Abstract: A binder is a polymer including structural units represented by a formula I, a formula II, and a formula III. R1 is selected from any one of a substituted or unsubstituted C1-C10 alkyl group, a substituted or unsubstituted C2-C10 alkenyl group, a substituted or unsubstituted C2-C10 alkynyl group, or a substituted or unsubstituted C6-C20 aryl group; R2 is selected from a phenolic hydroxyl group and the number of phenolic hydroxyl groups is 2 to 5; R3 is one of C, S, N, or P; X is selected from any one of Li, Na, or K; R4 and R5 each are independently selected from one of a hydrogen atom, a substituted or unsubstituted C1-C10 alkyl group, a substituted or unsubstituted C2-C10 alkenyl group, a substituted or unsubstituted C2-C10 alkynyl group, or a substituted or unsubstituted C6-C20 aryl group; and n1, n2, and n3 each are independently an integer greater than zero.

Abstract: An embodiment of the present application relates to the field of communication technologies, and particularly to a data offloading method and a gateway, for achieving data offloading and relieving pressure on a core network. The data offloading method according to the embodiment of the present application is applied to a long term evolution (LTE) system including a base station, a gateway, a core network, and a local server, wherein the base station establishes a link with the core network via the gateway and the base station establishes a link with the local server via the gateway. The method comprises: a gateway receives a first data packet transmitted by a base station, wherein the first data packet comprises first data; and the gateway transmits the first data to a local server upon determining that the first data packet is not a VoLTE data packet in an LTE system, thereby achieving offloading of non-VoLTE data and thus relieving the pressure on a core network.

Abstract: Disclosed in the present invention are a data transmission method and processing method, and a device, which are used for improving the compression effect on an original message during tunnel transmission, wherein the data transmission method comprises: obtaining an original message to be transmitted and a current reference message, the current reference message and the original message being transmitted in the same tunnel; differentiating and compressing the original message and the current reference message to obtain an information message; encapsulating the information message by using a tunneling protocol to generate a tunnel message, the tunnel message comprising a compression information header, and the compression information header comprising a reference message identifier corresponding to the current reference message; and sending the tunnel message. With the disclosed method, each message in the same tunnel have a certain correlation.
