摘要:
A method for handover is disclosed. The method comprises generation of mobility information that associates with a mobile device attached to a first access node. The mobility information is then communicated to a second access node for use in a handover of the mobile device from the first access node to the second access node.
摘要:
A method includes, at a user equipment, combining a message requesting the radio resource connection and a message requesting at least one service into a single message. The single message is transmitted from the user equipment to a network element in a wireless network. Another method includes receiving, from a user equipment, a single message including both a message requesting a radio resource connection and a message requesting at least one service. In response to the message requesting radio resource connection, performing radio resource control connection establishment for the user equipment in order to establish the radio resource control connection between the user equipment and at least one of a plurality of network elements of a wireless network. In response to the message requesting at least one service, performing service request procedures for the user equipment, wherein at least part of the radio resource control connection establishment and at least part of the service request procedures are performed in parallel.

When a Universal Terrestrial Radio Access Network (UTRAN) receives an indication on Layer 3 (L3) (an L1/L2 indication is also possible) from the User Equipment (UE) that it is switching the High Speed-Data Shared Channel (HS-DSCH) reception to another cell in the active set (AS), the UTRAN sends a reconfiguration message to the UE via the target cell using a pre-configured configuration that UE has taken into use. The message can only include an indication that the pre-defined configuration can be used further by the UE or that a complete new configuration is to be used, e.g., using new HARQ info or even a hard handover (HHO) to another frequency. After receiving the configuration message, the UE responds with a normal reconfiguration complete message.
摘要:
A new RRC Connected (mobility) state in which a UE utilizes a temporary identifier to monitor a downlink control channel in accordance with a discontinuous reception cycle; and maintains the new connected state, the discontinuous reception cycle and the temporary identifier while the UE re-selects to a second/serving access node which lies within a same designated reselection area as a first/source access node. The DRX cycle is maintained but re-aligned with a system frame number of the second access node; the temporary identifier is a CRNTI and the designated re-selection area is defined by all contiguous cells in which respective access nodes broadcast the CRNTI in system information; the UE re-selects to the second access node; and the UE enters the new connected mobility state automatically upon expiry of a time alignment timer or upon explicit network signaling while in a different connected state.
摘要:
A new protocol data unit is used in communications in a radio access network. When a user equipment requests a radio resource controller connection, the UE includes its identity in the request message. In establishing the connection to UE, a serving radio network controller allocates a logical channel to the UE for communications and identifies the logical channel in the header of the protocol data unit so as to allow a receiver of the PDU to know the UE identity in an out-of-band signaling fashion, depending upon a state of the transmitter of the PDU. When the transmitter changes its state, the receiver can change state accordingly. The new PDU structure allows continuous reception of the HS-DSCH downlink channel during state transition form CELL_FACH or CELL_PCH or URA_PCH to CELL_DCH and vice versa. This new PDU structure also allows continuous HS_DSCH retransmissions.

摘要:
The specification and drawings present a new method, system, apparatus and software product for improving the performance of an uplink communication utilizing a hybrid automatic repeat protocol (HARQ) by an HARQ failure indication over Iub-interface (e.g., from a node B to a radio network controller, RNC) in mobile communication networks including a number of HARQ retransmissions before said failure occurred.
摘要:
Because the current RRC: ACTIVE SET UPDATE message presently used in soft handover does not contain HS-DSCH related information, which could be utilized for a Serving HS-DSCH cell change, a separate Radio Bearer Control procedure is needed between the UE (10) and the RNC (20) for carrying out the Serving HS-DSCH cell change. Should HS-DSCH related information—applicable to Serving HS-DSCH cell change—be added to the RRC: ACTIVE SET UPDATE message (32), an unnecessary Radio Bearer Control procedure is avoided, and the drawbacks of the current method are overcome.
