20110009160 | Method And Apparatus For Discovering A Home Link In Mobile IP - The present invention provides a method and apparatus for discovering a home link in mobile IP, wherein the method includes: an access network assigns an address for a UE when the UE is attached to the network; the UE acquires a home address from the network; the UE compares the address assigned by the access network with the home address, and confirms that the UE is attached to the home link in the case that the address assigned by the access network and the home address are the same. Therefore, with the present invention, it is not necessary to configure the UE in advance, and the participation of the user is also not required. Thus improved application flexibility is provided. | 01-13-2011 |
20120135701 | Method and system for paging an emergency service user - The present disclosure discloses a method for paging an emergency service user. When a mobility management unit is configured to support the paging optimization in a core network, the mobility management unit does not perform paging optimization when a UE has an emergency bearer service. That is to say, a paging message is sent to all base stations (including the CSG-mode home base station that does not authorize the UE) in the paging tracking list registered by the UE. A core network gateway can notify the mobility management unit of whether the UE has an emergency bearer service. Alternatively, the mobility management unit configured to use the paging optimization, after learning that the service data is to be sent to the UE, checks the current service type of the UE to determine whether the UE has an emergency bearer service. Accordingly, the present disclosure further discloses a system for paging an emergency service user. The present disclosure solves the problem that the mobility management unit and home base station gateway using the paging optimization cannot page the UE which uses the emergency service, so as to increase the success rate of establishing communications and improve the user experience. | 05-31-2012 |
20120140368 | Hardware Overvoltage Disconnecting Circuit - A hardware overvoltage disconnecting circuit wherein a DC power supply module is disconnected from a power network when the AC power network is in the state of overvoltage. The circuit includes a disconnecting relay and a voltage detection circuit. The disconnecting relay is connected in series between an AC power network and a power factor correction circuit of a power supply module. A first sampling terminal of the voltage detection circuit samples the voltage of the AC power network between the AC power network and the disconnecting relay, and an output of the voltage detection circuit is connected to a control terminal of the disconnecting relay. When the AC power network is in the state of overvoltage, the disconnecting relay is disconnected and the power supply module is disconnected from the AC power network. When the voltage of the AC power network is normal, the disconnecting relay is connected. | 06-07-2012 |
20120210392 | ACCESS METHOD AND ACCESS DEVICE - An access method and an access device are provided in the invention, and the method includes the step of: an Authentication, Authorization and Accounting (AAA) server sending indication information to a Wireless Local Area Network Access Network (WLAN AN), wherein the indication information is used for indicating that the WLAN AN determines the direct accessing by a user equipment to the Internet without passing through an Evolved Packet Core (EPC) network. The user experience can be improved by the invention. | 08-16-2012 |
20120231760 | Evolved Packet System and Method for Processing Emergency Call Attachment Thereof - The disclosure discloses an evolved packet system and a method for processing an emergency call attachment thereof, wherein the method comprises: a NodeB selects one PLMN from those Public Land Mobile-communication Networks (PLMN) supporting emergency calls according to an emergency call request message received from a UE which is in a restricted state; the NodeB sends information of the selected PLMN to the UE through a Radio Resource Control (RRC) connection establishment message; and the UE uses the information to establish attachment with the selected PLMN. In the disclosure, it can be ensured that the PLMN to which the User Equipment (UE) selects to attach supports an emergency call, and it can be ensured that Kasmes generated by the UE and the Mobility Management Entity (MME) are consistent during the Authentication and Key Agreement (AKA) flow, so that the success of the emergency call can be guaranteed. | 09-13-2012 |
20120282941 | Method and system for synchronizing user data - A method for synchronizing user data is provided, which includes: when a User Equipment (UE) moves into a coverage area of a new mobility management unit, an old mobility management unit sends an indication of whether a bearer modification procedure is to be triggered to the new mobility management unit, and the new mobility management unit determines whether to trigger the bearer modification procedure according to the indication. A system for synchronizing user data is further provided. By means of the technical solution of the method and the system, the situation that a Quality of Service (QoS) used by a bearer in the new mobility management unit does not match with a bearer QoS of an updated subscription data when a user equipment moves into a coverage area of a new mobility management unit can be avoided. | 11-08-2012 |
20130143515 | Method and system for processing prior services - The disclosure discloses a method and a system for processing prior services, the method includes that: an eNB and/or an MME carries a service priority indication in a message sent to a UE in mobile terminating call procedures for CSFB; and the UE sends a GERAN or a UTRAN a priority indication corresponding to a service when the GERAN or the UTRAN initiates the service. With the disclosure, a source network E-UTRAN can take full advantage of an existing message to carry service information to notify a UE, the UE forwards the information to a target network GERAN/UTRAN, so as to avoid failure of a high priority service in the target network. | 06-06-2013 |
20140341203 | Trusted Non-3GPP Access Network Element, and Method for Accessing Mobile Network and De-Attachment - A trusted non-3GPP access network element and a method for accessing a mobile network and detachment are disclosed. The method for accessing a mobile network includes: a TNAN network element receives an extensible authentication protocol (EAP) authentication success message or an EAP authentication success triggering message, and then establishes a session with a packet data network gateway (P-GW) of a mobile network; and the TNAN network element receives an IP address request message from user equipment and then allocates an IP address consistent with the packet data network (PDN) type requested by the user equipment to the user equipment. | 11-20-2014 |
20140355541 | Method, device and system for accessing core network by means of non-3GPP access - A method, device and system for accessing a core network by means of non-3rd Generation Partnership Project (3GPP) access are disclosed, so as to acquire capability information of a User Equipment (UE) and/or capability information of a non-3GPP access system, and decide, according to the acquired capability information, whether the UE transfers information required for establishing an Evolved Packet Core (EPC) session. The disclosure can enhance the capability of the UE to support establishment of an extra Packet Data Network (PDN) connection and service continuity during switching between access systems. Meanwhile, the capability of a peer can be acquired through the UE and a network, so that the network may support normal access by an existing UE and an enhanced UE simultaneously. | 12-04-2014 |
