Abstract
The invention discloses a congestion control method and congestion control equipment. The method comprises the following steps that: network side equipment receives a session management request message from user equipment (UE); and if a current network is in an overloaded state, when the session management request message is used for requesting the establishment of packet data network (PDN) connection of an emergency service, or the session management request message is not used for requesting the establishment of the PDN connection of the emergency service and the PDN connection of the emergency service currently exists, the network side equipment deletes the PDN connection of a non-emergency service in the context of the UE by issuing a PDN disconnection process, so that the UE enters an emergency attach state. According to the embodiment of the invention, the congestion degree of nodes of a core network is reduced, and a network load is alleviated.
Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of method and apparatus of congestion control.
Background technology
In existing protocol, propose based on APN(Access Point Name, APN) congestion control (APN based Congestion control) mechanism, and it can be divided into the mobile management based on APN to control (APN based Mobility Management control) and the conversation management control (APN based Session Management control) based on APN.
In the mobile management based on APN controls, network side needs the UE(User Equipment contracting special APN, subscriber equipment) carry out congestion control, and when the UE contracting special APN sends mobile management request to network side, network side judges whether this special APN occurs congested, if so, then network side refuses this mobile management request, and in the refuse information returned to UE, carry mobile management back off timer (back-off timer); And UE is after receiving mobile management back off timer, need no longer to initiate any mobile management process before this mobile management back off timer time-out.
Based in the conversation management control of APN, congestion state is in when network side determines certain APN, then network side needs refusal for the PDN(Packet Data Network of this APN, packet data network) connection request (Connectivity Request), and session management back off timer is carried in the refuse information returned to UE; And UE is after receiving session management back off timer, need no longer to initiate any session management procedure for this APN before this mobile management back off timer time-out.
In addition, except the congestion control based on APN, currently also proposed NAS(Non Access Stratum, Non-Access Stratum) the mobile management congestion control mechanism of layer; Concrete, under the condition of network over loading, network side can refuse any mobile management request of UE, and carries mobile management back off timer in the refuse information returned to UE; And UE is after receiving mobile management back off timer, need no longer to initiate any mobile management process before this mobile management back off timer time-out.
Realizing in process of the present invention, inventor finds at least there is following problem in prior art:
Due to the hierarchical design of NAS, mobility management layer and session management layer are independently maintained, UE, receiving after for the refuse information of mobile management request and mobile management back off timer, can not initiate mobile management request again; But for session management procedure, its congestion control is based on APN, and after UE enters connected state, during network over loading, permission is also sent session management messages by UE, thus increases offered load.
Summary of the invention
The embodiment of the present invention provides a kind of method and apparatus of congestion control, to alleviate offered load.
In order to achieve the above object, the embodiment of the present invention provides a kind of method of congestion control, comprising:
Network equipment receives the session management request message from user equipment (UE); If current network is in overload, then:
When described session management request message is to ask the packet data network PDN setting up urgent emergency business to connect, or described session management request message be not that PDN in order to ask to set up emergency business connects and the PDN of current built vertical emergency business connects time
Described network equipment goes to connect the PDN connection that disconnection process deletes the non-emergency business in described UE context by by initiating PDN, makes described UE enter emergency attached emergency attach state.
The embodiment of the present invention provides a kind of network equipment, comprising:
Receiver module, for receiving the session management request message from user equipment (UE);
Processing module, if be in overload for current network, then: when described session management request message is to ask the packet data network PDN setting up urgent emergency business to connect, or described session management request message be not that PDN in order to ask to set up emergency business connects and the PDN of current built vertical emergency business connects time
Going to connect the PDN connection that disconnection process deletes the non-emergency business in described UE context by by initiating PDN, making described UE enter emergency attached emergency attach state.
Compared with prior art, the embodiment of the present invention at least has the following advantages: in the embodiment of the present invention, go to connect by initiating PDN disconnection() the non-emergency(that deletes in UE context of process is urgent) PDN of business connects, thus reduce the Congestion Level SPCC of core net node, alleviate offered load.
