Method, device and system for global cell identification processing. The present application claims a Chinese patent filed on September 27, 2009, with the application number 200910196862.5, entitled "A Method, Apparatus and System for Global Cell Identification Processing" Priority of the application, the entire contents of which are incorporated herein by reference. Technical field

The present invention relates to the field of communications technologies, and in particular, to a method, apparatus, and system for global cell identity processing.

Background technique

In the Universal Mobile Telecommunications System (

In a UMTS) radio access network, each cell has a cell ID (Cell ID).

In the process of the UE switching from the UMTS Access Point (AP) to other networks, such as the macro network, the UMTS AP needs to have the plug-and-play feature. To meet this requirement, the UMTS AP supports the automatic network rule function. The built-in third-generation mobile communication/second-generation mobile communication receiver performs macro cell neighboring area configuration by automatic cell search in User Equipment (UE) mode, and the radio network controller (Radio Network Controller) is searched. The system message sent by the RNC is obtained by acquiring the macro cell Cell ID (ie, the target cell Cell ID) of the neighboring cell of the AP cell and other information. The above system message is sent by the RNC through the interface between the user equipment and the universal terrestrial radio access network (Uu interface).

Since the Cell ID contains information about the geographical location of the cell, the Cell ID-based positioning method is often used to locate the terminal in the mobile positioning technology. The Cell ID based positioning method determines the location of the terminal based on the Cell ID of the cell in which the mobile station is located. Since the Cell ID positioning technology does not require the positioning measurement of the mobile station, and the positioning information transmission of the wireless interface is small, the positioning response time is short, which is a widely used mobile positioning technology.

However, in the prior art, in the process of transmitting the €611 10 through the 1111 interface, if an illegal third party obtains the correspondence between the Cell ID and the geographical location of the cell by using the Cell ID positioning technology, it is possible The Cell ID-based positioning service is illegally provided to the UE.

detailed description

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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. In order to prevent the illegal third party from using the Cell ID locating technology to obtain the correspondence between the Cell ID and the geographic location of the cell, the RNC can send the dynamic message through the system message in the Uu interface. The Cell ID parameter, which is a false value, is not equal to the actual Cell ID, and can also be changed periodically. In this way, an illegal third party cannot obtain the correspondence between the dynamic Cell ID and the real Cell lD, and the real geographical location information cannot be obtained.

First, the UE uses a static (ie, real) Cell ID to switch from the UMTS AP to the macro network as an example. As shown in FIG. 1, the flow chart of the UE switching from the UMTS access point (AP) to the macro network is shown. .

Step 101: Acquiring the cell ID of the macro cell; The UMTS access point (AP) needs to have a plug-and-play feature. To meet this requirement, the UMTS AP supports the automatic network rule function and can adopt the built-in third generation. The third generation mobile Telecommunication/Second Generation (3G/2G) receiver performs macro cell neighboring area configuration by automatic cell search in User Equipment (UE) mode. The system message sent by the radio network controller (RNC) acquires the macro cell Cell ID (ie, the target cell Cell ID), the RNC ID, and other information of the neighboring cell of the AP cell. The above system message is sent by the RNC through the interface between the user equipment and the universal terrestrial radio access network (User Equipment Universal Terrestrial Radio Access Network, Uu interface).

Step 102: Initiating the handover process; when the AP is powered on to perform automatic neighbor search or periodic automatic neighbor search, the UMTS AP sends the migration to the core network (Core Network, CN) via the access gateway (AG). The Relocation Required message is used to initiate the handover procedure. The Relocation Required message carries the acquired macro cell Cell ID and the RNC ID of the macro cell (ie, the target RNC ID). Target RNC.

Step 104: The CN sends a Relocation Request message to the target RNC, and carries the macro cell Cell ID (ie, the target cell Cell ID) to perform a subsequent handover process.

In the foregoing embodiment, in step 101, the real Cell ID sent by the RNC to the AP through the Uu interface may be intercepted. If the RNC sends a dynamic Cell ID to the AP through the Uu interface, even if it is intercepted, the illegal third party Still unable to obtain Cell ID and cell geographic location using Cell ID positioning technology Correspondence relationship. The manner in which the dynamic cell identity is used for handover will be specifically described below.

The first embodiment of the present invention provides a method for processing global cell identifiers. As shown in FIG. 2, the method may include the following steps:

Step 201: Send a global cell identifier to the AP, where the global cell identifier includes a dynamic cell identifier and a real radio network controller identifier, so that the access point sends the global identifier of the real radio network controller identifier to the core network.

Step 202: Receive a migration request message sent by the core network. After receiving the global cell identifier sent by the access point, the migration request message is sent according to the real radio network controller identifier included in the global cell identifier.

The foregoing migration request message may include a dynamic cell identifier, and the method further includes: after the step 202, searching: corresponding to the dynamic cell identifier included in the received migration request message, according to the saved dynamic cell identifier and the real cell identifier. Real cell identity.

Certainly, the foregoing migration request message may also include a real cell identifier, where the real cell identifier may be used to search for a real cell identifier according to the dynamic cell identifier, or may be used by the AP to find the real entity according to the dynamic cell identifier. The cell identity is obtained. As for the implementation of the search, the RNC may send a correspondence between the dynamic cell identifier and the real cell identifier to the core network or the AP, and then the CN or the AP implements the conversion between the dynamic cell identifier and the real cell identifier. In this case, the migration request message is used. The embodiment of the present invention is not limited.

The executor of the foregoing solution may be an RNC. In the foregoing embodiment, the global cell identifier includes the real RNC ID. According to the original process, the global cell identifier includes the real RNC ID, and the core network may find the real RNC ID according to the real RNC ID. The target RNC, the CN initiates a handover procedure to the target RNC; the RNC may acquire the real cell identifier of the target cell according to the dynamic cell identifier, because the RNC saves the correspondence between the dynamic cell identifier and the real cell identifier; The UE can successfully initiate a handover from the Femto cell to the macro cell. The cell ID sent by the RNC to the AP through the air interface is the dynamic cell ID. The illegal third party cannot obtain the correspondence between the cell ID and the geographic location of the cell, thus improving information security.

Further, the sending the dynamic cell identifier may be: periodically sending a dynamic cell identifier periodically, and using a corresponding relationship between different dynamic cell identifiers and real cell identifiers in each period;

The foregoing, according to the correspondence between the dynamic cell identifier and the real cell identifier, the real cell identifier corresponding to the dynamic cell identifier included in the received migration request message may be: Corresponding relationship between the dynamic cell identifier of the period in which the cell identifier is located and the real cell identifier is used to search for the real cell identifier corresponding to the dynamic cell identifier included in the received migration request message.

In the foregoing implementation manner, changing the correspondence between the dynamic cell identifier and the real cell identifier can improve the security of the dynamic cell identifier. Of course, it is also possible to use the correspondence between the fixed dynamic cell identifier and the real cell identifier, which does not affect the implementation of the embodiment of the present invention. Embodiment 2 The embodiment of the present invention further provides another method for global cell identifier processing. As shown in FIG. 3, the following steps may be included:

Step 301: Receive and save a correspondence between a dynamic radio network controller identifier and a real radio network controller identifier;

The mapping between the dynamic wireless network controller identifier and the real wireless network controller identifier may be: mapping relationship between the dynamic wireless network controller identifier and the real wireless network controller identifier; or: dynamic wireless network controller identifier and real wireless The conversion key identified by the network controller; further, the correspondence between the dynamic cell identifier and the real cell identifier may also be received and saved. The foregoing correspondence may be a mapping relationship or a conversion key, which is not limited in the embodiment of the present invention.

Step 302: After receiving the dynamic global cell identifier, the dynamic global cell identifier includes a dynamic cell identifier and a dynamic radio network controller identifier, and the foregoing dynamic wireless is obtained by the correspondence between the dynamic radio network controller identifier and the real radio network controller identifier. The network controller identifies the corresponding real wireless network controller identifier;

If the correspondence between the dynamic cell identifier and the real cell identifier is received and saved, the real cell identifier corresponding to the dynamic cell identifier may be obtained by the corresponding relationship between the cell identifier and the real cell identifier.

Step 303: Send a global cell identifier including the identifier of the real radio network controller to the core network. If the real cell identifier is obtained in step 302, the global cell identifier including the real cell identifier may also be sent to the core network.

The executor of the foregoing embodiment may be an AP. The AP obtains the correspondence between the dynamic RNC ID and the real RNC ID. After receiving the dynamic RNC ID, the AP may obtain the real RNC ID according to the corresponding relationship, and the AP obtains the real After the RNC ID, the global cell ID including the dynamic cell ID and the real RNC ID may be sent to the CN, and the CN performs subsequent switching operations, and may also The dynamic Cell ID is also converted to the real Cell ID. In this case, the AP obtains the real global Cell ID, including the real Cell ID and RNC ID. The AP can perform subsequent operations according to the original method. Therefore, the dynamic cell identifier is used. At the same time, the UE can successfully initiate a handover from the Femto cell to the macro cell.

Specifically, the correspondence between the dynamic identifier and the real identifier may be: a mapping relationship between the dynamic identifier and the real identifier or a conversion key; the dynamic identifier is a dynamic cell identifier or a dynamic radio network controller identifier; and the real identifier is a real cell. Identification or real wireless network controller identity;

The real cell identifier corresponding to the dynamic cell identifier obtained by the correspondence between the dynamic cell identifier and the real cell identifier includes:

And finding a mapping relationship between the dynamic cell identifier and the real cell identifier to obtain a real cell identifier corresponding to the dynamic cell identifier;

The real wireless network controller identifier corresponding to the dynamic radio network controller identifier obtained by the correspondence between the dynamic radio network controller identifier and the real radio network controller identifier includes: searching the dynamic radio network controller identifier and the real wireless The mapping relationship of the network controller identifier is obtained by the real radio network controller identifier corresponding to the dynamic radio network controller identifier;

Or,

Decrypting the dynamic cell identifier by using the conversion key to obtain a real cell identifier; the correspondence between the dynamic radio network controller identifier and the real radio network controller identifier is obtained by the dynamic radio network controller identifier. The radio network controller identifier includes: decrypting the dynamic radio network controller identifier by using the conversion key to obtain a real radio network controller identifier.

The corresponding relationship between the dynamic cell identifier and the real cell identifier may be: receiving and storing the correspondence between the dynamic cell identifier periodically sent and the real cell identifier, and different dynamic cell identifiers and realities are used in each period. Correspondence relationship of cell identifiers;

The real cell identifier corresponding to the dynamic cell identifier obtained by the correspondence between the dynamic cell identifier and the real cell identifier may be: the dynamic cell identifier corresponding to the real cell identifier in the period in which the dynamic cell identifier is located, and the dynamic cell identifier corresponding to the dynamic cell identifier Real cell identity.

In addition, the correspondence between the dynamic wireless network controller and the real wireless network controller may also be Periodically issued, and the corresponding relationship adopted in each cycle is different. The specific implementation can be performed by referring to the implementation manner of the cell identifier.

In the foregoing implementation manner, changing the correspondence between the dynamic cell identifier and the real cell identifier can improve the security of the dynamic cell identifier. Of course, it is also possible to use the correspondence between the fixed dynamic cell identifier and the real cell identifier, which does not affect the implementation of the embodiment of the present invention. Embodiment 3 This embodiment further describes the solution of Embodiment 1. In this embodiment,

The global cell ID delivered by the RNC includes: Dynamic Cell ID and real RNC ID. The RNC ID of the macro network neighboring area that the AP searches for is real. The AP sends the global cell identifier to the CN, including the dynamic cell ID and the real RNC ID. The core network parses the RNC ID information, and the Cell ID is transparently transmitted on the core network. The handover information is sent to the correct target macro RNC according to the real RNC ID in the global Cell ID, and does not affect the handover of the AP to the macro network.

As shown in Figure 4, the specific processing flow is as follows:

Step 401: The macro RNC periodically generates a dynamic Cell ID of all the cells under it, and the RNC ID is its real RNC ID. The macro RNC saves the relationship between the dynamic Cell ID and the real Cell ID. The corresponding relationship can be used by the operator. The information query is performed on the query server by interacting with the macro network system. The dynamic cell ID of all cells in the RNC is sent by the system message update.

Step 402: When the AP is powered on to perform automatic neighbor search or perform periodic automatic neighbor search, the dynamic cell ID and the real RNC ID are obtained from the system message broadcast by the air interface macro RNC, and the macro cell neighboring area is configured by using this parameter. ;

Step 403: When a certain UE of the AP cell needs to perform handover to the macro network, the AP initiates a handover procedure, and brings the dynamic cell ID and the real RNC ID of the target macro RNC to the CN. The gateway (Access Gateway, AG) sends a Relocation Required message to the CN, initiates a handover procedure, and brings the dynamic Cell ID of the target macro RNC to the CN through a Relocation Required message;

Step 404: The message sent by the AP to the CN through the AG includes the real RNC ID, and the CN sends a message to the target RNC according to the RNC ID to continue the handover process. Specifically, the CN can send a handover request (Relocation Request) message to the correct target RNC according to the RNC ID;

Step 405: The macro RNC converts the dynamic Cell ID into a real Cell ID according to the mapping relationship between the dynamic Cell ID and the real Cell ID saved by the macro RNC. Specifically, the handover request may be: The dynamic Cell ID in the message is converted into a real Cell ID. The RNC finds the corresponding cell of the corresponding base station (NodeB) according to the real Cell ID, and establishes a Radio Link (RL) on the NodeB.

Step 406: The RNC sends a message to the CN to inform the core network that the target cell has completed the handover preparation. The specific message may be: sending a Relocation Request Ack message to inform the core network that the target cell has completed the handover preparation;

Step 407: Step 408: The CN sends a message to the Femto system (including the AP and the AG) to notify the AP that the user equipment (UE) can be triggered to be handed over. Specifically, the message may be sent by using a Relocation Command message. The AP can trigger the UE to switch.

Step 409: The AP initiates Radio Resource Control (R C ) and Radio Bearer (RB) reconfiguration (Reconfiguration) to the UE;

Step 410: After the UE completes the reconfiguration, the UE sends a message to the RNC to notify the RNS that the UE has completed the handover. Specifically, the UE may send an R C RB Reconfiguration Complete message to inform the RNC that the UE has completed the handover.

Step 411: The RNC sends a message to the CN to notify the CN that the target cell has completed the migration. Specifically, the message may be: sending a Relocation Complete message to notify the CN target cell that the migration has been completed. Step 412: Step 413: The core network sends a message to the Femto system. Inform the AP that the resource can be released; specifically, it can send an Iu release command (Release Command) to inform the AP that the resource can be released;

Step 414: The AP releases the resource.

Step 415, Step 416: The Femto system returns a message to the CN to inform the CN source cell that the Iu interface link is released. Specifically, the Iu release complete (Release Complete) message may be sent to inform the CN source cell that the Iu interface link is released. The entire switching process.

The dynamic global 'j, the RNC ID in the area identifier is the real RNC ID; according to the original process, the dynamic cell identifier reported by the AP includes the real RNC ID, and the core network can find the target RNC according to the real RNC ID. The target RNC sends the dynamic cell identifier to perform cell handover. The RNC can obtain the real cell identifier of the target cell according to the dynamic cell identifier, because the dynamic cell identifier and the real cell identifier are saved in the RNC. Therefore, when the dynamic cell identifier is used, The UE can successfully initiate a handover from the Femto cell to the macro cell. Because the Cell ID sent to the AP through the air interface is the dynamic Cell ID, the illegal third party cannot obtain the Cell ID and the geographic location of the cell. Correspondence, thereby improving information security. The fourth embodiment, the embodiment will use the dynamic cell ID and the real cell ID mapping relationship, and the dynamic RNC ID and the real RNC ID mapping relationship as an example. In this embodiment, the AP will dynamically generate the Cell ID and The RNC IDs are all converted to real. For convenience, we call the conversion of the dynamic global Cell ID to the real global Cell ID. As shown in Figure 5, the following steps are included:

Step 501: The macro RNC periodically generates a dynamic global Cell ID of all cells under it. The dynamic global Cell ID of a cell that H does not generate is Paral;

Step 502: After the dynamic global Cell ID is generated, the macro RNC sends the mapping relationship between the dynamic global cell ID and the real global cell ID to the RNC network management system. To facilitate the processing of the RNC, all macro RNCs can set a unified dynamic global cell ID. Generation cycle and time point). Further, in order to ensure that the macro RNC obtains the latest mapping relationship information before updating the dynamic global cell ID in the system message, the macro RNC may set a delay timer t1 after the dynamic global Cell ID of a certain period is generated. After the delay is tl, the RNC updates the dynamic global Cell ID information of the period in the air interface system message.

Step 503: After receiving the mapping relationship reported by each RNC, the RNC network management merges the mapping relationship information of all the RNCs into a file and transmits the information to the AP system (AP network management system and AP) through the interface with the AP network management system.

Step 504: The AP network management receives the mapping relationship between the dynamic global cell ID of the macro RNC and the real global cell ID, and sends it to all APs managed by the AP.

Step 505: The AP updates the mapping relationship between the dynamic global cell ID and the real global cell ID.

Step 506: The macro RNC updates the dynamic global Cell ID information of all the cells in the air interface system message, including Paral; the air interface system message can be received by the AP, the UE, and the like that receive the message in the air interface.

Step 507: When the AP performs an automatic neighbor search, the dynamic global Cell ID Paral is obtained from the air interface. At this time, the AP finds the real global Cell ID corresponding to Paral from the mapping relationship between the dynamic global cell ID and the real global cell ID, and configures the macro cell neighbor with the real global Cell lD. The subsequent AP to macro cell handover and the AP's own related characteristics all use the real global Cell ID information.

After step 507, since the AP has acquired the real global Cell ID, it is related to the prior art. The switching process is the same and will not be described again.

In the foregoing implementation manner, the real cell ID information is obtained on the AP side, and the real RNC ID is also obtained. The AP implements dynamic to real Cell ID conversion, and is used for AP to macro network handover and AP related features. With this method, the RNC ID in the Cell ID can also be dynamized, and will not be described here.

After the AP obtains the mapping relationship between the dynamic global cell identifier and the real global cell identifier, the AP obtains the real global cell identifier and obtains the real RNC ID according to the mapping relationship after receiving the dynamic global cell identifier. After the real global cell identifier is used, the subsequent operations may be performed according to the original method. Therefore, when the dynamic cell identifier is used, the UE may successfully initiate a handover from the Femto cell to the macro cell. In the fifth embodiment, the embodiment uses the dynamic cell ID and the real cell ID mapping key, and the dynamic RNC ID and the real RNC ID mapping key as an example. In this embodiment, the AP will be a dynamic cell. Both the ID and the RNC ID are converted to real. For convenience of description, we call the conversion of the dynamic global Cell ID to the real global Cell ID. As shown in Figure 6, the following steps are included:

Step 601: The RNC network management periodically generates a dynamic and real global Cell ID conversion key K1, and marks the K1 generation time t1. The periodic generation of the conversion key can improve the difficulty of the key being cracked, thereby further improving security. Sex. It is also possible to implement the method of periodically generating a key, which is not limited in the embodiment of the present invention.

Step 602: After generating the key K1, the RNC network management sends the K1 to the RNC and the AP network management system, and the sending information carries the key K1 to generate the time stamp tl; and then the RNC and the AP system (the AP network management system and the AP) respectively obtain the The key K1 converts the global Cell ID:

Step 603: On the RNC side, the real global Cell ID of all the cells in the cell is encrypted by using the obtained key K1, and the dynamic global cell ID is obtained (for example, the global cell ID is Paral), and the Paral is sent in the air interface system message update. ;

Step 604: The AP network management system on the AP system side sends the key K1 with the generated time stamp to all the APs it manages. The AP performs an automatic neighbor search at a certain time and records the execution time t2. The AP can store multiple keys of the generation period. The AP determines the correct key according to the time relationship between the neighbor search time t2 and each key generation time (compared from the latest time t1). The dynamic global Cell ID is decrypted to obtain the real global Cell ID information, which is configured with the real global Cell ID. Macro cell neighborhood. The subsequent AP to macro cell handover and the AP's own related characteristics all adopt real global Cell ID information.

After the AP obtains the translation key of the dynamic global cell identifier and the real global cell identifier, the AP may obtain the real global cell identifier according to the key after receiving the dynamic global cell identifier, and the AP may obtain the real global cell identifier after obtaining the real global cell identifier. Subsequent operations are performed according to the original method. Therefore, when the dynamic cell identity is used, the UE can successfully initiate a handover from the Femto cell to the macro cell. The cell ID sent by the RNC to the AP through the air interface is the dynamic cell ID. The illegal third party cannot obtain the correspondence between the cell ID and the geographic location of the cell, thus improving information security. The sixth embodiment of the present invention further provides a radio network controller, as shown in FIG. 7, which includes:

The global cell identifier sending unit 701 is configured to send a global cell identifier to the access point, where the global cell identifier includes a dynamic cell identifier and a real radio network controller identifier, so that the access point sends the global identifier including the real radio network controller identifier.
