Cross reference

The present invention claims following priority: number 62/544,094, and the applying date is on August 11st, 2017, entitled " UE The U.S. Provisional Patent Application of Autonomous Release for Internet of Things ".Above-mentioned U.S. Patent application It is described herein by reference.

Technical field

The present invention relates generally to wireless communication systems.More particularly it relates to automatic Connection Release function Machine type user equipment (user equipment, UE).

Background technique

3GPP (third generation partner program) long term evolution (LTE) system provides simple network framework bring peak Value Data rate, low latency, improved power system capacity and low operating cost.3GPP LTE system additionally provides and older network Seamless integration-, such as global system for mobile communications (GSM), CDMA (CDMA) and Universal Mobile Communication System (UMTS). In view of enhancing LTE system, the reversed multitask enhancing (IMA-Advanced) forth generation (4G) of ATM can be met or exceeded Standard.One of them key enhance technology system support up to 100 megahertzs bandwidth and backward with existing Radio Network System It is compatible.In LTE/LTE-A system, Evolved Universal Terrestrial Radio Access Network (evolved universal terrestrial Radio access network, E-UTRAN) include with it is multiple be known as UE mobile communications multiple evolution Node-B (eNB)。

In general, each UE needs periodically to measure the received signal quality of serving cell and adjacent cell and ties measurement Fruit reports the eNB serviced to it potentially to be switched or cell reselection.The measurement may exhaust the energy of battery.In order to The low consumption of battery is kept, UE needs switch between sleep and wake-up states.It is preferred that being in RRC connection mode UE be possible to the operation of the sleep-awake using similar RRC idle mode, to obtain similar battery consumption.For energy conservation, Need short using wakeup time, sleep cycle length discontinuous reception (Discontinuous in connection mode Reception, DRX).It is extended by DRX, UE can be configured with longer RRC connection mode DRX cycle.

UE mode conversion between connection mode and idle mode introduces signaling overheads.To reduce this expense, UE One section of given time of connection mode (that is, active) is maintained at before discharging by the order of RRC Connection Release.However, due to even The DRX cycle connect in mode is shorter, even if transmitting without data, UE can also consume more energy in connection mode.It is existing The problem of technology is that after upper primary data transmission, UE has to wait for RRC Connection Release order and sends it to idle mould Formula.If data volume is small, this mechanism can not only introduce signaling overheads, can also be maintained at connection mode in UE and wait RRC connection Energy is consumed when release command.

For only transmitting the UE of low volume data (for example, machine type communication (MTC) and narrowband Internet of Things (NB-IoT) every time Device) for, it needs to avoid such expense.If UE can quickly discharge after upper primary transmission, it is able to enter RRC Idle or inactive mode and application and reduces power consumption at longer DRX cycle.In addition, if RRC Connection Release can be by UE is automatically performed without RRC Connection Release order, and signaling overheads can then further decrease.

Summary of the invention

The method that RRC is connected is discharged automatically with the UE of signaling overheads the invention proposes a kind of for reducing power consumption.It is sending out After sending the given incremental data with respective request and configuration process, allow to send the UE with macrocyclic low volume data, For example, machine type communication (MTC) and narrowband Internet of Things (NB-IoT) UE, automatically discharge.

In one embodiment, UE sends wireless heterogeneous networks (radio resource control, RRC) even to base station Request message is connect to establish connection within a wireless communication network.UE receives RRC connection from base station and establishes message, and the RRC is built Vertical message includes that UE discharges information automatically.UE sends the RRC connection setup complete message of subsidiary upstream data to base station.UE is in number According to starting inactivity timer after the completion of sending and receiving.When the inactivity timer time-out kept by UE, UE is released based on RRC It puts information and automatically discharges RRC connection.

In another embodiment, base station receives wireless heterogeneous networks (radio resource control, RRC) from UE Connection request message to establish connection within a wireless communication network.Base station (base station, BS) sends RRC connection foundation and disappears Breath, and when acquisition UE discharges request automatically, it includes that UE discharges information automatically which, which establishes message,.BS receives subsidiary uplink The RRC connection setup complete message of data.After UE data send or receive completion, BS starting discharges not automatically for UE Active time.RRC release information when BS is based on inactivity timer time-out determines whether UE is in RRC idle state.

Specific embodiment

Now with detailed reference to the embodiment of the present invention, its example is shown in the drawings.

Fig. 1 describes the wireless money of the UE in 4G/5G network 100 with the automatic release function of UE according to novel aspect Source controls (radio resource control, RRC) connection and establishes and discharge process.In LTE/LTE-A system, evolution is logical With grounding wireless access network (evolved universal terrestrial radio access network, E-UTRAN) Including multiple be known as evolution Node-B (eNB) with multiple mobile communications for being known as UE (for example, UE 102) (for example, BS 101) base station.In next-generation 5G system, base station is referred to as gNB.ENB and gNB is referred to as base station (BS).

In general, each UE needs periodically to measure the received signal quality of serving cell and adjacent cell and ties measurement Fruit reports the BS serviced to it to carry out potential cell reselection or switching.The measurement may exhaust the energy of battery.In order to Energy conservation needs all to use discontinuous reception (Discontinuous in both of which in RRC idle connect with RRC Reception, DRX).At the beginning, UE 102 is resided in cell and is rested on RRC idle mode.For data transmission, UE 102 need to establish RRC with BS 101 and connect and enter RRC connection mode.Between RRC connection mode and RRC idle mode Mode conversion introduces signaling overheads.To reduce this expense, UE is being discharged into the free time (that is, non-live by RRC release command Jump) connection (that is, enlivening) one section of given time of mode is maintained at before mode.However, due to the DRX cycle in connection mode compared with Short, even if transmitting without data, UE can also consume more energy in connection mode.

Problem of the prior art is that after upper primary data transmission, UE, which has to wait for the order of RRC Connection Release, can just be returned Return to idle mode.If data volume is small, this mechanism can not only introduce signaling overheads, can also be maintained at connection mode etc. in UE Energy is consumed when RRC Connection Release order.According to a novel aspect, the machine type of low volume data is only transmitted for connecting every time For the UE of type (for example, MTC, NB-IoT), need to avoid such expense.If UE can be after upper primary transmission quickly Release, it is able to enter RRC free time or inactive mode and applies longer DRX cycle and reduce power consumption.In addition, if RRC release can be automatically performed without RRC release command, and signaling overheads can then further decrease.

In the example of fig. 1, a kind of automatic method for releasing of novel UE is proposed, is had in MTC and NB-IoT UE transmission Power consumption and signaling overheads are reduced when macrocyclic low volume data.Specifically, if UE is only sent to fixed low volume data, allow it Automatic release after data transmission has completed, without clearly being ordered by network by RRC release message 130.To enable UE It is discharged automatically in MTC environment and other NB-IoT communication systems, UE 102 sends automatic release via RRC connection request 110 Request.BS 101, which sends to carry, establishes message 120 for the RRC of the UE necessary information discharged automatically, and by UE and network side Inactivity timer operation coordinated between them, to promote the automatic releasing mechanism of UE.

Description method " connection request " is intended to include following embodiment herein: " request is established in connection " is in idle mode UE request its movement to initiate data or the received connection of message related to calls, and " recovery request ", i.e., in inactive mode UE request restores the connection previously hung up.Description method " RRC connection foundation " or only " RRC foundation " are used to indicate that herein network will UE is from idle or inactive mode to being sent to connection mode.In addition, for the UE for only sending low volume data, RRC establishment process It also indicates UE and executes automatic release under certain conditions, for example, completing the transmission of data-oriented amount, or sending release auxiliary When instruction.Description method " inactivity timer " is used for the timer for indicating to start after the data transfer is complete, and when its time-out When, it is believed that UE enters idle or inactive mode.Timer is remained inactive for respectively in network side and the side UE.In the present invention, " being discharged into the free time " further includes when UE is transformed into the inactive mode of RRC or RRC light weight connection mode (RRC light Connected mode) when the case where, i.e., when UE is transformed into any situation using the ambulant mode based on UE, for example, Cell reselection.

Fig. 2 is the simplified block diagram according to the UE for discharging RRC connection automatically of novel aspect.UE 201 has memory 202, processor 203 and radio frequency (radio frequency, RF) transceiver module 206.RF transceiver 204 is couple to antenna 205 On, RF signal is received from antenna 207, RF signal is converted into baseband signal, is then forwarded to processor 203.RF transceiver 204 The baseband signal received from processor is also converted, RF signal is converted baseband signals into, is then forwarded to antenna 205.Processing The baseband signal that the processing of device 203 receives, and different functional modules is called to execute the feature in UE 201.Memory 202 store the data executed by processor and program instruction 210 to control the operation of UE 201.Suitable processor includes example Such as, dedicated purpose processor, digital signal processor (digital signal processor, DSP), multi-microprocessor, One or more and the associated microprocessor of DSP core, controller, microcontroller, specific integrated circuit (application Specific integrated circuits, ASIC), field programmable gate arrays (field programmable gate Array, FPGA) circuit and other types integrated circuit or/state machine.Processor associated with software can be used to realize and match Set the feature of UE 201.

UE 201 further includes the multifunction module and circuit that different task is executed in embodiment according to the present invention.The function Module can by hardware, firmware, or combinations thereof realize and configuration.In one example, mobile management module (mobility Management module) it 220 further comprise some functional modules and circuit.Measuring configuration module 206 is received from network and is surveyed Amount and report configuration simultaneously correspondingly configure its surveying range and reporting standards.Connect processing circuit 207 execute cell selection or again Choosing, connection is established or gravity treatment, and switching such as UE resides in or be connected to the process of serving cell.Discontinuous reception 208 use of (discontinuous reception, DRX) module is executed from the received corresponding DRX parameter configuration UE 201 of network DRX operation.Moving condition module 209 enables UE to grasp accordingly by configuring and self estimating determining UE moving condition It executes under operation mode to enhance power consumption.

Fig. 3 describe the RRC connection discharged automatically according to the support UE of novel aspect establish and the message flow of release the One embodiment.In step 311, UE 301 is via random access channel (random-access channel, RACH) to BS 302 send lead code to start RACH process (MSG1).In step 312, UE 301 is from 302 receiving random access response of BS (random-access response, RAR) (MSG2).When UE 301 has the upstream data of network to be sent to, it will usually Start RACH process.If UE 301 is MTC or NB-IoT device, the upstream data amount of transmission can be very small.If UE 301 When knowing that it only sends a data, UE can after transmitting uplink data completion informing network it want to enter into it is idle or non- Active mode.This can be completed by introducing indicating bit in RRC connection foundation or recovery request message (MSG3), in data Amount and power headroom reporting (PHR) (data volume and power headroom report, DPR) middle data indicated are transmitted Request UE discharges automatically after complete.Therefore, in step 313, UE 301 sends RRC connection foundation or recovery request to BS 302 Message (MSG3).The connection foundation or recovery request include that UE discharges request and DPR automatically, in the data volume quilt indicated by DPR Request UE discharges automatically after transmission.

In a step 314, RRC connection is established or is restored response (MSG4) and is sent back to UE 301 by BS 302, including RRC discharges information and inactivity timer value.In current system, network is detected by the inactivity timer maintained by network UE's is inactive, and when inactivity timer time-out, is sent UE to by RRC connection release message idle or inactive Mode.If UE is allowed to automatically enter RRC free time or inactive mode, it is inactive fixed all to run in network and the side UE When device.The inactivity timer value is determined by network and is UE configuration.By the way that response (MSG4) is established or restored via RRC connection Inactivity timer value is configured, network, which further acknowledges, allows UE to discharge automatically.The inactivity timer instruction of zero it is upper it is primary on It is released immediately after row transmission.In addition, network can be by including that inactivity timer value is automatic to refuse UE not in MSG4 Release request.

As UE discharges automatically, it is convenient to omit RRC connection release message.However, RRC connection release message not only sends out UE Send the information for also carrying to idle/inactive mode and such as restoring mark (identity, ID) and redirection information.Therefore, exist When UE discharges automatically, it is necessary to send this type of information to UE using different modes.A kind of simple mode is built using RRC It is vertical/to restore response message (MSG4).Specific alternative embodiment of the invention assumes that RRC foundation/recovery and RRC release message can be with It sends, such as in identical transport block, or almost together, and is released UE together since inactivity timer can be configured It is put into the free time, UE will not work to RRC release message before inactivity timer time-out.

In step 315, UE 301 is established to the RRC connection that BS 302 sends subsidiary upstream data or is restored to complete message (MSG5).Due to depth covering and data volume, the transmission of upstream data is possibly can not be by establishing in RRC connection or restoring to complete Subsidiary single transmission is completed in message.As long as UE can be in upstream data however, UE knows that it only sends a upstream data Via RRC connection request (MSG3) informing network, it wants to enter into idle or inactive mode after being transmitted.It note that logical It crosses and indicates that automatic release request is optional step of the invention using MSG3.Alternatively, UE can be requested in MAC (media interviews control System, media access control) layer discharges automatically, as existing or new MAC CE (MAC control element, MAC Control element) a part.The present invention can also work in the case where no UE is requested, for example, base station can also be from Core network obtains the information that UE discharges request automatically.

UE 301 starts inactivity timer after upper primary transmission.When inactivity timer time-out, 301 meeting of UE It is automatically discharged into idle or inactive mode (step 321), without receiving clear and independent RRC Connection Release from BS 302. BS 302 also keeps identical inactivity timer and knows that UE 301 is released to idle or inactive mode (step 322)。

Fig. 4 describe the RRC connection discharged automatically according to the support UE of novel aspect establish and the message flow of release the Two embodiments.Fig. 4 is similar with Fig. 3.However, in the first embodiment of Fig. 3, it is implicitly assumed that transmitting uplink data occurs in UE It receives RRC connection to establish after message, that is, in MSG5.In order to further decrease the signaling overheads of the UE with low volume data, Upstream data may be attached in RRC connection request message (MSG3).In the second embodiment of Fig. 4, in step 413, UE 401 send subsidiary upstream data and automatic release request with DPR in MSG3.In step 414, BS 402 and carry not Active time and RRC for UE other necessary informations discharged automatically establish message and are responded.RRC connection foundation disappears Breath can be considered as the network response to discharging automatically, and UE 401 and BS 402 correspondingly execute inactivity timer operation. When inactivity timer time-out, UE 401 can be automatically discharged into idle or inactive mode (step 421), without from BS 402 Receive RRC Connection Release.BS 402 also keeps identical inactivity timer and knows that UE 401 is released to the free time or non- Active mode (step 422).

Fig. 5 is described to be implemented according to the inactivity timer and UE discharges automatically first in the DRX of novel aspect operation Example.Before time tl, UE is in RRC idle state.From the t1 moment to the t2 moment, UE is released automatically by sending to have to network The RRC connection request starting connection for putting request is established, and in response, is received with automatic including inactivity timer value The RRC for discharging information is established.From the t2 moment to the t3 moment, UE enters RRC connection mode.UE sends upstream data or receives downlink Data.UE starts inactivity timer after upper primary data transmission, and by the network configuration timer value.It is specific next Say, the starting point of inactivity timer is as follows: 1) requested data volume is completed in the uplink responded for not expecting network Transmission when；2) for the uplink of expectation network response, when completing the reception of corresponding network response；And 3) work as transmission When release auxiliary instruction (Release Assistance Indication, RAI) (Buffer Status Report (BSR)=0).UE RAI can be sent to be used to send therefore can discharge UE without more data with informing network UE.RAI is embodied as buffer state report Accuse BSR=0.Last data transmission is indicated from UE to network, for example, UE is successfully transmitted specified rate according to the request of DPR or BSR Data or UE send BSR=0 indicate its in the near future without more data send.At the t3 moment, when inactive fixed When device time-out when, UE automatically enters that RRC is idle or inactive mode.Network keeps identical timer and knows that UE enters RRC free time or inactive mode.In one embodiment, according to whether indicating RAI (BSR=0) to network, inactivity timer There are two types of spare initial values for value.In the case where indicating RAI, shorter timer value is selected (to notice that shorter value can be for Zero), and in the case where not indicating RAI, UE selects longer timer value.

In the prior art, there are timers triggers to be discharged into a possibility that RRC is idle.For abnormal conditions, open always Dynamic NAS signaling process is to restore connection in timer expiry.However, NAS letter will not be triggered for automatic RRC Connection Release It enables connection restore, and the behavior is configured by new information element.It, can be with since this is the normal behaviour discharged automatically for UE For the beneficial conversion to the inactive mode of RRC and/or RRC light weight connection mode.

Fig. 6 describes the according to the inactivity timer with the automatic release function of UE in the DRX of novel aspect operation Two embodiments.Fig. 6 is similar with Fig. 5.However, in the embodiment in fig 6, since data reach (for example, network response), first is not Active time stops.If any downlink or uplink transmission occurs during inactivity timer operation, the side UE is inactive fixed When device value be reset and stop.Then, UE sends RAI and is again started up automatic release, or discharges dependent on network.In Fig. 6 Example in, UE executes automatic release after the second inactivity timer time-out.

Network side can also remain inactive for timer value for each UE, to maintain the knowledge of UE state.Network side is not Active time operation is not the following steps are included: 1) network startup is lived for what UE discharged automatically after upper primary data transmission Dynamic timer；2) when inactivity timer time-out, network assumes that UE is in idle/inactive mode；If 3) inactive Any downlink or uplink transmission occurs during running for timer, and the side the UE inactivity timer for discharging automatically is reset and stops Only；If 4) receive RAI, the inactivity timer discharged automatically for UE is restarted.The starting point of inactivity timer can by with Lower aspect determines: 1) for not expecting that the uplink (uplink, UL) of network response is transmitted, when being successfully received the number requested by UE When according to amount；2) UL of expectation network response is transmitted, when completing the reception of corresponding network response；And 3) as reception RAI (BSR=0) when.

In one embodiment, network still can be when each data be transmitted using conventional inactivity timer.It is conventional The value of inactivity timer and automatic release inactivity timer can be respectively configured.Furthermore, it is possible to be directed to propagation delay and adjust Whole network side inactivity timer.If starting timer since downlink transfer is completed, subtracted by propagation delay inactive Timer makes cut off and UE side superimposed.If starting timer since uplink is completed, not by propagation delay extension Active time makes cut off and UE side superimposed.

Fig. 7 is the process for the method that the UE based on the visual angle UE in the cordless communication network according to novel aspect discharges automatically Figure.In step 701, UE sends wireless heterogeneous networks (radio resource control, RRC) connection request to base station and disappears Breath to establish RRC connection within a wireless communication network.In a step 702, UE receives RRC connection from base station and establishes message, wherein It includes that UE discharges information automatically that the RRC, which establishes message,.In step 703, UE sends RRC connection setup complete message simultaneously to base station Subsidiary upstream data.When data send/finish receiving, UE starts inactivity timer.In step 704, when being kept by UE When inactivity timer time-out, UE is based on RRC release information and automatically discharges RRC connection.

Fig. 8 is the process for the method that the UE in the cordless communication network according to novel aspect based on network perspective discharges automatically Figure.In step 801, base station receives wireless heterogeneous networks (radio resource control, RRC) connection request from UE and disappears Breath to establish RRC connection within a wireless communication network.In step 802, BS sends RRC connection and establishes message, and is obtaining When UE discharges request automatically, it includes that UE discharges information automatically which, which establishes message,.In step 803, BS receives incidentally upper line number According to RRC connection setup complete message.When UE data send/finish receiving, BS starting discharges inactive automatically for UE Timer.Finally, in step 804, when inactivity timer time-out, BS determines whether UE is in based on RRC release information RRC idle state.
