Abstract:
A method and apparatus is described herein for controlling the operating temperature of radio equipment (44, 46) in a radio base station (10) while preventing a decrease in power of a common channel. A radio base station (10) according to the present invention includes a radio unit (40) and a control unit (20). The radio unit (40) determines a temperature of the radio unit (40), e.g., by determining a temperature of high power radio equipment (46) in the radio unit (40). The control unit (20) allocates a desired power to the common channel, determines an available power for dedicated and/or shared channels based on the allocated power for the common channel and a power limit derived from the determined temperature, and allocates the available power to the dedicated and/or shared channels.
Abstract:
A control signal data processing load associated with mobile terminals currently having a connection with a radio access network is regulated. The connection is terminated when the control processing cost for maintaining the connection exceeds the benefit of maintaining the connection to achieve shorter access latency. A connection activity level is determined for current connections between multiple mobile terminals and a base station. A current data processing load in the base station associated with the mobile terminal control signaling is calculated. A decision is made whether one or more of the mobile terminals is likely to request a handover of its respective connection to a neighboring base station. Based on the current load, the likelihood of requesting handover of the respective connection, and the connection activity level determined for the respective connection, a decision is made whether to terminate the respective connection.
Abstract:
A method (600) for use in a wireless communications system (100) in which there is at least a first node (110) which controls the traffic to and from user terminals (130, 140) in a cell (120) within the system, so that there is downlink traffic in the system. The first node (110) transmits downlink traffic in radio frames, each of which comprises sub-frames. The first node (110) performs measurements on pre-defined system indicators in at least the first cell (120), and based on the results of the measurements, the first node is allowed to autonomously decide (615) to vary the number of available down link sub-frames used for down link traffic in the down link radio frames and also to vary (620) the content of the down link sub frames which are used, the decision being valid (625) for a time which is specified by the first node (110).
Abstract:
The invention relates to an arrangement (130) in a radio base station (10) for handling data traffic within a cell of the radio base station (10), which radio base station (10) is comprised in a telecommunications network. The arrangement comprises a determining unit (131) arranged to determine a maximum power, which maximum power indicates available power to radio base station (10). In addition, the arrangement comprises a comparing unit (132) arranged to compare the maximum power to a threshold power value, and a handling unit (133) arranged to handle data traffic served by the radio base station (10) according to a shaper rule when the maximum power is below the first threshold power value. The shaper rule is defined to handle data traffic in such a way that an amount of data traffic transmitted over a time period is reduced consuming less power of the radio base station (10) than if the data traffic is handled according to a basic rule when the maximum power is above the threshold power value.
Abstract:
In a radio communication network having one or more active cells, a basic idea is to request (S1) signal strength measurements in an area of at least one passive other cell of a radio base station currently not transmitting any cell-defining information for the passive cell. Based on received information representative of the requested signal strength measurements, at least one passive cell is selected (S2) for activation, and the selected cell is then requested to be activated (S3) by causing the corresponding radio base station managing the selected cell to start transmission of cell-defining information to assist user equipment in finding the cell. In this way the invention allows cells to stay passive for as long as possible to reduce power consumption, and allows passive cells to be activated when needed to ensure satisfactory communication services for the users.

Nodes/sites of a radio access network have power utilization and power backup facilities and capabilities suitable for particularized node operation. Features of the nodes/sites and/or of the radio access network include power load control; intermittent charging of batteries; controlled (e.g., slow) charging of batteries; and multiple power backup banks.
Abstract:
A network reconfigurator (26) is provided for use in a telecommunications network (20) comprising a network (24) of radio base stations (28) configured for providing radio access service to the telecommunications network for wireless stations (30). The network reconfigurator is arranged or configured, for differing service outages attributable to differing downed radio base stations (28) of the network of radio base stations, to coordinately and dynamically change modifiable characteristics of plural remaining base stations for at least partially compensating for the service outages. Preferably the reconfigurator (26) is configured, for differing service outages, to dynamically change differing modifiable characteristics of differing plural remaining base stations for at least partially compensating for the service outages. Modifying a characteristic of the plural remaining base stations can include modification of one or more of the following: antenna tilt of at least one of the plural remaining base station; power of a downlink common control channel of at least one of the plural remaining base stations; composition of a neighbor list of at least one of the plural remaining base stations; a parameter pertaining to one of handover, cell power, and cell size for the at least one of the plural remaining base stations.
