Background technology
Realease9 HeNB (Home eNodeB, the Home eNodeB of evolution) in support IP (Internet Protocol has been proposed, Internet Protocol) UE (User Equipment, subscriber equipment) of ability can access by HeNB the demand of home network.Fig. 1 is the network architecture of the E-UTRAN (Evolved Universal Terrestrial Radio Access Network, evolved universal terrestrial radio access network) that comprises HeNB GW (Gateway, gateway).Between eNB, connect by X2 interface, between eNB and MME (Mobile Management Entity mobile management entity), connect by S1 interface.If HeNB, can directly be connected with MME (example is HeNB1 as shown in Figure 1), also can be linked into MME (example is HeNB2 and HeNB3 as shown in Figure 1) by a centralized node HeNB GW, between HeNB, there is no interface, between HeNB and grand eNB, also there is no interface, HeNB can only be connected with a HeNB GW simultaneously.The lower affiliated subdistrict of grand eNB (macro eNB) is macrocell (macro cell), and under HeNB, affiliated subdistrict is CSG (Closed Subscriber Group, internal user group) community.
Can find out, between HeNB and HeNB, or do not have X2 interface to be connected between HeNB and eNB, between grand eNB and grand eNB, can not ensure necessarily to have in addition X2 interface to be connected, therefore in the situation that there is no X2 interface, cannot use X2 interface to transmit inside of base station information.And handover request message on S1 interface need to be filled in target ID, need to distinguish grand eNB and HeNB.Macro eNB is 20bits, and HeNB is 28bits.In this case, before switching, if source base station can not be known the attribute information of target BS, just can not ensure to send correct handover request information.
In current Release8 release protocol, also distinguishing cell access module is being eated dishes without rice or wine to broadcast by the CSG indication bit (csg-Indication) in system information (SystemInformationBlockType1) and CSG mark (csg-identity) in base station.Wherein: the Boolean type indication information that CSG indication bit (csg-Indication) is 1bit, is used to indicate whether ShiCSG community, Xia community, base station.The character string that CSG mark (csg-Identity) is 27bit, is divided into and can occurs and not occur two kinds of modes (OPTIONAL).
One example of the system information (SystemInformationBlockType1) in Release8 release protocol is as follows:
SystemInformationBlockType1::＝ SEQUENCE{
cellAccessRelatedInfo SEQUENCE{
plmn-IdentityList PLMN-IdentityList，
trackingAreaCode TrackingAreaCode，
cellIdentity CellIdentity，
cellBarred ENUMERATED{barred，notBarred}，
intraFreqReselection ENUMERATED{allowed，notAllowed}，
csg-Indication BOOLEAN，
csg-Identity BIT STRING(SIZE(27))OPTIONAL
}，
…
}
In Release8 release protocol:
In the time that CSG indication bit (csg-Indication) occurs for " TRUE " and CSG mark (csg-Identity), show WeiCSG community, Xia community, base station;
In the time that CSG indication bit (csg-Indication) does not occur for " FALSE " and CSG mark (csg-Identity), show that Xia community, base station is macrocell (macro cell);
When CSG indication bit (csg-Indication) for " TRUE " but when CSG mark (csg-Identity) does not occur, be illegal abnormal conditions;
When CSG indication bit (csg-Indication) for " FALSE " but when CSG mark (csg-Identity) occurs, be illegal abnormal conditions.
In Release9 release protocol, under HNB/HeNB, there is San Zhong community access module, be respectively:
Open mode (Open access mode): open mode CSG community, operates similar macrocell as normal cell (normal cell).
Closed mode (Closed access mode): closed mode CSG community, operates as CSG community.
Mixed mode (Hybrid access mode): mixed mode CSG community, although ShiCSG community also allows non-CSG member's access simultaneously.
ENB or HeNB as source base station pass through ANR (Automatic Neighbor Relationship, Automatic Neighboring Relation) safeguard neighboring BS relationship, in the time that UE switches, source base station need to know that the adjacent cell under target BS is macrocell or CSG community.But problems of the prior art are, in the Release8 release protocol using at present, can not before switching, make source base station know the information of the access module of adjacent cell, thereby can not ensure that source base station sends correct handover request information to the target BS of adjacent cell; In addition, do not support the instruction to community access modules such as open mode CSG community and mixed mode CSG communities.

Concrete, the present invention can, by the community access module sign of following three kinds of modes is provided, can distinguish macrocell, open mode CSG community, closed mode CSG community and mixed mode CSG community:
(1) access module sign in community specifically comprises CSG indication bit and CSG mark, by the various combination of CSG indication bit and CSG mark, macrocell, open mode CSG community, closed mode CSG community and mixed mode CSG community are distinguished.
(2) access module sign in community is specially the CSG indication bit after expansion, by the different value of the CSG indication bit after expansion, macrocell, open mode CSG community, closed mode CSG community and mixed mode CSG community are distinguished.
(3) access module sign in community is specially the CSG access module indication bit outside CSG indication bit and CSG mark, by the different value of CSG access module indication bit, macrocell, open mode CSG community, closed mode CSG community and mixed mode CSG community are distinguished.
Below in conjunction with concrete application scenarios, above-mentioned three kinds of modes are elaborated one by one.
In first application scenarios of the present invention, specifically comprise that with community access module sign CSG indication bit and CSG are designated example, describe the embodiment by CSG indication bit (csg-Indicatoion) and the various combination pattern of CSG mark (csg-Identity) are distinguished community access module.
In Release8 release protocol, determine in the time that CSG indication bit (csg-Indication) occurs for " TRUE " and CSG identify (csg-Identity), show that Xia community, base station is closed CSG community; In the time that CSG indication bit (csg-Indication) does not occur for " FALSE " and CSG mark (csg-Identity), show that Xia community, base station is macrocell (macro cell); When CSG indication bit (csg-Indication) for " TRUE " but when CSG mark (csg-Identity) does not occur, be illegal abnormal conditions; When CSG indication bit (csg-Indication) for " FALSE " but when CSG mark (csg-Identity) occurs, be illegal abnormal conditions.
In the network of Release9 release protocol, need to support the mixed mode or not in Release8, and need to distinguish open mode (Open access mode) CSG community and macrocell (macro cell).For compatibility is used the UE of Release8 release protocol, network need to be distinguished not changing these two message structures and big or small prerequisite Xia Dui community access module.
To this, the invention provides the indicating means of following community access module:
In the time that CSG indication bit (csg-Indication) does not occur for " FALSE " and CSG mark (csg-Identity), represent that this community is macrocell (macro cell);
In the time that CSG indication bit (csg-Indication) occurs for " TRUE " and CSG mark (csg-Identity), represent that this community is closed mode (Closed access mode) CSG community;
In the time that CSG indication bit (csg-Indication) occurs for " FALSE " and CSG mark (csg-Identity), can represent that this community is mixed mode (Hybrid access mode) CSG community;
In the time that CSG indication bit (csg-Indication) does not occur for " TRUE " and CSG mark (csg-Identity), can represent that this community is open mode (Open access mode) CSG community.
Above-mentioned CSG indication bit (csg-Indicatoion) is only for example from the CSG mark various combination pattern of (csg-Identity) and the corresponding relation of different access modules, be understandable that, above-mentioned corresponding relation is not limited to the description in the present embodiment.In this way, can, by the various combination pattern access module of indicating cell in the information of eating dishes without rice or wine clearly of CSG indication bit (csg-Indicatoion) and CSG mark (csg-Identity), facilitate UE to read.
In second application scenarios of the present invention, be specially CSG indication bit (csg-Indicatoion) after expansion as example taking community access module sign, describe by the different value of the CSG indication bit after expansion, the embodiment that community access module is distinguished.
In Release8 protocol version, the length of CSG indication bit (csg-Indicatoion) is 1bit, can not represent three kinds of access modules.Therefore, in the present invention, this CSG indication bit (csg-Indicatoion) is expanded to the character string type of 2bit, can indicate three kinds of CSG cell patterns and macrocell pattern.For example, one of the system information structure after expansion for example under:
SystemInformationBlockType1::＝ SEQUENCE{
cellAccessRelatedInfo SEQUENCE{
plmn-IdentityList PLMN-IdentityList，
trackingAreaCode TrackingAreaCode，
cellIdentity CellIdentity，
cellBarred ENUMERATED{barred，notBarred}，
intraFreqReselection ENUMERATED{allowed，notAllowed}，
csg-Indication BIT STRING(SIZE(2))，
csg-Identity BIT STRING(SIZE(27))OPTIONAL
}，
…
}
By the CSG indication bit (csg-Indicatoion) of 2bit, can indicate different community access modules.For example:
Because csg-Indication forces to occur in system information, for the macrocell (macro cell) that does not need CSG ID, can use csg-Indication=" 00 " to represent so;
For closed mode (Closed access mode) CSG community, can use csg-Indication=" 11 " to represent, and the content of instruction csg-Identity;
For open mode (Open access mode) CSG community or mixed mode (Hybridaccess mode) CSG community, can use remaining two kinds of value csg-Indication=" 01 " and csg-Indication=" 10 " to represent respectively.
Above-mentioned CSG indication bit (csg-Indicatoion) value is only for example from the corresponding relation of different access modules, is understandable that, above-mentioned corresponding relation is not limited to the description in the present embodiment.In this way, can, by CSG indication bit (csg-Indicatoion) access module of indicating cell in the information of eating dishes without rice or wine clearly of expansion, facilitate UE to read.
In the 3rd application scenarios of the present invention, be specially community access module sign taking community access module sign and be specially CSG access module indication bit outside CSG indication bit and CSG mark as example, the embodiment that community access module is distinguished is described by the different value of CSG access module indication bit.
In Release8 protocol version, the length of CSG indication bit (csg-Indicatoion) is 1bit, can not represent three kinds of access modules.For compatible Release8 protocol version, in the present invention, in system information, increase community access module sign (csg-AccessMode), length is 2bit, for indicating separately three kinds of CSG cell patterns and macrocell pattern.For example, one of the system information structure after expansion for example under:
SystemInformationBlockType1::＝ SEQUENCE{
cellAccessRelatedInfo SEQUENCE{
plmn-IdentityList PLMN-IdentityList，
trackingAreaCode TrackingAreaCode，
cellIdentity CellIdentity，
cellBarred ENUMERATED{barred，notBarred}，
intraFreqReselection ENUMERATED{allowed，notAllowed}，
csg-Indication BOOLEAN，
csg-Identity BIT STRING(SIZE(27))OPTIONAL
}，
…
v9NonCriticalExtension SEQUENCE{
csg-AccessMode BIT STRING(SIZE(2))，
nonCriticalExtension SEQUENCE{} OPTIONAL
--Need OP
} OPTIONAL--Need OP
}
By the community access module sign (csg-AccessMode) of 2bit, can indicate different community access modules.Such as:
For macrocell (macro cell), can use csg-AccessMode=" 00 " to represent;
For closed mode (Closed access mode) CSG community, can use csg-AccessMode=" 11 " to represent;
For open mode (Open access mode) CSG community or mixed mode (Hybridaccess mode) CSG community, can use remaining two kinds of value csg-AccessMode=" 01 " and csg-AccessMode=" 10 " to represent respectively.
Above-mentioned community access module sign (csg-AccessMode) value is only for example from the corresponding relation of different access modules, is understandable that, above-mentioned corresponding relation is not limited to the description in the present embodiment.In this way, can, by community access module sign (csg-AccessMode) access module of indicating cell in the information of eating dishes without rice or wine clearly, facilitate UE to read.
