The embodiments of the present invention provide a method for heartbeat packet processing by using a proxy, an apparatus, and a communications system. The method includes: receiving, by a host, a first heartbeat packet sent by a first application in a client, where the client is a terminal that accesses the host by using a short range communications technology; and determining, by the host according to the first heartbeat packet and a first preset list, whether the first application is included in the first preset list. Thus, an objective of saving power for the host and the client can be achieved.

A display control method and a terminal device are provided. The display control method is applied to a terminal device having a transmissive liquid crystal display (LCD), and a backlight side of the transmissive LCD has a mechanical structure. The method includes detecting an operating status of the terminal device, turning off the transmissive LCD of the terminal device when the terminal device is in a standby state, and controlling the transmissive LCD to be in a transparent state to display the mechanical structure on the backlight side of the transmissive LCD. Hence, the method reduces power consumption of the terminal device and retains a watch function of displaying time by the terminal device.

The present invention discloses a method and an apparatus for compressing and decompressing an IP data packet. The method includes: performing, by a first device, compression processing on IP data in an IP data packet according to a first compression algorithm; and encapsulating, by the first device, the IP data after the compression processing into a packet data convergence protocol (PDCP) data packet, where header information of the PDCP data packet includes identifier information, where the identifier information is used to indicate the first compression algorithm or indicate that the IP data is compressed.

A bandwidth configuration method includes: A terminal acquires that a narrow bandwidth mode is used at a network side by a downlink transmission signal and/or an uplink transmission signal; and the terminal configures a receiving bandwidth and/or a transmitting bandwidth, where the receiving bandwidth and/or the transmitting bandwidth corresponds to the narrow bandwidth mode at the network side. The terminal side can acquire whether the network side uses the narrow bandwidth technology, and automatically adjust a bandwidth of a corresponding channel at the terminal side when the network side uses the narrow bandwidth technology, so that intra-system performance loss and inter-system interference that are caused by different bandwidth modes between the terminal side and the network side are avoided, thus improving performance of a communication system.
