Embodiment
In order to make the application's object, technological means and advantage clearer, below in conjunction with accompanying drawing, the application is described in further details.
The application's basic thought is: when generation user face is congested, according to the information of the CAMEL-Subscription-Information of access user and/or access service, carry out the judgement foundation of user's switching or reorientation; Or, according to the business information that causes load capacity to rise, the judgement foundation of carrying out user's switching or reorientation.Thereby make when occurring that user's face is congested, can rationally carry out the judgement of user's switching or reorientation.
Particularly, a kind of mode can be kept at the information of the CAMEL-Subscription-Information of access user and/or access service in base station, by base station, according to corresponding information, carries out switch decision; Another kind of mode, also can be by MME according to the CAMEL-Subscription-Information of access user and/or the information of access service that obtain, carries out switch decision or provide the switching mode of suggestion, and notice is to base station.Below by specific embodiment, describe.
In embodiment mono-and embodiment bis-, be all the information of CAMEL-Subscription-Information and/or the access service of access user of being obtained from MME by base station, and carry out corresponding switch decision, but the process of obtaining corresponding information difference to some extent.Be elaborated below.
Embodiment mono-: be the process of user's access communication system
This embodiment be take LTE system as example, is applicable to too UMTS system.
Step 201, RRC process of establishing.
Step 202, base station sends initial UE message to MME, in this message, can carry new indication information, and indication MME need to provide the information of the congested needs of user's face.
Wherein, the CAMEL-Subscription-Information that the information of the congested needs of user's face is UE and/or the business information of access.The CAMEL-Subscription-Information of UE, for example, whether this UE is VIP user, or user's VIP rank etc.It can be APN information that user asks the business information of access, or can be also the type information of further concrete applied business, as this user asks accessing Internet business, MME need to know the concrete Internet service type of this user's access, as SKYPE, QQ, or other concrete applied business types.
This indication information can be optional parameters.For example, in some systems, MME just determines whether to provide user's CAMEL-Subscription-Information rank according to this parameter, or type of service parameter; But in some systems, if base station does not provide this new indication parameter, MME still provides user's CAMEL-Subscription-Information or business information.
Step 203:UE initiates access request message to MME.
Step 204:MME sends CAMEL-Subscription-Information request message the CAMEL-Subscription-Information of current UE is provided to HSS request HSS.
Step 205:HSS replys the CAMEL-Subscription-Information of this UE to MME.
Step 206:MME verifies current UE, if allow UE access, MME sends and sets up conversation request message to the SGW/PGW. business information that MME also can ask according to UE in this step, request SGW/PGW replys the particular type of current UE request access service, as traffic ID, or other can identify the information of concrete type of service.
Step 207:SGW/PGW replys and sets up session reply message to MME.
If MME asks concrete traffic type information.PGW also can reply to MME according to the concrete business information parsing.PGW resolves concrete traffic type information can realize this function on PGW, also can to PCRF, obtain by PGW.
Step 208:MME sends initial UE contextual information and is established to base station.
When the initial UE information sending when step 202 base station comprises described new indication information, in this step, MME can require MME that user's CAMEL-Subscription-Information or the specifying information that user asks the business of access are provided according to the indication of base station, base station in step 202, and user's signing class information (if whether this user is VIP user or user's VIP rank) and/or the traffic type information that user asks access are provided.
Certainly, in this step, MME also can directly send user's CAMEL-Subscription-Information and/or user asks the business information of access to base station, does not need the indication by base station.
Base station receives that CAMEL-Subscription-Information and/or user that MME sends ask the business information accessing.By the way, CAMEL-Subscription-Information or the traffic type information of all UE of current access can be collected in base station.
The traffic type information that base station can be accessed according to the CAMEL-Subscription-Information of the current UE receiving or user's request, thus whether when system generation user face is congested, determine to need this user is switched to other communities or this user is done to RRC release allows this UE reselect Xin community.
Embodiment bis-, and base station utilizes the CAMEL-Subscription-Information of the new S1 Procedure Acquisition UE defining and/or the business information of access.In this process, base station is according to the UE of current access, the business information accessing to the relevant CAMEL-Subscription-Information of MME request UE or current UE.
The flow process of specific embodiment two as shown in Figure 3, comprising:
Step 301, base station sends request the UE relevant information of access to MME.
Under base station, may have a plurality of UE accesses, base station can send the UE list of access to MME.The parameter of this UE can be eNB UE S1AP ID, or IMSI, TMSI, or other can identify the id information of UE.
Step 302, MME, according to the request of receiving, according to the UE list of base station requests, feeds back the CAMEL-Subscription-Information of UE or the business information of UE access.
The specific descriptions of the CAMEL-Subscription-Information of UE and the business information of access are shown in step 202.
Wherein, MME, when the feedback CAMEL-Subscription-Information of UE or the business information of access, can directly feed back the relevant information of all UE included in list.Or further, MME can also, according to the UE list of the base station requests of receiving, according to the CAMEL-Subscription-Information of the UE of all accesses or business information, determine whether to need to feed back all UE relevant informations.For example, MME can determine that base station only need to preserve the information of part UE, decide in the time of the congested generation of user's face, base station determines whether to carry out switching according to the information of the current UE receiving or RRC release allows part UE be switched to other communities or reselects to other communities.In this case, the relevant information that MME can only reply part UE is to base station.
Base station is received after UE relevant information (the CAMEL-Subscription-Information type of UE, or the traffic type information of UE access), can be preserved in base station side.In the time of the congested generation of user's face, whether base station determines to carry out according to the relevant information of UE switches or RRC dispose procedure.
In above-described embodiment one and embodiment bis-, base station obtains the CAMEL-Subscription-Information of UE and/or the business information of access and preserves from MME side.
Embodiment tri-, in handoff procedure, according to obtaining the CAMEL-Subscription-Information of UE and/or the business information of access, and carry out final switch decision.
Fig. 4 a and Fig. 4 b are that UE carries out the process of switching, and wherein the processing of step 401-402 is identical, specifically comprises:
Step 401, when user's face occurs congested time, base station is that a user carries out S1 and switches.
Even there is X2 interface between current base station and other base stations, base station 1 is still triggered S1 and is switched.
Step 402, base station sends handover request message to MME, carries the congested indication information of user's face in this message.
When MME receives the congested indication information of user's face, can there be following three kinds of different processing modes:
The first processing mode is as shown in the step 403a-403b in Fig. 4 a:
Step 403a, MME judges whether active user to be switched to other communities according to the congested indication information of user's face.
Whether MME, according to switching user's CAMEL-Subscription-Information and/or the business information of access, continues the judgement of switching.
Whether particularly, MME can check active user's CAMEL-Subscription-Information, judges this user's CAMEL-Subscription-Information rank, for example, be VIP user, or VIP user's rank.According to this class information, MME judges whether this UE can switch.Or MME checks the information of the business of active user's access, and operator can define some specific business, for this business, cannot switch.
If switched, can continue to carry out, according to existing switching flow, carry out.If switched, cannot continue, MME replys and switches refuse information, as step 404a.
Step 404a, MME reply to switch refuse information to base station, can carry the cause value of refusal in this message, and this cause value identifies the concrete reason that base station need to be considered to switch other user or indicate refusal, if this user is VIP user etc.Or this cause value also can be for the information of the CAMEL-Subscription-Information of identifying user and/or user's access service, the CAMEL-Subscription-Information that MME is replied in base station or the business information of access are kept at base station side.
Or the second processing mode is as shown in the step 403b-404b in Fig. 4 b:
At MME, receive after step 402 execution step 403b: according to the indication information of step 402, to base station feedback, switch user's CAMEL-Subscription-Information or the business information of user's access.
MME does not need to carry out switch decision in this case.Whether base station determines to continue to carry out to switch according to all users' that access the CAMEL-Subscription-Information of preserving or the business information of access.Wherein, the user signing contract information of MME feedback and/or the business information of access can be carried to be switched in refuse information, performs step 403b, and this message can be that existing switching refuse information can be also the message of new definition.
Step 403b, MME sends and switches refuse information to base station, carries user's CAMEL-Subscription-Information or the business information of user's access in this message.This message can be also the S1AP message of new definition, carries user's CAMEL-Subscription-Information or the business information of user's access in this message.
Step 404b, user's CAMEL-Subscription-Information or the business information of user's access are received in base station, carry out switch decision.If active user allows to be switched to other communities, carry out according to existing handoff procedure base station.If do not allow to be switched to other communities, base station refusal switches and continues to carry out.
Or, the third processing mode:
MME receives after step 402, execution step 403a: determine that according to the indication in step 402 need to solve user's face congested, the cell ID that MME can access according to current UE, search the CAMEL-Subscription-Information of UE and the business information of access of other accesses in corresponding Gai community, and according to corresponding information, to base station, send other users' of suggestion switching information.
For example the user's of current switching CAMEL-Subscription-Information rank is higher, and MME can find the rank of the CAMEL-Subscription-Information of other UE in current area, and MME can pass through step 404a, carries other users' of suggestion switching information in switching refuse information.Other users' information can represent with S-TMSI or MME UE S1AP or other id informations that can identify user.The switching refuse information of step 404a can be that existing switching refuse information can be also the message of new definition.Base station is received and is switched after refuse information, other users' information in the handoff advice that can send according to MME, and execution is switched, thereby other users are switched to other communities.
In addition, MME, when receiving 402 and performing step 403a, asks according to active user's CAMEL-Subscription-Information or user the business information accessing, judge whether active user can carry out switching, meanwhile, further, whether MME can consider can allow active user be switched in other connecting systems.Accordingly, MME can carry the information that suggestion UE is switched to other connecting systems in execution step 404a.Receive after 404a base station, according to the indication of MME, switches user to other connecting systems.
Embodiment tetra-, when generation user face is congested, by MME, to base station, send handoff advice.
In the present embodiment, the user's of MME statistics access information, determines according to the user's of all accesses information how direct base station determines whether some specific users to be switched to other communities or to allow some users again arrive other communities.
Fig. 5 is the particular flow sheet of embodiment tetra-, as shown in Figure 5, comprising:
Step 501, UE transmission access request message or other NAS request messages are to MME.
Step 502, in each access procedure, MME collects the information of current UE, comprises the CAMEL-Subscription-Information of UE and/or the traffic type information of UE request access, the community id information of UE access; Further, MME also can collect the load information that base station regularly sends, and makes statistics.Specifically can add up by the form shown in Fig. 5.
MME can count under some communities, all users' that access information, the CAMEL-Subscription-Information that all users are corresponding, or the information of the business that accesses of all users.MME can periodically report current load information according to base station and make statistics.For example MME can count in set time section, certain user's custom, and some UE accesses some specific business below certain cell that is everlasting.If control need to be made by operator, the load capacity that for example some specific transactions causes rises.The business information that MME can record these users or cause load capacity to rise.
MME can pass through step 503, sends suggestion base station and carries out the UE list of switching, or send the business information that causes load of base station amount to rise, as APN sign or QCI.Base station can determine whether to carry out RRC according to this information to be discharged or handoff procedure, allows part UE be switched to other communities.
Step 503, MME sends and can allow base station carry out the UE list of switching or cause the business information of load capacity rising to base station.
Whether base station determines to need to carry out to switch or RRC dispose procedure according to the user profile list of receiving or business information.If discharging, RRC performs step 504.
In above-mentioned four embodiment, introduced and in the application, carried out the process of switch decision.Wherein, according to the business information of the CAMEL-Subscription-Information of UE and/or access, specifically adjudicate.Here, decision rule can arrange voluntarily according to different needs and strategy, guarantees the user's that signing rank is high business continuance etc. as arranged as required, specifically belongs to those skilled in the art's common technology means, just repeats no more here.
Embodiment five:
In above-mentioned several embodiment, when base station determines to allow certain UE be switched to other communities, base station is switched to the process of other communities or process that base station is reoriented to UE other communities as shown in embodiment five UE.
Steps A, when base station determines to allow UE be switched to other communities, base station can trigger S1 or X2 switches, and object is to allow UE be switched to other communities.
Or,
B.1, base station determines current UE to be reoriented to other communities to step, and base station triggers RRC discharges, and carries the information of reorientation community in this message.
B.2, UE, according to the indication of base station, carries out cell reselection procedure to step.
Specific implementation from above-mentioned the application, in the application, base station obtains the CAMEL-Subscription-Information of access user and/or the business information accessing from MME, thereby occur when congested at user's face, can rationally carry out according to corresponding information the judgement of user's switching and reorientation, further can pass through relative set, guarantee the contracted user's that rank is high business experience.Or, can be by MME according to the CAMEL-Subscription-Information of access user and/or the business information that accesses, handoff advice while providing generation user face congested for base station, switch or reorientation according to corresponding suggestion base station, thereby can rationally carry out switch decision equally, guarantee the contracted user's that rank is high business experience.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of protection of the invention.
