A communication terminal is described comprising a communication module configured to establish an NAS bearer connection between the communication terminal and a core network of a cellular mobile communication network and a controller configured to control the communication terminal to dedicatedly use the NAS bearer connection to exchange data between at least one second communication terminal communicating with the communication terminal and the core network.

Methods and apparatus that enable a wireless network to detect and manage impending congestion events caused by a plurality of mobile devices attempting to access the network in a brief space of time. In one embodiment, the network comprises a 3g (UMTS) cellular network, and includes a congestion management and avoidance entity that preemptively triggers a collision mode upon detecting an impending congestion event. This mode advantageously reduces processing burden on the base station by causing the mobile devices (UEs) to halt current access attempts, and invoke a multiple access scheme (e.g., wait a random amount of time before attempting further access attempts). The comparatively early detection and avoidance of collisions reduces the mobile device's power consumption, while addressing congestion events early in the wireless communication process so as to maintain optimal network conditions.

A mobile radio communication network device is descried including a receiver configured to receive control information from a mobile terminal, wherein the receiver is configured to receive the control information in a first mode or in a second mode, wherein in the second mode, less of the control information is received in time from the mobile terminal than in the first mode, and a controller configured to control the receiver to receive the control information in the first mode if the mobile terminal is associated with a first mobile terminal mobility class and to control the receiver to receive the information in the second mode if the mobile terminal is associated with a second mobile terminal mobility class.

According to one embodiment, a communication device is described comprising a communication circuit configured to communicate in a first communication mode using a first frequency range and a receiver configured to receive a switching delay information message indicating a time interval by which start of communication in a second communication mode using a second frequency range should be delayed after a switch from the first communication mode to the second communication mode. The communication circuit is configured to communicate in the second communication mode when the time interval has elapsed since the start of the switching from the first communication mode to the second communication mode.

Methods and apparatus enabling a wireless network to optimize paging channel operation, based on mobile device context information. In one embodiment, the wireless network is a cellular network (e.g., LTE-Advanced), and both base stations and cellular user devices dynamically exchange and maintain a paging agreement. The paging agreement limits the paging channel operation, thereby minimizing unnecessary scanning and usage of irrelevant radio resources. Such paging mechanisms are limited to the air interface between the base station and the mobile device, and are compatible with existing legacy devices and network entities. Networks with appropriately enabled user devices may improve their resource utilization. Base stations may advantageously reclaim freed-up cellular resources to support other services.

A method is provided for handover of a communication of a mobile communication device between a first radio access network and a second radio access network. The method comprises storing, by at least one of the communication device and an element of the first radio access network, a context of the communication device in the first radio access network, the context being useable to transfer the communication back to the first radio access network after a transferring to the second radio access network; and transferring the communication to the second radio access network.
摘要:
Methods and apparatus for providing enhanced access options for wireless access points (e.g., cellular femtocells). These access options in one embodiment include various grades or levels of private and public access to available femtocell services. Each service may be separately assigned a various access type, such that a femtocell may service multiple users both within the “closed” group authorized by the femtocell white list, and non-members. In one variant, a femtocell broadcasts enhanced system information to all terminals (regardless of member/non-member status) such that a non-CSG (Closed Subscriber Group) member terminal or UE is capable of obtaining partial service access within the femtocell. Broadcast multimedia or other services can be delivered to both CSG members and non-members, advantageously without having to establish a dedicated connection for the non-member users.

In an embodiment, a radio communication device is provided. The radio communication device may include a radio communication device control message generation circuit configured to generate a radio communication device control message including allocation information to control a radio resource allocation for radio communication devices of at least two groups of radio communication devices, the radio resource allocation being provided by another radio communication device.
摘要:
A message generating arrangement determines whether a first communication terminal of a communication system can participate, by means of packet-switching network elements of the communication system, in a communication link in which a second communication terminal of the communication system is participating by means of circuit-switching network elements of the communication system, and generates a message on the basis of the result of the determination.
