Problems solved by technology

However, if the UE does not move between systems or deletes the established PDU session (PDU session) or the QoS flow in it, the pre-made QoS flow and EPS bearer QoS mapping will be wasted, resulting in a waste of signaling resources

Embodiment Construction

[0096] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0097] Such as figure 1 As shown, the information processing method of the embodiment of the present invention is applied to AMF, and the method includes:

[0098] Step 101. When the UE in the idle state moves from the 5G network to the LTE network, a context request from the MME is received during the process of the UE initiating a TAU update.

[0099] Wherein, the context request of the MME is sent by the MME when receiving a TAU (Tracking Area Update, tracking area update) request from the UE, wherein the TAU request message does not carry EPS bearer information.

[0100] In the context request, a mapped (mapped) GUTI (Globally Unique Temporary UE Identity, Globally Unique Temporary ...

Abstract

The invention provides an information processing method and apparatus, a device and a computer readable storage medium, and relates to the technical field of communication for saving signaling resources. The information processing method provided by the invention comprises the following steps: when user equipment UE in an idle state moves from a 5G network to an LTE (long term evolution) network,receiving a context request of an MME (Mobility Management Entity) in a process when the UE initiates TAU (tracking area update); storing a corresponding relationship between a session management function entity and a DNN (data network name) of a PDU (Protocol Data Unit) session of the UE in subscription data of the UE; or, requesting the session management function entity to perform EPS QoS (Quality of Service) mapping according to the context of the PDU session, and returning an EPS (Evolved Packet System) QoS parameter generated by the EPS QoS mapping; and sending the context of the UE to the MME. By adoption of the information processing method provided by the invention, the signaling resources can be saved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to an information processing method, device, equipment, and computer-readable storage medium. Background technique [0002] With the development of communication technologies, 5G networks need to support interoperability with LTE (Long Term Evolution, Long Term Evolution) networks. In the current interoperability scheme for UE (User Equipment, user equipment) in an idle state to move across systems, it is first required that when the UE establishes a PDU (Protocol Data Unit, protocol data unit) session, the network completes the QoS (Quality of Service) of the PDU session. , Quality of Service) flow (flow) and EPS (Evolved Packet System, evolved packet system) QoS mapping, and then complete the inter-system movement through the normal registration update or TAU (Tracking Area Update, tracking area update) process. However, if the UE does not move between system...
