  • Publication number: 20120106423
    Abstract: The basic idea of the present invention is to let the base station enter a low-power, low-radiation cycle, the so called “sleep mode”, when there are no UEs using it and to introduce methods to “wake up” the base station from this state when there is a UE in the vicinity which is allowed to access the base station and which may need it on short notice.

  • Publication number: 20120106488
    Abstract: The present invention relates to methods and arrangements for introducing an automatic one-time configuration ;of the DNS server(s) when a base station gateway, such as an HeNB GW, is deployed, such that the FQDN-to-HeNB GW IP address translation data is proactively configured. This is performed to identify the base station gateway address to which subsequently deployed base stations will be connected. That is, the FQDN-to-HeNB GW IP address translation data for the HeNB IDs of all the HeNBs that may potentially connect to the HeNB GW is proactively configured in the DNS server(s), thereby avoiding frequent and constantly ongoing DNS configuration during normal network operation. This configuration of the DNS allows the eNB to obtain the destination address for an X2 connection without knowing about an eventual HeNB GW, nor the addressing details, such as size/length (or fixed number of bits) of the HeNB GW ID.

  • Patent number: 8125968
    Abstract: A Generic Access Network Controller (GANC) for providing both location and charging information from a Generic Access Network (GAN) to a core network. During registration of a mobile station (MS) the GANC determines a Charging Cell Global Identity (Charging-CGI) and a Location Cell Global Identity, (Location-CGI) for the MS and stores the CGIs in an MS context. The MS sends to the GANC, a request to establish a signaling connection, and includes an Establishment Cause IE indicating a reason for the connection. The GANC selects from the MS context, either the Charging-CGI or the Location-CGI based upon the Establishment Cause IE, and sends the selected CGI to the core network in a message triggering a signaling connection.

  • Patent number: 8107964
    Abstract: In a radio access network (24) a femto radio base station (28f) comprises a resident receiver (54) which acquires system information broadcast in a radio access network (24). At least part of the system information is used for building, at the femto radio base station (28f), a neighbor data structure (59) comprising information for neighboring cells. The neighbor data structure (59) is then used for building a neighbor list. The neighbor list is subsequently transmitted from the femto radio base station (28f) to a user equipment unit (30) served by the femto radio base station (28f). In some example embodiments and modes, the femto radio base station (28f) reports the neighbor data structure to a network node (26, 100) other than the femto radio base station. The other node (26, 100) uses the neighbor data structure for building the neighbor list at the other node.

  • Publication number: 20120003974
    Abstract: In a Circuit Switched Services over Long Term Evolution via Generic Access Network, CSoLTEvGAN architecture (600), relations between E-UTRAN cells (9201) and Generic Access Network, GAN cells (9101) are configured manually in a generic access node controller, GANC (910). This may become a tremendous burden for the operator. The current invention overcomes this by automatically build the needed relations. This is accomplished by determining at the GANC (910), cell identification information for an E-UTRAN cell (9201) and cell identification information for a GERAN or UTRAN cell (1101) overlaying the E-UTRAN cell (9201). The GAN cell (9101) is determined based on the cell identification information for the GERAN or UTRAN cell (1101). An entry within a translation table (1000) is created so that the cell identification information for the E-UTRAN cell (9201) is mapped to the cell identification information for the GAN cell (9101), or vice versa.

  • Publication number: 20110294499
    Abstract: Localized areas within a cell of a cellular wireless communication network, wherein users experience high traffic loads or poor coverage, are automatically detected and positioned by a network-based monitoring and positioning method. The localized areas are detected by performing measurements (e.g., TAdv, AOA, and neighbor node measurements) on User Equipment (UE) indicating or recording a network capacity or coverage deficiency. The detected, localized area of deficient performance is then positioned (e.g., in latitude and longitude), such as by positioning one or more UE within the area. The deficient network capacity or coverage, the localized area in which it is concentrated, and the position of the localized area are then reported, with a recommendation to deploy a low-power serving node within the localized area (e.g., at or near the area reported position) to alleviate the capacity or coverage deficiency, while minimizing interference with communication services to other users within the cell.

  • Publication number: 20110269499
    Abstract: The present invention relates to methods and arrangements in a wireless communication system that enable a load balancing procedure in a network with HeNB GWs. The problem of the ineffective conventional load balancing procedure when used in a network with HeNB GWs, is addressed by a solution where the HeNB includes (510) an explicit indication of the reason for radio link establishment (load balancing establishment cause) in the S1AP INITIAL UE MESSAGE message (511) used to establish the S1 signaling connection associated with a user equipment to an MME, so that the HeNB GW (550) can perform an accurate MME selection based on the knowledge that the establishment is due to load balancing, i.e. an MME selection that realizes the required inter-MME load balancing.
