Path switching method and apparatus based on user text information

A path switching method based on user text information, comprising:

• receiving, by a target radio access network (RAN) node, a resume request message sent by a user equipment (UE), and sending a user text obtain request message to a source RAN node;
• receiving, by the target RAN node, a user text obtain response message sent by the source RAN node, wherein the user text obtain response message carries user text information on the source RAN node;
• and
• after a data transmission channel is established between the source RAN node and the target RAN node according to information carried in the user text obtain request message, receiving, by the target RAN node, data cached locally and forwarded by the source RAN node.

A path switching apparatus based on user text information, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor,
• wherein the processor is configured to:
• receive a resume request message sent by a user equipment (UE);
• send a user text obtain request message to a source base station directly or through a mobility management entity (MME), wherein the user text obtain request message carries at least one of:
• a user text resume identifier (ID), a user text ID, or an MIME ID;
• receive a user text obtain response message sent by the source base station, wherein the user text obtain response message carries user text information found by the source base station according to information carried in the user text obtain request message;
• send a path switch request message for requesting user text resume to the MME;
• and
• receive a path request response message sent by the MME to complete the user text resume after the user text information is activated by the MME according to the path switch request message for requesting user text resume.
