Embodiment Construction

[0084] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0085] In order to realize data concurrency of two SIM cards in a dual-card terminal, the prior art provides a dual-card dual-pass technology. However, the realization principle of this dual-card dual-pass technology is: to establish two An independent electromagnetic wave link, when both SIM cards have service requirements, the two SIM cards comp...

Abstract

The invention provides a dual-SIM card communication method and equipment. The method comprises the following steps: a dual-SIM card terminal detects whether a data exchange request of a second SIM card sent by the network equipment is received when the dual-SIM card terminal performs the communication of a first SIM card through an electronic wave channel and the network equipment; if the dual-SIM card terminal receives the data exchange request of the second SIM card sent by the network equipment, a data packet of the second SIM card is exchanged with the network equipment through an ultrasonic channel. A condition of installing two sets of baseband chips, a radio frequency chip and a memorizer system on hardware support is avoided, and the cost and the power consumption of the dual-SIMcard terminal are reduced.

Description

technical field [0001] The invention relates to communication technology, in particular to a dual-card communication method and device. Background technique [0002] Dual-card dual-standby means that one terminal can insert two subscriber identification cards (Subscriber Identification Module, SIM card for short) at the same time, and these two SIM cards can be in standby state at the same time. How to make the data services of the two SIM cards run concurrently is one of the important research topics at present. [0003] The existing technology provides dual-card dual-pass technology, which can establish two independent electromagnetic wave communication links between the dual-card terminal and the base station, and the two subscriber identity identification module SIM cards pass through the two links respectively. An independent electromagnetic wave communication link communicates with the base station. However, this dual-card dual-pass technology needs to be supported b...
