Embodiment 1

[0038] The operator PLMN ID delivery method provided by the embodiment of the present invention, such as figure 2 shown, including:

[0039] S201. If the PLMN list of the SIB1 broadcast by the base station does not include the PLMN ID of the main operator of the base station, add the PLMN ID of the main operator of the base station to the SIB1.

[0040] It may be to add the primary operator's PLMN ID to the first place in the PLMN list of SIB1.

[0041]Here, the PLMN ID of the primary operator of the base station can be added to the PLMN list of SIB1; or, can also be added to a PLMN information element in SIB1.

[0042] S202. Broadcast the SIB1.

[0043] Since the SIB1 includes the PLMN ID of the primary operator of the base station, the UE can acquire the PLMN ID of the primary operator of the base station from the SIB1.

[0044] The operator PLMN ID delivery method provided by Embodiment 1 of the present invention ensures that the broadcast SIB1 includes the PLMN ID of t...

Embodiment 2

[0046] Embodiment 2 of the present invention adopts the method for issuing the operator's PLMN ID provided in Embodiment 1, and uses an ANR algorithm switching process as an example for illustration. like image 3 As shown, its method steps include:

[0047] S301. The UE reports the A3 event to the serving eNB, and reports the PCI of the target eNB (that is, the eNB of the neighboring cell). The A3 event here refers to an intra-frequency handover event. Further reference may be made to the provisions of the 3GPP protocol (refer to 3GPP TS 36.331V9.6.0 (2011-03), section 5.5).

[0048] S302. The serving eNB delivers a CGI measurement control message for the target eNB to the UE.

[0049] S303. The UE searches for the SIB1 of the target eNB, and reports the CGI of the target eNB to the serving eNB.

[0050] Specifically, in step S303, if the S1 link between the target eNB and the main operator MME fails or other circumstances cause the PLMN list in the SIB1 that the target e...

Embodiment 3

[0059] Embodiment 3 of the present invention provides a user equipment, such as Figure 4 shown. The user equipment includes a processor 40, and common components such as a storage component memory, a screen, an antenna, and an input / output interface I / O. These general components are not shown in the figure. Wherein, the processor can read and run the program, so that the aforementioned method embodiments can be executed in the user equipment.

[0060] The processor 40 may include:

[0061] The reporting unit 401 is configured to report the A3 event to the serving eNB, and report the PCI of the target eNB; fill in the obtained PLMN ID of the main operator of the target eNB into the CGI, and report it to the serving eNB.

[0062] The receiving unit 402 is configured to receive a CGI measurement control message for the target eNB issued by the serving eNB; receive a handover request for the handover target eNB issued by the serving eNB according to the CGI, and the handover r...

Abstract

A method, a base station and user equipment for issuing operator public land mobile network identification are disclosed, relate to the field of communication, and aim at solving a problem that on a carrier-frequency share scene, UE cannot shift to a targeted eNB due to that the UE cannot obtain a correct PLMN ID of the primary operator of a targeted eNB. The method comprises that: if a PLMN list of a system information module SIB1 which is to be broadcasted by the base station does not include the PLMN ID of the primary operator of the base station, then the PLMN ID of the primary operator of the base station should be added to the SIB1, and then the SIB1 is broadcasted.

Description

technical field [0001] The present invention relates to the field of communications, and in particular to a method for issuing an operator's public land mobile network identifier, a base station and user equipment. Background technique [0002] The earliest demand for network sharing came from Europe. By sharing network resources among operators, the purpose of saving cost and investment can be achieved. At the same time, the cycle of network construction can be greatly shortened, and the coverage of operators can be effectively increased. Currently, there are two network sharing architectures in the industry: access network sharing and gateway sharing. Carrier frequency sharing is one of the modes of access network sharing. [0003] In the carrier frequency sharing mode, the hardware resources and carrier frequency of the eNB (base station) are shared by multiple operators. Each base station cell is shared by multiple operators. The core network of each operator is indep...
