Description

Network equipment, user equipment and state migration method

Technical Field

The present invention relates to the field of communications, and in particular, to a network device, a user equipment, and a state transition method.

Background

In an existing communication system, when the data amount of a User Equipment (UE) changes, the UE needs to perform state transition. For example, when the data amount of the UE in a CELL Forward Access Channel (CELL _ FACH) state is increased, the network side may determine, according to a measurement report reported by the UE, that the UE needs to be migrated from the CELL _ FACH state to a CELL Dedicated Channel (CELL _ DCH) state, and notify, to the UE, configuration information required when the UE migrates to the CELL _ DCH state through a signaling such as a Radio Bearer Reconfiguration (RBR) message, a Physical Channel Reconfiguration (Physical Channel Reconfiguration) message, a Transport Channel Reconfiguration (Transport Channel Reconfiguration) message, or a CELL Update confirmation (CELL Update confirmation) message, so that the UE migrates to the CELL _ DCH state according to the received configuration information.

In the process of realizing the state transition, at least the following problems exist: because the UE generally needs more configuration information for performing state transition, when the network side notifies the UE of the configuration information, signaling overhead is large, which causes waste of network resources.

For example, when the first state is the CELL _ FACH state, specifically, if the RNC determines that the data size of the UE increases according to the measurement report reported by the UE, it may be determined that the UE needs to be transitioned from the CELL _ FACH state to the CELL _ DCH state.

For example, when the network-side device is a NodeB, the NodeB may determine whether the UE needs to transition from the first state to the second state according to an indication of the RNC. For example: when the NodeB receives a radio link establishment request initiated by the RNC, the NodeB can determine that the UE needs to be transited from the first state to the second state, or when the NodeB receives indication information which is sent by the RNC and is used for common E-DCH configuration information of the UE, the NodeB determines that the UE needs to be transited from the first state to the second state. For the NodeB, the determination that the UE needs to transition from the first state to the second state is only to determine to subsequently send the state transition information to the UE, that is, the NodeB determines that the UE needs to transition from the first state to the second state, that is, the NodeB determines that the UE needs to send the state transition signaling to the UE.

It should be noted that, the indication information described in this embodiment of the present invention may be specifically configured to indicate that part of the configuration information when the UE is transitioned 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 configured to indicate that all the configurations when the UE is transitioned from the first state to the second state continue to adopt the configuration that the UE is in the first state, where the indication information specifically indicates that part of the configuration information when the UE is transitioned from the first state to the second state continues to adopt the configuration that the UE is in the first state, or indicates that all the configurations continue to adopt the configuration that the UE is in the first state, and may be set according to requirements of an actual application scenario, and this embodiment of the present invention is not limited specifically herein. When the indication information is used to indicate that part of the configuration information when the UE is transitioned from the first state to the second state continues to adopt the configuration that the UE is in the first state, the network device needs to also carry other configuration information, which is needed when the UE is transitioned to the second state, in the state transition signaling, and send the other configuration information to the UE.

In the state transition method provided by the embodiment of the present invention, the network device carries the indication information for indicating that the UE continues to adopt the configuration information that the UE is in the first state when the UE transitions from the first state to the second state in the state transition signaling and sends the state transition signaling to the UE, and compared with a mode that all the configuration information required after the UE transitions to the second state is carried in the state transition signaling and sent to the UE, the overhead of the state transition signaling is reduced, thereby saving network resources.

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

401. and the UE receives a state transition signaling which is sent by the network equipment and carries the indication information.

The indication information is used for indicating that the UE is in the configuration information of the first state when the UE is transferred 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. And the UE is configured according to the configuration information of the first state and transits to the second state.

For example, when the network side device is an RNC, the UE may periodically count its own traffic volume and report a traffic volume measurement report obtained by the statistics to the RNC, so that the RNC may determine whether the UE needs to be transitioned from the first state to the second state according to the traffic volume measurement report reported by the UE. Of course, the RNC may also determine whether the UE needs to be transitioned from the first state to the second state according to the downlink data amount of the UE.

For example, when the network-side device is a NodeB, the NodeB may determine whether the UE needs to transition from the first state to the second state according to an instruction of the RNC. For example: when the NodeB receives a radio link establishment request initiated by the RNC, the NodeB can determine that the UE needs to be transited from the first state to the second state, or when the NodeB receives indication information which is sent by the RNC and is used for common E-DCH configuration information of the UE, the NodeB determines that the UE needs to be transited from the first state to the second state. For the NodeB, the determination that the UE needs to transition from the first state to the second state is only to determine to subsequently send the state transition information to the UE, that is, the NodeB determines that the UE needs to transition from the first state to the second state, that is, the NodeB determines that the UE needs to send the state transition signaling to the UE.

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

The following description is presented to enable one skilled in the art to make and use the invention.

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

501. and the RNC determines that the UE needs to be transferred from the first state to the second state and sends a wireless link establishment 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 set up a Link between the RNC and the NodeB for the UE. Further, the RNC may carry indication information in the radio link setup request to indicate to the NodeB that the UE may reuse the configuration information of the common E-DCH (i.e., the resources of the common E-DCH). Preferably, the indication information may be a number of the common E-DCH resource. Further, in the link establishment procedure, the NodeB sends a radio link establishment response message to the RNC, where the radio link establishment 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 transmits resource holding instruction information to the UE.

Wherein, the resource keeping indication information is used for indicating the UE to keep keeping the resources of the common E-DCH in use, namely the UE does not execute the implicit release operation. Specifically, in order to avoid that the UE performs the 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 before the state transition, first send resource holding indication information to the UE, where the resource holding indication information indicates that the UE continues to hold the existing resource.

Wherein the resource keeping indication information can be contained in the HS-SCCH or the E-AGCH. For example: and the NodeB sends the HS-SCCH order or the E-AGCH order to the UE to indicate the UE to maintain the resources.

504. The UE receives the resource maintenance indication information transmitted by the NodeB.

505. The UE continues to maintain the existing resources.

After the UE receives the resource keeping indication information sent by the NodeB, the UE may continue to keep the resources of the common E-DCH that is being used according to the resource keeping indication information, and does not perform the implicit release operation.

Further, the operation that the UE does not perform the implicit resource release here means that when the condition of implicit resource release is satisfied, the UE does not send information buffered to zero to the NodeB and actively performs the release of the resource of the common E-DCH, or the UE sends information buffered to zero to the NodeB but does not release the resource of the corresponding common E-DCH.

506. And the RNC sends a 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 transition from the first state to the second state, the RNC sends the state transition signaling with indication information of configuration information for indicating that the UE is in the first state when the UE transitions from the first state to the second state, so that the UE completes the state transition. The state transition signaling may be Radio Resource Control (RRC) signaling.

Preferably, the indication information is used to indicate that all configuration information when the UE is transitioned from the first state to the second state adopts the 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 configuration information of a common E-DCH, configuration information of an HS-DSCH, configuration information of a common E-DCH and configuration information of an HS-DSCH. Generally, the common E-DCH configuration information in the first state corresponds to the E-DCH information in the second state, i.e., the configuration information used when the transport channel corresponding to the second state is the E-DCH.

The common E-DCH configuration information and the HS-DSCH configuration information may be configuration parameters carried in a system broadcast message, that is, the RNC transmits to the UE through the system broadcast message, or the RNC transmits to the UE through a dedicated RRC message. Specific examples of configuration information may include, but are not limited to: initial Grant, Transmission Time Interval (TTI) size, Hybrid Automatic Repeat request (HARQ) information for E-DCH, E-AGCH information, E-DCH Dedicated Physical Control Channel (E-DPCCH) information, E-DCH Dedicated Physical Data Channel (E-DPDCH) information, E-DCH Relative Grant Channel (E-RGCH) information, Measurement Feedback (Measurement Feedback) information, E-DCH HARQ Acknowledgement Indicator Channel (E-DCH HARQ Acknowledgement Indicator Channel, E-HICH) information, and HS-SCCH system information.

When the configuration information is the configuration information of the common E-DCH, the indication information may specifically be the number of the configuration information of the common E-DCH (the number of the configuration information of the common E-DCH may specifically be the resource number of the common E-DCH), 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 configuration information for a portion of the common E-DCH; the reuse indication may be a reuse indication of the configuration information of all common E-DCHs or a continuous use indication.

When the reuse indication is the reuse indication of the configuration information of the part of common E-DCH resources, the network equipment also comprises a parameter which can not be reused after the UE is migrated to the second state in the migration signaling. For example: the state transition signaling sent by the RNC to the UE comprises a reuse indication and also comprises E-AGCH information and E-RGCH information, and this indicates that in addition to the E-AGCH information and the E-RGCH information, other configuration information (related to resources of common E-DCH) which is not given and is used when the UE is in the first state can be continuously used when the UE transitions to the second state.

When the configuration information is configuration information of the HS-DSCH, the indication information may specifically be a reuse indication of the configuration information of the HS-DSCH. The reuse indication may be a reuse indication of configuration information of a partial HS-DSCH; the reuse indication may be a reuse indication of configuration information for all HS-DSCH as well as a continue use 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 specifically be the number of the configuration information of the common E-DCH, or the indication information is a reuse indication of the configuration information of the common E-DCH and the configuration information of the HS-DSCH; the reuse indication may represent a full reuse of the configuration information of the common E-DCH and the configuration information of the HS-DSCH; the reuse indication may also represent a partial reuse of the configuration information for the common E-DCH and the configuration information for the HS-DSCH. Because the reusable configuration information containing the common E-DCH and the HS-DSCH configuration information can be used, the network equipment can independently indicate whether each configuration information is reused, and the network equipment can also indicate that the common E-DCH configuration information and the HS-DSCH configuration information are reused through one indication information.

507. And the UE receives a state transition signaling which is sent by the RNC and carries the indication information.

After receiving the state transition signaling carrying the indication information sent by the RNC, the UE may perform configuration according to the indication information included in the state transition signaling, and transition to the second state by using the configuration information of the first state.

508. And the UE determines not to perform the synchronization process A or the synchronization process AA according to the indication information.

After receiving a state transition signaling carrying indication information sent by an RNC, if the RNC indicates that the RNC is in a second state, the UE continues to use configuration information that is being used when the RNC is in the first state, for example, configuration information of common E-DCH, at this time, the UE determines whether the timing when the UE transitions 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 a synchronization process a or a synchronization process AA, so that data transmission is not interrupted during the state transition process.

509. And the UE sends feedback information to the RNC.

The feedback information is used for feeding back that the UE has correctly received the state transition signaling, or the feedback information is used for feeding back that the UE has transitioned to the second state. The feedback information may be RRC signaling or HARQ acknowledgement feedback.

In a first possible implementation manner in the embodiment of the present invention, after the UE correctly receives the state transition signaling carrying the indication information sent by the RNC, the UE may send feedback information for feeding back the state transition signaling that the UE correctly received the state transition signaling sent by the UE to the RNC.

In a second possible implementation manner in the embodiment of the present invention, after receiving a state transition signaling carrying indication information and sent by an RNC, the UE may further transition from a first state to a second state according to the received state transition signaling, and after successfully transitioning to the second state, send feedback information for feeding back that the UE has transitioned to the second state to the RNC.

It should be noted that, in the embodiment of the present invention, there is no sequence between the execution of step 508 and the execution of step 509, that is, after step 507 is executed to receive the state transition signaling carrying the indication information sent by the RNC, step 508 may be executed first, and then step 509 is executed; step 509 may be performed first, and then step 508 may be performed; of course, step 508 and step 509 may also be performed simultaneously. The specific execution sequence of steps 508 and 509 may be selected according to the requirement of an actual application scenario, and the embodiment of the present invention is not limited in this respect.

510. And the RNC receives the feedback information sent by the UE.

It should be noted that, for the specific description of steps 501 to 510 in the embodiment of the present invention, reference may be made to the specific description of corresponding contents in steps 301 to 302 in another embodiment of the present invention, and details of the embodiment of the present invention are not repeated herein.

In the state transition method provided by the embodiment of the present invention, the RNC carries the indication information for indicating that the UE continues to adopt the configuration information that the UE is in the first state when the UE transitions from the first state to the second state in the state transition signaling and sends the state transition signaling to the UE, and compared with a mode that all the configuration information required after the UE transitions to the second state is carried in the state transition signaling and sent to the UE, the RNC reduces the overhead of the state transition signaling, thereby saving network resources.

Another embodiment of the present invention provides a state transition method, and in the embodiment of the present invention, a network device is taken as a NodeB for example, as shown in fig. 8, the method may include:

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

602. The NodeB transmits resource holding instruction information to the UE.

The resource keeping indication information is used for indicating the UE to keep the existing resources, that is, the UE does not execute the implicit release operation according to the resource indication information.

603. The UE receives the resource maintenance indication information transmitted by the NodeB.

604. The UE continues to maintain the existing resources.

605. The NodeB determines that the UE needs to transition from the first state to the second state.

For example, the NodeB may determine whether the UE needs to transition from the first state to the second state according to the indication of the RNC. For example: when the NodeB receives a radio link establishment request initiated by the RNC, the NodeB can determine that the UE needs to be transited from the first state to the second state, or when the NodeB receives indication information which is sent by the RNC and is used for common E-DCH configuration information of the UE, the NodeB determines that the UE needs to be transited from the first state to the second state. For the NodeB, the only way to determine that the UE needs to transition from the first state to the second state is to subsequently send state transition information to the UE, that is, the NodeB determines that the UE needs to transition from the first state to the second state, that is, the NodeB determines that the UE needs to send state transition signaling to the UE

606. And the NodeB sends a state transition signaling carrying the indication information to the UE.

The indication information is used for indicating that the UE is in the configuration information of the first state when the UE is transferred from the first state to the second state. And the state transition signaling may specifically be control signaling of the physical layer, for example, HS-SCCH order, or E-AGCH order. Preferably, the indication information is common E-DCH configuration information and/or HS-DSCH configuration information full reuse indication.

607. And the UE receives a state transition signaling which is sent by the NodeB and carries the indication information.

608. And the UE determines not to perform the synchronization process A or the synchronization process AA according to the indication information.

609. And the UE sends feedback information to the NodeB.

The feedback information is used for feeding back that the state transition signaling is correctly received by the feedback information, or the feedback information is used for feeding back that the state transition signaling is transitioned to the second state.

It should be noted that, in the embodiment of the present invention, the execution of step 608 and step 609 does not have a sequence, that is, after step 607 is executed to receive the state transition signaling carrying the indication information sent by the NodeB, step 608 may be executed first, and then step 609 is executed; step 609 may be performed first, and then step 608 is performed; of course, step 608 and step 609 may also be performed simultaneously. The specific execution sequence of step 608 and step 609 may be selected according to the requirement of an actual application scenario, and the embodiment of the present invention is not limited in this respect.

610. And the NodeB receives the feedback information sent by the UE.

It should be noted that, for the specific description of steps 601 to 610 in the embodiment of the present invention, reference may be made to the specific description of corresponding contents in steps 501 to 510 in another embodiment of the present invention, and details of the embodiment of the present invention are not repeated herein.

In the state transition method provided in the embodiment of the present invention, the NodeB carries the indication information for indicating that the UE continues to use the configuration information of the UE in the first state when transitioning from the first state to the second state in the state transition signaling and sends the indication information to the UE, and compared to a manner in which all the configuration information required after the UE transitions to the second state is carried in the state transition signaling and sent to the UE, the method reduces overhead of the state transition signaling, thereby saving network resources.

It should be noted that, when the network device is a physical entity device that integrates the functions of the RNC and the NodeB, the steps 601 to 610 of the embodiment of the present invention may be referred to in the specific implementation process of the present invention. The difference is that the main body for executing each step is a physical entity device integrating the function of the RNC and the function of the NodeB, and the detailed description of the present invention is omitted here.
