Abstract
The method and apparatus as described are directed toward techniques and mechanisms to improve efficiency in wireless communication networks through optimization of handover scenarios. Determining whether an intra-base station or inter-node-B handover is too performed, and determining the protocol layers to reset during the handover based at least in part on the type of handover to be performed increases the overall efficiency of the wireless network.
Claims35
A method for performing a handover in a wireless communication system comprising:
- determining whether an intra-base station handover or an inter-base station handover is to be performed;
- generating a handover command comprising a plurality of instruction fields, each of the instruction fields corresponding to one of a plurality of user plane communication protocols and indicating whether the corresponding one of the plurality of user plane communication protocols is to be reset;
- instructing a terminal to perform the handover based on the instruction fields without resetting at least one of the user plane communication protocols if the intra-base station handover is to be performed;
- and
- instructing the terminal to perform the handover based on the instruction fields while resetting at least one of the user plane communication protocols if the inter-base station handover is to be performed.
