For a better understanding of the present application, a resource allocation method of an exemplary embodiment of the present application is described below with reference to fig. 3.
Fig. 3 shows a flowchart of a resource allocation method according to an exemplary embodiment of the present application. As shown in fig. 3, the resource allocation method may include the following steps.

Wherein, in the resource reclamation transaction: ue denotes a terminal device, [ I ] ue ]Is a resource reclamation transaction T ue-SMF Represents the AMBR value in the transaction, which must come from the AMBR already obtained by the terminal equipment ue; [ o ═ AMBR → SMF]Is a transaction T ue-SMF And AMBR → SMF denotes that the terminal device gives the SMF the bit rate with the value of AMBR, and o denotes a procedure AMBR → SMF, i.e., a procedure of going from ue to SMF the bit rate with the value of AMBR. [ beforeeTS 1 ]Is a resource feedback transaction T ue-SMF The condition holds, separated from input and output by "|". TS (transport stream) 1 Is a point in time, and may be referred to as a resource recovery time, beforeTS, for example 1 Indicating when the transaction is at a point in time TS 1 Previously broadcast to the blockchain, the transaction can only be validated.
In a resource feedback transaction: [ o ]]For transaction T SMF-ue Input of [ AMBR → ue ]]AMBR value of (1) from T ue-SMF Output process of (o ═ AMBR → SMF)]，[afterTS 2 ]Is a transaction T SMF-ue The condition is true that identifies that the transaction must be broadcast to the blockchain after time point TS2 to be validated.
S302, the session management function entity broadcasts the set resource recovery transaction and resource feedback transaction in the network coverage area needing resource recovery.

S303, the terminal device modifies the transaction information contained in the broadcast message in response to the received broadcast message.
In this step, for example, the UE receiving the broadcast message 1 Modifying T ue-SMF Is T UE1-SMF {[I UE1 ]，[o＝ambr(SID 1 ，V 1 )+ambr(SID 2 ，V 2 )+…+ambr(SID n ，V n )→SMF]|[beforeTS 1 ]}, modify T SMF-ue Is T SMF-UE1 {[o]，[AMBR 1 →UE 1 ]|[afterTS 2 ]}。
Among them, ambr (SID) 1 ，V 1 ) Indicating session identification as SID 1 Has a session release value of V 1 AMBR of (2, AMBR, AMBR (SID) 1 ，V 1 )+ambr(SID 2 ，V 2 )+…+ambr(SID n ，V n ) → SMF denotes session identification as SID 1 、SID 2 、…、SID n N sessions of (1), each session releasing a value of V 1 、V 2 、…、V n The AMBR of (1).
In this step, the UE 1 Can be modified by modifying the transaction T ue-SMF And T SMF-ue UE in (1) is UE 1 And modifying AMBR to AMBR (SID) 1 ，V 1 )+ambr(SID 2 ，V 2 )+…+ambr(SID n ，V n ) And AMBR 1 Thereby setting the SMF as a transaction T ue-SMF And T SMF-ue And establishing an association relation with the self.
And S304, the terminal equipment sends the modified resource recovery transaction and the modified resource feedback transaction to the session management functional entity.
In this step, the UE 1 Will T UE1-SMF And T SMF-UE1 Sent to the SMF.
S305, the session management functional entity verifies the resource recovery transaction and the resource feedback transaction returned by the terminal equipment.
In this step, the SMF may perform the following verification step.
Verification condition 1: SMF verification T UE1-SMF V in 1 、V 2 、…、V n Whether or not to be less than or equal to UE 1 Session SID of 1 、SID 2 、…、SID n The current actual session-AMBR value. Verification condition 2: verification V 1 、V 2 、…、V n The sum meets the resource quantity requirement; verification condition 3: validating TS 2 Whether an acceptable time point is present; verification condition 4: verifying resource feedback requirement value AMBR 1 Whether or not it is less than or equal to V 1 、V 2 、…、V n And if the verification conditions are met, executing S306, otherwise ending the process.
In the verification condition 1, since there may be more than one UE sending out a transaction to the SMF for the AMBR in an actual application scenario, that is, the SMF may actually reclaim the AMBR from a plurality of different UEs, V in one UE 1 、V 2 、…、V n The sum of which may be less than or equal to the resource reclamation transaction T ue-SMF To satisfy a transaction requirement for the AMBR sent by the plurality of UEs to the SMF.
In verification condition 4, the resource feedback requirement value AMBR is verified 1 Less than or equal to V 1 、V 2 、…、V n In sum, the UE can be avoided 1 Smaller AMBRs are given and larger AMBRs are desirable as feedback. It should be noted that if the system rules allow the UE to execute 1 If a smaller AMBR is allowed and a larger AMBR is desired as a feedback, verify condition 4 may be eliminated.
In some embodiments, if SMF is at setting T ue-SMF And T SMF-ue The AMBR can be set in two transactions as a function of the resource demand value and the resource feedback supply value, for example: t is ue-SMF {[I ue ]，[o＝AMBR→SMF]|[beforeTS 1 ]}，T SMF-ue {[o]，[f(AMBR)→ue]|[afterts 2 ]Wherein the function f () is Y ═ 1.5 × X, X represents the resource demand value, and Y represents the resource feedback supply value of the SMF, i.e., T SMF-ue Wherein the AMBR value to be fed back to the at least one terminal device is T ue-SMF 1.5 times the value of AMBR recovered from at least one terminal device.
In some embodiments, if the verification conditions 1 to 4 are not all satisfied, the process may not be ended, but the SMF may initiate a back-and-forth negotiation, i.e., one or more negotiations, with the terminal device regarding the resource feedback requirement value and the resource feedback time for the terminal device to feed back.
That is, the SMF modifies and signs the resource recovery transaction and the resource feedback transaction, and then sends the modified and signed transactions to the terminal device. For example, SMF for T UE1-SMF And T SMF-UE1 After the content in the system is modified and signed, the content is sent to the UE 1 The modifications made may include, for example: modifying the resource feedback requirement value to ensure that the sum of the resource feedback requirement values of at least one terminal device is less than or equal to the resource feedback supply value; the modifications made may also include, for example: the resource feedback time is modified to an acceptable time point.
After receiving the resource recovery transaction modified and signed by the SMF and the resource feedback transaction modified and signed by the SMF, the terminal equipment signs and broadcasts to the block chain if the content modified by the SMF can be received; if the SMF cannot be modified, the transaction can be abandoned or the resource recovery transaction and the resource feedback transaction can be modified again to obtain new feedback information and send the new feedback information to the SMF.
And if the SMF verifies that the new feedback information meets the resource allocation condition, the negotiation is successful, and the SMF signs the resource recovery transaction and the corresponding resource feedback transaction corresponding to the successfully negotiated feedback information and then sends the signed transactions to the terminal equipment.
If the SMF verifies that the new feedback information still does not meet the resource allocation condition, the SMF can abandon the transaction with the terminal equipment, or modify and sign the resource recovery transaction and the resource feedback transaction again and then send the modified and signed transaction to the terminal equipment so as to repeat the negotiation process until the negotiation is successful or the SMF abandons the transaction with the terminal equipment.
And S306, the session management functional entity signs the resource recovery transaction and the resource feedback transaction returned by the terminal equipment and then sends the signed transaction to the terminal equipment.
In this step, SMF is coupled to T UE1-SMF And T SMF-UE1 Signature sending to UE 1 . Although SMF will sign T UE1-SMF And T SMF-UE1 Are all sent to the UE 1 But due to T SMF-UE1 Is from T UE1-SMF So if T UE1-SMF Is not broadcast to the blockchain, will result in T SMF-UE1 Input of [ o ]]Is a null value. So if the UE 1 Broadcasting only T SMF-UE1 Without broadcasting T UE1-SMF That is, only the extra AMBR is required to be reclaimed, but the extra AMBR is not required to be obtained by giving a peer AMBR in advance, thereby ensuring the normal progress of the resource reclamation transaction and the resource feedback transaction.
And S307, the terminal equipment adds the signature to the resource recovery transaction signed by the session management function entity and broadcasts the signature to the block chain.
In this step, the UE 1 For T UE1-SMF The additional signature is broadcast to the blockchain.
In one embodiment, transaction T is reclaimed in the resource ue-SMF The effective time length of temporary reclamation of AMBR can be agreed.
As an example, T ue-SMF {[I ue ]，[o＝(AMBR|3600)→SMF]|[before TS 1 ]And represents AMBR values before 3600 seconds of temporary recovery, i.e., 1 hour, and automatic recovery after more than 1 hour.
S308, after the resource feedback time, the terminal device adds a signature to the resource feedback transaction and broadcasts the signature to the blockchain.
In this step, at TS 2 After the moment, the terminal equipment is paired with T SMF-UE1 The additional signature is broadcast to the blockchain.
In one embodiment, the transaction T is a resource feedback transaction SMF-ue The effective time length of the temporarily fed-back AMBR can be agreed.
T SMF-ue {[o]，[(AMBR|3600)→ue]|[after ts 2 ]Denotes an arrival ts 2 The additional AMBR to be fed back has an expiration date of only 3600 seconds, i.e. 1 hour, and after more than 1 hour, the previous AMBR value is automatically restored.
Through the above steps S301-S308, a block chain intelligent contract may be used to make a temporary return of a portion of the credit of the AMBR that the subscriber has obtained to the mobile communication network between the subscriber and the mobile communication network, and after reaching the agreed time point, an increment of the AMBR equal to at least the previously traded credit may be obtained.
The following describes a specific flow of the resource allocation method performed by the mobile communication network, with reference to two specific examples. In an example one, the resource allocation method may include the following steps.
S401, the mobile communication network needs to allocate 5Mbps AMBR to a certain high-level user A, but the coverage area of RAN where the user A is located is only 4Mbps AMBR available.
S402, distributing SMF of AMBR for the user 1 Setting transaction T ue-SMF1 {[I ue ]，[o＝1Mbps→SMF 1 ]|[before“2020-06-0109:00:00”]} and T SMF1-ue {[o]，[1Mbps→ue]|[afterts 2 ]}。
In this embodiment, the user a may be a video conference started formally by joining a certain 9 o 'clock at 55 o' clock earlier by 1 st day 6/2020, and since the bandwidth resources are in short supply during this positive early peak period, the mobile communication network needs to temporarily recover part of the resources from the allocated AMBR.
S403，SMF 1 Will T ue-SMF1 And T SMF1-ue The broadcast is made within the coverage area of the RAN where user a is located.
S404, a certain user B sees the broadcast message and decides to make the UE-AMBR of the user B. Thus modifying T ue-SMF1 Is T IMSI1-SMF1 {[I IMSI1 ]，[o＝ambr(4837，900kbps)+ambr(9929，100kpbs)→SMF 1 ]|[before“2020-06-0109:00:00”]}, modify T SMF1-ue Is T SMF1-IMSI1 {[o]，[1Mbps→IMSI 1 ]|[after“2020-06-0118:30:00”]}。
As an example, user B may be watching a short video program (session ID 4837, occupying 900kbps of bandwidth), receiving SMF 1 After the broadcast message, consider that around 18 o' clock 30 a day, a subway will be taken and the time taken to take the subway will be used to watch the short video. Because the quality of wireless signals in the subway is not good usually, the AMBR in the period of 9 o 'clock earlier is selected to be replaced by the AMBR of 30 min 1Mbps in the later 18 o' clock.
Wherein, the user B chooses to give a right of 4837 session-AMBR, and marks that the user B stops watching the short video program; the 9929 session for user B, which may be, for example, an instant messaging session, chooses to have a session-AMBR of 100kbps indicating that user B would like to reduce the data rate of the session.
S405, the user B sends the T to the mobile phone IMSI1-SMF1 And T SMF1-IMSI1 Sent to the SMF.
In this step, the IMSI 1 An International Mobile Subscriber Identity (IMSI) indicating the terminal equipment of Subscriber b.
S406，SMF 1 Receiving T from user B IMSI1-SMF1 And T SMF1-IMSI1 After that, the following verification processing is performed: querying that session-AMBR values of 4837 and 9929 sessions of the user B are 900kbps and 250kbps respectively, wherein actual resource values corresponding to the two session identifiers both meet the requirement; the sum of 900kbps and 100kbps is exactly equal to 1Mbps, which meets the requirement; inquiring 2020-06-0118:30:00 to a Policy Control Function entity (PCF) to determine whether the requirement of a user B can be met or not, wherein PCF feedback can meet the requirement of the user B, and 1Mbps is just equal to the sum of 900kbps and 100 kbps; after passing the verification processing, the verification is judged to meet the requirements, and the next step is executed.
S407，SMF 1 For T IMSI1-SMF1 And T SMF1-IMSI1 The signature is sent to the user b.
S408, user second T IMSI1-SMF1 The additional signature is broadcast to the blockchain.
S409, the SMF closes the 4837 session of the user B according to the session, reduces the session-AMBR of the 9929 session to 150kbps, and reduces the UE-AMBR of the user B by 1 Mbps.
S410, after 18 o' clock and 30 minutes later, the mobile phone of the user B automatically sends T to the mobile phone of the user B SMF1-IMSI1 Broadcast to the blockchain.
S411, the mobile phone of the user B is carrying out the SMF of the session management to the current 2 Request additional 1Mbps UE-AMBR and prompt SMF 2 Transaction T SMF1-IMSI1 Already true.
In this step, the SMF2 and the SMF1 may be the same SMF or two different SMFs due to the movement of the terminal device of the user b. That is, the session management function entities for recovering resources and feeding back resources to the user b may be the same or different.
S412，SMF 2 Verifying a transaction T SMF1-IMSI1 Middle SMF 1 And the signature of the mobile phone of the user B, and 1Mbps of extra UE-AMBR is allocated to the user B.
In some scenarios, user B may only be able to obtain 500kbps of UE-AMBR for the 18 o' clock 30 period, but due to transaction T SMF1-IMSI1 It has been established that 1Mbps of AMBR can be additionally obtained, i.e., 1.5Mbps of UE-AMBR in total.
In practical application scenarios, if SMF 2 Also in the case where no extra resources are allocated to B, SMF 2 The same resource allocation method of the present embodiment as SMF1 may be employed to obtain additional resource allocation to b. And directly preempting the resources of other low-level users.
In some embodiments, the SMF may also directly determine whether the 18 th slot 30 is acceptable based on local policy, without having to query the PCF. This operation is also intended to avoid the occurrence of SMF 2 There are also situations in which there are insufficient resources to feed back to user b.
Through the above steps S401 to S412, in the case that there is a high-level user requesting resources in the mobile communication network, but there are no excess resources to meet the requirements of the high-level user, the mobile communication network may temporarily recover some AMBRs, and by setting the transaction of recovering the AMBRs and returning the recovered AMBRs to the transaction of the UE giving the AMBRs at a future point in time, a certain terminal UE determines that the currently actually used service traffic (for a period of time) is lower than the UE-AMBR obtained from the session management function entity, and may select to actively reduce its own UE-AMBR to reach the transaction with the mobile communication network. Therefore, a mode that part of UE-AMBRs obtain more UE-AMBRs at a certain future time point is adopted, reasonable allocation of resources is promoted, the utilization rate of network resources is improved, and service experience is enhanced.
In example two, the resource allocation method may include the following steps.
S501, the mobile communication network needs to allocate 5Mbps AMBR to a certain high-level user A, but the coverage area of RAN where the user A is located has only 4Mbps of available AMBR.
S502, distributing SMF of AMBR for the user 1 Setting transaction T ue-SMF1 {[I ue ]，[o＝1Mbps→SMF 1 ]|[before“2020-06-0109:00:00”]And T SMF1-ue {[o]，[1Mbps→ue]|[afterts 2 ]}。
S503，SMF 1 Will T ue-SMF1 And T SMF1-ue The broadcast is made within the coverage area of the RAN in which user a is located.
At S504, both user b and user c send the modified transaction to the SMF.
Wherein, the user B modifies T ue-SMF1 Is T IMSI1-SMF1 {[I IMSI1 ]，[o＝ambr(4837，900kbps)→SMF 1 ]|[before“2020-06-0109:00:00”]}, modify T SMF1-ue Is T SMF1-IMSI1 {[o]，[900kbps→IMSI 1 ]|[after“2020-06-0118:30:00”]}；
User C modifying T ue-SMF1 Is T IMSI2-SMF1 {[I IMSI2 ]，[o＝ambr(4700，200kbps)→SMF 1 ]|[before“2020-06-0109:00:00”]}, modify T SMF1-ue Is T SMF1-IMSI2 {[o]，[200kbps→IMSI 1 ]|[after“2020-06-0112:00:00”]}。
S505, users B and C respectively send T IMSI1-SMF1 And T SMF1-IMSI1 And T IMSI2-SMF1 And T SMF1-IMSI2 Sent to SMF 1 。
S506，SMF 1 It was found that although the AMBR values for both individual give-off transactions do not meet the overall requirements, the sum 1.1Mbps is greater than or equal to the predetermined 1Mbps requirement, and therefore there is a requirement for T IMSI1-SMF1 And T SMF1-IMSI1 And T IMSI2-SMF1 And T SMF1-IMSI2 And signatures are respectively sent to the user B and the user C.
S507, the user C will obtain an additional UE-AMBR of 200kbps when 12 o' clock later. User B will obtain an additional UE-AMBR of 900kbps after 18: 30.
Through the above steps S501 to S507, the mobile communication network may temporarily recover a plurality of user equipments AMBR, and set resource recovery transaction and resource feedback transaction for each user equipment, select to let the user equipment of the AMBR within the effective duration of the resource recovery transaction, and improve the utilization rate of network resources in the case that the actually used UE-AMBR is lower than the obtained UE-AMBR, and re-obtain the previously given AMBR credit at the time agreed with the mobile communication network, so as to enhance the service experience.
