Description

The method and public service entity of data transmission in unified machine to machine system Technical field

The present invention relates to the communications fields, and more particularly, to the method and public service entity of data transmission in unified machine to machine system.

Background technique

The structure of unified machine to machine (one Machine to Machine, referred to as " oneM2M ") system is divided into application layer, public service layer and network layer.Wherein application layer is managed the related operation and storage for being responsible for application by application entity (Application Entity, referred to as " AE "), and include in application layer is the end-to-end oneM2M solution of instantiation.Public service layer is by public service entity (Common Services Entity, referred to as " CSE ") it manages and is responsible for convergence application layer message formation resource pool while coordinating bottom-layer network to transmit, it is that core layer in oneM2M plays the role of platform, public service layer includes a series of public service function of instantiations.Network layer, which is then managed by network service entity (Network Services Entity, referred to as " NSE "), is responsible for bottom-layer network transmission, provides the ability that bottom-layer network can provide to public service layer.

Reference point (i.e. interface) in oneM2M system between layers has 3 kinds, wherein the interface between Mca:AE and CSE, the communication being responsible between AE to CSE or CSE to AE；Interface between Mcc/Mcc ': two CSE, the communication being responsible between CSE；Interface between Mcn:CSE and NSE, the communication being responsible between CSE to NSE or NSE to CSE.There are one Mch reference points, are the interfaces between oneM2M system and charge system.

OneM2M system architecture is broadly divided into two domains: communal facility domain (Infrastructure Domain, referred to as " IN ") and local domain (Field Domain), wherein local domain includes intermediate node (Middle Node, referred to as " MN "), application service node (Application Service Node, referred to as " ASN ") and application specific node (Application Dedicated Node, referred to as " AND ").Wherein other nodes all include CSE in addition to ADN node only includes AE.

It is merged with unified machine to machine (M2M) communication system, promotion M2M global standards with vertical industry application to efficiently dispose, globalization normal structure-oneM2M comes into being.The elementary object of oneM2M is the M2M application layer standard of Unified Communication industry, promotes effectively collaboration inside communications industry.OneM2M standard uses the function structure of layering, and communication between layers is completed by unified interface, and based on unified interface, compatible different bottom accesses network to oneM2M system requirements simultaneously (including but not limited to third generation collaborative project partner (3^rdGeneration Partnership Project, referred to as " 3GPP ", Wireless Fidelity (Wireless Fidelity, referred to as " WiFi "), bluetooth (Blue Tooth)).

With the fast development of technology of Internet of things, the application scenarios that oneM2M system is covered are increasingly extensive, and business demand is more various, in many scenes, there is corresponding requirement using the service quality (Quality of Service, referred to as " QoS ") for network.Such as in traffic system, the gathering system of car accident information has higher requirements to time delay；And tele-medicine is applied and is had higher requirements to the time delay and packet loss of network.The QoS value parameter that oneM2M system needs capable support different, such as: rate, time delay, packet loss, the bit error rate, network bandwidth etc..

Existing oneM2M standard uses (the Things Like Representational State Transfer of the representative state transfer of resourceoriented, referred to as " RESTful ") framework, data transmission guarantee mechanism under OneM2M system is transmitting (<delivery>) resource and communications management (<cmdhpolicy>) strategy under joint CSE, is realized by the relevant parameter of data transmission state in change request message (request).There is no the QoS based on business transmission requirement to indicate mechanism, the mapping mechanism of QoS to bottom-layer network, end to end QoS transmission mechanism.Therefore, this data transmission guarantee mechanism can only ensure the most basic transmission requirement of data, be unable to satisfy the demand of many existing application scenarios.

At present, the relevant technologies utilize centralized resource manager and service controller, define service and its qos parameter, and internet protocol-based (Internet Protocol, referred to as " IP ") network, qos parameter is mapped as differentiated services code points (Differentiated Services Code Point, referred to as " DSCP "), the transmitting of qos parameter in network is completed by routing, to guarantee the quality of service.But in the technical solution, the transmitting of qos parameter needs are partially completed by the DSCP in IP data packet, so that the technical solution is mainly based upon 3GPP network, all bottom-layer networks that cannot well suitable for OneM2M system.

Therefore, under existing oneM2M system, how to meet the requirement using the QoS for network under different application scene, be current urgent problem to be solved.
