Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to connection identifier method for updating in a kind of parameter information and the system's soft switching process.
Background technology
IEEE802.16e is a mobile wide-band wire-less accessing system standard in formulation process just.Described wireless access system comprises BS (base station) and two elements of MSS (portable terminal), the intercommunication of BS and MSS is not through wired passage, but the electromagnetic wave that transmits and receives by radio receiving-transmitting unit wirelessly communicates.Each radio receiving-transmitting unit all has certain coverage, if exceeded coverage, communication will be interrupted.
In wireless receiving system, a BS can communicate with a plurality of MSS in its coverage.BS and each MSS at first will set up a passage in logic before communicating, usually this logical channel is called connection.Connect to set up good after, both sides just can be in this connection Data transmission.Can there be many connections simultaneously between a BS and a MSS, be used for transmitting data of different types.
Every between BS and MSS is connected all and comes unique identification by an identifier, and this identifier just is called CID (connection identifier).CID is distributed when every connection is set up by BS.The CID of many connections of setting up between a plurality of MSS in same BS and its coverage can not repeat.
The limited coverage area of each BS, still a plurality of BS link together with certain rule and just can constitute covering wireless communication networks in a big way.In wireless communication networks, because MSS is movably, and BS is fixed, thus along with MSS move pass the overlay area of different B S the time, its can constantly change the BS that communicates with, to guarantee communication continuity, this process is called switching.Described switching generally includes direct-cut operation and software switches.
Described software switches and is meant: in particular cases when a MSS moves to the crossover region of a plurality of BS coverages, it may keep simultaneously communicating by letter with a plurality of BS at some, and these BS have just constituted the Active Set of this MSS.The content of communicating by letter between a plurality of BS in MS and the Active Set is identical, and the BS that promptly is in the Active Set is identical to the data that MSS sends, and the data that receive from MSS are also identical.Though soft handover has increased the complexity and the expense of system to a certain extent, can bring to the known diversity of correlative technology field personnel merges and gain.
Along with moving of MSS, communication quality between it and each BS changes taking place, so the BS in the Active Set also will be along with corresponding renewal be done in variation, the bad BS of those signal qualitys can delete from Active Set, and the BS that those signal qualitys are good then will add Active Set.
In activating set updating, also may be accompanied by the renewal of CID.This is that the data that receive from MSS are also identical because the BS that is in the Active Set is identical to the data that MSS sends.The front had said that the transmission of data need be based on certain connection, so for same type data, the connection of setting up between a plurality of BS in the Active Set and the MSS is identical, the CID of each connection also is identical.But the content of Active Set is not unalterable, and when new BS added Active Set, the cover CID that other BS that it need adopt and Active Set is interior are identical identified many connections between own and this MSS.Distributed to and being connected that other MSS is set up but may newly add these CID of BS hereto, can not be repeated to use by it.This moment, the BS in the Active Set just need reselect the CID of any one BS use in some collection that are not activated at present for fear of the conflict of CID, identified and carried out connection between the MSS of soft handover with these CID.
In existing draft standard, when carrying out activating set updating, soft handover need send handoff request/response message.If in activating set updating, also will carry out the renewal of CID, will in handoff request message MOB_BSHO-REQ that BS sends and switching response message MOB_BSHO-RSP, comprise the content that CID upgrades so.
That is to say that the implementation method that adopts is exactly the old CID that lists all initiate CID and remain in the administrative messag of handoff request/response at present.MSS receives that this administrative messag just can obtain later to upgrade a later cover CID.
Each CID has certain length, and the CID that lists is many more, and the length of administrative messag is just long more, and therefore, the above-mentioned method of upgrading CID in administrative messag will make the expense of administrative messag increase.
Because the transmission of administrative messag need expend interface-free resources, and interface-free resources is limited, therefore, the length of administrative messag is long more, and it is many more then to be used for transmitting the resource that administrative messag expends, and the interface-free resources of remaining Gong transmission valid data is just few more.
That is to say, currently used method each all in administrative messag all initiate CID and complete the listing of old CID that remain, greatly wasted limited empty resource.
Summary of the invention

Embodiment
The core of the method for undated parameter information provided by the invention is: the form of determining at least two kinds of undated parameter management of information message in communication system; Afterwards, when needs undated parameter information, calculate the network overhead of various form management message correspondences in this undated parameter information process; At last, the administrative messag form according to the network overhead Information Selection network overhead minimum of calculating carries out the transmission of needs updated parameters information, the renewal of realization parameter information.Thereby guarantee effectively to save when carrying out parameter information in network upgrades the resource in the network.
To be treated to example to the renewal of the cid information in the soft switch processing procedure in the wireless communication system below, the present invention will be described.
In the soft switch processing procedure, the renewal of CID replaces the old CID of a part with regard to being meant with new CID.When carrying out the CID renewal at every turn, in fact only need indicate the CID that really changes by administrative messag, and in the CID that changes, have only those initiate CID to need complete listing, old CID that is replaced and the old CID that remains that does not change then just knew the CID that these are old originally owing to MSS, therefore, can selectively it be listed in the administrative messag according to actual conditions fully, or indicate by the method that other is more saved.
Purpose of the present invention changes the indicating means that CID upgrades in the administrative messag just, shortens administrative messag length thereby reach, and saves the purpose of interface-free resources.
The present invention proposes new CID and upgrade indication scheme, the actual conditions that this scheme is upgraded according to each CID, select a kind of method of optimum to carry out CID renewal indication, promptly select best administrative messag form to carry out CID and upgrade processing, and set up corresponding indicating bit to show method selected.

Under the superincumbent principle of the present invention, concrete provided a kind of scheme at handoff request and response message: MOB_BSHO-REQ and MOB_BSHO-RSP, in this scheme, the number of the CID that uses between BS and the MSS when supposing soft handover is N, wherein needing the number of the CID that upgrades is M, and the length of each CID is L.
The specific implementation of method of the present invention specifically may further comprise the steps as shown in Figure 1:
Step 11: in wireless communication system, determine that BS need send handoff request message to MSS;
Step 12: the quantity of the CID that uses between the BS side is determined itself and this MSS is N, and the CID quantity that this need upgrade is M, and the length of each CID is L;
Step 13: according to above-mentioned each parameter value, promptly N, M, L calculate the overhead value of the various administrative messag form correspondences that are used to upgrade;
The invention provides the building method that three kinds of CID upgrade Indication messages, with and corresponding overhead computational mode, be specially:
(1) method that adopts binary bits to light indicates the more new situation of each CID, the meaning that bit is lighted is exactly: each bit represents a CID, if certain bit equals " 1 ", represents that then its corresponding CID is replaced, if equal " 0 ", it is constant to represent that then its corresponding CID keeps;
Total total N bit, this N bit from a high position to the low level according to certain rule (such as from small to large) corresponding to this N CID; Equal " 1 " bit for each, that is to say the CID that is replaced for each, at structure during administrative messag, the new CID after need providing it in a certain order and replacing;
Make the expense of carrying out the CID renewal in this way be: N+M * L, when the CID number was fewer, the expense of this method was less usually;
(2) method that adopts call number to identify sorts an original N CID in a certain order, is numbered according to the result who sorts, and obtains certain call number, and the length of each call number is: ceil (LOG
2(N));
When the structure administrative messag, the new CID after the call number of listing each CID that is replaced in the administrative messag and replacement thereof;
Make the expense of carrying out the CID renewal in this way be: (ceil (LOG
2(N))+L) * M; Usually more in the CID number, and the CID that need upgrade is more after a little while, the expense of this method can be less;
(3) adopt old CID that in administrative messag, lists reservation and the method for replacing later new CID, the administrative messag form in the promptly existing renewal CID process;
Make the expense of carrying out the CID renewal in this way be: L * N, when total number of CID and the CID number that needs to upgrade were all many, the expense of this method was less usually;
When needs carry out CID renewal processing, then can in above-mentioned three kinds of methods, select a kind of suitable method to carry out the renewal operation of CID according to the size of expense;
Step 14: the overhead value of three kinds of methods that relatively calculate, and a kind of method of selection overhead value minimum, promptly select the form of administrative messag of a kind of method correspondence of overhead value minimum, afterwards, just can utilize the administrative messag of this method correspondence to carry out the renewal of CID;
That is to say, need carry out CID when upgrading at every turn, calculate the overhead value of three kinds of methods above-mentioned (1), (2) and (3) listing respectively according to top account form, and therefrom select the sort of indicating means of expense minimum;
Step 15: according to the administrative messag structure handoff request or the response message of the method correspondence of overhead value minimum, and send to corresponding M SS, describe in front (1) of concrete message constructing mode, (2) and (3);
For guaranteeing that the MSS end can be after receiving described administrative messag, can accurately carry out the renewal of CID handles, corresponding C ID also need be set in described administrative messag in this step upgrade designator CID_Update_Ind, be administrative messag form indication information, being used to indicate this administrative messag, concrete what adopt is any administrative messag form;
For example can adopt following indicator information:
When CID_Update_Ind=0, adopt (1) described method;
When CID_Update_Ind=1, adopt (2) described method;
When CID_Update_Ind=2, adopt (3) described method;
Certainly, also can adopt other concrete indicator information, as long as on MSS, can know the message format that this administrative messag adopts.
Step 16:MSS receives described administrative messag, and promptly handoff request message is upgraded the form that designator is determined message according to the CID in the message, and therefrom takes out the cid information that upgrades, and upgrades processing to carry out corresponding C ID;
In this step, after the CID renewal is finished, then return switching response message to BS.
Through the processing procedure of above-mentioned steps 11, realized that the renewal of the CID in the wireless communication system is handled to step 16.
Method of the present invention can also be used for the renewal of other similar message, as at the renewal of SAID (Security Association sign) information etc., to realize reducing network overhead, saves the purpose of Internet resources.
In sum, method of the present invention can guarantee that each CID upgrades and can both adopt optimum relatively method to carry out CID to upgrade indication, to reach Compression manager message, save the purpose of interface-free resources.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
