  • Patent number: 11006361
    Abstract: Systems and methods relating to a core network detection mechanism for detecting abnormal signaling patterns for signaling aimed at wireless devices (e.g., low-power consumption wireless devices such as low-power consumption Machine Type Communication (MTC) devices) are disclosed. In some embodiments, a method of operation of a core network node in a cellular communications network comprises receiving signaling aimed at a wireless device, detecting, via a detection mechanism, an abnormal signaling pattern based on the signaling, and taking one or more actions upon detecting an abnormal signaling pattern. In this manner, an action(s) may be made to mitigate increased power consumption at the wireless device due to abnormal signaling.

  • Patent number: 7711824
    Abstract: An access system (ACC1) for relating service providers (SP1-SPn) to users (U11-Um1) includes an edge access server (EAS) connecting the service providers and penults (P1-Pk) connecting the users. User devices (UD11-UD14) are connected via VLAN:s to a user ports (UP11) on the penult. The edge access server has service agents (SA1-SAn), an administrator (AD1) and a broadcast handler (BH1), which forms a handling system together with handlers (H1-Hk) in the penults. A user (U11) decision including VLAN, service (SP1) and user port (UP11) is sent to the administrator (AD1), which dynamically allocates to the relevant service agent (SA1) a MAC address, defining a relation (R11). A user device (UD11) broadcasts a DHCP request unicasted together with user port (UP11) to the braoadcast handler (BH1). The user device (UD11) gets its IP address and IP address to the service agent (SA1). The device (UD11) broadcasts an ARP request which is unicasted by the penult (P1), to get the MAC address to the service agent (SA1).
