  • Patent number: 9706475
    Abstract: A core network node may send an overload indicator capable of distinguishing PLMNs to an access network node when the core network node is overloaded; and the access network node may learn a PLMN over which access control needs to be performed according to the overload indicator received. PLMNs are distinguished in access control according to an actual situation of overload of the network node caused by a PLMN sharing the network, ensuring fairness in access control over terminals of all PLMNs sharing the network.

  • Patent number: 9301202
    Abstract: The disclosure discloses a method and system for controlling access to a shared network. In both the method and the system, a core network node may send an overload indicator capable of distinguishing PLMNs to an access network node when the core network node is overloaded; and the access network node may learn a PLMN over which access control needs to be performed according to the overload indicator received. The method and the system of the disclosure distinguish the PLMNs in performing access control according to an actual situation of overload of the network node caused by a PLMN sharing the network, ensuring the fairness in performing access control over terminals of all PLMNs sharing the network. Therefore, the problem of unfairness in performing access control over terminals of different PLMNs in a network sharing scenario is solved.

  • Patent number: 8885568
    Abstract: A policy application method for Machine Type Communication (MTC) and a Policy and Charging Enforcement Function (PCEF) are provided by the disclosure. The method comprises that in a course in which an MTC device attached to a PCEF establishes an Internet Protocol-Connectivity Access Network (IP-CAN) session, the PCEF locally obtains a group policy corresponding to a device group to which the MTC device belongs (S302); the group policy is applied in the IP-CAN session (S304). The technical solution of the disclosure reduces the time required by applying the MTC policy by the PCEF, saves network resources, and increases utilization of the network resources.

  • Patent number: 8601533
    Abstract: A method and system for session modification are provided. The method includes these steps: A home policy and charging rules function (h-PCRF) sends a policy and charging control (PCC) rule providing message to a first policy and charging enforcement function (PCEF) according to a received PCC rule request message, an application layer service message, or an h-PCRF self-trigger event; and the h-PCRF sends a PCC rule providing message to a second PCEF according to a PCC rule response message received from the first PCEF. With this present disclosure, session modification may be implemented when two or more PCEFs are included in the PCC architecture of a system architecture evolution (SAE) system.
