UPF network element carries out RQI label to downlink data packet according to the SDF that SMF network element is sent, by the downlink data after label Packet is sent to RAN, and RAN carries out RQI label when decapsulating the data packet for the carrying RQI that UPF network element is sent.

Step S205, terminal device determines second according to the information of the first reflection QoS timer for the QoS rule of derivation Reflect QoS timer.

After terminal device receives the downlink data packet of carrying RQI of RAN transmission, if terminal device does not store accordingly The QoS rule of derivation then generates the QoS rule of a derivation.If the QoS rule that terminal device storage is derived from accordingly, Need to reset the reflection QoS timer of the QoS rule of the derivation.Then, the letter that terminal device reflects QoS timer according to first Breath determines the second reflection QoS timer for the QoS rule of derivation, and the value of the second reflection QoS timer is no more than the first reflection The value of QoS timer, the value of the second reflection QoS timer include: the first reflection no more than the value of the first reflection QoS timer The value of QoS timer reflects the value of QoS timer less than first, alternatively, the value of the first reflection QoS timer is equal to the first reflection The value of QoS timer.

In a kind of mode, terminal device can be when receiving the information of the first reflection QoS timer, according to the first reflection The information of QoS timer generates one or more reflection QoS timers, and the value for the reflection QoS timer that terminal device generates is small In the value of the first reflection QoS timer, terminal device can reflect the information storage of the reflection QoS timer of generation to one It can also include the information of the first reflection QoS timer in QoS timer entry, in the reflection timer entry.It is subsequent, work as end When end equipment generates the reflection QoS timer of the QoS rule of the QoS rule or resetting derivation that derive from, from the reflection timer The second reflection QoS timer is determined for the QoS rule that derives from list, and the value that the 2nd QoS reflects timer is less than or equal to the The value of one reflection QoS timer.

In another way, the not pre-generated reflection QoS timer entry of terminal device, but generate and send in terminal device When the reflection QoS timer for the QoS rule that raw QoS rule or resetting are derived from, in real time according to the first reflection QoS timer Value generate second reflection QoS timer.

In the present embodiment, terminal device can be when generating the QoS rule derived from, according to the first reflection QoS timer Information determines the second reflection QoS timer for the QoS rule of derivation, true so as to the QoS rule flexibly for different derivations Fixed different reflection QoS timer.Terminal device can also be in the reflection QoS timer for the QoS rule that resetting is derived from, for group Raw QoS rule determines the second reflection QoS timer, so as to be dynamically the QoS of derivation in PDU session operational process The suitable reflection QoS timer of rule selection.Since the reflection QoS timer of PDU session is dynamically, this can prevent from generating The QoS of too many derivation is regular and cannot delete in time.

In a kind of exemplary approach, terminal device is according to the information of the first reflection QoS timer and reflection QoS timer Selection strategy determines the second reflection QoS timer for the QoS rule of derivation.Wherein, the selection strategy for reflecting QoS timer can To be that SMF network element is sent to terminal device, it is also possible to be pre-configured on the terminal device.

Optionally, the selection strategy of reflection QoS timer includes any one in following strategy: what PDU session generated The byte-sized of the QoS rule of derivation and the corresponding relationship of reflection QoS timer, the QoS rule for the derivation that PDU session generates The corresponding relationship of number and the value of reflection QoS timer, the mark and the value of reflection QoS timer of the QoS flow that PDU session includes Corresponding relationship.It is appreciated that the selection strategy of reflection QoS timer is not limited to strategy described above, and it is fixed to reflect QoS When device the form of selection strategy be not limited to the form of list, the selection strategy of QoS timer is reflected in the embodiment of the present application It is described using tabular form.

Table one is a kind of schematic diagram for reflecting the selection strategy of QoS timer, and table one is as follows:

Table one

Reflect the value of QoS timer	The byte-sized of the QoS rule for the derivation that PDU session generates
		Reflect the value of QoS timer 1	0 byte to 500 bytes
Reflect the value of QoS timer 2	501 bytes to 1000 bytes
		Reflect the value of QoS timer 3	1001 bytes to 2000 bytes

In selection strategy shown in table one, the value of difference reflection QoS timer is different, the derivation that PDU session generates in table one The size of QoS rule refer to the byte of the QoS rule of derivation for currently having generated and having stored, it is generally the case that PDU session production The byte of the QoS rule of raw derivation is bigger, it should which the value of the reflection QoS timer of selection is with regard to smaller, to ensure that In the low memory of terminal device, the QoS rule of the derivation of redundancy is quickly deleted.Therefore, QoS timer 1 is reflected in table one Value > reflection QoS timer 2 value > reflection QoS timer 3 value.The QoS rule derived from is being deleted, it can be according to derivation The sequencing of expiration time of reflection QoS timer of QoS rule successively delete.It should be noted that choosing shown in table one The byte-sized for selecting the QoS rule derived from strategy is merely illustrative, and is not constituted a limitation, the byte of the QoS rule of derivation Size can change.In addition, the number for the reflection QoS timer for including in the selection storage of reflection QoS timer is also not necessarily limited to It can also include more or fewer reflection QoS timers 3 shown in table one.

Selection strategy shown in the byte-sized and table one of the QoS rule for the derivation that terminal device is generated according to PDU session, The second reflection QoS timer is determined for the QoS rule of the derivation of generation.Illustratively, when terminal device is that PDU session generates the When the QoS rule of one derivation, it is assumed that the size of the QoS rule for all derivations that session has currently been generated and stored is 150 bytes, Then terminal device selection strategy according to shown in table one determines the reflection QoS timer of the QoS rule of the first derivation for reflection QoS timer 1.When terminal device is that PDU session generates the QoS rule that second derives from, it is assumed that session has currently been generated and deposited The size of the QoS rule of all derivations of storage is 600 bytes, then terminal device selection strategy according to shown in table one, determines the The reflection QoS timer of the two QoS rules derived from is reflection QoS timer 2.When terminal device is that PDU session generates third group When raw QoS rule, it is assumed that the size of the QoS rule for all derivations that session has currently been generated and stored is 1600 bytes, then Terminal device selection strategy according to shown in table one determines the reflection QoS timer for the QoS rule that third derives from for reflection QoS Timer 3.

Table two is another schematic diagram for reflecting the selection strategy of QoS timer, and table two is as follows:

Table two

Reflect the value of QoS timer	The number of the QoS rule for the derivation that PDU session generates
		Reflect the value of QoS timer 1	0 to 200
Reflect the value of QoS timer 2	201 to 500
		Reflect the value of QoS timer 3	501 to 1000

Selection strategy shown in the number and table two of the QoS rule for the derivation that terminal device is generated according to PDU session, for group Raw QoS rule determines the second reflection QoS timer.The QoS rule for the derivation that PDU session generates in selection strategy shown in table two Number may include the QoS rule for the derivation being currently generated, and can not also include the QoS rule for the derivation being currently generated.For example, For terminal device when generating the QoS rule that third derives from, terminal device has stored the QoS rule of 200 derivations, if table two The number of the QoS rule for the derivation that PDU session generates in shown selection strategy includes the QoS rule for the derivation being currently generated, then The number of the QoS rule for the derivation that PDU session generates is 201, and terminal device selection strategy according to shown in table two determines third The reflection QoS timer of the QoS rule of derivation is reflection QoS timer 2, if PDU session produces in selection strategy shown in table two The number of the QoS rule of raw derivation does not include the QoS rule for the derivation being currently generated, the then QoS for the derivation that PDU session generates The number of rule is 200, according to selection strategy shown in table two, determines that the reflection QoS timer for the QoS rule that third derives from is Reflect QoS timer 1.It should be noted that of the QoS rule for the derivation that PDU session generates in selection strategy shown in table two Number is merely illustrative, and is not constituted a limitation, and the number of the QoS rule for the derivation that PDU session generates can change.In addition, anti- It penetrates the number of reflection QoS timer for including in the selection storage of QoS timer and is also not necessarily limited to shown in table two 3, it can be with Including more or fewer reflection QoS timers.

Terminal device reflects the selection strategy of QoS timer according to shown in table two, is that the QoS rule of different derivations determines Reflection QoS timer value it is different.Under normal conditions, the number of the QoS rule for the derivation that PDU session generates is bigger, PDU meeting The memory for talking about the terminal device occupied is bigger, so when selection strategy is arranged, the QoS rule for the derivation that PDU session generates Number is bigger, and the value of corresponding reflection QoS timer is smaller, so as to ensure in the low memory of terminal device, quickly Delete the QoS rule of the derivation of redundancy.Therefore, in table two, reflect QoS timer 1 value > reflection QoS timer 2 value > instead Penetrate the value of QoS timer 3.

According to selection strategy shown in table two, different reflection QoS can not only be selected fixed for the QoS rule of different derivations When device, additionally it is possible to dynamically adjust the reflection QoS timer of the QoS rule of the same derivation.For example, terminal device is generating the When the QoS rule of one derivation, the reflection QoS timer that the QoS rule derived from for first determines is reflection QoS timer 1, it is assumed that The value for reflecting QoS timer 1 is 10 seconds, and when reflecting 1 timing of QoS timer by 7 seconds, terminal device receives a lower line number According to packet, and the QoS rule of the corresponding derivation of the downlink data packet is the first QoS rule derived from, then terminal device needs to reset The reflection QoS timer of the first QoS rule derived from, at this point, if the number of the QoS rule for the derivation that PDU session generates is 400, then the reflection QoS timer for the QoS rule that first derives from is reset to reflection QoS timer 2, i.e. basis by terminal device The number of the QoS rule for the derivation that PDU session generates reduces the value of the reflection QoS timer of the QoS rule of the first derivation.It needs It is noted that at this point, terminal device can only reset to the value of the reflection QoS timer for the QoS rule that first derives from instead The value of QoS timer 2 is penetrated, the value of the reflection QoS timer of the QoS rule of all derivations of storage can also all be reset to instead Penetrate the value of QoS timer 2.

Table three is another schematic diagram for reflecting the selection strategy of QoS timer, and table three is as follows:

Table three

QFI can uniquely indicate a QoS flow, include QFI in the QoS rule for the derivation that terminal device generates, terminal is set The standby selection strategy according to shown in table three can select different reflection QoS for the QoS rule of the corresponding derivation of different QoS stream Timer, for example, when terminal device generate first derive from QoS rule in include QFI be QFI2 when, terminal device according to Selection strategy shown in table three, the reflection QoS for the QoS rule for selecting the corresponding reflection QoS timer 2 of QFI2 to derive from as first Timer.When the QFI for including in the second QoS rule derived from that terminal device generates is QFI3, terminal device is according to figure three Shown in selection strategy, the reflection QoS for the QoS rule for selecting the corresponding reflection QoS timer 3 of QFI3 to derive from as second is periodically Device.The value for reflecting QoS timer can be set with reference to the time delay of QoS flow, and the delay requirement of the corresponding QoS flow of different Q FI is different Sample, therefore, the value of the corresponding reflection QoS timer of different Q FI are different.Illustratively, the time delay of QoS flow is bigger, and reflection QoS is fixed When device value it is bigger, the time delay of QoS flow is shorter, reflect QoS timer value it is smaller.

In another exemplary approach, terminal device is according to the information of the first reflection QoS timer and the transmission of Business Stream Mode determines the second reflection QoS timer for the QoS rule of derivation.Correspondingly, terminal device needs to carry out business detection, obtain Take the transmission mode of Business Stream, the transmission mode of Business Stream may include the frequency of giving out a contract for a project of Business Stream, business duration or One or more of the gap of person's received data packet.For example, it is high (wrap send or receive gap short) for sending frequency, The Business Stream of business duration length, the biggish reflection QoS timer of terminal device selective value；For sending, frequency is low (to be wrapped To send or receive gap long), business duration short Business Stream, the lesser reflection QoS timer of terminal device selective value. For example, when terminal device detects that the business of certain IP five-tuple was given out a contract for a project with 10-30 seconds frequencies, and the business duration is up to 10- At 20 minutes, 40 seconds or so reflection QoS timers are selected, when the business of certain IP five-tuple was given out a contract for a project with -60 seconds 50 seconds frequencies, and When the business duration is 1 minute, then 1 minute or so reflection QoS timer is selected.

In the present embodiment, terminal device be derive from QoS rule determine the second reflection QoS timer after, it is subsequent, use this The QoS rule of derivation sends upstream data packet.After the reflection QoS timer of the QoS rule of the derivation expires, the derivation is deleted QoS rule.Upstream data packet is sent to RAN by terminal device, and upstream data packet is sent to UPF network element, UPF network element by RAN After receiving the upstream data packet from terminal device, QFI verifying is carried out.

In the present embodiment, terminal device receives the information of the first reflection QoS timer from SMF network element, according to first The information for reflecting QoS timer, determines the second reflection QoS timer for the QoS rule of derivation, wherein the second reflection QoS timing Value of the value of device no more than the first reflection QoS timer.It is fixed according to the first of SMF network element configuration the reflection QoS that terminal device passes through When device determine the second reflection timer, so as to flexibly determine different reflection QoS timings for the QoS rule of different derivations Device avoids the QoS rule of useless derivation from accounting for so that the reflection QoS timer of the QoS rule derived from can adapt to business feature Memory source and the frequent process resource deleted or generate derivation QoS rule occupied terminal equipment with terminal device.

Fig. 3 is the signaling process figure for the communication means that the embodiment of the present application two provides, what is different from the first embodiment is that this reality Apply the information that SMF network element in example has sent at least two reflection QoS timers to terminal device.As shown in figure 3, the present embodiment mentions The method of confession the following steps are included:

Step S301, PCF network element sends PCC rule to SMF network element, includes at least two reflection QoS fixed in PCC rule When device information.

PCF network element can send PCC rule to SMF network element in the establishment process of PDU session or during modification, should The information of at least two reflection QoS timers is carried in PCC rule, the information of at least two reflections timer can be with reflection The form of QoS timer entry is sent, and the information of at least two reflections QoS timer, which can be, is pre-configured in PCF network element On.Optionally, the selection strategy that reflection QoS timer is also carried in PCC rule, reflects the selection strategy of QoS timer Reflection QoS timer is determined for terminal device.

Wherein, step S301 is optional step.When PCF network element is not disposed, PCC rule can be pre-configured in SMF net In member, alternatively, SMF network element obtains PCC rule from UDM network element.

Step S302, SMF network element sends the information of at least two reflection QoS timers to terminal device.

Step S303, SMF network element to UPF network element send at least two reflection QoS timers information or this at least two The information of a maximum reflection QoS timer of reflection QoS timer intermediate value.

Wherein, step S302 and step S303 also may be performed simultaneously when being executed without sequencing.If PCC is advised The selection strategy of reflection QoS timer is carried in then, then SMF network element sends the selection plan of reflection QoS timer to terminal device Slightly, SMF network element can also send the selection strategy of reflection QoS timer to UPF network element.

The information of at least two reflections QoS timer or at least two reflections QoS timer intermediate value are maximum anti- The information for penetrating QoS timer carries out the QFI verifying of upstream data packet for UPF network element.When SMF network element is sent to UPF network element When the information of few two reflections QoS timer, UPF network element is maximum from least two reflections, one value of QoS timer selection QoS timer is reflected, is generated with reference to reflection QoS timer, the value of the reference reflection QoS timer is greater than the maximum reflection of the value QoS timer.When SMF network element sends the maximum reflection QoS timing of at least two reflections QoS timer intermediate value to UPF network element When the information of device, UPF is generated directly according to the maximum reflection QoS timer of the value with reference to reflection QoS timer.When UPF network element After sending the corresponding downlink data packet of QFI1 to terminal device, reference reflection QoS timer is opened, when UPF network element is in the ginseng When receiving the upstream data packet of terminal device transmission before examining reflection QoS timer expiry, judge that the upstream data packet is corresponding QFI whether be QFI1, when the corresponding QFI of upstream data packet be QFII when, then be verified.

Step S303 is optional step, and the value of reference reflection QoS timer can be operator's configuration.In addition, step Rapid S302 and S303 also may be performed simultaneously when being executed without sequencing.

Step S304, UPF network element sends downlink data packet to terminal device, carries RQI in the downlink data packet.

Step S305, terminal device determines reflection QoS from least two reflection QoS timers for the QoS rule of derivation Timer.

After terminal device receives the downlink data packet of carrying RQI of RAN transmission, if terminal device does not store accordingly The QoS rule of derivation then generates the QoS rule of a derivation.If the QoS rule that terminal device storage is derived from accordingly, Need to reset the reflection QoS timer of the QoS rule of the derivation.Then, terminal device is according at least two reflection QoS timers Information, from least two reflection QoS timers in for derive from QoS rule determine reflection QoS timer.

In a kind of exemplary approach, selection strategy and at least two reflections of the terminal device according to reflection QoS timer The information of QoS timer, the QoS rule derived from from least two reflection QoS timers determine reflection QoS timer.It should The selection strategy of reflection QoS timer can be SMF network element and be sent to terminal device, is also possible to be pre-configured in terminal and sets It is standby upper.

Optionally, the selection strategy of reflection QoS timer includes any one in following strategy: PDU session generates Derivation QoS rule byte-sized and reflection QoS timer value corresponding relationship, PDU session generate derivation QoS rule The corresponding relationship of the value of number and reflection QoS timer then, the mark and reflection QoS timer of the QoS flow that PDU session includes Value corresponding relationship.

In another exemplary approach, terminal device is fixed according to the transmission mode of Business Stream and at least two reflection QoS When device information, from least two reflection QoS timers in for derive from QoS rule determine reflection QoS timer.Correspondingly, Terminal device needs to carry out business detection, obtains the transmission mode of Business Stream.

The specific implementation of above two mode is no longer gone to live in the household of one's in-laws on getting married here referring to the associated description of step S202 in embodiment one It states.

In the present embodiment, terminal device be derive from QoS rule determine reflection QoS timer after, it is subsequent, use the derivation QoS rule send upstream data packet.After the reflection QoS timer of the QoS rule of the derivation expires, the derivation is deleted QoS rule.

Upstream data packet is sent to RAN by terminal device, and upstream data packet is sent to UPF network element by RAN, and UPF network element connects Receive the upstream data packet from terminal device after, according to SMF network element send at least two reflection QoS timers information or The information of the maximum reflection QoS timer of at least two reflections QoS timer intermediate value, carries out the QFI verifying of upstream data packet.

In the present embodiment, terminal device receives the information of at least two reflection QoS timers from SMF network element, according to The information of at least two reflection QoS timers, the QoS rule derived from from at least two reflections QoS timer determine one A reflection QoS timer.By the way that for the multiple reflection QoS timers of terminal equipment configuration, terminal device can be flexibly difference The QoS rule of derivation determines different reflection QoS timers, so that the reflection QoS timer of the QoS rule derived from can adapt to Business feature avoids the memory source of the QoS rule occupied terminal equipment of useless derivation and frequently deletes or generate to derive from The process resource of QoS rule occupied terminal equipment.

Fig. 5 is the schematic diagram of another network architecture that present patent application provides, referring to Fig.1 and Fig. 5, with net shown in Fig. 1 Unlike network framework: further include in the network architecture shown in Fig. 5 network data analysis equipment (network data analytic, NWDA), NWDA can determine different data network name (data network name, DNN) by a large amount of data statistics Rough type of service, thus according to type of service determine DNN and reflect QoS timer information mapping relations, and will The mapping relations of the information of DNN and reflection QoS timer are sent to PCF, select for PCF network element, wherein wrap in the mapping relations It includes at least one DNN and reflects the mapping relations of the information of QoS timer, the corresponding at least two reflections QoS timer of each DNN Information, between NWDA network element and PCF network element by interface (such as N23 interface) communicate.

Fig. 4 is the signaling process figure for the communication means that the embodiment of the present application three provides, provided in this embodiment referring to Fig. 4 Method the following steps are included:

Step S401, NWDA sends DNN to PCF network element and reflects the mapping relations of QoS timer entry.

NWDA obtains different DNN and reflects the information MAP relationship of QoS timer by the collection and analysis of data, wherein One DNN can correspond to multiple reflection QoS timers, optionally, the information of the corresponding multiple reflection QoS timers of a DNN Can exist in the form of reflecting QoS timer entry, with the mapping of the information of DNN and reflection QoS timer in the present embodiment Relationship is illustrated for being DNN and the mapping relations of reflection QoS timer entry.

NWDA obtains DNN and reflects after the mapping relations of the information of QoS timer, by DNN and reflects QoS timer The mapping relations of information are sent to PCF network element.When the information MAP relationship of DNN and reflection QoS timer is using DNN and reflection When the mapping relations of QoS timer entry, the mapping relations of DNN and reflection QoS timer entry are sent to PCF net by NWDA Member.Optionally, the mapping relations of DNN and reflection QoS timer entry use list mode, then NWDA determines DNN and reflection QoS When device list mapping relations PCF network element is sent in the form of list, as shown in following tables four:

Table four

Reflect QoS timer entry	DNN
		Reflect QoS timer entry 1	DNN1
Reflect QoS timer entry 2	DNN2
		Reflect QoS timer entry 3	DNN3

It as shown in table 4, include the corresponding relationship of three DNN and reflection QoS timer entry, each reflection QoS in the table It include the information of at least two reflection QoS timers in timer entry.

Step S402, PCF network element sends PCC rule to SMF network element, includes reflection QoS timer column in PCC rule Table.

PCF network element receives and saves DNN and reflects the mapping relations of QoS timer entry, the subsequent foundation in PDU session In the process or during modification, PCF network element from DNN and reflects QoS timer entry according to the type of service of terminal device A reflection QoS timer entry is selected in mapping relations, and the reflection QoS timer entry of selection is carried in PCC rule It is sent to SMF network element.The reflection QoS timer column of the current PDU session established or modified can be only included in PCC rule Table also may include the reflection QoS timer entry of multiple PDU sessions, and the reflection QoS timer entry of different PDU sessions can It can be different.Optionally, the selection strategy of reflection QoS timer is carried in PCC rule.

Step S403, SMF network element sends reflection QoS timer entry to terminal device.

Reflection QoS timer entry in PCC rule is sent to terminal device by SMF network element, reflection QoS timer column It include the information of at least two reflection QoS timers in table.

Step S404, SMF network element sends reflection QoS timer entry or reflection QoS timer entry to UPF network element The information of the maximum reflection QoS timer of intermediate value.

The letter of reflection QoS timer entry or the maximum reflection QoS timer of reflection QoS timer entry intermediate value Breath carries out the QFI verifying of upstream data packet for UPF network element.When SMF network element sends reflection QoS timer entry to UPF network element When, UPF network element selects the maximum reflection QoS timer of value from reflection QoS timer entry, generates with reference to reflection QoS timer, this is greater than the maximum reflection QoS timer of the value with reference to the value for reflecting QoS timer.When SMF network element is to UPF net When member sends the information of the maximum reflection QoS timer of reflection QoS timer entry intermediate value, UPF is directly according to value maximum Reflection QoS timer, generate with reference to reflection QoS timer.When UPF network element sends the corresponding lower line number of QFI1 to terminal device After packet, reference reflection QoS timer is opened, when UPF network element receives end before QoS timer expiry is reflected in the reference When the upstream data packet that end equipment is sent, judge whether the corresponding QFI of the upstream data packet is QFI1, when upstream data packet is corresponding QFI be QFII when, then be verified.

Wherein, step S403 and step S404 also may be performed simultaneously when being executed without sequencing.If PCC is advised The selection strategy of reflection QoS timer is carried in then, then SMF network element sends the selection plan of reflection QoS timer to terminal device Slightly, SMF network element can also send the selection strategy of reflection QoS timer to UPF network element.

Step S404 is optional step, when SMF network element does not send reflection QoS timer entry to UPF network element or this is anti- When penetrating the information of the maximum reflection QoS timer of QoS timer entry intermediate value, QoS timer is reflected in reference that UPF is used can be with It is that operator is preconfigured.

Step S405, UPF network element sends downlink data packet to terminal device, carries RQI in the downlink data packet.

Step S406, terminal device determines reflection QoS timing from reflection QoS timer entry for the QoS rule of derivation Device.

After terminal device receives the downlink data packet of carrying RQI of RAN transmission, if terminal device does not store accordingly The QoS rule of derivation then generates the QoS rule of a derivation.If the QoS rule that terminal device storage is derived from accordingly, Need to reset the reflection QoS timer of the QoS rule of the derivation.Then, terminal device is group from reflection QoS timer entry Raw QoS rule determines reflection QoS timer.Terminal can reflect in QoS timer entry in PDU ession for telecommunication dynamic select Any reflection QoS timer, and UPF using reflection QoS timer entry in maximum value carry out QFI verifying, to ensure end Before end equipment deletes the QoS rule derived from, upstream data packet will not be abandoned.

In a kind of exemplary approach, terminal device is according to the selection strategy of reflection QoS timer, from reflection QoS timing The determining reflection QoS timer of QoS rule in device list to derive from.The selection strategy of reflection QoS timer can be SMF net Member is sent to terminal device, is also possible to be pre-configured on the terminal device.

In another exemplary approach, terminal device is according to the transmission mode of Business Stream, from reflection QoS timer entry In for derive from QoS rule determine reflection QoS timer.Correspondingly, terminal device needs to carry out business detection, Business Stream is obtained Transmission mode.

In the present embodiment, NWDA obtains the rough type of service of different DNN, thus root by a large amount of data statistics It provides corresponding reflection QoS timer entry according to type of service for DNN to select for PCF network element, PCF network element is according to terminal device Business feature selects a reflection QoS timer entry from multiple reflection QoS timer entries for terminal device, and will selection Reflection QoS timer entry be sent to SMF network element.The reflection QoS timer entry of PCF selection can be with the industry of terminal device Business characteristics match avoids useless derivation so that the reflection QoS timer of the QoS rule derived from can adapt to business feature The memory source of QoS rule occupied terminal equipment and the processing for frequently deleting or generating derivation QoS rule occupied terminal equipment Resource.

Fig. 6 is the signaling process figure for the communication means that the embodiment of the present application four provides, as shown in fig. 6, the present embodiment provides Method the following steps are included:

Step S601, SMF network element and PCF network element conversate management strategy (Session Management Policy) It establishes, PCF network element is sent to SMF network element for QoS timer entry is reflected in establishment process.

Before step S601, terminal device triggers the foundation of PDU session, and SMF network element is that terminal device selects PCF, from The foundation that terminal device triggers PDU session includes multiple steps, detailed process during being terminal device selection PCF to SMF It can refer to existing PDU session establishment process, the present embodiment is no longer described in detail.

Optionally, session management strategy establishment process the following steps are included: SMF network element to PCF network element send request message, The request message is used for queued session management strategy information, and PCF network element sends response message to SMF network element, in the response message Session management policy information is carried, includes reflection QoS timer entry, reflection QoS timer in session management policy information It include the information of at least two reflection QoS timers in list.It certainly, further include other plans in the session management policy information It omits, such as the peak transfer rate and QoS information of terminal device.

Step S602, SMF network element is that terminal device selects UPF network element.

The PCC rule that SMF network element can be sent according to PCF network element is that terminal device selects UPF network element.It needs to illustrate It is that SMF network element can not also select UPF network element according to PCC rule, correspondingly, step S601 can be executed after S602.

Step S603, SMF network element sends session establishment/modification to UPF network element and requests (Session Establishment/ Modification Request), it include reflection QoS timer entry in the request of the session establishment/modification.

Optionally, the reflection QoS timer entry for including in the session establishment/modification request could alternatively be reflection QoS The information of the maximum reflection QoS timer of timer entry intermediate value.The request of the session establishment/modification can for N4 session establishment/ Modification request.

Step S604, UPF network element sends session establishment/modification to SMF network element and responds (Session Establishment/ Modification Response)。

Step S605, SMF network element sends communication N1N2 to AMF network element and transmits message (Communication N1N2Message Transfer), it includes reflection QoS timer entry that communication N1N2, which is transmitted in message,.

Communication N1N2 transmission message is used to carry the upper style of writing information of PDU session, transmits in the present embodiment in communication N1N2 Reflection QoS timer entry is carried in message, so that AMF network element is sent to terminal for QoS timer entry is reflected by RAN Equipment.

Step S606, AMF network element sends PDU session request (PDU Session Request) to RAN, which asks It include reflection QoS timer entry in asking.

It further include Non-Access Stratum (Non-access stratum, NAS) message in the PDU session request, which asks Asking can be N2PDU session request.

Step S607, RAN and terminal device carry out access net-specific resources and establish (AN-specific resource Setup), reflection QoS timer entry is sent to terminal device in establishment process by RAN.

PDU Establishing process after step S607 is same as the prior art, and which is not described herein again.

In the present embodiment, S601 to S607 is handed down to terminal device to reflection QoS timer entry through the above steps, above-mentioned Information or at least two reflection QoS for issuing the first reflection QoS timer that process is equally applicable in above-described embodiment are fixed When device information issue.

Fig. 7 is the signaling process figure for the communication means that the embodiment of the present application five provides, as shown in fig. 7, the present embodiment provides Method the following steps are included:

Step S701, terminal device determination can not increase the QoS rule of derivation newly.

Terminal device can not increase newly derivation QoS rule, it can be understood as terminal device, can not newly-generated derivation QoS Rule.Terminal device can at least one condition in following condition when meeting determination can not increase the QoS rule of derivation newly: (1) quantity of the QoS rule for the derivation that some PDU session of terminal device generates is greater than preset first threshold；(2) terminal is set The sum for the derivation QoS rule that standby all PDU sessions generate is greater than preset second threshold, may establish on terminal device Multiple PDU sessions；(3) memory usage of some PDU session of terminal device is greater than preset third threshold value；(4) terminal is set The occupancy of standby memory is greater than preset 4th threshold value.

Terminal device can be periodically detected the QoS rule that whether can not increase derivation newly, can also derive from each generate QoS rule when, detect whether can not to increase newly the QoS rule of derivation.

Step S702, terminal device sends upstream data packet to UPF network element, which is used to indicate terminal device The QoS rule of derivation can not be increased newly.

In the present embodiment, terminal device notifies UPF network element that can not increase the QoS rule of derivation newly by user face data, shows Example property, terminal device can notify UPF network element itself that can not increase the QoS rule of derivation newly by following several modes:

(1) in upstream data packet QoS flow be identified as derivation default QoS regular (default QoS rule) it is corresponding The corresponding QoS flow of default QoS rule that QoS flow mark perhaps defaults the corresponding traffic identifier derivation of QoS rule identifies or should The corresponding traffic identifier of default QoS rule, which is used to indicate terminal device, can not increase the QoS rule of derivation newly.

Terminal device first selects the Business Stream in a PDU session, and the PDU session of terminal device selection can be derivation The most maximum PDU session of PDU session or committed memory of QoS rule, Business Stream are distinguished by packet filter.Eventually The default QoS rule that the QFI of the upstream data packet of the Business Stream of the PDU session of selection is replaced with derivation by end equipment is corresponding The QFI or corresponding QFI of default QoS rule.Table five is the schematic diagram of the QoS rule of the PDU session 1 of terminal device, and table five is such as Shown in lower:

Table five

Terminal device, can be according to the anti-of the QoS rule derived from the PDU session when selecting the Business Stream of PDU session QoS timer is penetrated to select from small to large, after can guarantee that UPF network element carries out RQI label not in downlink data packet in this way, reflection QoS timer can expire faster, to quickly delete the QoS rule of derivation.For example, terminal device selection PDU session 1 The corresponding Business Stream of Packet Filter1 and Packet Filter2, terminal device is Packet Filter1 and Packet The QFI of the corresponding upstream data packet of Filter2 is labeled as the corresponding QFI4 of default QoS rule or default QoS rule derived from Corresponding QFI5 is transferred to by the corresponding Data Radio Bearer of QFI4 or QFI5 (Data Radio Bearer, DRB) RAN.When UPF receives Packet Filter 1 and the corresponding upstream data packet of Packet Filter 2, upstream data packet is determined QFI be QFI4 or QFI5, QFI1 and QFI2 corresponding with SDF on UPF is inconsistent, then judges that terminal device can not be new accordingly Send raw QoS rule.

(2) upstream data packet is empty data packet, which, which is used to indicate terminal device, can not increase the QoS rule of derivation newly Then.

Terminal device first selects the Business Stream in a PDU session, the concrete mode of selection mode reference method (1).So Afterwards, terminal device constructs an empty data packet, and the packet header of the sky data packet carries the Packet Filter letter of the Business Stream of selection It ceases (for example, IP five-tuple).For the PDU session shown in the table five, it is assumed that terminal device select Packet Filter and Then the corresponding Business Stream of Packet Filter2 generates the corresponding Business Stream of Packet Filter1 and Packet Filter2 Empty data packet, empty data packet is sent to UPF network element.UPF network element is according to receiving Packet Filter1 and Packet The corresponding empty data packet of Filter2 determines that terminal device can not increase the QoS rule of derivation newly.

(3) instruction information is carried in upstream data packet, which, which is used to indicate terminal device, can not increase derivation newly QoS rule.

Terminal device first selects the Business Stream in a PDU session, the concrete mode of selection mode reference method (1).So Afterwards, terminal device generates the upstream data packet of the Business Stream of the PDU session of selection, can carry in the packet header of the upstream data packet Indicate information.For the PDU session shown in the table five, terminal device selects Packet Filter1 and Packet Filter2 corresponding Business Stream, terminal device send Packet Filter1 and Packet Filter2 correspond in upstream data packet carry indicate Information, instruction terminal equipment can not increase the QoS rule of derivation newly.UPF network element is according to receiving Packet Filter1 and Packet The instruction information carried in the corresponding upstream data packet of Filter 2 judges that terminal device can not increase the QoS rule of derivation newly.

Step S703, UPF network element sends the first instruction information to SMF network element, which is used to indicate terminal Equipment can not increase the QoS rule of derivation newly.

UPF network element receive terminal device transmission upstream data packet after, according to upstream data packet determine terminal device without The newly-increased QoS rule derived from of method, further sends the first instruction information to SMF network element, instruction terminal equipment can not increase derivation newly QoS rule.

Step S704, SMF network element sends second indication information to UPF network element, which is used to indicate UPF net Member stops carrying out RQI label to the business of terminal device.

UPF network element marks the downlink data packet for being sent to terminal device without RQI, phase according to second indication information It answers, after terminal device receives downlink data packet, due to not carrying RQI in downlink data packet, then will not generate new group Raw QoS rule, and the reflection QoS timer of the QoS rule of stored derivation will not being reset, when having stored The reflection QoS timer timing of QoS rule of derivation when reaching, terminal device deletes the QoS rule derived from.Work as terminal device After the quantity of the QoS rule of the derivation of storage is reduced, SMF network element can send SDF to UPF network element again within a preset time With RQI information, indicate that UPF network element carries out RQI label to the corresponding downlink data packet of SDF.Correspondingly, terminal device is according to downlink The RQI information carried in data generates the QoS rule derived from, and terminal device handles reflection QoS again.

In the present embodiment, terminal device determination can not increase the QoS rule of derivation newly, then send upstream data to UPF network element Packet, which, which is used to indicate terminal device, can not increase the QoS rule of derivation newly, so that UPF network element notifies SMF network element Terminal device can not increase the QoS rule of derivation newly, SMF network element further indicate UPF network element stop to the business of terminal device into Row RQI label, so that terminal device can be automatically deleted the QoS rule of derivation.

It should be noted that the method for the present embodiment can be implemented in based on the above embodiment one to example IV method Example one, when terminal device receives downlink data packet, can be generated according to downlink data packet and be derived from into the method for example IV QoS rule, be then that the QoS rule of the derivation determines reflection QoS timer, and the method for the present embodiment can be applied at end End equipment generate derive from QoS rule before, terminal device judge after receiving downlink data packet terminal device whether without The newly-increased QoS rule derived from of method, and then the method for executing the present embodiment.

The method of the present embodiment can also individually be implemented independently of the scheme of embodiment one to example IV.For example, terminal Device periodically detects whether that the QoS rule of derivation can not be increased newly, if it is determined that the QoS rule that can not increase derivation newly then executes The method of the present embodiment, to delete the QoS rule of partial derivation, when the quantity of the QoS rule of the derivation of terminal device storage subtracts After few, the reflection QoS timer of the QoS rule derived from is still determined using the method for above-described embodiment one to example IV.

Fig. 8 is the signaling process figure for the communication means that the embodiment of the present application six provides, as shown in figure 8, the present embodiment provides Method the following steps are included:

Step S801, SMF network element sends the QoS fuzzy rules of the desired derivation of PDU session to terminal device.

SMF network element can send PDU session expectation to terminal device during PDU session establishment or during modification Derivation QoS fuzzy rules, terminal device receive the desired derivation of PDU session from SMF network element QoS fuzzy rules.

Step S802, terminal device is believed according to the QoS fuzzy rules of the desired derivation of PDU session and the resource of terminal device Whether breath determines PDU session using reflection QoS.

Illustratively, terminal device predicts that it provides terminal device according to the QoS fuzzy rules of the desired derivation of PDU session Whether the influence in source determines PDU session using reflection QoS.The resource of terminal device includes the money of processing capacity and/or memory Source, if terminal device predicts the inadequate resource of its memory or processor ability with supporting reflex QoS, it is determined that PDU session Without using reflection QoS, if predicting that the resource of its memory or processor ability is enough supporting reflex QoS, it is determined that PDU session Use reflection QoS.

Step S803, terminal device instruction SMF network element terminal device supports PDU session to use reflection QoS.

When terminal device determines PDU using reflection QoS, step S803 is executed.Optionally, terminal device is to SMF network element The remaining QoS fuzzy rules derived from for indicating that information and/or terminal device can be supported are sent, which is used to indicate end End equipment supports PDU session to use reflection QoS.

Wherein, the processing capacity of terminal device and the resource of processor are certain, correspondingly, terminal device can be supported Derivation QoS rule quantity be also it is certain, terminal device can be determined according to the QoS fuzzy rules of stored derivation The remaining QoS fuzzy rules derived from that can be supported out.The remaining QoS derived from that SMF network element can be supported according to terminal device Fuzzy rules can determine not using reflection QoS using reflection QoS or to some service flows.

When terminal device determines PDU session without using reflection QoS, terminal device can not indicate to support to SMF network element PDU session uses reflection QoS.SMF network element is within a preset time if PDU is supported in the instruction for being not received by terminal device transmission Session then decides not to use reflection QoS using reflection QoS.

In the present embodiment, terminal device receives the QoS fuzzy rules of the desired derivation of PDU session from SMF network element, root According to the QoS fuzzy rules of the desired derivation of PDU session and the resource information of terminal device, determine PDU session whether using reflection QoS.It can cause terminal device that can not handle instead to avoid the inadequate resource of processing capacity or memory due to terminal device The problem of penetrating QoS.

Fig. 9 is the flow chart for the communication means that the embodiment of the present application seven provides, as shown in figure 9, side provided in this embodiment Method the following steps are included:

Step S901, UPF network element sends downlink data packet to terminal device, carries RQI in the downlink data packet.

Step S902, terminal device generates the QoS rule of derivation according to downlink data packet.

Terminal device determines the reflection QoS rule that derivation is then generated using reflection QoS according to the RQI that downlink data packet carries Then, and start derivation QoS rule reflection QoS timer.

Step S903, terminal device resets the reflection QoS timer of the QoS rule of derivation according to upstream data packet.

In the present embodiment, when terminal device has the transmission of upstream data packet, derivation is searched according to the QFI of upstream data packet QoS rule, resets the reflection QoS timer of the QoS rule of derivation.

In the prior art, terminal device can only reset the reflection QoS timing of the QoS rule of derivation according to downlink data packet Device.But if some QoS rule derived from does not have subsequent downlink data packet after generating, the QoS rule of the derivation Reflection QoS timer can expire quickly, and the QoS rule of the derivation can be deleted, at this point, if the QoS rule of the derivation is corresponding Business Stream there is upstream data packet to send, since the QoS rule of the derivation is deleted, terminal device can only lose uplink Data packet sends the upstream data packet using the QoS rule of default.

In the present embodiment, the reflection QoS timer for the QoS rule that terminal device is derived from according to the resetting of upstream data packet can The problem of being unable to satisfy qos requirement using the QoS rule of default to avoid upstream data packet packet loss or upstream data packet.

Step S904, upstream data packet is sent to UPF network element by terminal device.

Step S905, UPF network element is according to upstream data packet, resetting reflection QoS timer.

The reflection QoS timer of UPF network element resetting is the reflection QoS timer that terminal device is used to carry out QFI verifying. UPF network element can guarantee reflection QoS timer and the terminal on UPF by resetting reflection QoS timer according to upstream data packet The reflection QoS timer of the QoS rule of the derivation of equipment is consistent.

In the present embodiment, terminal device resets the reflection QoS timer of the QoS rule of derivation according to upstream data packet, will Upstream data packet is sent to UPF network element.It can be regular using the QoS of default to avoid upstream data packet packet loss or upstream data packet The problem of being unable to satisfy qos requirement.

It should be noted that the method for the present embodiment can be with above-described embodiment one to method either described in example IV It is used in combination, when terminal device receives downlink data packet, group can be reset using the method for embodiment one to example IV The reflection QoS timer of raw QoS rule, when terminal device generates upstream data packet, if upstream data packet is matched to this The QoS rule of derivation, then terminal device resets the reflection QoS timer of the QoS rule of the derivation.

The method of the present embodiment also can be used alone, i.e. for terminal device when receiving downlink data packet, use is existing Method resetting derive from QoS rule reflection QoS timer, when terminal device generation upstream data packet when, if upper line number The QoS rule of the derivation is matched to according to packet, then terminal device resets the reflection QoS timer of the QoS rule of the derivation.
