Abstract:
A system, method, and apparatus in an access network such as the Generic Access Network, GAN, for providing user-type information to a Security Gateway, SEGW, (10) or for enabling the SEGW to obtain user-type information for different user types so that the SEGW can apply specific security functions based on the user type. The invention may also provide user-type information to a controller node such as a GAN Controller, GANC, (13) or may enable the GANC to obtain user-type information for application of security settings toward GAN-clients. An Authentication, Authorization and Accounting, AAA, Server (25) may create a user-type indication internally, or may obtain an indication from a Home Location Register (26) and forward the indication to the SEGW. The SEGW may forward the indication to the GANC, or the GANC may determine the user-type information internally or retrieve it from a database.
Abstract:
A method and arrangement are proposed for facilitating handover from a 3 G WCDMA UTRAN to a generic access network (GAN) cell. In preparation for handover, mobile stations measure the signal level transmitted from neighbouring cells as instructed by the RNC. When in a WCDMA UTRAN, the measurement of inter-frequency cells, i.e. cells having a frequency number that is different from the serving cell, requires the network to generate time gaps during which the mobile station can perform measurements on different frequencies (compressed mode). GAN cells do not transmit on their allotted frequency number, but this number together with an identifier is used to identify the GAN cell between the MS and RNC. In order to permit GAN cells to always have the same frequency number as neighbouring UTRAN cells, a modified registration procedure is proposed, wherein the MS communicates the frequency number used in the current UTRAN cell to the GAN controller, which adopts this frequency, and if necessary uses it to determine the corresponding identifier. The identifier may be the same for all GAN cells, or can be obtained from a small mapping table, which maps an identifier to each frequency or to a group of frequencies.
Abstract:
The present invention describes a method for estimating a position of an Access Point in a wireless communications network. The Access Point, used for connecting wireless networks to a core network, is being equipped with a User Equipment module, UE module. The UE module is used for scanning, for example upon a triggering event, a surrounding environment of the Access Point to identify neighbour Radio Base Stations . The Access Point then creates a neighbour list including information relating to neighbour Radio Base Stations. The Access Point forwards the neighbour list to the Network Control Node, wherein the Network Control Node uses the information in the neighbour list to estimate a position of the Access Point.
Abstract:
The present invention relates to a method in a telecommunication system to indicate tariff related information to an end user (MS; MSA; MSB) with ability to access network areas with different charging tariffs. The system comprises a Core Network (CN) associated with an Access Network (RAN; GAN; AN) handling different cell areas (MACRO-C, FEMTO-Cl; MCELL, FCELL-A). The method comprises the following steps: Accessing the Access Network (RAN; GAN; AN) by the end user (MS; MSA; MSB) via a radio base station handling a cell area (FEMTO-Cl; FCELL-A) in which the end user is located. Selecting a charging indication (SAI, CGI, CNII) in dependence of access information identified during the access. Selecting in the Core Network, in dependence of the selected charging indication (SAI, CGI, CNII), tariff related information to be sent to the end user.
Abstract:
A method of controlling access to services of an IP Multimedia Subsystem by a user based upon the user's location. The method comprises, in response to a user requesting access to a service of the IP Multimedia Subsystem, providing information identifying the user's location to the IP Multimedia Subsystem. Within the IP Multimedia Subsystem, the provided identification information is compared with authorisation information stored on a database, the authorisation information comprising information identifying prohibited and/or allowed access locations. Dependant upon the result of the comparison, access to the IP Multimedia Subsystem services is allowed or denied.
Abstract:
In cellular mobile networks handover between base stations of adjacent cells requires the identity, address and frequency of all adjacent cells to be known to other elements of the network. Conventional networks (e.g.cellular networks) can be extended by the addition of unlicensed-radio access networks. Said unlicensed networks can include an access network controller (303) preferably connected via a broadband network (302) to a plurality of low-power local base stations (301), which communicate with mobile stations (1) over an unlicensed radio interface. The number and changing location of the local base station renders the operation and maintenance required to enable handover from the conventional network to these access networks prohibitively complex. This difficulty is alleviated by assigning to all the mini-cells of the unlicensed network a single identifier being said single identifier associated to the access network controller. With this arrangement regardless of which base station mini-cell (304) an active call is being handed-over to, the conventional network will be able to route the request to the access network controller.
Abstract:
A method of controlling the allocation of transmission resources to wireless terminals within a radio access network, which resources are required for the provision of an IP Multimedia service to the terminals. The method comprises, in the event of a requirement to change the allocation of transmission resources to a given wireless terminal, sending a resource allocation request from a control node of the IP Multimedia Subsystem to the radio access network, the request causing a resource control node of the radio access network to change the allocation of access network resources to the wireless terminal.
Abstract:
A system and method for adapting circuit-switched payload transport between a mobile station, MS, (30) and an unlicensed-radio access network utilizing the Real-Time Transport Protocol, RTP. The MS (30) and an access network controller (103) negotiate the number of speech/data frames per RTP packet during the assignment of a traffic channel. The network controller notifies (62) the MS of a requested or minimum acceptable sample size, and the MS utilizes that sample size, if able, to send (86) RTP packets to the network controller. If the MS is not capable of utilizing that sample size, the MS utilizes the closest sample size that the MS can support to send (89) packets to the network controller. The network controller then calculates (90) the sample size utilized by the MS and utilizes (91) the calculated sample size in transmissions to the MS. Thereafter, if network conditions change, another negotiation is initiated (94-97) to adapt the sample size to the changed conditions.
Abstract:
The present invention provides a method and architecture on how mobile stations (MS 132) are provisioned about information of an unlicensed mobile access (UMA) network controller (UNC 142). The UNC (142) in accordance with the present invention provides three different logical roles (i.e., provisioning (300), default (302) and serving (304)). More specifically, the present invention provides a method for assigning a mobile station (MS 132) to an unlicensed mobile access (UMA) network controller (UNC 142) in an unlicensed mobile access network (UMAN 102). The MS (132) is connected to a provisioning UNC (402) and discovers a default UNC (404). A serving UNC (406) is then determined to assign the MS (132) to and the MS (132) is assigned to the serving UNC (408). The serving UNC (620) can be the default UNC (612), the provisioning UNC (604) or another UNC.
