Provided in the present invention are a data transmission method and device. In an embodiment of the present invention, in a condition in which a first node acquires whether an X2 interface is present between the first node and a second node, the first node directly transmits a forwarding address thereof to the second node, to address a problem in the related art regarding how to optimize data forwarding in a scenario of double connection switching, thereby improving flexibility and applicability of the data forwarding.

Data transmission method and device

The present document provides a method and apparatus for processing a warning message, an MME, a CBC and a base station. Herein, the method includes that: a first request message for requesting for broadcasting a warning message is transmitted to a base station, herein a warning area range in the first request message includes Public Land Mobile Network (PLMN) information (S); and a first response message sent by the base station is received, herein the first response message carries the PLMN information corresponding to issuing of the warning message (S).

Warning message processing method and device, MME, CBC and base station

Provided are methods and devices for reporting a broadcast state of a warning message. In the method, an evolved Node B (eNB) receives a state request message from a Mobile Management Entity (MME), wherein the state request message is used for requesting to report a broadcast state of a warning message; in response to the state request message, the eNB reports the broadcast state of the warning message to the MME. By means of the technical solution, the effect that a network side can report a broadcast state of a warning message according to a state request from a Cell Broadcast Center (CBC) is achieved.

Methods and devices for reporting broadcast state of warning message

Disclosed are a method and system for implementing an X2 proxy. The method includes that a function of a next-hop node serving as an X2 proxy of a previous-hop node () is activated; and X2 message interaction between an initial node and a target node is implemented through more than one X2 proxy including the previous-hop node and the next-hop node ().

Method and system for implementing X2 proxy

A method and system for notifying a transport layer address are disclosed. The method includes: a first base station sending transport layer address information of an X2 gateway connected to the first base station to a second base station, wherein, the first base station is a home base station (step); and the second base station initiating an X2 connection establishment flow according to the received transport layer address information of the X2 gateway (step). The system includes: a first base station, configured to: send transport layer address information of an X2 gateway connected to the first base station to a second base station; wherein, the first base station is a home base station; and the second base station, configured to: initiate an X2 connection establishment flow according to the received transport layer address information of the X2 gateway.
