A method in a user equipment for handling cell selection is provided. While in dedicated mode the user equipment receives from a radio network node a measurement information message which indicates at least two frequencies associated with a respective cell in a respective radio access technology. While it is in dedicated mode, the user equipment performs measurements on the frequencies to obtain a respective measurement value for each one of them, and receives a selection indicator message comprising a respective priority for each one of the frequencies. The user equipment obtains a respective threshold value for each of the frequencies and successively evaluates the frequencies in descending priority order until a frequency is determined for which the measurement value exceeds its respective threshold value. When entering idle mode, the user equipment selects cell based on the evaluation.

In a method in a central node of a cellular radio network the central node is adapted to deciding if a mobile station connected to the cellular radio network via a first radio access technology controlled by the central node is to be moved to another radio access technology when a circuit switched call of the mobile station is ended. It is assumed that the cellular radio network is adapted to use a fallback to circuit switched procedure. First it is decided that a CS call for a particular mobile station has ended. Then in it is checked if the CS call was the result of a fallback to CS procedure. The central node then decides if the mobile station is to be moved to another radio access technology based at least partly on the, i.e. if the CS call was a result of a CS fallback procedure.

The present invention relates to methods and arrangements of handling inter-working between different radio access technologies in a telecommunication system comprising communication network nodes (10; 15) communicating with a plurality of user equipments (18) on uplink (17) and downlink (16) channels. Radio access technology priority settings depending on in which operation mode said user equipment (18) is in, sent by the communication network node (10; 15), are received in the user equipment (18).

The invention relates to a method for setting up a connection between an originating mobile entity and a terminating mobile entity connecting to the same radio access network of a mobile communications network, the radio access network accessing a core network through a serving access gateway serving one of the two mobile entities the method performed by the serving access gateway comprising the steps of receiving a connection setup message for establishing the connection between the originating and the terminating mobile entity, wherein the connection setup message transmitted along a signalling path in the core network comprises an information element storing media plane access needs of at least one network node in the signalling path of the core network, wherein the media plane access needs indicate the needs of a network node in the signal path of the core network to access a media plane of the connection to be set up. Additionally it is checked whether any of the network nodes in the signalling path of the core network needs access to the media plane of said connection to be set up, wherein, if none of the network nodes needs access to the media plane and if the serving access gateway needs access to the media plane at least the following steps are carried out: a media gateway that is handling a media stream of the serving access gateway is instructed to provide an uplink endpoint for the connection to the originating mobile entity and an uplink endpoint for the connection to the terminating mobile entity for the connection to be set up, and the radio access network is informed to transmit the media stream of the originating and the terminating mobile entity to the media gateway of the serving access gateway needing access to the media plane.
摘要:
A network entity for a radio communication network includes a processing unit which causes a first resource and a second resource for a terrestrial interface of the radio network to be seized, where the first resource is distinct and different from the second resource. The entity includes a network interface through which a handover request or an assignment request message identifying the first and the second resource is sent. A network entity for a radio communication network includes a network interface which receives a handover request message or an assignment request message identifying a first resource and a second resource. The first resource is distinct and different from the second resource. The entity includes a processing unit that selects one of the first and second resources, allocates a radio channel associated with the handover or assignment, selects a bearer for a terrestrial interface and seizes resources for the interface.

A Mobile Station, MS (115), for a cellular communications network (100), arranged to be camped on one of a plurality of k available Common Control Channels, CCCHs, in a cell (105) in the cellular communications network (100), the MS (115) also being arranged to make successive attempts at uplink CCCH access until the MS (115) gains CCCH access. The MS (115) is arranged to make CCCH access attempt number i on CCCH number x, where x is in the range of 1 . . . k, with x determined by a function in the MS (115). Also, a network node, (110), for a cellular communications network, arranged to transmit System Information messages, to the MSs (115) in a cell, and arranged to insert an Information Element, an IE, in an SI message, which IE defines which CCCHs in the cell that an MS (115) may use for uplink CCCH access attempts.
摘要:
A first node (110, 115, 135, 200) for an IP connection with a second node over an A interface between a Access Network (101) and a Circuit Switched Core Network (122), said IP connection comprising an RTP and an RTCP connection. The first node has an RTP address comprising an IP address and a UDP port in the RTP connection and can change its RTP address and signal said change by a message to the second node (200, 135, 110, 115) over the RTCP connection and receive an ACK message. The first node is arranged to, following said change of RTP address, receive user plane data over the RTP connection from the second node at its changed and unchanged RTP address and to initiate an Internal handover with Mobile Switching Centre support if said ACK message from the second node is not received within a time limit.
