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.

Method and system for controlling access to shared network

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.

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 (S); the group policy is applied in the IP-CAN session (S). 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.

Policy application method for machine type communication, and policy and charging enforcement function

A method for controlling access of machine type communications device is provided by the present invention. The method includes: configuring an access priority to a machine type communications device; a network side configuring a corresponding access control parameter for an access priority needing an access control according to the current network load information, and sending the access priority needing the access control and the access control parameter to the machine type communications device; and according to an access priority of the machine type communications device and the received the access priority needing the access control and the access control parameter, the machine type communications device judging whether an access request can be initiated. A system for controlling access of the machine type communications device is also provided by the present invention.

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.

Method and system for session modification

A method and an apparatus for creating an Internet Protocol Connectivity Access Network (IP-CAN) session are disclosed herein. The method includes: creating, by a First Policy and Charging Enforcement Function entity, PCEFa entity, a session with a Policy and Charging Rules Function entity, PCRF entity; performing, by the PCEFa entity, mobility registration with a second Policy and Charging Enforcement Function entity, PCEFb entity; creating, by the PCEFb entity, a session with the PCRF entity; and sending, by the PCRF entity, a session information to the PCEFa entity and the PCEFb entity. mobility The apparatus includes: a PCEFa entity, a PCEFb entity, and a PCRF entity. The method and the apparatus for creating an IP-CAN session under the present disclosure accomplish the purpose of creating an IP-CAN session in the new PCC architecture.

Method and apparatus for creating IP-CAN session

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 policy and charging enforcement function (PCEF) b 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 the PCEF a according to a PCC rule response message received from the PCEF b. 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.

A method for sharing network resources includes: setting a sharing group based on service types in the process of setting up a bearer and determining a maximum network resource for the sharing group; and allocating a resource for the bearer in the range of the maximum network resource. The present invention also provides a system and an apparatus for sharing network resources. The embodiments of the present invention implement the sharing of a maximum transmission rate among multiple bearers in an evolved network, solve the problem of low network resource utilization caused by the fact that each bearer occupies a fixed bandwidth resource, and implement maximum utilization of network resources.
