CELL-FACH) Status, Cell Paging Channel (CELL-PCH) Status, UMTS Terrestrial Radio Access Network (UTRAN) Registration Area-Paging Channel; URA PCH) Status, IDLE (idle) status and other five states. The radio network controller (RNC) indicates that the UE moves to a certain state through a Radio Resource Control (RRC) message, and the power consumption performance of the UE in different states is different, and the power is saved in the above five states. The performance relationship is as follows: IDLE state>1!^_?01 £1^_?< 11> £1^—FACH>CELL—DCH; that is, the most power-saving in the IDLE state, and the most power-consuming in the CELL-DCH.

In order to save UE energy consumption, when there is no service in the UE-segment period, the RNC will instruct the UE to move from the CELL FACH to the CELL-PCH state. At least two signalings are required for the UE to move from the CELL_F ACH state to the CELL PCH state. For example, the RNC may send the radio bearer reconfiguration to the UE. A message (Radio bearer reconfiguration) to inform the UE that reconfiguration can be performed to the CELL_PCH state, and the UE replies to a radio bearer reconfiguration Complete message.

 FIG. 1 is a flowchart of a state transition method according to an embodiment of the present invention. As shown in FIG. 1, the execution body of the state transition method of this embodiment is a base station. The state transition method of this embodiment can be specifically described as follows.

 100. The UE supporting the seamless state transition is in the CELL_FACH state. If the first timer is started or restarted, the base station starts or restarts the first timer.

 101. When the first timer starts or restarts and runs to the first preset time length, the base station determines that the first timer is turned off.

 102. The base station determines, according to the expiration time of the first timer, the inbound time of the UE moving into the CELL-PCH state, and determines that the UE moves into the CELL-PCH state during the migration time.

 The state transition method of the embodiment can implement the seamless state transition of the UE from the CELL-FACH state to the CELL_PCH state by adopting the foregoing technical solution, and no signaling participation during the state transition process, thereby effectively saving the network. Signaling load, saving network resources.

 Optionally, on the basis of the foregoing embodiment shown in FIG. 1 , the base station starts or restarts the first timer when the first timer is started or restarted, and may specifically include the following situations.

In the first case, when the UE does not support the common enhanced-dedicated channel (common E-DCH), the base station transmits the high-speed downlink sharing of the UE in the High Speed-Shared Control Channel (HS-SCCH). When the downlink data is sent to the UE, the High Speed Downlink Shared Channel-Radio Network Transaction Identifier (H-RNTI) is activated or Restarting the first timer; that is, when the base station sends downlink data to the UE, the base station starts or restarts the first timer.

 In the second case, when the UE supports the common E-DCH, the base station determines that the UE releases the common E-DCH resource, and the base station starts or restarts the first timer. The method for the base station to determine that the user equipment releases the common E-DCH resource may be as follows: The base station determines that there is no UE data in the buffer for a period of time, and then sends an AG=Inactivity message on the Absolute Grant Channel (AGCH) of the E-DCH, and then releases the common E-DCH after receiving the UE. . For example, if the UE detects that there is no data transmission in the buffer for a period of time, the scheduling information (Schedule Information, SI) =0, and after receiving the base station, the UE considers that the UE releases the common E-DCH resource. When the base station determines the manner in which the UE allocates the common E-DCH resource, it feeds back an ACK on an Acquisition Indicator Channel (AICH). For details, refer to related prior art, and details are not described herein again. When the base station allocates the common E-DCH resource to the UE, the base station stops the first timer.

 In the third case, when the UE supports the common E-DCH, but the base station does not allocate the common E-DCH resource to the UE, when the base station sends the H-RNTI of the UE in the HS-SCCH, that is, when the base station sends the downlink data to the UE, the base station starts. Or restarting the first timer; or when the UE supports the common E-DCH, but the base station does not allocate the common E-DCH for the UE, and the "Interruption by HS-DSCH data" is TRUE, the base station is When the HS-SCCH transmits the H-RNTI of the UE, the base station starts or restarts the first timer, where "Interruption by HS-DSCH data" is configurable and can be set to TRUE or FALSE, and TRUE indicates that the downlink data can be interrupted. A timer, FALSE indicates that the downlink data cannot be intended for the first timer. Similarly, when the base station allocates a common E-DCH resource to the UE, the base station stops the first timer.

 In the fourth case, when the base station determines that the UE moves into the Discontinuous Reception (DRX) state, the base station starts or starts the first timer. When the UE enters the continuous receiving state, the base station stops the first timer.

Further optionally, when the UE does not support the common E-DCH, the fourth situation is The state transition method may further include the following steps before the UE starts or restarts the first timer when the UE moves into the DRX state.

 (1) When the UE does not support the common E-DCH, when the base station transmits the H-RNTI of the UE in the HS-SCCH, that is, when the base station sends the downlink data to the UE, the base station starts or restarts the second timer.

 (2) In the process that the second timer starts counting until the second timer counts to reach the second preset time length, the base station detects whether to send downlink data to the UE again (that is, whether the H-RNTI of the UE is sent in the HS-SCCH) When the second timer counts up to the second preset time length, the base station detects that the base station sends the downlink data to the UE again, and performs (3); otherwise, the second timer starts counting until the second timer counts to the second. During the preset time length, when the base station detects that the base station does not send downlink data to the UE again, the base station performs (4).

 In this embodiment, the second preset time length is less than the first preset time length.

 (3) the base station restarts the second timer;

 Equivalent to returning to the above step (1).

 (4) The base station determines that the UE moves into the DRX state.

 Before the base station starts or restarts the first timer or at the same time, specifically, the first timer and the second timer are started simultaneously; or the second timer is turned off (that is, when the second timer runs to the second preset time length) The first timer is started; or after the second timer is cut off, the first timer is started when the UE enters DRX on. Further, when the first timing and the second timer are simultaneously started, the second timer preset length is required to be smaller than the first timer preset length.

 Further, optionally, when the UE supports the common E-DCH, in the foregoing fourth case, when the UE moves into the DRX state, before the base station starts or restarts the first timer, the state transition method may further include the following steps. .

 (a) When the UE supports the common E-DCH, the base station determines that the UE releases the common E-DCH resource, the base station starts or restarts the second timer.

(b) When the UE supports the common E-DCH, and the base station does not allocate the common E-DCH resource to the UE, the base station sends the H-RNTI of the UE when the HS-SCCH transmits the UE, that is, the base station sends the UE the H-RNTI. When the downlink data is sent, the base station starts or restarts the second timer; or when the UE supports the common E-DCH, the base station does not allocate the common E-DCH resource for the UE, and "the downlink data interrupts the DRX indication (DRX Interruption by HS-DSCH) Data) " is TRUE, when the base station transmits the H-RNTI of the UE in the HS-SCCH, the base station starts or restarts the second timer, where "DRX Interruption by HS-DSCH data" is configurable and can be TRUE or FALSE, TRUE indicates that the downlink data can interrupt DRX, that is, the downlink data can restart or start the second timer; FALSE indicates that the downlink data cannot interrupt DRX, that is, the downlink data cannot interrupt the second timer.

 (c) when the base station allocates the common E-DCH resource to the UE, the base station stops the second timer; otherwise, when the second timer runs to the second preset time length, the second timer is cut off, and the base station determines that the UE moves in. DRX status.

 The second timer in the foregoing embodiment may be a T321 timer, or another timer.

 Before the base station starts or restarts the first timer or at the same time, specifically, the first timer and the second timer are started at the same time, or when the second timer is turned off, the first timer is started, or after the second timer is turned off, The first timer is started when the UE enters DRX on.

 Optionally, on the basis of the foregoing embodiment shown in FIG. 1 , the state transition method further includes: determining, when the first timer is started or restarted, running the first preset time length, determining the first timer Whether the restart condition of the above four conditions is met, and when the first timer meets the restart condition, the first timer is restarted. Otherwise, the first timer is run to the first preset time length, and the first timer is determined to be off, that is, 101 above.

 Optionally, on the basis of the foregoing embodiment shown in FIG. 1 , when the base station detects that the base station sends the downlink data to the UE before the first timer is synchronized to the first preset time length, the base station may further include: The timer, in the corresponding 100, "starts or restarts the first timer when the first timer is started or restarted", and may specifically include the following.

When the predefined observation time point is reached, the base station starts the first timer; for example, the predefined observation time point is the time point of the system frame number (SFN) for N to be equal to M, N and M are both 0 or a positive integer, N is greater than the value of the first preset time length. Optionally, on the basis of the foregoing embodiment shown in FIG. 1 , before 100, the method further includes: when the UE supporting seamless state transition is in a CELL-FACH state, the base station receives a frame protocol (Frame Protocol; FP) sent by the RNC. a frame, the FP frame carrying a paging opportunity parameter for transmitting Paging Indicator (PI) information.

 Correspondingly, after the "determining that the UE moves into the CELL_PCH state after the migration time" in the foregoing 102, the state transition method may further include: the base station sending the PI information to the UE according to the paging occasion indicated by the paging opportunity parameter, It is used by the UE to monitor PI information at the paging occasion.

 Further, optionally, the paging opportunity parameter in the foregoing embodiment may be a cell SFN or a connection frame number (CFN) determined by the RNC to indicate that the PI information is sent on the paging channel, and the FP is The frame further includes a paging indication, where the paging indicator is used to indicate that the PI in the corresponding location is 1 or 0; or the paging occasion parameter may also be an IMSI, or the paging timing parameter may also be an IMSI and a discontinuous reception period. Length (DRX Cycle Length). Or the paging opportunity parameter is the H-RNTI of the UE; or the paging occasion parameter may also be the H-RNTI and the DRX Cycle Length of the UE. When the DRX Circle Length is not included in the paging opportunity parameter, the RNC configures the DRX Cycle Length to the NodeB through common signaling to reduce the content in the FP frame.

 Further optionally, when the paging opportunity parameter is IMSI, or the paging opportunity parameter is IMSI and DRX cycle length (Circle Length); the state transition before sending the PI information to the UE according to the paging occasion indicated by the paging opportunity parameter The method may further comprise: determining a paging occasion based on the IMSI and the DRX cycle length, the paging occasion being a cell SFN or a CFN.

 For example, the paging occasion is determined according to the length of the IMSI and the DRX cycle, and the following may be adopted.

Paging Timing = ( IMSI div K ) mod ( DRX Period Length) + n * DRX Period Length, where div indicates division, and K indicates the sub-common control physical channel carrying the paging channel (Paging Channel; PCH) ( Secondary Common Control Physical Channel; S-CCPCH) Number or High Speed Downlink Packet Access (HSDPA) The number of corresponding Paging Indicator Channels (PICHs), K is a positive integer greater than 0, mod represents a remainder, and n is a positive integer equal to 0 or less than the maximum value of SFN or CFN.

 When the paging opportunity parameter is the UE's H-RNTT, or the paging opportunity parameter is the UE's H-RNTI and DRX Cycle Length. Correspondingly, before the sending of the PI information to the UE according to the paging occasion indicated by the paging opportunity parameter, the state transition method further includes: determining a paging occasion according to the H-RNTI and the DRX Circle Length of the UE; SFN or CFN.

 Optionally, on the basis of the foregoing embodiment shown in FIG. 1 , before the “base station starts or restarts the first timer” in 100, the state transition method may further include: receiving, by the base station, a first timer that is sent by the RNC. The first preset time length.

 Optionally, on the basis of the foregoing embodiment shown in FIG. 1 , after determining, in 102, that the UE moves to the CELL_PCH state after the migration time, the RNC may further include: when the UE has uplink data, the RNC receives the UE. Uplink data sent directly by the base station. At this time, compared with the prior art, the UE does not need to send the measurement control message to the base station first, but can directly send the uplink data. Compared with the prior art, signaling can be effectively reduced and network resources can be saved.

 Optionally, on the basis of the foregoing embodiment shown in FIG. 1, where the base station determines, according to the cutoff time of the first timer, the UE moves into the CELL-PCH state, and determines that the UE moves during the migration time. In the CELL_PCH state, the method may include: determining, by the base station, that the deadline of the first timer is the inbound time, and determining that the UE moves into the CELL-PCH state during the migration time; or determining, by the base station, the deadline of the first timer The three preset time lengths are the migration time, and it is determined that the UE moves into the CELL PCH state during the migration time.

 Correspondingly, after the base station determines that the UE moves to the CELL_PCH state after the migration time, the base station may further include: the base station sends an indication message to the RNC to notify the RNC UE to move into the CELL_PCH state.

Optionally, the determining, by the eNB, the expiration time of the first timer and the third preset time length are the migrating time, and determining that the UE moves into the CELL-PCH state during the migrating time. Corresponding The base station sends a timeout period in which the first timer can be carried in the indication message to the RNC, and the time of the third preset time length is sent to notify the RNC that the UE moves into the CELL when the first timer expires for the third preset time length. PCH status. Or optionally, the RNC receives the MIKE-PCH status indication sent by the NodeB, and then sends the data to the base station after the predefined observation time point to the current time period, and needs to reconstruct the FP frame, that is, construct the HS. -DSCH DATA FRAME TYPE3 or notification, such as Radio Link Control (RLC) or Radio Resource Control (RRC).

 For example, FIG. 2 is an embodiment of a predefined observation time point provided by an implementation of the present invention. As shown in Fig. 2, the above SFN mode N=0 is taken as an example for description. In Fig. 2, 0, 1, 2, ... represent SFN. In this embodiment, taking N as an example, the predefined observation time point is a point where SFN mode 7 is equal to 0, and the first preset time length of the first timer is 2. Assume that when the SFN=16, the first timer is cut off, the base station informs the RNC to move into the CELL_PCH state (that is, the RNC maintains the state of the UE as the CELL_PCH state), and the RNC receives the moved CELL PCH status sent by the base station when the SFN=17. If the RNC sends data to the base station during the period from SFN=14 to SFN=17, the RNC will re-transmit the FP frame for re-establishing the data, that is, construct HS-DSCH DATA TYPE3 retransmission, or notify RLC. Layer or RRC layer retransmission.

 It should be noted that the third preset time length in the foregoing embodiment may be sent by the RNC to the base station, and correspondingly, the method may further include: receiving, by the base station, a third preset time length sent by the RNC. Or the third preset time length may also be preset by the RNC, the base station, and the UE.

 It should be noted that the first timer in the foregoing embodiment may be referred to as an inactivity timer, and the first timer is sent by the RNC to the UE through a dedicated RRC message, such as a radio bearer reconfiguration message. of. Correspondingly, the RNC notifies the base station through dedicated FP frames or signaling. Or the first timer is sent by the RNC to the UE by using a system message, and correspondingly, the RNC notifies the base station by using public signaling or a public FP frame.

The state transition method of the foregoing embodiment, by adopting the foregoing technical solution, can implement seamless state transition between the CELL_FACH state and the CELL_PCH state of the UE, and the state transition In the process, there is no signaling participation, which can effectively save the signaling load of the network and save network resources.

 In the first case, when the UE does not support the common E-DCH, the UE monitors the H-RNTI of the UE in the HS-SCCH, that is, when the UE receives the downlink data sent by the base station, the UE starts or restarts the first timer.

In the second case, when the UE supports the common E-DCH, the UE releases the common E-DCH resource. When the source is up, the UE starts or restarts the first timer; when the UE competes for the common E-DCH resource, the UE stops the first timer.

 In the third case, the UE supports the common E-DCH, but the UE is not allocated to the common E-DCH resource, and the UE detects the H-RNTI of the UE in the HS-SCCH, that is, when the UE receives the downlink data sent by the base station, the UE starts. Or restarting the first timer; or the UE supports the common E-DCH, but the UE is not allocated to the common E-DCH resource, and the "Interruption by HS-DSCH data" is TRUE, the UE monitors the UE in the HS-SCCH. The H-RNTI starts or restarts the first timer, where 'Interruption by HS-DSCH data' is configurable and can be set to TRUE or FALSE. TRUE indicates that the downlink data can interrupt the first timer, FALSE indicates the downlink. The data cannot be intended for the first timer. Similarly, when the UE competes for the common E-DCH resource, the UE stops the first timer.

 In the fourth case, when the UE moves into the DRX state, the UE starts or restarts the first timer. Further, when the UE does not support the common E-DCH, in the fourth case, when the UE moves into the DRX state, before the UE starts or restarts the first timer, the state transition method may further include the following content.

 (1) When the UE does not support the common E-DCH, when the UE listens to its own H-RNTI on the HS-SCCH, that is, when receiving the downlink data sent by the base station, the UE starts or restarts the second timer.

(2) When the UE supports the common E-DCH and the UE does not contend for the common E-DCH resource, the UE starts its own H-RNTI on the HS-SCCH, that is, when the UE receives the downlink data sent by the base station, the UE starts. Or restarting the second timer; or when the UE supports the common E-DCH, the UE does not compete for the common E-DCH resource, and the "DRX Interruption by HS-DSCH data" is TRUE, the UE listens itself to the HS-SCCH. In the H-RNTI, the UE starts or restarts the second timer, where "DRX Interruption by HS-DSCH data" is configurable and can be TRUE or FALSE, TRUE indicates that downlink data can interrupt DRX, that is, downlink data can be made. The second timer is restarted or started; FALSE indicates that the downlink data cannot interrupt DRX, that is, the downlink data cannot interrupt the second timer. (3) When the UE competes for the common E-DCH resource, the UE stops the second timer; otherwise, when the second timer runs to the second preset time length, the second timer expires, and the UE moves into the DRX state. When the first timer and the second timer are simultaneously started, the second preset time length is less than the first preset time length. When the second timer is started first, and the first timer is started after the UE enters the DRX, the second preset time length and the first preset time length have no size limit.

The "DRX Interruption by HS-DSCH data" is configurable and can be TRUE or FALSE. TRUE indicates that downlink data can interrupt DRX, that is, downlink data can restart or start the second timer; FALSE indicates that downlink data cannot be interrupted. DRX, that is, downlink data cannot interrupt the second timer.

 (c) when the UE competes for the common E-DCH resource, the second timer is stopped; otherwise, when the second timer runs to the second preset time length, the second timer is turned off (ie, the second timer is full, That is, the second timer runs to the second preset time length, and the UE moves into the DRX state.

 Optionally, on the basis of the foregoing embodiment shown in FIG. 1, when the UE monitors its own H-RNTI on the HS-SCCH before the first timer reaches the first preset time length, that is, the UE receives The downlink data sent by the base station may further include: when the UE stops the first timer, the "starting or restarting the first timer" in the corresponding 200 may include: when a predefined observation time point is reached, The UE starts or restarts the first timer; the predefined observation time point is a time point at which the SFN is equal to N, and N and M are both 0 or a positive integer, and N is greater than the value of the first preset time length.

 The predefined observation time point is that the UE, the base station, and the RNC are scheduled to be good. For example, the time of SFN mode N=0 can be taken as a predefined observation time point, that is, the first timer is started when the SFN mode N=0 is satisfied. . Where N is fixed or configurable. The first timer and/or N is sent by the RNC to the UE through a dedicated RRC message, such as a radio bearer reconfiguration message. Correspondingly, the RNC notifies the base station of the first timer and/or by using a dedicated FP frame or signaling. N.

 Or the first timer and/or N is sent by the RNC to the UE by using a system message, and correspondingly, the RNC notifies the base station of the first timer and/or N by using common signaling or a common FP frame.

 That is to say, the RNC can calculate the predefined observation time point to tell the base station and the UE, or the RNC will query the base station or the UE to calculate a parameter such as N at a predefined time point, and the RNC, the base station and the UE each calculate a predefined observation according to the calculation.

The time, and before moving to the CELL_PCH state, the method may further include: receiving, by the UE, a third preset time length sent by the RNC.

 It should be noted that the optional technical solution of the subsequent expansion of the embodiment shown in FIG. 3 is the same as the implementation process of the subsequent extended optional technical solution of the embodiment shown in FIG. The description of the optional technical solutions of the subsequent extension of the example will not be repeated here.

The state transition method of the above embodiment can implement the UE by using the above technical solution. The seamless state transition between the CELL_FACH state and the CELL-PCH state, and no state of signalling during the state transition process, can effectively save the signaling load of the network and save network resources.

 FIG. 4 is a signaling diagram of a state transition method according to an embodiment of the present invention. As shown in FIG. 4, the state transition method of this embodiment may specifically include the following content.

 300. The UE reports to the RNC the capability indication that the UE supports seamless (no signaling) state transition.

301. The base station reports to the RNC the capability indication that supports seamless state (no signaling) migration. The capability indication can identify the ability of the base station or cell or local cell to support unsignaled state transitions.

 302. The RNC sends a configuration message carrying a CELL_FACH state to the UE, such as a radio bearer reconfiguration (Poly Bearer Reconfiguration) message, to indicate that the UE moves into a CELL FACH state.

 303. The UE completes the CELL-FACH state configuration according to the radio bearer reconfiguration message, moves to the CELL FACH state, and sends the Radio Bearer Reconfiguration Complete to the RNC.

(Radio bearer reconfiguration complete message), so that the RNC can know that the UE has moved into the CELL-FACH state.

 304. The RNC sends the first preset time length corresponding to the first timer to the base station and the UE, respectively. The case of step 304 corresponds to determining, by the RNC, a first preset time length corresponding to the first timer. And step 304 and the previous step 300-step 303 have no chronological order. The first preset time length in the actual application may also be predefined, and step 304 is not required at this time.

 305. The RNC sends, to the base station, an FP frame carrying a PI and a Connection Frame Number (CFN).

The CFN is used to determine, directly or indirectly, the time at which the PI is sent on the PICH. For example, the CFN may refer to the cell system frame number corresponding to the PI transmitted on the PICH; for example, the CFN is the cell SFN corresponding to the start time of other channel frames (such as S-CCPCH/HS-SCCH/HS-PDSCH). And then determining the PI to be sent on the PICH according to the timing relationship between the PICH and the channel. Time (ie paging time). For example, if the CFN refers to the SFN corresponding to the beginning of the S-CCPCH frame, the paging time is the SFN corresponding to the first 3 slots of the CFN; if the CFN refers to the cell SFN corresponding to the beginning of the HS-SCCH frame, The paging time is the SFN corresponding to the first three slots of the CFN. If the CFN is the cell SFN corresponding to the start of the HS-PDSCH (High Speed Physical Downlink Shared Channel) frame, the paging is performed. The timing is the SFN corresponding to the first 5 slots of the CFN.

 Or, the paging occasion may be determined according to the length of the IMSI and the DRX cycle in the foregoing embodiment, where the corresponding RNC may carry the IMSI in the FP frame sent by the base station, correspondingly by the base station according to the manner of the foregoing embodiment, according to the IMSI and the CELL- The length of the DRX cycle of the PCH determines the paging occasion, and the length of the CELL-PCH DRX period can be carried by the RNC to the NodeB through the FP frame or the common signaling. For details, refer to the description of the foregoing embodiment, and details are not described herein again.

 Alternatively, the base station may calculate a paging occasion according to the H-RNTI and the DRX parameter of the CELL_PCH, for example: (SFN - H-RNTI + 65536) mod DRX cycle length < 1 , that is, the SFN satisfying the inequality is the paging occasion of the UE. . The SFN is the system frame number, the H-RNTI is the temporary identifier of the high-speed downlink shared channel wireless network of the UE, the DRX cycle length is the period length of the DRX, and mod represents the remainder.

 306. The base station and the UE respectively start or restart the first timer.

 For the manner in which the base station and the UE start or restart the first timer in this embodiment, reference may be made to the description of the related embodiments.

 In this embodiment, the base station and the UE start or restart the first timer to be synchronized. For example, in this embodiment, the base station sends the downlink data, and the UE synchronizes when receiving the downlink data sent by the base station. When the UE supports the common E-DCH, the UE releases the common E-DCH resource and the base station determines that the UE releases the common E-DCH resource is also synchronized. Optionally, in this embodiment, the technical solution of the present invention is described by taking only the first timer as an example.

Optionally, in the actual application, before or at the same time, the base station and the UE simultaneously start the second timer, and the startup or restart or stop mode of the second timer may refer to The description of the related embodiments will not be repeated here.

 307. On the base station side, after the first timer is cut off, the base station determines that the UE moves into the CELL_PCH state when the first timer expires.

 Specifically, if the UE does not support the common E-DCH: the base station sends the H-RNTI of the UE on the HS-SCCH, that is, sends the downlink data to the UE, and then starts or restarts the first timer; After the timer runs to the first preset time length, the base station determines that the UE moves into the CELL_PCH state when the first timer expires;

 If the UE supports the common E-DCH: the base station does not allocate the common E-DCH resource to the UE, the base station sends the H-RNTI of the UE on the HS-SCCH, that is, sends the downlink data to the UE, and then starts or restarts the first timer; Or the "Interruption by HS-DSCH data" is TRUE, and the base station does not allocate the common E-DCH resource to the UE, and the base station transmits the downlink data of the UE to the H-RNTI of the UE on the HS-SCCH, and then starts or restarts. The first timer is stopped when the base station allocates the common E-DCH resource to the UE, and the first timer is started or restarted when the base station allocates the common E-DCH resource for the UE; After the first timer runs to the first preset time length, the base station determines that the UE moves into the CELL_PCH state when the first timer expires. When the UE supports the common E-DCH, the base station allocates the common E-DCH resource to the UE, and stops the first timer.

 Specifically, the base station side has the following three options:

Option 1: After the first timer expires, if the base station sends downlink data to the UE, it first determines whether to send the PI according to the paging opportunity parameter CFN or determines the time for sending the PI according to the IMSI and the length of the CELL PCH DRX cycle. Then, at this point in time, the paging message is sent at the PICH, and then the data is transmitted on the re-related HS-SCCH/HS-PDSCH channel. Before the first timer expires, if the base station sends downlink data to the UE, if the UE is in the continuous receiving state, the data is directly transmitted on the HS-SCCH/HS-PDSCH channel; if the UE is in the discontinuous receiving state, the DRX on The time is to send data to the UE on the HS-SCCH/HS-PDSCH channel, where the calculation of DRX on is calculated according to H-NTI, for example (SFN - H-RNTI + 65536) mod DRX cycle length < Rx_burst, that is, the data of the UE is scheduled in the SFN satisfying the inequality. The SFN is the system frame number, the H-RNTI is the high-speed downlink shared channel radio network temporary identifier of the UE, the DRX cycle length is the period length of the DRX, and mod is the remainder; Rx_burst is the length of the DRX on.

 Option 2: After the first timer expires, if the base station sends downlink data to the UE, the base station first calculates the paging occasion according to the IMSI and the CELL_PCH DRX cycle length, such as Paging Occasion = (IMSI) Mod DRX cycle length ) + n * DRX cycle length, then send paging information on the Paging Indicator Channel (PICH) at the paging occasion, and then on the relevant HS-SCCH/HS-PDSCH channel Send data, where DRX cycle length is CELL—PCH DRX length, n is the maximum value of 0, 1, 2 SFN, which is the current system frame number. Before the first timer expires, if the base station sends downlink data to the UE, if the UE is in the continuous receiving state, the data is directly sent to the UE on the HS-SCCH/HS-PDSCH; if the UE is in the discontinuous reception state, First, the time of the DRX on is calculated based on the IMSI and the CELL-FACH DRX parameters. For example, the DRX on start time is (IMSI mod DRX cycle length) + n * DRX cycle length, where the length of the DRX cycle length is CELL-FACH DRX cycle length, then The time period in which the UE is in DRX on is the corresponding SFN/CFN within the DRX-burst length from the DRX on start time; then the data is sent to the UE in the DRX on time period.

Option 3: If the base station has data to be sent to the UE after the first timer expires, first calculate the paging occasion according to the H-RNTI and the CELL_PCH DRX parameters, such as (SFN - H-RNTI + 65536) mod DRX cycle length <1, that is, the SFN that satisfies the inequality first transmits the PI, where the SFN is the system frame number, the H-RNTI is the high-speed downlink shared channel radio network temporary identifier of the UE, the DRX cycle length is the period length of the DRX, and mod represents the remainder. Then, the data is sent on the related HS-SCCH/HS-PDSCH. If the base station has data to send to the UE before the first timer expires, if the UE is in the continuous receiving state, it is on the HS-SCCH/HS-PDSCH. Transmitting data to the UE; if the UE is in a discontinuous reception state, first according to the H-RNTI And the CELL-FACH DRX parameter calculates the timing of DRX on, such as:

 (SFN - H-RNTI + 65536) mod DRX cycle length < Rx burst, that is, the timing at which the SFN satisfying the inequality is DRX on, that is, the UE is in the receiving state; wherein SFN is the system frame number, and H-RNTI is the high-speed downlink of the UE. Shared channel radio network temporary identifier, DRX cycle length is the period length of DRX, mod indicates the remainder; Rx_burst indicates the length of DRX on. The base station then transmits data to the UE at the DRX on timing.

 308. On the UE side, after the first timer is cut off, the UE moves to the CELL_PCH state when the first timer expires.

 Specifically, if the UE does not support the common E-DCH: the UE detects the H-RNTI of the UE on the HS-SCCH, that is, the UE receives the data sent by the base station, starts or restarts the first timer; When the first timer runs to the first preset time length, the UE moves into the CELL_PCH state;

 If the UE supports the common E-DCH: the UE is not allocated the common E-DCH resource, the UE starts or restarts the first timer when the HS-SCCH listens to its own H-RNTI; or the UE is not assigned the common E-DCH The resource, and the ''Interruption by HS-DSCH data' is TRUE, when the UE listens to its own H-RNTI on the HS-SCCH, starts or restarts the first timer; when the UE is allocated to the common E-DCH resource, Stopping the first timer; when the UE releases the common E-DCH resource, the first timer is started or restarted; after the first timer expires, the UE moves into the CELL PCH state. When the UE supports the common E-DCH, the UE competes for the common E-DCH resource, stop the first timer.

The foregoing 307 and 308 are performed synchronously, and the technical solutions of the present invention are described on the base station side and the UE side, respectively. For the start or restart condition of the first timer, refer to the triggering conditions of the first timer start/restart/stop in the foregoing related embodiments, and details are not described herein again. At the same time, the second timer can be started or restarted before or at the same time, or the second timer is started or restarted. For details, refer to the second timer in the related embodiment. The trigger condition is not described here. The alternatives described in step 307 are three alternatives on the base station side, corresponding to the three alternatives on the base station side, respectively corresponding to the following three schemes on the UE side, as follows: Option 1: After the UE moves into the CELL_PCH, the UE determines the paging occasion according to the paging timing parameter IMSI and the CELL-PCH DRX parameter, and listens to the PI at the paging occasion; if the received PI is 1, the UE starts to listen to the relevant HS-SCCH/HS. - PDSCH channel. After the UE moves into the CELL-FACH, if the UE is in the continuous receiving state, it directly receives data on the HS-SCCH/HS-PDSCH channel; if the UE is in the discontinuous receiving state, the DRX on timing is in the HS-SCCH/HS- The data is received on the PDSCH channel, where the calculation of DRX on is calculated according to the H-RNTI and DRX parameters, such as (SFN-H-RNTI + 65536) mod DRX_cycle length < Rx_burst. Option 2: After moving into the CELL-PCH, the UE first calculates the paging occasion according to the IMSI and the CELL-PCH DRX cycle length, such as paging occasion (Paging Occasion) = (IMSI mod DRX cycle length) + n * DRX Cycle length, then listen to the paging indication on the PICH at the paging occasion, and if the paging indication is 1, start to listen to the relevant HS-SCCH/HS-PDSCH channel; wherein the DRX cycle length is CELL-PCH DRX length, n is 0, 1, 2... The maximum value of SFN is the current system frame number. After the UE moves into the CELL-FACH, if the UE is in the continuous receiving state, the data is continuously monitored on the HS-SCCH/HS-PDSCH; if the UE is in the discontinuous receiving state, the DRX is first calculated based on the IMSI and the CELL-FACH DRX parameters. The time of on, for example, the start time of DRX on is SFN/CFN corresponding to the value obtained by (IMSI mod DRX cycle length) + n * DRX cycle length, wherein the DRX cycle length length is CELL-FACH DRX cycle length, then the UE is in DRX on The time period is the corresponding CFN in the DRX-burst length from the start time of the DRX on; then the UE starts to continuously monitor the HS-SCCH/HS-PDSCH channel in the DRX on time period, where n is 0, 1 , 2. The maximum value taken by η ensures that the resulting paging occasion does not exceed the maximum value of SFN or CFN.

Option 3: After moving into CELL_PCH, the UE first calculates the paging occasion according to the H-NTI and CELL PCH DX parameters, such as (SFN - H-RNTI + 65536) mod DRX—cycle length < 1 , that is, the SFN listening PI that satisfies the inequality, if the PI is monitored (that is, the PI read on the PICH channel is 1), and then the data is monitored on the relevant HS-SCCH/HS-PDSCH; After the UE moves into the CELL_FACH, if the UE is in the continuous receiving state, the HS-SCCH/HS-PDSCH is continuously monitored; if the UE is in the discontinuous receiving state, the timing of the DRX on is first calculated according to the H-RNTI and the CELL-FACH DX parameters. , for example:

 (SFN - H- NTI + 65536) mod DRX cycle < Rx - burst, that is, the timing at which the SFN satisfying the inequality is DRX on, that is, the UE is in the receiving state; the UE listens to the HS-SCCH/HS-PDSCH channel at the DRX on timing. The SFN is the system frame number, the H-RNTI is the UE's high-speed downlink shared channel radio network temporary identifier, the DRX_cycle_length is the DRX period length, and mod is the remainder; Rx_burst indicates the length of the DRX on.

 The three options on the UE side correspond to the three alternatives on the base station side. 309. After the UE moves into the CELL_PCH state, when uplink data is sent, the uplink data is directly sent to the base station.

 The state transition method of the embodiment can implement the seamless state transition between the CELL-FACH state and the CELL-PCH state of the UE by using the foregoing technical solution, and the signaling transition is not effective in the state transition process. It saves the signaling load of the network and saves network resources.

 FIG. 5 is a signaling diagram of a state transition method according to another embodiment of the present invention. As shown in FIG. 5, the state transition method of the embodiment may include the following steps: Steps 400-404 are the same as 300-304 in the embodiment shown in FIG. 4, and may refer to the foregoing embodiment of FIG. 4 in detail. Record, no longer repeat here.

 405. The RNC sends an FP frame carrying the PI and the CFN to the base station.

RNC 405 or the base station may transmit the IMSI carried in the FP frame, this time CELL_PCH DRX Cycle length from the RNC through the common signaling, such as physical shared channel reconfiguration process configured to NodeB ₀

Or the RNC may also send the bearer carrying the IMSI and the CELL_PCH DRX to the base station. Cycle FP frame;

 Or, in 405, the RNC may also send the FP frame carrying the H-RNTI to the base station, where the CELL PCH DRX Cycle length is configured by the RNC to the NodeB through common signaling, such as a physical shared channel reconfiguration process.

 Or in 405, the RNC may also send an FP frame carrying the H-RNTI and the CELL_PCH DRX Cycle to the base station;

 406. The base station and the UE respectively start a first timer.

 407. After the first timer is cut off, the base station determines that the UE moves to the CELL_PCH state when the first timer expires.

 Specifically, if the UE does not support the common E-DCH: the base station sends the H-RNTI of the UE on the HS-SCCH, that is, sends the downlink data to the UE, and then starts or restarts the first timer; After a timer runs to the first preset time length, the base station determines that the UE moves into the CELL PCH state when the first timer expires;

 If the UE supports the common E-DCH: the base station does not allocate the common E-DCH resource to the UE, the base station sends the H-RNTI of the UE on the HS-SCCH, that is, sends the downlink data to the UE, and then starts or restarts the first timer; Or the "Interruption by HS-DSCH data" is TRUE, and the base station does not allocate the common E-DCH resource to the UE, and the base station transmits the downlink data of the UE to the H-RNTI of the UE on the HS-SCCH, and then starts or restarts. The first timer is stopped when the base station allocates the common E-DCH resource to the UE, and the first timer is started or restarted when the base station allocates the common E-DCH resource for the UE; After the first timer runs to the first preset time length, the base station determines that the UE moves into the CELL_PCH state when the first timer expires. When the UE supports the common E-DCH, the base station allocates the common E-DCH resource to the UE, and stops the first timer.

And further, after the first timer is cut off, if the base station has three options for transmitting the downlink data to the UE, refer to the description of the detailed implementation manner of the base station side in the 307 in the foregoing embodiment shown in FIG. 4, where No longer. 408. On the UE side, after the first timer is cut off, the UE moves to the CELL PCH state when the first timer expires.

 If the UE supports the common E-DCH: the UE is not allocated the common E-DCH resource, the UE starts or restarts the first timer when the HS-SCCH listens to its own H-RNTI; or the UE is not assigned the common E-DCH The resource, and the ''Interruption by HS-DSCH data' is TRUE, when the UE listens to its own H-RNTI on the HS-SCCH, starts or restarts the first timer; when the UE is allocated to the common E-DCH resource, Stopping the first timer; when the UE releases the common E-DCH resource, the first timer is started or restarted; after the first timer expires, the UE moves into the CELL_PCH state. When the UE supports the common E-DCH, the UE competes for the common E -DCH resource, stop the first timer.

 In the uplink random access procedure, after the UE transmits the preamble preamble, it transmits to the DCCH (Dedicated Control Channel) / DTCH (Dedicated Traffic Channel), at the maximum period for collision resolution phase. If the AG is received before the timeout, the UE stops the first timer, and does not move into the CELL PCH state even if the first timer is full; if the AG is not received before the maximum period for collision resolution phase expires, the first After the timer expires, it moves into the CELL_PCH state. For the CCCH transmission, the maximum E-DCH resource allocation for the CCCH has been reached, and the UE enters the CELL_PCH when the first timer is full, and the first timer is restarted when the UE releases the common E-DCH resource; After the first timer expires, the UE moves into the CELL-PCH state.

Further, when the UE moves into the three options of receiving data after the CELL_PCH, for details, refer to the description of the detailed implementation manner of the UE side in the 308 in the foregoing embodiment shown in FIG. I will not repeat them here. The foregoing 407 and 408 are performed synchronously, and the technical solutions of the present invention are described on the base station side and the UE side, respectively.

After the UE moves into the CELL-PCH, the RNC has the downlink data transmission of the UE, and sends the high-speed downlink shared channel data frame type 3 to the base station (HS-DSCH (High Speed Downlink Shared Channel; HS-DSCH) DATA FRAME TYPE3 When the UE moves into the CELL-FACH, there is downlink data transmission of the UE, and the RNC sends the high-speed downlink shared channel data frame type 2 (HS-DSCH DATA FRAME TYPE2) to the base station.

 510. After receiving the HS-DSCH DATA FRAME TYPE3, the base station first sends the PI in the paging occasion specified in the HS-DSCH DATA FRAME TYPE3, and then sends the data on the relevant HS-SCCH/HS-PDSCH channel; When entering the CELL-FACH, after receiving the HS-DSCH DATA FRAME TYPE2 sent by the RNC, the base station does not need to send the PI and directly transmits data on the HS-SCCH/HS-PDSCH channel.

604. The RNC sends, to the base station and the UE, a first preset time length corresponding to the first timer and a third preset time length. Or optionally, the first preset time length and the third preset time length corresponding to the first timer may be predefined by the RNC, the base station, and the UE, and correspondingly, the first preset time length and the third The preset length of time is configurable.

 605-608 is the same as 305-308 in the embodiment shown in FIG. 4 above. For details, refer to the description of the embodiment shown in FIG. 4, and details are not described herein again.

 When the base station sends the downlink data or the UE receives the downlink data sent by the base station, the UE does not change the inbound time of the UE moving into the CELL_PCH state, and correspondingly, after 607, the following may also include the following 609.

 609. The base station side, after the first timer is cut off, the base station sends an indication message to the RNC to carry the time when the UE moves into the CELL PCH state or the time when the first timer expires, to notify the RNC that the UE moves during the migration time. Enter the CELL PCH status;

 Through the above 609, the RNC can update the state of the UE in the migration time according to the received indication message.

 610. On the UE side, the UE moves to the CELL_PCH state after the first timer expires. After the UE enters the CELL PCH, the UE first listens to the PI and then receives the downlink data at the paging occasion.

 FIG. 8 is a signaling diagram of a state transition method according to still another embodiment of the present invention. As shown in FIG. 8, the state transition method of this embodiment may specifically include the following steps:

 700. The UE reports the capability indication that the UE supports seamless state transition to the RNC.

 701. The RNC sends a configuration message carrying a CELL_F ACH state, such as a Radio Bearer Reconfiguration message, to the UE, to indicate that the UE moves into a CELL FACH state.

 702. The UE completes the CELL-FACH state configuration according to the radio bearer reconfiguration message, moves to the CELL FACH state, and sends a Radio Bearer Reconfiguration Complete message to the RNC, so that the NC can learn that the UE has moved into the CELL FACH state;

 703. The RNC sends a first timer time length and a parameter N to the base station and the UE, where the parameter N is used by the base station and the UE to determine a predefined observation time point, where the predefined observation time point is pre-negotiated by the UE, the base station, and the RNC. Preferably, for example, the time in the SFN mode N=0 is used as a predefined observation time point, that is, the first timer is started when the SFN mode N=0 is satisfied. The time parameter N is fixed or configurable. The first timer and the parameter N are sent by the RNC to the UE through a dedicated RRC message (such as a radio bearer reconfiguration message). Correspondingly, the RNC notifies the base station of the first timer length and the parameter N through a dedicated FP frame or signaling. . Or the RNC sends the first timer time length and the parameter N to the UE through the system message. Correspondingly, the RNC notifies the base station of the first timer time length and the parameter N by using common signaling or a common FP frame.

 704. The base station and the UE determine a predefined observation time point according to the time parameter N.

 For example, a predefined observation time point is determined according to SFN mode N, and a time when SFN mode N=0 is satisfied is determined as a predefined observation time point.

 705. At a predefined observation time, the base station and the UE respectively start a first timer.

706. On the base station side, when the first timer is cut off, the base station determines that the UE moves into the CELL_PCH state when the first timer is cut off. Specifically, when the base station starts to send the downlink data to the UE before the time length of the first timer reaches the first preset time length, the base station restarts the first timer; otherwise, when the base station starts the first timer, the length of time reaches When the base station does not send downlink data to the UE again, the first timer expires.

 707. On the UE side, when the first timer is cut off, the UE moves to the CELL_PCH state when the first timer expires.

 Specifically, the UE restarts the first timer when the time when the UE starts the first timer reaches the first preset time length, and then receives the downlink data sent by the base station; otherwise, the time length of the UE starts the first timer. The first preset time length, when the UE does not receive the downlink data sent by the base station again, the first timer is cut off.

 The foregoing 706 and 707 are performed synchronously, and the technical solutions of the present invention are described on the base station side and the UE side, respectively.

 708. The base station sends an indication message to the RNC to notify the RNC that the UE moves into the CELL_PCH state.

 After the first timer expires, the base station notifies the RNC that the UE moves into the CELL_PCH state, and the RNC can update the state of the UE according to the received indication message. Thus, after the first timer is stopped, the base station receives HS-DSCH DATA FRAME TYPE2 and discards it.

 After receiving the indication message that the UE sends the CELL-PCH status to the base station, the RNC sends the data to the base station after the predefined time point to the current time. The FP frame needs to be reconstructed, that is, the HS-DSCH is constructed. DATA FRAME TYPE3 or notify high-level retransmissions such as the RLC layer or the RRC layer.

 709. After the UE moves into the CELL_PCH state, when uplink data is sent, the uplink data is directly sent to the base station.

 When the UE moves into the CELL-PCH state, after moving into the CELL-PCH state, the UE needs to monitor the PI at the paging occasion and then receive the downlink data.

The state transition method of this embodiment can achieve the UE by using the above technical solution. The seamless state transition between the CELL-FACH state and the CELL-PCH state, and no signalling participation during the state transition process, thereby effectively saving the signaling load of the network and saving network resources.
