29、rastructure is a viable communication network option for the M2M 5 applications, including: 6 Identify M2M service functionalities that capture the 7 fundamentals of M2M communications and possible M2M 8 applications. 9 Identify applicable M2M communications use cases and 10 characteristics to ensur
30、e that they are the basis for the evaluated 11 network enhancements through out this study. 12 Identify the list of potential requirements needed to enable 13 machine type communications on cdma2000 networks based on 14 the identified M2M service functionalities. 15 Evaluate the impact of the antici
31、pated large number of M2M 16 devices and how to minimize this impact on the cdma2000 17 networks (e.g., a clear definition of M2M Group Based 18 communications and its usage). 19 Identify possible enhancements that would help in providing 20 cdma2000 network operators with lower operational complexi
32、ties 21 when offering machine-type communication services. 22 Optimize network operations to minimize the impact on device 23 battery power usage. 24 This study of M2M Communication is targeting the enablement of machine-25 type data communication services and M2M applications on cdma2000 26 network

36、y or course of action is discouraged but not 1 prohibited. “May” and “need not” indicate a course of action permissible within 2 the limits of the document. “Can” and “cannot” are used for statements of 3 possibility and capability, whether physical or causal. 4 1.3 References 5 All references are i

38、s internal addressing mechanism (e.g., 26 through a “Home Gateway”, or a “Data Aggregator”); 27 Through a logical mapping of pre-registered information (e.g., use 28 ATI to access an M2M device in a cell in an HRPD network). 29 S.R0141-0 v1.0 10 Although it is straightforward to have each M2M device
39、 equipped with an IP 1 address, it may not be practical due to the complexity limitation of some M2M 2 devices, such as a simple motion sensor of a security monitoring system. 3 Addressing through another subsystem is a typical solution to accommodate 4 the M2M devices with limited complexities or t
40、o shield certain M2M devices 5 from being directly accessed from the external addressing mode (e.g., through 6 direct IP access). 7 Each M2M device should be uniquely identified. Typically, an M2M device must 8 have an identifier associated with the physical identity (e.g., a serial number) 9 so tha
41、t it can be uniquely tracked for device management purposes. 10 Those M2M devices that connect directly to the cdma2000 network need a 11 subscription for a service, and hence, a subscription identity is required. The 12 subscription identity, preferably, should be uniquely associated with the M2M 1
42、3 device; however, there may be occasions the subscription identity indicates a 14 “group service”, which is applicable to a group of M2M devices. 15 In order for an M2M device to transmit data or for the network to page an M2M 16 device within a cell more efficiently, a physical identity (or a subs
43、cription identity) 17 can be mapped to a logical identity with an access ID in a shorter format. For 18 example, in cdma2000 network, the physical identity of an M2M device can be 19 mapped into a logical identity such as an Access Terminal Identifier (ATI) after 20 the M2M device has been registere
44、d with a valid subscription identity. The logical 21 identity can then be used to identify the M2M device in the same way as the 22 physical identity but in a more compact format for the transmission efficiency 23 over the air link. 24 In order to support the class of M2M devices that require end-to
45、-end IP 25 communication capability, each M2M device directly connected to the cdma2000 26 network may need to have a unique IP address. M2M devices connected to the 27 network via some type of M2M Gateway may or may not use IP addressing. 28 It is recommended that the device identity be separated f
46、rom the subscription 29 identity. Comprehensive recommendations on device numbering and 30 addressing related to the M2M subscription identity and the device identity for 31 the cdma2000 systems can be found in the SC report on this subject. 32 33 6 POTENTIAL M2M COMMUNICATION SERVICE REQUIREMENTS 3
47、4 6.1 Improved Management of M2M Communication Groups 35 M2M Service subscribers will be able to assign multiple devices that can be 36 managed on an individual or group basis. For an operator supporting M2M 37 devices on its network, it would be helpful if there is a broadcast message that 38 can b
48、e sent from the network for the purpose of controlling or alerting a group 39 of M2M devices. From the viewpoint of radio congestion, it is preferable to 40 utilize aggregate control via broadcast messaging rather than individual 41 S.R0141-0 v1.0 11 simultaneous messaging addressed to each one of t
49、he multiple M2M 1 subscribed devices. 2 M2M Services will be able to send a broadcast message to a large group of M2M 3 devices affiliated with a single subscriber (e.g., to page the M2M devices). 4 6.2 Reduced Complexity 5 There is a need for a class of M2M devices with reduced design complexity (e.g., 6 reduced radio interface design complexity due to low data transmission rate) 7 for certain M2M applications such as vending machine, Supervisory Control 8 And Data Acquisition (SCADA), electric meters, home s
