Description

5 001137 Method and switching method for delivering a network number to a terminal in a communication system

The present invention relates to the field of mobile communications, and more particularly to a method for transmitting a network number to a terminal in a communication system, and a method for switching using the delivered network number. Background of the invention

In a mobile communication system, each carrier network has a unique corresponding network number.

(MNC), the MNC is carried in a system message sent to the terminal, after receiving the system message, the terminal according to the MNC in the system message, and the MNC stored in the terminal or in the user identification module (SIM) card Corresponding relationship between the network provider name (SPN), determining the corresponding SPN, and displaying the SPN to the user to increase the user's trust in the selected contracting operator.

In the prior art, only one MNC corresponding to the carrier network exists in an operator network, and the system message delivered by the network can only include the MNC, because the terminal displays the SPN according to the MNC in the received system message, Only the SPN of the operator can be displayed on all terminals accessing the carrier network.

When roaming technology is used in the same country or region to solve the coverage problem and provide services for users, after a terminal roams from the contracted carrier network to the non-contracted carrier network, the terminal displays the non-signed according to the received system message. The operator's SPN, which reduces the end user's trust to its contracted operators, and also reduces the operator's attractiveness to the contracted users.

For an operator, if you want to display the SPN of the carrier on its own subscriber terminal, you must conduct a network-wide coverage of all the areas where the subscriber terminal is located. Coverage can be achieved, which greatly increases the equipment investment of operators and increases the cost. In addition, since the contracting terminal of other domestic operators and the foreign terminal roam into the carrier network, there is no difference in the roaming identity assigned to the carrier network in the carrier network, so the operator cannot distinguish the terminal user roaming from abroad. And end users roaming from other carrier networks in the country. Summary of the invention

FIG. 3 is a general flowchart of a handover method according to the present invention. Mode for carrying out the invention

In order to make the objects, technical solutions and advantages of the present invention more comprehensible, the present invention will be further described in detail with reference to the accompanying drawings.

The main idea of the present invention is that a plurality of network numbers are configured by a cell in a base station controller, and each network number is configured to at least one cell, so that a network number belonging to different operators is delivered to the terminal in an operator network, and The handover of the terminal between cells of the same or different network numbers is implemented.

The invention can be applied to GSM, CDMA or WCDMA, CDMA2000, In a 3G mobile communication system such as TD-SCDMA, when used in GSM, the base station controller is a BSC; and when applied in a WCDMA system, the base station controller is a radio network controller (RNC).

The present invention will be described in detail below by taking the application of the present invention in the GSM system as an example.

In the first embodiment of the method for transmitting a network number to a terminal in a communication system, a plurality of network numbers are configured in a BSC according to a cell, that is, cells corresponding to different MNCs are configured, so that each network number corresponds to at least one Community. Specifically, the coverage of the original operator coverage area may be increased by adding a new cell or adding a base station in the communication system, and then setting a cell global for the cell in the newly added cell or the newly added base station. When identifying (CGI), set the MNC to be the MNC of the other carriers mentioned above. Other operators here can be one or more than one.

The above-mentioned method for adding a new base station can be applied to the carrier integration. For example, adding another operator's base station to the original one carrier's network without adding network devices such as BSC and MSC, only through the BSC The cell configuration in the newly added base station corresponds to the MNC of the newly added operator, and the coverage of the original operator with only one operator coverage area is realized. In addition, the base station belonging to the third operator can be similarly added. To realize the coverage of the three operators with only one operator coverage area, thus greatly reducing the equipment cost of building the network.

In this embodiment, when the base station sends a system message including the MNC in the cell, the MNC corresponding to the CGI of the cell is used as the MNC in the system message, and the system message is sent to the terminal in the cell.

After receiving the system message including the MNC, the terminal displays the SPN to the end user according to the corresponding relationship between the MNC and the pre-configured MNC and SPN in the terminal.

Other operators mentioned in this embodiment refer to other operators in the country, for In the present embodiment, the terminal user roaming abroad still adopts the prior art method, that is, the access of the foreign terminal user is realized by the roaming protocol, that is, the roaming identifier is allocated to the foreign terminal roaming to the network, thereby The roaming identity identifies the terminal that is roaming from abroad. In this way, the operator can distinguish between the end users roaming from abroad and the contracted end users of other domestic carrier networks in the carrier network, so as to implement statistics for different end users and adopt different charging methods.

The foregoing is a description of the first embodiment of the method for sending a network number to a terminal in a communication system. In this embodiment, a CGI including other operator MNCs is set for a part of cells in an operator network, and the base station is in a cell. When the system message is sent, the MNC in the cell CGI is carried in the system message and sent to the terminal in the cell, so that the MNC belonging to different carrier networks is sent to the terminal within one carrier network.

In the GSM system, the MSC may carry the MNC information in the signaling message exchanged with the BSC. In this case, the authenticity of the MNC information in the signaling message exchanged between the MSC and the BSC needs to be guaranteed. Therefore, the second embodiment and the third embodiment of the method for delivering a network number to a terminal in a communication system are proposed, which will be respectively described below.

In the second embodiment of the method for transmitting a network number to a terminal in a communication system, on the basis of the first embodiment, it is also required to be configured in the MSC according to the cells corresponding to different MNCs configured in the BSC. Corresponding to the cells of different MNC numbers, the same cell in the MSC corresponding to the same cell in the BSC is used. With the above configuration, when the message is exchanged, the same cell corresponding to the same cell in the signaling message exchanged between the MSC and the BSC is guaranteed.

Referring to FIG. 1 , an example of this embodiment is shown. In FIG. 1 , MNCs 00 and 01 belonging to two operators are configured in the MSC 101, and 460 in the figure is an MCC; correspondingly, two BSCs are also configured in the BSC 102. Operators of MNC, 00 and 01, due to MSC The MNC configured with the BSC is the same, so there is no need to perform MNC conversion in the message of interaction between the two. In addition, after the BSC sets the corresponding MNC in the cell CGI, the BTS can send the message from the BSC to the terminal according to the received message on the cell corresponding to the MNC. System message, it can be seen from the figure that the MNC corresponding to the cell 0 and the cell 2 is 00, and the MNC corresponding to the cell 1 and the cell 3 is 01, and when the system message including the MNC is delivered to the terminal on the cell 0 and the cell 2, The MNC included in the message is 00. When the system message including the MNC is sent in the cell 1 and the cell 3, the MNC included in the message is 01. For example, the BSC sends a message including the MNC to the BTS to the BTS 1031. After receiving the message, the BTS 1031 recognizes that the MNC is included and is 00. Then, the system sends a system including the MNC 00 to the terminal according to the message on the cell 0. Message: After the terminal 104 accessing the cell 0 receives the system message through the Um interface, the MNC can display the corresponding SPN according to 00.

In addition, in order to realize that the MNC in the system message sent to the terminal is the MNC corresponding to the operator's network, the MSC and the HLR may also set corresponding user data for the terminal according to the contracting operator MNC to ensure that the terminal only The MNC that is carried in the system message that is sent to the terminal is also the MNC that is corresponding to the terminal subscription operator. The setting of the specific user data may be: setting the corresponding MNC for the terminal in the International Mobile Subscriber Identity Global Identity (IMSS GT) table and the GT table of the MSC, and routing in the HLR. In the address information, the corresponding MNC is set for the terminal.

In the third embodiment of the method for sending a network number to a terminal in a communication system, there may be only one MNC in the MSC, that is, for even in the BSC, the MNC in the CGI is not the network operator MNC. Cell, MNC in CGI in MSC It can still be the MNC of the carrier network.

In order to solve the problem that the MNC is inconsistent in the signaling message of the interaction between the MSC and the BSC, in this embodiment, based on the first embodiment, the MNC in the signaling message is converted on the A interface between the BSC and the MSC, below Detailed instructions are given.

In the uplink direction, before the BSC sends a message including the MNC to the MSC, it determines whether the MNC is an MNC supported by the MSC, and if so, directly sends the message to the MSC; otherwise, the MNC supported by the MSC, that is, the BSC belongs to The MNC corresponding to the carrier network replaces the original MNC in the message, and then sends the message to the MSC. In this way, for the MSC, the MNC in the received uplink message is the MNC supported by the MSC, and no system error occurs.

In the downlink direction, after receiving the signaling message including the cell information from the MSC, the BSC determines the cell in the corresponding base station controller according to the non-MNC information in the cell information, and then replaces the MNC corresponding to the determined cell. After receiving the MNC in the signaling message from the MSC, the MCU sends the message to the base station corresponding to the determined cell. After receiving the message sent by the BSC, the base station sends the corresponding MNC to the terminal on the corresponding cell. Message.

The BSC may perform the indexing according to the cell information in the signaling message sent by the MSC according to the cell information in the message sent by the MSC according to the cell information in the message sent by the MSC, that is, the BSC first determines the index according to the cell information in the signaling message sent by the MSC. The cell information format is then determined according to the index format to the corresponding cell in itself.

The LAC+CI of the same cell in the MSC and the BSC is identical. Therefore, as shown in Table 1, when the cell information included in the message sent by the MSC is CGI, the index format corresponding to the CGI is not included. The LAC+CI of the MNC, the BSC determines the corresponding cell according to the LAC+CI in the CGI information. When the cell information included in the message sent by the MSC is the LAC, the LAC is not involved in the LAC. The corresponding index format is still LAC. Similarly, when the cell information in the signaling message sent by the MSC is LAC + CI, the corresponding index format is still LAC+CI; when the cell information sent by the MSC is the CI information, the cell information is CI. The corresponding index format is still CI; when the cell information in the signaling message sent by the MSC is the location area identifier (LAI), since the LAI includes the MCC, the MNC, and the LAC, the corresponding index format is not included. MNC's LAC.

Table 1

As shown in Figure 2, it is assumed that MNC-A and MNC-B are set in the BSC, and the MSC only supports MNC-A. As shown in the figure, in the uplink direction, when the signaling message carries the MNC-A, the message is directly forwarded on the A interface; and when the signaling message carries the MNC-B, the BSC converts the MNC-B into the MNC- After A is sent to the MSC through the A interface. In the downlink direction, for the signaling messages carrying the MNC-A, LAC0, and CIO, the BSC determines that the MNC corresponding to the cell in the cell is still the MNC-A according to the LAC0 and the CI0, so in the signaling message sent to the BTS through the Abis interface. The MNC is still MNC-A; for the signaling messages carrying MNC-B, LAC1, and CI1, the BSC determines that the MNC corresponding to the cell in itself is M CB according to LAC1 and CI1, then converts the MNC-A into MNC-B, and then The message is sent to the corresponding BTS through the Abis interface.

In this embodiment, in the message exchanged between the MSC and the BSC, the message that may carry the cell information includes a Base Station Sub-system Management Application Part (BSSMAP) message and a direct transmission application part (Direct Translation Application) Part, DTAP ) message. The above is a description of a specific embodiment of a method for transmitting a network number to a terminal in a communication system according to the present invention.

In order to save network resources, respectively, switching between two MNC cells that are physically covered, between adjacent MNC cells, and between adjacent MNC cells, the present invention also provides various flexible handovers. method.

As shown in FIG. 3, the overall process of the handover method of the present invention includes the following steps: Step 301: Configure a plurality of network numbers in a BSC according to a cell, so that each network number corresponds to at least one cell.

The specific implementation of this step may be the same as the method for configuring a cell by MNC in the first embodiment of the method for delivering the MNC to the terminal in the communication system.

Step 302: The BSC generates, for the terminal, a candidate cell queue that includes different MNC cells, and adjusts the queue according to network characteristics of the cells in the queue.

After a plurality of network numbers are configured according to the cell in the BSC, when the neighboring cell is configured for the cell, the MNC factor is not considered, and the configuration is performed according to the normal situation. In the candidate cell queue generated by the BSC for the terminal, the terminal serving cell is included. Corresponding to cells of the same and different MNCs. Here, the cell in the candidate cell queue corresponding to the same serving cell as the MNC includes the serving cell and the neighboring cell corresponding to the same MNC as the serving cell.

In addition, in this step, the method for specifically generating the candidate cell queue may adopt a method provided by a standard protocol, for example, according to! The ^ and K criteria generate a candidate cell queue; and adjusting the queue according to the network characteristics of the cell means adjusting the queue according to whether the cell in the queue is the same as the serving cell, or whether it is the same as the serving cell, the receiving level, and the like. After adjustment, the cells in the queue of candidate cells are sorted according to the quality of service, that is, the best service shield is ranked first, and the cells with poor service quality are ranked later. The specific quality of service can be integrated with level, quality, cell level, load, and whether it is the same as the MSC, whether it is the same as the BSC. Step 303: Perform a handover according to the adjusted queue in step 302.

In this step, the specific handover decision triggering method may use any one of the prior art handover decision triggering methods, such as normal signaling voice channel switching, direct retry, handover candidate query, and OMC background initiated forced handover. Wait.

The specific implementation manner of the handover method implemented according to the flow in FIG. 3 is referred to as normal handover in this specification, and is applicable to completely sharing resources corresponding to different MNCs in the operator network regardless of charging factors, and only considers The user provides the best quality cell, ie in the case of quality priority.

In addition, in the handover method of the present invention, in step 302, after adjusting the queue according to the network feature, the queue is adjusted according to the MNC of the cell in the queue. Different adjustment methods correspond to the specific implementation methods of different switching methods.

1. Only allow switching between cells in the same MNC

In this mode, the candidate cell queue is adjusted according to the MNC to: Delete the cell in the candidate cell queue that is different from the serving cell by the MNC, and other steps are the same as in FIG. 3 . After deleting the cells of different MNCs corresponding to the serving cell, all the remaining cells in the candidate cell queue are the same MNCs as the serving cell, so when the terminal performs handover, it can only switch to the same MNC as the serving cell. Community. After the deletion candidate serving cell and a cell queue corresponding to a cell of a different MNC, the remainder of the order to the original order in the cell of the same cell, i.e. the amount of good and services shield arranged forward ₀

This method can be applied to resources that do not share between different MNCs, and considering the charging factor, that is, the cost priority, the terminal can only switch to the same MNC cell corresponding to the serving cell. 2. Priority switching with the MNC cell

In this mode, the candidate cell queue is adjusted according to the MNC to: All cells corresponding to the same MNC are arranged in front of all cells of the MNC corresponding to the serving cell. In this manner, the cell in the original candidate cell queue is actually divided into two parts: a cell corresponding to the same MNC as the serving cell, called an A queue; and a cell corresponding to the serving cell with a different MNC, called a B queue. Within the A queue and the B queue, the order between any two cells is the same as the order of the two cells in the original candidate cell queue. After the candidate cell queue is adjusted according to the MNC number, the candidate cell queue is actually the A queue + B queue, which ensures that when the terminal performs handover according to the candidate cell queue, the terminal preferentially switches to the same MNC corresponding to the serving cell. . In this mode, the cell corresponding to the same MNC as the monthly cell, that is, the cell in the A queue, is preferentially switched to the cell if the receiving level of the cell is higher than the minimum downlink power of the handover candidate cell corresponding to the cell. In the first case.

3. Better cell priority switching with MNC

In this manner, the candidate cell queue is adjusted according to the MNC to: the same MNC as the serving cell, and the cells whose reception level is higher than the inter-layer handover threshold are arranged before other cells in the candidate cell queue. The specific determination method of whether the receiving level is higher than the inter-layer switching threshold may be: for the serving cell, determining whether the receiving level of the cell is higher than the inter-layer handover threshold corresponding to the cell, and subtracting the inter-layer handover hysteresis corresponding to the cell. For the neighboring cell, it is determined whether the receiving level of the cell is higher than the inter-layer handover threshold corresponding to the cell plus the inter-layer handover hysteresis corresponding to the cell. Suppose that the cell with the same MNC as the serving cell and the receiving level is higher than the inter-layer switching threshold constitutes the A queue. The cells in the candidate cell queue except the cell in the A queue form the B queue, and then in the A queue and the B queue. , The sequence between each two cells is consistent with the sequence in the original candidate cell queue, and the adjusted candidate cell queue becomes the A queue + B queue. In the case of cost priority or quality priority.

4, different MNC better cell priority switching

In this manner, the candidate cell queue is adjusted according to the MNC to: the MNC corresponding to the serving cell is different, and the cells whose receiving level is higher than the inter-layer handover threshold are arranged before other cells in the candidate cell queue. If the cell corresponding to the different MNCs of the serving cell is a neighboring cell, in this manner, when determining whether the cell is higher than the inter-layer handover threshold, it is determined whether the receiving level of the different MNC cell corresponding to the serving cell is higher than the corresponding cell. The inter-layer handover threshold is added to the inter-layer handover hysteresis corresponding to the cell. It is assumed that the MNC corresponding to the serving cell has a different MNC, and the cell whose receiving level is higher than the inter-layer switching threshold constitutes the A-queue. If the cell in the candidate cell queue except the cell in the A-queue constitutes the B-queue, it is inside the A-queue and the B-queue. The sequence between the two cells is consistent with the sequence in the original candidate cell queue, and the adjusted candidate cell queue becomes the A queue + B queue.

This method can be applied to allow sharing between resources corresponding to different MNCs, and there is a case where quality is prioritized.

5, different MNC cell priority switching

In this mode, the candidate cell queue is adjusted according to the MNC to: all cells that are different from the serving cell corresponding to the MNC are arranged before all cells of the same MNC as the serving cell. In this manner, the cell in the original candidate cell queue is actually divided into two parts: It is assumed that the cell corresponding to the MNC corresponding to the serving cell is called the A queue; the cell corresponding to the same MNC as the serving cell is called B. Queue; Within the A queue and the B queue, the order between any two cells is the same as the order of the two cells in the original candidate cell queue. After adjusting the candidate cell queue according to the MNC number, The selected cell queue is actually the above A queue + B queue, so that the terminal is preferentially switched to the cell corresponding to the different MNCs corresponding to the serving cell when the terminal switches. In this mode, the cell corresponding to the MNC corresponding to the serving cell, that is, the cell in the A queue, is preferentially switched to the cell as long as the receiving level of the cell is higher than the minimum downlink power of the handover candidate cell corresponding to the cell.

6, only allow different MNC cell switching

In this mode, the candidate cell queue is adjusted according to the MNC to: Delete the cell in the candidate cell queue that corresponds to the same MNC as the serving cell. After deleting the cell with the same MNC as the serving cell, the remaining cells in the candidate cell queue are all cells of different MNCs corresponding to the serving cell, so when the terminal performs handover, it can only switch to a different MNC corresponding to the serving cell. Community. After deleting the cell of the same MNC corresponding to the serving cell in the candidate cell queue, the order of the remaining cells is the same as that of the original cells, that is, the quality of service is ranked first.

This method can be applied in the case of sharing between resources corresponding to different MNCs. In the handover method of the present invention, a handover identifier may be set in the BSC, and different values of the identifiers respectively correspond to all of the above, or partially different handover implementation manners. Then, in step 302 shown in FIG. 3, after performing network feature adjustment on the candidate cell queue, the BSC first reads the handover identifier, and then adjusts or adjusts the candidate cell queue according to the handover specific implementation manner corresponding to the handover identifier. Then step 303 is performed.

The above is a description of specific embodiments of the invention, but the method according to the invention may be suitably modified in a particular implementation to suit the particular needs of the particular situation. Therefore, it is to be understood that the specific embodiments of the present invention are intended to be illustrative only and not to limit the scope of the invention.

The method according to claim 9, wherein the handover identifier is set in advance in the base station controller, and each value of the handover identifier corresponds to a network number corresponding to the cell in the queue of the candidate cell And the method for adjusting the candidate cell queue; before the step a1, the method further includes: the base station controller reading the handover identifier, determining, according to the handover identifier, the candidate cell queue according to the network number corresponding to the cell in the candidate cell queue The method of adjustment is then performed according to the determined adjustment method.

The method according to claim 9 or 10, wherein the method for adjusting the candidate cell queue according to the network number corresponding to the cell in the candidate cell queue is:

Or: deleting all cells in the queue that have the same network number as the serving cell, and only allowing the terminal to switch between cells corresponding to different network numbers;

Or: all cells in the queue corresponding to the same network number as the serving cell are arranged in front of all cells corresponding to different network numbers of the serving cell, so that the terminal preferentially switches between cells corresponding to the same network number;

Or: all the cells in the queue corresponding to the different cell numbers of the serving cell are arranged in front of all the cells corresponding to the same network number as the serving cell, and the terminal is preferentially switched between the cells corresponding to the different network numbers;

Or: the same network number corresponding to the serving cell in the queue, and the receiving level is higher than The cells of the inter-layer handover threshold are arranged in the queue before the other cells in the queue, so that the terminal preferentially switches to the cell with the same network number as the serving cell and the receiving level is higher than the inter-layer handover threshold; or: The serving cell corresponds to a different network number, and the cell whose receiving level is higher than the inter-layer switching threshold is arranged in front of other cells in the queue, so that the terminal preferentially switches to a different network number corresponding to the serving cell, and the receiving level is higher than the inter-layer switching. Threshold cell.
