Description
Technical field
The present invention relates to 3G (3G (Third Generation) Moblie technology) field, relate in particular to the scheduler among maintenance method, UE and the Node B (base station) of UE (subscriber equipment) connection status in HSUPA (high speed uplink packet access) communication system.
Background technology
In the HSUPA communication system, transfer of data is divided into scheduled transmission and two kinds of patterns of non-scheduled transmission, introduces respectively below.
Scheduled transmission
The main benefit of Node B fast dispatch is can reduce propagation delay time and improve throughput when carrying out continuous data when transmission, this be because reduced on the Iub interface transmission course and to the quick feedback that retransmits, the UE buffer memory is measured.The main body of operation dispatching transmission is a scheduler among the Node B.
Referring to Fig. 1, be the scheduled transmission schematic diagram.The HSUPA scheduling process may further comprise the steps:
1, UE initiates dispatch request by E-RUCCH (enhanced uplink random access channel);
Dispatch request comprises the sign of scheduling relevant information and UE.
2, after Node B received the UE dispatch request, if allow this UE to send uplink strengthening data, NodeB sent by E-AGCH (strengthening the absolute grant channel of dedicated transmission channel) and inserts permission information to UE;
Insert and allow information spinner will comprise that power allows and physical resource allows.E-AGCH is descending physical channel, has carried configuration informations such as the resource of Node B and power, comprises TPC (transmitting power control) and SS (simultaneous bias) order to E-PUCH (enhancing uplink physical channel).
3, after UE receives the access permission information that E-AGCH carries,, on E-PUCH, send uplink strengthening data to Node B according to inserting resource and the power that allows information distribution;
4, after Node B receives data and carries out demodulating and decoding, feeding back ACK/nack message on the E-HICH that this UE monitors, UE judges whether that according to feedback information needs retransmit.
UE can order the connection status of keeping self according to the TPC/SS that Node B in the step 2 issues, and also promptly adjusts transmitting power, and keeps synchronously.
Two, non-scheduled transmission
Non-scheduling mainly is to use under light at cell load, that the uplink UE data volume the is little situation, and this mode helps low data bulk and to the business of delay sensitive.
In the non-scheduled transmission, system is that UE has reserved the certain physical resource, and by high-level signaling notice UE, no longer sends dispatch request and receive E-AGCH before the each transmission of UE, but on reserved resource, directly send uplink strengthening data, and on E-HICH receiving feedback information.E-HICH also carries different code words except loading ACK/NACK, UE converts to these code words after receiving feedback information, obtains the TPC/SS order of Node B indication, thereby adjusts transmitting power, and keep synchronously.
No matter adopt which kind of pattern, all need the connection status of UE is kept, as above-described, the maintenance of UE connection status mainly comprises two aspects, the one, adjust transmitting power, the 2nd, keep synchronously.
If UE has continuous upstream or downstream data always, then can keep oneself state by the TPC/SS that reception Node B issues, yet, when using HSUPA professional, be not to have data to transmit all the time, probably in the of short duration time period, there are not data, still, the problem that the UE state kept when existing above-mentioned two kinds of patterns did not all have to consider not have transfer of data.
For above-mentioned two kinds of transmission modes, if temporarily there is not transfer of data, UE and Node B will end alternately, after a period of time, the just possible step-out of UE is when having new transfer of data again, just the process that need insert has at random again increased signaling consumption and time delay.And the step-out of UE can produce all the other UE and disturb, and makes the whole communication system decreased performance, should avoid as far as possible.
Summary of the invention
In view of this, the invention provides a kind of method,, keep the connection status of UE in order to when not having transfer of data; Simultaneously, the present invention also provides a kind of UE and scheduler.
For this reason, the present invention adopts following technical scheme:
A kind of maintenance method of UE connection status comprises step: start UE and regularly send predefined message to Node B; After receiving described predefined message, Node B feeds back the order of keeping connection status to UE at every turn, and UE utilizes described order to keep self connection status.
Wherein, starting UE regularly to the condition of Node B transmission predefined message is: UE receives the notice that enters discontinuous mechanism that NodeB sends.
Enter discontinuous mechanism notice but when not receiving predefined message sending, Node B continues to send and enters notice, up to receive predefined message or send the notice number of times surpass preset enter the number of times threshold value.
Said method also comprises: when receiving Node B when withdrawing from discontinuous mechanism notice or entering other mechanism notices, perhaps, the number of times that sends predefined message to Node B as UE stops to send predefined message to Node B during more than or equal to the threshold value that presets.
Withdraw from discontinuous mechanism notice but still when receiving predefined message, Node B continues to send OPT-OUT NOTICE sending, up to receive finish response message or send the OPT-OUT NOTICE number of times surpass preset withdraw from the number of times threshold value.
Perhaps, starting UE regularly to the condition of Node B transmission predefined message is: the time that does not have business datum to transmit surpasses the threshold value that presets.
Said method also comprises: when new business datum need be transmitted, stop to send predefined message to Node B.
Said method also comprises: after described subscriber equipment entered discontinuous mechanism, subscriber equipment was according to the data on the discrete reception of the discontinuous receiving cycle E-AGCH.
A kind of UE comprises the mutual interface unit with Node B, and utilizes the maintenance that Node B sends to connect the maintenance unit that status command carries out state-maintenance, also comprises: message unit, be used to generate with the NodeB reservation in order to represent the message of discontinuous mechanism; Scheduling unit is used to control described interface unit and regularly sends described message to Node B.
Above-mentioned interface unit is further used for receiving the discontinuous mechanism notice that enters that Node B sends; Described scheduling unit after described interface unit receives described notice, just starts described interface unit and sends described message.
Above-mentioned UE also comprises receiving element, is used for after entering discontinuous mechanism, according to the data on the discrete reception of the discontinuous receiving cycle E-AGCH.
Above-mentioned UE also comprises and is used for the statistic unit that the time that does not have transfer of data is added up, the threshold cell of preserving time threshold, and the comparing unit of responsible comparative statistics time value and described threshold value; Described scheduling unit when described comparing unit is determined the timing statistics value more than or equal to described threshold value, just starts described interface unit and sends described message.

Embodiment
The present invention adopts following technical scheme: when not having the regular traffic transfer of data, UE sends predefined message to Node B, after Node B receives this message, will send the order that is used to safeguard the UE connection status that constitutes by TPC and SS etc. to UE, at this moment, UE can adjust self parameter according to the order that receives, to keep the connection status of self and Node B.Thus, when the short time did not have business data transmission, UE also can keep self connection status, and can will not rebulid random access procedure owing to step-out, has reduced signaling consumption and time delay.
, such scheme is defined as " discontinuous mechanism " herein, as seen, UE sends the beginning that predefined message indicates discontinuous mechanism to Node B, and UE stops to send the end that predefined message indicates discontinuous mechanism to Node B.
Wherein, start the condition of discontinuous mechanism (UE sends predefined message to Node B), can have multiple.In scheduled transmission mode, for example, can initiatively enter discontinuous mechanism notice by Node B and start to the UE transmission.In non-scheduled transmission mode, then can rely on UE self to judge the discontinuous mechanism that when enters that decides, for example, when the time that does not have business data transmission surpasses certain threshold value, promptly begin to send predefined message to Node B, certainly, in scheduled transmission mode, also can adopt this mode in the non-scheduled transmission mode by UE self decision.
Correspondingly, when satisfying some condition, can withdraw from discontinuous mechanism (UE stops to send predefined message to Node B), exit criteria also has multiple.Obviously, when UE had business datum to transmit with Node B, nature will withdraw from discontinuous mechanism.In addition, in scheduled transmission mode,, also should withdraw from when Node B initiatively sends when withdrawing from discontinuous mechanism notice or entering continuous mechanism (regular traffic transmission mechanism) notice to UE.Have again, can also withdraw from by the number of times that limits UE transmission predefined message, also be, when UE when Node B sends the predefined message number of times and surpasses the preset gate limit value, withdraw from discontinuous mechanism, show have considerable time not have business datum this moment, so, just no longer keep the UE connection status by discontinuous mechanism.
Below in conjunction with accompanying drawing, the embodiment of the invention is described in detail.
At first introduce the embodiment one of discontinuous mechanism in the scheduled transmission mode.
Also see also Fig. 1, in the existing scheduled transmission mode, when not having transfer of data between UE and the Node B, just there is not configuration information to issue on the E-AGCH, E-PUCH does not have uplink strengthening data to need to send, and E-HICH does not have ACK/NACK message to need feedback yet.And in the present embodiment, in order to keep power control with synchronously, UE sends certain data in up still the needs, so that Node B can judge whether the transmitting power of UE and transmitting time be suitable by these data, and generates corresponding TPC/SS order and notifies UE to adjust.Different with E-HICH loading ACK/NACK in the existing scheduled transmission mode, the E-HICH in the present embodiment carries the TPC/SS order in discontinuous mechanism.
In the present embodiment, the startup of discontinuous mechanism and the mode that withdraws from employing Node B notice UE also are that Node B scheduling UE begins to send predefined message or stops to send predefined message.
Node B informs that by specific information prior and the UE agreement UE enters or withdraw from discontinuous mechanism on E-AGCH.So-called specific information is meant the field that does not adopt in the normal transmission.For example, definition when E-AGCH indicate the number of ENI equal 8 and UE designated during the solid size road of SF16, UE enters discontinuous mechanism, this E-AGCH is called as " discontinuous beginning E-AGCH ", those skilled in the art understand, there are 8 to take 34 * 8=272bit altogether when the ENI number equals 8 expression E-UCCH, on the code channel of a SF16, can't carry like this, therefore belong to special information.Similarly, when the number of E-AGCH indication ENI equal 7 and UE designated during the solid size road of SF16, UE leaves discontinuous mechanism, this E-AGCH is called as " discontinuous end E-AGCH ".When UE receives discontinuous beginning or finishes E-AGCH, also promptly be equivalent to receive the notice that enters or withdraw from discontinuous mechanism.
When UE receives the E-AGCH of comprising of Node B of special information, promptly enter discontinuous mechanism, just begin regularly to send predefined message to Node B.The form of predefined message can be provided with flexibly, for example, all adopts the information of bit 1 or adopts cache information SI; The time interval that sends predefined message also can be provided with flexibly, for example sends on corresponding physical resource every k subframe.Wherein, the form of predefined message and transmission also are to make an appointment between UE and the Node B at interval.
Node B after receiving the predefined message of UE, promptly on E-HICH to UE feedback TPC/SS order, correspondingly, UE orders according to TPC/SS, keeps the connection status of self and Node B.
As preceding surface analysis, have multiple situation can cause UE to withdraw from discontinuous mechanism: 1. Node B sends the E-AGCH that comprises OPT-OUT NOTICE to UE, this moment, UE stopped to send predefined message to Node B, in addition, UE can also obtain the response message of end notification to Node B feedback, for example, send specific bit 0 expression and known the discontinuous mechanism that withdraws from.2. UE receives and enters other mechanism notices, when for example receiving other E-AGCH or HS-SCCH (descending shared control signal channel) information, can withdraw from discontinuous mechanism immediately.3. UE has new business datum to need to send, and at this moment, UE can directly send initiatively OPT-OUT NOTICE to Node B, for example sends specific bit 0, informs that Node B will withdraw from discontinuous mechanism, behind the ACK that obtains Node B feedback, just withdraws from discontinuous mechanism.
Referring to Fig. 2, the flow chart for embodiment one comprises:
Step 201:Node B determines to enter discontinuous mechanism;
Step 202:Node B sends discontinuous beginning E-AGCH to UE;
Step 203:UE sends predefined message on the physical resource of E-AGCH indication, and according to reservation at interval, regularly sends;
Step 204:UE regularly receives the TPC/SS order on E-HICH, and according to TPC/SS order indication, adjusts transmitting power and keeps synchronously, to keep the connection status with Node B;
Does step 205:UE receive discontinuous end E-AGCH? if, execution in step 206, otherwise, execution in step 207;
Step 206:UE sends specific end response message on E-PUCH, withdraw from then;
Does step 207:UE receive other E-AGCH or HS-SCCH information? if, directly withdraw from, otherwise, execution in step 208;

Step 209:UE sends initiatively OPT-OUT NOTICE on E-PUCH;
Whether step 210:UE receives the affirmation feeding back ACK that initiatively withdraws from E-HICH, if, withdraw from, otherwise, execution in step 209 returned.
Above-mentioned shown in Figure 2 be the flow process of discontinuous mechanism under the normal condition, in actual applications, might have some abnormal conditions.For example, Node B sends discontinuous beginning E-AGCH to UE, but UE does not receive, so, UE just can not send predefined message to Node B, at this moment, Node B can send discontinuous beginning E-AGCH again, if can not get the feedback of UE always, Node B can send always; Continue to take place for fear of the problems referred to above, can set the number of times threshold value that Node B sends discontinuous beginning E-AGCH, when sending number of times, just no longer send more than or equal to this threshold value.In like manner, if Node B has sent discontinuous end E-AGCH, but UE does not receive, UE just can not send response message on corresponding physical resource so, and at this moment, Node B can continue to send discontinuous end E-AGCH, if can not get the feedback of UE always, Node B also can send always; Continue to take place for fear of the problems referred to above, can set Node B and send the number of times threshold value that discontinuous mechanism finishes E-AGCH, when sending number of times, just no longer send more than or equal to this threshold value.
Introduce the embodiment two of discontinuous mechanism in the scheduled transmission mode below.
On the basis of embodiment one, present embodiment has increased a kind of mode that withdraws from discontinuous mechanism.Also promptly, the number of times threshold value L that UE sends predefined message is set, when UE sends number of times above threshold value, then withdraws from discontinuous transmission mechanism.

Step 301:Node B determines to enter discontinuous mechanism;
Step 302:Node B sends discontinuous beginning E-AGCH to UE;
Step 303:UE sends predefined message on the physical resource of E-AGCH indication, and according to reservation at interval, regularly sends;
Step 304:UE regularly receives the TPC/SS order on E-HICH, and according to TPC/SS order indication, adjusts transmitting power and keeps synchronously, to keep the connection status with Node B;
Does step 305:UE send the number of times of predefined message more than or equal to L? if, withdraw from, otherwise, execution in step 306;
Does step 306:UE receive discontinuous end E-AGCH? if, execution in step 307, otherwise, execution in step 308;
Step 307:UE sends specific response message on E-PUCH, withdraw from then;
Does step 308:UE receive other E-AGCH or HS-SCCH information? if, directly withdraw from, otherwise, execution in step 309;
Whether step 309:UE has new business datum to need to send, if, execution in step 310, otherwise, repeated execution of steps 303 returned;
Step 310:UE sends initiatively OPT-OUT NOTICE on E-PUCH;
Whether step 311:UE receives the affirmation feeding back ACK that initiatively withdraws from E-HICH, if, withdraw from, otherwise, execution in step 310 returned.
Treatment mechanism to abnormal conditions among the embodiment one is equally applicable to present embodiment.
In addition, in embodiment one and embodiment two, can carry out the CRC coding to the predefined message that UE sends, to guarantee the correct reception of Node B.
Introduce discontinuous machine-processed embodiment three in the non-scheduled transmission mode below.
In non-scheduled transmission mode, at the UE end timer is set, do not have the time of business data transmission to carry out timing to UE,, promptly start discontinuous mechanism when timer value during more than or equal to the time gate limit value that presets, beginning regularly sends predefined message to Node B, after Node B received predefined message, to UE feedback TPC/SS order, UE kept the connection status of self according to the TPC/SS order by E-HICH, when UE has business data transmission, promptly withdraw from discontinuous mechanism.
Referring to Fig. 4, the flow chart for present embodiment comprises:
Step 401:UE starts the timer that does not have professional transmission, and definite timer expiry;
Step 402:UE regularly sends predefined message to Node B by E-PUCH on the physical resource of reserving;
Step 403:UE receives the TPC/SS order of Node B feedback on corresponding E-HICH, and according to TPC/SS order indication, adjusts transmitting power and keeps synchronously, to keep the connection status with Node B;
Whether step 404:UE has business datum to need transmission, if, withdraw from discontinuous mechanism, otherwise, execution in step 402 returned.
As above-mentioned, embodiment three is this to start the mode of discontinuous mechanism also applicable to scheduled transmission mode voluntarily by UE.
Embodiment four, and this example is in order to illustrate UE after entering discontinuous mechanism, according to the execution mode of the discrete reception of DRX cycle E-AGCH.
In the HSUPA technology, no matter whether UE has uplink strengthening data to need to send, and all needs E-AGCH is carried out continuous must receiving the decode.And the user is not to have data to need to send all the time when using HSUPA professional, therefore when the user does not temporarily have data to send, will bring unnecessary spending to UE if still continue to receive the decode E-AGCH.UE according to the discrete reception of DRX cycle E-AGCH, thereby reaches the purpose of saving electric weight in the present embodiment after entering discontinuous mechanism.Wherein, DRX cycle is disposed by high level.Fig. 5 is the schematic flow sheet of embodiment four, as shown in the figure, the flow process of enforcement can for:

Step 503:UE is according to the data of the discrete reception of DRX cycle E-AGCH;
Step 504:UE sends predefined message on the physical resource of E-AGCH indication, and according to reservation at interval, regularly sends;
In this step, when UE receives the E-AGCH of comprising of Node B of special information, promptly enter discontinuous mechanism, just begin regularly to send predefined message to Node B.
Step 505:UE regularly receives the TPC/SS order on E-HICH, and according to TPC/SS order indication, adjusts transmitting power and keeps synchronously, to keep the connection status with Node B;
In this step, UE orders according to TPC/SS, keeps the connection status of self and Node B, can adopt discontinuous transmission means to save the expense of power and physical resource when the user does not temporarily have data to send.
Does step 506:UE receive discontinuous end E-AGCH? if, execution in step 507, otherwise, execution in step 508;
Step 507:UE sends specific end response message on E-PUCH, withdraw from then;
Does step 508:UE receive other E-AGCH or HS-SCCH information? if, directly withdraw from, otherwise, execution in step 509;
Whether step 509:UE has new business datum to need to send, if, execution in step 510, otherwise, repeated execution of steps 503 returned;
Step 510:UE sends initiatively OPT-OUT NOTICE on E-PUCH;
Whether step 511:UE receives the affirmation feeding back ACK that initiatively withdraws from E-HICH, if, withdraw from, otherwise, execution in step 510 returned.
In the present embodiment, compare with aforesaid embodiment, by the UE that increases according to the discrete mechanism that receives data from E-AGCH of DRX cycle, thereby make when UE does not temporarily have uplink strengthening data to send, UE can carry out discontinuously must receiving E-AGCH, reach purpose of power saving thereby compare original continuous decoding E-AGCH that must receive, thereby prolonged treating the electricity time of UE.
Obviously, embodiment four on the basis of embodiment one has increased the DRX of E-AGCH exactly, and know that easily the mode of DRX is equally applicable to embodiment two.That is, the UE in step 402 regularly before Node B sends predefined message, carries out UE in the embodiment step 503 according to the data of the discrete reception of DRX cycle E-AGCH by E-PUCH on the physical resource of reserving.
