Description
Technical field
The present invention relates to the communications field, particularly a kind of implementation method of DRX function and device.
Background technology
In LTE (Long Term Evolution) agreement, stipulate, can be UE configuration DRX (discontinuous reception) function that is in " RRC_CONNECTED " (radio resource control connection) state, after opening the DRX function, UE can discontinuous monitoring PDCCH (physical down shared control channel).A DRX cycle is made up of two states: " operating state "---and UE monitors PDCCH during this period; " DRX state "---UE can skip the Data Receiving of PDCCH to save electric weight during this period.
In order to realize in the DRX cycle transformation between two states, network side rrc layer at the DRX functional configuration of each UE several timers, be called the relevant timer of DRX, be example with a UE, the relevant timer of DRX mainly comprises:
DRX Inactivity Timer: the i.e. inactive timer of DRX, be expressed as UE receive the scheduling new data the PDCCH signaling after, allow the number of the PDCCH subframe of monitoring continuously, in such cases, after having monitored the PDCCH that sets number, DRX Inactivity Timer is overtime, and UE has just satisfied a condition that enters the DRX state;
On Duration Timer: promptly continue timer, be expressed as UE when DRX cycle begins, allow the number of the PDCCH subframe of monitoring continuously, in such cases, after having monitored the PDCCH that sets number, On Duration Timer is overtime, and UE has just satisfied a condition that enters the DRX state;
DRX Retransmission Timer: i.e. DRX retransmission timer, generally, in a subframe, be provided with 8 HARQ (Hybrid Automatic Repeat Request at UE, mix automatic repeat requests) process, except that seeding, a DRX Retransmission of each descending HARQ process configuration Timer, when each DRX Retransmission Timer all is expressed as UE expectation re-transmission, need the number of the PDCCH subframe of monitoring continuously, in such cases, monitored the PDCCH of setting number at any one DRX Retransmission Timer after, corresponding D RX Retransmission Timer is overtime: UE has just satisfied a condition that enters the DRX state;
HARQ Rtt Timer: i.e. HARQ loopback timer, generally, in a subframe, be provided with 8 HARQ processes at UE, except that seeding, a HARQ Rtt of each descending HARQ process configuration Timer, each HARQ Rtt Timer all is expressed as UE and waits for the minimum number of subframes that receives the HARQ re-transmission, in such cases, receive on the subframe of number after HARQ retransmits setting at any one HARQ Rtt Timer, corresponding HARQ Rtt Timer is overtime, and UE has just satisfied a condition that enters the DRX state.
The UE lateral root is according to the DRX configuration parameter, each DRX of maintenance and operation timer of being correlated with, and whether enter the DRX state according to the state decision of the relevant timer of DRX, determine whether to monitor PDCCH then, and carry out corresponding data transmit-receive process.Network side (eNB) is then according to the DRX state operation dispatching of UE, and carry out corresponding data transmit-receive, be that network side needs regularly the relevant timer of DRX of UE to be safeguarded and upgraded, and when whether the condition of the part of the relevant timer defined of the DRX that regularly judges UE/all start DRX function was met, for example, whether 4 kinds of DRX that judge UE timer of being correlated with was all overtime, if, then network side is no longer dispatched this UE, otherwise, this UE of network side normal consistency.
Under the prior art, network side is each UE in the system in each subframe, upgrade the state of the relevant timer of its DRX, after update all finishes, current state according to the relevant timer of DRX confirms whether each UE can enter the DRX state, if then the DRX effective marker position with UE is effective, otherwise, be invalid with the DRX effective marker position of UE.Then, before each scheduling, network side if flag bit is effectively, is not then dispatched this UE at the state that MAC checks the DRX effective marker position of UE; If flag bit is invalid, this UE of normal consistency then; At last, in finishing scheduling and when receiving the scheduling feedback of UE, need to upgrade DRX Inactivity Timer, DRX Retransmission Timer and the HARQ Rtt Timer of this UE, for example, if dispatched the new biography (up/descending) of UE, then start or restart DRX Inactivity Timer; If of having dispatched UE is descending, then starts corresponding HARQ Rtt Timer, and stop corresponding DRX Retransmission Timer; If the HARQ Rtt Timer that is fed back to NACK and correspondence that receives is overtime, then start corresponding DRX Retransmission Timer.
This shows, present DRX realization mechanism, be in each subframe, all to upgrade the relevant timer of corresponding D RX for intrasystem all UE by network side, and network and in when scheduling, all UE in might not the single system of dispatching out, but optionally UE is dispatched by dispatching algorithm.Therefore network side is in each subframe, might not need to judge the DRX flag bit of all UE, and the DRX flag bit that only need obtain the UE that accepts scheduling gets final product, from this view point, network side is that all UE upgrade the relevant timer of corresponding D RX in the system in each subframe, is a kind of waste to system time frequency resource.
For example, suppose to have in the sub-district 1000 UE, each UE need dispose 1 DRX Inactivity Timer, 1 On Duration Timer, 8 DRX Retransmission Timer and 8 HARQ Rtt Timer: then in the sub-district to I haven't seen you for ages the relevant timer of configuration 1000* (1+1+8+8)=18000 DRX, the precision all very high (is granularity with 1ms) of the relevant timer of each DRX, so, network side all carries out the state renewal to the relevant timer of these 18000 DRX in each subframe, this brings huge resource overhead will for the processor of network side, thereby influence cell capacity, be specially: if it is constant to keep cell capacity, just need more high performance processor, or, a plurality of processor concurrent workings, this will improve the equipment cost of network side greatly, if keep hardware environment constant, just need to reduce UE number in the sub-district, reduce power system capacity.

Embodiment
In order not improve equipment cost, do not influence under the prerequisite of cell capacity, reduce the operation expense of system, in the embodiment of the invention, when realizing the DRX function, by the following technical solutions: before preparing scheduling, network side need be checked the state of the relevant timer of DRX of this UE to be scheduled, and judges according to the state of the relevant timer of DRX whether UE to be scheduled enters the DRX state, if, then do not dispatch, otherwise, normally dispatch; Wherein, but network side does not carry out any operation for existing this UE that is not scheduled in the system.Promptly be meant, when each scheduling, network side no longer judges at each UE whether it enters the DRX state, but only judge at UE to be scheduled whether it enters the DRX state, this UE that does not dispatch is not done any operation, like this, can significantly reduce the operation expense of network side, also can not increase the equipment cost of network side.
Further, in the embodiment of the invention, network side can not be that all UE in the system upgrade the relevant timer of corresponding D RX (4 kinds are all upgraded) in each millisecond yet, but adopt the mode of upgrading at particular point in time, on time shaft, UE is staggered, be dispersed in each different time point as far as possible, on each time point, upgrade the relevant timer of DRX of all UE of this time point correspondence, like this, can further reduce the operation expense of system, and equally no longer increase the equipment cost of network side.
In finishing scheduling with when receiving the scheduling feedback of UE, network side also needs according to the result of scheduling and receives situation about feeding back, upgrade DRX Inactivity Timer, the DRX Retransmission Timer of corresponding UE and the state of the relevant timer of these several middle DRX of HARQ Rtt Timer, for not having scheduling or not receiving that the relevant timer of DRX of the UE of feedback does not then carry out any operation.
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.
Consult illustrated in figures 1 and 2ly, in the embodiment of the invention, be provided with several base stations at network side, and have some UE in end side, the base station comprises dispensing unit 20 and scheduling unit 21, wherein,
Dispensing unit 20 is used for when UE inserts, and the UE at each access sets up the relevant timer of corresponding D RX respectively, and the relevant timer of this DRX enters the required satisfied condition of DRX state in order to limit UE;
Scheduling unit 21, be used in scheduling process, adopt default dispatching algorithm to determine at least one UE to be scheduled in the current subframe, and judge according to the state of the relevant timer of the DRX of this at least one UE correspondence whether this at least one UE enters the DRX state, if, then this at least one UE is not dispatched, otherwise, this at least one UE is carried out normal consistency.
Based on technique scheme, consult shown in Figure 3ly, in the embodiment of the invention, be example with a base station and a UE, it is as follows to be presented in the general introduction flow process that realizes the DRX function in the LTE system:
Step 300: when the base station defined UE access LTE system, the UE at each access set up relevant timer of corresponding D RX and DRX monitor timer respectively, and wherein, the relevant timer of DRX enters the required satisfied condition of DRX state in order to limit UE.
In the embodiment of the invention, the base station is that the relevant timer of DRX that UE sets up promptly is DRX Inactivity Timer, On Duration Timer, DRX Retransmission Timer and HARQ Rtt Timer.
And the UE that the relevant timer of above-mentioned each DRX is limited enter the DRX state condition can for: the relevant timer of above 4 kinds of DRX is all overtime.
In running, base station side need be maintained as the relevant timer of DRX that each UE sets up, and when part/full terms that the relevant timer of the DRX of a certain UE is limited triggers, and the DRX flag bit of this UE is labeled as effectively.
Step 310: in scheduling process, adopt default dispatching algorithm to determine at least one UE to be scheduled in the current subframe, and judge according to the state of the relevant timer of the DRX of described at least one UE correspondence whether this at least one UE enters the DRX state, if, then this at least one UE is not dispatched, otherwise, this at least one UE is carried out normal consistency.
In the present embodiment, in each subframe, the base station is before scheduling UE, need all to judge whether UE to be scheduled has entered the DRX state, be specially: the base station needs to judge according to the state of the relevant timer of DRX of UE correspondence to be scheduled whether the DRX flag bit of UE to be scheduled is effectively, if illustrate that then UE need enter the DRX state, otherwise, illustrate that UE need not to enter the DRX state.
Adopt technique scheme, before dispatch UE in each subframe the base station, need not to judge whether all UE enter the DRX state in the system, and only need obtain the DRX flag bit of UE to be scheduled, judge whether it enters the DRX state and get final product, significantly reduce the data volume of judgment processing, effectively reduced system's operation expense, avoided resource waste.
On the other hand, in step 310, if the base station determines that according to the state of the relevant timer of DRX of at least one UE correspondence this at least one UE enters the DRX state, then, the relevant timer of DRX of this at least one UE correspondence is restarted or start-up operation to this at least one UE finishing scheduling or receive scheduling when feedback of UE.For example, if dispatched the new biography (up/descending) of UE, then start or restart DRX Inactivity Timer; If of having dispatched UE is descending, then starts corresponding HARQ Rtt Timer, and stop corresponding DRX Retransmission Timer; If the HARQ Rtt Timer that is fed back to NACK and correspondence that receives is overtime, then start corresponding DRX Retransmission Timer.
Based on the foregoing description, in the prior art, in each subframe, the base station all needs the relevant timer of DRX of all UE is upgraded.In the embodiment of the invention, operation expense for further minimizing system, change the update mode of the relevant timer of DRX into Event triggered by Time Triggered, be specially: when the UE connecting system, in the process of setting up the relevant timer of corresponding D RX at each UE, set up a DRX monitor timer at each UE respectively, this DRX monitor timer is used to safeguard effective duration of the relevant timer of DRX of corresponding UE, when the DRX monitor timer is overtime, the base station needs the relevant timer of DRX to the UE of this DRX monitor timer monitoring to upgrade (can 4 kinds all upgrade, also can upgrade a part wherein); Wherein, the relevant timer of DRX is upgraded, be meant promptly for each UE start-up time of writing down in the relevant timer of each DRX according to UE and current time judge whether the relevant timer of each DRX is overtime respectively, and the relevant timer of DRX that will be overtime is changed to disarmed state.After relevant timer upgrades to DRX, corresponding D RX monitor timer need be restarted, thereby continue the relevant timer of DRX of corresponding UE is monitored, like this, the DRX monitor timer is determined some update time one by one of the relevant timer of corresponding DRX by safeguarding a section effective duration on time shaft.
In the practical application, generally, the relevant timer of DRX writes down some start-up time with the form of frame number and subframe numbers, and when needing judge whether the user enters the DRX state, judges with the interval of putting start-up time whether the relevant timer of DRX is overtime by current point in time at every turn.Owing to can overturn after frame number arrives 1024 (promptly again since 0), comprise 10 subframes in the frame, the duration of a subframe is 1ms, therefore, when characterizing the time by frame number and subframe numbers, can only represent 10240ms at most, so, if UE does not obtain scheduling (surpassing 10240ms) for a long time, then can cause adopting current frame number and subframe numbers, and start frame number and subframe numbers and judge that the judged result of the state of the relevant timer of DRX makes mistakes, therefore, when the DRX monitor timer being set at any one UE, preferable, effective duration that this DRX monitor timer is safeguarded can not surpass 1024 frames, promptly can not surpass 10240ms, as, effective duration of can the DRX monitor timer safeguarding is set to 2560ms.
Further, concentrate when overtime for fear of the relevant timer of the DRX of each UE, the lot of data Processing tasks brings impact for the processor of base station, preferable, point start-up time of the DRX monitor timer of each UE is set to evenly distribute on time shaft, promptly setting up in the process of corresponding D RX monitor at each UE respectively, whenever, set up a DRX monitor timer, the start-up time point that this DRX monitor timer is set and some start-up time of the DRX monitor timer of the last foundation setting duration of being separated by, as, 1ms.For example, consult shown in Figure 4, in the embodiment of the invention, when setting up the DRX monitor timer at each UE respectively, put selecting of on time shaft, increasing progressively successively the start-up time of each DRX monitor timer, as shown in Figure 4, time period with 10240ms is an example, DRX monitor timer for first UE, click its start-up time and be selected as 0ms, and some update time of the relevant timer of the represented DRX of effective duration of its maintenance is: 0ms-＞2560ms-＞5120ms-＞7680ms, and for the DRX monitor timer of second UE, click its start-up time and be selected as 1ms, and some update time of the represented relevant timer of DRX of effective duration of its maintenance is: 1ms-＞2561ms-＞5121ms-＞7681ms, ... by that analogy, maximum is 2559-＞5119-＞7679-＞10239.1000 UE are arranged in the supposing the system, so, after adopting such scheme, the base station gets final product with regard to only needing the relevant timer of DRX to a UE to upgrade in a subframe, with respect to the scheme that in each subframe, will upgrade the relevant timer of the DRX of all UE under the prior art, the scheme that adopts the embodiment of the invention to provide, though need certain processing time during the state of judgement DRX monitor timer, but the maintenance workload of the relevant timer of DRX becomes original 1/1000, greatly reduce the processing complexity of system, further alleviate the operating load of system, saved system resource.Certainly, if have a large amount of UE in the system, then also may there be a plurality of DRX monitor timers overtime (still can not be intrasystem whole UE) simultaneously on the point in some update times, at this moment, the base station only needs in the manner described above respectively the relevant timer of DRX to each UE to upgrade operation respectively to get final product, do not repeat them here.
With a concrete execution mode technique scheme is elaborated below.Consulting shown in Figure 5ly, in the embodiment of the invention, is example with a UE, introduces the base station and realize that at UE the detailed process of DRX function is as follows in system:
During step 400:UE connecting system, the relevant timer of corresponding D RX is set up at this UE in the base station, further, has also set up the DRX monitor timer.
Then, relevant timer of base station initiated each DRX and DRX monitor timer, and in UE keeps in communication the process that is connected with network side, safeguard relevant timer of DRX and DRX monitor timer.
Step 410: in current subframe, judge whether the DRX monitor timer of UE is overtime, if, then carry out step 420, otherwise, carry out step 430.
Step 420: the relevant timer of DRX to UE carries out the state renewal, then, carry out step 430.
Step 430: determine UE in current subframe when waiting to dispatch UE, before scheduling, confirm the state of the relevant timer of DRX of UE.
Step 440: according to the state of the relevant timer of the DRX of UE, judge whether UE enters the DRX state, if, then UE is not dispatched, carry out step 470; Otherwise, carry out step 450.
Step 450: UE is dispatched, distribute corresponding running time-frequency resource.
Step 460: the relevant timer of part or all of DRX that upgrades UE.
Be specially: after to the UE finishing scheduling or receive scheduling when feedback of UE, the relevant timer of part or all of DRX of UE is carried out again or start-up operation.For example, if dispatched the new biography (up/descending) of UE, then start or restart DRX Inactivity Timer; If of having dispatched UE is descending, then starts corresponding HARQ Rtt Timer, and stop corresponding DRX Retransmission Timer; If it is overtime that the scheduling that receives is fed back to the HARQ Rtt Timer of NACK and correspondence, then start corresponding DRX Retransmission Timer.
Step 470: enter next subframe, return step 410.
In sum, in the embodiment of the invention, the base station is when the UE connecting system, set up the relevant timer of DRX at UE, and before dispatching, only the state according to the relevant timer of the DRX of current UE to be scheduled determines whether UE is dispatched in current subframe, rather than the state of the relevant timer of the DRX that confirms all UE, like this, can save the operation expense of network side effectively, avoided the wasting of resources of system, and the user capacity that also can not increase the equipment cost of network side and influence the sub-district; Further, the base station is when the UE connecting system, can also set up DRX monitor timer in order to effective duration of safeguarding the relevant timer of DRX, like this, just the update mode with the relevant timer of DRX is changed into by Event triggered by Time Triggered, only when the DRX of a certain UE monitor timer is overtime, just the relevant timer of corresponding D RX being carried out state upgrades, rather than in each subframe, all the relevant timer of the DRX of all UE is carried out state and upgrade, like this, just further save the operation expense of system, avoided the wasting of resources of system, and the user capacity that can not increase the equipment cost of network side and influence the sub-district equally.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
