Along with the rapid growth of smart phone and application thereof, the capacity of carrier network is challenged, particularly in the time having special event to occur, user may use smart phone to carry out multiple application, and the news that for example surfs the web is upgraded blog, release news, voice and video phone etc., the burst of a large amount of such application, by consuming fast the capacity of carrier network, causes network congestion.But, in some country, government wishes, in disaster etc., area occurs, carrier network can for example, provide access for some special applications (can short message issue and take the few special applications of Internet resources), and the disaster area people can both be kept and the contacting of household by special applications.Therefore Carrier Requirements, in the time of network startup congestion control, still can provide access for some special applications.
In 3GPP meeting, successfully relevant data communication congestion control mechanism is applied in project verification research, mainly comprises following research contents:
Analyze use-case and the potential demand of the special applications initiating communication of allow/restriction operator definition;
Analyzing existing access control mechanism can not make network indicating user terminal (User Equipment, UE) go the defect of allow/restriction special applications access;
Consider the backwards compatibility of existing access control mechanism.
At present, the congestion control mechanism of core-network side is mainly the congestion control mechanism of Non-Access Stratum (Non Access Stratum, NAS) level.
Existing 3GPP agreement has proposed based on Access Point Name (Access Point Name, APN) congestion control (APN based Congestion control) mechanism, be divided into the APN control (APN based Session Management control) of controlling (APN based Mobility Management control) and dialogue-based management based on the APN of mobile management, network judge certain APN congested according to being:
The maximum number of evolved packet system (Evolved Packet System, the EPS) carrying (bearer) of the activation of each APN;
The maximum rate that the EPS bearer of each APN activates;
One or more packet data gateway (PDN GW) that APN is corresponding are unreachable or to Mobility Management Entity (Mobile Management Entity, MME)/Serving GPRS Support Node (Serving GPRS Support Node, SGSN) has been indicated congested;
The contracted maximum rate of mobile management (Mobility Management, MM) signaling request of equipment of special APN;
Setting in network management.
APN based Mobility Management control is achieved as follows:
Network carries out APN based mobility management congestion to the UE of the special APN that contracted, when this type of UE initiates mobile management request (Mobility Management request, MM request) when the network, network judges whether this special APN occurs congested, if, refuse this MM request, and may carry mobile management and keep out of the way timer (Mobility Management back-off timer, MM back-off timer) information is to UE, UE is receiving after MM back-off timer information, before this MM back-off timer is overtime, no longer initiate any Mobility Management process.
APN based Session Management control is achieved as follows:
In the time that network is judged certain APN in congestion state, refusal is for packet data network (the Packet Data Network of this APN, PDN) connection request (PDN Connectivity Request), and in refuse information, carry session management and keep out of the way timer (Session Management back-offtimer) information, UE, after receiving this timer information, no longer initiates any Session Management process for this APN.If do not provide APN in PDN connectivity Request message, network judges acquiescence APN(default APN) whether congested, and determine whether to accept this PDN connection request according to judged result.
Except the congestion control based on APN, existing 3GPP agreement has also proposed the Mobility Management congestion control mechanism of general NAS layer, propose under general network over loading condition, network can be refused any Mobility Management signaling request of UE, and in refuse information, carries Mobility Management back-off timer information.
From prior art, in the time of network congestion, network side can start to service request the congestion control mechanism of NAS layer, thereby service request is rejected, and in the time of network congestion, how can, for some special applications provides access, also there is no concrete implementation at present.
