Abstract: A method and system for revenue sharing between mobile operators and content providers. The content providers, through a data network, provide data services to the end users of the mobile operators. For the data services, the content providers are paid by the mobile operators based on the revenue collected by the mobile operators from the end users using the services. An intermediate proxy is disposed between a mobile operator and the data network to keep track of the data amount transmitted by the content providers and the users and to keep track of the revenue sharing agreements established between that mobile operator and the content providers. Additionally, an intermediate proxy is linked to each content provider to keep track of the data amount transmitted to the end users via a mobile operator and to keep track of the revenue sharing agreement with that mobile operator.

Abstract: A method is disclosed for delivering a short message from an external short message entity (ESME) to a wireless device. The method comprises transmitting a message from a message source device such as an external short message entity to a gateway, the message being associated with a service type.

The rate input is adjusted over time according to a predetermined sequence so that the Doppler compensation signal compensates for the Doppler effect experienced by, for example, ground-to-satellite communications in a satellite communications system.

Abstract: A mobile unit, or UE (User Equipment) includes a Radio Resource Control (RRC) and a plurality of unique states defining the connectivity between the UE and a base station. Once a RRC indicates that it is “Out of Service”, a series of timers are started to limit the duration of attempts by the RRC to re-enter an “In Service” condition before the RRC releases allocated resources and moves to an Idle Mode. In certain circumstances, it is necessary to stop one or more of these timers to prevent inadvertently severing the connection.

Abstract: An improved echo control system has an adaptive controlled echo canceling filter arrangement in which a background filter updates the filter coefficients of an echo shaping filter responsive to a normalized least mean square (NLMS) algorithm. An adaptive control module determines a weighted reference signal for the background filter in which the weight is proportional to a far signal reference and an estimate of the norm of an echo canceller error vector, and inversely proportional to en estimate of a residue of the echo canceller. And a non-linear normalized convergence term is used in the NLMS algorithm.

Abstract: It is desirable to allow mobile stations such as mobile telephones or cell phones to connect to a wireless cellular network even without the presence of a SIM card or other identification information. This is desirable for example, for access to emergency services. By configuring the mobile station to be able to populate replies to request for identification information during call set up which are received from the network, it is possible to avoid redesigning the network while providing “SIM-less” access to the network.

Abstract: A method (400) for relocating a serving network entity is presented. Before the relocation certain packet data information is transmitted between a terminal and a first network entity (901) at least via a second network entity (902) and via a third network entity (903). The first network entity (901) is connected to the second network entity (902) with a first path (911) and to a third network entity (903) with a second path (912), and the second network entity, which is before the relocation acting as the serving network entity, is connected to the third network entity, which is its peer network entity and after relocation acting as the serving network entity, with a third path (913). The first, second and third paths are separate paths. After the relocation said information is transmitted via the third network entity.

Abstract: A telephone has a key pad with ten number keys arranged to dial the digits from 0 to 9 inclusive, each of these number keys being marked with a visual indicator denoting the digit which the number key is arranged to dial. The 1 and 9 number keys are provided with tactile indicators, distinguishable from one another by touch, so that a user can dial 911 by touch under conditions, such as in thick smoke or during a power failure, when the visual indicators on the keys are not readily distinguishable. The tactile indicators do not substantially obscure the visual indicators on the keys bearing the tactile indicators, and are not the Braille equivalents of these visual indicators. An existing telephone may be retrofitted with the tactile indicators by providing two auxiliary members which can be secured to the 1 and 9 number keys, preferably with adhesive.

Abstract: A method for replenishing a pre-paid telecommunications account utilizes the short message service (SMS). When an account balance is low, a pre-paid service control point (PP-SCP) sends a message to a pre-paid payment server which composes an SMS message and sends it to a short message service center (SMSC). The SMSC forwards the message to a mobile switching center (MSC) which passes the message to the subscriber's mobile unit. A confirmation message is automatically sent in a similar manner back to the pre-paid payment server. To replenish the account, the subscriber composes an SMS message using the mobile unit and sends the message to an MSC which forwards it to the pre-paid payment server via an SMSC. The pre-paid payment server validates the request via a billing and finance system, then sends a message to the PP-SCP for account update.
