Description
Technical field
The present invention relates to field of wireless communication, relate in particular to a kind of service high-speed downlink shared transmission channel HS-DSCH cell switching method.
Background technology
From Release 5, third generation co-operative project (3rd Generation Partnership Project, (High Speed Downlink Packet Access, HSDPA) mechanism is in order to provide the downlink grouped high-speed transfer of interface aloft 3GPP) to provide the high speed downlink packet access.It is by high-speed downlink shared transmission channel (High Speed Downlink Shared Channel, HS-DSCH), high-speed downstream Physical Shared Channel (High Speed Physical Downlink Shared Channel, HS-PDSCH), downlink high-speed shared control channel (Shared Control Channel for HS-DSCH, HS-SCCH) and HS-DSCH dedicated uplink physical control channel (Dedicated Physical Control Channel (uplink) forHS-DSCH HS-DPCCH) interacts and to realize.Its mechanism is: by cell base station Node B conditions associated according to current downlink channel resource situation and user equipment (UE), implement dispatching algorithm, if decision scheduling shared channel resources is given certain UE, just transmitting scheduling information (comprising HS-DPSCH channel allocation, packet size, error protection mode etc.) is given this UE on the good HS-SCCH that belongs to this UE of configured in advance; Subsequently scheduling to the HS-PDSCH channel of this UE on according to the indication of schedule information transmission HS-DSCH data; After UE received schedule information, the form according to the schedule information indication on the specified HS-PDSCH channel of schedule information received the HS-DSCH data; Last UE feeds back to Node B with reception result and downlink wireless channel quality condition on HS-DPCCH; Node B is according to feedback information decision scheduling and transmission next time.
Realize in the channel of HSDPA, except HS-PDSCH information is to be carried in real time to the UE by the schedule information of HS-SCCH channel, other channel information all is by special Radio Resource control (Radio Resource Control, RRC) message is by radio network controller (Radio NetworkController, RNC) through Node B, interface transmission aloft and configuration are given UE's.And these channel informations can be in the process of operation be changed by RNC and the RRC reconfiguration message by correspondence is transferred to UE, reconfigure the channel information of renewal, thisly reshuffle when generally occurring in the sub-district and switching or resource reschedules the situation that waits other to reconfigure.
In the process that switch service HS-DSCH sub-district,, adopt the way of pre-configured HSDPA relevant information in the candidate cell of UE in order to accelerate handoff procedure.Have a plurality of candidate cells and all disposed HSDPA information, but have only the service HS-DSCH sub-district of this UE that HSDPA is provided transfer of data.The selection of candidate cell in the prior art, generally is the sub-district in the Active Set of UE.When UE carries out channel measurement to neighbor cell, satisfy the sub-district of measurement triggering condition 1A, if realize the soft handover of dedicated channel DCH, this sub-district will be added in the Active Set by RNC, and increases a wireless links (wherein disposing DCH) between this sub-district and this UE.For this sub-district is added the HSDPA candidate cell, the RRC message that RNC also reshuffles by radio bearer simultaneously disposes the HSDPA information of this sub-district for this UE, its flow process as shown in Figure 1:
Among Fig. 1, step 1 is the pre-configured flow process of HSDPA information to step 8, is described below:
Step 1, when UE measures neighbor cell (sub-district, target Node B place) for behind the candidate cell, send measurement report (measurement event is 1A) to Serving RNC (SRNC);
Step 2, SRNC decision are added this sub-district in the sub-district Active Set of this UE, by send Node B applying portion (Node B Application Part to target NodeB, NBAP) message: Radio Link is set up (Radio Link Setup) message, carry the dedicated channel configuration information, notice Node B is a UE configure dedicated channel;
The HSDPA candidate cell of this sub-district to this UE added in step 3-4, SRNC decision, by sending NBAP message: radio link reconfiguration (Radio Link ReconfigurationPrepare) message to target Node B, carry the HSDPA preconfigured information, notification target Node B is the pre-configured HSDPA of UE, but do not activate HSDPA, be the data transport service that target Node B does not provide HSDPA, the data transport service of HSDPA still is provided by source Node B;
Step 5-6, SRNC is by sending RRC message to UE: activating set updating (Active Set Update) message, carry dedicated channel configuration information (the dedicated channel configuration information that sends to Target cell with SRNC in the step 2 is identical), notice UE configure dedicated channel;
Step 7-8, SRNC are by sending RRC message to UE: radio bearer is reshuffled (Radio BearerReconfigurtion) message, carry HSDPA preconfigured information (the HSDPA preconfigured information that sends to Target cell with SRNC among the step 3-4 is identical), notice UE configuration HSDPA, but do not activate HSDPA;
Among Fig. 1, step 9 to step 13 for UE serves HS-DSCH sub-district switching flow, be described below:
Step 9, after UE measures the best cell information converting, send measurement report to RNC (measurement event is 1D);
The switching of HS-DSCH sub-district is served in step 10, SRNC decision, send NBAP message to target Node B: radio link reconfiguration is submitted (Radio Link Reconfiguration Commit) message to, and notification target Node B activates its HSDPA for this UE configuration;
Step 11-12, SRNC send RRC message to UE: radio bearer is reshuffled (Radio BearerReconfiguration) message, activates the HSDPA of the Target cell on the UE;
Step 13, SRNC send NBAP message to source Node B: radio link reconfiguration message (RadioLink Reconfiguration Prepare message or Radio Link Reconfiguration Request message), the HSDPA configuration information of this UE in the notification source Node B deletion cell-of-origin.
Because the order of deexcitation HSDPA is not set among the NBAP message Radio Link Reconfiguration, so need to delete the HSDPA configuration information of cell-of-origin after switching, like this, if user terminal switches go back to the cell-of-origin once more, because this sub-district also rests in the Active Set, do not have UE and report the 1A measurement report, SRNC need reconfigure this sub-district after receiving the 1D measurement report HSDPA gives this UE, this can strengthen handover delay, reduces systematic function.
In the pre-configured process of HSDPA, when the sub-district is chosen as dedicated channel Active Set sub-district, generally also can be chosen as the HSDPA candidate cell.Prior art need dispose the dedicated channel and the HSDPA of candidate cell by two NBAP message (Radio Link Setup and Radio Link Reconfiguration) respectively on target Node B; Also need two RRC message (Active Setup Update and Radio BearerReconfiguration) to give this UE configure dedicated channel and HSDPA respectively simultaneously.Because NBAP message RadioLink Setup and RRC message Active Setup Update can not be made as unactivated state with HSDPA, also needing NBAP message Radio Link Reconfiguration and RRC message Radio BearerReconfiguration that HSDPA is set is unactivated state.Therefore, multiple messages of the prior art has increased the transmission bandwidth load, causes the waste of channel resource, handles complexity between RNC and UE, RNC and the Node B and improves, and is configured to power and reduces, and the configuration time delay strengthens, thereby reduces systematic function.
In the HSDPA reconfiguration course, a RRC message (Radio Bearer Reconfiguration) once can only be reshuffled the HSDPA of a sub-district, in the time need reshuffling the HSDPA of a plurality of sub-districts simultaneously, need send many RRC message to UE, this has increased the load of wave point, reduce the probability of configuration successful, increase the processing complexity of UE and RNC.
In addition, if user terminal is served the switching of HS-DSCH sub-district simultaneously when SRNC sends Active Set Update message, prior art will be in above-mentioned process step 5, in Active Set Update message, add the information of new Serving cell, but this message is not cancelled the information of old service HS-DSCH sub-district, will cause the processing behavior of UE to expect.
