Access Layer is the bottom of Non-Access Stratum, and wherein the bottom is physical layer 20, is used for realizing various physical layer signal and processes function.MAC layer 21 is data link layer, is formed on physical layer 20 and link management on physical layer 20 between responsible mobile terminal and UTRAN.Rlc layer 22 is wireless chain control layer, defines the data link sub-layers of the wave point of UMTS with MAC layer 21.Rrc layer 23 includes for routeing higher message, processing broadcast and paging function, set up and configure multiple functional entitys of radio bearer etc..
Non-Access Stratum can utilize the service that rrc layer 23 is provided, and directly transmits including initial directly transmission, downlink and up-link directly transmission etc..Wherein, CC layer 30 is call control layer, for providing the call manager signaling of circuit-switched service, as set up signaling, the signaling etc. of kill-call connected.SS layer 31 is for providing the managing signaling of value-added service, and SMS layer 32 is for providing the managing signaling of SMS (Short Message Service), and the session management part of SM layer 32 provides PDP context activation, deexcitation and amendment function.Further, SM layer 32 is responsible for the foundation of radio bearer, is revised and discharge.MM layer 34 realizes the mobile management of mobile terminal.
According to existing protocol specification, need when kill-call to apply three signalings, be disconnect signaling (hanging up signaling), release signaling and release complete signaling respectively.As shown in Figure 3, if mobile terminal 14 actively kill-call, then sent disconnect signaling by mobile terminal 14 to UTRAN11, after UTRAN11 receives disconnect signaling, release signaling is sent to mobile terminal 14, after mobile whole 10 receive release signaling, send release complete signaling to UTRAN11.After UTRAN11 receives release complete signaling, the connection of Access Layer link could be discharged, namely UTRAN11 sends the signaling of RRC Connection Release to mobile terminal 14, after mobile terminal 14 receives the signaling of RRC Connection Release, sends, to UTRAN11, the signaling that RRC Connection Release completes.
Further, only mobile terminal 14 is after UTRAN11 sends release complete signaling, ability kill-call, and before call hang-ups, mobile terminal 14 will remain on call interface, and now user cannot be carried out other operations.
As communication network end is actively hung up the telephone, then being sent disconnect signaling by UTRAN11 to mobile terminal 14, mobile terminal 14 sends release signaling to UTRAN11, is finally sent release complete signaling by UTRAN11 to mobile terminal 14.
But, due to communication quality, mobile terminal 14 may not timely receive the signaling that UTRAN11 sends, and especially may not timely receive release signaling or release
Complete signaling, cause mobile terminal 14 can not discharge the connection of Access Layer link in time, namely cannot kill-call in time, after often leading to the button that user clicks on kill-call under call interface, mobile terminal 14 rests on call interface the most for a long time, affects the use of user.

Detailed description of the invention
The mobile terminal of the application present invention is the terminal with communication function, as the terminal of interactive voice can be carried out with the communication network of Universal Mobile Telecommunications System (UMTS), communication network includes that core net and UTRAN (land radio access web), mobile terminal and UTRAN carry out radio communication.Preferably, mobile terminal is the terminal supporting 2G or 3G voice call.
When mobile terminal and communication network realize the data interaction of voice call, if desired for kill-call, mobile terminal is needed to send disconnect signaling (hanging up signaling) to communication network or sent disconnect signaling by communication network to mobile terminal, the solution of the present invention is to have only to when kill-call apply disconnect signaling, the connection of Access Layer link is i.e. discharged after i.e. having only to mobile terminal or communication network transmission disconnect signaling, thus simplify the signaling transmission flow of kill-call, and enable mobile terminal quick closedown call function interface, reduce and user is used the impact caused.
First embodiment:
See Fig. 4, the call hang-ups device of the present invention has signaling sending module 40, call function interface is closed module 41, command reception module 42 and hangs up release module 43, command reception module 42 hangs up instruction for reception, namely receives the instruction of the kill-call that user sends.Signaling sending module 40 for being simultaneously emitted by discharging the signaling of the connection of Access Layer link when mobile terminal sends disconnect signaling.
Call function interface close module 41 when command reception module 42 receives and hangs up instruction, the call function interface of turning-off mobile terminal.Mobile terminal generally shows an interface under talking state, shows the information of call under this interface, and such as name, telephone number and talking state, the duration of call etc. of the other side, this interface is exactly call function interface.Further, generally dummy keyboard, kill-call button, hand-free call button etc. are also shown under call function interface.Under talking state, mobile terminal shows call function interface all the time, in the present embodiment, as long as mobile terminal sends disconnect signaling, namely receiving when hanging up instruction, call function interface is closed module 41 and is i.e. closed call function interface, thus call function interface is rapidly closed.
Owing to mobile terminal is when sending or receive signaling, need the content of signaling is analyzed, therefore, when mobile terminal sends the signaling including disconnect signaling content, i.e. close call function interface.
I.e. discharge the connection of Access Layer link owing to the solution of the present invention has only to application disconnect signaling, in order to reduce signaling quantity forwarded during kill-call, the content of disconnect signaling is incorporated in the release link-attached signaling of Access Layer.The release link-attached signaling of Access Layer includes RRC Connection Release signaling, signaling Connection Release signaling etc., and therefore, the content of disconnect signaling is incorporated in RRC Connection Release signaling, signaling Connection Release signaling.After mobile terminal have issued disconnect signaling, the release link-attached signaling of Access Layer, hang up the connection of release module 43 drop calls key-course immediately, and discharge the connection of Access Layer link, thus realize hanging up of call.
A kind of typical situation is as it is shown in figure 5, mobile terminal 50 actively kill-call in this case.When the kill-call button at call function interface is clicked, namely user have issued the instruction of kill-call, representing that user needs kill-call, after mobile terminal 50 receives and hangs up instruction, mobile terminal 50 needs to send disconnect signaling to communication network.In the present embodiment, mobile terminal 50 is included in RRC connection release request signaling to the content of the disconnect signaling that the UTRAN51 of communication network sends.So, after UTRAN51 receives RRC connection release request signaling, both perform to discharge the link-attached operation of Non-Access Stratum, perform again the operation that release RRC connects.
After UTRAN51 receives RRC connection release request signaling, the signaling of RRC Connection Release is sent to mobile terminal 50, after mobile terminal 50 receives the signaling of RRC Connection Release, the connection of drop calls key-course and the connection of release articulamentum link, and after discharging the connection of RRC link, send, to UTRAN51, the signaling that RRC Connection Release completes, thus discharge the connection of Access Layer link.
So, mobile terminal 50 and UTRAN51 just discharges the connection of Access Layer link after all needing not wait for receiving release signaling, release complete signaling.Certainly, at mobile terminal 50 after UTRAN51 sends the content of disconnect signaling, UTRAN51 may send release signaling to mobile terminal 50, and now mobile terminal 50 is not responding to release signaling, and still carries out the release link-attached operation of Access Layer.
Second embodiment:
See Fig. 6, the present embodiment has signaling receiver module 60, call function interface is closed module 61 and hangs up release module 63, signaling receiver module 60 sends the signaling of the connection of release Access Layer link for mobile terminal when receiving the disconnect signaling that communication network sends, or mobile terminal responds the signaling of the connection discharging Access Layer link that communication network sends when receiving the disconnect signaling that communication network sends simultaneously.
Module 61 is closed when signaling receiver module 60 receives the disconnect signaling that communication network sends in call function interface, the call function interface of turning-off mobile terminal, therefore, as long as mobile terminal receives the signaling including disconnect signaling content, call function interface is closed module 61 and is i.e. closed call function interface, thus call function interface is rapidly closed.
Hang up release module 63 for when receiving disconnect signaling, the connection of drop calls key-course, and discharge the connection of Access Layer link, thus realize hanging up of call.
Seeing Fig. 7, the present embodiment is the signaling that first communication network actively kill-call, i.e. UTRAN51 send the content including disconnect signaling to mobile terminal 50.In the present embodiment, the content of the disconnect signaling that first UTRAN51 sends to mobile terminal 50 is included in RRC Connection Release signaling, i.e. UTRAN51 had both comprised the content of disconnect signaling to the signaling that mobile terminal 50 sends, and comprised again the content that release RRC connects.
After mobile terminal 50 receives RRC Connection Release signaling, both the connection of Non-Access Stratum link had been discharged, discharge again the connection of Access Layer link, the namely connection connecting and discharging Access Layer link of drop calls key-course, and send, to UTRAN51, the signaling that RRC Connection Release completes.Visible, according to the solution of the present invention, mobile terminal 50 and UTRAN51 just discharges the connection of Access Layer link after all needing not wait for receiving release signaling, release complete signaling.So, mobile terminal still can close call function interface in the case of not receiving release signaling, release complete signaling, even if remaining to be rapidly completed hanging up of call in the case of signal quality is poor, and close call function interface, it is to avoid mobile terminal rests on other operations affecting user under call function interface for a long time.
Certainly, above-mentioned two situations are the content of disconnect signaling to be incorporated in the signaling of RRC Connection Release or the signaling of signaling Connection Release, during actual application, disconnect signaling still can individually be sent, as long as the signaling as Access Layer sends, namely it is included in the release link-attached signaling of Access Layer.As shown in Figure 8, in the case of mobile terminal 50 actively kill-call, first send disconnect signaling to UTRAN51, and send disconnect signaling simultaneously, also send the signaling forcing RRC connection release request to UTRAN51.Now, UTRAN51 will send RRC Connection Release signaling to mobile terminal 50, finally be sent RRC Connection Release by mobile terminal 50 to UTRAN51 and completes signaling, thus complete Non-Access Stratum link Connection Release and the Connection Release of Access Layer link.
And, it is shut off call function interface mobile terminal 50 sends disconnect signaling to UTRAN51 when, therefore call function interface is i.e. closed when the kill-call button under user's click to dial function interface, the transmission etc. forcing RRC connection release request signaling all performs on backstage, does not affect other operations of user.
Certainly, UTRAN51 will send release signaling to mobile terminal 50 after receiving disconnect signaling, mobile terminal 50 can be not responding to release signaling, release signaling can also be responded, i.e. send release complete signaling to UTRAN51, but mobile terminal 50 can't just perform to close the operation at call function interface after receiving release signaling or release complete signaling.
See Fig. 9, when communication network actively kill-call, UTRAN51 sends disconnect signaling to mobile terminal 50, when mobile terminal 50 receives disconnect signaling, the signaling forcing RRC connection release request is sent to UTRAN51, now, UTRAN51 will send RRC Connection Release signaling to mobile terminal 50, the connection connecting and discharging articulamentum link of mobile terminal drop calls key-course, finally sent RRC Connection Release by mobile terminal 50 to UTRAN51 and complete signaling, thus complete Non-Access Stratum link Connection Release and the Connection Release of Access Layer link.
In this case, mobile terminal closes call function interface when receiving disconnect signaling, call function interface closing velocity is very fast, it is to avoid mobile terminal rests on call function interface for a long time.Further, the connection of Access Layer link is i.e. discharged after mobile terminal receives disconnect signaling, it is to avoid wait until that receiving release complete signaling just discharges the connection of Access Layer link, thus shorten the release Access Layer link-attached time.
Certainly, after mobile terminal 50 receives disconnect signaling, it is also possible to send release signaling to UTRAN51, and not to receive the release complete signaling basis as closedown call function interface, more will not receive release
After complete signaling, just request release RRC connects.
Visible, according to the solution of the present invention, as long as mobile terminal 50 receives or sends and hangs up signaling and i.e. carry out the link-attached release of Access Layer, and close call function interface, when reducing kill-call while the quantity of applied signaling, the waiting time of kill-call with quick closedown call function interface, can be reduced.
Certainly; above-mentioned scheme is the preferred embodiment of the invention; actual application is to have more change; such as, the release link-attached signaling of Access Layer is not only RRC Connection Release signaling, it is also possible to be the signaling of signaling Connection Release; or the signaling of other Access Layer link Connection Releases; hanging up in the signaling that signaling can be incorporated into these Access Layer link Connection Releases, such change has no effect on the enforcement of the present invention, also should include within the scope of the present invention.
