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.

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.

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.

• 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.
