Description
Technical field
The present invention relates to reserved resource processing method in the mobile communication system, particularly preset resource active method in the 3-G (Generation Three mobile communication system).
Background technology
In today of personal communication fast development, the market demand has greatly promoted the progress of mobile communication technology.3-G (Generation Three mobile communication system) (3rd Generation, be called for short " 3G ") particularly, each standards system all has the enhancement techniques that improves systematic function separately.Wherein resource reservation is exactly a kind of enhancement techniques, by reserve air-link resources during communication switching, communicates so that activate once more, saves the expense of connecting time.At Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, be called for short " WCDMA ") or TD SDMA (Time Division Synchronous CodeDivision Multiple Access, abbreviation " TD-SCDMA ") in the 3G communication system, according to third generation partner program (3rd Generation Partnership Project, abbreviation " 3GPP ") suggestion of technical specification TR 25.879, all adopt the technology of resource reservation, provided detailed preset resource active mode.
Because in mobile communication system, base-station node (Node Base Station is called for short " NodeB ") will receive a plurality of users' access, offers user's Radio Link separately.On the ordinary meaning, each access of each user all needs network side system to carry out access process one time, and this process relates to a plurality of functional modules, not only expends system resource, and needs certain processing delay.Therefore, resource reservation is exactly a kind ofly to activate to make in needs and be used for accelerating the method that user's access procedure and saving system pay wages by reserving existing resources.Such as, system is after the service that finishes certain user, do not discharge the air-link resources that offers this user, but all are comprised that interface-free resources, line resource etc. all reserve, promptly be in the state that does not have the user to use but do not discharge, and when having the user to insert again, system has judged whether that just reserved resource can activate use.Activate reserved resource and can improve access efficiency greatly directly for new user's use, accelerate turn-on time, improve system effectiveness.
The mechanism of resource reservation and activation can reduce time delay that signaling continues, reduce the interference of air interface.In this course, subscriber equipment (User Equipment, be called for short " UE ") mutual with NodeB by air interface, network side is by radio network controller (Radio Network Controller, abbreviation " RNC ") a plurality of NodeB of control carry out radio communication and route, service wireless network controller (Services RNC wherein, abbreviation " SRNC ") management of responsible reserved resource, the transport channel synchronization process and the Radio Link of striding NodeB and RNC interface (IUB mouth) or RNC interface (IUR mouth) activate.If there is floating radio network controller (Drift RNC in network, be called for short " DRNC "), then the transport channel synchronization between SRNC and the NodeB is to stride the IUR mouth alternately, and relevant transmission channel synchronization frame is issued DRNC by IUR, is issued to NodeB by DRNC by IUB again; If there is no DRNC, relevant transmission channel synchronization frame directly is issued to NodeB by IUB.
In activation, SRNC will send the Radio Link activation command to NodeB by IUB mouth or IUR mouth, the notice reserved resource inserts UE and serves, because characteristic difference and the environment difference of each UE, the wireless parameter configuration of each wireless access is different, when therefore activating reserved resource, SRNC also needs to relate to the modification of reserved resource being carried out wireless parameter, and it can normally be communicated by letter with UE after activation.
If reserved resource relates to the modification of relevant wireless parameter, to carry out Radio Link again and activate, whole process is with regard to more complicated.The Radio Link activation command is the stability that guarantees that number passes less than response, and SRNC will consider after the NodeB wireless parameter comes into force, and issues data again and gives UE.How not judge that reserved resource finished the criterion of wireless parameter configuration owing to provide SRNC in the existing 3G architectural framework, therefore SRNC need activate the wireless parameter that relates to Radio Link and make some predictions in the entry-into-force time at NodeB place, so that learning that radio link parameter has successfully been revised by NodeB finishes, issue data again.Consider the shake of IUB chain of command in the practical application, IUR chain of command; and the shake on the NodeB processing delay; the wireless parameter entry-into-force time is uncertain; cause SRNC prediction wireless parameter difficult at the time ratio that NodeB comes into force; this not only can hide because the uncertain insecure hidden danger of bringing of communication mechanism; and at first guarantee the length that the SRNC guard time is enough in the ordinary course of things; guarantee that radio link parameter enters into force, thereby the time that causes activating the reserved resource process is longer.
As seen, current 3G system can't guarantee the reliability of preset resource active mechanism, also may cause activationary time to surpass under opposite extreme situations and rebulid the Radio Link required time, and this will deviate from the original intention of this technology of resource reservation.Therefore, how improving the preset resource active method of 3G mobile communication system, make active mode reliable, and can shorten the activation processing delay as far as possible, to reach the purpose of real raising system effectiveness, is one of key issue of current 3G mobile communication technology research.
In the NodeB reserved resource, its time-delay state of activation information element (Delayed Activation IE) is non-activation (Deactivate), but still the transmission channel synchronization frame that can normal response SRNC issues.Therefore SRNC can carry out the poll of transport channel synchronization periodically, issues transmission channel synchronization frame, and expectation NodeB provides response.If NodeB does not provide response, SRNC can think that data surface is unusual, and reserved resource can't use, and this moment, SRNC may select to delete reserved resource, all was available to guarantee present NodeB reserved resource.
Description according to 3GPP R5 standard, the activation of reserved resource has some IEs relevant with UE, for example Frame Offset (vertical shift), in the prior protocols framework, can make amendment, also can revise some IE in addition by the Radio Link activation command by asynchronous the reshuffling of Radio Link.When reserved resource was activated, network side will be revised these IE earlier, activates then.Network side issues on reserved resource in the data, need to guarantee NodeB successful Application IE, carry out transport channel synchronization then, issue data.
Under the existing 3G network framework, have the situation of two kinds of preset resource actives, a kind of is the method that has the radio link parameter modification process separately; Another does not then need to carry out separately the method for radio link parameter modification process, radio link parameter is revised comprehensively activated in the message at Radio Link in the method.
But existing method all can not guarantee the certainty and the reliability that come into force behind the reserved resource parameter modification, and specifically, these methods are to wait for the regular hour by SRNC intelligently, so that guarantee that reserved resource enters into force generally speaking.
Fig. 1 shows the preset resource active method flow process that has the radio link parameter modification process of prior art scheme.As shown in the figure, the first step is used reserved resource when the SRNC decision, and SRNC issues the related news that radio link parameter is revised, and carries out the modification of radio link parameter; In second step, after NodeB modification radio link parameter finishes, respond the SRNC response message; The 3rd step, SRNC is after receiving this response message, issue the Radio Link activation command, carrying Delayed Activation IE is Activate, notice NodeB opens downlink (Start Rx), carry the relevant IE of other Radio Links, begin to prepare to use this Radio Link (Radio Link is called for short " RL "); In the 4th step, SRNC issues transport channel synchronization and gives NodeB, carries out transport channel synchronization at new link; In the 5th step, NodeB responds the transport channel synchronization response; In the 6th step, SRNC waits for and to think that the data of NodeB have revised finish (Start Tx) behind the certain hour, begins to issue data and give NodeB.
According to engineering experience, can estimate the time delay of each step in the above-mentioned flow process.In existing framework, SRNC need wait for that NodeB sends out the response message about the modification radio link parameter of meeting, can confirm that parameter modification finishes, and SRNC begins to issue data then.If wherein the time delay of first step to the second step needs the success of 80ms ability, SRNC must wait for 80ms so, could begin to issue data and give NodeB.If step 1 to 2 80ms consuming time, NodeB internal modification wireless parameter 60ms consuming time when activating in the 3rd step, the 4th step and the 5th step 60ms consuming time, the overall delay of whole flow process is at least at 200ms.And more fatal be, SRNC does not know when NodeB internal modification parameter can come into force, must reserve time enough, therefore the time of SRNC additional wait makes the 3rd to go on foot not only 60ms of reality, may arrive more than the 120ms, just become 260ms from beginning to activate reserved resource to the overall time delay that can send data like this.
Fig. 2 shows the preset resource active method flow process that does not have the radio link parameter modification process of prior art scheme.As shown in the figure, the first step, when reserved resource is used in the SRNC decision, issue the Radio Link activation command, carrying Delayed Activation IE is Activate, and notice NodeB opens downlink, carry the relevant IE of other Radio Links, begin to prepare to use this RL, NodeB receives message, begins to revise described Radio Link and activates the radio link parameter that will revise in the message; In second step, SRNC issues transport channel synchronization and gives NodeB, carries out transport channel synchronization at new link; In the 3rd step, NodeB responds the transport channel synchronization response; In the 4th step, SRNC waits for that the NodeB parameter modification finishes, and begins to issue data then and gives NodeB.
Same carries out the time delay estimation according to engineering experience, compare with last a kind of situation, lacked independent radio link parameter modification process, but SRNC issues before the data, still needing to guarantee to activate the IE that carries in the message enters into force, but in the prior protocols framework, can't learn definitely when NodeB revises parameter and finish, can only wait for that the sufficiently long time guarantees works fine generally speaking by SRNC.Consider the be correlated with modification of IE of NodeB inside, can send data, need the above processing delay of 160ms from beginning to be activated to.
In the process of above-mentioned preset resource active, SRNC can't judge whether IE comes into force in NodeB.In actual applications, it is very crucial that IE comes into force for link communication, there is not the application of frame skew (Frame Offset) of success such as NodeB, SRNC has just issued data, be connected frame number (Connection Frame Number what the situation of soft handover may cause descending merging data that UE receives on the data of receiving on the new link and the link that falling, be called for short " CFN ") inconsistent, thus cause merging mistake; And in the situation of direct-cut operation, may cause at new link suddenly because the change of FrameOffset and obliterated data.Therefore make SRNC must guarantee that IE comes into force and waits for time enough at NodeB.
In actual applications, there is following problem in such scheme: because SRNC can't know whether IE comes into force at NodeB for sure, whether radio link parameter is revised and finished among the NodeB, and when activating, must finish guaranteeing that NodeB revises, thereby make that activating time delay increases by waiting for the sufficiently long time.Yet this machine-processed root problem is to know that reserved resource is available, has the fail safe hidden danger of communication all the time.In the practical application, in order to accelerate the activation of reserved resource, SRNC wishes just can issue data in the process of revising the NodeB parameter, but whether finish and to guarantee owing to activate the resource parameters modification, so SRNC often postpones data in moment that new link issues by expection, this mode is not only accurate inadequately but also very consuming time, can't make full use of and activate resource and set up and finish and shorten the advantage of link setup time, the signaling time delay that may cause in the time of serious adopting the active link mode has deviated from the original intention of preset resource active mechanism fully greater than the signaling time delay of selecting additionally newly to set up successful link.
Cause the main cause of this situation to be, do not provide SRNC in the prior art scheme and guarantee that IE comes into force, the radio link parameter of NodeB is revised the mechanism that finishes in NodeB, there is security reliability hidden danger in communication, and can bring extra processing delay to guarantee this method that Radio Link comes into force by SRNC prediction and wait, reduce system effectiveness, strengthen processing delay.

Embodiment
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.
Core concept of the present invention is to introduce the special mechanism of judging when reserved resource comes into force, allow SRNC pass through an existing or newly-increased message from NodeB, learn the moment that reserved resource is activated and comes into force, and guarantee that SRNC safety on the resource that activates issues data.Thus, guarantee Radio Resource can with after shorten processing delay as far as possible, utilize the short advantage of connecting time that reserved resource brings more fully.This method is not only reliable, and can improve system effectiveness.
Specifically, the present invention is by increasing NodeB notice SRNC reserved resource available this mechanism that enters into force in activation process, make SRNC can in time know among the NodeB radio link parameter revise finish, reserved resource can use.Wherein, NodeB is used to notify the message of SRNC after the parameter modification of the Radio Link that is activated comes into force fully, can be multiplexing existing message, also can be a newly-increased message.
The present invention provides a plurality of embodiment, uses different modes to realize this mechanism respectively, all can reach goal of the invention.Such as adopting transmission channel synchronous control frame scheme, promptly by transport channel synchronization control frame notice, at first introduce new criterion in the data surface transport channel synchronization, NodeB responds by transport channel synchronization and to inform SRNC after the parameter modification of activated wireless link comes into force fully.Perhaps adopt the signaling plane prioritization scheme, realize by signaling plane optimization, introduce new criterion at signaling plane, NodeB informs RNC by reporting particular message after the parameter modification of activated wireless link comes into force fully.Also can adopt activation parameter inquiry control frame scheme, realize by activation parameter inquiry control frame, introduce new mechanism at data surface, RNC is after issuing the Radio Link activation command, constantly issue query argument and revise the control frame that comes into force, NodeB after the parameter modification of activated wireless link comes into force fully, by parameter modification come into force the response control frame inform RNC.
In one embodiment of the invention, by transport channel synchronization control frame scheme for SRNC provide to reserved resource can with, revise the criterion that radio link parameter comes into force.As previously mentioned, in the prior art scheme, SRNC adopts the method for cycle polling NodeB reserved resource, and whether effective, promptly periodically send the transport channel synchronization control frame if detecting reserved resource, return response by NodeB.In fact, owing to when not having the user to use, not necessarily must carry out the transport channel synchronization process, only need between the Radio Link active period, carry out transport channel synchronization in the NodeB reserved resource.Therefore promptly transport channel synchronization is finished the criterion that Radio Resource activates as NodeB in one embodiment of the present of invention, help to reduce the signaling time delay, can realize this reserved resource criterion on the basis of existing technology easily.So just need to revise the response mechanism of NodeB for the transport channel synchronization control frame, make and when cycle polling at ordinary times, do not do response, only after the activation and finish radio link parameter revise make reserved resource can with situation under just do response, thereby make SRNC can judge in view of the above that reserved resource enters into force.
Adopt transmission channel synchronous control frame scheme in one embodiment of the invention, in the NodeB reserved resource, when its Delayed Activation IE is the Deactivate type, response transmission channel synchronization frame not.SRNC is setting up Radio Link simultaneously, and its Delayed Activation IE is the Deactivate type, and behind the transfer resource of associated transport layer, does not carry out transport channel synchronization, does not also open the transport channel synchronization poll in cycle at ordinary times.In this case, SRNC does not need reserved resource is carried out also can not judging synchronously whether reserved resource is also effective, do not delete reserved resource when not activating reserved resource.And NodeB responds the transport channel synchronization response frame, and need possess following condition simultaneously: the Delayed Activation IE of Radio Link is the Activate type, and the expression reserved resource is activated; The wireless parameter that will revise that carries in the Radio Link activation command enters into force; There is not ongoing radio link parameter modification process in NodeB inside.After above-mentioned condition all possessed, NodeB just responded transport channel synchronization control frame response, promptly notify the SRNC reserved resource can with and radio link parameter revise and come into force, the communication can guaranteed is normally carried out.SRNC starts the Radio Link activation process, after carrying out the air-link resources modification, begin to carry out the transport channel synchronization process, if received the response of transmission channel synchronization frame, just thinking that the relevant radio resource parameter of NodeB has been revised finishes, begin on the activated wireless link to send out data immediately, with the shortening time delay that continues.
As previously mentioned; because when SRNC activates reserved resource; may have independent wireless parameter modification process; also may not have independent wireless parameter modification process; as the activation process of Fig. 1 and Fig. 2, whether the system that considers again protects DRNC respectively, will influence the path of SRNC to the signaling flow warp of NodeB; if comprised DRNC signaling can be earlier through the IUR mouth to DRNC then through the IUB mouth to NodeB, vice versa.Therefore in one embodiment of the invention, comprise four kinds of schemes that realize described transport channel synchronization control frame: promptly with independent wireless parameter modification process, but SRNC is only by IUB mouth and the mutual situation of NodeB; With independent wireless parameter modification process, but SRNC is by IUR mouth and IUB and the mutual situation of NodeB; Not with independent wireless parameter modification process, but SRNC is only by IUB mouth and the mutual situation of NodeB; Not with independent wireless parameter modification process, but SRNC is by IUR mouth and IUB and the mutual situation of NodeB.
Fig. 3 shows the independent wireless parameter modification process of band according to an embodiment of the invention but SRNC only passes through under the mutual situation of IUB mouth and NodeB the preset resource active method flow process of transmission channel synchronous control frame scheme.
As shown in Figure 3, in step 301, use reserved resource when the SRNC decision, SRNC issues the related news that radio link parameter is revised, and carries out the modification of radio link parameter.NodeB begins to carry out the modification of radio link parameter after receiving that radio link parameter is revised order.
Then in step 302, SRNC does not wait for the response message that radio link parameter is revised, the parallel Radio Link activation command that issues, carrying Delayed Activation IE is the Activate type, carry other IEs relevant with Radio Link, notice NodeB opens downlink, begins to prepare to use this RL.
Then in step 303, SRNC issues the transport channel synchronization control frame and gives NodeB, carries out transport channel synchronization at new link.
Then in step 304, NodeB responds the transport channel synchronization response frame, need possess following condition simultaneously: the Delayed Activation IE of Radio Link is that the wireless parameter that will revise that carries in Activate, the Radio Link activation command enters into force and there is not ongoing radio link parameter modification process in NodeB inside.These processes are triggered by step 301.After above-mentioned condition all possessed, NodeB began to respond transport channel synchronization, activated by transport channel synchronization response frame notice SRNC reserved resource.
Then in step 305, if SRNC has received the transport channel synchronization response frame, just to think that the Radio Link relevant parameter of NodeB has been revised to finish, reserved resource has switched and has finished, and SRNC just begins to issue data and give NodeB this moment.
In step 306, NodeB also can return radio link parameter at last and revise the message of finishing, but this message has not had reference significance for SRNC, and in step 304, SRNC has obtained the criterion that radio link parameter comes into force.
As seen, adopt above-mentioned transmission channel synchronization frame scheme after, NodeB revises and promptly to respond the SRNC response message after radio link parameter finishes, SRNC just can issue data, the shortening processing delay.With the contrast of aforementioned prior art scheme, the time delay of step 301 to 302 needs 80ms, issue because the Radio Link activation command is parallel, and SRNC does not need the response of waiting step 301, and then the time delay of step 301 may be reduced to 70ms.Therefore the time delay that overall time delay is a step 301 adds the time delay=130ms of step 304, and SRNC need not expect that Radio Link activates the modification time that IE is carried in the message the inside, has reduced 130ms than the 260ms time delay of prior art scheme.
Fig. 4 shows the independent wireless parameter modification process of band according to an embodiment of the invention but SRNC passes through under the mutual situation of IUR mouth and IUB mouth and NodeB the preset resource active method flow process of transmission channel synchronous control frame scheme.This scheme and scheme shown in Figure 3 contrast as seen from the figure, different places are that signaling all needs to transmit through DRNC for NodeB under each SRNC, and same NodeB is uploaded to SRNC also needs DRNC to transmit.In like manner, in the time delay contrast, obviously lack a lot than existing technical scheme.
Fig. 5 show according to an embodiment of the invention not with independent wireless parameter modification process but SRNC only by under the mutual situation of IUB mouth and NodeB, the preset resource active method flow process of transmission channel synchronous control frame scheme.
As shown in the figure, in step 501, when reserved resource is used in the SRNC decision, SRNC issues the Radio Link activation command, and carrying Delayed Activation IE is the Activate type, carries the relevant IE of other Radio Links, notice NodeB opens downlink, begins to prepare to use this RL.
Then in step 502, SRNC issues transmission channel synchronization frame and gives NodeB, carries out transport channel synchronization at new link.
Then in step 503, NodeB responds the transport channel synchronization response frame, need possess following condition simultaneously: the Delayed Activation IE of Radio Link is the Activate type, the parameter modification that relates in the Radio Link activation command enters into force, and there is not ongoing radio link parameter modification process in NodeB inside.After above-mentioned condition all possessed, NodeB began to respond transport channel synchronization, activated by transport channel synchronization response frame notice SRNC reserved resource.
Then in step 504, if SRNC has received the transport channel synchronization response frame, just to think that the Radio Link relevant parameter of NodeB has been revised to finish, reserved resource has switched and has finished, and SRNC just begins to issue data and give NodeB this moment.
As seen, compare with the prior art scheme, NodeB inside is carried out the relevant IE of Radio Link to be modified to the time delay actual value of finishing is 60ms in the step 501, step 502 is 60ms to step 503, because these steps walk abreast, therefore overall time delay minimum may reach 60ms, and SRNC need not expect that Radio Link activates the modification time that IE is carried in the message the inside, has saved 100ms than the 160ms of prior art scheme.
Fig. 6 show according to an embodiment of the invention not with independent wireless parameter modification process but SRNC by under the mutual situation of IUR mouth and IUB mouth and NodeB, the preset resource active method flow process of transmission channel synchronous control frame scheme.This scheme and scheme shown in Figure 5 contrast as seen from the figure, different places are that signaling all needs to transmit through DRNC for NodeB under each SRNC, and same NodeB is uploaded to SRNC also needs DRNC to transmit.In like manner, in the time delay contrast, obviously lack a lot than existing technical scheme.
In another embodiment of the present invention, adopt the signaling plane prioritization scheme, increase the activation of dedicated signaling: a NodeB notice SRNC Radio Link at signaling plane and finish signaling message, be used for NodeB after finishing the parameter modification that the Radio Link activation command carries IE, response SRNC Radio Link activation command is finished message, and notice SRNC preset resource active parameter modification comes into force available.SRNC finishes message to this wireless links activation and finishes the criterion that the Radio Resource activation command carries the IE parameter modification as NodeB.Equally, NodeB responds Radio Link and activates and finish message and need possess following condition simultaneously: the Delayed Activation IE of Radio Link is the Activate type, and the expression reserved resource is activated; The wireless parameter that will revise that carries in the Radio Link activation command enters into force; There is not ongoing radio link parameter modification process in NodeB inside.After above-mentioned condition all possessed, NodeB just responded Radio Link and activates and to finish message, promptly notify the SRNC reserved resource can with and radio link parameter revise and come into force, the communication can guaranteed is normally carried out.SRNC starts the Radio Link activation process, issuing the Radio Link activation command carries out after air-link resources revises, finish message if received the Radio Link activation, just thinking that the relevant radio resource parameter of NodeB has been revised finishes, begin on the activated wireless link, to send out down data immediately, with the shortening time delay that continues.
