In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations 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 elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a schematic view of a scenario of a paging processing method provided in an embodiment of the present application, and as shown in fig. 1, the paging processing method includes a terminal device 101 and a network device 102, and the information transmission method provided in the present application may be applied to a 5G communication system, and may also be applied to other various wireless communication systems, for example: a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD), and the like.
The network device 102 in this application may be an evolved Node B (eNB or eNodeB) in LTE, or a relay station or an access point, or a base station in a 5G network, and is not limited herein.
Terminal device 101 may be a wireless terminal, which may be a device that provides voice and/or other traffic data connectivity to a user, a handheld device having wireless connection capability, or other processing device connected to a wireless modem. A wireless terminal, which may be a mobile terminal such as a mobile telephone (or "cellular" telephone) and a computer having a mobile terminal, e.g., a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, may communicate with one or more core networks via a Radio Access Network (RAN), and may exchange language and/or data with the RAN. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. A wireless Terminal may also be referred to as a system, a Subscriber unit (Subscriber unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), and a User Device or User Equipment (User Equipment), which are not limited herein.
According to the RRC release flow specified by the protocol: when receiving an RRC release message issued by a network device, an RRC layer needs to postpone execution of an operation of releasing connection from a connected state to an idle state, where the time for postponing execution of the RRC layer is 60ms, and the postponing of 60ms aims to reserve time to feed back a confirmation packet to the network device, so as to avoid that the terminal device cannot successfully send the confirmation packet to the network device due to too early release of connection, where the confirmation packet is used to indicate that the terminal device successfully receives the RRC release message issued by the network device.
However, in the process of switching from the connected state to the idle state, the terminal needs to synchronize the cell, and read a Master Information Block (MIB) and a System Information Block (SIB) of the camped cell, and since this process needs a certain time, if the paging time of the paging message sent by the network device falls within this time period, the paging message may be lost.
It should be noted that the main reason why the terminal device loses the paging message is as follows: when the network device receives the confirmation packet sent by the terminal device, the network device considers that the terminal device is in an idle state, that is, the terminal device is already resident in a suitable cell (suiteable cell), at this time, if there is a called service, the network device will issue a paging message to the terminal device, but actually, the terminal device really starts to perform an operation of converting from a connection state to the idle state after sending the confirmation packet, and the terminal device cannot guarantee normal reception of the paging message issued by the network device during the period before the terminal device is resident in the target cell.
In view of the above problems, an embodiment of the present application provides a paging processing method, where if a first paging time is after a first time, the first paging time is taken as a consideration factor, and if the first paging time is before the first time, a second paging time is taken as a consideration factor, thereby avoiding an operation of releasing an RRC connection at the paging time, and improving a receiving success rate of a paging message.
The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a first schematic flowchart of a paging processing method provided in an embodiment of the present application, where an execution main body of the method is a terminal device, and as shown in fig. 2, the paging processing method provided in this embodiment includes the following steps:
s201, receiving a Radio Resource Control (RRC) release message from the network equipment.
When the terminal device and the network device have no service interaction for a preset time, the network device sends an RRC release message to the terminal device in a connected state, and correspondingly, the terminal device receives the RRC release message from the network device. The preset duration may be determined by the network device, and this embodiment does not limit this.
S202, if the RRC release message does not carry the redirection instruction to the different system, acquiring a first paging time of a paging cycle at which the first time is located, wherein the first time is the time when the RRC release message is received.
The different system may be other communication systems, such as 2G and 3G, and the current system may be a communication system in which the terminal device is currently located, such as 4G and 5G. The redirection instruction includes the frequency point number of the redirection cell where the terminal device is to reside, and the redirection instruction to the different system includes the frequency point number of the redirection cell of the different system where the terminal device is to reside.
The redirection indication not carried to the foreign system in the RRC release message includes two cases:
firstly, the RRC release message does not carry a redirection instruction;
second, the RRC release message carries a redirection indication to the current system.
The paging cycle is a cycle for initiating paging, which is agreed by the network device and the terminal device, and each paging cycle includes a paging time, which indicates a time when the network device sends a paging message to the terminal device when there is a called service. In an exemplary scenario, when the terminal device receives the RRC release message, and performs a transition from the connected state to the idle state and camps on a suitable cell, the terminal device is in the idle state, and when there is a called service, for example: the network device sends the paging message to the terminal device at the latest paging moment so that the terminal device reestablishes the RRC connection to return to the connection state and can normally perform the called service.
In this embodiment, if the RRC release message does not carry the redirection instruction to the different system, a first paging time of a paging cycle where the first time is located is obtained, where only one paging time is in the paging cycle, that is, the first paging time, and the first time is a time when the RRC release message is received.
S203, judging whether the first paging time is after the first time.
If yes, go to step S204; if not, steps S205-S206 are executed.
S204, releasing the RRC connection according to the first time and the first paging time.
S205, acquiring a second paging time of the next paging cycle.
S206, according to the first time and the second paging time, the RRC connection is released.
Judging whether the first paging time is after the first time, if the first paging time is after the first time, which indicates that when there is a called service, the terminal device receives an RRC release message and does not receive a paging message at the first paging time, the first paging time may fall in the period of time that the terminal device receives the RRC release message and searches for a resident cell, and the paging message sent at the first paging time may be lost, and releasing the RRC connection according to the first time and the first paging time by taking the first paging time as a consideration factor.
If the first paging time is not after the first time, that is, the first paging time is before the first time, indicating that the terminal device has monitored the paging message in the paging cycle in which the first paging time is located before receiving the RRC release message, the second paging time of the next paging cycle is obtained, and the second paging time may fall within the period of time in which the terminal device receives the RRC release message and searches for the camping cell, and the paging message sent at the second paging time may be lost, the second paging time is taken as a consideration factor, and the RRC connection is released according to the first time and the second paging time. Wherein, there is only one paging time in the next paging cycle, i.e. the second paging time.
The paging processing method provided by the embodiment comprises the following steps: receiving a Radio Resource Control (RRC) release message from network equipment, if the RRC release message does not carry a redirection instruction to a different system, acquiring a first paging time of a paging cycle at which the first time is located, wherein the first time is the time when the RRC release message is received, judging whether the first paging time is after the first time, if so, releasing RRC connection according to the first time and the first paging time, and if not, releasing the RRC connection according to the first time and the second paging time. In the embodiment of the application, if the first paging time is after the first time, the first paging time is taken as a consideration factor, and if the first paging time is before the first time, the second paging time is taken as a consideration factor, so that the operation of releasing the RRC connection at the paging time is avoided, and the success rate of receiving the paging message is improved.
On the basis of the foregoing embodiment, fig. 3 is a flowchart illustrating a second method for processing paging according to an embodiment of the present application, and as shown in fig. 3, step S204 specifically includes:
s301, starting a timer according to the first time and the first paging time.
In this embodiment, to prevent the paging message from being lost, a timer is started according to the first time and the first paging time, the timer includes a first timer and a second timer, and the duration of the first timer is greater than the duration of the second timer.
The duration of the first timer is the sum of the duration of delaying the release of the RRC connection specified by the protocol and the duration of releasing the RRC connection to normally reside in the target cell, and the duration of the second timer is the duration of delaying the release of the RRC connection specified by the protocol.
The protocol specifies that the duration for postponing releasing the RRC connection may be 60ms, since the terminal needs to read MIB, SIB, etc. of the camped cell in the process of finding the target cell, this process may consume 100ms, which is non-fixed time and only one estimated time, that is, the duration for the terminal device to release the RRC connection to normally camp on the target cell may be 100 ms. It can be seen that the duration of the first timer may be 160ms, and the duration of the second timer may be 60 ms.
In one specific implementation, starting a timer according to a first time and a first paging time includes:
s3011, calculating to obtain a time difference between a first paging time and a first time;
s3012, judging whether the time difference is between the duration of the first timer and the duration of the second timer;
if yes, go to step S3013; if not, go to step S3014.
And S3013, starting a first timer.
And S3014, starting a second timer.
The duration of the first timer may be 160ms, and the duration of the second timer may be 60 ms. Calculating a time difference between the first paging time and the first time, and if the time difference is within a range of greater than or equal to 60ms and less than or equal to 160ms, starting a first timer, for example: the time difference is 70ms, a first timer is started, and the purpose of the step is to: when the first timer runs and a called service exists, the terminal equipment is still in a connected state and can successfully receive the paging message at the target paging time. Here, the time difference refers to an absolute value of the time difference.
If the time difference is not between the duration of the first timer and the duration of the second timer, the second timer is started, for example: the time difference is 40ms, the second timer is started. Wherein, the time difference is not included in the preset range and comprises two conditions:
first, if the time difference is smaller than the duration of the second timer, the second timer is started without extending the duration of the operation of deferring the execution of the RRC connection release, which is specified by the protocol. According to the protocol, during the operation of postponing 60ms execution of releasing the RRC connection, the terminal device is still in a connected state, and the terminal device can successfully receive the paging message at the target paging moment.
Secondly, the time difference is greater than the duration of the first timer, and since the terminal also needs to read the MIB, SIB, etc. of the resident cell in the process of searching for the target cell, this process may take about 100ms, so that it is not necessary to extend the duration specified by the protocol additionally and start the second timer. The reason is that: after delaying 60ms to execute the release of the RRC connection and normally residing in the target cell within 100ms, the terminal equipment is in an idle state and the residing is successful, the paging message at the first paging moment can be successfully received.
S302, in the running process of the timer, if a paging message for paging the terminal device is received from the network device, the timer is stopped, and the RRC connection is released.
In the running process of the timer, if a called service exists, for example: the network device may send a paging message to the terminal device at a first paging occasion, where the paging message includes identification information of the terminal device. Correspondingly, the terminal equipment receives the paging message from the network equipment, stops timing and releases RRC connection. The terminal equipment releases the RRC connection after receiving the paging message at the first paging moment, so that the loss of the paging message is prevented.
S303, in the running process of the timer, if the paging message is not received, when the timer is overtime, the RRC connection is released.
In this embodiment, in the running process of the timer, if the paging message is not received, the timer is waited for to be overtime, and the RRC connection is released when the timer is overtime.
In the running process of the timer, if the paging message is not received, two conditions are included:
when the time difference is between the duration of the first timer and the duration of the second timer, or the time difference is smaller than the duration of the second timer, in the running process of the timer, if there is no called service, the network device will not send a paging message to the terminal device, and correspondingly, the terminal device will not receive the paging message, wait for the timer to be overtime, and release the RRC connection when the timer is overtime.
Secondly, when the time difference is greater than the time length of the first timer, in the running process of the timer, even if there is a called service, the network device will send the paging message to the terminal device at the first paging time, and then the network device will not send the paging message to the terminal device in the running process of the timer, and correspondingly, the terminal device will not receive the paging message in the running process of the timer.
In steps S302 and S303, after releasing the RRC connection, the method further includes:
s304, residing in a target cell, wherein the target cell comprises a cell of the current system and a cell of a different system.
If the RRC release message does not carry the redirection indication, the target cell comprises a cell of the current system and a cell of a different system. Usually, the terminal device preferentially resides in an original cell of the current system, but can also reside in other cells of the current system when the signal quality of the original cell does not meet the residence condition; if the cell of the current system does not meet the residence condition, the system can also reside in the cell of the different system. The current system may be a 4G or 5G communication system, and the different system may be a 2G or 3G communication system.
If the terminal device resides in another cell of the current system, a Tracking Area Update (TAU) procedure is initiated to notify the network device of the location information of the cell where the terminal device currently resides because the TAC may be exchanged between the TAC and the TAC in the other cell.
If the RRC release message carries a redirection instruction to the current system, where the redirection instruction includes a frequency point number of a redirection cell of the current system where the terminal device is to reside, the target cell may be the redirection cell of the current system, and the target cell includes a cell of the current system, and may also reside in the target cell after the RRC connection is released.
If the target cell is the cell of the current system, step S305 may also be executed; if the target cell is a cell of a different system, step S306 may be further performed.
S305, in response to the paging message, sending a connection establishment request to the network device, where the connection establishment request is used to request to reestablish RRC connection with the network device.
S306, not responding to the paging message.
Specifically, if the target cell is a cell of the current system, a connection establishment request is sent to the network device in response to the paging message, the connection establishment request is used for requesting to reestablish RRC connection with the network device, and when the connection establishment is successful, the terminal device is switched from the idle state to the connected state, so that the called service can be performed normally.
If the target cell is a cell of other systems, the target cell is considered to be in an abnormal condition because: after the network device has instructed the terminal to go to the cell of another system, the terminal device should not send the paging message to the terminal device from the original system (current system), and the terminal device does not respond to the paging message.
The paging processing method provided by the embodiment comprises the following steps: starting a timer according to a first time and a first paging time, stopping the timer and releasing RRC connection if a paging message for paging a terminal device from a network device is received in the running process of the timer, releasing the RRC connection and residing in a target cell when the timer is overtime if the paging message is not received in the running process of the timer, wherein the target cell comprises a current system cell and a different system cell, and sending a connection establishment request to the network device in response to the paging message if the target cell is the current system cell, wherein the connection establishment request is used for requesting to reestablish the RRC connection with the network device, and the connection establishment request is not responded to the paging message if the target cell is the different system cell. In the embodiment, the RRC connection release is avoided from being executed at the paging time, so that the receiving success rate of the paging message is improved.
On the basis of the foregoing embodiment, fig. 4 is a flowchart illustrating a third exemplary flow of the paging processing method according to the embodiment of the present application, and as shown in fig. 4, step S206 specifically includes:
s401, starting a timer according to the first time and the second paging time.
The timer comprises a first timer and a second timer, the duration of the first timer is the sum of the duration of delaying the release of the RRC connection specified by the protocol and the duration of releasing the RRC connection to normally reside in the target cell, and the duration of the second timer is the duration of delaying the release of the RRC connection specified by the protocol.
In one specific implementation, starting a timer according to a first time and a second paging time includes:
s4011, calculating to obtain a time difference between the second paging time and the first time;
s4012, judging whether the time difference is between the duration of the first timer and the duration of the second timer;
if yes, go to step S4013; if not, go to step S4014.
S4013, starting a first timer;
and S4014, starting a second timer.
S402, in the running process of the timer, if a paging message for paging the terminal device is received from the network device, the timer is stopped, and the RRC connection is released.
S403, in the running process of the timer, if the paging message is not received, when the timer is overtime, the RRC connection is released.
In steps S402 and S403, after releasing the RRC connection, the method further includes:
s404, residing in a target cell, wherein the target cell comprises a cell of a current system and a cell of a different system.
If the target cell is the cell of the current system, step S405 may also be executed; if the target cell is a cell of a different system, step S406 may be further performed.
S405, responding to the paging message, and sending a connection establishment request to the network equipment, wherein the connection establishment request is used for requesting to reestablish RRC connection with the network equipment.
S406, the paging message is not responded.
The implementation process of steps S401 to S406 is similar to that of steps S301 to S306 in the embodiment of fig. 3, and is not described herein again.
The paging processing method provided by the embodiment comprises the following steps: starting a timer according to a first time and a second paging time, stopping the timer and releasing RRC connection if a paging message for paging a terminal device from a network device is received in the running process of the timer, releasing the RRC connection and residing in a target cell when the timer is overtime if the paging message is not received in the running process of the timer, wherein the target cell comprises a current system cell and a different system cell, and sending a connection establishment request to the network device in response to the paging message if the target cell is the current system cell, wherein the connection establishment request is used for requesting to reestablish the RRC connection with the network device, and the connection establishment request is not responded to the paging message if the target cell is the different system cell. In the embodiment, the RRC connection release is avoided from being executed at the paging time, so that the receiving success rate of the paging message is improved.
Fig. 5 is a fourth flowchart of the paging processing method according to the embodiment of the present application, and as shown in fig. 5, if the RRC release message carries a redirection instruction to a different system, the paging processing method may further include the following steps:
s501, if the RRC release message carries a redirection instruction to a different system, a second timer is started.
S502, in the running process of the second timer, if a paging message for paging the terminal device is received from the network device, the RRC connection is released.
Specifically, if the RRC release message carries a redirection instruction to the different system, the redirection instruction to the different system includes a frequency point number of a redirection cell of the different system where the terminal device is to reside. Because the network device does not send the paging message to the cell of the original system (i.e. the current system) under such a condition, that is, the network device already designates the redirected cell where the terminal device is to reside, and does not send the paging message to the cell of the current system, no additional time needs to be extended, and the terminal device starts a second timer according to the protocol specification, wherein the duration of the second timer is 60 ms.
Of course, if the paging message is received during the operation of the second timer, the RRC connection is released and resides in the redirection cell if the situation is considered as an abnormal situation. It should be noted that the terminal device only performs the RRC connection release and camp on the redirection cell designated by the network device, and does not respond to the paging message.
The paging processing method provided by the embodiment comprises the following steps: and if the RRC release message carries a redirection instruction to a different system, starting a second timer, and in the running process of the second timer, releasing the RRC connection if a paging message for paging the terminal equipment from the network equipment is received. And releasing the RRC connection in the running process of the timer. The operation of releasing RRC connection at the paging time is avoided, and the receiving success rate of the paging message is improved.
