Detailed Description
The following detailed description is made with reference to the accompanying drawings and is provided to assist in a comprehensive understanding of various example embodiments of the disclosure. The following description includes various details to aid in understanding, but these are to be considered merely examples and are not intended to limit the disclosure, which is defined by the appended claims and their equivalents.

Those of ordinary skill in the art will recognize that various changes and modifications of the examples described herein can be made without departing from the spirit and scope of the present disclosure.
Fig. 1 schematically illustrates a schematic diagram of a multi-operator core network (MOCN) architecture. Under a multi-operator core network (MOCN) architecture, as shown in fig. 1, a plurality of mobile communication operators (e.g., china telecommunications, china mobile and/or china communication) may co-establish and share a communication base station and a communication cell/frequency point, and then respectively establish respective communication core networks on the basis of these, such as an operator 1 core network and an operator 2 core network shown in fig. 1.
The invention provides a multi-card terminal paging conflict coordination mechanism based on a co-building sharing scene, wherein under the condition of paging conflict, the paging conflict is avoided through coordination processing of a sharing base station.
Fig. 2 schematically illustrates a flow chart of a method for coordination of paging collision for a shared base station-based dual card terminal according to the present invention. Accordingly, fig. 3 schematically illustrates a signaling flow of a Paging Occasion (PO) coordination configuration mechanism in the shared base station-based dual card terminal paging collision coordination method according to the present invention.
In step S201, the multi-card terminal (e.g., a dual-card terminal) reports information about the mobile network to which its respective SIM card has access to the shared base station. Accordingly, the sharing base station receives information about mobile networks accessed by the respective SIM cards of the multi-card terminal reported by the multi-card terminal. The information about the mobile network to which the respective SIM card has access may for example comprise: whether the terminal is a dual card terminal; which operator network each SIM card in the terminal is connected to. The operator network is also called Public Land Mobile Network (PLMN). The shared base station is a base station shared by a plurality of operators under a multi-operator core network (MOCN) architecture. Typically, shared base stations are also built jointly by multiple operators. This step is shown in fig. 3 as the uppermost signaling from the dual card terminal to the shared base station.
Then, in step S202, the shared base station determines whether there is a collision of Paging Occasions (POs) corresponding to the respective SIM cards of the multi-card terminal.
When paging parameter Ns > =2, each paging radio frame contains more than one Paging Occasion (PO).
As a preferred example, the Paging Occasions (POs) correspond to subframes in the Paging Frame (PF), and the different Paging Occasions (PO) correspond to different subframes in the Paging Frame (PF).
For example, if Paging Occasions (PO) of two SIM cards of the dual card terminal are the same, and the Paging Occasions (PO) of the two SIM cards of the dual card terminal correspond to the same subframe in the Paging Frame (PF), the shared base station determines that there is a collision in the Paging Occasions (PO) of the respective SIM cards corresponding to the dual card terminal.
In the case where the shared base station determines that there is a collision of Paging Occasions (POs) corresponding to the respective SIM cards of the two-card terminal, the following processing is performed to solve the problem of paging collision of the two-card terminal.
Specifically, for example, in step S203, the sharing base station allocates different Paging Occasions (POs) to the respective SIM cards of the two-card terminal. For example, a PO coordination configuration mechanism at the network side is used to solve the paging collision problem, and a PO coordination configuration signaling is indicated to the dual-card terminal. For example, a conflicting PO may be assigned to one of the SIMs for use, while a non-assigned conflicting PO is PO adjusted and another PO is assigned to the non-assigned conflicting PO. Such a process is illustrated in fig. 3 as a process of "the base station finds a paging collision and performs paging collision coordination". As a preferred example, when the sharing base station allocates different Paging Occasions (POs) to respective SIM cards of a multi-card terminal (e.g., a dual-card terminal), conflicting Paging Occasions (PO) may be allocated to one SIM card and further different Paging Occasions (PO) to other SIM cards.
In step S204, the shared base station issues Paging Occasion (PO) configuration information to the two-card terminal. Such steps are illustrated in fig. 3 as intermediate signaling from the shared base station to the dual card terminal.
Further in step S205, after receiving the Paging Occasion (PO) configuration information, the dual card terminal completes the configuration and feeds back to the shared base station that the configuration has been completed. Accordingly, the shared base station receives feedback from the multi-card terminal that completed the configuration. Such a process is illustrated in fig. 3 as a process of "the UE receiving PO coordination configuration signaling and receiving a call in a configured PO subframe" and the lowest signaling from the dual card terminal to the shared base station. After the configuration is completed, each SIM card of the multi-card terminal receives a call at different Paging Occasion (PO) subframes allocated thereto, and paging collision can be avoided.
If the shared base station judges that there is no conflict in Paging Occasions (PO) corresponding to the respective SIM cards of the two-card terminal, the processing is directly ended. For example, paging Occasions (POs) of two SIM cards of the dual card terminal are different, for example, paging Occasions (PO) of two SIM cards of the dual card terminal correspond to different subframes in a Paging Frame (PF), and the sharing base station determines that there is no collision in Paging Occasions (PO) of the respective SIM cards corresponding to the dual card terminal.
The following specific examples illustrate how Paging Occasions (POs) corresponding to respective SIM cards of a multi-card terminal collide and how paging collision coordination is performed.
Fig. 4 schematically illustrates a case where Paging Occasions (POs) of two SIM cards of a dual card terminal collide and a manner of coordinating Paging Occasions (PO) of two SIM cards of the dual card terminal.
As shown in fig. 4, the Paging Frame (PF) is included in the DRX (discontinuous reception) cycle of the current device, and the subframe corresponding to the Paging Occasion (PO) is included in the Paging Frame (PF).
For example, SIM card 1 is china telecom and SIM card 2 is china Unicom. The co-established shared base station finds that the paging collision problem occurs in the subframe 5 and decides to allocate the subframe 5 to the china telecommunication SIM card, while the other configurable PO selection subframe 8 is used as the paging listening subframe of the china communication card.
Fig. 5 schematically illustrates a diagram for resolving Paging Occasion (PO) conflicts for two SIM cards of a two-card terminal.
As shown in fig. 5, the dual card terminal and the shared base station solve Paging Occasion (PO) conflicts of two SIM cards of the dual card terminal through steps 1 to 4 shown in the figure, so that finally, the PO selection subframe 5 is allocated to the china telecommunication SIM card, and the PO selection subframe 8 is allocated to the china communication SIM card, thereby successfully solving the Paging Occasion (PO) conflict.
The invention creatively utilizes the condition of network co-establishment sharing and solves the problem of paging conflict of the multi-card terminal through coordination processing among networks. More specifically, the invention introduces the specific design of multi-card terminal capability reporting and signaling, can lead the network side to actively find the paging conflict problem, and designs the coordination flow of the Paging Occasion (PO) of the shared base station to solve the paging conflict problem.
