Abstract

Embodiments of the present disclosure provide a method for selecting a public land mobile network PLMN, and an apparatus and a device for same. The method includes: during a process of selecting a network by a mobile terminal, if it is learned by means of determining that a registered public land mobile network RPLMN and a home public land mobile network HPLMN correspond to the mobile terminal are unavailable, acquiring a PLMN network in a PLMN list pre-stored in the mobile terminal, to perform a registration, wherein the PLMN list includes network information of one or more other PLMN networks that are selected and successfully registered.

Claims

1-15. -15. (canceled)

16. A method for selecting a public land mobile network (PLMN), comprising:

during a process of selecting a network by a mobile terminal, if it is learned by means of determining that a registered public land mobile network (RPLMN) and a home public land mobile network (HPLMN) correspond to the mobile terminal are unavailable, acquiring a PLMN network in a PLMN list pre-stored in the mobile terminal to perform a registration, wherein the PLMN list comprises network information of one or more other PLMN networks that are selected and successfully registered.

17. The method according to claim 16, wherein the network information of the one or more other PLMN networks that are selected and successfully registered comprises the network information of the one or more other PLMN networks that are manually selected by a user and successfully registered.

18. The method according to claim 17, wherein the network information comprises a mobile country code (MCC), a mobile network code (MNC), and standard information that correspond to the PLMN network.

19. The method according to claim 18, wherein the network information of each PLMN network comprised in the PLMN list is dynamically adjusted according to a least recently used (LRU) algorithm.

20. The method according to claim 17, wherein the method further comprises:

during the process of manually selecting a PLMN network by the user, identifying an unavailable PLMN network among found PLMN networks.

21. The method according to claim 18, wherein the method further comprises:

during the process of manually selecting a PLMN network by the user, identifying an unavailable PLMN network among found PLMN networks.

22. The method according to claim 19, wherein the method further comprises:

during the process of manually selecting a PLMN network by the user, identifying an unavailable PLMN network among found PLMN networks.

23. The method according to claim 20, wherein after the identifying an unavailable PLMN network among all found PLMN networks, the method further comprises:

displaying the PLMN networks in the following sequence;

an HPLMN or an equivalent home public land mobile network (EHPLMN), a PLMN list, a user controlled public land mobile network (UPLMN) or an operator controlled public land mobile network (OPLMN), an RPLMN, other PLMNs, and a forbidden public land mobile network (FPLMN), wherein the FPLMN is an unavailable PLMN.

24. The method according to claim 23, wherein the other PLMNs are sorted according to following steps:

randomly sorting, according to signal strength, PLMNs whose signal strength is higher than a preset value; and

sorting, according to signal strength in descending order, PLMNs whose signal strength is lower than the preset value.

25. An apparatus for selecting a public land mobile network (PLMN), comprising:

a memory storing instructions; and

a processor coupled to the memory to execute the instructions to;

during a process of selecting a network by a mobile terminal, if it is learned by means of determining that a registered public land mobile network (RPLMN) and a home public land mobile network (HPLMN) correspond to the mobile terminal are unavailable, acquire a PLMN network in a PLMN list pre-stored in the mobile terminal to perform a registration, where the PLMN list includes network information of one or more other PLMN networks that are selected and successfully registered.

26. The apparatus according to claim 25, wherein the network information of the one or more other PLMN networks that are selected and successfully registered comprises the network information of the one or more other PLMN networks that are manually selected by a user and successfully registered.

27. The apparatus according to claim 26, wherein the network information comprises a mobile country code (MCC), a mobile network code (MNC), and standard information that correspond to the PLMN network.

28. The apparatus according to claim 27, wherein the network information of each PLMN network included in the PLMN list is dynamically adjusted according to a least recently used (LRU) algorithm.

29. The apparatus according to claim 26, wherein the processor further executes the instructions to:

during a process of manually selecting a PLMN network by the user, identify an unavailable PLMN network among found PLMN networks.

30. The apparatus according to claim 27, wherein the processor further executes the instructions to:

during a process of manually selecting a PLMN network by the user, identify an unavailable PLMN network among found PLMN networks.

31. The apparatus according to claim 28, wherein the processor further executes the instructions to:

during a process of manually selecting a PLMN network by the user, identify an unavailable PLMN network among found PLMN networks.

32. The apparatus according to claim 29, wherein the processor further executes the instructions to:

display all the PLMN networks in the following sequence;

an HPLMN or an equivalent home public land mobile network (EHPLMN), a PLMN list, a user controlled public land mobile network (UPLMN) or an operator controlled public land mobile network (OPLMN), an RPLMN, other PLMNs, and a forbidden public land mobile network (FPLMN), wherein the FPLMN is an unavailable PLMN.

33. The apparatus according to claim 32, wherein the processor further executes the instructions to:

randomly sort, according to signal strength, PLMNs whose signal strength is higher than a preset value; and

sort, according to signal strength in descending order, PLMNs whose signal strength is lower than the preset value.

34. A mobile terminal, comprising:

a memory storing instructions; and

a processor coupled to the memory to execute the instructions to;

during a process of selecting a network by a mobile terminal, if it is learned by means of determining that a registered public land mobile network (RPLMN) and a home public land mobile network (HPLMN) correspond to the mobile terminal are unavailable, acquire a PLMN network in a PLMN list pre-stored in the mobile terminal to perform a registration, wherein the PLMN list comprises network information of one or more other PLMN networks that are selected and successfully registered.
