    摘要: Method for handling failure of a MME (Mobility Management Entity) in a Long Term Evolution/Evolved Packet Core network or an Evolved Packet System, wherein multiple UEs (User Equipment) are attached to a first MME, which stores first context information representing the UEs attached to the first MME, the UEs are connected to one of multiple eNBs (evolved NodeB), the eNB may communicate with the first MME and with at least one neighboring MME, and the UEs may communicate with the first MME and with the at least one neighboring MME via the eNB, includes: detecting failure of the first MME, gathering information related to UEs attached to the first MME, restoring parts of the first context information at one or several of the neighboring MME using the gathered information, and re-establishing network internal logical connections with the one or several of the neighboring MME using the restored first context information.

    摘要: A method for supporting selection of PDN connections for a mobile terminal, in particular in decentralized mobile operator networks, wherein the mobile terminal is connected to an access point, wherein the mobile terminal is in active mode having at least one ongoing IP session to a Packet Data Network (PDN) via a PDN gateway-first PDN gateway-, wherein monitoring whether a more suitable PDN gateway-second PDN gateway-than the first PDN gateway becomes available for the mobile terminal is performed, and wherein in case of detecting the second PDN gateway, any new IP session of the mobile terminal to the PDN is established by initiating a new PDN connection to the second PDN gateway, while an already ongoing session associated with the existing PDN connection to the first PDN gateway is kept. Furthermore, a mobile terminal with PDN connection selection support is disclosed.

    摘要: A reliable and flexible method for controlling traffic within a network structure without the addition of remarkable complexity to the core network is provided, the structure including a PDN (Packet Data Network), an operator core network with a DNS (Domain Name System) server, a HeNB (Home evolved Node B) or HNB (Home Node B) and/or eNB (Evolved Node B) or NB (Node B) and a UE (User Equipment) that is associated with the HeNB or HNB and/or eNB or NB. On the basis of a predefinable routing policy the DNS server is controlling whether a traffic from a UE to a destination address within a local network associated to the HeNB or HNB or eNB or NB or within a PDN and/or vice versa will be routed via the core network or directly via the local network in support of local network protocol access or selected network protocol traffic offload.
