Abstract

Example implementations relate to devices, methods, and computer program products of communication networks in relation to, e.g., involved in initial access from an idle status, connection reestablishment, handover, or synchronization. A terminal apparatus may include: a control module configured to detect receipt of a group information indicative of a group of at least two network apparatuses, the group information being descriptive for a certain configuration of communication parameters enabling the terminal apparatus to communicate with anyone of the network apparatuses of the respective group, and request connecting to at least one of the network apparatuses of the group by use of the certain configuration.

Claims8

Dependent claims

A network apparatus comprising a control module configured to:

transmit, by the network apparatus in a single frequency network fashion, an area broadcast control channel including a group information for a group of at least two network apparatuses and configuration information for a certain configuration that is adapted to connect the terminal apparatus to any network apparatus of the group, wherein the certain configuration includes permission to perform autonomous handover to any of the network apparatuses of the group, and wherein the single frequency network fashion involves two or more of the network apparatuses of the group transmitting their respective broadcast control channel in a predetermined resource;
detect, by the network apparatus, receipt of a connection request including the group information transmitted by a terminal apparatus using the certain configuration which is adapted to connect the terminal apparatus to any network apparatus of the group;
based on the group information received from the terminal apparatus, permit, by the network apparatus, the terminal apparatus to connect and use the certain configuration for communicating with the network apparatus;
receive, by the network apparatus from the terminal apparatus, a cell change indication message containing the group information for an autonomous handover to another network apparatus of the group;
and
transmit, by the network apparatus to the terminal apparatus, an acknowledgement for the cell change indication.

A method for operating a network apparatus, comprising:

transmitting, by the network apparatus in a single frequency network fashion, an area broadcast control channel including a group information for a group of at least two network apparatuses and configuration information for a certain configuration that is adapted to connect the terminal apparatus to any network apparatus of the group, wherein the certain configuration includes permission to perform autonomous handover to any of the network apparatuses of the group, and wherein the single frequency network fashion involves two or more of the network apparatuses of the group transmitting their respective broadcast control channel in a predetermined resource;
detecting, by the network apparatus, receipt of a connection request including the group information transmitted by a terminal apparatus using the certain configuration which is adapted to connect the terminal apparatus to any network apparatus of the group;
based on the group information received from the terminal apparatus, permitting, by the network apparatus, the terminal apparatus to connect and use the certain configuration for communicating with the network apparatus;
receiving, by the network apparatus from the terminal apparatus, a cell change indication message containing the group information for an autonomous handover to another network apparatus of the group;
and
transmit, by the network apparatus to the terminal apparatus, an acknowledgement for the cell change indication.
