Description

A kind of resource selection method and device

Technical field

The present invention relates to mobile communication technology field more particularly to a kind of resource selection methods and device.

Background technique

Long evolving system (Long Term Evolution, LTE) is the next-generation mobile wireless access system of 3GPP, Including evolution block core net network equipment (Evolved Packet Core, EPC) and evolution base station (ENode B, ENB), EPC Equipment includes mobility management entity (Mobility Management Entity, MME), gateway (Serving Gateway, SGW) and the network elements such as packet data gateway (Packet Data Network Gateway, PGW), and EPC equipment Hardware platform control be based on advanced telecommunication computing structure (Advanced Telecom Computing Architecture, ATCA).

At present in LTE network, user terminal needs to carry out data transmission based on established carrying, therefore, user terminal Before carrying out practical business, it is necessary to complete registration process, i.e. attaching process in a network, only adhere to successful user terminal The IP address of distribution could be obtained, and default bearing is established based on allocated IP address.

Referring particularly to shown in Fig. 1, for the user terminal A for completing attachment that need to network, need to continue to use under ATCA framework The resource selection scheme used before attachment is established, need to undergo Flow Control Transmission Protocol (Stream to complete attachment Control Transmission Protocol, SCTP) access process, general packet radio service tunneling protocol for control plane (GTP-C) The transmission of (General Packet Radio Service Tunnelling Protocol-Control Plane, GTPC) message Process and carrying configuration flow.

In the SCTP access process of Fig. 1, the ENB where user terminal A is connected by interface with EPC equipment, and system can base The purpose services addresses of data are uploaded in user terminal A, route next jump selects interface processing unit, and is determining interface processing After unit, MME signaling processing entity is selected using load sharing mode by determining interface processing unit, completes first time resource Selection, wherein first resource selection includes the selection of interface and the selection of MME signaling processing entity.

After determining that the SCTP of user terminal A is successfully accessed, into GTPC message transmission flow, in GTPC message transmission flow In, MME signaling processing entity selection SGW signaling entity need to be completed, and PGW signaling entity process is selected by SGW signaling entity, Complete second of resource selection, wherein second of resource selection includes the selection of SGW signaling entity and the choosing of PGW signaling entity It selects.

Specifically, selecting SGW signaling entity for MME signaling processing entity, need to be randomly choosed by MME signaling processing entity Service processing entity carries out message forwarding, then selects SGW signaling entity by service processing entity；It is selected for SGW signaling entity PGW signaling entity process after determining SGW signaling entity, randomly chooses service processing entity by SGW signaling entity and carries out message turn Hair, then PGW signaling entity is selected by service processing entity,

After the completion of determining GTPC message transmission flow, into the carrying configuration flow of user terminal A, in carrying configuration flow In, service processing entity configuration carrying information need to be selected by PGW signaling entity, and business processing is selected by SGW signaling entity Entity configuration carries information, completes third time resource selection, wherein third time resource selection includes that PGW signaling entity selects industry Processing entities of being engaged in and SGW signaling entity select business processing.

After the completion of confirmation carrying configuration flow, the attaching process of user terminal A is completed.

However, in order to adapt to the demand of various product, it is often necessary to EPC equipment carry out dilatation, at present for, EPC is set There are the following two kinds modes for standby dilatation:

Mode one: adding corresponding processing function plate on the business processing machine frame of EPC equipment, referring particularly to Fig. 2 institute Show, relatively the business processing machine frame of original EPC equipment, increased in the business processing machine frame of the EPC equipment after dilatation signal command board A, Interface board, signal command board B and business board.

Specifically, signal command board A, signal command board B, business board and interface board are all with load sharing mode under ATCA framework Resource allocation is carried out, and interface board is individually disposed, and be provided out the interface of 8 to 12 out Incomings, wherein Incoming Data are forwarded to each signal command board by power board, on business board, that is, each operation flow is turned by power board Hair, for example, interface board sends datagram to signal command board, real process are as follows: data message is first sent to exchange by interface board Plate, then by power board by data message forwarding to signal command board.

In mode one, existing resource selection process will not impact substantially.

Mode two: by it is multiple have independent stacked at the EPC equipment of office, wherein EPC equipment can independently at Office, refers to that the EPC equipment can provide the interface of out Incoming, and dispose all signaling entities, service processing entity and interface Processing unit, referring particularly to shown in Fig. 3, former EPC equipment is made of an EPC equipment, dilatation EPC equipment by EPC equipment A extremely EPC equipment X composition.

Specifically, e.g., data message is shifted from the signaling entity of EPC equipment A for the data message for needing striding equipment to handle To the signaling entity of EPC equipment B, it need to be sent to the interface processing unit of EPC equipment A by the signaling entity of EPC equipment A, then by The interface processing unit of EPC equipment A is sent to the interface processing unit of EPC equipment B, is finally handled by the interface of EPC equipment B single Member is sent to the signaling entity of EPC equipment B.

However, in mode two, not only can influence overall transfer bandwidth because multiple striding equipment transmits, moreover, for across The situation of equipment processing, since the signaling entity of single EPC equipment is there are multiple, and existing resource selection process is step by step It carries out, therefore, process (e.g., SCTP access process and GTPC message transmission flow) is selected for different child resources, it may There are the inconsistent situations of resource selection.

For example, it is assumed that dilatation EPC equipment is made of EPC equipment 1 and EPC equipment 2, wherein the signaling of dilatation EPC equipment is real Body includes signaling entity A and signaling entity B, EPC equipment 1 includes signaling entity A1 and signaling entity B1, EPC equipment 2 includes letter Enabling entity A 2 and signaling entity B2, it is assumed that data message X need to be transferred to signaling entity B from the signaling entity A of dilatation EPC equipment, In existing resource selection process, if first time resource selection, the signaling entity A that selects for EPC equipment 1 signaling entity A1, then, for second of resource selection, it is more likely that the signaling entity A1 of EPC equipment 1 will not be selected, but EPC is selected to set Standby 2 signaling entity A2.

Obviously, if second of resource selection the result is that EPC equipment 2 signaling entity A2, then, resource selection result twice It is not have identity (not in same EPC equipment), later maintenance can be highly difficult.

As it can be seen that existing resource selection scheme is not particularly suited for all dilatation schemes, in view of this, being directed to EPC equipment The dilatation scheme of stacking in the embodiment of the present invention, provides a kind of new resource selection method, to overcome drawbacks described above.

Specific embodiment

In order to solve existing resource selection scheme applied in the dilatation of EPC equipment stacking, there are data message striding equipment biographies It is defeated, and the problem of cause transmission bandwidth to increase, in the embodiment of the present invention, a kind of resource selection method is redesigned, this method For firstly, an interface is selected from several interfaces corresponding with several EPC equipment, as to attached based on load sharing rule The corresponding target interface of message data of user terminal, then, be based on target interface, from several EPC equipment select one EPC equipment is as target EPC equipment, finally, the local signaling processing entity of target EPC equipment and local service are handled real Body is chosen to be the corresponding target signaling processing entity of user terminal to be attached and target service processing entities.

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, is not whole embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

The solution of the present invention will be described in detail by specific embodiment below, certainly, the present invention is not limited to Lower embodiment.

In the embodiment of the present invention, evolution block core net network equipment (Evolved Packet Core, EPC) equipment stacking Dilatation scene in Fig. 4, forms the core net after dilatation by two EPC equipment, each EPC equipment referring particularly to shown in Fig. 4 A corresponding interface, and be connected by interface with router, several user terminals pass through several evolution base station (ENode at place B, ENB), it is connected on router, and then by the corresponding interface, access in corresponding EPC equipment.

However, not all EPC equipment all has interface, and it is connected by interface with router, referring particularly to Fig. 5 Shown, router is connected to four EPC equipment by two interfaces, specifically, for there are the EPC equipment of interface, Ke Yitong Cross interface execute data out Incoming operation, and for be not present interface EPC equipment, can by with there are interfaces The association of EPC equipment executes the out Incoming operation of data.

Therefore, it in the embodiment of the present invention, is connect in several EPC equipment stacking dilatation scenes, all EPC equipment all exist Mouth and part EPC equipment provide different resource selection methods, wherein all EPC equipment there are two kinds of situations of interface respectively All there is interface to refer to, the number of EPC equipment is equal to the number of interface, and the corresponding EPC equipment of an interface, part EPC There are interfaces to refer to for equipment, and the number of EPC equipment is greater than the number of interface, and the corresponding EPC equipment of an interface.

As shown in fig.6, all there is the EPC equipment stacking dilatation of interface for all EPC equipment in the embodiment of the present invention Scene, the resource selection method process provided are as follows:

Step 600: based on load sharing rule, an interface is selected from several interfaces corresponding with several EPC equipment, The corresponding target interface of message data as user terminal to be attached.

Specifically, user terminal to be attached is to complete the attachment of the core net after dilatation, firstly, passing through place eNB Message data is sent to router, after router receives message data, resource management module can be advised based on load sharing Then, an interface, the corresponding target interface of message data as user terminal to be attached are selected from several interfaces, wherein So-called load sharing rule refers to, is based on load sharing principle, each EPC equipment is enabled uniformly to share corresponding load as far as possible.

For example, as shown in fig.7, " core net 1 " after dilatation is by " EPC equipment 1, EPC equipment 2 and EPC equipment 3 " group At, and each EPC equipment is individually at office, wherein " EPC equipment 1 " correspondence " interface 1 ", " EPC equipment 2 " correspondence " interface 2 ", " EPC equipment 3 " correspondence " interface 3 ", existing terminal M uploads message data by " eNB1 ", if at this time " EPC equipment 1 " " interface 1 " has accessed 30 user terminals, and " interface 2 " of " EPC equipment 2 " has accessed 34 user terminals, " EPC equipment 3 " " interface 3 " has accessed 25 user terminals, it is possible to the rule of the load sharing based on interface, accesses " interface 3 " for terminal M, That is, " interface 3 " is chosen to be target interface.

Step 610: being target EPC equipment by the corresponding EPC selection of equipment of target interface.

Specifically, all there is interface in all EPC equipment, and step 600 is negative based on interface by this present embodiment Lotus distribution rule carries out resource selection, thus, there is no being missed there are also EPC equipment, is based on this, resource management mould The corresponding EPC selection of equipment of target interface can be directly target EPC equipment by block.

For example, continue be illustrated with above-mentioned example, determine " interface 3 " be target interface after, can be directly right by " interface 3 " " the EPC equipment 3 " answered is chosen to be target EPC equipment.

Step 620: the local signaling processing entity of target EPC equipment is chosen to be the corresponding target of user terminal to be attached Signaling processing entity, and the local service processing entities of target EPC equipment are chosen to be the corresponding mesh of user terminal to be attached Mark service processing entity.

Specifically, the attaching process of control user terminal to be attached shown in FIG. 1, resource management module is user to be attached After the message data of terminal selectes interface, continue Flow Control Transmission Protocol (Stream Control Transmission Protocol, SCTP) mobility management entity (Mobility Management Entity, MME) in access process choosing It selects, in order to avoid the striding equipment of message transmits, therefore, by the local MME of target EPC equipment, is chosen to be user terminal to be attached The corresponding target MME in SCTP access process.

For example, continuing to be illustrated with above-mentioned example, due to having selected " interface 1 " Incoming, that is, have selected " EPC equipment 1 ", then " MME1 " of " EPC equipment 1 " is chosen to be the corresponding target MME of terminal M.

Further, if the SCTP access process success of terminal M, goes successively to general packet wireless service tunnel protocol Control plane (General Packet Radio Service Tunnelling Protocol-Control Plane, GTPC) disappears Cease transmission flow.

Since message data directly cannot be transmitted to gateway (Serving Gateway, SGW) by MME, but by industry Business processing entities are forwarded, and therefore, in order to avoid the striding equipment of message data transmits, need to be picked out by resource management module The service processing entity of message data forwarding is carried out, and receives the SGW of message data.

Therefore further, after resource management module selected target MME, the local service of target EPC equipment is handled real Body, is chosen to be user terminal to be attached corresponding target service processing entities in GTPC message transmission flow, and by target The local SGW of EPC equipment is chosen to be user terminal to be attached corresponding target SGW in GTPC message transmission flow.

For example, continue to be illustrated with above-mentioned example, after the SCTP access process success for determining terminal M, resource management mould Block selectes " the service processing entity 1-1 " of " EPC equipment 1 ", as target MME and mesh in the GTPC message transmission flow of terminal M The target service processing entities for executing distributed tasks between SGW are marked, and select " SGW1 " of " EPC equipment 1 " above-mentioned as receiving The target SGW of distributed tasks.

Similarly, due to message number between SGW and packet data gateway (Packet Data Network Gateway, PGW) According to transmission, need to be also forwarded by service processing entity.

Therefore further, the local service processing entities of target EPC equipment can be chosen to be target by resource management module Target service processing entities between SGW and target PGW, and by the local PGW of target EPC equipment, it is chosen to be user to be attached Terminal corresponding target PGW in GTPC message transmission flow.

For example, continuing to be illustrated with above-mentioned example, after the target SGW for selecting terminal M, resource management module selectes " EPC " the service processing entity 1-2 " of equipment 1 ", as being held between target SGW and target PGW in the GTPC message transmission flow of terminal M The target service processing entities of row distributed tasks, and select " PGW1 " of " EPC equipment 1 " as the mesh for receiving above-mentioned distributed tasks Mark PGW.

Further, after the GTPC message transmission flow success for determining user terminal to be attached, into carrying configuration stream Journey, whether PGW or SGW in the embodiment of the present invention, cannot directly execute configuration carrying task, but by business Reason entity is configured.

Therefore further, before target PGW and target SGW carry out carrying configuration information, resource management module is respectively Target PGW and target SGW selection target processing entities configuration carrying information, specifically, by the local service of target EPC equipment Entity is managed, user terminal to be attached corresponding target service processing entities in carrying configuration flow are chosen to be.

For example, continue to be illustrated with above-mentioned example, after determining the success of GTPC message transmission flow, resource management module choosing " the service processing entity 1-3 " for selecting " EPC equipment 1 " is that " PGW1 " carries out configuration carrying information, and selects " EPC equipment 1 " " service processing entity 1-4 " is that " SGW1 " carries out configuration carrying information.

As shown in fig.8, for part EPC equipment, there are the EPC equipment stacking dilatation fields of interface in the embodiment of the present invention Scape, the resource selection method process provided are as follows:

Step 800: based on load sharing rule, an interface is selected from several interfaces corresponding with several EPC equipment, The corresponding target interface of message data as user terminal to be attached.

For example, as shown in fig.9, " core net 2 " after dilatation is by " EPC equipment 1, EPC equipment 2, EPC equipment 3, EPC are set Standby 4 and EPC equipment 5 " forms, and each EPC equipment is individually at office, wherein " EPC equipment 1 " correspondence " interface 1 ", " EPC Equipment 2 " is corresponding " interface 2 ", and interface is not present in " EPC equipment 3 ", " EPC equipment 4 " and " EPC equipment 5 ", and existing terminal Y passes through " eNB4 " uploads message data, if " interface 1 " of " EPC equipment 1 " has accessed 67 user terminals at this time, " EPC equipment 2 " " interface 2 " has accessed 50 user terminals, it is possible to the rule of the load sharing based on interface, accesses " interface 2 " for terminal Y, That is, " interface 2 " is chosen to be target interface.

Step 810: the corresponding EPC equipment of target interface is determined as candidate EPC equipment, and is based on default weight rule, Select an EPC equipment as target EPC equipment from the associated several EPC equipment of candidate EPC equipment, wherein with candidate The associated several EPC equipment of EPC equipment include at least candidate's EPC equipment, and there is no all EPC equipment of interface.

Specifically, all there is interface in not all EPC equipment, and step 800 is to be based on connecing by this present embodiment Mouthful load sharing rule carry out resource selection, therefore, for there is no " the EPC equipment 3 " of interface, " EPC equipment 4 " and For " EPC equipment 5 ", is not selected, the wasting of resources is caused, moreover, will lead to all eNB in this way can all concentrate on In " EPC equipment 1 " and " EPC equipment 2 ", the load of " EPC equipment 1 " and " EPC equipment 2 " is increased.

Further, for the message data of user terminal to be attached, after through place, eNB is uploaded to router, only The core net after dilatation can be entered by interface by having, and specifically handled by which EPC equipment as subsequent, can also be based on target again Interface carries out resource selection again.

Specifically, firstly, the corresponding EPC equipment of target interface is determined as candidate EPC equipment, then, based on default power Weight-normality then, selects an EPC equipment as target EPC equipment from the associated several EPC equipment of candidate EPC equipment, wherein Candidate's EPC equipment is included at least with the associated several EPC equipment of candidate EPC equipment, and there is no all EPC of interface to set It is standby.

For example, with continued reference to shown in Fig. 9, for being uploaded to the message data of router, for " interface 1 " and " interface 2 ", there are two kinds of resources selection modes, if resource management module selection " interface 1 ", can determine that " EPC equipment 1 " is candidate EPC Equipment, and based on default weight rule, from " EPC equipment 1 ", " EPC equipment 3 ", " EPC equipment 4 " and " EPC equipment 5 ", select One EPC equipment is as target EPC equipment；If resource management module selects " interface 2 ", it can determine " EPC equipment 2 " for candidate EPC equipment, and based on default weight rule, from " EPC equipment 2 ", " EPC equipment 3 ", " EPC equipment 4 " and " EPC equipment 5 ", An EPC equipment is selected as target EPC equipment.

Further, firstly, determining the number with the associated several EPC equipment of candidate's EPC equipment, and if being based on number pair Dry EPC equipment is numbered, and determines weight radix based on number.

Then, it is determined that the IP address of the message data of user terminal to be attached, and XOR operation operation is executed to IP address, Exclusive or is obtained as a result, specifically, determine the IP address of the message data of user terminal to be attached, and IP address is segmented, Several sector addresses are obtained, successively step-by-step executes XOR operation operation to several sector addresses, obtains exclusive or result.

After obtaining exclusive or result, complementation operation is executed to fixed weight radix using exclusive or result, is joined The corresponding EPC equipment of the number for meeting parameter value is finally determined as target EPC equipment by numerical value.

For example, continuing to illustrate with example in step 800, " interface 2 " is target interface, therefore selected " EPC equipment 2 " is Candidate EPC equipment, due to " EPC equipment 2 " associated several EPC equipment include " EPC equipment 2 ", " EPC equipment 3 ", " EPC is set Standby 4 " and " EPC equipment 5 ", therefore ascertain the number as " 4 ", based on number 4 to " EPC equipment 2 ", " EPC equipment 3 ", " EPC equipment 4 " " EPC equipment 5 " is numbered respectively, and number result is " N0 ", " N1 ", " N2 ", " N3 ", and number " 4 " is determined as weight Radix " 4 "；

Further, it is assumed that the IP address of the message data of user terminal uploads to be attached is " 192.168.100.1 ", right It is segmented, and is obtained segmentation result " 192 ", " 168 ", " 100 " and " 1 ", is successively pressed to " 192 ", " 168 ", " 100 " and " 1 " Position executes XOR operation operation, as, " 11000000 " exclusive or " 10101000 " exclusive or " 01100100 " exclusive or " 00000001 ", Exclusive or result " 01101000 " is obtained, being converted to the decimal system is " 13 "；

Further, complementation operation is carried out to weight radix " 4 " with exclusive or result " 13 ", obtained parameter value " 1 ", by Include " 0,1,2,3 " in the remainder of " 13 " to " 4 ", it is corresponding with above-mentioned fixed number, determine the corresponding number of parameter value " 1 " For " N1 ", " N1 " corresponding EPC equipment is " EPC equipment 3 ", therefore, determine that " EPC equipment 3 " is target EPC equipment.

Certainly, resource management module is based on default weight rule, and respectively several user terminals to be attached carry out resource choosing When selecting, each EPC device numbering should be consistent.

Step 820: the local signaling processing entity of target EPC equipment is chosen to be the corresponding target of user terminal to be attached Signaling processing entity, and the local service processing entities of target EPC equipment are chosen to be the corresponding mesh of user terminal to be attached Mark service processing entity.

Specifically, as the embodiment that step 620 provides, in order to avoid the striding equipment of message transmits, resource management mould The local MME of target EPC equipment is chosen to be user terminal to be attached corresponding target MME in SCTP access process by block.

For example, continuing to be illustrated with above-mentioned example, having had selected " EPC equipment 3 " is target EPC equipment, then by " EPC " MME3 " of equipment 3 " is chosen to be the corresponding target MME of terminal Y.

If the SCTP access process success of terminal Y, goes successively to GTPC message transmission flow, since message data cannot SGW is directly transmitted to by MME, but is forwarded by service processing entity, therefore, in order to avoid the striding equipment of message data passes It is defeated, need to be picked out the target service processing entities for carrying out message data forwarding by resource management module, and receive message number According to target SGW.

For example, continue to be illustrated with above-mentioned example, after the SCTP access process success for determining terminal Y, resource management mould Block selectes " the service processing entity 3-1 " of " EPC equipment 3 ", as target MME and mesh in the GTPC message transmission flow of terminal Y The target service processing entities for executing distributed tasks between SGW are marked, and select " SGW3 " of " EPC equipment 3 " above-mentioned as receiving The target SGW of distributed tasks.

Similarly, it due to the transmission of message data between SGW and PGW, need to be also forwarded by service processing entity.

For example, continuing to be illustrated with above-mentioned example, after the target SGW for selecting terminal Y, resource management module selectes " EPC " the service processing entity 3-2 " of equipment 3 ", as being held between target SGW and target PGW in the GTPC message transmission flow of terminal Y The target service processing entities of row distributed tasks, and select " PGW3 " of " EPC equipment 3 " as the mesh for receiving above-mentioned distributed tasks Mark PGW.

For example, continue to be illustrated with above-mentioned example, after determining the success of GTPC message transmission flow, resource management module choosing " the service processing entity 3-3 " for selecting " EPC equipment 3 " is that " PGW3 " carries out configuration carrying information, and selects " EPC equipment 3 " " service processing entity 3-4 " is that " SGW3 " carries out configuration carrying information.
