Description
Technical field
The present invention relates to mobile communication technology, the sub-district handoff technique in particularly a kind of LTE (Long Term Evolution, Long Term Evolution) system.
Background technology
Present mobile communication more and more trends towards providing the high-speed transfer multimedia service, and the birth of HeNB in the LTE system (Home eNodeB, family base station) has effectively improved system and experienced in the transmission of covering, throughput and the indoor user of hot zones.
Different with the base station of traditional cellular communication, family base station be a kind of small-sized, can be installed in base station indoor, flexible configuration.Have statistics to show, for multimedia service at a high speed, broadband services more applications scene is indoor and hot zones.Adopt traditional cellular mobile communication mode then to the support deficiency of this type of demand.The birth of family base station just for solve such contradiction, offer need multimedia service indoor user with better user experience.
Introduced the LTE system of family base station, consistent basically with the LTE system that does not dispose family base station on the network configuration of integral body, but volume is little, Installation Flexibility is high because family base station need possess, the communication relative complex between the corresponding family base station.Fig. 1 is E-UTRAN (Evolution-UMTS Territorial Radio Access Network UMTS, the land radio access web of evolution system) comprises HeNB GW (Home eNB Gateway, family base-station gateway) the network architecture, main operational module has HeNB, HeNB GW, and MME (Mobility Management Entity, mobile management module).
Being X2 interface between the eNB, is the S1 interface between eNB and the MME, and MME and S-GW are logical nodes, and S-GW and MME can merge and be set to an entity, also can separately be set to two independent entity.Can directly connect between HeNB and the MME, also can be linked into MME by a centralized node HeNBGW, not have interface between the HeNB, HeNB can only link to each other with a HeNB GW, and difference connects a plurality of HeNB GW simultaneously.
Since HeNB towards be similar application scenes such as family, small enterprise, therefore HeNB equipment may be had by the user, requires the HeNB system whether to provide service according to the user identity decision naturally, promptly possesses access control function.For example, certain user and certain operator contract and at oneself HeNB are installed, and this user wishes that HeNB only provides service to kinsfolk and some specific visiting guests etc.At this requirement of HeNB, 3GPP propose to adopt the control that conducts interviews of the notion of CSG (Closed Subscriber Group, closed user group) at the Release8 version.CSG refers to a group contracted user who allows to insert one or more specific cells, one or more sub-districts here are limited, with good conditionsi when inserting the user, and the normal cellular sub-district can allow all legal contracted users (and roamer) of operator to insert.And same user can belong to a plurality of CSG, each CSG is identified by a CSG ID, UE safeguards the CSGID tabulation of a CSG under it, the CSG ID tabulation (Allowed CSG List) that promptly allows, the CSG sub-district that other CSG ID outside this Allowed CSG List are comprised is an inaccessible for this UE.And CSG ID of each CSG Cell Broadcast CB, the member of the closed user group that this CSG ID is identified can visit this sub-district.Therefore in this case, UE inserts and when switching, need carry out the CSG access control initial, and UE only can select to allow the CSG sub-district inserted, simultaneously, MME also needs to check to guarantee that UE can illegally not insert not the sub-district of Allowed CSG list to one's name.
There are three kinds of access modules the sub-district of HeNB, comprise closed mode (Close Mode), open mode (Open Mode) and mixed mode (Hybrid Mode), Close Mode is meant and only allows the UE that comprises this sub-district CSG ID among the AllowedCSG List to insert; Hybrid mode is meant that HeNB allows all UE to insert sub-districts, no matter whether comprises the CSG ID of this sub-district among the Allowed CSG List of UE; And Open Mode is meant that the sub-district does not have CSG ID, allows all UE to insert.
When UE switches between two eNB, need utilize the handoff procedure on the S1 interface, the process of switching by the S1 interface in the agreement comprises the switching set-up procedure and switches the resource needed assigning process at present, wherein switches set-up procedure as shown in Figure 2, comprises the steps:
When residing source eNB determined that UE need switch before 1, UE switched, send handoff request (HANDOVER REQUIRED) to the serving MME (Serving MME) that connects;
2, Serving MME and target eNB are carried out alternately, and after target eNB is ready to switch, MME will send switching command (HANDOVER COMMAND) message to source eNB.
Handover resource allocation procedure comprises the steps: as shown in Figure 3
1, MME is by sending handoff request (HANDOVER REQUEST) message to target eNB;
2, confirm to be E-RAB (the E-UTRAN Radio Access Bearer:E-UTRAN that accepts when target eNB, RAB) after the resource that distribution is necessary, sends Handover Request Acknowledge (HANDOVER REQUEST ACKNOWLEDGE) message to MME.
The inventor finds, do not provide the control technology that UE switches in the prior art between the different districts under the same HeNB.
