An MS, for a GSM/EDGE network, arranged to, as a first alternative, use every 13th TDMA frame with an odd number as an idle frame which is used for neighboring cell measurements and every 13th TDMA frame with an even number as a PTCCH, a Packet Timing Control Channel. The MS is arranged to, as a second alternative, use every 13th TDMA frame with an odd number as a PTCCH and every 13th TDMA frame with an even number for neighboring cell measurements. The MS is arranged to transmit information to the network that the MS supports the use of the second alternative, and to receive information from the network about which of these two alternatives that the MS should use.

The present invention relates to methods and arrangements of handling inter-working between different radio access technologies in a telecommunication system comprising communication network nodes (10; 15) communicating with a plurality of user equipments (18) on uplink (17) and downlink (16) channels. Radio access technology priority settings depending on in which operation mode said user equipment (18) is in, sent by the communication network node (10; 15), are received in the user equipment (18).

Described is a method for managing locally switched call connections in a wireless communication network comprising receiving, at a core network node, a first message indicating that a first user equipment connected via the locally switched call connection has been detected in a target radio access node and transmitting, triggered by the first message, a second message requesting a status change of the locally switched call connection to a second user equipment, such that a user plane data path from the first user equipment to the second user equipment is switched to a core network path. Moreover, the method is implemented in a network node, while the method steps can be executed by means of a computer program product comprising instruction sets performing each method step.

A Mobile Station, an MS (700), for a GERAN system, the MS (700) being arranged (705, 710, 750, 730) to receive bursts from a Base Transceiver Station, a BTS, each of said bursts being modulated with a modulation type chosen from one of a number of modulation types. The MS is arranged (730, 740) to identify bursts from the BTS which may comprise information for the MS by identifying if a Training Sequence Code, a TSC, which is comprised in received bursts corresponds to a TSC which the MS has been assigned, the MS being arranged (705, 710, 750, 730, 740) to be assigned a first and a second TSC to be used for at least one of said modulation types.
摘要:
Embodiments herein include methods and arrangements for controlling access of mobile devices to a network, such as GSM. The mobile devices belong to an access control class (ACC) and also belong to an additional access control class (EACC) that provides extended access control. The arrangement broadcasts system information to the mobile devices that comprises a first indicator indicating an ACC. The first indicator indicates whether a mobile device is allowed to access or is barred from accessing the network. The system information further comprises a second indicator indicating an EACC. The second indicator indicates whether a mobile device is allowed to access or is limited from accessing the network. Limited access may entail blocking a mobile device from initiating communications with the network, blocking the mobile device from receiving network initiated communications, or both. A mobile device blocked from network initiated communication may not answer a page from the network.

A method of accessing a communications channel, the method comprising: assigning a time transmission interval (TTI) and at least one temporary block flow (TBF) during an Access Grant Channel (AGCH) assignment; allocating an additional field in an Immediate Assignment message sent on the AGCH; using the additional field to simultaneously assign to a mobile station (MS) at least one temporary block flow on an uplink of the communications channel and at least one temporary block flow on a downlink of the communications channel.

The present disclosure relates to a method and a transmitting unit for reducing a risk of transmission stalling between a transmitting unit and a receiving unit in a communication network system comprising said transmitting unit arranged to transmit data blocks to said receiving unit. Each data block comprises a block sequence number and transmitted data blocks are stored in a transmission buffer. A transmission buffer window is arranged to control the flow of retransmission of said transmitted data blocks. When the block sequence number has been acknowledged in a piggybacked acknowledgement/negative acknowledgement field, it is only set as acknowledged upon receipt of a packet uplink acknowledgement/negative acknowledgement message or a packet downlink acknowledgement/negative acknowledgement message comprising an acknowledgement for said block sequence number.

A method in a Gateway General packet radio service Support Node, GGSN, for transferring a service identifier from a packet core network to a radio network is provided. The GGSN adds a service identifier in a General packet radio service Tunneling Protocol for User Plane, GTP-U, header extension of a data packet. The service identifier comprises information about what service and/or traffic pattern that the packet concerns. The GGSN sends the data packet with the GTP-U header extension to a radio network.

A method of performing congestion notification for a data transmission (10) from a sender (14) to a receiver (11) is described. Furthermore, nodes for such a transmission as well as methods of controlling such nodes are described. The data transmission involves a first node (12) and a second node (13) between said sender and receiver. The data packets pass from said second node to said first node towards said receiver. The method comprises: —sending (S82) a message (15) from said first node to said second node, said message relating to a decision on whether to notify said receiver of a congestion condition in said data transmission, —sending (S83) an explicit congestion notification (16) from said second node to said receiver if it is decided to notify said receiver of said congestion condition.
摘要:
A base station subsystem (BSS) and a method are described herein for improving an Access Grant Channel (AGCH) capacity when mobile stations establish an uplink Temporary Block Flow (TBF) triggered by a small data transmission (SDT) or an instant message transmission (IMT). Plus, a mobile station (MS) and a method are described herein for improving the AGCH capacity when the mobile station establishes an uplink TBF triggered by a SDT or an IMT.
