Problems solved by technology

Therefore, for the D2D session, when the terminal moves on the EPS network, how to solve the seamless switching between the D2D bearer and the EPS bearer, so that the D2D session will not be disconnected or the session effect will be poor due to the movement of the terminal, and the user experience will be reduced. It is an urgent problem to be solved in the existing technology

Embodiment 1

[0088] This embodiment mainly describes that the D2D source end and the peer end connected to the same eNB are conducting a D2D session through the D2D bearer. At this time, the source end moves and leaves the D2D area. For the scenario where the terminal detects whether the range of the D2D area satisfies the D2D session, the D2D terminal may initiate a D2D session switching request to the network side when checking that the D2D area is critical. For the scenario where the eNB on the network side checks whether the D2D area meets the D2D session, the eNB can initiate a D2D session handover request to the MME when checking whether the D2D area is critical; At this time, it may decide whether to initiate a D2D session handover, and then notify the radio access network eNB to perform the session handover. The MME performs D2D communication inspection according to the D2D session handover instruction and decides to initiate a session handover from the D2D bearer to the EPS bearer...

[0115] This embodiment mainly describes that the D2D source end and the peer end connected to the same eNB are conducting a D2D session through the D2D bearer. At this time, the source end moves and leaves the D2D area. For the scenario where the terminal detects whether the range of the D2D area satisfies the D2D session, the D2D terminal may initiate a D2D session switching request to the network side when checking that the D2D area is critical.

Embodiment 3

[0146] This embodiment mainly describes that the D2D source end and the peer end connected to the same eNB are conducting a D2D session through the EPS bearer. At this time, the source end moves and enters the D2D area. For the scenario where the terminal detects whether the range of the D2D area satisfies the D2D session, the D2D terminal may initiate a D2D session switching request to the network side when checking that the D2D area is critical. For the scenario where the eNB on the network side checks whether the D2D area meets the D2D session, the eNB can initiate a D2D session handover request to the MME when checking whether the D2D area is critical; At this time, it may decide whether to initiate a D2D session handover, and then notify the radio access network eNB to perform the session handover. The MME checks the D2D communication according to the D2D session handover instruction and decides to initiate a session handover from the EPS bearer to the D2D bearer. The ne...

Abstract

The invention discloses a direct connection communication terminal session switching method and device in a mobile communication network. When a first D2D terminal and a second D2D terminal carry out session, and when the D2D area range changes, the network side launches the switching between D2D bearing and EPS bearing according to a D2D session switching request decision. According to the invention, seamless switching between D2D bearing and EPS bearing in the EPS network is realized; a user is prevented from the effect of interrupting or bad voice, which is caused by terminal moving; and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for switching a session of a directly connected communication terminal in a mobile communication network. Background technique [0002] In mobile communication, communication can occur between a user equipment (UE for short) (or also called a terminal, or a user terminal) and an application server (AS for short), or between two user equipments. between. The communication between two user equipments may be relayed through AS, or may be carried out through end-to-end IP data flow between two user equipments. [0003] In mobile communications, a Packet Service (PS for short) network and an Evolved Packet System (EPS for short) provide IP-based data communication. The IP address of the UE is in charge of the IP allocation entity in the network, and all IP data flows need to pass through the IP allocation entity. [0004] figure 1 It is a schematic...
