Abstract
The invention discloses a dynamic configuration method for E-PUCH (Enhance-Physical Uplink Channel) resources, comprising the following steps of: sending midamble configuration information of all time slots to UE (User equipment) of HSUPA (High Speed Uplink Packet Access) by an RNC (Radio Network Controller) during establishment of HSUPA scheduling service, wherein all the time slots in a cell are probably turned into the E-PUCH resources; and carrying out dynamic configuration on the E-PUCH resources by only adopting a physical share reconfiguration request when the dynamic configuration is carried out on the time slot in which the E-PUCH resources are located. Thus, midamble configurations of all the time slots are uniformly issued to the UE already during service establishment, no extra radio bearer reconfiguration process is needed to be introduced to inform the UE to perform corresponding midamble configuration after the E-PUCH resources are reconfigured, thereby the signaling interaction between the UE and a network during the dynamic configuration is avoided, and the influence on a user rate during reconfiguration is avoided.
Description
Technical field
The present invention relates to the resource allocation method in the communication system, particularly a kind of Dynamic Configuration of E-PUCH resource.
Background technology
In the existing communication system, introduce HSUPA and be used to improve higher uplink bit rate.
The UE of scheduling method HSUPA uploads data if desired, need to send the MAC-e entity requests resource of SI to NodeB by E-RUCCH or E-PUCH, the MAC-e entity is given UE according to the suitable E-PUCH resource (comprising time slot, code channel and duration) of resource allocation of current E-PUCH state of resources and UE application, issue mandate (AG) by the E-AGCH channel and give UE, UE parses time point, time slot and the code channel that sends data after receiving and authorizing.Further, UE need obtain the Midamble configuration of the E-PUCH resource place time slot that is assigned with when sending data, carries out data and sends.Wherein, the Midamble of E-PUCH resource place time slot configuration be by RNC in loading establishing process, reshuffle in the idle message E-PUCH Info field by radio bearer and carry to UE's.
At present in the TD-SCDMA system, time slot that can dynamic-configuration E-PUCH resource place when on the HSUPA frequency, having scheduling HSUPA user, for example, E-PUCH resource originally is time slot 2 and time slot 3, adjusts the back and is time slot 3 and time slot 4 (time slot configuration is 4: 2).
When carrying out the reprovision of E-PUCH resource place time slot, on the one hand by RNC with reprovision after the gap information at E-PUCH resource place be configured to NodeB, on the other hand, if behind the reprovision, there is online dispatched users on the E-PUCH resource of this reprovision, the midamble configuration of E-PUCH resource place time slot behind the reprovision need be sent to the on-line scheduling user.
The mode of carrying out the time slot dynamic-configuration of E-PUCH resource at present has two kinds.
The realization flow of first kind of mode as shown in Figure 1.Under first kind of implementation, carry out the E-PUCH resource of reprovision for needs, system at first moves out the user on this E-PUCH resource place frequency from this frequency, make the E-PUCH resource of this reprovision not carry Any user, then, carry out the reprovision of this E-PUCH resource place time slot again.
Particularly, at first, by step 101 among Fig. 1～102, Serving RNC (SRNC) utilizes Radio Link to set up process (Radio Link Setup Request/Response) and set up new air-link resources on other frequency, prepares to be used to carry the user who moves out on the reprovision E-PUCH resource frequency;
Then, by the step 103 among Fig. 1, S-RNC sets up the Iub transmission bearer by the ALCAP process;
Afterwards, by the step 104-105 among Fig. 1, S-RNC informs the air-link resources that the UE network side is redistributed by radio bearer reconfiguration course (RadioBearerReconfiguation), and the working frequency points of upgrading UE is to other frequencies; Radio Link on the reprovision E-PUCH resource frequency is deleted by Radio Link delete procedure (Radio Link Deletion Requst/Response) at step 106-107 again.
So far, finish moving out of user on the frequency, next by the step 108-109 among Fig. 1, control RNC (C-RNC) utilizes Physical Shared Channel reconfiguration course (Physical Share Channel Reonfiguration Request/Response) to adjust the time slot at corresponding E-PUCH resource place.Because the user on this frequency moves out, therefore reprovision has taken place not need to reinform this E-PUCH resource place time slot of user.
The flow process of second kind of implementation as shown in Figure 2.Under second kind of implementation, carry out the E-PUCH resource of reprovision for needs, no longer the user on this E-PUCH resource place frequency is moved out from this frequency, but directly carry out the time slot reprovision of E-PUCH resource, after finishing reprovision, new gap information is notified to the user on this frequency again.
Particularly, at first by step 201-202, C-RNC adjusts the E-PUCH resource of sub-district by Physical Shared Channel reconfiguration course (Physical Share Channel Reonfiguration Request/Response).
Then, by step 203-204, S-RNC utilizes radio bearer reconfiguration course (PhysicalChannel Reconfiguation) to inform HSUPA UE online on the corresponding frequency, the time slot configuration of the E-PUCH resource that network side reconfigures, thus guarantee that UE can carry out normal business and upload.
Wherein, in the radio bearer reconfiguration course, newly dispose E-PUCH resource gap information by field E-PUCH Info (see Table 1, select from 3GPP 25.331) configuration on-line scheduling HSUPA user.
In above-mentioned first kind of implementation,, need to introduce extra radio bearer reconfiguration course for carrying out on-line scheduling user's frequency migration; In second kind of implementation,, also need to introduce extra radio bearer reconfiguration course for the new time slot configuration information of notice on-line scheduling user.These radio bearer reconfiguration courses can increase the Signalling exchange between UE and the network, and have further taken the resource of UTRAN system.In second kind of implementation, UE is after receiving radio bearer reconfiguration message, and the process that can reconfigure physical resource itself also can influence user's speed at reconfiguration course.
Summary of the invention
In view of this, the invention provides a kind of Dynamic Configuration of E-PUCH resource, can avoid the Signalling exchange between the UE and network in the dynamic-configuration process, and avoid the influence of reconfiguration course user rate.
For achieving the above object, the present invention adopts following technical scheme:
A kind of Dynamic Configuration of E-PUCH resource comprises:
For arbitrary HSUPA UE, set up in the process in scheduling HSUPA business, for all time slots that may become the E-PUCH resource in the sub-district, RNC sends to described UE with the midamble configuration information of described all time slots;
When the E-PUCH resource of described HSUPA UE being carried out place dynamic time gap configuration, RNC carries out the dynamic-configuration of described E-PUCH resource by the Physical Shared Channel reconfiguration course.
Preferably, described RNC sends to described UE with the midamble configuration information of described all time slots and is:
The E-PUCH Info field of utilizing radio bearer to set up in the message is carried described midamble configuration information.
Preferably, after RNC carried out the dynamic-configuration of described E-PUCH resource by the Physical Shared Channel reconfiguration course, described UE was when carrying out transmitting uplink data, and this method further comprises:
UE determines time slot and the frequency of scheduling to the E-PUCH resource place of this UE according to the schedule information of NodeB;
Described UE determines the midamble configuration information of described scheduling to the E-PUCH resource place time slot of this UE from the midamble configuration information of described all time slots of RNC transmission, carry out transmitting uplink data.
As seen from the above technical solution, among the present invention, set up in the process in scheduling HSUPA business, for all time slots that may become the E-PUCH resource in the sub-district, RNC sends to HSUPA UE with the midamble configuration information of described all time slots; When carrying out the dynamic time gap configuration of E-PUCH resource place, only utilize physics to share the dynamic-configuration that reconfiguration course carries out the E-PUCH resource.Like this, because the midamble of each time slot configuration is the unified UE that is handed down to when business is set up, therefore, after carrying out E-PUCH resource reprovision, just do not need additionally to introduce again the radio bearer reconfiguration course, the corresponding midamble of notice UE configuration, thus the Signalling exchange between the UE and network in the dynamic-configuration process avoided, and avoid the influence of reconfiguration course to user rate.

Embodiment
For making purpose of the present invention, technological means and advantage clearer, the present invention is described in further details below in conjunction with accompanying drawing.
As previously mentioned, after the E-PUCH resource place time slot to certain frequency carries out reprovision,,, need to notify the gap information of E-PUCH resource behind the UE reprovision then for making these UE can normally carry out data upload if still have on-line scheduling HSUPA UE on this frequency.Particularly, as shown in table 1, this gap information comprises the time slot configuration of E-PUCH resource, the time-gap number at E-PUCH resource place, the midamble skew and the burst type of E-PUCH resource place time slot.
Carry out the process of transmitting uplink data in conjunction with HSUPA UE, can find above-mentioned gap information analysis, in scheduling process, NodeB can issue the E-PUCH resource of scheduling to UE, comprise the time-gap number at place and frequency numbering etc., but do not comprise the midamble skew of place time slot, therefore, behind the time slot reprovision of E-PUCH resource place, RNC sends in the gap information of UE by the radio bearer reconfiguration course, only the midamble of E-PUCH resource place time slot skew is that UE can't obtain by other modes, and other UE such as E-PUCH resource place time-gap number can obtain by the scheduling process of NodeB.
Simultaneously, the Midamble of sub-district time slot is configured in the life cycle of sub-district and can change, and the only corresponding a kind of Midamble configuration of each time slot.
Based on above-mentioned analysis, basic thought of the present invention is: in advance UE is issued in the midamble of each related time-slot configuration, when carrying out E-PUCH resource reprovision, do not need to send gap information behind the reprovision to UE again, thereby avoid the Signalling exchange between RNC and UE, simplify the processing of UE side.
Particularly, E-PUCH resource reconfiguration method flow of the present invention comprises as shown in Figure 3:
The mode of concrete transmission information can for: when scheduling HSUPA business is set up, utilize radio bearer reconfiguration course (Radio Bearer Setup) to set up the Radio Link of uploading of UE business, and on the E-PUCH Info field in Radio Bearer Setup message shown in Figure 3, carry the midamble configuration information of all possible E-PUCH resource place, this sub-district time slot.Specifically in Serving cell, which time slot may become E-PUCH resource place time slot, is those skilled in the art's known technology, just repeats no more here.
The E-PUCH Info field of UE from Radio Bearer Setup message extracted corresponding midamble configuration information, and is stored in the global variable.
What need here to further specify is, the radio bearer reconfiguration course in this step is meant that the radio bearer when business is set up sets up, and this process is the processing that must carry out before any HSUPA of carrying out business, is not the signaling process process of extra adding.The invention reside in the midamble configuration information that in this process, further carries related time-slot (promptly might becoming the time slot of E-PUCH resource in this sub-district).
By this step, RNC gives NodeB with new E-PUCH resource place time slot configuration.The realization of this step is identical with existing implementation, just repeats no more here.
After carrying out the operation of this step, the dynamic-configuration process of E-PUCH resource just is through with.After this, if carry out on the frequency of E-PUCH resource reprovision, UE need carry out transmitting uplink data, then on the one hand NodeB dispatches E-PUCH resource behind reprovision for it, UE preserves the midamble configuration of each possible E-PUCH time slot in step 301 on the other hand, can dispatch to E-PUCH resource place time slot behind the reprovision of this UE according to NodeB, and according to the midamble configuration information of preserving, determine the midamble configuration of the E-PUCH time slot of this scheduling, so just can carry out transmitting uplink data.
By as seen above-mentioned, E-PUCH resource dynamic collocation method among the present invention, when setting up, business further issues the midamble configuration of time slot to UE, and when carrying out the configuration of E-PUCH resource dynamic, just do not need to carry out the Signalling exchange of radio bearer reconfiguration course, thereby significantly reduced the Signalling exchange of E-PUCH resource dynamic configuration, simultaneously, because this dynamic-configuration process, directly on UE, do not carry out the reprovision of corresponding time slot information, therefore avoid the influence of reconfiguration course yet user rate.
Being preferred embodiment of the present invention only below, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
