Embodiment 1

[0090] see figure 2 It is a schematic diagram of a communication architecture of a terminal in an embodiment of the present invention.

[0091] The communication architecture of the terminal 10 in the embodiment of the present invention includes: a radio frequency transmission module 13, a radio frequency management module 11, a first protocol stack 15, a second protocol stack 16, a TCP / IP protocol stack 18, a data application link service 19, and a data service module 40. The first virtual WAN transmission interface 171, the second virtual WAN transmission interface 172, the first SIM card 12, and the second SIM card 14.

[0092] Both the first protocol stack 15 and the second protocol stack 16 are Modem protocol stacks, which can simultaneously support multiple protocols such as LTE / WCDMA / GSM / TDSCDMA / CDMA / EVDO. Thus, the above-mentioned first technical standard and the second technical standard can be any wireless technical standard (for example, LTE, WCDMA, TDS-CDMA, GSM,...

Embodiment 2

[0131] see Figure 4 , the data communication method of the embodiment of the present invention includes the following steps:

[0132] Step 100: The first SIM card 12 performs network registration to reside in the PS domain and CS domain of the first network 30 through the first protocol stack. The second SIM card 14 performs network registration to reside in the PS domain and CS domain of the second network 32 through the second protocol stack.

[0133] In the embodiment of the present invention, when both the first SIM card 12 and the second SIM card 14 successfully register with the network, the terminal 10 enters into an idle mode (IDLE).

[0134] Since the terminal 10 has only one sending TX channel, if any SIM card fails to register with the network service, the registration timer (RegTimer) is started, and after the registration timer expires, the registration of the SIM card is completed again. However, within the timing of the registration timer, the radio frequency...

Abstract

The invention discloses a dual-card dual-standby terminal and a data communication method. The dual-card dual-standby terminal comprises a first SIM card, a second SIM card, a first protocol stack, a second protocol stack, a data service module and a TCP / IP protocol stack. The TCP / IP protocol stack comprises a first virtual WAN transmission interface and a second virtual WAN transmission interface. The first SIM card resides in a PS domain and a CS domain of a network through the first protocol stack. The second SIM card resides in a PS domain and a CS domain of a network through the second protocol stack. The first virtual WAN transmission interface and the second virtual WAN transmission interface are used for transmitting data of the first protocol stack and the second protocol stack respectively. The data service module is used for selecting the network where the first SIM card or the second SIM card belongs to establish a PS data service link so as to carry out data transmission. The terminal and the method have the following advantages that the SIM card can resides in a CS voice service and a PS data service simultaneously; transmission interruption and other problems generated because one network is abnormal can be avoided; a resource utilization rate is increased and a user experience is improved.

Description

technical field [0001] The invention relates to the field of mobile communication, and more specifically, to a dual-card dual-standby terminal and a data communication method. Background technique [0002] With the development of mobile network and data communication technology, users have higher and higher requirements on terminal data rate. On the other hand, while improving network speed and frequency band utilization, the emergence of multi-mode terminals (for example, DSDS, dual-card dual-standby terminals) enables users to establish dual-card voice services while on standby for dual-card voice services. data business link. [0003] However, in the existing DSDS terminal, when one of the two Subscriber Identity Module (SIM) cards uses data services, the other SIM card can only be used as a voice service standby. Therefore, if the communication network where the SIM card for the data service is located is interrupted, the communication quality deteriorates, etc., it wi...
