Abstract

The invention discloses an RRC (Radio Resource Control) state transfer control and data transmission method, device and system. The method is that the terminal at an RRC connection state is switched the RRC alive-keeping state for keeping the connection between the terminal and the network alive according to the configuration in order to support permanent online service experience after determining that the terminal suffers from non-traditional service from the first clock starting timing time to the stopping time; if determining that the terminal at the RRC idle state receives the service request or calling for the non-traditional service or determining that the alive-keeping instruction from the terminal is received, the terminal is switched to the RRC alive keeping state. According to the scheme, the method has the advantages that a novel RRC state for keeping alive the connection between the terminal and the network according to the features such as small data quantity and sudden arrival of the non-traditional service, and therefore, the cost of connection release and switching maintenance of the terminal can be greatly reduced, and the effects of increasing the data transmission efficiency and lowering down the network burden can be achieved.

Description

A kind of RRC state transfer controls and data transmission method, equipment and system

Technical field

The present invention relates to wireless communication technology field, particularly relate to a kind of based on novel RRC(RadioResource Control, radio resource control) the RRC state transfer of state controls and data transmission method, equipment and system.

Background technology

At present; along with M2M(Machine to Machine; machine to machine) terminal, instant messaging service and always online business prevailing; cause the short burst service such as a large amount of burst small data packets business and keep-alive small data packets business, greatly change the category of Mobile solution and mobile service.

Particularly; due to for the burst short burst service such as small data packets business and keep-alive small data packets business; the beginning of session is compared the stream business such as traditional video traffic, file-sharing business or speech business and is wanted much fuzzy with interruption; packet in session is relatively so not continuous, thus causes being difficult to the interval distinguished between a clear terminal data bag and occurs within a session or occur in outside a session.And, due to current, network can be considered according to length interval time between packet to connect the need of first discharging one with the economize on electricity realizing terminal, therefore, after session and packet obfuscation, the Connection Release of mobile terminal network-oriented will from a session once to a packet once, and the data volume from a session is turned into the data volume of a packet by the data volume once connected, have again, due at LTE(Long Term Evolution, Long Term Evolution) etc. in system, one time Connection Release comprises safe activation, the processes such as the foundation of dedicated signaling and the foundation of Deta bearer, relate to more than ten Signalling exchanges, the signaling traffic load of about 256 bytes can be produced, therefore, when carrying out the transfer of data of short burst service such as burst small data packets business and keep-alive small data packets business etc., consider the features such as the little and burst arrival of data volume that short burst service possesses, the signaling consumption of unit of transfer's data obviously increases, (described data signaling is than referring to the ratio of valid data with Internet Transmission signaling to make data signaling ratio, wherein, described Internet Transmission signaling comprises the connection establishment signaling of rrc layer, hand off signaling, the resource request signaling of media access control layer and the measurement feedback signaling etc. of bottom) greatly reduce, cause the efficiency of transmission of data not high, further, terminal is for a long time in dormancy-activation, and namely Idle state-connected state two states convert back and forth, is also difficult to realize effective dormancy economize on electricity.

That is; traditional communication mode being applicable to " the network-oriented connection " of the stream business such as video traffic, file-sharing business or speech business is difficult to the transmission of the adaptive business such as emerging burst small data packets and keep-alive small data packets; by causing a large amount of signaling consumptions, cause the efficiency of transmission of data not high.For the problems referred to above, industry proposes following several possible solution:

At support MTC(Machine Type Communication, machine type communication) business aspect, depend on position relationship more stable between MTC terminal and base station and type of service, between user and network, set up the security information of acquiescence, Deta bearer information, support that the MTC small data packets reducing signaling consumption is transmitted; Or, in the heartbeat message transmission optimization supporting always online Consumer's Experience, the proxy gateway of application level is introduced in suggestion in a network, with the inner IP(Internet Protocol of maintenance terminal, procotol) and external IP semi-static/static mappings relation; Or trigger core network element by application server to maintain and the PDP context(Packet Data Protocol Context of not releasing user, block data protocol context; Or, notified the arrival of pushed information by CS territory (Circuit Switch, circuit commutative field), to reduce the always online demand of application; Or, utilizing the short burst and once or the feature of less interaction times of small data packets, by acquiescence signaling bear or NAS(Non-Access Stratum) and signaling completes small data packets transmission etc.

But; because above-mentioned each scheme all requires adaptive as far as possible existing terminal configuration; therefore; be difficult to the connection guiding attribute breaking through LTE and other existing cellular networks completely; cause the laser propagation effect for business such as emerging burst small data packets and keep-alive small data packets not good; therefore, need badly and provide a solution to solve above-mentioned each problem.
