Description
Technical field
The present invention relates to wireless communication technology field, be specifically related to upgrade method, system, wireless access terminal and the network service end of Active Set.
Background technology
The wireless access terminal can be in three kinds of states usually: promptly non-activated state, Idle state and connected state.Non-activated state is meant that generally wireless access terminal (AT) start just catches network, will transfer to a kind of state of Idle state at once; After Idle state is meant that AT catches network, with Network Synchronization and the state that can call out at any time; Connected state then is meant the AT later state that connects.When Idle state, AT manages all pilot tones of receiving automatically; And when connected state, AT and Radio Access Network service end (AN) cooperatively interact all pilot signals are managed.Wherein, when connected state, all pilot signals are divided into Active Set, Candidate Set, Neighbor Set and residual set.Wherein Active Set is exactly when connecting when setting up the pilot signal that all are being served AT; And during connection closed, AT will only monitor the control channel of pilot tone in the Active Set.Candidate Set then is all pilot tone compositions that can enter Active Set at any time, is the candidate of Active Set.The management of general Active Set and Candidate Set all is to be undertaken by certain thresholding, promptly surpasses certain thresholding, then the pilot tone of Candidate Set can be added Active Set, otherwise, the pilot tone of Active Set is moved to the Candidate Set from Active Set.
At 3GPP2 (3
RdGeneration Partnership Project 2,3G (Third Generation) Moblie collaborative project tissue 2) among the evolution items LBC (loose backward compatibility), OFDMA (Orthogonal Frequency Division Multiplexing Access, OFDM) technology is used in preceding reverse data transmission.And preceding reverse data transmission all is to adopt certain particular sector service manner, promptly has forward direction serving sector and reverse serving sector.The foundation that serving sector is selected then is according to sector pilot strength, and combined factors such as sector load consider, is distributed by the AN of sector correspondence.Therefore in LBC, also have the Active Set management, promptly AT may listen to the very strong different sector pilot signals of a plurality of intensity simultaneously, and they are added into the Active Set of AT simultaneously.A kind of AT communicates by letter as shown in Figure 1 with the sector:
AT can measure 3 sectors: sector 1, sector 2 and sector 3, wherein sector 1 is the serving sector of AT, AT will be from the sector 1 receives and sends data so, but because the mobility of AT, AT also must constantly measure the pilot frequency intensity of sector 2 and sector 3, carry out the forward direction service so that select better sector at any time, AT also must send reverse pilot to sector 2 and sector 3 in addition, measure reverse pilot intensity by each sector, and feed back to AT, thereby can select best reverse serving sector.
In the connected state Active Set management of existing LBC realizes, the pilot tone in the Active Set is carried out method for updating as shown in Figure 2:
Step 201, AT send pilot report (PilotReport) message to AN;
AT passes through constantly to measure the forward pilot from adjacent sectors, and reports PilotReport message to give AN, carries out Active Set member's management by AN, i.e. some pilot tone of decision increase enters Active Set or some pilot tone of deletion from Active Set.This is a kind of means of being controlled by AN fully.By thresholding PilotDrop is set, the pilot frequency intensity that detects certain pilot tone as AT is lower than PilotDrop, then start a timer, timing length is PilotDropTimer, if timer expiry, the intensity of this pilot tone is lower than PilotDrop always, and then AT can send PilotReport message to AN, and request AN deletes this pilot tone from Active Set; Even this moment, the intensity of pilot tone was very low, this pilot tone can not be deleted in existing wireless access terminal, and the indication that need obtain AN is just deleted it; Accordingly, AN also needs to provide more system resource to carry out the assignment of Active Set again.
Step 202, AN return resource assignation (MACResourceAssignment) message to AT;
AN determines to delete this pilot tone from Active Set according to the PilotReport message that receives, and by resource allocating message notice AT, just carries out the assignment of Active Set again by message;
Step 203, AT send MACResourceAssignmentComplete (resource assignation response) message to AN;
AT has deleted corresponding pilot tone from Active Set after, notice AN, AN be the corresponding pilot tone of deletion from the Active Set of self maintained also, thereby guarantees that AT is consistent with the Active Set that AN safeguards.
The use said method can be realized the renewal to Active Set, but in some cases, moving for example along with AT, if it is very weak that AT detects the intensity of certain pilot tone, AT still needs by reporting PilotReport earlier, indicate AT to delete this pilot tone by AN down distributing resource assignment again then, processing procedure is more loaded down with trivial details; And new resource allocating message will be carried a lot of control informations, has caused more command transmitting expense; And when issuing new resource allocating message, AN does not delete the processing of pilot tone in the Active Set, but after will waiting the response message of the resource assignation of receiving that AT sends, AN just can delete the pilot tone in the Active Set of self maintained, has further strengthened the fussy degree of handling; Further, the ineligible pilot tone of deletion from Active Set that existing wireless access terminal can not be initiatively, and the indication that must obtain AN could be deleted it, has strengthened the complexity of handling; Accordingly, AT can not initiatively delete pilot tone, will inevitably cause the processing complexity of AN, makes existing AN need more processing resource to indicate AT that pilot tone is deleted.

Embodiment
For make purpose of the present invention, technical scheme, and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
Referring to Fig. 3, first embodiment of method provided by the invention mainly comprises:
The deletion condition that presets can have multiple situation, for example the intensity of pilot signal a little less than, perhaps pilot signal loses and situation such as the forward direction of sector is synchronous; This specification all is to adopt the situation monitor a pilot tone to describe, and meets the deletion condition that presets if monitor a plurality of pilot tones simultaneously, and the processing mode of processing mode during also with one is identical, below more weak with the intensity of pilot signal be that example describes:
Under the connected state situation, the forward direction of a plurality of sectors keeps synchronously in AT and the Active Set, and monitor forward pilot from a plurality of sectors, measure the signal strength signal intensity of these pilot tones, in the ordinary course of things, estimation pilot signals intensity can use Ec/Io to represent, i.e. the ratio of the pilot energy that receives on the chip of unit and all received signal spectrum densities; Generally speaking, AT also can carry out signal processing to these pilot frequency intensities, such as filtering.By the measurement in a period of time, if AT finds the signal strength signal intensity of some Active Set pilot tone and is lower than the deletion thresholding (PilotRemove) that presets, PilotRemove is different with PilotDrop, in general, the value of the ratio PilotDrop that the value of PilotRemove is provided with is little, if pilot frequency intensity less than the value of PilotDrop but greater than the value of PilotRemove, can also handle this moment according to the flow process of prior art, the last deletion of Pilot is just determined by AN; If the value of Pilot is less than the value of PilotRemove, then AT can delete this Pilot immediately from Active Set; Equal the situation of the value of PilotRemove as for the value of Pilot, can directly delete also and can directly not delete, this can be provided with as the case may be by the technical staff;
Certainly, this is the implementation of a kind of comparative optimization provided by the invention, in actual applications, also PilotRemove directly can be replaced PilotDrop, the technical scheme that just adopts the embodiment of the invention to provide replaces prior art fully, just directly deletes less than the PilotRemove that presets as long as record the intensity of Pilot;
Satisfy the deletion condition that presets if AT records described pilot tone, the intensity of pilot tone is less than the PilotRemove that presets as described, and perhaps described pilot tone has lost with the forward direction of sector synchronous, all with described pilot tone described pilot tone of deletion from the Active Set that described AT safeguards;
The information notice AN of the described pilot tone that step 303, described AT will delete;
Can increase a pilot tone deletion message newly, carry the sign of waiting to delete pilot tone in the message, can be with this message called after PilotRemove, the sign that waiting of carrying in message deleted pilot tone comprises the PN (PilotPN) and the carrier wave ID (CarrierID) of pilot tone, PilotPN and CarrierID can uniquely determine a pilot tone, therefore only need in PilotRemove message, carry PilotPN and CarrierID and necessary communication information, thereby reduce unnecessary signaling transport overhead; Though with message called after PilotRemove, embodiments of the invention do not limit message name herein;
Further, the invention provides another execution mode, with the information notice AN of the pilot tone of deletion; This mode does not need to increase new message, but realizes on the basis of existing procedure; As shown in table 1, be the form of PilotReport message in the existing procedure:
Table 1, existing PilotReport message format
Existing P ilotReport message is made amendment, for example can increase the Removed field newly before the Keep field, this fields account is with a bit, and when the Removed field was 1, expression AT was with this pilot tone deletion; If the Removed field is 0, represent that then AT does not delete this pilot tone, do by AN and further indicate whether to delete this pilot tone; Present embodiment does not get rid of that to use the Removed field be that 0 expression is deleted, and adopt field be 1 o'clock be not deleted situation;
Amended PilotReport message format is as shown in table 2:
Table 2, PilotReport message format provided by the invention
Table 2 is a kind of message format scheme of providing of present embodiment just, and present embodiment also is not precluded within other positions and adds the field of other field names and represent whether AT deletes this pilot tone;
After AN receives the information of pilot tone of the deletion that AT sends, the corresponding pilot tone of deletion from the Active Set of self maintained;
If what AN received is the PilotRemove message that increases newly, the pilot tone of the unique definite needs deletion of the PilotPN that carries according to described message and two fields of CarrierID just;
If what AN received is original PilotReport message, judge then whether newly-increased field Removed is 1, if Removed is 1, represent that then AT has deleted corresponding pilot tone, just according to the pilot tone of PilotPN in the PilotReport message and the unique definite needs deletion of two fields of ChannelBand, wherein ChannelBand and CarrierID are one to one to AN;
In first embodiment of method provided by the invention, when AT records a pilot tone and meets the deletion condition that presets, directly from Active Set, delete this pilot tone, reinforming AN deletes described pilot tone, thereby adopt simple process flow to realize pilot tone is deleted, further, because flow process reduces, also reduced signaling and transmitted needed expense; In a kind of implementation of first embodiment, adopted newly-increased message PilotRemove, in this message, only carried several fields of minority, further reduce signaling and transmitted needed expense.
In actual applications, AN has deleted corresponding pilot tone from Active Set after, will return an acknowledge message to AT, notice AT deletes described pilot tone, thereby the Active Set that makes AT confirm that AT and AN safeguard respectively is consistent; If described pilot tone belongs to the serving sector into described AT service, then AN can directly notify described AT the corresponding pilot tone of deletion from Active Set by described serving sector; If described pilot tone belongs to the non-serving sector into described AT service, then described AN need will delete the information of corresponding pilot tone by described non-serving sector from Active Set, be transmitted to serving sector, by described serving sector information be transmitted to described AT again for described AT service.
At two kinds of implementations among first embodiment, AN is to there being dual mode notice AT: if AT uses the PilotRemove notice AN that increases newly, then the pilot tone deletion response message that increases newly of the use of AN correspondence returns to AT, for example can be with described pilot tone deletion response message called after PilotRemoveRsp; If AT is to use existing P ilotReport message, by newly-increased Removed field in described PilotReport message, after AN receives PilotReport message, judge whether the value of Removed field represents that AT has deleted corresponding pilot tone, if not, AN handles according to the normal flow of prior art; If AN also deletes corresponding pilot tone, and adopts existing MACResourceAssignment message informing AT, do not get rid of the situation that adopts newly-increased message that AT is notified certainly yet.
Referring to Fig. 4, method second embodiment provided by the invention mainly may further comprise the steps:
The information of the described pilot tone that step 403, described AT will delete and the deletion reason notice AN corresponding with the described deletion condition that presets;
The deletion reason can increase a deletion cause field in PilotRemove message described in method first embodiment or PilotReport message, the length of field can be set according to the quantity of known deletion reason; Give an example, if known have two kinds to delete reasons, then can field length be set to 2, represent not delete with 00,01 expression pilot frequency intensity is too low, and 10 expression pilot tones have lost with the forward direction of sector synchronous, and 11 represent the unknowns of deletion reason; After AN receives message, just can know corresponding deletion reason according to the value of deletion cause field; Certainly do not get rid of the situation that adopts a new message to send the deletion reason separately yet;
After AN receives the message of AT transmission, determine the deletion reason, and trigger the processing of the sector work correspondence of described pilot tone correspondence according to the value of deletion cause field in the message; For example, if the deletion reason is that pilot frequency intensity is too low, just strengthen transmitting power; If lose with the forward direction of sector synchronous, Adjustment System time then; Thereby make the sector do corresponding processing, avoid occurring once more identical situation;
After AN has deleted corresponding pilot tone, notice AT, thus make AT know that the Active Set of the two is consistent;
In a second embodiment, AT will delete the reason notice AN of pilot tone, thereby corresponding processing is done in the sector that makes AN trigger described pilot tone correspondence, has avoided taking place once more identical situation.
AT and sector pilot tone constantly communicate, the sector pilot tone is normal with communicating by letter of AT in order to guarantee, being necessary for described AT distributes some resources to ensure normally carrying out of communication, the MACID that distributes for AT for example, MAC ID is that the sector pilot tone is used for the described AT of unique identification, also has other to ensure other necessary resource that communication is normally carried out certainly; But the resource of sector pilot tone is limited, AT has deleted a pilot tone from Active Set after, can not communicate with this pilot tone again, thereby this pilot tone is that the described AT resource of distributing is just of no use, so in order to save the resource of sector pilot tone, the 3rd embodiment provided by the invention also comprises step AT has deleted pilot tone from Active Set after:
Described AT notifies the sector of described pilot tone correspondence to be released to the resource that described AT distributes.
After the sector had discharged the resource of distributing for described AT, the sector can be other AT service with these resources, thereby has guaranteed making full use of of sector resources.
The a plurality of pilot tones of AT possibility while with a plurality of sectors communicate, and are serving sector but simultaneously a sector can only be arranged, and other sector then is non-serving sector;
That Fig. 5 describes is the 3rd embodiment of method provided by the invention, and what mainly describe is the situation that pilot tone belongs to the non-serving sector of AT:
Step 501, AT monitor a pilot tone that belongs to non-serving sector and meet the deletion condition that presets;
Step 502, AT delete described pilot tone from Active Set, and the information of described pilot tone, deletion reason and the described non-serving sector corresponding with described deletion condition are identified the serving sector that sends to AT;
As long as described non-serving sector sign be can the described non-serving sector of unique identification information can, as sector ID etc.;
Step 503, described serving sector are transmitted to described non-serving sector according to described non-serving sector sign with the information of described pilot tone and the deletion reason corresponding with described deletion condition;
Here only described serving sector and can directly information be transmitted to the situation of described non-serving sector, but not getting rid of serving sector can not directly be transmitted to information described non-serving sector, and need be through situation about repeatedly transmitting;
Step 504, described non-serving sector from being the described pilot tone of deletion the Active Set of described AT service, are done corresponding processing according to described deletion reason according to the information of described pilot tone;
As from the foregoing, when pilot tone belongs to the non-serving sector of AT, can information be transmitted to described non-serving sector, thereby the renewal of Active Set can be carried out smoothly by serving sector;
Further, the resource that non-serving sector is released to the AT distribution also triggers by serving sector, as shown in Figure 1:
Suppose that serving sector is sector 1, AT has deleted a pilot tone of sector 2 from Active Set; This moment AT can not with sector 2 direct communications, so AT has deleted a pilot tone of sector 2 from Active Set after, earlier notice sector 1 is released to the resource that described AT distributes by 1 notice sector 2, sector again, thereby the limited resources of sector 2 can be fully utilized.
