Embodiment
The key of technical solution of the present invention is, insert (High SpeedDownlink Packet Access from the existing high speed downlink packet of UE, HSDPA) reserve in the needed buffer memory of process, the existing HSDPA of restriction can only use original part of cache, utilize the vacant buffer memory that comes out to support HS-SCCH Less operation, reach the purpose that need not additionally increase the UE buffer memory.
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is further elaborated below in conjunction with accompanying drawing.
A RNC configuration UE increases HS-SCCH Less operation by the following examples, and the situation of for this reason reserving buffer memory describes.The message of enumerating in this explanation is not limited in provide among the embodiment several.
Embodiment one
The cache size notice NodeB that RNC is at first required with HS-SCCH Less operation, NodeB carries out corresponding buffer memory reservation operations, and with buffer memory assignment information notice RNC.Notify UE by RNC or NodeB with the buffer memory assignment information then, UE operates required buffer memory according to described relevant parameter with the HS-SCCH Less that reserves and distributes to HS-SCCH Less operation, and the HSDPA process is restricted to the buffer memory that uses outside the described reservation buffer memory.Figure 1 shows that the realization flow of embodiment one scheme, comprise the steps:
Step 101:RNC carries the configuration information that HS-SCCH Less operates required buffer memory by the Iur/Iub interface in the message that NodeB sends, described message such as Radio Link are set up message or radio link reconfiguration message.
The configuration information that the HS-SCCH Less that carries in the described radio link reconfiguration message operates required buffer memory is divided into following situation:
The buffer memory demand C that situation 1, configuration information are operated for HS-SCCH Less
Less
Configuration information is the buffer memory demand C of HS-SCCH Less operation
LessNodeB is after receiving this configuration information, with C
LessAnd convert between the needed buffer memory of existing HSDPA process, as to establish the largest buffered that UE can support be C, maximum process number is N, and then each process buffer memory that can use is C/N, and promptly the HS-SCCH Less buffer memory demand of operating is equivalent to have now HSDPA's
The buffer memory demand of individual process.
Situation 2, configuration information are equivalent to the process number of existing HSDPA for HS-SCCH Less operation buffer memory demand.
RNC is according to the method in the situation 1, with the buffer memory demand C of HS-SCCH Less operation
LessAnd convert between the needed buffer memory of existing HSDPA process, the buffer memory that need reserve for HS-SCCH Less operation is that parameter L is carried in the message as described configuration information, described message such as radio link reconfiguration.
The mode of situation 3, predefined reservation buffer memory.
It is C that the pre-defined support of RNC and NodeB HS-SCCH Less operates needed cache size
Less, RNC informs that by increase indication information in message NodeB need reserve buffer memory, the indication field of described configuration information such as 1bit for HS-SCCH Less; NodeB learns that according to definition in advance HS-SCCH Less operates needed buffer memory.
After step 102:NodeB receives described message, carry out the reservation operations that HS-SCCH Less operates required buffer memory, and return response message to RNC.Carry in the described feedback message and be used to represent that HS-SCCHLess operates the buffer memory assignment information of required buffer memory.Described response message can be a Radio Link foundation/reconfiguration response message.
The reservation operations that described HS-SCCH Less operates required buffer memory comprises:
NodeB judges that UE is current does not have occupied buffer memory whether more than or equal to the buffer memory demand of the HS-SCCH Less operation of indicating in the configuration information of being received, if NodeB reserves HS-SCCH Less and operates available cache size C in not having occupied buffer memory
Less' (〉=C
Less), NodeB sends response message to RNC, otherwise NodeB discharges the demand that some processes satisfy L process cache of HS-SCCH Less action need according to certain rule, reserves the available cache size C of HS-SCCH Less operation again in not having occupied buffer memory
Less' (〉=C
Less), and to RNC transmission response message.
The release process rule that described NodeB adopts can for following any:
1), in occupied process, selects randomly; Perhaps
2), according to the prioritization of the data of being stored in the occupied process, begin to discharge from the minimum process of priority; Perhaps
3), according to the occupied time-sequencing that continues of process, begin to discharge from the longest process of holding time; Perhaps
4), when UE has disposed many input and output (MIMO) pattern, NodeB discharges occupied process in pairs, also is that these processes are matched use when the MIMO stream transmission.Illustrate, process identification (PID) is respectively HAP_ID and (HAP_ID+N in existing mode
Proc/ 2) mod (N
Proc) process when stream transmission, match use, N
ProcBe the process sum of high-rise configuration, N
Proc=16 o'clock processes as sign=0 and sign=8, NodeB has discharged the process of process identification (PID) sign=0 in this mode, also needs to discharge simultaneously the process of process identification (PID) sign=8.
Described buffer memory assignment information comprises the combination in any of following parameter: the cache size C that HS-SCCH Less operation is available
Less' (〉=C
Less), the cache size C-C that the existing HSDPA of UE can use
Less', the process number that the existing HSDPA of UE can use, as N or (N-L) individual, each has disposed the cache size of HSDPA process, and the buffer memory demand of HS-SCCH Less operation is equivalent to the process number L of existing HSDPA.If NodeB has discharged at least one process, then the buffer memory assignment information also needs to comprise the process identification (PID) that is discharged.
Also can default buffer memory assignment information in the response message or only comprise the indication field of 1bit, the expression acquiescence NodeB required cache size C that successfully has been HS-SCCH Less operative configuration
Less, also promptly to give tacit consent to the existing HSDPA of UE and use N-L process, cache size is C-C
Less, N-L process divided equally these buffer memorys.
At the different situations of step 101, NodeB is known the buffer memory demand C of HS-SCCH Less operation
Less, below the buffer memory assignment information is specifically described:
Situation 1: if be buffered between each process is mean allocation, and NodeB is according to C
LessCan convert out the process of the required HSDPA of HS-SCCH Less operation and count L, the cache size C-C that HSDPA can be used
LessAnd/or the required cache size of the process number (N-L) that can use of parameter L and/or HSDPA and/or each process is as buffer memory assignment information notice RNC.
Situation 2: if be buffered between each process is not mean allocation, and NodeB can't count L for process with the buffer memory demand conversion of HS-SCCHLess operation, and then NodeB directly reserves HS-SCCH Less operation available cache memory size C in unappropriated buffer memory
Less' (〉=C
Less), and with the available cache size C of HS-SCCH Less operation
Less' (〉=C
Less) and/or the existing HSDPA of the UE cache size C-C that can use
Less' and/or the required cache size of the process number that can use of HSDPA and/or each process as buffer memory assignment information notice RNC.
Situation 3: except the situation of above-mentioned buffer memory assignment information, if buffer memory demand C
LessGreater than the vacant buffer memory of UE, then NodeB discharges at least one process according to aforementioned rule, and the buffer memory assignment information further comprises the process identification (PID) that is discharged.
Step 103:RNC sends Radio Resource control (RRC) message by the Uu interface to UE, carries the buffer memory assignment information in this RRC message.
Need to guarantee that in advance HSDPA, HS-SCCH Less are operated employed cache size for NodeB and UE or the process number is a cognitive consonance.Message is set up in described RRC message such as RRC connection, radio bearer (Radio bearer) is set up message, RB reconfiguration message or transmission channel reconfiguration message etc.
In addition, NodeB can also utilize the mode of physical layer control channel with buffer memory assignment information UE on the Uu interface, as the buffer memory assignment information being included in the new control channel form, described control channel such as HS-SCCH or enhancing dedicated channel (Enhanced Dedicated Channel, E-DCH) absolute grant channel (E-DCH Absolute Grant Channel, E-AGCH).
Step 104:UE carries out cached configuration according to the buffer memory assignment information of being received, is about to keep for the buffer memory of HS-SCCH Less operation to distribute to HS-SCCH Less operation, the HSDPA process is restricted to the buffer memory that uses outside the described reservation buffer memory; And to RNC transmission RRC response message.
According to the difference of buffer memory assignment information, below the buffer memory of keeping for HS-SCCH Less operation distributed to HS-SCCH Less operation describe:
1) the buffer memory assignment information is parameter L and/or parameter (N-L):
The buffer memory of keeping for HS-SCCH Less to operate is distributed to HS-SCCH Less and is operating as: the buffer memory of L process is distributed to HS-SCCH Less operation;
2), the buffer memory assignment information is the available cache size C of HS-SCCH Less operation
Less' (〉=C
Less) and/or the existing HSDPA of the UE cache size C-C that can use
Less':
The buffer memory of keeping for HS-SCCH Less to operate is distributed to HS-SCCH Less and is operating as: with size is C
Less' buffer memory distribute to HS-SCCH Less operation.
3) default buffer memory assignment information;
The buffer memory of keeping for HS-SCCH Less to operate is distributed to HS-SCCH Less and is operating as: the free buffer of pre-sizing is distributed to HS-SCCH Less operation.
Need to discharge the process identification (PID) of buffer memory or supply the employed process identification (PID) of HSDPA if also carry in the RRC message that UE receives; Before carrying out cached configuration, described UE to comprise the steps: also that then UE discharges the process of the process identification (PID) correspondence that needs the release buffer memory.
After UE finishes the configuration that HS-SCCH Less operates used buffer memory, if stop the related business of HS-SCCHLess operation, VoIP business for example, then RNC configuration UE deletion HS-SCCH Less operation, and discharge HS-SCCH Less and operate shared buffer memory.The situation of operating shared buffer memory below by two pairs of RNC configuration UE release of embodiment HS-SCCH Less describes.

1) which process the buffer memory of Shi Fanging distributes to, the ID of these processes, and/or
2) these processes cache size of being distributed separately, as divide equally the buffer memory of release, or distribute separately for each process.
When adopting the mode of synchronous reprovision, NodeB promptly before synchronized radio link reconfiguration procedure comes into force, preferentially used the shared buffer memory of non-HS-SCCH Less operation before activationary time point.
Step 203:RNC sends to carry to UE by the Uu interface and discharges the RRC message that HS-SCCH Less operates the indication information of shared buffer memory.
Scheme possible on the Uu interface is listed below, and (Radio bearer RB) discharges, RB reshuffles, transmission channel reconfiguration message etc., the indication of described indication information such as 1bit for described RRC message such as radio bearer.It is several that described message is not limited only to list above.
RNC increases indication information in described RRC message, notice UE discharges the shared buffer memory of HS-SCCH Less operation, the indication of described indication information such as 1bit.
RNC can also be with the reconfiguration information notice UE of d/d buffer memory in RRC message, and described reconfiguration information is as follows:
1) which process the buffer memory of Shi Fanging distributes to, the sign of these processes, and/or
2) these processes cache size of being distributed separately, as divide equally the buffer memory of release, or distribute separately for each process.
In addition, NodeB can also utilize the mode of physical layer control channel on the Uu interface, with discharging the indication information notice UE that HS-SCCH Less operates shared buffer memory, as indication information being included in the new control channel form described control channel such as HS-SCCH or E-AGCH.
Step 204:UE finishes described releasing operation by indication information after receiving described RRC message, and returns the RRC response message to RNC.
In addition, RNC makes the MAC-hs entity of NodeB and UE reset (Reset) earlier by the signaling of Iur/Iub, Uu interface respectively, and then carries out the configuration or the release of HS-SCCH Less operation buffer memory according to embodiment one and embodiment two.
