Abstract:
1. A method for processing a measurement context, comprising: processing a network-side measurement context between a source radio access network device and a destination radio access network device when a User Equipment (UE) in a Long Term Evolution system switches from the source radio access network device to the destination radio access network device through an inter-frequency switching or an inter-frequency Radio Resource Control (RRC) connection reestablishment, wherein the source radio access network device is a radio access network device serving the UE prior to the inter-frequency switching or the inter-frequency RRC connection reestablishment; and the destination radio access network device is a radio access network device serving the UE after the inter-frequency switching or the inter-frequency RRC connection reestablishment, and the network-side measurement context comprises measurement objects and measurement identities, and wherein the processing the network-side measurement context between the source radio access network device and the destination radio access network device comprises: the source radio access network device transmitting the network-side measurement context on the source radio access network device to the destination radio access network device, and the destination radio access network device performing network-side measurement context exchange operations on the received network-side measurement context from the source radio access network device upon determining that the UE is subject to the inter-frequency switching or the inter-frequency RRC connection reestablishment, wherein the exchange operations comprises: locating all measurement identities associated with measurement objects corresponding to destination frequencies and associating the located measurement identities onto measurement objects corresponding to source frequencies; and locating all measurement identities associated with measurement objects corresponding to the source frequencies and associating the located measurement identities onto measurement objects corresponding to the destination frequencies, wherein the source frequencies are frequencies of a cell where the UE resides prior to the inter-frequency switching or the inter-frequency RRC connection reestablishment; and the destination frequencies are frequencies of a cell where the UE resides after the inter-frequency switching or the inter-frequency RRC connection reestablishment.
