Problems solved by technology

However, for a UE already in the connected state, even if the mobility management backoff timer is running, session management signaling can still be initiated, including PDN connection requests initiated for non-emergency services, and these signaling will undoubtedly increase network congestion.

specific Embodiment 1

[0051] Specific embodiment 1. In this embodiment, the UE is a Rel-10 version, is configured as a low-priority non-access stratum signal, and is in a connected state. For a UE configured as a low-priority non-access stratum signal, the application layer entity The session management requests of different applications have the same priority (that is, low priority). This embodiment is based on the Evolved Packet System (EPS), as attached figure 2 As shown, the detailed process of network congestion control is as follows:

[0052] Step 201: the application app1 of the UE application layer entity requests the ESM (EPS SM) entity to establish a packet data network (PDN) connection to APN1 for it.

[0053] Step 202: After the ESM entity determines that no session management backoff timer of APN1 is running, the ESM entity sends a query request to the EMM (EPS MM) entity to query whether the EMM entity has a mobility management backoff timer running.

[0054] Step 203: The EMM entit...

specific Embodiment 2

[0058] Specific embodiment 2. In this embodiment, the UE is in the connected state and has multiple priorities. For example, the UE is configured as the normal priority of the non-access stratum, that is, the UE can initiate a session management request with normal priority and a session with low priority. Management request, this embodiment is based on the EPS system, as attached image 3 As shown, the detailed process of network congestion control is as follows:

[0059] Step 301: the application app2 with the priority of normal priority in the application layer entity requests the ESM entity to modify the established bearer to APN2 for it.

[0060] Step 302: The ESM entity determines that there is no APN2 session management backoff timer running locally, and the ESM entity sends a query request to the EMM entity to query whether the EMM entity has a mobility management backoff timer running.

[0061] Step 303: The EMM entity inquires according to the query request that the...

Abstract

The invention discloses a network congestion control method and terminal which are used for controlling a session management request initiated by user equipment in a connected state under the circumstance of network congestion so as to effectively avoid intensifying of the network congestion. The network congestion control method comprises the following steps: when the UE is in the connected state, a session management (SM) entity of the UE inquires the operation information of a mobile management retreat timer in a mobile management (MM) entity of the UE before initiating the session management request; after ascertaining that the session management request is retreated by the mobile management retreat timer operating in the MM entity according to the operation information, the SM entity does not initiate the session management request.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a network congestion control method and a terminal. Background technique [0002] The third generation mobile communication standardization organization (3rd Generation Partnership Project, 3GPP) proposed an access point name (Access Point Name, APN)-based congestion control mechanism (APN basedMobility Management control). APN based Mobility Management control (APN based Mobility Management control) and APN based session management control (APN based Session Management control), in the TS23.401 standard stipulate the basis for the network side to judge whether APN is congested based on the APN congestion mechanism. [0003] In APN-based mobility management control, when a user terminal (UE) subscribed to a special APN initiates an attach request (attach request) to the network side, if the network judges that the special APN is congested, it rejects the UE’s attach ...
