Description
Technical field
The present invention relates to mobile communication technology, particularly the residential quarter handoff technique in a kind of LTE system.
Background technology
Present mobile communication more and more trends towards providing the high-speed transfer multimedia service, LTE (Long TermEvolution, Long Term Evolution) HeNB of system (Home eNodeB, household base station) birth has effectively improved system and has experienced in the transmission of covering, throughput and the indoor user of hot zones.
Different with the base station of traditional cellular communication, household 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, the more application scenarios of broadband services is indoor and hot zones.Adopt traditional cellular mobile communication mode then not enough to the support of this type of demand.The birth of household base station is experienced with better user in order to solve such contradiction, offer the indoor user that needs multimedia service just.

Since HeNB towards be the similar application scenes such as family, small enterprise, therefore HeNB equipment may be had by the user, naturally requires the HeNB system to determine whether provide service according to user identity, namely 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.For this requirement of HeNB, 3GPP propose to adopt the control that conducts interviews of the concept of C SG (Closed Subscriber Group, closed user group) at the Release8 version.CSG refers to a group contracted user who allows the one or more specific cells of access, be limited, with good conditionsi during the one or more residential quarters access user here, and the normal cellular residential quarter can allow all legal contracted users (and roamer) accesses of operator.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 namely allows, the CSG residential quarter that other CSG ID outside this Allowed CSG List comprise is inaccessible for this UE.And CSG ID of each CSG Cell Broadcast CB, the member of the closed user group that this CSG ID identifies can access this residential quarter.Therefore in this case, UE need to carry out the CSG access control in initial access and when switching, and UE only can select to allow the CSG residential quarter accessed, simultaneously, MME also needs to check to guarantee that UE can illegally not access not the to one's name residential quarter of Allowed CSG list.
There are three kinds of access modules the residential quarter of HeNB, comprise closed mode (Close Mode), open mode (Open Mode) and mixed mode (Hybrid Mode), Close Mode refers to only allow to comprise among the AllowedCSG List UE access of this residential quarter CSG ID; Hybrid mode refers to that HeNB allows all UE access residential quarters, no matter whether comprises the CSG ID of this residential quarter among the Allowed CSG List of UE; And OpenMode refers to that the residential quarter does not have CSG ID, allows all UE accesses.
When UE switches between two eNB, need to utilize the handoff procedure on the S1 interface, the process of switching by the S1 interface in the agreement at present comprises to be switched set-up procedure and switches needed resource allocation process, wherein switches set-up procedure as shown in Figure 2, comprises the steps:
When residing source eNB determined that UE need to switch before 1, UE switched, send handover 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 handover 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.
