Concrete, as SIB1 (System Information Block 1, system information block 1) middle CSG (ClosedSubscriber Group, close subscriber group) Indicator (indication)=false, when CSG ID (mark)=present, this HeNB, for mixing (hybrid) access module, now, allows CSG Member Users and non-CSG Member Users access.Wherein, for CSG Member Users, this community is similar to CSG community, and for non-CSG Member Users, this community is similar to normal macrocell.
As CSG Indicator=true, when CSG ID=not present, this HeNB is open (open) access module, and in the time that HeNB is configured to open mode, according to roaming agreement, HeNB can provide business for the contracted user who belongs to any PLMN (Public Land Mobile-communication Network, public land mobile communication network) and do not belong to its corresponding CSG.Wherein, for UE (User Equipment, subscriber equipment), this community and common macrocell are similar.
In addition, mixed cell provides the different grades of service to Member Users and non-CSG Member Users, and the service of the lowest class is paging, and now mixed mode community allows non-CSG Member Users to access community and obtains paging.Wherein, if a mixed cell only provides paging service to non-CSG Member Users, the interference of data channel will be similar with CSG HeNB.In the time that mixed cell determines that a UE is switched to macrocell, Home eNodeB need to carry out relevant interference coordination work to macrocell.Further, if mixed cell provides data service for non-CSG Member Users, blended family base station and lower powered Pico community are similar, difference to some extent in Member Users and non-CSG Member Users's the grade of service.

1, COS, the QoS (Quality of Service, service quality) that Home eNodeB provides for non-CSG Member Users guarantees to wait and safeguarded by Home eNodeB self, for macro base station and grand UE, do not know this situation.
2, switch for inbound, grand UE is owing to not knowing the COS of Home eNodeB, can (for example have a negative impact to the mobility of UE, non-CSG Member Users is switched back macro base station by Home eNodeB, thereby cause the generation of pingpang handoff), and can cause the waste of a large amount of space interface signalings.
3, the type of service that lacks support can impact the function in Home eNodeB self-optimizing, for example, in load balancing process, if macro base station is not understood the available COS of Home eNodeB, and one of indication can only provide the Home eNodeB of paging service to go increasing power to absorb the load of macro base station, not only can not solve load problem, also can cause the increase of interference, thereby cause the appearance of the negative factors such as call drop.

The technical scheme providing in order more clearly to set forth the embodiment of the present invention, discusses the indicating means of this COS in detail below in conjunction with specific embodiment.
The embodiment of the present invention two provides a kind of indicating means of COS, in the present embodiment, in broadcast, carry COS describes as example take Home eNodeB, now, Home eNodeB need to increase indication information (being used to indicate the COS of Home eNodeB to non-CSG Member Users) in broadcast, and UE need to increase relevant information (for representing the COS of Home eNodeB to non-CSG Member Users) in the message reporting, as shown in Figure 2, the method comprises the following steps:
Step 201, Home eNodeB sends indication information in broadcast, and this indication information is for representing the COS that this Home eNodeB provides for non-CSG Member Users.Wherein, the Home eNodeB that the Home eNodeB in the embodiment of the present invention is mixed mode, for convenience of description, describes as an example of Home eNodeB example in the embodiment of the present invention.
For example, this Home eNodeB can send indication information in SIB1 message, and this indication information can use a bit or multiple bit to represent.Certainly, in practical application, can also in other SIB message, send indication information, in the embodiment of the present invention, repeat no more.
Step 202, UE sends and measures reporting message to source base station.Wherein, this source base station is any base station except above-mentioned Home eNodeB, and for example, this source base station can be the base station of macro base station or other types.
The content of carrying in this measurement reporting message includes but not limited to: the PCI (PhysicalCell Identity, physical-layer cell identifier) of this Home eNodeB, signal strength information, signal quality information etc.
Concrete, in the time that UE need to be switched to this Home eNodeB (being target Home eNodeB) from source base station, this UE need to measure this target Home eNodeB, and sends and measure reporting message to source base station according to measurement result.
Step 203, source base station indicates this UE to read the system information of target Home eNodeB.
Concrete, when source base station receives after the measurement report of UE, source base station need to judge whether this UE can be switched to target Home eNodeB, and this source base station also needs to know the COS of target Home eNodeB to non-CSG Member Users, therefore, this source base station need to indicate UE to read the system information of target Home eNodeB, for example, in this system information (, SIB1 message), has carried the COS of target Home eNodeB to non-CSG Member Users.
In the embodiment of the present invention, this source base station can pass through RRC (Radio Resource Control, Radio Resource control) connect reconfiguration message indicate this UE to read the system information of target Home eNodeB, certainly, in practical application, the message that also can use other types, repeats no more in the embodiment of the present invention.
Step 204, UE reads the system information of target Home eNodeB, and knows the COS of target Home eNodeB to non-CSG Member Users.
Concrete, because target Home eNodeB sends indication information in the mode of broadcast, in system information, will carry this indication information, in system information, will carry the COS of target Home eNodeB to non-CSG Member Users.
Step 205, the indication of UE COS to non-CSG Member Users by target Home eNodeB reports source base station.
Concrete, after knowing that target Home eNodeB is to non-CSG Member Users's COS, this UE can be by measurement report (sending in the mode of measuring reporting message) indication of the COS by target Home eNodeB to non-CSG Member Users report source base station.
For example, target Home eNodeB is COS 1 to non-CSG Member Users's COS, and being designated as of COS 1 correspondence indicated 1 o'clock, and UE need to be by the information reporting of indication 1 to source base station.
Step 206, source base station is determined the COS of target Home eNodeB to non-CSG Member Users according to measurement report.
Concrete, after receiving the measurement of UE and reporting, if do not carry the indication of COS in measurement report, source base station is selected the COS of acquiescence, for example, the COS of acquiescence is while being data service, determine target Home eNodeB to non-CSG Member Users's COS for data service is provided.If carry the indication of COS in measurement report, source base station is determined the COS of target Home eNodeB to non-CSG Member Users according to the indication of this COS, for example, COS be designated as data service time, determine target Home eNodeB to non-CSG Member Users's COS for data service is provided.
Further, source base station also needs, according to target Home eNodeB, non-CSG Member Users's COS is carried out to respective handling, in this processing procedure embodiment of the present invention, repeats no more.
The embodiment of the present invention three provides a kind of indicating means of COS, in the present embodiment, in the message of X2 interface, carry COS describes as example take Home eNodeB, now, Home eNodeB need to be the indication information of X2 interface transferring service type (being used to indicate the COS of Home eNodeB to non-CSG Member Users), when receiving after this indication information, target BS can be known the COS that Home eNodeB is current supported.
Concrete, for example, in the time that Home eNodeB and other base stations (be target BS,, macro base station or other Home eNodeB etc.) sets up X2 interface, can utilize the related news that X2 interface is set up to indicate the COS of Home eNodeB to non-CSG Member Users.
In the embodiment of the present invention, in the time that Home eNodeB is initiated X2 process of establishing, Home eNodeB can increase the information of the COS of indication Home eNodeB to non-CSG Member Users in X2SETUP REQUEST (X2 sets up request) message.
In the time that target BS is initiated X2 process of establishing, Home eNodeB can increase the information of the COS of indication Home eNodeB to non-CSG Member Users in X2 SETUPRESPONSE (X2 sets up response) message.
It should be noted that, the information of the COS of this indication Home eNodeB to non-CSG Member Users includes but not limited to following content: the non-CSG Member Users COS of the CSG ID of Home eNodeB, the CSG Indicator of Home eNodeB, Home eNodeB.
IE (information elements, information element) corresponding to non-CSG Member Users COS that it should be noted that this Home eNodeB is option, and this IE can represent with a bit or multiple bit.
In the time that this IE does not exist, target BS will be selected the COS of acquiescence, for example, when the COS of acquiescence is data service, determine target Home eNodeB to non-CSG Member Users's COS for data service is provided.
In the time that this IE exists, target BS need to be determined the COS of Home eNodeB to non-CSG Member Users according to this IE, for example, when this IE is data service, determine target Home eNodeB to non-CSG Member Users's COS for data service is provided.
Certainly, in actual applications, be not limited to the information that increases the COS of indication Home eNodeB to non-CSG Member Users in X2 SETUP REQUEST message or in X2 SETUP RESPONSE message, for other the message based on X2 interface, in the embodiment of the present invention, repeat no more.
In addition, it should be noted that, after Home eNodeB is determined non-CSG Member Users's COS, Home eNodeB can also be adjusted non-CSG Member Users's COS (for example, Home eNodeB is because the reasons such as load or strategy are determined and need to be adjusted non-CSG Member Users's COS).
Now, Home eNodeB can also increase relevant indication in ENB CONFIGURATION UPDATE (ENB config update) message, and the current Home eNodeB in notification target base station changes for non-CSG Member Users's COS.Wherein, in ENB CONFIGURATION UPDATE message, can increase but be not limited to following content: the non-CSG Member Users COS (COS after changing) of Home eNodeB, this IE can represent with a bit or multiple bit.
The embodiment of the present invention four provides a kind of indicating means of COS, in the present embodiment, with Home eNodeB by the indication information of COS (being used to indicate the COS of Home eNodeB to non-CSG Member Users) notify its management equipment HeMS (by with interface of HeMS etc.), and by this HeMS by Home eNodeB the indication information of the COS to non-CSG Member Users to notify to other base stations (be target BS, for example, macro base station or other Home eNodeB etc.).
Concrete, Home eNodeB can utilize TR-069 agreement to notify its management equipment HeMS by the indication information of COS, for example, Home eNodeB can carry the COS of this Home eNodeB to non-CSG Member Users in PM File Upload Procedures, and periodically reports HeMS.
Further, other base stations can obtain the COS that this Home eNodeB provides for non-CSG Member Users by HeMS.Wherein, the mode that other base stations (be Home eNodeB base station corresponding to adjacent area around, describe as an example of target BS example) obtains the COS of this Home eNodeB from HeMS includes but not limited to:
(1) COS of this Home eNodeB of HeMS proactive notification target BS to non-CSG Member Users.For example, HeMS adopts the SetParameterValues RPC method defining in TS32.593 agreement to go the COS of this Home eNodeB of notification target base station to non-CSG Member Users.
(2) target BS initiatively obtains the COS of Home eNodeB to non-CSG Member Users from HeMS.
The embodiment of the present invention five provides a kind of indicating means of COS, in the present embodiment, describes as an example of the process of carrying out load balancing between Home eNodeB and macro base station example.Wherein, Home eNodeB HeNB1 is for non-CSG Member Users supported data business, and HeNB2 only supports paging service for non-CSG Member Users, and its network topological diagram as shown in Figure 3.As shown in Figure 4, the method comprises the following steps:
Step 401, the macro base station statistics of periodically load, in the time self there is congestion state in discovery, the definite process that need to carry out load balancing.
Step 402, macro base station utilizes RRC message to indicate the UE in its coverage to read the service type information of CSG community or mixed cell.Wherein, this service type information includes but not limited to: the CGI of community, access module, RSRP (Reference Signal Received Power, reference symbol received power), the non-CSG Member Users's that supports of the preliminary access inspection of RSRQ (Reference Signal Received Quality, the reference symbol quality of reception), UE, Home eNodeB COS (only effective to mixed cell).
Step 403, UE reads the SIB1 message of HeNB1 and HeNB2.
In the present embodiment, send indication information describe as example take Home eNodeB in broadcast, now, UE need to read the SIB1 message of HeNB1 and HeNB2.
Step 404, UE feeds back to macro base station by measurement report by reading result.
Wherein, this reading result is service type information above-mentioned correspondence, for example, HeNB1 and HeNB2 be all the Home eNodeB, HeNB1 of mixed mode for non-CSG Member Users supported data business, HeNB2 only supports paging service etc. for non-CSG Member Users.
Step 405, macro base station is determined the Home eNodeB that carries out follow-up load balancing.
Concrete, when receiving after measurement report, macro base station finds that HeNB1 and HeNB2 are the Home eNodeB of mixed mode, and all exists some users around, and what in these users, have belongs to CSG Member Users, and what have belongs to non-CSG Member Users.
In addition, HeNB2 can only provide paging service for non-CSG Member Users, and HeNB1 provides data service for non-CSG Member Users, and macro base station is determined and do not carried out follow-up load balancing with HeNB2, and determines and HeNB1 carries out follow-up load balancing.
Step 406, macro base station and Home eNodeB HeNB1 carry out the negotiation of power parameter, to determine the size of Home eNodeB HeNB1 Modulating Power.
The embodiment of the present invention six provides a kind of indicating means of COS, in the present embodiment, describes as an example of the interference self-optimizing process of Home eNodeB example, and wherein, this Home eNodeB is only supported paging service.As shown in Figure 5, the method comprises the following steps:
Step 501, in the time that UE finds that the signal strength signal intensity of Home eNodeB meets A3 event, that triggers UE measurement report reports and records this measurement report.Wherein, this UE is the UE of ownership macro base station, and this measurement report need to report this macro base station.
Step 502, macro base station sends RRC message and requires UE to read the system information of this Home eNodeB.
Concrete, when macro base station receives after this measurement report, if find that the PCI of this Home eNodeB belongs to the scope of hybrid base station, macro base station need to send RRC message and requires UE to read the system information of this Home eNodeB.
Step 503, UE reads the system information of this Home eNodeB.
Concrete, when UE receives after RRC message, the SI information (being system information) of this Home eNodeB be need to read, and CSG ID, the ECGI of this Home eNodeB, the information such as COS and pre-access inspection of blended family base station obtained.
Further, because this Home eNodeB is only supported paging service (COS of blended family base station is paging service), the COS that therefore in SIB1 message, non-CSG Member Users supports is 0 (by using 0 expression paging service).
In addition, UE finds that the CSG ID of this Home eNodeB is not within its Allowed CSG List scope, and UE judges and oneself belongs to non-CSG Member Users.
Step 504, UE crosses RRC message report to macro base station by above-mentioned information exchange.
Step 505, macro base station receives after RRC message, finds that this UE belongs to non-CSG Member Users and family service is only supported to seek to non-CSG Member Users in Target cell, determines and does not carry out handoff procedure.
Step 506, the adjustment of macro base station transmitted power is indicated to Home eNodeB.Wherein, this power adjustment indication interference to grand UE around for reducing Home eNodeB.
Concrete, when macro base station counts on after the measurement report that multiple UE report within a period of time, the RSRQ of the macrocell that discovery UE reports is lower than thresholding TH (this parameter can be determined by the demand of emulation or operator), macro base station thinks that Home eNodeB is excessive near the interference of macro base station, and because Home eNodeB belongs to mixed cell and only supports paging service, macro base station need to send a power adjustment and indicates to Home eNodeB, this power adjustment indication interference to grand UE around for reducing Home eNodeB.
The embodiment of the present invention seven provides a kind of indicating means of COS, in the present embodiment, describe as an example of the interference self-optimizing process in Hierarchical Network example, wherein, in network, have the Home eNodeB of a macro base station and a mixed mode, this Home eNodeB is initially to non-CSG Member Users supported data business.It should be noted that the blended family base station of non-CSG Member Users only being supported to paging service, macro base station thinks that the interference coordination strategy that it is adopted is identical with the Home eNodeB of closed mode.As shown in Figure 6, the method comprises the following steps:
Step 601, Home eNodeB is periodically added up the load of self.
Step 602, Home eNodeB is adjusted non-CSG Member Users's COS.
Concrete, periodically add up in the process of self loading at Home eNodeB, if this Home eNodeB is in the time that non-CSG Member Users's the load of finding sometime self exceedes a default thresholding, this Home eNodeB is thought non-CSG Member Users overload, and Home eNodeB need to be adjusted non-CSG Member Users's COS.
In the embodiment of the present invention, take Home eNodeB by non-CSG Member Users's COS by providing data service to be adjusted to only to provide paging service to describe as example.
Step 603, Home eNodeB is revised the related content in broadcast, and sends ENB CONFIGURATION UPDATE message to the macro base station that has X2 to connect.
Concrete, Home eNodeB need to be revised as the related content in broadcast: Home eNodeB to non-CSG Member Users's COS for paging service is provided.And in ENB CONFIGURATIONUPDATE message, carried Home eNodeB to non-CSG Member Users's COS for the IE of paging service is provided.
