Embodiment
Below discuss with reference to subscriber equipment.Subscriber equipment can present multiple multi-form and have a multiple difference in functionality.As an example, subscriber equipment can be can beat to connect wireless telephonic mobile phone.Subscriber equipment can also be the smart mobile phone that also moves general purpose application program answering the call except beating.Subscriber equipment can be in fact any equipment that is connected with network wireless, as other examples, comprise driver assistance module in vehicle, urgent transceiver, beep-pager, satellite TV receiver, the stereo receiver of networking, computer system, music player or any other equipment in fact.Below discuss and introduced the paging reception of how managing in the subscriber equipment that comprises a plurality of (for example, two) SIM.
Fig. 1 shows the example of the subscriber equipment 100 with a plurality of SIM, in this example, is SIM1 102 and SIM2 104.Electric and physical interface 106 is connected to SIM1 102 remainder of user device hardware, for example is connected to system bus 110.Similarly, electric and physical interface 108 is connected to system bus 110 with SIM2.
Subscriber equipment 100 comprises communication interface 112, system logic 114 and user interface 118.System logic 114 can comprise any combination of hardware, software, firmware or other logics.For example, system logic 114 can realize in SOC (system on a chip) (SoC), application-specific integrated circuit (ASIC) (ASIC) or other circuit.System logic 114 is parts of the implementation of any required function in subscriber equipment.In this respect, system logic 114 can comprise such logic, this logic for example is convenient to run application, accept user's input, preserve and the retrieve application data, set up, keep and end mobile phone communication, wireless network connection, bluetooth connection or other connections, and show relevant information on user interface 118.User interface 118 can comprise graphic user interface, touching-type monitor, voice or face recognition input, button, switch and other user interface elements.
Communication interface 112 can comprise one or more transceivers.Transceiver can be wireless transceiver, and it comprises modulation/demodulation circuit, amplifier, modulus and digital-to-analogue translator and/or is used for by one or more antenna or passes through other logics that physics (for example, cable) medium sends and receives.As a kind of example of realizing, communication interface 112 and system logic 114 can comprise BCM2091EDGE/HSPA multi-mode, multiband handset transceiver and the BCM59056 Advanced Program Zoom unit (PMU) that controlled by BCM28150HSPA+ SOC (system on a chip) (SoC) base band smart mobile phone processor.These integrated circuits, and can buy from the Botong company of California Irvine for other hardware and the software implementation options of subscriber equipment 100.The signal that sends and receive can be observed the combination in any in the various combinations of various forms, agreement, modulation, frequency channels, bit rate and the coding of the communication of supporting at present or in the future to comprise the page notification that is associated with SIM.As an instantiation, communication interface 112 can be supported transmission and the reception under universal mobile telecommunications system (UMTS).Yet following technology is applicable to other communication technologys that comprise paging, no matter whether this paging (TM) is made great efforts by third generation partner program (3GPP), GSM (R) association, Long Term Evolution (LTE) or other partnerships or standards body cause.
In one implementation, system logic 114 comprises one or more processors 116 and memory 120.For example, the controller instruction 122 of 120 pairs of processors of memory, 116 execution is stored.As describing in more detail hereinafter, controller instruction 122 helps call forwarding resource between a plurality of SIM of backstage page monitoring or regular register update, and for example communication interface 112.
SIM1 102 and SIM 104 can be on identical or different networks, and can be served by identical or different residential quarter (cell, honeycomb).For example, network controller A128 can manage the specific cell that SIM1 102 connects, and network controller B 129 can manage the different districts that SIM2 104 connects.
SIM1 102 and SIM2 104 can share the access to communication interface 112.One group of transceiver circuit that for example, can exist SIM1 102 and SIM2 104 all to share with time division way.As a result, which SIM is system logic 114 can determine to specify use communication interface 112, because SIM1 102 and SIM2 104 can't be in effective status simultaneously on communication interface 112.
The application is with reference to virtual modem.Virtual modem can refer to the software realization mode of the physical resource of subscriber equipment 100, for example passes through hardware virtualization.As mentioned above, for communication interface 112, subscriber equipment 100 can comprise one or more groups physics base band or RF resource, for example encoder/decoder, modulator, amplifier and antenna.Virtual modem can represent the software virtual in the RF path of any resource in communication interface 112.Therefore, each SIM of subscriber equipment 100 can be assigned with virtual modem, therefore and identify and uses the virtual communication resource of virtual modem, communicating by network, and need not to understand or process the complexity that causes because of shared RF path hardware between a plurality of SIM.Independently virtual modem can be specific and distribute to each SIM, to communicate by each network that each SIM was connected.In other words, a plurality of virtual modems can sharing users equipment 100 one group of common physical communication resources, and virtual modem is managed and is controlled by the virtual modem logic, the virtual modem logic is for example the virtual machine controller, and it can be realized in hardware, software or the two.As an example, the virtual modem logic can be for the access of each SIM scheduling or management RF path hardware, and the request that virtual modem is proposed responds, with for specific SIM access RF path resource.
Fig. 2 shows the sequential example 200 of backstage page monitoring.This sequential example 200 has been described system logic 114 and how have been coordinated at a plurality of SIM, for example common share communication interface 112 between SIM1 102 and SIM2 104.Fig. 2 utilizes dash area to describe sharing along the communication interface 112 of each time shaft of SIM1 and SIM2.As shown in Figure 2, system logic 114 effectual time 210 to SIM1 on communication interface 112 is dispatched.Yet, for following reason, system logic 114 is connected to communication interface 112 with SIM1 102 within the time of t1-t2, t3-t4, t5-t6 and after t7, and distribute simultaneously time slice in SIM1 effectual time 210, to allow SIM2 104 to be connected to communication interface 112, be t2-t3, t4-t5 and t6-t7 time durations in this example.
In other words, system logic 114 is dispatched and coordinates the data communication of SIM1 102 and SIM2 104 during a SIM effectively connects 210.For example, SIM1 102 can set up circuit switching (CS) and connect during a SIM effectively connects 210, and for example voice call connects.Alternately, SIM1 102 can set up packet switching (PS) and connect during a SIM effectively connects 210, for example so that the executing data transmitted in packets.
When SIM1 102 is in effective status on communication interface 112 (for example, during PS or CS conversation), perhaps SIM2 104 can't send or receive data.As a result, SIM2 104 perhaps can't monitor for pages channel or paging receiving designator.As a result, SIM1 102 was in effective status on communication interface 112 when, SIM2 104 can not receive and be intended to notify the SIM2 Paging Indicator of 104 incoming call voice calls.In order to allow SIM2 monitor for pages information, system logic 114 can be determined (identification) paging transfer time during the effective connection 210 of a SIM.When paging makes communication interface 112 transfer to SIM2 104 if can being indicated for any reason (for example monitoring comprises the beep-page message of Paging Indicator) transfer time.In sequential example 200, the 3rd paging transfer time 216 when the second paging transfer time 214 when first paging transfer time 212 when custom system logical one 14 has been determined time t2, time t4 and time t6.When paging 212-216 transfer time, system logic 114 makes communication interface 112 transfer to SIM2 104 from SIM1 102.As a result, as shown in sequential example 200, SIM2 104 is in effective status at time t2-t3, t4-t5 and t6-t7 on communication interface 112, although these time windows are in the SIM1 effectual time 210 of original plan (scheduled).
During transfer time, for example in transfer time 212-216, SIM2 104 can attempt the paging receiving designator by the monitor for pages indicator channel.After attempting the paging receiving designator, system logic 114 can be returned communication interface 112 SIM1 102 and effectively be connected 210 to continue a SIM.When SIM2 104 receives the Paging Indicator of the incoming call connection of indicating SIM2 104, system logic 114 can continue as the access on SIM2 104 license communication interfaces 112, the selected aspect that connects to process incoming call, and communication interface 112 is not returned SIM1 102.
System logic 114(for example utilizes controller instruction 122 to realize) can determine in several ways effective paging transfer time that connects during 210 at a SIM.As an example, subscriber equipment 100 can be stored SIM1 paging time sequence information 124 and the SIM2 paging time sequence information 125 that represents when Paging Indicator will be transferred to from network controller subscriber equipment 100.Therefore, system logic 114 can be determined paging transfer time in order to make communication interface 112 transfer to SIM2 104 based on SIM2 paging time sequence information 125.System logic 114 can be determined other transfer times in order to make communication interface 112 transfer to SIM2 104 during a SIM effectively connects 210, as described below.
System logic 114 can also determine to indicate communication interface 112 to be transferred to the SIM2 paging how long transfer duration.Therefore, system logic 114 can be transferred to SIM2 to continue the paging transfer given time of duration with communication interface 112 in paging transfer time.As seen in Figure 2, to shift the duration be t2-t3 in the paging of first paging transfer time 212.Similarly, to shift the duration be t4-t5 in the paging of second paging transfer time 214.It can be the scheduled time value that is applied to one or more situations when system logic 114 makes communication interface 112 transfer to SIM2 104 to be convenient to the backstage page monitoring that the duration is shifted in paging.The duration is shifted in paging can be identical for each shifts or can be different.The number of times that paging is shifted and duration can be selected to satisfy affects evaluation criterion.For example, affect evaluation criterion and can be, to the interruption of the activity of SIM1 lower than specified quantitative, for example the predetermined percentage (for example, 10%) lower than SIM1 effective time 210 is assigned to another SIM, and the predetermined percentage that reduces lower than the SIM1 bandwidth (for example, 15%), can be maybe other standards.For example, network controller can will affect evaluation criterion and pass to subscriber equipment 100 in control channel.Alternatively or additionally, user interface 118 can be accepted the user-selected evaluation criterion that affects.
As an instantiation, system logic 114 can paging shifts the length of duration and is set to long enough, for example 20ms concerning SIM2 104 monitor for pages channels and paging receiving designator.Perhaps, system logic 114 can paging shifts the duration and is set to be at least the shortest time concerning SIM2 104 paging receivings.It is variable that the duration is shifted in paging, and can according in paging signal intensity, paging perhaps any other factor change.Because the time of paging receiving or monitor for pages channel is relatively short, therefore can be lower on the impact of SIM1 PS or CS conversation.In this way, system logic 114 can produce the gap to allow SIM2104 monitor for pages information during a SIM effectively connects 210.Memory 126 can the memory scheduling parameter, and these parameters can comprise that paging transfer time, paging shift the duration, and the effectual time of SIM1 102 and SIM2 104.
Fig. 3 shows that wherein system logic 114 can be at the example of hardware, software or the controller logic of realizing in the two 300.For example, controller logic 300 can be embodied as controller instruction 122 in software.For example, effectively connect during 210 at a SIM, controller logic 300 can determine that SIM1 102 is in effective status (302) on communication interface 112.During this period, SIM2 104 can be in Suspend Mode (for example, be stationed in the residential quarter, and be not in effective status on communication interface 112).Controller logic 300 then can determine paging transfer time so that communication interface 112 is transferred to SIM2 104, thus monitor for pages channel (304).Controller logic 300 can also determine that designated communication interface 112 can transfer to the paging of the time quantum of SIM2 104 and shift the duration (306).
Effectively connect during 210 at the first user determination module, SIM2 can receive the Paging Indicator whether indication incoming call voice call points to SIM2.Controller logic 300 can receive from SIM2 the indication (308) of incoming call voice call.Then, controller logic 300 can determine that it is that voice call connection or packet connect (310) that the first user determination module effectively connects 210.In statement, alternately, controller logic 300 can determine whether SIM1 is in effective status on the communication interface 112 of carrying out PS conversation or CS conversation.
If SIM1 is carrying out the PS conversation when the incoming call voice call to SIM2 arrives, controller logic 300 can interrupt the effectively connection 210 of first user determination module, thereby interrupts the SIM1PS conversation.For this reason, controller logic 300 can prevent from returning to SIM1(312 in the communication interface 112 that makes at last of paging transfer duration), and communication interface 112 is distributed to SIM2 104 to process incoming call voice call (314).
If SIM1 is carrying out the CS conversation when the incoming call voice call to SIM2 arrives, controller logic 300 can connect with network, so that caller-marking (calling part ID) information that retrieval is associated with the incoming call voice call.In one implementation, controller logic 300 can be determined extra transfer time with the calling part ID information of retrieval incoming call voice call, and makes communication interface 112 transfer to SIM1 102 until determined transfer time.Alternately, before communication interface 112 was returned to SIM1 102, controller logic 300 can be retrieved calling part ID information.
In order to connect with network, controller logic 300 can be determined to set up with it network controller (316) that network is connected and retrieves calling part ID information.The process of obtaining calling part ID information can be followed the signaling sequence of the establishment of any specific communication standard regulation.For example, controller logic 300 Radio Resource can be connected (RRC) the connection request transmission of messages to network controller (for example, network controller B129).Next controller logic 300 can receive the RRC connection and set up message, and it can comprise channel allocation.Controller logic 300 can also communicate to transmit the RRC connection setup complete message with network controller, the initial directly message transfer of transmission, and receive the measurement control message.In addition, controller logic 300 can be between SIM2 104 and network controller exchanging safety mode command message and radio bearer set up message.In case radio bearer is set up and completed, controller logic 300 then just can be by receiving the calling part ID information that the conversation alarm information is retrieved the incoming call voice call from network controller.Controller logic 300 can determine that network controller can send or the time of communicating by letter of reception and SIM2, for example so that the allocation of downlink channel.
In case retrieve calling part ID (318), controller logic 300 can be notified the incoming call voice call on user SIM2 (320), allows the user to determine whether interrupt the first user determination module and effectively connects 210(322).For example, controller logic 300 can be to accept or the inquiry of refusal incoming call voice call to user interface 110 issues.When accepting conversation, for example, if the user accepts incoming call voice call (324) on SIM2 by user interface 110, controller logic 300 can interrupt the first user determination module and effectively connects 210 and make communication interface 112 transfer to SIM2 104 to process incoming call voice call (314).When the refusal conversation, for example, if the incoming call voice call that the user refuses on SIM2 by user interface 110, controller 700 can return to SIM1 102(326 with communication interface 112) effectively connect 210 to continue the first user determination module.System logic 114 can determine whether otherwise to accept or refuse incoming call.For example, system logic 114 can read decision parameters from memory 120.As an example, decision parameters can be indicated and should be refused or accept all incoming calls.As another example, decision parameters can be indicated the incoming call that should refuse or accept with some calling part ID coupling.
Fig. 4 shows that wherein system logic 114 can be at the example of hardware, software or the controller logic of realizing in the two 400.For example, controller logic 400 can be embodied as controller instruction 122 in software.Controller logic 400 can determine that SIM1 102 is in effective status (402) on the communication interface 112 of carrying out CS conversation (for example, language conversation).Similar with controller logic 300, controller logic 400 can determine paging transfer time (404) so that communication interface 112 is transferred to SIM2 104, thus the monitor for pages channel, and the duration (406) is shifted in definite paging.
Effectively connect during 210 at the first user determination module, when SIM1 was carrying out the CS conversation, the Paging Indicator of the incoming call voice call of SIM2 was pointed in the SIM2 indication that can receive and decode.Controller logic 400 can receive the indication (408) from the incoming call voice call of SIM2.As response, controller logic 400 at first starting protection timer (410) is transferred to the time quantum of SIM2 with limiting telecommunication interface 112, as described below.As an example; the protection timer can be set as a time length; even make, communication interface is distributed to SIM2 104, the network that SIM1 102 connects can not disconnect (or expection can not disconnect) first user determination module yet and effectively connect 210 when the protection timer expires.The length of protection timer for example can be 5-15 second, and this depends on network configuration.The length of protection timer can also be shorter, to reduce the impact on the SIM1CS conversation.
If the protection timer expired before SIM2 104 retrieves calling part ID information (414), controller logic 400 can be ended the trial (416) of the retrieval calling part ID of SIM2 104.Controller logic 400 for example can be controlled by time-out the virtual machine of SIM, or indicates virtual machine to discharge to end to attempt, and makes the access to communication interface 112 finish and communicate by letter to stop.For example, controller logic 400 can suspend the virtual machine of controlling SIM, or the release of indication virtual machine, makes SIM finish and communicate by letter to stop to the access of communication interface 112.Then controller logic 400 can send communication interface 112 back to SIM1 and effectively connect 210(418 to recover the first user determination module).
If SIM2 104 connected with network and retrieved calling part ID information before the protection timer expires, controller logic 400 can stop protecting timer (420).Controller logic 400 then can be by stopping communicating with network controller the incoming call voice call (422) of automatically refusing to SIM2 104.Then controller logic 400 for example can present incoming information to the user by user interface 118.Incoming information can comprise that subscriber equipment 100 receives that the time of incoming call voice calls, incoming call voice call are pointed to the indication of SIM2 104 or the calling part ID information of the incoming call voice call that retrieves.Controller logic 400 can also be sent communication interface 112 back to SIM1 and effectively be connected 210(418 to recover the first user determination module).
Fig. 5 shows the sequential example 500 of regular register update.Even if when hanging up, SIM2 104 also can monitor the Paging Indicator of automatic network, as described in above-mentioned Fig. 2-4.In order to keep and being connected of network, SIM2 104 can utilize network, for example carries out regular register update by sending network registry communication to the network controller (for example, network controller B129) of supporting SIM2 104.Carry out regular register update and can comprise the combination in any of carrying out the renewal of regular position, periodic RA updates or regular tracing section updating.
Network can be specified regular registration time sequence information, and this is regularly registered time sequence information and has specified subscriber equipment 100 or system logic 114 can carry out the period of regular register update, so that SIM(is for example, SIM2 104) keep connected to the network.Regularly the registration time sequence information can comprise the time sequence information relevant with carrying out the renewal of regular position, periodic RA updates or regular tracing section updating.This network can pass through network controller, and for example network controller B129 will regularly register time sequence information and pass to subscriber equipment 100 and SIM2 104.Therefore, if SIM2 104 can't be transferred to network controller with regular register update with the frequency of the regular registration time sequence information regulation of network, this network can disconnect and being connected of SIM2 104.In this case, SIM2 104 can can't successfully monitor suitable paging channel or paging receiving designator.
(for example, carry out PS or CS conversation) when SIM1 102 is in effective status on communication interface 112, perhaps SIM2 104 can't carry out regular register update to keep network to connect to network controller.Therefore, system logic 114 can determine that the first user determination module effectively connects transfer time during 210 so that communication interface 112 is transferred to SIM2, carries out selected communication, for example register update to utilize the network of supporting SIM2.
In sequential example 500, system logic 114 determined time t2 as transfer time 402 so that communication interface 112 is transferred to SIM2 104, thereby utilize network to carry out register update.System logic 114 can optionally make communication interface 112 transfer to SIM2 104 in transfer time.For example, system logic 114 can connect based on the first user determination module 210 connection type, and for example PS conversation or CS conversation determine to shift decision-making.The transfer decision-making also can relate to makes communication interface 112 transfer to the certain mass level whether SIM2 can keep the effective connection 210 of first user determination module, and can comprise any evaluation criterion that affects discussed above.In sequential example 500 shown in Figure 5, system logic 114 can optionally make communication interface transfer to SIM2 104 in transfer time 502.SIM2 104 can carry out from time t2 to t3 the renewal of regular position, periodic RA updates or regular tracing section updating to keep network to connect.In case SIM2 104 completes register update, system logic 114 just can be returned communication interface 112 SIM1 and effectively be connected 210 to continue the first user determination module.
Fig. 6 shows that wherein system logic 114 can be at the example of hardware, software or the controller logic of realizing in the two 600.The same with controller logic 300 and controller logic 400, controller logic 600 can be embodied as controller instruction 122 in software.Controller logic 600 can determine that the first user determination module effectively connects transfer time (602) during 210 so that communication interface 112 is transferred to SIM2 104, thereby carries out regular register update.For example, controller logic 600 can obtain regular registration time sequence information (604) from network controller.When system logic 114 or SIM2 104 successfully initiated with being connected of network, the regular registration time sequence information of network can be transmitted by network controller.Controller logic 600 can configure regular registration timer (606) based on the regular registration time sequence information of the reception of obtaining.As an example, regularly registration timer can be configured to expire after enough time, so that SIM2 carries out register update to keep network to connect, for example sends regular position and upgrades.Controller logic 600 can configure similarly regular registration timer in order to carry out periodic RA updates or regular tracing section updating, and this depends on the configuration of network.Controller logic 600 can be set as transfer time in the regular registration timer that configures the expiration time (608) of any one.
Alternately, can the logic that regular registration time sequence information is processed and utilization is associated with SIM2 104 be configured regular registration timer.In this implementation, controller logic 600 can be determined transfer time in order to carry out regular register update when receiving request from SIM2.
When regular hour of log-on expired, controller logic 600 can determine that SIM1 is in effective status (610) on communication interface 112 and starting protection timer (612) is transferred to the time span of SIM2 104 to control communication interface 112.Then controller logic 600 can optionally make communication interface 112 transfer to SIM2 104 to carry out regular register update (614).In one implementation, when SIM1 (is for example carrying out the CS conversation, voice call) time, controller logic 600 can come optionally call forwarding interface 112 by not making communication interface 112 transfer to SIM2 104, on the contrary, SIM1 102CS conversation has precedence over the SIM2 104 that keeps network to connect by carrying out regular register update.Alternately, controller logic 600 can make communication interface 112 transfer to SIM2104, no matter whether SIM1 carries out PS conversation or CS conversation during the first user determination module effectively connects 210.
Fig. 7 shows regular position and upgrades 700 example.SIM(is SIM2 104 for example) can be by subscriber equipment 100(and be specially SIM2 104) with network controller 710 between a series ofly communicate by letter to carry out regular position and upgrade 700.Upgrade in order to carry out regular position, SIM2 104 can be transferred to network controller 710 with channel request message 720, and this network controller 710 can utilize instant assignment messages 722 to respond.Next, SIM2 104 can transmission location update inquiry information 724.Network controller 710 then can certified transmission request message 726, and SIM2 104 can certified transmission response 728.Can carry out the similar exchange of message between SIM2104 and network controller 710, these message and encryption mode are (for example, 730 and 732), the sign of subscriber equipment 100 (for example, 734 and 736) and Temporary Mobile Subscriber Identity (TMSI) (for example, 738 and 740) are relevant.Then network controller 710 can the transmission location renewal accept message 742.SIM2 104 can respond by channel release message 744 is transferred to network controller 710, and this SIM2 can complete regular position and upgrade.
Fig. 8 shows the example of periodic RA updates 800.SIM(is SIM2 104 for example) can be by subscriber equipment 100(and be specially SIM2 104) with network controller 810 between a series ofly communicate by letter to carry out periodic RA updates 800.At first, SIM2 104 can be transferred to network controller 810 with packet channel request message 820.Network controller 810 can respond by packet uplink assignment message 822 is transferred to SIM2 104.Next, SIM2 can transmission route district's update inquiry information 824, and network controller 810 can respond by transmission packet downlink assignment message 826.After this, network controller 810 and SIM2 104 can exchange the message relevant with the sign that authenticates, encrypts (for example, 828 and 830) and subscriber equipment 100 (for example, 832 and 834).Then network controller 810 can transmission route district's renewal accept message 836.Then SIM2 104 can complete Routing Area Update message 838 and be transferred to network controller 810, and this SIM2 can complete periodic RA updates.
Fig. 9 shows the sequential example 900 that the backstage page monitoring is seized.In this sequential example 900, SIM1 102 can carry out PS conversation or CS conversation during the first user determination module effectively connects 210.Effectively connect during 210 at the first user determination module, system logic 114 can be determined paging transfer time, for example paging transfer time 912 and paging transfer time 914, can to make communication interface 100 transfer to SIM2 104 movable to carry out the backstage page monitoring for subscriber equipment 100 during this period.As shown in Figure 9, SIM2 can the monitor for pages channel or from the paging transfer time 912 between t2 and t3 and paging paging receiving designator transfer times 914 between t4 and t5.
System logic 114 can determine that the first user determination module effectively connects during 210 the special time period when the first user determination module can be carried out high priority and communicates by letter, for example in sequential example 900 from time t6 to t7.Be shown as in this time of seizing the period, system logic 114 can be seized the transfer of communication interface 112 to SIM2 104.For example, when SIM1 102 is in effective status on communication interface 112, when carrying out the PS conversation, system logic 114 can determine that SIM1 carries out the time of high priority communication.System logic 114 can be passed through multitude of different ways, for example according to them on the performance of SIM1 102PS conversation or the impact of throughput, communication is classified as high priority.For example, if SIM1 102 is being under packet transfer mode when losing with the communication interface 112 of network controller maybe when the important up link control message of transmission, throughput, quality or other characteristics that SIM1 102PS converses may be reduced to lower than predetermined threshold.In these situations, system logic 114 can suppress the interruption that SIM1 connects.The uplink message that is transferred to network controller by SIM1 102 can comprise transmission Radio Link message, access control message, packet uplink acknowledgement message, transmission control protocol (TCP) acknowledge message or packet downlink ack message.System logic 114 can be defined as these times suppressing seize the period (for example, the seizing the period 920) of SIM2 access.
As an example, system logic 114 can be determined paging transfer time in the time of t6-t7.System logic 114 can also determine that SIM1 102 is scheduled in order to from t6 to t7, important up link control message is transferred to network controller, can be defined as seizing a period of time of period 920 by system logic 114 from t6 to t7.Because during paging appears at and seize the period 920 transfer time, so system logic 114 can be seized communication interface 112 to SIM2's 104 in order to carry out the transfer of backstage page monitoring activity during seizing the period 920.
Figure 10 shows that wherein system logic 114 can be at the example of hardware, software or the controller logic of realizing in the two 1000.For example, controller logic 1000 can be embodied as controller instruction 122 in software.Controller logic 1000 can be determined to be in effective status (1002) on the communication interface 110 of the grouping of SIM1 102 in transmission PS conversation.Effectively connect during 210 at the first user determination module, controller logic 1000 can determine that SIM1 102 will carry out the special time period (1004) of high priority communication, the example that for example above conversation is discussed for PS.(for example, seize the period 920) during special time period, controller logic 1000 can be seized the transfer (1006) of communication interface 112 to SIM2 104, for example is used for SIM2 104 and carries out backstage page monitoring activity.
In one implementation, controller logic 1000 can be transferred to the regular register update of the preferential SIM2 104 of SIM2 104 by making communication interface 112 during seizing the period, make SIM2 104 can carry out regular register update.Alternately, controller logic can also be seized communication interface 112 to SIM2 104 in order to carry out the transfer of regular register update during seizing the period.
Figure 11 shows the sequential example 1100 that improves subscriber equipment 100 throughputs.In this sequential example 1100, effectively connect during 210 at a SIM, SIM1 102 is in effective status on communication interface 112.Effectively connect during 210 at a SIM, SIM1 102 can carry out PS conversation or CS conversation, or the network service of any other type.Effectively connect during 210 at a SIM, during SIM1 102PS conversation, SIM1 102 can be to high priority communication between t2 to t4, and for example the execution of high priority uplink communication 1110 is dispatched.When SIM1 102 will carry out high priority communication, system logic 114 can determine that a SIM effectively connects the high priority access time during 210.System logic 114 can also determine to permit for example SIM2 104 of idle SIM(during at least a portion of high priority access time) accessing communication interface 112, thus the timing conflict that causes high priority to communicate by letter.For example, system logic 114 can be determined paging transfer time 1120 between time t3 to t4 so that communication interface 112 is transferred to SIM2, thereby it is movable to carry out the backstage page monitoring, or any other required network service.
Backstage page monitoring (BPM) activity shown in Figure 11 can comprise normal priority BPM movable 1130 and high priority BPM activity 1140.It is movable that normal priority BPM activity 1130 can comprise time insensitive backstage page monitoring, and for example multipath search activity or neighboring cell search are movable.High priority BPM activity 1140 can comprise that time-sensitive type backstage page monitoring is movable, monitor for pages indicating channel for example, monitor for pages channel or decoding paging.
Timing conflict (or alternately being called access conflict) is present between t3 to t4 between the high priority communication of carrying out SIM1102 and the backstage page monitoring activity of carrying out SIM2 104.System logic 114 can be carried out the conflict that solves timing conflict and solve action, does not for example interrupt high priority communication during the high priority access time.Solve an example of action as conflict, system logic 114 can be divided the selection section of BPM activity and rescheduled, therefore carry out high priority communication not can with carry out the BPM activity overlapping.In Figure 12, system logic 114 has been rescheduled to normal priority BPM activity 1130 time early, with the solution timing conflict, and need not to interrupt high priority communication during the high priority access time.Additionally or alternatively, system logic 114 can be by rescheduling the high priority communication of conflict, for example the high priority uplink communication 1110, carrying out conflict and solving action, to solve timing conflict.In some implementation, system logic 114 can will reschedule the following degree that is restricted to: rescheduling of high priority uplink communication 1110 is no more than predetermined threshold to the throughput of SIM1102PS conversation or the impact of some other feature.
In addition, if schedules high priority uplink communication 1110 conflicts with high priority BPM movable 1140, system logic 114 can also be rescheduled to high priority uplink communication 1110 degree that rescheduling of high priority uplink communication 1110 do not affect the throughput of SIM1 102 PS conversations.Yet if high priority uplink communication 1110 can't reschedule, system logic 114 can determine that communication interface 112 is distributed to SIM1 still distributes to SIM2 to carry out high priority activity 1140 to carry out high priority communication 1110.
Figure 12 shows the sequential example 1200 that improves subscriber equipment 100 throughputs.Sequential example 1200 from sequential example 1100 got and described normal priority BPM activity 1130 is rescheduled in case with the sequential of carrying out high priority uplink communication 1110 and occur timing conflicts.Therefore, system logic 114 can solve aforementioned timing conflict between t3 to t4 by rescheduling normal priority BPM activity 1130, in order to begin and finish at time t2 at time t1a.
Due to the result that reschedules, system logic 114 can determine that now two pagings are movable to carry out SIM2 104 backstage page monitorings transfer time.When time t1a, system logic 114 can determine that paging is movable to carry out normal priority BPM transfer time 1130.At time t5, system logic 114 can determine that paging transfer time 1140 is to carry out high priority BPM activity 1140.As shown in figure 12, a SIM effectively connects 210 and is being interrupted twice between time t1a to t2 and between time t5 to t6, is convenient to SIM2 and carries out backstage page monitoring activity.System logic 114 can reschedule to minimize the time of carrying out between normal priority BPM movable 1130 and high priority activity 1140 to normal priority BPM effective 1130.
Figure 13 shows that wherein system logic 114 can be at the example of hardware, software or the controller logic of realizing in the two 1300.For example, controller logic 1300 can be embodied as controller instruction 122 in software.Effectively connect during 210 at a SIM, controller logic 1300 can determine that SIM1 is in effective status (1302) on communication interface 112.Then controller logic 1300 can recognize that SIM1 is scheduled in order to carry out high priority communication (1304) at special time period.Controller logic 1300 can also determine paging transfer time so that communication interface 112 is transferred to SIM2 104, thereby carries out backstage page monitoring movable (1306).Then controller logic 1300 can be determined to have timing conflict (1308) between SIM1 execution high priority communication and SIM2 execution backstage page monitoring activity.
If it is movable that timing conflict does not relate to high priority BPM, controller logic 1300 can reschedule normal priority BPM activity, to solve and to carry out the timing conflict (1318) that the SIM1 high priority is communicated by letter and occured.Then controller logic 1300 can determine the normal priority BPM activity that reschedules and the paging transfer time (1320) of high priority BPM activity.Controller logic 1300 can be carried out SIM1 102 high priority communications and carry out SIM2 104BPM movable (1322) with support by call forwarding interface 112.
Figure 14 shows the sequential example 1400 that improves subscriber equipment 100 throughputs.In this sequential example 1400, effectively connect during 210 at a SIM, SIM1 102 can be in effective status on communication interface 112.Effectively connect during 210 at a SIM, can dispatch in order to carry out high priority uplink communication 1110 between time t3 to t4 SIM1.Effectively connect during 210 at a SIM, paging transfer time 140 when system logic 114 can be determined time t5 is so that communication interface 112 is transferred to SIM2, thereby it is movable to carry out BPM, comprises normal priority BPM movable 1140 and high priority BPM activity 1130, as described in Figure 11.
Any potential timing conflict occurs for fear of communicating by letter with SIM1 102 high priorities, system logic 114 can reschedule normal priority BPM activity 1130, to guarantee that SIM2 104 carries out normal priority BPM activities 1130 and do not carry out high priorities (for example the high priority uplink communication 1110) conflict of not communicating by letter with SIM1 102.For this reason, system logic 114 can attempt rescheduling normal priority BPM activity 1130 rescheduling the period.Reschedule the period and can be the scheduled time length before plan time of implementation of BPM activity, for example shown in Figure 14 from rescheduling the period 1420 between t2 to t5.System logic 114 can determine whether normal priority BPM activity 1130 to be rescheduled to the time period (for example, time t2) that reschedules in the period 1420, and the execution of not communicating by letter with SIM1 102 high priorities clashes.In this sense, system logic 114 adopts the chance rescheduling algorithm by reschedule normal priority BPM movable 1130 at the earliest time point that reschedules the period, makes normal priority BPM activity 1130 not clash with the execution that SIM1 102 high priorities are communicated by letter.For example, system logic 114 can be rescheduled to the earliest time section that reschedules the period 1420 with normal priority BPM activity 1130, and this time period does not for example communicate by letter with high priority that high priority uplink communication 1110 clashes.
Reschedule the period and can be the scheduled time length of using when system logic 114 reschedules BPM activity (for example, normal priority BPM is movable).Can limit the length that reschedules the period, make normal priority BPM movable 1130 and high priority BPM activity 1140 not differ greatly in time and carry out.For example, normal priority BPM activity 1130 can comprise multipath search activity or neighboring cell search activity.The time of carrying out between normal priority BPM movable 1130 and high priority BPM activity 1140 is longer, just can not be so effective from the time sequence information of multipath search or neighboring cell search collection.
Yet even if rescheduled normal priority BPM activity 1130, as mentioned above, high priority BPM activity 1140 also may still conflict with high priority uplink communication 1110.In this case, system logic 114 if possible can reschedule high priority uplink communication 1110, or definite high priority uplink communication 1110 is preferential or high priority BPM movable 1140 is preferential.
Figure 15 shows the sequential example 1500 that improves subscriber equipment 100 throughputs.Sequential example 1500 has got and has described from sequential example 1400 and by the chance mode, normal priority BPM activity 1130 rescheduled so that at the time of sequential example 1400 t2(rather than t5) beginning sequential.In addition, system logic 114 can reschedule normal priority BPM activity 1130, and does not consider whether normal priority BPM activity 1130 conflicts with high priority uplink communication 1110.
In case reschedule normal priority BPM activity 1130, system logic 114 can be determined the paging transfer time of normal priority BPM movable 1130 and high priority BPM activity 1140.In sequential example 1500, system logic 114 has determined that paging transfer time 1510 when time t2 is to carry out normal priority BPM activity 1130.System logic 114 has determined that also paging transfer time 1520 is to carry out high priority BPM activity 1140.
Figure 16 shows that wherein system logic 114 can be at the example of hardware, software or the controller logic of realizing in the two 1600.Controller logic 1600 can be embodied as controller instruction 122 in software.Effectively connect during 210 at a SIM, at first controller logic 1600 can determine that SIM1 is in effective status (1602) on communication interface 112.Next, controller logic 1600 can be determined to reschedule the period and when begins (1604).That is to say, controller logic 1600 can recognize that certain time before SIM2 104BPM activity is scheduled, and wherein this certain time can be specified by predetermined value, thereby mark reschedules the starting point of period.
Next, controller logic 1600 can to analyzing in order to communicate (1606) on communication interface 112 through the transmitted in packets of scheduling, for example, continue the next inspection period of two 10ms frames.Alternately, controller logic 1600 can to analyzing through the transmitted in packets of scheduling, and continue the next inspection period of four 10ms frames.Controller logic 1600 can determine whether can be checking that to reschedule SIM2104 normal priority BPM in the period movable and avoid and carry out the time of origin conflict (1608) of communicating by letter of SIM1 102 high priorities, from the earliest time point that checks the period.
If so, controller logic 1600 can reschedule normal priority BPM activity the definite point (1610) the earliest into the time.Then controller logic 1600 can determine the normal priority BPM activity that reschedules and the paging transfer time (1612) of high priority activity.Next, controller logic 1600 can make communication interface 112 transfer to SIM2(1614 according to determined paging transfer time) movable to allow SIM2 to carry out the backstage page monitoring during a SIM effectively connects 210.
If controller logic 1600 can't reschedule normal priority BPM within the inspection period movable (for example, timing conflict occurs owing to communicating by letter with SIM1 102 high priorities), controller logic 1600 can determine whether to have considered the whole period (1616) that reschedules.If so, controller logic 1600 can can't reschedule normal priority BPM activity.Otherwise controller logic 1600 can be analyzed (1606) to the next part of scheduling slot again.
