In order to better understand the technical solutions provided by the embodiments of the present application, the following explains related concepts possibly related to the embodiments of the present application.

Packet data convergence protocol (Packet Data Convergence Protocol, PDCP) functional profile

Referring to fig. 2, fig. 2 is a schematic diagram of an NR User Plane (UP) protocol architecture, where the NR UP protocol architecture is composed of a service data adaptation protocol (Service Data Adaptation Protocol, SDAP), PDCP, radio link control (Radio Link Control, RLC), medium access control (Medium Access Control, MAC), and Physical layer (PHY) according to an embodiment of the present application. The PDCP packets received from the upper SDAP are PDCP service data units (Service Data Unit, SDU), and the PDCP protocol data units (Protocol Data Unit, PDU) are PDCP packets processed by and associated with the PDCP layer encapsulation header. The PDCP layer needs to process (e.g., security process, associate PDCP header (header), etc.) each received PDCP SDU to generate PDCP PDUs. NR also introduces a preprocessing function, so PDCP PDUs processed and generated for PDCP can be directly delivered to RLC.

The method for processing the data packet concatenation provided by the embodiment of the application is described in detail below by means of some embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 3, fig. 3 is a flowchart of a processing method of packet concatenation according to an embodiment of the present application, as shown in fig. 3, the method includes the following steps:

step 301, the terminal acquires cascade configuration information.

The concatenation configuration information may be sent by a network side (such as a base station) to a terminal, and is used for indicating to perform concatenation operation on a data packet of a target service.

And 302, the terminal executes cascading operation on the data packet of the target service based on the cascading configuration information.

Illustratively, the terminal may concatenate three data packets of the target service into one concatenated data packet based on the concatenated configuration information, where the concatenated data packet is associated with an encapsulation packet header; alternatively, the terminal may concatenate the four packets of the target service into a concatenated packet based on the concatenated configuration information, where the concatenated packet is associated with an encapsulation packet header, and so on. Alternatively, the network side may indicate the number of sub-packets of the concatenated data packet through the concatenation configuration information, that is, indicate how many data packets the terminal concatenates into one concatenated data packet.

Optionally, the target service is identified by at least one of the following information:

session identification information;

carrying identification information.

The session Identification information may be, for example, a PDU session (Identification) Identification (ID); the Bearer identification information may be, for example, a Radio Bearer (RB) ID.

Optionally, the protocol layer for the terminal to perform the cascading operation includes any one of the following:

a PDCP layer;

SDAP layer.

In an embodiment of the present application, the cascade configuration information includes at least one of the following:

the number information of the cascade data packets;

size information of the concatenated data packet;

time information of concatenated data packets.

The number information of the cascade data packets is used for indicating the number of the data packets which can be executed by the terminal through cascade operation. For example, if the number of packets that the network side configures PDCP to be able to concatenate is 3, that is, the concatenation configuration information indicates that the number of packets that the terminal can perform the concatenation operation is 3, the PDCP layer of the terminal may concatenate three packets of the target service received from an upper layer into one concatenated packet, for example concatenate three packets of PDCP SDU #1, PDCP SDU #2, PDCP SDU #3 into one PDCP SDU.

The size information of the concatenated data packet is used for indicating the packet size of the concatenated data packet for the terminal to execute the concatenation operation. For example, when the network side configures PDCP to be capable of concatenating data packets having a size of 300 bytes, that is, the concatenation configuration information indicates that a packet size of a concatenated data packet formed by the terminal performing a concatenation operation is 300 bytes, the PDCP layer of the terminal may concatenate at least two data packets received from an upper layer into one concatenated data packet having a packet size equal to or less than 300 bytes, for example, the terminal concatenates three data packets of PDCP SDU #1, PDCP SDU #2, PDCP SDU #3 (assuming that each data packet is 100 bytes) into one PDCP SDU.

And the time information of the cascade data packet is used for indicating the terminal to execute cascade operation on the received data packet in the time period characterized by the time information. Illustratively, the network side configures time information of the concatenated data packet as a concatenated timer, and the PDCP layer of the terminal performs a concatenation operation on the data packet received during the operation of the timer to concatenate into a concatenated data packet.

The concatenation configuration information may include at least one of the number information of the concatenation data packets, size information of the concatenation data packets, and time information of the concatenation data packets. For example, the concatenation configuration information includes number information of concatenation data packets and time information of the concatenation data packets, and the terminal may perform concatenation operation on the number of data packets indicated by the number information of concatenation data packets in a period of time represented by the time information of the concatenation data packets. Alternatively, the concatenation configuration information may further include number information of concatenated data packets and size information of the concatenated data packets, and the terminal may perform concatenation operation according to a packet size indicated by the size information of the concatenated data packets and a number of data packets indicated by the number information of the concatenated data packets, for example, the packet size indicated by the size information of the concatenated data packets is 300 bytes, and the number of data packets that can be concatenated indicated by the number information of the concatenated data packets is 3, for example, the terminal concatenates three data packets of PDCP SDU #1, PDCP SDU #2, PDCP SDU #3 (assuming that each data packet is 100 bytes) into one PDCP SDU. Of course, the content of the cascade configuration information may be other possible situations, which is not listed in this embodiment.

Optionally, the terminal performs a concatenation operation on the data packet of the target service based on the concatenation configuration information, including at least one of the following:

in the case that the concatenation configuration information includes the number information of the concatenation data packets, the terminal performs concatenation operation on the data packets of the target service reaching a target number based on the number information of the concatenation data packets, where the target number is the number indicated by the number information of the concatenation data packets;

in the case that the cascade configuration information includes size information of the cascade data packet, the terminal performs a cascade operation on a data packet of a target service smaller than or equal to a target cascade packet size based on the size information of the cascade data packet, the target cascade packet size being a size of the cascade data packet indicated by the size information of the cascade data packet;

and under the condition that the cascade configuration information comprises the time information of the cascade data packet, the terminal executes cascade operation on the received data packet of the target service in a target time period based on the time information of the cascade data packet, wherein the target time period is a time period indicated by the time information of the cascade data packet.

For example, in one embodiment, if the concatenation configuration information includes the number information of the concatenated packet, and assuming that the target number indicated by the number information of the concatenated packet is 5, the terminal may perform the concatenation operation on the packet up to the target number based on the target number indicated by the number information of the concatenated packet. For example, the terminal PDCP layer may concatenate into one concatenated packet every packet of 5 target services.

Alternatively, in another embodiment, if the concatenation configuration information includes size information of the concatenated packet, and assuming that a target concatenation packet size indicated by the size information of the concatenated packet is 300 bytes, the terminal may perform a concatenation operation on a packet less than or equal to 300 bytes based on the target concatenation packet size indicated by the size information of the concatenated packet; illustratively, if the terminal PDCP layer receives 3 packets from an upper layer and the sum of the packet sizes of the 3 packets is 300 bytes, the terminal concatenates the 3 packets into one concatenated packet; alternatively, if the PDCP layer of the terminal receives the packet size sum of 4 packets from the upper layer to be 350 bytes, wherein the packet size sum of the first 3 packets is 280 bytes, the terminal concatenates the first 3 packets into one concatenated packet.

Or in another embodiment, if the concatenation configuration information includes time information of the concatenation data packet, the terminal performs concatenation operation on a data packet of the target service received in a target time period indicated by the time information of the concatenation data packet.

Alternatively, in another embodiment, if the concatenation configuration information includes time information of the concatenated data packet and number information of the concatenated data packet, and assuming that the target number indicated by the number information of the concatenated data packet is 3, the terminal PDCP may concatenate every 3 data packets received from an upper layer into one concatenated data packet within a target period indicated by the time information of the concatenated data packet.

Optionally, the information content of the cascade configuration information may be other possible cases, and the terminal may execute a corresponding cascade operation based on the information content of the cascade configuration information, which is not specifically shown in the embodiment of the present application.

Optionally, the terminal performs concatenation operation on the data packets of the target service reaching the target number based on the number information of the concatenated data packets, including:

the terminal executes cascading operation based on the first counter;

The first counter is used for counting the number of data packets of the target service received from an upper layer.

The first counter may be a counter configured at the network side, an initial value of the first counter is 0, a maximum value of the first counter may be a value of a target number represented by the number information of the concatenated data packet, and when a count value of the first counter reaches the maximum value, the terminal performs a concatenation operation on the received data packet of the target service. In this way, the terminal can perform the concatenation operation on the data packets with the target number through the first counter, so that the concatenation processing on the data packets is better realized.

Optionally, the terminal performs a cascading operation based on the first counter, including:

in case of receiving a data packet of a target service from an upper layer, the terminal updates a count value of the first counter;

and under the condition that the first counter reaches a first target value, the terminal executes cascading operation on the received data packets of the target service, wherein the first target value is the value of the target number.

For example, the number of the cascade packets included in the cascade configuration information is characterized by a target number of 3, that is, a first target value is 3; the method comprises the steps that a first counter is added with 1 from PDCP SDU #1 received by an upper layer, when PDCP SDU #2 is received by the upper layer, the first counter is added with 1 again, when PDCP SDU #3 is received by the upper layer, the first counter is added with 1 again, and the current value is 3. At this time, the PDCP concatenates the three received packets of PDCP SDU #1, PDCP SDU #2, PDCP SDU #3 into one PDCP SDU. Therefore, the terminal can execute cascading operation on the received data packets of the target service through the first counter so as to cascade a plurality of data packets into a cascading data packet, and the cascading data packet only needs to be associated with one packaging packet header, so that the header overhead of the terminal for processing the data packets is effectively saved.

Optionally, the method further comprises any one of the following:

under the condition that the terminal receives a data packet of a target service from an upper layer, if the first counter has reached the first target value, the terminal resets and updates the first counter;

the terminal resets the first counter under the condition that the first counter reaches the first target value;

after the first counter reaches the first target value, in the case that the terminal receives a first data packet of a target service from an upper layer, the terminal enables a new first counter and updates the new first counter.

It should be noted that one first counter may be common to a plurality of concatenated data packets. It will be appreciated that in one case, the count value of the first counter is configured based on the granularity of the radio bearer, and the same first counter is used for each of the plurality of concatenated data packets corresponding to the radio bearer.

Or it may be that a first counter is associated with a concatenated packet. It will be appreciated that in one case, the maximum count value of the first counter is configured based on the granularity of the radio bearer, and a different first counter is used for the plurality of concatenated data packets corresponding to the radio bearer, but the count values of the different first counters may be the same.

For example, in the embodiment of the present application, one first counter is associated with N concatenated data packets, or N first counters are associated with N concatenated data packets one by one, where N is an integer greater than 1.

Wherein, in the case that a first counter is associated with each concatenated packet (it may be understood that a first counter is shared by a plurality of concatenated packets), each time the terminal receives a packet of the target service from an upper layer, the count value of the first counter is incremented by 1, and when the count value of the first counter reaches the first target value, the terminal concatenates the received packets into a concatenated packet. Additionally, the terminal performs a reset operation on the first counter, and resets to an initial value (e.g., 0). Upon subsequent reception of the data packet from the upper layer, the terminal performs an update operation based on the initial value. Illustratively, if the number of packets that the network side configuration terminal PDCP can concatenate is 3, the PDCP performs a reset operation (reset to an initial value) on the current first counter after receiving the 3n (n is a positive integer) th packet from the upper layer. In the 3n+1 (n is a positive integer) th packet, the current value of the first counter is always the initial value, so that the terminal always performs the update operation based on the initial value when the 3n+1 (n is a positive integer) th packet arrives.

Alternatively, in the case where one first counter is associated with each concatenated packet (it will be understood that one first counter is common to a plurality of concatenated packets), when the count value of the first counter has reached the first target value, the terminal concatenates the received packets into one concatenated packet and performs a reset operation on the first counter, resets to an initial value, and starts to recount based on the initial value when the first packet belonging to the next concatenated packet arrives. Illustratively, if the number of packets that the network side configuration terminal PDCP can concatenate is 3, the PDCP performs a reset operation (reset to an initial value) on the current first counter and performs an update based on the initial value when the 3n+1 (n is a positive integer) th packet is received from an upper layer. In the 3n+1 (n is a positive integer) th packet, the count value of the first counter has reached the first target value, so the terminal needs to reset the counter to the initial value and then perform the update operation based on the initial value.

Alternatively, in the case where one first counter is associated with one concatenated packet (it may be understood that one first counter is not shared by a plurality of concatenated packets), when the count value of the first counter reaches the first target value, if the terminal receives the first packet belonging to the next concatenated packet from the upper layer, the terminal enables a new first counter and updates the new first counter, that is, counts the packets of the next concatenated packet. Illustratively, the network side configures the number of packets that the terminal PDCP can concatenate to be 3, and when the terminal receives PDCP SDU #4 from an upper layer, the terminal enables a new first counter and performs an update operation on the first counter.

In the embodiment of the application, the terminal executes the cascade operation on the data packet of the target service through the first counter, so that the data packet can be better processed by means of the first counter.

Optionally, the terminal performs a concatenation operation on a data packet of a target service reaching a target concatenation packet size based on size information of the concatenation data packet, including:

the terminal executes cascading operation based on the second counter;

wherein the second counter is used for counting the total bytes of the data packet of the target service received from the upper layer.

The second counter may be a counter configured on the network side, an initial value of the second counter may be 0, a maximum value of the second counter may be a total byte number, such as M bytes, of a concatenated packet size characterized by size information of the concatenated packet, and when a count value of the second counter is less than or equal to M bytes, the terminal performs a concatenation operation on the received data packet of the target service. In this way, the terminal can perform the concatenation operation on the data packet through the second counter, so as to better realize the concatenation processing on the data packet.

Optionally, the terminal performs a cascading operation based on the second counter, including;

in case of receiving a data packet of a target service from an upper layer, the terminal updates a count value of the second counter;

and under the condition that the count value of the second counter is smaller than or equal to a second target value, the terminal executes cascading operation on the received data packet of the target service, wherein the second target value is the byte number of the target cascading packet size.

For example, the terminal PDCP receives PDCP SDU #1 from the upper layer, the second counter performs an update operation, where the update step size is equal to the packet size M1 of PDCP SDU #1, and the current value of the second counter is M1; when receiving PDCP SDU#2 from an upper layer, the second counter executes updating operation again, and the updating step length is equal to the data packet size M2 of the PDCP SDU#2, and the current value of the second counter is M1+M2; when the PDCP SDU #3 is received from the upper layer, the second counter performs an update operation again, and the update step length is equal to the packet size M3 of the PDCP SDU #3, and the current value of the second counter is m1+m2+m3. If m1+m2+m3=m (M is the second target value), the terminal PDCP concatenates three packets, PDCP sdu#1, PDCP sdu#2, PDCP sdu#3, into one PDCP SDU.

Therefore, the terminal can execute cascading operation on the received data packets of the target service through the second counter so as to cascade a plurality of data packets into a cascading data packet, and the cascading data packet only needs to be associated with one packaging packet header, so that the header overhead of the terminal for processing the data packets is effectively saved.

the terminal maximizes the number M of data packets and performs cascading operation on the M data packets, wherein the total byte number of the M data packets is smaller than the byte number of the target cascading packet.

For example, assuming that the number of bytes of the target concatenation packet size configured by the network side is 300 bytes, if PDCP sdu#1 received by the terminal PDCP from the upper layer is 100 bytes, PDCP sdu#2 is 80 bytes, PDCP sdu#3 is 100 bytes, PDCP sdu#4 is 30 bytes, the number of maximized packets of the terminal is 3, that is, three packets of PDCP sdu#1, PDCP sdu#2, and PDCP sdu#3 are concatenated into one PDCP SDU, and only two packets of PDCP sdu#1 and PDCP sdu#2 cannot be concatenated.

The terminal can cascade the most data packets into one cascade data packet as much as possible under the condition that the size of the target cascade packet configured on the network side is not exceeded by maximizing the number of the data packets, thereby being more beneficial to saving the terminal cost.

In an embodiment of the present application, the method further includes any one of the following:

under the condition that the terminal receives a data packet of a target service from an upper layer, if the second counter is smaller than or equal to the second target value, the terminal resets and updates the second counter;

the terminal resets the second counter if the second counter is less than or equal to the second target value;

after the second counter is less than or equal to the second target value, in case the terminal receives a first packet of a target service from an upper layer, the terminal enables a new second counter and updates the new second counter.

It should be noted that one second counter may be associated with a plurality of concatenated data packets (it may be understood that the second counter is common to a plurality of concatenated data packets), and it may be understood that in one case, the count value of the second counter is configured based on granularity of a radio bearer, and the same second counter is used for each of the plurality of concatenated data packets corresponding to the radio bearer. Or it may be that one second counter is associated with one concatenated packet (it will be understood that the second counter is not common to multiple concatenated packets). It will be appreciated that in one case the count value of the second counter is configured based on the granularity of the radio bearer, a different second counter is used for the plurality of concatenated data packets corresponding to the radio bearer, but the maximum count value of the different second counter may be the same.

For example, one second counter is associated with M concatenated data packets, or M second counters are associated with M concatenated data packets one by one, where M is an integer greater than 1.

For example, in the case where a second counter is associated with each concatenated packet (it will be understood that a second counter is common to a plurality of concatenated packets), each time a terminal receives a packet of a target service from an upper layer, the second counter adds the number of bytes of the packet based on the current count value, and when the count value of the second counter is less than or equal to the second target value, the terminal concatenates the received packets into one concatenated packet and performs a reset operation on the second counter to an initial value (e.g., 0), and when a packet is subsequently received from the upper layer, the terminal performs an update operation based on the initial value.

Illustratively, the second target value configured by the network side is 300 bytes, PDCP is 100 bytes for PDCP SDU #1 received from the upper layer, PDCP SDU #2 is 100 bytes, and PDCP SDU #3 is 100 bytes. The count value of the second counter is updated to 300 upon receipt of PDCP SDU #3, i.e., equal to the second target value 300. The terminal concatenates three data packets of PDCP SDU #1, PDCP SDU #2, PDCP SDU #3 into one PDCP SDU. Additionally, the terminal performs a reset operation on the second counter, i.e., resets to an initial value of 0. When receiving PDCP SDU #4 as 30 bytes, the count value of the second counter is updated from the initial value 0 to 30.

Alternatively, in the case that one second counter is associated with each concatenated packet (it may be understood that one second counter is common to a plurality of concatenated packets), when a packet is received from an upper layer, if the count value of the second counter has reached the second target value, the terminal will perform a reset operation on the second counter to an initial value, and the second counter starts to recount based on the initial value.

For example, the second target value configured by the network side is 300 bytes, PDCP is 100 bytes for PDCP SDU #1 received from the upper layer, PDCP SDU #2 is 80 bytes, PDCP SDU #3 is 100 bytes, the count value of the second counter is 280, which is smaller than the second target value 300, when PDCP SDU #4 is 30 bytes, if the second counter continues counting, it is larger than the second target value, the terminal concatenates three data packets of PDCP SDU #1, PDCP SDU #2, PDCP SDU #3 into one PDCP SDU, resets and updates the second counter, counts the received PDCP SDU #4 based on the updated second counter, and performs counting of the concatenated data packets of the next round. This scenario, i.e. the case where the second counter is smaller than the second target value, will not be described later.

Alternatively, in the case where one second counter is associated with one concatenated packet (it may be understood that one second counter is not shared by a plurality of concatenated packets), when the count value of the second counter reaches the second target value, if the terminal receives the first packet belonging to the next concatenated packet from the upper layer, the terminal enables a new second counter and updates the new second counter, that is, counts the packets of the next concatenated packet. Illustratively, when the terminal has concatenated three data packets of PDCP SDU #1, PDCP SDU #2, PDCP SDU #3 into one PDCP SDU, the terminal enables a new second counter for receiving PDCP SDU #4 from an upper layer and performs an update operation on the second counter.

In the embodiment of the application, the terminal executes the cascade operation on the data packet of the target service through the second counter, so that the data packet can be better processed by means of the second counter.

Optionally, the terminal performs a concatenation operation on the received data packet of the target service in the target time period based on the time information of the concatenated data packet, including:

The terminal executes cascading operation based on the first timer;

the timing length of the first timer is configured based on the time information of the cascade data packet, and the timing length of the first timer is the target time period.

Illustratively, the first timer may be a timer configured by the network side, and the terminal performs a concatenation operation on the data packet of the target service received in the timing length of the first timer. The terminal performs the concatenation operation based on a first timer, which is started when a first sub-packet of the concatenated data packet arrives, and the data packets arrived during the operation of the first timer are all attributed to one concatenated data packet, and the data packets arrived after the first timer times out are attributed to another concatenated data packet, so that the terminal can better realize the concatenation processing of the data packets by means of the timing of the first timer.

Optionally, the terminal performs a cascading operation based on the first timer, including:

the terminal starts a first timer under the condition that a data packet of a target service is received from an upper layer;

under the condition that the first timer is overtime, the terminal executes cascading operation on the data packet of the target service received in the target time period;

The target time period is a time period from the start of the first timer to the timeout.

For example, when the terminal PDCP receives PDCP SDU #1 from the upper layer, the first timer is started, and when PDCP receives PDCP SDU #2 and PDCP SDU #3 from the upper layer during the operation of the concatenation timer, PDCP concatenates three data packets, PDCP SDU #1, PDCP SDU #2, and PDCP SDU #3, into one PDCP SDU. In this way, the terminal can better implement the concatenation processing of the data packets by means of the timing of the first timer.

Optionally, the method further comprises:

and under the condition that the first timer is operated, if the terminal receives the data packet of the target service from the upper layer, the terminal does not restart the first timer.

That is, in the operation time period from the start of the first timer to the timeout of the first timer, the terminal performs the cascade operation on the data packet received in the operation time period, and the terminal does not restart the first timer, so as to avoid the confusion of the cascade operation of the terminal caused by the re-timing of the first timer.

Optionally, the method further comprises any one of the following:

the terminal resets and starts the first timer under the condition that the first data packet associated with the next cascade data packet arrives;

The terminal starts a new first timer in case the first packet associated with the next concatenated packet arrives.

It should be noted that one first timer may be associated with a plurality of concatenated data packets (or the first timer may be common to a plurality of concatenated data packets). It will be appreciated that in one case, the timer value of the first timer is configured based on granularity of the radio bearer, and the same first timer is used for each of the plurality of concatenated data packets corresponding to the radio bearer. Or it may be that a first timer is associated with a concatenated packet (or that the first timer is not common to a plurality of concatenated packets). It will be appreciated that in one case, the timer value of the first timer is configured based on the granularity of the radio bearer, a different first timer is used for the plurality of concatenated data packets corresponding to the radio bearer, but the timer values of the different first timers may be the same.

For example, one first timer is associated with L concatenated data packets, or L first timers are associated with L concatenated data packets one by one, L being an integer greater than 1.

For example, in the case where a first timer is associated with each concatenated packet (it will be understood that the first timer is common to a plurality of concatenated packets), upon arrival of a first packet belonging to a next concatenated packet, the terminal performs a reset and start operation on the first timer to thereby time the next concatenated packet. Illustratively, in the operation period from when the first timer starts to timeout, the terminal PDCP concatenates the three received packets of PDCP sdu#1, PDCP sdu#2, PDCP sdu#3 into one PDCP SDU, and when PDCP receives PDCP sdu#4 from the upper layer, the terminal performs a reset (e.g., reset to 0) and restarts operation on the first timer to restart the timing of a new round.

Alternatively, in the case where a first timer is associated with a concatenated packet (it will be understood that the first timer is not common to multiple concatenated packets), the terminal starts a new first timer when the first packet belonging to the next concatenated packet arrives. Illustratively, in the operation period from the start of the first timer to the timeout, the terminal PDCP starts a new first timer when PDCP receives PDCP SDU #4 from an upper layer after concatenating three data packets of received PDCP SDU #1, PDCP SDU #2, PDCP SDU #3 into one PDCP SDU.

In the embodiment of the application, the terminal executes the cascade operation on the data packet of the target service received in the target time period through the first timer, so that the data packet can be better processed by means of the first timer.
