Embodiment

Inventor notices during invention：

The flow for the transition between states supported at present is：

But it is as follows some other special state to be also present：

The SOT state of termination newly introduced：Sluggish connected state (inactive state), allow in this condition as follows Behavior：

- core net sees that the UE is in connection status；

- mobility is that UE is performed, and in the pre-configured RAN tracing areas of network side, is performed by cell reselection, and It is not that handoff procedure is carried out；

The unique subscriber identification in the pre-configured RAN tracing areas of network side is assigned in-terminal.

Under Inactive states, network side is that effective RAN marks, the mark are used in terminal distribution certain area Identification terminal under inactive states, it can be used for network side and search when terminal or terminal actively initiate multi-upstream access with mark work Enter connected state for identification.Inactive UE ID are properly termed as, are referred to as resume UE ID.The mark is different In globally unique IMSI (International Mobile Subscriber Identity, international mobile subscriber identification code) Or connected state terminal iidentification C-RNTI, the identification length fall between (such as inactive UE ID length is 40bit, C-RNTI length is 16bit), only in the certain area comprising multiple cells or multiple eNB effectively, if it exceeds the region, Terminal needs to update inactive UE ID.

In the existing SOT state of termination, except RRC connected states are assigned with terminal air interface transmission unique mark C-RNTI and establish Corresponding DRB can directly carry out data transmit-receive, and when other states have upstream data to need transmission, terminal will first initiate connection and build It is vertical, into RRC connected states, RRC connections are established, establish DRB, follow-up data transfer could be carried out.

However, with the development of wireless communication system, terminal type and type of service variation, saving power for terminal, net is saved Network resource and meet the needs of miscellaneous service type and deposit.Such as it is above-mentioned, in order to ensure that saving power for terminal and rapid data pass simultaneously It is defeated, a kind of SOT state of termination inactive states are introduced, terminal keeps core net connection under this state, but without connected state of eating dishes without rice or wine Routine operation (such as switching, up timing renewal, radio link monitoring), do not distribute the terminal mark for being directly used in air interface transmission Know (such as C-RNTI), therefore be introduced into RRC connected states as above-mentioned, established RRC connections, obtain mark, progress subsequent data transmission Flow then can not directly carry out air-interface scheduling transmission.

It can be seen that above-mentioned be introduced into RRC connected states, establish RRC connections, obtain mark, carry out the flow of subsequent data transmission Process is unfavorable for having quick transmission during data arrival, and if only burst small data packets need to send, such as typical MTC (Machine Type Communication, machine type communication) business, after terminal has sent out a small data packets into connected state In order to which power saving enters idle or inactive states again, this transition between states can cause signaling consumption, if terminal quantity is huge When (such as mMTC, massive MTC scenes), this signaling consumption is almost unacceptable.

Based on this, will solve how rapid data transmission is carried out under inactive states in the embodiment of the present invention.Tie below Accompanying drawing is closed to illustrate the embodiment of the present invention.

Illustrated with example, in declarative procedure, by the DRB that is established by acquiescence by preset configuration, retained below DRB, SRB2, SRB1 classification are illustrated, and transmitting uplink datas of the UE to core net will be first illustrated in each classification Implement, the then implementation to the downlink data transmission of core net to UE illustrates.

Embodiment 1：

The present embodiment is the scheme carried out data transmission using acquiescence DRB.

First, uplink.

After UE enters the Inactive states of power saving due to long-term sent without data, if UE removes it The coverage of anchor base stations, it is attached at present under new serving BS.

If now UE has upstream data to need to send, it can be as follows：

1st, UE has upstream data to need to send, and for UE firstly the need of judging, whether Current Serving BTS is its anchor Base station, if other base stations outside anchor base stations, then UE needs newly to establish acquiescence a DRB, the DRB for upstream data ID to be pre-configured, and the relevant configuration of 1 layer 2 of related layers of DRB is also all that pre-configured good, pre-configured mode can be as Under：

(1) provided using standard, a kind of mode is to provide a set of acquiescence DRB configurations and ID, all UE with standard All business all use the configuration and ID, or are the UE type stateds of different business/different different allocation list and ID List, selected by UE according to oneself type and class of business, the mode of selection can be standardization；

UE enters before inactive states, is configured by network side dedicated signaling, can be a set of configuration and ID, for institute There are business or more set configurations and ID, different according to type of service different choice, selection mode can be taken simultaneously in configuration Band.

(2) other modes, such as the notice of Current Serving BTS, or UE signing informations regulation etc. are used.

2nd, when sending the data to current serving BS using DRB, the state variable of layer two is opened from initial value Begin.

Specifically, UE carries out the transmission of business datum using the DRB of the acquiescence, because this is a newly-established DRB, its The various state variables of layer two are since initial value such as 0.Transmission means can be that UE request network sides give special money Source, or sent on up competitive resource, UE needs to carry the inactive ID of oneself in up information；That is, When using the DRB by preset configuration foundation to send the data to current serving BS, can further include：

Notify base station UE inactive ID..

Specifically, implementation can have a lot, such as it can carry UE's in the up information of transmission Inactive ID, ID is carried with first uplink information, after both sides confirm identity, may subsequently be interacted with other ID, also may be used To be continuing with the ID.

3rd, for network side, when the data and inactive ID that receive UE, Current Serving BTS knows that this is one The UE of individual inactive states, if acquiescence DRB configuration Current Serving BTS is known, such as standard regulation or current Base station configures, then Current Serving BTS can directly establish the data that a corresponding DRB is used to handle the UE, if it is not known that Then can be to UE anchor base station requests UE context data, to obtain relevant information.

In specific implementation, the id information and part UE id informations of anchor base stations are carried in UE inactive ID, Therefore Current Serving BTS can accurately find anchor base stations, and further get UE information, it is necessary to obtain UE information mainly has：

The DRB established by preset configuration configuration information, specifically, acquiescence DRB configurations, if acquiescence DRB information takes Business base station is unclear, then needs to obtain relevant configuration to anchor base stations；

UE security-related parameters information, specifically, the safety-related contents of UE, if open safety such as encrypt, it is necessary to Security parameter is obtained such as key and AES；

Core net carrying information corresponding to UE related services, specifically, the core corresponding to UE related services is net loaded Information, such as SGW (Serving Gateway, gateway) information, duct size information, such as EPS (Evolved Packet System, evolved packet system) TEID (Tunnel End Point Identifier, Tunnel End Point Identifier) corresponding to carrying Deng.

After Current Serving BTS obtains UE information, UE data can be handled, and then UE information is issued Corresponding core network user face node, or UE anchor base stations, subsequent transmission is carried out by it.Namely：

One kind is that serving BS obtains detailed UE information, parses UE data by serving BS, is transmitted directly to core net section Point；

UE bottom data is transmitted directly to anchor base stations by another kind, serving BS, and it is parsed by anchor base stations After be sent to core net node.

2nd, downlink transfer.

If inactive UE have downlink data to need to send, it can be as follows：

For core net, it thinks that inactive UE are attached under anchor base stations, therefore the data of the UE can be first Anchor base stations are sent to, then anchor base stations can initiate the paging to the UE, obtain UE Current Serving BTSs address, UE downlink datas are sent to UE Current Serving BTSs by anchor base stations, while can carry some UE contextual information, up and down Literary information can include：

DRB configurations are given tacit consent to, if acquiescence DRB is not by standard regulation or serving BS regulation, but by anchor Decided through consultation between base station and UE, then need to transmit the information, otherwise need not；

The safety-related contents of UE, safety such as encryption is opened if desired, it is necessary to obtain security parameter such as key and add Close algorithm etc.；

After Current Serving BTS obtains UE information and data, to give tacit consent to DRB configuration, its lower line number is sent to UE According to.

UE receives the downlink data, is handled with the acquiescence DRB appointed configuration, parses user data, hair It is sent to high level.

In implementation, when the DRB by being established by preset configuration sends data, this DRB established ID and last time The DRB deleted after foundation ID is different.

Specifically, taking the newly-built DRB of acquiescence if necessary to up-downgoing data to UE to send, and start safety, Then each DRB ID needs difference.Such as DRB 0-29 are ID sections used in normal connected state DRB.And DRB30-100 To give tacit consent to DRB section used in inactive states UE, then when UE sends data for the first time, DRB30, this data are used After being sent, the DRB is deleted.Use next time, it is necessary to using DRB31, the like.

Embodiment 2：

The present embodiment is to correspond to the scheme that DRB carries out data transmission using business.

First, uplink.

If now UE has upstream data to need to send, it can be as follows：

UE has upstream data to need to send, then UE directly selects the DRB corresponding to the business to be transmitted；

UE enters after inactive, and the DRB of UE connected states is likely to be what is all retained before, because business does not have Terminate, therefore DRB corresponding to business all retains.Also or, for a long time without data, before inactive is entered, only retain One of DRB or several DRB, and the mapping ruler of business to DRB is carried out to certain configuration, if a DRB, Then all data of UE both map to the DRB, if the possible priority of several DRB is different with configuration, can configure and which characteristic met Data be mapped on high priority or the DRB of high configuration, remaining business is mapped to low priority or the DRB of low configuration On.

Easily know, UE enters before Inactive, is determined by network side, UE and anchor base stations can all retain certain DRB is configured and entity, and DRB and the mapping ruler of business, both sides are synchronous on these DRB state.

Said for network side UE Current Serving BTSs, when the data and inactive ID that receive UE, Current Serving BTS It is the UE of an inactive state to know this, if Current Serving BTS is exactly UE anchor base stations just, is also retained There are UE whole DRB information, UE data can be now configured to handle with related DRB, pass to core network user afterwards Face entity.If Current Serving BTS is not UE anchor base stations, Current Serving BTS is needed UE bottom data It is sent to the processing of anchor base stations, or the information to the anchor base station requests UE.

The id information and part UE id informations of anchor base stations, therefore current service are carried in UE inactive ID Base station can accurately find anchor base stations, and further find UE information, it is necessary to which the UE information obtained can have：

Related DRB configurations and status information, UE send DRB configuration used in data and all transmission states letter Breath, such as the value of transmission variables；

The safety-related contents of UE, if opening safety such as encryption, it is necessary to obtain security parameter such as key and encryption Algorithm etc.；

Core net carrying information corresponding to UE related services, such as SGW information, duct size information is (corresponding to EPS carryings TEID etc.).

After Current Serving BTS obtains UE information, UE data can be handled, and then UE information is issued Corresponding core network user face node, subsequent transmission is carried out by it.

UE can update original state variable information in the transmission of Current Serving BTS, because retaining the feelings of carrying , it is necessary to first obtain UE current state variable information under condition, increase in the information and update, complete after transmitting, it is also necessary to Update and store UE last states to anchor base station.So it can further include：Using the radio bearer transmissions number retained According to when, to anchor base station renewal factor data transmission and change original state variable information.

Specifically, for example, if SN is have sent before AM (Acknowledged Mode, affirmation mode), UE (Sequence Number, sequence number) is 1-5 data, can currently send the data that SN is 6, and current data send and will taken The mode of timely feedback acknowledgment, such as P bit are carried in last packet, it is desirable to all data this time sent are entered Row confirms, may be incorporated into L2 signalling interactive process, ensures that both sides know that this data is sent and are over, and all confirm It is properly received.

In implementation, one of following processing or its combination can further include：

When PDCP layers are handled, the SN and/or Count obtained from anchor base station is continuously safeguarded；

When the layer for ensureing transmission is handled, transmission state when entering inactive states is resetted；

When the layer for ensureing transmission is handled, transmission state is resetted after each the data transfer ends；

When the layer for ensureing transmission is handled, transmission state is resetted after serving BS is changed.

Specifically, the layer due to being responsible for safety, such as PDCP, for security consideration, its SN needs continuous, i.e. UE is entering When entering inactive states, PDCP Count (counting) value is 500, then Count values of subsequently giving out a contract for a project are continuously increased, continuous to safeguard. And other are simply to ensure that the layer of transmission, such as RLC and MAC, its state can be resetted every time, such as Inactive UE , it is necessary to send data during in serving BS 1, serving BS 1 is different from anchor base stations, then RLC state variables are taken from first Initial value starts, such as 0, this is sent, and RLC equities end confirms that all data are successfully transmitted and is properly received, then rlc layer pair Deng between end RLC can be resetted with Signalling exchange, again since initial value, such as 0.Or when UE has come new service base Stand, then reset RLC.

In addition, changing base station refers to that UE is moved to other base stations, situation when serving BS changes.

2nd, downlink transfer.

If inactive UE have downlink data to need to send, it can be as follows：

For core net, it is believed that inactive UE are attached under anchor base stations, therefore the data of the UE can first be sent out Anchor base stations are sent to, then anchor base stations can initiate the paging to UE, obtain UE Current Serving BTSs address, UE downlink datas are sent to UE Current Serving BTSs by anchor base stations, while can carry some UE contextual information, may Including：

Data Radio Bearer configures and status information, the Data Radio Bearer should be that data are wirelessly held corresponding to business Carry；

After Current Serving BTS obtains UE information and data, with the configuration of Data Radio Bearer and state variable, to UE sends its downlink data.

UE receives the downlink data, is handled, parsed with the configuration and state variable of related data radio bearer User data, it is sent to high level.

In implementation, it can further include：

After the data transfer ends, the mode of the signaling of layer two is taken to carry out explicit reset processing.If need to certain A little layers are transmitted the reset of end, then can take the mode of the signaling of layer two, carry out explicit reset processing.

In implementation, it can further include：

When UE is in business corresponding to initiation on the Data Radio Bearer that the anchor base station of the UE is retained, using continuous Safe floor state variable, other layers of state variable is every time since initial value.UE is every for a period of time, the business initiated again, Its safe floor state variable is continuous, and the state variable of other layers is every time since initial value.

In implementation, it can further include：

Safe floor state variable is notified to the anchor base station of the UE.

In specific implementation, UE using original DRB configurations and state variable corresponding to the business, complete it is this time up/under Capable transmission.It should be noted that this time transmitting, continuous safe floor will necessarily be especially needed to the value of state variable The value of state variable updated, such as safe floor count values increase 505 by original 500, it is meant that new 5 packets are have sent, because the state variable of safe floor is to need continuously, therefore after service ending, current service base Needs of standing notify the updated value for maintaining continuous state variable to give anchor base stations.Anchor base stations, which can store, updates the change Amount.When next UE needs to send data, count values start counting up from 506.The storage of continuous state variable can be twocouese , such as network side, its record it is descending be sent to 505, uplink receiving to 302 etc..Other layers of state variable, such as Fruit is to have resetted, then need not notify anchor base stations, and next time is since initial value, if other layers are also in need continuous State variable, then it is also required to notice and gives anchor base stations.

Embodiment 3：
