Embodiment 1

[0071] The two SIM cards in this embodiment belong to different operators. Please see Fig. 3, Fig. 3 is a schematic flow diagram of updating the location areas of SIM cards belonging to different operators in the method for periodic location area updating of a dual-card dual-standby mobile phone with a single GSM communication module of the present invention.

[0072] Since the two SIM cards belong to different operators, the periodic location update parameters T3212 defined by the two operators are different. Therefore, the periodic location area update corresponding to each SIM is performed independently.

[0073] 1. Mobile phone test SIM 1 listens to BCCH and obtains cell parameter T3212.

[0074] 2. When SIM1 is in a normal state (not calling, switching, talking), start a periodic location update timer.

[0075] 3. The timer overflows and starts the normal location update process.

[0076] SIM 2 also completes the periodic location area update process according to the ab...

Embodiment 2

[0087] The two SIM cards in this embodiment belong to different operators. Although the two SIM cards belong to different operators, the periodic location update parameters T3212 defined by the two operators are the same. Therefore, the periodic location area update corresponding to the two SIM cards can be performed at the same time, and only one SIM card is needed The specific steps to obtain cell parameter T3212 from BCCH are as follows:

[0088] 1. The mobile phone tests that SIM1 monitors BCCH and obtains the cell parameter T3212.

[0089] 2. SIM2 obtains cell parameter T3212 from SIM1.

[0090] 3. SIM1 and SIM2 independently start their respective timers.

[0091] 4. When the timer overflows, each starts the normal location area update independently.

[0092] The above two SIMs are completely independent in processing the location area, and each completes its own processing flow.

[0093] The timer management process involved in Embodiment 2 is the same, and the two ...

Embodiment 3

[0102] The two SIM cards in this embodiment belong to the same operator respectively: the operation process is as shown in Figure 4, and Figure 4 is the method for periodic location area update of a dual-card dual-standby mobile phone with a single GSM communication module of the present invention. Schematic diagram of the process of updating the location area of ​​the operator's SIM card. Since the two SIM cards belong to the same operator, are physically in the same location, share the same set of communication modules, and the same antenna, the conditions of the cells corresponding to the two SIM cards must be the same. Therefore, only one SIM is required to obtain cell parameters T3212 from BCCH. The specific steps are as follows:

[0103] 1. Mobile phone test SIM 1 listens to BCCH and obtains cell parameter T3212.

[0104] 2. SIM2 obtains cell parameter T3212 from SIM1.

[0105] 3. SIM1 and SIM2 independently start their respective timers.

[0106]4. When the timer ove...

Abstract

The invention relates to a periodic location region updating method of a dual card dual standby mobile phone with a single GSM communication module. An antenna in the mobile phone is connected with a radio frequency circuit which is connected with a baseband processor which is also connected with a memorizer, other control circuits and an analog switch; two SIM cards are serially communicated on the analog switch. The method comprises (1) whether the two SIM cards belong to the same operator is judged; (2) if so, an SIM card is selected to obtain a cell parameter T3212 from a BCCH and the other SIM card obtains a cell parameter T3212 from the first SIM card; (3) if not, whether the periodic location updating parameters are identical is judged, if so, the step (2) is turned to, and if not, the periodic updating of the SIM card is carried out independently; (4) a timer is started by the SIM1 and the SIM2; (5) the location updating is independently started by the two SIM cards when the timer runs to overflow. When the periodic location region updating is achieved for the dual card dual standby mobile pone by the single GSM communication module, the application is convenient and the application range is wide.

Description

technical field [0001] The invention relates to a periodic location area update of a GSM mobile phone, in particular to a method for periodic location area update of two SIM cards in the same GSM terminal device, and a dual-card dual-standby mobile phone with a single GSM communication module for periodic location area update . Background technique [0002] The rapid development of personal mobile communication, many users have more than 2 phone numbers, corresponding to more than 2 SIM cards. In this case, you can choose to use two mobile phones, but it is very troublesome. Therefore, more and more users choose to use GSM mobile phones that support dual SIM. [0003] Currently, there are two technologies that support dual SIM: [0004] 1. Single GSM communication module, connect two SIM cards electronically or mechanically, but only one can work at the same time, and the other one is in shutdown state. That is, only one number can be used. [0005] 2. Dual GSM communic...
