Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The embodiment of the invention is applied to a cell congestion processing system. The cell congestion processing system comprises access network equipment and management and control equipment. The access network equipment and the management and control equipment both comprise a congestion function module, wherein the congestion function module is used for transmitting signaling, and the signaling comprises cell congestion levels. In the existing network architecture, an access network device communicates with a management and control device through a gateway device on the core network side. When the existing network architecture is used, the gateway device at the core network side also contains a congestion function module to realize signaling forwarding between the access network device and the core network device. Taking an LTE network as an example, the access network equipment is an eNodeB network element, the gateway equipment at the core network side comprises an MME network element and a SAEGW network element, and the management and control equipment is a PCRF network element. Adding an eNodeB network element congestion module in an eNodeB network element, adding an MME network element congestion module in an MME network element, adding an SAEGW network element congestion module in an SAEGW network element, adding a PCRF network element congestion module in a PCRF, and forming a signaling transfer channel between the eNodeB network element congestion module and the SAEGW network element congestion module and between the SAEGW network element congestion module and the PCRF network element congestion module. When the eNodeB network element discovers the cell congestion, the MME network element and the SAEGW network element send the cell congestion signaling to the PCRF network element, and the PCRF network element returns corresponding management and control strategies to the eNodeB network element through the MME network element and the SAEGW network element after receiving the cell congestion signaling. The following describes the embodiments of the present invention.
Fig. 1 shows a flowchart of a cell congestion handling method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step 110: the access network device determines a first congestion level of the cell.
Wherein the access network device is a device at the base station side. In an LTE network, the access network device is an eNodeB. The eNodeB is the name of a base station in the LTE network, and is also an access network element of LTE. The access network device is used for controlling the self-accessed cell. The cell congestion level is used to measure the congestion level of a cell. In the embodiment of the invention, the congestion degree of the cell is determined by collecting cell information. The cell information includes a plurality of congestion dimensions, which are indicators of the degree of congestion of the cell. The congestion dimension includes the number of users of a cell, the traffic of a cell, the number of signaling interactions, etc. The relationship between the cell information and the congestion level of the cell may be defined manually by those skilled in the art, and the embodiment of the present invention is not limited thereto.
The congestion degree of the cell is determined according to all the congestion dimensions, each congestion degree corresponds to one congestion level, and the corresponding relationship between the congestion degree and the congestion level is defined by a person skilled in the art, which is not limited by the embodiment of the present invention. For example, the degree of congestion is classified into three types of severe congestion, general congestion, and no congestion, and the corresponding congestion levels are respectively three types of high level, medium level, and low level.
Step 120: the access network equipment compares the first congestion level with the second congestion level, and generates signaling to be sent according to the comparison result.
The second congestion level is used for indicating the last congestion level of the cell, and the signaling to be sent is determined according to the comparison result of the first congestion level and the second congestion level. And determining the specific type of the signaling to be sent according to the comparison result. For example, when the second congestion level indicates that the cell is not congested and the first congestion level indicates that the cell is congested, the signaling to be sent is determined according to the comparison result to be reporting signaling, where the reporting signaling is used to report the cell congestion. Reporting the identifier of the first congestion level carried in the signaling, and facilitating the management and control equipment receiving the signaling to determine a corresponding management and control strategy according to the type of the signaling and the identifier of the first congestion level carried in the signaling. The embodiments of the present invention are not limited to the specific form of identification of the first congestion level. For example, congestion levels are indicated by Arabic numbers, 0 for high congestion levels, 1 for medium congestion levels, and 2 for low congestion levels.
Step 130: the access network device sends the signaling to the management and control device.
In a cell congestion handling system in which an access network device and a management and control device can communicate directly, the access network device sends signaling directly to the management and control device. In a cell congestion handling system in which an access network device and a management and control device cannot directly communicate, the access network device forwards signaling to the management and control device through a third party device. For example, in the LTE system, the signaling generated by the access network device is transmitted to the management and control device through the gateway device on the core network side.
Step 140: and the control equipment matches the corresponding control strategy according to the signaling.
The control strategy is used for controlling the cells. The embodiment of the invention is not limited to the specific content of the management and control strategy. For example, when a cell is congested, the number of terminals accessing the cell may be limited; when congestion is relieved, the number of terminals accessing the cell may be opened. The policy corresponding to each congestion level can be flexibly configured by a person skilled in the art according to the existing cell congestion policy.
Step 150: the management and control device sends the management and control policy to the access network device.
In a cell congestion handling system in which an access network device and a management and control device can directly communicate, the management and control device directly sends a management and control policy to the access network device. In a cell congestion processing system in which access network equipment and management and control equipment cannot directly communicate, the management and control equipment forwards a management and control strategy to the access network equipment through third party equipment. For example, in the LTE system, the management and control device sends the management and control policy to the access network device through the gateway device on the core network side.
Step 160: and the access network equipment controls the cells according to the control strategy.
After the access network equipment determines the cell congestion level, the embodiment of the invention reports the cell congestion level to the management and control equipment in real time, and the management and control equipment issues the management and control strategy through a reporting channel. By the mode, the embodiment of the invention realizes the real-time reporting of the congestion level and avoids the situation that the management and control strategy is not suitable for the current cell.
In some embodiments, the signaling to be sent includes reporting signaling, deleting signaling, and updating signaling. The reporting signaling is used for reporting the cell congestion to the management and control equipment. The deletion signaling is used to report cell congestion cancellation to the management and control equipment. The update signaling is used to report the cell congestion level change to the management and control device.
The reporting signaling is mainly used in the process of converting the non-congestion into the congestion of the cell. And if the second congestion level indicates that the cell is not congested, the first congestion level indicates that the cell is congested, and reporting signaling is generated. Taking LTE network as an example, the reporting flow of the reporting signaling is shown in fig. 2. After the access network equipment eNodeB judges the cell congestion, the access network equipment eNodeB initiates a cell congestion reporting flow to the gateway equipment MME at the core network side, and the generated reporting signaling is a create_cell_congestion_request, and the signaling carries an identifier of a first congestion level, and the identifier is represented by a security_level parameter. In the actual implementation process, the signaling also comprises parameters such as session ID, tracking area code (Tracking area code of cell served by neighbor Enb, TAC), cell identification and the like. As shown in fig. 2, after receiving the report signaling from the eNodeB, the gateway device MME on the core network side forwards the signaling create_cell_event_request to the salgw. After receiving the reporting signaling sent by the MME, the SAEGW forwards the signaling create_cell_control_request to the PCRF. After receiving the signaling sent by the SAEGW, the PCRF responds to a request corresponding to the signaling, determines a corresponding congestion resolution strategy according to a quality_level parameter in the signaling, and gradually returns the congestion strategy to the eNodeB through a create_cell_congestion_response signaling.
Congestion cell deletion occurs mainly in the scenario where a cell transitions from congestion to non-congestion. If the second congestion level indicates that the cell is congested, the first congestion level indicates that the cell is not congested, then a deletion signaling is generated. For example, a star concert is performed somewhere, resulting in cell congestion in the venue, which is eliminated after two hours. Taking LTE network as an example, the reporting flow of deleting signaling is shown in fig. 3. After the access network equipment eNodeB judges that the cell is changed from congestion to non-congestion, the cell congestion deleting process is initiated to the gateway equipment MME at the core network side, the generated reporting signaling is a delete_cell_congestion_request, the signaling carries an identifier of a first congestion level, and the identifier is represented by a security_level parameter. After receiving congestion deletion signaling of eNodeB, gateway equipment MME at core network side forwards signaling delete_cell_congestion_request to SAEGW. After receiving the congestion deletion signaling sent by the MME, the SAEGW forwards the signaling to the PCRF. The PCRF determines a corresponding congestion solving strategy according to the signaling type and the quality_level parameter in the signaling, and gradually returns the congestion strategy to the eNodeB through the delete_cell_congestion_response signaling.
The congestion cell update is mainly used when the cell congestion degree changes. If the second congestion level and the first congestion level are both indicative of cell congestion, generating update signaling when the second congestion level and the first congestion level are different. Taking LTE network as an example, the reporting flow of the update signaling is shown in fig. 4. After the access network equipment eNodeB judges that the first congestion level of the cell is changed compared with the second congestion level, the access network equipment eNodeB initiates a cell congestion update flow to gateway equipment MME at the core network side, and the generated reporting signaling is a modification_cell_congestion_request, and the signaling carries an identifier of the first congestion level, and the identifier is represented by a quality_level parameter. After receiving congestion update signaling sent by eNodeB, gateway equipment MME at core network side forwards the signaling to SAEGW, which forwards the signaling to PCRF. The PCRF determines a corresponding congestion solving strategy according to the signaling type and the quality_level parameter in the signaling, and gradually returns the congestion strategy to the eNodeB through the modification_cell_congestion_response signaling.
In some embodiments, if the second congestion level and the first congestion level are both indicative of cell congestion, reporting signaling is generated when the second congestion level and the first congestion level are the same. By the method, the congestion level is guaranteed to be reported in real time.
In some other embodiments, if the second congestion level and the first congestion level are both indicative of cell congestion, when the second congestion level and the first congestion level are the same, the access network device compares the first congestion level and the third congestion level, and if the first congestion level and the third congestion level are the same and the second congestion level does not generate reporting signaling, generates reporting signaling. Wherein the third congestion level is a previous cell congestion level of the second congestion level. By the mode, the reporting flow is saved.
In one embodiment, the cell congestion level is determined as follows. A congestion threshold and corresponding weights are preset for each congestion dimension. The congestion threshold is used to distinguish between congestion and non-congestion in the congestion dimension. And if one congestion dimension exceeds the congestion threshold corresponding to the congestion dimension, marking the congestion dimension as a first value. If the congestion dimension does not exceed the congestion threshold corresponding to the congestion dimension, the congestion dimension is marked as a second value. The first value and the second value are different values. And weighting and calculating all congestion dimensions and corresponding weights of the cells to obtain congestion scores of the cells. The congestion level corresponding to the score interval to which the congestion score belongs is the congestion level of the cell. Wherein one congestion level corresponds to one fractional interval. For example, the first value is 1, the second value is 0, the cell information acquired by a certain cell includes three congestion dimensions, which are denoted as A1, A2, and A3, and the weights corresponding to the three congestion dimensions are W1, W2, and W3, where both A1 and A3 exceed the normal value of the congestion dimension, and A2 does not exceed the normal value of the congestion dimension, and the congestion score of the cell is 1 xw1+0 xw2+1 xw3=w1+w3.
In other embodiments, the cell congestion level is determined as follows. The cell information includes a plurality of congestion dimensions, each congestion dimension corresponding to a congestion threshold. A congestion dimension exceeding a corresponding congestion threshold is determined as a target congestion dimension. And calculating the number of target congestion dimensions in all congestion dimensions. The congestion level corresponding to the interval to which the number belongs is the first congestion level.
In some embodiments, after determining the first congestion level of the cell according to the acquired cell information, the access network device stores the first congestion level in a preset buffer table, so that the first congestion level is convenient for being used in the subsequent congestion level comparison. Meanwhile, operation and maintenance personnel can analyze the situation of the cell according to the stored congestion level.
