Description

Radio network controller, base station and method for eliminating conflict code resources

The present invention relates to the field of communications technologies, and in particular, to a method for troubleshooting a radio network controller, a base station, and a conflicting code resource. Background technique

In the Universal Mobile Telecommunications System (UMTS), there are two types of codewords. The first one is called a channelization code (CH). The two types are called Scrambling code (SC). Since the two codewords are processed differently in the uplink and downlink, the roles of the two codewords are different. In the downlink direction, the CH is used to distinguish different user information of the same cell. SC is used to distinguish between different cells.

In the downlink direction, when the base station (NodeB) sends information to the user equipment (User Equipment, UE for short) in the cell, the NodeB first multiplies the various user information with the respective CHs, and then The multiplied signals are superimposed, and finally the superimposed signals are multiplied by the SC, and the multiplied signals are transmitted on the air interface, and the UE first uses the same information in order to obtain the user information sent by the NodeB to the UE. The SC descrambles the signal sent by the NodeB, and then uses its own CH to solve its useful information from the descrambled signal.

In order to achieve the above signal transmission process, the radio network controller (Radio Ne twork

Contro ller, referred to as RNC, needs to allocate different CHs to different users according to the service type, that is, the radio link establishment/reconfiguration message of the RNC through the IUB interface (the IUB interface is the logical interface between the RNC and the NodeB) will be allocated. The CH information of the UE is notified to the NodeB, and the RNC notifies the UE of the CH information allocated to the UE through the port (the UU port is an interface between the UE and the RNC). By informing the NodeB and the UE in advance, it is to ensure that the signal sent by the NodeB transmitter can be correctly solved by the UE. However, when the RNC side releases the CH allocated to a user and the NodeB does not release the corresponding CH, the RNC may reassign the newly released CH to other users, and notify the NodeB to reassign the CH to the other at the RNC. If the user uses the CH to perform data transmission, the NodeB will receive some incorrect information. Summary of 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 a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The radio network controller, the base station, and the method for excluding the conflict code resources provided by the embodiments of the present invention are applicable to the schematic diagram of the communication system shown in FIG. 1. The system includes a radio network controller (Radio Network Controler) (referred to as RNC) 101 and Base station (NodeB) 102. The RNC 101 allocates different channelization codes (CH) to the different user equipments (User Equipments, referred to as UEs) served by the NodeB 102 according to the service type, and then establishes a radio link establishment process initiated by the RNC 101 or In the radio link reconfiguration process, the same channelization code (CH) information is configured on the NodeB 02 side and the UE side served by the NodeB 102. After the configuration is successful, the UE can use the configured CH to extract its useful information from the information sent by the NodeB 102.

When the RNC side releases the CH allocated to a user and the NodeB does not release the corresponding CH, the RNC may reassign the newly released CH to other users, and notify the NodeB to the other at the RNC through the radio link establishment procedure. When the user configures the CH, the NodeB side will detect the abnormal condition of the same CH configuration to different users. To eliminate the abnormal situation, the present invention provides the following embodiments. FIG. 2 is a schematic structural diagram of a radio network controller according to an embodiment of the present invention, where the radio network controller RNC includes: The conflict message receiving module 201 is configured to receive a message that is sent by the base station, and is used to indicate a codeword conflict, where the message used to indicate the codeword conflict includes a first channelization code, where the first channelization code is in the same The same channelization code used by the respective wireless links of at least two users in the cell.

The message for indicating a codeword conflict is a radio link failure indication message.

The first conflict elimination module 202 is configured to enable the NodeB to retain the first channelization code only on the wireless link of the first user, where the first user is one of the at least two users.

In the embodiment of the present invention, after the NodeB detects that the same channelization code (the first channelization code) is configured to the codeword conflict phenomenon of different users, the message that is used to indicate the codeword conflict is reported to the RNC, so that the RNC can The process of generating the first channelization code excludes the codeword collision phenomenon. Specifically, the embodiment of the present invention provides the following processes for generating the first channelization code and corresponding manners for eliminating the conflict phenomenon of the codeword. Manner 1: Referring to one of the signaling interaction diagrams of the process of generating a collision channelization code shown in FIG. 3: Step 301: After the radio network controller RNC sends a radio link deletion message to the NodeB, the radio link delete message The radio link deletion message is used to notify the NodeB to release the first radio link resource of the user A that includes the first channelization code, where the IUB port is an RNC and The logical interface between NodeBs.

Step 302: When the RNC side times the link deletion time, the RNC deletes the first radio link resource, and after the RNC deletes the first radio link resource, the RNC allocates the first channelization code to the RNC. User B.

Step 303: The RNC sends a radio link setup message to the NodeB, where the radio link setup message is used to notify the NodeB to configure the second radio link resource of the user B that includes the first channelization code.

In the first mode, although the radio link deletion message is discarded due to congestion of the IUB port signaling plane, the NodeB fails to receive the radio link deletion message, but once the timer on the RNC side times out, the RNC is Delete the first radio link resource. The first channelization code is also released at the same time as the first radio link resource is deleted. At this time, the RNC may allocate the released first channelization code to other users than the user A, such as the user 8. When the RNC initiates a radio link setup procedure to cause the NodeB to configure the second radio link resource of the user B that includes the first channelization code, the NodeB will The first channelization code is detected and configured to be sent to the user A and the user B. The same channelization code can be configured to the same user. Therefore, after detecting the codeword conflict, the NodeB reports the first to the RNC. A message of the channelization code indicating a codeword collision, so that the RNC resolves the codeword collision phenomenon.

In order to solve the above-mentioned codeword conflict phenomenon, after receiving the message for indicating the codeword conflict, the RNC may send a radio link deletion message to the NodeB again to release the first channelization code configured to the user A, thereby eliminating The codeword conflict phenomenon. Therefore, the first conflict elimination module 202 can use the following submodules to exclude codeword conflicts:

a request sending submodule, configured to send a radio link deletion message to the NodeB, to enable the NodeB to release a radio link using the first channelization code of other users of the at least two users except the first user ;

a response receiving submodule, configured to receive, by the NodeB, a successful release notification that is returned after the wireless link using the first channelization code of the other users of the at least two users except the first user is successfully released Response message. Method 2: Referring to the signaling interaction diagram of the conflicting channelization code generation process shown in FIG. 4: Step 401: The source radio network controller (Source Radio Ne twork Cont roler, SRNC for short) initiates a radio link. The reconfiguration process reconfigures parameters in the first radio link resource of the established user A. First, SRNC to Drift Radio Network Controller (Dr i f t Rad io

Ne twork Cont roler (DRNC) sends a first radio link reconfiguration preparation message, where the message carries a new configuration (including a new channelization code).

Step 402: The DRNC sends a radio link reconfiguration preparation message to the NodeB, where the message carries a new configuration (including a new channelization code).

Step 403: The NodeB sends a radio link reconfiguration ready message to the DRNC.

Step 404: The DRNC sends a radio link reconfiguration ready message to the SRNC.

Step 405: The SRNC sends an air interface reconfiguration message to the UE of the user A, so that the new configuration (including the new channelization code) is carried by the message, and the activation time of the configuration is valid. The purpose of sending the activation time is to enable the UE when the activation time comes. Enable the new configuration.

Step 406: The SRNC sends a radio link reconfiguration submission message to the DRNC, where the message carries The effective activation time is set. The purpose of sending the activation time is to enable the DRNC to enable the new configuration when the activation time comes.

Step 407: The DRNC sends a radio link reconfiguration commit message to the NodeB, where the message carries the activation time of the configuration effective. The purpose of sending the activation time is to enable the NodeB to enable the new configuration when the activation time comes.

Step 408: The DRNC side resource protection timer may time out when the NodeB side has not reached the activation time because the activation time of the DRNC side is not correct (such as a clock offset). At this time, the DRNC releases the user A. The link resources occupied before reconfiguration include the old channelization code (ie, the first channelization code).

Step 409: The released channelization code (first channelization code) is allocated to other users, such as user B, by the DRNC. The DRNC initiates a radio link setup procedure before the UEs of the NodeB and the user A switch to the new configuration, the purpose of which is to configure the second radio including the first channelization code for the user B on the UE side of the NodeB and the user B. Link resource.

In step 408 and step 409, the DRNC releases the first channelization code in the first radio link resource earlier than the NodeB in the process of reconfiguring the first radio link resource of the user A initiated by the SRNC; Before the NodeB releases the first channelization code, the DRNC allocates the first channelization code to the user B, and sends a radio link setup message to the NodeB, where the radio link setup message is used to notify the NodeB to configure the User B's second radio link resource containing the first channelization code. At this time, the NodeB will detect that the first channelization code is simultaneously configured to the user A and the user B. Since the same channelization code can only be allocated to the same user, after detecting the codeword conflict phenomenon, the NodeB will The RNC reports a message indicating a codeword conflict carrying the first channelization code, so that the RNC resolves the codeword collision phenomenon.

Step 41: When the UE of the NodeB and the user A arrives at the respective activation time, both the NodeB and the UE of the user A switch to the reconfigured resource.

In step 41 0, when the NodeB switches to the reconfigured resource, the NodeB releases the first channelization code configured for the user A, and the first channelization code is only configured to the user B, therefore, Codeword conflicts are only a short process. Therefore, the radio network controller determines, in the drift radio network controller DRNC, that the first channelization code has been released by other users of the at least two users except the first user. Next, the first conflict is excluded The module 202 may discard the message for indicating a codeword conflict after receiving the message for indicating a codeword conflict, to wait for the codeword conflict phenomenon to be customized.

Step 41 1: The UE sends back an air interface reconfiguration complete message to the SRNC using the new configuration. Mode 3: Referring to the signaling interaction diagram of the conflicting channelization code generation process shown in FIG. 5: Step 501: The first channelization code in the first radio link resource of user A is not normally released in the NodeB, and After the RNC normally releases the first channelization code in the first radio link resource of user A,

The RNC assigns the first channelization code to User B.

Step 501 has the following two implementation modes:

1. In the radio link deletion process initiated by the RNC, when the time-to-link deletion time (ie, the activation time) is reached, the NodeB does not normally release the first radio link resource of the user A that includes the first channelization code. The RNC normally releases the first radio link resource.

2. In the radio link reconfiguration process initiated by the RNC, when the time-to-receive resource switching time (ie, the activation time) is reached, the NodeB does not normally release the first channelization code of the first radio link resource of the user A, and the RNC is normal. The first channelization code is released.

Step 502: After the RNC normally releases the first channelization code in the first radio link resource of the user A, the RNC allocates the first channelization code to the user B, and sends a radio link setup message to the NodeB. The radio link setup message is used to notify the NodeB to configure the second radio link resource of the user B that includes the first channelization code.

In the third mode, the first channelization code is not normally released due to the internal reason of the NodeB. Therefore, when the RNC initiates the radio link establishment process, the NodeB configures the second radio link resource of the user B that includes the first channelization code. The NodeB will detect that the first channelization code is configured to both user A and user B. Since the same channelization code can only be assigned to the same user, after detecting the codeword collision phenomenon, the NodeB will send the RNC to the RNC. A message carrying a first channelization code for indicating a codeword conflict is reported, so that the RNC resolves the codeword collision phenomenon.

In order to solve the foregoing codeword conflict phenomenon, after receiving the message indicating the codeword conflict, the RNC may send a radio link deletion message to the NodeB to release the first channelization code configured to the user A, thereby eliminating the Codeword conflicts. Therefore, the first conflict elimination module 202 can use the following submodules to exclude codeword conflicts: a request sending submodule, configured to send a radio link deletion message to the NodeB, to enable the NodeB to release a radio link using the first channelization code of other users of the at least two users except the first user ;

a response receiving submodule, configured to receive, by the NodeB, a successful release notification that is returned after the wireless link using the first channelization code of the other users of the at least two users except the first user is successfully released Response message. Mode 4: Referring to the signaling interaction diagram of the conflicting channelization code generation process shown in FIG. 6: Step 601: The radio network controller RNC abnormally releases the first channel in the first radio link resource of the user A. When the code is coded, and the NodeB is still configured with the first channelization code in the first radio link resource of the user A, the RNC allocates the first channelization code to the user B.

Step 602: Send a radio link setup message to the NodeB, where the radio link setup message is used to notify the NodeB to configure the second radio link resource of the user B that includes the first channelization code.

In mode 4, when the RNC initiates a radio link setup procedure to enable the NodeB to configure the second radio link resource of the user B that includes the first channelization code, the NodeB will detect that the first channelization code is simultaneously configured. User A and user B are given, because the same channelization code can only be assigned to the same user, after detecting the codeword collision phenomenon, the NodeB reports to the RNC a message indicating the codeword conflict carrying the first channelization code. , in order for the RNC to resolve codeword conflicts.

In order to solve the above-mentioned codeword conflict phenomenon, after receiving the message for indicating a codeword conflict, the RNC may discard the message indicating the codeword conflict if it is determined that the codeword conflict phenomenon is only a short process. , to wait for the codeword conflict phenomenon to disappear automatically, otherwise the codeword conflict phenomenon can be eliminated through the wireless link reconstruction or the wireless link deletion process. Therefore, the first conflict elimination module 202 includes:

The first wireless link is the other than the first user among the at least two users. The user's wireless link using the first channelization code.

For a more convenient understanding of the implementation scenario of the message discarding sub-module, the following is an example of the signaling interaction diagram of the conflicting channelization code generation process shown in FIG. 7:

Step 701: The RNC initiates a first radio link reconfiguration process, and reconfigures parameters in the first radio link resource of the established user A. First, the RNC sends a radio link reconfiguration preparation message to the NodeB, which carries a new configuration, and the new configuration includes a new codeword (ie, a first channelization code).

Step 702: The NodeB sends a radio link reconfiguration ready message to the RNC.

Step 703: The RNC sends an air interface reconfiguration message to the UE of the user A, to carry a new configuration by using the message (the new configuration includes the new codeword, the new codeword is the first channelization code), and the configuration takes effect. The activation time, which is used to enable the UE to enable the new configuration when the activation time is reached.

Step 704: The RNC sends a radio link reconfiguration commit message to the NodeB, where the message carries an activation time that is validated by the configuration, and the activation time is used to enable the NodeB to enable the new configuration of the user A when the activation time is reached.

Step 705: The RNC abnormally releases the new codeword (first channelization code) of the user A, and reassigns the old codeword of the user A to the user A, and then the RNC initiates the second radio link reconfiguration process. The purpose is to restore the old configuration of user A, and delete the new configuration of user A (the new configuration includes the new codeword, the new codeword is the first channelization code), and the phenomenon of such resource backoff may occur. It is caused by the reset of the Signaling Radio Bearer (SRB).

Step 706: The RNC allocates the released new codeword (first channelization code) to the user B, and sends a radio link setup message to the NodeB, where the radio link setup message is used to notify the NodeB to configure the user. A second radio link resource of B comprising the first channelization code.

Step 707: Since the RNC has sent a radio link reconfiguration commit message carrying the activation time to the NodeB during the first radio link reconfiguration process, the NodeB switches to the new configuration after the timing reaches the activation time.

The NodeB configures a new codeword for User A due to the first radio link reconfiguration process. After the RNC sends a radio link setup message to the NodeB, the NodeB side configures a new codeword for User B (the first channel). Code), so NodeB will detect codeword conflicts. However, the second time The line link reconfiguration process will eventually release the new codeword (first channelization code). At that time, the first channelization code is only configured to user B. Therefore, the codeword collision phenomenon is only a short process, so when RNC After receiving the message for indicating a codeword conflict, the message for indicating a codeword conflict is discarded, so as to wait for the codeword conflict phenomenon to be customized.
