[0256] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0257] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0258] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the technology described can be used for the systems and radio technologies mentioned above, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and the NR terminology is used in most of the following description, but these technologies can also be applied to applications other than NR system applications, such as 6th generation (6G) systems. th Generation, 6G) communication system.

[0259] A burst can contain one or more data packets, such as a Protocol Data Unit Set (PDU Set), transmitted continuously. Bursts can be separated by a periodic interval. Acknowledging the end of a burst (END) helps the Radio Access Network (RAN) confirm that all data in the burst has arrived, allowing the terminal to enter sleep mode and wait for the next data burst to arrive after the periodic interval.

[0260] In order to determine the end of the periodic burst, the following problems must be solved:

[0261] Question 1: It is not clear how to obtain the burst END information from the transport protocol such as the Real Time Protocol (RTP) / Secure Real Time Protocol (SRTP) header. Currently, RTP is transmitted in units of NAL Units, commonly known as media units. For each NAL Unit, in the RTP extended protocol header, each data unit includes one or more data packets. The first data packet of the data unit can carry a "START" mark. The last data packet of the NAL Unit will carry "END", which is an end indication. Then, by receiving a data packet carrying "END", it can be determined that the NAL Unit has ended. For burst, there are three situations:

[0262] Case 1: Only one data unit is transmitted in the burst. The PDU carrying "END" can be regarded as the burst end PDU, as shown in Figure 2A.

[0263] Case 2: Multiple data units are transmitted in a burst, and the number of data units transmitted in each burst is stable, for example, 2. In this case, the PDU carrying "END" in the second data unit can be regarded as the burst end PDU, as shown in Figure 2B.

[0264] Case 3: Multiple data units are transmitted in a burst, and the number of data units transmitted in each burst is unstable, for example, sometimes 5, sometimes 1, and sometimes 7, with no regular pattern. In this case, carrying the "END" PDU is of no use in determining the end of the burst, as shown in Figure 2C.

[0265] Optionally, the solution to situation 1 is: AF informs the 5G system burst (5G System burst, 5GS burst) of the packet transmission rules, such as whether the RTP extension protocol header is supported, whether only one NAL Unit is stably transmitted in the burst, etc., so that the UPF can treat the PDU carrying "END" as the burst END PDU.

[0266] Optionally, the solution to situation 2 is: AF informs 5GS of the packet transmission rules in the burst, such as whether the RTP extension protocol header is supported, whether only N NAL units are stably transmitted in the burst, etc., so that UPF can treat the PDU carrying "END" in the Nth NAL Unit as the burst END PDU.

[0267] Optionally, the solution to situation 3 can be as follows:

[0268] One solution: After receiving each NAL Unit, the UPF waits for a first time period. When the first time period expires, it is considered a burst end. However, by this time, all previously received NAL Units have already been sent to the RAN. The UPF needs to create a fake data packet, such as a dummy PDU, and send it to the RAN with a burst end.

[0269] Solution 2: RAN can wait for confirmation. For example, if the inactive timer is greater than the first time period, RAN will stop waiting and go into sleep mode.

[0270] Sub-question 1: How to determine the first time period.

[0271] Solution: 5GS statistics or AF provides a jitter range, which measures the delay between two NAL units or PDUs. For example, if burst packets arrive approximately 20 microseconds apart, any arrival time interval exceeding 20ms is considered jitter. For example, if the jitter range is +-2ms, the first time period can be set to 2ms or slightly greater. Since PDUs outside the jitter range are rare, it's advisable not to wait for these rare delayed packets.

[0272] In addition, the first time period should be less than the burst period minus a second time period, where the second time period is the time period between the arrival time of the last packet in the burst and the start time of the burst.

[0273] Sub-problem 2: Since energy saving is mainly achieved by UE sleep, the UE can only enter the sleep state when both the uplink burst and the downlink burst have ended. Currently, the base station does not know when the uplink burst has ended.

[0274] Solution 1: In the uplink direction, the UE can notify the base station whether the data transmission in the burst has ended.

[0275] Solution 2: RAN can wait for confirmation. For example, if the inactive timer is greater than the first time period, RAN will stop waiting and enter sleep mode.

[0276] Question 3: In related technologies, the SMF independently determines whether to detect the end of a burst packet and mark the end of the burst indication. It is unclear whether third-party applications or the PCF can request or require such operations. Furthermore, some RTP protocols support providing a burst end indication, but others do not. If the RTP protocol does not support a burst end indication, the end of the burst packet cannot be determined. In this case, instructing the PSA UPF to detect and mark the end of the burst packet is meaningless and wastes resources. How the network distinguishes between these scenarios and determines whether to require the end of data transmission to be marked remains to be determined.

[0367] The first data packet is an end data packet of the first data unit, and the first data packet carries a first end indication;

[0368] The first data unit satisfies at least one of the following: a data unit in the first burst, mapped to a data unit of the first data packet set;

[0369] The first jitter range is the jitter range of the time interval between the data packets.

[0370] In one embodiment, when the first communication device is a core network element (e.g., a UPF), the data packet (e.g., the first data packet, the forged data packet) is a downlink data packet. The sending of the forged data packet includes one of the following: sending the forged data packet to a RAN network element, or sending the forged data packet to an N3 or N9 interface.

[0371] In one embodiment, when the first communication device is a terminal, the data packet (eg, the first data packet, the forged data packet) is an uplink data packet, and sending the forged data packet includes sending the forged data packet to a RAN.

[0372] In one embodiment, when the first communication device is a RAN network element, the data packet (e.g., the first data packet, the forged data packet) includes an uplink and / or downlink data packet. Sending the forged data packet includes one of the following: sending the forged data packet to the RAN network element, or sending the forged data packet to an N3 or N9 interface.

[0373] In one embodiment, in a first sub-operation of the first operation, the first communication device determines that the first burst ends by receiving a first data packet.

[0374] In one embodiment, the first communication device receives the first information and / or the second information from a source end, and the source end includes a third communication device.

[0375] In one embodiment, there are intervals between bursts, and bursts may or may not have periodic characteristics. Each burst contains one or more data units, and the first burst represents a burst. Each burst has a data transmission start and data transmission end.

[0376] The burst end refers to the end of data transmission in the burst.

[0377] The burst end indication is used to indicate one of the following: data transmission in the burst is completed, and the data packet carrying the burst end indication is the last data packet of the burst.

[0378] The data packet set end indication is used to indicate one of the following: data in the data packet set has been transmitted, and the data packet carrying the data packet set end indication is the last data packet in the data packet set.

[0379] The data unit end indication is used to indicate one of the following: data in the data unit has been transmitted, and the data packet carrying the data unit end indication is the last data packet of the data unit.

[0380] In one implementation, the end data packet of a burst refers to a data packet that is not followed by other data packets of the burst.

[0381] In one implementation, the first duration is configured on the first communication device, or the first duration is received.

[0382] In one implementation, the first communication device configures the second duration, or receives the second duration.

[0383] In one embodiment, in the first operation, causing the data packet (such as the first data packet) to carry the second end indication includes: setting the second end indication in the first header of the data packet. In one embodiment, the first header is, for example, a GTP-U header.

[0384] The time interval between packets in a burst is the transmission or arrival time interval between two consecutive packets in a burst.

[0385] The average duration of the time interval between packets in a burst. For example, if the time interval between the first and second packets is 10 microseconds, the time interval between the second and third packets is 15 microseconds, and the time interval between the third and fourth packets is 20 microseconds, then the average time interval is 15 microseconds, and the maximum time interval is 20 microseconds.

[0386] In one embodiment, restarting the mth timer includes restoring the mth timer's timing duration to a maximum value or an initial state. For example, if the mth timer has a maximum timing duration of 20 microseconds and a data packet is received after 10 microseconds have elapsed, the counter is restored to its initial state and starts counting again. Specifically, if the mth timer counts up, the counter returns to a zero-second state, and if the mth timer counts down, the counter returns to a 20-microsecond state. m can be one of the following values: 1, 2, 3, or 4.

[0387] In one implementation, the first duration is the same as or different from the second duration.

[0388] In one embodiment, the first timer and the second timer are the same or different.

[0389] In one embodiment, when all data in a burst is mapped to a data packet set, the end of the burst also marks the end of the data packet set. For example, if a burst contains N data units, and these N data units are mapped to a data packet set, the last data packet of the Nth data unit is the ending data packet of the burst or the data packet set. In this scenario, the end of the burst is equivalent to the end of the data packet set. The first, second, and third sub-operations described above can be used to determine the end of a burst or a data packet set in this scenario.

[0390] In another embodiment, when data units are mapped one-to-one to data packet sets, the end of a data unit also marks the end of the data packet set. For example, if a burst contains N data units, then these N data units map to N data packet sets. In this scenario, the end of a burst is not equivalent to the end of a data packet set. The fourth and fifth sub-operations described above can be used to determine the end of a data packet set in this scenario.

[0391] Optionally, determining the end data packet of the first burst or the first data packet set includes at least one of the following:

[0392] If the first communication device still has received data packets of the first burst, the first communication device uses the last received data packet in the first burst as the end data packet of the first burst or the first data packet set;

[0393] If the first communication device does not have a data packet of the first burst, the first communication device creates a forged data packet and uses the forged data packet as the end data packet of the first burst or the first data packet set;

[0394] And / or, the first duration is used for one of the following: determining the end of a burst, determining the end of a data unit, and determining the end of a data packet set; or, the first duration is used to indicate the maximum duration of timing by a first timer;

[0395] And / or, the first timer is a timer used for one of the following: determining the end of burst data transmission, determining the end of data unit transmission, and determining the end of data packet set transmission;

[0396] And / or, the second duration is used for one of the following: determining the end of a data unit, determining the end of a data packet set; or, the second duration is used to indicate the maximum duration of the second timer;

[0397] And / or, the second timer is a timer used to determine the end of data unit transmission or the end of data packet set transmission.

[0398] Optionally, the first jitter range includes at least one of the following:

[0399] The maximum value of the positive jitter of the time interval between packets;

[0400] Minimum of the negative jitter values ​​of the time interval between packets.

[0401] In one implementation, the first jitter range is [+5, -5], the maximum positive jitter value is +5, and the minimum negative jitter value is -5.

[0402] For example, if the average duration of a time interval is 15 microseconds, based on the first jitter range and the average duration of the time interval, the maximum duration of the time interval can be determined to be 20 microseconds. It is not difficult to understand that when the first communication device receives the Mth packet in a burst, if it does not receive the M+1th packet within 20 microseconds, the burst is likely to have ended. In other words, the Mth packet can be determined to be the end packet of the burst.

[0403] Optionally, the first end indication is one of the following:

[0404] End indication in the first protocol header;

[0405] End of data unit indication;

[0406] The end of the burst indication;

[0408] In one implementation, the end indication in the first protocol header includes: an end indication of a burst in the first protocol header.

[0409] In one implementation, the protocol description information may be used for at least one of the following:

[0410] Describes the protocol or protocol header used by the business data flow;

[0411] Describes the protocol or protocol header used to detect the end of the burst packet;

[0412] The information indicating that the first protocol or the first protocol header supports providing at least one of the following: a first end indication, information for identifying an end packet of a burst, and information for adding a second end indication to a packet.

[0413] In one embodiment, the terminal's IP data packet is transmitted in a GTP-U pipeline, and the terminal's data packet has a GTP-U header in addition to the IP header. The first protocol is the IP header of the terminal's data packet or other protocol headers within the IP header.

[0414] In one embodiment, the first protocol includes one of the following: an IP layer protocol or a protocol above the IP layer of the terminal data packet, an RTP protocol, or an SRTP protocol; and / or the first protocol does not include a user-layer GPRS tunnel protocol GTP-U.

[0415] Optionally, the performing of the first sub-operation of the first operation includes:

[0416] The first communication device performs a first sub-operation of the first operation when a first condition is met;

[0417] The first condition includes at least one of the following:

For example, for a burst end, the packet filter is the end indication in the first protocol header (e.g., the END bit is set to 1). Therefore, any data packet that carries the end indication in the first protocol header (e.g., the END bit is set to 1) can be considered a burst end packet or a data unit end packet.

[0562] In one embodiment, restarting the third timer includes restoring the timing duration of the third timer to a maximum value or an initial state. For example, if the maximum timing duration of the third timer is 20 microseconds, and a data packet is received after 10 microseconds have elapsed, the counter is restored to its initial state and starts counting again. That is, counting up means returning to a zero-second state, and counting down means returning to a 20-microsecond state.

[0563] In one embodiment, restarting the fourth timer includes restoring the fourth timer's timing duration to a maximum value or an initial state. For example, if the fourth timer has a maximum timing duration of 20 microseconds and a data packet is received after 10 microseconds have elapsed, the counter is restored to its initial state and starts counting again. That is, counting up means returning to a zero-second state, and counting down means returning to a 20-microsecond state.

[0569] The fourth timer is a timer used to determine the end of data transmission of a data packet set.

[0570] Optionally, the first sub-operation of performing the second operation includes:

[0574] The number of data packet sets transmitted in each burst is the same, only one data packet set is transmitted in each burst, or M data packet sets are transmitted in each burst;

[0576] Optionally, the second sub-operation of performing the second operation includes:

[0577] When a seventh condition is met, the second communication device performs a second sub-operation of the second operation;

[0578] The seventh condition includes at least one of the following:

[0579] The second burst begins;

[0580] The first packet in the second burst is received;

[0581] A data packet is received before the third timer or the third duration times out;

[0582] A data packet is received before the third timer or the third duration expires, and the data packet satisfies at least one of the following conditions: it is not the last data packet of the second burst, does not carry the second end indication, and is a data packet in the Mth data packet set;

[0583] The duration of the second burst ends before the third timer or the third duration expires;

[0584] Before the third timer or the third duration times out, the next burst starts;

[0585] The second end indication includes one of the following: a burst end indication, a data packet set end indication.

[0586] In one embodiment, when all data in a burst is mapped to a single data packet set, the end of the burst also corresponds to the end of the data packet set. For example, if a burst contains N data units, and these N data units are mapped to a data packet set, the last data packet of the Nth data unit is the ending data packet of the burst or the data packet set. In this scenario, the end of the burst is equivalent to the end of the data packet set. The third sub-operation described above can be used to determine the end of the burst in this scenario.

[0587] In another embodiment, when data units are mapped one-to-one to data packet sets, the end of the data unit also corresponds to the end of the data packet set. For example, if there are N data units in a burst, then N data units are mapped to N data packet sets. In this scenario, the end of the burst is not the same as the end of the data packet set.

[0588] In one embodiment, the second burst is a burst in the data stream. The start of the second burst represents the start of data transmission in the second burst. The second communications device can determine the start of a burst based on at least one of the following: receiving the first data packet of the burst and inferring the burst start time based on the burst period. For example, if the burst is the Mth burst in the data stream and the burst period is Y, the burst start time can be inferred using M×Y.

[0589] When the burst has a periodic characteristic, the duration of the burst is the burst period.

[0590] In one embodiment, when the seventh condition is met, the second communication device starts a third timer or waits for a third period of time.

[0591] The second end indication is the second end indication in the first packet header (such as a GTP-U packet header).

[0592] Optionally, the third sub-operation of executing the second operation includes:

[0593] When an eighth condition is met, the second communication device performs a third sub-operation of the second operation;

[0594] The eighth condition includes at least one of the following:

[0595] The third timer times out or the third waiting period times out;

[0596] Before the third timer or the third duration times out, the last data packet of the second burst or the tenth data packet set is received.

[0597] In one embodiment, the second communication device stops the third timer from timing, or stops waiting for the third time period when the eighth condition is met.

[0598] In one implementation, the last received data packet in the second burst is the data packet that triggers "the last third timer timing or third waiting time in the second burst".

[0599] It is easy to understand that when the second communication device receives the Mth data packet in the second burst, it starts or restarts the third timer or waits for the third period. If the third timer times out or the third waiting period times out without receiving the M+1th data packet, the second burst can be considered to have ended. That is, the Mth packet can be determined to be the end packet of the second burst.

[0600] Optionally, the last data packet of the second burst is one of the following: the end data packet of the Mth data packet set in the burst; the data packet carrying the second end indication in the Mth data packet set in the burst; wherein M is an integer greater than or equal to 1.

[0601] In one embodiment, the second communication device learns that data of M data packet sets will be transmitted in the second burst, and the Mth data packet set is the last data packet set of the second burst. The end data packet of the Mth data packet set is the end data packet of the burst.

[0602] In one implementation, the end data packet of the Mth data packet set may be a data packet in the Mth data packet set that carries an indication of the end of the data packet set.

[0603] In another implementation, the end data packet of the Mth data packet set may be the end data packet of the data packet set determined by the fifth sub-operation.

[0604] Optionally, the seventh condition or the eighth condition further includes at least one of the following:

[0605] The number of data packet sets transmitted in each burst is the same, only one data packet set is transmitted in each burst, or M data packet sets are transmitted in each burst;

[0606] The tenth data packet set also satisfies: being the Mth data packet set or the last data packet set in the burst.

[0607] Optionally, the fourth sub-operation of executing the second operation includes:

[0608] When a ninth condition is met, the second communication device performs a fourth sub-operation of the second operation;

[0614] The duration of the second data packet set ends before the fourth timer or the fourth duration times out;

[0615] Before the fourth timer or the fourth duration times out, the next data packet set starts.

[0616] Optionally, when the transmission between data packet sets (such as a burst only transmits one data packet set, then the burst period can also be considered as the transmission period of the data packet set) has a periodic characteristic, the duration of the data packet set is the transmission period of the data packet set.

[0617] In one embodiment, the second data packet set is a data packet set in a data stream. The start of the second data packet set represents the start of data transmission for the second data packet set. The second communications device can determine the start of a data packet set based on at least one of the following: receiving the first data packet of the data packet set and inferring the start time of the data packet set based on the period of the data packet set. For example, if the data packet set is the Mth data packet set in the data stream and the data packet set period is Y, then the start time of the data packet set can be inferred based on M×Y.

[0618] Optionally, when the data packet set has a periodic characteristic, the duration of the data packet set is the data packet set period.

[0627] In one embodiment, the last received data packet in the second data packet set is the data packet that triggers “the last fourth timer timing or fourth waiting time in the second data packet set”.

[0628] It is easy to understand that when the second communication device receives the Mth data packet in the second data packet set, it starts or restarts the fourth timer or the fourth waiting period. If the fourth timer times out or the fourth waiting period times out without receiving the M+1th data packet, the second data packet set can be considered to have ended. In other words, the Mth packet can be determined as the end packet of the second data packet set.
