Abstract: Provided is a blocking-type surge protector for accelerated turn-off, comprising: a first transistor (M1), a drain electrode thereof connected to a first port; a second transistor (M2), a drain electrode thereof connected to a source electrode of the first transistor (M1), and a source electrode thereof connected to a gate electrode of the first transistor (M1), the source electrode thereof being further connected to a second port; a first resistor (R1), connected between the drain electrode of the first transistor (M1) and the gate electrode of the second transistor (M2); and an accelerated turn-off module (10), connected between the drain electrode of the first transistor (M1) and the gate electrode of the second transistor (M2).

Abstract: One method for establishing a data connection includes establishing a first data connection between a mobile communication device and a wireless network. The method also includes sending a request to a remote server via the first data connection to retrieve data for establishing a local data connection between the mobile communication device and a communication network, said request including information relating to an identification card of the mobile communication device. The method includes receiving said data from the remote server. The method also includes re-establishing a local data connection between the mobile communication device and the communication network based on said data as received from the remote server.

Abstract: A method for controlling data communication includes receiving a request to register a terminal to a communication network, allocating a virtual card to the terminal for data communication, acquiring data usage information of the virtual card, and controlling use or reallocation of the virtual card according to the data usage information. The data usage information includes an amount of data consumed by the terminal through using the virtual card.

Abstract: Disclosed are apparatuses, methods, systems, and program products for establishing a local connection in a roaming location. The communication method is applied in a mobile communication device, wherein the mobile communication device is able to perform a service transmission in a circuit switched domain within a first communication network. The communication method includes detecting a user terminal at a roaming location, obtaining user identity information over a first communication network of a home location and a second communication network of the roaming location, registering the user identity information with the second communication network of the roaming location, and establishing a localized connection between the user terminal and the second communication network based on the registered user identity information.

Abstract: This invention discloses a communication methods, servers, and terminals. Aspects receive an allocation request, used for registering and connecting to the communication network, of an identity identifier from a terminal; parse the allocation request of the identity identifier and acquiring an attribute information of the identity identifier; find, from a plurality of identity identifier candidates, an identity identifier matching with the attribute information of the identity identifier and regard the found identity identifier as the one to be allocated; read the data, used for registering and connecting to the communication network, of the to-be-allocated identity identifier, and send the data, used for registering and connecting to the communication network, of the to-be-allocated identity identifier to terminals.

Abstract: An information processing method, an electronic apparatus, and a server are described.
