Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
The current technology is to configure different proprietary priority reselection schemes of different operators PLMN for different network UEs, and to send RRC release messages to the UEs to carry the proprietary frequency point priority for reselection. However, the existing technology adopting the special reselection priority has some disadvantages, and the problem that the unified and consistent effective reselection priority control cannot be realized on the terminal exists.
The 5G access network is also referred to as NR technology and the 4G access network is also referred to as LTE technology. The NR and LTE both broadcast a common radio resource control message in a wireless network in a sib (system information broadcast) system message broadcast manner, and are used for issuing common configuration parameters of the UE in a cell to control the behavior of the UE.
In LTE, SIB3 carries common parameters for reselection of the local cell, including intra-band reselection, inter-band reselection, and inter-system reselection, SIB5 carries dedicated parameters for inter-band reselection, SIB6 carries dedicated parameters for reselection to an UTRA inter-system, SIB7 carries dedicated parameters for reselection to a GERAN inter-system, SIB8 carries dedicated parameters for reselection to a CDMA2000 inter-system, and SIB24 carries dedicated parameters for reselection to an NR inter-system.
The SIB2 in NR carries common parameters for reselection of the cell, including intra-band reselection, inter-band reselection, and inter-system reselection, the SIB4 carries dedicated parameters for inter-band reselection, and the SIB5 carries dedicated parameters for reselection to an NR different system.
In order to solve the problem that uniform and effective reselection priority control cannot be implemented on a terminal when a dedicated reselection priority is adopted, as shown in fig. 1, a PLMN-based cell common reselection priority broadcasting method according to this embodiment includes:
judging whether the cell is a shared cell;
if the shared cell is adopted, judging whether the PLMN common reselection priority is adopted;
if so, configuring public reselection priority based on the PLMN in a broadcasting mode; if not, the dedicated priority is configured by RRC Release.
Specifically, the method for configuring the public reselection priority based on the PLMN in the present embodiment by using a broadcast manner is as follows:
the reselection priorities cellreselection priority and cellreselection priority of the serving cell carried in the NR SIB2 carry PLMN information, and different PLMNs may be configured with different cellreselection priorities and cellreselection priorities.
The NR SIB4 carries the reselection priority of the inter-frequency point, and different frequency points carry different cellreselection priorities and cellreselection priorities, and carry PLMN information. Different PLMNs may be configured with different cellselectionpriority and cellselectionsubpriority.
The NR SIB5 carries reselection priorities of different system EUTRA frequency points, and different frequency points carry different cellreselection priorities and cellreselection priorities, and carry PLMN information. Different PLMNs may be configured with different cellselectionpriority and cellselectionsubpriority.
The reselection priority cellreselection priority of the serving cell carried in the LTE SIB3 carries PLMN information, and different PLMNs may configure different cellreselection priorities.
The LTE SIB5 carries the reselection priority of the inter-frequency point, and different frequency points carry different cellreselection priorities and PLMN information. Different PLMNs may be configured with different cellreselection priorities.
The LTE SIB6 carries the reselection priority of the UTRA frequency point in the different system, and different frequency points carry different cellreselection priorities and PLMN information. Different PLMNs may be configured with different cellreselection priorities.
The LTE SIB7 carries the reselection priority of the inter-system GERAN frequency point, and different frequency points carry different cellReselection priorities and PLMN information. Different PLMNs may be configured with different cellreselection priorities.
The LTE SIB8 carries the reselection priority of the frequency point of CDMA2000 in the different system, and different frequency points carry different cellreselection priorities and PLMN information. Different PLMNs may be configured with different cellreselection priorities.
The LTE SIB24 carries reselection priorities of the NR frequency points of the different systems, and different frequency points carry different cellreselection priorities and PLMN information. Different PLMNs may be configured with different cellreselection priorities.
For example, for the NR SIB2/4/5, broadcasting PLMN-based reselection priorities may take the form of:
PLMN1：{cellReselectionPriority，cellReselectionSubPriority}
PLMN2：{cellReselectionPriority，cellReselectionSubPriority}
……
the following forms may also be adopted:
cellReselectionPriorityInfo{PLMN1，cellReselectionPriority
cellReselectionSubPriority}
cellReselectionPriorityInfo{PLMN2，cellReselectionPriority
cellReselectionSubPriority}
……
for example, the 5G shared cell operates at the frequency point 3349.98MHz and supports telecommunication PLMN 46011 and unicom PLMN 46002. The Unicom 5G cell works at the frequency point 3550MHz, the telecom 5G cell works at the frequency point 3450MHz, the Unicom 4G cell works at the frequency point 1850MHz, and the telecom 4G cell works at the frequency point 1870 MHz. A PLMN-based common reselection priority broadcast is in the form of:
SIB2：cellReselectionPriorityInfo{46011，5，0}
cellReselectionPriorityInfo{46002，5，0}
SIB4：3450MHz cellReselectionPriorityInfo{46011，6，0}
3550MHz cellReselectionPriorityInfo{46002，6，0}
SIB5：1870MHz cellReselectionPriorityInfo{46011，4，0}
1850MHz cellReselectionPriorityInfo{46002，4，0}
