Description
Technical field
The present invention relates to field of communication technology, in particular to a kind of method and control plane node for selecting user face nodes.
Background technique
In the mobile communication network, PGW (Packet Data Network Gateway, packet data gateway) and SGW
(Serving Gateway, gateway) had not only had the function of control plane (i.e. processing control signaling), but also had user plane functions
(i.e. forwarding data packet).After the control plane and user plane functions of PGW and SGW are split as different network elements, operator can be
Multiple user face nodes are disposed in network, it is therefore desirable to carry out user face nodes selection；Further, due to EPC (4G core net
Network) system allow user apply for more users face resource (for example, bigger bandwidth etc.) when any, if with PDN (public affairs
With data network) connection granularity carries out user face nodes selection and appears in have enough can be used in other user face nodes of gateway
Resource but refuses the problem of user applies for new resources because currently carrying the user face nodes inadequate resource of customer flow.
It is as shown in Figure 1 mobile communications network framework, by taking non-roaming scene as an example.
(1) SGW is selected
SGW selects to refer to that MME (mobile management entity) selects one to provide the SGW of service for UE.The selection operation root
It is executed according to network topology, i.e. selected SGW can provide service in the location of UE, and preferred SGW is changed probability minimum by MME
SGW.Load balancing between SGW is also the criterion of SGW selection.When the SGW IP address that dns server returns includes weight
When parameter (weight factor), if necessary to consider load balancing, MME uses parameter selection SGW.It is specific for one
SGW, generally provide the power that the SWG is arranged in the relative capacity between the SGW of service according to the SGW and other same tracking area
Weight parameter.
If MME support GTP-C (tunneling protocol) load control, when MME select SGW when, MME not only consider from
The weight parameter that DNS (domain name system) server receives, it is also contemplated that the load information received from SGW.
(2) PGW is selected
Signing information that MME is provided using HSS (home signature user server) and other criterion (such as match in MME
SIPTO (IP data distribution)/LIPA (local IP access) of each APN (access point name) set supports information, between PGW
Load balancing etc.) it is that UE selects PGW.When the PGW IP address that dns server returns includes weight parameter, if requiring load
Equilibrium, MME select to use the parameter when PGW.PGW specific for one, generally according to the PGW and other and same APN phase
The weight parameter of the PGW is arranged in relative capacity between the PGW of pass.
When MME supports GTP-C (tunneling protocol) load control function, in addition to the weight that dns server returns is joined
Except number, MME selects to also consider the load information received from PGW when PGW.
HSS provide PDN (public data network) signing information include:
The mark of-APN and PGW, or
- APN, and whether allow to distribute PGW from VPLMN (virtual public land mobile communication network) or whether should be from
HPLMN (home public land mobile network network) distributes PGW；
Optionally, for an APN, if allow for the APN execute SIPTO above RAN (resident access net into
Row IP data distribution) and/or SIPTO at the Local Network (carrying out IP data distribution in local network)；
Optionally, it for an APN, executes LIPA and is conditional, it is forbidding or support.
PGW selection can support static PGW to select, and specific implementation is that the APN of configuration is mapped to one specifically
The PGW mark that PGW or HSS is provided is a static state PGW.
When UE has been coupled to one or more PDN, in order to establish to a PDN connection, UE is mentioned in request message
For APN, selected for PGW.If including a wildcard APN (wild card APN) in the PDN signing context that HSS is provided,
Any APN of UE request so can be used to establish PDN connection.If HSS provides the mark of the PGW of static allocation or HSS is provided
The mark and request type of the PGW of dynamic allocation is " switching ", then not needing to execute PGW selection.If HSS provides dynamic point
The mark of the PGW matched, HSS provide the identification information of the PLMN where the PGW simultaneously.
If HSS provides the mark of the PGW dynamically distributed, and request type is " initial request ", then HSS can be used to mention
The PGW of confession selects new PGW.If the APN of PDN connection supports SIPTO, the PGW that the position of distance UE should be selected close.
PGW mark refers to a specific PGW.If PGW mark includes IP address, which is the IP address of PGW, otherwise
PGW mark includes a FQDN, and MME parses the IP address of PGW using DNS function.
If the PDN signing context that HSS is provided allows to distribute PGW from VPLMN for the APN, and matches confidence in MME
Breath can be shown that there is roaming agreement between VPLMN and HPLMN, and MME derives a PGW mark from VPLMN.If can not derive
PGW is identified out, or signing does not allow to distribute PGW from VPLMN, then deriving that PGW is identified from HPLMN using APN.MME according to
APN, subscription data and other information derive that PGW is identified using DNS function.It is not IP if PGW mark is logical name
Location, then MME executes dns resolution using the protocol type (PMIP or GTP) of PGW mark and S5/S8 interface.It is configured in MME/SGSN
There is the S8 interface protocol of each HPLMN.
When UE provides APN, if the signing context that HSS is provided allows UE that the APN, MME is used to use the APN
Derive that PGW is identified.If having existed PDN connection relevant to APN, MME should select same PGW.
In the conventional method, MME is responsible for selecting SGW and PGW, after the control plane of SGW and PGW and the separation of user face,
MME can select the control plane node (being denoted as SGW-C, PGW-C) of SGW and PGW according to existing method, and the control plane node
Corresponding user face nodes may be multiple, it is therefore desirable to the selection of further progress user face nodes.Existing selection mechanism
The user face nodes for being unable to complete SGW, PGW in the case where control forwards separation architecture select work.Further, current mechanism only exists
The selection of SGW, PGW are carried out whens user initially adheres to and switches etc., there are multiple user face nodes (to be denoted as in SGW, PGW
SGW-U, PGW-U) when, do not account for the subsequent user face nodes inadequate resource for establishing new bearer (carrying) Shi Yixuan or
The case where load imbalance.
