Abstract: Parameters of radio propagation between a mobile terminal and at least one fixed transceiver are measured. Report messages indicating at least a part of the measured parameters, in accordance with a mode of reporting specified by the radio network controller are transmitted to the radio network controller. An estimate of speed of movement of the mobile terminal is obtained at the radio network controller. The report messages are processed at the radio network controller so as to determine, by taking account of the said estimate of speed, a mode of reporting to be specified for a part at least of the report messages.

Abstract: The method seeks detection of a signal burst transmitted on the initiative of a sender on a radio channel listened to by a receiver system. The burst transmitted represents a predetermined digital sequence. Channel parameters representing a statistical behaviour of the radio channel are estimated and a detection magnitude is evaluated on the basis of the estimated channel parameters and of a correlation between a signal received at the receiver system and the predetermined digital sequence. The detection magnitude is compared with an adaptive detection threshold to decide whether the signal burst is detected.

Abstract: The present invention provides a session filter associated with an element to be protected in a communication network. Session requests intended for the protected element are processed by the session filter prior to being forwarded to the protected element. The protected element or a device associated therewith will provide event information indicative of undesirable session conditions, such as an overload condition, which necessitates a reduction or stoppage of incoming session requests for the protected element. The session filter will directly or indirectly receive the event information and take steps to reduce or stop the session requests being sent to the protected element. The session filter may filter the incoming session requests for the protected element and selectively send select session requests to the protected element, as well as send system protection responses to minimize the number of new session requests to devices generating or forwarding the incoming session requests.

Abstract translation: 本发明提供一种与在通信网络中要保护的元件相关联的会话过滤器。 在受保护的元素被转发之前，由会话过滤器处理针对受保护元素的会话请求。 受保护元件或与其相关联的设备将提供指示不期望的会话条件（例如过载条件）的事件信息，这需要减少或停止对受保护元件的传入会话请求。 会话过滤器将直接或间接接收事件信息，并采取措施减少或停止发送到受保护元素的会话请求。 会话过滤器可以对受保护元素的传入会话请求进行过滤，并且选择性地向受保护元素发送选择会话请求，以及发送系统保护响应以最小化向生成或转发传入会话请求的设备的新会话请求的数量。

Abstract: One controls the number of iterations of a process of iterative decoding of a symbol sequence coded according to a coding scheme using concatenation of convolutional codes in cases of non-convergence. One firstly calculates a quantity related to the convergence of the iterative decoding process, then one compares this quantity with a non-convergence threshold. As a function of this comparison, the iterative decoding process is halted while declaring the sequence undecoded.

Abstract: An apparatus and method of maintaining state information for a network device changing from a first channel (in communication with a first base unit) to a second channel (in communication with a second base unit) communicates with at least one of the first base unit and an intermediate network device to ascertain the state information. Once the state information is ascertained, it is applied to the communication of the network device with the second base unit. Both the first and second base units are independently operable network devices in a data transmission network.

Abstract: In a mesh connected communications network, nested link protection for a working link between two nodes across the network is provided. In the event of a fault on the working link between the two nodes, traffic on the link may be switched to a single parallel link between the two nodes, thereby restoring traffic on the link. Additionally, a link protection path extending between the two nodes is provisioned by way of at least one intermediate node. In the event the parallel protection link is not available, traffic carried on the working link may be switched to the link protection path, restoring traffic to the second node by way of the intermediate node. Conveniently, link protection path switching may be used in the event the parallel protection link is not available or at the choice of an operator.

Abstract: The present invention divides the available sub-carriers in an OFDM symbol window into N groups of sub-carriers wherein each group will be associated with sub-bands. In one embodiment, the sub-carriers in a group are spread throughout the range of sub-carriers to improve frequency diversity, and the sub-carriers assigned to any one group are separated by a constant offset. The sub-carriers in the group may be offset by an integer power of two. Within each group, sub-bands are defined using frequency hopping patterns among sub-carriers in the group from one OFDM symbol window to another. A pseudo-random pattern may be employed for sub-carrier mapping from one OFDM symbol window to the next to effectively distribute the sub-bands across the selected band of sub-carriers for the group.

Abstract: The present invention provides for the discovery of an Internet Protocol (IP) address of an application server associated with an IP network. An IP device is granted access to an IP network. Access to the IP network assumes an IP address assignment for the IP device. The network domain name is discovery by performing a Reverse DNS query on the assigned IP address or an IP address associated with the IP network device granting access to the IP device. Using a application server domain name (derived from the network domain name) a DNS query is perform to determine all IP addresses associated with the application server domain name.
