At present, small data transmission prioritization scheme is broadly divided into two classes:
The first kind is the prioritization scheme based on short message (SMS);
Equations of The Second Kind is by non-access (NAS) layer message is expanded, by small data message transmissions to Mobility Management Entity (MME), then by MME by small data message transmissions to MTC server (server).
In Equations of The Second Kind method, Mobility Management Entity (MME) can arrive MTC Server by small data message transmissions by two paths, article one, be that MME is through packet data network gateway (PDN GW, PGW) arrive again MTC Server, another be MME through IWF (Interworking Function, IWF) entity to MTC Server.
Wherein, MME mainly contains following two kinds of concrete schemes through MTC-IWF entity to the bang path of MTC Server:
First method, as shown in Figure 1, in the process of adhering at subscriber equipment (UE), MME is from home subscribed services device (Home Subscriber Server, HSS) subscription data of download user, comprises the address information of machine type communication IWF (MTC-IWF) entity in this subscription data.Suppose that MTC-IWF is not in the configuration of user's side, HSS need provide general MTC-IWF(Generic MTC-IWF) address of entity.When MME receives after the Non-Access Stratum that carries small data message (Non-Access Stratum, the NAS) message of UE transmission, obtain this small data message the address information based on obtaining from HSS and forward it to MTC-IWF entity.
The address that configures MTC-IWF entity in HSS can adopt following several approach: fully qualified domain name (FQDN) or Internet protocol (IP) address that MTC-IWF entity is provided for each UE in subscription data; Or, in subscription data, be FQDN or the IP address that each MTC APN (Access Point Name, APN) provides MTC-IWF entity; Or, FQDN or the IP address of general MTC-IWF entity are provided in HSS.
Second method, as shown in Figure 2, subscriber equipment (UE) carries MTC-AP PDU(Machine Type Communication Application-Packet Data Unit in up general NAS transmission (Uplink_Generic_NAS_Transport) message, Protocol Data Unit, machine type communication application-Packet Data Unit, or protocol Data Unit; Refer to the data cell of MTC communications applications layer) send to MME/SGSN, this MTC-AP PDU comprises MTC head and MTC data, in MTC head, UE comprises internal indicator and reception (receiver) territory, this internal indicator is for identifying UE sender's identity, for example can adopt international mobile subscriber identifier (International Mobile Subscriber Identifier, IMSI) as internal indicator, in receiver territory, preserve MTC server identification (MTC Server ID).
MME/SGSN, after receiving Uplink_Generic_NAS_Transport message, sends to this MTC-IWF entity by MTCx interface by MTC-AP PDU after determining suitable MTC-IWF entity, and MTCx is the interface between MME/SGSN and MTC-IWF entity.
Wherein, MME/SGSN determines suitable MTC-IWF entity according to the subscription data of this locality configuration or roaming agreement (roaming agreement) or UE.
MTC-IWF entity is resolved the MTC-AP PDU receiving, and according to obtain MTCServer ID from receiver territory, by MTCsp interface, MTC data is sent to corresponding MTC Server.And, at MTC-IWF, the internal indicator in MTC head being converted to the outside sign (External ID) of UE, operation layer can be according to this outside sign identification UE.Wherein, the outside sign of UE is by this locality sign (Local Identifier) and domain identifier (Domain Identifier, Domain ID), domain identifier has represented Mobile Network Operator (Mobile network operator, MNO) territory (domain) of controlling, can be for finding MTC-IWF entity.Local sign is distributed by MNO, in domain inside, is unique.
UE herein refers to intelligent terminal or the ordinary terminal equipment for MTC communication.
To sum up, in first method, do not discuss when MTC-IWF entity is connected with a plurality of MTC Server, MTC-IWF entity how to confirm receives the MTC Server of small data; In second method, needing UE to know MTC Server ID, according to the method, know that the application layer by UE provides MTC Server ID, is how to know MTC Server ID but the method does not illustrate application layer.Generally, when dispatching from the factory, UE can obtain MTC Server ID, but, when the MTC Server communicating by letter with UE changes, need to notify the MTC Server ID after UE changes, this will bring larger operation maintenance workload, and can reduce the flexibility that MTC business is carried out, meanwhile, also undeclaredly in the method how the internal indicator of UE is mapped as to outside sign.
