A method includes receiving a task processing request from user equipment (UE) and obtaining application layer information for the task processing request and capability information of the UE for the task processing request. The method also includes obtaining access stratum information. The method further includes sending, based on the capability information, the application layer information, and the access stratum information, processing indication information to an apparatus for executing the task. The processing indication information instructs the apparatus to process the task corresponding to the task processing request. The apparatus for executing the task is at least one of the UE, an access network device, a core network device, or an Internet server.

Embodiments provide a terminal control method, a radio network controller, and a base station. The method includes: determining, by an RNC, that a downlink serving base station of a terminal that establishes a connection with both a macro base station and a micro base station is the macro base station; acquiring, by the RNC, a target power control value, where the target power control value can be used to ensure that channel quality of an uplink control channel from the terminal to the macro base station reaches a target threshold; and sending, by the RNC, the target power control value to the micro base station.

Embodiments of the present invention provide a channel estimation method and a receiver. The method includes: determining a channel space related matrix of each channel according to first signals received by N antennas of a receiver on each channel of M channels, where the channel space related matrix of each channel is used to indicate space correlation between the N antennas on each channel, wherein N is a positive integer greater than 1, and M is a positive integer; determining a channel fading factor filter matrix according to the channel space related matrices of the M channels, where the channel fading factor filter matrix is an N&#xd7;N-dimensional matrix; and determining channel estimation of a first channel according to the channel fading factor filter matrix and channel fading factors corresponding to the N antennas when the N antennas receive first signals on the first channel.

A method and a device for signal processing in a communication system are provided. The method includes: performing sampling and time-frequency transform on a received first time domain signal to obtain a first frequency domain signal; performing modulus operation on the first frequency domain signal with respect to a preset threshold to obtain a second frequency domain signal; performing inverse time-frequency transform on the second frequency domain signal to obtain a second time domain signal, and performing despreading on the second time domain signal. The embodiments of the present invention can avoid the problem in the prior art that not only the NBI signal but also the SS signal which is a useful signal are filtered out, which results from frequency domain signals of a certain number of frequency points being set to zero, and thereby improve the reliability of signal reception.

The present invention provides an improved solution of registering with a Home Agent HA of a Mobile Node MN, comprising: grouping at lest two Foreign Agents FAs to form a Foreign Agent Group FAG to enable FA members of the FAG to share information of the MN roaming into a FAG coverage area; when any FA member of the FAG receives a registration request for registering a care-of address with the HA sent by the MN, determining whether the MN enters the FAG coverage area for the first time based on the shared MN information; and if the MN enters the FAG coverage area for the first time, the FA forwards the received registration request to the HA; otherwise, the FA directly sends a registration response to the MN. The solution of the present invention greatly reduces registration messages from the MN to the HA, thereby reducing signaling delay produced when the MN moves in the FN. Also, both the MN and the HA in the prior art can be merged into the solution, thereby achieving seamless integration with IPv4, preferably with Mobile IPv4 scheme.
