Description

Communication processing method and device

Technical field

The embodiments of the present invention relate to a communication Internet technology, and in particular, to a communication processing method and apparatus.

Background technique

Dual SIM Dual Standby (DSDS) mobile phones use a single RF circuit, so when the secondary card makes a call, the primary card will drop. If during the secondary card call, the network registered by the primary card sends a paging message to the mobile phone requesting the mobile phone to initiate reattach, the primary card cannot receive the paging message and cannot respond to the network, so that the network considers the mobile phone primary card. The network has been dropped, and the mobile phone does not realize that it has dropped the network, thereby causing the mobile phone to be in an implicitly separated state from the network, referred to as an implicit separation state.

The implicitly separated state refers to the state in which the mobile phone thinks that it has registered to the network, but the network believes that the mobile phone is not registered on the network. When the mobile phone is in an implicitly separated state, when the mobile phone is called, the network side will not page the mobile phone because the mobile phone is not registered, so the calling party cannot call the mobile phone. For example, if the primary card of the DSDS mobile phone supports the Long Term Evolution (LTE) network, the secondary card supports the Global System for Mobile communication (GSM) network, and the primary card will be lost during the secondary card call. The network, at this time, if the network side sends a re-attach request during the main card drop, the mobile phone cannot respond, and the network side thinks that the mobile phone has dropped the network. When the secondary card is over, the primary card resumes the signal, and the mobile phone finds that the tracking area code (TAC) before and after the network is dropped. Track area update (TAU) is not initiated, that is, no The network will be re-attached, so the mobile phone is in an implicitly separated state. When another user calls the primary card, the primary card registration network does not initiate a call to the primary card of the mobile phone, but directly feeds the calling user back the message that the called user is not on the network. So that the phone's main card is called.

Summary of the invention

The embodiment of the present invention provides a communication processing method and device, which reduces the problem that the terminal is called out in the case of implicit separation, and improves the communication quality.

In a first aspect, an embodiment of the present application provides a method for processing communications, including:

Determining whether the terminal meets a preset trigger condition;

The network recovery includes at least one or more of the following: the terminal reacquires the radio resource after the radio resource is preempted, and the terminal reacquires the network signal after the network signal is lost.

The method for processing the communication provided by the first aspect, by determining whether the terminal meets the preset trigger condition, and if the terminal meets the preset trigger condition, after the terminal is disconnected from the network, the TAU is initiated before the next periodic TAU is initiated; It can be seen that when the terminal is disconnected from the network, it is not necessary to wait until the next periodic TAU time arrives, but the TAU can be initiated before the next periodic TAU is initiated after the network is restored, so that the terminal is called in the case of implicit separation. The problem of nowhere is to improve the quality of communication.

In a possible design, it is determined whether the terminal meets the preset trigger condition, including:

Determining whether the terminal reacquires the radio resource after the radio resource is preempted; or

detailed description

First, the process of reattaching the network involved in the embodiment of the present application is introduced:

The process of re-attaching the network is: the base station periodically sends a paging message to the terminal, and after receiving the paging message, the terminal sends a paging response message to the base station, and the base station sends the paging response message to the network, and then sends the reason to the network (case) a detach message of the field, wherein the assignment of the case field is reattach, which is used to indicate that the reason for sending the paging message is to require the terminal to initiate re-attachment, and then the base station performs other signaling interaction with the terminal to implement terminal re-attachment. The internet.

Secondly, the several nouns involved in the embodiment of the present application are explained:

The moment of initiating the re-attachment of the present application may be: the moment when the terminal determines that the base station sends the paging message to the re-attachment after the terminal is required to initiate the re-attach, or the reason that the terminal sends the paging message to the terminal to request the terminal to initiate The moment of reattachment. Since the time interval between the two is very small, it can be considered as the same moment.

The network recovery refers to: the terminal reacquires the network resource after the network resource is lost. Optionally, the network recovery includes at least one or more of the following: the terminal reacquires after the radio resource is preempted. The radio frequency resource and the terminal re-acquire the network signal after losing the network signal; for example, when the secondary card of the terminal is in a call, the radio resource of the primary card is preempted by the secondary card, and the primary card is dropped, when the secondary card stops talking, When the primary card reacquires the radio resource, the network of the primary card is restored; or, when the terminal enters the elevator, the network signal is not received and the network is dropped, and when the elevator is out, the network signal received by the terminal is re-received. The above situations are all related to the network recovery. Of course, the network recovery may include other forms. This is not limited in the embodiment of the present application; and the terminal can communicate with the network side device through the network after the network is restored. For example, The terminal registers the network, reattaches the network, and the like after the network is restored.

FIG. 1 is a schematic diagram of an application scenario of a method for processing communications according to an embodiment of the present disclosure. As shown in FIG. 1 , the method can be applied to a Long Term Evolution (LTE) network, where the scenario includes a terminal 1, a terminal 2, a base station 3, an LTE core network 4, and a Mobility Management Entity (abbreviation). MME) 5. Wherein, terminal 1 and terminal 2 are The network element device that is mainly involved in the embodiment of the present invention is a terminal and an MME, and the base station is mainly used to forward a communication message between the terminal and the MME. The processing method of the communication provided by the embodiment of the present invention is mainly applied to an implicitly separated scenario to solve the problem that the terminal is called unreachable. For example, when the DSDS mobile phone secondary card is called, the primary card is dropped, so that the primary card is called unreachable; or the DSDS mobile phone secondary card is doing high priority tasks such as Location update, and the primary card cannot obtain radio resources. In the case of a user, access to the elevator, underground garage and other lost network coverage, resulting in the mobile phone unable to respond to the network paging scenario, or dual SIM dual active (DSDA) mobile phones, or even single-card mobile phones may also occur The case of implicit separation.

FIG. 2 is a flowchart of a method for processing communications according to Embodiment 1 of the present application. The method mainly involves a specific process of initiating a TAU before the terminal periodically initiates a TAU after the terminal meets a certain triggering condition, and the execution subject of the method is the processing of the communication configured in the terminal. The device, as shown in Figure 2, includes the following steps:

Step 101: Determine whether the terminal meets a preset trigger condition.

In this embodiment, the preset triggering condition is used to trigger the terminal to initiate the TAU before the next periodic TAU is initiated after the network is restored. The preset trigger condition may be pre-configured according to actual requirements. For example, the trigger condition is set to be network recovery in advance, or the trigger condition is set to a time interval, etc., of course, the preset trigger condition may also be other trigger conditions. This is not limited in the examples.

Step 102: If the terminal meets the preset triggering condition, after the terminal is disconnected from the network, the TAU is initiated before the next periodic TAU is initiated.

In this embodiment, if the terminal meets the preset triggering condition, the TAU is initiated before the next time the TAU is periodically initiated after the terminal is dropped, and optionally, within a preset time period after the terminal is disconnected from the network. Initiating a TAU; optionally, the preset time period may be set according to actual requirements. For example, the preset time period may be set to 0s, and the terminal immediately initiates TAU when the network is restored; or, the preset time period is set. If it is 2s, the terminal initiates TAU within the period of 2 ms of network loss recovery. For example, if the preset trigger condition is network recovery, after the terminal loses the network signal, the TAU is initiated within a preset time period after the terminal acquires the network signal again; or, if the terminal is lost within a certain time interval In the case of the network, the TAU is initiated within a preset time period after the recovery of the terminal network, and the terminal initiates the TAU process to the MME. After that, the terminal can receive the paging message sent by the network and reattach the network to solve the situation that the terminal is in an implicitly separated state. The specific procedure for the terminal to initiate the TAU to the MME can be referred to the standard protocol "24301_Non-Access-Stratum (NAS) protocol for Evolved Packet System (EPS)-900", and details are not described herein.

The scheme of this embodiment will be described in detail below by taking a DSDS mobile phone as an example.

FIG. 3 is a schematic flowchart of a processing scheme of a DSDS mobile phone in the prior art. As shown in Figure 3, the secondary card occupies radio resources after the call starts at time (1), and the primary card loses radio resources at the time point (1), during the period from time (1) to time (3). That is, during the secondary card call, if the primary card registration network sends a paging message to the primary card at the time point (2), the primary card needs to reattach the network, but the primary card cannot receive the paging message because there is no radio resource, and thus cannot respond to the network delivery. The paging message, when the radio resource is released after the end of the secondary card call at the time point (3), the primary card acquires the radio resource at the time point (3), but because the TAC before and after the network is dropped, the terminal does not initiate the TAU, and the primary card is always in the In the implicitly separated state, the primary card still cannot receive the paging message sent by the network before the next periodic TAU is initiated, that is, during the period from time (3) to time (4), if the primary card is called The primary card will not be able to call until the next periodic TAU is performed at the time point (4), the primary card will reattach to the network, and the primary card will be called when the primary card is called after the time point (4).

FIG. 4 is a schematic flowchart of a processing scheme of a DSDS mobile phone according to an embodiment of the present application. As shown in FIG. 4, the secondary card occupies radio frequency resources after starting the call at the time point (1), and the primary card loses the radio frequency resource at the time point (1), during the time point (1) to the time point (3) during the secondary card call. If the primary card registration network sends a paging message to the primary card at the time point (2), the primary card is reattached to the network, but the primary card cannot receive the paging message because the radio resource does not receive the paging message, and thus cannot respond to the paging message sent by the network. After the time point (3), the radio resource is released after the call ends. After the primary card acquires the radio resource at the time point (3), it does not have to wait until the next periodic TAU time arrives, but at the time point (3) the main card acquires After the radio resource is started, the TAU is initiated before the next time the TAU is periodically initiated, so that the primary card is called normally. As shown in FIG. 4, it is assumed that the primary card initiates the TAU immediately after acquiring the radio resource, at the time point (3) to the time point. (4) During this time, the main card can also be called when it is called.

It should be noted that, in this embodiment, the dropped network refers to that the terminal loses network resources and cannot communicate with the network, for example, the radio resource of the terminal is preempted, or the network is abnormal. The terminal is caused to lose network signals and the like. Network recovery refers to the terminal acquiring network resources and communicating with the network. For example, the radio resources that the terminal is preempted are released, or the network is normal, so that the terminal acquires the network signal again. When the terminal is disconnected from the network, the terminal cannot communicate with the network. When the terminal network is restored, the terminal can communicate with the network. For example, the terminal performs network registration, receives an instruction sent by the network, and the terminal reattaches the network. In addition, when the terminal is offline, the terminal may be in a registered state or may be in an unregistered state. For example, if the terminal has already registered the network before the terminal drops the network, and the network is restored before the terminal receives the paging message next time, the terminal is in the network. If the network is registered before the network is disconnected, but the network does not recover before the time when the terminal receives the paging message sent by the network next time, the terminal does not receive the network due to the network drop. In the paging message, the terminal does not respond to the paging message. At this time, the terminal is in an unregistered state for the network side during the network disconnection.

The processing method of the communication provided in this embodiment determines whether the terminal meets the preset trigger condition. If the terminal meets the preset trigger condition, after the terminal is disconnected from the network, the TAU is initiated before the next periodic TAU is initiated; When the terminal is disconnected from the network, it is not necessary to wait until the next periodic TAU time arrives, but the TAU can be initiated before the next periodic TAU is initiated after the network is restored, so as to reduce the terminal being called in the case of implicit separation. The problem is to improve the quality of communication.

Further, on the basis of the embodiment shown in FIG. 2, an implementation manner of the step of “determining whether the terminal meets the preset triggering condition” includes: determining whether the terminal reacquires the radio frequency resource after the radio resource is preempted; Or determining whether the terminal reacquires the network signal after the network signal is lost; if the terminal reacquires the radio resource after the radio resource is preempted, or the terminal reacquires the network signal after losing the network signal, determining that the terminal meets the preset Trigger condition.

In this embodiment, the terminal re-acquires the radio frequency resource after the radio resource is preempted by the terminal; or determines whether the terminal reacquires the network signal after the network signal is lost, and if the terminal regains the radio frequency after the radio resource is preempted The resource, or the terminal re-acquires the network signal after the network signal is lost, and determines that the terminal meets the preset trigger condition, so that after the terminal returns to the network, the TAU is initiated before the next periodic TAU is initiated, optionally, regardless of A scene in which the radio resource of the terminal is preempted, or a scenario in which the terminal loses the network coverage. As long as the terminal reacquires the radio resource or the network signal, the TAU can be initiated immediately, so that the terminal is called normal. For example, for a DSDS mobile phone, the primary card LTE initiates a TAU immediately after the secondary card performs the voice call preemption radio resource, and ensures that the primary card is not in an implicitly separated state during the end of the secondary card voice call to the next periodic TAU, or The primary card initiates a TAU immediately after the network is dropped back to the network, ensuring that the primary card is not in an implicitly separated state after the network is lost and returned to the network until the next periodic TAU.

Optionally, determining whether the network signal is lost according to the network signal strength and the preset network signal strength threshold; if the network signal strength is lower than the preset network signal strength threshold, determining to lose the network signal; if the network signal strength is higher than the preset network again The signal strength threshold determines the reacquisition of the network signal. Certainly, the determination may be made in the prior art to determine whether the network signal is lost and/or the network signal is re-acquired.

Optionally, determining, according to the radio resource indication information, whether the radio resource is preempted; if the radio resource indication information indicates that the radio resource is occupied by the secondary card, determining that the radio resource is preempted; if the radio resource indication information indicates that the radio resource is not occupied, Make sure to reacquire the RF resources. Certainly, it can be determined by using other methods in the prior art to determine whether the radio frequency resource is preempted and/or re-acquired to the radio frequency resource, which is not limited in this embodiment.

If the terminal re-acquires the radio resource after the radio resource is preempted, or if the terminal reacquires the network signal after the network signal is lost, the terminal determines that the terminal meets the preset trigger condition, so that After the terminal is disconnected from the network, the TAU is initiated before the next periodic TAU is initiated. This not only reduces the problem that the terminal is called unreachable in the case of implicit separation, but also saves the signaling interaction burden between the terminal and the network side and the power consumption of the terminal. Simple and easy to implement.

FIG. 5 is a flowchart of a method for processing communications provided by Embodiment 2 of the present application. On the basis of the embodiment shown in FIG. 2, FIG. 5 relates to another implementation of the step of "determining whether the terminal satisfies a preset trigger condition". As shown in FIG. 5, the method includes the following steps:

Step 201: When the preset timer expires, obtain the first time interval.

In this embodiment, the preset timer is started when the terminal initiates the re-attachment. When the preset timer expires, the first time interval is obtained, where the first time interval is the last time the terminal initiates re-attachment. The time interval between the time of the terminal and the time when the terminal is disconnected from the network; the time period of the preset timer is the second time interval, and the second time interval is the time interval between the times when the terminal initiates reattachment twice.

Optionally, the obtaining the first time interval includes: recording the time when the last re-attachment is initiated is time 1. If the terminal drops the network before the time when the next re-attachment is initiated, the time of the network recovery is recorded as time 2, and The time interval between time 1 and time 2 is calculated to obtain a first time interval. Of course, the first time interval can be obtained by other implementations, which is not limited in the embodiment of the present application.

Step 202: Determine whether the first time interval is greater than the second time interval. If the first time interval is greater than the second time interval, determine that the terminal meets the preset trigger condition.

In this embodiment, the second time interval may be learned autonomously by the processing device of the communication, and the processing device of the communication continuously counts the time interval between the times when the two adjacent re-attachments are initiated, and records the time interval as the second time. time interval.

Optionally, the method for obtaining the second time interval may include: acquiring, by multiple times, a time interval between when the terminal initiates reattachment twice, and determining a minimum time interval among the obtained multiple time intervals as the second time. time interval. Or, optionally, determining a second time interval according to an interval between two times when the re-attachment is initiated before the preset timer is started, for example, when the terminal initiates the ith re-attachment, the preset timer is started. The time period of the preset timer (that is, the second time interval) may be: the interval between the time when the terminal initiates the i-1th reattachment and the time when the i th reattachment, i is a positive integer greater than 1. Alternatively, the sum of the interval between the time when the terminal initiates the i-1th re-attachment and the time of the i-th re-attachment and the preset interval (for example, 120s) may also be used. For example, when the terminal initiates re-attachment for the first time, the preset timer is started, and the time is recorded as time 1. The time period of the preset timer may be initially 1 hour by default; 2) the preset timer is not Before the timeout occurs, when the terminal initiates re-attachment for the second time, the preset timer is stopped, and the time is recorded as time 2, and the time interval 1 between time 2 and time 1 is calculated, and the time interval is 1 + the preset interval (for example, 120 s). And start the preset timer again as a new time period (where the time when the preset timer is started again can be regarded as still time 2); 3) when the terminal initiates reattachment for the third time before the preset timer is not timed out Stop the preset timer, record the time as time 3, calculate the time interval 2 between time 3 and time 2, and start the preset time again as the new time period with the sum of the time interval 2+ preset interval (for example, 120 s) (where the time when the preset timer is started again can be regarded as still time 3), and so on, the time interval between the two adjacent re-attachment times is continuously acquired, and the preset timer time is updated. week (I.e., the second time interval); I) does not expire before the timer preset, When the terminal initiates re-attachment for the ith time, the preset timer is stopped, and the time is recorded as the time i, and the time interval i-1 between the time i and the time i-1 is calculated, at a time interval (i-1)+preset interval. The sum of (for example, 120s) starts the preset timer again as a new time period (where the time when the preset timer is started again can be regarded as still the time i-1); i+1) after the preset timer is turned on During the time period, the preset timer is not stopped until the preset timer expires, because the terminal does not initiate the (i+1)th re-attachment (or the paging message sent by the base station). The first time interval is a time interval between a time i at which the terminal initiates re-attachment and a time when the terminal drops the network, and the second time interval is a time interval (i-1) + a preset interval (for example, 120 s). Sum. The purpose of adding a preset interval is to leave a certain redundancy time for the paging to be sent to the network. Otherwise, the time when the mobile phone initiates the TAU may be sent before the network sends a detach message.

In this embodiment, by determining whether the first time interval is greater than the second time interval, if the first time interval is greater than the second time interval (ie, the re-attachment should be initiated during the first time interval, but not initiated), determining the terminal The preset trigger condition is met. 6 is a schematic diagram of a first time interval and a second time interval in the present application. As shown in FIG. 6, time A is the time when the terminal initiates re-attachment for the ith time, and time B is the i+1th time that the terminal should initiate re-attachment. At the time of attachment, the time C is the time when the terminal is disconnected from the network, and the first time interval is the time interval between the time A and the time C, and the second time interval is the time interval between the time A and the time B, as shown in FIG. As shown, the first time interval is greater than the second time, that is, the terminal should initiate re-attachment at the time B at the time i, but because the terminal is offline, it is in an implicitly separated state, so that the terminal does not initiate a re-start at time B. Attached, therefore, it is determined that the terminal satisfies the preset trigger condition, so that the TAU is actively initiated before the next time the TAU is periodically initiated after the terminal drops the network recovery time C.

The method for processing the communication provided in this embodiment, when the preset timer expires, obtains the first time interval, and determines whether the first time interval is greater than the second time interval, and if the first time interval is greater than the second time interval, determining The terminal satisfies the preset triggering condition, so that the terminal initiates the TAU actively after the next time the TAU is periodically initiated after the network is restored, so that the terminal is called normal. It is obvious that the method does not need to initiate the TAU after each network recovery. The TAU is initiated when the preset trigger condition of the first time interval is greater than the second time interval, which reduces the signaling interaction between the terminal and the network, thereby reducing the network load and reducing the power consumption of the mobile phone.

Optionally, another step of the step of "determining whether the terminal satisfies a preset trigger condition" The current mode is as follows:

When the preset timer expires, the terminal reacquires the radio resource after the radio resource is preempted from the time when the re-attachment of the preset timer expires, or the terminal reacquires after the network signal is lost. The network signal) determines that the terminal satisfies the preset trigger condition.

The preset timer starts at the time when the terminal initiates the re-attachment, and the time period of the preset timer is the second time interval, where the second time interval is between the time when the terminal initiates reattachment twice. time interval. For the manner of starting the timing of the preset timer, refer to the relevant part in the foregoing embodiment, and the manner of obtaining the second time interval. For the manner of the method for “acquiring the second time interval” in the foregoing embodiment, the Narration.

In this embodiment, when the preset timer expires, the network lost event occurs when the terminal loses the network signal from the time when the last re-attachment to the preset timer expires. The device may not initiate a re-attachment during the period when the last re-attachment to the preset timer expires. However, the terminal does not receive the paging message sent by the base station, so that the terminal is in an implicitly separated state. Therefore, it is determined that the terminal meets the preset trigger condition, so that the terminal periodically initiates the TAU after the network is restored. Previously, the TAU was actively initiated to restore the terminal called. The event of a network loss is an event that the terminal cannot access the network when the terminal enters and exits a scene that cannot be covered by a network such as a garage or an elevator. The non-stealing frame task event is an event in which the radio resource cannot be occupied by the main card when the terminal sub-card uses the radio resource. For example, when the secondary card uses voice calls, receives or sends short messages, location area updates, routing area updates, etc., the primary card cannot use radio resources.

Optionally, the method of determining whether the terminal meets the preset triggering condition may also be implemented in other implementation manners, which is not limited in the embodiment of the present application.

Further, on the basis of the embodiment shown in FIG. 5, the method further includes: if the TAC corresponding to the terminal changes, stopping the preset timer, and re-acquiring according to the time when the terminal initiates re-attachment in the updated TAC. The second time interval.

In this embodiment, a Tracking Area refers to a set of multiple cells (Cells), a TAC is a code of each tracking area, and a TAC is generally used to track a real-time location of a UE. When the TAC corresponding to the terminal changes, the real-time location of the terminal changes, and different tracking is performed. The mechanism for the base station to send a paging message to the terminal (or initiate re-attachment) may be different. Therefore, when the area where the terminal is located changes, the second time interval needs to be re-acquired. For example, the period in which the Beijing mobile base station sends a paging message to the terminal (or initiates re-attachment) is 1 hour. When the terminal is from Beijing to Shanghai, the Shanghai mobile base station sends a paging message to the terminal (or initiates a new The period of attachment is 1.5 hours. Therefore, the terminal needs to re-learn the second time interval according to the time of receiving the paging message (or initiate re-attachment), and start the preset timer with the new second time interval as a cycle. Re-determine whether the terminal is implicitly separated.

Further, on the basis of the embodiment shown in FIG. 5, after the terminal is disconnected from the network, the method further includes: restarting the preset timer after initiating the TAU before the next periodic TAU is initiated.

In this embodiment, after the TAU is initiated, the terminal restarts the preset timer to perform a new round of detection, that is, re-determines whether the terminal meets the preset trigger condition.

Optionally, on the basis of the embodiment shown in FIG. 5, the network registered by the terminal is a long-term evolution LTE network, and the method further includes: when the preset timer expires, if the LTE network is in a service state, restarting the preset timing Device.

In this embodiment, when the preset timer expires, if the LTE network is in the main mode service state, no processing is performed, and the timer is reset. The main mode service state refers to that the LTE network is in a working state, that is, when the LTE network is in a working state, when the preset timer expires, the preset timer may be restarted. When the preset timer expires, the LTE network is in slave mode, and no processing is performed, and the preset timer is not restarted. The slave mode means that the current master card supports the LTE network, when the master card works in GSM or In the case of the Wideband Code Division Multiple Access (WCDMA) system, if the preset timer expires, no processing is performed and the preset timer is not restarted.

It should be noted that the method of this embodiment can be applied to an LTE network. For example, when the primary card supports the LTE network standard, if the primary card is covered by the LTE network, the LTE network supported by the primary card is in a normal working state, and the terminal can receive the paging message sent by the network. When the preset timer expires, Restart the preset timer and restart to determine whether the terminal is down and the network is restored, and whether TAU needs to be initiated. When the primary card supports the LTE network standard, if the primary card is a network other than the LTE network, for example, the primary card is a GSM network or a WCDMA network coverage, the LTE network supported by the primary card is in an abnormal working state, and the primary card is Other network coverage except LTE network If the paging message sent by the network is not received, the preset timer is meaningless to other networks except the LTE network. Therefore, no processing is performed and the preset timer is not restarted.

Optionally, on the basis of the embodiment shown in FIG. 5, the network registered by the terminal is a long-term evolution LTE network, and the method further includes: if the LTE network transitions from the service state to the standby state, restarting the preset timer.

In this embodiment, if the LTE network is switched from the service state to the standby state, the preset timer is restarted regardless of whether the preset timer expires, so as to ensure that the LTE network can be correctly and timely solved under various states of the LTE network. The terminal is in an implicitly separated state, causing the call to be unreachable.
