A method for performing a detach of a terminal registered to a telecommunication network is disclosed. The detach is performed by associating an identification for the terminal, deriving a signature for the identification, and allocating a pair consisting of the identification and the signature to the terminal. The method further includes sending the detach request including the identification and the identification signature from the registered terminal to the network. The detach request is received at the network and compared to a record of registration data of the terminal kept at the network. The terminal is detached from the network if the received detach request coincides with the record of registration data.

Method for a secure detach procedure in a radio telecommunication network

The invention is a system and method of controlling an access of a subscriber to a network. The method includes sending an identification of the subscriber and a level of access to be provided to the subscriber from a visited network of a plurality of networks () connected to a home network (); in response to the identification of the subscriber and a level of access to be provided to the subscriber, storing a subscriber profile of the authorized of access to be provided to the subscriber; and controlling access of the subscriber to any network dependent upon a comparison of access to be provided to the subscriber and the stored subscriber profile.

System and method of controlling application level access of subscriber to a network

The present invention proposes a method for performing a detach of a terminal registered to a telecommunication network by associating an identification for said terminal, deriving a signature for said identification, and allocating a pair consisting of said identification and said signature to said terminal, said method comprising the steps of: sending a detach request including said identification and said identification signature from said registered terminal to said network; receiving said detach request at the network side; comparing said received detach request with a record of registration data of said terminal kept at the network side; and detaching said terminal from said network, if said received detach request coincides with said record of registration data.

Method for a secure detach procedure in a radio telecommunications network

The present invention relates to providing methods and apparatus for identifying a location area of a mobile device, determining whether an LBS application should be activated on the mobile device based on the location area and activating the LBS application on the mobile device. A Mobile Network Operator server may identify the location area of a mobile device and activate an application on the mobile device while a third party LBS application provider server may make the determination as to whether an LBS application should be activated on the mobile device.

Activating location based service applications

This invention relates to security procedures in a communication system, specifically to production of key material. The invention provides a method for producing key material in a highly secure way for use in communication with a local network of a company. The method uses authentication information obtained from the communication system and information exchanged locally between a mobile station and the authentication systems of the company to produce a communication key for use in authentication procedures or e.g. for signing and/or encrypting data.

Method for producing key material for use in communication with network

In a GPRS system, a method of a mobile station acquiring an IP network address. The method comprises the steps of: the mobile station generating a link identifier and sending it to a gateway over a wireless link in a network address request together with a request to check if the link identifier is unique; the gateway receiving the network address request and checking if the link identifier is unique; the gateway responding with a network address request response including either the sending a unique link identifier confirmed as being unique or a different unique link identifier; the gateway sending a network prefix to the mobile station; the mobile station combining the interface identifier and the network prefix to generate the IP network address.

Address acquisition

The present invention relates to a method and system for changing a subscription information of a subscriber in a data network. When a subscriber profile or subscription information is changed or updated, this is detected and a registration procedure for registering a terminal device () of the subscriber to a new serving network element () is initiated in response to the result of a checking step for checking whether a capability of a network element () serving a terminal device () of said subscriber is still in accordance with said changed subscription information. Thereby, an automatic or semi-automatic adaptation of the serving entity to the changed subscription can be achieved.

Method and system for changing a subscription

Disclosed are devices, systems and methods including a wireless terminal adapted to perform a detach of the wireless terminal when registered to a telecommunication network by associating an identification for the wireless terminal, deriving a signature for the identification, and allocating a pair containing the identification and the signature to the wireless terminal. The wireless terminal includes a transceiver adapted to send a detach request including the identification and the identification signature from the wireless terminal to the network in response to detection of a predetermined state of the wireless terminal. The predetermined state includes one or more of, for example, a power off state, a low battery state, and/or a removal of a subscriber identity module from the wireless terminal.

The invention is directed to a communication network wherein a direct tunnel may be formed between a user equipment and a gateway support node, bypassing an intermediate serving support node. If, however, the gateway node should be outside of the actual communication network to which the user equipment is connected, a two-tunnel concept is used wherein a tunnel is provided between the user equipment and the serving support node. Likewise, when receiving a request for Lawful Interception, the tunnel formed between the user equipment and the gateway node is reconfigured to be directed to the serving node for guiding all user traffic and control signaling via this serving node.

Method and device for attaching a user equipment to a telecommunication network

An emergency telephone call is supported and routed to a Public Safety Answering Point (PSAP) in an IP based packet switched wireless communications network. An activate PDP context request is sent from a user equipment to the network. A parameter in said activate PDP context request indicates that the PDP context will be used to transfer an emergency call. An activate PDP context accept message is returned from said support node to said user equipment. Said activate PDP context accept message acknowledges said activate PDP context request message and provides the address of a call state control function. A call setup request transferred to the call state control function includes the Service Area Identity (SAI). The call state control function selects a PSAP based, at least in part, on the SAI included in the call setup request and forwards the emergency call to the selected PSAP.

Telephony services in mobile IP networks

Discloses are systems, methods, devices, including a method for performing a detach of a terminal registered to a telecommunication network by associating an identification for the terminal, deriving a signature for the identification, and allocating a pair containing the identification and the signature to the terminal. The method includes sending a detach request including the identification and the identification signature from the registered terminal to the network, receiving the detach request at the network side, comparing the received detach request with a record of registration data of the terminal kept at the network side, and detaching the terminal from the network if the received detach request coincides with the record of registration data.

A method and arrangement for determining the expiry time for a period during which the re-establishment of lost radio bearers is allowable. There is determined a first expiry time () for a period during which the re-establishment of lost radio bearers used to provide services of a first category, like real time services, is allowable. Additionally there is determined a second expiry time () for a period during which the re-establishment of lost radio bearers used to provide services of a second category, like non-real time services, is allowable.
