摘要： The present invention discloses methods and systems for selecting at least one SIM card for data communication at a wireless communication device which is capable of housing a plurality of SIM cards. When a switching condition is satisfied, the wireless communication device selects a second SIM card group, and disconnects one or more connections established using any non-second group SIM card. Non-second group SIM cards are SIM cards that are not in the second SIM card group. A selected SIM card from the second SIM card group is then used for data communications. The steps are repeated until (i) the switching condition is no longer satisfied, (ii) no more SIM cards selected from the second SIM card group can be used for data communications or (iii) no more connection is made using non-second group SIM cards.

摘要： The present invention discloses a method and system for configuring an electronic device through a management device. When the management device is coupled to the electronic device and the electronic device is not able to communicate with a server, the method and system detect an identity of the electronic device and configure the electronic device according to the identity with a configuration. The configuration may further comprise authentication information, routing policy, energy policy and any information to configure the electronic device or to configure the management device for electronic device. The method and system also allow the electronic device to send data to and to receive data from the server through the management device. The method and system may also diagnose the electronic device before configuring the electronic device.

摘要： Methods and apparatus for processing data packets originated from a mobile computing device to destinations at a wireless network node. The wireless network node receives an access request from the mobile computing device for the data packet transmission to the destinations and determines an identifier of the mobile computing device. The wireless network node then determines whether the identifier is in a wireless network node database. When the identifier is not in the wireless network node database, the wireless network node suspends to process data packets received from the mobile computing device and communicates with a server to determine whether status of the mobile computing device in a server database is the first state.

摘要： The present invention discloses methods and systems for processing data packets received at a first network node and for processing encapsulating packets received at a second network node. The first network node receives data packets from its network interface. It then selects a first tunnel and selects none or at least one second tunnel according to a selection policy. Original encapsulating packets (OEPs) are transmitted to a second network node through the first tunnel and at least one duplicate encapsulating packet (DEP) is transmitted through the at least one second tunnel. The second network node receives an encapsulating packet with a global sequence number (GSN) through an aggregated connection. The second network node determines whether one or more data packets corresponding to the encapsulating packet have been received earlier. The second network node may then determine whether or not to forward the one or more data packets.

摘要： Methods and systems for forwarding data between a first network element and a terminal at a management server, comprising the steps of receiving a request from the terminal to communicate with the first network element during a first data session; determining whether a first connection has been established with the first network element; establishing the first connection with the first network element if the first connection has not been established with the first network element; and forwarding data between the first network element and the terminal using the first connection during the first data session.

摘要： The present invention discloses methods and systems for managing an error correction mode at a first communications router. The first communication router transmits data packets to a second communications router and stores the first data packet in a local storage medium, When a delay inquiry message is received from the second communications router, the first communications router activates the error correction mode. When the error correction mode is activated, the first data packet is retransmitted to the second communications router and an error correction packet corresponding to the first data packet is also transmitted. When a back-to-normal message is received from the second communications router, the first communications router deactivates the error correction mode. The back-to-normal message indicates that the first communications router no longer needs to be in error correction mode.

摘要： A method and system for processing Domain name Services (DNS) request in a gateway. The gateway receives a DNS request from a host from its local area network. The gateway then selects DNS server(s) and transmits a new DNS request to at least one DNS server(s). DNS server(s) may or may not be accessible through a first tunnel. The contents of the new DNS request are the same as the content of the received DNS request. Further, when the gateway receives a DNS response corresponding to the DNS request, it determines a decision whether to transfer data to the host whose IP address is specified in the DNS response through a second tunnel. The decision may be based on a geographical location of an IP address.

摘要： The present invention discloses methods and systems for sharing data usage by a plurality of SIM cards at a plurality of network devices. Each of the plurality of network devices is capable of housing at least one SIM card from the plurality of SIM cards. The method comprises the steps of determining the total data usage allowance. A remaining total data usage allowance is determined by either retrieving it from a carrier server or by subtracting aggregated data usage information from the total data usage allowance. The method further comprises restricting use of one or more of the plurality of SIM cards when the remaining total data usage allowance is below a first threshold until the remaining total data usage allowance is above the first threshold. The total data usage allowance is changed to a first value periodically or according to an administrator's instruction.

摘要： A method and system for processing Domain name Services (DNS) request in a gateway with at least one local area network (LAN) interface and at least one wide area network (WAN) interface. The gateway receives a first DNS request from a first host via one of the at least one LAN interface of the gateway. The gateway then selects a plurality of DNS servers. At least one of the plurality of DNS server is accessible through at least one tunnel. The gateway transmits a plurality of new DNS requests to the plurality of DNS servers. The contents of the plurality of new DNS requests are the same as the content of the first DNS request.
