Description

Data attachment control method and device

technical field

The invention belongs to the technical field of communication, and in particular relates to a data attachment control method and device.

Background technique

The current dual-card dual-standby single-pass all-netcom mobile phone is equipped with only one antenna. When the secondary card or the main card is used for call services, neither the main card nor the secondary card can use data to initiate network requests. During card calls, users cannot access the Internet and send and receive multimedia messages.

If the main card or the secondary card is making a call, and the secondary card needs to use data to surf the Internet or receive MMS, then the secondary card will initiate a data attachment request. Since the call link is busy at this time, the attach request fails, and the secondary card will initiate a data attach request again. After the call ends, the data temporarily returns to the main card, but because the network request has already executed the phone mark, which is not the phone mark of the main card, the data of the main card cannot be restored. If the main card has no data, the user cannot access the Internet, and the user experience is poor.

The processor 104 may be an integrated circuit chip with signal processing capabilities. Above-mentioned processor 104 can be general-purpose processor, comprises central processing unit (Central Processing Unit, be called for short CPU), network processor (Network Processor, be called for short NP) etc.; Can also be digital signal processor (DSP), application-specific integrated circuit (ASIC), off-the-shelf programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components. Various methods, steps and logic block diagrams disclosed in the embodiments of the present invention may be implemented or executed. A general-purpose processor may be a microprocessor, or the processor may be any conventional processor, or the like.

The peripheral interface 105 couples various input and output units 106 to the processor 104 and the memory 102 . In some embodiments, the peripheral interface, processor, and memory controller may be implemented in a single chip. In some other instances, they can be implemented by independent chips respectively.

The input and output unit 106 is used to provide the user with input data to realize the interaction between the user and the communication device 100 . The input and output unit may be, but not limited to, a touch screen, a mouse, a keyboard, etc., and is used to output corresponding signals in response to user operations.

The display unit 107 provides an interactive interface (such as a user operation interface) between the communication device 100 and the user or is used to display image data for the user's reference. In this embodiment, the display unit may be a liquid crystal display or a touch display. If it is a touch display, it can be a capacitive touch screen or a resistive touch screen supporting single-point and multi-touch operations. Supporting single-point and multi-touch operations means that the touch display can sense simultaneous touch operations from one or more positions on the touch display, and hand over the sensed touch operations to the processor calculation and processing.

The SIM card interface circuit 108 is used for connecting the SIM card, and is installed at the card slot of the communication device 100 . The SIM card is a Subscriber Identification Module (SIM), also known as a Subscriber Identification Card or a Subscriber Identification Card. It is a smart card containing a large-scale integrated circuit, and the user stores important data and information of the user. The SIM card stores: integrated circuit card identity (Integrate circuit card identity, ICCID), MCC, MNC and temporary mobile subscriber identity code, user authentication key, location area identity code, etc. When the SIM card is inserted into the communication device 100, the SIM card is connected with the SIM card interface circuit.

The communication device provided in this embodiment is provided with dual SIM cards, and the dual SIM cards include a primary card and a secondary card.

When the communication device 100 needs to access a mobile communication network such as 2G, 3G or 4G, it mainly includes the following three processes:

(1) Data domain attachment. The purpose of the attach process is that the system determines whether to allow the communication device to perform data service access in the currently requested network routing area according to the subscription data of the communication device.

(2) PDP activation. The corresponding authentication permission is obtained through PDP activation, the corresponding IPv6 address is allocated, and the data channel between the communication device and the packet domain is established.

Taking a 3G network as an example, the PDP activation process is initiated by the communication device. The device first initiates a "Activate PDP Context Request" message to the SGSN, which carries access point name (Access Point Name, APN), quality of service and other information; the SGSN searches the HLR for the address of the corresponding GGSN according to the APN carried in the message, After obtaining the GGSN address, send a "Create PDP Context Request" to the GGSN; the GGSN can sign the terminal through local/DHCP/RADIUS and assign an IPv6 address or address prefix, as well as other parameters, such as QoS parameters, etc., and will authenticate The result and various parameters are carried in the "response to create PDP context request" message and sent to the SGSN, and the SGSN then sends the "accept activation of PDP context request" message to the terminal, and transfers the parameter configuration to the communication device, thus completing the PDP activation process .

(3) Business visits. After the PDP is activated, the IPv6 application data channel from the terminal to the packet domain of the 3G system has been opened.

Please refer to FIG. 2 , which is a flow chart of the steps of the data attachment control method provided by the first embodiment of the present invention. The process shown in FIG. 2 will be specifically described below.

Step S201, when receiving the indication information that the data attachment request of the secondary card in the preset environment fails, acquire the current call link status.

The communication device has only one antenna, so during the SIM card call, the data attachment request initiated by the main card or the secondary card will fail. This embodiment is mainly used to improve the technical problem that in the preset environment, when the secondary card fails to request data, the data cannot be restored to the primary card, resulting in the user being unable to access the Internet through the primary card. The preset environment is preferably that when the secondary card of the communication device is in the process of calling, when the secondary card needs to perform network requirements such as receiving multimedia messages, the secondary card needs to initiate a data attachment request. At this time, the data attachment request fails, and the data The attachment control device will receive indication information indicating that the data attachment request of the secondary card fails in a preset environment.

When any SIM card in the communication device is in a call state, the secondary card in the communication device initiates a data attachment request, for example, the secondary card needs to perform a data request for receiving a multimedia message. The secondary card needs to be connected to the mobile communication network, and will initiate a data attachment request.

After the first data attachment request fails, the secondary card will initiate a data attachment request again. In order to avoid the problem of high failure rate when the second data attachment request is initiated immediately after the data attachment request fails, it is preferable that the secondary card delays the first time period after the first data attachment request. A timer is set, and after the first data attachment request of the secondary card fails, the timer is started to delay for a first period of time. After the first period ends, the secondary card initiates the data attachment request again. Preferably, the first period of time is set to 30s, which can avoid the problem that the interval between two data attachment requests is short and easy to fail, and will not prolong the network connection process due to too long waiting time.

After receiving the indication information that the secondary card fails to initiate the data attachment request in the above-mentioned preset environment, acquire the current call link state to determine whether the SIM card of the communication device is in the call state. If the current call link state is the IDLE state, that is, the idle state, it means that the SIM card is not currently in a call. If the current call link state is either an IDLE state or a non-idle busy state, it means that there is a SIM that is currently in a call.

Step S202, when the state of the call link is idle, interrupt the data attachment request of the secondary card.

If the obtained current call link state is idle state, that is, there is no SIM card currently in the call, before the execution of the data attachment request being initiated by the secondary card, firstly perform the judgment operation of the subsequent network request state of the main card. The data attachment request being initiated by the secondary card may be interrupted to perform the operation of judging the status of the network request of the primary card. The judging operation of the network request status of the main card may also be inserted before the data attachment request initiated by the secondary card, so as to prevent the primary card from being blocked from connecting to the mobile communication network when the secondary card first connects to the mobile communication network.

Step S203, judging whether the main card initiates a network request.

If the main card initiates a network request, step S203 is executed to control the main card to initiate a data attachment request.

According to the above steps, in the non-call state, the data attachment request of the secondary card is interrupted. Judging whether the main card initiates a network request is to judge whether the user currently needs to access the Internet through the main card. The manner in which the data attachment control device determines whether the main card initiates a network request may include: determining whether the ddsPhoneId of the current main card is equal to the PhoneId that initiates the network request. If the ddsPhoneId of the current main card is equal to the PhoneId that initiates the network request, it means that the main card initiates the network request at this time. If the current main card's ddsPhoneId is not equal to the PhoneId that initiated the network request, it means that the main card has not initiated a network request at this time.

If it is determined that the primary card initiates a network request after the call ends, the primary card is controlled to initiate a data attachment request on the premise that the data attachment request already initiated by the secondary card is interrupted. The data attachment control device controls the master card to initiate a data attachment request, that is, to request the system to attach PS domain data services, and the system determines whether to allow the communication device to perform data services in the currently requested network routing area according to the subscription data of the communication device access. After the call ends, the data attachment request initiated by the secondary card is interrupted, and it is prioritized to determine whether the main card has a network request. When the main card has a network request, the main card is controlled to initiate a data attachment request, and priority is given to ensure that the user can pass through the main card after the call is over. Accessing the Internet without being blocked by the secondary card that has network requests during the call at the end of the call is the completion of the data attachment control process.

On the basis of the above embodiments, after the operation of judging whether the main card has network requirements, if the judgment result is that the main card has no network requirements, the network attachment control device may still control the main card to perform network attachment, so as to Waiting to meet or guarantee the user's demand for accessing the Internet through the main card. It can also control the secondary card to continue executing the interrupted data attachment request, so as to solve the network request of the secondary card in time. In other implementation manners, the data attachment control device may also end the data attachment control operation after judging that there is no network request from the main card, and the system will follow the sequence of network requests and data attachment requests from the main card or secondary card. The sequence or priority controls the sequential execution of data attachment requests by itself.

On the basis of the above embodiments, the data attachment control device determines whether the data attachment request is successful after controlling the main card to initiate a data attachment request. If the data attachment request is executed successfully, a data dialing process is initiated. If the data dialing process is executed successfully, execute the network request of the main card.

In the data attachment control method provided by the above-mentioned embodiments of the present invention, when the secondary card is in the process of calling and simultaneously initiates a data attachment request, and under the condition that the data attachment request fails, when the call link state is in an idle state, the secondary card initiates the call. Data attachment request, to determine whether the main card currently has a network request, if the main card has a network request, it will give priority to controlling the main card to initiate a data attachment request, to meet the user's needs to access the Internet through the main card, and will not be blocked by the secondary card that has a network request during the call. The card is attached to block when the call ends, which improves the user experience.

Please refer to FIG. 3 , which is a flow chart of the steps of the data attachment control method provided by the second embodiment of the present invention. The steps shown in FIG. 3 will be explained in detail below.

Step S301, when receiving the indication information that the data attachment request of the secondary card in the preset environment fails, acquire the current call link status.

Step S302, judging whether the call link state is an idle state.

If the call link state is not idle state, step S303 is executed.

If the call link state is an idle state, step S304 is performed.

The data attachment request initiated by the secondary card in the call state will not be executed, resulting in the failure of the data attachment request of the secondary card. After receiving the indication information that the secondary card fails to initiate the data attachment request, acquire the current call link state to determine whether the SIM card of the communication device is in the call state. If the current call link state is the IDLE state, that is, the idle state, it means that the SIM card is not currently in a call. If the current call link state is either an IDLE state or a non-idle busy state, it means that the SIM card is currently in a call.

Step S303, judging whether the state of the call link is converted to an idle state.

If the state of the talking link changes to an idle state, step S304 is performed.

In the process of judging the state of the call link in the above steps, if the current state of the call link is obtained as a busy state, the process of obtaining the state of the call link can be performed periodically to monitor whether the state of the call link is converted to idle Status, which is to judge whether the current call is over. It is also possible to wait to acquire the indication information of the release of the communication link, and determine that the status of the communication link is changed to the idle state when the indication information of the release of the communication link is acquired.

Step S304, interrupting the data attachment request of the secondary card.

If the acquired current call link state is an idle state, that is, no SIM card is in a call, firstly interrupt the data attachment request being initiated by the secondary card. In order to prevent the main card from being connected to the mobile communication network when the secondary card is first connected to the mobile communication network.

Step S305, judging whether the main card initiates a network request.

If the main card initiates a network request, step S306 is executed.

If the main card does not initiate a network request, perform step S307.

Step S306, controlling the main card to initiate a network request and initiate a data dialing process.

Judging whether the main card initiates a network request is to judge whether the user currently needs to access the Internet through the main card. The manner in which the data attachment control device determines whether the main card initiates a network request may include: determining whether the ddsPhoneId of the current main card is equal to the PhoneId that initiates the network request. If the ddsPhoneId of the current main card is equal to the PhoneId that initiates the network request, it means that the main card initiates the network request at this time. If the current main card's ddsPhoneId is not equal to the PhoneId that initiated the network request, it means that the main card has not initiated a network request at this time.

If it is determined that the primary card initiates a network request after the call ends, the primary card is controlled to initiate a data attachment request on the premise that the data attachment request already initiated by the secondary card is interrupted. The data attachment control device controls the main card to initiate a data request, that is, to request the system to attach PS domain data services, and the system determines whether to allow the communication device to perform data service access in the currently requested network routing area according to the subscription data of the communication device . After the call ends, the data attachment request initiated by the secondary card is interrupted, and it is prioritized to determine whether the main card has a network request. When the main card has a network request, the main card is controlled to initiate a data attachment request, and priority is given to ensure that the user can pass through the main card after the call is over. Accessing the Internet without being blocked by the secondary card that has network requests during the call at the end of the call is the completion of the data attachment control process.

The data attachment control device determines whether the data attachment request is successful after controlling the main card to initiate a data attachment request. If the data attachment request is executed successfully, a data dialing process is initiated. If the data dialing process is executed successfully, execute the network request of the master card.

Step S307, judging whether the secondary card initiates a network request.

If the secondary card initiates a network request, step S308 is executed to control the secondary card to initiate a network request.

If the secondary card does not initiate a network request, step S306 is performed.

Considering that after the end of the call, the data attachment request initiated by the secondary card fails, the secondary card may continue to initiate the data attachment request or give up the data attachment request. If it is determined that the primary card has not initiated a network request, It can be judged whether the secondary card currently initiates a network request. If the secondary card has initiated a network request, it can control the secondary card to initiate a data attachment request, and execute the current network request of the secondary card. If the secondary card does not initiate a network request, you can preferably configure the data that initiates the data attachment request to the primary card, and control the primary card to initiate a data attachment request, so as to give priority to satisfying the user's request to access the Internet through the primary card, and further improve the user experience. .
