Description

Be used to improve the method and the subscriber equipment of SNPL report mechanism

Technical field

Present invention relates in general to TD SDMA (TD-SCDMA) system, and relate more particularly to the service of subscriber equipment (UE) in the uplink service that High Speed Uplink Packet in the TD-SCDMA system inserts (HSUPA) service/enhanced high-speed grouping access (HSPA+) and the improvement of adjacent sub-district path loss (SNPL) report mechanism.

Background technology

In general, the high-throughput uplink service of high-throughput HSUPA service/HSPA+ will make UE generate high rise-over-thermal (RoT) in the Serving cell of this UE and adjacent sub-district in cellular communication system.When this UE was positioned at the edge of Serving cell, this problem became even worse for adjacent sub-district.

Wideband Code Division Multiple Access (WCDMA) (WCDMA) system introduces the physical channel that is called as E-DCH relative authorization channel (E-RGCH) and solves the problems referred to above.Especially, adjacent sub-district can use E-RGCH to reduce the through-put power of UE to reduce the RoT in the adjacent sub-district.

Yet, owing in the TD-SCDMA system, do not have soft handover, so there is not E-RGCH.Current, employing SNPL report mechanism is handled the problems referred to above at the TD-SCDMA system.Specifically, UE periodically reports at the Serving cell of this UE and the SNPL of adjacent sub-district to Serving cell.Serving cell uses about the information of SNPL and controls RoT in the adjacent sub-district.For example, if the approaching adjacent sub-district of UE, then serving BS (BS) will give the less power mandate to UE based on the SNPL that is reported.As a result, UE will can not cause high RoT in adjacent sub-district.In general, the RoT of adjacent sub-district control depends on the frequency and the accuracy of SNPL report mechanism widely.

At present, aforesaid SNPL report mechanism is at UE always and works under the situation in the sub-district well.Yet when UE switches to another sub-district, the SNPL report mechanism will suffer serious problem.Describe this problem below in detail.

In the uplink service of the HSUPA of TD-SCDMA system service/HSPA+, the process relevant with the switching of UE can be divided into following four-stage.

Stage 1.

UE provides the serving BS broadcasts of service to send measurement report to the radio network controller that is coupled to this UE (RNC) via the Serving cell for UE.Need the switching of UE from the Serving cell to the Target cell if RNC judges based on measurement report, then RNC sends radio link reconfiguration to the target BS that service is provided for Target cell and prepares message, and sends radio bearer reconfiguration message to UE.In case receive radio bearer reconfiguration message, then UE prepares for switching.

In this stage, UE can carry out the ul transmissions at the uplink service of HSUPA service/HSPA+.And UE can report measured SNPL to the SNPL of Serving cell and adjacent sub-district and to serving BS broadcasts by surveyingpin.

Stage 2.

In case UE is ready to switch, it is just carried out and switches.Switch complete after, UE sends radio bearer to RNC and reshuffles and finish message.

In this stage, UE can not carry out can not measuring and report SNPL at the ul transmissions of the uplink service of HSUPA service/HSPA+.

Stage 3.

RNC sends the radio resource control layer 3(RRC L3 of the adjacent cell list that comprises Target cell to UE) the measurement control messages.In case receive this adjacent cell list, UE just begins the SNPL of surveyingpin to all sub-districts in this adjacent cell list.

In this stage, UE can carry out the ul transmissions at the uplink service of HSUPA service/HSPA+.But UE is energy measurement and report SNPL not.

Stage 4.

In case measured new effective SNPL, UE is just to the measured SNPL of target BS report.In other words, UE can normal running in Target cell now.

In this stage, UE can carry out the ul transmissions at the uplink service of HSUPA service/HSPA+, and measures and report SNPL.

With reference to figure 1, be shown schematically in the traffic carrying capacity of UE in the stage 1 to 4.Traffic carrying capacity in the stage 1 is low, because UE is positioned at the edge of Serving cell in this stage.So in the stage 2, equal zero because carried out the switching traffic carrying capacity.So in the stage 3 owing to there is not SNPL report traffic carrying capacity very low.Traffic carrying capacity is high in the stage 4, because target BS can receive SNPL in this stage.

Notice that in the stage 3, UE must wait for the adjacent cell list of the Target cell that the UE from RNC has switched to, because UE needed to know adjacent tabulation before measuring SNPL.In other words, receive adjacent tabulation up to UE, it just can begin SNPL and measure.In addition, in order to keep network stabilization.Target BS will can not give UE too many power mandate before measuring new effective SNPL.

Therefore, the stage 3 can continue nearly 250ms, and this throughput to the UE of the uplink service of HSUPA service/HSPA+ has very large negative effect, as shown in FIG. 1.

Therefore, expectation is provided a kind of shorten or even the omission stage 3 so that produce the technical scheme of as far as possible little negative effect.

At first summarize principle of the present invention.

For the process that comprises the foregoing stage 1 to 4, basic conception of the present invention is that in the stage 1, in case the RNC judgement needs the switching of UE from the Serving cell to the Target cell, this RNC just sends the adjacent cell list of Target cell to UE.By this way, UE will know the adjacent cell list of Target cell in the stage 1, rather than as in the stage 3, knowing the adjacent cell list of Target cell described in this process.

The adjacent cell list of early knowing Target cell can be so that shorten or the omission stage 3.Specifically, because UE knows the adjacent cell list of Target cell in the stage 1, so this UE does not need to wait in the stage 3 adjacent cell list from the Target cell of RNC.This will shorten the stage 3.Preferably, in the stage 1, in case receive the adjacent cell list of Target cell, UE just can begin the SNPL of surveyingpin to all sub-districts in the adjacent cell list of Target cell.By this way, when finishing switching, UE can report measured SNPL to target BS in the stage 4, thereby makes the stage 3 become unnecessary.

Pass through the example embodiment of the present invention will be described in more detail below with reference to Fig. 2 to Fig. 4.

Fig. 2 is the schematic block diagram of a part 200 of wherein implementing the TD-SCDMA system of various embodiment of the present invention.This part 200 comprises RNC 202, serving BS broadcasts 204, target BS 206 and the UE 208 that comprises one or more treatment circuits 210.Before the switching of UE 208, RNC 202 is coupled to UE 208 via the serving BS broadcasts 204 that service is provided for Serving cell.If UE 208 is accomplished to the successful switch of Target cell, then RNC 202 will be coupled to UE 208 via the target BS 206 that service is provided for Target cell.Described one or more treatment circuit 210 be configured at UE 208 from the Serving cell to the Target cell switching and improve the SNPL report mechanism of UE 208 in the uplink service of the HSUPA service/HSPA+ in the TD-SCDMA system.Should be appreciated that described one or more treatment circuits 210 can comprise hardware, firmware, software or its any combination.

With reference to figure 3, illustrate in the uplink service of the explanation HSUPA service/HSPA+ in the TD-SCDMA system according to an illustrative embodiment of the invention at UE 208 from the Serving cell to the Target cell switching and improve the flow chart of method 300 of the SNPL report mechanism of this UE 208.Method 300 is carried out by the one or more treatment circuits among the UE 208 210.

This method 300 in step 302, needs described switching if RNC 202 judges with step 302 beginning, and then UE 208 tabulates from RNC 202 receiving target adjacent cells of cells.For example, the adjacent cell list of Target cell can be contained in the RRC L3 measurement control messages that is sent by RNC 202.

In step 304, except the SNPL at all sub-districts in the adjacent cell list of Serving cell, UE 208 goes back the SNPL of surveyingpin to all sub-districts in the adjacent cell list of Target cell then.Just, on the one hand, as in the prior art, UE 208 surveyingpins are to the SNPL of all sub-districts in the adjacent cell list of Serving cell.On the other hand, UE 208 while surveyingpin is to the SNPL of all sub-districts in the adjacent cell list of Target cell.In one embodiment, the measurement in the step 304 is periodically carried out.For example, the every 5ms of the measurement in the step 304,10ms or 20ms are performed once.

Similar with the process that comprises the foregoing stage 1 to 4, the measurement in the step 304 is performed, and finishes up to stage 1, and carries out in the stage 2 of switching measurement in the execution in step 304 not at UE 208.

In step 306, UE 208 reports that based on the result of switching measured SNPL uses for the uplink service of HSUPA service/HSPA+ at last.In one embodiment, if handover success, then UE 208 reports the SNPL that records at all sub-districts in the adjacent cell list of Target cell to target BS 206.As a result, the stage 3 in the foregoing process can be omitted basically, and this will produce greatly the throughput of the UE 208 of the uplink service that is used for HSUPA service/HSPA+ and improve.

In addition, if handoff failure, then UE 208 reports the SNPL that records at all sub-districts in the adjacent cell list of Serving cell to serving BS broadcasts 204, and this makes 300 pairs of existing SNPL report mechanisms of method have slight influence.

Fig. 4 illustrate in the uplink service of the HSUPA service/HSPA+ in the TD-SCDMA system of explanation another exemplary embodiment according to the present invention at UE 208 from the Serving cell to the Target cell switching and improve the flow chart of method 400 of the SNPL report mechanism of UE 208.Method 400 is carried out by the one or more treatment circuits among the UE 208 210.

Method 400 is with step 402 beginning, and is similar with step 302, in step 402, needs described switching if RNC 202 judges, then UE 208 tabulates from RNC 202 receiving target adjacent cells of cells.For example, the adjacent cell list of Target cell can be contained in the RRC L3 measurement control messages that is sent by RNC 202.

In step 404, UE 208 surveyingpins are to the SNPL of all sub-districts in the adjacent cell list of Serving cell then.Although UE 208 has received the adjacent cell list of Target cell, in this step it not surveyingpin to the SNPL of all sub-districts in the adjacent cell list of Target cell.Replace, UE 208 as prior art only surveyingpin to the SNPL of all sub-districts in the adjacent cell list of Serving cell.In one embodiment, the measurement in the step 404 is periodically carried out.For example, the every 5ms of the measurement in the step 404,10ms or 20ms are performed once.

Similar with the process that comprises the foregoing stage 1 to 4, the measurement in the step 404 is performed, and finishes up to stage 1, and carries out in the stage 2 of switching measurement in the execution in step 404 not at UE 208.

In step 406, UE 208 reports that based on the result of switching measured SNPL uses for the uplink service of HSUPA service/HSPA+ at last.In one embodiment, if handover success, then UE 208 surveyingpins are to the SNPL of all sub-districts in the adjacent cell list of Target cell, and the SNPL that records at all sub-districts in the adjacent cell list of Target cell to target BS 206 reports.As a result, the stage 3 in the foregoing process can be shortened widely, and this will produce significant the improvement to the throughput of the UE 208 of the uplink service that is used for HSUPA service/HSPA+.

In addition, if handoff failure, then UE 208 reports the SNPL that records at all sub-districts in the adjacent cell list of Serving cell to serving BS broadcasts 204, and this makes 400 pairs of existing SNPL report mechanisms of method have slight influence.

In a word, the application of the invention has improved the performance of the uplink service of the HSUPA service/HSPA+ in the TD-SCDMA system at the switching of UE on the one hand widely.On the other hand, introducing of the present invention has slight influence to the current techniques standard in the TD-SCDMA system.
