Embodiment
In order to solve in the prior art, when the position that femto gateway carries out user terminal is upgraded, when not changing, the positional information of core net user terminals stored still receives the updating record that femto gateway is uploaded, the problem that causes unnecessary signaling consumption, the embodiment of the invention provide a kind of position update mechanism.
In the update mechanism of position provided by the invention, when family's base-station 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, then femto gateway does not need user terminal location district update inquiry information is delivered to core net, but accept message to Home eNodeB or user terminal transmission position renewal by femto gateway, position updating process is ended at femto gateway inside, thereby alleviate the signaling burden of core net.For the position updating process that leaves the femto gateway service range, core net receives that the femto gateway of notifying this original place of user terminal after the location area updating message of user terminal cancels the positional information of this user terminal, thereby make femto gateway in time know user terminal whether still within its coverage, thereby help carrying out of Home eNodeB characteristic service.
Below in conjunction with the accompanying drawing in the embodiments of the invention, the technical scheme in the embodiments of the invention is clearly and completely described.
The embodiment of the invention is applicable to 3G and LTE(Long Term Evolution, Long Term Evolution) system.Home eNodeB is called HNB in the 3G system, be called HeNB in the LTE system; User terminal location is divided the CS(circuit domain in the 3G system) and the PS(packet domain) two kinds, in CS, be called lane place (Location Area, LA), in PS, be called route district (Route Area, LA), in the LTE system user terminal location be referred to as tracking area (Tration Area, LA).Location update request message can be the location area updating request message in the 3G system, or the Routing Area Update request message, or other are used for the message that user terminal location is upgraded in 3G and the LTE system.
Because the position update mechanism that provides of the embodiment of the invention is identical with realization principle in the LTE system at 3G, flow process is similar, therefore below only in the 3G system, to be embodied as example, the embodiment of the invention is described in detail.
Embodiment one
Present embodiment has been described in the 3G system, the position updating process of user terminal.Comprise user terminal, Home eNodeB and femto gateway in the related system architecture of present embodiment.In the present embodiment, user terminal location is expressed with " lane place ", corresponding lane place, one family base station.Generally, when user terminal when a lane place moves on to another lane place, will initiate position updating request to Home eNodeB, with trigger position new technological process more, but certainly the position more new technological process also the cycle triggers.When family's base-station 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, then femto gateway does not need user terminal location district update inquiry information is delivered to core net, but accept message to Home eNodeB or user terminal transmission position renewal by femto gateway, renewal process is ended at femto gateway inside.As shown in Figure 3, the user terminal location that provides of the embodiment of the invention one more new technological process can comprise:
Step 301, user terminal sends the location area updating request message to Home eNodeB.
Usually, when user terminal enters the reposition district, set up RRC(Radio Resource Control with Home eNodeB, radio resource control) connects, and to Home eNodeB transmission NAS(Non-Access Stratum, Non-Access Stratum) message, i.e. lane place update inquiry information is with trigger position district new technological process more.
After step 302, Home eNodeB receive this location area updating request message, judge whether and need register, register if desired that then register flow path (being step 304 ~ step 306) is carried out in execution in step 303 backs, execution in step 307 afterwards; If do not need registration, execution in step 303 back execution in step 307 then.
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 the Home eNodeB sign of this user terminal, then show and to register this user terminal; If user terminal supports to have existed in CSG or the Home eNodeB sign of this user terminal, then showing does not need this user terminal is registered.
Step 303, Home eNodeB carries out access control to user terminal.This step is an 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, when the IMSI of the user terminal that carries in the request 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, then allows this user terminal to insert, insert otherwise refuse this user terminal.
Step 304, Home eNodeB sends the user terminal login request message to femto gateway.
In this step, 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 modes.
Step 305, femto gateway receives after the login request message of user terminal, according to user terminal identification and access control lists user terminal is carried out access control.This step is an optional step.
Step 306 after the login request message that femto gateway sends according to Home eNodeB is carried out location registration process, is returned the register requirement response message.
Concrete, if Home eNodeB is accepted the user terminal registration, then sending registration and accept message to Home eNodeB, registration accepts to carry in the message contextual information of corresponding user terminal; If the registration of Home eNodeB refusing user's terminal can send registration reject message to Home eNodeB.
Step 307, Home eNodeB is sent to femto gateway with the location area updating request message of user terminal, 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 will replacing is carried on the location update request message transmission.
Step 308 behind the location area updating request message of the Location Area Code that carries the current position of user terminal that family's base-station gateway reception Home eNodeB sends, judges whether this user terminal moves in this femto gateway service range; Judge this user terminal in this femto gateway service range when mobile when family's base-station gateway, upgrade at this user terminal home position district and accept message.
Femto gateway generally possesses the ability of storage user's context (UE Context), in user's context, keeping the corresponding relation between user terminal identification and the Home eNodeB, this corresponding relation can show the position (being which Home eNodeB user terminal is positioned at) of user terminal.After the femto gateway receiving position update request, judge the position of this user terminal according to its UE Context that stores, if this user terminal corresponding Home eNodeB before location area updating also belongs to this home gateway administration, show that promptly user terminal is before the location area updating also within the service range at femto gateway, then 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 the Home eNodeB) of this user terminal in the femto gateway, illustrate that then user terminal before the location area updating not within the service range at this femto gateway, need report the location area updating request message of this user terminal to core net.
Step 309 when the family base station receives location area updating that femto gateway sends when accepting message, is transmitted this location area updating to user terminal and is accepted message.
In the 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 the above-mentioned flow process, if femto gateway is judging that user terminal stays out in the base-station gateway service range of front yard when mobile, femto gateway need 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's update inquiry information and follow-up processing flow thereof.
The lane place that core net is preserved is the lane place of femto gateway normally, if user terminal is within the service range at this femto gateway before the location area updating, then the positional information of core net user terminals stored does not change, according to flow process shown in Figure 3, femto gateway does not need the position to core net report of user terminal, thereby the simplification flow process, the processing expenditure of saving signaling consumption and saving core net; If user terminal is before the location area updating not within the service range at this femto gateway, then for core net, change has taken place in user terminal location, and femto gateway need upgrade with the position of finishing user terminal to the position of core net report of user terminal.
Embodiment two
Form system based on what embodiment one provided by user terminal, Home eNodeB, femto gateway and core net, the embodiment of the invention two provides more new technological process of another kind of position.In the present embodiment, in order to reduce the interacting message between Home eNodeB and the femto gateway, also can when registering user terminal, Home eNodeB and femto gateway finish the location area updating of user terminal.As shown in Figure 4, realization flow is as follows:
After step 402, Home eNodeB received this location update request message, Home eNodeB judged whether user terminal needs to register, and registers if desired, then execution in step 403 back execution in step 404; If do not need registration, execution in step 403 back execution in step 409 then.
Concrete, it can be the flag bit that increases in the user terminal register requirement that indication information is upgraded in the position, be used to represent more ask the register requirement that triggers by the position, for example, when the flag bit of expression position renewal indication information is 1, expression user terminal register requirement process is triggered by position updating request, and when flag bit was 0, expression user terminal registration process was by other professional triggerings.If by other professional user terminal registration processes that triggers, then this registration process and follow-up flow process can be handled by existing procedure.
Concrete, can accept to be provided with in the message corresponding marker bit in registration and carry position updating type indication information.When family's base-station gateway is accepted the user terminal register requirement, and when position updating type indication information indicates described register requirement to upgrade initiation by the 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: when family's base-station gateway is judging that user terminal is in this femto gateway service range when mobile, can be 1 with the mark position of position updating type indication information, be used to indicate Home eNodeB to upgrade and accept message to this user terminal home position; Otherwise, be 0 with this updating type indication information mark position, position, be used to indicate Home eNodeB that the location update request message that receives 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 handled according to the value of step 406 Position Updating type indication information flag bit, and when this flag bit was 1, Home eNodeB upgrades to this user terminal home position accepted message; When this flag bit is 0, this Home eNodeB is transmitted 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 transmit described location update request message to core net, the position that the reception core net is returned is upgraded and is accepted message, and returns to this user terminal by Home eNodeB.
Concrete, when the family base station is judged when not needing user terminal registered, Home eNodeB sends newly-increased signaling to femto gateway, receive the position updating request of user terminal in order to notice femto gateway Home eNodeB, carry the position in the newly-increased signaling and upgrade indication information and user terminal identification, the flag bit that indication information can be newly-increased signaling is upgraded in the position, and user terminal identification can be IMSI number of user terminal.
Step 411, upgrade response message at described user terminal home position, or, the response message of the newly-increased signaling of returning to described Home eNodeB, carrying value in the response message of described newly-increased signaling is the position updating type indication information of first numerical value, and Home eNodeB is that the position updating type indication information of first numerical value is accepted message to described user terminal home position renewal according to described value.
Wherein, upgrading response message at described user terminal home position is specially: directly generate the position at described user terminal and upgrade and accept message and return described position by Home eNodeB to user terminal and upgrade and accept message.
By above description as can be seen, Home eNodeB is after the location update request message that receives the user terminal transmission, if user terminal needs registration, indication information is upgraded in the position to be carried in the login request message to user terminal, if user terminal does not need registration, the newly-increased signaling that indication information is upgraded in the position is carried in transmission, when femto gateway receives described login request message or newly-increased signaling, judge whether this user terminal moves in this femto gateway service range, and in corresponding response information, carry position updating type indication information according to judged result, be used to indicate Home eNodeB to accept position updating request or report location update request message.When the position renewal occurs in same femto gateway inside, femto gateway does not need the position to core net report of user terminal, thereby simplification flow process, the processing expenditure of saving signaling consumption and saving core net, the position updating request of carrying user terminal by registration message reports gateway simultaneously, and accept message to the renewal of user terminal home position by femto gateway indication Home eNodeB, do not need Home eNodeB that the position updating request of user terminal is transmitted to femto gateway, reduced the Signalling exchange of Home eNodeB and femto gateway, the position of having simplified user terminal is new technological process more.
Embodiment three
In embodiment two, Home eNodeB sends to femto gateway and carries registration message or the newly-increased signaling that indication information is upgraded in the position, and according to the information of femto gateway response, confirm the position updating request of user terminal or the location update request message of report of user terminal, for femto gateway, in case receive the location update request message that Home eNodeB sends then directly be transmitted to core net.The embodiment of the invention three provides more new technological process of another kind of position.In the present embodiment, when registering user terminal, Home eNodeB and femto gateway finish the location area updating of user terminal, when user terminal did not need to register, Home eNodeB directly sent the location update request message of user terminal to femto gateway.As shown in Figure 5, realization flow is as follows:
Step 501 is identical with step 401 in the flow process shown in Figure 4.
Further, before execution in step 504 or step 509, Home eNodeB also can carry out access control to user terminal.
Step 504 ~ 507, identical with step 404 ~ 407 in the flow process shown in Figure 4.
Step 508, femto gateway returns user's registration to Home eNodeB and accepts message, and this user's registration accepts to carry in the message position updating type indication information, and this position updating type indication information is used to indicate Home eNodeB to accept position updating request; Home eNodeB receives user's registration that femto gateway returns and accepts message, and Home eNodeB is accepted the value of the position updating type indication information that message carries according to user's registration, sends the location update request message of user terminal to femto gateway;
Femto gateway receives the location update request message that Home eNodeB is transmitted, whether sent this login request message before judging this Home eNodeB, if, femto gateway is transmitted location update request message to core net, the position that the reception core net is returned is upgraded and is accepted message, and returns to user terminal by Home eNodeB.
The location updating method that provides by the embodiment of the invention, Home eNodeB is after the location update request message that receives the user terminal transmission, if user terminal needs registration, indication information is upgraded in the position to be carried in the login request message to user terminal, if user terminal does not need registration, send the location update request message of user terminal, femto gateway receives described login request message, judge whether this user terminal moves in this femto gateway service range, and the indication Home eNodeB is accepted position updating request or is reported location update request message, when femto gateway receives location update request message, judge whether that earlier whether user terminal was registered before, judged whether and position updating request need be reported core net.By the location updating method that the embodiment of the invention provides, reduced the core net burden, reduced the Signalling exchange of Home eNodeB and femto gateway, the position of having simplified user terminal is new technological process more.
Embodiment four
The embodiment of the invention four provides more new technological process of a kind of position, the location area updating flow process of initiating when this flow process is left the femto gateway coverage at user terminal in the prior art is improved, and promptly core net receives that the femto gateway that will notify this original place of user terminal after the location update request message of user terminal cancels the relevant information of this user terminal.The two kinds of situations that comprise are moved in the position that present embodiment relates to: a kind of situation is that user terminal leaves from the one family base station cell and enters a macrocell; Another kind of situation is that user terminal leaves from the one family base station cell and enters another home base station cells, the femto gateway difference at these two home cell places.In position that present embodiment provides more in the new technological process, receive the location update request message of user terminal when core net after, except carrying out conventional processing, also need further to check the old lane place of user terminal, if the new and old lane place difference of this user terminal, and old lane place shows that user terminal was positioned at the area of coverage of the femto gateway in a Geju City (femto gateway that promptly is different from the current place of user terminal) originally, then send the canceling position message of this user terminal, to indicate the relevant information of this femto gateway cancellation relative users terminal to this femto gateway.
As shown in Figure 6, this flow process can comprise:
Step 601 ~ 604, identical with step 201 ~ 204 in the flow process shown in Figure 2, promptly, when user terminal enters macrocell from home base station cells, the trigger position district is new technological process more, the location area updating request message that user terminal sends is triggered to core net, and after the completing place was upgraded, core net home position district upgraded and accepts message.
Step 605, core net judge whether occurrence positions changes user terminal, and whether whether user terminal is positioned at the femto gateway coverage before changing, promptly leave in one family base-station gateway coverage; If this user terminal occurrence positions change, and the position is positioned at the femto gateway coverage before changing then sends the canceling position indication information to before changing femto gateway.
Concrete, when core net is received the location update request message of user terminal, before upgrading in the core net storage the user terminal corresponding position information in the lane place promptly corresponding to the user terminal femto gateway at place before changing.
Comprise user terminal identification (as IMSI) in the canceling position indication information.
The femto gateway of step 606, source home base station cells correspondence receives after the canceling position indication information of core net transmission, carries out respective handling according to this canceling position indication information, and can further send the canceling position confirmation to core net.
Usually, femto gateway stores context (UE Context) information of user terminal, has wherein write down the relation of the correspondence of user terminal and Home eNodeB.In this step, femto gateway can according to the canceling position indication information delete this user terminal context (UE Context) information or/wherein the user terminal and the relation of the correspondence of Home eNodeB etc. just.
Step 607, this femto gateway send a notification message to Femto business platform (being the Home eNodeB business platform), and this user terminal of notice Femto business platform has left Home eNodeB.This step is an optional step.
Comprise user terminal identification (as IMSI) etc. in the notification message.
Step 608, Femto business platform upgrade the corresponding information of this user terminal, send acknowledge message to described femto gateway.This step is an optional step.
Step in the above-mentioned flow process does not have strict sequential requirement, as the order interchangeable of step 606 and step 607.
