Problems solved by technology

In this case, access bursts will still be sent even though TA is provided in the HO command, due to the physical properties of GSM L1, e.g. the first four uplinks due to diagonal interleave Time slots cannot be used for voice / data transmission

Embodiment Construction

[0046] In general, examples of the present invention are described in the context of ongoing LTE work (see, eg, 3GPP TR 25.913, V7.3.0 (2006-03), Requirements for Evolved UTRA (E-UTRA) and Evolved UTRAN (Release 7)) sexual implementation.

[0047] An unresolved problem of E-UTRAN is how to access a new cell when providing the TA to be used in the target cell when HO is provided. When no timing advance is provided, it has been proposed that the UE will use the UL resources of the target cell to send access bursts to allow the NW to evaluate the timing advance to be used by the UE (in a similar manner as in GERAN). Note that in the HO command, the identity of the UE in the new (target) cell is also provided: eg the C-RNTI of the UE in the target cell is given in the HO command.

Abstract

A method is described which provides a synchronized HO of a mobile device. The method includes receiving a HO command. A determination is made of whether the HO command includes an indication of UL resource allocations. A C-RNTI is waited for in DL signaling if the HO command does not include the indication of UL resource allocations. If the HO command includes the indication of UL resource allocations, transmitting occurs based on the UL resource allocations. The method may be performed as a result of execution of computer program instructions stored in a computer readable memory medium. An apparatus is also described.
