Abstract
The invention discloses a method of determining calling priority in an eMLPP business realization process. The method includes: in calling establishment process, compare the priority level of calling and called user eMLPP; if the called user eMLPP is higher than the calling user, re-determine the calling priority according to the called user eMLPP priority and revise the calling priority to the re-determined priority. The application of the invention can improve the fairness of eMLPP business realization.
Description
Technical field
The present invention relates to strengthen multipriority and seize (eMLPP:enhanced Multi-LevelPrecedence and Pre-emption) service technique, particularly a kind of method of in the implementation procedure of eMLPP business, determining call priority.
Background technology
Along with mobile subscriber's rapid increase, the capacity problem of cordless communication network has become the problem of operator's overriding concern.In the conversation peak period of every day,, will cause occurring network congestion because cordless communication network is difficult to satisfy communication request that concentrate, a large amount of; In the city center, hot zones also tends to exist serious network congestion, these proper communications that all influenced the user to a certain extent insert.If when network congestion takes place, take same strategy queuing to insert to all users, be obviously unfair then to high-end user, therefore urgent day by day to the demand of user's classification.
Third generation partner program (3GPP) has proposed the eMLPP business at this demand.EMLPP is a kind of supplementary service of global system for mobile communications (GSM)/universal mobile telecommunications system (UMTS) network, and it is divided into 7 ranks with the user, i.e. priority level A, B, 0,1,2,3 and 4 (priority level from high to low).Wherein, priority level A, B are network level, only are used for mobile switching centre (MSC) inside, and the user can not subscribe to this two kinds of priority; Priority level 0～4 is a user class, can subscribe to for the user.When network congestion, the eMLPP business will preferentially guarantee the proper communication of high-priority users.
Before the implementation procedure of introducing existing eMLPP business, earlier other two kinds of priority that may relate in the eMLPP business realizing process are briefly introduced:
1) distribution/maintenance priority (Allocation/Retention Priority): different Allocation/Retention priority correspondences different resource race to control indications, is seized indication and queuing indication, when carrying out allocation of radio resources, this priority is used in reference to the wire guide network and distributes corresponding radio resource for the user; When network congestion, this priority is used for carrying out between the user seizing and lining up of Radio Resource.Therefore, when relating to wireless resource allocation, seize and lining up, what call priority referred to is exactly this priority.
2) multipriority and seize (MLPP) priority: be used between MSC, distinguishing call priority, that is: when needs transmit precedence information between caller network and called network, use MLPP priority.
There are certain mapping relations between this priority of three types of eMLPP priority, Allocation/Retention priority and MLPP priority, different phase at call setup may need to use dissimilar priority as the priority of calling out, corresponding mapping relations are followed in conversion between the dissimilar priority, and described conversion is carried out in network.
According to 3GPP technical standard TS22.067, TS23.067 and TS24.067, the implementation procedure that has the eMLPP business now is introduced below.Fig. 1 is the call setup schematic flow sheet of existing eMLPP business.Referring to Fig. 1, this call setup flow process comprises:
Step 101: calling subscriber equipment (UE) is determined calling subscriber's eMLPP priority.
The priority (comprising greatest priority and default priority) that the eMLPP service-user is subscribed to is stored in user's the SIM card and HLR.In this step, the calling subscriber can call out for this in calling UE and select eMLPP priority, verify by the visit SIM card whether the selected eMLPP priority of calling subscriber is effective by calling UE then: if effectively, determine that then this priority is calling subscriber's eMLPP priority, otherwise, be to be lower than and near the effective priority of the selected priority of calling subscriber with calling subscriber's eMLPP priority level initializing.
If in this step, the calling subscriber does not select priority, and then in step 102, the caller network is set to the acquiescence eMLPP priority that the calling subscriber subscribes to calling subscriber's eMLPP priority.
Step 102:, between calling UE and caller network, carry out the Calling Side call establishment according to calling subscriber's eMLPP priority.
Described Calling Side call establishment, comprise: carry out Calling Side connection management (CM), eMLPP priority to calling subscriber and calling subscriber is carried out authentication, authentication and encryption, carry out Calling Side call setup (Setup), carry out the Calling Side allocation of radio resources and set up Calling Side radio bearer (RB).
Wherein, in the process of carrying out the Calling Side allocation of radio resources, at first determine corresponding Allocation/Retention priority, carry out wireless resource allocation according to Allocation/Retention priority then, and set up corresponding radio bearer according to calling subscriber's eMLPP priority.Under the situation of network congestion, described allocation of radio resources process will be referred to carry out seizing and lining up of Radio Resource according to the Allocation/Retention priority of calling out.
In gsm system, the caller network comprises: calling UE base station sub-system of living in (BSS) and MSC, and called network comprises: called UE BSS of living in and MSC;
In the UMTS system, the caller network comprises: calling UE RNS of living in (RNS) and MSC, called network comprises: called UE RNS of living in and MSC.
Step 103: the caller network makes a call to called UE place called network by initial address message (IAM), carries the MLPP priority corresponding with calling subscriber eMLPP priority among the IAM.
Step 104: the MLPP priority of carrying among the IAM as priority parameters, is carried out the callee side call establishment between called UE and called network.
Described callee side call establishment comprises: the paging called UE, the called subscriber is carried out authentication, authentication and encryption, and carry out callee side CM, carry out callee side Setup, carry out the callee side allocation of radio resources and set up the callee side radio bearer.
Wherein, in callee side Setup process, called network with the MLPP priority of carrying among the IAM as priority parameters, at first determine calling subscriber's eMLPP priority according to this MLPP priority, eMLPP priority with the calling subscriber sends to called UE then, is used for the called UE decision this is called out whether carry out automatic-answering back device or called seizing;
In the process of carrying out allocation of radio resources, called network with the MLPP priority of carrying among the IAM as priority parameters, at first determine corresponding Allocation/Retention priority according to MLPP priority, carry out wireless resource allocation according to Allocation/Retention priority then, and set up corresponding radio bearer.Under the situation of network congestion, described allocation of radio resources process will be referred to carry out seizing and lining up of Radio Resource according to the Allocation/Retention priority of calling out.
Step 105: called network sends Address Complete Message (ACM) to the caller network.
Step 106: behind the called subscriber answer, called network sends response message (ANS) to the caller network.
Step 107: calling subscriber and called subscriber converse.
So far, finish the call setup handling process of existing eMLPP business.
In the call flows shown in Figure 1, suppose that calling UE and called UE are in the different MS C coverage.If calling UE and called UE are in the same MSC coverage, illustrate that MSC and the MSC in the called network in the caller network are same MSC, then need not to send described IAM message, ACM message and ANS message between caller network and the called network, and, in the process of carrying out the described callee side call setup of step 104, with directly with calling subscriber's eMLPP priority as priority parameters.
By the call setup flow process of above-mentioned existing eMLPP business as seen, the priority of calling is by calling subscriber's eMLPP priority decision, and is irrelevant with called subscriber's eMLPP priority.When high eMLPP priority users receives calling from low eMLPP priority users, this calling is low in the priority level of whole network, so under the situation of network congestion, this calling is seized probably, therefore high eMLPP priority users just can't be enjoyed the treatment of high priority when called, as seen, determine in the existing eMLPP business realizing process that the method for call priority lacks fairness.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method of definite call priority, reaches the purpose of the fairness that improves the eMLPP business realizing.
For achieving the above object, technical scheme of the present invention specifically is achieved in that

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
The eMLPP priority that main thought of the present invention is based on the called subscriber promotes end-to-end call priority, thereby the eMLPP priority of taking into account calling subscriber and called subscriber in the implementation procedure of eMLPP business is determined the priority of calling, thereby improves the fairness of eMLPP business realizing.
Fig. 2 determines the schematic flow sheet of the method for call priority in the implementation procedure of eMLPP business for the present invention.Referring to Fig. 2, this method is carried out following operation in call establishment:
Step 201: relatively calling subscriber and called subscriber's eMLPP priority just if called subscriber's eMLPP priority is higher than calling subscriber's eMLPP priority, then continues execution in step 202, otherwise, the method ends flow process;
Step 202: the priority that redefines described calling according to called subscriber's eMLPP priority;
Step 203: with the priority modification of described calling is the described priority that redefines.
So far, finish the method flow that the present invention determines call priority.
In actual applications, calling subscriber and called subscriber may be in different MS C coverage, also may be in same MSC coverage; Corresponding to both of these case, the main body of carrying out each operation in the such scheme of the present invention is also with difference.
First kind of situation: when calling subscriber and called subscriber are in different MS C coverage, according to background technology as can be known, the caller network will send to called network with the MLPP priority of calling subscriber eMLPP priority correspondence by IAM message, and, called subscriber MSC of living in can get access to called subscriber's eMLPP priority more easily, therefore, preferably, the operation of described relatively calling subscriber of step 201 and called subscriber's eMLPP priority height, and the described operation that redefines call priority of step 202, can carry out by called subscriber MSC of living in; And step 203 described be the operation of the priority that redefines with the priority modification of calling out owing to relate to caller network and called network, can carry out by calling subscriber MSC of living in and called subscriber MSC of living in respectively.
Second kind of situation: when calling subscriber and called subscriber are in same MSC coverage, according to background technology as can be known, described MSC will be known selected eMLPP priority when the calling subscriber makes a call, and can get access to called subscriber's eMLPP priority more easily, therefore, preferably, the operation of described relatively calling subscriber of step 201 and called subscriber's eMLPP priority height, the described operation that redefines call priority of step 202, and step 203 described be the operation of the priority that redefines with the priority modification of calling out, all can carry out by this MSC.
Fig. 3 shows the schematic flow sheet of the method that the present invention is directed to above-mentioned first kind of definite call priority that situation provided.Among Fig. 3, with the step shown in the fillet square frame is to introduce the step of the required increase of technical solution of the present invention on prior art scheme basis, is that technical solution of the present invention need be to having the step that corresponding steps is made amendment now with the step shown in dashed rectangle and the dotted arrow.Referring to Fig. 3:
In step 301～step 303, carry out and step 101 shown in Figure 1～step 103 identical operations.
In step 304, called subscriber MSC of living in preserves the MLPP priority of carrying in the IAM message, and obtain called subscriber's eMLPP priority, the eMLPP priority height that compares calling subscriber and called subscriber then:, then continue execution in step 305 if calling subscriber's eMLPP priority is lower than called subscriber's eMLPP priority; Otherwise, carry out subsequent treatment according to prior art, that is: carry out the operation of step 104 shown in Figure 1～step 107, the method ends flow process.
In this step, can be according to the mapping relations of MLPP priority and eMLPP priority, the height of MLPP priority of carrying in the comparison IAM message and called subscriber's eMLPP, thereby definite calling subscriber and called subscriber's eMLPP priority height.
In this step, can obtain maximum eMLPP priority, acquiescence eMLPP priority that the called subscriber subscribes to or the effective eMLPP priority that sets in advance eMLPP priority from called subscriber's VLR Visitor Location Register (VLR) as the called subscriber.Certainly, also can be from other equipment, for example: be specifically designed to the eMLPP priority of obtaining the called subscriber in the equipment of storage eMLPP priority.
In step 305, redefine the priority of this calling according to called subscriber's eMLPP priority.
In this step, the mode that redefines the priority of this calling according to called subscriber's eMLPP priority can have following several:
1) called subscriber's who is directly obtained with step 304 eMLPP priority is as the priority of described calling;
2) according to the weight coefficient that sets in advance, the called subscriber's that calling subscriber's eMLPP priority and step 304 are obtained eMLPP priority is weighted, and weighted results is defined as the priority of described calling.
In step 306, as priority parameters, carry out the callee side call establishment with the priority that redefines.
The performed operation of operation that this step is performed and step 104 shown in Figure 1 is identical, difference only is: in the step 104 with the MLPP priority of carrying among the IAM as priority parameters, that is: with the MLPP priority of calling subscriber eMLPP priority correspondence as priority parameters; And in this step with the priority that redefines as priority parameters, that is: with the call priority determined according to called subscriber eMLPP priority as priority parameters.
In step 307, called network sends ACM message to the caller network, and carries the call priority that redefines in ACM message.
In actual applications, called network also can carry the call priority that redefines by the described ANS message of step 308 or other message that set in advance, as long as can make the caller network know the described call priority that redefines.
In step 308, the caller network judges in the ACM message come from called network and carries precedence information that then the priority modification with this calling is a priority entrained in the ACM message, promptly is revised as the priority that redefines.
The described modification of this step is exactly: subscriber call BSS of living in or RNS, the Allocation/Retention priority of this calling is made amendment, and it is revised as the rank corresponding with the priority that redefines.Like this, when network congestion takes place, will carry out seizing and lining up of Radio Resource according to described amended Allocation/Retention priority.
In step 309, behind the called subscriber answer, called network sends ANS message to the caller network.
In step 310, calling subscriber and called subscriber converse.
So far, finish to determine in the described preferred embodiment of Fig. 3 the method flow of call priority.
Above in conjunction with Fig. 3, calling subscriber and called subscriber are under the different MS C coverage situation, the embodiment of the method for definite call priority provided by the present invention has been described in detail.The implementation procedure that is in calling subscriber and called subscriber under the situation of same MSC coverage is roughly the same, difference is: need not forwarding step 303,307 and 309 described message, and, step 304,305,306 and 308 described operations are carried out by described MSC, please refer to flow implementation shown in Figure 3, do not repeat them here.
As seen from the above technical solution, the method for determining call priority in eMLPP business realizing process disclosed in this invention provides a kind of solution that promotes end-to-end call priority based on called subscriber's eMLPP priority.When this scheme is lower than called subscriber's eMLPP priority in calling subscriber's eMLPP priority, at first redefine the priority of this calling according to called subscriber's eMLPP priority, priority modification with this calling is this priority that redefines then, that is: by priority lifting be and the corresponding high priority of called subscriber eMLPP priority with this calling, reach the purpose that in the implementation procedure of eMLPP business, embodies called subscriber's fairness, thereby realized improving the fairness of eMLPP business realizing.
As previously mentioned, the eMLPP business is a kind of supplementary service of GSM/UMTS network, according to 3GPP technical standard TS22.067, TS23.067 and TS24.067, the realization flow of eMLPP business in the GSM network and realization flow basically identical in the UMTS network, difference only are that employed message follows GSM relevant criterion and UMTS relevant criterion respectively.Below in conjunction with existing correlation technique standard and accompanying drawing the call flows of implementing the inventive method in the UMTS network is elaborated.
Fig. 4 and Fig. 5 are respectively Calling Side call flow schematic diagram and the callee side call flow schematic diagrames of implementing the inventive method in the UMTS network.Referring to Fig. 4 and Fig. 5:
UE1 and UE2 represent calling UE and called UE respectively;
RNS1 and RNS2 represent calling subscriber RNS of living in and called subscriber RNS of living in respectively;
MSC1 and MSC2 represent calling subscriber MSC of living in and called subscriber MSC of living in respectively;
VLR1 and VLR2 represent calling subscriber's VLR and called subscriber's VLR respectively;
HLR1 and HLR2 represent calling subscriber's attaching position register (HLR) and called subscriber's HLR respectively;
AuC1 and AuC2 represent Calling Side AUC (AuC) and callee side AuC respectively;
The step that marks with X1～X6 among Fig. 4 and Fig. 5 is to introduce the step of the required increase of technical solution of the present invention on prior art scheme basis, will specifically note in follow-up explanation for the step that needs are revised.Now, referring to Fig. 4:
In performed being operating as of step 1～step 19: the eMLPP priority according to the calling subscriber is the call distribution Radio Resource and the resource of landing between from UE1 to MSC2, particularly:
In step 1, between UE1 and RNS1, set up radio resource control (RRC) and be connected.
In step 2, UE1 sends connection management service request (CM Service Request) message to RNS1, carries the eMLPP priority that the calling subscriber selects in this request message.
In step 3, RNS1 sends initial UE message (Initial UE Message) to MSC1, and the eMLPP priority that the calling subscriber is selected sends to MSC1.
In step 4～5, MSC1 carries out authentication by visit VLR1 to the eMLPP priority that the calling subscriber selects, and simultaneously, network side is finished calling subscriber's identification and encryption.
In step 6, VLR1 returns the request of access to MSC1 and accepts (Access Request Accepted) message.
In step 7～8, MSC1 returns the connection management service by RNS1 to UE1 and accepts (CMService Accepted) message.If the calling subscriber does not select eMLPP priority, then in this step, MSC1 need obtain the acquiescence eMLPP priority that the calling subscriber subscribes to from VLR1, and the priority that will call out is made as described acquiescence eMLPP priority.
In step 9～11, UE1 initiates the Setup process to network side, and called subscriber's mobile subscriber ISDN number (MSISDN) is sent to MSC1.
In step 11～12, MSC1 registers in VLR1 with this and calls out relevant information.
In step 13～14, MSC1 sends (CallProceeding) message in the call treatment by RNS1 to UE1, comprises the eMLPP priority of the calling subscriber after MSC1 determines in this message, and UE1 preserves this priority.
In step 15～17, MSC1 sends wireless access load-bearing allocation request (RABAssignment Request) message to RNS1, comprises the Allocation/Retention priority corresponding with calling subscriber's eMLPP priority in the message; RNS1 is this call distribution corresponding radio resource according to this priority, and returns the RAB assignment to MSC1 and finish message (RAB Assignment Complete).Under the situation of network congestion, this allocation of radio resources process will be referred to carry out seizing and lining up of Radio Resource according to Allocation/Retention priority.
In step 18～19, MSC1 is according to called subscriber's MSISDN, obtains the routing iinformation of UE2 by visit HLR2, and sends initial address message (IAM) to the MSC2 at UE2 place.Carry the MLPP priority corresponding in this IAM message with calling subscriber eMLPP priority.
Now, referring to Fig. 5:
At step X1, after MSC2 receives IAM message, preserve the MLPP priority of carrying in this IAM message.
In step 20～24, MSC2 initiates paging (Paging) message to UE2; RNS2 sets up RRC with UE2 and is connected; UE2 responds beep-page message (Paging Response) to MSC2.
In step 25, MSC2 sends the request (Processing AccessREQ) in the processing that inserts to VLR2.
At step X2, the eMLPP priority that VLR2 inquiry UE2 subscribes to.
In step 26, called network carries out authentication, identification and encryption to UE2.
In step 27, VLR2 returns the request of access to MSC2 and accepts message (Access RequestAccepted), carries the eMLPP priority that the called subscriber subscribes in this message.As previously mentioned, this eMLPP priority can be called subscriber's maximum eMLPP priority of subscribing to, acquiescence eMLPP priority or effective eMLPP priority of setting in advance.
At step X3, relatively calling subscriber and called subscriber's eMLPP priority just, and when calling subscriber eMLPP priority is lower than called subscriber eMLPP priority, redefine the priority of this calling according to called subscriber's eMLPP priority, and in follow-up callee side call establishment, with this priority that redefines as priority parameters.About how redefining the priority of this calling, please refer to explanation about flow process shown in Figure 3, do not repeat them here.
As previously mentioned,, then need not to promote the priority of this calling, can finish the subsequent voice calls handling process according to prior art if calling subscriber eMLPP priority is higher than called subscriber eMLPP priority.The relevant description of present embodiment subsequent step all is to be lower than this situation of called subscriber eMLPP priority at calling subscriber eMLPP priority.
In step 28～29, MSC2 sends connection management CM service by RNS2 to UE2 and accepts message (CM Service Accept).
In step 30～33, MSC2 sends Setup message to UE2, comprises the call priority that redefines in the message, is used for the UE2 decision whether this calling is carried out automatic-answering back device or called seizing.
In step 34, MSC2 sends wireless access load-bearing allocation request (RAB AssignmentRequest) message to RNS2, comprises the Allocation/Retention priority corresponding with the call priority that redefines in the message.
In step 35, RNS2 is the call distribution corresponding radio resource according to Allocation/Retention priority, and sets up radio bearer.Under the situation of network congestion, this resource allocation will be referred to carry out seizing and lining up of Radio Resource according to Allocation/Retention priority.
In step 36, RNS2 returns the RAB assignment to MSC2 and finishes message (RAB AssignmentComplete).
In step 37～38, UE2 sends ALERTING message (ALERTING) by RNS2 to MSC2.
In step 39, MSC2 returns ACM message to MSC1, carries the call priority that redefines in this message.In order in ACM message, to carry call priority information, can in ACM message, expand " MLPP rank " as shown in table 1 field:
Table 1
Now, referring to Fig. 4:
At step X4, MSC1 judges whether carry " MLPP rank " field in the ACM message after receiving the ACM message that MSC2 returns, if having then continue execution in step X5 and X6.
At step X5, MSC1 sends the RAB assignment request message to RNS1, and carries the Allocation/Retention priority corresponding with the MLPP priority in the ACM message therein, and RNS1 revises Allocation/Retention priority with notice.
In the prior art, RAB Assignment Request message can be used for foundation/modification/deletion RAB.In the time need carrying out the modification of priority, only need in RABAssignment Request message, carry RAB sign (ID) and these two cells (IE) of Allocation/Retention Priority and get final product the RAB that has existed.As shown in table 2:

At step X6, RNS1 returns the RAB assignment to MSC1 and finishes message after finishing the modification of priorities associated parameter of RAB carrying.
In step 40～41, MSC1 notifies UE1: called terminal ringing.
In step 42 shown in Figure 5～45, called subscriber answer, MSC2 sends ANS message to MSC1.
In step 46 shown in Figure 4～47, MSC1 notice UE1 connects (CONNECT).
In step 48～51, set up being connected between calling UE and the called UE, calling subscriber and called subscriber converse.
So far, finish the call flows of in the UMTS network, implementing the inventive method.
As seen from the above-described embodiment, adopt technical solution of the present invention can obtain following beneficial effect:
1, the inventive method is under the situation of high-priority users the called subscriber, eMLPP priority based on the called subscriber promotes call priority, this method can guarantee that the user of high priority as calling subscriber or called subscriber the time, can both enjoy the high priority treatment;
2, the change to eMLPP business realizing flow process introduced of the inventive method can realize by the mode of revising software merely, not necessarily needs to carry out the change on the hardware, therefore realizes easily;
