The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

FIG. 1 is a schematic block diagram of a method for implementing dual-pass of a mobile terminal based on a set of radio frequency devices according to an embodiment of the present invention. As shown in FIG. 1 , the method includes:

Step 101: According to the time division multiplexing mode, the mobile terminal accesses the corresponding first communication network and the second communication network corresponding to the second communication card through a set of radio frequency devices respectively;

Specifically, the mobile terminal acquires pilot information, synchronization information, and paging information of the base station according to a time division multiplexing manner, and uses the pilot information, the synchronization information, and the paging information to access the radio equipment through a set of radio frequency devices. The first communication network and the second communication network are described.

Step 102: The mobile terminal performs a call period through the first communication network corresponding to the first communication card, and the base station monitors the call event of the second communication card in real time;

Further, when the mobile terminal uses the radio frequency device to make a call under the first communication network corresponding to the first communication card, the mobile terminal brings the second communication card into a sleep state.

Step 103: When monitoring the call event of the second communication card, the base station transfers the call event of the second communication card to the first communication card according to the call forwarding setting preset by the mobile terminal, so that the mobile terminal performs call selection.

The call forwarding setting is preset by the mobile terminal and sent to the base station before the call is made, and is used to transfer the call event of the second communication card to the first communication card that is in the call.

Specifically, when the base station detects a call event of the second communication card that has entered the sleep state, the base station sends, according to the call forwarding setting, a forward direction for notifying the first communication card that a new call event exists. /Update message to transfer the call event of the second communication card to the first communication card. After receiving the call event transferred by the base station, the mobile terminal can answer or reject the call. Calling, call switching can also be performed, that is, when the call is answered, the mobile terminal sends a reverse/update message for receiving the call event to the base station through the first communication network; when the call is rejected, The mobile terminal displays the call in the form of a missed call; when switching the current call, the mobile terminal sends a call to the base station for answering the transferred call through the first communication network, and causes the current call to enter the call waiting state. /Update message.

2 is a flow chart of a call service dual-passage according to an embodiment of the present invention. The premise of the present invention is that the mobile terminal has only one set of radio frequency devices, and two different types of cards inserted into the mobile terminal can be standby at the same time, as shown in FIG. 2, Includes:

After the mobile terminal is powered on, the mobile terminal recognizes two cards and reads information about the card number, for example: authentication information A-Key, password, MEID, carrier, country code, network code, etc.; then, the system Determining the communication network, for example: determining the selection of the CDMA network, or the GSM network, or the UMTS, etc., the pilot channel is captured, that is, the mobile terminal seizes the pilot signal sent by the base station, and generally selects the base station with the strongest pilot signal. The time limit is 15s, and the short-code synchronization between the mobile terminal and the base station is realized, and the synchronization channel is captured, that is, the mobile terminal receives the synchronization signal sent by the base station, captures the system configuration, timing information, and time synchronization. Here, three synchronization channel parameters are used: The offset parameter PILOT_PN of the pilot PN sequence, the long code state LC_STAYE and the system time SYS TIME, realize the synchronization of the mobile terminal and the base station, and finally complete the initialization process of the mobile terminal; finally, the two cards pass the time division multiplexing TDMA mode , register to the network, two cards are waiting at the same time, the specific implementation is: divide the working time of the RF device into multiple Time slices each time slice allocated to a different card. For example, in the TO period, the card acquires pilot information Pilot Channel of the base station, and the pilot information is used to acquire frequency and phase information of the base station, and synchronization information Sync Channel, where the synchronization information is used to acquire the frequency and phase of the base station. Information and paging information Paging Chanel; In the T1 time period, the card 2 acquires pilot information, synchronization information, and paging information of the base station. Since the time slice is divided shortly, two cards can be displayed on the mobile terminal interface to find the communication network at the same time, and the user cannot feel the network drop. As shown in Figure 3. In the second step, when the card initiates a call or receives a called party, the communication link is successfully established, and the card performs voice service.

The mobile terminal receives the base station channel assignment message (Extended Channel Assignment), the service connection message (Service Connect), and the service connection complete message (Service Connect Complete) from the base station, and the service negotiation process ends, and the call link is successfully established.

The third step, since only one set of radio frequency, the card case two dormant, receive paging signaling (Page / General Page) ₀ to less than the base station transmits two card

When the mobile terminal wants to have an incoming call or wants to receive a short message or the like, the base station sends the paging signaling to the mobile terminal. That is: If other mobile terminals want to page card 2, then the base station will send a Page/General Page page card 2, and the notification card 2 will have a message. Specifically, if the calling party, the mobile terminal will receive the access/origination signaling (Access/origination), the base station channel assignment message (Service Channel), the service connection message (Service Connect), and the service connection. Complete message (Service Connect Complete). If the called party is to receive the (Page/General Page) paging signaling, access/page response signaling (Access/Page Response), the base station channel assignment message ( Extended Channel Assignment), service connection message (Service Connect), and Service Connect Complete.

In the fourth step, the base station determines whether the mobile terminal has activated the call forwarding function, and if yes, performs the sixth step, otherwise performs the fifth step.

The mobile terminal can provide an interface option for the user. After the user selects the pre-selection, the following functions can be implemented: If the card is in the call service, the card 2 cannot receive the incoming call, and the incoming call of the second communication card can be transferred to the first communication. Card, in the same way, if the second communication card is in the call service, the first communication card cannot receive the incoming call, and the incoming call of the first communication card can be transferred to the second communication card, that is, the unreachable automatic transfer function is implemented. After the mobile terminal is set up, the call forwarding settings are reported to the base station for the base station to perform corresponding processing.

In the fifth step, the mobile terminal misses the incoming call. Step 6: If the base station determines that the mobile terminal has automatically preset the call forwarding setting for the second communication card, that is, pre-select the unreachable automatic transfer function, then if there is a second communication card in the state of the card, The base station will immediately send a forward/update message to the first communication card.

(Forward/Flash With Information), telling the first communication card that there is a new incoming call (Ring Call).

Step 7: After receiving the Forward/Flash With Information and the CM CALL EVENT CALLER ID in the first communication card call, the Call List and the number status are updated, and The call of the mobile terminal is displayed on the interface of the mobile terminal for the user to make a call selection. The Modem side of the mobile terminal reports the Call State Changed message (Call State Changed), notifies the display interface of the mobile terminal, and needs to refresh the interface, and the mobile terminal pops up the incoming call interface. Specifically, after receiving the CM CALL EVENT CALLER ID event, the mobile terminal updates the number information in the Call List list, if there is already a call (num_of_call_ids!=0), and there is another CM CALL EVENT CALLER ID If it is reported, then the Waiting flag of Waiting is set to 1 to inform the mobile terminal that there is a call waiting call. The specific steps are as shown in FIG. 4 .

In the eighth step, the user can choose to answer or reject the new call. If the user answers a new call, on the reverse link, send a reverse/update message to the base station (Reverse/Flash With Information). If the user rejects a new call, the notification bar shows a missed call. For a call waiting call, the user can switch the call through the Flash menu. At this time, the mobile terminal informs the base station to perform call switching by transmitting Reverse/Flash With Information on the reverse link.

The present invention also implements the dual-pass of the data service. Specifically, during the data service by the mobile terminal through the first communication network, the mobile terminal collects the service quality value of the data service in real time, and the service quality value and the service quality threshold are Comparing, if the service quality value is higher than the service quality threshold, the mobile terminal continues to use the first communication network to perform data service; otherwise, the mobile terminal starts the second communication network, and uses the second communication network Conduct data services. The specific steps are shown in Figure 5, including:

In the first step, after the mobile terminal is powered on, the two cards of different standards are successfully registered to the respective communication networks;

In the second step, the user initiates a data service by using a card-network mode;

In the third step, the mobile terminal can provide an interface option for the user. After the check box is selected, the following functions can be implemented: If the card initiates the data service, compare the indicators of the data service with the threshold, and if most of the indicators do not meet the standard, That is, if the service quality value is not higher than the service quality threshold, the fourth step and the fifth step are performed in sequence, otherwise the sixth step is performed;

In this embodiment, the following parameters are used to obtain various parameters, and a large number of values are counted and averaged to obtain threshold parameters:

The rate control parameter is obtained by using the multi-user diversity and the adaptive technology. The rate control parameter is the default coding type of the uplink GPRS link when the uplink default CS type is used, and is the uplink EDGE chain when the uplink default MCS type is used. The encoding type used by the road by default.

The power control parameters are obtained by using the front reverse high-speed power control and the forward SCH/FCH and SCH/DCCH control modes, and the power control parameters are set to correspond to the path loss when using the mobile terminal GPRS dynamic power control. The level of transmission power reduction of the mobile terminal in the relationship, and the expected received signal strength at the BTS side.

The supplemental channel SCH switching parameter is obtained by using a sliding window congestion control algorithm, and the supplemental channel SCH is responsible for the transmission of burst data.

Data SCH switching: During the process of initiating the data service, the parameter data variables such as the network communication speed and response time of the first communication card are continuously compared with the set threshold, and whether the current network speed is lower than the threshold and the response time is The threshold response time is exceeded, the packet loss rate is exceeded, and the maximum limit is exceeded.

Here, the parameter variable may further include a network side load, a frame error rate, and the like according to actual conditions and experience. All of the above parameters indicate the current data service situation. When more than half of the currently measured values of the set parameters do not meet the requirements, network switching can occur.

Further, the user selects the data service automatic switching function, and sets the data service network speed threshold to include: throughput, access duration, delay, packet loss rate, etc., in this embodiment, M-LWDF (modified largest wait delay first ) is adopted. ₀ Incoming users with poor channel status will wait in the queue of the base station, and once the waiting time exceeds the specified time limit, these packets will be discarded and will no longer be served.

In the fourth step, the current data service performance is extremely low, and the mobile terminal automatically turns off the current network mode data service;

In the fifth step, the mobile terminal enables another network mode for data service, that is, implements automatic data service switching function;

In the sixth step, the mobile terminal continues to use the current network mode for data services.

The present invention also provides a mobile terminal that implements dual-pass based on a set of radio frequency devices, and the carrier network supported by the mobile terminal includes but is not limited to CDMA, GSM, WCDMA, and LTE, and the mobile terminal includes the following modules:

a network access module, configured to enable the mobile terminal to access the first communication network corresponding to the first communication card and the second communication network corresponding to the second communication card by using a set of radio frequency devices of the mobile terminal;

a setting module, configured to preset, before the mobile terminal makes a call, the call forwarding setting for transferring a call event of the second communication card to the first communication card that is in a call, and sending the call forwarding setting to the base station ;

a call selection module, configured to: after the first communication card of the mobile terminal receives the call event of the second communication card transferred by the base station, if the mobile terminal answers the call, send the call to the base station to answer the call by using the first communication network The reverse/update message of the event, if the mobile terminal rejects the call, the call is displayed in the form of a missed call, and if the mobile terminal switches the current call, Transmitting, by the first communication network, a reverse/update message for receiving the transferred call and bringing the current call into a call waiting state;

a data collection module, configured to collect a service quality value of the data service in real time during a data service performed by the mobile terminal by using the first communication network;

a comparison module, configured to compare the service quality value with a service quality threshold, where the network switching module is configured to continue to use the first communication network to perform data service when the service quality value is higher than the service quality threshold Otherwise, the second communication network is activated, and the second communication network is utilized for data services.

In addition, the present invention also provides a system for implementing dual-pass based on a set of radio frequency devices, which enables dual-card mobile phones with only one set of radio frequency devices to implement dual-pass. The system includes a mobile terminal having the above modules, and a base station having the following modules:

a monitoring module, configured to monitor a call event of the second communication card in real time during the call by the mobile terminal through the first communication network corresponding to the first communication card;

a transfer module, configured to: when the call event of the second communication card is detected, the base station transfers the call event of the second communication card to the first communication card according to the call forwarding setting preset by the mobile terminal, so that the mobile terminal performs Call selection.

When two cards are inserted into the mobile phone, the network access module of the mobile terminal recognizes two cards and reads related card information, such as authentication information A-Key, password, MEID, carrier, country code (MCC), MNC, electronic The serial number (ESN), etc., and then based on the information, determine which carrier network the card belongs to. Since there is only one set of radio frequencies, the present invention can use the time division multiplexing (TDMA) method to ensure that both cards can find the network. The working time is divided into a plurality of time segments. For example, in the TO time period, the card acquires the pilot information, the synchronization information, and the paging information of the base station, so that the card 2 acquires the pilot information and the synchronization of the base station in the T time period. Information and paging information, because the split time is short, two cards can be successfully registered to the network at the same time on the interface, and the user does not feel that the network is dropped.

The mobile terminal performs a call service under the first type of network, that is, the card initiates a call or receives After the called party, the service channel is successfully established, the card performs a normal call. When the card is in a call, the protocol stack of the card 1 always occupies the radio device. At this time, the card two protocol stack is in a dormant state, and the card 2 cannot receive the paging information from the base station. In this case, the setting module of the mobile terminal automatically sets a call forwarding function to the card 2 under another network, and transfers the call of the card 2 to the card 1 of the first communication network. Then, if the terminal conducts a call service on the card one, that is, the card already has an active call.

(Foreground Call), and the monitoring module detects that there is an incoming call on the card 2. Since there is only one set of radio frequency, the incoming call of the card 2 is unreachable, and since the mobile terminal has automatically set the unreachable transfer to the card 2 in this case, the transfer module Send Forward/Flash With Information, tell the card one, there is a Waiting Call calling card. In the first communication network, when the card receives a new Ring Call, a call waiting situation is formed, and the user can receive or reject the incoming call through the call selection module, thereby realizing the dual-pass function under only one set of radio frequencies.

The device of the present invention can also realize the automatic switching function of data service, that is, if there is only one set of radio frequency equipment, if the first communication network is used for data service, the second communication network is in a dormant state. If the current data service speed is not ideal and the user wants to initiate data service with another network mode, then the device of the present invention eliminates the need for the user to manually switch to reselect the network.

The present invention sets a data service network speed threshold, and the threshold parameter includes: a network speed, a response time, and the like, and the threshold is obtained through a large number of statistical values of the platform, and then obtained according to a certain algorithm. When the user initiates the data service by using one of the networks, the comparison module of the mobile terminal continuously compares the current network speed with the threshold speed. If the current network speed is lower than the threshold speed, it is determined whether the current network speed response time exceeds the threshold setting time. Etc., compare the remaining parameters in turn. If the indicators show that the current network speed is really poor, the network switching module of the mobile terminal automatically stops the data service in the current network, automatically initiates a data service in another network, and implements data service dual-pass.

In summary, the present invention can set a dual-card automatic transfer function. After the function is successfully set, a set of radio frequency can be realized, and when there is an incoming call of the card two during a call, the call of the second call is transferred. Move to card one to realize dual communication of voice services. The invention can also set the automatic switching function of the data service. After the function is successfully set, the data service can be automatically switched in different network modes.

Although the invention has been described in detail above, the invention is not limited thereto, and various modifications may be made by those skilled in the art in accordance with the principles of the invention. Therefore, modifications made in accordance with the principles of the present invention should be construed as falling within the scope of the present invention. Industrial applicability
