Description
Technical field
The present invention relates to wireless communication technology, relate in particular to a kind of synchronous method of discontinuous receiving cycle, system and equipment (comprising access network equipment and subscriber equipment).
Background technology
Machine to machine (M2M, Machine to Machine) communication refers to all communication technologys and the means that connect between machine.M2M communication theory has just occurred in eighties of last century the nineties, but has only rested on theory stage.After 2000, along with the development of mobile communication technology, the networking that realizes machinery equipment with mobile communication technology becomes possibility.Within 2002, left and right M2M business just occurs on market, and developing rapidly for several years subsequently, becomes the focus of numerous communication equipment Shang He telecom operators.The machine quantity in the whole world is much more a lot of than people's quantity at present, therefore can predict the good market prospects of M2M technology.
To M2M communications applications scene, research shows to provide M2M communication to have market potential prospect on mobile network.But M2M business has proposed a lot of new requirements to system, in order to strengthen mobile network's competitiveness in this respect, be necessary existing mobile network to be optimized, more effectively to support M2M communication.
Existing mobile communications network designs mainly for person to person's communication, and to machine and machine, deficiency is optimized in man-machine communication.In addition, how operator can provide M2M communication service with low cost, is also the key that success is disposed in M2M communication.
Based on above situation, be necessary to study the solution that mobile network supports M2M communication, solution should be reused existing network to greatest extent, to reduce impact that a large amount of M2M communication causes network and the complexity of operation maintenance.
At present telecommunication market competition is growing more intense, and rate constantly decline, and operator's profit margin constantly reduces, and with the Communications Market on artificial basis, is just being tending towards saturated, and M2MDui operator is brand-new opportunity to develop.
In order to effectively utilize mobile network resource, third generation partner program (3GPP, 3rd Generation Partnership Project) machine type communication (MTC has been proposed, Machine Type Communication), be that machine is to machine (Machine to Machine), the business that machine carries out communication to people (Machine to Man), its scope of business is far beyond Human To Human (H2H in the past, Human to Human) communication between, MTC is in access control, charging, fail safe, service quality (QoS, Quality of Service), the aspects such as business model and present H2H communication mode make a big difference.
