In an optional embodiment, the predetermined condition includes determining that the terminal is not in the flight mode, determining that the process other than the network lookup event is not completed, determining that the terminal is not locked, and determining that the personal identification password PIN is not required to be entered.

The following is an example in which the terminal of the Android system starts the network search process at the same time as starting the process other than the network search process.

In the embodiment of the present invention, a method for quickly finding a network based on an Android mobile terminal is provided, and a method for quickly finding a network by using a ril to directly trigger a modem to quickly start a network search and introduce a ril is provided. The delayed reporting mechanism ensures that the ril active reporting event of the system runs normally, so as to achieve the parallel processing of the network searching process and the Phone process, the time for booting the network is greatly improved.

In the solution of finding a network in the related art, after the ril is created, the network cannot be initiated immediately, but after the Phone process runs and connects to the rild, the request is made to set the modem to power on, and then the network process is started, which is delayed by several seconds to ten seconds. In the embodiment of the present invention, after the ril is created and judged that the flight mode is not turned on before the last shutdown, the modem is set to power on to start looking for the network in advance, and then the Phone process runs, connects the rild, and triggers the network state of the modem. The active reporting event such as the network event received in advance is notified to the Phone process in a delayed manner, and the Phone no longer initiates a power on finding a network request, thus completing the entire booting and quickly finding the network process. Among them, the above rild process is the daemon of ril, support and complete the implementation of ril, is a very important part of ril, in a sense, can be equivalent to ril. The Phone process is the Android system application framework layer program is implemented in Java language, rild is located in the lower layer of the Phone process between the application framework layer and the kernel, written in C language.

FIG. 7 is a flow chart of a quick network search according to an embodiment of the present invention. As shown in FIG. 7, the process involves two main parts: a ril self-starting power on mechanism and a ril delay active reporting mechanism, ril in FIG. 7. The self-starting power on, the modem to find the network, the ril delay active reporting and the Phone process, the rild connection forms a parallel processing effect, and the ril delay active reporting mechanism ensures that the message on the modem network side is not lost.

The following describes the ril self-starting power on mechanism:

In the fast boot network implementation method, when to enable ril to initiate power on is very important, this function can be controlled by an attribute, which is enabled by default. If the attribute is off, the boot speed mentioned in the patent is not implemented. Find a network solution, which can be well integrated with the native Android system. After the ril is started, the status of the attribute is determined. If it is the on state, then the current status of the terminal is determined. If the following three conditions are met, the ril is triggered to turn on the wireless operation (power on):

(1) The flight mode is not turned on;

(2) The Phone process has not yet functioned normally;

(3) The mobile phone is not locked and does not need to input the PIN code;

In this way, the power on process and the process of receiving the search process initiated by the Phone process are controlled by the lock so that they do not affect each other.

The following describes the ril delay active reporting mechanism:

For ril's own power on solution, since ril prematurely performs the wireless operation (the rild may not be running and initialized, and the phone process is not created yet), the modem then performs the active reporting event generated during the network search process. (How to ensure that the information is not lost before the application side and ril communication are established before the establishment of the communication between the application side and the ril is also a problem that must be considered. This is often the case in the native system, that is, the rild has already risen and reported the event but The framework has not been initialized yet, that is, the rild has not been connected yet. At this time, the events reported by ril are directly discarded in rild.

In this case, a delayed reporting mechanism needs to be utilized. The native system originally had such a mechanism but has many limitations. Based on this basis, the ril delayed active reporting has been completely modified. In ril, a global variable is created to save the number of events that need to be delayed and the number of records to be locked. When a certain process of ril needs to block an active report event, the report of this event will be added to this active report. In the linked list of event allocations, the number of lockups for this active escalation event is incremented by 1. How many processes need to block the number of locks that will be added to the active escalation event until all locked processes claim no need to add Locked, then the active report event that is cached in the linked list after the Phone process and ril are communicated will be reported to the framework in turn. For the cache of the active report event, it is processed in three cases:

(1) Events that are not reported to the Phone process are not cached and discarded directly;

(2) Exclusive cache of escalated events with exclusive conflicts, that is, the second cached report covers the first one, there is only one at most in the linked list, and the active status of the latest status information is always reported;

(3) In addition to the above two points, other active reporting events are fully cached;

Initialization in ril is to create this linked list, and all the active reporting events are suppressed. After rild receives the Phone process connection command, all active reporting events are all suppressed.

Through the above ril delay active reporting mechanism, for ril self-power on the solution, even if ril is initialized before the rild process is completed, the phone process has not been created before the power on, the information generated during the active reporting event will also be applied. The side is cached and not lost before establishing communication with ril.

Through the solution in the above embodiment, the time for booting the network can be effectively shortened, especially for the case where the SIM card is powered by the power on trigger (because the content on the card takes a long time), the improvement is more remarkable. And the introduction of the ril delayed active reporting mechanism ensures that even if the network is found before the Phone runs, the Phone will not miss the report information such as short messages that are generated in advance because the network is found.

It should be noted that each of the above modules may be implemented by software or hardware. For the latter, the foregoing may be implemented by, but not limited to, the foregoing modules are all located in the same processor; or, the modules are located in multiple In the processor.
