Specific embodiment

It is understandable to enable the above objects, features and advantages of the present invention to become apparent from, it is below in conjunction with the accompanying drawings and concrete real The present invention is further detailed explanation to apply mode.

In order that those skilled in the art further appreciate that the embodiment of the present invention, bearing resource is realized to current LTE below The scheme of release is illustrated.

ENB be carried on access or renewal process in can obtain interface-free resources, it is if now interface-free resources are not enough, right Priority is relatively low, and the resource of the carrying that can be preempted is seized, and the resource of the carrying being preempted will be released, specifically Process is referred to a kind of process schematic of bearing resource release of the prior art shown in Fig. 1, is presented as on S1 interfaces E-RAB RELEASE (RAB release) process, MME is according to E-RAB RELEASE INDICATION (wireless access Carry release and indicate message) in the corresponding core-network sides of E-RAB that indicate of radio bearer resources list E-RAB list carry, to SGW sends RELEASE ACCESS BEARERS REQUEST (carrying right to use releasing request message), request release S1 interfaces Carrying, if SGW agree to discharge the carrying, return RELEASE ACCESS BEARERS RESPONS (carry the right to use release Put response message).

However, the following problem of problem that the scheme of the bearing resource release is present：

1, ENB sends E-RAB RELEASE to MME while release local carrying, by each EPC network element processing difference With the impact of time delay, the release of the carrying in EPC network elements relatively lags behind, and now the descending business datum in part can still be sent to In the carrying of release, cause user data loss, produce business datum and retransmit.

2, carry under release conditions in ENB, descending business datum still reaches the carrying of the ENB, causes S1 interfaces ERR INDICATION (miscue message) are generated, into failure flow process is carried, is runed counter to program design original meaning itself.

As current release flow process may cause the transfer rate of UE to decline, serious conditions may cause user's application connection Interrupt, simultaneously because the reason such as part EPC network elements release delay and service surface caching, causes UE partial services data to retransmit, plus The pressure that acute ENB eats dishes without rice or wine.

Exactly inventor herein has found the seriousness of this problem, creatively proposes the core structure of the embodiment of the present invention One of think of is that, when the carrying that power is seized with higher resource is accessed, using other carryings, temporarily replacement is preempted resource Carry forwarding service data, it is to avoid business data transmission is interrupted, improve Consumer's Experience effect.

With reference to Fig. 2, the step of carry the embodiment of the method for business data processing when seizing in showing a kind of LTE of the invention Flow chart, the Long Term Evolution LTE include to include first user in the evolution base station ENB with evolution base station ENB First carrying of equipment UE 1, described first carries and can specifically may be used including the first allocation retention priority ARP1, described method To comprise the steps：

Step 101, when the second carrying of the new second user equipment UE 2 for accessing evolution base station ENB, its second distribution retains When priority ARP2 is higher than first allocation retention priority ARP1, evolution base station ENB inquiry is with the presence or absence of described the 3rd carrying of one user equipment (UE) 1；If having the 3rd to carry, execution step 102；

In EPS, the basic granularity that QoS (Quality of Service, service quality) is controlled is to carry, i.e., identical to hold All business datums in load will obtain identical QoS and ensure (such as scheduling strategy, buffering queue management, link layer configuration etc.), Different QoS is ensured to be needed different types of carrying to provide.In implementing, according to the difference of QoS, carrying can be divided For two big class：GBR (Guranteed Bit Rate, it is ensured that bit rate) is carried and Non-GBR (Non-Guranteed Bit Rate, non-ensured bit rate) carry.GBR refers to the bit rate of bearing requirements by the constant distribution of network " permanent ", even if In the case of Internet resources anxiety, corresponding bit rate can also keep.MBR (Maximum Bit Rate) parameter is defined Under conditions of GBR is carried on resource abundance, the upper limit of the service data transmission rate that can be reached.The value of MBR is possible to be more than Or equal to the value of GBR.Contrary, Non-GBR is referred in the case of network congestion, and carrying to need to bear reduces wanting for speed Ask, fixed Internet resources need not be taken as Non-GBR is carried, thus can be set up for a long time.And GBR carries general Simply just set up when needed.

In embodiments of the present invention, if the resource of second carrying of the new UE2 for accessing is seized power and held higher than the first of UE1 Carry, i.e., the second ARP for carrying (Allocation/Retention Priority, distribution keep priority), higher than in ENB First carries, then second carry the resource that will seize the first carrying, and first carries and will be released, and now ENB will inquire about this Ground is carried with the presence or absence of the 3rd, wherein, the described 3rd carries and can carry for non-ensured bit rate non-GBR.

Specifically, ENB inquiry be preempted carry belonging to UE under with the presence or absence of except be preempted carry in addition to non-GBR, such as Fruit is not present, then can directly discharge the carrying and its Radio Resource being preempted, illustrate now to illustrate that the carrying being preempted is UE1 The last item default bearing.After the carrying is preempted, all bearer contexts of the UE1 in ENB can be deleted, now ENB will not provide business data transmission service for UE1.

Step 102, the evolution base station ENB carry transmission services data to the first user equipment using the described 3rd UE1；The business datum is sent to described first by evolution block core net EPC and is carried, and the EPC is mutually communicated with the LTE Letter；

In embodiments of the present invention, if there is other carryings in ENB, such as non-GBR then can arbitrarily choose which In a descending carrying that continues as UE1 business datums, form descending succession relation, i.e. industry with first carrying to be released Business data downstream direction is every to be sent to the 3rd carrying to be released, by the 3rd carry by business datum transfer to it is selected under This partial data is sent to UE1, and shared UE-AMBR by the Radio Resource of the descending carrying that continues by the capable carrying that continues, ENB.

In one preferred embodiment of the invention, described method can also comprise the steps：

The evolution base station ENB starts preemption delay intervalometer.

Wherein, when release is preempted the Radio Resource of carrying, can start and seize delay timer T, need explanation It is to seize delay timer T to be restricted this according to network design situation flexible configuration, the embodiment of the present invention.

Step 103, the evolution base station ENB judge that described second carries whether the time accessed exceedes the default time； If described second carries the time accessed more than Preset Time, the step 104 is performed；

In one preferred embodiment of the invention, the sub-step of the step 103 can be：

When the time default more than the preemption delay intervalometer, the evolution base station ENB judges that described second carries The time of access exceedes the default time.

In a kind of preferred exemplary of the present invention, after start delay intervalometer T exceedes its default time, ENB can be with Judge that the time that the second carrying is accessed exceedes the default time.

Step 104, the evolution base station ENB stop carrying the transmission business datum to first user using the described 3rd Equipment UE 1, and discharge first carrying.

In one preferred embodiment of the invention, the step 104 can include following sub-step：

Sub-step S11, the evolution base station ENB stop carrying the transmission business datum to the first use using the described 3rd Family equipment UE 1；

Sub-step S12, the evolution base station ENB are deleted described first and carry corresponding contextual information.

In embodiments of the present invention, when second carries the time accessed more than the default time, it is believed that in EPC network elements First carrying related resource be released, will not again to first carry send business datum, now ENB can discharge Treat the resource of the first carrying.It is erased entirely to the now first related context for carrying, in addition, the 3rd carries this in LTE Up-downgoing succession relation in network remains unchanged.

In order that those skilled in the art better understood when the embodiment of the present invention, below by way of a specific example The embodiment of the present invention is illustrated：

A kind of bearing resource of the present invention with reference to shown in Fig. 3 be preempted before business data flow direction schematic diagram, wherein, UE It is air wireless interface (UU interfaces) between ENB, is S1U interfaces between ENB and SGW, is S5 interfaces between SGW and PGW, It is SGI interfaces between PGW and APN (Access Point Name, access network title).In actual applications, UE is carried on A Downlink service data, by PGW and SGW network element of APN (Access Point Name, the access network title) network by network side Carrying relaying after be sent to the carrying A of ENB, business datum is sent to UE by the interface-free resources of carrying A by ENB again.

A kind of bearing resource of the present invention with reference to shown in Fig. 4 be preempted after business data flow direction schematic diagram, when in ENB After the resource of carrying A is preempted, choose non-GBR and B is carried as the carrying that continues of the downlink service data for carrying A, then carry A Downlink data flow direction be changed to：Still by carrying A to ENB transmission services data in PGW and SGW, now UE is in carrying B UU interfaces on still can receive from the business datum for carrying A, but the business datum of A is carried in the ENB by holding Data are sent to UE by the Radio Resource for carrying B.When seize delay timer T it is overtime after, that is, more than seizing delay timer T The EPC sides network element estimated discharges the time of carrying A related contexts to be released, can be with the contextual information of deleting bearing A.Seize The time of back off timer T was could be arranged to more than EPC deenergized periods.Certainly, preemption delay intervalometer T can be according to different Network design situation flexible configuration.

It should be noted that described in such scheme being, except the UE is in addition to carrying to be released (carry of A), still exist The scene that non-GBR is carried, should be divided into following two situations in practice：

1st, carrying to be released (carrying A) is not the default bearing under UE certain PDN, and the UE still has which under the PDN His default bearing.After A releases are carried, the downlink service data on A is carried in EPS by by carrying the silent of the PDN belonging to A Recognize carrying transmission, i.e., after A releases are carried, the default bearing (for example carrying B) in EPS temporarily alternative bearer A will continue to pass Defeated business datum；

2nd, the UE has multiple APN connections, and carries the default bearing that A is PDN under certain APN.But under others APN Still there is default bearing in PDN connections.After A releases are carried, the downlink service data carried on A will be refused on SGI interfaces Absolutely, business datum stops transmission.

For situation 1, the embodiment of the present invention ensure that the data for carrying A are not interrupted during being preempted.For feelings Condition 2, the embodiment of the present invention do not affect the characteristic that business data transmission stops.

Carry in existing ENB and seize under scene, specific algorithm is not quite similar when being realized due to each manufacturer, causes different EPC There is larger difference in the release time that network element is carried, thus possible caused business datum disconnection, and the speed experience to user is made Into considerable influence.Secondly, in the process, the continuous transmission of data, the ERR of possible initiating system due to the release that carries INDICATION flow processs, so as to affect the KPI (Key Performance Indicator, critical sales index) of grid. And apply the embodiment of the present invention, it can be ensured that be carried on be preempted be carried on release during business datum service the guarantor that continues Hold.Specifically, before the carrying that ENB releases are preempted, if the UE has non-GBR carryings, from current ENB Non-GBR chooses a descending carrying that continues as carrying to be released in carrying, and generates the short-term of the local carryings to be released of ENB Descending succession relation, the business datum of carrying to be released can be sent to by selected non-GBR carryings in handoff procedure UE, guarantee are preempted the ability of the business continuous transmission of carrying.Wherein, the time that the handoff procedure succession relation keeps can be by One Timer Controlling, starts intervalometer when seizing beginning, after the timer expiry, can delete succession relation, and thoroughly Deletion is preempted the contextual information of carrying.

It should be noted that for embodiment of the method, in order to be briefly described, therefore which to be all expressed as a series of action group Close, but those skilled in the art should know, the application is not limited by described sequence of movement, because according to this Shen Please, some steps can adopt other orders or while carry out.Secondly, those skilled in the art should also know, description Described in embodiment belong to preferred embodiment, necessary to involved action not necessarily the application.
