Abstract
Various communication systems may benefit from proper handling of mobility. In particular, connected mode mobility may be suitably addressed for enhanced coverage user equipment. A method can include determining to attempt access to a target cell in enhanced coverage mode. The method can also include sending, based on the determination, a report to a source cell of an intent to access the target cell in enhanced coverage mode.

1-20. (canceled)
A method, comprising:
- initiating a handover at a user equipment from a source access node to a target access node;
- determining, by the user equipment, a coverage mode, wherein the coverage mode comprises a normal coverage mode or an enhanced coverage mode;
- and
- sending one of a contention-based random access channel preamble and a dedicated preamble to the target access node contingent on the coverage mode.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- wherein the at least one memory and the computer program code are configured, with the at least one processor, cause the apparatus at least to
- initiate a handover at a user equipment from a source access node to a target access node;
- determine, by the user equipment, a coverage mode, wherein the coverage mode comprises a normal coverage mode or an enhanced coverage mode;
- and
- send one of a contention-based random access channel preamble and a dedicated preamble to the target access node contingent on the coverage mode.
A computer program product comprising a computer-readable medium bearing computer program code embodied therein for use with a computer, the computer program code comprising:
- code for initiating a handover at a user equipment from a source access node to a target access node;
- code for determining, by a user equipment, a coverage mode, wherein the coverage mode comprises a normal coverage mode or an enhanced coverage mode;
- and
- code for sending one of a contention-based random access channel preamble and a dedicated preamble to the target access node contingent on the coverage mode.
