Background technique

The term "wireless", generally referring to electrical or electronic operation, can be achieved without the use of "hard-wired" connections. "Wireless communication" is the transmission of information over a distance without the use of electrical conductors or wires. The distances involved can be short distances (a few meters for a TV remote control) or long distances (thousands or even tens of thousands of kilometers for radio communications). The mobile phone is the most well-known example of wireless communication. Cell phones allow users in many locations around the world to talk to each other using radio waves. A mobile phone can be used anywhere as long as there is a cellular telephone site to house equipment capable of sending and receiving signals that are processed for the mobile phone to send and receive voice and data.

Various mobile communication technologies are quite mature and well defined. For example, the Global System for Mobile communications (GSM) is a well-defined and widely adopted communication system that uses Time Division Multiple Access (TDMA) technology, which is used to transmit data between mobile phones and cell sites. A digital radio multiple access scheme for voice, data, and signaling data (such as dialed telephone numbers). CDMA2000 is a technical standard of hybrid mobile communication 2.5G/3G, which utilizes Code Division Multiple Access (CDMA) technology. Universal Mobile Telecommunications System (UMTS) is a 3G mobile communication system, and UMTS provides enhanced multimedia services on the 2GGSM system. Wireless Fidelity (Wireless Fidelity, Wi-Fi) technology is a technology defined by the 802.11b engineering technology standard. This technology can be used in home networks, mobile phones and video games to provide high-frequency wireless local area networks.

With the rapid development of wireless communication technologies, it is possible to use different or the same communication technologies in a mobile station (Mobile Station, MS) to provide multiple wireless communication services today. In order to provide optimal communication services, an intelligent method of prioritizing subscriber identification cards is required.

It should be noted that the storage device 106 can also be installed outside the baseband module 103, and the present invention is not limited thereto. It should be noted again that FIG. 1 is only an embodiment of the present invention, which is used to simplify the description of the present invention, so that readers can better understand the content of the present invention. Any wireless communication module that can provide wireless communication services can be combined with the present invention, and the present invention is not limited thereto. In addition, each of the aforementioned modules can be implemented as a single independent chip to provide corresponding functions, or can be integrated into a combined chip (ie, System on Chip, SoC for short), and the present invention is not limited thereto.

Figure 2 shows an example network according to an embodiment of the present invention. After a communication device 100 equipped with multiple subscriber identification cards is camped or associated with a cell managed by an access station 200, 201, 202, the communication device 100 can simultaneously access Multiple wireless networks 203 and 204 of radio access technologies (Radio Access Technologies, RATs), wherein the access stations 200, 201, 202 can be base stations, node-B or access points conforming to standards 802.1a, 802.1b or 802.1g and others. For example, the wireless network 203 and/or the wireless network 204 may be GSM, WCDMA, Wi-Fi, CDMA2000, Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network, Internet or similar networks. The communication device 100 can use at least one of the networks 203 and 204 with corresponding media devices 205, 206 and 208, or through the public switched telephone network (PublicSwitchedTelephoneNetwork, PSTN) 207 or any combination of the above-mentioned networks, using any subscriber identity card installed Send a device originating communication request (apparatus originated communication request) to the called party (that is, another corresponding wired or wireless communication device at the same level), such as a voice call, a data call, a video call or a voice call over Internet Protocol (VoiceoverInternetProtocol, VoIP), wherein , The communication request initiated by the device is also called a mobile device originated (Mobile Originated, MO) call request, and the networks 203 and 204 can be, for example, a GSM network with a mobile switching center (MobileSwitchingCenter, MSC), a radio network controller (RadioNetworkController, RNC) ) WCDMA/TD-SCDMA network or the Internet with a Session Initiation Protocol (SessionInitiationProtocol, SIP) server. In addition, the communication device 100 can receive an apparatus terminated communication request (apparatusterminated communication request), also called a mobile terminal (Mobile Terminated, MT) incoming call request, such as an incoming call from any subscriber identity card of the calling party. It should be understood that one or more gateways may exist between different types of networks.

According to an embodiment of the present invention, the subscriber identity cards 101-1, 101-2, ..., 101-N may conform to a type of wireless communication system. For example, the subscriber identity cards 101-1, 101-2, ..., 101-N may be Subscriber Identity Module (Subscriber Identity Module, SIM) cards conforming to the GSM communication system, and may be Universal Subscriber Identity Module (Universal Subscriber Identity Module, SIM) conforming to the UMTS communication system. USIM) card, Removable User Identity Module (RUIM) card, CDMA Subscriber Identity Module (CSIM) card or other types of cards conforming to the CDMA2000 communication system.

FIG. 3 is a schematic diagram of radio activity scheduling of a radio transceiver module shared by multiple subscriber identity cards according to an embodiment of the present invention. In this embodiment, the radio transceiver module 104 is shared by the subscriber identity cards 101-1, 101-2, ..., 101-N, and switches between the subscriber identity cards 101-1, 101-2, ... ..., 101-N (subscriber identity card X as shown in FIG. 3 ) packet switching (packetswitch, PS) data transmission. However, in the time period TP1, another subscriber identity card (subscriber identity card Y as shown in FIG. can perform its radio activity. During the interrupted period TP2, the subscriber identity card Y can perform any task in the normal idle mode through the radio transceiver module 104, such as listening to broadcast channel messages, control channel messages, paging channels, paging indication channel messages (below known as paging messages), signal quality measurements of serving or neighboring cells, and others. Therefore, based on the purpose of the present invention, when the subscriber identity card X mainly occupies the radio transceiver module 104 to perform PS data transmission, that is, the radio transceiver module 104 is mainly occupied by the subscriber identity card X under the packet transfer mode (PacketTransferMode, PTM) , other subscriber identity cards (such as the shown subscriber identity card Y) except the subscriber identity card (such as the subscriber identity card X shown in Figure 3) that performs PS data transmission can enter a kind of "virtual idle mode" without The transmitting and receiving functions of the radio transceiver module 104 are suspended during the time period TP1. In a preferred embodiment, multiple protocol stacks can be configured to separately handle the radio activity of each SIM card. However, it is also possible to equip only one protocol stack for handling the radio activities of all inserted SIM cards, and the invention should not be limited thereto. It is worth noting that before and after the interrupted period TP2, a transition period for switching the usage rights of the shared radio transceiver module 104 between different SIM cards is required.

According to an embodiment of the present invention, because when the subscriber identity card X is performing PS data transmission (that is, in the packet transmission mode), other subscriber identity cards (such as the subscriber identity card Y shown in FIG. 3 ) can enter the "virtual idle mode" ", so other SIM cards can still use the interrupted period to listen to the paging message, so as not to lose the incoming call (ie MT call) when the SIM card X performs PS data transmission. However, as the number of SIM cards that need to interrupt the time period for performing PS data transmission (eg, shown as time period TP1 ) increases, the throughput of PS data transmission and the success rate of receiving MT calls may decrease. Therefore, the present invention provides an intelligent method of prioritizing subscriber identity cards in order to provide optimal communication services.

According to an embodiment of the present invention, the subscriber identity cards installed on the communication device 100 can be prioritized according to their individual profiles. The user of the communication device 100 can select or assign the above-mentioned individual information through the user interface (UserInterface, UI) and store it in the storage device 106, or the above-mentioned individual information can be stored in the priority basic file (ElementaryFile, EF) of the user identification card to define, or whatever. The above individual information may include card-based priority information or slot-based priority information. According to an embodiment of the present invention, the card-based priority information may contain information on the priority assigned to the corresponding subscriber identification card. For example, a user may select or assign a priority to a subscriber identity card and store the card-based priority information in the storage device 106 or in the EF of the subscriber identity card. According to another embodiment of the present invention, the slot-based priority information may contain information about the priority assigned to the slot. For example, a user can assign a priority to each slot. Once the SIM card is inserted into the slot, the priority of allocating the slot is assigned to the SIM card inserted into the slot. In many embodiments of the present invention, the above-mentioned individual information may further include information on the ratio of the number of subscriber identification cards that can be assigned different priorities. For example, the user can set the ratio of STANDBY_HIGH:STANDBY_LOW:SLEEP to 2:2:1 for a communication device including 5 SIM cards. Note that for the example of slot-based priority assignment, different SIM cards inserted into the same slot may be assigned the same priority. Therefore, the card-based priority information individual information and the slot-based priority information individual information may have different priority assignment results.

According to the first aspect of the present invention, there may be three priority levels, including STANDBY_HIGH, STANDBY_LOW, SLEEP. A subscriber identity card assigned STANDBY_HIGH priority can listen to paging messages, and can enjoy the authorization of the ability to receive calls at any time except when another subscriber identity card needs to establish a dedicated circuit switched (Circuit Switch, CS) connection. In other words, even when a SIM card is in packet transfer mode and/or the SIM card has established a PS connection with the wireless network to perform data transfer, the SIM card assigned STANDBY_HIGH priority can still enter the above-mentioned "virtual idle mode" and use the interrupted period to perform any tasks that can be performed in normal idle mode over the shared radio 104. Since paging messages can be received in virtual idle mode, this SIM card can receive MT calls at any time unless another SIM card needs to establish a dedicated CS connection. Therefore, according to various embodiments of the present invention, even if another SIM card is performing PS data transmission, the communication status of the SIM card assigned STANDBY_HIGH priority can still be "MTCapable", where "MTCapable" means that the SIM card is capable of Receive MT calls.

A SIM assigned STANDBY_LOW priority may listen to paging messages and may be granted the ability to receive calls at any time except when another SIM needs to establish a dedicated CS or PS connection. In other words, when a SIM is in packet transfer mode and/or the SIM card has established a PS connection with the wireless network for data transfer, or a CS connection with another party for voice, video or data Subscriber Identity Cards assigned STANDBY_LOW priority can go into "airplane mode" when calling. In "airplane mode", turn off the protocol stack corresponding to the subscriber identity card, and suspend the sending and receiving functions corresponding to the subscriber identity card. Therefore, the SIM card cannot perform any tasks performed in normal idle mode. In addition, the subscriber identity card may be located outside the coverage area of the cell and no service is available. Therefore, according to various embodiments of the present invention, when another subscriber identity card needs to establish a dedicated CS or PS connection, the communication status of the subscriber identity card assigned STANDBY_LOW priority is "MTDisable", "MTDisable" means that the subscriber identity card cannot To receive MT calls, therefore, the SIM card becomes incapable of receiving any MT calls during CS or PS data transmission performed by another SIM card.

Subscriber identification cards assigned SLEEP priority can enter "airplane mode" by default and can only be activated when the user of the communication device 100 places an MO call or data transmission request. Therefore, according to various embodiments of the present invention, unless activated by the user, the subscriber identity card is always in an inactive state. Therefore, the communication status of the subscriber identity card assigned the SLEEP priority can always be "MTDisable". Once a SLEEP priority-assigned subscriber identity card is activated for establishing a dedicated PS or CS connection, after the PS or CS connection is disconnected, the subscriber identity card may return to "airplane mode" and become "MTDisable".

According to the second aspect of the present invention, there may be two priority levels, including CALL_PREFER and DATA_PREFER. For Subscriber Identity Cards assigned CALL_PREFER priority, receiving calls has a higher priority than performing data transmissions. Therefore, according to an embodiment of the present invention, when another SIM card is performing PS data transmission, the communication status of the SIM card assigned the priority of CALL_PREFER may be "MTCapable".

On the other hand, for a subscriber identity card assigned a DATA_PREFER priority, the priority of performing data transmission is higher than that of receiving a call. Therefore, when another SIM needs to establish a dedicated CS or PS connection, that SIM cannot listen to paging messages, and when another SIM has to establish a CS or PS connection, the SIM assigned DATA_PREFER priority Can be "MTDisable".

According to an embodiment of the present invention, the processor 105 can assign the priority of each SIM card according to the stored individual information, and determine the communication state of the SIM card in a normal standby state according to the assigned priority. FIG. 4 shows a flowchart of a method for prioritizing a plurality of subscriber identification cards according to an embodiment of the present invention. In step S402, after the power of the communication device 100 is turned on, the processor 105 may obtain individual information corresponding to a plurality of subscriber identification cards, and assign a priority to each subscriber identification card according to the individual information. Next, in step S404, the processor 105 may determine the communication status of each subscriber identity card according to the corresponding priority. It should be noted that the priority assigned to each SIM card can be stored in the storage device 106 for later use. In order to simplify the description of the present invention and understand the content of the present invention more clearly, in the following embodiments, the communication device 100 including four subscriber identification cards is taken as an example. For the sake of brevity, the four subscriber identification cards are marked as SIM1, SIM2, SIM3, and SIM4. It is worth noting that, as mentioned above, the subscriber identity cards 101-1, 101-2, ..., 101-N can be SIM cards, USIM cards, RUIM cards, CSIM cards or others, and the number of subscriber identity cards does not vary. limited to certain values. Therefore, the present invention is not limited to the above-described embodiments. Table 1 is an example of priority levels assigned to a plurality of subscriber identity cards according to the first aspect of the present invention.

Subscriber Identification Card assigned priority SIM 1 STANDBY_HIGH SIM 2 STANDBY_HIGH SIM 3 STANDBY_LOW SIM 4 SLEEP

Table 1: Example of priority levels assigned to subscriber identity cards

According to an embodiment of the present invention, when no CS or PS connection is established, the processor 105 may also determine the communication status of each SIM (for example, "MTCapable" or "MTDisable") according to the corresponding priority. Table 2 is an example of the communication status assigned to each subscriber identity card in the normal standby status according to the first aspect of the present invention.

Subscriber Identification Card communication status SIM 1 MT Capable SIM 2 MT Capable SIM 3 MT Capable SIM 4 MT Disable

Table 2: Example of Communication Status for Each Subscriber Identity Card

According to an embodiment of the present invention, when one of the subscriber identity cards needs to perform data transmission through the radio transceiver module 104, since the communication device 100 must exit the normal standby state and perform data transmission, the processor 105 according to the assigned priority It is possible to further adjust the communication status of other subscriber identification cards except for the subscriber identification card that needs to perform data transmission, and determine whether to use the radio transceiver module 104 to listen to at least one address of other subscriber identification cards during the data transmission period according to the corresponding communication status. call message.

In the embodiment of the present invention, the processor 105 may determine the communication status of other subscriber identity cards according to the priorities assigned to other subscriber identity cards. Assume that in the embodiment, the subscriber identity card SIM1 needs to perform data transmission through the radio transceiver module 104 . Table 3 is an example of the communication status of other subscriber identity cards based on the assigned priorities shown in Table 1 according to this embodiment of the present invention.

Table 3: Example of communication status of other SIM cards when SIM1 needs to perform data transmission through the radio transceiver module

As shown in Table 3, because SIM2 is assigned STANDBY_HIGH priority, the communication status of SIM2 is MTCapable, and when SIM1 performs data transmission through the radio transceiver module 104, SIM2 can receive incoming calls. Therefore, the processor 105 can take time from the data transmission period of SIM1 and use the radio module 104 to listen for the paging message of SIM2 as shown in FIG. 3 . For example, during the data transmission period of SIM1, the processor 105 may temporarily suspend the data transmission of SIM1. After receiving the paging message from SIM2, the processor 105 can return the use right of the radio transceiver module 104 to SIM1, so as to resume the suspended data transmission of SIM1.

On the contrary, because the priorities assigned to SIM3 and SIM4 are STANDBY_LOW and SLEEP respectively, the communication status of SIM3 and SIM4 is MTDisable, and when SIM1 performs data transmission through the radio transceiver module 104, SIM3 and SIM4 cannot receive incoming calls. Therefore, during the data transmission period of SIM1, the processor 105 cannot use the radio transceiver module 104 to listen to the paging messages of SIM3 and SIM4. In many embodiments, during the data transmission period of SIM1, the processor 105 may further suspend the sending and receiving functions corresponding to SIM3 and SIM4. Therefore, during the data transmission period of SIM1, SIM3 and SIM4 may enter "airplane mode" and the service is unavailable.

FIG. 5 shows a schematic diagram of a method for scheduling radio activities of a subscriber identity card according to an embodiment of the present invention. As shown in Figure 5, as step S502, under normal stand-by state, processor 105 can use radio transceiver module 104 to listen to the subscriber identification card (such as SIM1, SIM2 and SIM3 shown in table 2) that communication state is " MTCapable " in turn. paging message. Next, as shown in step S504, the processor 105 may periodically or aperiodically check whether there is a PS connection established by the subscriber identity card for performing data transmission. When there is a subscriber identity card that has established a PS connection for performing data transmission, in step S506, the processor 105 may further determine whether the priority of other subscriber identity cards is STANDBY_HIGH. If yes, as shown in step S508, the communication state of the subscriber identity card remains at "MTCapable", therefore, the processor 105 can still use the radio transceiver module 104 to listen to the subscriber identity card during the data transmission period of another subscriber identity card. Card's paging message. If not, as shown in step S510, the communication state of the subscriber identity card is set to be "MTDisable", and the processor 105 can stop using the radio transceiver module 104 to listen to the subscriber identity card during another subscriber identity card execution data transmission period. paging message. In many embodiments, during the data transmission period, the processor 105 may further suspend the sending and receiving functions of the SIM card whose communication state is "MTDisable". After step S508 or step S510, as shown in step S512, the processor may further determine whether the priority levels of other subscriber identification cards have all been checked. If not, return to step S506 to determine whether the priority of the next other subscriber identity card is STANDBY_HIGH.

According to the second aspect of the present invention, as described above, the priority assigned to each subscriber identity card may also be determined based on whether receiving a call or performing data transmission is prioritized. Table 4 is another example of priorities assigned to subscriber identity cards according to the second aspect of the present invention.

Subscriber Identification Card assigned priority SIM 1 CALL_PREFER SIM 2 DATA_PREFER SIM 3 CALL_PREFER SIM 4 DATA_PREFER

Table 4: Another example of priority levels assigned to each SIM card

Based on the priorities shown in Table 4, according to an embodiment of the present invention, when one of the subscriber identity cards needs to perform data transmission through the radio transceiver module 104, it can be allocated to other corresponding subscriber identity cards as shown in Table 5. The priority is used to determine the corresponding communication status of other SIM cards.

Table 5: Communication status of other SIM cards when one SIM card needs to perform data transfer

As shown in Table 5, since the priority assigned to SIM1 and SIM3 is CALL_PREFER, when another SIM needs to perform data transmission, the communication status of SIM1 and SIM3 can be MTCapable. On the other hand, because the priority of SIM2 and SIM4 is DATA_PREFER, when another SIM card needs to perform data transmission, the communication state of SIM2 and SIM4 may become MTDisable.

Table 6: Communication status of other SIM cards when one SIM card needs to perform data transfer

Based on the priorities shown in Table 4, according to another embodiment of the present invention, the processor 105 may also determine the communication status of other subscriber identity cards according to the priority assigned to one of the subscriber identity cards, wherein the above-mentioned subscriber identity card The card needs to perform the data transfer. Table 6 shows another example of communication states of other subscriber identity cards determined when one of the subscriber identity cards needs to perform data transmission according to another embodiment of the present invention.

As shown in Table 6, because the priority assigned to SIM1 and SIM3 is CALL_PREFER, when SIM1 or SIM3 needs to perform data transmission, the communication status of SIM2, SIM3, SIM4 or SIM1, SIM2, SIM4 can be MTCapable. In other words, because the priority assigned to SIM2 and SIM4 is DATA_PREFER, when SIM2 or SIM4 needs to perform data transmission, the communication status of SIM1, SIM3, SIM4 or SIM1, SIM2, SIM3 may change to MTDisable.

Based on the priorities shown in Table 4, according to another embodiment of the present invention, processor 105 can also determine the communication status of other subscriber identity cards according to two priorities, wherein the above two priorities are assigned to one of the needs The SIM card performing the data transfer and the priority assigned to the corresponding other SIM cards. Table 7 is another example of the communication status of other subscriber identity cards determined when one subscriber identity card needs to perform data transmission according to another embodiment of the present invention.

Table 7: Communication status of other SIM cards when one SIM card needs to perform data transfer

In an embodiment, only when the priorities assigned to the subscriber identity card that needs to perform data transmission and the corresponding other subscriber identity cards are both CALL_PREFER, the communication status of the other subscriber identity cards is MTCapable. As shown in Table 7, since the priority assigned to SIM1 and SIM3 is CALL_PREFER, when SIM1 or SIM3 needs to perform data transmission, the communication status of other SIM3 or other SIM1 can be MTCapable. Otherwise, the communication state of other SIM cards may be MTDisable.

6A and 6B are schematic diagrams showing a method for prioritizing radio activity of a subscriber identity card when a subscriber identity card needs to perform data transmission according to the first embodiment of the present invention. In an embodiment, each SIM is assigned one of three priorities, including STANDBY_HIGH, STANDBY_LOW and SLEEP. As shown in step S602, after the processor 105 receives a data transmission request for data transmission of a subscriber identity card (hereinafter referred to as SIMX), as shown in step S604, the processor 105 can obtain the user ID assigned to the subscriber identity card from the storage device 106. The priority of the card.
