Cloud delivered access
Cloud delivered access may be provided. A network device may provide a client device with a pre-authentication virtual network and a pre-authentication address. Next, a policy may be received in response to the client device authenticating. The client device may then be moved to a post-authentication virtual network based on the policy. A post-authentication address may then be obtained for the client device in response to moving the client device to a post-authentication virtual network. Traffic for the client device may then be translated to the post-authentication address.
Predictive roaming between subnets
A network device of a subnet determines predictive roaming information for a wireless client. Predictive roaming information can identify the wireless client and a home network subnet of the wireless client. The network device provides predictive roaming information associated with a wireless client to neighboring subnets. Neighboring subnets store received predictive roaming information, and use the predictive roaming information if the wireless client roams to them.
MULTICAST HANDOVER FOR MOBILE COMMUNICATIONS
Embodiments provide efficient multicast handover for content delivery to client devices in multi-carrier communications systems. For example, client devices in a transport craft can consume a media channel offering via a first carrier during transport through the communications system. Embodiments can establish respective multicast groups for the media channel offering in at least the first carrier and a subsequent second carrier, and can notify the craft of the multicast groups prior to the craft being serviced by the second carrier. Such pre-notification can permit multicast handover of the media channel offering from the first carrier to the second carrier in a manner that avoids typical handover-related. For example, embodiments can direct multicast delivery of the media channel offering to the craft in accordance with the first multicast group while being serviced by the first carrier and in accordance with the second multicast group while being serviced by the second.
Access information handling in a mobile network with cellular network accesses and wireless local area network accesses
A first network node controls WLAN accesses and a second network node controls cellular network accesses. The first network node (NN) records a time of a last radio contact event of a user equipment (UE) with respect to a WLAN access controlled by the first NN. In response to a request from a third NN, the first NN indicates the recorded time of the last radio contact event to the third NN. The second NN records a time of a last radio contact event of the UE with respect to a cellular network access controlled by the second NN. In response to a request from the third NN, the second NN indicates the recorded time of the last radio contact event to the third NN. The third NN can use the indicated times to determine whether the UE is attached to a WLAN access or to a cellular network access.
SEAMLESS MOBILITY IN WIRELESS NETWORKS
AP's associated with a communication network and any wireless devices desiring contact, operated according to a protocol in which each wireless device selects AP's with which to communicate. A system coordinator causes the AP's to operate so as to guide each wireless device to an AP selected by the system coordinator. This has the effect that, notwithstanding that the protocol involves having the wireless device make the selection of AP, functionally, the AP's make the selection for it. In a 1st technique, multiple AP's share an identifier, with the system coordinator directing one particular AP to respond to the wireless device, thus appearing to wireless devices as a personal cell. In a 2nd technique, AP's each maintain identifiers substantially unique to each wireless device, with the system coordinator directing only one particular AP to maintain any particular wireless device's identifier, thus appearing to wireless devices as a personal AP.
PS to CS handover indicator
The present invention relates to a solution for handling handover of connections for a user equipment from a packet switch network to a circuit switched network. This is provided as a method implemented in a node and system. The method is provided in a telecommunications network connecting user equipment, i.e. UE, communicating wirelessly with the network. The method comprising steps of detecting that handover is required from a packet switched, i.e. PS, based network to a circuit switched, i.e. CS, based network, initiating in a source mobility management node, a single radio voice call continuity, i.e. SRVCC, initiating a PS to CS handover for non-voice components with information about voice related parameters and a PS to CS handover indicator, executing hand over, sending an update request to a serving gateway, i.e. SGW, from a target mobility management node with non-voice related parameters and the PS to CS handover indicator, forwarding the update request from the SGW to a packet data network gateway, i.e. PGW, receiving the update request in the PGW, detecting the PS to CS handover indicator, and handling in the PGW the PS to CS handover indicator.
IP ADDRESS MANAGEMENT METHOD AND APPARATUS, IP ADDRESS ANCHOR, AND MOBILE NODE
Embodiments of the present invention relate to the field of communications technologies, and provide an IP address management method and apparatus, an IP address anchor, and a mobile node. The method includes: when detecting that a mobile node (MN) accesses an IP subnet on which an IP address anchor is located, obtaining, by the IP address anchor, a valid IP address prefix being used by the MN; and sending, by the IP address anchor, switchover indication information to the MN according to the valid IP address prefix, so that the MN determines, according to the switchover indication information, whether the accessed IP subnet has changed. The present invention resolves a prior-art problem that an MN cannot determine whether an IP subnet accessed by the MN has changed, thereby achieving a technical effect that an MN can accurately determine whether an IP subnet accessed by the MN has changed.
Method and apparatus for a mobile node to connect different access routers while maintaining a consistent network address
In a Proxy Mobile IPv6 (PMIP) network, a mobile node can roam between different access networks while maintaining a consistent IP address for session continuity. To provide access to a user's home LAN resources, even when the user's mobile node is not directly attached to the home LAN, a local mobility anchor and mobility access gateway are configured to authenticate the mobile node credentials and if authorized, to provide access to the user's LAN resources by via data tunnels and routing table reconfigurations.
System and method for connection rehoming
A method for connection rehoming by a user equipment includes attaching to a first network attachment point (AP) and establishing a first connection to a first packet data network (PDN) interface, and moving from the first network AP to a second network AP. The method includes discovering a first cost associated with the first connection is high, and rehoming the first connection, thereby establishing a second connection coupling the UE to a second network AP and to a second PDN interface, wherein a second cost associated with the second connection is low.
PREDICTIVE AND NOMADIC ROAMING OF WIRELESS CLIENTS ACROSS DIFFERENT NETWORK SUBNETS
Wireless access points detect neighboring wireless access points in different subnets. Upon connecting with a wireless client, a wireless access point determines predictive roaming information for the wireless client. Predictive roaming information identifies the wireless client; its home network subnet; and includes connection information associated with the wireless client. The wireless access point forwards the predictive roaming information associated with a wireless client to neighboring wireless access points while the wireless client is still connected with the wireless access point. Neighboring wireless access points store received predictive roaming information. Upon connecting with a wireless client, a neighboring wireless access point determines if the wireless client matches the stored predictive roaming information. If so, the neighboring wireless access point uses the predictive roaming information to quickly connect with the wireless client and to establish a tunnel to redirect network traffic associated with the wireless client through to its home subnet.
