Processing method and system for M2M terminal call

Abstract

The invention discloses processing method and system for an M2M terminal call. In the method, after being switched on and started, a plurality of M2M terminals respectively acquire respective random time and respectively carry out delay according to the respective random time; and after the delay is finished, the M2M terminals respectively establish connection with an application system by a wireless network. The processing method and system for the M2M terminal call can solve the problem of network congestion caused by the simultaneous access of a plurality of terminals in an M2M business in a calling delay way, thereby removing obstacles for providing an application service having the characteristics of strong instantaneity, small transmission flow, long-time networking, and the like for a CDMA system and simultaneously ensuring that an M2M business can be commonly developed with other businesses in a CDMA network.

Description

technical field [0001] The present invention relates to the technical field of CDMA application, and more specifically, to a method and system for processing calls of an M2M terminal. Background technique [0002] The CDMA network has the advantages of high bandwidth and stable transmission, so the CDMA technology with high-quality wireless transmission characteristics can be used for data transmission applications. With the popularization of CDMA network, users of various enterprise groups have higher and higher demands for information application services provided by various remote wireless methods (for example, information services such as vehicle positioning, power meter reading, and environmental protection and water conservancy monitoring). It is called M2M (Machine-to-Machine) business, and M2M refers to a communication form in which one or both parties are machines, and the machines can automatically complete the entire communication process through program control. ...

AI Technical Summary

Problems solved by technology

[0004] In a word, when the physical concentration of M2M terminals is too high (for example, the physical area of ​​fixed terminals is concentrated or mobile terminals converge into a certain physical area within a certain period of time) or the time of data access and transmission is also concentrated, it may affect the The impact on the communication of the cell is mainly reflected in: the exhaustion of service channel resources; the repeated calls caused by call failures consume a large amount of public control channel resources. The above problems can be collectively referred to as "network congestion caused by a large number of simultaneous access terminals in question"
