Description

Maximum aggregation rate allocation method, device and system

Technical Field

The present application relates to the field of communications, and in particular, to a method, an apparatus, and a system for allocating Maximum aggregation Rate (AMBR).

Background

In a mobile communication network, an AMBR includes a concept of User Equipment (UE) -AMBR, i.e., a total maximum aggregate rate of all non-Guaranteed rate (GBR) traffic data streams of each UE. UE-AMBR is generally related to two factors: the service subscription relation of the UE in the mobile communication network and the dynamic service strategy of the mobile communication network. For example, the UE-AMBR may be calculated from session AMBRs (session-AMBRs) of all sessions currently active by the UE, and the calculated UE-AMBR is necessarily greater than or equal to the sum of the session AMBRs of all sessions in the active state.

At present, the AMBR already allocated to a UE may need to be recovered in some scenarios, for example, when the network available resources cannot meet the UE-AMBR of a certain UE, the allocation of the UE-AMBR cannot be implemented; as another example, although a certain UE obtains a higher UE-AMBR, it is not always able to fully utilize these bandwidth resources; as another example, a base station predicts that network congestion will occur. However, the related art does not give a solution.

It should be noted that, the first UE adds the second parameter in the first transaction, and adds the third parameter in the second transaction, so that the first transaction establishes an association relationship with itself.

In some example embodiments, the first UE may modify the AMBR1 in the first transaction to the session identity and corresponding yielded session AMBR value, and modify the UE to the identity of the first UE, i.e. the modified first transaction is:

T_UE1-SMF{[I_UE1]，[o＝ambr(SID₁，V₁)+ambr(SID₂，V₂)+…+ambr(SID_n，V_n)→SMF]}；

or, T_UE1-SMF{[I_UE1]，[o＝ambr(SID₁，V₁)+ambr(SID₂，V₂)+…+ambr(SID_n，V_n)|A→SMF]}；

In some exemplary embodiments, the second SMF entity may allocate the additional AMBR to the first UE by using a method known by those skilled in the art, or may allocate the additional AMBR to the first UE by using an AMBR management method proposed in this application, where the specific allocation method is not used to limit the scope of the embodiments of this application.

The detailed implementation process of the AMBR management method of the present application is described in detail below by two specific embodiments, which are listed only for convenience of description and cannot be considered as the only implementation manner of the AMBR management method of the present application.

Example 1

This embodiment describes discovering that the available AMBR of the network is smaller than the AMBR that needs to be allocated to user a when allocating the AMBR to user a, and negotiating with user b to reach a first transaction and a second transaction, so that user b gives itself a portion of the AMBR to allocate to user a, and allocates additional AMBR to user b as feedback.

For example, the user a may have joined a video conference that is going to be formally started, and the mobile communication network needs to temporarily reclaim a part of the resources from the allocated AMBR due to the shortage of bandwidth resources at this time.

The method comprises the following steps:

(1) the mobile communication network needs to allocate 5Mbps of AMBR to a certain high-grade user a, but there is only 4Mbps of AMBR available in the first coverage area where the user a is located. That is, the available AMBR in the first coverage area where user a is located is smaller than the AMBR that needs to be allocated for user a.

(2) The SMF1 setting transaction T for allocating AMBR to the user A_UE-SMF1{[I_UE]，[o＝1Mbps→SMF1]And T_SMF1-UE{[o]，[1Mbps→UE]|[map(c，p)，RAN(sub(c))in-chain]}。

(3) SMF1 broadcasts a first transaction T in a first coverage area where user A is located_UE-SMF1And a second transaction T_SMF1-UE。

(4) And a certain user B receives the first transaction and the second transaction and decides to give the AMBR of the user B. Thus modifying T_UE-SMF1Is T_IMSI1-SMF1{[I_IMsI1]，[o＝ambr(4837，900kbps)+ambr(9929，100kpbs)→SMF1]}, modify T_SMF1-UEIs T_SMF1-IMSI1{[o]，[1Mbps→I_MSI1][ map (c) ' Beijing City great Xin district Beijing east road No. 1 '), RAN (sub) (c) ' in-chain]}。

For example, user b may be watching a short video program (session id 4837, occupying 900kbps of bandwidth), and upon receiving the first and second transactions of SMF1, consider the need to share network links between multiple devices at home via a cell phone hotspot after returning to home daily. Then choose to let the current AMBR get back to the home with an additional 1Mbps AMBR.

User b gives the all session AMBR for the session identified as 4837 indicating that user b stopped watching the short video program.

The 9929 session of user B, which may be an instant messaging session, elects to let the 100kbps session AMBR, indicate that user B would like to reduce the data rate of the session.

IMSI1 is the IMSI of user b's handset.

(5) User B sends a first transaction T to a first SMF entity_IMSI1-SMF1And a second transaction T_SMF1-IMSI1。

(6)SMF1 receives T from user B_IMSI1-SMF1And T_SMF1-IMSI1And then:

1. the address "beijing municipality beijing dongdong 1" is mapped to coverage area set C, C ═ 4600656850001, 4600656850002, 4600656850003.

2. Neither user a nor user b is currently located in the area of C, i.e. not any of 4600656850001, 4600656850002, 4600656850003. And (5) passing the verification.

3. And inquiring the PCF whether the coverage area set C can meet the requirement of the user B, namely whether the first UE can be allocated with the additional AMBR of the second value as feedback, wherein the PCF feedback can meet the requirement of the user B. And (5) passing the verification.

The SMF can also directly determine whether the area identified by C can meet the requirement of the user b according to the local policy without inquiring the PCF.

4. The current actual session AMBR values for the two sessions for which user b is queried for session identification 4837 and 9929 are 900kbps and 250kbps, respectively. All meet the requirements.

5. The sum of the two session-giving AMBR values (i.e., 900kbps and 100kbps) for session identifications 4837 and 9929 is exactly equal to 1 Mbps. Meets the requirements.

6. The AMBR value to be traded is less than or equal to the sum of said first values for all said first UEs (i.e. 1Mbps is exactly equal to the sum of 900kbps and 100 kbps). Meets the requirements.

7. The above steps are all in accordance with the requirements, and the next step is executed.

(7) SMF1 converting T_SMF-UE1Modified as T_SMF1-UEIs T_SMF1-IMSI1{[o]，[1Mbps→I_MSI1]| [ map ({4600656850001, 4600656850002, 4600656850003}, "Beijing City of great district Beijing east road No. 1"), RAN (sub ({4600656850001, 4600656850002, 4600656850003})) in-chain]}；

(8) SMF1 vs. T_IMSI1-SMF1And T_SMF1-_IMSI1Signature, T that will carry SMF1 signature_IMSI1-SMF1And T_SMF1-IMSI1And sending the data to a user B.

(9) User second T_IMSI1-SMF1Adding user B signature, and carrying T of SMF1 signature and user B signature_IMSI1-SMF1Broadcast to the blockchain.

(10) The SMF accordingly closes the session identified as 4837 for user b, reduces the session AMBR for the session identified as 9929 to 150kbps (i.e., by 100kbps), and reduces the AMBR for user b by 1 Mbps.

(11) When user b enters any one of areas 4600656850001, 4600656850002, 4600656850003, an area identifier with a base station signature is received from the base station, for example 4600656850003 with the base station signature is received. And {4600656850003} is a subset of {4600656850001, 4600656850002, 4600656850003 }.

(12) And the mobile phone of the user B broadcasts the mobile phone of the user B to the block chain, wherein 4600656850003 with the base station signature is added with the user B signature, and 4600656850003 with the base station signature and the user B signature is broadcasted. Whereby T_SMF1-IMSI1The established first transaction condition is satisfied.

(13) User B is requesting an additional 1Mbps AMBR from SMF2 currently conducting session management and prompting SMF2 to trade T_SMF1-IMSI1Already true.

SMF2 may be the same SMF as SMF1 or two different SMFs.

(14) SMF2 verifies transaction T_SMF1-IMSI1SMF1 signature and user B signature, and transaction T_SMF1-IMSI1The first transaction condition holds, and then an additional 1Mbps AMBR is allocated to user b.

In practice, if SMF2 is also in a situation where no additional resources are allocated to b,

a) SMF2 may use the same approach as SMF1 to obtain additional resource allocation to b.

b) And directly preempting the resources of other low-level users.

User B may normally only be able to obtain 500kbps of UE-AMBR at home, but due to the second transaction T_SMF1-IMSI1It has been established that 1Mbps of AMBR can be additionally obtained, i.e., 1.5Mbps of UE-AMBR is totaled

Due to {4600656850001, 4600656850002, 4600656850003 is calculated from SMF1 according to "No. 1 of northeast road of great Xingdistrict of Beijing City", and SMF2 and SMF1 belong to the same mobile communication network, therefore T is_SMF1-IMSI1The first condition to be fulfilled must be verified.

Example 2

This embodiment describes discovering that the network's available AMBR is less than the AMBR that needs to be allocated to user a when allocating AMBR to user a, and by negotiating with user b and user c to reach a first transaction and a second transaction, allowing user b and user c to allocate their own portion of AMBR to user a, and allocating additional AMBR to user b and user c as feedback.

(4) User b and user c both sent a first transaction and a second transaction to SMF1, where:

a) user B modifies T_UE-SMF1Is T_IMSI1-SMF1{[I_IMSI1]，[o＝ambr(4837，900kbps)→SMF1]}, modify T_SMF1-UEIs T_SMF1-IMSI1{[o]，[900kbps→IMSI1][ map (c) ' Beijing City great Xin district Beijing east road No. 1 '), RAN (sub) (c) ' in-chain]}；

b) User C modifies T_UE-SMF1Is T_IMSI2-SMF1{[I_IMSI2]，[o＝ambr(4700，200kbps)→SMF1]}, modify T_SMF1-UEIs T_SMF1-IMSI2{[o]，[200kbps→IMSI1][ map (c) '10 # financial street in Western City of Beijing City ], RAN (sub) (c)' in-chain]}；

(5) User B general T_IMSI1-SMF1And T_SMF1-IMSI1Sent to SMF1, user C sends T_IMSI2-SMF1And T_SMF1-IMSI2To SMF 1.

(6) SMF1 found that although neither of the AMBR values for the two individual give-off transactions met the overall requirement, the sum 1.1Mbps is greater than or equal to the predetermined 1Mbps requirement, and therefore T is assigned_IMSI1-SMF1Modified as T_IMSI1-SMF1{[I_IMsI1]，[o＝ambr(4837，900kbps)→SMF1]Get T out of_SMF1-IMSI1Modified as T_SMF1-IMSI1{[o]，[900kbps→IMSI1]| [ map {4600656850001, 4600656850002, 4600656850003}, "Beijing City of Daxing district Beijing east road No. 1"), RAN (sub ({4600656850001, 4600656850002, 4600656850003})) in-chain]And will T_IMSI2-SMF1Modified as T_IMSI2-SMF1{[I_IMSI2]，[o＝ambr(4700，200kbps)→SMF1]}, modify T_SMF1-IMSI2Is T_SMF1-IMSI2{[o]，[200kbps→IMSI1][ map ({4600601107733}, "financial avenue 10. in the western city, Beijing), ] RAN (sub ({4600601107733})) in-chain]}. Then to T_IMSI1-SMF1And T_SMF1-IMSI1Adding SMF1 signature to send to user B, and sending T_IMSI2-SMF1And T_SMF1-IMSI2The SMF1 signature is added and sent to user c.

(7) User B will obtain an additional AMBR of 900kbps after arriving at Dow 1 of great district, Beijing. User C will obtain an additional AMBR of 200kbps after arriving at financial street number 10 in the Western City of Beijing.
