Description
Technical Field

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1, the MME and the eNB are in communication via an S1 interface, and the eNB and the user are in communication via a Uu interface, where the S1 interface and the Uu interface are both logical interfaces. Therefore, before communication, it is necessary to establish its corresponding S1 interface and Uu interface for each user or cluster. For example, an S1 Bearer is established at an S1 interface for a user or a cluster, and corresponding resources are allocated, a DRB (Data Radio Bearer) is established at a Uu interface, and corresponding resources are allocated, and a context is established for the user or the cluster.
When the MME or the eNB side fails to cause the loss of the information of the user or the information of the cluster stored by the MME or the eNB side, the MME or the eNB side needs to be subjected to the failureThe S1 interface corresponding to the user or cluster is reset so that the MME and eNB maintain the same user or cluster information. Existing 3GPP (3)rdGeneration Partnership Project) R14 protocol gives a procedure to reset when the MME or eNB side fails, resulting in loss of information for the user. For example, as shown in fig. 2, when the MME fails to cause the information of the user to be lost, the MME sends a RESET message (RESET) to the eNB, so that the eNB deletes all information related to the user on the eNB, such as bearer information or context. Alternatively, as shown in fig. 3, when the eNB fails to cause the information of the user to be lost, the eNB sends a reset message to the MME, so that the MME deletes all information related to the user on the MME, such as bearer information or context. However, the prior art is only user-specific, i.e. the reset of the S1 interface is only performed when the MME or eNB finds that the relevant information of the user is lost. With the development of LTE, when an MME or eNB finds that only relevant information of a cluster is lost, the existing technology cannot reset the S1 interface for the cluster alone.
The technical scheme of the embodiment is suitable for an LTE (Long Term Evolution) system, and is used for solving the problem that the prior art cannot only reset the S1 interface for a cluster, and further cannot meet the communication requirement of the LTE system.
Fig. 4 is a flowchart illustrating a first embodiment of a resetting method of the S1 interface according to the present invention. The execution subject of this embodiment is a first communication device, which may be a base station or an MME, and correspondingly, the second communication device is an MME or a base station. The present embodiment relates to a specific process in which the first communication device performs an S1 interface reset when it is determined that cluster information is currently lost. As shown in fig. 4, the method of this embodiment may include:
s101, the first communication device judges whether the current lost information is cluster information.
And S102, if so, the first communication device acquires the identification of the cluster corresponding to the lost cluster information, and sends a reset message to the second communication device, wherein the reset message comprises the identification of the cluster.
Wherein the reset message is used to instruct the second communication device to delete all information related to the cluster on the second communication device; the first communication device and the second communication device have an S1 interface therebetween.
Specifically, the first communication device and the second communication device of this embodiment have an S1 interface therebetween, that is, the first communication device and the second communication device communicate through an S1 interface, as shown in fig. 1, in the LTE system, when the first communication device is a base station, the second communication is set to be an MEE, and when the first communication device is an MEE, the second communication device is a base station.
In an actual use process, when the first communication device fails (for example, a physical failure or power failure, etc.), the first communication device detects, in real time or intermittently, whether cluster information (for example, information such as an identifier or a bearer of a cluster) currently stored thereon is lost according to a related instruction. If the first communication device judges that the related information of a certain cluster is lost currently, the first communication device obtains the identifier of the cluster losing the cluster information, carries the identifier of the cluster in the reset message, and sends the reset message to the second communication device.
The information that the first communication device determines that the first communication device is currently lost may be partial information of a certain cluster, or may be all information of the cluster. When the first communication device loses all information of the cluster, then the first communication device need not perform a delete action of the cluster on it. When the first communication device loses part of the information of the cluster, the first communication device deletes all the information corresponding to the cluster on the first communication device, and the specific process refers to the description of the subsequent embodiments.
S103, the second communication device receives the reset message sent by the first communication device.
S104, the second communication device deletes all information related to the cluster on the second communication device according to the identification of the cluster.
Specifically, the second communication device receives a reset message sent by the first communication device, obtains the identifier of the cluster from the reset message, and deletes all information related to the cluster on the second communication device according to the identifier of the cluster. For example, the resources allocated to the cluster on the second communication device (e.g., data channel resources and cluster bearer resources of the core network) are deleted, and the context of the cluster (e.g., an S1Application Protocol (S1Application Protocol, abbreviated as S1AP) ID, a cluster identifier, a cluster priority, and the like) is removed, so as to implement resetting of the S1 interface corresponding to the cluster on the second communication device.
In this embodiment, when the first communication device determines that the first communication device is currently lost as the user information, optionally, the identifier of the user may be carried in the Reset message, so that the second communication device deletes all information corresponding to the user, or the Reset all connection may be carried in the Reset message, so that the second communication device resets S1 interfaces corresponding to all users. When the first communication device determines that the first communication device currently loses both the user message and the cluster information, the first terminal device may carry both the identifier of the user losing the information and the identifier of the cluster in the reset message, and send the reset message to the second communication device, so that the second communication device deletes all the information of the user and all the information of the cluster on the second communication device. Optionally, when the first communication device finds that information of a plurality of users or information of a plurality of clusters is lost, the RESET ALL may be carried in the RESET message, so that the second communication device deletes ALL information of S1 interfaces corresponding to ALL users and clusters thereon.
S105, the second communication device sends a reset response to the first communication device, where the reset response is used to notify the first communication device that all information related to the cluster has been deleted by the second communication device.
S106, the first communication device receives the reset response sent by the second communication device.
Specifically, when the second communication device deletes all information of the cluster indicated by the reset message on the second communication device according to the reset message, the second communication device sends a reset response to the first communication device, so as to notify the first communication device that all information related to the cluster has been deleted by the second communication device at this time.
Optionally, the reset response may carry an identifier of the cluster deleted by the second communication device, so that the first communication device learns from the reset response that the second communication device has completed resetting the S1 interface corresponding to the cluster, so as to perform subsequent other operations, for example, delete all information of the S1 interface corresponding to the cluster thereon, or newly establish an S1 interface of the cluster, and the like.
In the reset method of the S1 interface of this embodiment, when the first communication device determines that the currently lost information is the cluster information, the first communication device obtains the identifier of the cluster corresponding to the lost cluster information, and sends the identifier of the cluster to the second communication device by carrying the identifier of the cluster in the reset message, so that the second communication device deletes all information related to the cluster on the second communication device according to the identifier of the cluster, thereby implementing the reset of the S1 interface for the cluster when the first communication device loses the cluster information.
Fig. 5 is a schematic flowchart of a flow of an embodiment of a reset method of the S1 interface provided in this embodiment, and fig. 6 is another schematic flowchart of a second embodiment of the reset method of the S1 interface provided in this embodiment. On the basis of the foregoing embodiment, this embodiment relates to a specific process of resetting an S1 interface corresponding to a cluster when the first communication device is a base station or an MME and the second communication device is an MME or a base station.
In the above S101, when the first communication device determines that the currently lost information is the cluster information and determines that the lost cluster information is the partial information related to the cluster, the method of this embodiment further includes: the first communication device deletes all information on the first communication device that is relevant to the cluster.
Specifically, when the first communication device determines that the first communication device currently loses only part of the information of the cluster (for example, only loses the S1AP ID of the cluster) instead of all the information of the cluster, the first communication device obtains the identification of the cluster losing the information, and deletes all the information related to the cluster on the first communication device. This step may be performed after the first communication device sends the reset message to the second communication device in S102, may be performed before the first communication device sends the reset message to the second communication device in S102, and may be performed after S106. Resetting of the S1 interface corresponding to the cluster on the first communication device is achieved, so that the user information and the cluster information on the first communication device are consistent with the user information and the cluster information on the second communication device.
As shown in fig. 5, in a possible implementation manner of this embodiment, if the first communication device is a base station and the second communication device is an MME, the process of resetting, by the base station and the MME, an S1 interface corresponding to a cluster may include:
s201, the base station judges whether the current lost information is partial information of the cluster.
And S202, if so, deleting all information of an S1 interface and all information of a Uu interface related to the cluster on the base station by the base station.
Specifically, if the first communication device is a base station and the second communication device is an MME, when the base station determines that the information lost on the base station is part of information of a cluster, the base station deletes all information related to the cluster on the base station, specifically, deletes all information of an S1 interface and all information of a Uu interface related to the cluster on the base station, that is, deletes resources (e.g., data channel resources and cluster bearer resources associated with a core network) allocated on an S1 interface and the Uu interface related to the cluster, and removes a context of the cluster (e.g., eNB GROUP S1AP ID, cluster identifier, cluster priority, etc.).
S203, the base station sends a reset message to the MME, wherein the reset message comprises the cluster identifier.
The reset message is used to instruct the MME to delete all information of the S1 interface on the MME related to the cluster.
S204, the MME receives the reset message sent by the base station.
S205, the MME deletes all information of the S1 interface related to the cluster on the MME according to the identification of the cluster.
S205 is a specific process of S104, wherein S202 may be executed before S203, after S203, or both, and may also be executed after S106.
Specifically, when the first communication device is a base station and the second communication device is an MME, the base station sends a reset message to the MME, where the reset message carries an identifier of a cluster corresponding to cluster information lost on the base station. The MME deletes all information of the S1 interface related to the cluster on the MME according to the identifier of the cluster carried in the reset message, specifically, releases all allocated resources (e.g., user data transmission resources, signaling resources) related to the cluster on the S1 interface, and removes the MME GROUP S1AP ID of the cluster.
As shown in fig. 6, in another possible implementation manner of this embodiment, if the first communication device is an MME and the second communication device is a base station, a process of the base station and the MME resetting an S1 interface corresponding to a cluster may include:
s301, the MME judges whether the current lost information is part of the cluster information.
And S302, if so, deleting all information of the S1 interface related to the cluster on the MME by the MME.
Specifically, if the first communication device is an MME, the second communication device is a base station, and the MME determines that the information lost on the MME is partial information of the cluster, the MME deletes all information related to the cluster on the MME, specifically deletes all information of the S1 interface related to the cluster on the MME, that is, releases all allocated resources (e.g., user data transmission resources and signaling resources) related to the cluster on the S1 interface, and removes the MME GROUP S1AP ID of the cluster.
S303, the MME sends a reset message to the base station, wherein the reset message comprises the identification of the cluster.
The reset message sent by the MME to the base station is used to instruct the base station to delete all information of the S1 interface and all information of the Uu interface on the base station related to the cluster.
S304, the base station receives the reset message sent by the MME.
S305, the base station deletes all information of an S1 interface and all information of a Uu interface related to the cluster on the base station.
S305 is a specific process of S104, wherein S302 may be performed before S303, after S303, or both, or after S106.
Specifically, when the first communication device is an MME and the second communication device is a base station, the MME sends a reset message to the base station, where the reset message carries an identifier of a cluster corresponding to cluster information lost on the MME. The base station deletes all information of the S1 interface and all information of the Uu interface related to the cluster on the base station according to the cluster identifier carried in the reset message, that is, deletes resources (e.g., data channel resources and cluster bearer resources with the core network) allocated on the S1 interface and the Uu interface related to the cluster, and removes the context of the cluster (e.g., eNB GROUP S1AP ID, cluster identifier, cluster priority, etc.).
In this embodiment, an MME fails to cause cluster information on the MME to be lost, and when the MME corresponds to multiple base stations, the MME sends a reset message to each base station, so that each base station determines whether cluster information corresponding to an identifier of a cluster is stored on the MME, and if so, deletes all information of an S1 interface and all information of a Uu interface related to the cluster. Optionally, when the MME corresponds to multiple base stations, the MME determines which base stations store the information of the cluster (i.e., determines which base stations establish the S1 interface of the cluster with the MME), and the MME sends a reset message to the base stations storing the cluster information, so that the base stations delete all information of the S1 interface and all information of the Uu interface related to the cluster.
In the reset method for the S1 interface provided in the embodiment of the present invention, when the first communication device is a base station, the second communication device is an MME, the base station deletes all information of the S1 interface and all information of the Uu interface related to the cluster on the base station, the MME deletes all information of the S1 interface related to the cluster on the MME, when the first communication device is an MME, and the second communication device is a base station, the MME deletes all information of the S1 interface related to the cluster on the MME, and the base station deletes all information of the S1 interface and all information of the Uu interface related to the cluster on the base station, so that when the base station or the MME loses cluster information, the S1 interface corresponding to the cluster is reset, thereby ensuring that the base station and the MME store the same cluster information.
