In order to describe content of the present invention, resident the first service district belonging to the first wireless network (such as business network) of a RAT module (hereinafter referred to RAT1) be configured in communicator 200 can be supposed, enter " data pattern " to set up the circuit switching (CircuitSwitch with the first wireless network, or packet switching (PacketSwitch CS), PS) connect, and perform CS and PS transfer of data (such as voice/video data or packet data transmission) by wireless set 108 and antenna 109 in the first wireless network.Meanwhile, be configured in another RAT module (hereinafter referred to RAT2) on communicator 200 resident belong to second wireless network the second service district and the idle pulley (idlemode) entered for normal Standby.It should be noted that, in traditional design, when two RAT modules are assembled for communicator, when a RAT module take radio resource (such as wireless set 108 with antenna 109) performs CS or PS transfer of data time, another RAT module can enter " offline mode " to suspend its transmission and receiving function.
But, based on content of the present invention, in order to provide more effective radio traffic, during CS or the PS transfer of data of RAT module RAT1, can be RAT module RAT2 provides one or more gapping interval (gapinterval) to perform corresponding radio activity.Therefore, in an embodiment of the present invention, although RAT module RAT1 enters " data pattern " for CS or PS transfer of data, but RAT module RAT2 still can continue to be in the idle pulley (or so-called " virtual idle pulley " is to distinguish mutually with traditional communication device designs with a RAT) for normal Standby, and can continue in second wireless network, utilize radio resource (such as wireless set 108 and antenna 109) to receive and dispatch one or more message.
In order to implement the present invention, a moderator (arbiter) can be designed to arrange and to coordinate the radio activity of different RAT module.Such as, but be not limited to this, above-mentioned radio activity can be and send between respective cell (such as service district or neighbor cell) or the channel activity of the information of reception, or perform service district or the power scan of neighbor cell or the measurement activity of frequency scanning, or other radio activity.In certain embodiments of the present invention, can design one in real time time base (RealTimeBase, RTB) software module to arrange and to coordinate above-mentioned radio activity.When the running RTB software module of processor shown in processor 105 as shown in Figure 1 or Fig. 2, it can be changed into device, such as, arrange and the moderator coordinating radio activity between different RAT module.It should be noted that in other embodiments, also moderator can be designed to special hardware, the present invention is not limited to this.
In addition, in other embodiments, replace special-purpose software or hardware arbiter, also can communicate with one another for the treatment of individual task and/or representative of consumer identification card 101 protocol stack processor (protocolstackhandler) from RAT module 11 and 12 (or RAT module 11 ' and the 12 ') protocol stack of 102 thus arrange and coordinate the radio activity between different RAT module.Protocol stack processor can be made up of program code and be operated by aforesaid processor.It should be noted that and also can only operate a protocol stack processor to process the radio activity of RAT module simultaneously, the present invention is not limited to this.But when the processor 105 shown in Fig. 1 or the running of the processor shown in Fig. 2 protocol stack processor, it can be changed into the device implementing corresponding function.Fig. 4 describes the system configuration schematic diagram with the communicator of two protocol stack processors according to the embodiment of the present invention.When implemented, two protocol stack processor PS1 and PS2 have arrangement (or driving) wireless set 108 to perform the ability of data and signaling receiving and transmission activity respectively.Protocol stack processor PS1 and PS2 can communicate with one another with at arbitrary future time (also can be described as time slot or time frame) conversion radio resources control, and correspondingly plan radio resource.
Fig. 5 is the sequential chart of the radio activity that the different RAT modules described according to the embodiment of the present invention perform.As shown in Figure 5, the RAT module RAT1 of resident first service district enters " data pattern " and is connected with the PS of the first wireless network to set up, and by wireless set 108 and antenna 109 performing data transmission in the first wireless network.Therefore, the radio activity that RAT module RAT1 performs is transmission or reception by carrying out data and/or control signal between dedicated data channel (such as along multiple dedicated channels of shown time shaft) and the first wireless network.Meanwhile, the RAT module RAT2 of resident second community is in idle pulley.Gapping interval GAP_1 and GAP_2 can be routed to RAT module RAT1 with performing data transmission at first, but arrange to RAT module RAT2 to perform paging channel (as shown in PCH in figure) or the neighbor cell Broadcast Control Channel (as shown in NBCCH in figure) of listen for traffic community now, or perform power measurement (as shown in PM in figure).During above-mentioned gapping interval, suspend the transfer of data of RAT module RAT1 and RAT module RAT1 can not utilize radio resource to perform corresponding radio activity (therefore, as shown in the figure in gapping interval period DCH shadow representation).
But in implementation process, can find out, along with the gapping interval time is elongated, the data throughout of association RAT module RAT1 is by degradation and can occur excessively to take (excessive-and-consecutive-occupancy) problem continuously.The first wireless network connecting RAT module RAT1 can continue the confirmation of monitoring uplink data and/or coming from RAT module RAT1, and dynamically the transmission bandwidth of RAT module RAT1 is distributed in adjustment.Receive uplink data or confirmation more continually, the first wireless network can distribute to the larger transmission bandwidth of RAT module RAT1.But owing to there is gapping interval, the data throughout of association RAT module RAT1 reduces, and it slows down and sends the speed of uplink data or confirmation, so the downlink bandwidth that can obtain from the first wireless network will reduce.Such as, suppose that RAT module RAT2 takies several continuous gap interval to perform corresponding radio activity, the first wireless network also wishes to perform corresponding data transmit-receive to RAT module RAT1 simultaneously.When within continuous time, RAT module RAT1 does not perform data transmit-receive or can not respond the first wireless network, the downlink bandwidth that first wireless network distributes to RAT module RAT1 will sharply be reduced to very low level, more seriously, network can be made to assert, and RAT module RAT1 is in the state of radio link failure (RadioLinkFailure, RLF) and therefore disconnects PS connection.Once above-mentioned connection disappears, RAT module RAT1 must spend the more time set up new PS connection thus continue remaining data transmit-receive, causes larger data throughout to decline like this.Except above-mentioned situation about occurring in PS connection, in the CS of RAT module RAT1 connects, excessively the loss of continuous speech frame can make user listen to discontinuous or speak unclear and feel under the weather.Above-mentioned this situation is called occupation problem excessively continuously.
In order to prevent excessively continuously occupation problem and provide more reliable radio traffic, the invention provides to maintain and be configured in communicator 200 and share the method for the accepted quality of the communication service of at least two RAT module RAT1 and RAT2 of radio resource.Based on content of the present invention, during the transfer of data of RAT module RAT1 (gapping interval GAP_1 and the GAP_2 such as shown in Fig. 5), dynamic adjusts RAT module RAT2 at the idling mode and monitors the task performed by neighbor cell.
Fig. 6 is the method flow diagram for RAT module triggering tasks Regulation mechanism under idle pulley described according to the embodiment of the present invention.In step S602, processor can continue the communications status of monitoring RAT module.Then, in step S604, whether processor one of can determine in RAT module according to respective communication state has entered data pattern with performing data transmission.Typically, when RAT module is not just actively carrying out audio call with service district or data session communicates but still has the ability of receiving and dispatching one or more message in the wireless network, it can be described as and is being in idle pulley.When set up and service district carries out that audio call or data session communicate special be connected (CS or PS connects) time, RAT module is left idle pulley and is entered data pattern.If when processor determines that in RAT module has entered data pattern with performing data transmission, in step S606, the task that other RAT modules at the idling mode of processor dynamic conditioning perform.The details of task Regulation mechanism will be described further in paragraph below.
It should be noted that in certain embodiments of the present invention, processor can determine that RAT module enters data pattern when physical layer dedicated channel is set up.Such as, physical layer dedicated channel can be the gsm service channel (TrafficChannel into voice transfer foundation, TCH), be the GSM packet data traffic channel (PacketDataTrafficChannel of transfer of data foundation, PDTCH) the UMTS dedicated channel (DedicatedChannel, DCH), set up for voice or transfer of data or similar Traffic Channel.In other embodiments of the invention, when have received some specific upper layer message, by upper strata, processor also can determine that RAT module enters data pattern.Such as, particular message can be indicating circuit switching connection and has set up and the CC_CONNECTED message connected, or instruction has accepted to switch for dividing into groups the block data protocol context (PacketDataProtocolcontext connected, PDPcontext) PDP_CONTEXT_ACCEPT message, or similar message.
As described in front Fig. 5, the paging channel of above-mentioned gapping interval execution listen for traffic community and the task of monitoring neighbor cell can be utilized (such as to measure the signal power of neighbor cell for the RAT module RAT2 under the idle pulley of normal Standby, from neighbor cell receiving broadcast signal and decoding neighbor cell system information), wherein above-mentioned gapping interval is available to RAT module RAT1 at first for transfer of data.Normally, the communicator under idle pulley must monitor neighbor cell that is fixing and predetermined number (such as 6), thus collects enough neighbor cells for possible cell reselection.But, based on content of the present invention, in order to prevent excessively continuously occupation problem and provide more reliable radio traffic, the neighbor cell quantity that RAT module RAT2 monitors can carry out dynamic conditioning according to the situation of the situation of the service district of RAT module RAT2 and/or communicator 200.
According to the embodiment of the present invention, processor (processor 105 such as shown in Fig. 1 or the processor shown in Fig. 2) can comprise multiple processor logic unit of the one or more function of process separately.Such as, processor at least can comprise first processor logical block and the second processor logic unit, and wherein first processor logical block dynamically determines the quantity of the neighbor cell that RAT module RAT2 monitors during the transfer of data of RAT module RAT1 according to the situation of the service district of RAT module RAT2 and/or the situation of communicator 200; Second processor logic unit is used for promoting that RAT module RAT2 monitors the neighbor cell of above-mentioned decision quantity, and above-mentioned decision quantity is provided by first processor logical block.The neighbor cell of monitoring can have the signal stronger than other communities.In certain embodiments, processor can comprise the 3rd processor logic unit further, when RAT module RAT1 has entered data pattern performing data transmission, the situation of service district of the 3rd processor logic unit monitoring RAT module RAT2 or the situation of communicator 200.
Fig. 7 is the method flow diagram of the communication service quality of the RAT module that the maintenance described according to the embodiment of the present invention configures within a communication device.When in RAT module (such as a RAT module RAT1) has entered data pattern performing data transmission, in step S702, the quantity of processor logic unit neighbor cell that RAT module (such as RAT module RAT2) is at the idling mode monitored during can determining the transfer of data of RAT module in data mode, wherein above-mentioned decision draws according to the situation of service district of the RAT module under idle pulley and/or the situation of communicator.Then, in step S704, the RAT module under idle pulley can monitor the neighbor cell of above-mentioned decision quantity.
According to the embodiment of the present invention, it is number of times or the combination in any of the cell reselection that RAT module RAT2 produces that the situation of service district can comprise corresponding to the signal to noise ratio (SignaltoNoiseRatio, SNR) of service district or received signal intensity, time per unit.In addition, according to the embodiment of the present invention, the situation of communicator 200 can comprise the translational speed of communicator 200.The SNR corresponding to service district can be obtained when the paging channel of listen for traffic community.Received signal power by measuring service district obtains the received signal intensity corresponding to service district, such as received signal intensity instruction (ReceivedSignalStrengthIndicator, RSSI).The translational speed can estimated by correlation module (such as GPS module) or be the translational speed that RAT module RAT2 occurs that the number of times of cell reselection obtains mobile device 200 according to time per unit.Because the number of times of generation cell reselection also can increase when communicator 200 translational speed increases (i.e. mobile device 200 hyperlocomotion), so can think that the number of times that translational speed and time per unit produce cell reselection is proportional.
Based on content of the present invention, when the situation of service district is deteriorated (such as signal weakens) or moves too fast when communicator 200, the quantity of the neighbor cell of monitoring can increase.The quantity of the neighbor cell of monitoring can be greater than the predetermined quantity (such as 6) of normalized definition.In other words, the situation when service district improves (such as signal enhancing) or when communicator 200 move slack-off or do not move time, the quantity of the neighbor cell of monitoring can reduce or even can suspend monitoring neighbor cell task.Paragraph provides several embodiments of the quantity determining monitoring neighbor cell below.
According to the embodiment of the present invention, when SNR and/or RSSI determining to correspond to service district determines to increase, first processor logical block can reduce the quantity of the neighbor cell that RAT module RAT2 monitors.Because the positive grow of the signal power of service district, which imply that the possibility of cell reselection reduces, so first processor logical block can determine the quantity of the neighbor cell of reducing RAT module RAT2 monitoring, thus shorten the length of gapping interval or reduce the quantity of gapping interval, when performing monitoring neighbor cell task in above-mentioned gapping interval, RAT module RAT2 will hinder the transfer of data of RAT module RAT1.Gapping interval contraction in length or quantity minimizing can be alleviated the data throughout be associated with RAT module RAT1 and decline and can avoid occupation problem excessively continuously.
On the contrary, when SNR and/or RSSI determining to correspond to service district determines to reduce, first processor logical block can increase the quantity of the neighbor cell that RAT module RAT2 monitors.The quantity of the neighbor cell of monitoring can exceed the predetermined number (such as 6) of normalized definition.Because the signal power of service district just dies down, which imply that the possibility of cell reselection increases, so first processor logical block can determine the quantity of the neighbor cell increasing RAT module RAT2 monitoring, thus collect enough information for possible cell reselection.
Fig. 8 is the method flow diagram of the neighbor cell quantity that the dynamic conditioning described according to the embodiment of the present invention is monitored.When in RAT module (such as a RAT module RAT1) has entered data pattern performing data transmission, 3rd processor logic unit can keep SNR and/or RSSI of the corresponding service district of the RAT module (such as RAT module RAT2) of monitoring at the idling mode, and first processor logical block can obtain SNR and/or RSSI information from the 3rd processor logic unit.In step S802, first processor logical block periodically or aperiodically can determine whether SNR and/or RSSI corresponding to service district increases.If so, then in step S804, first processor logical block can reduce the quantity of the neighbor cell of monitoring.If not, in step S806, first processor logical block can determine whether SNR and/or RSSI corresponding to service district reduces further.If answer is yes, then in step S808, first processor logical block can increase the quantity of the neighbor cell of monitoring, if answer is no, then the neighbor cell quantity of monitoring remains unchanged.
According to another embodiment of the present invention, when the number of times that time per unit is RAT module RAT2 generation cell reselection is determined to reduce, first processor logical block can reduce the quantity of the neighbor cell that RAT module RAT2 monitors.Because the possibility that the number of times that time per unit is RAT module RAT2 generation cell reselection reduces translational speed and the cell reselection meaning communicator 200 reduces, so first processor logical block can determine the quantity of the neighbor cell of reducing RAT module RAT2 monitoring, thus shorten the length of gapping interval or reduce the quantity of gapping interval, wherein when above-mentioned gapping interval performs monitoring neighbor cell task, RAT module RAT2 will hinder the transfer of data in RAT module RAT1 future.
On the contrary, when the number of times that time per unit is RAT module RAT2 generation cell reselection is determined to increase, first processor logical block can increase the quantity of the neighbor cell that RAT module RAT2 monitors.Because the number of times increase that cell reselection occurs time per unit RAT module RAT2 means that the translational speed of communicator 200 and the possibility of cell reselection increase, so first processor logical block can determine the quantity of the neighbor cell increasing RAT module RAT2 monitoring, thus collect enough information for possible cell reselection.
Fig. 9 is the method flow diagram of the neighbor cell quantity that the dynamic conditioning described according to the embodiment of the present invention is monitored.When in RAT module (such as a RAT module RAT1) has entered data pattern performing data transmission, it is the number of times that RAT module (such as RAT module RAT2) at the idling mode produces cell reselection that 3rd processor logic unit can keep monitoring time per unit, and first processor logical block can obtain information from the 3rd processor logic unit.In step S902, first processor logical block periodically or aperiodically (such as at any time or event triggering situation) can determine time per unit is whether the number of times that under idle pulley, RAT module produces cell reselection reduces.If so, then in step S904, first processor logical block can reduce the quantity of the neighbor cell of monitoring.If not, in step S906, first processor logical block can determine that time per unit is that under idle pulley, RAT module produces the number of times of cell reselection and whether increases further.If answer is yes, then in step S908, first processor logical block can increase the quantity of the neighbor cell of monitoring, if answer is no, then the neighbor cell quantity of monitoring remains unchanged.
According to another embodiment of the present invention, when the translational speed of communicator 200 is determined to reduce, first processor logical block can reduce the quantity of the neighbor cell that RAT module RAT2 monitors.Because the reduction of communicator 200 translational speed means that the possibility of cell reselection reduces, so first processor logical block can determine the quantity of the neighbor cell of reducing RAT module RAT2 monitoring, thus shorten the length of gapping interval or reduce the quantity of gapping interval, wherein when performing monitoring neighbor cell task in above-mentioned gapping interval, RAT module RAT2 will hinder the transfer of data in RAT module RAT1 future.
On the contrary, when the translational speed of communicator 200 is determined to increase, first processor logical block can increase the quantity of the neighbor cell that RAT module RAT2 monitors.Because the increase of translational speed means that the possibility of cell reselection increases, first processor logical block can determine the quantity of the neighbor cell increasing RAT module RAT2 monitoring, thus collects enough information for possible cell reselection.
Figure 10 is the method flow diagram of the neighbor cell quantity that the dynamic conditioning described according to another embodiment of the present invention is monitored.When in RAT module (such as a RAT module RAT1) has entered data pattern performing data transmission, 3rd processor logic unit can keep the translational speed of monitoring communicator 200, and first processor logical block can obtain information from the 3rd processor logic unit.In step S1002, first processor logical block periodically or aperiodically (such as at any time or event triggering situation) can determine whether the translational speed of communicator reduces.If so, in step S1004, first processor logical block can reduce the quantity of the neighbor cell of monitoring.If not, in step S1006, first processor logical block can determine whether the translational speed of communicator increases further.If answer is yes, then in step S1008, first processor logical block can increase the quantity of the neighbor cell of monitoring, if answer is no, then the neighbor cell quantity of monitoring remains unchanged.
It should be noted that according to some embodiment of the present invention, when determining the quantity of neighbor cell of RAT module monitors at the idling mode, the situation of service district and the situation of communicator can together as considering.Such as, when determining the quantity of neighbor cell of RAT module monitors at the idling mode, time per unit produce the number of times of cell reselection, SNR, RSSI, communicator the combination in any of translational speed can together as considering.Therefore, the present invention should not be restricted to the described embodiments.
