In addition, it is also responsible for processing incoming services and/or events at various protocol layers (eg, non-access stratum NAS, access stratum AS, physical layer PHY) in accordance with the agreed communication protocol. The communication protocol may be any existing wireless communication system, such as GSM, UMTS, LTE, LTE-A, etc. or a protocol in which a wireless communication system may occur in the future. Although the technical problems and solutions to be solved by the embodiments of the present invention will be mainly described herein by taking a dual-mode dual-card mobile terminal using the GSM and UMTS mobile communication systems as an example, it should be understood that the embodiments of the present invention are equally applicable to There are similar problems with dual-mode dual-card mobile terminals or multi-mode multi-card (such as three-mode three-card) mobile terminals using other communication systems.

Taking a dual-mode dual-card mobile terminal using GSM and UMTS mobile communication systems as an example, the baseband processing chip 101 may include processors for each GSM and UMTS protocol layer, and handle the services and/or events arriving at each layer of each card. . However, in order to reduce the cost of the mobile phone to facilitate the promotion of the smart machine, reduce the size of the mobile phone, so as to facilitate the user to carry and improve the user experience, reduce the radiation, etc., the hardware composition of the dual-mode dual-card mobile terminal may include only one set of radio frequency modes. A group, such as the 2G/UMTS radio frequency module 102 shared by GSM and UMTS, as exemplified in FIG. In this case, how to ensure that the two cards use shared resources without conflict to ensure two It is an urgent problem to solve the problem that the card can stand by and start the business independently. It should be noted that FIG. 1 is only one example of a multi-mode multi-card terminal, and for a terminal with more than two cards, the problem of this service and/or event conflict will be more prominent. The following description of embodiments of the invention will apply to any multi-mode multi-card (such as three-mode three-card) terminal, including but not limited to dual-mode dual-card terminals.

In order to solve this problem, in one embodiment of the present invention, a A method of processing a service conflict in a multimode multi-card terminal, the method comprising: performing at least one of a non-access stratum, an access stratum, and a physical layer of each card in the multi-mode multi-card terminal: Determining services and/or events in which conflicts may occur; setting respective priorities of the services and/or events; and caching or executing the services and/or events in accordance with the prioritization and predetermined rules.

FIG. 2 shows only one given communication protocol layer as an example according to the present invention. A schematic flow chart of a method for detecting and processing a business conflict performed by an embodiment, but it is worth noting that the method illustrated in the example of FIG. 2 can be applied to a multimode multi-card (such as a dual mode dual card, a three mode three card, etc. Any of the non-access stratum, access stratum, and physical layer of each card of the terminal. In one example, the flow shown in FIG. 2 is performed by the baseband processing wafer 101 or the related circuit shown in FIG.

For a given layer of a given card, the new service and/or event arrives first after In step 201, it is determined that a conflicting service and/or event may occur. According to an embodiment of the invention, the determining comprises determining the type of service and/or event request that is arriving. According to still another embodiment of the present invention, the determining further comprises detecting a service and/or an event that the corresponding layer of another card is executing or is about to perform when the program is executing a new service and/or event, and based on the detection result Identify businesses and/or events that may be in conflict. In some embodiments of the invention, wherein The detection includes detecting common information in a corresponding layer of another card to obtain a service and/or event that is being executed or is about to be executed.

If the given layer is a non-access stratum NAS, it may lead to resource conflicts in the business and / or event, that is, services and/or events that cannot be simultaneously performed by non-access stratum NAS of multiple cards, including: circuit-switched voice service/location area update/routing area update/attach/de-attach, packet-switched data service, Background search. If a given layer is an access layer, services and/or events that may cause resource conflicts include: radio resource control connection establishment, community selection and reselection, and background search. If a given layer is a physical layer, services and/or events that may cause resource conflicts include: transmitting and receiving on the same radio resource, receiving paging indication, co-frequency/inter-frequency measurement, different system measurement, and search ( With re-selection) and so on.

If no conflict is detected in step 201, it can be executed directly at a given layer. The new service and/or event, step 211 is performed, and then the conflict detection and arbitration process ends. If a conflict is detected, the process proceeds to step 202.

At step 202, a given layer of a given card is identified as a possible conflicting industry Set priorities and/or events. The prioritization setting will take into account the QoS requirements of each service and/or event or the impact of the service and/or delay on performance, and the like. The services and/or events that participate in the prioritization may be different due to different services and/or events that may be in conflict at each layer, and the priorities may be set differently. As a special embodiment of the present invention, in consideration of the main services and/or events of each layer, a common priority order can be set as follows: Call Service (CS) service is given the highest priority because it is sensitive to delay. Set to 1A; LAU/RAU, ATTACH/DETACH and other signaling processes enjoy the same priority as voice services; the next is Packet Service (PS) service, set to 1B; community selection and community Reselection, with the same priority, set to 2; same frequency / inter-frequency measurement, set to 3A, different system measurement, set to 3B; and background search PLMN is set to the lowest priority 4. In this example, the order of priority order is from high to low, 1A>1B>2>3A>3B>4.

According to an embodiment of the present invention, the priority order may be that the determination may be Pre-sets of conflicting services and/or events, or during conflict handling, such as determining conflicts for conflicting traffic and/or events.

At step 203, the priority order and the pre-set according to step 202 are prompted. The rules cache or execute the services and/or events that may be in conflict.

According to an embodiment of the present invention, in the determination, a conflict may occur The predetermined rules are set before or during the service and/or event.

According to still another embodiment of the present invention, the predetermined rule includes the following rules At least one of the rules: Rule 1: If a card detects that the corresponding layer of any other card is doing the same priority business and/or event when the project is executing a new service and/or event, the cache is caused to be cached. The new service and/or event executed by the plan; Rule 2: If a new service and/or event is scheduled to be executed, the corresponding layer of any other card is detected to be doing a higher priority service and And/or an event, causing a new service and/or event to be cached to be executed, or discarding the plan to execute a new service and/or event and reverting to the plan to execute a new service and/or event Previous state; rule 3: If a card detects that the corresponding layer of any other card is doing a higher priority service and/or event while the project is executing a new service and/or event, then the cache is prompted Describe the new business and/or events performed by the project and indicate the Save, or discard the plan to perform new services and/or events and revert to the state prior to the program executing new services and/or events; Rule 4: If a card is executing a new service and/or Or event, detecting that the corresponding layer of any other card is performing lower priority services and/or events, notifying the corresponding layer of the other card to interrupt and buffering the lower priority that is being executed Business and/or events and cause new services and/or events to be executed by the program; Rule 5: If a card has services and/or events that are cached and received from the corresponding layer of any other card The cached service and/or event is executed to include a notification that the indication of the cached service and/or event can be executed; rule 6: if the service and/or event is executed, the correspondence to another card The layer sends a notification that the corresponding layer of the other card can perform an indication of the cached service and/or event; rule 7: if one card service and/or event is executed, then another Corresponding layer of the card Sending a notification and updating the sharing information, the notification including an indication that the corresponding layer of the other card can perform the cached service and/or event; the update sharing information includes information from the executed event The common belief is cleared; rule 8: if a card receives a new service and/or event during the execution of the service and/or event, compares the priority of the received new service and/or event with another Cards correspond to the priority order of the services and/or events cached by the layer; and if the new services and/or events received are prioritized higher than the priority of the services and/or events cached by the corresponding card of the other card , after the current service and/or event execution ends, continue to execute the received new service and/or event without notifying the other card; and if the new service and/or event received is superior First, the order is lower than or equal to the priority order of the services and/or events cached by the corresponding layer of the other card, and the other card is notified after the current service and/or event is executed; Rule 9: If a card During the execution of the service and/or event, a notification is received from the corresponding layer of the other card that includes an indication to interrupt the currently executing service and/or event, and the currently executed service and/or event is interrupted and cached.

Rule 1-4 is about processing new arrivals in accordance with the set priorities. Rules for services and/or events; rules 5 are rules for when cached services and/or events are executed; rules 6-7 are rules for processing after services and/or events are executed, while rules 8-9 are for services and / or other triggered processing rules that occur during event execution. In the embodiment of the present invention, the above multiple rules may be selected and used in combination. For example, if a given layer of the first card detects that the peer of the second card is doing a higher priority service and/or event while the plan is executing a new service and/or event, then The layer cache plan of the first card plans to perform new services and/or events until the second card first executes the high priority service and/or the event informs the corresponding layer of the first card to process the cached service And/or an event, or the layer of the first card discards the plan to perform a new service and/or event and reverts to the original state. In another example, when the first card receives a service and/or event request, the MA first queries the second card whether there is currently a service and/or event, and if so, obtains its business and/or event priority. Discriminate the conflict and determine the priority of the business and/or event to be initiated by the card. If it is a lower priority, it is not necessary to notify the second card to suspend all the services and/or events being executed, but The common information is set by the MA; next, if the second card receives a service and/or event request, the MA will also query the current service and/or event priority of the first card, if the second card is found. Business and / or events and the first fixture When there is equal priority, or lower priority than the first one, then the service and/or event is cached first; after the first card is finished, the second card is notified to process the cached service and/or event, and at the same time Update shared information.

For a given layer, the conflict detection and arbitration process ends at step 204. It should be noted, however, that for the sake of clarity, Figure 2 only gives an example of the processing flow at a given layer, so step 204 is only the end of the conflict detection and arbitration process for this given layer, rather than the end of the entire conflict detection arbitration process. . If the specified layer is not the last layer to perform conflict processing, the process will proceed to the next layer, and this will be described later in connection with FIG.

Additionally, it should be understood that although the exemplary flowcharts illustrate exemplary execution steps However, in different embodiments, the order of execution of the steps may be different from the exemplary order. For example, in some embodiments, step 202 may precede other steps, ie, prioritize the order of precedence.

The following assumes that a given layer is an access layer, as an example to introduce one according to the present invention. An exemplary method for an implementation access layer to resolve a business conflict. In this example, a dual-card dual-mode terminal is taken as an example. Assume that the access layer of the first card receives the voice service establishment request sent by the non-access stratum. Since it has the highest priority 1A, the first card needs to notify the second card to interrupt and suspend all currently executing. A low priority service and/or event to be executed, which is lower than the service level and/or event. After the second card completes the suspending process, the first card starts to perform the GRR/RRC connection establishment request event, and requests the circuit to exchange domain voice services to the network. In the process, the first card access layer is absolutely enjoyed. Shared resources (RF, antenna, baseband processing unit, etc.). After the first card service ends, the first card access layer detects whether there are still other services and/or event requests with higher priority than the service and/or event cached by the second card, if If the first card continues to execute other services and/or events with higher priority, the second card is not notified to be restored; otherwise, the second card is notified to resume the state before being cached, and the cached service is executed. And / or events. The community re-election assessment is stopped during the period when the second card's services and/or events are suspended; in addition, during this period, if a non-access stratum sends a search request or a public land mobile network (PLMN) Search for requests, cache first, and then restore the cached business and/or events.

According to an embodiment of the present invention, the access layer resolves a service conflict Including: if the access layer of the first card is ready to start the search/reselection/PLMN search, the shared information of the first card and the second card access layer needs to be updated, and then the search is started. The second card stops the community reselection measurement evaluation; in addition, if the second card receives the search/PLMN search sent by the non-access layer, it needs to query the sharing of the first card and the second card access layer. Information, if the first card is performing a search, the above event is cached; after the first card ends the search, the shared information is updated, and the second card is notified; the second card is restarted for re-measurement measurement evaluation, or Performing cached search and other events, and updating the shared information; during the first card search, if the second card receives the GRR/RRC connection establishment request from the non-access layer, the second card will notify The first card hangs, the first card will interrupt the current search event, and the shared information will be updated; after the second card is finished, the first card will perform the search again.

The above is a conflict resolution embodiment of the access layer. For the non-access stratum and the physical layer, The conflict resolution embodiment is similar to the access layer, and therefore will not be described here.

According to one embodiment of the invention, the operation as shown in Figure 2 is performed by the service and / Or the layer at which the event arrives begins, and all layers involved in the conflict processing are executed in tandem in order from the upper layer to the lower layer.

Figure 3 illustrates a multi-mode multi-card terminal in accordance with one embodiment of the present invention. Schematic flow chart of a method for detecting and processing a service conflict by a communication protocol layer. In this example, for the sake of simplicity, only the operation of one card is shown. And it is assumed that an embodiment of collision processing is performed at each of the non-access stratum, the access stratum, and the physical layer. As shown, in the exemplary embodiment, the collision detection and processing operations as described in FIG. 2 are performed in each layer string in order from the upper layer to the lower layer.

First, in step 301, non-access stratum detection is performed to determine that a collision may occur. The service and/or event; if there is a conflict, proceed to step 302, where the non-access stratum service and/or event conflict is processed according to the step (202-203) of FIG. 2, and then proceeds to step 303; If there is a conflict, the non-access stratum service and/or event is directly executed in step 311, and then proceeds to step 303.

In step 303, access layer detection is performed to determine a service that may be in conflict. And/or event; if there is a conflict, proceed to step 304, and likewise, in step 304, process the access layer service and/or event conflict according to step (202-203) of FIG. 2, and then proceed to step 305; if not In the event of a conflict, access layer services and/or events are performed directly in step 312, and then proceeds to step 305.

Similarly, in step 305, physical layer detection is performed to determine that a rush may occur. a sudden service and/or event; if there is a conflict, proceed to step 306, where the physical layer service and/or event conflict is processed in accordance with the steps (202-203) of FIG. 2, and then ends at step 307; if not In the event of a conflict, physical layer services and/or events are performed directly in step 313 and then ended in step 307.

It should be noted that although in this exemplary embodiment, it is assumed that at the non-access stratum, Each of the access layer and the physical layer performs collision processing, but in other embodiments, the method steps described above can also be implemented only at some of the layers. In addition, each of the multimode multi-cards (such as dual-mode dual-card, three-mode three-card, etc.) can adopt this method.

Embodiments of the invention also include corresponding apparatus capable of implementing the above methods. 4 is a schematic block diagram of an exemplary apparatus 400 for implementing detection and resolution of multi-mode multi-card mobile terminal traffic collisions, in accordance with one embodiment of the present invention.

As shown in FIG. 4, the exemplary device 400 includes a set of MA modules 421, wherein A plurality of MA modules (eg, 421-1, 421-2, 421-3, 421-4, 421-5, 421-6) are respectively distributed in the non-access stratum NAS mode for each card of the multi-card Groups 401 and 411, access layer AS modules 402 and 412, and physical PHY control layer modules 403 and 413; wherein each of the above modules (401, 402, 403, 411, 412, 413) supports multimode communication protocols For example, support for GSM/UMTS communication protocols. Although for the sake of simplicity and clarity, only the modules for the two cards are given in the example of FIG. 4, and the modules for other more cards are omitted, it should be understood that the present invention is not limited to the two cards shown. Implementation.

The non-access stratum modules 401 and 411 in FIG. 4 are respectively used to execute the first sheet The operation of the non-access stratum of the card and the second card. Since each of the modules 401 and 411 is assumed to support GSM/UMTS dual mode, each of the two cards can be a GSM or UMTS mode card. In accordance with an embodiment of the present invention, the MA modules 421-1, 421-4 in the modules 401 and 411 are configured to perform operations for determining services and/or events in which conflicts may occur; setting the services and/or Or a corresponding priority order of events; and caching or executing the services and/or events in accordance with the prioritization and predetermined rules.

According to an embodiment of the present invention, the MA module 421-1 can be further used. Notifying the corresponding layer of another card to interrupt and cache the services and/or events it is performing at the beginning of the high priority service and/or event execution, and/or notifying another after the execution of the business and/or event is completed The card begins to execute its cached business and/or events.

According to still another embodiment of the present invention, the MA module 421-1 may further Used to share information about the cached service and/or event when low priority services and/or events arrive and cache services and/or events, and/or for performing the business and/or event and notifying another The card updates the sharing information to clear information about the executed services and/or events from the shared information.

If new services and/or events are on the first card's non-access stratum (NAS) The MA 421-1 module in 401 performs operations to determine services and/or events that may be in conflict, including determining the type of service and/or event, in accordance with an embodiment of the present invention. According to still another embodiment, the method further includes detecting whether a non-access layer of the corresponding another card has a conflict, and determining according to the detection result. This will require 401 and 411 to communicate. In one embodiment, the detecting includes detecting the shared information in the MA module 421-4 in the other card corresponding layer 411 to obtain the services and/or events being executed or to be performed.

For non-access stratum, business and/or event packages that may result in resource conflicts Including: circuit switched voice service / location area update / routing area update / attach / detach, packet switched data service, background search, and the order listed above is the priority of the MA module 421-1 set from high to low An example of the order.

After the priority is set, the 401 MA module will be further based on the predetermined rules. The processing of conflicting traffic and/or events with the determined priority order is determined, such as caching or execution. This rule definition is also done by the MA module 421-1 of 401. And predetermined rules An example (rules 1-9) has been introduced in the description about FIG. 2 and will not be described again here.

According to an embodiment of the invention, performing the service and/or event is further included in Before the execution, the corresponding layer module 411 of the other card is notified to interrupt and cache the business and/or event that it is executing, and then the 401 module executes the new service and/or event executed by the plan; until 401 executes the high priority service And/or after the event, the 411 module is notified by its MA module 421-1 to resume performing lower priority services and/or events, for example, to notify the MA 421-4 in the module 411, and then the MA 421-4 motivates Module 411 interrupts and caches traffic and/or events.

Similarly, access layer (AS) modules 402 and 412 are used to perform The operation of the access layer of the first card and the second card. And in one embodiment each of modules 402 and 412 supports, for example, GSM/UMTS dual mode, so each card in the dual card can be a GSM or UMTS mode card. In accordance with an embodiment of the present invention, there is also one MA module 421-2 and 421-5 in modules 402 and 412, the operations performed at the access layer and those described with respect to MA 421-1 and MA 421-4. The operation is similar. The difference is that services and/or events in the access layer that may cause resource conflicts may be different from services and/or events in the non-access stratum. For example, conflicting services and/or events that may occur at the access layer mainly include : RRC/GRR connection establishment, community selection and reselection, background search, but the conflict processing method steps are consistent with the non-access layer.

Similarly, physical (PHY) control layer modules 403 and 413 are used to perform the needles, respectively. For the operation of the physical control layer of the first card and the second card, the physical control layer referred to herein can be regarded as a part of the physical layer. In one embodiment, each of the modules 403 and 413 supports GSM/UMTS dual mode, so each card in the dual card can be a GSM or UMTS mode card. In accordance with an embodiment of the present invention, there is also one MA module 421-3, 421-6 in each of the physical control layer modules 403 and 413, which may enter conflicting services and/or events that may occur at the physical layer. Evaluation, determination and arbitration. This operation is similar to the above operations regarding the non-access stratum and the access stratum, and therefore will not be described again. The difference is that the physical layer may cause the resource conflicting service and/or event to be different from the non-access stratum. For example, the main conflicting service and/or event includes: sending and receiving on the same radio resource, receiving paging indication, Same frequency/inter-frequency measurement, different system measurement, search network (including reselection), etc.

Since the collision of the physical layer after the MA module of 403 and 413 is punched out, Thus, the dual mode dual card terminal requires only one physical and RF module to handle the services and/or events from the two cards, thereby reducing the cost and size of the end product.

It should be noted that although the MA module of each layer of each card is shown in Figure 4 As a separate module, in a different embodiment, the combination of multiple MA modules can also be implemented by a single module. For example, the MA module in the 401 and 411 of the NAS layer can be implemented by a single module. 421-1, 421-4, or the functions of all MA module groups 421 can be implemented by a single module. Also, in some embodiments, each of the MA modules of FIG. 4, as well as the functionality of each of the other modules, may also be distributed across multiple modules.
