Example embodiments presented herein are directed towards determining a Proxy Mobile Internet Protocol version 6 (PIMPv6) control plane used by a network node peer in an Internet Protocol version 4 (IPv4) transport network. The example embodiments provide a mechanism in PMIP protocol stack, to allow a Mobility Access Gateway/Local Mobility Anchor (MAG/LMA) node such as SGW (which may be supporting both PMIP draft and PMIP RFC) to decide which PMIP protocol stack shall be used to communicate to the peer node, i.e. LMA/MAG.

A method and apparatus for routing packets from a home agent to a user equipment through a first access network and a second access network. The method includes sending a first binding update message from the user equipment over the first access network to create a first binding cache entry at the home agent. The user equipment uses a home address assigned to the user equipment as a source IP address of the first binding update message. The method further includes sending a second binding update message from the user equipment over the second access network to create a second binding cache entry at the home agent. The user equipment receives packets from the home agent through the first access network and the second access network based on the first binding cache entry and the second binding cache entry.

A method for receiving a trip path including a plurality of passage places calculated by a server according to an embodiment of the present invention includes the steps of: enabling a terminal to send a request for a trip path including a plurality of passage places to the server, the request containing an indicator for representing the request for the path including the plurality of passage places from the server, wherein if the proposed trip path consists of a plurality of sub-paths, and thus the information of a proposed trip path contains the information indicating the sub-paths of the first sub-path is received through the link for the first sub-path, and the information of the first sub-path may include an indicator indicating whether there exists a second sub-path subsequent to the first sub-path, and a link for the second sub-path.

Embodiments of the present invention relate to the field of communications technologies and disclose a data processing method, apparatus, terminal, mobility management entity, and system, so as to reduce data transmission resources and avoid bringing an economic loss to a user. The method in the present invention includes: detecting a status of a data switch of a terminal, where the status includes a disabled state or an enabled state; and sending, by the terminal, a public data network PDN disconnection request to a mobility management entity MME after the status of the data switch is changed from the enabled state to the disabled state, where the PDN disconnection request carries information about a data bearer corresponding to a data domain access point name APN, and the PDN disconnection request is used to trigger the MME to delete the data bearer corresponding to the APN.

Disclosed in the present disclosure is a method for realizing wireless network convergence. The method comprises: constructing a convergence link table in an AP of a wireless network cell; arranging a user management system in an external network; when cross-cell movement of a user station occurs, the user management system configuring convergence link tables in corresponding access points (APs) of two cells; and based on the configured convergence link tables, data transmitted by the user station in an original cell being transmitted in a new cell, thereby realizing wireless network convergence.

A control plane (CP) entity is to adaptively reroute user plane traffic of a mobile node (MN) with use of a segment routing (SR) for IPv6. A message indicating an attachment of the MN to the mobile network is received selecting a first user plane (UP) anchor node. A first set of home network prefixes (HNPs) are allocated to the MN. An IP traffic flow using a first HNP prefix is established between the MN and a correspondent node (CN) along a first network path—defined at least in part by the first UP anchor node and an anchor node of the CN. In response to a handover of the MN, a message indicating a subsequent attachment of the MN is received selecting a second UP anchor node. The second UP anchor node is instructed to host the first HNP prefix previously allocated by the first UP anchor node.

Aspects of the present disclosure provide systems and devices for providing power to one or more remote radio heads used in telecommunications. Some aspects provide a power supply system comprising a first power supply and a plurality of second power supplies configured to be installed in a rack shelf. Each of the plurality of second power supplies is configured to receive a first power signal from the first power supply and provide a second power signal to a respective remote radio head from a plurality of remote radio heads, and at least first inputs to each of the plurality of second power supplies may be ganged together.

A method operative in conjunction with a cellular communication network having a core element and comprising providing moving relays including base and mobile station functionality and a relay resource manager, all co-located, including providing an emergency moving relay from among the moving relays further including a simulated stationary network that includes a simulated IP connectivity gateway communicating with a simulated mobility management entity. The simulated stationary network simulates a stationary network's operation; the emergency moving relay being a root of a sub tree that includes moving relays and mobile stations, and is configured to utilize its mobile and base station functionalities and relay resource manager for operating in: (i) normal mode: emergency moving relay communicates with other relays in the network and with the stationary network; (ii) emergency mode, including, in response to an emergency event, finding new networks to connect to.

A disclosure of the present specification provides a method for processing a NAS request message by an MMF node. The method may comprise the steps of: when it is identified that an NAS request message has been received through a second access network, checking whether a first MM context and a first security context are included therein; and acquiring a second security context from an authentication CP node, and generating a second MM context.

A method for emergency communication includes encoding a message for visual display including a message to field and a message from field. The visual display is revealed to a reading device in communication with a broadcast center, which stores the visual display. The messages are decoded and sorted from visual displays at the broadcast center. On an index channel, a time and channel number for when a message body of the message will be broadcast on a message channel is broadcasted. The message body is broadcasted on the message channel.
