摘要:
The present invention relates to methods and arrangements to test end to end relations between gateways MGW1, MGW2 in an IP network IPNW, which method comprises the following steps: 1) reserving call handling resources CH231-CH260 in a destination gateway MGW2; 2) sending data packets RTP/UDP/IP from an originating gateway MGW1 to the reserved call handling resources CH231-CH260; 3) looping back the received data packets RTP/UDP/IP, from the destination gateway MGW2 to the originating gateway MGW1; 4) providing quality statistics for the received data packets, in the originating gateway MGW1.

A system and method for routing an incoming telephone call to a mobile terminal (106) which is a combined cordless phone and mobile phone. The call will be connected over either a fixed network (104) or a mobile network (102) depending on whether the mobile terminal is within or out of radio coverage of a home base station (110) connected to the fixed network. The call is routed in response to a routing indication which is included in the called number of the mobile terminal depending on the location of the mobile terminal. In this way, network operators may direct calls over the fixed network in preference to the mobile network, thereby relieving the mobile network. A single telephone number can also be used for the combined cordless phone and mobile phone.

The combination of narrowband applications with broadband transport may be enabled with a tri-level nodal system in which a narrowband node (e.g., a telecommunications node) may provide switching intelligence to the switching fabric of multiple broadband nodes (e.g., media gateways). The switching intelligence is provided via an intermediate node (e.g., mediation logic) that emulates a switch interface for the narrowband node and translates circuit-based addresses/routing instructions to packet-based addresses/routing instructions. This translation equates to a mapping of address(es) in a first address space to address(es) in a second address space in order to utilize the address(es) of the second address space for propagating communications on a broadband transport mechanism.

A method and a mobile services switching center of providing differentiated services in a communications network. The method comprises receiving in a mobile services switching center an indication message from a first radio access network, said message indicating a radio access network type to which a called communication apparatus of a terminating communication session is connected, in response to the indication message: accessing differentiated service information associated with the radio access network type of the terminating communication session, and sending the differentiated service information to be applied for service differentiation by a second access network of calling communication apparatus.

The invention relates to a method of establishing a session between client user terminals accessing IP Multimedia Subsystem, IMS, networks. At least one of the IMS networks implements the use of Quality of Service, QoS, preconditions, and at least one of the client user terminals does not use QoS preconditions. The method includes receiving, at an inter-working function, IWF located in one of the IMS networks, an IMS session initiation request originated by an originating client, the request indicating a terminating client for the session. A decision is made, based on the session initiation request, that one of the originating client and the terminating client is not using QoS preconditions. A set of QoS preconditions is inserted into a procedure for establishing the IMS session on behalf of the client that is not using QoS preconditions. Session establishment is completed only after QoS resources complying with the set of QoS preconditions have been established.

The invention provides a method of enabling the service level networks (e.g. CSoLTE or IMS CN) to provide location-dependent services based on a circuit switched domain from a service level network to a mobile station communicating with a cell in a radio access network that utilises a packet switched domain. The method includes providing cell location information relating to the location of the cell; determining a Service Area Identifier based on the cell location information; and providing the Service Area Identifier to the service level network. The Service Area Identifier is then used for different location based services and applications in the service level network nodes.
摘要:
A method, server, and terminal for selecting an access domain for sending information between a wireless terminal and a core network, wherein sessions between the wireless terminal and the core network are established and controlled using an IP Multimedia Subsystem (IMS). A database maintained in the IMS stores information regarding real-time packet-switched service capabilities of a plurality of access domains. The database is interrogated based upon currently used and/or available access domains. An access domain is selected for use by the wireless terminal based upon the results of the interrogation.

摘要:
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 can be extended by the addition of unlicensed-radio access networks. These 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 the whole access network a single identifier. 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.
摘要:
The present invention provides a method and architecture on how mobile stations (MS) are provisioned about information of an unlicensed mobile access (UMA) network controller (UNC). The UNC in accordance with the present invention provides three different logical roles (i.e., provisioning, default and serving). More specifically, the present invention provides a method for assigning a mobile station (MS) to an unlicensed mobile access (UMA) network controller (UNC) in an unlicensed mobile access network (UMAN). The MS is connected to a provisioning UNC and discovers a default UNC. A serving UNC is then determined to assign the MS to and the MS is assigned to the serving UNC. The serving UNC can be the default UNC, the provisioning UNC or another UNC.
