Description

Maximum aggregation rate distribution method, device and system

Technical Field

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

Background

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

Currently, in some scenarios, AMBR already allocated to UE may need to be reclaimed, for example, when the network available resources cannot meet the UE-AMBR of a certain UE, allocation of the UE-AMBR cannot be achieved; as another example, although a UE obtains a higher UE-AMBR, these bandwidth resources are not always fully utilized; as another example, a certain base station predicts that network congestion will occur. However, the related art does not give a solution.

In the present application, different trigger conditions may be set for different application scenarios to trigger negotiation with at least one first UE to reach the first transaction.

For example, the mobile communication network needs to allocate AMBR of 5 megabits per second (Mbps, million bits per second) to a certain high-level user a (i.e., the second UE), but the available AMBR in the first coverage area where the user a is located is 4Mbps, at this time, the first SMF entity corresponding to the user a needs to broadcast the first transaction invitation in the first coverage area to request other UEs to let out a part of the AMBR of itself, so as to allocate AMBR to the user a.

Then, the trigger condition may be set as: the available AMBR in the first coverage area where the second UE is located is smaller than the AMBR that needs to be allocated for the second UE.

In some example embodiments, the first coverage area in which the second UE is located may be: the sector in which the second UE is currently located, or the tracking area in which the second UE is currently located, or the routing area in which the second UE is currently located, etc.

In the present application, negotiating with at least one first UE to reach a second transaction means that each of N first UEs reach a second transaction; wherein N is an integer greater than or equal to 1.

In some example embodiments, negotiating with at least one first UE to reach a first transaction and a second transaction comprises:

In some exemplary embodiments, the determining that the first transaction condition is met based on the first parameter, the second parameter, the third parameter, and the set of coverage areas includes:

In some example embodiments, the policy control function (PCF, policy Control Function) entity may be queried for acquisition in determining whether a coverage area in the set of coverage areas is capable of allocating additional AMBRs of the second value for the first UE as feedback.

In some example embodiments, the identity of the first UE may be any information that identifies the identity of the first UE in the network. For example, an international mobile subscriber identity (IMSI, international Mobile Subscriber Identity) may be used.

In some exemplary embodiments, the first transaction is in the form of: t (T) _UE-SMF {[I _UE ]，[o＝AMBR1→SMF]}；

Wherein T is _UE-SMF Representing a transaction of the UE to the first SMF entity;

[I _UE ]for the first transaction T _UE-SMF An AMBR value indicating that a transaction is required must come from an AMBR value that the UE has obtained;

[o＝AMBR→SMF]for the first transaction T _UE-SMF Ambr1→smf represents that AMBR with the value AMBR1 is handed to SMF, o represents that the process ambr1→smf is represented by o. AMBR1 is the AMBR value that needs to be traded.

In some exemplary embodiments, the first transaction further carries: a first effective length of time.

In some exemplary embodiments, the first transaction carrying the first effective length of time is in the form of: t (T) _UE-SMF {[I _UE ]，[o＝AMBR 1|A→SMF]}；

Wherein A is a first effective time length.

In the present application, receiving the first transaction carrying the second parameter and the second transaction carrying the third parameter sent by the at least one first UE means that one first transaction carrying the second parameter and one second transaction carrying the third parameter are received from each of the N first UEs, respectively.

In some exemplary embodiments, the first UE receives the first transaction and the second transaction carrying the first parameter, and in case it is determined to let itself AMBR, may add the third parameter to the second transaction by adding the second parameter to the first transaction, and then return the first transaction carrying the second parameter and the second transaction carrying the third parameter to the first SMF entity. It should be noted that, the first UE adds the second parameter to the first transaction, and adds the third parameter to the second transaction, so that the first transaction and the first UE establish an association relationship.

In some exemplary embodiments, the first UE may modify AMBR1 in the first transaction to a session identifier and a corresponding let-off session AMBR value, and modify the UE to the identifier of the first UE, that is, the modified first transaction is:

T _UE1-SMF {[I _UE1 ]，[o＝ambr(SID ₁ ，V ₁ )+ambr(SID ₂ ，V ₂ )+…+ambr(SID _n ，V _n )→SMF]}；

alternatively T _UE1-SMF {[I _UE1 ]，[o＝ambr(SID ₁ ，V ₁ )+ambr(SID ₂ ，V ₂ )+…+ambr(SID _n ，V _n )|A→SMF]}；

Wherein UE1 represents the identity of the first UE, ambr (SID ₁ ，V ₁ ) Representing session identification as SID ₁ AMBR reduction V for a session of (a) ₁ ，SID ₁ Session identification, V, representing session 1 ₁ A session AMBR value indicating the 1 st session let, AMBR (SID ₂ ，V ₂ ) Representing session identification as SID ₂ AMBR reduction V for a session of (a) ₂ ，SID ₂ Session identification, V, representing session 2 ₂ Session AMBR value, … …, AMBR (SID _n ，V _n ) Representing session identification as SID _n AMBR reduction V for a session of (a) _n ，SID _n Session identification representing nth session, V _n A session AMBR value indicating the let-off of the nth session.

In this application, it should be noted that although the first SMF entity will sign T _UE1-SMF And T _SMF - _UE1 Are all sent to the first UE, but due to T _SMF-UE1 The input of (2) is from T _UE1-SMF Thus T _UE1-SMF Not broadcast to the blockchain will result in T _SMF-UE1 Input o of (i)]Is a null value. So if the first UE only broadcasts T _SMF-UE1 Without broadcasting T _UE1-SMF (i.e., want to acquire additional AMBR only, but not want to let peer AMBR in advance), also cannot acquire additional AMBR.

In some exemplary embodiments, the second transaction also carries: a second effective length of time.

In some exemplary embodiments, the second transaction is in the form of:

T _SMF-UE {[o]，[AMBR1→UE]|[map(c，p)，RAN(sub(c))in-chain]-a }; alternatively T _SMF-UE {[o]，[AMBR1|B→UE]|[map(c，p)，RAN(sub(c))in-chain]}；

[map(c，p)，RAN(sub(c))in-chain]Is the second transaction T _SMF-UE The conditions that are established, i.e., the first transaction conditions, are separated from the input and output by "|". Wherein:

c is a set of sectors, may include 1 sector or a plurality of sectors, and the plurality of sectors may not belong to the same base station. It should be noted that, here, the sector is the coverage area described above;

p is a geographic location or geographic range, described by longitude and latitude or by literal address

map (c, p) means that the transaction can only be validated if the set of sectors identified by c matches the geographic location identified by p;

sub (c) represents a subset of the set of sectors identified by c;

RAN (sub (c)) means that the base station signs sub (c);

RAN (sub) in-chain means sub (c) with base station signature is broadcast to the blockchain;

b is a second effective length of time.

In some exemplary embodiments, the first UE may modify p in the second transaction to be the location information for which additional AMBR is desired to be obtained as feedback, modify the UE to the identity of the first UE, i.e., the modified first transaction is:

T _SMF-UE1 {[o]，[AMBR1→UE1]|[map(c，P)，RAN(sub(c))in-chain]-a }; alternatively T _SMF-UE1 {[o]，[AMBR1|B→UE1]|[map(c，P)，RAN(sub(c))in-chain]}；

Wherein P is the position information that the first UE expects to obtain additional AMBR as feedback.

Step 101, for each first UE, reducing the AMBR of the first UE by a corresponding first value.

In some example embodiments, reducing the AMBR of the first UE by a corresponding first value includes:

In the application, under the condition that the current actual session AMBR value of the session is equal to the yielding AMBR value, directly closing the session;

In the case that the current actual session AMBR value of the session is greater than the let-off AMBR value, the session AMBR of the session is reduced by the let-off session AMBR value corresponding to the session identifier without closing the session.

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

The following details the implementation of the AMBR management method of the present application by two specific embodiments, where the listed embodiments are merely for convenience of illustration, and the listed embodiments are not to be construed as the only implementation of the AMBR management method of the present application.

Example 1

The embodiment describes that when AMBR is allocated to user a, the available AMBR of the network is found to be smaller than the AMBR which needs to be allocated to user a, the first transaction and the second transaction are achieved by negotiating with user b, so that user b allocates part of AMBR of itself to user a, and additional AMBR is allocated to user b as feedback.

For example, user a may have joined a video conference that is about to begin formally, and the mobile communication network may need to temporarily reclaim some 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 AMBR of 5Mbps to a certain high-level user a, but only 4Mbps of AMBR is 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 less than the AMBR that needs to be allocated to user a.

(2) Setting transaction T for SMF1 of AMBR allocated to user A _UE-SMF1 {[I _UE ]，[o＝1Mbps→SMF1]Sum T _SMF1-UE {[o]，[1Mbps→UE]|[map(c，p)，RAN(sub(c))in-chain]}。

(3) SMF1 will broadcast the first transaction T in the first coverage area where user a is located _UE-SMF1 And a second transaction T _SMF1-UE 。

(4) And a user B receives the first transaction and the second transaction and decides to let the user B self AMBR. Thus modify T _UE-SMF1 Is T _IMSI1-SMF1 {[I _IMsI1 ]，[o＝ambr(4837，900kbps)+ambr(9929，100kpbs)→SMF1]' modify T _SMF1-UE Is T _SMF1-IMSI1 {[o]，[1Mbps→I _MSI1 ][ map (c, "Beijing Daxing area North Ring Donglu No. 1"), RAN (sub (c)) in-chain]}。

For example, user b may be watching a short video program (session id 4837, 900kbps occupied) and, after receiving the first and second transactions of SMF1, consider the need to share a network link between multiple devices at home via a cell phone hotspot after daily return to home. Then select the AMBR that lets the current AMBR, the extra 1Mbps after the replacement home.

All session AMBR lets out for the session identified as 4837 by user b, indicating that user b stops watching the short video program.

User b's 9929 session, which may be an instant messaging session, selects the 100kbps session AMBR indicating a willingness to reduce the data rate of the session.

IMSI1 is the IMSI of the user b's mobile phone.

(5) User B sends a first transaction T to a first SMF entity _IMSI1-SMF1 And a second transaction T _SMF1-IMSI1 。

(6) SMF1 receives T from user B _IMSI1-SMF1 And T _SMF1-IMSI1 Thereafter:

1. the address "Beijing Daxing area North Ring Donglu 1" is mapped to the coverage area set C, C= {4600656850001, 4600656850002, 4600656850003}.

2. Neither user a nor user b is currently in the range of C, i.e., neither of 4600656850001, 4600656850002, 4600656850003. Verification passes.

3. And querying the PCF whether the requirement of the user B can be met in the coverage area set C, namely whether the additional AMBR of the second value can be distributed for the first UE as feedback, and the PCF feedback can meet the requirement of the user B. Verification passes.

The SMF may also directly determine, according to the local policy, whether the region identified by C may meet the requirements of user b, without having to query the PCF.

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

5. The sum of AMBR values (i.e., 900kbps and 100 kbps) yielded by two sessions identified as 4837 and 9929 is exactly equal to 1Mbps. Meets the requirements.

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

7. The above all meet the requirements, and the next step is executed.

(7) SMF1 will T _SMF-UE1 Modified to be T _SMF1-UE Is T _SMF1-IMSI1 {[o]，[1Mbps→I _MSI1 ]Map ({ 4600656850001, 4600656850002, 4600656850003}, "Beijing city, daxing area, north Ring Dong Lu 1"), RAN (sub ({ 4600656850001, 4600656850002, 4600656850003 })) in-chain]}；

(8) SMF1 vs T _IMSI1-SMF1 And T _SMF1 - _IMSI1 Signature, T to carry SMF1 signature _IMSI1-SMF1 And T _SMF1-IMSI1 And sending the message to the user B.

(9) User B T _IMSI1-SMF1 Adding user B signature, and carrying SMF1 signature and T of user B signature _IMSI1-SMF1 Broadcast to the blockchain.

(10) The SMF accordingly closes the session of user B with session identification 4837, reduces the session AMBR of the session identified as 9929 to 150kbps (i.e., reduces 100 kbps), and reduces the user B's AMBR by 1Mbps.

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

(12) After the mobile phone of the user B adds the user B signature to the 4600656850003 with the base station signature, 4600656850003 carrying the base station signature and the user B signature is broadcasted to the blockchain. Whereby T is _SMF1-IMSI1 The established first transaction condition is satisfied.

(13) User B is requesting additional AMBR of 1Mbps from SMF2 currently performing session management and prompting SMF2 transaction T _SMF1-IMSI1 This has been established.

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

(14) SMF2 authentication transaction T _SMF1-IMSI1 SMF1 signature and user B signature, and transaction T _SMF1-IMSI1 The first transaction condition established then assigns an additional AMBR of 1Mbps to user b.

In practice, if SMF2 is also in the case 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) Other low-level users' resources can also be preempted directly.

User B may only obtain a UE-AMBR of 500kbps at home at ordinary times, but due to the second transaction T _SMF1-IMSI1 It has been established that 1Mbps of AMBR can be additionally obtained, i.e. 1.5Mbps in total of UE-AMBR

Since {4600656850001, 4600656850002, 4600656850003} is calculated by SMF1 according to "Beijing Daxing area North Ring Dong Lu 1", and SMF2 and SMF1 belong to the same mobile communication network, T is _SMF1-IMSI1 The first condition that is established must be satisfied.

Example 2

This embodiment describes that when allocating AMBR to user a, the available AMBR of the network is found to be smaller than the AMBR that needs to be allocated to user a, and the first transaction and the second transaction are achieved by negotiating with user b and user c, so that user b and user c allocate part of their AMBR to user a, and allocate additional AMBR to user b and user c as feedback.

(4) Both user b and user c sent a first transaction and a second transaction to SMF1, wherein:

a) User B modification T _UE-SMF1 Is T _IMSI1-SMF1 {[I _IMSI1 ]，[o＝ambr(4837，900kbps)→SMF1]' modify T _SMF1-UE Is T _SMF1-IMSI1 {[o]，[900kbps→IMSI1][ map (c, "Beijing Daxing area North Ring Donglu No. 1"), RAN (sub (c)) in-chain]}；

b) User C modification T _UE-SMF1 Is T _IMSI2-SMF1 {[I _IMSI2 ]，[o＝ambr(4700，200kbps)→SMF1]' modify T _SMF1-UE Is T _SMF1-IMSI2 {[o]，[200kbps→IMSI1]Map (c, "Beijing city and western urban financial street 10"), RAN (sub (c)) in-chain]}；

(5) User B will T _IMSI1-SMF1 And T _SMF1-IMSI1 To SMF1, user C will T _IMSI2-SMF1 And T _SMF1-IMSI2 To SMF1.

(6) SMF1 found that although neither of the two single let-off transactions had an AMBR valueMeets the overall requirement, but adds up to 1.1Mbps to the predetermined 1Mbps requirement, thus T will be _IMSI1-SMF1 Modified to be T _IMSI1-SMF1 {[I _IMsI1 ]，[o＝ambr(4837，900kbps)→SMF1]}, T is _SMF1-IMSI1 Modified to be T _SMF1-IMSI1 {[o]，[900kbps→IMSI1]Map {4600656850001, 4600656850002, 4600656850003}, "Beijing Daxing area North Cycloeast No. 1"), RAN (sub ({ 4600656850001, 4600656850002, 4600656850003 })) in-chain]And T is to _IMSI2-SMF1 Modified to be T _IMSI2-SMF1 {[I _IMSI2 ]，[o＝ambr(4700，200kbps)→SMF1]' modify T _SMF1-IMSI2 Is T _SMF1-IMSI2 {[o]，[200kbps→IMSI1]Map ({ 4600601107733}, "Beijing city, western urban finance street 10"), RAN (sub ({ 4600601107733 })) in-chain]}. Then to T _IMSI1-SMF1 And T _SMF1-IMSI1 Adding SMF1 signature to send to user B, and T _IMSI2-SMF1 And T _SMF1-IMSI2 And adding the SMF1 signature to send to the user C.

(7) Subscriber b will obtain an additional AMBR of 900kbps upon reaching north cycloeast No. 1 of the region of daxing, beijing, city. User C will obtain an additional AMBR of 200kbps after reaching financial street number 10 in the western urban area of Beijing city.
