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 |
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 |
20150280927 | Method, system, and controller for routing forwarding - A method and system for routing forwarding are described. The method includes: a controller sends pre-generated routing flow tables to an Evolved Universal Terrestrial Radio Access Network (UTRAN) NodeB (eNB) and an Access Gateway (AGW) respectively; and the eNB and the AGW distribute data according to the received routing flow tables respectively. A controller for routing forwarding is described. According to the disclosure, the controller sends the routing flow tables to the eNB and the AGW, so that the extended OpenFlow protocol can be applied to an Evolved Packet System (EPS), network upgrading cost is lowered, network upgrading can be simplified, and a network upgrading period can be shortened. | 10-01-2015 |
