A service processing method and mobile communication terminal

Abstract

The present invention provides a service processing method and a mobile communication terminal, wherein the service processing method includes: after receiving a rejection response message issued by the network side through 3GPP access, starting a backoff timer, and timing the backoff timer When the non-access stratum notification message sent by the network side through the non-3GPP access is received before the end, the backoff timer is stopped, and the service request process based on the 3GPP access is triggered. The solution of the present invention enables the mobile communication terminal to actively stop the backoff timer under 3GPP access when receiving the non-access stratum notification message through non-3GPP access, and trigger the service request process based on 3GPP access, so that the network side It is no longer necessary to perform paging through 3GPP access, saving air interface wireless resources.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a service processing method and a mobile communication terminal. Background technique [0002] In the prior art, for a mobile communication terminal UE registered to the same Access Mobility Management Entity or the same Public Land Mobile Network (PLMN) through the 3GPP access network and the non-3GPP access network, when the network is in In the congestion state, the network side may notify the UE to start the backoff timer through non-access stratum (Non-access stratum, NAS for short) signaling. When the network 3GPP access congestion is alleviated and the network side has 3GPP access downlink services for the UE, if the UE is in the connected state in the non-3GPP access state, and the 3GPP is in the idle state, the network side can send through the non-3GPP access The NAS notifies the UE of the message, but due to the existence of the backoff timer in the UE, the UE c...

Problems solved by technology

[0004] Embodiments of the present invention provide a service processing method and a mobile communication terminal to solve the problem of mobile communication terminals registered to the same access mobility management entity through a 3GPP access network and a non-3GPP access network in the prior art. When the non-access stratum notification message is sent through non-3GPP access, due to the existence of the backoff timer, the service request process based on 3GPP access cannot be triggered, and the service request process based on 3GPP access needs to be triggered again through the paging process , resulting in a waste of resources
