  • Patent number: 8538325
    Abstract: The technology described in this application provides a way for an O&M node or system to configure, monitor, and manage relay nodes efficiently. A base station serves a relay node in a cellular communications system that also includes the O&M node. A relay node O&M data context for the relay node is established in a memory associated with the base station. O&M data pertaining to the relay node is stored in the relay node O&M data context. The information in the relay node O&M data context is different than O&M data pertaining to the base station. The base station performs, on behalf of the relay node, O&M-related communications using the O&M data in the relay node O&M data context.

  • Patent number: 7881722
    Abstract: Random access coverage is assured while at the same supporting high uplink data rates in a same service area served by a base station. The service area includes first and second co-sited cells. The first co-sited cell is associated with a first uplink frequency, and the second co-sited cell is associated with a second uplink frequency. The first cell allows a lower uplink load and provides a greater coverage than the second cell. The second cell allows a higher rise over thermal (RoT) value than the first cell. Random access channel requests are initially directed to the first cell using the first uplink frequency. One of the co-sited cells is selected for supporting the connection depending on one or more factors. Example factors include a priority associated with the mobile terminal, a capability associated with the mobile terminal, a load situation in the second cell, or radio channel conditions associated with the mobile radio terminal.
