Problems solved by technology

In the multi-card multi-standby mobile phone of the prior art, multiple SIM cards receive system messages independently. On the whole, multiple SIM cards receive their respective system messages multiple times, which increases system overhead and also causes network selection. and the time to switch cells is extended
[0005] The Chinese patent application with the application number 200710171901.7 discloses a method for finding a network when a dual-card dual-standby mobile phone is turned on, but it also does not solve the above problems

Embodiment Construction

[0036] In the multi-card mobile terminal in the prior art, during the power-on process and the standby state, multiple SIM cards receive system messages independently, which causes a large system overhead and a long time for network selection and cell switching at power-on.

[0037] In this technical solution, the system information received by any one of multiple customer identification cards is stored in the buffer for buffering, so that each customer identification card can directly obtain the system information from the buffer, avoiding multiple customer identification cards repeatedly The system overhead caused by receiving the same system message is relatively large, and the time for network selection and cell switching is reduced.

[0038] In order to make the above objects, features and advantages of the present invention more obvious and comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompany...

Abstract

The invention relates to a multi-card mobile terminal and a system message receiving method thereof. The system message receiving method comprises the following steps of: acquiring a system message received by any SIM (Subscriber Identity Module) card from a network; and storing the system message in a buffer zone so as to ensure thateach SIM card can acquire the system message from the buffer zone. The invention avoids the problem of excessive system expense caused by receiving the system message by multiple SIM cards for multiple times, and meanwhile, the time for network selection and cell switching is also reduced.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a multi-card mobile terminal and a system message receiving method thereof. Background technique [0002] With the rapid development of mobile communication technology, Global System for Mobile communication (GSM, Global System for Mobile communication) network has been widely used. GSM users may have multiple numbers, therefore, a large amount of mobile terminal equipment (for example, mobile phone) supports 2 or more than 2 subscriber identification module (SIM, Subscriber Identity Model) cards simultaneously, in order to satisfy user's many SIM cards standby simultaneously demand. [0003] Existing multi-card mobile terminals can be divided into two types: multi-GSM communication modules, each GSM communication module supports a SIM card, and realizes simultaneous standby of multiple SIM cards, wherein any SIM card can call in and call out, That is, a multi-card multi-sta...
