Embodiment
Basic thought of the present invention is: when system message changes; Utilize PCH can be mapped to the characteristic of descending shared physical resource; Direct transmission system information on PCH, and come indicating system message whether to change through on descending shared physical control channel, sending special identifier.
Wherein, said directly transmission system information on PCH can be the system message after directly transmission changes on the PCH, also can be that transmission transmits the running time-frequency resource position that changes the back system message on PCH.That is to say that system message information is for the system message after changing or for transmitting the running time-frequency resource position that changes the back system message.
The special identifier that said descending shared physical control channel carries, the retention that can directly utilize existing PI to indicate also can utilize retention special among the UE ID.Generally, if descending shared physical control channel carries is special identifier, just directly variation has taken place in illustrative system message.But accuracy in order to ensure indication; And, the corresponding relation between special identifier and the system message version information can further be set, the system message version that different special identifier are corresponding different in order to confirm that system message changes the difference of front and back version; Set corresponding relation is prenoticed UE by the base station; Like this, just can further obtain the system message version that PCH goes up transmission, and the system message version of system message version that is obtained and UE self storage is compared through the special identifier of receiving; If different, just confirm further that variation has taken place system message really.The present invention can also increase a system message version field, and when system message changes, special identifier is sent with the system message version field; So, UE can further obtain the system message version that carries in the system message version field after receiving special identifier; Afterwards; If the system message version of the system message version that is relatively obtained and self storage different, just confirms further that variation has taken place system message really.
Among the present invention, said descending shared physical resource can be various DSCH Downlink Shared Channels, such as: layer one/layer two (L1/L2) scheduling controlling channel, Physical Downlink Shared Channel, Physical Random Access Channel etc.So-called running time-frequency resource position is meant the physical resource that is used for transfer system message that distributes through the mode of fixed time and frequency, such as specifying the system message after changing to send on the frequency range of f2 at f1 in the period of t2 at t1.
Below combine Fig. 1, Fig. 2 and specific embodiment respectively, further explain concrete implementation of the present invention.
Embodiment one:
In the present embodiment, said system message information is the system message after changing, and the system message after the base station will change directly is placed on PCH and goes up transmission, and said special identifier is the retention of PI indication, i.e. special P I indication.As shown in Figure 1, realize in the present embodiment that the method for system message update may further comprise the steps:
Step 11: if system message changes; The base station is when dispatching PCH through descending shared physical control channel; Confirm that a special P I indication substitutes common PI indication and on descending shared physical control channel, sends with broadcast mode, the transmission location of system message is placed on confirm PI and indicates in the resource indication territory on the corresponding descending shared physical control channel; And the system message after the base station will change directly is placed on PI indicates corresponding PCH to go up transmission.
Here, said special P I indication is adopted with PI and is indicated identical form and definition, can directly adopt the retention of PI indication, and the special P I that is adopted indication can not be as the paging of normal users.When transmission, special P I indication just is placed on the position of transmitting common PI indication.For the base station, when dispatching PCH through descending shared physical control channel, if system message changes, descending shared physical control channel just sends special P I indication.
Generally, can reserve the retention of a plurality of PI, the retention of each reservation can corresponding different system message change, such as: different change in information etc. in the indicating system message.
Certainly; In the present embodiment, said special identifier also can adopt special UE ID value, that is: the retention of UEID; Take 16 bits; Adopt and identical form of UE ID and definition, but called after system message variation-Radio Network Temporary Identifier (SIC-RNTI, System Information ChargeRNTI).
As for concrete which kind of retention that adopts in practical application, consult in advance by base station and UE both sides, or confirm to prenotice UE's by the base station.Like this; For the sign that send on descending shared physical control channel the base station, UE receives whether the back just can be judged according to occurrence is special identifier, promptly whether is special P I indication or SIC-RNTI; If belong to special P I indication or SIC-RNTI, then illustrative system message changes.Concrete judge be: UE is indicated with one or more special P I of oneself knowing in advance by the ident value of receiving or the SIC-RNTI value compares, if be included in wherein, is exactly special identifier.
The descending shared physical control channel of step 12～15:UE demodulation; Judge whether the sign of receiving is special identifier; If illustrative system message changes, then UE reads the information on the PCH according to the result of the descending shared physical control channel of demodulation to the position of indication; Directly obtain the system message after the variation of transmitting on the PCH; That is: the resource indication territory of UE through the descending shared physical control channel of demodulation obtains the transmission location of system message, and UE is indicating on the corresponding PCH with special PI then, directly reads the system message after the variation to the transmission location that is obtained; If not, illustrative system message does not change, and then finishes current handling process.

Here, said special identifier can be special P I indication or SIC-RNTI, and concrete using is identical with the description in embodiment one step 11 with qualification.When reality was used, what can also be further distinguish that PCH goes up transmission through the difference of special identifier value was system message, or the running time-frequency resource position.Such as: confirm 8 retentions of PI usable levels as special identifier; Wherein 4 are used to represent the system message after directly transmission changes on PCH when system message changes, and all the other 4 are used to represent when system message changes that transmission transmits the running time-frequency resource positions that change the back system message on PCH.Certainly, also can not do this differentiation, but consult by base station and UE in advance, when system message changes, adopt which kind of advice method.
The descending shared physical control channel of step 22～26:UE demodulation; Judge whether the sign of receiving is special identifier, if illustrative system message changes; Then UE reads the information on the PCH according to the result of the descending shared physical control channel of demodulation to the position of indication; To transmit change the running time-frequency resource position of back system message, that is: UE is through the transmission location of the resource indication territory acquisition running time-frequency resource position of the descending shared physical control channel of demodulation, then UE with the corresponding PCH of special identifier on; Read the running time-frequency resource position to the transmission location that is obtained, to the running time-frequency resource position that is obtained, receive the system message after changing again afterwards; If not, illustrative system message does not change, and then finishes current handling process.
Embodiment three:
In the present embodiment; Said system message information is the system message after changing, and the system message after the base station will change directly is placed on PCH and goes up transmission, and said special identifier is the retention of PI indication; It is special P I indication; And in the present embodiment, the base station is provided with the corresponding relation between different special PI indications and the different system message version in advance, and set corresponding relation is prenoticed UE.As shown in Figure 3, realize in the present embodiment that the method for system message update may further comprise the steps:
Step 31: if system message changes; The base station is when dispatching PCH through descending shared physical control channel; Confirm that a special P I indication substitutes common PI indication and on descending shared physical control channel, sends with broadcast mode, the transmission location of system message is placed on confirm PI and indicates in the resource indication territory on the corresponding descending shared physical control channel; And the system message after the base station will change directly is placed on PI indicates corresponding PCH to go up transmission.
Here, said special identifier can be special P I indication or SIC-RNTI, and concrete using is identical with the description in embodiment one step 11 with qualification.
The descending shared physical control channel of step 32～37:UE demodulation judges whether the sign of receiving is special identifier, and if not special identifier, illustrative system message does not change, and then finishes current handling process; If special identifier; Then UE obtains the system message version of current system for transmitting message, then according to the special PI indication of self storage and the corresponding relation between the system message version; Whether the system message version that is relatively obtained is identical with the system message version of self storage; If the system message version is different, then illustrative system message changes, and UE reads the information on the PCH according to the result of the descending shared physical control channel of demodulation to the position of indication; Directly obtain the system message after the variation of transmitting on the PCH; That is: the resource indication territory of UE through the descending shared physical control channel of demodulation obtains the transmission location of system message, and UE is indicating on the corresponding PCH with special PI afterwards, directly reads the system message after the variation to the transmission location that is obtained; If the system message version is identical, then finish current handling process.
Wherein, the system message version of UE self storage comes from the broadcast of reception, carries the system message version information in the broadcast, just is stored in self after UE receives at every turn.
Embodiment four:
In the present embodiment; System message information is for transmitting the running time-frequency resource position that changes the back system message; The base station is transmitted on PCH and is transmitted the running time-frequency resource position that changes the back system message; And the base station is provided with the system message version field of carrying the system message version, sends with broadcast mode on descending shared physical control channel with special identifier.As shown in Figure 4, realize in the present embodiment that the method for system message update may further comprise the steps:

Here, said special identifier can be special P I indication or SIC-RNTI, and concrete using is identical with the description in embodiment one step 11 with qualification.When reality was used, what can also be further distinguish that PCH goes up transmission through the difference of special identifier value was system message, or the running time-frequency resource position.Such as: confirm 8 retentions of PI usable levels as special identifier; Wherein 4 are used to represent the system message after directly transmission changes on PCH when system message changes, and all the other 4 are used to represent when system message changes that transmission transmits the running time-frequency resource positions that change the back system message on PCH.Certainly, also can not do this differentiation, but consult by base station and UE in advance, when system message changes, adopt which kind of advice method.
The descending shared physical control channel of step 42～48:UE demodulation judges whether the sign of receiving is special identifier, and if not special identifier, illustrative system message does not change, and then finishes current handling process; If special identifier; Then obtain the system message version of current system for transmitting message the system message version field of UE from descending shared physical control channel, afterwards, whether the system message version that is relatively obtained is identical with the system message version of self storage; If it is different; Then illustrative system message changes, and UE reads the information on the PCH according to the result of the descending shared physical control channel of demodulation to the position of indication, obtains to transmit the running time-frequency resource position that changes the back system message; That is: UE obtains the transmission location of running time-frequency resource position through the resource indication territory of the descending shared physical control channel of demodulation; Then UE with the corresponding PCH of special identifier on, read the running time-frequency resource position to the transmission location that is obtained, receive the system message after changing afterwards again to the running time-frequency resource position that is obtained; If identical, then finish current handling process.
Wherein, the system message version of UE self storage comes from the broadcast of reception, carries the system message version information in the broadcast, just is stored in self after UE receives at every turn.
In practical application, the scheme of embodiment three also can adopt increases the mode that the system message version field is set, and embodiment four also can adopt the mode that special identifier and system message version corresponding relation are set.
For realizing said method, the present invention increases the sign judgement unit in UE, is used for confirming whether the sign from descending shared physical control channel demodulation is special identifier, if then the notification message Transmit-Receive Unit is gone up to PCH and received the corresponding system information.Concrete operations are: existing information receiving and transmitting unit reads the sign of transmission from descending shared physical control channel among the UE; With the sign judgement unit that sends after the sign demodulation; Judge by the sign judgement unit whether the sign of receiving is special identifier; To confirm whether system message changes; If read system message information is gone up to the PCH of indication in the information receiving and transmitting unit that the sign judgement unit is just notified UE, that is: the system message after the variation or read and transmit the running time-frequency resource position that changes the back system message.Store all available special identifier values that indicating system message changes in advance in the sign judgement unit.
The sign judgement unit can also be further according to the special identifier of receiving; Obtain current system for transmitting message version; Afterwards; The system message version of storing in the system message version that is obtained and self the existing memory cell is compared,, reinform the information receiving and transmitting unit and go up reception corresponding system information to PCH if different.Perhaps; After the sign judgement unit is confirmed to be special identifier; The notification message Transmit-Receive Unit further obtains the system message version in the system message version field, and the information receiving and transmitting unit sends to the sign judgement unit after reading the system message version, and the sign judgement unit compares the system message version of storing in the system message version that is obtained and self the existing memory cell; If different, reinform the information receiving and transmitting unit and go up reception corresponding system information to PCH.
