Description
Technical field
The present invention relates to radio honeycomb communication system, more specifically, in LTE base station from home deployment scenario
Under, a kind of method judging base station from home and home base-station gateway annexation and base station from home are proposed.
Background technology
Base station from home (Home eNB, HeNB) is a kind of base station small-sized, lower powered, and deployment is in
The indoor place such as front yard and office.The main advantage of base station from home is to may provide the user with higher business
Speed also reduces the expense used required for high rate services, meanwhile, makes up existing distributed cellular wireless
The deficiency that communication system covers.The advantage of base station from home is the output of economical, convenient, low-power, i.e. inserts i.e.
With etc..
Third generation partnership project (Third Generation Partnership Projects, 3GPP) pushes away
Household base station network frame in senior Long Term Evolution (Long Term Evolution, the LTE) system gone out
Structure schematic diagram is as best seen in figure 1.Wherein, HeNB based on the core network interface agreement defined in standard with
Core network element connects, and subscriber equipment (User Equipment, UE) is based on eating dishes without rice or wine defined in standard
Interface protocol accesses HeNB.To a great extent, HeNB and common macro base station (Macro eNB)
Difference is not functionally had undertaken.Based on network planning demand, under some deployment scenario, HeNB
It is also possible to between core network element mobile management entity (Mobile Management Entity, MME)
Introduce a new network element: home base-station gateway (HeNB GateWay, HeNB GW).HeNB GW
The function mainly undertaken is: the chain of command between relay forwarding and/or termination HeNB and MME and/or end
The merit of the user face data packet between knot HeNB and gateway (Serving Gateway, S-GW)
Energy；UE for access network selects service MME；Undertake the function that the paging operation of part is relevant.Figure
It is safety-related that security gateway (Security Gateway, SeGW) in 1 is used to undertake in network
Function.Base station from home management system (HeNB Management System, HeMS) mainly undertakes
Function for HeNB is managed for configuration operation.
Existing system requirements, the introducing of HeNB GW can not produce impact to existing network infrastructure,
Relevant for HeNB GW signaling, message, interactive operation etc. are required for following the principle of transparent design.Base
In the principle of transparent design, for HeNB, HeNB GW is equal to a MME, for
For MME, HeNB GW is equal to a HeNB.The incomprehensiveness existed due to HeNB GW,
HeNB cannot know that setting up the opposite end network element that S1 is connected with it is MME or HeNB GW, therefore meeting
Some signaling message in the certain operations flow process of existing network is caused to carry redundancy cell and/or in operation
Flow process occurs redundancy signaling.
Understand based on existing standard protocol status, the scene existed for HeNB GW, send out at HeNB
Need to carry the more cell of transmission in some signaling message of MME.Such as, based on LTE protocol
Standard document describes and understands, and UE completes in the operating process of switching based on X2 interface, if target BS
Be the HeNB being connected to MME by HeNB GW, then target HeNB is on the road mailing to MME
Needed to carry source MME's extraly by convert requests (PATH SWITCH REQUEST) message
Global unique identification (Globally Unique MME Identifier, GUMMEI).But, due to
HeNB GW exist incomprehensiveness, when HeNB GW not in the presence of, this cell be also required to route
Carrying transmission in convert requests signaling, i.e. cause redundancy cell carries transmission.It addition, grasp at some
In the Signalling exchange flow process made, the scene existed for HeNB GW, HeNB needs extra interpolation one
Mail to the signaling of MME a bit, the incomprehensiveness existed due to HeNB GW, do not deposit at HeNB GW
Scene under, these signalings be also required to transmission, the situation of redundancy signalling i.e. can be caused to occur.Example
As, when UE completes after source HeNB is switched to target BS based on X2 switching flow, source HeNB
Need to discharge the context letter of the UE switched away from based on the instruction message receiving target BS
Breath, if source HeNB is to be connected to MME through HeNB GW, the most also needs further by source HeNB
Trigger the context of its HeNB GW connected release UE.But, due to HeNB GW existence
Incomprehensiveness, when HeNB is not connected to HeNB GW, source HeNB still can send message and touch
Sending out HeNB GW and discharge UE context, in such a scenario, MME i.e. can receive redundancy signaling,
Therefore need system to add extra treatment mechanism to process these redundancies.

Add clearly, below the present invention is described in detail by use embodiment.
Embodiment 1
It is successfully established S1 according to existing system flow process, HeNB with MME or HeNB GW to be connected
After, then can accept connection or the switching access request of UE.When a certain UE is based on S1 handover operation
When flow process is switched to target HeNB, core network element MME can send for execution to target HeNB
Handover request (HANDOVER REQUEST) message of handover operation UE.When target HeNB connects
When receiving HeNB GW, from MME send HANDOVER REQUEST message need through
HeNB GW just can arrive target HeNB.When HANDOVER REQUEST message is passed through
When HeNB GW is forwarded to target HeNB, HeNB GW needs to carry extra two within the message
IE:GUMMEI and MME UE S1AP ID 2, wherein GUMMEI serves this UE
The mark of MME, MME UE S1AP ID 2 be by the MME serving this UE be this UE distribution
Service identifiers.When HeNB is not connected to HeNB GW, when being directly connected to MME, then exist
HANDOVER REQUEST message need not carry above-mentioned two IE.
As in figure 2 it is shown, when HeNB2 is as target HeNB of S1 handover operation, arrive receiving
Decision can be performed, when this message when HANDOVER REQUEST message on S1 interface
In when carrying GUMMEI and MME UE S1AP ID 2 the two IE, HeNB2 can be determined that
Go out to connect himself to HeNB GW, otherwise, then can be determined that out and oneself be not connected to HeNB GW,
And it is directly to MME.After HeNB2 completes decision, then according to the knot of this decision
Fruit arranges the value of the state variable created before it, for convenience, names this state to become
Amount is HeGW_Conn_State, after the value of HeGW_Conn_State is provided with,
The value of HeGW_Conn_State can reflect whether this HeNB is connected to HeNB GW.
As in figure 2 it is shown, a certain UE based on X2 handover operation flow performing from source base station to HeNB2
During handover operation, HeNB2 can complete the stage to MME transmission PATH SWITCH in switching
REQUEST message.This message can trigger MME and perform correspondingly to operate, to complete core net to UE
Route conversion so that complete UE handover operation from source base station to HeNB2.At HeNB2 based on S1
Before interface sends PATH SWITCH REQUEST message, need first to determine how to encapsulate this and disappear
Breath, concrete decision is as follows:
HeNB2 first looks at the value of the HeGW_Conn_State state variable oneself preserved, if
The value of HeGW_Conn_State reflects and oneself is attached to HeNB GW, then will send
PATH SWITCH REQUEST message needs carry cell Source MME GUMMEI, should
Cell is used to indicate the UE being carrying out handover operation being connected to clothes during core net based on source base station
The mark of business MME.If the value of HeGW_Conn_State reflects that oneself is not connected to
HeNB GW, then need not carry letter in the PATH SWITCH REQUEST message that will send
Unit Source MME GUMMEI.
When HeNB2 completes the judgement for PATH SWITCH REQUEST signaling message encapsulated content
After operation, can encapsulate and send this message based on S1 interface.
Embodiment 2
With embodiment 1, in the present embodiment, HeNB1 is still based on the HANDOVER received
REQUEST message performs decision, and arranges state variable HeGW_Conn_State further
Value to reflect whether it is connected to HeNB GW.As it is shown on figure 3, a certain UE switches based on X2
During operating process performs the handover operation from HeNB1 to target BS, complete the stage in switching,
Target BS can send customer equipment context release (UE CONTEXT RELEASE) to HeNB1
Message, to trigger the context that HeNB1 release is carrying out the UE of handover operation.HeNB1 receives
After UE CONTEXT RELEASE, need to perform decision further as follows:
HeNB1 first looks at the value of the HeGW_Conn_State state variable oneself preserved, if
The value of HeGW_Conn_State reflects and oneself is attached to HeNB GW, then can determine that and need base
Instruction message is sent to its HeNB GW connected, to trigger HeNB GW release in S1 interface
Perform the context of the UE of handover operation.If the value of HeGW_Conn_State reflects that oneself does not has
It is connected to HeNB GW, then can determine that being not needed upon the triggering of S1 interface sets up what S1 was connected with it
Opposite end network element release is carrying out the context of the UE of handover operation.
After HeNB1 completes above-mentioned decision, can perform to operate further based on result of determination.
Embodiment 3
With embodiment 1, in the present embodiment, HeNB1 and HeNB2 is still based on receiving
HANDOVER REQUEST message performs decision, and arranges state variable further
The value of HeGW_Conn_State is to reflect whether it is connected to HeNB GW.As HeNB1 and
After HeNB2 has known whether it be connected to the result of HeNB GW, mutually inform based on X2 interface
The most whether opposite end HeNB storage and/or renewal are connected to the result of determination of HeNB GW.
As shown in Figure 4, when a certain UE based on X2 handover operation flow performing from HeNB1 to HeNB2
Handover operation during, in handoff preparation phase, HeNB1 is sending HANDOVER to HeNB2
Need to perform decision before REQUEST message, as follows:
HeNB1 first looks at whether reflection oneself is directly connected to the state variable of HeNB GW
Whether value and the reflection HeNB2 of HeGW_Conn_State_1 are directly connected to HeNB GW's
The value of state variable HeGW_Conn_State_2.If the value of two state variables reflects
HeNB1 and HeNB2 is not connected to HeNB GW, and HeNB1 and HeNB2 is
Be uniquely coupled to a MME time, then in the HANDOVER REQUEST message that will send
In need not carry cell GUMMEI, this cell is used to indicate the UE being carrying out handover operation to exist
The mark of service MME during core net it is connected to based on HeNB1.If be unsatisfactory for HeNB1 and
HeNB2 is not connected to the condition of HeNB GW or is unsatisfactory for HeNB1 and HeNB2 and is
During uniquely coupled condition to a MME, then at the HANDOVER REQUEST that will send
Message needs carry cell GUMMEI.
When HeNB1 completes to grasp for the judgement of HANDOVER REQUEST signaling message encapsulated content
After work, can encapsulate and send this message based on X2 interface.
Embodiment 4
With embodiment 1, embodiment 2 and embodiment 3, in the present embodiment, HeNB is still based on connecing
The HANDOVER REQUEST message received is to perform decision, and the state that arranges further becomes
The value of amount HeGW_Conn_State is to reflect whether it is connected to HeNB GW.Wherein, domestic base
Stand and can all carry out decision when receiving HANDOVER REQUEST message every time, or,
Set decision condition, when base station from home receives HANDOVER REQUEST message and meets it and sets
Decision is just performed during fixed decision condition.
When a lot of UE are switched to HeNB based on S1 handover operation flow process at short notice, HeNB can
Can receive HANDOVER REQUEST message for several times at short notice, and
