Description

State switching method, mobile terminal, network equipment and communication system

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method for switching states.

Background

The paging technique may refer to a process initiated by the network side to find a specific mobile terminal and notify the mobile terminal to communicate with the network side. Paging a mobile terminal by a network can be divided into paging a mobile terminal in a P-state or paging a mobile terminal in an IDLE state, where the mobile terminal in the P-state includes a CELL paging state (CELL _ PCH) or a paging state (URA _ PCH) in a user registration area. The method includes the steps of paging a mobile terminal in a P state, paging a network side, wherein a paging message sent by the network side carries a universal mobile telecommunications system terrestrial radio access network temporary identity (UTRAN radio network temporary identity, URNTI), paging the mobile terminal in an IDLE state, and a paging message sent by the network side carries a Temporary Mobile Subscriber Identity (TMSI). When the mobile terminal is in P state, it can only process the paging message carrying URNTI identification issued by the network side, and when the mobile terminal is in IDLE state, it can only process the paging message carrying TMSI identification issued by the network side, so that only when the communication state of the mobile terminal and the network side is consistent, after the network issues the paging message, the mobile terminal can receive and process the paging message according to the carried identification.

At present, with the development of networks, a mobile terminal is developed from a single-card single standby to a dual-card dual standby (DSDS), a main body of the DSDS mobile terminal has two Subscriber Identity Module (SIM) cards, or two soft SIM cards (virtual SIM, corresponding to SIM information in a software form), or 2 pieces of SIM information in one SIM card, and hereinafter, two independent SIM cards, or two soft SIM cards, or one SIM card having two pieces of SIM information of a user are collectively referred to as two SIM cards. Thus, two SIM cards represent not only two hardware versions of the SIM card. Existing DSDS mobile terminals may have two modes of operation: the first is a single-pass mode, only one of the two SIM cards is in a data connection state, and the other SIM card is in a standby state, that is, the two SIM cards reuse the same Radio Frequency (RF) resource in the DSDS mobile terminal, and the two cards share one set of RF resource, so that resource preemption exists. The second is a two-pass mode, where both SIM cards can be in a data connection state, i.e. both SIM cards have independent RF resources. But most DSDS mobile terminals support only the first single-pass mode for technical and cost reasons.

When the main card of the DSDS mobile terminal is in an IDLE state because the RF resource is preempted by the auxiliary card, and the network side is not synchronized with the state of the DSDS mobile terminal at the moment, the network side can always send the paging message carrying the URNTI identifier, so that the main card can not process the received paging message carrying the URNTI identifier although acquiring the radio frequency resource, and the problem of missed call is caused.

Detailed Description

Embodiments of the present application will now be described with reference to the accompanying drawings, and it is to be understood that the described embodiments are merely illustrative of some, but not all, embodiments of the present application. As can be known to those skilled in the art, with the development of technology and the emergence of new scenarios, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

The embodiment of the application provides a state switching method, a terminal, a network device and a system, which can control a first user identity card to be kept in an idle state or switched to a paging state according to the occupation condition of radio frequency resources by a first user identity card and a second user identity card after the radio frequency resources of the first user identity card are occupied by the second user identity card, so that the communication state of the first user identity card is consistent with the communication state of the network device on the first user identity card, and the problem of missed calls in partial scenes is optimized. The following are detailed below.

The terms "first," "second," and the like in the description and in the claims of the present application and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Moreover, the terms "comprises," "comprising," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules not expressly listed or inherent to such process, method, article, or apparatus. The naming or numbering of the steps appearing in the present application does not mean that the steps in the method flow have to be executed in the chronological/logical order indicated by the naming or numbering, and the named or numbered process steps may be executed in a modified order depending on the technical purpose to be achieved, as long as the same or similar technical effects are achieved.

The technical scheme described in the present application can be applied to a third generation mobile communication partner project (3rd generation partnership project, 3GPP), Wideband Code Division Multiple Access (WCDMA), time division-synchronous code division multiple access (TD-SCDMA) communication system.

The SIM card may include a global system for mobile communications (GSM) Subscriber Identity Module (SIM), a User Identity Module (UIM) card, a Universal Mobile Telecommunications System (UMTS) subscriber identity module (UMTS) card, a dual mode card or an embedded international mobile subscriber identity module (eSIM) card, and the like, and may also include a lower subscriber identity card of other communication systems, and for convenience of description, the SIM card is only used as an example.

It should be understood that the embodiment of the present invention may also be applied to a multi-card multi-standby mobile terminal, and the embodiment of the present invention is described by taking a dual-card dual-standby mobile terminal as an example, where a dual-card dual-standby mobile terminal refers to a mobile terminal having two SIM cards, and the two SIM cards may be in a standby state at the same time, and both of the two SIM cards may implement communication services such as making/receiving a call, receiving and sending a short message. The dual-card dual-standby single-pass mobile terminal can support two numbers to be simultaneously online without increasing hardware cost, manual switching of a user is not needed, and only one of the two SIM cards can use radio frequency resources inside the mobile terminal. It should be noted that the two SIM cards here correspond to two users, and each user includes necessary information required for registering to the wireless communication network, such as one or more of encryption information, authentication information, and authentication information. The two SIM cards may be two physically independent hardware SIM cards, or a virtual soft SIM card (SIM information in software that may be stored in the memory of the mobile terminal), or two pieces of SIM information in software in one hardware SIM card. It can be understood that, multi-card multi-standby can be further developed on the basis of dual-card dual-standby, that is, the situation that a plurality of SIM cards are standby at the same time needs to be understood, multi-card multi-standby is very similar to dual-card dual-standby, a plurality of SIM cards also need to seize radio frequency resources, when one SIM card is in a data connection state, other SIM cards are in a standby state, or a plurality of SIM cards are in a standby state. Any two SIM cards in the multi-card multi-standby are in a dual-card dual-standby mode. Therefore, the multi-card multi-standby scenario is an extended application scenario or a specific application mode of dual-card dual-standby.

As shown in fig. 1, a schematic diagram of a composition structure of a communication system provided in the embodiment of the present application may include a mobile terminal and a network device, where the mobile terminal may include a first SIM card and a second SIM card, and at the same time, the first SIM card and the second SIM card only have one radio frequency resource capable of using the mobile terminal. Further, the mobile terminal has only one transmitting antenna, but has a plurality of receiving antennas. When the first subscriber identity card uses the transmitting antenna to transmit signals, the second subscriber identity card cannot use the transmitting antenna to transmit signals, but the second subscriber identity card can use the receiving antenna to receive signals. The wireless network device may be a base station or a base station controller for providing cellular wireless communication services to the mobile terminal, and the first SIM card and the second SIM card may be attached to different base stations.

When the radio frequency resource which is being used by the first SIM card of the mobile terminal is preempted by the second SIM card, the communication state of the first SIM card is switched from the paging state to the idle state, if the communication state of the network equipment to the first SIM card is not consistent with the communication state of the first SIM card at the moment, namely, the communication state of the network equipment to the first SIM card is kept in the paging state at the moment. When the first SIM card reacquires the radio frequency resource, the phone number corresponding to the first SIM card is called, and the first SIM card is in an idle state and cannot process the paging message carrying the URNTI identifier issued by the network device side, so that the first SIM card misses the call in such a scenario.

Fig. 1 is a diagram of a communication system according to an embodiment of the present application, where based on the system, after monitoring that a radio frequency resource is occupied by a second SIM card, a mobile terminal switches a communication state of a first SIM card from a paging state to an idle state, and then the communication state can be divided into two situations, where the first SIM card reacquires the radio frequency resource, and the second situation is that the first SIM card has not reacquired the radio frequency resource. Meanwhile, it should be noted that, after monitoring that the radio frequency resource is occupied by the second SIM, the mobile terminal may wait for a preset time and then switch the communication state of the first SIM card from the paging state to the idle state, and the state switching method provided in the embodiment of the present application will be specifically described below with respect to these situations.

The first case: and the mobile terminal monitors that the radio frequency resource is reacquired by the first user identity identification card.

In some embodiments, the first SIM card reacquires the radio frequency resource, and the first SIM card is in an idle state at this time, and the state switching process at this time is as shown in fig. 2.

Fig. 2 is a schematic diagram of an embodiment of a state switching method in the embodiment of the present application.

As shown in fig. 2, an embodiment of a state switching method in the embodiment of the present application includes:

201. and the mobile terminal monitors that the radio frequency resource is occupied by the second SIM card.

The method described in the embodiment of the present application is applied to a communication system, where the communication system includes a mobile terminal and a network device, the mobile terminal includes a first SIM card and a second SIM card, and only one of the first SIM card and the second SIM card can use a radio frequency resource of the mobile terminal at the same time. In this embodiment of the present application, when the first SIM card uses the radio frequency resource of the mobile terminal, the first SIM card is in non-idle communication with the network device, and when the first SIM card uses the radio frequency resource of the mobile terminal, the first SIM card is in paging communication with the network device. At this time, the mobile terminal monitors that the radio frequency resource is occupied by the second SIM card, and the reason for the occupation may be that the level of the service on the second SIM card is higher than the level of the service on the first SIM card or other reasons causing the second SIM card to occupy the radio frequency resource.

202. And the mobile terminal switches the communication state of the first SIM card from a paging state to an idle state.

Because the radio frequency resource in use by the first SIM card is preempted by the second SIM card, the mobile terminal switches the communication state of the first SIM card from the paging state to the idle state. The paging state includes a CELL paging state (CELL _ PCH) or a paging state in a user registration area (URA _ PCH). At this time, the communication state of the network device to the first SIM card is not consistent yet, and the communication state of the network device to the first SIM card is a paging state.

203. And when the mobile terminal monitors that the radio frequency resource is used by the first SIM card again, the mobile terminal updates the cell of the first subscriber identity identification card.

The mobile terminal monitors that the radio frequency resource is used by the first SIM card again, for example, in step 201, the first SIM card is on the internet, and the phone number corresponding to the second SIM card is called, because the priority of the phone service is higher than that of the internet service, the second SIM card preempts the radio frequency resource, in step 202, the phone service on the second SIM card is ended, the radio frequency resource is released, the first SIM card obtains the radio frequency resource again, and at this time, the communication state of the network device to the first SIM card is not consistent with the communication state of the first SIM card yet and is still in the paging state. When the mobile terminal monitors that the radio frequency resource is used again by the first SIM card, the first subscriber identity module card is subjected to cell update, and as an example, a specific process of cell update is given below, which may include the following steps: the mobile terminal starts the T316 timer and the OUT-OF-SERVICE area timer TI _ WAS _ CSEL _ OUT _ OF _ SERVICE. The T316 timer is a paging out-of-service area timer, and when the T316 timer runs, the first SIM card is allowed to enter an out-of-service area (OOS) procedure in a paging communication state. The out-of-service area timer is used for starting the OOS process when the out-of-service area timer is overtime. And when the T316 timer is running and the service-out area timer is overtime, clearing the cached internal information of the service-out area, and starting an OOS process to update the cell.

204. And if the cell is updated successfully, the mobile terminal switches the communication state of the first SIM card from the idle state to the paging state.

If the cell is updated successfully, the first SIM card and the network equipment acquire a link, and the mobile terminal becomes a paging communication state. If the cell update fails, it indicates that the first SIM card and the network device have not acquired a link establishment, and the mobile terminal maintains an idle communication state.

According to the method and the device for switching the communication state of the first SIM card from the idle state to the paging state, when the mobile device detects that the first SIM card acquires the radio frequency resources again, the first SIM card is switched from the idle state to the paging state, and when the mobile terminal detects that the radio frequency resources are used by the first SIM card again, the first SIM card is subjected to cell updating. Therefore, the communication state of the first SIM card is consistent with the communication state of the network equipment to the first SIM card and is in a paging state, and the problem of missed calls under the scene that the radio frequency resource of the first SIM card is preempted by the second SIM card is optimized.

Fig. 3 is a schematic view of a specific application scenario of the state switching method in the embodiment of the present application.

Fig. 3 illustrates a specific application scenario in the embodiment corresponding to fig. 2, as shown in fig. 3, a first SIM card in 3a is using traffic to surf the internet, and as shown in fig. 3b, when the first SIM card is surfing the internet, a phone number corresponding to a second SIM card is suddenly called. At the moment, the network equipment side is still in a paging state, because the telephone service has higher priority than the internet service, the first SIM card releases radio frequency resources, the data service is suspended, the first SIM card becomes an idle state, and the second SIM card seizes the radio frequency resources to carry out communication. As shown in fig. 3c, when the call of the second SIM card is finished for 10 minutes and 15 seconds, the radio frequency resource is released to the first SIM card, the first SIM card actively initiates a cell update action after taking the radio frequency resource again, if the cell update fails, the first SIM card is kept in an idle state, and if the cell update succeeds, the first SIM card changes to a paging state the same as that of the network device side. As shown in fig. 3d, the first SIM card is called, at this time, the paging message carrying the URNTI identifier is sent by the network device side, the first SIM card is called, and the first SIM card receives the paging in the paging state, because the communication state of the first SIM card and the communication state of the network device to the first SIM card are both in the paging state at this time, the first SIM card successfully processes the paging message carrying the URNTI identifier. It should be noted that 10 minutes and 15 seconds are listed in the examples of the present application only for illustration.

In some embodiments, the first SIM card reacquires the radio frequency resource, and the first SIM card is in a paging state at this time, and the state switching process at this time is as shown in fig. 4.

Fig. 4 is a schematic diagram of another embodiment of a state switching method in the embodiment of the present application.

As shown in fig. 4, another embodiment of the state switching method in the embodiment of the present application includes:

401. and the mobile terminal monitors that the radio frequency resource is occupied by the second SIM card.

Step 401 in the embodiment of the present application can be understood with reference to step 201 in the embodiment corresponding to fig. 2, and is not repeated here.

402. The mobile terminal starts a first timer.

The first timer is preset with a certain duration, and when the mobile terminal monitors that the radio frequency resource is occupied by the second SIM card, the first timer is started. The first timer may be an out-of-service timer, and the out-of-service timer is used for starting an out-of-service process after timeout.

403. And if the first timer is not overtime, the mobile terminal monitors that the radio frequency resource is used by the first SIM card again.

404. The mobile terminal controls the first SIM card to be kept in a paging state.

When the first timer is not overtime, the mobile terminal monitors that the radio frequency resource is used by the first SIM card again, the mobile terminal controls the first SIM card to be kept in a paging state, and when the first timer is overtime, the mobile terminal switches the communication state of the first SIM card from the paging state to an idle state.
