4. USSD Overview June 14, 2012 cdma2000 Technology Workshop 广州 Slide 4 USSD is a real-time circuit-switched communication service that is used to send text between a mobile device (either the subscriber or an application on the device) and an application program in the network. –Means that if information is not delivered immediately, it won’t get delivered later. For example: recipient’s phone is out of range or recipient’s phone is turned off. Note there are implementation workarounds to offset this issue. Three main types of USSD sessions: –Mobile initiated session –Network initiated session –Network notification.

6. USSD Mobile Initiated Banking Request: Subscriber Point of View June 14, 2012 cdma2000 Technology Workshop 广州 Slide 6 1. Subscriber initiate a USSD call to Mobile Banking Application -- *85# (Application) 2. Subscriber receives welcome message and menu from the USSD server asking for the inputs, to which subscriber responds with option 1 – Checking Account Balance 3. Subscriber receives the Checking Account Balance. Subscriber pressed 2 to exit the application. 4) Subscriber receives a thank you message for using the service. *85# 1) Checking Account Balance 2) Saving Account Balance 3) Money Transfer 4) Exit Welcome to The Bank of CDMA Menu Answer Cancel Checking Account Balance is 245,000,000 RMB Answer Cancel Thank you for using the Bank of CDMA Answer Cancel 1) For more options 2) For Exit CancelAnswer

9. Location Based Services (LBS) – Two Types June 14, 2012 cdma2000 Technology Workshop 广州 Slide 9 –Control Plane Architecture Core Network / IS-41 Network changes defined in J-STD-036 (E911) and PN-4747 / IS-881 (Value Added Services) A1 interface defined in A.S0013/ A.S0014 Air Interface changes defined in IS-801-1. Also defines application layer protocol between MS and PDE J-STD-036 and PN-4747 / IS-881 specify the core network mechanisms to obtain and deliver location information to a requesting application –User Plane Architecture- exist as a result of several issues with the control plane J-STD-036 only address E911 IS-881/X.S0002 only supports network resident applications –No support of self-location - Position can only be delivered to application server, not the MS –No support of assistance data download From in implementation viewpoint, most CDMA operators use a variant of the V1/V2 standards, built upon 3GPP2 standards, available from CDG.

15. SMS Solutions June 14, 2012 cdma2000 Technology Workshop 广州 Slide 15 Three types of solutions: –Solution 1 (Legacy Solution): Sender and the receiver have a CDMA C.S0015 client and are connected to 1xCS access networks. –Solution 2 (Transport Level Mapping): Sender has a CDMA C.S0015 client and has successfully IMS registered while the receiver has a CDMA C.S0015 client and is connected to 1xCS access network or vise versa. –Solution 3 (Application Level Mapping): Sender uses an Instant Messaging client and the receiver has a CDMA C.S0015 client and is connected to 1xCS access network or vise versa.
