摘要:
A handover method is provided, in which a measure of signal strength is obtained between a user terminal and each of one or more candidate cells, relative to signal strength between the user terminal and a source cell. For candidate cells, a threshold is set that depends on a measure of loading of the source cell and a measure of loading of the candidate cell. For the target cell, a particular candidate cell is identified for which the measure of signal strength exceeds the threshold set for that particular cell. The user terminal is connected to the target cell. In specific embodiments, the threshold for each candidate cell depends on a load differential between the source cell and the candidate cell.

摘要:
The present invention relates to a method for sending channel quality information in a multi-carrier radio communication system comprising at least one mobile terminal and at least one base station, said channel quality information being sent on a signaling channel by said mobile terminal to said base station. According to the present invention, the method comprises the steps of: performing channel quality measurements on a plurality of frequency sub-carriers; generating and sending a first report over said signaling channel, said first report comprising a first channel quality information depending on said channel quality measurements on at least one sub-carrier, said at least one sub-carrier building an herein called first group of sub-carriers; determining a number of additional reports depending on the mobility grade of said mobile terminal; if said number of additional reports is not reached, generating and sending an additional report over said signaling channel comprising an additional channel quality information depending on channel quality measurements on at least one sub-carrier, said at least one sub-carrier building an herein called second group of sub-carriers, said second group of sub-carriers being different of said first group of sub-carriers.
摘要:
The present invention relates to a method of operating a base station (10) of a wireless communications network, wherein data is transmitted between said base station (10) and a radio network controller (20). The inventive method is characterized in that said base station (10) automatically issues a first capacity allocation message (CAM—1) to the radio network controller (20) which comprises capacity information on a basic data transfer capacity currently supported by the base station (10). The present invention further relates to a base station (10) and a radio network controller (20) of a wireless communications network.
摘要:
A method for controlling the flow of data between an RNC and a base station of a UMTS mobile communications system with HSDPA capability via an Iub interface, where an HS-DSCH Frame Protocol mechanism is implemented in the Iub interface to provide control and data services for the communication of HSDPA user data between the RNC and the base station, wherein a capacity overload control entity monitors information about actual Iub interface data transport flow, and when a determined Iub interface transport capacity value is reached, the data transport flow is reduced in the Iub interface.
