Linked micromechanical positioning apparatus for real-time testing and measurement

A device or a system for measuring muscle signals. A system may include at least one processor, memory including computer program code, the memory and the computer program code configured to, with the at least one processor, cause the system to perform at least the following: measure a signal from a muscle to obtain a muscle activation signal; carry out at least one transform on the muscle activation signal to obtain a muscle activation spectrum; and determine a muscle state indicator from the muscle activation spectrum by using signal characteristics from a first and a second band of the muscle activation spectrum.

Device for measuring muscle signals

An approach is provided for building a scalable service platform by initiating transmission of encrypted data from a public network cache. An access control server platform determines a first authorization key for a user and a second authorization key for a resource, and then encrypts the resource with the second authorization key, and encrypts the second authorization key with the first authorization key. The access control server platform initiates distribution of the encrypted second authorization key with the encrypted resource over a network. The access control server platform further initiates caching the encrypted second authorization key with the encrypted resource that meets a predefined threshold value (e.g., a data size, an access frequency, a modification frequency, or an auditing requirement) in a cache in the network, and initiates transmission of the cached and encrypted second authorization key with the cached and encrypted resource from the cache to at least one authorized entity.

Method and apparatus for providing a scalable service platform using a network cache

The invention relates to method applicable in a packet-switched cellular network for voice connections, by which method a new dedicated channel can be established quickly using the existing dedicated channel of the voice connection. The establishment of the new dedicated channel utilizes the previous dedicated channel the existence of which is extended by sending to at least the receiving terminals post-speech packets according to the invention. The post-speech packets produce a 2-second delay, approximately, which is sufficient to establish a new dedicated channel between terminals participating in a session.

Method for establishing packet-switched connection, and cellular network utilizing the method, and cellular terminal

A method for setting up data sessions in a communication system is provided. The method comprises registering at least one user equipment with a service provider where after information about media capabilities is communicated between the at least one user equipment and the service provider and then stored. The method comprises further sending a request for a data session with at least one user equipment and using the stored information when setting up the requested data session. A communication system, an application server and a user equipment configured to operate accordingly are also provided.

Setting up communication sessions

An approach is provided for service provider controlled communication security. A security platform receives a connection request from a client device. The security platform determines context information associated with the device, access network, a user of the device, or a combination thereof, and then processes and/or facilitates a processing of the context information to determine one or more encryption ciphers to offer for the session. Next, the security platform causes, at least in part, establishment of the connection request using, at least in part, the one of the offered encryption ciphers.

Method and apparatus for providing service provider-controlled communication security

An approach is provided for optimizing message routing without repeatedly resolving a home location. A login request from a user equipment associated with a resource identifier is received. The user equipment is configured to operate within a network including a plurality of clusters. The resource identifier of the user equipment is modified to include home cluster information indicating a corresponding one of the clusters serving the user equipment.

Method and apparatus for message routing optimization

An approach is presented for authenticating access by a service. The server receives a request, from a service, for the server, wherein the request includes, at least in part, a service-specific secret or a derivation of the service-specific secret. Further, the server determines to generate a server-computed secret. Then, the server determines to authenticate the request based, at least in part, on a comparison of the service-specific secret or the derivation of the service-specific secret against the server-computed secret or a derivation of the server-computed secret. The service receives credentials from a credential manager. The secret is part of the credentials. The credential manager and the server share some secret pre-configured data like key tables. The generation of the service specific secrets is based on the shared data.

Method and apparatus for authenticating access by a service

An apparatus and a method are provided for multiplexing different sessions using the same authorized contexts for media. The method includes distinguishing different control plane sessions by a user equipment, and identifying media flows of a same application among the different control plane sessions by the user equipment by setting a service identifier. The method further includes sending the service identifier by the user equipment to a call state control function including a policy decision function, and authorizing quality of service for a user plane context by the policy decision function. Furthermore, the method includes enabling, by the policy decision function based on the service identifier, the different control plane sessions with media flows of the same application to share the same user plane context with the authorized quality of service to multiplex the different control plane sessions with media flows of the same application.

Multiplexing media components of different sessions

The invention relates to a method for transmitting a television data stream via a wireless network connection. The method comprises receiving at least one television data stream via the User Datagram Protocol (UDP); converting the at least one UDP television data stream into a Transmission Control Protocol (TCP) data stream; and transmitting the TCP data stream via the wireless network connection over a point-to-point link.

Method and device for wireless transmissions of internet protocol TV

An approach is provided for determining an optimal keep-alive time period. A request is received from one of a plurality of user equipments for a keep-alive timer value. A specific network information related to a network serving the one user equipment is determined. A keep-alive timer value is determined based on the network information and advantageously using statistical analysis.

Method and apparatus for a keep alive probe service

A session set-up for communicating data via a data network is disclosed. First, a session establishment between a communication apparatus and a serving entity is requested for a service from the serving entity supporting the service. Then, when a requirement of a user connection for the service is determined, an association with a data network for the service is activated via a core network.

Session set-up for time-critical services

The invention relates to a method for ensuring the adequacy of transmission capacity in a digital packet-switched cellular network where both voice sample packets and associated header fields are transmitted in real time in one and the same transmission channel. The invention also relates to a terminal employing the method. In the method, the contents of voice sample packets at the beginning of a speech spurt are partly replaced by packet header field data in situations where the combined bit count of voice sample data and packet header data exceeds the transmission capacity of the transmission channel.
