It should be noted that the network device in the embodiment of the present invention may be an RNC or a NodeB, or may be a physical entity device that integrates the functions of the RNC and the functions of the NodeB.

Exemplarily, when the network device is an RNC, the RNC may determine whether the UE needs to migrate from the first state to the second state according to the measurement report reported by the UE, or determine whether the UE needs to be from the first according to the downlink data volume of the UE. A state transitions to a second state. For example, when the first state is the CELL_FACH state, the RNC may determine that the UE needs to migrate from the CELL_FACH state to the CELL_DCH state, if the RNC determines that the data volume of the UE is increased according to the measurement report reported by the UE.

Exemplarily, when the network side device is a NodeB, the NodeB may determine, according to an indication of the RNC, whether the UE needs to migrate from the first state to the second state. For example, when the NodeB receives the radio link setup request initiated by the RNC, the NodeB may determine that the UE needs to migrate from the first state to the second state, or when the NodeB receives the configuration information of the common E-DCH sent by the RNC to the UE. When the indication information is reused, it is determined that the UE needs to migrate from the first state to the second state. For the NodeB, the determining that the UE needs to migrate from the first state to the second state is only for determining that the state transition information is subsequently sent to the UE, that is, the NodeB determines that the UE needs to migrate from the first state to the second state, that is, The NodeB determines that state transition signaling needs to be sent to the UE.

It should be noted that the indication information in the embodiment of the present invention may be specifically configured to indicate that part of the configuration information when the UE migrates from the first state to the second state continues to adopt the configuration that the UE is in the first state, and may also be used. All the configurations when the UE is instructed to migrate from the first state to the second state continue to adopt the configuration that the UE is in the first state, and the indication information is specifically indicating that the UE migrates from the first state to the second state to continue to adopt the UE. The configuration in the first state is a configuration in which the configuration of the UE is in the first state, and the configuration of the UE is in the first state, and may be set according to the requirements of the actual application scenario. Wherein, when the indication information is used to indicate that the part of the configuration information when the UE migrates from the first state to the second state continues to adopt the configuration in which the UE is in the first state, the network device further needs to migrate the UE except the partial configuration information to Other configuration information required for the second state is also carried in the state transition signaling and sent to the UE.

According to the state transition method provided by the embodiment of the present invention, the network device sends, to the state transition signaling, the indication information that is used to continue to adopt the configuration information that the UE is in the first state when the UE migrates from the first state to the second state. The UE reduces the overhead of the state transition signaling, and saves the network resources, as compared with the manner in which the configuration information required after the UE is migrated to the second state is all carried in the state transition signaling to the UE.

Another embodiment of the present invention provides a state transition method. As shown in FIG. 6, the method may include:

401. The UE receives state transition signaling that is sent by the network device and carries the indication information.

The indication information is used to indicate that the UE adopts configuration information that the UE is in the first state when transitioning from the first state to the second state. The first state may be a CELL_FACH state or a CELL_PCH state, and the second state may be a CELL_DCH state.

402. The UE is configured in the first state configuration information, and migrates to the second state.

Exemplarily, when the network side device is an RNC, the UE may periodically collect statistics on its own traffic, and report the obtained traffic measurement report to the RNC, so that the RNC can determine according to the traffic measurement report reported by the UE. Whether the UE needs to migrate from the first state to the second state. Of course, the RNC may also determine whether the UE needs to migrate from the first state to the second state according to the downlink data volume of the UE.

Exemplarily, when the network side device is a NodeB, the NodeB may determine, according to an indication of the RNC, whether the UE needs to migrate from the first state to the second state. For example, when the NodeB receives the radio link setup request initiated by the RNC, the NodeB may determine that the UE needs to migrate from the first state to the second state, or when the NodeB receives the configuration information of the common E-DCH sent by the RNC to the UE. When the indication information is reused, it is determined that the UE needs to migrate from the first state to the second state. For the NodeB, here, it is determined that the UE needs to migrate from the first state to the second state only to determine subsequent to the UE. The state transition information is sent, that is, the NodeB determines that the UE needs to migrate from the first state to the second state, that is, the NodeB determines that the state transition signaling needs to be sent to the UE.

According to the state transition method provided by the embodiment of the present invention, the UE receives state transition signaling sent by the network device and carries indication information indicating that the UE is in the first state when the UE migrates to the second state, compared to Receiving the state transition signaling sent by the network device and carrying all the configuration information required after the UE migrates to the second state, the overhead of the state transition signaling is reduced, thereby saving network resources.

In order to facilitate the understanding of those skilled in the art, the implementation process of the present invention will be specifically described below.

Another embodiment of the present invention provides a state transition method, and in the embodiment of the present invention, the network device is taken as an example of the RNC. As shown in FIG. 7, the method may include:

501. The RNC determines that the UE needs to migrate from the first state to the second state, and sends a radio link setup request of the UE to the NodeB.

The first state may be a CELL_FACH state or a CELL_PCH state; the second state may be a CELL_DCH state.

The radio link setup request (Radio Link Setup Request) sent by the RNC to the NodeB is used to establish a link between the RNC and the NodeB for the UE. Further, the RNC may carry the indication information in the radio link setup request to indicate to the NodeB that the UE can perform the reuse of the configuration information of the common E-DCH (ie, the resource of the common E-DCH). Preferably, the indication information may be a number of a common E-DCH resource. Further, in the link establishment process, the NodeB sends a radio link setup response message to the RNC, where the radio link setup response message includes the resource number of the common E-DCH used by the UE. Preferably, the radio link setup response information may further include configuration information of the F-DPCH.

502. The NodeB determines that the UE is using the configuration information of the common E-DCH.

The configuration information of the common E-DCH is specifically a resource of the common E-DCH.

503. The NodeB sends the resource hold indication information to the UE.

The resource hold indication information is used to indicate that the UE continues to maintain the resources of the common E-DCH that is being used, that is, the UE does not perform an implicit release operation. Specifically, in order to prevent the UE from performing a resource release operation during the state transition, the NodeB may determine that the UE is using the configuration information of the common E-DCH, that is, the resource of the common E-DCH, and perform state transition in the UE. Previously, resource hold indication information for indicating that the UE continues to maintain an existing resource is sent to the UE.

The resource hold indication information may be included in the HS-SCCH or in the E-AGCH. For example, the NodeB sends an HS-SCCH order or an E-AGCH order to the UE to instruct the UE to maintain the resource.

504. The UE receives the resource retention indication information sent by the NodeB.

505. The UE continues to maintain existing resources.

After receiving the resource hold indication information sent by the NodeB, the UE may continue to maintain the resources of the common E-DCH being used according to the resource hold indication information, and does not perform an implicit release operation.

Further, the operation of the UE not performing the implicit resource release means that the UE does not send the information with zero buffer to the NodeB and actively releases the resources of the common E-DCH, or the UE, when the condition of the implicit resource release is satisfied. The information with zero buffer is sent to the NodeB, but the UE does not release the resources of the corresponding common E-DCH.

506. The RNC sends state transition signaling carrying the indication information to the UE.

In order to reduce the overhead of the state transition signaling, after the RNC determines that the UE needs to migrate from the first state to the second state, the RNC is used to indicate that the UE is in the first state when migrating from the first state to the second state. The indication information of the configuration information of the state is carried in the state transition signaling and sent to the UE, so that the UE completes the migration of the state. The state transition signaling may be Radio Resource Control (RRC) signaling.

Preferably, the indication information is used to indicate that all configuration information of the UE transitioning from the first state to the second state adopts configuration information that the UE is in the first state.

The configuration information used by the UE in the first state in the embodiment of the present invention may be the configuration information of the common E-DCH, the configuration information of the HS-DSCH, and the configuration information of the common E-DCH and the HS. -DSCH configuration information. Pass Normally, the configuration information of the common E-DCH in the first state corresponds to the E-DCH information in the second state, that is, the configuration information used when the transport channel corresponding to the second state is the E-DCH.

The configuration information of the common E-DCH and the configuration information of the HS-DSCH may be the configuration parameters carried in the system broadcast message, that is, the RNC sends the message to the UE through the system broadcast message, or the RNC sends the message to the UE through the dedicated RRC message. of. The configuration information may include, but is not limited to, an initial authorization, a Transmit Time Interval (TTI), an Hybrid Automatic Repeat Request (HARQ) information, an E-AGCH information, and an E-DCH. -DCH Dedicated Physical Control Channel (E-DPCCH) information, E-DCH Dedicated Physical Data Channel (E-DPDCH) information, E-DCH relative grant channel (E-DCH) E-DCH Relative Grant Channel (E-RGCH) information, measurement feedback information, E-DCH HARQ Acknowledgement Indicator Channel (E-HICH) information, HS-SCCH system information.

The resource number), or, may also be a reuse indication of the configuration information of the common E-DCH. The reuse indication may be a reuse indication of the configuration information of the part of the common E-DCH; the reuse indication may also be a reuse indication of the configuration information of all the common E-DCHs, and may also be an indication of continued use.

When the re-use indication indicating the configuration information of the part of the common E-DCH resource is reused, the network device further includes, in the migration signaling, a parameter that cannot be reused after the UE migrates to the second state. For example, the state transition signaling sent by the RNC to the UE includes a re-use indication, and also includes E-AGCH information and E-RGCH information, indicating that the E-AGCH information and the E-RGCH information are not given. Configuration information that is used when the UE is in the first state (resource related to common E-DCH) It can continue to be used when the UE migrates to the second state.

When the configuration information is the configuration information of the HS-DSCH, the indication information may specifically be a re-use indication of the configuration information of the HS-DSCH. The reuse indication may be a reuse indication of the configuration information of the partial HS-DSCH; the reuse indication may also be a reuse indication of configuration information of all HS-DSCHs, or may be a continuation indication.

When the configuration information is the configuration information of the common E-DCH and the configuration information of the HS-DSCH, the indication information may be the number of the configuration information of the common E-DCH, or the indication information is the configuration information of the common E-DCH and a reuse indication of the configuration information of the HS-DSCH; the reuse indication may indicate all reuse of the configuration information of the common E-DCH and the configuration information of the HS-DSCH; the reuse indication may also indicate the configuration information of the common E-DCH and the HS-DSCH Partial reuse of configuration information. The network device can separately indicate whether each configuration information is reused due to the reusable configuration information including the common E-DCH configuration information and the HS-DSCH configuration information, and the network device can also indicate the configuration information of the common E-DCH and the HS through an indication information. - DSCH configuration information is reused.

After the UE receives the state transition signaling carrying the indication information sent by the RNC, if the RNC indicates that it is migrating to the second state, it continues to use the configuration information that is being used when it is in the first state, for example, common E - configuration information of the DCH. At this time, the UE determines whether the timing when migrating to the second state needs to be adjusted according to the indication information in the state transition signaling, and if the timing does not need to be adjusted, the UE determines not to perform the synchronization process A or the synchronization process. AA, so data transfer does not occur during state transitions.

509. The UE sends feedback information to the RNC.

The feedback information is used to feedback that the UE itself has correctly received the state transition letter. Alternatively, or the feedback information is used to feedback that the UE itself has migrated to the second state. The feedback information may be RRC signaling or HARQ acknowledgment feedback.
