[41] Mode for carrying out the invention

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. example.

FIG. 1 is a schematic flowchart of a method for acquiring a global identifier of a cell according to an embodiment of the present invention; as shown in FIG. 1, the method in this embodiment may include the following steps.

[44] Step S100: Receive gap information from a base station device in a serving cell, and receive a neighbor broadcast message from a base station device in the neighboring cell;

[45] In a specific implementation, the neighboring cell broadcast message is a cell adjacent to the serving cell (hereinafter referred to as a neighboring cell, where the neighboring cell and the serving cell may be the same frequency or different frequency phase). The base station device in the neighboring cell) sends. The neighboring cell and the serving cell may be in the same network system or in different network systems, for example, the serving cell and the neighboring cell are both cells in LTE, or the serving cell and the phase Neighboring cells are wideband code division multiple access networks (WCDMA, Wideband Code Division Multiple)

The cell in the access, or the serving cell is the cell in the LTE, and the neighboring cell is a cell in WCDMA.

[46] Step S101, reading a main information block (M1 B, Main Information Block) in the neighboring area broadcast message, and acquiring a system information block (SIB, the neighboring area) in the neighboring area broadcast message System

Information Block) location and repetition period.

[47] For example, a user equipment (such as a mobile phone) reads an MIB in the neighbor broadcast message, acquires a location and a repetition period of the SIB of the neighboring cell. The location of the SIB may be the frame number of the SIB. For example, when the serving cell and the neighboring cell are both in the LTE, the location of the acquired SIB is SIB1. The fifth subframe number continues for lms, and the repetition period of the SIB1 is 20 ms. Then, the length of the inter-turn gap may be 6 ms, and the repetition period that occurs may be 40 ms; when the serving cell and the neighbor The area is a cell in the WC DMA, the length of the inter-turn gap may be 80 ms, and the repetition period that occurs may be an integer multiple of 80 ms.

[48] Step S102, the user equipment (such as a mobile phone) reads the system information block SIB of the neighboring area according to the location and the repetition period of the acquired system information block SIB, according to the inter-turn gap inter-segment The SIB of the neighboring cell acquires the CGI of the neighboring cell and reports it to the serving cell.

[49] In this embodiment, the global identification of the neighboring cells in the same system or the neighboring cells in the adjacent system can be read through the inter-turn gap, thereby realizing the automatic discovery of the neighboring cells.

FIG. 2 is a schematic flowchart of another method for acquiring a global identifier of a cell according to another embodiment of the present invention; the method in this embodiment may be applicable to a scenario in which a serving cell and a neighboring cell are both located in an LTE network, specifically, As shown in FIG. 2, the method for acquiring a global identifier of a cell in this embodiment includes the following steps.

[51] Step S200, the base station device in the serving cell specifies a gap gap to the UE;

[52] Step S201: The UE performs frame synchronization on the neighboring cell in the inter-cell gap gap, and learns the system frame number and the subframe number in the current neighboring cell;

[53] Step S202: The UE determines whether the MIB of the neighboring cell can be read in the gap between the gaps.

[54] For example,

The UE determines whether the 6ms inter-segment that occurs every 40ms of the inter-turn gap gap overlaps with the MIB that appears once every 10ms in the neighboring frame on the inter-turn axis, and if so, confirms that it can read the The MIB of the neighboring cell is executed, and step S203 is performed. Otherwise, step S206 is performed.

[55] Step S203, the UE acquires the frame number of the SIB1 of the neighboring cell (for example, the fifth subframe of the frame) in the MIB, and acquires the lms of the SIB1 that appears once every 20 ms in the neighboring frame. The cycle information may be repeated, and the number of subframe deviations of the inter-turn gap gap and SIB 1 may also be acquired, and then step S204 is performed.

[56] Step S204, the UE determines whether the SIB1 of the neighboring area can be read in the gap between the gaps.

[57] For example, the UE determines whether the 6 ms that occurs every 40 ms of the inter-turn gap gap overlaps with the lms that occurs once every 20 ms of the SIB1 in the neighboring frame, and if so, the confirmation can be read. Step S205 is performed to the SIB of the neighboring cell, otherwise, step S208 is performed.

[58] Step S205, the UE reads the SIB1 of the neighboring cell in the inter-turn gap gap, and obtains the SIB1 according to the SIB. The CGI of the neighboring cell is reported to the serving cell, and the process ends.

[59] Step S206: The UE feeds back the number of subframe deviations of the gap between the gap and the location of the MIB of the neighboring cell to the base station device in the serving cell, and then performs step S207.

[60] Step S207: The base station device in the serving cell deactivates the original gap, and according to the returned subframe deviation number

, reconfigure a new gap, such as reconfiguring the start subframe number (startSubFrameNumber) parameter of the gap

, and activate a new gap, and perform step S204.

[61] Step S208: The base station device in the serving cell deactivates the original gap, and reconfigures a new gap according to the number of frame deviations and subframe deviations of the returned original gap and the SIB of the neighboring cell, for example, reconfigurable gap The system frame number (startSFN) and startSubFrameNumber (start subframe number) parameters are started, and a new gap is activated, and step S205 is performed.

[62] In the embodiment, in the LTE network, the serving cell can automatically detect the neighboring cell in the LTE network by specifying a gap to the terminal device to read the global identity information of the cell in the neighboring cell in the same network system.

FIG. 3 is a schematic flowchart of another method for acquiring a global identifier of a cell according to another embodiment of the present invention; the method in this embodiment may be applicable to a serving cell and a neighboring cell being located in the same communication system or respectively located in different communications. The system, for example, the scenario where the serving cell and the neighboring cell are located in the LTE network, or the serving cell is located in the L TE network, and the neighboring cell is located in the WCDMA network, or the serving cell and the neighboring cell are located in the WCDM A network, specifically, such as As shown in FIG. 3, the method for obtaining a global identifier of a cell in this embodiment includes:

[64] Step S300, the base station device in the serving cell allocates a gap (gap) to the terminal (UE), and sends the gap to the corresponding UE, where the length of the inter-turn gap gap is greater than or equal to that in the neighboring area broadcast message. The repetition period of the MIB.

[65] For example, when the serving cell and the neighboring cell are both located in the LTE network, and the period of the MIB in the neighboring cell broadcast message is 10 ms, the length of the gap allocated by the serving cell to the neighboring cell is greater than or equal to 10 ms. When the serving cell is located in the LTE network, and the neighboring cell is located in the WCDMA network, or the serving cell and the neighboring cell are both located in the WCDMA network, and the period of the MIB in the neighboring area broadcast message is 80 ms, the serving cell is The length of the gap allocated by the neighboring area is greater than or equal to 80 ms. In this way, the first gap allocated by the UE in the serving cell can be read to read the MIB information of the neighboring cell, and then the location and repetition period of the SIB of the neighboring cell can be obtained in the first gap interval allocated by the serving cell. .

[66] Step S301: The UE acquires a location and a repetition period of the SIB of the neighboring cell in the MIB. For example, when the serving cell and the neighboring cell are both located in the LTE network, the UE acquires a frame number of the neighboring cell SIB1 (for example, a fifth subframe of the frame) in the MIB, and acquires the The repetition period information of the lms that occurs once every 20 ms of the neighboring cell frame by SIB1, and the number of subframe deviations of the inter-chamber gap gap and SIB1 are acquired. When the serving cell is located in the LTE network, and the neighboring cell is located in the WCDMA network, or the serving cell and the neighboring cell are located in the WCDMA network, the location and period of acquiring the SIB3 in the WCDMA network are set by the device vendor, when read The MIB information 吋, the location and the repetition period of the SIB3 can be obtained from the MIB information, and the public terrestrial wireless network identifier (PLMNID) of the WCDMA network can also be obtained.

Step S302, the UE determines whether the SIB (SIB1 or SIB 3) of the neighboring area can be read in the gap between the gaps. If yes, go to step S303, otherwise, go to step S304.

For example, when the SIB is SIB1, the UE determines whether the 6 ms that occurs every 40 ms of the inter-turn gap gap overlaps with the SIB1 that occurs every 20 ms of the neighbor frame on the inter-turn axis, and if so, It is confirmed that the SIB of the neighboring area can be read, and step S303 is performed; otherwise, step S304 is performed. When the SIB is SIB3 吋, the criterion for judging refers to the foregoing SIB1 practice. The general criterion is: judging whether the inter-turn gap gap interval overlaps with the position where the SIB appears, and if so, confirms that After reading the SI B of the neighboring cell, step S303 is performed; otherwise, it is determined that the SIB of the neighboring cell cannot be read, and step S304 is performed.

[70] Step S303, the UE reads the SIB (SIB1 or SIB3) of the neighboring cell in the gap between the gaps, and obtains the CGI information of the neighboring cell according to the SIB and reports the CGI information to the serving cell. In another embodiment of the present invention, the cell global identifier information of the SIB3 includes: an ID of the local cell and an ID of the neighboring area radio network controller, and the process ends.

[71] Step S304: The base station device in the serving cell deactivates the original gap, and re-allocates the new gap according to the returned second location deviation information of the original gap and the location of the MIB of the neighboring cell, and activates the new gap. Step S303 is performed.

[72] For example, when the SIB is SIB1, the frame offset and the number of subframe offsets of the original gap and the neighboring MIB are returned, and the gap is reconfigured, and the initial system frame numbers startSFN and startSubFrame of the gap can be reconfigured. Number (starting subframe number) parameter; When the SIB is SIB3吋, the number of frame deviations and slot deviations of the original gap and the neighboring area M1 B are returned, and the gap is reconfigured, which can be reconfigured. The startSFN and the s tartSubFrameNumber parameter of the gap. [73] In this embodiment, in the LTE network system, the serving cell can obtain the global identification information of the cell in the neighboring cell in the same system or in the different system by specifying the gap to the terminal device, and the embodiment can implement the neighboring cell of the same network system. Automatic discovery or automatic discovery of neighbors between different network systems.

In the embodiment of the present invention, the network neighbor relationship is established by the RCN of the serving cell to implement the neighbor relationship list, and the RNC sends the gap gap to the UE, instructing the UE to read the same network system or different. The neighboring cell identifier of the network system is reported to the serving cell RNC, and the RNC of the serving cell automatically generates and optimizes the neighbor relationship according to the reporting result of the UE. The structure of the UE in the embodiment of the present invention will be described below by way of an embodiment.

And the value of the inter-turn gap, when the serving cell and the neighboring cell are both in the LTE cell, the length of the inter-turn gap may be 6 ms, and the repetition period may be 40 ms; The cell and the neighboring cell are both cells in WCDMA, the length of the inter-turn gap may be 80 ms, and the repetition period that occurs may be an integer multiple of 80 ms.

For example, the serving cell and the neighboring cell are both in the LTE network, or the serving cell and the neighboring cell are both in the WC DMA network, or the serving cell is in the LTE. The cell, the neighboring cell is a cell in WCDMA. The inter-turn gap information may be a ga p specified by the serving cell for the first time, or may be a feedback sent by the base station device in the serving cell according to the first feedback unit 52 or the second feedback unit 55. The gap information that is re-allocated for the terminal, the length of the gap specified by the terminal for the first time may be the default gap length of the system, or greater than or equal to the repetition period of the main information block in the neighboring area broadcast message.

The first determining unit 51 is configured to determine whether a main information block (MIB) in the neighboring area broadcast message can be read in the inter-turn gap segment received by the receiving unit 50.

[83] For example, the first determining unit 51 is configured to determine whether the inter-turn gap segment overlaps with a position where the main information block appears, and if yes, the first determining unit 51 It is judged that the main information block of the neighboring area can be read in the gap section. Otherwise, the first determining unit 51 determines that the main information block of the neighboring area cannot be read in the inter-turn gap gap.

[84] For example, when the serving cell and the neighboring cell are both in the LTE network, the first determining unit 51 is configured to determine that the 6 ms inter-segment occurs once every 40 ms of the inter-turn gap gap. Whether the lms appearing once every 10 ms of the neighboring cell frame with the MIB overlaps on the inter-axis, and if so, the first determining unit 51 determines that the MIB of the neighboring cell can be read, otherwise the first A judging unit 51 judges that the embarrassing unit The MIB of the neighboring area is not read by the inter-gap gap.

The inter-turn gap configured by a positional deviation information.

In another embodiment of the present invention, when the serving cell and the neighboring cell are both located in an LTE network, the first processing unit ₅₃ acquires the neighboring system information block in the primary information block. The frame number of the SIB1 (for example, the fifth subframe of the frame) and the repetition period information of the lms that the SIB1 appears once every 20 ms of the neighboring frame, and the inter-frame gap and the subframe deviation of the SIB1 can be obtained. When the serving cell is located in the L TE network, and the neighboring cell is located in the WCDMA network, and the serving cell and the neighboring cell are both located in the WCDMA network, the first processing unit 53 acquires the neighboring cell system in the primary information block. The location and repetition period of the information block SIB3, and the public land mobile network identifier (PLMN ID) information of the WCDMA network may also be acquired.

[88] The second determining unit 54 is configured to determine, according to the location and the repetition period of the system information block of the neighboring cell, whether the neighboring area broadcast message can be read in the inter-turn gap inter-segment The main information block in .

[89] For example, the second determining unit 54 is configured to determine whether the inter-turn gap segment overlaps with a position where the system information block appears, and if yes, the second determining unit 54 It is judged that the system information block can be read; otherwise, the second determining unit 54 determines that the system information block cannot be read. For example, when the acquired system information block is SIB1, the second determining unit 54 may determine whether 6 ms appearing once every 40 ms of the inter-turn gap and the lms of the SIB 1 appearing every 20 ms in the neighboring frame are The second judging unit 54 judges that the SIB of the neighboring area can be read, otherwise the second judging unit 54 judges that the inter-turn gap cannot be read. The SIB of the neighboring area. [90] a second feedback unit 55, configured to: when the determination result of the second determining unit 54 is negative, feed back the inter-turn gap and the second position deviation information of the system information block to the serving cell .

[91] For example, when the system information block is SIB1, the second position deviation information may be a frame deviation number and a subframe deviation number of the position where the inter-turn gap and the system information block appear; The system information block is SI B3 吋, and the second position deviation information may be a frame deviation number and a crevice deviation number of the position where the inter-turn gap and the system information block appear.

[92] The second processing unit 56 is configured to: when the determination result of the second determining unit 54 is 吋, the inter-turn gap segment received by the receiving unit ₅₀ , according to the first The location and the repetition period of the system information block acquired by the processing unit 53 are read, or the system information block of the neighboring cell is read, or when the determination result of the second determining unit ₅₄ is negative, the receiving unit 50 receives Reading the SIB in the neighboring area broadcast message according to the location and the repetition period of the obtained system information block, and acquiring the CGI of the neighboring area according to the SIB, The second inter-turn gap is a inter-turn gap configured by the serving cell according to the second position deviation information fed back by the second feedback unit 55.
