Description

Dormancy control method and terminal

Technical Field

The present invention relates to the field of multimode communication, and in particular, to a sleep control method and a terminal.

Background

With the development of mobile communication technology, advanced cellular networks are being deployed around the world. Due to the introduction of the key technologies such as Orthogonal Frequency Division Multiplexing (OFDM) and multiple-Input multiple-Output (MIMO), the spectrum efficiency and the data transmission rate can be significantly increased by using the 4G related standard.

On the other hand, while improving network rate and frequency band utilization, the presence of a multimode terminal (a terminal with two subscriber identity modules, e.g., a dual-card dual-pass terminal) enables a user to establish a data service link while implementing a voice service standby.

However, the conventional terminal can only implement one Subscriber Identity Module (SIM) card as a main card for data service and voice service, and the other SIM card can only implement voice service standby, for which, a dual L communication architecture is proposed, and referring to fig. 3, in order to implement the dual L communication architecture, a Modem (Modem)2 is newly added to the original architecture, and the added Modem2 communicates with the Modem1 through a serial port (UART, universal asynchronous Receiver/Transmitter in the figure).

As shown in fig. 3, the SIM1 is used for internet access and telephone calls, and its services are supported by the Modem 1; before adding the Modem2, the SIM2 can only make calls through the Modem 1; after the Modem2 is added, the Modem2 reads the network authentication data of the SIM2 from the Modem1 through the serial port, and supports the network authentication data of the SIM2 through the Modem2, that is, supports the data service of the SIM2 through the Modem 2. The user data and signaling data in the Modem2 interact directly with the Application Processor (AP) through a Universal Serial Bus (USB) channel. Thus, the AP can simultaneously receive the internet access data of the SIM1 and the SIM 2. At this time, the data routing layer of the kernel layer performs algorithm processing, so that the APP internet surfing (whether downloading or uploading) can be performed through the SIM1 and the SIM2 at the same time.

In the dual L communication architecture, the Modem1 and the Modem2 both have the problem of being unable to sleep, which results in the problems of large power consumption and shortened endurance time of the terminal, and furthermore, the Modem2 is further unable to sleep adaptively according to the current battery power of the terminal.

Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

A communication system in which a mobile terminal according to an embodiment of the present invention is operable will now be described with reference to fig. 2.

For example, the air interfaces used by the communication systems include, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile communication System (UMTS) (in particular, Long Term Evolution (L TE, &lTtTtranslation = L "&lTt/T &gTtong Evolution), Global System for Mobile communications (GSM), etc. As non-limiting examples, the following description relates to CDMA communication systems, although such teachings are equally applicable to other types of systems.

Referring to fig. 2, a CDMA wireless communication system may include a plurality of Mobile terminals 100, a plurality of Base Stations (BSs) 270, a Base Station Controller (BSC) 275, and a Mobile Switching Center (MSC) 280, the MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290, the MSC280 is also configured to interface with the BSC275, which may be coupled to the Base stations 270 via backhaul lines, the backhaul lines may be configured according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame relay, HDS L, ADS L, or xDS L, it will be understood that the system as shown in fig. 2 may include a plurality of BSCs 275.

Each BS 270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS 270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS 270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each partition of a particular BS 270 may be referred to as a plurality of cell sites.

As shown in fig. 2, a Broadcast Transmitter (BT) 295 transmits a Broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295.

Based on the above hardware structure of the mobile terminal 100 and the communication system, various embodiments of the method of the present invention are proposed.

In the dual L communication architecture shown in fig. 3, both the Modem1 and the Modem2 have a problem of being unable to sleep, which may cause a large power consumption of the terminal overall, and the reason why both the Modem1 and the Modem2 are unable to sleep is that the serial port between the Modem1 and the Modem2 is unable to sleep, for this reason, the embodiment of the present invention proposes a serial port sleep scheme, which sleeps the serial port by sleeping a clock in the serial port.

Referring to fig. 4, fig. 4 is an architecture diagram of the Modem2 reading the network authentication data of the SIM2 from the Modem1, the left side of fig. 4 is the Modem2, the right side of fig. 4 is the Modem1, the Modem2 and the Modem1 communicate with each other via a UART serial port, and specifically, the Modem2 reads the network authentication data of the SIM2 from the Modem1 via the UART serial port.

For this reason, the embodiment of the present invention processes the UART driver layer in fig. 4, specifically, referring to fig. 5, fig. 5 is a framework diagram of the serial driver layer according to the embodiment of the present invention, wherein the framework of the serial driver layer includes a Data Access layer (DA L, Data Access L eye), a Hardware Abstraction layer (HA L, Hardware Abstraction L eye), and a Hardware (HW) layer, in an example, an N second (e.g., N is 5) timer may be set in the Data Access layer, and the Data Access layer may detect whether there is Data transmission in the current serial port, and if there is Data transmission, the serial port may remain in a transmission state without hibernation, and if there is no Data transmission, the Data Access layer notifies the Hardware Abstraction layer to drive the Hardware layer to call a power down mode supported by the serial port itself, so that the clock is in the sleep mode, which the serial port is also referred to as a power saving mode.

In the embodiment of the invention, the dormancy of the terminal (namely the dormancy of the CPU) adopts a voting mechanism, referring to fig. 6, the dormancy of the CPU is controlled by RPM, one NPA is a voting node, and when all the specified NPAs vote to dormancy, the RPM decides to enable the CPU to sleep, so that when the serial port in the embodiment of the invention sleeps, a vote is cast, and after other modules vote normally without problems, the CPU sleeps.

Fig. 7 is a first flowchart illustrating a sleep control method according to an embodiment of the present invention, and as shown in fig. 7, the sleep control method includes the following steps:

step 701: the method comprises the steps that a serial port is arranged between a first modem and a second modem, wherein the first modem is connected with a first communication card and a second communication card, and the second modem can acquire network authentication data of the second communication card from the first modem through the serial port.

In the embodiment of the invention, the first modem supports the data service and the voice service of the first communication card and supports the voice service of the second communication card; the second modem supports data traffic of the second communications card.

Referring to fig. 3, the first Modem is a Modem1, the second Modem is a Modem2, and the serial port between the first Modem and the second Modem is a UART. The first communication card is a SIM1 and the second communication card is a SIM 2.

As shown in fig. 3, the SIM1 is used for internet access and telephone calls, and its services are supported by the Modem 1; before adding the Modem2, the SIM2 can only make calls through the Modem 1; after the Modem2 is added, the Modem2 reads the network authentication data of the SIM2 from the Modem1 through the serial port, and supports the network authentication data of the SIM2 through the Modem2, that is, supports the data service of the SIM2 through the Modem 2. The user data and the signaling data in the Modem2 directly interact with the AP through the USB channel. Thus, the AP can simultaneously receive the internet access data of the SIM1 and the SIM 2. At this time, the data routing layer of the kernel layer performs algorithm processing, so that the APP internet surfing (whether downloading or uploading) can be performed through the SIM1 and the SIM2 at the same time.

Step 702: acquiring the electric quantity of a battery, and judging whether the electric quantity of the battery is lower than a preset threshold value.
