  4. USSD Overview • 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. cdma2000 Technology Workshop 广州

  6. USSD Mobile Initiated Banking Request: Subscriber Point of View Welcome to The Bank of CDMA Menu Checking Account Balance is 245,000,000 RMB Thank you for using the Bank of CDMA 1) Checking Account Balance 2) Saving Account Balance 3) Money Transfer 4) Exit *85# • 1) For more options • 2) For Exit Answer Cancel Answer Answer Cancel Cancel Answer Cancel 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. cdma2000 Technology Workshop 广州

  9. Location Based Services (LBS) – Two Types • 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.

  10. Control Plane Network Reference Model Mobile Position Center (MPC) LCS Application Server L1 defined in IS-881 E3 A1 E2 defined in J-STD-036 Base Station MS E12 MSC / BSC E5 • LCS application servers always invoke MPC to request MS position • Position always delivered to application server via the MPC, not the MS Position Determination Entity (PDE) June 14, 2012 cdma2000 Technology Workshop 广州 Slide 10

  13. User Plane Network Initiated - Trusted Call Flow Trusted – No MPC interaction required • Applications send MT SMS directly to MS • MS reports position back to application either via MO SMS or MO IP June 14, 2012 cdma2000 Technology Workshop 广州 Slide 13

  15. SMS Solutions • 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.
