Embodiment 1

[0096] This embodiment introduces one of the implementation methods for switching services from the CN path to the D2D path. The application scenario of this embodiment is that UE1 and UE2 have established a core network data connection. When they are close to each other, the data detoured from CN Can be passed from the local connection path. Figure 4 is a flow chart of the first implementation of switching from a CN path to a D2D path according to an embodiment of the present invention, as shown in Figure 4 As shown, the process includes the following steps (step S402-step S426):

[0097] In step S402, the two UEs complete the discovery process with each other, and this process may depend on the existing D2D discovery process. Or the two users find that they are very close to each other and issue instructions to the terminal, so that it may not be necessary to execute the D2D discovery process between the two terminals or the terminal and the network in this step.

Embodiment 2

[0112] This embodiment introduces the second implementation method of switching services from the CN path to the D2D path. Figure 5 It is a flow chart of the second implementation of switching from a CN path to a D2D path according to an embodiment of the present invention. The application scenario of this embodiment is similar to that of Embodiment 1, and the implementation is also similar. The difference lies in the stage of UE requesting resources. There are some differences, that is, step S504-step S512 is different from step S406-step S412 in the first embodiment, and other steps are similar, such as Figure 5 As shown, the process includes the following steps (step S502-step S526):

[0113] In step S502, the two UEs complete the discovery process with each other, and this process may depend on the existing D2D discovery process. Or the two users find that they are very close to each other and issue instructions to the terminal, so that it may not be necessary to execut...

Embodiment 3

[0121] This embodiment introduces the third implementation method of switching services from the CN path to the D2D path. Figure 6 is a flow chart of the third implementation mode of switching from a CN path to a D2D path according to an embodiment of the present invention. The application scenario of this embodiment is similar to that of Embodiment 1, for example Figure 6 As shown, the process includes the following steps (step S602-step S628):

[0122] In step S602, the two UEs complete the discovery process with each other, and this process may depend on the existing D2D discovery process. During this process, UE1 and UE2 need to go to the eNB for identity verification respectively, so as to ensure that the two UEs can communicate with each other.

[0123] In step S604, the eNB receives a verification request from UE1 and / or UE2, and the request needs to carry identifications of each other. The eNB associates the contexts of the two users according to the locally stored...

Abstract

The invention discloses a communication path switching method, system and device. Wherein, the method includes: the MME receives a request message; where the request message is used to request communication on the D2D path; the MME sends a bearer resource processing request message to the GW; where the bearer resource processing request message is used to notify the network side The data path is switched from the CN path of the core network to the above-mentioned D2D path for transmission. Receiving the above request message by the MME includes: the above MME receiving the above request message sent by the base station; or, the MME receiving a bearer processing request sent by at least one of the two user equipments that have performed D2D communication through the above base station. The present invention solves the problem in the related art that path switching cannot guarantee the continuity of data services, thereby ensuring the continuity of data services during path switching, improving the quality of path switching, and enhancing user experience.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a communication path switching method, system and device. Background technique [0002] In order to maintain the competitiveness of the third-generation mobile communication system in the communication field, provide users with faster rate, lower delay, and more personalized mobile communication services, and reduce the operating costs of operators, the Third Generation Partnership Project ( The 3rdGeneration Partnership Project, referred to as 3GPP) standard working group is working on the research of the evolved packet system (Evolved Packet System, referred to as EPS). figure 1 is a schematic structural diagram of an evolved packet domain system according to related technologies, such as figure 1 As shown, the entire EPS system is divided into two parts, the wireless access network and the core network. The radio access network is composed of an evolved base station (E-UTR...
