20120117257 | Method and Apparatus for Notifying Connection Attributes for Local Internet Protocol (IP) Access - The invention discloses a method for notifying connection attributes of local IP access, comprising in the procedure of establishing a PDN connection, a mobility management element notifying the user terminal of connection attributes of the PDN connection. The invention also discloses an apparatus for notifying connection attributes of local IP access, comprising: a determination unit for determining connection attributes of the PDN connection for user terminal in the process of establishing the PDN connection; a notification unit for notifying the user terminal of the connection attributes of the PDN connection. The mobility management element at the network side of the invention notifies the UE of the type and attribute information of the PDN connection at the same time after determining the PDN connection to be established for UE so as to facilitate the UE determining the corresponding access policy according to the attribute information of current PDN connection when moving. | 05-10-2012 |
20120142278 | METHOD, SYSTEM AND TRANSMISSION DISTRIBUTION NETWORK ELEMENT FOR INDICATING DATA-DISTRIBUTION - The present invention provides a method and system for indicating data offload, and a traffic offload network element, the method comprises: when a radio bearer is established or modified, a mobility management unit of a core network notifies a traffic offload network element of the bearer type of the bearer to determine whether to start the data offload. Through the present invention, the judgment operation of the core network is simplified. In addition, under the situation that the core network side determines whether to start local access function, the traffic offload network element also can correctly start an offload policy. | 06-07-2012 |
20120142311 | Charging System and Method - The present invention provides a charging method, including: a mobility management network element obtaining charging policy information of a terminal from a user subscription data network element; an access network element obtaining the charging policy information of the terminal from the mobility management network element; and the access network element storing the charging policy information of the terminal, and charging for services of the terminal according to the charging policy information. Accordingly, the present invention also provides a charging system, an access network element and a mobility management network element. The technical scheme of the present invention can send the charging policy information to the radio side network element in the LIPA structure to realize the dynamic charging based on users of services; and it can cover the LTE network and the 3G network at the same time. | 06-07-2012 |
20120170495 | Method and apparatus for status transition - A method and apparatus for status transition are provided in the disclosure, which enable a wireless side network element to judge that a service request message is a paging response message after receiving the service request message, transmit an initial user equipment message to a mobility management entity, and indicate that the service request message is valid in the initial user equipment message. The method and apparatus of the disclosure solve the problem that the mobility management entity is unable to make a correct judgment and corresponding logical processing, and improve processing efficiency of the mobile communication system effectively. | 07-05-2012 |
20120207104 | Method for implementing local access and system thereof - The disclosure discloses a method for implementing local access, which includes: after user terminal initiates a local access and a mobile management unit determines that the local connection can be established for the user terminal, the mobile management unit acquires local access gateway information through a Domain Name System (DNS) server. The disclosure further discloses a system for implementing local access, correspondingly. By providing a specific implementation solution of inquiring the local access gateway, the disclosure ensures selection between the core network gateway and the local access gateway according to a respective scenario, thus properly and effectively implementing the local access function implemented by the user terminal through the local access gateway. | 08-16-2012 |
20120207137 | Method for Managing Local IP Access Connection - Disclosed is a method for managing local IP access connection, wherein the method comprises: determining whether a local IP access connection supports mobility; if yes, then processing the local IP access connection, wherein the processing includes at least one of the following: activate, establish and update. According to the present invention, the source/target mobility management entity or source/target RAN node determines whether a local IP access connection supports mobility according to a CSG identifier or local gateway information, which thus achieves the management operation on the local IP access connection, avoids the waste of system resources and the increasing of system burden and improves the processing efficiency of the mobile communication system. | 08-16-2012 |
20120218974 | Method and Device for Managing Internet Protocol Offload Connection - The disclosure discloses a method and a device for managing Internet Protocol (IP) offload connection. The method comprises the steps of: determining that a target Mobility Management Entity (MME) supports IP offload or identifies information of two Serving Gateways (S-GWs); the target MME receiving IP offload connection information from an source MME; the target MME processing the IP offload connection according to the IP offload connection information, wherein the process comprises one of the following: establishing, updating and activating the IP offload connection. With the disclosure, the experience of the user is enhanced in the wireless communication system. | 08-30-2012 |
20120300638 | Method and System for Controlling Establishment of Local IP Access - The present invention discloses a method for controlling establishment of a local IP connection, and the method includes: when an access gateway determines that data or application of a terminal needs to be offloaded, informing the terminal that a local IP connection needs to be established via a mobility management entity and a radio side network element by a bearer modification, or informing a radio side network element or a local gateway of a routing policy via a mobility management entity. The present invention also discloses a system for controlling establishment of a local IP connection. The present invention enables the terminal to instantly acquire whether a local IP connection needs to be re-established, can realize dynamic adjustment of local IP data; meanwhile, the present invention can realize dynamic adjustment of local IP data and dynamic establishment of the local IP connection in the case of the local IP connection. | 11-29-2012 |
