Description
Technical field
The present invention relates to update method, equipment and the system of wireless information update mechanism, particularly system message.
Background technology
At present Universal Terrestrial Radio Access Network network (UTRAN, Universal Terrestril RadioAccess Network) in, subscriber equipment (UE) is meeting active receiving system message when start, this system message is the relevant information of the UE home network that sends of network side, and for example the sub-district ID of UE affiliated subdistrict, public land mobile network ID and timer are provided with etc.The structure of affiliated system message is Master Information Block (MIB, Main Information Block)+Scheduling Block (SB, Scheduling Block)+System information block (SIB, System Information Block).Wherein, among the SIB content of system message, each SIB has label, shows that when label variations corresponding SIB content changes; Be the schedule information of SIB among the SB, promptly obtain corresponding SIB on which running time-frequency resource, same, SB also has label, and the SB content also can cause the variation of SB label; MIB then preserves the label of a plurality of SIB, and when any SIB label changed, the label of corresponding SIB also changed thereupon among the MIB, and MIB also has label, and its label also changes when the MIB content change.
Network side meeting cycle transmitting system message, message content may change.But UE for saves energy and running time-frequency resource, can not receive all system messages again, but only read the SIB that changes after start initiatively receives primary system message.Concrete implementation method is: when system message changed, the SIB that network side can be change produced a new label, thereby also can change label that should SIB among the MIB thereupon, caused the label of MIB also to change; Network side carries the MIB label that changes in the notice that sends to UE; After UE receives this MIB label, compare with the MIB label that from start the time, receives, because the two difference, so on broadcast channel (BCH, Broadcasting Channel), read the content of the MIB that changes; The label of the corresponding SIB that receives when the label of each SIB correspondence is with start among the UE comparison MIB, for the SIB that label changes, UE removes to read this SIB according to the schedule information of this SIB.
But the Long Term Evolution (LTE that is upgrading, Long Term Evolution) in the technology, change has taken place in the structure of system message, no longer adopts the structure of MIB+SB+SIB, and is based on scheduling unit (SU, Scheduling Unit) dispatches, in each SU, comprise a plurality of SIB,, cause the content change of the affiliated SU of this SIB when certain SIB content changes, UE reads content and the preservation of this SU according to the schedule information of this SU.In all SU, there is a main SU, be generally SU1, not only preserve SIB, also have label and/or the schedule information of other SU, UE just can remove to dispatch other SU by main SU.Also BCH has been divided into main broadcast channel (P-BCH) and auxilliary broadcast channel (S-BCH) and/or Dynamic Broadcast Channel (D-BCH) in addition, wherein the characteristic of P-BCH is similar to the BCH among the UTRAN, and the running time-frequency resource that S-BCH/D-BCH takies can be dynamic.
The inventor finds because change has taken place the structure of system message, original update mode in UTRAN can't be suitable fully in LTE, and the existing LTE correlation technique does not give clear and definite explanation to the update mechanism of system message, cause in the discussion scheme of present LTE technology, can't finishing system message update.

Embodiment
Embodiments of the invention send the change information of P-BCH and/or S-BCH by network side in notification message, UE goes to read the system message that changes according to this change information, thereby has realized the system message update in LTE.In one embodiment, variation by S-BCH is set and the variation of P-BCH are separate, network side by concrete which part of notification message bulletin UE changes, thereby the variation that can avoid any system message all can cause UE to begin to read backward from P-BCH, but the part that can directly go to change reads; In another kind of embodiment, the variation that the variation of S-BCH and P-BCH also can be set is independent, the variation of any like this system message all can be presented as the variation of P-BCH, make that network side does not need to distinguish the variation of P-BCH or the variation of S-BCH when sending a notification message, processing method is fairly simple.In an embodiment of the present invention, specifically do not distinguish S-BCH and D-BCH, but the two function is merged, be referred to as S-BCH, in concrete the application, can distinguish according to its characteristic.
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
In an embodiment of the present invention, the carrying content of P-BCH and S-BCH as shown in Figure 1, wherein, P-BCH carrying content is the system information that comprises some physical layer parameters, also comprises the schedule information of SU1, promptly obtains SU1 in which running time-frequency resource.S-BCH then carries a plurality of SU, and in actual applications, the quantity of SU is not limited in 3 shown in Fig. 1.Wherein, in the embodiment of the invention, SU1 is main SU, its structure is different with other SU structure, not only comprise corresponding System information block SIB-1, also comprised the schedule information of other SU, be similar to the SB among the UTRAN, promptly at first to read the schedule information among the SU1, could go to obtain the content of corresponding SU according to this schedule information.
Fig. 2 is the structure of radio frames among the LTE, there is shown the shared running time-frequency resource of each SU, by the schedule information of SU, reads SU on corresponding running time-frequency resource.As can be seen from Figure 2, the System information block in certain SU changes, and network side can send the SU of this renewal on specific running time-frequency resource, and UE reads the content of this SU and preserves on this running time-frequency resource, just finished the renewal of system message.
In embodiment one, it is relatively independent that P-BCH and S-BCH keep, and the variation of S-BCH can not cause the variation of P-BCH, i.e. the variation of both labels is independent of each other.Realize being independent of each other between P-BCH and the S-BCH, can independent label be set for S-BCH, this label is preferably 3 bits; Perhaps P-BCH goes up the label that comprises SU1 in the SU1 schedule information, but can not cause that by the variation of agreement regulation SU1 label P-BCH goes up the carrying content change.In the present embodiment, for S-BCH is provided with independent label, the label equivalence of the label of this S-BCH and SU1, promptly the label of SU1 label and S-BCH all is whether the content that the whole S-BCH of reflection upward carries changes, and the label of SU1 is not set on the P-BCH.Like this, when the System information block among the SU changes, only can cause the label variations of S-BCH and SU1, can not have influence on P-BCH.
Under P-BCH and S-BCH keep relatively independent prerequisite, realize that the renewal of system message has following several mode;
Fig. 3 is the flow chart of first kind of implementation, and in this implementation, each SU is set all the label of oneself, and the part as the schedule information of each SU is placed in other SU schedule information of SU1.Referring to Fig. 3, realize that the first method of system message update specifically comprises the steps:
Any SIB on step 301, the S-BCH changes, and all can cause the change of S-BCH label value, thereby network side can send a notification message, and carries altered S-BCH label value in message.The network equipment that sends this notification message is generally base station (Node-B), by eating dishes without rice or wine this message is sent to UE.Described notification message can be paging (paging) message, layer 1 (L1) layer 2 (L2) control signaling, radio resource control signaling; But be not limited in this message, in theory all be applicable to embodiments of the invention so long as can carry the message of S-BCH label value.
After step 302, UE receive described notification message, resolve this message, therefrom obtain the S-BCH label value that changes.
Step 303, UE compare S-BCH label value and the up-to-date S-BCH label value that obtains and preserve of UE that obtains, if different, then execution in step 304; Otherwise finish more new technological process.
The S-BCH label value that step 304, basis change goes to obtain the system message of renewal.
This acquisition process has four kinds of different implementations, comprising:
If the scheduling mode of SU1 is fixed, the schedule information that is SU1 takies fixing running time-frequency resource, when UE wants to obtain the content of SU1 so, it is just passable only need to go corresponding running time-frequency resource to read, this running time-frequency resource information can be pre-defined by agreement, send to UE after also can be pre-configured, also can store in advance by UE by network side.After UE reads SU1, the label of each SU that compares the label of other SU that stores in the SU1 and self preserve, as change, show that the System information block among the corresponding SU changes, so, go to read corresponding SU on the running time-frequency resource of this schedule information correspondence again according to the schedule information of this SU that stores among the SU1.
If the scheduling mode of SU1 is unfixing, just can't directly go to read the SU1 content this moment.Can be carried the schedule information of SU1 by network side in notification message with the label value of S-BCH, according to this schedule information, UE can directly go corresponding running time-frequency resource to read SU1.After UE reads SU1, the label of the label of other SU that stores in the comparison SU1 and each SU that self preserves, as change, show that the System information block among the corresponding SU changes, so remove to read corresponding SU according to the schedule information of this SU that stores among the SU1 again.
The third mode is that UE removes to read P-BCH, obtains the schedule information of SU1 on P-BCH.According to this schedule information, UE can directly go corresponding running time-frequency resource to read SU1.After UE reads SU1, the label of the label of other SU that stores in the comparison SU1 and each SU that self preserves, as change, show that the System information block among the corresponding SU changes, so remove to read corresponding SU according to the schedule information of this SU that stores among the SU1 again.
Last a kind of mode and aforementioned three kinds of modes are different, no longer are to remove to obtain SU according to SU1, but in the notification message that network side sends, the schedule information of the SU under the label value of S-BCH carries the System information block that changes.After UE receives described notification message, the label of the S-BCH that receives and the respective labels of self preserving are compared,, then remove to read corresponding SU according to the schedule information in the notification message if different.This mode is equal to the label value that does not have SU, because the schedule information of carrying all is the schedule information of the SU that changes.
In actual applications, can make certain variation, adapt to different application above flow process.For example, can no longer carry the label of S-BCH in notification message, but carry the indication information whether S-BCH changes, for example increase by one in system message, this is that the label value that showed S-BCH at 1 o'clock changes, and is to represent not change in 0 o'clock.Certainly, concrete indicating mode is not limited in that this is a kind of, and other is distinguished the indicating mode that whether changes and can use in an embodiment of the present invention in theory.
UE is after receiving this indication information, and the method for obtaining the system message of renewal has four kinds equally, comprising:
If the scheduling mode of SU1 is fixed, after UE received indication information, if indication changes, it was just passable so only need to go corresponding running time-frequency resource to read the label of SU1.If label value changes, remove to read corresponding SU according to the schedule information of the SU that changes that stores among the SU1 again.
If the scheduling mode of SU1 is dynamic, network side can carry the schedule information of SU1 with indication information in notification message.According to this schedule information, UE can directly go corresponding running time-frequency resource to read SU1, removes to read corresponding SU according to the schedule information of the SU that changes that stores among the SU1 again.
The third mode is after UE receives the indication information that S-BCH changes, and removes to read P-BCH, obtains the schedule information of SU1 on P-BCH.According to this schedule information, UE can directly go corresponding running time-frequency resource to read SU1, removes to read corresponding SU according to the schedule information of the SU that changes that stores among the SU1 again.
Last a kind of mode is in the notification message that network side sends, and the indication information that whether changes with S-BCH carries the schedule information of the SU under the System information block that changes.After UE receives described notification message, the label of the S-BCH that receives and the respective labels of self preserving are compared, if different, then UE goes to read the content of corresponding SU according to schedule information.
Fig. 4 is under P-BCH and S-BCH keep relatively independent prerequisite, realizes the flow chart of the second way of system message update, and in this flow process, S-BCH does not have the label of oneself, and this is equivalent to SU1 does not have independent label yet.And each SU except SU1 has the label of oneself, and the part as the schedule information of each SU is placed among the SB of SU1.Referring to Fig. 3, the flow process of this system message update may further comprise the steps:
When any SIB on step 401, the S-BCH changed, network side can send a notification message, and carried the indication information whether S-BCH changes in message.
After step 402, UE receive described notification message, resolve this message, therefrom obtain described indication information.
If this indication information indication of step 403 S-BCH changes, then execution in step 404; Otherwise receive more new technological process.
Step 404, UE go to obtain the system message of renewal.
The system message of obtaining renewal has four kinds of methods equally, comprises respectively:
If the scheduling mode of SU1 is fixed, UE only need go corresponding running time-frequency resource to read the content of SU1 so, and this running time-frequency resource information is can agreement pre-defined, sends to UE after also can network side pre-configured, also can be stored in advance by UE.After UE reads SU1, the label of the label of other SU that stores in the comparison SU1 and each SU that self preserves, as change, show that the System information block among the corresponding SU changes, so remove to read corresponding SU according to the schedule information of this SU that stores among the SU1 again.
If the scheduling mode of SU1 is dynamic, the schedule information that can carry SU1 by the indication information whether network side changes with S-BCH in notification message, according to this schedule information, UE can directly go corresponding running time-frequency resource to read SU1.After UE reads SU1, the label of the label of other SU that stores in the comparison SU1 and each SU that self preserves, as change, show that the System information block among the corresponding SU changes, so remove to read corresponding SU according to the schedule information of this SU that stores among the SU1 again.
The third mode is that UE removes to read P-BCH, obtains the schedule information of SU1 on P-BCH.According to this schedule information, UE can directly go corresponding running time-frequency resource to read SU1.After UE reads SU1, the label of the label of other SU that stores in the comparison SU1 and each SU that self preserves, as change, show that the System information block among the corresponding SU changes, so remove to read corresponding SU according to the schedule information of this SU that stores among the SU1 again.
Last a kind of mode is in the notification message that network side sends, and the indication information that changes with S-BCH carries the schedule information of the SU under the System information block that changes.After UE receives described notification message, label value that receives and the respective labels of self preserving are compared,, then remove to read corresponding SU according to the schedule information in the described notification message if different.
Flow process shown in Figure 4 has realized not having under the situation of label at S-BCH, and the method for the system message of renewal is obtained in realization.And Fig. 5 does not have under the prerequisite of label for S-BCH has label, SU, realizes obtaining the method for updating message, in this flow process, S-BCH has label, equaling SU1 has label, but because other SU does not have label, does not therefore also have the label value of other SU in the SB of SU1.At this moment, the content that is equivalent to the last carrying of S-BCH is as a whole, and any System information block changes, and UE will remove to read the System information block that whole S-BCH goes up carrying.With reference to Fig. 5, then the idiographic flow of system message update is as follows:
Any SIB on step 501, the S-BCH changes, and all can cause the change of S-BCH label value, thereby network side can send a notification message, and carries altered S-BCH label value in message.
After step 502, UE receive described notification message, resolve this message, therefrom obtain the S-BCH label value that changes.
S-BCH label value that step 503, UE are obtained the S-BCH label value that obtains during with start or the S-BCH label value of self preserving when upgrading last time compare, if different, then execution in step 504; Otherwise finish more new technological process.
Step 504, UE read all SU on S-BCH.The mode of reading has following four kinds:
If the scheduling mode of SU1 is fixed, UE reads SU1 on corresponding running time-frequency resource, according to the schedule information of other SU that comprises among the SU1, read all SU on S-BCH.Because there is not the label of other SU among the SU1, so can't knowing the content of which SU, UE changes, can only remove to upgrade all SU according to the schedule information of each SU.
If the scheduling mode of SU1 is dynamic, can in notification message, carry the schedule information of SU1 by network side with the label value of S-BCH, UE goes corresponding running time-frequency resource to read SU1 according to this schedule information, according to the schedule information of other SU that comprises among the SU1, on S-BCH, read all SU again.
The third mode is that UE removes to read P-BCH, obtains the schedule information of SU1 on P-BCH.According to this schedule information, UE directly goes corresponding running time-frequency resource to read SU1.According to the schedule information of other SU that comprises among the SU1, on S-BCH, read all SU again.
Last a kind of mode is exactly in the notification message that network side sends, the schedule information of the SU under the label value of S-BCH carries the System information block that changes, and UE goes to read the content of corresponding SU according to schedule information.
In actual applications, can make variation to above flow process equally, promptly in notification message, no longer carry the label of S-BCH, but carry the indication information whether S-BCH changes, UE is after receiving this indication information, and the method for obtaining the system message of renewal has four kinds equally, comprising:
If the scheduling mode of SU1 is fixed, after UE received described indication information, if indication changes, it was just passable so only need to go corresponding running time-frequency resource to read the label of SU1.If label value changes, UE goes to read the content of all SU according to the schedule information of each SU of SU1.
If the scheduling mode of SU1 is dynamic, network side can carry the schedule information of SU1 with indication information in notification message.According to this schedule information, UE can directly go corresponding running time-frequency resource to read SU1, removes to read corresponding SU according to the schedule information of each SU among the SU1 again.
The third mode is after UE receives the indication information that S-BCH changes, and removes to read P-BCH, obtains the schedule information of SU1 on P-BCH.According to this schedule information, UE can directly go corresponding running time-frequency resource to read SU1, removes to read corresponding SU according to the schedule information of each SU among the SU1 again.
Last a kind of mode is exactly in the notification message that network side sends, the schedule information of the SU under the indication information of S-BCH carries the System information block that changes, and UE goes to read the content of corresponding SU according to schedule information.
Fig. 6 is under P-BCH and S-BCH keep relatively independent prerequisite, realizes the flow chart of the 4th kind of mode of system message update, and in this flow process, S-BCH does not have the label of oneself, thereby SU1 does not have label yet, and other SU except that SU1 does not have label yet.This has just caused system when the notification message that transmitting system message changes, and can't carry the label value of S-BCH.At this moment, referring to Fig. 6, specifically carry out following steps:
When any SIB on step 601, the S-BCH changed, network side can send a notification message, and carried the indication information whether S-BCH changes in message.
After step 602, UE receive described notification message, resolve this message, therefrom obtain described indication information.
If this indication information indication of step 603 S-BCH changes, then execution in step 604; Otherwise receive more new technological process.
Step 604, UE read all SU on S-BCH.
The system message of obtaining renewal has four kinds of methods, comprises respectively:
If the scheduling mode of SU1 is fixed, UE reads SU1 on corresponding running time-frequency resource, according to the schedule information of other SU that comprises among the SU1, read all SU on S-BCH.
If the scheduling mode of SU1 is dynamic, the schedule information that can carry SU1 by the indication information that network side changes with S-BCH in notification message, UE goes corresponding running time-frequency resource to read SU1 according to this schedule information, according to the schedule information of other SU that comprises among the SU1, on S-BCH, read all SU again.
The third mode is that UE removes to read P-BCH, obtains the schedule information of SU1 on P-BCH.According to this schedule information, UE directly goes corresponding running time-frequency resource to read SU1.According to the schedule information of other SU that comprises among the SU1, on S-BCH, read all SU again.
Last a kind of mode is in the notification message that network side sends, and the indication information that changes with S-BCH carries the schedule information of the SU under the System information block that changes, and UE goes to read the content of corresponding SU according to schedule information.
In earlier figures 5 and the described flow process of Fig. 6, other SU except that SU1 does not comprise label, therefore can only read the content of all SU except that SU1 by each the SU schedule information among the SU1 on S-BCH.But in actual applications, can comprise the change information of other SU in the label of SU1 or other content, and send to UE, UE is according to this information and change the schedule information of SU, directly goes to read the content that changes SU, thereby has also further saved more new technological process.
Above-described embodiments of the invention one have been realized the renewal of system message in LTE.And, because it is separate that P-BCH and S-BCH go up the content change of carrying, making network side can directly notify UE is that variation has taken place which content partly, thereby avoided when UE knows that system message changes, need read SU1 by the carrying on the P-BCH, remove finally to read the SU of variation again according to the content of SU1 length by length, so just simplified the flow process of system message update, the system message part that UE directly goes to read variation is just passable.
In embodiment one, a kind of comparatively special method of obtaining update system message is arranged, it is exactly network side directly carries the system message of variation in notification message schedule information, this method does not rely on label, be a kind of comparatively simple method, but need in notification message, carry more information.Perhaps this mode is simplified again, the schedule information of the System information block that network side directly changes, and do not carry any label and indication information.
In above description, it all is system message that S-BCH the goes up carrying update method when changing, in fact, in the content of carrying on P-BCH, also can comprise some system messages, this message content is a physical layer parameter, this part content can not change in the ordinary course of things, but the situation of not getting rid of variation at this moment, also needs the system message on the P-BCH is upgraded.
In concrete implementation, there are following three kinds:
Increase the indication of 2 bits in the label value of notification message or indication information, being used for expression is that P-BCH changes or S-BCH changes, or the two all changes.If indication P-BCH changes, UE directly gets final product to the last read system message of P-BCH so.
P-BCH and S-BCH are set all label, and network side carries the label value and the corresponding schedule information of variation simultaneously when sending a notification message like this.That is,, then only carry the label value of P-BCH and the schedule information of system message if the system message on the notice P-BCH changes in the notification message; If the system message in the notification message on the notice S-BCH changes, then only carry the label value of S-BCH and the schedule information of system message; Perhaps both label values and schedule information are all carried.For UE, need not know label value and schedule information are whose belongs to actually, only need be under the situation that label value changes, the system message of going to obtain renewal according to corresponding schedule information is just passable.
The third method is exactly the schedule information of the direct system message that changes of network side, and UE directly goes to read corresponding system message according to this schedule information.
In embodiments of the invention two, S-BCH has label value, comprises the label of SU1 in the schedule information of the SU1 on P-BCH, and this label equals the label of S-BCH.Simultaneously, the label that in SU1, also comprises other SU.Thereby the variation of the System information block among any SU all can cause the variation of SU1, and then causes the variation of SU1 label value, and this has further brought P-BCH to go up content change again, so the label of P-BCH has also changed.Can find out that by this process P-BCH and S-BCH are no longer separate, the change of the last any system message of S-BCH all can cause the variation of P-BCH.
Embodiments of the invention two are exactly under the not separate situation of P-BCH and S-BCH, realize the renewal of system message.Under different prerequisites, four kinds of different implementation methods are arranged, comprising:
In first kind of implementation, P-BCH and S-BCH have the label of oneself, and the label of S-BCH is equivalent to the label of SU1, and simultaneously, other SU also has the label of oneself.
When system message changed, network side carried the new label value of P-BCH in notification message.After UE receives this message, parsing obtains new label value, and compare with the label value of P-BCH of self storage, if it is different, then read P-BCH, obtain the schedule information of SU1 and the label value of SU1, relatively if the label value of the SU1 of this label value and storage different, then passes through this schedule information, read SU1 again, label value by corresponding SU that the label value of other SU among the SU1 and UE are preserved compares, if different, shows this SU content changing, according to its schedule information, read the System information block among this SU; If identical, then stop the flow process of upgrading.
In second kind of implementation, P-BCH does not have the label of oneself, and S-BCH has the label of oneself, and the label of S-BCH is equivalent to the label of SU1, and simultaneously, other SU also has the label of oneself.
When system message changed, network side carried the indication information that system message changes in notification message.After UE receives this message, resolve and obtain this indication information, so read P-BCH, obtain the schedule information of SU1 and the label value of SU1, relatively if the label value of the SU1 of this label value and storage different, then passes through this schedule information, read SU1 again, label value by corresponding SU that the label value of other SU among the SU1 and UE are preserved compares, if different, shows this SU content changing, according to its schedule information, read the System information block among this SU; If identical, then stop the flow process of upgrading.
