Cell handover method and apparatus
View Patent ↗Cell handover method and apparatus are provided. The method applied to a first base station includes: transmitting a handover request message, wherein the handover request message includes a capacity indication message of a pre-configuration parameter; receiving a handover request acknowledgement message, wherein the handover request acknowledgement message includes the pre-configuration parameter, and a capacity of the pre-configuration parameter is determined based on the capacity indication message; and transmitting a handover command based on the handover request acknowledgement message. The method applied to a second base station includes: receiving a handover request message, wherein the handover request message includes a capacity indication message of a pre-configuration parameter; generating a handover request acknowledgement message based on the handover request message, wherein the handover request acknowledgement message includes the pre-configuration parameter, and a capacity of the pre-configuration parameter is determined based on the capacity indication message; and transmitting the handover request acknowledgement message.
1 . A cell handover method applied to a source base station, comprising:
transmitting a handover request message to at least one potential target base station, wherein the handover request message comprises an indicator indicating limited range of number of bits;
receiving a handover request acknowledgement message from the at least one potential target base station, wherein the handover request acknowledgement message comprises at least one to-be-configured parameter having a capacity that is configured by the at least one potential target base station based on the limited range of number of bits, and the at least one to-be-configured parameter is used for cell handover of a User Equipment (UE), wherein the capacity of the at least one to-be-configured parameter does not exceed the limited range of number of bits; and
transmitting a handover command that comprises the at least one to-be-configured parameter to the UE based on the handover request acknowledgement message.
2 . The method according to claim 1 , wherein said transmitting the handover request message comprises:
transmitting the handover request message comprising the limited range of number of bits and a current configuration parameter; and/or
transmitting the handover request message comprising the limited range of number of bits, a current configuration parameter, and a handover trigger condition.
3 . The method according to claim 1 , wherein said transmitting the handover command based on the handover request acknowledgement message comprises:
obtaining the at least one to-be-configured parameter based on the handover request acknowledgement message; and
transmitting the handover command via Radio Resource Control (RRC) signaling.
4 . The method according to claim 3 , wherein the RRC signaling comprises at least one to-be-configured parameter of at least one candidate cell.
5 . A cell handover method applied to a potential target base station, comprising:
receiving a handover request message from a source base station, wherein the handover request message comprises an indicator indicating limited range of number of bits;
generating a handover request acknowledgement message based on the handover request message, wherein the handover request acknowledgement message comprises at least one to-be-configured parameter used for cell handover of a User Equipment (UE), and a capacity of the at least one to-be-configured parameter does not exceed the limited range of number of bits; and
transmitting the handover request acknowledgement message to the source base station.
6 . The method according to claim 5 , wherein the handover request message further comprises a current configuration parameter, and/or a handover trigger condition.
7 . A cell handover apparatus, comprising:
a processor; and
a memory storing processor-executable instructions,
wherein the processor is configured to:
transmit a handover request message to at least one potential target base station, wherein the handover request message comprises an indicator indicating limited range of number of bits;
receive a handover request acknowledgement message from the at least one potential target base station, wherein the handover request acknowledgement message comprises at least one to-be-configured parameter having a capacity that is configured by the at least one potential target base station based on the limited range of number of bits, and the at least one to-be-configured parameter is used for cell handover of a User Equipment (UE), wherein the capacity of the at least one to-be-configured parameter does not exceed the limited range of number of bits; and
transmit a handover command that comprises the at least one to-be-configured parameter to the UE based on the handover request acknowledgement message.
8 . A cell handover apparatus, comprising:
a processor; and
a memory storing processor-executable instructions,
wherein the processor is configured to perform the method of claim 5 .
9 . A non-volatile computer-readable storage medium having computer instructions stored therein, wherein when the computer instructions are executed by a processor, the method of claim 1 is performed.
10 . A non-volatile computer-readable storage medium having computer instructions stored therein, wherein when the computer instructions are executed by a processor, the method of claim 5 is performed.
