Background
When a User Equipment (UE) in a non-CELL Dedicated Channel state (CELL-DCH) reselects a CELL, a system broadcast message of the CELL is acquired, and if the UE needs to send data in the CELL, the UE needs to first acquire a system broadcast message required for initiating random access, such as a System Information Block (SIB) 3 and a SIB5, and if the UE needs to acquire more SIB blocks, the required time is longer, and the sending of uplink data of the UE is delayed.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The random access processing method provided by the embodiment of the invention can be suitable for a scene that UE needs to acquire part or all of system broadcast messages before reselecting to a new cell to initiate random access, and is also suitable for a scene that UE needs to acquire part or all of system broadcast messages again before an original cell initiates random access.
Fig. 1 is a flowchart of a random access processing method according to a first embodiment of the present invention. As shown in fig. 1, an execution main body of the random access processing method provided in this embodiment is a UE, and the random access processing method provided in this embodiment may include:
s101, the UE determines that the first system information block is read in a delaying mode.
In a specific application process, the UE receives a delayed reading indication message sent by a Radio Network Controller (RNC), where the delayed reading indication message is used to indicate that the UE initiates a random access process before reading a first system information block, specifically, the first system information block may be SIB22, or may be another system information block, which is not limited in this embodiment.
It should be noted that the delayed read indication message may be included in a second system Information Block, where the second system Information Block is different from the first system Information Block, and specifically, the second system Information Block may be a Master Information Block (MIB), a Master Information Block (SIB 5), or another system Information Block, which is not limited in this embodiment; or, the delayed reading indication message may also be pre-stored in the UE, that is, the UE agrees with the network side, and before the random access, the UE may not acquire the first system information block, which is not limited in this embodiment.
The first system information block not acquired means that the UE, which can originally recognize the content of the first system information block, cannot recognize the configuration information included in the valid first system information block due to reasons such as that the UE does not receive all scheduling blocks of the first system information block or incorrect configuration on the network side.
S102, the UE initiates random access before acquiring the first system information block.
In an actual application process, after the UE determines that the first system information block is read in a delayed manner, the UE may initiate random access before acquiring the first system information block, and at this time, the UE initiates random access by using the random access parameter configured in the second system information block to acquire a resource for data transmission.
Further, the second system information block includes at least a portion of the configuration information of the first system information block.
Optionally, after the UE initiates random access to obtain resources, the UE may send a request message to the RNC, where the request message includes indication information that the UE does not acquire the first system information block, and after the UE sends the request message to the RNC, the UE receives a response message sent by the RNC, where the response message includes at least a part of configuration information of the first system information block.
Those skilled in the art can understand that the response message may not include at least a part of the configuration information of the first system information block, and in this case, the UE does not need to use at least a part of the configuration information in the first system information block and use the sub-characteristic corresponding to the configuration information before acquiring the first system information block.
Further, if the UE initiates a random access procedure before acquiring the first system information block, the UE may still continue to acquire the system information block in the random access procedure, or in the data transmission procedure, or in the data reception waiting procedure.
It should be noted that the Request message may be a Radio Resource Control (RRC) Connection Request (RRC Connection Request), and correspondingly, the response message is an RRC Connection setup (RRC Connection setup); the request message may also be a Cell Update (Cell Update), and correspondingly, the response message is a Cell Update Confirm (Cell Update Confirm); the request message may also be a UTRAN registration area Update (URA Update) and correspondingly the response message is a UTRAN registration area Update Confirm (URA Update Confirm).
Further, when the first system information block is SIB22, the at least part of the configuration information may include at least one of the following configuration information: base station triggered HS-DPCCH transmission (NodeB triggered HS-DPCCH Transmission), fallback to R99 (fallback to R99 PRACH), enhanced discontinuous reception (HS-DSCH DRX _ FACH with second DRX cycle), coexistence of2ms and10ms transmission time intervals (ConcurrentDeployment of2ms and10ms TTI).
Alternatively, when the first system information block is SIB22, after the UE initiates random access, the UE may detect a high speed shared control channel order (HS-SCCH order) before acquiring SIB22 to use the base station triggered HS-DPCCH transmission characteristics according to the detected high speed shared control channel order.
Optionally, the second system information block includes at least a part of configuration information of the first system information block. After the UE initiates random access, the UE adopts at least part of configuration information of the first system information block acquired from the second system information block. Specifically, when the first system information block is SIB22, the at least part of the configuration information may include at least one of the following configuration information: the base station triggered HS-DPCCH transmission falls back to R99, enhanced discontinuous reception, and 2ms and10ms transmission time intervals coexist.
In the random access processing method provided in this embodiment, the UE determines that the first system information block is delayed to be read, and the UE may initiate random access before acquiring the first system information block, so that the UE may quickly access after reselecting to a new cell, and send uplink data, and the UE may acquire at least part of configuration information in the first system information block before acquiring the first system information block by including at least part of configuration information of the first system information block in a downlink message, so that the UE may use at least part of configuration information in the first system information block and use a sub-characteristic corresponding to the configuration information before acquiring the first system information block.
Fig. 2 is a flowchart of a second embodiment of a random access processing method of the present invention. As shown in fig. 2, an execution main body of the random access processing method provided in this embodiment is an RNC, and the random access processing method provided in this embodiment may include:
s201, the RNC generates a delay reading indication message, wherein the delay reading indication message is used for indicating the UE to initiate a random access process before the UE does not read the first system information block.
It should be noted that the delayed reading indication message may be contained in a second system information block, where the second system information block is a different system information block from the first system information block, specifically, the second system information block may be an MIB, an SIB5, or another system information block, which is not limited in this embodiment; or, the delayed reading indication message may also be pre-stored in the UE, that is, the network side and the UE agree, and before the random access, the UE may not acquire the first system information block, which is not limited in this embodiment.
S202, the RNC sends the delayed reading indication message to the UE, so that the UE can initiate random access before acquiring the first system information block according to the delayed reading indication message.
In the practical application process, after the RNC sends the delay reading indication message to the UE, the UE initiates random access before acquiring the first system information block according to the delay reading indication message, and at this time, the UE may initiate random access by using the random access parameter configured in the second system information block to acquire the resource for data transmission.
Further, at least a portion of the configuration information of the first system information block may be included in the second system information block.
Optionally, after the RNC sends the delay reading indication message to the UE, the RNC receives a request message sent by the UE, where the request message includes indication information that the UE does not acquire the first system information block, and after receiving the request message, the RNC sends a response message to the UE, where the response message includes at least part of configuration information of the first system information block.
It should be noted that the request message may be an RRC connection request, and correspondingly, the response message is RRC connection establishment; the request message may be a cell update, and correspondingly, the response message is a cell update confirmation; the request message may also be a UTRAN registration area update, and correspondingly, the response message is a UTRAN registration area update confirm.
Further, when the first system information block is SIB22, the at least part of the configuration information may include at least one of the following configuration information: the base station triggered HS-DPCCH transmission falls back to R99, enhanced discontinuous reception, and 2ms and10ms transmission time intervals coexist.
Optionally, when the RNC sends the delayed reading indication message to the UE, the RNC sends a second system information block to the UE, where the second system information block includes at least a part of the configuration information of the first system information block, so that the UE obtains at least a part of the configuration information of the first system information block from the second system information block. Specifically, when the first system information block is SIB22, the at least part of the configuration information may include at least one of the following configuration information: the base station triggered HS-DPCCH transmission falls back to R99, enhanced discontinuous reception, and 2ms and10ms transmission time intervals coexist.
Optionally, after the RNC sends the delay reading indication message to the UE, the RNC may determine that the UE has acquired the first system information block according to the access time of the UE and the scheduling time of the SIB, and execute an operation of the parameter corresponding to the first system information block after the RNC determines that the UE has acquired the first system information block. When the first system information block is SIB22, the RNC may indicate to the NodeB that the UE supports the base station-triggered HS-DPCCH transmission characteristic, or indicate to the NodeB that the UE supports the enhanced discontinuous reception characteristic.
Optionally, when the first system information block is SIB22, when the RNC sends the delayed read indication message to the UE, the RNC may set the value of an implicit resource release timer of the common enhanced dedicated transport channel and the value of an implicit resource release timer corresponding to the HS-DPCCH transmission triggered by the base station to be the same, where the implicit resource release timer of the common enhanced dedicated transport channel is the second system information block, that is: the SIB5 includes configuration information, and an implicit resource release timer corresponding to HS-DPCCH transmission triggered by the base station is configuration information included in the first system information block, and the RNC sets the value of the implicit resource release timer in the second system information block to be the same as the value of the implicit resource release timer in the first system information block, so that after the UE acquires the value of the implicit resource release timer in the second system information block, the UE may acquire the value of the implicit resource release timer in the first system information block, that is, after the UE reads the delayed reading indication information, the UE may use the value of the implicit resource release timer of the common enhanced dedicated transport channel in the second system information block to replace the value of the implicit resource release timer in the first system information block.
In the random access processing method provided in this embodiment, the RNC generates the delayed reading indication message to indicate the UE to initiate a random access process before the UE does not read the first system information block, and the RNC sends the delayed reading indication message to the UE to enable the UE to initiate a random access before the UE acquires the first system information block, so that the UE can access the new cell faster after reselecting the new cell, and send uplink data, and the UE can use at least a part of configuration information in the first system information block and use a sub-characteristic corresponding to the configuration information before acquiring the first system information block by including at least a part of configuration information in the first system information block in the downlink message.
The following describes the random access processing method according to an embodiment of the present invention in detail.
Fig. 3 is a signaling flowchart of a third embodiment of a random access processing method of the present invention. As shown in fig. 3, the random access processing method provided in this embodiment may include:
s301, the RNC sends a delay reading indication message to the UE.
S302, the UE sends a request message to the RNC.
S303, the RNC sends a response message to the UE.
In this embodiment, the first system information block is SIB22, and the second system information block is SIB 5.
In an actual application process, if the UE supports the subfeatures of the FE-FACH in the reselected cell, the SIB22 needs to be acquired, and at this time, after the UE acquires the delayed reading indication message, the UE may initiate random access before acquiring the SIB 22.
It should be noted that the present embodiment includes two implementation scenarios: the first scenario is that the UE has acquired SIB22 when receiving the delayed read indication message; the second scenario is that the UE does not acquire the SIB22 when it receives the delayed read indication message.
In the first scenario, the UE may initiate random access according to its own capabilities and the random access parameters configured in SIB 22.
In the second scenario, after receiving the delayed reading indication message, the UE may initiate random access using the random access parameter configured in SIB5, and after initiating random access, the UE sends a request message to the RNC, where the request message includes indication information that the UE does not acquire SIB 22. After receiving the request message, the RNC parses the non-acquisition SIB22 indication message, and at this time, in order to enable the UE to use at least a part of configuration information of SIB22, such as HS-DPCCH transmission triggered by the base station, fall back to R99, enhanced discontinuous reception, and coexistence of2ms and10ms transmission time intervals, when not acquiring SIB22, the RNC may use any feasible implementation manner provided later in this embodiment.
In a first possible implementation manner, the RNC sends a response message to the UE, where the response message includes at least a part of the configuration information of SIB22, so that the UE can use the sub-characteristics of the FE-FACH corresponding to at least a part of the configuration information in SIB22 before acquiring SIB 22.
In a second possible implementation manner, after the RNC sends the delay reading indication message to the UE, the RNC determines that the UE has acquired SIB22 according to the access time of the UE and the scheduling time of SIB22, specifically, the access time of the UE is the time when the UE initiates uplink transmission, and the scheduling time of SIB22 is the time when SIB22 is issued. After the RNC determines that the UE acquires the SIB22, the RNC can indicate to the NodeB that the UE supports the HS-DPCCH transmission triggered by the base station, or indicate to the NodeB that the UE supports the enhanced discontinuous reception characteristic, and the NodeB can issue an HS-SCCH order after receiving the indication message, so that the UE uses the HS-DPCCH transmission characteristic triggered by the base station.
In a third possible embodiment, when the RNC sends a delayed read indication message to the UE, the RNC may set the value of the implicit resource release timer for the common enhanced dedicated transport channel and the value of the implicit resource release timer corresponding to the base station triggered HS-DPCCH transmission to be the same, since the implicit resource release timer for the common enhanced dedicated channel is the configuration information in SIB5, the implicit resource release timer corresponding to the HS-DPCCH transmission triggered by the base station is the configuration information in the SIB22, the values of the two implicit resource release timers are set to be the same, as long as the UE acquires the SIB5, the value is equivalent to the value of the implicit resource release timer of the configuration information in the SIB22, at this time, the UE detects the high-speed shared control channel command before acquiring the SIB22, to use the base station triggered HS-DPCCH transmission characteristics according to the detected high speed shared control channel order.
In a fourth possible embodiment, when the RNC sends the delayed reading indication message to the UE, the RNC includes at least a part of the configuration information of SIB22 in SIB5, so that the UE acquires at least a part of the configuration information of SIB22 from SIB 5. Optionally, for the HS-DPCCH transmission characteristic triggered by the base station, in order to reduce the content added in the SIB5, the RNC may also include the indication information of the characteristic in the SIB5, and the implicit resource release timer information uses the information of the implicit resource release timer in the SIB 5. Alternatively, for the feature of fallback to R99, in order to reduce the content added in SIB5, the RNC may only fallback to a Common Control Channel (CCCH) or only fallback to a Dedicated Control Channel (DCCH) in SIB 5.
It should be noted that the request message may be an RRC connection request, and correspondingly, the response message is RRC connection establishment; or, the request message may be a cell update, and correspondingly, the response message is a cell update confirmation; alternatively, the request message may be a UTRAN registration area update, and the response message may be a UTRAN registration area update confirmation.
In the random access processing method provided in this embodiment, a delay reading indication message is sent to the UE by the RNC, the UE sends a request message to the RNC, and the RNC sends a response message to the UE, so that the UE can access the UE faster after reselecting to a new cell, and send uplink data.
Fig. 4 is a schematic structural diagram of a UE according to a first embodiment of the present invention. As shown in fig. 4, the UE provided in this embodiment may include: a determining module 11 and a random access initiating module 12.
Wherein the determining module 11 is configured to determine that the first system information block is delayed to be read;
the random access initiating module 12 is configured to initiate random access before acquiring the first system information block.
It should be noted that the determining module 11 may be specifically configured to receive a delayed reading indication message sent by the RNC, where the delayed reading indication message is used to indicate that a random access procedure is initiated before the first system information block is not read.
Specifically, the first system information block may be the SIB22, or may be another system information block, which is not limited in this embodiment.
Further, the delayed read indication message may be contained in a second system information block, where the second system information block is a different system information block from the first system information block, and optionally, the second system information block may be an MIB, an SIB5, or another system information block, which is not limited in this embodiment; or, the delayed reading indication message may also be pre-stored in the UE, that is, the UE agrees with the network side, and before the random access, the UE may not acquire the first system information block, which is not limited in this embodiment.
The first system information block not acquired means that the UE, which is originally capable of identifying the content of the first system information block, cannot identify the configuration information included in the valid first system information block due to reasons such as that the UE does not receive all scheduling blocks of the first system information block, or due to incorrect configuration on the network side.
In an actual application process, after the UE determines that the first system information block is read in a delayed manner, the UE may initiate random access before acquiring the first system information block, and at this time, the UE initiates random access by using the random access parameter configured in the second system information block to acquire a resource for data transmission.
The UE provided in this embodiment may be used to execute the technical solution of the method embodiment shown in fig. 1, and the principle and technical effect are similar, which are not described herein again.

The generating module 21 is configured to generate a delayed reading indication message, where the delayed reading indication message is used to indicate that a user equipment UE initiates a random access procedure before a first system information block is not read;
the indication message sending module 22 is configured to send a delayed reading indication message to the UE, so that the UE initiates random access before acquiring the first system information block according to the delayed reading indication message.
It should be noted that the delayed reading indication message may be contained in a second system information block, where the second system information block is a different system information block from the first system information block, specifically, the second system information block may be an MIB, an SIB5, or another system information block, which is not limited in this embodiment; or, the delayed reading indication message may also be pre-stored in the UE, that is, the network side and the UE agree, and before the random access, the UE may not acquire the first system information block, which is not limited in this embodiment.
In the practical application process, after the RNC sends the delay reading indication message to the UE, the UE initiates random access before acquiring the first system information block according to the delay reading indication message, and at this time, the UE may initiate random access by using the random access parameter configured in the second system information block to acquire the resource for data transmission.
The RNC provided in this embodiment may be used to implement the technical solution of the method embodiment shown in fig. 2, and the principle and technical effect are similar, which are not described herein again.

Wherein the processor 31 is configured to determine that the first system information block is delayed for reading;
the transmitter 32 is arranged to initiate random access prior to acquiring the first system information block.
It should be noted that the processor 31 may be specifically configured to receive a delayed reading indication message sent by the RNC, where the delayed reading indication message is used to indicate that a random access procedure is initiated before the first system information block is not read.
Specifically, the first system information block may be the SIB22, or may be another system information block, which is not limited in this embodiment.
Further, the delayed read indication message may be contained in a second system information block, where the second system information block is a different system information block from the first system information block, and optionally, the second system information block may be an MIB, an SIB5, or another system information block, which is not limited in this embodiment; or, the delayed reading indication message may also be pre-stored in the UE, that is, the UE agrees with the network side, and before the random access, the UE may not acquire the first system information block, which is not limited in this embodiment.
The non-acquisition of the first system information block means that the UE, which is originally capable of identifying the content of the first system information block, cannot identify the configuration information included in the valid first system information block due to reasons such as the fact that the UE does not receive all scheduling blocks of the first system information block or the reason of wrong configuration on the network side.
In an actual application process, after the UE determines that the first system information block is read in a delayed manner, the UE may initiate random access before acquiring the first system information block, and at this time, the UE initiates random access by using the random access parameter configured in the second system information block to acquire a resource for data transmission.
