摘要:
This document discloses a solution for preparing for a connection establishment in a wireless network. According to an aspect, transmission of a request message from the wireless apparatus is carried out on a channel. Thereafter, a response message is acquired on said channel as a response to the request message, the response message being originated from a second wireless apparatus which is in an unassociated state with said wireless apparatus, and the response message comprising information on at least two wireless networks operating on at least one of said channel and another channel. Then, the received response message may be utilized in the connection establishment.

This document discloses a solution for transmitting scanning response messages in an orderly manner in a wireless network. An access node determines a transmission order for a plurality of access nodes responding to a scanning request message provided by a scanning/requesting device. Then, the access node determines its own transmission turn within the transmission order and transmits a scanning response message with reduced channel contention. Another aspect relates to the scanning device arranged to receive the scanning response messages where the scanning device monitors the transmission order of the scanning response messages.

Method, apparatus, and computer program product embodiments of the invention are disclosed to automatically advertise a change in service offering of a wireless first device in wireless networks. In an example embodiment of the invention, if there is a change in service offering of the first device that is connected to a wireless second device, the first device automatically generates a reassociation request frame and transmits it to the second device. In addition to the standard processing of the reassociation request frame, the second device considers the received reassociation request frame as a trigger to respond by transmitting a generic advertisement service request to the first device. The first device will then have an opportunity to transmit its updated and up-to-date service description to the second device in a generic advertisement service response frame. The second device buffers the first device's updated service description and makes it available to other wireless devices searching the network for services, to facilitate network selection.

A method, apparatus, and computer program product are provided for facilitating randomized port allocation. An apparatus may include a processor configured to receive a port allocation message from a network management entity. The port allocation message may comprise an encryption key, an initial input value, and a value indicating a number of ports allocated to the apparatus for communication on a network. The processor may be further configured to calculate at least one port allocated to the apparatus with an encryption function based at least in part upon the encryption key and initial input value. Corresponding methods and computer program products are also provided.
摘要:
A security gateway/home agent controller HAC is used to assign one home agent HA from a plurality of HAs and to identify at least one security protocol that is common between a mobile node MN and the assigned HA. Establishment of a security association between the MN and the assigned HA is enabled according to the identified security protocol and utilizing bootstrapping parameters provided over a secure connection between the security gateway/HAC and the MN. The bootstrapping parameters include at least a home address for the MN, an address of the assigned HA and security credentials and security parameters for the identified at least one security protocol. In an exemplary embodiment the home address for the MN may be an IPv6 home address and the MN may have certain capabilities with respect to security protocols and ciphering suites which the MN sends to the security gateway.

Systems and techniques for managing local communication between a network access point and a host device. Upon connection by a host device to an access point, a local connection link is established between the access point and the host device. A network connection may be established between the access point and the host device, with the network connection being able to pass through the host device to enable communication with and beyond an access network to which the access point provides a connection. Local messages may be passed between the access point and the host device over the local connection link, separately from and independent of communication that may occur over the network connection.
