Abstract

An interworking function in a core network system, such as a 5G core network, attempts to establish a secure association with user equipment (UE) in an untrusted access network. When the secure association is not accepted by the 5G core network, the UE receives from the core network a response including a message type indicating that Non-3GPP access to the 5G core network is not allowed. Upon receiving the response message, the UE ends the session by sending a 5G- Stop message formatted in an Extensible Authentication Protocol (EAP) response. The EAP-Response/5G-Stop message includes a message-id field with a 5G Stop value.

Abstract

There is proposed a charging control in which a policy and charging control function provides first (preliminary) charging control information, such as PCC rules, when the communication connection is set up or modified. Then, service infor-mation can be retrieved leading to an updated set of charging control information. The policy and charging control function pro-vides then the updated charging control information for enforcement, wherein the charging system is informed about both the pre-liminary nature of the first charging control information and the validity of the second charging control information for a time be-fore the update, i.e. before the transmission of the second charging control information. The charging system can use this updated charging control information and knows that it has to replace the former charging control information, so that the charging proce-dure can be corrected accordingly. Thus, charging of a service running on the communication connection on the basis of correct charging control information is possible over the complete time the service is running.

Abstract

A user equipment (UE) receives a first dynamic resource allocation on a first channel (PDCCH), then sends data according to the first resource allocation. During a time at which an ACK/NACKforthe sent data is scheduled to occur on a second channel (PHICH), the UE is engaging in an activity that takes priority over the ACK/NACK. The UE then receives a second dynamic resource allocation on the first channel and determines the ACK/NACK for the sent data from the second dynamic resource allocation. The determining can be direct, as in receiving a zero-valued resource allocation; or it may be indirect as in mapping the second dynamic resource allocation to the second channel and receiving the acknowledgement on the second channel afterthat mapping. Also detailed are similar mirror actions from the Node B's perspective, as well as apparatus, methods, and embodied computer programs.

The transmitting device is capable of receiving at least two different types of positive/negative acknowledgements for data blocks of said type from said receiving device and the reaction of the transmitting device to the positive/negative acknowledgements depends on the type of the said received positive/negative acknowledgement.

Abstract

This invention is related to a system and method to setup a radio link in a CDMA mobile communication network. In particular, a radio network controller (RNC) sends a radio link setup request message, and a processing device receives the radio link setup request message. The processing device sends a radio link setup response message to the RNC, and the response is received the RNC and includes frame and chip offset information. In particular, frame and chip offset in a RNSAP Radio Link Setup Response message (after execution of UE involved relocation) is conveyed. A new SRNC will then include a random frame offset in the RNSAP Radio Link Setup Request message. The eHSPA Node B will ignore the random fame offset, and include the correct frame offset in the RNSAP Radio Link Setup Response message.

Abstract

A set of specific sequences comprising a set of root sequences and cyclic shifts thereof is searched, wherein it is started from a root sequence index indicating a root sequence of ordered root sequences, available cyclic shifts of the root sequence are included, and it is continued with a next root sequence if necessary for filling the set, interpreting the ordered root sequences in a cyclic manner.

Abstract

Block spreading generating partial orthogality is applied for the uplink control channel for E-UTRA. For instance, a problem of maximizing the multiplexing capacity leads to numerology causing odd-length sequences which do not have the favorable property of even-length sequences (partial orthogonality). The consequence of this is poor performance in cases of high Doppler effects. Maximal multiplexing capacity is taught without loss of performance at high Doppler by modifying an earlier scheduling request (SR) scheme. The earlier SR multiplexing scheme has a number of parallel SR resources per slot equal to 12*7=84. In one example, the spreading factor of block spreading is changed to an even number, e.g., from 7 to 6. This enables usage of the partial orthogonality properties of CAZAC sequences and as a result inter-code interference in the case of high Doppler is reduced. Other ways to generate partial orthogonality are shown with similar results.

Abstract

A method, comprising: receiving a re-quest for retransmission from user equipment for a pre-determined transmission time interval in a communication network; determining whether a collision risk exists between the retransmission and another transmission during the predetermined time interval; and ignoring the retransmission request when the determined collision risk exists.

Abstract

The specification and drawings present a new method, system, apparatus and software product for determining (e.g., calculating) a load measure by a network element (e.g., Node B or any other network element) for optimizing information traffic in communication networks (e.g., wireless communication systems). This load measure can represent the amount of available/excess traffic that a given network element can carry and is a relative measure, which would take into account the total amount of resources available in the system and the amount of resources that are free for carrying only "important" or "essential" traffic, using a weighed method described herein.

Abstract

A cyclic shift of a reference signal is quantized as a combination of a cell specific cyclic shift with an outcome of a pseudo-random hopping, and an indication of the cell specific cyclic shift is broadcast in the cell. In one embodiment the cyclic shift is quantized as a modulo operation on a sum of the cell specific cyclic shift, the outcome of the pseudo-random hopping, and a user specific cyclic shift, in which case an indication of the user specific cyclic shift is sent in an uplink resource allocation and a user sends its cyclically shifted reference signal in the uplink resource allocated by the uplink resource allocation. The cyclic shift may also be quantized according to length of the reference signal as cyclic_shift_symbol= (cyclic_shift_value * length of the reference signal)/12; where cyclic_shift_value is between zero and eleven and cyclic_shift_symbol is the amount of cyclic shift given in reference signal symbols.

Abstract

There are disclosed measures for policy control in a network, including an authorization check. Namely, a method of policy control in a network comprises obtaining, at an application function entity of the network, a request for a service, determining, at the application function entity, whether service information associated with the requested service requires an authorization check or a configuration of a policy enforcement entity of the network, and providing, depending on the determining result, an indication from the application function entity to a policy control entity of the network, whether or not the policy enforcement entity is to be configured for the requested service information, together with that requested service information.
