technologies

which can be tested on BEA WebLogic Server, while the interfaces between

WAP Services Layer and WAP MM system are adopted EJB technology which

can be directly deployed and tested on BEA WebLogic Server. Logical Interfaces

adopts EJB technology.

• As for the DB design, Oracle[10][14] has been taken into account.

The benefits of this Design:

In this WAP Service System Design based on J2EE architecture, many technologies

can be created, tested, debugged, optimized or deployed on BEA WebLogic Server,

can reduce the development complexity, deployment risk and help SP rapidly develop

a series of diverse WAP services and applications as soon as possible for the purpose

of Industry perspectives and profitability.

2.4 Typical WAP Service Flow

Figure 3 describes a typical WAP service procession.

Fig. 3. Typical WAP Service Flow.

①At first, User invites MISC.WAP.Potal;

②After received inviting request, MISC.WAP.Potal permits user authoritarian and

checks the subscribed relationship between user and the corresponding Monternet

service;

③If not subscribe this service, the user will be return to subscription page noted the

subscribed changing information;

④After confirmed the subscribed relationship by user, return user subscription suc-

cess response;

⑤User sends service visiting request to MISC;

⑥Then MISC sends inviting request to SP WAP Services System;

⑦Service Logical Module in SP WAP Service System records corresponding Logical

procession and sends Information request to SP DB;

⑧～⑩The corresponding information got from DB by Service Logical Module will

be transmit to the user by the proxy—WTBS Module MISC Platform.

3 Diversification of WAP services

Some hot WAP services includes: News Browse, Picture&Ring Download, WAP

Address, Checking Flight information, Viewing Traffic and Location information,

Checking weather conditions, WAPMail, WAP search engine, Stream Media based

129

on WAP and MBlog based on WAP and so on, some of which have been imple-

mented on our WAP Services System and put into practice.

4 Conclusion and Future Work

In this paper, the whole system is designed and developed on J2EE architecture

and deployed on BEA WebLogic server, which is a kind of optimized scheme to

not only design and development WAP services system but also other value-added

services.

This system can support multiple services, applications and contents across multi-

ple accessing wireless networks and devices, can reduce the development complex-

ity, deployment risk and help SP rapidly develop a series of diverse WAP services

and applications.

A series of diverse WAP services developed on this system has verified the imple-

mentation of this system. Given the interface, WAP services logical layer devel-

opment is the key technology that can make more and more new popular services

easier to access the WAP Service System. The flexibility, portability and scalability

of the interfaces will be a very important direction in our future research and de-

velopment.
