摘要:
The invention provides an increase in the radio coverage area (10) of a base transceiver station (100) having access to multiple transceivers (102, 104, 106, 108) by dedicating at least one of the transceivers (102) for BCCH data. This BCCH transceiver (102) is connected to an antenna arrangement (120) 5 comprising at least two antenna elements (121, 123; 125, 127). Increased BCCH radio coverage (30) is achieved by providing antenna hopping among the at least two antenna elements (121, 123; 125, 127) for the BCCH. Correspondingly, increased TCH coverage (20) is achieved by providing frequency hopping among at least two carrier frequencies for the TCH. The 10 coverage (10) of the base transceiver station (100) is defined as the intersection of the BCCH radio coverage (30) and the TCH coverage (20).

摘要:
A method and system for forwarding information to a device in a communication network are disclosed. According to one aspect, a method includes selecting a serving node to which to send a request. The selected serving node is one of plurality of serving nodes, each of the plurality of serving nodes supporting a different access technology. The request is to transmit one of a short messaging service, SMS, message and trigger information. The request includes a list of the plurality of nodes. The method further includes sending the request to the selected serving node via a translation interface associated with the selected serving node. The translation interface is adapted to use a protocol that corresponds to the access technology of the selected serving node. If the selected serving node cannot reach the device, the request is forwarded to another serving node in the list of serving nodes in the request.

A method for improving session continuity for a terminal (204′) in a serving communication network (202′) distinct from a home communication network (200′) of the terminal (204′), wherein the serving communication network (202′) comprises a session transfer node (208′) for transferring sessions each comprising signaling data and media data from a first access network (210′) of the serving communication network (202′) to a second access network (212′) of the serving communication network (202′) comprises the following: Routing signaling data of a session of the terminal (204′) between the first access network (210′) and the home communication network (200′) via the session transfer node (208′) in the serving communication network (202′), receiving a session transfer request requesting the transfer of the session from the first access network (210′) to the second access network (212′) for the terminal (204′), and transferring the session from the first access network (210′) to the second access network (212′), and routing the signaling data of the session of the terminal (204′) between the second access network (210′) and the home communication network (200′) via the session transfer node (208′).
摘要:
A node for use in a cellular system, arranged to establish a context for a User Equipment, UE, for the message types of Short Message Service, SMS, Small Data and Trigger Information. The node is arranged to establish the context when the UE performs an Initial Attach to the cellular system and indicates support for at least one said message types. The node is arranged to have two modes available for the context, those modes being a Currently Serving mode and a Forwarding mode, when in the Currently Serving mode, messages are delivered to the UE, and, when in the Forwarding mode, messages are forwarded to a node that is in the Currently Serving mode at the moment.
摘要:
A wireless terminal (30) is capable of communicating with a first network (22-1) and a second network (22-1, 22-3), the first network (22-1) being an LTE network. A wireless terminal method comprises (prior to making a request to participate in a circuit switched call with the second network) the wireless terminal (30) camping on a respective selected cell (of each of the first network and the second network and thereby having tuned to both the selected cell for the first network and the selected cell for the second network. In view of already camping on the selected cell of the second network, the wireless terminal (30) does not make a measurement with respect to a cell of the second network in a time period between the making of the request to participate in the circuit switch call and actual establishment of the circuit switched call with the second network.

A method of registering a subscriber in an IP Multimedia Subsystem (IMS) is provided, wherein the method is executed by a call control node (800), wherein the method comprises receiving (402) an access request of the subscriber for circuit switched accessing the IMS, the access request being received via an access, determining (404) an access type of the access, and sending (406) a registration request for circuit switched registering the subscriber in the IMS depending on the determined access type.
摘要:
The embodiments herein relate to a method in a transceiver (110) for permitting access to a cellular communications system (100). The transceiver (110) is configured to transmit traffic to a communication node (101,120). The transceiver (110) receives a permission message from the communication node (101,120). The permission message indicates permission to a group of transceivers to transmit an access request message indicating a request to transmit the traffic to the communication node (101, 120). The transceiver (110) determines whether the transceiver (110) is comprised in the group of transceivers having permission to transmit the access request message based on the received permission message.
