In the update mechanism of position provided by the invention, in the time that femto gateway receives the position updating request of user terminal, if user terminal location is upgraded before also within the service range of this femto gateway, femto gateway does not need user terminal location district update request message to be delivered to core net, but accept message by femto gateway to Home eNodeB or user terminal transmission position renewal, position updating process is ended to femto gateway inside, thereby alleviate the signaling burden of core net.For the position updating process that leaves femto gateway service range, core net notifies the femto gateway at this original place of user terminal to cancel the positional information of this user terminal after receiving the location area updating message of user terminal, thereby make femto gateway know that in time user terminal is whether still within its coverage, thereby be conducive to carrying out of Home eNodeB characteristic service.
Below in conjunction with the accompanying drawing in embodiments of the invention, the technical scheme in embodiments of the invention is clearly and completely described.
The embodiment of the present invention is applicable to 3G and LTE(Long Term Evolution, Long Term Evolution) system.Home eNodeB is called HNB in 3G system, in LTE system, is called HeNB; User terminal location point CS(circuit domain in 3G system) and PS(packet domain) two kinds, in CS, be called lane place (Location Area, LA), in PS, be called Route Area (Route Area, LA), in LTE system, user terminal location is referred to as tracking area (Tration Area, LA).Location update request message can be the location area updating request message in 3G system, or Routing Area Update request message, or other message of upgrading for user terminal location in 3G and LTE system.
The position update mechanism providing due to the embodiment of the present invention 3G with in LTE system to realize principle identical, flow process is similar, therefore following only to be embodied as example in 3G system, and the embodiment of the present invention is described in detail.
Embodiment mono-
The present embodiment has been described in 3G system, the position updating process of user terminal.The related system architecture of the present embodiment comprises user terminal, Home eNodeB and femto gateway.In the present embodiment, user terminal location is expressed with " lane place ", a corresponding lane place, one family base station.Under normal circumstances, in the time that user terminal moves on to another lane place from a lane place, will be to Home eNodeB launch position update request, with more new technological process of trigger position, position update flow also can trigger in the cycle certainly.In the time that femto gateway receives the position updating request of Home eNodeB forwarding, if user terminal location is upgraded before also within the service range of this femto gateway, femto gateway does not need user terminal location district update request message to be delivered to core net, but accept message by femto gateway to Home eNodeB or user terminal transmission position renewal, renewal process is ended to femto gateway inside.As shown in Figure 3, the user terminal location that the embodiment of the present invention one provides more new technological process can comprise:
Step 301, user terminal sends location area updating request message to Home eNodeB.
Conventionally, in the time that user terminal enters reposition district, set up RRC(Radio Resource Control with Home eNodeB, radio resource control) connect, and send NAS(Non-Access Stratum to Home eNodeB, Non-Access Stratum) message, i.e. lane place update request message, with more new technological process of trigger position district.
Step 302, Home eNodeB receives after this location area updating request message, judges whether to register, if need to register, performs step 303 rear execution register flow paths (being step 304 ~ step 306), performs step afterwards 307; If do not need registration, perform step 303 rear execution steps 307.
In this step, Home eNodeB can judge whether user terminal supports whether CSG and user terminal identification exist, if user terminal does not support not exist in CSG and Home eNodeB the mark of this user terminal, show to register this user terminal; If user terminal supports to have existed in CSG or Home eNodeB the mark of this user terminal, showing does not need this user terminal to register.
Step 303, Home eNodeB carries out access control to user terminal.This step is optional step.
Concrete, Home eNodeB can carry out access control to this user terminal according to user terminal identification and access control lists.For example, in the time that the IMSI of the user terminal that request is carried according to location area updating and the access control lists of Home eNodeB carry out access control, if the IMSI of user terminal in the access control lists of Home eNodeB, allows this user terminal access, otherwise refuse this user terminal access.
Step 304, Home eNodeB sends user terminal login request message to femto gateway.
In this step, the information such as portability IMSI, registration reason in this user terminal login request message.This is optional logon mode, and Home eNodeB also can carry out the registration process of user terminal by other means.
Step 305, femto gateway carries out access control according to user terminal identification and access control lists to user terminal after receiving the login request message of user terminal.This step is optional step.
Step 306, the login request message that femto gateway sends according to Home eNodeB carries out, after location registration process, returning to registration request response message.
Concrete, if Home eNodeB is accepted user terminal registration, sending registration to Home eNodeB and accept message, registration accepts to carry in message the contextual information of corresponding user terminal; If the registration of Home eNodeB refusal user terminal, can send registration reject message to Home eNodeB.
Step 307, the location area updating request message of user terminal is sent to femto gateway by Home eNodeB, and this location area updating request message carries the Location Area Code of this current position of user terminal.
Concrete, the Location Area Code in the location area updating request that Home eNodeB sends user terminal replaces with the Location Area Code of femto gateway, and the Location Area Code after replacing is carried on to location update request message transmission.
Step 308, when femto gateway receives after the location area updating request message of the Location Area Code that carries the current position of user terminal of Home eNodeB transmission, judges whether this user terminal moves in this femto gateway service range; In the time that femto gateway judges that this user terminal moves in this femto gateway service range, upgrade and accept message for this user terminal home position district.
Femto gateway generally possesses the ability of storage user's context (UE Context), in user's context, retaining the corresponding relation between user terminal identification and Home eNodeB, this corresponding relation can show the position (being which Home eNodeB user terminal is positioned at) of user terminal.After femto gateway receiving position update request, the UE Context storing according to it judges the position of this user terminal, if this user terminal corresponding Home eNodeB before location area updating also belongs to this home gateway administration, show user terminal before location area updating also within the service range of femto gateway, femto gateway does not need to send position updating request to core net, but the location area updating that directly generates this user terminal is received information, send to Home eNodeB, upgrade the positional information of respective user terminal in femto gateway simultaneously.If there is not the positional information (as the corresponding relation between user terminal identification and Home eNodeB) of this user terminal in femto gateway, illustrate user terminal before location area updating not within the service range of this femto gateway, need to report to core net the location area updating request message of this user terminal.
In above-mentioned flow process, in step 308, femto gateway can directly generate and send the renewal of described position and accept message to user terminal.
In above-mentioned flow process, if femto gateway is judging that user terminal stays out while moving in the base-station gateway service range of front yard, femto gateway need to be to the location area updating request message of core net report of user terminal.Femto gateway can be same as the prior art to core net report of user terminal location district update request message and follow-up processing flow thereof.
The normally lane place of femto gateway, lane place that core net is preserved, if user terminal before location area updating within the service range of this femto gateway, the positional information of the user terminal of core net storage does not change, according to flow process shown in Fig. 3, femto gateway does not need to the position of core net report of user terminal, thereby simple flow, saves signaling consumption and saves the processing expenditure of core net; If user terminal before location area updating not within the service range of this femto gateway, for core net, there is change in user terminal location, femto gateway need to, to the position of core net report of user terminal, upgrade with the position of completing user terminal.
Embodiment bis-
What provide based on embodiment mono-forms system by user terminal, Home eNodeB, femto gateway and core net, and the embodiment of the present invention two provides another kind of position update flow.In the present embodiment, in order to reduce the interacting message between Home eNodeB and femto gateway, also can be when Home eNodeB and femto gateway be registered user terminal the location area updating of completing user terminal.As shown in Figure 4, realization flow is as follows:
Concrete, it can be the flag bit increasing in user terminal registration request that indication information is upgraded in position, more ask by position the registration request triggering for representing, for example, in the time representing that the flag bit of position renewal indication information is 1, represent that user terminal registration request process is triggered by position updating request, in the time that flag bit is 0, represent that user terminal registration process is triggered by other business.If the user terminal registration process being triggered by other business, this registration process and follow-up flow process can be by existing procedure processing.
Concrete, can accept, in message, corresponding flag bit is set in registration and carry position updating type indication information.When femto gateway is accepted user terminal registration request, and when position updating type indication information indicates described registration request to upgrade initiation by position, whether femto gateway moves the value of the flag bit of desired location updating type indication information in this femto gateway service range according to user terminal: in the time that femto gateway is judging that user terminal moves in this femto gateway service range, can be 1 by the mark position of position updating type indication information, be used to indicate Home eNodeB and upgrade and accept message to this user terminal home position; Otherwise, be 0 by this updating type indication information mark position, position, be used to indicate Home eNodeB the location update request message receiving is transmitted to this femto gateway.Concrete determination methods is the same, does not repeat them here.
Concrete, in step 407 and step 408, Home eNodeB can be processed according to the value of step 406 Position Updating type indication information flag bit, and in the time that this flag bit is 1, Home eNodeB upgrades and accepts message to this user terminal home position; In the time that this flag bit is 0, this Home eNodeB forwards the location update request message of user terminal to femto gateway, follow-up processing flow can be with handling process of the prior art, as, femto gateway receives the location update request message that Home eNodeB reports, directly forward described location update request message to core net, the position that reception core net is returned is upgraded and is accepted message, and returns to this user terminal by Home eNodeB.
Concrete, in the time that Home eNodeB judgement does not need user terminal to register, Home eNodeB sends newly-increased signaling to femto gateway, receive the position updating request of user terminal in order to notify femto gateway Home eNodeB, in newly-increased signaling, carry position and upgrade indication information and user terminal identification, the flag bit that indication information can be newly-increased signaling is upgraded in position, and user terminal identification can be No. IMSI of user terminal.
Wherein, upgrading response message for described user terminal home position is specially: directly generate position renewal for described user terminal and accept message and return to the renewal of described position by Home eNodeB to user terminal and accept message.
