  • Patent number: 8391238
    Abstract: The disclosure relates to automatically configuring a map of inter-access technology neighbor relations. In this neighbor relations map configured by an ANDSF, relationships between neighboring cells of differing access networks of the same or different access technologies are maintained including extra-domain and non-domain neighbor relationships. A domain refers to a domain of one or more access technologies in which ANDSF is not required for intra-domain access selection and discovery. ANDSF configures the map based on neighbor relations data reports from wireless terminals, which record the neighbor relations data as they perform extra-domain or non-domain handovers or reselections or as they scan their surroundings. ANDSF provides steering instructions to configure the neighbor relations data recording and reporting behaviors of the wireless terminals.

  • Publication number: 20120165022
    Abstract: In a method and an apparatus for indicating problems data from, typically automatically, entered cell relations is compared to site location information and mobile measurements, if available. An indication of a possible problem is triggered if the comparison indicates that the cell added as neighbours are not suitable as defined by one or many threshold functions. In accordance with one embodiment method of problem indication generation in a cellular radio system is provided. An apparatus receives a neighbor cell relation entries and site location information. The received information is compared and a problem indication is generated if the comparison indicates that cells entered neighbour cells are not close to each other as defined by at least one threshold values.

  • Patent number: 6693894
    Abstract: A method and communications network is provided that directly routes a call from a calling party to a called mobile party using an IP network. More specifically, the method includes the step of determining at the IP network as to whether the called mobile party is currently roaming outside a home mobile network. In response to an affirmative determination, an address of a destination mobile network currently occupied by the called mobile party is obtained at the IP network, and the call between the calling party and the called mobile party is connected using the IP network and the destination mobile network while bypassing the home mobile network. In response to a negative determination, an address of the home mobile network is obtained at the IP network, and the call between the calling party and the called mobile party is connected using the IP network and the home mobile network.
