Operators can purchase only one set of equipment and support both 2G services. It can also support 3G services. It can also be used as a 2G single-mode device in the early stage. When it needs to provide 3G services in the later stage, it is directly used as multi-mode, which greatly reduces the equipment cost of operators, and therefore has received more and more attention.

The solution of the embodiment of the present invention is to configure the network interface information of the neighboring network element with the local network attribute information and the neighboring network element information of the local end before the multi-mode controller is connected to the neighboring network element, according to the neighboring network. The information of the network interface where the incoming message is sent by the element obtains the type of the incoming message, so that the incoming message is processed according to the type of the system, thereby implementing the connection between the multimode controller and the neighboring network element.

The embodiment of the present invention mainly uses a WCDMA (Wideband Code Division Multiple Access)/GSM (Global System for Mobile Communications) dual-mode controller as an example, and other modes of dual mode or multiple Modular combination, such as GSM, CDMA (Code Division Multiple Access), WCDMA, TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), and LTE (Long Term Evolution) Any combination of two or more of the new wireless communication systems that have been or have been subsequently evolved, such as TD-SCDMA/GSM dual mode, WCDMA/CDMA/GSM multimode, etc., at least two modes of access The seventh signaling network can be described with reference to the present invention. As shown in FIG. 1 , an embodiment of the present invention provides a method for interfacing a multi-mode controller with a neighboring network element, including:

Step S101: The multimode controller uses the local system attribute information and the adjacent network element information to be connected, and configures network interface information with the neighboring network element at the local end, and the multimode controller presents multiple system attributes on the local end;

The foregoing network interface information includes at least: a local signaling point of the multimode controller, local end attribute information, and a signaling point of the neighboring network element. At the transport network level, the "local signaling point + system identification" identifies the different standard attributes of the local end.

According to the identification method of the above-mentioned system attribute, when the multi-mode controller configures the network interface with other network elements, the transport layer information of each network interface is identified by at least the following elements (the order of the elements is in no particular order):

{OPC, System ID, DPC}, where:

OPC refers to the local signaling point of the multimode controller, and DPC refers to the signaling point of the adjacent network element.

For example: a multi-mode controller can be configured as a signaling point, a signaling point plus a different standard identification, can display a variety of different system attributes; at the same time, the multi-mode controller can also be configured as two signaling points, Two different signaling points plus different standard identifications can represent a variety of different system attributes.

Step S102: Receive an incoming message sent by the neighboring network element, determine the type of the incoming message according to the network interface information of the network interface where the incoming message is located, and perform processing on the corresponding standard service.

When an incoming message is sent to the multimode controller, the multimode controller first determines the network interface where the incoming message is located according to the signaling network layer, such as the signaling link where the incoming message is located, and then obtains the network interface according to the foregoing step S101. The interface identifier corresponding to the network interface in the network interface information can identify which type of the incoming message is based on the standard identifier in the interface identifier, and then process the incoming message according to the standard.

As shown in FIG. 2, in step S102, according to the network interface information of the network interface where the incoming message is located, The system type of the incoming message is determined, and the processing of the corresponding standard service includes:

Step S1021: Obtain signaling link information that carries an incoming message.

Step S1022: Determine a network interface where the signaling link is located.

The network interface is the network interface where the incoming message is located.

Step S1023: Read the configured network interface information according to the network interface, and obtain a system type of the incoming message.

Step S1024: Perform corresponding standard service processing according to the type of the incoming message.

There are several ways for the multi-mode controller to perform the corresponding standard service processing according to the type of the incoming message. The following several implementation modes are listed: The transmission signaling protocol layer such as MTP3B or MTP3 or M3UA can identify the incoming message. After the standard service, it is directly forwarded to the corresponding SCCP protocol module for subsequent processing. The standard identification identified by the MTP3B or MTP3 or M3UA transmission signaling protocol layer can also be directly brought to the SCCP protocol, by SCCP or SCCP. The protocol module performs the split processing; it may not identify the system type in the transmission signaling protocol layer such as MTP3B or MTP3 or M3UA, but directly transmits the information such as the signaling link to the upper SCCP protocol layer, and the SCCP protocol layer identifies which The standard business is then processed.

Since the core network (CN) network element has obvious single 2G or 3G system characteristics on the network interfaces such as A, Gb, Iu, IuPS, etc., when the docking method according to the present invention is implemented, the same BSC as the multimode controller is implemented. When the connection is similar, there is only one network interface, so the embodiment of the present invention will not be described in detail. In the embodiment, the multi-mode controller is connected to the adjacent controller network element as an example for detailed description.

The following is a process of connecting a signaling point and two signaling points to the RNC, BSC, and dual-mode controller at the local end by using a WCDMA/GSM dual-mode controller:

Example 1: The WCDMA/GSM dual-mode controller is connected to the RNC (the local end is two signaling points): As shown in Figure la, the adjacent network element of the dual-mode controller is the 3G RNC because the dual-mode controller has 2G, 3G attributes, so for the adjacent network element, the dual-mode controller is docked with There are two interfaces, Iur and Iur-g.

The two signaling points of the dual-mode controller are SPC1 (2G system signaling point) and SPC2 (3G system signaling point), and the corresponding system identification values are Net _2Q (2G standard identification) and Net _3Q (3G system identification). ), the neighboring network element RNC signaling point is SPC3, then the network interface information of the dual-mode controller side is as follows:

Configure an Iur-g interface, identified by at least {SPC1, Net _2G , SPC3}.

Configure an Iur interface, identified by at least {SPC2, Net _3G , SPC3}.

Then, when a UE originally controlled under the RNC detects that the 3G cell signal of the dual mode controller is strong, it initiates a soft addition process and attempts to add the cell to its own active set. The RNC sends a radio link add request message over the signaling link to the Iur interface between the dual mode controller. When the dual-mode controller receives the message sent from the RNC, it can determine that the network interface where the message is located is the Iur interface according to the transmission network layer information such as the signaling link where the message is located. According to the standard identifier Net _{3G in} the Iur network interface information {SPC2, Net _3G , SPC3 }, it can be known that the message is related to the 3G system, and the message is processed in the 3G system to add a response message to the RNC back to the correct wireless link.

The RNC receives the measurement report of the UE, and determines the handover to the GSM cell of the dual mode controller according to the cell capacity and load information of the neighboring cell. The RNC sends a relocation resource reservation request message to the dual mode controller through the signaling link of the Iur-g interface with the dual mode controller, requesting to reserve resources for the UE. When the dual-mode controller receives the message sent from the RNC, it can determine that the network interface where the message is located is the Iur-g interface according to the transmission network layer information such as the signaling link where the message is located. According to the standard identification of Net _{2G in} the Iur-g network interface information {SPC1, Net _2G , SPC3}, it can be known that the service is related to the 2G system, and the message is processed according to the 2G system, and the RNC returns a correct relocation resource reserve response. Message.

Example 2: The WCDMA/GSM dual-mode controller is connected to the BSC (the local end is two signaling points) As shown in Figure lb, when the adjacent network element of the dual-mode controller is a 2G BSC, the dual-mode controller has 2G. 3G attribute, so for the adjacent network element, the dual mode controller has an Iur-g interface.

The two signaling points of the dual-mode controller are SPC 1 and SPC2 respectively. The corresponding standard identification values are Net _2G (2G standard identification) and Net _3G (3G standard identification), and the adjacent BSC is SPC3, then the dual-mode controller side Configure the network interface information as follows:

Configure an Iur-g interface, identified by at least {SPC2, Net _3G , SPC3}.

The BSC receives the measurement report of the UE, and determines the handover to the 3G cell of the dual mode controller according to the cell capacity and load information of the neighboring cell. The BSC sends a relocation resource reservation request message to the dual mode controller through a signaling link of the lur-g interface with the dual mode controller, requesting to reserve resources for the UE. When the dual-mode controller receives the message sent from the BSC, it can determine that the network interface where the message is located is the lur-g interface according to the transmission network layer information such as the signaling link where the message is located. According to the system identification Net _{3G in} the lur-g network interface information {SPC2, Net _3G , SPC3}, it can be known that the service is related to the 3G system, and the above message is processed according to the 3G system, and the BSC is returned to the correct relocation resource to reserve a response. Message.

Example 3: The WCDMA/GSM dual-mode controller is connected to the dual-mode controller (the local end is two signaling points, and the opposite end is two signaling points):

As shown in Figure lc, when the adjacent network element of the dual mode controller is also a dual mode controller, since the two dual mode controllers have 2G and 3G system attributes, the dual mode controller has the same for the adjacent network element. One Iur interface and two lur-g interfaces have three interfaces. For the convenience of description, the local dual-mode controller is A, and the adjacent dual-mode controller is B.

The two signaling points of the dual-mode controller A are SPC1 (2G standard signaling point) and SPC2 (3G system signaling point), and the corresponding standard identification values are Net _2Q (2G standard identification) and Net _3Q (3G system). Identification), the adjacent dual-mode controller B also has two signaling points, namely SPC3 (2G standard signaling point) and SPC4 (3G standard signaling point), then the network interface information of the dual-mode controller A side is as follows:

Configure an Iur-g interface, at least identified by {SPC2, Net _3G , SPC3 }, for convenience of description. It is the Iur-g-1 interface;

Configure an Iur-g interface, which is identified by at least {SPC1, Net _2G , SPC4 }. For convenience of description, it is recorded as Iur-g-2 interface.

Configure an Iur interface, identified by at least {SPC2, Net _3G , SPC4 }.

The dual-mode controller B receives the measurement report of the UE under the GSM cell, and determines the handover to the 3G cell of the dual-mode controller A in combination with the cell capacity and load information of the neighboring cell. The dual mode controller B sends a relocation resource reservation request message to the dual mode controller through the signaling link of the Iur-g interface with A, requesting to reserve resources for the UE. When the dual-mode controller A receives the incoming message sent by the peer dual-mode controller B, it can determine that the network interface where the incoming message is located is Iur-g-1 according to the transmission network layer information such as the signaling link where the incoming message is located. According to the standard identification of Net _{3G in} the Iur-g-1 network interface information {SPC2, Net _3G , SPC3 }, it can be determined that the message is related to the 3G system, and processed according to the 3G system, and the correct weight is given to the dual-mode controller B. Locate the resource reservation response message.

The dual-mode controller B receives the measurement report of the UE under the 3G cell, and determines the handover to the GSM cell of the dual-mode controller A in combination with the cell capacity and load information of the neighboring cell. B sends a relocation resource reservation request message to the dual mode controller A through the signaling link of the Iur-g interface with A (the interface is denoted as Iur-g-2 at the A end), and the request is for the UE. Keep resources. When the dual-mode controller A receives the incoming message sent by the peer dual-mode controller B, it can determine that the network interface where the incoming message is located is Iur-g-2 according to the transmission network layer information such as the signaling link where the incoming message is located. According to the standard identification of Net _{2G in} the Iur-g-2 network interface information {SPC 1 , Net _2G , SPC4 }, it can be determined that the message is related to the 2G system, and processed according to the 2G system, and the dual-mode controller B is returned correctly. Relocate the resource reservation response message.

When a UE originally in the dual mode controller B 3G cell detects that the 3G cell signal of the dual mode controller A is strong, it initiates a soft addition process and attempts to add the cell to its own active set. B sends a radio link add message over the signaling link of the Iur interface with A. When the dual mode controller A receives the incoming message sent by the peer dual mode controller B, according to the letter of the incoming message Let the link and the like transmit the network layer information, and determine that the network interface where the incoming message is located is lur, according to the system identifier Net _3G in the lur network interface information {SPC2, Net _3G , SPC4 }, it can be determined that the message is related to the 3G system, The 3G system processes and adds a response message to the dual-mode controller B back to the correct wireless link. Of course, it is also possible to directly process the network interface information and directly process it according to the 3G system, because the lur interface can only serve as a docking network interface between the 3G and 3G standard network elements.

Embodiment 4: The dual-mode controller is connected to the dual-mode controller (the local controller is two signaling points, and the opposite end is a signaling point)

As shown in Figure Id, when the adjacent network element of the dual mode controller is also a dual mode controller, since both dual mode controllers have 2G and 3G attributes, the dual mode controller has I with the adjacent network element. A lur interface and two Iur-g interfaces have three interfaces. For convenience of description, the local dual-mode controller is A, and the adjacent dual-mode controller is B.

The two signaling points of the dual-mode controller are SPC1 (2G standard signaling point) and SPC2 (3G system signaling point), and the corresponding system identification values are Net _2Q (2G standard identification) and Net _3Q (3G system identification). ), the adjacent dual-mode controller has a signaling point SPC3, and the network interface information of the dual-mode controller side is as follows:

Configure an Iur-g interface, which is identified by at least {SPC1, Net _2G , and SPC3}. The local end is a 2G attribute, and the neighboring station is a 3G attribute. For convenience of description, it is recorded as an Iur-g-1 interface.

Configure an Iur-g interface, which is identified by at least {SPC2, Net _3G , and SPC3}. The local end is a 3G attribute, and the neighboring station is a 2G attribute. For the convenience of description, it is recorded as an Iur-g-2 interface.

Configure a lur interface, at least identified by {SPC2, Net _3G , SPC3}.

In this embodiment, the source signaling point (SPC2) and the target signaling point (SPC3) of the two network interfaces of Iur-g-2 and lur are identical, but the dual-mode controller B transmits the message due to the target cell. Differently, the network interface for sending messages is different, so the messages received by the dual-mode controller A can be completely distinguished by different network interfaces.

The subsequent processing process is the same as that in the foregoing Embodiment 3, that is, the signaling chain is obtained according to the incoming message. The corresponding network interface of the road information obtains the service attribute of the incoming message according to the interface identifier corresponding to the network interface, and performs subsequent processing according to the corresponding system to complete the connection between the dual mode controller A and the dual mode controller B. Embodiment 5: The dual-mode controller is connected to the RNC (the local end is a signaling point): As shown in FIG. 38, when the adjacent network element of the dual-mode controller is a 3G RNC, because the dual-mode controller has 2G, The 3G attribute, therefore, for the adjacent network element, the multimode controller has two interfaces, Iur and Iur-g, when docked with it.

The dual-mode controller signaling point is SPC1, and the corresponding system identification values are Net _2Q (2G standard identification) and Net _3G (3G standard identification), and the adjacent RNC signaling point is SPC3, then the dual-mode controller side configures the network interface. The message is below:

Configure an Iur-g interface, at least identified by {SPC 1 , Net _2G , SPC3 };

Configure an Iur interface, identified by at least {SPC1, Net _3G , SPC3}.

In this embodiment, the source signaling point (SPC1) and the target signaling point (SPC3) of the two network interfaces of Iur-g and Iur are identical, but when the transmitting network element RNC sends a message, because the target cell is different, The network interface for sending messages is different, so the message received by the dual-mode controller can completely distinguish whether it is Iur or Iur-g.

Refer to Embodiment 1 for the specific message processing procedure.

Embodiment 6: The dual-mode controller is connected to the BSC (the local end is a signaling point):

As shown in Figure If the adjacent network element of the dual mode controller is a 2G BSC, since the dual mode controller has 2G and 3G attributes, the dual mode controller has an Iur-g interface for the adjacent network element. .

The dual-mode controller signaling point is SPC 1 , and the corresponding system identification values are Net _2Q (2G standard identification) and Net _3G (3G standard identification), and the adjacent BSC signaling point is SPC3, then the dual-mode controller side configures the network. The interface information is as follows:

Configure an Iur-g interface, which is identified by at least {SPC1, Net _3G , SPC3}. Refer to Embodiment 2 for the specific message processing procedure.

Embodiment 7: The dual-mode controller is connected to the dual-mode controller (the local controller is a signaling point, and the opposite end is a signaling point):

As shown in FIG. 1g, when the adjacent network element of the dual mode controller is also a dual mode controller, since the two dual mode controllers have 2G and 3G attributes, the dual mode controller has one for the adjacent network element. The Iur interface and the two Iur-g interfaces have three interfaces. For the convenience of description, the local dual-mode controller is A, and the adjacent dual-mode controller is B.

The dual-mode controller A signaling point is SPC1, and the corresponding system identification values are Net _2Q (2G standard identification) and Net _3G (3G standard identification), and the adjacent dual-mode controller B signaling point is SPC3, then dual-mode control The network side configuration information on the device side is as follows:

Configure an Iur-g interface, which is identified by at least {SPC1, Net _3G , and SPC3}. The local end is a 3G attribute, and the neighboring station is a 2G attribute. For convenience of description, it is recorded as an Iur-g-2 interface.

Configure an Iur interface, identified by at least {SPC1, Net _3G , SPC3}.

After that, the dual-mode controller B receives the measurement report of the UE that is in the 3G cell, and determines the handover to the GSM cell of the dual-mode controller A in combination with the cell capacity and load information of the neighboring cell. B sends a relocation resource reservation request message to the dual mode controller A through the signaling link of the Iur-g interface with A (the interface is denoted as Iur-g-1 at the A end), and the request is for the UE. Keep resources. When the dual-mode controller A receives the incoming message sent by the peer dual-mode controller B, it can determine that the network interface where the incoming message is located is Iur-g-1 according to the transmission network layer information such as the signaling link where the incoming message is located. According to the standard identification of Net _{2G in} the Iur-g-1 network interface information {SPC1, Net _2G , SPC3 }, it can be determined that the message is related to the 2G system, and processed according to the 2G system, and the correct weight is given to the dual-mode controller B.

The area capacity and load information is determined to be switched to the 3G cell of the dual mode controller A. The dual mode controller B sends a relocation resource reservation request message to the dual mode controller through the signaling link of the Iur-g interface with A, requesting to reserve resources for the UE. When the dual-mode controller A receives the incoming message sent by the peer dual-mode controller B, it can determine that the network interface where the incoming message is located is Iur-g-2 according to the transmission network layer information such as the signaling link where the incoming message is located. According to the Iur-g-2 network interface information {SPC1, Net _3G , SPC3 }, the standard identification Net _3G can be determined that the message is related to the 3G system, and processed according to the 3G system, and the dual-mode controller B is returned to the correct weight. Locate the resource reservation response message.

When a UE originally in the dual mode controller B 3G cell detects that the 3G cell signal of the dual mode controller A is strong, it initiates a soft addition process and attempts to add the cell to its own active set. B sends a radio link add request message over the signaling link of the Iur interface with A. . When the dual-mode controller A receives the incoming message sent by the peer dual-mode controller B, according to the transmission network layer information such as the signaling link where the incoming message is located, it can be determined that the network interface where the incoming message is located is Iur, according to the present Iur The network interface information {SPC1, Net _3G , SPC3 } identifies the Net _3G in the system, and can determine that the message is related to the 3G system, and processes it according to the 3G system, and returns a response message to the correct wireless link to the dual-mode controller B.

(2G standard signaling point) and SPC4 (3G standard signaling point), then dual mode control The network side configuration information on the device side is as follows:
