Embodiment
The problem of the too complicated and high cost of the UE that causes in view of the gravity treatment of prior art small area is unreachable or signaling traffic load is excessive and cause due to integrated UA Home eNodeB HNB, the embodiment of the present invention provides a kind of method that realizes IMS speech business from Home eNodeB HNB, when UE is attached to Home eNodeB HNB, allow the customer traffic of UE directly from Home eNodeB HNB or femto gateway HNB GW, route to destination entity, without mobile core network, the resource consumption of minimizing to mobile core network, also reduce user's rate simultaneously, allow the chain of command signaling of UE still pass through mobile core network, HNB too complexity and the excessive problem of signaling traffic load have been avoided.
In the technical scheme that the embodiment of the present invention provides, the address that Home eNodeB or femto gateway are provided and port notice IMS territory; The address that IMS territory is provided and port notice Home eNodeB or femto gateway; Between Home eNodeB or femto gateway and IMS territory, directly set up carrying, if follow-up IMS field communication opposite end medium surface upgrades, MSC server is notified HNB or HNB GW.From femto gateway, directly to the carrying in IMS territory, set up mode and have two kinds: one, MSC server, by femto gateway as base station controller RNC, controls it by Iu-CS interface and sets up carrying; Two, MSC server, by femto gateway as media gateway MGW, controls it by Mc interface and sets up carrying.When UE accesses from HNB, chain of command is via MSC server access IMS, and user's face is routed directly to destination entity from HNB or HNB GW, the bypass of user's face mobile core network, be that Media Stream is routed directly to IMS field communication opposite end from HNB, avoided mobile core network.
Particularly, UE does when called, and MSC server receives and respond request message this UE of paging that calls out UE from IMS territory, the medium surface information that this message comprises IMS territory, also referred to as Session Description Protocol (SDP, Session Description Protocol) information; The user equipment (UE) that is attached to HNB is responded after paging, and (the so-called message that sends refers to that to HNB message is through HNB GW, but HNB GW just simply passes to HNB to HNB or HNB GW to send load-bearing allocation message; The so-called message that sends refers to that to HNB GW message is through HNB GW, and it is processed this message and is established to the carrying of media gateway, then it sends and sets up bearer messages to HNB, be established to the carrying of HNB, this saying is applicable in full), and use address and port in the medium surface information SDP in described IMS territory to set up carrying; HNB or HNB GW distribute address and port transmission carrying to set up response message to MSC server, and address and port and IMS field communication opposite end negotiating bearer that MSC server adopts HNB or HNB GW to distribute, to set up calling.If follow-up IMS field communication opposite end medium surface upgrades, MSC server notifies HNB or HNB GW.Or UE does when called, MSC server is using HNB GW as MGW, sends the address of IMS field communication opposite end and port to HNB GW and allows HNB GW prepare carrying, and HNB GW provides address and port, this and opposite end negotiation medium surface for MSC server.
When UE does caller, MSC server first makes a call to IMS field communication opposite end with empty address and port, IMS field communication opposite end is responded after media information, by load-bearing allocation message, send to HNB or HNB GW, HNB or HNB GW respond address and the port of oneself, MSC server initiates to IMS field communication opposite end with this to upgrade, and completes bearer negotiation.When UE does caller, also can be by MSC server using HNB GW as media gateway and allow HNB GW prepare carrying, then the address providing with HNB GW and port make a call to IMS field communication opposite end as carrying, IMS field communication opposite end is responded after media information, and MSC server tells HNB GW by the address of IMS field communication opposite end and port.
When UE is switched to HNB from macro base station, what MSC server carried IMS field communication opposite end in handover request message gives HNB or HNB GW (requiring MSC server to preserve address and the port of IMS field communication opposite end), HNB or HNB GW return to address and the port of distribution, MSCserver with this address and port to IMS field communication opposite end new bearer more.Or when UE is switched to HNB from macro base station, by MSC server, using HNB GW as MGW and allow HNB GW prepare carrying, MSC server carries out medium surface renewal with this address and port to IMS field communication opposite end;
When UE is switched to macro base station from HNB, MSC server selects a MGW, allows MGW prepare carrying, and MGW provides address and port, and MSC server carries out medium surface renewal with this and IMS field communication opposite end; MSC server allows MGW prepare another carrying, and MGW provides address and port, carries this address and port to HNB or HNB GW in handover request message, and HNB or HNB GW return to address and the port of distribution.
Like this, can be by circuit domain voice call transfer to IMS territory, without in picture prior art on each HNB integrated UA, reduced HNB complexity and cost; And when switching, UE can keep continuity.
