Background technology

After entering 21st century, number of mobile users has surpassed the number of users of landline telephone at leisure, and wireless data service has also occupied the share above 70% in whole mobile communication business.The 3-G (Generation Three mobile communication system) (3G) that produces in order to satisfy increasing wireless data service demand data is understood by global mobile subscriber gradually and is accepted.3G exists three kinds of wireless transmission standards: WCDMA, CDMA2000 and TD-SCDMA.In three kinds of standards, WCDMA is that performance is best, that popularize the most a kind of in three kinds of standards.

User oriented equipment is called as UE in the WCDMA system.WCDMA UE and network UTRAN wave point are made up of layer one, layer two and layer three, are called physical layer, media access control layer (MAC), radio resource control layer (RRC) respectively.From the angle of protocol hierarchy, there are three kinds of channels on the WCDMA wave point: physical channel, transmission channel and logic channel.

Physical layer provides high-rise required data transmission service, is by using the transmission channel via media access control sublayer to carry out to these professional accesses.Physical layer provides professional by transmission channel to the MAC layer, and the attribute of transmission data itself has determined the transmission channel of what kind and how to have transmitted.

The MAC layer provides professional by logic channel to rrc layer, and the attribute of transmission data itself has determined the kind of logic channel.In the media access control MAC layer, logic channel is mapped as transmission channel.The MAC layer is responsible for the moment source speed according to logic channel, and the transport format combination set (by admitting the control definition) of selecting the selection of suitable transformat (TF) transformat to be connected with each for each transmission channel is closely related.

Rrc layer provides professional by Service Access point (SAP) to high-rise Non-Access Stratum.Rrc layer disposes the protocol entity of low layer by the control interface between itself and lower layer protocol, comprises parameters such as physical channel, transmission channel and logic channel.Rrc layer also will use control interface to carry out real-time command control.

Logic channel---directly carry customer service, according to carrying is that control plane business or user-plane traffic are divided into two big classes: i.e. control channel and Traffic Channel.

The interface of transmission channel---radio interface layer two and physical layer is the service that physical layer provides the MAC layer.According to transmission is to be divided into dedicated channel and common signal channel two big classes at a user's specific information or at all users' public information.

The final avatar of physical channel---various information when wave point transmits, each uses the channel of particular carrier wave frequency, sign indicating number (spreading code and scrambler) and carrier wave relative phase (I or Q) can be interpreted as the channel that a class is specific.

Physical channel is divided into public physic channel and proprietary physical channel two big classes, is divided into following two kinds according to their functional hierarchy:

A kind ofly be and physical channel that the upper strata is irrelevant, these channels only are used for specific physical layer procedure, they are only meaningful for physical layer, for the upper strata is sightless, and these physical channels comprise: primary synchronization channel P-SCH, secondary synchronization channel S-SCH, primary pilot channel P-CPICH, teach frequently channel S-CPICH, Acquisition Indicator Channel AICH, Page Indication Channel PICH and proprietary control physical channel DPCCH at random.

Another physical channel then is the transfer of data that is used for realizing upper layer channel between UE and NodeB, comprising: Physical Random Access Channel PRACH, Primary Common Control Physical Channel P-CCPCH, inferior Common Control Physical Channel S-CCPCH and proprietary data transmitting physical channel DPDCH.

Because when the Session Resources of mobile device comes into force, send the every frame of control module and all need to upgrade the rate-matched of hardware, interweave and coding parameter, receiving the every frame of control module also all needs to upgrade rate-matched, deinterleaving and the decoding parametric of hardware, if all need to calculate new configuration parameter at every turn, time-delay is a more serious problem for the exigent UE of real-time.

Only be noted that RRC can issue the order that physical channel is reshuffled to physical layer in the activating set updating process, when the B process also has with direct-cut operation frequently synchronously.For the alien frequencies direct-cut operation, mobile device need switch to receiver the target frequency and finish system-frame skew (SFO) and obtain with the reception of system message and could dispose the proprietary physical channel of Target cell again.On the stricti jurise, it does not belong to the process that a physical channel is reshuffled.

In physical layer, the layoutprocedure more complicated of dedicated channel, the configuration of common channel process is lacked than the dedicated channel layoutprocedure

The configuration of some dedicated channels.Here with the layoutprocedure that example illustrates physical channel that is configured to of proprietary physical channel.

The foundation of proprietary physical channel comprises following steps:

(1) CHAN receives the physical channel foundation request of RRC;

(2) CHAN checks that physical layer has and has not started a physical channel layoutprocedure, if the channel configuration process has been arranged to be carried out, turn to step (3), request results is not for allowing configuration this time, if not having the channel configuration process carries out, turn to step (3), request results is for allowing configuration this time;

(3) CHAN replys channel configuration affirmation result to RRC, if carry out configuration for allowing, turns to step (4), begins the physical channel configuration;

(4) CHAN if there has been the legal SFO of Target cell, turns to step (7) from the SFO of MEAS request target sub-district; Otherwise, turn to step (5);

(5) the new SFO of MEAS configuration obtains task, if SFO obtains success, MEAS returns the SFO of Target cell to CHAN, and the Target cell dedicated channel is finished synchronously, turns to step (7); Otherwise tell CHAN to obtain the SFO failure, turn to step (6);

(6) CHAN notice RRC obtains the SFO failure, stops the physical channel configuration, turns to step (11);

(7) CHAN calculates the connection vertical shift and the new channel activationary time of Target cell;

(8) CHAN starts the state machine of setting up physical channel, and after activationary time arrived, CHAN sent physical channel to RRC and sets up indication;

(9) the TX/RX module starts synchronous A process and carries out the synchronous of dedicated channel, if RRC is successful synchronously for dedicated channel according to the synchronous indication judgement that RX reports, turns to step (10); Otherwise, turn to step (11);

(10) the physical channel configuration is finished;

(11) physical channel configuration failure.

The release of proprietary physical channel comprises following steps:

(1) CHAN receives the physical channel release request of RRC;

(3) CHAN replys channel configuration affirmation result to RRC, if for allowing to carry out configuration, RRC can finish message to the configuration of network transmitting channel, turns to step (4);

(4) CHAN calculates the UE release time at Target cell;

(5) CHAN starts the state machine of release physical channels, and after activationary time arrived, CHAN sent physical channel to RRC and discharges indication.

The reprovision of proprietary physical channel comprises following steps:

(1) CHAN receives the physical channel reprovision request of RRC;

(5) the new SFO of MEAS configuration obtains task, if SFO obtains success, MEAS returns the SFO of Target cell to CHAN, and the Target cell dedicated channel is finished synchronously, turns to step (7); Otherwise reply CHAN and obtain the SFO failure, turn to step (6);

(6) CHAN notice RRC obtains the SFO failure, stops the physical channel configuration, turns to step (10);

(7) CHAN calculates the CFO of Target cell, and utilizes the CFO of former sub-district to calculate new channel activationary time;

(8) state machine of CHAN startup reprovision physical channel, after activationary time arrived, CHAN sent the indication of physical channel reprovision to RRC, if with frequency direct-cut operation A process, turn to step (9), otherwise turn to step (10);

(10) the physical channel reprovision is finished;

(11) physical channel reprovision failure.

After physical layer CHAN module was received the channel configuration order of layer three RRC module, the different channel configuration state machine of type startup according to order whenever executed a step, enters next state.After channel configuration is finished, the state machine that CHAN can reset and start.Under the situation that any one state machine has started, CHAN can refuse the new channel configuration order of RRC, finishes until this configuration.See also shown in Figure 2ly again, wherein described physical layer and carried out that physical channel discharges, the process of foundation/reprovision.

CHAN is after starting physical channel foundation or reprovision state machine, all can be after giving foundation of TX and RX transmitting channel or reconfiguration request, new session is set up in requirement, and the start-up time of preserving new Radio Resource and calculating good rate-matched, hardware configuration parameter and new session in advance.When arriving, new channel activationary time enables new Session Resources.CHAN is starting physical channel release or reprovision state machine, discharge or reconfiguration request then can for TX and RX transmitting channel, " release mark " of old Session Resources can be changed to TRUE, and the time that will discharge on the mark, after this every frame inspection once, if reached the time of release, then discharge the current sessions resource.See also Fig. 3 and shown in Figure 4, wherein apportion with sequential schematic diagram and flow chart description the situation of six kinds of new and old session updates:

(1) physical layer is received up/down physical channel configuring request of RRC, and TX/RX correspondingly obtains channel parameter from request, set up new Session Resources, is used for control hardware, DSP and safeguards that corresponding Uplink/Downlink connects;

(2) physical layer receives that up/down physical channel of RRC discharges request, TX/RX activationary time in discharge corresponding old Session Resources;

(3) in the activating set updating process, same transmission parameter and code word are adopted in new and old sub-district, and TX/RX does not need to delete old Session Resources, does not need to set up new Session Resources yet;

(4) synchronous B process, Target cell and current service cell are same sub-district, and CFN keeps continuously, and the TX/RX module all needs to distribute new Session Resources space, when activationary time CFNn arrives, discharges old Session Resources, enables new Session Resources;

(5) with the frequency direct-cut operation, the SFO of Target cell and current service cell is different, saltus step can take place in CFN, the TX/RX module is except distributing new Session Resources space, when activationary time arrives, discharge old Session Resources, enable new Session Resources, Connection Frame Number becomes CFNm by the CFNn saltus step;

(6) in the alien frequencies direct-cut operation, UE needs to discharge earlier old proprietary physical channel, finish common signal channel synchronously and the holonomic system message of receiving target sub-district with Target cell, rebulid the proprietary physical channel of communicating by letter again, thereby the new and old session updates of TX/RX module is a discontinuous process with Target cell.

When Session Resources comes into force, the every frame of TX need upgrade hardware rate-matched, interweave and coding parameter, the every frame of RX need upgrade rate-matched, deinterleaving and the decoding parametric of hardware.If all need to calculate new configuration parameter at every turn, time-delay is a more serious problem for the exigent UE of real-time.When new channel activationary time does not arrive, can spend the long time to prepare possible parameter, be saved as several big forms, in every frame configure hardware, indicate according to transmission channel number, frame number and transformat and to select relevant parameters, can reduce the calculating pressure of processor greatly, effectively reduce time delay.

Except can asking physical layer, RRC carries out the foundation of physical channel, physical layer also can irregularly dispose PCCPCH channel (Internal PCCPCH) and obtain a co-frequency neighbor cell SFO, thereby can have the situation of PCCPCH and other common signal channels or dedicated channel coexistence.When hardware is supported multiple down physical channel and a plurality of dedicated channel link simultaneously, physical layer is necessary to prepare a resource management database, so that effectively manage these channel resources, can alleviate the link maintenance burden of RRC like this, and the resource that disposes among the channel link resource of physical layer storage and hardware, the XDSP well can be mapped.Physical layer link conservation of resources principle sees also shown in Figure 5.

Further specify the Radio Resource maintaining method of UE physical layer in the communication system of the present invention below in conjunction with a concrete example.

Two NodeB are arranged near the residing zone of current UE, and two NodeB all adopt omnidirectional antenna, and the sub-district of configuration is respectively PSC 100 and PSC 200 on the NodeB 1,2.NodeB 1 is by RNC 1 control, and NodeB 2 is controlled by RNC 2, but does not have the Iur interface between RNC 1 and the RNC 2.UE quarters on the sub-district 1 (10700,100), and at T0 constantly, UE initiates to insert at random, and network has distributed the dedicated channel resource to UE on sub-district 1.The trigger condition that the quality of sub-district 3 reaches incident eld in T1 sub-district discovery constantly Active Set is just to network eld measurement report, because RNC 2 does not have the Iur interface with RNC1, RNC1 can ask to initiate with the frequency switching, and the UE successful switch is to sub-district 2.Because the data interaction between UE and the network is very few,, has carried out cell selecting behind the UE release link and entered the Idle state at T2 network requests release constantly link.Concrete idle message flow process as shown in Figure 6.

The different sub-district RSCP quality tables constantly of table 1

	T0	T1	T2
				Cell?1：10700，100	-60	-80	-90
Cell?2：10700，200	-95	-70	-65

At T0 constantly, RRC successively asks physical layer to carry out the configuration of PRACH and SCCPCH channel.After interim Random Access Channel configuration is finished, UE just can initiate to insert at random on sub-district 1, just can send RRC Connection Setup message to UE if network is received RRC Connection Request message and allow UE to insert, and the resource of in message, having carried dedicated channel.

After RRC finishes integrity checking and successfully resolves whole message RRC Connection Setup message, ask physical layer to discharge SCCPCH channel and PRACH channel successively after.After two common signal channels had discharged, the proprietary physical channel that RRC can ask physical layer to be based upon on the sub-district 1 connected.The step that proprietary physical channel is set up is as follows:

(6) CHAN request TX/RX sets up new Session Resources, and TX begins to calculate the upstream rate match parameter, interweaves and the coded command parameter, is saved in the new session data structure of TX; RX calculates downstream rate match parameter, deinterleaving and decoding command parameter, is saved in the RX new session data structure;

(7) in the activationary time former frame, CHAN request MEAS upgrades Active Set information, have only sub-district 1 in the Active Set this moment, after new physical channel is set up, MEAS whenever finishes an Active Set Cell searching result is reported to FNG, and FNG carries out the distribution (Assign) of multipath (Finger) and heavily distributes (Re-Aassign) with Search Results;

(8) in the activationary time former frame, CHAN request SRCH carries out channel and sets up search, Search Results is reported to FNG be first Finger assign;

(9) in the activationary time former frame, CHAN disposes new channel parameter for hardware/DSP, and hardware and DSP can formally work on new physical channel at activationary time place frame frame head constantly;

(9) at activationary time place frame, the resource of all physical layer block is upgraded, current descending proprietary physical channel that has sub-district 1, and the resource that only needs in the down link data storehouse to add interpolation sub-district 1, link 0 position gets final product;

(10) at activationary time place frame, the new session resource of TX/RX module comes into effect, and RX can begin to carry out the synchronous of descending dedicated channel; TX begins to layer two transmit frame interrupt message;

(11) at activationary time place frame, CHAN sends physical channel to RRC and sets up indication, and the CHAN channel that resets is set up state machine;

(12) the RX module starts synchronous A process and carries out the synchronous of dedicated channel, reports synchronous indication to RRC, if the RRC judgement is dedicated channel success synchronously, sends to physical layer and finishes indication synchronously;

(13) TX begins to do the open loop power control on the DPCCH channel;

(14) proprietary physical channel is set up and is finished.

At T1 constantly, UE RRC receive require reprovision to the sub-district 2 physical channel reallocation message, checked the integrity protection of message and completely resolved whole message, find that the frequency of sub-district 2 is consistent with the frequency of current service cell, start with the frequency direct-cut operation.The process that physical channel is reshuffled may further comprise the steps:

(1) CHAN receives the physical channel reprovision request of RRC from message queue;

(3) CHAN replys channel configuration to RRC and confirms the result---allow to carry out the operation of physical channel reprovision, start physical channel foundations/reprovision state machine, below state of every execution one step replacing;

(4) CHAN is from the SFO of MEAS request target sub-district, and MEAS obtains sub-district 2 from monitoring collection database SFO returns to CHAN;

(5) CHAN utilizes the CFO of SFO and DOFF calculation of parameter Target cell, and utilizes the CFO of sub-district 1 to calculate the new physics channel activationary time of communicating by letter with sub-district 2;
