Definitions
- the present invention relates to a random access technology, and in particular, to a radio resource control connection re-establishment triggering method and apparatus. Background technique
- radio resource control connection state downlink data arrival requires a random access procedure, for example, when the uplink synchronization state is "unsynchronized”"Time
- radio resource control connection status uplink data arrival requires a random access procedure, for example, when the uplink synchronization status is "unsynchronized” or there is no physical uplink control channel (PUCCH, Physical Uplink Control Channel) resource transmission scheduling request (SR, Schedule Request))
- the radio resource control connection status requires a random access procedure for positioning purposes. For example, UE positioning requires Timing Advance.
- the random access procedure is divided into two types: a contention-based random access procedure and a non-contention-based random access procedure.
- the RRC layer of the UE When receiving the foregoing indication by the MAC layer, the RRC layer of the UE considers that the radio link failure (RLF, Radio Link Failure) is detected in the access layer when the timers T300, ⁇ 301, ⁇ 304, and T311 are not running.
- RLF Radio Link Failure
- AS Access Stratum
- the start and stop conditions of the above timers are listed in the table of Section 7.3 of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) protocol specification TS36.331.
- the T300 is used when the UE in the radio resource control idle state (RRC_IDLE) initially accesses the network, and is started when the radio resource control connection request message (RRCConnectionRequest) is sent.
- RRC_IDLE radio resource control idle state
- RRCConnectionRequest radio resource control connection request message
- the UE chooses to initiate random access only on the UL PCC. If the random access fails to reach the maximum number of times, the MAC layer indicates that there is a problem in the RRC layer random access; or the UE chooses to initiate a random access procedure on any UL CC, if the random access is performed.
- the MAC address indicates that there is a problem in the RRC layer random access; the above two methods are consistent with the corresponding methods in the LTE system.
- the UE The random access fails to reach the maximum number of times on a certain UL CC, and then attempts to initiate random access on other UL CCs until the maximum number of random accesses of all UL CCs is reached.
- the MAC layer indicates that the RRC layer is randomly connected. If there is a problem, this method does not consider the radio conditions of the UL CC, the RACH resource configuration, the delay, the selection method of the UL CC, and whether the UL CC can be repeatedly selected. Summary of the invention
- a radio resource control connection re-establishment triggering method which sets a random access policy for a UE; the method includes:
- the set uplink component carrier includes a primary uplink component carrier and at least one secondary uplink component carrier;
- the random access procedure initiated by the UE according to the set random access policy is unsuccessful: the UE first initiates a random access procedure on the secondary uplink component carrier, and randomly initiates the at least one secondary uplink component carrier.
- the access process is unsuccessful, a random access procedure is initiated on the primary uplink component carrier, and when the random access procedure is initiated on the primary uplink component carrier, the random connection initiated on the set uplink component carrier is determined.
- the entry process was unsuccessful.
- the set uplink component carrier is a primary uplink component carrier
- the set uplink component carrier is a specific uplink component carrier
- the method further includes:
- the upper layer protocol layer such as the RRC layer, triggers the radio resource control connection re-establishment process. It is described in detail below.
- the timer is a newly defined timer when the downlink data arrives in a random access procedure triggered by a random access procedure event, and the random access procedure triggered by the event that the uplink data arrives requires a random access procedure
- the newly defined timer Tz is in the case of a random access procedure triggered by the UE to locate a random access procedure event.
- the timers Tx, Ty, Tz are initiated when the UE initiates a random access procedure on the first selected UL CC.
- the timers Tx, Ty, and Tz may also be the same timer. After the timer expires, the radio resource control connection re-establishment process is triggered.
- Step 20 The UE initiates a random access procedure in the selected UL CC.
- Step 40 The UE selects to initiate a random access procedure on other UL CCs. (A random access failure number on a UL CC cannot be selected again after reaching the maximum number of times)
- Step 60 The MAC layer indicates that there is a problem in the RRC layer random access.
- Step 70 The RRC layer considers the RLF to trigger the radio resource control connection re-establishment process. Or the RRC layer further determines whether the RLF triggers the radio resource control connection re-establishment process according to the operation condition of the foregoing related timer in this example.
- the MAC layer indicates an upper layer protocol layer such as an RRC layer random access problem; the specific UL CC may be a UL PCC or a UL that meets a preset condition. CC, the UE preferentially selects a specific UL CC to initiate a random access procedure.
- the specific uplink component carrier is an uplink component carrier with the best radio channel condition; or the uplink component carrier with the smallest path loss of the downlink component carrier associated therewith;
- the RRC layer receives the random access problem indicated by the MAC layer, and considers the RLF when the timer is not running, triggering the radio resource control connection reestablishment process.
- the timer is T301 and T31 1 in the case of the random access procedure triggered by the RRC connection reestablishment event; ⁇ 304 in the case of the random access procedure triggered by the handover event; the above timers ⁇ 301, ⁇ 31 1 , ⁇ 304
- the definition, start, and stop are identical to the prior art, which are defined in the relevant protocols, and the details are not described in the present invention.
- Step 10 The UE selects a random access resource and selects a UL CC.
- Step 30 Determine that the number of times the random access process is unsuccessful reaches the maximum number of times, if otherwise, execute step 20; if yes, go to step 40;
- Step 40 Whether the selected UL CC is a specific UL CC, if otherwise, step 50 is performed; If yes, go to step 60;
- Step 50 The UE selects to initiate a random access procedure on other UL CCs. (After the maximum number of random access failures on a UL CC reaches the maximum number of times, it cannot be selected again);
- Step 60 The MAC layer indicates that there is a problem in the RRC layer random access.
- Step 70 The RRC layer considers the RLF to trigger the radio resource control connection re-establishment process. Or the RRC layer considers the RLF when the timer is not running, triggering the radio resource control connection reestablishment process.
- the setting unit 40 is configured to set a random access policy for the UE
- the initiating unit 41 is configured to perform a random access procedure initiated by the set random access policy, and the determining unit 42 is configured to determine whether the random access procedure initiated by the initiating unit 41 is successful, and trigger the triggering unit when the method is unsuccessful;
