The selection of composition carrier wave

First embodiment

In this application, the carrier wave used for terminal and base station in carrier convergence communication network is known as available carrier wave. Terminal is referred to as composition carrier wave (component carrier) in the carrier wave used, and composition carrier wave is also available carrier wave.Work The composition carrier wave for making the terminal under carrier convergence pattern includes main composition carrier wave (PCC, primary a component ) and at least one second composition carrier wave (SCC, secondary component carrier) carrier.

In carrier convergence communication network, base station and terminal may be used the carrier wave positioned at different frequency range and communicated.It is right Often there is variation in the coverage area of the different carrier wave of frequency range, antenna for base station.In consideration of it, the application is proposed for not Same coverage area distribution pattern, using different composition carrier wave selection strategies.

Therefore, as shown in Figure 1, providing a kind of method selecting composition carrier wave in carrier convergence communication network, including： Determine the coverage area (step 102) for each available carrier wave that terminal can use；Determine point of the coverage area of each available carrier wave Whether cloth meets predetermined distribution pattern (step 104)；In the case where meeting the predetermined distribution pattern, according at least to described point The criterion that cloth pattern is determined determines composition carrier wave (step 106) to be used.

The coverage area of all available carrier waves of base station is known for base station.Therefore, the position based on terminal, The coverage area for each available carrier wave that terminal can use can be obtained.Obviously, terminal can use certain available carrier wave, refer to Terminal is within the coverage area of the available carrier wave.The position of terminal both can be by multiple base stations united positioning, also can be by terminal It is determined and provided to base station by means of global position system such as GPS (global positioning system).

As previously mentioned, the application proposes to adjust composition carrier wave selection strategy according to the distribution pattern of coverage area.This Shen Three kinds of possible application scenarios please be contemplate, it is as in Figure 2-4 respectively, different compositions can be used under each scene Carrier wave selection strategy.Certainly, one of which either two kinds of application scenarios or the more applications of consideration also can be only considered completely Simultaneously more selection strategies are arranged in scene.For simplicity, in the application examples cited, only there are two types of available carrier waves, still There can be multiple available carrier waves in practical applications.

The first application scenarios, that is, the first available carrier wave coverage area distribution pattern are as shown in Figure 2.In the distribution In pattern, each base station 210,220,230 uses two kinds of carrier waves F1 and F2, and the corresponding cell coverage area base of F1, F2 respectively It is overlapped on this, is capable of providing roughly the same overlay area.In this case, F1 and F2 is likely located at identical carrier frequency band It is interior, it is typical continuity carrier convergence.

Under the application scenarios, if terminal 250 in cell coverage area, then covering in two kinds of carrier waves F1, F2 simultaneously Within the scope of lid.Therefore, in this case, if not considering other conditions, two kinds of carrier waves F1, F2 have par, can Arbitrarily to select one carrier wave F1 of any of which, either F2 considers as new composition carrier wave or further other conditions therefrom Select a carrier wave.

For example, the physics of the signal quality of each carrier wave, interference size, load state, uplink and downlink link can be provided Selection gist of the source quantity (such as PDCCH (physical layer descending control channel)) as composition carrier wave.Specifically, to terminal and Speech, signal quality of the terminal on some carrier wave is high, small, the carrier wave the load of interference that is subject to is relatively low, it possesses The physical resource of uplink and downlink is more, then the carrier wave be chosen as composition carrier wave probability it is then relatively large.

The various factors of considerations above can have different priority or different weights.

In the case where setting the priority of various factors, made decisions based on the factor with higher priority.For example, Any sequence can be set to the physical resource quantity, interference size and load state of signal quality, uplink and downlink link Priority, that is to say, that set priority-based, can determine that candidate composition is carried based on any one of above-mentioned factor Wave.Alternatively, the factor can be arranged different priority groups, such as the physics of signal quality, uplink and downlink link provides The priority of source quantity is higher than the priority for interfering size and load state, or opposite priority orders, Huo Zheshe is arranged Set the different priority groups of the factor comprising different factor or different number.That is, based on priority group and excellent The setting of the priority orders of first grade group can be solely based on any group of because usually determining candidate composition carrier wave.

Inside each above-mentioned priority group, such as in signal quality and uplink and downlink link physical resource quantity structure At group in, can weight (can the identical or difference that depends on the circumstances) be set to various factors.

In the case where setting different weights to various factors, choosing of the various factors to composition carrier wave is exactly considered The influence selected.Depending on the needs of practical application, any weight distribution can be set.In general, can be with setting signal quality, uplink Weight with the physical resource quantity of downlink is higher than the weight for interfering size and load state.

In second of application scenarios, that is, second of available carrier wave coverage area distribution pattern, as shown in figure 3, respectively Base station 310,320,330 uses two kinds of carrier waves F3 and F4 respectively, and the coverage area of F4 is more than and basically comprises covering for F3 The corresponding cell principal security spreadability of lid range, wherein F4, the corresponding cells of F3 are mainly used for improving handling capacity.In this feelings Under condition, F3 and F4 are likely located in different carrier frequency bands, belong to noncontinuity carrier convergence.

Under the application scenarios, when terminal 250 is only in the coverage area of F4 without in the coverage area of F3, due to The problem of available carrier wave only has F4 mono-, therefore there is no carrier wave selections.When the covering in two kinds of carrier waves F3, F4 simultaneously of terminal 250 When within the scope of lid, that is, there is carrier wave select permeability.According to a kind of embodiment that the application proposes, in this case, if Other conditions are not considered, and the carrier wave i.e. F4 that coverage area can be selected larger are as new composition carrier wave.If covering model Enclosing larger carrier wave has multiple and coverage area essentially identical, then further further according to the selection strategy of the first scene Composition carrier wave is selected, this will be described in more detail below.

Certainly, it is similar to the first scene, a load can be therefrom selected in the case where further considering other conditions Wave.

For example, likewise, can be by the signal quality of each carrier wave, interference size, load state, uplink and downlink links Physical resource quantity (such as PDCCH) the also selection gist as composition carrier wave.Specifically, for terminal, the terminal is at certain Small, the carrier wave relatively low, its uplink and downlink possessed the objects of load of interference that signal quality on a carrier wave is high, is subject to Reason resource is more, then the carrier wave is chosen then relatively large for the probability of main composition carrier wave.

The various factors of considerations above can have different priority including the coverage area of each available carrier wave Or different weight.

In the case where setting the priority of various factors, made decisions based on the factor with higher priority.For example, It can be to available carrier wave coverage area, signal quality, the physical resource quantity of uplink and downlink link, interference size and load shape Condition sets the priority of any sequence, that is to say, that sets priority-based, can be based on any one of above-mentioned factor To determine candidate composition carrier wave.Alternatively, the factor can be arranged different priority groups, such as the priority of coverage area Higher than the priority of the physical resource quantity of signal quality, uplink and downlink link, signal quality, uplink and downlink link object Priority of the priority higher than interference size and load state of resource quantity is managed, or the priority orders that setting is opposite, or The different priority groups of factor of person's setting comprising different factor or different number.That is, being based on priority group With the setting of the priority orders of priority group, can be solely based on any group of because usually determining candidate composition carrier wave.

In the case where setting different weights to various factors, choosing of the various factors to composition carrier wave is exactly considered The influence selected.Depending on the needs of practical application, any weight distribution can be set.In general, the power of coverage area can be set Again be higher than signal quality, uplink and downlink link physical resource quantity weight, signal quality, uplink and downlink link object Manage weight of the weight higher than interference size and load state of resource quantity.

In the third application scenarios, that is, in the third available carrier wave coverage area distribution pattern, as shown in figure 4, respectively Base station 410,420,430 uses two kinds of carrier waves F5 and F6 respectively, the coverage areas of two available carrier waves substantially it is misaligned not yet Including but overlap each other, the corresponding cell principal security spreadabilities of wherein F5, the corresponding cells of F6 be mainly used for improve handles up Amount (or otherwise).The characteristics of this application scene, is the border land that the corresponding antenna in cell of F6 is directed toward in the corresponding cells of F5 Area, the in this way application scenarios can greatly improve the handling capacity in F5 cell edges area.In this case, F5 and F6 may In different carrier frequency bands, belong to noncontinuity carrier convergence.

Under the application scenarios, when terminal 250 only in the coverage area of F5 or only in the coverage area of F6 when, by The problem of there was only F5 or F6 mono- in available carrier wave, therefore being selected there is no carrier wave.When terminal 250 is simultaneously in two kinds of carrier waves In the coverage area of F5, F6, that is, when in the overlapping areas of two kinds of available carrier wave overlay areas, that is, there is carrier wave selection and ask Topic.

A kind of embodiment proposed according to the application in this case, can be at least if not considering other conditions Candidate composition carrier wave is determined according to terminal present position and its moving direction and rate travel.

In this application, it is contemplated to terminal location and its Three models of movement, as shown in Fig. 5 to Fig. 7.But it should Solution, the position of terminal and its movement can have other dividing modes, Three models here can also change, split or Merge.

The first pattern as shown in figure 5, terminal 250 at the edge of an available carrier wave F5 and just far from the available carrier wave. In this case, it if terminal is being rapidly directed away from the available carrier wave, assigns far from available carrier wave (this corresponding to direction In be exactly F6) the higher probability for becoming candidate composition carrier wave.It can certainly directly select far from the carrier wave corresponding to direction As candidate composition carrier wave, that is, the probability is 100%.If the available carrier wave corresponding to the separate direction has multiple (in addition to F6 also has other available carrier waves), then determined in this multiple available carrier wave according at least to the size of coverage area it is candidate at Part carrier wave, that is, similar to previously described the first or second of application scenarios.

Mentioned above " quick " is separate.Here, the meaning of " quick " refers to according to its speed, it is contemplated that terminal will take off quickly Carrier wave coverage area from current place, rather than just small-scale movement.For example, if terminal user is only in small range It inside walks about, he may be without departing from the intention of the reference carrier wave (such as go to another), if more new carrier wave at this moment Lead to unnecessary operation.In concrete application, " quick " is great speed actually, can specifically be set according to practical application It is fixed.

Fig. 6 illustrates another terminal location and motor pattern, that is, terminal 250 is located at the edge of a certain available carrier wave F5 And it is mobile inside towards available carrier wave F5.At this point, being determined according at least to the size of the coverage area of available carrier wave F5 and F6 Candidate composition carrier wave is similar to second of application scenarios.If coverage area is just identical, using under the first scene Selection strategy.

Fig. 7 illustrates another terminal location and motor pattern, that is, crossover area of the terminal 250 in available carrier wave F5 and F6 Position far from overlapping areas edge in domain, that is to say, that the inside in overlapping areas.At this point, also according at least to available carrier wave The size of F5, F6 coverage area determines candidate composition carrier wave, that is, is similar to second of application scenarios.If the lucky phase of coverage area Together, then the selection strategy under the first scene is applied.

Certainly, the first and second of application scenarios are similar to, can in the case where further considering other conditions from One carrier wave of middle selection.

For example, likewise, can be by the signal quality of each carrier wave, interference size, load state, uplink and downlink links Physical resource quantity (such as PDCCH) the also selection gist as composition carrier wave.These factors, including terminal present position and its Including moving direction and rate travel, the coverage area of each available carrier wave, can have different priority or different power Weight.

In the case where setting the priority of various factors, made decisions based on the factor with higher priority.For example, Can to terminal present position, terminal moving direction, terminal rate travel and available carrier wave coverage area, signal quality, on The physical resource quantity of row and downlink, interference size and load state set the priority of any sequence, that is to say, that base In the setting of priority, candidate composition carrier wave can be determined based on any one of above-mentioned factor.Alternatively, can be to described Different priority groups, such as terminal present position, terminal moving direction, terminal rate travel and available carrier wave is arranged in factor The priority of coverage area higher than signal quality, uplink and downlink link physical resource quantity priority, signal quality, on The priority of the physical resource quantity of row and downlink is opposite higher than the priority for interfering size and load state, or setting Priority orders, either setting comprising different factor or different number factor different priority groups.Namely It says, the setting of the priority orders based on priority group and priority group, can be solely based on any group of because usually determining Candidate composition carrier wave.

In the case where setting different weights to various factors, choosing of the various factors to composition carrier wave is exactly considered The influence selected.Depending on the needs of practical application, any weight distribution can be set.In general, can with setting terminal present position, The weight of terminal moving direction, terminal rate travel and available carrier wave coverage area is higher than signal quality, uplink and downlink chain The weight of the physical resource quantity on road, signal quality, uplink and downlink link physical resource quantity weight it is big higher than interference Small and load state weight.

Second embodiment

In the first embodiment, the selection of composition carrier wave is described for different application scenarios.Work as in practical application In, such as already described above, various application scenarios may be mixing.For example, both there may be complete for the coverage area of each available carrier wave Full weight folds (the first application scenarios), it is also possible to which there are inclusion relations (second of application scenarios) or part to be folded (third Kind application scenarios).

Therefore, as shown in figure 8, according to a kind of embodiment that the application proposes, successively with suitable for different application field The selection strategy of scape selects candidate composition carrier wave, candidate composition reference carrier wave is gradually reduced, until obtaining composition to be used Carrier wave.That is, on the basis of first embodiment, when the distribution of the coverage area of each available carrier wave includes at least two When preassigned pattern, first candidate composition carrier wave is determined according to the criterion corresponding to one of which pattern, then according still further to another pattern Corresponding criterion determines the second candidate composition carrier wave in the candidate composition carrier wave, is carried until obtaining unique candidate composition Wave.

Specifically, as shown in Figure 8, it is first determined the coverage area (step 102) for each available carrier wave that terminal can use. Then determine whether the distribution of the coverage area of each available carrier wave meets predetermined distribution pattern (step 104).The two steps exist It has had a detailed description in first embodiment, has been not repeated herein.

Determining that coverage area, can be with there are many in the case of distribution pattern such as first mode 806 and second mode 910 First candidate composition carrier wave (step 808) is determined according to the first criterion corresponding to first mode.For example, if before first mode is The third application scenarios is stated, then determines candidate composition carrier wave using the composition carrier wave selection strategy of the third application scenarios.Institute Determining candidate composition carrier wave may be unique, and flow terminates at this time, use identified candidate composition carrier wave.It is identified Candidate composition carrier wave is also possible to not unique.Such as under the third application scenarios, if having in the terminal direction of motion it is multiple can The factor considered with the factors of carrier wave and the other aspects of each available carrier wave or according to selection strategy is also roughly the same, then There may be multiple available carrier waves to can be used as candidate composition carrier wave.It is just needed at this time using the second criterion corresponding to second mode (such as selection strategy corresponding to the first or second of application scenarios) comes continuous in the multiple candidate composition carrier-current relaying (step 812) is selected, composition carrier wave to be used is obtained.

Fig. 8 illustrates only the case where two kinds of distribution patterns.Obviously, distribution pattern can have more kinds of, and each distributed mode The application order of the selection strategy of formula can be random.

Third embodiment

In addition, when terminal works are under carrier convergence pattern, in addition to a main composition carrier wave, there are one or multiple the It two composition carrier waves (SCC, Secondary Component Carrier) while working, these carrier waves are all in state of activation. Simultaneously still may there are one or multiple carrier waves be in configured but unactivated state, it is also possible to there are one or multiple carrier waves at In non-configuration status.

When needing to change main composition carrier wave, new main composition carrier wave can be selected from the second composition carrier wave used It selects, it can also be from not yet configuring or be configured but selected in still unactivated available carrier wave.When need add the second composition When carrier wave, the second new composition carrier wave can be selected from the available carrier wave not yet configured, can also be from being configured but not yet It is selected in the available carrier wave of activation.

Wherein, the purpose of end message acquiring unit 1202 is the information for the coverage area for obtaining the available carrier wave of terminal, So that distribution of carriers pattern determining unit determines available carrier wave coverage area distribution pattern.Available carrier wave coverage area information needs base It is determined in the parameter of the position of terminal and base station carrier.And terminal location can both have been measured by base station 1220 itself, it also can be by Terminal 1260 determines (process (1)) by means of such as GPS of global position system 940 (global positioning system).

Therefore, in the case of satellite positioning, end message acquiring unit 1202 can be obtained from terminal 1260 in terminal The location information (process (2)) for setting positioning device, to which the available carrier wave information acquisition terminal for being based further on base station is available The information of the coverage area of carrier wave.

In addition, in the case of base station location, since terminal location itself is obtained by base station, base station can be straight It connects and obtains available carrier wave coverage area information according to the position.

When distribution of carriers pattern determining unit 1204 judges the predetermined distribution pattern for the coverage area of each available carrier wave When essentially identical, each available carrier wave is used as candidate composition carrier wave by the composition carrier wave determination unit 1206.

Here, signal quality is the information that terminal itself conventionally can be obtained, other base stations, carrier wave or end End etc. is also the information that can be conventionally obtained by terminal based on signal quality to the interference of present terminal.As for uplink Then it is the information that can be grasped by base station itself based on traditional technology with the physical resource quantity and load state of downlink. When considering interference of the present terminal to other terminals, relevant information is also by information acquisition of the base station based on other terminal reports. Therefore, composition carrier wave determination unit 1206 obtains related information from terminal 1260 if necessary (see the process (5) in Figure 13)

The composition carrier wave determination unit 1206 can be further configured to：When determining candidate composition carrier wave, model is covered It encloses, terminal present position and its importance of moving direction and rate travel are higher than signal quality, the object of uplink and downlink link Manage resource quantity importance, signal quality, uplink and downlink link physical resource quantity importance higher than interference size With the importance of load state；Alternatively, coverage area, terminal present position and its moving direction and rate travel, signal quality, The physical resource quantity of uplink and downlink link, interference any one of size and load state either it is multiple individually or Jointly determine candidate composition carrier wave.

The update of composition carrier wave

8th embodiment

The respective embodiments described above describe how selection composition carrier wave, including main composition carrier wave and the second composition carrier wave.

And after having selected composition carrier wave, also to use flow appropriate from old main composition wave conversion to selected New main composition carrier wave, either add selected the second new composition carrier wave or with selected the second composition newly Carrier wave replaces a certain the second old composition carrier wave (being in fact the joint of addition action and deletion action).In addition, also needing appropriate Ground determines the opportunity of update or addition composition carrier wave.

Therefore, as shown in figure 15, in the present embodiment, it is proposed that one kind updated in carrier convergence communication network it is main at The method of part carrier wave, including：Obtain the status information (step 1502) of terminal, base station and/or main composition carrier wave；Determine the shape Whether state information conforms to a predetermined condition (step 1504)；It is replaced with new main composition carrier wave in the case where conforming to a predetermined condition old Main composition carrier wave (step 1506).

In the prior art, can have composition carrier wave in various parameter characterization terminals, base station and its use and The performance of workable carrier wave, state etc., and various measurements can be passed through or means of communication obtains relevant information.For this A little information can need to be arranged various predetermined conditions according to practical application, main composition is updated when meeting predetermined condition Carrier wave.

Enumerating and not restrictive as an illustrative example, the newer condition for carrying out main composition carrier wave considered can To include at least one of following conditions：

1. terminal is moved to outside the coverage area of old main composition carrier wave；

2. old main composition carrier signal quality declines；

3. the physical resource quantity of old main composition carrier wave uplink and downlink link is inadequate；

4. the considerations of the problems such as former base station is to network overall load balance and inter-user interference, requires to update main composition load Wave；

5. terminal is moved in the coverage area of new base station.

Switching flow may be used in the update of main composition carrier wave, can also use Reconfiguration Procedure.As shown in figure 16, it is cutting In change of current journey, old main composition carrier wave own base station sends " wireless heterogeneous networks " (RRC, Radio Resource to terminal Control) reconfiguration information, " wireless heterogeneous networks " reconfiguration information include mobile control information (MobilityControlInfo), the mobile control information includes the wireless resource configuration of new main composition carrier wave (RadioResourceConfig).Then the mobile control in " wireless heterogeneous networks " reconfiguration information described in terminal utilization is believed Breath reconfigures MAC (media access control), PDCP (Packet Data Convergence Protocol) and RLC (wireless spread-spectrum technology) layer, updates Security key, and configure new main composition carrier wave using the wireless resource configuration of the new main composition carrier wave.

Then initiating random access procedure accesses new main composition carrier wave.Random access procedure can be initiated by terminal, It can be initiated by base station.It is that terminal proposes access request, new main composition carrier wave own base station is according to money when being initiated by terminal The process that the access request situation of source and other terminals is distributed, is emulative, that is to say, that random access is each end Hold the process of preempting resources.When a random access is unsuccessful, the needs that depend on the circumstances retry, or need to reconfigure infinitely Resource allocation information, or need to switch again.When random access procedure is initiated by new main composition carrier wave own base station, base It is that terminal has reserved corresponding resource, therefore terminal gives response in advance to stand, except the case where nonterminal side occurs Variation.This random access is known as noncompetitive random access.

After random access to new main composition carrier wave, old main composition carrier wave can be deactivated.Deactivation can adopt In two ways.One is new main composition carrier wave own base stations directly to send deactivation command (as shown in figure 16) to terminal, Terminal deactivates old main composition carrier wave after receiving deactivation command.Another way is will be old using implicit deactivation mode Main composition carrier wave deactivate (Figure 16 is not shown), i.e., terminal need not receive deactivation command from base station, but voluntarily deactivate Old main composition carrier wave living.This auto-action can be completed based on timer, i.e., system has pre-defined old Main composition carrier wave deactivates live time, or has pre-defined the trigger condition of packet data inactivity timer.

It should be noted that described herein " new main composition carrier wave own base station " and " old main composition carrier wave " are affiliated Base station.When new old master's composition carrier wave belongs to same base station, what above-mentioned two term referred to is exactly same base station.

As previously mentioned, the update of main composition carrier wave can also use Reconfiguration Procedure.As shown in figure 18, with switching flow phase Than Reconfiguration Procedure can be without the process of random access procedure and more new key.In addition, the content of RRC reconfiguration informations It is simplified, do not include the mobile wireless resource configuration for controlling information and only including new main composition carrier wave.Therefore, terminal After receiving RRC reconfiguration informations only need new main composition carrier wave is configured, without reconfigure MAC, PDCP, Rlc layer and update security key, therefore the overhead brought due to updating main composition carrier wave can be reduced, it avoids more QoS of customer declines problem caused by new main composition carrier wave.At this point, it includes new master not needed in RRC information body All relevant configuration informations (such as not comprising mobile control information) of composition carrier wave, and only need include and former main composition carrier wave Compared to newer configuration information, that is, wireless resource configuration, increment signaling can be referred to as.

9th embodiment

Obviously, the update of all main composition carrier waves can be by the way of switching.But not all main composition Carrier wave updating can be by the way of reconfiguring.This is because only when new old master's composition carrier wave safety having the same is close Key and need not reset MAC, PDCP and rlc layer when, are possible to use Reconfiguration Procedure.

Therefore, the application continues to propose to determine newer flow according to newer scene, if update it is front and back it is main at Part carrier wave is subordinated to the same base station, then uses Reconfiguration Procedure to update main composition carrier wave.If the front and back main composition of update carries Wave is not belonging to the same base station, then uses switching flow to update main composition carrier wave.

Specifically, as shown in figure 17, the flow for updating main composition carrier wave includes：Determine new main composition carrier wave whether with Old main composition carrier wave belongs to same base station (step 1702)；If belonging to same base station, is used by the base station and reconfigure stream Journey replaces old main composition carrier wave (step 1704) with new main composition carrier wave；Otherwise from old main composition carrier wave own base station to New main composition carrier wave own base station sends switching request, and (step for information about is obtained from new main composition carrier wave own base station 1704), then switching flow is used to replace old main composition carrier wave (step 1706) with new main composition carrier wave.

Specifically, in step 1704, old main composition carrier wave own base station (hereinafter simply referred to as old base station) is to new Base station described in main composition carrier wave (hereinafter simply referred to as new base station) sends switching request, so as to new base station prepare terminal be switched to it is new Configuration information needed for main composition carrier wave, to which old base station can obtain required configuration information from new base station, so as to old base station Preparation will issue the RRC reconfiguration informations of terminal in switching flow.

Described in 1706 Figure 16 above in conjunction and Figure 18 of Reconfiguration Procedure 1704 and switching flow in the embodiment As Reconfiguration Procedure with switching flow is.Slightly different place is, due to new main composition carrier wave and old main composition Carrier wave is not belonging to same base station, thus while RRC reconfiguration informations are still to be sent by old base station, but after configuration Random access procedure is the interaction (being described made by combination Figure 31 as detailed below) between new base station.It completes to configure as terminal Response (or confirmation) message later, and directly issue new base station.

Compare the 8th embodiment and the 9th embodiment, due to during switching, need reset MAC, PDCP and Rlc layer, and update security key, thus will inevitably increase overhead and the phenomenon that communication disruption occur.And it uses When Reconfiguration Procedure, overhead will substantially reduce, and communication interruption time can also be reduced.Therefore, the 9th embodiment proposes It whether is subordinated to same base station according to the front and back main composition carrier wave of update and decides whether using switching flow or reconfigure stream The mode of the main composition carrier waves of Cheng Gengxin can reduce the overhead brought due to updating main composition carrier wave, avoid updating The problems such as QoS of customer caused by main composition carrier wave declines.

In above-mentioned Reconfiguration Procedure, new main composition carrier wave generally should also be located at identical with old main composition carrier wave Frequency range, Timing Advance having the same and all synchronous with base station holding.If being unsatisfactory for such condition, such as Figure 19 It is shown, before deactivating old main composition carrier wave, also to initiate the random access to new main composition carrier wave.

Tenth embodiment

In the 8th and the 9th embodiment, implicit premise is that new main composition carrier wave has been initially configured and has swashed It is living.But in practical application, there is also new main composition carrier wave not yet initial configurations, though it has been initially configured still The scene not being activated.

In such a scenario, undoubtedly the carrier wave for the not yet initial configuration that work done in the manner of a certain author is new principal component carrier wave is carried out initial It configures and activates, to initial configuration but still unactivated carrier wave that work done in the manner of a certain author is new principal component carrier wave into line activating.Initially match (not shown) should be carried out at the very start in switching flow or Reconfiguration Procedure by setting (i.e. the addition of the carrier wave), but be swashed It is relatively more flexible in time sequencing to live through journey.As corresponding to Figure 16,18,19 Figure 20-22 shown in, activation can with Completion is set either after random access procedure or old main composition carrier wave deactivates and (sends out deactivation as shown in the figure for base station Order, but as it was noted above, deactivation process can also be terminal itself implicitly deactivation) before, activation life is sent out by base station It enables.Alternatively, as corresponding to Figure 16,18,19 Figure 23-25 shown in, activation can also send out RRC reconfiguration informations it It is preceding that activation command is sent by base station.

In addition activation command can with other Command combinations or send simultaneously.For example, if new main composition carrier wave is The state of non-initial configuration then by initial configuration and can will activate the two processes to merge, and defining one, new " configuration swashs Work " process is completed at the same time configuration and activation, i.e. base station sends out " allocation activation " order, and terminal is once completed to match after receiving the order It sets and activates.In addition, activation command can also simultaneously be sent with " wireless heterogeneous networks " reconfiguration information.

In another embodiment, initial configuration flow and switching flow later or Reconfiguration Procedure can close And carried out included in an order, without separating.That is initial configuration commands can be with RRC reconfiguration informations Merge.

11st embodiment

The update of second composition carrier wave is described below.As previously mentioned, for the update of the second composition carrier wave, including addition institute The second new composition carrier wave of selection, or replace a certain the second old composition to carry with selected the second new composition carrier wave Wave.Latter situation is in fact the joint of addition action and deletion action.The considerations of similar to eight embodiments, in order to proper Locality determines that the opportunity of update or addition composition carrier wave, present embodiment propose a kind of side of the second composition carrier wave of update Method.

As shown in figure 26, the method for present embodiment includes：Obtain the state of terminal, base station and/or the second composition carrier wave Information (step 2202)；Determine whether the status information conforms to a predetermined condition (step 2204)；In the feelings to conform to a predetermined condition The second new composition carrier wave is added under condition or replaces the second old composition carrier wave (step 2206) with the second new composition carrier wave.

In the prior art, can have composition carrier wave in various parameter characterization terminals, base station and its use and The performance of workable carrier wave, state etc., and various measurements can be passed through or means of communication obtains relevant information.For this A little information can need to be arranged various predetermined conditions according to practical application, when meeting predetermined condition update second at Part carrier wave.

Enumerating and not restrictive as an illustrative example, the newer condition of carry out the second composition carrier wave considered May include at least one of following conditions：

1. since business needs, more second composition carrier waves are needed；

2. terminal is moved to outside the coverage area of the second old composition carrier wave；

3. the second old composition carrier signal quality declines；

4. the physical resource quantity of the second old composition carrier wave uplink and downlink link is inadequate；

5. the considerations of the problems such as former base station is to network overall load balance and inter-user interference, requires the second composition of update Carrier wave；

6. terminal is moved in the coverage area of new base station.

The update of second composition carrier wave uses Reconfiguration Procedure.The Reconfiguration Procedure in conjunction with described in Figure 18 for it is main at The Reconfiguration Procedure of part carrier wave is similar.The differ in that since second composition carrier wave does not have a uniqueness, the second one-tenth The newer essence of sub-carrier is the second new composition carrier wave of addition as previously described, therefore used in second composition carrier wave updating Reconfiguration Procedure need not include deactivation process.

Specifically, in Reconfiguration Procedure, base station sends " wireless heterogeneous networks " (RRC, Radio to terminal Resource Control) reconfiguration information, " wireless heterogeneous networks " reconfiguration information only includes that the second new composition carries The wireless resource configuration (RadioResourceConfig) of wave.Then terminal utilizes the nothing of the new main composition carrier wave Line resource allocation information configures the second new composition carrier wave.Due to being not necessarily to reconfigure MAC, PDCP and rlc layer and update peace Full key, therefore the overhead brought due to the second composition carrier wave updating can be reduced, it avoids bringing user service matter Measure decline problem.At this point, not needing to include all relevant configuration informations of the second new composition carrier wave in RRC information body (such as controlling information not comprising mobile), and only need comprising the wireless resource configuration with the second composition carrier wave, it can To be referred to as increment signaling.

Similarly, it is similar to the tenth embodiment, in practical application, there is also the second new composition carrier waves not yet just Begin configuration, though it has been initially configured the scene being not yet activated.

Similarly, activation command can with other Command combinations or send simultaneously.For example, activation command can be with institute It states " wireless heterogeneous networks " reconfiguration information while sending.

12nd embodiment

The method of update composition carrier wave described in 8th to the tenth embodiment is assisted by base station and terminal in a communications system With progress.

Therefore, in the present embodiment, it is proposed that be able to realize the terminal of aforementioned various embodiments, base station and lead to Letter system.

In present embodiment and follow-up each embodiment in the description of terminal, base station and communication system, unless necessary, It is not repeated to describe the details that aforementioned each embodiment has been described in, and can be found in the description of aforementioned each embodiment.

As shown in figure 29, the base station 2420 in a kind of carrier convergence communication network is communicated with terminal 2520, completes main composition The update of carrier wave.Specifically, which includes：State acquiring unit 2402 obtains terminal, base station and/or main composition carrier wave Status information；Status determining unit 2404, determines whether the status information conforms to a predetermined condition；And main composition carrier wave is more New unit 2406, old main composition carrier wave is replaced in the case where conforming to a predetermined condition with new main composition carrier wave.

Specifically, state acquiring unit 2402 is to determine whether to meet master according to this to obtain status determining unit 2404 The information of composition carrier wave updating condition.Need to obtain which information depends on the update condition, and update condition be can root Carry out arbitrary setting according to specific application.

For example, the predetermined condition includes at least one of following conditions：

2. old main composition carrier signal quality declines；

5. terminal is moved in the coverage area of new base station.

So, for the 1st and the 5th condition, it is necessary to which the main composition carrier wave based on terminal location and corresponding base station covers Lid range is judged.For the 2nd condition, need to obtain signal quality information from terminal.For the 3rd condition, need from Base station obtains for information about.4th condition is entirely then the order from base station.

Therefore, depend on the predetermined condition specifically why, state acquiring unit 2402 may only need to be obtained from base station itself It takes for information about without being interacted with terminal 2520, it is also possible to which needs are interacted with terminal 2520 and obtained for information about.As for The specific acquisition modes of information, have been described in the description of the selection previously for composition carrier wave, no longer heavy herein It is multiple.

Main composition carrier wave updating unit 2406 interacts and completes the update of main composition carrier wave with terminal 2502.Such as institute above It states, all main composition carrier wave updatings can be completed by switching flow.Therefore, in a kind of embodiment, such as scheme Shown in 30, the main composition carrier wave updating unit 2406 may include：Reconfiguration information transmission unit 24062 is sent to terminal " wireless heterogeneous networks " reconfiguration information, " wireless heterogeneous networks " reconfiguration information include mobile control information, the shifting Dynamic control information includes the information for reconfiguring MAC, PDCP and rlc layer, update security key by terminal, and by terminal For configuring the wireless resource configuration of new main composition carrier wave；And random access unit 24064, it is non-competing for initiating Property random access makes response to the random access request of terminal.

As it was noted above, switching flow includes the deactivation to old main composition carrier wave, but can both be sent out by base station Activation command can also implicitly be deactivated by terminal itself.When using former mode, the main composition carrier wave updating unit 2406 can also include deactivation command transmission unit 24066, for deactivating old main composition carrier wave, as shown in figure 30. But when using latter approach, the main composition carrier wave updating unit 2406 can not include deactivation command transmission unit 24066。

Corresponding to this, present embodiment additionally provides corresponding terminal 2520, as shown in figure 30 comprising：Re-match confidence Receiving unit 2502 is ceased, for receiving " wireless heterogeneous networks " reconfiguration information from base station；Mobile control dispensing unit 2504, is used MAC, PDCP and rlc layer are reconfigured in " wireless heterogeneous networks " reconfiguration information according to, updates the letter of security key Breath；Radio-resource-configuration unit 2506, for wirelessly being provided included in " wireless heterogeneous networks " reconfiguration information according to Source configuration information configures new main composition carrier wave；Random access unit 2510, for initiating competitive random access or right The noncompetitive random access that base station is initiated makes response；And unit 2508 is deactivated, for according to presetting or root Old main composition carrier wave is deactivated according to the deactivation command that base station is sent.

Above-mentioned base station 2420 and terminal 2520 are suitble to complete the switching flow.When completion reconfigures stream as previously described Cheng Shi, naturally, " wireless heterogeneous networks " that the reconfiguration information transmission unit 24062 is configured as sending to terminal reconfigure Information only includes the wireless resource configuration of the new main composition carrier wave, for configuring new main composition by terminal 2520 Carrier wave.Correspondingly, the function of mobile control dispensing unit 2504 is not needed in terminal 2520.
