Abstract
The embodiments of the present invention disclose a method for establishing a cell reselection list is provided. A network and a terminal establish frequency indexes for the cell reselection list, so that when a network side delivers an RAT and frequency priority information, the priority information may be delivered according to frequency indexes in a frequency list, thus implementing cell reselection that is based on the priority for the terminal.
Claims12
An apparatus, comprising a processor coupled with a non-transitory storage medium storing executable instructions;
- wherein the executable instructions, when executed by the processor, cause the processor to:
- obtain a cell modification message from a network, wherein the cell modification message includes neighbor cell information indicating information of at least one cell neighboring a serving cell of a user equipment for performing a measurement by the UE of the at least one neighboring cell, the cell modification message being a packet measurement order (PMO) message or a packet cell change order (PCCO) message;
- update a general packet radio service (GPRS) 3G cell reselection list by performing:
- modifying a 3G neighbor cell list according to the neighbor cell information in the cell modification message to obtain a modified 3G neighbor cell list;
- and
- updating the GPRS 3G cell reselection list according to the modified 3G neighbor cell list to obtain an updated GPRS 3G cell reselection list used for cell reselection,
- wherein the updated GPRS 3G cell reselection list comprises frequency(s) and/or cell information in the modified 3G neighbor cell list.
An apparatus, comprising a processor coupled with a non-transitory storage medium storing executable instructions;
- wherein the executable instructions, when executed by the processor, cause the processor to:
- obtain a system message, wherein the system message comprises a first system message and optionally further comprises a second system message, the first system message comprises frequency information used in a 3G neighbor cell list, and when the system message further comprises the second system message, the second system message comprises frequency information that is used in a cell reselection list but not used in the 3G neighbor cell list;
- establish a cell reselection list and/or a frequency list according to the system message;
- establish indexes in ascending order in the cell reselection list and/or the frequency list according to an appearance order from first to last of the frequency information that is used in the 3G neighbor cell list in the system message;
- when the system message further comprises the second system message that comprises the frequency information that is used in the cell reselection list but not used in the 3G neighbor cell list, establish indexes at bottom of the cell reselection list and/or the frequency list according to an appearance order from first to last of the frequency information that is used in the cell reselection list but not used in the 3G neighbor cell list in the second system message;
- and
- when the first system message further comprises the frequency information that is used in the cell reselection list but not used in the 3G neighbor cell list,
- establish the indexes in descending order for the frequencies that are used in the cell reselection list but not used in the 3G neighbor cell list in the first system message, and
- establish the indexes in descending order for the frequencies of the second system message via obtaining subsequent values of the indexes.
