Machine-to-Machine(M2M) Communication for cdma2000 Systems Orlett W. Pearson, 3GPP2 LS to TR-50 October 2010
2 | 3GPP2 M2M | October 2010 3GPP2 LS to TIA TR-50 M2M Study - Scope Identify applicable M2M communications use cases and characteristics. Identify the list of potential requirements needed to enable machine type communications on cdma2000 networks based on the identified M2M service functionalities. Identify possible enhancements that would help in providing cdma2000 network operators with lower operational complexities when offering machine-type communication services Evaluate the impact of the anticipated large number of M2M devices and how to minimize this impact on the cdma2000 networks; e.g., Group Based. Optimize network operations that can minimize the impact on device battery power usage.
3 | 3GPP2 M2M | October 2010 3GPP2 LS to TIA TR-50 3GPP2 M2M Activity 3GPP2 SC Ad Hoc on M2M Numbering and Addressing M2M Study work being developed in TSG-S Completion date: 4Q2010 Items being addressed: recognizing a potentially large number of communicating devices, lower costs and less effort, data communications (packet/circuit switch), majority of these communications involve small to little traffic TSG-X kicked off an M2M joint session with TSG-A and TSG-C (September) Introduced Network Optimizations M2M E2E Procedures Architecture
4 | 3GPP2 M2M | October 2010 3GPP2 LS to TIA TR-50 M2M Study – Characteristics Being Considered Low Mobility - M2M devices that have a limited scope of movement. Time Controlled - M2M Applications that can tolerate sending or receiving data during certain time intervals in order to avoid unnecessary signalling. Time Tolerant - M2M devices that can postpone their data transmission (load conditions). Location Specific Trigger – Used to trigger M2M devices that are known by the M2M Application to be in a particular area or location. Uplink Data for Provided Network Destination - Used with M2M Applications that require all data from a M2M device to be sent to a specific network (using IP address). Infrequent Transmission - Used with M2M devices that are expected to send or receive data with a long period of time between two data transmissions. Group Based M2M Characteristics, Group Based Policy, Group Based Addressing - A group of M2M devices which could share the same subscription and a common set of M2M characteristics can be handled by the network as a group rather than individually. Priority Access - Used with M2M devices that need to communicate information in an emergency situation, and may be related to public safety.
5 | 3GPP2 M2M | October 2010 3GPP2 LS to TIA TR-50 M2M Study – Use Cases The group is reviewing various Use Cases relative to groups. A few are noted: Smart Metering –Fixed to Low Mobility, Small Data Transmission, Time Controlled, Group- based Policy, Group-based Billing, Group-based Addressing Professional Health Care Monitoring –Low Mobility, Small Data Transmission, High Priority Fleet Management Tracking –Small Data Transmission, Mobile Device, Group-based Billing Public Safety –Priority Access, Small Data Transmission, Group-based Policy Payment Machine –Fixed or low mobility. Some payment terminals (e.g., hand-held credit card machines used in restaurants) have low mobility. Exception cases include vending machines on high-mobility transportation (e.g., trains). Group-based address & policy - The operator might want to address this type of device on a group basis.
6 | 3GPP2 M2M | October 2010 3GPP2 LS to TIA TR-50 M2M Study – Terminal Security Terminal Security: M2M devices might use detachable device such as M2M UICC with CSIM application or R-UIM to store subscription information for M2M applications. Since many M2M terminals might be installed outside and not monitored in real time, the detachable device for storing subscription information would create security issue. Develop a mechanism to prevent theft, tampering with subscription credentials and subscription information. May need to develop some special mechanism to authenticate M2M terminals.
7 | 3GPP2 M2M | October 2010 3GPP2 LS to TIA TR-50 M2M Study Battery Life Battery Life Improvement for Battery Operated M2M Devices: Many M2M devices might not need to periodically wake up to monitor the network providing an opportunity to save battery life by configuring M2M devices for different sleep duration and wakeup time. Reducing unnecessary re-transmissions of M2M application packets. Consider categorizing M2M applications (allow more transmission delay/response: Low sensitive latency Medium sensitive latency High sensitive latency
