The system configuration of SAE as shown in Figure 2.With reference to figure 2, the SAE system configuration is described.
201 subscriber equipmenies (hereinafter to be referred as UE) are the terminal equipments that is used for receiving data.202EUTRAN is the Radio Access Network among the evolution system SAE, also can be eNB, be responsible for providing the interface of access of radio network, and be connected by the S1 interface with user plane entity 204Serving Gateway with the mobile management entity 203MME of mobile phone to LTE (Long Term Evolution) mobile phone.203MME is in charge of mobile context, the session context of subscriber equipment, preserves user and security-related information.204Serving Gateway (Serving GW) mainly provides the function of user plane.S1-MME interface is responsible for providing RAB to set up to UE, and UE is sent to the forwarding of the message of MME from wireless access network.Some is similar for function that 203MME and 204Serving Gateway combine and original 206SGSN (GPRS (hereinafter to be referred as GPRS) support node), and MME and Serving Gateway might be in same physical entity.205PDN Gateway is responsible for functions such as charging, Lawful Interception.ServingGateway and PDN Gateway might be in same physical entity.206SGSN is that the transmission for data provides route among the present UMTS.Existing SGSN finds corresponding Gateway GPRS Support Node (hereinafter to be referred as GGSN) according to access point name (hereinafter to be referred as APN).207HSS is the local ownership subsystem of subscriber equipment, it is responsible for preserving user's information, comprises the current location of subscriber equipment, the address of service node, user's security-related information, packet data protocol (hereinafter to be referred as PDP) context that subscriber equipment activates or the like.208PCRF provides Qos policy and charging criterion by the S7 interface.
Usually, customer traffic is to 204Serving Gateway through 205PDN Gateway, Serving Gateway sends to the eNB at UE place to data by GPRS Tunnel Protocol (hereinafter to be referred as GTP) passage, and eNB sends to corresponding user equipment to data.
Fig. 3 is the structure of S1 interface among the SAE, and EPC is the core network of evolution.Wherein each eNB links to each other with a plurality of MME in MME pond (Pool).Each eNB links to each other with a plurality of S-GW among the S-GWPool.
H (e) NB (comprising 3G HNB, the HNB under LTE HNB and other connecting system) is the base station that is used in family, can also be applied to places such as university, company.H (e) NB is a plug and play.That H (e) NB comprises is opening, mixed type with the closed user group type.The difference of the H of closed user group type (e) NB and common macro base station is: common not every subscriber equipment can insert H (e) NB.Can insert H (e) NB of family such as the subscriber equipment that has only subscriber household, perhaps this household agrees the subscriber equipment that other can insert.Have only the employee of company and the affiliate of its company permission to insert in a company.There is one group of H (e) NB H (e) NB of same company (as be used in) of identical access customer group to be called closed user group (hereinafter to be referred as CSG, Closed Subscriber Group).The H of mixed type (e) NB also has the function of CSG, but the UE of right and wrong CSG can insert.Opening H (e) NB is the same with macro base station, the closed user group that neither one is specific.
The discussion for the scene of HeNB at present also has some disputes.What can reach common understanding is that the base station that is used in family is HeNB.About being used in the base station of little company, HeNB thinks in the company that has, and thinking of having should be the function that macro base station adds closed user group.That be used in shop, restaurant can be open HeNB, also can range macro base station (for example pico base station).

Embodiment
Be that example is described with the LTE system in following examples, the method among the present invention also can be used for the base station from home under other connecting system.Be be that example is described with UE moving from macro base station to the family expenses base station among the embodiment, method of the present invention is equally applicable to UE mobile from base station from home to the family expenses base station.
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 6, the method for switching of supporting in mobile communication system of the present invention's proposition may further comprise the steps:
Step 601:H (e) NB broadcasting HeNB cell information, the PLMN identification list that comprises support, TAC (Tracking Area Code), cell ID, the CSG sign, (this information element is used to indicate the type of HeNB or CSG in the indication of HeNB type, still the closed user group of mixed type in this way), the indication of HeNB length (be used to indicate the length of HeNB, represent as 1 and 28,0 represent 24).
The indication of HeNB or CSG type at present only need comprise mixed type and two values of closed user group.Because whether opening base station from home can be by in the broadcast message and have CSG to identify in the UE information of reporting to obtain, all need not be reported separately.If need not point out to be opening in the future separately but do not get rid of, perhaps there is new type to need base station from home notice UE or UE notification source base station, can represent by the value of expanding this indication.This invention is not limited to the indication of these two values.
Step 602:UE report HeNB cell information is given source base station, comprises ECGI (E-UTRAN Cell Global Identifier), CSG sign, the indication of HeNB type, the information indication of HeNB sign length or HeNB indication.
Wherein to be used for purpose sub-district, UE notification source base station be mixed type or the closed user group type and allow source base station know the sign length of purpose base station in the information indication of the indication of HeNB type and HeNB sign length.If it is a kind of that the length of HeNB ID has only, then allow source base station know that the purpose base station is that base station from home gets final product, the information indication of HeNB sign length can be the HeNB indication in this case, being used to indicate this base station is that base station from home also is non-base station from home.If in the future macro base station does not have the function of CSG, then the indication of HeNB type can comprise openly, and mixed type and three values closed user group type are not restricted to this three values certainly).If UE has reported the indication of HeNB type, source base station just knows that the purpose base station is a base station from home, and this does not indicate then that the purpose base station is a macro base station.The i.e. indication of HeNB type can be usually represented in the information indication of the indication of HeNB type and HeNB sign length with an information word in this case.
For more flexible and expansion, can be HeNB access style indication mixed type with two information elements, the closed user group type or opening.Indicate the length of HeNB sign with the indication of HeNB sign length.
The method according to this invention, source base station can obtain the CSG type of purpose base station from home and the length of HeNB sign, thereby support the switching of UE between macro base station and HeNB sub-district.Method of the present invention can also be used for ANR (for example source base station knows that according to the indication of HeNB indication or HeNB ID length the purpose base station is a base station from home, can not initiate to set up process to the X2 of purpose base station) and other purposes.
Fig. 7 is the UE indication (being the CSG indication) of reporting the HeNB type and HeNB indication or the HeNB Length Indication embodiment one to source base station.
Step 701, HeNB goes up the information that sends the HeNB sub-district at BCCH (Broadcast Control Channel).The PLMN identification list that comprises support, TAC, cell ID, CSG sign, the indication of HeNB type (the still closed user group type of mixed type), the indication of HeNB ID length.
Step 702, UE sends measurement report message to macro base station, and described message comprises PCI.
Step 703, macro base station distributes between the free area (idle period) to UE, and request UE reads the broadcast message of described PCI.
Step 704, UE reads the BCCH information of HeNB.
Step 705, UE reports ECGI, the CSG sign, the indication of HeNB type, the information indication of HeNB sign length, TAC, the PLMN identification list is given source base station.
Fig. 8 is the UE indication (being the CSG indication) of reporting the HeNB type and HeNB indication or the HeNB Length Indication embodiment two to source base station.
Step 801, HeNB goes up the information that sends the HeNB sub-district at BCCH (Broadcast Control Channel).The PLMN identification list that comprises support, TAC, cell ID, CSG sign, the indication of HeNB type (the still closed user group type of mixed type), the indication of HeNB ID length.
Step 802, macro base station send measures control messages to UE.Can comprise the long gap (free time) that distributes in order to allow UE read the BCCH of adjacent cell in the described message.
Step 803, UE reads the BCCH information of HeNB.
Step 804, UE sends measurement report message to macro base station, and described message comprises ECGI, the CSG sign, the indication of HeNB type, the information indication of HeNB sign length, TAC, the PLMN identification list is given source base station.
Fig. 9 is that the information that source base station utilizes UE to report is supported the embodiment one that S1 switches.The situation that does not have HeNB GW in the corresponding HeNB structure of this embodiment.The length of HeNB ID can be a kind of (for example 28), also can be multiple.Be detailed description below to this embodiment.Here ignored detailed description to known technology.
Step 901, source base station is reported according to the measurement of UE and is switched decision, if the purpose base station is that opening (UE does not report CSG ID, perhaps UE report purpose base station type is opening), then source base station utilizes the decision of existing technology whether to initiate handoff procedure to the purpose sub-district, for example according to the signal quality of purpose sub-district, the switching of UE limits tabulation etc.If the purpose sub-district is the closed user group type, then source base station needs also to judge that CSG sign that UE reports is whether in the CSG that can insert of UE tabulation, the CSG that can the insert tabulation how source base station obtains UE is not an emphasis of the present invention, ignores detailed technical descriptioon here.
If the CSG that UE reports is identified in the CSG that can the insert tabulation of UE, then source base station can be initiated to the handoff procedure of purpose sub-district, otherwise cannot.If the purpose sub-district is a mixed type, then no matter whether this UE is in the CSG of purpose base station group, and this UE can insert the purpose sub-district.
Step 902 is if the macro base station decision switches to the HeNB sub-district to UE.Macro base station sends " switching demand " message and gives MME (this embodiment switches to example explanation with the S1 under the same MME, if the switching between the different MME, the method in this invention is suitable equally).Comprise the HeNB ID unique under PLMN ID, the PLMN and the TAI of selection among the Target ID of macro base station in described " switching demand " message.The length of corresponding HeNB ID has only a kind of situation, macro base station is according to ECI (E-UTRAN cell ID) part of indication from the ECGI that UE reports of HeNB indication or HeNB ID length, length according to HeNB ID, obtain HeNB ID (preceding n the bit of CI, the length of the corresponding HeNB ID of n).MME sets up in the process at S1 and sets up the HeNB ID that request message has obtained the HeNB that it connected by S1.
The length of corresponding HeNB ID has two or more situations, if UE will switch to HeNB, the length of HeNB ID is known in the indication of the HeNB ID length that macro base station is reported according to UE, intercepts out corresponding HeNB sign (preceding n the bit of ECI, the length of n correspondence HeNB ID) then in ECI.
The length of corresponding HeNB ID has two or more situations, if it is the information of base station from home and can not obtain the indication information that base station from home indicates length that source base station only obtains the purpose base station from UE, macro base station comprises the sign ECI of PLMN sign and purpose sub-district in the Target ID of described " switching demand " message.MME knows that according to the length of purpose sign the purpose base station is not macro base station (the purpose sign of macro base station is 20bit, and ECI is 28bit), and MME intercepts out purpose HeNB ID according to the length of HeNB ID in ECI.
If for example the length of HeNB ID has 24bit and two kinds of length of 28bit.Wherein the preceding 24bit of the HeNB ID of 28bit is different with the value of 24bit HeNB ID.MME can find the HeNB ID of coupling respectively according to 24bit or 28bit like this.Perhaps MME knows according to preceding 24bit which kind of HeNB ID length is, and then obtains purpose HeNB ID according to the length of HeNB ID in ECI.
Step 903, MME finds the purpose base station according to PLMN ID and purpose HeNB ID, and sends " handoff request " message to purpose HeNB.
Step 904, HeNB sends " Handover Request Acknowledge " message and gives MME.
Step 905, MME sends switching command message to source base station.
Step 906, source base station send switching command message to UE.
Step 907, UE sends to switch and confirms to the purpose base station.
Step 908, purpose base station send switching notice to MME.
With source eNB UE being carried out access control in this embodiment is that example is described.If MME carries out access control to UE, the method among the present invention is suitable equally.As shown in figure 10.The method that corresponding MME carries out access control to UE, the process that S1 switches comprises step:
Step 1001, source base station are reported according to the measurement of UE and are switched decision, and source base station utilizes existing technology decision whether to initiate handoff procedure to the purpose sub-district, for example according to the signal quality of purpose sub-district, and the switching restriction tabulation of UE etc.
Step 1002 is if the macro base station decision switches to the HeNB sub-district to UE.Macro base station sends " switching demand " message and gives MME.Wherein how macro base station obtains the HeNB ID of purpose base station and how Target ID is set identical with the embodiment of Fig. 9, ignores detailed technical descriptioon here.Described message comprises CSG ID, indication of HeNB type or CSG indication.When CSG ID did not exist in the described message, the illustration purpose base station was opening.For the HeNB sub-district of style of opening, also can give MME by indication of HeNB type or CSG indication indication.
Step 1002, MME carries out access control to UE.If the purpose base station is opening (do not report CSG ID in the handoff requirement message, the indication of HeNB type or the CSG indication of perhaps reporting are opening), then UE can insert the purpose sub-district.If the purpose sub-district is the closed user group type, then MME judges that CSG sign in described " switching demand " message is whether in the CSG that can insert of UE tabulation, how MME obtains the CSG that can the insert tabulation of UE is ignored detailed technical descriptioon here, if the CSG in described " switching demand " message is identified in the CSG that can the insert tabulation of UE, then MME can be initiated to the handoff procedure of purpose sub-district, otherwise cannot.If the purpose sub-district is a mixed type, then no matter whether this UE is in described CSG group, and this UE can insert the purpose sub-district.MME utilizes UE whether to carry out traffic differentiation in the CSG tabulation.
Step 1004, if UE can insert Target cell, MME sends " handoff request " message and gives HeNB.Wherein how MME obtains the HeNB ID of purpose base station and follow-up process with identical described in Fig. 9, ignores detailed technical descriptioon here.
Step 1005, HeNB sends " Handover Request Acknowledge " message and gives MME.
Step 1006, MME sends switching command message to source base station.
Step 1007, source base station send switching command message to UE.
Step 1008, UE sends to switch and confirms to the purpose base station.
Step 1009, purpose base station send switching notice to MME.
Figure 11 is the method embodiment three that supports that S1 switches.This embodiment is corresponding to the situation that HeNB GW is arranged in the HeNB structure.The length of HeNB GW is the value of fixing.Be detailed description below to this embodiment.Here ignored detailed description to known technology.
Step 1101, source base station is reported according to the measurement of UE and is switched decision, if the purpose base station is that opening (UE does not report CSG ID, perhaps UE report purpose base station is opening), then source base station utilizes the decision of existing technology whether to initiate handoff procedure to the purpose sub-district, for example according to the signal quality of purpose sub-district, the switching of UE limits tabulation etc.If the purpose sub-district is the closed user group type, then source base station judges that CSG sign that UE reports is whether in the CSG that can insert of UE tabulation, the CSG that can the insert tabulation how source base station obtains UE is not an emphasis of the present invention, here ignore detailed technical descriptioon, if the CSG that UE reports is identified in the CSG that can the insert tabulation of UE, then source base station can be initiated to the handoff procedure of purpose sub-district, otherwise cannot.If the purpose sub-district is a mixed type, then no matter whether this UE is in the CSG of purpose base station group, and this UE can insert the purpose sub-district.
Step 1102 is if the macro base station decision switches to the HeNB sub-district to UE.Macro base station sends " switching demand " message and gives MME (this embodiment switches to example explanation with the S1 under the same MME, if the switching between the different MME, the method in this invention is suitable equally).Comprise the HeNB ID unique under PLMN ID, the PLMN and the TAI of selection among the Target ID of macro base station in described message.Wherein how macro base station obtains the HeNB ID of purpose base station and how Target ID is set identical with the embodiment of Fig. 9, ignores detailed technical descriptioon here.
Step 1103, MME knows that according to the length of HeNBID in the purpose sign purpose base station is not a macro base station, and MME intercepts corresponding length (for example preceding n the bit of HeNB ID) according to the front of the HeNB ID of length (for example n bit) in handoff requirement message of HeNB GW ID and obtains HeNB GW ID.MME sets up the HeNB GW ID that has obtained all HeNBGW that it connected in the process at S1.MME finds purpose HeNB GW according to HeNB GW ID, and sends " handoff request " message to HeNB GW.
Step 1104, HeNB GW finds HeNB according to the HeNB ID in the purpose sign.
Step 1105, the follow-up flow process that S1 switches is same as the prior art, ignores detailed technical descriptioon here.
This embodiment is in order to need the method among the present invention to look for HeNB GW or HeNB equally under the situation that HeNB GW existence is described.Access control also can be placed on MME.Do at MME under the situation of access control and HeNB GW existence, the method in this invention is suitable equally.MME finds HeNB GW or HeNB GW to find HeNB that other mode can be arranged, but need at first to know the purpose base station be HeNB or HeNB ID length to source base station.
Although the present invention is described according to described embodiment, it is pointed out that these embodiment are used for explaining, rather than be used for the present invention is limited.Those of ordinary skill in the art can be easy to these embodiment are changed, increase, delete any step and do not break away from the spirit and scope of the present invention.
