Fig. 3 exemplarily shows a schematic structural diagram of a terminal device applicable to the embodiment of the present application, and as shown in fig. 3, the terminal device includes 4 radio frequency channels, which are a radio frequency channel 1, a radio frequency channel 2, a radio frequency channel 3, and a radio frequency channel 4.

Wherein, rf channel 1 and rf channel 2 support both reception and transmission of signals. Radio frequency channels 3 and 4 only support reception of signals. In the embodiment of the present application, a radio frequency channel capable of supporting transmission of a signal is also referred to as a transmission radio frequency channel, for example, the radio frequency channel 1 and the radio frequency channel 2 may be referred to as transmission radio frequency channels. The number of components used for signal transmission is greater than the number of components used for signal reception, and in one possible embodiment, the number of rf channels supporting signal transmission is greater than the number of rf channels supporting signal reception, taking into account the cost of the terminal device.

In the embodiments of the present application, the radio frequency channel refers to a series of hardware structures and/or software capable of implementing signal transceiving. In the embodiment of the present application, 4 rf channels are taken as an example for illustration. In the embodiments of the present application, a hardware structure and/or software for implementing signal transceiving may be referred to as a radio frequency resource. For example, the hardware structure and/or software for receiving signals on a radio frequency channel may be referred to as a radio frequency resource for receiving signals. The hardware structure and/or software for transmitting signals on one radio frequency channel is referred to as a radio frequency resource for transmitting signals. For example, a radio frequency channel only supports receiving signals, or hardware and/or software on the radio frequency channel may be divided into several parts of radio frequency resources, and a part of radio frequency resources of the radio frequency channel may be allocated to the first communication card for use, so as to implement receiving of signals of the first communication card; and allocating another part of radio frequency resources to the second communication card for use so as to realize the reception of the second communication card signals.

For example, in fig. 3, the hardware structure and/or software in the rf channel 1 are divided into three parts, i.e., an rf resource 305 for transmitting signals, an rf resource 306 for receiving signals, and an rf resource 307 for receiving signals. After the network device allocates a radio frequency resource to a communication card, the communication card can transmit and receive signals through the radio frequency resource.

As shown in fig. 3, a plurality of communication card interfaces, such as a first communication card interface 341 and a second communication card interface 342 shown in fig. 3, may be included in the terminal device. The communication card interface may be the SIM card interface 195 in fig. 2 described above. When the communication card is used specifically, the communication card can be inserted into the communication card interface so as to realize the connection between the communication card and the terminal equipment. And when the communication card is pulled out of the communication card interface, the communication card is disconnected with the terminal equipment.

The operator of each communication card specifies the frequency to be used by the communication card. In this embodiment of the present application, the frequencies used by the first communication card and the second communication card may be the same or different, and this embodiment of the present application is not limited. In specific implementation, if the frequencies of the first communication card and the second communication card are the same, the same frequency interference may be caused, and in order to avoid this problem, the user may select and use two communication cards with different frequencies. The first communication card performs data transmission using a frequency a, and the second communication card performs data transmission using a frequency B, where the frequency a and the frequency B are two different frequencies. As shown in fig. 3, the terminal device may receive and transmit signals of the same frequency band through a duplexer 303 or a switch 304. For example, in the radio channel 1, the radio resource 305 for transmitting a signal and the radio resource 306 for receiving a signal are allocated to a first communication card for use, and the radio resource 307 for receiving a signal is allocated to a second communication card for use, taking the radio channel 1 connection switch 304 as an example, if the switch implements the connection between the radio resource 305 for transmitting a signal and the filter 302, the signal can be transmitted through the radio resource 305 for transmitting a signal, and at this time, the signal cannot be received through the radio resource 306 for receiving a signal. If the switch connects the rf resource 306 for receiving signals to the filter 302, the rf path for receiving signals is in a pass state, and signals can be received by the rf resource 306 for receiving signals, but at this time, signals cannot be transmitted by the rf resource 305 for transmitting signals. Thus, it can be seen that, in the terminal device, the reception and transmission of signals in the same frequency band can be realized through the duplexer 303 or the switch 304.

As shown in fig. 3, since different communication cards use different frequencies, two signals belonging to two frequencies can be separated by a filter in the same radio frequency channel. For example, in the radio channel 1, the radio resource 305 for transmitting signals and the radio resource 306 for receiving signals are allocated to a first communication card, and the radio resource 307 for receiving signals is allocated to a second communication card, the first communication card can perform data transmission by using the frequency a, the second communication card can perform data transmission by using the frequency B, and as shown in fig. 3, the signals of the frequency a and the signals of the frequency B can be separated by the filter 302.

As shown in fig. 3, a radio frequency channel may be connected to an antenna, so that the transmission of signals on the radio frequency channel is realized through the antenna, for example, the signals of the radio frequency channel 1 may be transmitted through the antenna 301. The antenna 301 is of the type of the antenna 1 in fig. 2.

Similarly, as shown in fig. 3, the radio frequency channel 2 includes a radio frequency resource 315 for transmitting signals, a radio frequency resource 316 for receiving signals, a radio frequency resource 317 for receiving signals, a duplexer 313, a switch 314, a filter 312, and an antenna 321. The function is similar to that of the radio frequency channel 1, and the description is omitted here. Compared with the radio frequency channel 1, the radio frequency channel 3 only includes radio frequency resources for receiving signals (such as the radio frequency resource 326 for receiving signals and the radio frequency resource 327 for receiving signals), so that only the filter 322 and the antenna 321 may be disposed in the radio frequency channel 3 for the purpose of receiving signals of different frequency bands. Similarly, only the rf resource 336 for receiving signals, the rf resource 337 for receiving signals, the filter 332 and the antenna 331 are disposed in the rf channel 4, and detailed description thereof is omitted.

In the following contents in the embodiment of the present application, a terminal device is exemplified to have two communication cards, which are a first communication card and a second communication card respectively. In the embodiment of the present application, it should be noted that the "communication card" is a generic concept, and specifically refers to the first communication card and the second communication card.

In the embodiment of the present application, for one of a first communication card and a second communication card: and the terminal equipment determines that the communication card is inserted into the card slot, and then determines that the communication card is in a use state. Or, the terminal device determines that the communication card is not inserted into the card slot, and then determines that the communication card is in an unused state. For another example, for one of the first communication card and the second communication card, the terminal device determines that the communication card is inserted into the card slot, and the communication card is not disabled (for example, one communication card may be disabled by software), and determines that the communication card is in the use state. Or the terminal equipment determines that the communication card is inserted into the card slot and the communication card is forbidden, and then determines that the communication card is in an unused state. That is, whether the communication card is in a used state or an unused state may be determined based on whether the communication card is inserted into the card slot, whether the communication card is inserted into the card slot but is disabled (for example, disabled by software), or the like.

In an optional implementation manner, in the embodiment of the present application, that the first communication card mentioned later is in a used state means that the first communication card is inserted into the terminal device, and that the first communication card is in an unused state means that the first communication card is not inserted into the terminal device; the second communication card is in a use state, namely the second communication card is inserted into the terminal equipment, and the second communication card is in an unused state, namely the second communication card is not inserted into the terminal equipment.

In another optional implementation manner, the fact that the first communication card is in the use state means that the first communication card is inserted into the terminal device and is not disabled. The first communication card is in an unused state, which means that the first communication card is inserted into the terminal device but is disabled, or the first communication card is not inserted into the terminal device. The second communication card is in the use state, namely the second communication card is inserted into the terminal equipment and is not disabled. The second communication card is in an unused state, which means that the second communication card is inserted into the terminal device but is disabled, or that the second communication card is not inserted into the terminal device.

Based on the above, it is preferred to describe a prior art in this document, taking as an example that the first communication card is a master card, and the master card has a capability of supporting two sending radio frequency channels, the second communication card is a slave card, the slave card has a capability of supporting two sending radio frequency channels, and the terminal device has two sending radio frequency channels in total.

Preferably, the terminal device reports the real capabilities of the primary card and the secondary card. That is to say, in the prior art, the number of the sending radio frequency channels supported by the communication card reported by the terminal device is a true value. The specific reported content is as follows: the primary card has the capability of supporting two transmit radio frequency channels and the secondary card has the capability of supporting two transmit radio frequency channels. After receiving the information, the network device allocates rf channels for the primary card and the secondary card to send signals according to the capabilities of the primary card and the secondary card reported by the terminal device and the number of rf channels for sending provided by the terminal device. Preferably, the capability of the main card is satisfied, so that the network device allocates two sending radio frequency channels to the main card, and because the terminal device has only two sending radio frequency channels in total, the network device does not allocate a sending radio frequency channel to the secondary card any more, and in the actual communication process, the secondary card needs to use the sending radio frequency channel in a preemption manner when needing to use the sending radio frequency channel.

In the scheme, when one communication card is in a use state, the other communication card is easy to miss the call. An example is detailed below: for example, the main card is in a calling state, the main card occupies two sending radio frequency channels to send data, at this time, the secondary card has an incoming call, but because the two sending radio frequency channels are occupied by the main card, the secondary card has no way to use the sending radio frequency channels to send data, so that a link between the secondary card and a network cannot be established, and the secondary card cannot successfully access the incoming call. It can be seen that the purpose of double-card double-pass cannot be achieved in the scheme. In order to solve the problem, the present application provides a dual-card dual-standby dual-pass scheme, and fig. 4 exemplarily shows a schematic flow diagram of a dual-card dual-standby dual-pass method, as shown in fig. 4, including:

step 501, the terminal device sends capability indication information to the network device.

Generally speaking, a terminal device wants to acquire a service and needs to register with a network, and this registration process is called Attach (taking LTE system as an example), and the terminal device may send a session access request to the network during the last Attach process to request access to the network. The network sends a first signaling to the terminal equipment, wherein the first signaling is used for indicating the terminal equipment to report the capability indication information. The terminal device may transmit the capability indication information after receiving the first signaling. According to protocol specifications, for example, the capability of each communication card to identify the current terminal device may be indicated by the following three fields (which are specified by the protocol 38.306):

the first field is: "Supported maximum number of SRS antenna port SRS resource", which refers to the information about the maximum port number Supported in the Supported SRS-Resources.

The second field is: the field is the maximum number of streams supported by uplink when the uplink Codebook mode is adopted.

A third field: "maxnumberbelmimo-layersnobb-PUSCH", this field refers to the maximum number of streams supported in uplink when the uplink nocodebook mode is adopted.

Taking the first communication card as an example, if the reported capability indication information indicates that "the first communication card supports 1 sending radio frequency channel", then the capability indication information includes: the content of the first field corresponding to the first communication card is 1. The second field and the third field need to be determined according to the actual situation of the terminal device, for example, the first communication card may support 1 uplink transmission channel in the Codebook mode and 1 uplink transmission channel in the uplink Codebook mode. The contents of the three fields corresponding to the second communication card are similar to the contents of the three fields corresponding to the first communication card, and are not described again. For another example, if the reported capability indication information indicates that the first communication card supports 2 sending radio frequency channels, in the capability indication information: the content of the first field corresponding to the first communication card is 2. The second field and the third field need to be determined according to the actual situation of the terminal device, for example, the first communication card may support 2 uplink transmission channels in the Codebook mode and 1 uplink transmission channel in the non Codebook mode.

Step 502, the terminal device receives configuration information sent by the network device.

The terminal equipment comprises Q radio frequency channels, wherein N sending radio frequency channels are arranged in the Q radio frequency channels, Q is an integer larger than 1, and N is an integer larger than 1 and not larger than Q.

In step 501, the capability indication information reported by the terminal device includes the number of the sending radio frequency channels supported by the first communication card and the number of the sending radio frequency channels supported by the second communication card.

In step 501 of this embodiment, the number of the sending radio frequency channels supported by the communication card reported by the terminal device is determined by combining the number of the communication cards currently in use and the total number of the sending radio frequency channels possessed by the terminal device, and is not only the number of the sending radio frequency channels actually supported by the reporting communication card as in the prior art.

For example, in a first possible application scenario, when the first communication card and the second communication card are in use, the first communication card has a capability of supporting K1 sending radio frequency channels, the second communication card has a capability of supporting K2 sending radio frequency channels, and K1 and K2 are both positive integers.

In a first possible application scenario, the terminal device only has N transmitting rf channels, and the capability is limited, and if (K1+ K2) is greater than N, that is, the N transmitting rf channels cannot satisfy the maximum transmitting capability of the primary card and the secondary card at the same time. Then, in the embodiment of the present application, when reporting the capability indication information, the terminal device does not report the number of the transmission radio frequency channels actually supported by each communication card, but indicates, through the capability indication information: the first communication card has the capability of supporting M transmitting radio frequency channels, and the second communication card has the capability of supporting (N-M) transmitting radio frequency channels; m is a positive integer less than N and not greater than K1, (N-M) is a positive integer not greater than K2.

Based on the capability indication information in the first possible application scenario, the network device configures a sending radio frequency channel for each communication card. In this application scenario, the configuration information is used to indicate: and configuring M sending radio frequency channels in the N sending radio frequency channels to a first communication card, and configuring (N-M) sending radio frequency channels except the M sending radio frequency channels in the N sending radio frequency channels to a second communication card.

In an optional implementation manner, configuring one of N transmission radio frequency channels to the first communication card specifically means: and allocating a radio frequency resource for transmitting signals on a radio frequency channel with the capability of transmitting signals to the first communication card for use so as to realize the transmission of the signals of the first communication card. In an optional implementation manner, configuring one of the N transmission radio frequency channels to the second communication card specifically means: and allocating the radio frequency resource for transmitting signals on a radio frequency channel with the capability of transmitting signals to the second communication card for use so as to realize the transmission of the signals of the second communication card.

Step 503, when the uplink data of the first communication card needs to be sent, the terminal device sends the uplink data of the first communication card through the M sending radio frequency channels.

Step 504, when the uplink data of the second communication card needs to be sent, the terminal device sends the uplink data of the second communication card through the (N-M) sending radio frequency channels.

It can be seen that, although the first communication card actually supports K1 sending radio frequency channels and the second communication card actually supports K2 sending radio frequency channels, the capability indication information reported by the terminal device in the embodiment of the present application is no longer simply a true value, but: and reporting the number of the radio frequency transmission channels supported by each communication card by combining the number of the radio frequency transmission channels actually owned by the terminal equipment and the number of the communication cards in the current use state. For example, it is reported in the above content that the first communication card has the capability of supporting M transmission radio frequency channels, and the second communication card has the capability of supporting (N-M) transmission radio frequency channels. M may actually be smaller than K1, and (N-M) may actually be smaller than K2. It can be seen that, in the embodiment of the present application, the capability indication information reported by the terminal device is improved, which is different from a scheme in the prior art for reporting the number of actually supported transmission radio frequency channels of each communication card.

Further, in the capability indication information reported by the terminal device, the first communication card supports M sending radio frequency channels, and the second communication card supports (N-M) sending radio frequency channels, so that the network device configures M sending radio frequency channels of the N sending radio frequency channels to the first communication card, and configures (N-M) sending radio frequency channels of the N sending radio frequency channels except for the M sending radio frequency channels to the second communication card. Because the two communication cards are both distributed with the sending radio frequency channels, even if the first communication card is in a conversation state, M sending radio frequency channels distributed to the first communication card are occupied, at the moment, if a second communication card has an incoming call, the second communication card can establish a link with a network through the (N-M) sending radio frequency channels distributed to the second communication card, so that the incoming call is received, the problem that the other communication card misses the telephone when one communication card is in a use state can be avoided, and thus, the purpose of double-card double-pass can be realized.

In the first possible application scenario, in a possible implementation manner, in the capability indication information reported by the terminal device, if N is an even number, the N transmission radio frequency channels may be equally divided into two parts, each of which occupies one part, where M is N/2 and (N-M) is N/2. For example, if N is 2, in the reported capability indication information, the number of the transmission radio frequency channels supported by the first communication card is 1, and the number of the transmission radio frequency channels supported by the second communication card is 1. And the configuration information issued by the network equipment indicates that one of the 2 sending radio frequency channels is distributed to the first communication card, and the other sending radio frequency channel is distributed to the second communication card. Therefore, the first communication card and the second communication card can achieve the purpose of double-card double-communication.

Fig. 5 exemplarily shows a schematic allocation diagram of radio frequency channels in a first application scenario, and as shown in fig. 5, if the first communication card has a capability of supporting 2 transmitting radio frequency channels, the second communication card has a capability of supporting 2 transmitting radio frequency channels. Here, K1 and K2 are both 2 merely as an example, and the values of specific K1 and K2 may be different depending on the specific capabilities of the communication card. If the first communication card and the second communication card are both in the use state, the terminal device reports the following capacity indication information: the first communication card has the capability of supporting 1 sending radio frequency channel, and the second communication card has the capability of supporting 1 sending radio frequency channel, and since the terminal device in fig. 5 has 2 sending radio frequency channels, the first communication card and the second communication card can be respectively allocated with 1 sending radio frequency channel. As shown in fig. 5, specifically, the radio resource of the radio channel 1 for transmitting signals may be allocated to a first communication card for use, and the radio resource of the radio channel 2 for transmitting signals may be allocated to a second communication card for use. As can be seen from fig. 5, when the terminal device uses dual cards, each communication card in the dual cards may be allocated with a part of radio frequency resources for sending signals, so as to achieve the purpose of dual-card dual-standby dual-pass.

As shown in fig. 5, the radio resource for receiving signals of each of the 4 radio channels is shared by the first communication card and the second communication card. For example, in the radio channel 1, the radio resource 305 for transmitting signals in the radio channel 1 is allocated to the first communication card, and the radio resource 306 for transmitting and receiving signals in the radio channel 1 is allocated to the first communication card, so that the duplexer 303 or the switch 304 can implement the function of transmitting and receiving signals of the first communication card. In the embodiment of the present application, the radio frequency resource for transmitting a signal may implement transmission of the signal, and the radio frequency resource for receiving the signal may implement reception of the signal. The radio frequency resource 307 for receiving signals in the radio frequency channel 1 is allocated for use by the second communication card. For another example, in the radio frequency channel 2, the radio frequency resource 315 for transmitting signals in the radio frequency channel 2 is allocated to the second communication card for use, and the radio frequency resource 316 for transmitting and receiving signals in the radio frequency channel 2 is allocated to the second communication card for use, so that the duplexer 313 or the switch 314 can implement the function of transmitting and receiving signals of the second communication card. The radio frequency resource 317 for receiving signals in the radio frequency channel 2 is allocated for use by the first communication card. For another example, in the radio channel 3, a radio resource 326 for transmitting and receiving signals in the radio channel 3 is allocated to a first communication card, and a radio resource 327 for receiving signals in the radio channel 3 is allocated to a second communication card. For another example, in rf channel 4, rf resource 336 of rf channel 4 for transmitting and receiving signals is allocated to be used by the first communication card, and rf resource 337 of rf channel 4 for receiving signals is allocated to be used by the second communication card.

In the example shown in fig. 5, of course, if the terminal device has more than two 2 sending radio frequency channels, for example, 4 sending radio frequency channels, if the first communication card has the capability of supporting 2 sending radio frequency channels, and the second communication card has the capability of supporting 2 sending radio frequency channels, the reported capability indication information may indicate that the first communication card has the capability of supporting 2 sending radio frequency channels, and the second communication card has the capability of supporting 2 sending radio frequency channels, so that the network device configures 2 sending radio frequency channels for the first communication card and the second communication card, respectively.

The above discusses a related scheme in a first possible application scenario. A second possible application scenario may also exist in the implementation: the first communication card is in a used state and the second communication card is in an unused state.

In a second possible application scenario, i.e. when the first communication card is in use and the second communication card is not in use, then: when the K1 is smaller than the N, the capability indication information is used to indicate: the first communication card has the capability of supporting K1 transmit radio frequency channels. When the K1 is not less than the N, the capability indication information is used to indicate: the first communication card has the capability of supporting N transmit radio frequency channels. In this embodiment, correspondingly, the network device receives the capability indication information sent by the terminal device, and allocates a sending radio frequency channel to the first communication card according to the capability indication information. And the network equipment configures N sending radio frequency channels for the first communication card according to the capability indication information. Fig. 6 exemplarily shows an allocation diagram of radio frequency channels in the case of a dual card on the basis of fig. 3 when the first communication card is in a use state, and as shown in fig. 6, if the first communication card has a capability of supporting 2 transmitting radio frequency channels, the second communication card has a capability of supporting 2 transmitting radio frequency channels. If the current first communication card is in the use state, the terminal device reports the following capacity indication information: this first communications card has the capability of supporting 2 transmit radio frequency channels, i.e. since N is 2 in fig. 6, M is taken to be 2. As shown in fig. 6, 2 transmission radio frequency channels may be allocated to the first communication card for use, specifically, a radio frequency resource used by the radio frequency channel 1 for transmitting signals may be allocated to the first communication card for use, and a radio frequency resource used by the radio frequency channel 2 for transmitting signals may also be allocated to the first communication card for use. And radio resources in the radio channels 3 and 4, a part of which is used for receiving signals, are allocated to the first communication card for use. As can be seen from the example in fig. 6, if the terminal device uses only one communication card, the radio frequency resource for transmitting signals may be allocated to the communication card according to the maximum capability of the communication card, so that the maximum uplink capability allowed by the hardware resource may be maintained, and the performance of the communication card may be optimized.

A third possible application scenario may exist in the specific implementation: the first communication card is in an unused state and the second communication card is in a used state.

In a third possible application scenario, where the first communication card is in an unused state and the second communication card is in a used state, then: when the K2 is smaller than the N, the capability indication information is used to indicate: the second communication card has the capability of supporting K2 sending radio frequency channels; when the K2 is not less than the N, the capability indication information is used to indicate: the second communication card has the capability of supporting N transmit radio frequency channels. In this embodiment, correspondingly, the network device receives the capability indication information sent by the terminal device, and allocates a sending radio frequency channel to the second communication card according to the capability indication information. And the network equipment configures N sending radio frequency channels for the second communication card according to the capability indication information. Fig. 7 exemplarily shows an allocation diagram of radio frequency channels in the case of dual cards on the basis of fig. 3 when the second communication card is in a use state, as shown in fig. 7, if the second communication card has a capability of supporting 2 transmitting radio frequency channels, the second communication card has a capability of supporting 2 transmitting radio frequency channels. If the second communication card is in the use state at present, the capacity indication information reported by the terminal equipment comprises: the second communication card has the capability of supporting 2 transmission radio frequency channels, and the 2 transmission radio frequency channels can be allocated to the second communication card for use, specifically, as shown in fig. 7, a radio frequency resource of the radio frequency channel 1 for transmitting signals is allocated to the second communication card for use, and a radio frequency resource of the radio frequency channel 2 for transmitting signals is allocated to the second communication card for use. And a part of the radio frequency resources used for receiving signals in the radio frequency channel 3 and the radio frequency channel 4 are allocated to the second communication card for use. Of course, in the example of fig. 7, if K2 is 1, in the capability indication information reported by the terminal device: the second communication card has the capability of supporting 1 transmission radio frequency channel, and 1 transmission radio frequency channel can be allocated to the second communication card for use, and specifically, a radio frequency resource 315 used for transmitting signals on the radio frequency channel 2 can be allocated to the second communication card for use. As can be seen from the example in fig. 7, if the terminal device uses only one communication card, the radio frequency resource for transmitting signals may be allocated to the communication card according to the maximum capability of the communication card, so that the maximum uplink capability allowed by the hardware resource may be maintained, and the performance of the communication card may be optimized.

In step 501, the number of the transmission radio frequency channels supported by the communication card indicated in the capability indication information in the embodiment of the present application may be the same as or different from the number of the transmission radio frequency channels actually supported by the communication card. In the embodiment of the present application, a scheme in the prior art is further provided, which is used for comparing with the schemes provided in the above step 501 and step 502, in the scheme in the prior art, the number of the transmission radio frequency channels supported by the communication card indicated in the capability indication information is the same as the number of the transmission radio frequency channels actually supported by the communication card. In table 1, an example of comparing the embodiment and the comparison scheme of the present application is shown, where in table 1, a terminal device includes 2 transmitting radio frequency channels, that is, N is 2. In table 1, 1T indicates 1 rf channel, and 2T indicates 2 rf channels. The number of the transmitting rf channels actually supported by the communication card in table 1 refers to the number of the maximum number of transmitting rf channels that can be supported by the hardware resource of the communication card. The primary card and the secondary card are preset by the terminal device, for example, the communication card inserted into the first preset card slot is the primary card, and the communication card inserted into the second preset card slot is the secondary card. Or whether the identity of the communication card is a primary card or a secondary card is specified by software. The scheme of the embodiment of the present application is described in table 1 by taking as an example that both the primary card and the secondary card are in use.

Table 1 comparative examples of the present application and comparative schemes

The description is given by taking "the first case above 2.6 GHz" in table 1 as an example, and other application scenarios are similar to them and are not repeated. The first communication card is taken as a main card, and the second communication card is taken as an auxiliary card for explanation. The first communication card supports 2T, the second communication card supports 1T, and in this case, the first communication card and the second communication card are both in a use state, and by adopting the scheme provided by the embodiment of the application, the reported capability indication information indicates that the first communication card supports the number of 1 sending radio frequency channel, and the second communication card supports the number of 1 sending radio frequency channel, and the network device allocates one sending radio frequency channel to the first communication card and allocates the other sending radio frequency channel to the second communication card, so that the purpose of dual-card dual-pass can be achieved. Further, in the comparison scheme, the capability indication information reported by the terminal device indicates that the main card supports the number of 2 transmitting radio frequency channels, the auxiliary card supports the number of 1 transmitting radio frequency channel, and the network device allocates all two transmitting radio frequency channels to the main card for use.

In the step 501, in another optional implementation manner, if the first communication card is a master card and the K1 is smaller than the N, the M is the K1; if the second communication card is a master card and the K2 is less than the N, then the (N-M) is the K2. In this example, if the number of the transmitting radio frequency channels of the terminal device is large, the maximum uplink transmitting capability of the main card can be maintained if the maximum uplink transmitting capability of the main card is supported and the remaining transmitting radio frequency channels are available, and the remaining transmitting radio frequency channels are allocated to the secondary card for use, so that the maximum uplink capability allowed by the hardware resource of the main card is maintained, and the purpose of dual-card and dual-pass is also ensured.

In the embodiment of the application, the terminal device has a dual-card mode and a single-card mode, wherein the dual-card mode means that the first communication card is engaged with the second communication card and both the first communication card and the second communication card are in a use state, and the single-card mode means that only one of the first communication card and the second communication card is in a use state. When the terminal device switches between the dual card mode and the single card mode, the capability indication information in step 502 is reported. Specifically, the capability indication information of the terminal device may be initiated when the terminal device re-accesses the network, and certainly, for example, the terminal device re-accesses the network when being powered on, in which case the capability indication information is reported. For another example, when the usage mode of the communication card of the terminal device is changed, the terminal device will re-access the network, and in this case, the capability indication information will be reported again.

For example, when the terminal device is currently in a use state of both the first communication card and the second communication card, the terminal device will switch from the dual-card mode to the single-card mode, for example, the terminal device will adopt a mode of using only the first communication card, and then the user will take the following actions: the second communication card may be removed from the card slot by the user or disabled by software. In this case, the terminal devices all need to re-access the network, and certainly need to report the capability indication information again. For another example, the terminal device switches from the single-card mode to the dual-card mode, for example, only the first communication card is currently used, and after the switching, both the first communication card and the second communication card of the terminal device are in the use state, in this case, the user needs to take the following operations: and inserting the second communication card into the card slot, or releasing the disablement of the second communication card in a software manner, in this case, the terminal devices also need to re-access the network, and certainly need to report the capability indication information again.

In the embodiments of the present application, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple.

And, unless specifically stated otherwise, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing between a plurality of objects, and do not limit the order, sequence, priority, or importance of the plurality of objects. For example, the first communication card and the second communication card are used only for distinguishing different communication cards, and do not indicate a difference in priority, importance, or the like between the two communication cards.
