Description

Method, device, DH and NFCC for conflict resolution of radio frequency interface expansion

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method and device for conflict resolution of radio frequency interface extension, DH and NFCC.

Background technique

With the development of communication technologies, especially the popularization of Near Field Communication (NFC) technology, NFC terminals can implement short-range communication based on Radio Frequency Identification (RFID) technology.

During the short-range communication between the NFC terminals, the host controller (DH) of the local NFC terminal can pass through a radio interface (RF Interface) of the NFC terminal, such as Frame RF Interface, ISO-DEP RF Interface, NFC-DEP RF Interface, or NDEF RF Interface, and a corresponding RF protocol such as T1T protocol, T2T protocol, T3T protocol, T5T protocol, ISO-DEP protocol, or NFC-DEP protocol Communication between the peer NFC terminals, and one or more RF Interface Extensions can be run on one RF interface. The RF interface extension can be triggered by the DH through the NCI (NFC Controller Interface) protocol. The NFC Controller (NFC) is turned on to allow the NFCC to implement more functions.

In order to enable the NFCC to open a radio interface extension, the DH needs to configure the NFCC to perform the parameters required for the expansion of the radio interface. As the radio interface expansion increases, the possibility of collision between these radio interface extensions is greater. For example, there are conflicts between the parameters corresponding to different RF interface extensions. Therefore, when DH is enabled to open multiple radio interface extensions, it may cause an open failure due to a conflict between them, or a conflict occurs when the corresponding function is executed after being turned on, resulting in a decrease in communication efficiency.

The singular forms "a", "the", "the" and "the" . It should also be understood that the term "and/or" as used herein refers to and encompasses any, or all possible combinations of one or more of the associated listed items. Depending on the context, "when" can be interpreted as "in response to determining" or "in response to detecting" as used herein.

The embodiment of the present invention can be used for an NFC terminal. As shown in FIG. 1, the NFC terminal is provided with a main controller DH and a near field communication controller NFCC. There is at least one radio frequency interface between the DH and the NFCC, wherein one radio frequency interface corresponds to one or more radio frequency interface extensions. In the embodiment of the present invention, the DH may be responsible for the management of the NFCC, such as: NFCC initialization, configuration, and power management; the NFCC may be responsible for physical data transmission through the radio frequency interface and the antenna; the DH and the NFCC may communicate through the NCI protocol, where The NCI protocol defines a radio frequency interface for communicating with the peer through some RF protocol. The NFC terminal communicates. It should be noted that, according to the NCI protocol, one radio frequency interface extension can be used for multiple radio frequency interfaces, and one radio frequency interface can also support multiple radio frequency interface extensions. The RF interface extension is a function extension of the RF interface. That is, the DH can trigger a group of tasks or a function on the NFCC through an NCI command (such as the open command RF_INTF_EXT_START_CMD). Of course, the DH can also pass the NCI command (such as the stop command RF_INTF_EXT_STOP_CMD). Stop the NFCC from continuing to perform this set of tasks or this function. In the embodiment of the present invention, the NFC terminal may be any NFC-enabled terminal, such as a mobile phone, a mobile computer, a tablet computer, a personal digital assistant (PDA), or a wearable device (Wearable Device).

It should be noted that the above DH is a term used in the NCI specification developed by the NFC Forum, and can correspond to a host controller interface (HCI, Host Controller Interface) developed by the European Telecommunication Standards Institute (ETSI). The terminal host (Terminal Host) in the specification; in addition, the management entity (ME, Managing Entity) in the specification developed by the Global Platform International Standards Organization (GP) can also be called DH if it is implemented on the Terminal Host. To manage the host (MH, Managing Host). The above NFCC is a term used in the NCI specification developed by the NFC Forum to correspond to the non-contact front end (CLF, Contactless Front-end) in the HCI specification developed by the European Telecommunication Standards Institute (ETSI). At this time, the host controller (Host Controller) in the HCI specification is implemented on the NFCC.

The embodiment of the invention provides a conflict resolution method for the radio frequency interface extension, which is performed by the main controller DH. As shown in FIG. 2, the method includes:

101. The main controller DH acquires conflict information.

The conflict information is used to indicate that there is a conflict between at least two radio frequency interface extensions corresponding to the at least one radio frequency interface.

In the embodiment of the present invention, the conflict information may be directly sent by the NFCC, and may also be generated by the DH according to the radio interface extension information sent by the NFCC. The specific manner of obtaining the conflict information may be described in the following embodiments.

It should be noted that one RF interface extension conflicts with another RF interface extension. The reason is not specifically limited in the embodiment of the present invention, and may be that the NFCC performs a radio frequency interface extension separately from another radio frequency interface extension, and these parameters cannot be simultaneously configured to the NFCC; or one radio frequency interface extension and another The parameters of a radio interface extension need to be the same, but the values of the parameters are different. Alternatively, the version of the protocol that the NFCC performs when performing a radio interface extension is different from that of another radio interface. For example, an RF interface extension cannot be used. Execution on the current version of NFCC can only be performed on a higher version, while another RF interface extension can be performed on the current version; or one RF interface extension is the same as an attribute type of another RF interface extension, but The specific content of an attribute is different; or any other reason that may cause multiple RF interface extensions to be mutually exclusive and cannot be opened at the same time in NFCC.

In the embodiment of the present invention, the conflict information may be represented by a conflicting byte. As shown in Table 1, the conflicting byte is used to indicate conflict information of multiple radio interface extensions corresponding to one radio interface. Where b0 to b7 are used to represent 8 bits in 1 byte, each bit is used to indicate a radio interface extension, and the value X of a bit is used to indicate whether the radio interface extension corresponding to the bit is There is a conflict between the radio interface extensions corresponding to other bits, and X can be 0 or 1. For example, when the value X of any two or more bits is 1, it indicates that there is a conflict between the radio interface extensions corresponding to the bits, that is, the NFCC cannot simultaneously perform the functions corresponding to the extension of the radio interface.

Table I

For example, a radio frequency interface defined in the NCI protocol corresponds to four radio interface extensions e1, e2, e3, and e4, the b0 bit is used to indicate the radio interface extension e1, and the b1 bit is used to indicate the radio interface extension e2, b2. The bit is used to indicate the radio interface extension e3, and the b3 bit is used to indicate the radio interface extension e4. When the NFCC performs the functions corresponding to the radio interface expansion e1 and the radio interface extension e2, a conflict occurs, and when the NFCC performs the functions corresponding to the radio interface extension e2, the radio interface extension e3, and the radio interface extension e4, a conflict occurs. As shown in Table 2, in the conflict information Contains two conflicting bytes, collision byte 1 and collision byte 2. The value X of the b1 bit and the b0 bit in the collision byte 1 is 1, and the value X of the b3 bit, the b2 bit, and the b1 bit in the collision byte 2 is 1.

Table II

It should be noted that the manner in which the conflict information is displayed is not specifically limited in the embodiment of the present invention. One or more of the conflicting bytes in the embodiment may be used to list one or more sets of radio frequency interface extensions that conflict with each other. Of course, other methods may be used to describe whether there is a conflict between the radio interface extensions corresponding to a certain radio interface, for example, one or more non-conflicting bytes are used to list one or more sets of radio interface extensions that do not conflict with each other. Or use other forms to identify the presence or absence of conflicting RF interface extensions. Regardless of the method used to describe the conflict or non-conflict between the RF interface extensions corresponding to the RF interface, DH can use this information to ensure that it is turned on. There is no conflict between multiple RF interface extensions, or between the enabled RF interface extensions and the enabled RF interface extensions. Furthermore, the description of the conflict information is equally applicable to the following embodiments.

102. The DH determines, as a target radio frequency interface extension, at least one unopened radio frequency interface extension from the radio frequency interface extension corresponding to the activated radio frequency interface.

In the embodiment of the present invention, the activated radio frequency interface indicates that the radio interface is currently in an active state, and is one of the at least one radio frequency interface defined in the NCI protocol.

It should be noted that, in the foregoing step 101, the NFCC may send only the conflict information corresponding to the one or more radio frequency interfaces to the DH, as long as the conflict information corresponding to the activated radio frequency interface is included, This is not limited. Similarly, the NFCC may send the radio interface extension information corresponding to the one or more radio interfaces to the DH, and the DH may generate the activated radio interface corresponding to the radio interface extension information corresponding to the activated radio interface. The conflicting information is not limited in this embodiment of the present invention.

103. The DH starts at least one of the target radio interface extensions according to the conflict information. One.

When a radio interface is activated, DH can determine whether to enable the NFCC to open one or more radio interface extensions on the activated radio interface by sending an RF_INTF_EXT_START_CMD command to the NFCC based on the service requirements and/or the capabilities of the NFCC.

In step 102, the at least one un-opened radio interface extension can be determined as the target radio interface extension. When the target radio interface is extended to one, the radio interface extension corresponding to the activated radio interface can be extended, or even the radio interface. The extended priority case determines whether the target radio interface extension is turned on. For example, if there is no open RF interface extension, the target RF interface can be extended; if there is currently at least one enabled RF interface extension, and the target RF interface is extended and the enabled RF interface is extended. If there is no conflict, the target radio interface can be extended; if there is currently at least one enabled radio interface extension, and there is a conflict between the target radio interface extension and the opened radio interface extension, then Their priority order is further determined to determine whether to extend the target radio interface. When the target radio interface is extended to multiple ports, it is also possible to determine whether to open the target radio interface according to the opening condition of the radio interface extension corresponding to the activated radio interface, or even the priority of the extension of the radio interface. For one or more of the following, refer to the following embodiments for specific processing, and details are not described herein again.

The method for conflict resolution of the radio frequency interface extension is provided by the embodiment of the present invention. The main controller DH expands the target radio frequency interface according to the acquired conflict information and the target radio frequency interface extension determined from the radio interface extension corresponding to the activated radio interface. At least one of the extensions. The conflict information is used to indicate that there is a conflict between at least two radio interface extensions corresponding to the at least one radio interface. Compared with the prior art, at least one radio frequency interface extension is directly enabled by the screening of the radio frequency interface extension. In the embodiment of the present invention, at least one of the target radio frequency interface extensions can be enabled by the DH according to the conflict information, thereby avoiding the radio frequency. A conflict occurs when there is a conflict between interface extensions, or a conflict occurs when the corresponding function is executed after being turned on. Therefore, when multiple radio interface extensions are enabled, the DH reduces the probability of collision between at least two radio interface extensions that are in the on state after the radio interface expansion is enabled, thereby improving communication efficiency.

The method for obtaining the conflict information in the DH in the step 101 is different. In another implementation manner of the embodiment of the present invention, the manner of acquiring the conflict information may be specifically implemented as being obtained from the DH, or The initialization response message sent by the NFCC, the radio frequency interface activation notification message, the opening response message, or the opening notification message is obtained. Therefore, on the basis of the implementation as shown in FIG. 2, the implementation may be implemented as shown in FIG. 3, wherein the main controller DH of step 101 acquires conflict information, which may be specifically implemented as shown in FIG. Any step from step 1011 to step 1015:

1011. The DH receives the radio frequency interface extension information sent by the near field communication controller NFCC, and generates the conflict information.

At least one radio frequency interface exists between the DH and the NFCC, and one radio frequency interface corresponds to one or more radio frequency interface extensions; the radio frequency interface extension information is used to indicate that the radio frequency interface corresponding to the at least one radio frequency interface is extended. Type information. The radio frequency interface extension information includes type information for indicating the radio frequency interface extension corresponding to the at least one radio frequency interface (refer to the NCI protocol, which is not described in detail herein), and the information may pass the NCI response message defined in the NCI protocol. Or the NCI notification message (such as the initialization response message CORE_INIT_RSP) is obtained, and then the DH can use the information to generate corresponding conflict information for one of the radio frequency interfaces or each radio frequency interface. Of course, the DH can be developed according to the manufacturer of the NFC terminal when developing the NCI. Pre-set policies or rules use these received RF interface extensions to generate conflicting information.

1012. The DH acquires the conflict information of the stored system preset.

The collision information may be pre-configured to the DH by the manufacturer of the NFC terminal when developing the NFC controller interface NCI; of course, the storage may be performed by other means, for example, the DH saves the conflict information corresponding to a certain radio interface for the first time. To a certain storage area, you can directly obtain the conflict information from the storage area.

1013. The DH receives an initialization response message sent by the NFCC, and obtains the conflict information from the initialization response message.

According to the NCI protocol, an initialization response message is sent by the NFCC to the DH for feeding back the result of the NFCC initialization to the DH. In the initialization phase, the NFCC may report the conflict information to the DH by initializing the response message (such as the CORE_INIT_RSP command sent by the DH to the NFCC as shown in Table 3), and then the DH judges that there is no existence according to the conflict information carried in the received CORE_INIT_RSP command. Whether there is a conflict between the target RF interface extensions when the enabled RF interface is extended, or whether there is an open RF interface extension between the target RF interface extension and all RF interface extensions of the opened RF interface extension. There is a conflict.

Table 3

It should be noted that the initialization response message CORE_INIT_RSP shown in the foregoing Table 3 is defined by the NCI protocol, where the first three fields are fields defined by the NCI protocol, and the parameters represented by other fields are not reflected in the table in the embodiment of the present invention. in. In the above Table 3, only two subfields in the last field (i.e., the combined number field and the conflict list field in which the conflict exists) are set to implement the embodiment of the present invention. For the above table 3, in the list of radio interface extensions, each time there is a radio interface extension, it takes 1 byte to describe its type (see NCI protocol for details, which is not detailed here); in the conflict list, each conflict The byte (in the case of 1 byte, the specific encoding mode is the same as the conflicting byte described in the above embodiment, as shown in Table 1 or Table 2 above), indicating a set of conflicts, that is, at least two corresponding to the radio interface. There is a conflict between the RF interface extensions. Therefore, when the list of radio interface extensions includes x radio interface extensions, and the conflict list includes y conflicting radio interface extensions, the nth radio interface supported by the NFCC needs to be occupied (x+1+y+1). ) Bytes to describe which RF interface extensions are supported by the RF interface, and which of these RF interface extensions have conflicts.

1014. The DH receives a radio frequency interface activation notification message sent by the NFCC, and obtains the conflict information from the radio frequency interface activation notification message.

In the embodiment of the present invention, the radio frequency interface activation notification message is used to report the result of activating the radio frequency interface to the DH. The radio interface activation notification message may include the type of the activated radio interface and related parameters. For details, refer to the NCI protocol, which is not described here. Then, the conflict information is one or more sets of conflicts that may exist between the radio interface extensions corresponding to the activated radio interface.

During the radio frequency discovery process, the NFCC can activate the notification message through the radio interface (for example, as shown in Table 4, the RF_INTF_ACTIVATED_NTF sent by the NFCC to the DH) to report the conflict information to the DH, and then the DH carries the notification message according to the received radio interface activation notification message. The conflict information is used to determine whether there is a conflict between the radio interface extensions to be opened when there is no open RF interface extension; or when the radio interface expansion is enabled, the radio interface to be opened is expanded and opened. Whether there is a conflict between all RF interface extensions formed by the RF interface extension.

Table 4

It should be noted that the radio interface activation notification message RF_INTF_ACTIVATED_NTF shown in Table 4 above is defined by the NCI protocol. The first two fields are fields defined by the NCI protocol, and the parameters represented by other fields are not reflected in the table in this embodiment. In the above Table 4, only the last two fields (i.e., the combined number field and the conflict list field in which the conflict exists) are set to implement the embodiment of the present invention. In the conflict list, each conflicting byte (in the case of 1 byte, the specific encoding mode is the same as the conflicting byte described in the above embodiment, such as Table 1 or Table 2 above) indicates a set of conflicts, that is, There is a conflict between at least two radio interface extensions corresponding to the radio interface.

1015. The DH receives an open response message or an open notification message sent by the NFCC, and obtains the conflict information from the open response message or the open notification message.

In the embodiment of the present invention, the open response message or the open notification message is an open command sent by the NFCC to the NFCC in response to the DH using an activated radio interface (such as NCI). The RF_INTF_EXT_START_CMD, which is defined by the protocol, is used to report to the DH whether the radio interface extension specified in the open command has been successfully enabled.

It should be noted that, in the embodiment of the present invention, the NFCC may carry the conflict information by using the open response message or the open notification message when receiving the first open command sent by the DH in a radio frequency communication. The conflict information may be one or more sets of conflicts that may exist between the radio interface extensions corresponding to the activated radio interface; or may be the radio frequency specified in the activated radio interface and the first open command. One or more sets of conflicts related to the interface extension. When the activated radio interface is used, one or more other radio interface extensions cannot be enabled at the same time when the radio interface extension specified by the first open command is enabled.

The NFCC may report the conflict information to the DH by opening a response message (such as the RF_INTF_EXT_START_RSP command sent by the DH to the NFCC in Table 5) or by opening a notification message (as shown in Table 6 for the new RF_INTF_EXT_START_NTF command sent by the DH to the NFCC). The DH then determines whether there is a conflict between the target radio interface extensions when there is no open radio interface extension according to the received conflicting information carried in the open response message or the open notification message; or, when there is an enabled radio frequency When the interface is extended, there is a conflict between the target RF interface extension and all RF interface extensions that are formed by the extended RF interface extension.

Table 5

Table 6

It should be noted that the ON response message RF_INTF_EXT_START_RSP shown in Table 5 above is defined by the NCI protocol, where the first three fields are fields defined by the NCI protocol, and the parameters represented by other fields are not reflected in the table in the embodiment of the present invention. in. In the above Table 5, only the last two fields (i.e., the combined number field and the conflict list field in which the conflict exists) are set to implement the embodiment of the present invention. For the above table 5, in the conflict list, each conflicting byte (in the case of 1 byte, the specific encoding mode is the same as the conflicting byte described in the above embodiment, as shown in Table 1 or Table 2 above) A set of conflicts, that is, a conflict between at least two radio interface extensions corresponding to the radio interface.

The open notification message RF_INTF_EXT_START_NTF and its two fields (ie, the combined number field and conflict list field with conflicts) shown in Table 6 above are set to implement the embodiment of the present invention, and the NFCC can perform the RF interface that is enabled by the DH through RF_INTF_EXT_START_CMD. After the extension, the opening notification message is fed back to the DH. For the above table 6, in the conflict list, each conflicting byte (in the case of 1 byte, the specific encoding mode is the same as the conflicting byte described in the above embodiment, as shown in Table 1 or Table 2 above) A set of conflicts, that is, a conflict between at least two radio interface extensions corresponding to the radio interface.

The method for conflict resolution of the radio frequency interface extension is provided by the embodiment of the present invention. The main controller DH expands the target radio frequency interface according to the acquired conflict information and the target radio frequency interface extension determined from the radio interface extension corresponding to the activated radio interface. At least one of the extensions. Among them, rushing The burst information is used to indicate that there is a conflict between at least two radio interface extensions corresponding to the at least one radio interface. Compared with the prior art, at least one radio frequency interface extension is directly enabled by the screening of the radio frequency interface extension. In the embodiment of the present invention, at least one of the target radio frequency interface extensions can be enabled by the DH according to the conflict information, thereby avoiding the radio frequency. A conflict occurs when there is a conflict between interface extensions, or a conflict occurs when the corresponding function is executed after being turned on. The manner in which the DH obtains the conflict information includes multiple types. The DH may generate the conflict information according to the radio interface extension information sent by the NFCC. Alternatively, the DH may directly obtain the conflict information preset by the system. Alternatively, the DH may receive the three different receivers respectively. Timing to receive conflict information sent by the NFCC. Therefore, the DH can obtain the conflict information in a plurality of different manners, and when the multiple radio interface extensions are enabled, the probability of conflict between the at least two radio interface extensions that are in the open state after the radio interface expansion is enabled is reduced. , thereby improving communication efficiency.

In another implementation manner of the embodiment of the present invention, when there is no open radio interface extension and target radio frequency, the radio frequency interface expansion does not exist in the implementation of the radio interface. When the interface extension includes at least two radio frequency interface extensions, the DH in step 103 of FIG. 2 or FIG. 3 starts at least one of the target radio frequency interface extensions according to the conflict information, and may also be specifically implemented as shown in FIG. Steps 1031 to 1033:

1031. The DH determines, according to the open state of the radio interface extension corresponding to the activated radio interface, that the radio interface expansion does not exist and the target radio interface extension includes at least two radio interfaces. When expanding, there is a conflict between the at least two target radio interface extensions.

1032. When there is no conflict, the DH starts the at least two target radio frequency interface extensions.

In an embodiment of the invention, the absence of a conflict indicates that each of these target radio interface extensions does not conflict or is mutually exclusive with any of the other.

1033. When there is a conflict, the DH starts at least one of the at least two target radio interface extensions according to the priority information of the radio interface extension.

In the embodiment of the present invention, the processing manner for opening at least one radio interface extension from all target radio interface extensions is:

1. If at least one of the target radio interface extensions does not conflict or is mutually exclusive with any other target radio interface extension, the at least one radio interface extension is enabled; and then according to the priority information of the radio interface extension One or more of the RF interface extensions are enabled by selecting the remaining RF interface extensions (each of which is in conflict or mutual exclusion with any other one or more).

2. If each of these target RF interface extensions conflicts or is mutually exclusive with one or more other target RF interface extensions, directly select the target RF interface extensions based on the priority information of the RF interface extensions. Thereby opening one or more of the RF interface extensions.

For the above 1 and 2, there are conflicts in the extension of the target radio frequency interfaces. The manner in which the DH selects one or more on according to the priority information of the radio interface includes, but is not limited to, the following ones:

(1) If there is a group conflict, that is, at least two of the target radio interface extensions are conflicting or mutually exclusive, or at least three are two or two conflicts or mutually exclusive, the priority information according to the radio interface extension Find the highest priority RF interface expansion in this group.

(2) If there are multiple groups of conflicts, that is, each group's internal RF interface expansion is two-two conflicts or mutually exclusive, and multiple groups may not conflict with each other or are mutually exclusive, or may be only one group. If the individual RF interface extension conflicts or is mutually exclusive with the individual or all RF interface extensions in other groups, the highest priority RF interface extension is found in each group according to the priority information of the RF interface extension; then, for each of these groups, look for The highest-priority radio interface extension is used, and the processing manner described in the above 1 or 2 and the determining manner described in (1) or (2) are used; finally, one or more radio interface extensions in the target radio interface extension are enabled. .

The method for conflict resolution of the radio frequency interface extension provided by the embodiment of the present invention, the main controller DH expands according to the acquired conflict information and the target radio frequency interface determined from the radio interface extension corresponding to the activated radio interface, when there is no existing When the enabled RF interface is extended and the target RF interface extension includes at least two RF interface extensions, at least one of the target RF interface extensions is turned on according to the conflict information. The conflict information is used to indicate that there is a conflict between at least two radio interface extensions corresponding to the at least one radio interface. Compared with the prior art, the at least one radio frequency interface extension is directly enabled by the screening of the RF interface extension. The embodiment of the present invention may be configured by the DH according to the conflict information, when there is no open RF interface extension and the target radio interface extension includes at least When the two RF interfaces are extended, at least one of the target RF interface extensions is enabled, thereby avoiding an open failure caused by a conflict between the RF interface extensions, or a conflict when the corresponding function is executed after being turned on. Therefore, when multiple radio interface extensions are enabled, the DH reduces the probability of collision between at least two radio interface extensions that are in the on state after the radio interface expansion is enabled, thereby improving communication efficiency.

In another implementation manner of the embodiment of the present invention, when there is an extended radio frequency interface extension, FIG. 2 is used to ensure that the radio interface expansion occurs after the radio interface expansion is enabled for different application scenarios. Or the DH of the step 103 in FIG. 3 is used to enable at least one of the target radio interface extensions according to the conflict information, and may be specifically implemented as step 1034 to step 1036 as shown in FIG. 5:

1034. The DH determines, according to the open state of the radio interface extension corresponding to the activated radio interface, whether there is a conflict between all radio interface extensions when there is an extended radio interface extension.

The radio interface extension includes the target radio interface extension and the opened radio interface extension.

1035. When there is no conflict, the DH enables all target radio interface extensions.

In the embodiment of the present invention, there is no conflict indicating that each of the target radio interface extensions does not conflict or is mutually exclusive with any one of the target radio interface extensions except the one radio interface itself, and is currently Any of the enabled RF interface extensions does not conflict or is not mutually exclusive.

1036. When there is a conflict, the DH starts at least one of all target radio interface extensions according to the priority information of the radio interface extension.

On the basis of the implementation of the steps 1031 to 1034, if there is an extended radio interface extension, at least one of the target radio interface extensions is enabled according to the possible opening of the radio interface extension and the priority of the opened radio interface extension. Or determine which RF interface extensions cannot be turned on, and turn off the open RF interface extensions that need to be turned off. That is, in a manner similar to the processing mode and the determining manner described in the foregoing embodiment, one or more target radio frequency interface extensions are opened from all radio frequency interface extensions including the target radio frequency interface extension and the opened radio frequency interface extension, and You can turn off the turned-on RF interface expansion that needs to be turned off. Of course, you can Using the processing mode and the determining manner described in the foregoing embodiment, one or more RF interface extensions that are possible to be opened are initially determined from the target radio frequency interface extension (in this case, at least two radio frequency interface extensions), and then the foregoing implementation is implemented. The processing mode and the determining manner described in the example, and finally opening one or more of the target radio frequency interface extensions, including all radio frequency interface extensions including the radio interface expansion and the opened radio interface expansion that are initially determined to be possible. The RF interface is extended and it is also possible to turn off one or more of the enabled RF interface extensions. In the embodiment of the present invention, when one or more radio frequency interface extensions in the target radio frequency interface extension are enabled according to the priority of the radio frequency interface extension, and the radio interface expansion in the opened radio frequency interface extension does not exist, the radio interface that conflicts with the target radio frequency interface extension does not exist. When extended, the opened RF interface extension can be maintained on. When one or more radio interface extensions in the target radio interface extension are enabled according to the priority of the radio interface expansion, and at least one radio interface extension that conflicts with the at least one target radio interface extension exists in the opened radio interface extension, The at least one opened radio interface is expanded, and only after the at least one enabled radio interface extension is turned off, the enabled radio interface expansion can be ensured after the target radio interface expansion is enabled. There is no conflict or mutual exclusion between them.

A method for conflict resolution of a radio frequency interface extension is provided by the embodiment of the present invention. The main controller DH expands according to the acquired conflict information and the target radio frequency interface determined from the radio interface extension corresponding to the activated radio interface. The RF interface is extended and the target RF interface extension includes at least one of the target RF interface extensions according to the conflict information when the at least one RF interface is extended. The conflict information is used to indicate that there is a conflict between at least two radio interface extensions corresponding to the at least one radio interface. Compared with the prior art, the at least one radio frequency interface extension is directly enabled by the screening of the radio frequency interface extension. The embodiment of the present invention may be based on the conflict information, and when there is an extended radio frequency interface extension and the target radio frequency interface extension includes at least When one RF interface is extended, at least one of the target RF interface extensions is enabled, thereby avoiding an open failure caused by a conflict between the RF interface extensions, or a conflict when the corresponding function is executed after being turned on. Therefore, when multiple radio interface extensions are enabled, the DH reduces the probability of collision between at least two radio interface extensions that are in the on state after the radio interface expansion is enabled, thereby improving communication efficiency.

In another implementation of the embodiment of the present invention, step 1034 is performed in FIG. 5 The DH determines whether there is a conflict between all the radio interface extensions when there is an open radio interface extension according to the open status of the radio interface extension corresponding to the activated radio interface. At least one of the turned-on RF interface extensions is turned off. Therefore, it can also be implemented as shown in Figure 6:

104. When there is a conflict, the DH turns off at least one of the opened radio interface extensions according to the priority information of the radio interface extension.

It should be noted that, when there is a radio interface expansion that needs to be closed, step 1035 and step 104 may be performed simultaneously, or after step 104 is performed, step 1035 is performed to reduce the on state after the target radio interface expansion is enabled. There is a probability of collision between at least two radio interface extensions.

When it is not necessary to use a certain RF interface extension, DH can determine whether to send the RF_INTF_EXT_STOP_CMD instruction to the NFCC according to the service requirement and/or the NFCC capability, to command the NFCC to close the RF interface extension, or directly extend the corresponding RF interface interface. The radio interface performs a deactivation operation to shut down the radio interface, thereby turning off all radio interface extensions running on the radio interface.

A method for conflict resolution of a radio frequency interface extension is provided by the embodiment of the present invention. The main controller DH expands according to the acquired conflict information and the target radio frequency interface determined from the radio interface extension corresponding to the activated radio interface. The RF interface is extended and the target radio interface extension includes at least one of the target radio interface extensions according to the conflict information when at least one radio interface extension is extended, and at least one of the opened radio interface extensions may also be turned off. The conflict information is used to indicate that there is a conflict between at least two radio interface extensions corresponding to the at least one radio interface. Compared with the prior art, the at least one radio frequency interface extension is directly enabled by the screening of the radio frequency interface extension. The embodiment of the present invention may be based on the conflict information, and when there is an extended radio frequency interface extension and the target radio frequency interface extension includes at least When one radio interface is extended, at least one of the target radio interface extensions is enabled, and at least one of the opened radio interface extensions may be turned off, thereby avoiding an open failure caused by a conflict between the radio interface extensions, or A conflict occurs when the corresponding function is executed after being turned on. Therefore, when multiple radio interface extensions are enabled, the DH reduces the probability of collision between at least two radio interface extensions that are in the on state after the radio interface expansion is enabled, thereby improving communication efficiency.

The embodiment of the invention provides a method for conflict resolution of radio frequency interface extension, which is performed by a near field communication controller NFCC, and the method includes:

201. The near field communication controller NFCC sends the conflict information to the main controller DH.

The conflicting information is used to indicate that there is a conflict between the at least two radio frequency interface extensions corresponding to the at least one radio frequency interface, so that the DH enables the unopened radio frequency interface extension corresponding to the activated radio frequency interface according to the conflict information. The RF interface extension in the middle.

The method for conflict resolution of the radio frequency interface extension is provided by the embodiment of the present invention. The near field communication controller NFCC sends the conflict information to the DH, and the main controller DH expands according to the obtained conflict information and the radio frequency interface corresponding to the activated radio interface. The target radio interface extension determined in the middle, and at least one of the target radio interface extensions is turned on. The conflict information is used to indicate that there is a conflict between at least two radio interface extensions corresponding to the at least one radio interface. Compared with the prior art, the at least one radio interface extension is directly enabled by the screening of the radio interface extension. In this embodiment, the NFCC may send the conflict information to the DH, so that the DH is activated according to the conflict information. The RF interface expansion in the unopened RF interface extension corresponding to the RF interface. Therefore, when multiple radio interface extensions are enabled, the DH reduces the probability of collision between at least two radio interface extensions that are in the on state after the radio interface expansion is enabled, thereby improving communication efficiency.

In the step 201, the NFCC sends the conflict information to the DH in multiple manners. In another implementation manner of the embodiment of the present invention, the NFCC may send the initialization response message to the DH, and send the radio interface activation notification message to the DH to the DH. Send a start response message or a notification message. Therefore, in step 201, the near field communication controller NFCC sends the conflict information to the main controller DH, which can be implemented as any step in step 2011 to step 2013:

2011. After completing the initialization of the NFCC, the NFCC sends an initialization response message to the DH.

The initialization response message carries the conflict information.

2012. After activating a radio interface, the NFCC sends a radio interface activation notification message to the DH.

The radio interface activation notification message carries the conflict information.

2013, after opening a radio interface extension corresponding to the activated radio interface, The NFCC sends an open response message or a start notification message to the DH.

The opening response message or the opening notification message carries the conflict information.

In the embodiment of the present invention, for the understanding of the above-mentioned NFCC initialization, radio frequency interface activation, and radio interface extension opening, please refer to the NCI protocol, and details are not described herein again.

For example, as shown in FIG. 7 is a flowchart of a method for the DH to obtain the conflict information from the initialization response message sent by the NFCC, and to enable at least one of the target radio interface extensions, that is, the step 101 in FIG. 3 is specifically implemented as step 1013. The process flow shown in Figure 3 is as follows:

301, DH resets the NFCC, wherein the reset process can refer to the NCI protocol.

302. The DH sends an initialization command to the NFCC, where the initialization process may refer to the NCI protocol.

303. The DH receives the initialization response information sent by the NFCC, where the initialization response information carries the conflict information related to the radio interface extension that may exist on each radio interface.

The conflict information is the same as the conflict information described in the foregoing embodiment, and the description and explanation are not repeated here.

304. After the radio frequency discovery process activates a radio interface, the DH determines at least one target radio interface extension.

The radio frequency discovery process and the activation operation of the radio frequency interface may refer to the NCI protocol, and details are not described herein again.

305. Determine whether there is an open radio interface extension currently; if yes, go to step 306; if no, go to step 311.

In the embodiment of the present invention, the extended RF interface extension refers to a radio interface extension that the DH has opened through an NCI command (such as the open command RF_INTF_EXT_START_CMD), that is, the NFCC has started or can start to perform its corresponding function. Of course, the description and explanation of the extended RF interface extension in the embodiment of the present invention are equally applicable to the following embodiments. It should be noted that, in the embodiment of the present invention, this step is optional.

306. The DH determines, according to the conflict information, whether there is a conflict between all the radio interface extensions; if yes, step 307 is performed; if not, the target radio interface extension is used as the radio interface extension to be opened, and step 310 is performed.

In the embodiment of the present invention, if there is an open radio interface extension, the number is not limited, and may be one or multiple. At this point, all RF interface extensions include the The open RF interface extension is extended with the at least one target RF interface described above.

It should be noted that, if step 305 is not performed, all the radio frequency interface extensions may include the foregoing at least one target radio frequency interface extension and other radio frequency interface extensions corresponding to the currently activated radio frequency interface. At this time, the purpose of step 306 is to determine whether there are other radio frequency interface extensions that conflict with or are mutually exclusive with the at least one target radio interface extension.

307. Determine whether there is an open radio interface extension in the conflicting radio interface extension; if yes, go to step 308; if no, go to step 312.

In the embodiment of the present invention, the purpose of the step is to determine whether the radio interface extension that conflicts with or conflicts with the at least one target radio interface extension has an extended radio interface extension, or is one of the opened radio interface extensions. Or multiple.

308. Determine whether the priority of the target radio interface extension is higher than the priority of the opened radio interface extension that conflicts with the target radio interface extension; if yes, perform step 309 to step 310; if not, end the execution. process.

It should be noted that, in the embodiment of the present invention, this step is optional. When the determination result in step 307 is YES, step 309 may be directly executed without determining the priority order, or the current step may be directly ended. Implementation process.

309. The DH determines that the target radio interface is extended to the radio interface extension to be opened, and commands the NFCC to be closed and the radio interface to be opened to extend the conflicted open radio interface extension.

In the embodiment of the present invention, since the number of open radio interface extensions is not limited, the closed radio interface expansion that is turned off is not necessarily all open radio interface extensions. That is, if only one of the enabled RF interfaces is extended and conflicts with the target radio interface extension, and the priority is lower than the target radio interface extension, the opened radio interface extension is closed; if there are multiple enabled radios The interface is extended, and there are M radio interface extensions that conflict with the target radio interface extension. Further, N (M≥N) radio interface extensions in the M radio interface extensions have lower priority than the target radio interface extension. Priority, then, the N open RF interface extensions are turned off, while others do not conflict or are mutually exclusive with the target RF interface extension, or have priority over the target RF interface extension even if there is a conflict or mutual exclusion. The RF interface extension is still open.

310. The DH commands the NFCC to enable the radio interface extension to be opened.

311. The DH determines, according to the conflict information, whether there is a conflict between the target radio interface extensions; if yes, step 312 is performed; if not, the target radio interface extension is used as the radio interface extension to be opened, and step 310 is performed.

It should be noted that this step is optional. On the one hand, the step 305 is optional; on the other hand, after the step 305 is determined, and it is determined that there is no open RF interface extension, if the number of the target radio interface expansion is 1, the step is not needed. Judging, if the number is multiple, you can perform this step.

In addition, when the execution result of this step is YES, the execution process can also be directly ended.

In the embodiment of the present invention, step 305 and step 311 are added to reduce the process of determining the target radio interface extension and the processing process when there is no open radio interface extension, so that the execution process of steps 306 to 309 is omitted.

312. The DH selects one radio interface extension with the highest priority and one or more radio interface extensions without conflict between the target radio interface extensions according to the priority of the target radio interface extension.

In the embodiment of the present invention, one or more radio frequency interface extensions to be opened are determined from the target radio interface extension according to the processing mode and the determining manner described in the foregoing embodiments. Specifically, there may be one or more groups of radio frequency interface extensions that have conflicts. After the first grouping, when there is a set of conflicting RF interface extensions, the DH can determine the highest priority radio interface extension in the set of the existing radio interface extensions and the non-existence according to the priority of the radio interface expansion. Conflicting RF interface extensions, extending these RF interfaces as possible RF interface extensions. After the first grouping, when there are multiple sets of conflicting RF interface extensions, the DH can determine the highest priority radio interface extension among the conflicting RF interface extensions according to the priority of the radio interface extension. Determining the RF interface expansion without conflicts in each of the highest priority RF interface extensions as a possible RF interface extension, and when there is a conflict between each of the highest priority RF interface extensions, then each group is prioritized. The conflicting RF interface extensions in the highest-level RF interface extension are divided into one or more groups. The DH then determines which radio interface extensions are possible to be opened from the radio interface extension after the second packet according to the priority of the radio interface extension participating in the second packet and the conflict condition of the radio interface extension. If there is an open RF interface extension, then according to these possible open RF interface expansion and open The priority of the radio interface is extended to determine which radio interface extensions can be enabled, or which radio interface extensions cannot be enabled, and which radio interface extensions need to be shut down.

In the embodiment of the present invention, by way of example, after the multiple radio interface extensions that can be enabled on an activated radio interface are arranged in descending order of priority, the conflict information extended according to each radio interface is used. The status of the radio interface is enabled to determine the radio interface extension that can be enabled. The specific implementation process is as follows:

The first to the Nth radio interface extensions are selected in the order of the priority of the radio interface extension. The N is less than or equal to M, where M is the number of radio interface extensions corresponding to a single interface, and N is greater than or equal to 2. Integer. When the first radio interface extension is selected, it is determined that the first radio interface is extended to the target radio interface extension. When the second radio interface extension is selected, it is determined whether there is a conflict between the second radio interface extension and the first radio interface extension according to the conflict information; if not, the second radio interface is determined to be the target radio. The interface is extended; if it exists, it is determined that the second radio interface is expanded to be an unopenable radio interface extension. When the Nth radio interface extension is selected, it is determined whether there is a conflict between the Nth radio interface extension and the target radio interface extension in the first N-1 radio interface extensions according to the conflict information; if not, the Nth is determined. The radio interface is extended to the target radio interface. If yes, the Nth radio interface is expanded to be unreachable. If no radio interface expansion is enabled, all target radio interface extensions are determined as radios to be enabled. Interface expansion; when there is an extended RF interface extension, it is determined according to the conflict information whether each target RF interface extension in the target RF interface extension is equal to the opened RF interface corresponding to the priority of the target RF interface extension. There is a conflict between the extensions; if yes, the target radio interface extension is determined to be unreachable radio interface extension; if not, the target radio interface extension is determined to be the radio interface extension to be enabled.

It should be noted that the priority of the radio interface extension and the manner of obtaining the priority of the radio interface extension are not specifically limited in the embodiment of the present invention. The priority of the radio interface extension can be different. For example, the DH can distinguish the priority of the radio interface extension according to the order of the radio interface extension in the conflict information. As shown in Table 2, the conflict byte 1 and The radio interface extension b7-b0 in the collision byte 2 can be arranged in descending order of priority, or from low to high. The priority of the radio interface extension can be obtained in various ways. For example, DH can be stored according to the The priority list of the system presets to obtain the priority of the radio interface extension. Or the DH can obtain the priority of the radio interface extension by obtaining a separate priority list sent by the NFCC, or the DH can determine the priority of the radio interface extension by obtaining the permutation order of each radio interface extension in the radio interface extension information sent by the NFCC. Or DH may obtain the priority of the radio interface extension according to the order of the radio interface extension in the conflict list in Tables 3 to 6 above.

For another example, as shown in FIG. 8 , a flowchart of another method for obtaining the conflict information by the DH from the initialization response information sent by the NFCC, and enabling at least one of the target radio interface extensions, that is, step 101 in FIG. 3 is specifically implemented as steps. Another processing flow shown in Figure 3 at 1014 is as follows:

Steps 401 to 403 are the same as steps 301 to 303 shown in FIG. 7, and are not described here.

404. After the radio frequency discovery process is activated, the DH determines n (n≥1) target radio interface extensions.

405. Determine whether n is equal to 1; if yes, execute step 406; if no, perform step 411.

406. Determine whether there is an extended radio interface extension. If yes, go to step 407. If no, the target radio interface extension is used as the radio interface extension to be enabled. Step 410 is performed.

407. The DH determines, according to the conflict information, whether there is a conflict between all the radio interface extensions; if yes, step 408 is performed; if not, the target radio interface extension is used as the radio interface extension to be opened, and step 410 is performed. 408, determining the target radio frequency Whether the priority of the interface extension is higher than the priority of the opened radio interface extension that conflicts with the target radio interface extension; if yes, step 409 to step 410; if not, the current execution process is terminated.

It should be noted that, in this embodiment of the present invention, this step is optional. When the determination result in step 407 is YES, step 409 may be directly executed without determining the priority order, or the current step may be directly ended. Implementation process.

409. The DH determines that the target radio interface is extended to the radio interface extension to be opened, and the NFCC is closed and the radio interface extension to be opened is extended.

It should be noted that the target radio frequency interface extension determined as the radio interface extension to be opened in this step is not necessarily all radio interface extensions in the target radio interface extension determined in step 404.
