Problems solved by technology

However, there are also shortcomings. Existing terminal products can only support one of the access methods, that is, the machine-card integrated access method or the machine-card separation access method
Once operators and users select a certain terminal product, its corresponding access method is also bound by default, and the access method cannot be changed during use, which brings inconvenience to operators and users who want to change the access method

no. 1 example

[0036] This embodiment takes the CDMA terminal as an example, and mainly realizes the identification and conversion of the access mode by detecting whether a UIM card is inserted in the wireless terminal. It can also be used for the SIM card of the GSM terminal, etc. These cards are collectively referred to as the subscriber identification module in this paper .

[0037] As shown in Figure 1, after the wireless terminal of this embodiment is turned on, the identification process of the access mode by the system (including the operating system and the application program) in the terminal includes the following steps:

[0038] Step 101, after booting, the system is initialized, the hardware status is detected, and it is judged whether a UIM card is inserted in the UIM card holder of the terminal, if yes, perform step 102, otherwise, perform step 103;

[0039] Step 102, the system runs according to the set machine-card separation and access flow, and ends;

[0040] Step 103, the...

no. 2 example

[0044] This embodiment records the user's setting of the wireless terminal's access mode by setting and saving the state value of the mode switch, and uses the set access mode to run after booting, and prompts the user when the set mode cannot be run.

[0045] As shown in Figure 2, the method of this embodiment includes the following steps in identifying and converting the access mode when the terminal is turned on:

[0046] Step 201, the system is initialized after starting up, and it is judged whether this power-on process is the first power-on of the wireless terminal after leaving the factory, if yes, perform step 202, otherwise, perform step 203;

[0047] Step 202, the system prompts the user to select the access mode, and saves the mode switch state value corresponding to the selected access mode in NV (Non Volatile Memory);

[0048] In this step, the system can also load the default mode change switch state value set by the manufacturer, and write the mode change switch...

no. 3 example

[0063] In this embodiment, the operator sets the state value of the mode switching switch, and controls the mode switching to a certain extent.

[0064] As shown in Figure 3, the identification and conversion process of the access mode when the method of this embodiment is turned on includes the following steps:

[0065] Step 301, the system is initialized after booting, and it is judged whether this power-on process is the first power-on of the wireless terminal after leaving the factory, if yes, perform step 302, otherwise, perform step 303;

[0066] Step 302, the system loads the default mode switch status value set by the manufacturer, and writes the mode switch status value into NV;

[0067] Step 303, the system reads the state value of the mode switch from the NV parameters, and determines the corresponding access mode, if it is the "machine-card separation access" mode, execute step 304, if it is "machine-card integrated access" mode , execute step 307;

Abstract

The disclosed recognition and switch method for wireless terminal machine-card integral accessing and separated accessing modes comprises: system decides whether there is card in terminal during initiating, yes to run separated accessing process, or else runs the integral accessing process; the switch is executed by inserting or pulling out card; or, system reads stored mode switch on-off state value during initiating and runs corresponding process of different access mode, or notifies user to modify access mode by special software. This invention can meet both user and provider requests.

Description

technical field [0001] The present invention relates to wireless communication terminal products, more specifically, to the smooth conversion of two access modes of integrated machine-card and separated machine-card of wireless communication terminal products of CDMA (Code Division Multiple Access) and other standards. Background technique [0002] Since the CDMA network was put into commercial use in 1995, CDMA terminal products have undergone a transformation from a machine-card-integrated access mode to a machine-card-separated access mode. Today, both access modes are widely recognized and commercialized on a large scale. In the existing machine-card integrated access mode, its host (terminal) and card (including access parameters: ESN (Equipment Sequence Number) / IMSI (International Mobile Subscriber Identity) / AKEY (Authentication Key) key) / PRL (Preferred Roaming List preferred roaming list), etc.) correspond to each other and cannot be used independently. When the opera...
