Detailed Description
The invention provides a communication method and a system of a dual-card dual-standby mobile phone, and the invention is further described in detail below in order to make the purpose, technical scheme and effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a preferred embodiment of communication of a dual-card dual-standby mobile phone according to the present invention, as shown in the figure, the method includes the following steps:
s100, when the sim1 card is in a normal conversation state, monitoring the network paging message of the sim2 card in real time, wherein the method specifically comprises the following steps:
s110, monitoring a network paging message of the sim1 card by the antenna 1 in real time, and when receiving the network paging message of the sim1 card, sending a paging response message of the sim1 card through a radio frequency resource on the antenna 1 to establish a call connection of the sim1 card;
specifically, the dual-card dual-standby mobile phone in the embodiment of the present invention includes only one baseband chip, one set of radio frequency resources, and two antennas (antenna 1 and antenna 2), where the antenna 1 is a main antenna, belongs to full-duplex communication, and can be used to receive and transmit radio frequency data; the antenna 2 is an auxiliary antenna, belongs to simplex communication and can only be used for downlink receiving;
further, in the use process of the dual-card dual-standby mobile phone, the antenna 1 is used for monitoring the network paging message of the sim1 card in real time, and when receiving the network paging message of the sim1 card, the antenna 1 sends a paging response message of the sim1 card through the radio frequency resource on the antenna 1 to establish the call connection of the sim1 card.
And S120, monitoring the network paging message of the sim2 card in real time through the antenna 2 when the sim1 card is in call connection.
Specifically, when the sim1 card occupies the radio frequency resource of the antenna 1 and establishes a call connection, the sim2 card uses the radio frequency downlink resource of the antenna 2 to monitor the network paging message of the sim2 card in real time.
S200, when receiving the network paging message of the sim2 card, sending a paging response message of the sim2 card through a radio frequency resource, and establishing a call connection of the sim2 card, which specifically comprises the following steps:
s210, when receiving the network paging message of the sim2 card, judging the network mode of the sim1 card;
specifically, when the sim2 card has an incoming call, that is, when the network paging network message of the sim2 card is received, the network mode of the sim1 card is determined first, and the paging response message of the sim2 card is sent in different ways according to different network modes of the sim1 card.
S220, when the sim1 card is judged to be in a GSM network mode, sending a paging response message of the sim2 card by utilizing the TDMA (time division multiple access) technical characteristic of a GSM physical link of the sim1 card; when the sim1 card is judged to be in a WCDMA network mode, starting a physical link uplink compressed mode of the sim1 card to send a paging response message of the sim2 card;
that is, when the sim1 card is determined to be in the GSM network mode, the paging response of the sim2 card is sent to the network by using the TDMA time division multiple access technology characteristic of the GSM physical link;
specifically, Time Division Multiple Access (TDMA) produces multiple slots on each frequency, with communication on different time slots; in the GSM system, the wireless interface uses a combination of tdma and fdma, users communicate on different frequency channels, and each frequency channel can be divided into 8 timeslots, each timeslot is a channel, so that at most 8 full-rate (or 16 half-rate) mobile clients can use one frequency channel simultaneously; further, when the network mode of the sim1 card in the call process is GSM, when the antenna 2 receives the network paging request of the sim2 card, the physical link of the sim1 card can be directly utilized to send the paging response message of the sim2 card to the network by using a specific time slot.
Further, when the network mode of the sim1 card is judged to be WCDMA, the Modem protocol stack starts an uplink compression mode, and responds to the paging response message of the sim2 card to the network by using the radio frequency resource of the antenna 1 through a compression gap;
specifically, the compression mode refers to a working mode that a mobile phone measures an inter-frequency or inter-system under the condition of not interrupting service so as to switch or adopt other operations in time according to the performance of a wireless channel, WCDMA mainly uses the adjustment of data rate and frame stream format to empty a measurement interval time slot TG L (TransmissionGap L ength) at one end in a wireless frame stream to finish the measurement of the inter-frequency or inter-system, further, in the invention, after the mobile phone receives a network paging message of a sim2 card, the uplink compression mode of a physical link of the sim1 card is started to obtain a measurement time slot, and then the network paging response message of the sim2 card is sent to a network by using the measurement time slot.
And S230, after the paging response message is successfully sent, prompting the subscriber to call the sim2 card through the upper layer of the mobile phone UI, and switching the radio frequency resource of the sim1 card to the sim2 card when receiving the call switching command of the subscriber to realize the call connection of the sim2 card.
Specifically, after the paging response message of the sim2 card is successfully sent, the ringing event of the network is received through the downlink of the antenna 2, and meanwhile, the sim2 card is reminded of receiving a call in a UI ringing mode, so that the user determines whether to answer the incoming call of the sim2 card; when a user determines to answer the incoming call of the sim2 card, namely when a call switching instruction of the user is received, the modem protocol stack sends a call disconnection request of the sim1 card to the network, ends the call of the sim1 card, simultaneously switches the radio frequency resource on the antenna 1 to the sim2 card, and sends a paging response message of the sim2 card through the radio frequency resource to establish the call connection of the sim2 card.
In general, CS circuit domain switching is a switching method for establishing a circuit connection between a sending end and a receiving end and maintaining the connection until the end of communication, and before communication, circuit switching needs to establish a physical path between two parties of communication, which is exclusively occupied by the two parties; therefore, in the existing dual-card dual-standby mobile phone, when the sim1 card performs a CS domain call, the sim1 card fully occupies the single-antenna radio frequency physical link transceiving resource, which causes that the network paging message of the sim2 card cannot be received or sent out, and finally causes that the sim2 card cannot be paged when the call comes, and the sim2 card misses the call.
In order to solve the problem that the sim2 card misses the telephone call, after the sim1 card establishes a CS domain call, the network mode of the sim1 card is judged firstly, and when the network mode of the sim1 card is judged to be GSM, according to the technical characteristics of GSM TDMA (time division multiple access), a sim1 card physical link sends a paging response message of the sim2 card to a network by using a specified time slot, so that the call connection of the sim2 card is established; and when the network mode of the sim1 card is judged to be WCDMA, starting an uplink compression mode of a sim1 card physical link, transmitting a paging response message of the sim2 card to the network by using a compression gap generated by the link compression mode of the sim1 card, and establishing the call connection of the sim2 card.
Further, when the user does not want to answer the call of the sim2 card in the call process of the sim1 card, the mobile phone receives the answer rejection command of the user, and at this time, the call request record of the sim2 card is stored for the user to inquire later, so that the call of the sim2 card is prevented from being missed.
Preferably, when the sim2 card is in a call connection state, the antenna 2 is switched to monitor the network paging message of the sim1 card, and the connection between the sim1 card and the network is maintained;
preferably, in the present invention, the dual-card dual-standby mobile phone is a GSM mobile phone or a CDMA mobile phone.
