Specific implementation mode
If the source HeNB and target HeNB that execute handover operation are connected on the same HeNB GW, such as Fig. 3 institutes
Show, since HeNB GW do not change later in switching, the user's context in HeNB GW is to be not necessarily to release, because
This, at this point, source HeNB is need not to send the user's context release comprising GW contexts release indication information element to HeNBGW to ask
Seek message.It is connected under the scene of the same HeNB GW since most of X2 switchings are happened at source and target HeNB, that
If the user's context for discharging indication information element comprising GW contexts of a large amount of redundancy can be caused according to the operation of step 204
Discharge the transmission of request message.
To solve the above-mentioned problems, the embodiment provides a kind of home base station gateway user equipment contexts to release
Method and system is put, can be made in source Home eNodeB (being specially source HeNB) and target household base station (being specially target HeNB)
It is under the scene being connected on the same home gateway (being specially HeNB GW), source HeNB does not send the band of redundancy to HeNB GW
The user's context release request message for having GW contexts release indication information element, effectively reduces S1 signaling overheadss, alleviates
Processing load, to improve system performance.
The embodiment of the present invention is described in detail below in conjunction with attached drawing.It should be noted that not conflicting
In the case of, the features in the embodiments and the embodiments of the present application mutually can be combined arbitrarily.
According to the standard of existing Release 10, after UE is switched to target HeNB from source based on X2, as long as source HeNB is
It is connected on HeNB GW, no matter whether target HeNB is connected on HeNBGW, source HeNB will be sent with GW contexts
The user's context release request message of release indication information element to HeNB GW come trigger HeNB GW release switching UE up and down
Text.But when source and target is connected under the scene of the same HeNB GW, completed from source HeNB to target HeNB's in UE
After switching, HeNB GW need not discharge the context of switching UE, the band sent to HeNB GW then existing source HeNB remains unchanged
The user's context release request message that GW contexts discharge indication information element is redundancy.In the embodiment of the present invention, HeNB
GW is established in source HeNB and target HeNB in the TNL address discovery process of direct X2 interface, in transmission configuration message, by its with
Source HeNB and target HeNB establishes the instruction letter whether the source and target HeNB known when S1 interfaces is connected to the same HeNB GW
Breath informs source and target HeNB.After UE is switched to target HeNB from source HeNB based on X2, source HeNB connects according to from HeNB GW
The instruction information received decides whether that sending user's context to HeNB GW discharges request message.If source HeNB is received
Source and target HeNB is the instruction information for being connected to the same HeNB GW, then source HeNB does not send user's context to HeNB GW
Discharge request message；If it is the instruction information for being connected to the same HeNB GW that source HeNB, which is not received by source and target HeNB,
Then source HeNB sends user's context release request message to HeNBGW.If establishing the TNL of direct X2 interface between two HeNB
Address is configured by OAM, then the instruction information whether two HeNB can also be connected to the same HeNB GW by OAM is accused
Know source and target HeNB.If OAM will only indicate that information tells one in two HeNB, can lead between two HeNB
It crosses X2 and establishes process to interact instruction information.
The present invention is further described in more detail with reference to the accompanying drawings and embodiments.
First, the embodiment of the present invention one is illustrated.
It is connected on the same HeNB GW if the embodiment of the present invention mainly describes two HeNB,
HeNB GW just pass through the configuration in transport network layer (Transport Network Layer, abbreviation TNL) address discovery process
Transmission message will indicate that information informs the two HeNB.This stores HeNB the instruction information of acquisition respectively.Later when switching is sent out
When life is between the two HeNB, the instruction information that source HeNB is sent based on the HeNB GW received decides not to send user
Context release request message is to HeNB GW.
Fig. 4 is the flow diagram of the present embodiment.Wherein, source Home eNodeB HeNB1 and target household base station HeNB2 is to connect
It is connected under the same femto gateway HeNB GW1.
As shown in figure 4, the detailed process of the present embodiment mainly includes the following steps：
Step 401：HeNB1 passes through automatic neighborhood (Automatic Neighbour Relation, abbreviation ANR)
Function knows Base Station Identification (eNB ID) HeNB2ID of HeNB2, but HeNB1 does not know and establishes SCTP (Stream with HeNB2
Control Transmission Protocol) connection the addresses TNL, then HeNB1 can utilize configuration transfer function
(Configuration Transfer Function) determines the addresses TNL of HeNB2.HeNB1 sends eNB configuration transmission
(eNB Configuration Transfer) message comes the addresses TNL of acquisition request HeNB2 to HeNB GW1.It is configured in eNB
Transmission message includes the relevant information of source and target HeNB, such as HeNB1ID, TAC1 (Tracking Area Code),
HeNB2ID, TAC2.
Step 402：When HeNB GW1 and HeNB1 and HeNB2 points of ratios establish S1 interfaces, HeNB GW1 are known
HeNB1 and HeNB2 are connected to below it.Then HeNB GW1 add in the MME configuration transmission message for being sent to HeNB2
Instruction information is added.The instruction information is used to refer to whether HeNB1 and HeNB2 is to be connected on HeNB GW1 based on S1 interfaces
's.HeNB2 preserves the instruction information.
Step 403：HeNB2 responds the request of HeNB1, and the eNB configuration transmission for sending the addresses TNL with SCTP connections disappears
Cease HeNB GW1.
Step 404：As step 402, it is to know HeNB1 and HeNB2 all and be to connect that HeNB GW1 establish process by S1
Be connected below it, then HeNB GW1 be sent to HeNB1 MME configuration transmission message in be added to be connected to it is same
Instruction information on HeNB GW.HeNB1 preserves the instruction information.
Step 405-406：When UE from HeNB1 to HeNB2 based on direct X2 switch prepare and implementation procedure after the completion of,
HeNB2 transmitting pathes transition request message gives HeNB GW1, HeNB GW1 to forward the message to MME.
Step 407-408：MME transmitting path convert requests confirmation messages give HeNB GW1, HeNBGW1 to forward the message to
HeNB2。
Step 409：HeNB2 sends user's context release message and has been switched successfully to HeNB1 to trigger HeNB1 releases
UE context.
Step 410：The UE contexts of HeNB1 release switchings.
Step 411：It is same that HeNB1 judges whether that the instruction source and target HeNB for receiving HeNB GW1 transmissions is connected to
The information of HeNB GW.Because HeNB1 has received the instruction information for being connected to the same HeNB GW that HeNB GW1 are sent, because
This HeNB1 decides not to send user's context release request message and gives HeNB GW1.
In the following, being illustrated to the embodiment of the present invention two.
It is not connected on the same HeNBGW if the embodiment of the present invention mainly describes two HeNB,
HeNB GW will not include in the configuration transmission message for being sent to two HeNB in TNL address discovery process any source and
Target is the instruction information being connected on the same HeNB GW.Later when switching is happened between the two HeNB, source
HeNB is the instruction information for being connected to the same HeNB GW because of being not received by any about source and target, to still send out
The user's context for discharging indication information element with GW contexts is sent to discharge request message to HeNB GW to trigger on HeNB GW
The UE contexts of switching discharge.
Fig. 5 is the flow diagram of the present embodiment.Wherein, Home eNodeB HeNB1 in source is to be connected to femto gateway
Under HeNB GW1, target household base station HeNB2 is direct-connected at MME.
As shown in figure 5, the detailed process of the present embodiment mainly includes the following steps：
Step 501：HeNB1 sends the addresses TNL that eNB configuration transmission message carrys out acquisition request HeNB2 to HeNB GW1.
ENB configuration transmission message includes the relevant information of source and target HeNB, such as HeNB1ID, TAC1 (Tracking Area
Code), HeNB2ID, TAC2.
Step 502：HeNB GW1 are by forwarding eNB configuration transmission message.
Step 503：MME relays the request of HeNB1 by sending MME configuration transmission message to HeNB2.
Step 504-505：HeNB2 sends the request that eNB configuration transmission message responds HeNB1 to MME.Match in the eNB
It includes the addresses TNL being connect with the HeNB1 SCTP established to set in transmission message.MME by send MME configuration transmission message to
HeNB GW1 relay response message.
Step 506：HeNB GW1 relay the response message of HeNB2 by sending MME configuration transmission message to HeNB1.
Since HeNB GW1 know that HeNB2 is not all connected to below it during S1 is established, HeNB GW1 are not at this
Any instruction information is added in MME configuration transmission message.
Step 507-508：When UE from HeNB1 to HeNB2 based on direct X2 switch prepare and implementation procedure after the completion of,
HeNB2 transmitting pathes transition request message gives HeNB GW1, HeNB GW1 to forward the message to MME.
Step 509-510：MME transmitting path convert requests confirmation messages give HeNB GW1, HeNBGW1 to forward the message to
HeNB2。
Step 511：HeNB2 sends user's context release message and has been switched successfully to HeNB1 to trigger HeNB1 releases
UE context.
Step 512：The UE contexts of HeNB1 release switchings.
Step 513：It is same that HeNB1 judges whether that the instruction source and target HeNB for receiving HeNB GW1 transmissions is connected to
The information of HeNB GW.Since HeNB1 is not received by any instruction information that HeNB GW1 are sent, HeNB1 decisions remain unchanged
It sends the user's context with GW contexts release indication information element and discharges request message to HeNB GW1.
Step 514：HeNB1 send with GW contexts release indication information element user's context release request message to
HeNB GW1。
Step 515：The UE contexts of HeNB GW release switchings.
In the embodiment of the present invention one and embodiment two, if source and target HeNB is to be connected to the same HeNB GW
On, then HeNB GW then send corresponding instruction information；If source and target HeNB is connected on the same HeNB GW,
So HeNB GW do not send any relevant instruction information then.Certainly, whether source HeNB and target HeNB is connected to same
On HeNB GW, it can also be notified using specific representative instruction information.If source and target HeNB is to be connected to
On the same HeNB GW, then HeNB GW are then sent, to represent source and target HeNB be the finger being connected on the same HeNB GW
Show information；If source and target HeNB is connected on the same HeNB GW, HeNB GW then send and represent source and mesh
It is not the instruction information being connected on the same HeNB GW to mark HeNB.Whether any indicating means, source and target HeNB is
The related instruction information of storage, for the subsequent judgement for whether sending user's context release request.
