The foundation and release carried in access network processed.
With demand growth, EPS (Evolved Packet System, evolved packet system) gateway progressively generates one
A little constraints.User data stream process concentrates on PDN egress gateways, causes gateway device function numerous and diverse, poor expandability.Gateway
Chain of command highly couples with forwarding surface, is unfavorable for core net smooth evolution.Forwarding surface dilatation demand frequency is higher than chain of command, tight coupling
Conjunction causes chain of command forwarding surface synchronization dilatation, and renewal of the equipment cycle short-range missile causes composite cost increase.Network layer data forwarding is difficult to
User, service feature are identified, is only capable of being forwarded according to the QoS of upper layer transfers, causes network resource usage poorly efficient, it is difficult to according to user
Data stream is finely controlled with traffic performance.In addition, a large amount of strategies need manual configuration, management complexity is caused to increase,

Network Development and the demand of market application.
Fig. 2 is the configuration diagram that GW chains of command and user plane separate under non-roaming scene in correlation technique.The framework will
S/PGW in original EPS frameworks has split into GwC (Gateway Controller) and GwU (Gateway User) two classes
Functional network element.
Wherein, GwC includes SGwC and PGwC, corresponds to SGW and PGW chain of command respectively, is responsible for the choosing of load sharing, GwU

The user plane and chain of command interface of docking are corresponded on S/PGwC and S/PGwU respectively, remaining the corresponding interface function pair
According to former EPS frameworks.
After GW chains of command and user plane separation, solve above-mentioned problems existing for EPS gateways, but be also introduced into simultaneously
New technical problem.For example, after existing customer location is moved, bearing resource is caused to waste and throw in some scenarios
Pass the elongation of user's message time delay.
In present mechanism, MME carries out SGW selection according to customer location and signing information etc..When customer location occurs
It is mobile that MME judges whether to need the gravity treatment for carrying out SGW when triggering switching and tracing section updating flow, and carry out SGW selections and on
The information updating of downlink data transmitting path.PGW does not change as anchor point.If judge to need the gravity treatment for carrying out SGW, basis
Positional information and signing information after renewal reselect suitable SGW, and by the SGW uplink users face address newly selected and tunnel
The information such as road mark are sent to eNodeB, update upstream data transmitting path information, it is ensured that the correct transmission of upstream data.And will
New eNodeB information, such as eNodeB downlink users face address and Tunnel Identifier are sent to SGW, update downlink data transmission path
Footpath information, ensure the correct transmission of downlink data.If SGW gravity treatment need not be carried out, by current SGW uplink user face
The information such as address and Tunnel Identifier is sent to new eNodeB, and new eNodeB downlink users face address and Tunnel Identifier are passed
Current SGW is given, carries out the reconstruction of up-downgoing data channel.In switching flow, whether MME changes is held with the application discussion
Carry the wasting of resources and delivery user's message time delay elongation problem is unrelated, can refer to current mechanism processing, do not do expansion description herein.
After SGW chains of command and user plane functions separate, the GW selections that MME is carried out according to current mechanism are really GWC's
Selection, it is responsible for carrying out GWU selection and management in its corresponding GWU group by GWC.Then according to mechanism as described above, Yong Huwei
Put after being moved, PGW does not change as anchor point, i.e. PGwC and PGwU do not change, and need not switch but SGwU meetings in SGwC
It may then cause to waste bearing resource and elongate under the scene of gravity treatment to deliver user's message time delay.
For example, after user initiates the EPS networks that attachment is linked into chain of command and user plane separates, GWC can be according to nearby
Principle selects SGwU and PGwU to save bearing resource and to improve Consumer's Experience, and upstream data is sent out after reaching eNodeB to SGwU
Send, SGwU is sent to PGwU, and downlink data is then that opposite direction is sent to eNodeB.After customer location is moved, occur
S1 switches.After MME receives former eNodeB handover request message, MME judges that SGwC need not be changed, and GWC can be according to nearby
Principle selects SGwU, and such SGwU needs to change, and upstream data can be sent after reaching eNodeB to new SGwU, new SGwU to
The PGwU that accesses before is sent, but new SGwU and the PGwU physical locations distance that accesses before may farther out, between it
Route is elongated, and is caused bearing resource to waste and deliver user's message time delay and is elongated.
Therefore, after GW chains of command and user plane separate, SGwU changes after customer location is moved, and causes
Bearing resource can not be saved under some scenes, so as to which the experience formedness of business can not be ensured.
