Description

Technical Field

[0001] The present application belongs to the field of communication technology, and in particular, relates to a mobility process processing method and related equipment. Background Art

[0002] With the development of communication technology, communication systems are becoming more and more perfect. In the current communication system, during the process of establishing an Internet Protocol Multimedia Subsystem (IP Multimedia Subsystem, IMS) service, if a mobility process occurs, the terminal will execute the mobility process, which will cause the high-level signaling to not be sent, resulting in the interruption of the IMS service. For example, when performing voice services on the New Radio (NR), you can perform an Evolved Packet System (EPS) fallback from NR to the LTE network for IMS voice calls. In this process, there is a problem of failure to establish a voice call.

[0003] For the scenario of switching from NR to Long Term Evolution (LTE) for a call, for example, during the IMS voice process of the calling terminal and the called terminal establishing the signaling plane, the calling terminal will send an update to inquire about the status of the called terminal. Since it has not switched to the LTE base station, the called terminal will reply with a 200OK (remote sendrecv / local none) message, which means that the called terminal is not ready. However, this message may not be sent successfully due to the switch. After the switch is completed, the prerequisite (precondition) of the called terminal is met, and the called terminal will send a 180ring message to the IMS to tell the IMS that the precondition has been met. At this time, the IMS may resend the last update message to inquire about the status of the called terminal. If the IMS still receives the last response message and determines that the precondition is not met, the call establishment will fail.

[0004] Therefore, in the prior art, there is a problem that the terminal performs a mobility process, resulting in the interruption of transmission of part of the data or signaling. Summary of the invention

[0047] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0048] About EPS Fallback.

[0049] NR does not provide voice services in the early stage. When the fifth generation mobile communication technology (5G) base station (gNB) establishes an IMS voice channel on NR, a handover is triggered. At this time, the gNB initiates a redirection to the 5G Core Network (5GC) or supports an inter-radio access technology (inter-RAT) handover request, and falls back to the LTE network, which is provided by Voice over Long-Term Evolution (VoLTE). Falling back to the LTE network can also be understood as falling back to the LTE network.

[0050] The process of falling back is as follows Figure 2 As shown in the figure, specifically, the terminal resides in 5G NR. After initiating a voice call, both voice and data fall back to 4G LTE. Voice channels often require NR to continuously optimize the network to achieve good voice quality and low UE power consumption. By choosing this technology, operators can focus on developing data services in the early stage of 5G NR, and then evolve to VoNR after NR network coverage and optimization.

[0051] The mobility process processing method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0052] See also Figure 3 , Figure 3 is a flow chart of a method for processing a mobility process provided by an embodiment of the present application, the method being executed by a terminal, such as Figure 3 As shown, the following steps are included:

[0053] Step 301, the terminal receives a command sent by a network device;

[0054] Step 302, the terminal performs a target operation according to the command;

[0055] The target operation includes at least one of the following:

[0056] Sending a measurement report when at least two first conditions are met;

[0057] In the case where a mobility process occurs, the mobility process is delayed or a first signaling message is retransmitted, where the first signaling message is a signaling message within a preset time period before the mobility process occurs.

[0058] In an embodiment of the present application, the above command may be a configuration command, or a switching command or a redirection command. For example, if it is a configuration command, in some embodiments, the configuration command may be a command for configuring the terminal to perform measurement reporting. In this case, the command is used to configure the measurement reporting configuration of the terminal, and may carry a condition for triggering the terminal to perform measurement reporting, which is the above first condition. Specifically, the network device may configure multiple first conditions, for example, the measurement reporting conditions configured by the network device may include the following multiple conditions:

[0059] Measuring event A; for example, measuring frequency point A;

[0060] Measuring event B; for example, measuring frequency point B;

[0061] Complete the transmission of data in the uplink buffer or complete the transmission of high-level signaling.

[0062] At present, when one of the measurement reporting conditions is met, the corresponding measurement reporting is directly performed. Since the two first conditions are set to be met, the reporting can be delayed, thereby effectively delaying the execution of the subsequent mobility process. In this way, when the terminal executes the mobility process, it can effectively avoid the incomplete transmission of data in the uplink buffer or the incomplete transmission of high-level signaling, which leads to the loss of data or signaling and affects the reliability of system transmission.

[0063] It should be understood that the above-mentioned multiple first conditions can be configured through one configuration command or through multiple configuration commands, and no further limitation is made here. Further, in order to improve the reliability of signaling transmission, in some embodiments, one of the at least two first conditions includes completing the transmission of data in the uplink cache or completing the transmission of high-level signaling. For example, when measurement event A is met, frequency point A will be measured to obtain a corresponding measurement report. If at this time, if there is data in the uplink cache that has not been transmitted, or high-level signaling has not been transmitted, the above-mentioned measurement report is sent after delaying and waiting for the completion of the transmission of data in the uplink cache or the completion of the transmission of high-level signaling.

[0064] It should be noted that the above conditions for completing the transmission of the data in the uplink buffer or completing the transmission of the high-layer signaling may be agreed upon by the protocol or configured by the network device.

[0065] In some embodiments, the configuration command may be a command for configuring the terminal to delay the execution of a mobility process, in which case the network device may directly configure which mobility processes may be delayed, or configure all mobility processes to be delayed. If the currently executed mobility process is a delayable mobility process, the execution of the mobility process is delayed.

[0066] It should be understood that the above-mentioned high-level signaling can be a non-access stratum (NAS) signaling or an IMS signaling. Taking the completion of the transmission of IMS signaling as an example, in the establishment of the IMS voice signaling bearer, after the UE's measurement event is triggered, the UE sends the measurement report after the high-level signaling IMS is sent. For example, after the measurement event is triggered, the UE high-level IMS is sending an IMS message such as 200OK, then the UE RRC waits for the high-level indication before sending the measurement report. The high-level indication is used for the high-level indication RRC that its IMS signaling is sent, such as sending 200OK. The above-mentioned completion of the transmission of high-level signaling can be understood as sending all high-level signaling, or sending all high-level signaling, and all high-level signaling receives corresponding replies, for example, after sending a Tracking Area Update Request (TAURequest), a Tracking Area Update Accept (TAU Accept) message is received.

[0067] In the embodiment of the present application, the above-mentioned completion of transmission of data in the uplink buffer can be understood as completing the transmission of all data in the buffer, thereby avoiding the data in the buffer not being sent due to the mobility process and being cleared or discarded.

[0068] Optionally, in some embodiments, the target operation includes sending a measurement report when the first condition is met. Since the measurement report is sent when the transmission of data in the uplink cache is completed or the transmission of high-level signaling is completed, the terminal can effectively avoid the incomplete transmission of data in the uplink cache or the incomplete transmission of high-level signaling during the mobility process, which leads to data or signaling loss and affects the reliability of system transmission.

[0069] Optionally, in some embodiments, the target operation includes delaying the execution of the mobility process or retransmitting the first signaling message when the mobility process occurs. Due to the retransmission of the first signaling message, the data or signaling interrupted by the mobility process can be restored. The mobility process is delayed to ensure that the data transmission of the current cache is completed, or the high-level signaling transmission is completed. In this way, when the terminal executes the mobility process, it can effectively avoid the incomplete transmission of the data in the uplink cache or the incomplete transmission of the high-level signaling, resulting in the loss of data or signaling, which affects the reliability of system transmission.

[0070] In the embodiment of the present application, a terminal receives a command sent by a network device; the terminal performs a target operation according to the command; wherein the target operation includes at least one of the following: sending a measurement report when a first condition is met, the first condition including completing the transmission of data in the uplink cache or completing the transmission of high-level signaling; in the event of a mobility process, delaying the execution of the mobility process or retransmitting a first signaling message, the first signaling message being a signaling message within a preset time period before the mobility process occurs. In this way, when executing the mobility process, the terminal can effectively avoid the incomplete transmission of data in the uplink cache or the incomplete transmission of high-level signaling, resulting in the loss of data or signaling, and affecting the reliability of system transmission. Therefore, the embodiment of the present application solves the problem of the terminal executing the mobility process, resulting in the interruption of the transmission of some data or signaling.

[0071] Optionally, in some embodiments, when a mobility process occurs, resending the first signaling message includes:

[0072] In the case where a mobility process occurs, the bottom layer of the terminal sends first indication information to the upper layer of the terminal;

[0073] The higher layer resends the first signaling message according to the first indication information.

[0074] In the embodiment of the present application, the above-mentioned high layer can be understood as the NAS layer and the layers above the NAS layer, and the above-mentioned bottom layer can be understood as the physical layer or the access layer.

[0075] Optionally, the first indication information may be used to indicate any of the following: the occurrence of a mobility process and the occurrence of a voice fallback. For example, after a mobility event occurs in the radio resource control (RRC) of the terminal, the RRC may indicate the mobility event to the upper layer, or, in the case of a voice fallback (voice fallback) occurring in the RRC, the RRC may send a voice fallback indication (voice fallback indication) to the upper layer, and after the upper layer receives the indication from the lower layer, it may resend the first signaling message within N seconds before the mobility process.

[0076] It should be understood that resending the first signaling message can be understood as resending the data or signaling in the buff. If the data or signaling in the buff is not sent out during the switching or redirection process, it will be directly discarded and will not be resent. Only when the preset resending conditions are met, a new signaling message will be regenerated, stored in the buff, and then resent. For example, the calling terminal sends a tracking area update request message, but does not receive a tracking area update acceptance message sent by the called terminal within a preset time period. At this time, the calling terminal will resend the tracking area update request message.

[0077] Optionally, in some embodiments, the content of the first signaling message retransmitted by the high layer may be the same as or different from the content of the first signaling message newly transmitted previously, for example, the first signaling message retransmitted by the high layer is a signaling with updated content. For example, when the first signaling message carries a timestamp, the retransmitted first signaling message will update the timestamp, or when the first signaling message carries state information, the state information carried in the retransmitted first signaling message is the latest state.

[0078] In the embodiment of the present application, the first signaling message may specifically include at least one of the following: a signaling message being sent by a higher layer, a signaling message that has not been successfully sent, and a signaling message to which no response has been received.

[0079] The type of the first signaling message may be a NAS message or an IMS message, etc. The signaling message being sent by the higher layer may be understood as a signaling message that is currently to be sent by the higher layer and has not been sent. The signaling message that has not been successfully sent may be understood as a signaling message that has been sent for confirmation mode signaling, but has not received a reception confirmation from the recipient. The signaling message that has not received a response may be understood as a signaling message that has not received a response message from the recipient to the signaling message after the signaling message is sent, for example, a tracking area update request message is sent, but a tracking area update acceptance message is not received.

[0080] Optionally, in some embodiments, when the target message is sent within the preset time period and no response message corresponding to the target message is received, the first signaling message includes the target message, and the target message is a tracking area update request message or an Internet Protocol Multimedia Subsystem IMS message.

[0081] Taking NAS message as an example, assuming that the above-mentioned target message is a tracking area update message, when a tracking area update request message is sent within the preset time period and no tracking area update acceptance message is received, the first signaling message includes the tracking area update request message.

[0082] In the embodiment of the present application, after retransmitting the tracking area update request message, the tracking area update request message can be retransmitted without increasing the count value of the corresponding counter, and the corresponding timer can be restarted to avoid triggering the wrong counting operation of the counter and avoid the timing error of the timer causing the wrong judgment. In other words, in the embodiment of the present application, in the case of a mobility process, after retransmitting the first signaling message, the method further includes at least one of the following:

[0083] The terminal controls the tracking area update attempt counter not to count the retransmitted tracking area update request message;

[0084] The terminal restarts a timer associated with the tracking area update request message.

[0085] It should be understood that the above timer may be a T3340 timer.

[0086] Optionally, in some embodiments, assuming that the first signaling message includes an IMS message, and the terminal is a calling terminal, the target operation further includes:

[0087] When the content of the currently received first IMS message is the same as the content of the second IMS message, ignoring the second IMS message;

[0088] In a case where the content of the first IMS message is different from the content of the second IMS message, processing the second IMS message;

[0089] The receiving time of the second IMS message is later than the receiving time of the first IMS message.

[0090] In the embodiment of the present application, the content of the first IMS message is the same as the content of the second IMS message, which can be understood as the content indicated by the first IMS message is the same as the content indicated by the second IMS message. For example, the status information of the called terminal is queried through an update message, and the called terminal performs a mobility process within 1 second after the called terminal sends the first IMS message. At this time, the called terminal resends the first IMS message (that is, the second IMS message) after completing the mobile switching process or satisfying the preset precondition. At this time, the first IMS message and the second IMS message are response messages corresponding to the update message, for example, both are 200OK responses. If the first IMS message and the second IMS message both indicate the same terminal status, the second IMS message can be ignored. If they are different, the second IMS message is processed.

[0091] Optionally, in some embodiments, the target operation includes delaying execution of the mobility process when a mobility process occurs, and the command carries second indication information, where the second indication information is used to instruct the terminal to execute the mobility process.

[0092] In an embodiment of the present application, the above-mentioned mobility process may include a switching process or a redirection process, and the above-mentioned command carrying the second indication information can be understood as the above-mentioned command being a command for instructing the terminal to perform the mobility process, that is, the above-mentioned command may be a switching command or a redirection command.

[0093] Delaying the execution of the mobility process by the terminal may include multiple situations. In some embodiments, the network setting may directly instruct the terminal to execute the mobility process, and the terminal determines whether to delay the execution of the mobility process according to its own state, for example, whether to delay the execution of the mobility process according to whether there is a high-level signaling process at present. That is, in the embodiment of the present application, the terminal delays the execution of the mobility process including:

[0094] If the terminal is performing a higher layer signaling process, the terminal performs the mobility process indicated by the second indication information after the higher layer signaling process.

[0095] The above-mentioned high-level signaling process can also be understood as a high-level signaling dialogue, for example, the UE receives a handover or redirection command. When a high-level signaling dialogue or process is in progress, the UE performs a handover or redirection process after the high-level signaling process or dialogue ends.

[0096] The high-level signaling dialogue or process includes a request and a response, such as a tracking area update process in which the UE sends a tracking area update request message and receives a tracking area update accept message.

[0097] For example, in some embodiments, the UE initiates a TAU. At this time, if a handover or redirection command is received, the UE performs the handover or redirection after the TAU ends, and the TAU ends, indicating that the UE receives a TAU Accept. Optionally, the network device indicates to the UE whether the above handover or redirection can be delayed, or indicates that the handover is a delayable handover or the redirection is a delayable redirection.

[0098] In some embodiments, the mobility process indicated by the network device may be defined as a target mobility process that can be delayed. In other words, the mobility process indicated by the second indication information is a target mobility process that can be delayed, and the terminal delays executing the mobility process including:

[0099] When a second condition is met, the terminal performs the mobility process, and the second condition is used to determine a time for delaying the execution of the mobility process.

[0100] In an embodiment of the present application, the second condition can be understood as a delay condition, which may specifically include one or more conditions. For example, in some embodiments, the second condition includes at least one of the following: completion of transmission of high-level signaling and a maximum delay preset duration.

[0101] It should be understood that when the second condition includes the completion of the transmission of high-level signaling, it can be understood that the time indicating the delayed execution of the mobility process is after the time point when the high-level signaling transmission is completed. For example, after the high-level signaling transmission is completed, the mobility process can be executed immediately, and the time point when the high-level signaling is completed can be understood as a dynamic time point.

[0102] In the embodiment of the present application, the network device may directly indicate that the currently indicated mobility process is a delayable mobility process, or the target mobility process may be configured by the protocol agreement or the network device. When the mobility process indicated by the network device belongs to the target mobility process, it can be understood that the mobility process indicated by the network device is a delayable mobility process. In other words, in the embodiment of the present application, the second indication information may be used to indicate that the mobility process may be delayed, or the target mobility process may be configured by the protocol agreement or the network device.

[0103] It should be noted that the above mobility process may be a mobility process occurring based on Evolved Packet System fallback, or a mobility process occurring in other situations, for example, a mobility process occurring based on network quality.

[0104] In order to better understand the present application, the deferrable mobility process is described below through some embodiments.

[0105] In some embodiments, the network device may indicate that the handover is a deferrable handover. The terminal performs the handover after one or more delay conditions are met.

[0106] The delay condition may be configured by the network device or predetermined by a protocol, and the delay condition may specifically include at least one of the following:

[0107] After transmitting the data or high-level signaling in the uplink buffer;

[0108] The maximum delay is X seconds, where X is a positive integer.

[0109] For example, in some embodiments, the network device instructs the UE that it can continue to transmit the data or high-level signaling in the uplink buffer before performing the switch, or instructs the UE that it can start the switch no later than X seconds after receiving the switch command; or instructs the UE that it can switch after sending the data or one of the conditions is met within X seconds.

[0110] Optionally, in some embodiments, when the network device performs lossy switching, such as EPS fallback, the switching process 1 is as follows:

[0111] The network device sends a switching command to the terminal, where the switching command is used to indicate to the UE that the switching is a delayable switching, or the switching command is used to indicate that the switching is an EPS fallback switching, and the protocol predetermines that the EPS fallback switching can be delayed, or the switching command is used to indicate to the UE that the switching allows the UE to continue to transmit the data or high-layer signaling in the uplink buffer before executing the switching.

[0112] After the UE receives the handover command sent by the network device and sends the data in the uplink data buffer or the high-layer signaling, the UE performs the handover.

[0113] Optionally, after receiving the switching command sent by the network device, the UE may suspend the UE uplink and downlink services and then load data into the UE's PDCP or layer 2 buffer; or the RRC may instruct the higher layer to switch and suspend sending new signaling.

[0114] Optionally, in some embodiments, when the network device performs lossy switching, such as EPS fallback, the switching process 2 is as follows:

[0115] The network device instructs the UE to perform the handover after receiving the handover command for X seconds (eg, 1 second). Optionally, the network configures a conditional handover command, and if the measurement results continue to meet the handover condition for a specified time, the handover is performed.

[0116] After receiving the handover command, the UE continues to perform uplink data transmission for 1 second, and performs handover after 1 second.

[0117] In some embodiments, the network device may indicate that the redirection is a delayable redirection. The terminal performs the redirection after one or more delay conditions are met.

[0118] The delay condition may be configured by the network device or predetermined by a protocol, and the delay condition may specifically include at least one of the following:

[0119] After transmitting the data or high-level signaling in the uplink buffer;

[0120] The maximum delay is X seconds, where X is a positive integer.

[0121] For example, in some embodiments, the network device instructs the UE that it can continue to transmit the data or high-level signaling in the uplink buffer before performing redirection, or instructs the UE that it can start performing redirection no later than X seconds after receiving the redirection command; or instructs the UE that it can perform redirection after sending the data or when a condition is met within X seconds.

[0122] Optionally, in some embodiments, redirection may be performed after uplink data transmission is completed, which specifically includes the following process:

[0123] When the network device uses redirection / RRC release to perform EPS fallback, the network device indicates to the UE that the redirection / RRC release is EPS fallback redirection, and instructs the UE that the redirection / RRC release allows the UE to continue to transmit the data in the uplink buffer before executing the redirection / RRC release. At this time, after the UE completes the transmission of the data in the uplink data buffer, the UE executes the redirection / RRC release.

[0124] Optionally, after receiving the redirection / RRC release command, the UE can suspend the UE uplink and downlink services and then load data into the UE PDCP or layer 2 buffer. Alternatively, the RRC indicates that a handover occurs at a higher layer and suspends the sending of new signaling.

[0125] Optionally, in some embodiments, the redirection may be released X seconds after the release command is received. For example, assume that the network device instructs the UE to execute the redirection / RRC release after 1 second of receiving the redirection / RRC release command. Then, the UE continues to execute uplink data transmission for 1 second after receiving the redirection / RRC release command. Then, the redirection / RRC release is executed.
