Description
Technical field
The present invention relates to communication technical field, be specifically related to a kind of acquisition method of terminal disconnection and terminal, base station.
Background technology
Communication system deposits a lot of base station and the conforming problem of SOT state of termination.In general communication system, the state of terminal is divided into connected state and disconnected state.If base station access by terminal network, the scheduling authorization of base station can be monitored, be then in line states, be referred to as connected state.Otherwise terminal disconnection, is in disconnected state.The terminal being in disconnected state must access base station network again, and scheduling of resource and transfer of data normally could be carried out to it in base station.
The reason of terminal disconnection is a lot, and such as, terminal detects descending signal to noise ratio, if long-time lower than certain thresholding, then judge descending failure, causes terminal self to exit connected state, terminal disconnection.Or terminal uplink sends data, if there occurs wireless chain control layer (RadioLinkControl, be called for short RLC) the maximum retransmit of HARQ (AutomaticRepeatreQuest, be called for short ARQ), then terminal also can initiatively go offline.
But, if terminal does not temporarily send upstream data and arrives, and base station side finds the ARQ maximum retransmit of descending rlc layer and initiatively discharges terminal, and terminal does not receive Connection Release order, then cause the state of base station and terminal maintenance inconsistent, base station side discharges all information of terminal completely, but terminal is also thought at connected state.If so terminal initiates uplink scheduling request, base station can not respond.And base station also can not the downlink transfer of this terminal of active schedule.This is equivalent to terminal and hangs dead in a network for a long time.
Do not have uplink service in end side, and when base station side has discharged this end message, base station and terminal do not have service interaction, terminal is difficult to know that whether self is online.
In prior art, the monitoring method of terminal disconnection is: make terminal to report dispatch request (ScheduleRequest is called for short SR) information to base station, for asking uplink scheduling, if do not receive the scheduling authorization of base station, can report SR continuously.So arrange a maximum dispatch request SR to report number of times for the conservation treatment preventing base station side from having discharged end message; if terminal has uplink service to trigger report SR; still do not obtain the scheduling of base station after arriving maximum times, then think that terminal goes offline, concurrent is accessed again.
But in actual conditions, if there is a fairly large number of terminal in network, so terminal probably produces larger dispatch delay because system resource is limited.And cause in order to avoid dispatch delay SR to report not meet with a response and be mistaken for terminal disconnection, number of times is reported by maximum dispatch request SR to arrange so general longer, what cause terminal to find self to go offline so on the contrary is chronic, may be in base station and the inconsistent state of terminal for a long time.And the maximum dispatch request SR of simple increasing reports number of times fundamentally can not solve the problem of terminal disconnection erroneous judgement, because be difficult to dispatch delay maximum in Prediction System.
Known by description above, need the acquisition method that a kind of terminal disconnection is provided, make terminal when the Connection Release order not receiving base station, the situation that goes offline of self can be known quickly, the terminal disconnection erroneous judgement caused due to dispatch delay can be avoided again simultaneously.

Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, clear, complete description is carried out to the technical scheme in the embodiment of the present invention, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 shows the flow chart of the monitoring method of the terminal disconnection that the embodiment of the present invention one provides, and as shown in Figure 1, the monitoring method of the terminal disconnection of the present embodiment is as described below.
Step 101: in terminal and base station reciprocal process, terminal sends dispatch request SR to described base station.
Step 102: if terminal sends SR continuously number of times to described base station is N, terminal does not receive the SR response mandate that described base station sends, then determine that this terminal and described base station disconnect;
The response message for described base station sends to this terminal after receiving the SR of M this terminal transmission is authorized in described SR response, M<N.
In a preferred embodiment of the monitoring method gone offline of the present invention, the monitoring method of described terminal disconnection also comprises: if the number of times that terminal sends SR to described base station is less than N, terminal receives the SR response mandate that described base station sends, then terminal continues to send SR to described base station, and restarts the number of times that computing terminal sends SR;
If terminal sends SR continuously number of times to described base station is N again, terminal does not receive the SR response mandate that described base station sends, then determine that this terminal and described base station disconnect;
If terminal receives the uplink scheduling authorization that described base station sends, then terminal stops sending SR to described base station, will send the number of times clear 0 of SR.
In another preferred embodiment of the monitoring method of terminal disconnection of the present invention, the monitoring method of described terminal disconnection also comprises:
If the number of times that terminal sends SR continuously to described base station is less than N, terminal receives the SR response mandate that described base station sends, then terminal suspends one section of duration is t
0time period after, continue to send SR to described base station, and restart the number of times that computing terminal sends SR;
If terminal sends SR continuously number of times to described base station is N again, terminal does not receive the SR response mandate that described base station sends, then determine that this terminal and described base station disconnect.
Do not reduce terminal judges go offline speed prerequisite under, in order to reduce further SR respond mandate issue frequency, saving resource expense.Can report often taking turns SR--SR response is inserted the SR of a period of time between authorizing and is reported intermittent phase t
0.If i.e. terminal to report SR, have received corresponding SR authorization response, then have reason to think that terminal is also online, and base station knows and have recorded the situation that terminal has uplink traffic transmission demand.So a SR can be started report intermittent timer, interval a period of time, if also do not receive uplink scheduling authorization during this, more then continue to report SR.Because base station side is also aware of terminal uplink transmission demand, so also dispatch delay can not be caused because SR reports interval.
In the embodiment and two preferred embodiments of preceding method, the response message of the not enough or dispatch delay of the base station resource issued to terminal for described base station is authorized in described SR response.
In the embodiment and two preferred embodiments of preceding method, described N is preferably the multiple of M.
M time just response is on the one hand in order to reduce the expense that SR response is authorized for base station selection, and another aspect avoids the inspection of a SR void namely to trigger a secondary response.Considering that SR response is authorized again may error of transmission cause terminal to receive, so preferably N is the multiple of M, is equivalent to terminal and does not all receive the N/M of base station response, just think and go offline.
Thus, the monitoring method of the present embodiment and the terminal disconnection described in preferred embodiment thereof, utilize and SR Baos the detection feedback mechanism of – SR authorization response, the SR maximum wait response times N of setting terminal and base station must issue condition that SR response authorizes (must issue SR response mandate after receiving the SR request that M a certain terminal send).Therefore, when terminal has uplink service to arrive, SR dispatch request is sent continuously to base station.If terminal have sent N SR (N>M) continuously to base station, the SR response also do not received from base station is authorized, then think and self go offline.The monitoring method of the terminal disconnection described in the present embodiment can by arranging less N value, and Timeliness coverage self goes offline situation.
Certainly, during terminal sends N SR continuously, terminal receives the uplink scheduling authorization from base station, then terminal starts transfer of data, and nature can judge self not go offline.
The flow chart of the method that the transmission response that Fig. 2 shows the embodiment of the present invention two to be provided is authorized, as shown in Figure 2, the method that the transmission response of the present embodiment is authorized is as described below.
Step 201: in terminal and base station reciprocal process, base station receives the dispatch request SR that described terminal sends.
Step 202: if base station receives the SR of M described terminal transmission, then base station sends SR response mandate to this terminal; As long as base station receives a SR from described terminal, if base station can send uplink scheduling authorization to terminal, then preferentially send uplink scheduling authorization, and will SR the number clear 0 of described terminal transmission be received.
Send in a preferred embodiment of response authorization method of the present invention, the described method sending response mandate also comprises:
The SR of M described terminal transmission is received in base station, and to this terminal send SR response authorize after, if base station receives the SR that described terminal sends again, then restart to calculate and receive the number of times that this terminal sends SR, when again receiving the SR of M described terminal transmission, base station sends SR response to this terminal and authorizes.
Send in another preferred embodiment of response authorization method of the present invention, the described method sending response mandate also comprises:
When sending SR response mandate in base station to described terminal, described SR response is authorized and is adopted the special C-RNTI scrambling of user.
Generally, base station side normally should make uplink scheduling authorization to the SR dispatch request of terminal, if but cause present stage cannot carry out scheduling authorization to this terminal immediately due to dispatch delay or inadequate resource, if then judge to receive uplink scheduling request SRM time from certain terminal continuously, then must issue SR response mandate at once.This SR responds to authorize and adopts the special C-RNTI scrambling of user, and namely different user can be distinguished this SR and respond whether mandate is oneself.Effectively can distinguish the SR request not response caused due to inadequate resource or terminal disconnection like this, so SR response waits for that times N can be arranged relatively littlely detect to improve terminal the speed gone offline.Also can avoid from another point of view just in case really because resource anxiety causes not dispatching for a long time a certain terminal, self goes offline to cause this end-error to be thought simultaneously.
Thus, the method that the present embodiment and the response of the transmission described in preferred embodiment thereof are authorized, arrange independent SR response to authorize, it is only respond for the up SR dispatch request of terminal that this SR responds the object of authorizing, object informs that terminal base station side have received the SR request of terminal, knows that terminal has service needed uplink, and due to resource-constrained, temporarily really cannot carry out uplink scheduling to terminal, need to wait for.Such terminal just can be known and self do not go offline.Conversely, if terminal goes offline, then described base station just can not receive the SR request that terminal sends over, therefore also can not send SR response and license to terminal, when terminal is in predetermined wait times N is secondary, all do not receive the SR response mandate that base station sends, then terminal can judge that self goes offline in time.
The present invention makes terminal to know by the method that monitoring method and the transmission response of terminal disconnection are authorized, and whether self goes offline.Dispatch request SR is sent to base station by terminal, and regulation base station must send SR response to described terminal and authorize after the SR receiving M terminal transmission, if after terminal sends N dispatch request to base station continuously, N>M, still do not receive the SR response that base station sends to authorize, then described terminal just can be known and self goes offline.Compared to prior art, the present invention can arrange less N value, by judging whether that receiving SR response mandate knows whether self goes offline.The method of the invention can know self the situation that goes offline quickly, can avoid again the terminal disconnection erroneous judgement caused due to dispatch delay simultaneously.
