Embodiment
At also there not being the ambulant scheme of a kind of support LIPA at present, the core network control node of the embodiment of the invention is received from the request of source Home eNodeB and is switched message, and definite subscriber equipment activates the LIPA carrying, if determine to keep after subscriber equipment activation LIPA is carried on switching, then discharge the LIPA carrying.During owing to switch, after the LIPA that determines the subscriber equipment activation is carried on switching, can not keep, can discharge the LIPA carrying, thereby realize the LIPA mobility, improve network performance and system effectiveness.
Wherein, the contextual information that comprises the LIPA carrying in the message is switched in the request of the embodiment of the invention.Preferable, the contextual information that LIPA carrying in the message is switched in request is included among the additional container (extra vessel) that asks to switch in the message.
Additional container is for fear of RAN (the RadioAccess Network to Pre-R11 in the 3GPP SA2 meeting, wireless access network) node impacts, and evade that among the Source to Target Transparent Container that target RAN node receives the inconsistent problem of RAB quantity of RAB quantity and core-network side request proposes, concrete:
The source Home eNodeB uses two RRC container in handoff request message, wherein original Sourceto Target Transparent Container encapsulates non-LIPA carrying, and a newly-increased RRC container (being additional container) encapsulation LIPA carrying.
In force, the core network control node of the embodiment of the invention includes but not limited to a kind of in the following node:
MME (Mobility Management Entity, Mobility Management Entity), SGSN (Serving GPRS Support Node, service GPRS service node; GPRS, General Packet Radio Service, GPRS).
Below in conjunction with Figure of description the embodiment of the invention is described in further detail.
As shown in Figure 2, the method for embodiment of the invention processing LIPA carrying comprises the following steps:
Whether step 201, core network control node are switched message in the request of receiving the source Home eNodeB, and when need to determine the subscriber equipment that switches to activate the LIPA carrying, judge that LIPA that subscriber equipment has activated is carried on can keep after switching;
In force, the contextual information that comprises the LIPA carrying in the message is switched in request, and this contextual information can uniquely correspond to the LIPA carrying that subscriber equipment activates.
Wherein, core network control node is judged the mode whether the LIPA carrying can keep, and according to different situations different judgment modes is arranged, and enumerates several situations below:
Situation one, core network control node carry out based on the per CSG of subscription data and the access control of perAPN target BS, and in access control by per CSG, but, determine that LIPA is carried on to keep after switching by after the access control of per APN.
Concrete, when core network control node carries out access control based on subscription data per CSG per APN to target BS, if if the CSG ID of target side is not signatory or signatory but out of date, then represent not pass through based on subscription data per CSG, core network control node will return the switching refuse information to the source Home eNodeB;
If pass through based on subscription data per CSG, core network control node is proceeded the perAPN access control:
If the APN that LIPA connects is not included in the APN tabulation that this CSG ID allows, and is that per APN access control is not passed through yet, then core network control node is determined that LIPA is carried on and can not be kept after switching.
Preferably, since per APN access control do not passing through, determine LIPA be carried on can not keep after switching after, in the step 202, core network control node does not transmit the corresponding LIPA information of this LIPA carrying to target side.
Concrete, in the step 202, if need to change core network control node after switching, core network control node does not comprise LIPA information in Forward Relocation Request (the preceding commentaries on classics re-positioning request) message that the target core network Control Node is transmitted;
If do not need to change core network control node after switching, core network control node does not comprise LIPA information in the handoff request message of target BS transmission.
In force, core network control node does not comprise that LIPA information can be in the ForwardRelocation Request of target core network Control Node transmission message: core network control node does not comprise the additional container that contains the LIPA carrying in ForwardRelocation Request message, and the contextual information that does not comprise the LIPA carrying in Forward Relocation Request message in the carrying tabulation that needs to set up;
Core network control node does not comprise LIPA information in the handoff request message of target BS transmission: core network control node does not comprise the additionalcontainer that contains the LIPA carrying in handoff request message, and does not comprise LIPA bearer context information in the carrying tabulation that needs to set up in handoff request message.
Situation two, core network control node are after the access control of target BS by per CSG and perAPN, send the handoff request message of the contextual information that comprises the LIPA carrying to target BS, according to the target BS return information of receiving, after definite target BS can not be accepted the LIPA carrying, determining that LIPA is carried on can not keep after switching, and wherein the contextual information of LIPA carrying comprises that request switches the contextual information that comprises in the message in the handoff request message.
Concrete, in above-mentioned situation two, if core network control node is determined that LIPA is carried on and can be kept after switching, can send the handoff request message of the contextual information that comprises the LIPA carrying to target BS, core network control node will judge whether the LIPA carrying is accepted by target side according to the message that target side is returned, if accept.Then core network control node is determined that LIPA is carried on and can be kept after switching; If be not accepted, then core network control node is determined that LIPA is carried on and can not be kept after switching.
In force, judge whether target side is accepted the mode of LIPA carrying and had two kinds:
1), if comprise LIPA bearer context information in the received carrying tabulation, illustrate that then target side accepts the LIPA carrying, otherwise the LIPA carrying is not accepted in explanation;
2), if set up in the carrying tabulation of failure and comprise LIPA bearer context information, illustrate that then target side do not accept the LIPA carrying, otherwise the LIPA carrying is accepted in explanation.
Preferably, in the step 201, core network control node can judge whether target BS is macro base station after the request switching message of receiving from the source Home eNodeB, if then directly definite LIPA can not keep after being carried on and switching; If not, judge according to above-mentioned judgment mode in continuation.
Preferably, in the step 201, core network control node can judge whether target BS is the Home eNodeB of closure or mixed mode after the request switching message of receiving from the source Home eNodeB, if continue then to judge whether subscriber equipment activates the LIPA carrying; If not the Home eNodeB of closure or mixed mode then can handle this Home eNodeB according to the processing mode of source macro base station, can not keep after switching such as determining that directly LIPA is carried on.
In force, judge the type of target BS and judge whether subscriber equipment activates the LIPA carrying, and the sequential of these two judgements does not have and must concern, can select concrete judgement sequential as required.Preferably, the order that this two step recommends is: judge whether to activate LIPA earlier, if, continuing to judge the target BS type, this has only two kinds of possibilities: first kind, macro base station or open femtocell; Second kind, closure or mixed mode Home eNodeB; First kind of access control that does not need to be per CSG per APN, and LIPA can not keep; Second kind of needs done the access control of per CSG per APN, and follow-up the needs continues to judge that can LIPA keep.
In the step 202, core network control node is determining that the LIPA carrying can not keep back (comprising situation one and/or situation two definite can not keeping), and the notification gateway node discharges the LIPA carrying.
If core network control node need send switching command, preferably, core network control node definite LIPA be carried on can not keep after switching after, before sending switching command, the notification gateway node discharges LIPA and carries.
Concrete, in LTE (Long Term Evolution, the Long Term Evolution) system, core network control node discharges the LIPA carrying by PDN Disconnection (packet data network disconnection) process; At UMTS (Universal Mobile TelecommunicationSystem, universal mobile telecommunications system) in the system, core network control node discharges the LIPA carrying by PDP context Deactivation (block data protocol context deexcitation) process.
Preferably, in PDN Disconnection process or PDP Context Deactivation process, core network control node is only deleted the LIPA carrying at gateway node place, and the notification source Home eNodeB does not discharge the LIPA carrying.
Preferably, if core network control node need send switching command, then in the step 202, core network control node definite LIPA be carried on can not keep after switching after, send before the switching command, discharge LIPA and carry.
Preferably, in the step 202, core network control node discharges after the LIPA carrying, and indication source Home eNodeB discharges the LIPA carrying in switching command message.
Concrete, core network control node adds the contextual information of LIPA carrying in the carrying tabulation of the needs release in switching command message to.
As shown in Figure 3, embodiment of the invention core network control node carries out method of operating and comprises the following steps:
The LIPA carrying of step 310, core network control node deexcitation core-network side before switching command sends, and the indication source base station discharges the LIPA carrying (wherein in sending switching command, deactivating operation can walk abreast with the switching subsequent operation and carry out), process ends.
Further the solution of the present invention is described with three examples below, specifically referring to Fig. 4～Fig. 6.
Need to prove, in the example below, suppose the contextual information of LIPA carrying is included among the additional container that asks to switch in the message, the scheme that is not included among the additional container is similar with the scheme that is included among the additional container, does not repeat them here.
As shown in Figure 4, target BS is that the method for Home eNodeB comprises the following steps: in the embodiment of the invention LTE system
Suppose in the LTE system that target BS is a Home eNodeB, its CSG ID is signatory, but can not be inserted by this CSG sub-district according to subscription data LIPAAPN; It is constant to switch the back core network control node.
Step 401, source Home eNodeB send HO Required message to MME, wherein comprise additionalcontainer;
Step 402, MME are determining that terminal has activated the LIPA carrying in the HO Required message, and after target BS is the Home eNodeB of closure or mixing, to carry out per CSG per APN access control to target BS, according to signatory, LIPA APN can not be inserted by this CSG sub-district, and MME will not transmit LIPA carrying and additional container to target BS;
Step 403, MME send HO Request message to the target Home eNodeB, wherein do not comprise additional container, and also do not comprise the LIPA carrying among the ERABs to be Setup List (insert radio bearer and set up tabulation);
Step 404, target Home eNodeB return HO Request ACK (affirmation) message;
Step 405, MME initiate LIPA core net deleting load-bearing process;
Wherein, this step operation can be after step 402 be finished, and any time before step 406 beginning carries out, and does not have inevitable sequencing with step 403 and step 404;
Step 406, MME send HO Command (order) message to source base station, and comprise the LIPA carrying among the ERABs to Release List therein (inserting the carrying tabulation that radio bearer need discharge).
To sum up, because MME does not transmit the relevant information of any LIPA carrying to the target side base station, so Resources allocation can not carried for LIPA in the target side base station.After the switching, subscriber equipment can discharge the LIPA carrying, and source LIPA is carried in the handoff procedure by MME initiation deletion.
As shown in Figure 5, target BS is that the method for macro base station comprises the following steps: in the embodiment of the invention LTE system
Suppose in the LTE system that target BS is a macro base station; Switch the back core network control node and change, and the source core net node adopts the method for optimizing.
Step 501, source Home eNodeB send HO Required message to MME, wherein comprise additionalcontainer;
Step 502, because target BS is a macro base station, also be that LIPA is carried on and can not keeps after switching, so MME does not transmit LIPA carrying and additional container to target MME in Forward Relocation Request message;
Step 503, target MME send HO Request (handoff request) message to target BS, wherein do not comprise additional container, and also do not comprise the LIPA carrying among the ERABs to be Setup List;
Step 504, target Home eNodeB return HO RequestACK (Handover Request Acknowledge) message;
Step 505, target MME send Forward Relocation Response (response) message to source MME;
Step 506, MME send HO Command (switching command) message to source base station, and comprise the LIPA carrying among the ERABs to Release List therein.
Wherein, source MME can initiate LIPA load bearing deactivation process between step 502～step 506, and does not have inevitable sequential relationship between step 503～step 505.
To sum up, because source MME does not transmit the relevant information of any LIPA carrying to target MME, so Resources allocation can not carried for LIPA in the target side base station.After the switching, subscriber equipment can discharge the LIPA carrying.
As shown in Figure 6, target BS is that the method for Home eNodeB comprises the following steps: in the embodiment of the invention UMTS system
Suppose that in the UMTS system, target BS is a Home eNodeB; Target BS can pass through per CSG perAPN access control, but belongs to different LHN with source base station; It is constant to switch back core network control node SGSN.
Step 601, source Home eNodeB send Relocation Required (re-positioning request) message to MME, wherein comprise additional container;
Step 602, SGSN carry out per CSG perAPN access control, based on subscription data, and the access control success;
Step 603, because access control success, SGSN sends Relocation Request to target BS, wherein comprises additional container and LIPA carrying;
Step 604, target Home eNodeB are judged after receiving additional container, owing to do not belong to same LHN with source, then the target Home eNodeB is handled the LIPA carrying as not received carrying, do not comprise additionalcontainer in the Relocation Request ACK that returns (re-positioning request affirmation) message, and the LIPA carrying is included in RABs Fail to Setup (the inserting the radio bearer failure sets up) tabulation.
Step 605, because LIPA carrying is not accepted by target side, and SGSN discharges core-network side LIPA carrying, this operates in Relocation Command (reorientation order) message and finishes before sending;
Wherein, this step operation can be after step 602 be finished, and any time before step 606 beginning carries out, and does not have inevitable sequencing with step 603 and step 604;
Step 606, SGSN send Relocation Command message to the source Home eNodeB, wherein the LIPA carrying are included in RABs to be Released (the inserting radio bearer discharges) tabulation.
To sum up, when the LIPA access control is passed through,, and before switching to target side, subscriber equipment initiates to discharge because target side judges that in the time of can not keeping the LIPA carrying, the message that core network control node returns by target side is known needs to discharge the LIPA carrying.
