Description

Technical Field

[0001] The present disclosure relates to the field of mobile communications, and in particular to a communication control method, apparatus, communication equipment, storage medium and chip. Background Art

[0002] In the field of wireless communications, communication cards have two working states: connected (CONNECTED) and idle (IDLE). In the connected state, the communication card can interact with network devices or other entities for data and signaling through the corresponding terminal. At this time, the communication card cannot enter the sleep mode and the power consumption is high. In the idle state, the communication card cannot immediately interact with network devices or other entities for data and signaling through the corresponding terminal. It is necessary to jump to the connected state through the service request process to transmit data. When the communication card is in the idle state, it only needs to periodically monitor paging and can enter the sleep mode with low power consumption.

[0003] In the current communication control scheme, the connection of the communication card can be released directly through the terminal locally, but due to the lack of synchronization with the communication connection device, the paging loss rate is high; or by introducing multiple update requests, the network burden is heavy and there is no clear standard support. When the device that is connected to the terminal corresponding to the communication card does not release the connection immediately, the communication card cannot enter the idle state.

[0036] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0037] In the field of wireless communications, communication cards have two working states: connected (CONNECTED) and idle (IDLE). In the connected state, the communication card can interact with network devices or other entities for data and signaling through the corresponding terminal. At this time, the communication card cannot enter the sleep mode and the power consumption is high. In the idle state, the communication card cannot immediately interact with network devices or other entities for data and signaling through the corresponding terminal. It is necessary to jump to the connected state through the service request process to transmit data. When the communication card is in the idle state, it only needs to periodically monitor paging and can enter the sleep mode with low power consumption.

[0038] In the current communication control scheme, the connection of the communication card can be released directly through the terminal locally, but due to the lack of synchronization with the communication connection device, the paging loss rate is high; or by introducing multiple update requests, the network burden is heavy and there is no clear standard support. When the device that is connected to the terminal corresponding to the communication card does not release the connection immediately, the communication card cannot enter the idle state.

[0039] Therefore, in order to solve the problems existing in the related technology, the present disclosure proposes a communication control method, in which a first terminal sends a first information to a first device, and the first information is used to indicate that the first terminal supports the connection release function of the first communication card, so that the first terminal can effectively put the communication card into an idle state under the premise of synchronization with the first device connected to the communication, thereby improving the flexibility of communication control. At the same time, it is determined that the first communication card meets the first condition. Under the first condition, the connection of the first communication card is released, so that the first terminal can quickly identify whether the communication card can release the connection, further reducing the power consumption of the terminal, and at the same time realizing the rapid connection release of the communication card in the single communication card terminal.

[0040] Figure 1 A flow chart of a communication control method provided by an embodiment of the present disclosure, such as Figure 1 As shown, the communication control method includes step 101.

[0041] Step 101: Send first information to a first device.

[0042] In some embodiments, the first terminal sends first information to the first device, and the first information is used to indicate that the terminal supports the connection release function of the first communication card, so that the first device determines that the first terminal supports the connection release function of the first communication card, laying the foundation for the first device and the first terminal to synchronously release the connection of the first communication card.

[0043] In some embodiments, the first terminal is a terminal supporting a first communication card.

[0044] In some embodiments, the first device is communicatively coupled to the terminal.

[0045] In some embodiments, the first information is used to indicate that the terminal supports a connection release function of the first communication card.

[0046] In some embodiments, the connection release of the first communication card is not limited, and it may be, for example, a NAS signaling connection release, a Radio Resource Control connection release, or the like.

[0047] In some embodiments, the first terminal supports only a single communication card, and the first communication card is the single communication card supported by the first terminal.

[0048] Optionally, in some embodiments, the first terminal may support two or more communication cards, and the first communication card may be any one of the multiple communication cards.

[0049] In some embodiments, the type of the first device is not limited, and it may be a network device that is communicatively connected to the first terminal, or it may be another terminal that is communicatively connected to the first terminal via a sidelink.

[0050] In some embodiments, the first information may be sent to the first device when the first terminal establishes a communication connection with the first device for the first time; the first information may also be sent to the first device when the first terminal initiates a service (for example, a voice call, a video conference, etc.), but is not limited to this. The present disclosure does not limit the execution time of step 101.

[0051] In summary, according to the communication control method proposed in the present disclosure, the method includes: sending first information to the first device, the first information is used to indicate that the first terminal supports the connection release function of the first communication card, and the first device is connected to the first terminal in communication. The scheme of the present disclosure sends the first information to the first device through the first terminal, so that the first device determines that the first terminal supports the connection release function of the first communication card, thereby proposing a communication control method, which can make the first communication card enter the idle state in time, improve the flexibility of the connection release of the first communication card, reduce the power consumption of the first terminal, and realize the rapid connection release of the communication card in the single communication card terminal.

[0052] Figure 2 A flow chart of a communication control method proposed in the present disclosure is further shown. Figure 1 The embodiment shown, further describing, the method comprises the following steps:

[0053] Step 201: Send first information to a first device.

[0054] In some embodiments, the first terminal sends first information to the first device, and the first information is used to indicate that the first terminal supports the connection release function of the first communication card, so that the first device determines that the first terminal supports the connection release function of the first communication card, laying a foundation for the first terminal and the first device to flexibly release the connection of the first communication card under synchronization conditions.

[0055] In some embodiments, the first terminal is a terminal supporting a first communication card.

[0056] In some embodiments, the first device is communicatively coupled to the terminal.

[0057] In some embodiments, the first information is used to indicate that the terminal supports a connection release function of the first communication card.

[0058] In some embodiments, the first terminal only supports a single communication card, and the first communication card is the single communication card supported by the first terminal.

[0059] Optionally, in some embodiments, the first terminal may support two or more communication cards, and the first communication card may be any one of the multiple communication cards.

[0060] In some embodiments, the type of the first device is not limited, and it may be a network device that is communicatively connected to the first terminal, or it may be another terminal that is communicatively connected to the first terminal via a side link.

[0061] In some embodiments, the first information may be sent to the first device when the first terminal establishes a communication connection with the first device for the first time; the first information may also be sent to the first device when the first terminal initiates a service (for example, a voice call, a video conference, etc.), but is not limited to this. The present disclosure does not limit the execution time of step 201.

[0062] For example, the first device is a network device. When the first terminal establishes a communication connection with the network device for the first time, the first terminal sends first information to the network device, where the first information indicates that the first terminal supports the NAS signaling connection release function of a single communication card.

[0063] Step 202: Receive second information sent by the first device.

[0064] In some embodiments, the first terminal receives second information sent by the first device, and the second information is used to indicate that the first device supports the connection release function of the first communication card, so that the first terminal determines that the first device supports the connection release function of the first communication card, laying a foundation for the first device and the first terminal to flexibly release the connection of the first communication card under synchronization conditions.

[0065] In some embodiments, the type of the first device is not limited, and it may be a network device that is communicatively connected to the first terminal, or it may be another terminal that is communicatively connected to the first terminal via a side link.

[0066] In some embodiments, the second information is used to indicate that the first device supports a connection release function of the first communication card.

[0067] In some embodiments, the second information sent by the first device can be received when the first terminal establishes a communication connection with the first device for the first time; the second information sent by the first device can also be received when the first terminal initiates a service (for example, a voice call, a video conference, etc.), but is not limited to this. The present disclosure does not limit the execution time of step 202.

[0068] For example, the first device is a network device. When the first terminal establishes a communication connection with the network device for the first time, the first terminal can receive second information sent by the network device, and the second information indicates that the network device supports the connection release function of a single communication card, that is, the network device supports the NAS signaling connection release function of a single communication card.

[0069] Step 203: Receive third information sent by the first device.

[0070] In some embodiments, the first terminal receives third information sent by the first device to determine that the first device successfully receives information related to the current service sent by the first terminal, laying the foundation for the first terminal to determine that the connection of the first communication card can be released.

[0071] In some embodiments, the third information is used to indicate that the first device successfully receives information related to the current service sent by the first terminal.

[0072] In some embodiments, the current service is an ongoing communication service between the first terminal and the first device, such as a voice call, a video conference, etc. The present disclosure does not limit the service type of the current service.

[0073] In some embodiments, the relevant information of the current service may be information sent by the first terminal to the first device when performing the service, such as data information, communication quality information of the service, etc., which is not limited in the present disclosure.

[0074] For example, the first device is a network device. The first terminal receives third information sent by the network device, wherein the third information includes an acknowledgement character (ACK) to indicate that the network device successfully receives the current service-related information sent by the first terminal.

[0075] In some embodiments, step 203 is optional, and the first terminal may confirm in other ways that the first device successfully receives the information related to the current business sent by the first terminal; or this step is omitted, and the first terminal assumes that the first device successfully receives the information related to the current business sent by the first terminal. The present disclosure does not limit this.

[0076] Step 204: Determine whether the first communication card satisfies the first condition.

[0077] In some embodiments, the first terminal determines that the first communication card meets the first condition, so that the first terminal can release the connection to the first communication card in time, thereby reducing power consumption of the first terminal.

[0078] In some embodiments, the first condition is used to determine that the first terminal can release the connection of the first communication card.

[0079] In some embodiments, the first condition includes at least one of the following: the first communication card completes the current service; the first communication card does not need to maintain connection with the first device; the first device successfully receives information related to the current service. It should be understood that when all or part of the above contents are met, the first terminal can determine that the first communication card meets the first condition.

[0080] For example, in some embodiments, the first terminal assumes that the first device can successfully receive information related to the previous service. It is only necessary to determine that the first communication card completes the current service, and the first communication card does not need to maintain a connection with the first device to determine that the first communication card meets the first condition.

[0081] For example, in some embodiments, the first terminal determines that the first device successfully receives information related to the current service, that is, it can be determined that the first communication card meets the first condition.

[0082] For example, the first device is a network device. The application processor (AP) of the first terminal can determine that the first access card does not need to maintain a connection with the first device, for example, the AP determines that the first access card does not need to maintain a NAS signaling connection with the network device. Optionally, the AP can also send the determination result to a modem (Modulator-demodulator, Modem) of the first terminal.

[0083] For example, the first device is a network device. The modem of the first terminal can determine that the first communication card has completed the current service, for example, the modem determines that the call, text message and other services performed by the first communication card have been completed.

[0084] For example, the first device is a network device. The first terminal can determine that the network device successfully receives all protocol data units (PDUs) on the resource blocks (RBs) in the radio link control layer (Radio Link Control, RLC) of the first terminal by receiving the third information sent by the network device.

[0085] In some embodiments, the first terminal may determine whether the first communication card satisfies the first condition within a preset time. For example, the first terminal may periodically check whether the first communication card satisfies the first condition according to a preset period when the first communication card is in a connected state; the first terminal may also check whether the first communication card satisfies the first condition at a preset time point (such as when the first communication card has been in a connected state for five minutes, seven minutes, etc.) when the first communication card is in a connected state. The present disclosure does not limit the preset time.

[0086] Step 205: Under the first condition, release the connection of the first communication card.

[0087] In some embodiments, the first terminal can release the first communication card under a first condition, so that the first terminal can promptly put the first communication card into an idle state, thereby improving the flexibility of the connection release of the first communication card, reducing the power consumption of the first terminal, and realizing the rapid connection release of the communication card in a single communication card terminal.

[0088] In summary, according to the scheme of this embodiment, by sending the first information to the first device, the first information is used to indicate that the first terminal supports the connection release function of the first communication card, and the first device is connected to the first terminal in communication; receiving the second information sent by the first device, the second information is used to indicate that the first device supports the connection release function of the first communication card; receiving the third information sent by the first device, the third information is used to indicate that the first device successfully receives the information related to the current service sent by the first terminal; determining that the first communication card meets the first condition, the first condition is used to determine that the first terminal can release the connection of the first communication card, wherein the first condition includes at least one of the following: the first communication card completes the current service, the first communication card does not need to maintain connection with the first device, and the first device successfully receives the information related to the current service; under the first condition, the connection of the first communication card is released. Thus, the first terminal can timely put the first communication card into the idle state, improve the flexibility of the connection release of the first communication card, reduce the power consumption of the first terminal, and realize the fast connection release of the communication card in the single communication card terminal.

[0089] Figure 3 A flow chart of a communication control method proposed in the present disclosure is further shown. Figure 1 , Figure 2 The illustrated embodiment specifically describes the above step 205. In this embodiment, step 205 may include the following steps.

[0090] Step 301: Send fourth information to the first device.

[0091] In some embodiments, the first terminal sends fourth information to the first device to notify the first device that the first terminal is ready to release the connection of the first communication card, so that the first device initiates the connection release of the first communication card and realizes synchronous release of the connection of the first communication card with the first device.

[0092] In some embodiments, the fourth information is used to notify the first device that the first terminal is ready to release the connection of the first communication card.

[0093] In some embodiments, the fourth information may carry NAS signaling, protocol data unit (PDU) signaling, etc., which is not limited in the present disclosure.

[0094] In some embodiments, the type of the first device is not limited, and it may be a network device that is communicatively connected to the first terminal, or it may be another terminal that is communicatively connected to the first terminal via a side link.

[0095] By way of example, the first device is a network device. The first terminal sends a NAS signaling to the network device to notify the network device that the first terminal releases the connection of the first communication card.

[0096] Step 302: Receive fifth information sent by the first device.

[0097] In some embodiments, the first terminal receives the fifth information sent by the first device to determine that the first device initiates the release of the connection with the first communication card, so that the first terminal can release the connection with the first communication card based on the fifth information, thereby achieving synchronous release of the connection with the first communication card with the first device.

[0098] In some embodiments, the fifth information is used to instruct the first device to initiate a connection release with the first communication card.

[0099] In some embodiments, the fifth information may carry NAS signaling, PDU signaling, etc., which is not limited in the present disclosure.

[0100] By way of example, the first device is taken as a network device for illustration. The first terminal receives NAS signaling sent by the network device to determine that the first device initiates the release of the connection with the first communication card.

[0101] Step 303: Based on the fifth information, release the connection of the first communication card.

[0102] In some embodiments, the first terminal determines that the first device initiates a connection release with the first communication card based on the fifth information, and releases the connection with the first communication card, thereby releasing the connection with the first device synchronously with the first communication card and avoiding paging loss.

[0103] It should be understood that the first terminal and the first device synchronously release the connection of the first communication card, which may be releasing the connection of the first communication card at the same time point or within the same time period, and the present disclosure does not limit this.

[0104] In summary, according to the scheme of the embodiment of the present disclosure, by sending the fourth information to the first device, the fourth information is used to notify the first device that the first terminal is ready to release the connection of the first communication card; receiving the fifth information sent by the first device, the fifth information is used to instruct the first device to initiate the connection release with the first communication card; based on the fifth information, the connection release of the first communication card is performed. Thus, a communication control method is realized, so that the first terminal notifies the first device to release the connection of the first communication card, thereby realizing that the first terminal and the first device synchronously release the connection of the first communication card, and avoiding paging loss.

[0105] Figure 4 A flow chart of a communication control method provided by an embodiment of the present disclosure, such as Figure 4 As shown, the communication control method includes step 401.

[0106] Step 401: Receive first information sent by a first terminal.

[0107] In some embodiments, the first device receives first information sent by the first terminal, and the first information is used to indicate that the first terminal supports the connection release function of the first communication card, so that the first device determines that the first terminal supports the connection release function of the first communication card, laying the foundation for the first device and the first terminal to synchronously release the connection of the first communication card.

[0108] In some embodiments, the first device is communicatively coupled to the terminal.

[0109] In some embodiments, the first information is used to indicate that the terminal supports a connection release function of the first communication card.

[0110] In some embodiments, the connection release of the first communication card is not limited, and it may be, for example, a NAS signaling connection release, a Radio Resource Control connection release, or the like.

[0111] In some embodiments, the type of the first device is not limited, and it may be a network device that is communicatively connected to the first terminal, or it may be another terminal that is communicatively connected to the first terminal via a sidelink.

[0112] In some embodiments, the first terminal is a terminal supporting a first communication card.

[0113] In some embodiments, the first terminal only supports a single communication card, and the first communication card is the single communication card supported by the first terminal.

[0114] Optionally, in some embodiments, the first terminal may support two or more communication cards, and the first communication card may be any one of the multiple communication cards.

The present disclosure does not limit the execution time of step 401.

[0116] In summary, according to the communication control method proposed in the present disclosure, the method includes: receiving first information sent by a first terminal, the first information is used to indicate that the first terminal supports the connection release function of the first communication card, and the first terminal is connected to the first device for communication. The scheme of the present disclosure receives the first information sent by the first terminal by the first device, so that the first device determines that the first terminal supports the connection release function of the first communication card, thereby proposing a communication control method, which can timely make the first communication card enter the idle state, improve the flexibility of the connection release of the first communication card, reduce the power consumption of the first terminal, and realize the rapid connection release of the communication card in the single communication card terminal.

[0120] In some embodiments, the first device is communicatively coupled to the terminal.

[0121] In some embodiments, the first information is used to indicate that the terminal supports a connection release function of the first communication card.

[0122] In some embodiments, the type of the first device is not limited, and it may be a network device that is communicatively connected to the first terminal, or it may be another terminal that is communicatively connected to the first terminal via a sidelink.

[0130] In some embodiments, the second information is used to indicate that the first device supports a connection release function of the first communication card.

[0131] In some embodiments, the first device may send the second information to the first terminal when a communication connection is first established with the first terminal; or may send the second information to the first terminal when the first terminal initiates a service (for example, a voice call, a video conference, etc.), but is not limited to this. The present disclosure does not limit the execution time of step 502.

[0132] For example, the first device is a network device. When the network device establishes a communication connection with the first terminal for the first time, it sends second information to the first terminal, and the second information indicates that the network device supports the connection release function of a single communication card, that is, the network device supports the NAS signaling connection release function of a single communication card.

[0133] Step 503: Send third information to the first terminal.

[0134] In some embodiments, the first device sends third information to the first terminal to determine that the first device successfully receives information related to the current service sent by the first terminal, laying a foundation for the first terminal to determine that the connection of the first communication card can be released.

[0135] In some embodiments, the third information is used to indicate that the first device successfully receives information related to the current service sent by the first terminal.

[0136] In some embodiments, the current service is an ongoing communication service between the first device and the first terminal, such as a voice call, a video conference, etc. The present disclosure does not limit the service type of the current service.

[0137] In some embodiments, the information related to the current service may be data information sent by the first device when performing the service, communication quality information of the service, etc., which is not limited in the present disclosure.

[0138] For example, the first device is a network device. The network device sends third information to the first terminal, wherein the third information includes an acknowledgement character (ACK) to indicate that the network device successfully receives the information related to the current service sent by the first terminal.

[0139] In some embodiments, step 503 is optional, and the first terminal may confirm in other ways that the first device successfully receives the information related to the current business sent by the first terminal; or this step is omitted, and the first terminal assumes that the first device successfully receives the information related to the current business sent by the first terminal. The present disclosure does not limit this.

[0140] Step 504: Receive fourth information sent by the first terminal.

[0141] In some embodiments, the first device receives fourth information sent by the first terminal to determine that the first terminal is ready to release the connection of the first communication card, thereby initiating the connection release of the first communication card, so that the first device can release the connection of the first communication card synchronously with the first terminal.

[0142] In some embodiments, the fourth information is used to notify the first device that the first terminal is ready to release the connection of the first communication card.

[0143] In some embodiments, the fourth information may carry NAS signaling, protocol data unit (PDU) signaling, etc., which is not limited in the present disclosure.

[0144] By way of example, the first device is a network device. The network device receives a NAS signaling sent by the first terminal to determine that the first terminal is ready to release the connection of the first communication card.

[0145] Step 505: Send fifth information to the first terminal.

[0146] In some embodiments, the first device sends fifth information to the first terminal so that the first terminal determines that the first device initiates the release of the connection with the first communication card, thereby achieving the first device and the first terminal synchronously releasing the connection with the first communication card.

[0147] In some embodiments, the fifth information is used to instruct the first device to initiate a connection release with the first communication card.

[0148] In some embodiments, the fifth information may carry NAS signaling, PDU signaling, etc., which is not limited in the present disclosure.

[0149] By way of example, the first device is a network device. The network device sends a NAS signaling to the first terminal, so that the first terminal determines that the first device initiates the release of the connection with the first communication card.

[0150] In summary, according to the communication control method proposed in the present disclosure, the method includes: receiving first information sent by the first terminal, the first information is used to indicate that the first terminal supports the connection release function of the first communication card, and the first terminal is connected to the first device for communication; sending second information to the first terminal, the second information is used to indicate that the first device supports the connection release function of the first communication card; sending third information to the first terminal, the third information is used to indicate that the first device successfully receives information related to the current service; receiving fourth information sent by the first terminal, the fourth information is used to notify the first device that the first terminal is ready to release the connection of the first communication card; sending fifth information to the first terminal, the fifth information is used to indicate that the first device initiates the connection release with the first communication card. Thus, a communication control method is realized, so that the first terminal notifies the first device to release the connection of the first communication card, thereby realizing that the first terminal and the first device synchronously release the connection of the first communication card, avoiding paging loss; at the same time, the first communication card can be put into an idle state in time, thereby improving the flexibility of the connection release of the first communication card, reducing the power consumption of the first terminal, and realizing the fast connection release of the communication card in the single communication card terminal.

[0151] Figure 6 The following is a flow chart of an interactive method for communication control provided by an embodiment of the present disclosure. Figure 6 As shown, the interactive method may include the following steps.

[0152] Step 601: A first terminal sends first information to a first device.

[0153] In some embodiments, the first terminal sends first information to the first device, and the first information is used to indicate that the terminal supports the connection release function of the first communication card, so that the first device determines that the first terminal supports the connection release function of the first communication card, laying the foundation for the first device and the first terminal to synchronously release the connection of the first communication card.

[0154] In some embodiments, the first terminal is a terminal supporting a first communication card.

[0155] In some embodiments, the first device is communicatively coupled to the terminal.

[0156] In some embodiments, the first information is used to indicate that the terminal supports a connection release function of the first communication card.

[0157] In some embodiments, the first terminal only supports a single communication card, and the first communication card is the single communication card supported by the first terminal.

[0159] In some embodiments, the type of the first device is not limited, and it may be a network device that is communicatively connected to the first terminal, or it may be another terminal that is communicatively connected to the first terminal via a sidelink.

The present disclosure does not limit the execution time of step 601.

[0161] In summary, the interactive method of communication control proposed in the present disclosure includes: a first terminal sends a first message to a first device, the first message is used to indicate that the first terminal supports the connection release function of the first communication card, and the first device is connected to the first terminal in communication. The scheme of the present disclosure sends the first message to the first device through the first terminal, so that the first device determines that the first terminal supports the connection release function of the first communication card, thereby proposing a communication control method, which can make the first communication card enter the idle state in time, improve the flexibility of the connection release of the first communication card, reduce the power consumption of the first terminal, and realize the rapid connection release of the communication card in the single communication card terminal.

[0162] Optionally, in some embodiments, the first terminal may also send first information to the first device, where the first information is used to indicate that the first terminal supports the connection release function of the first communication card, and the first device is communicatively connected with the first terminal.

[0163] Optionally, in some embodiments, the first terminal may also receive second information sent by the first device, where the second information is used to indicate that the first device supports a connection release function of the first communication card.

[0164] Optionally, in some embodiments, the first terminal may also determine that the first communication card satisfies a first condition, where the first condition is used to determine that the first terminal can release the connection of the first communication card; under the first condition, the connection of the first communication card is released.

[0165] Optionally, in some embodiments, the first condition includes at least one of the following: the first communication card completes the current service; the first communication card does not need to maintain connection with the first device; the first device successfully receives information related to the current service.

[0166] Optionally, in some embodiments, the first terminal may also receive third information sent by the first device, where the third information is used to indicate that the first device has successfully received information related to the current service sent by the first terminal.

[0172] Optionally, in some embodiments, the first device may also send third information to the first terminal, where the third information is used to indicate that the first device has successfully received information related to the current service.

[0173] The following is an exemplary description of the present disclosure: Figure 7 As shown, it is a flowchart of an example of a communication control method proposed in the present disclosure, wherein the first device is a network device, and the method may include the following steps.

[0174] Step 701: The first terminal sends a power-on registration request to notify a network device that the first terminal supports a NAS signaling connection release function of a first communication card.

[0175] In some embodiments, after the first terminal is powered on or when registration is initiated in other scenarios, the first terminal sends the first terminal capability information to the network device to notify the network device that the first terminal supports the NAS signaling connection release function of the first communication card.

[0176] In some embodiments, the first terminal supports only a single communication card, and the first communication card is the single communication card supported by the first terminal.

[0177] Optionally, in some embodiments, the first terminal may support two or more communication cards, and the first communication card may be any one of the multiple communication cards.

[0178] Step 702: The network device notifies the first terminal that the network device supports the NAS connection release function of the first communication card.

[0179] In some embodiments, during the registration of the first terminal, the network device receives information that the first terminal supports the NAS signaling connection release function of the first communication card, determines that it also supports the NAS signaling connection release function of the first communication card, and notifies the first terminal that the network device supports the NAS connection release function of the first communication card.

[0180] Step 703: The first terminal recognizes that the first communication card can release the connection.

[0181] In some embodiments, the first terminal recognizes that the current service of the first communication card has been completed and there is no need to maintain the communication connection with the network device, and the network device successfully receives the information related to the current service sent by the first terminal. The first terminal can determine that the first communication card can release the connection.

[0182] Step 704: The first terminal sends a NAS signaling to notify the network device to initiate a connection release with the first communication card.

[0183] In some embodiments, the first terminal sends a service request (Service Request) to the network device, where the service request carries NAS signaling to notify the network device to initiate a connection release with the first communication card.

[0184] Step 705: The network device initiates a connection release with the first communication card.

[0185] In some embodiments, the network device receives NAS signaling from the first terminal and determines that there is no need to maintain the connection with the first communication card. The network device calls a connection release process to initiate connection release with the first communication card.

[0186] Optionally, in some embodiments, the first terminal receives a connection release with the first communication card initiated by the network device, so that the first communication card returns to an idle state.

[0187] like Figure 8 As shown, it is a flowchart of an example of a communication control method proposed in the present disclosure, which includes the following steps.

[0188] Step 801: The first terminal periodically checks the first communication card in a connected state.

[0189] In some embodiments, the first terminal periodically checks the first communication card in a connected state to timely identify that the first communication card can release the connection.

[0190] Step 802: Determine that the first communication card does not need to maintain connection with the first device.

[0191] For example, in some embodiments, the application processor AP of the first terminal may determine whether the first terminal still needs to maintain the NAS signaling connection, and notify the modem Modem of the first terminal of the determination result.

[0192] In some embodiments, the first terminal determines that the first communication card still needs to maintain connection with the first device, and then returns to step 801.

[0193] Step 803: Determine whether the current service of the first communication card is completed.

[0194] For example, in some embodiments, the modem of the first terminal may determine that all current services (eg, phone calls, text messages, signaling interactions, etc.) of the first communication card are completed.

[0195] In some embodiments, the first terminal determines that the current service of the first communication card has not been completed, and then returns to execute step 801.

[0196] Step 804: Determine whether the first device successfully receives information related to the current service.

[0197] For example, the first device is a network device. The first terminal receives a feedback message from the first device, and can determine, based on the feedback message, that the network device successfully receives all protocol data units (PDUs) on resource blocks (RBs) in a radio link control layer (Radio Link Control, RLC) of the first terminal.

[0198] In some embodiments, the first terminal determines that the first device fails to successfully receive information related to the current service, and then returns to execute step 801.

[0199] Step 805: Request to initiate connection release of the first communication card.

[0200] In some embodiments, the first terminal successfully executes step 802 to step 804, the first terminal determines that the first communication card meets the connection release condition, and the first terminal initiates a request to the first device to release the connection of the first communication card.

[0201] In other words, when any step in step 802 to step 804 fails to be executed, the first terminal may activate the timer to check and confirm the first communication card in the next cycle.

[0202] Therefore, this solution has the following beneficial effects:

[0203] The first terminal sends the first information to the first device, and the first device sends the second information to the first terminal, so that the first terminal can determine that the first device supports the connection release function of the first communication card, and the first device determines that the first terminal supports the connection release function of the first communication card to realize the connection release of the first communication card, so that the terminal supporting multiple communication cards can flexibly release the connection of any communication card, and the terminal supporting a single communication card can quickly release the connection of the communication card, thereby reducing the power consumption of the first terminal.

[0204] By determining that the first communication card meets the first condition, the connection of the first communication card is released under the first condition, so that the first terminal can put the first communication card into an idle state in time, thereby improving the flexibility of the first communication card connection release and reducing the power consumption of the first terminal.

[0205] By sending the fourth information to the first device to notify the first device that the first terminal is ready to release the connection of the first communication card, the first terminal and the first device can synchronously release the connection of the first communication card, thereby avoiding paging loss and ensuring the communication quality of the first communication card.
