  • Publication number: 20080037494
    Abstract: The invention provides a method, system, and user equipment for requesting a call in a communication system. When sending a request for setting-up a packet switched call to a first network, a timer is started for waiting for a response to the request. When detecting a change from the first network to a second network, a request for setting-up a packet switched call is sent to the second network in response to the detection of the network change without waiting for expiry of the timer. The call can thus be setup with the second network with reduced time delay.

  • Patent number: 7313111
    Abstract: A method for use by a WLAN terminal in determining which of at least some SSIDs on a preferred SSID list hosted by the WLAN terminal are available at one or another accessible WLAN access point, based on sending probe messages to accessible WLAN access points, each probe message indicating a respective SSID, but sending such a probe message for an SSID on the list only if a respective indicator included in the list indicates that the WLAN terminal is to probe for the SSID.

  • Publication number: 20070275710
    Abstract: A method for handling service failures for in a communications network comprising a user equipment, a first network element and a serving network element, the method comprising the following steps. Receiving at the first network element a first message from the user equipment. Transmitting the first message from the first network element to the serving network element. Detecting at the first network element that the serving network element is out of service. Determining at the first network element the type of the first message, and in dependence on the type of the first message sending from the first network element to the user equipment an error message including an indication that the serving network element is out of service.

  • Publication number: 20070165573
    Abstract: Due to possibly different standard versions implemented in a mobile station (MS) and a network, the MS may not be able to interpret all reject-cause values used by the network. In this case, a MS may receive upon a mobility-management (MM) request a reject message with an unknown reject-cause value and re-transmit its MM request. According to one aspect of the invention, a MM method for a mobile station in a public land mobile network, hereinafter network, is provided.

  • Publication number: 20050213566
    Abstract: The invention provides a method, system, terminal, and access network for selecting a service or service provider in a shared network configuration which includes at least one terminal, at least one access network, and at least two alternatively selectable services or service providers accessible via the access network. The access network broadcasts, to the terminal, a shared network domain, SND, code which indicates that at least two services or service providers are accessible via the access network. The broadcast SND code is changed only when there is a change in available services or service providers accessible via the access network. The terminal checks, only when SND code changes, available services or service providers by accessing a memory storing a list of SND codes and associated services or service providers. The terminal or the access network or another network element selects a service or service provider available in the shared network.

  • Patent number: 6658249
    Abstract: A method and an arrangement for setting data transfer parameters in a data transfer system is disclosed for use preferably in a digital cellular system. A data transfer connection may be established by setting first the parameters related to speech connection and then, during the speech connection, the data transfer parameters can be changed, when necessary to be suitable for data transfer. Then, at call setup, no data is needed on whether the data transfer connection is possibly to be used for data transfer.

  • Publication number: 20030114158
    Abstract: The invention relates to a method for performing an intersystem handover of a mobile terminal accessing a communication network via a radio access network of a first type. The communication network comprises at least this radio access network of this first type and a radio access network of a second type. In order to enable an access to the communication network with a radio access technology required or desired by the mobile terminal, the intersystem handover is initiated by a transmission of the mobile terminal to the communication network, which transmission comprises information indicating that an intersystem handover from the radio access network of the first type to the radio access network of said second type should be performed. The invention equally relates to a corresponding mobile terminal, to a corresponding communication network, to a corresponding communication system, to a network element of a communication network and to a web switch of a communication system.

  • Patent number: 6018653
    Abstract: The invention is related to a method and equipment used by a radio communication device (2) in a cellular network to determine whether a particular area specific service is applicable. A base station (6) transmits a first character sequence (4) which is advantageously a binary number. The radio communication device (2) selects on the basis of a second character sequence (5) stored in its memory (12) certain characters of the first character sequence (4) for examination. A logic AND or OR function (15-20) is performed for these characters indicating whether said service is applicable. By adding area specific character sequences (7) to the message sent by the base station (6) and making the recognition algorithms of the radio communication device more complex it is possible to establish a versatile service system with geographical and temporal variation. Said service can be, for example, area specific pricing.

  • Patent number: 5995825
    Abstract: In a radio telephone system including subscriber devices, such as mobile phones, that function in a network wherein a control channel is used to transfer call control messages between the network and a subscriber device, and a call consists of three consecutive phases involving a connection setup phase, an information transfer phase, and a connection termination phase, with the setup and termination phases including messages on the control channel, a call waiting service in which the network sends the subscriber device a control message announcing the arrival of a new call via the control channel, which service is valid in desired phases or parts of phases of the call.
