Description
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a method and system for deregistering a base station.
Background
With the development of wireless mobile technology, the concept of home base stations is introduced. The home base station is different from a general macro base station. The femtocell is a small-sized and low-power base station, is deployed in indoor places such as homes, offices and the like, and mainly has the functions of providing higher service rate for users, reducing the cost required by using high-rate services and making up for the defects of coverage of the existing distributed wireless communication system. The home base station has the advantages of practicability, convenience, low power output, plug and play and the like.
A concept of a home base station, called henb (home enodeb), is introduced in a Long Term Evolution (LTE) system, i.e., an evolved home base station. The HeNB is connected to a Core NetWork, such as AN enhanced Packet Core NetWork (EPC), based on a Home eNodeB Access NetWork (HeNB AN), as shown in fig. 1, where the HeNB AN is composed of a HeNB and a Home eNodeB Gateway (HeNB GW, Home eNodeB Gateway). The main executed functions of the HeNB GW are: and verifying the security of the HeNB, processing the registration and access control of the HeNB and taking charge of the data exchange between the core network and the HeNB. The HeMS (Home evolved node B) performs operation maintenance Management on the HeNB, configures and controls the HeNB according to the requirements of an operator, and mainly realizes a configuration Management function for the HeNB, wherein the configuration Management function mainly comprises verification of position information and parameter configuration of the HeNB, and mainly relates to parameter configuration at a core Network level, parameter configuration at a Radio Access Network (RAN) side and parameter configuration at a Radio Frequency (RF). In addition, the HeNB may be directly connected to a Mobility Management Entity (MME) without passing through the HeNB GW.
The HeNB firstly acquires the configuration parameters from the HeMS after being electrified, and notifies the configuration parameters of the HeNB to the HeNB GW or the MME before working. The procedure for the HeNB to notify the configuration parameters to the HeNB GW or MME may be completed through an S1 setup procedure.
Currently, in the existing S1 Application Protocol (S1AP, S1 Application Protocol), only a reset procedure between an evolved macro base station (eNB) and an MME is defined, which can reset a dedicated resource for establishing a User Equipment (UE) between the eNB and the MME, reserve Application layer data interacted when an S1 connection is established between the eNB and the MME, such as GUMMEI information, and do not terminate the operation of the eNB.

Detailed Description
Since the eNB is usually deployed statically by the operator, static configuration is a reasonable implementation for resources between the eNB and the MME, and therefore, in the existing S1AP, there is no related flow for de-registration, so that eNB operation cannot be terminated.
The HeNB can be deployed in many ways, and has the characteristics of strong mobility and plug and play, so that before the HeNB is powered off and powered down, if the HeNB can initiate to delete the resources between the HeNB GW or the MME and inform the HeNB to be registered, the HeNB BGW or the MME can delete the stored related resources of the HeNB; and, under the condition that HeNB GW or MME is overloaded, if HeNB GW or MME can initiate to delete the resources between HeNB, the HeNB GW or MME can delete the stored related resources of HeNB, so that the corresponding eNB can register and terminate the operation of the corresponding HeNB. In addition, it is also a normal requirement for the HeNB as a personal terminal device to actively initiate de-registration and release its own related resources when needed.
In the present invention, the base station de-registration is completed by multiplexing the existing S1 reset message, that is: when the base station needs to terminate the operation, sending an S1 reset message to a control network element which establishes an S1 connection with the base station, wherein the S1 reset message carries base station resource release indication information; or, when the control network element needs to terminate the operation of the base station, sending an S1 reset message to the base station, where the S1 reset message carries base station resource release indication information. Therefore, in the invention, the base station resource release indication information is carried in the existing S1 reset message, so that the base station de-registration is realized.
The base station may be a home base station or a macro base station. The control network element may be a home base station gateway; may also be an MME. When the base station is a home base station, if the home base station is connected with an MME through a home base station gateway, the control network element establishing S1 connection with the base station is the home base station gateway; and if the home base station is directly connected with the MME, the control network element which establishes the S1 connection with the home base station is the MME. And when the base station is a macro base station, the control network element establishing the S1 connection with the base station is an MME.
Case of base station initiated de-registration
After the base station sends an S1 reset message carrying base station resource release indication information to the control network element, the control network element receives an S1 reset message carrying base station resource release indication information and releases related resources of the base station; after receiving the S1 reset message carrying the base station resource release indication information, the control network element may further reply an S1 reset response message to the base station, which may be optional.
If the femtocell is connected with the MME through the femtocell gateway, after receiving the S1 reset message carrying the base station resource release indication information, the femtocell gateway can also send a common S1 reset message to the MME. The ordinary S1 reset message refers to that the message carries not the base station resource release indication information, but the signaling connection of the UE under the home base station. And after receiving the common S1 reset message, the MME releases the special resource of the UE according to the signaling connection of the UE.
After the base station sends the S1 reset message carrying the base station resource release indication information, the relevant resources of the base station can be immediately released and the operation is terminated; or after receiving the S1 reset response message replied by the controlling network element, releasing the relevant resources of the base station and terminating the operation.
Controlling the situation of network element initiating de-registration
And after the control network element sends the S1 reset message carrying the base station resource release indication information to the base station, the base station receives the S1 reset message carrying the base station resource release indication information, releases the related resources of the base station and terminates the operation. After receiving the S1 reset message carrying the base station resource release indication information, the base station may further reply an S1 reset response message to the control network element, which may be optional.
If the femtocell is connected with the MME through the femtocell gateway, after the femtocell gateway sends the S1 reset message carrying the base station resource release indication information, the femtocell gateway can also send a common S1 reset message to the MME. The ordinary S1 reset message refers to that the message carries not the base station resource release indication information, but the signaling connection of the UE under the home base station. And after receiving the common S1 reset message, the MME releases the special resource of the UE according to the signaling connection of the UE.
After the control network element sends an S1 reset message carrying base station resource release indication information, the relevant resources of the base station can be immediately released; or after receiving the S1 reset response message replied by the base station, releasing the relevant resources of the base station.
The released relevant resources of the base station include not only all S1 resources allocated to the corresponding base station, such as a Transmission resource Stream Control Transmission Protocol (SCTP) connection, but also relevant resources of all UEs under the corresponding base station, and also application layer configuration data interacted during the process of establishing the S1 connection by the base station.
The base station resource release indication information carried in the S1 reset message may be a specific special S1 reset reason, a specific resource release indication, or a resource release type.
Specific implementations of the present invention are described in more detail below with reference to the accompanying drawings. For simplicity of description, the base station is mainly taken as the HeNB, and the same is true for the eNB, but the eNB is directly connected with the MME.
Fig. 2 is a schematic diagram of a process of initiating de-registration from a HeNB to a HeNB GW by a HeNB in a first embodiment of the present invention, where this embodiment is applicable to a topology structure in which a HeNB is connected to an MME through a HeNB GW, and as shown in fig. 2, a process of initiating de-registration from a HeNB to a HeNB GW is described, which specifically includes:
step 201: for some reasons, for example, the HeNB is ready to power off, or the operation of the HeNB needs to be terminated because the user is ready to move the HeNB, so that the relevant resources of the HeNB stored on the HeNB GW need to be deleted, and therefore, the HeNB sends an S1 reset message to the HeNB GW, where the S1 reset message carries an HeNB resource release indication.
Step 202: and after receiving the S1 reset message, the HeNB GW replies an S1 reset response message to the HeNB, and releases all related resources of the HeNB according to the HeNB resource release instruction carried in the S1 reset message.
After the HeNB sends the S1 reset message carrying the HeNB resource release indication, all the local related resources of the HeNB can be immediately released and the operation is terminated; or after receiving the S1 reset response message returned by the HeNB GW, releasing all relevant resources local to the HeNB and terminating the operation.
The related resources include not only all S1 resources allocated to the HeNB, such as transmission resources SCTP connection, but also related resources of all UEs under the HeNB, and also application layer configuration data interacted during the process of establishing an S1 connection by the HeNB.
Step 203: because the HeNB GW receives the S1 reset message carrying the HeNB resource release indication, the HeNB GW receives the S1 reset message and then sends a common S1 reset message to the MME, and the common S1 reset message carries the signaling connection identifier of the UE under the HeNB, so as to complete the release of the dedicated resources of the UE related to the corresponding HeNB on the MME. And after receiving the common S1 reset message, the MME releases the special resources of the UE according to the signaling connection identification of the UE under the HeNB.
Step 203 and step 202 are not necessarily performed in a sequential order in terms of execution time, and may be performed after step 201, or may even be performed simultaneously.
The step 202 of replying the S1 reset response message to the HeNB is an optional step, and if the step is omitted, the HeNB may release all the relevant resources local to the HeNB and terminate the operation after sending the S1 reset message carrying the HeNB resource release indication.
Fig. 3 is a schematic diagram of a flow of a registration cancellation process initiated by a HeNB GW to a HeNB in a second embodiment of the present invention, where this embodiment is applicable to a topology structure in which a HeNB is connected to an MME through the HeNB GW, and as shown in fig. 3, a process in which the HeNB GW initiates a registration cancellation to the HeNB is described, which specifically includes:
step 301: for some reasons, for example, the HeNB GW is overloaded, or a network administrator needs to delete all resources of a certain HeNB under the HeNB GW, so as to achieve the effect similar to cell deletion, therefore, the HeNB GW sends an S1 reset message to the HeNB, where the S1 reset message carries a HeNB resource release indication.
Step 302: and after receiving the S1 reset message, the HeNB replies an S1 reset response message to the HeNB GW, releases all the local related resources of the HeNB according to the HeNB resource release instruction carried in the S1 reset message and terminates the operation.
After the HeNB GW sends the S1 reset message carrying the HeNB resource release indication, all relevant resources of the HeNB can be immediately released; or after receiving the S1 reset response message replied by the HeNB, releasing all relevant resources of the HeNB.
The related resources include not only all S1 resources allocated to the HeNB, such as transmission resources SCTP connection, but also related resources of all UEs under the HeNB, and also application layer configuration data interacted during the process of establishing an S1 connection by the HeNB.
Step 303: because the HeNB GW sends the S1 reset message carrying the HeNB resource release indication, the HeNB GW sends the S1 reset message and then sends the ordinary S1 reset message to the MME, and the ordinary S1 reset message carries the signaling connection identifier of the UE under the HeNB, so as to complete the release of the dedicated resources of the UE related to the corresponding HeNB on the MME. And after receiving the common S1 reset message, the MME releases the special resources of the UE according to the signaling connection identification of the UE under the HeNB.
Step 303 and step 302 are not necessarily performed in a sequential order in terms of execution time, and may be performed after step 301, or may even be performed simultaneously.
Replying an S1 reset response message to the HeNB GW in step 302 is an optional step, and if the step is omitted, the HeNB GW may release all relevant resources of the corresponding HeNB after sending the S1 reset message carrying the HeNB resource release indication.
Fig. 4 is a schematic diagram of a flow of initiating a de-registration from an eNB to an MME in a third specific embodiment of the present invention, where this embodiment is applicable to both an eNB and a topology structure in which an HeNB is directly connected to an MME, and for convenience of description, the following is represented by an eNB (H), and as shown in fig. 4, a process of initiating a de-registration from an eNB (H) to an MME is described, which specifically includes:
step 401: for some reasons, for example, (H) eNB is ready to power off, or (H) eNB is ready to move and needs to terminate the operation of (H) eNB, so that the related resource of (H) eNB stored in the MME needs to be deleted, and therefore, (H) eNB sends an S1 reset message to the MME, where the S1 reset message carries a base station resource release indication.
Step 402: and after receiving the S1 reset message, the MME replies an S1 reset response message to the (H) eNB and releases all related resources of the (H) eNB according to the base station resource release instruction carried in the S1 reset message.
(H) After the eNB sends an S1 reset message carrying a base station resource release indication, all local related resources of the (H) eNB can be immediately released and the operation is terminated; or after receiving the S1 reset response message replied by the MME, releasing all relevant resources local to the (H) eNB and terminating the operation.
The related resources include not only all S1 resources allocated to the eNB (H), such as transmission resources SCTP connection, but also related resources of all UEs under the eNB (H), and also application layer configuration data interacted during the process of establishing the S1 connection by the eNB (H).
Replying the S1 reset response message to the (H) eNB in step 402 is an optional step, and if the step is omitted, after the (H) eNB sends the S1 reset message carrying the base station resource release indication, all the related resources local to the (H) eNB may be released and the operation is terminated.
Fig. 5 is a schematic diagram of a flow of initiating a de-registration from an MME to an (H) eNB in a fourth embodiment of the present invention, where this embodiment is applicable to both an eNB and a topology structure in which an HeNB is directly connected to an MME, and for convenience of description, the following is denoted by the (H) eNB, and as shown in fig. 5, a process of initiating a de-registration from an MME to the (H) eNB is described, which specifically includes:
step 501: for some reasons, for example, the MME is overloaded, or a network administrator needs to delete all resources of a certain (H) eNB under the MME, the MME sends an S1 reset message to the (H) eNB, where the S1 reset message carries a base station resource release indication.
Step 502: (H) and after receiving the S1 reset message, the eNB replies an S1 reset response message to the MME, releases all the local related resources of the (H) eNB according to the base station resource release instruction carried in the S1 reset message and terminates the operation.
After the MME sends an S1 reset message carrying a base station resource release instruction, all related resources of the eNB (H) can be released immediately; all relevant resources of the (H) eNB may also be released after receiving the S1 reset response message replied by the (H) eNB.
The related resources include not only all S1 resources allocated to the eNB (H), such as transmission resources SCTP connection, but also related resources of all UEs under the eNB (H), and also application layer configuration data interacted during the process of establishing the S1 connection by the eNB (H).
Replying the S1 reset response message to the MME in step 502 is an optional step, and if this step is omitted, after the MME finishes sending the S1 reset message carrying the base station resource release indication, all relevant resources of the corresponding (H) eNB may be released.

The base station may be a home base station or a macro base station. The control network element may be a home base station gateway; may also be an MME. When the base station is a home base station, if the home base station is connected with an MME through a home base station gateway, the control network element establishing S1 connection with the base station is the home base station gateway; and if the home base station is directly connected with the MME, the control network element which establishes the S1 connection with the home base station is the MME. And when the base station is a macro base station, the control network element establishing the S1 connection with the base station is an MME.
