6
feature

• modules commonly used in mobile web applications
• pictograph converter
• carrier, handset type / ID detector
• template engine
• simple, thin, easy-to-understand, light-weight
• fast XS implementations for the better
  performance
• used in large-scale mobile services for a long
  time

7
requirement

• Server
• Linux (CentOS 4.x in DeNA)
• Perl 5.8.0 or later
• Apache (1.3.x in DeNA)
• FastCGI or mod_perl (FastCGI in DeNA)
• MySQL 5.0.x
• Cellular Phone
• NTT DoCoMo FOMA
• i-mode ID / HTTPS will be supported soon
• au WIN
• Softbank Mobile 3GC

modules for mobile web applications
9
MobileEnv.pm

• MB_CARRIER_IP D, A, V, I, X, -
• MB_MODEL_TYPE DM, DF, AU, AH, VC,
  VP, VW, VG
• MB_MODEL_NAME ex. N905i
• MB_SERV_LV -1 unsupported
• MB_SERIAL, MB_SERIAL2 utn of NTT DoCoMo
• MB_UID i-mode ID, EZ number, Softbank UID
• other

10
difficulty in pictograph

• compatibility
• three carriers have their own pictograph set
• DoCoMo 252, au 822, Softbank 474
• three carriers have their own encoding and code
• only au handsets can display them from DoCoMo
  code
• users among different carriers would like to
  communicate each other with pictographs
• ? converter needed
• how to be stored in DB

11
pictograph in MobaSiF

• developers write only one template for three
  carriers with i ??? ( a pictograph input
  application for PCs, provided by NTT DoCoMo)
• users can input pictograph in ltFORMgt
• among users using a same common carrier
• exactly same pictograph can be exchanged
• among users using different carriers
• similar pictograph can be exchanged
• with our original mapping
• own encoding for DB

encoding for Softbank Mobile

• v-sjis-w Softbanks official encoding Web
  code
• 0x1B 0x24 C1 C2 0x0F ( max 5 bytes)
• v-sjis-u MobaSiFs original encoding

  carriers
• template compiler makes binary template
• 1 HTTP request ? 1 parse

• template
• loop (List)
• hname ? hprice ?! ltbrgt

18
MTemplate tags (3)

• switch by the carrier
• DOMd,v
• only for DoCoMo and SoftBank
