Description
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to an information processing method and apparatus in a network element handover process, and a network element device.
Background
In the field of mobile communication technology, third and fourth generation user terminals UE perform services by communicating with a base station. The UE accesses the base station in two processes, initial access is selected by the cell and access is accessed by handover. In the two processes, the UE information acquired by the base station is not completely consistent.
Taking a 4G LTE base station as an example, the following briefly describes the processing of the existing base station handover process, where the 3G base station has similar flows, and in the network element handover process, the source base station may send a handover request message to go through two interfaces, i.e., an S1 interface and an X2 interface, specifically as follows: (1) referring to fig. 1, a source base station initiates a Handover preparation process, selects an interface S1, the source base station constructs an S1 Handover Required message and sends the message to a core network, the core network searches for a target base station according to the message, and reconstructs a Handover Request message S1 Handover Request sent to the target base station, so that the Handover preparation Request process of the source base station is completed. (2) Referring to fig. 2, if the source base station and the target base station have an X2 link on an X2 interface, and the handover procedure selects an X2 interface. The source base station directly constructs a Handover Request message X2 Handover Request and sends the Handover Request message to the target base station without interacting network side messages through a core network. Wherein, the existing interface on the network side of the base station strictly follows the interface defined by the standard 3 gpp. After the UE accesses the base station through the handover process, the base station cannot acquire other information that the UE is useful for in the source station. In the method of implementing base station switching through the S1 interface, the switching preparation process is processed by the core network, and the third party network element of the core network cannot complete the transmission of the custom cell, so that according to the conventional simple method, the equipment manufacturer cannot successfully transmit the custom cell to the target base station by adding the network side custom message or the custom cell in the S1 message.
In summary, when accessing the base station through the handover process, due to the restriction of the message, other UE information, such as the RRC connection request reason of the UE, for example, the mobile user identifier, the algorithm process information in the service process of the manufacturer-defined UE, and the like, cannot be obtained. These information are necessary input parameters for some special algorithms implemented by the base station, and the base station cannot acquire the information again by initiating the procedure after the UE is successfully connected. Therefore, the lack of such information leads to incomplete coverage of the feature algorithm function of the base station, which affects the quality of service and user experience of the mobile communication system.

Fig. 3 schematically shows a flowchart of an information processing method in a network element handover process according to an embodiment of the present invention. In the embodiment of the present invention, a base station handover process is taken as an example for description. The information processing method in the network element switching process provided by this embodiment is implemented at the source base station side. Referring to fig. 3, the information processing method in the network element switching process according to the embodiment of the present invention specifically includes the following steps:
s101, adding the UE additional information to an additional information inserting position appointed in the switching request message in advance.
The additional information insertion position in this embodiment is a non-critical extension position of an agreed sub-cell in an RRC container node (handover preparation information Inter-node) carried by the handover request message. Preferably, the selected non-critical extension location is a relatively late location to avoid as much as possible the impact of the additional information on other information in the RRC container node. The UE additional information comprises the manufacturer-defined UE information which is not added by the current 3gpp protocol.
In practical applications, the additional information insertion location is first predetermined, i.e. the location where the additional information is placed in the handover message is determined. Specifically, a non-critical extension position of an approximate sub-cell in a handover preparation RRC container node cell in a handover request message in a handover preparation procedure of a source base station may be selected. When the source base station triggers the switching process, the UE additional information is added to an additional information inserting position appointed in the switching request message in advance, so that the additional information becomes a child node of the switching preparation RRC container node as an open type child cell. The order position of the additional information in the non-critical extension is predetermined, so that the position of the additional information is not informed through extra process interaction.
S102, coding the switching request message carrying the UE additional information according to a predetermined abstract syntax definition 1ASN.1 coding mode to obtain a corresponding switching message code stream.
In the embodiment of the present invention, the coding mode of the handover request message needs to be agreed as the asn.1 coding mode in advance in the communication protocol standard. Then, after the source base station constructs the switching request message carrying the additional information, the switching request message carrying the additional information completes the coding of the message according to the coding mode of the ASN.1 agreed by the protocol standard.
S103, sending the switching message code stream to a target network element so that the target network element can analyze the UE additional information from the switching message code stream.
In the information processing method in the network element switching process provided by the embodiment of the invention, the additional information of the UE is transmitted from the source base station to the target base station by appointing an extension field in the switching request message in advance as the insertion position of the additional information, so that the switched target base station can acquire some missing information of the accessed new user terminal UE through the switching process, the UE information completeness of the target base station is enhanced, the original information is provided for various algorithms developed by a UE manufacturer, and the completeness of different scenes for realizing the algorithms is enhanced. Moreover, the switching request message added with the extension field can be completely compatible and analyzed by other base stations realized by standard interfaces after being coded, the added additional information can be ignored, and no compatibility influence exists.
In the embodiment of the present invention, adding the UE additional information to the additional information insertion location agreed in the handover request message in advance in S101 specifically includes the following steps not shown in the following drawings:
a11, constructing the UE additional information according to the UE information to be transmitted and a pre-configured information structure. The UE information is manufacturer-defined UE information which is not added by the current 3gpp protocol.
A12, encoding the UE additional information into open type data, and adding the encoded UE additional information into a non-critical extended position of the sub-cell in the RRC container node. Wherein, the open type belongs to a data structure type defined in the ASN.1 decoding mode.
In this embodiment, a base station pre-configures a set of information structure of additional information, and when a source base station triggers a handover switching-out process, the source base station constructs UE additional information according to the pre-configured information structure, converts the UE additional information into open type data in an asn.1 code, and adds the open type data to an additional information insertion position, thereby implementing construction of a handover request message carrying the additional information.
In the embodiment of the present invention, after the adding the UE additional information to the additional information insertion location agreed in the handover request message in advance, the method further includes the following steps: and adding identification information in the switching request message, wherein the identification information is used for indicating whether the switching request message carries the UE additional information. In the embodiment of the invention, the identification information is added in the switching request message, so that the target base station can judge whether the UE additional information exists in the additional information insertion position appointed in the switching request message or not by acquiring the identification information after receiving the switching message code stream sent by the source base station.
The embodiment of the invention can supplement the acquisition of some missing information of the new user terminal UE accessed by the target base station through the switching process, enhance the UE information integrity of the target base station, provide original information for manufacturers to develop various algorithms, and enhance the integrity of different scenes for realizing the algorithms. Moreover, the embodiment of the invention does not change the standard of the network side message interface, the coded message can be completely compatible and analyzed by the base station realized by other standard interfaces, the added additional information can be ignored, and no compatible influence can be caused.
Fig. 4 schematically shows a flowchart of an information processing method in a network element handover procedure according to another embodiment of the present invention. In the embodiment of the present invention, a base station handover process is taken as an example for description. The information processing method in the network element switching process provided by this embodiment is implemented at the target base station side. Referring to fig. 4, the information processing method in the network element switching process according to the embodiment of the present invention specifically includes the following steps:
s201, receiving a switching message code stream sent by a source network element.
In the embodiment of the invention, the source network element is the source base station, and the switching message code stream is obtained by coding the switching request message triggered by the source base station.
S202, decoding the switching message code stream according to a predetermined abstract syntax definition 1ASN.1 coding mode to obtain a corresponding switching request message.
In the embodiment of the present invention, the decoding mode of the handover request message needs to be agreed as the asn.1 decoding mode in advance in the communication protocol standard. And then, after the target base station receives the switching message code stream of the network side, the decoding of the switching request message is completed according to the decoding mode of the ASN.1 agreed by the protocol standard.
S203, judging whether UE additional information exists in an additional information insertion position appointed in the switching request message, wherein the additional information insertion position is a non-critical extended position of an about sub-cell in an RRC container node carried by the switching request message.
In practical application, when the source base station triggers the handover switching-out process, the UE additional information is added to the additional information insertion position agreed in the handover request message in advance. The order position of the additional information in the non-critical extension is predetermined, so that the position of the additional information is not informed through extra process interaction. The additional information becomes a child node of the handover preparation RRC container node as an open type child cell.
If the additional information insertion location has the UE additional information, step S204 is executed, otherwise step S205 is executed.
S204, extracting the UE additional information, and executing the step S205.
S205, executing the network element switching operation according to the current switching request message.
In the embodiment of the invention, after the decoding operation of the code stream is finished, whether the decoded switching request message has additional information is further judged. If the additional information exists, the additional information cell is taken out and stored for subsequent use, and then corresponding switching operation is executed according to the switching request message extracted by the additional information; and if the additional information does not exist, the target base station executes corresponding switching operation according to the conventional process of processing the switching request message. The present invention is not specifically described with respect to a conventional procedure for processing a handover request message.
In practical application, after the source base station adds the UE additional information to the additional information insertion location agreed in the handover request message in advance, an identification information is added to the handover request message to indicate whether the handover request message carries the UE additional information. Therefore, the embodiment of the present invention may specifically determine whether the additional information exists in the additional information insertion location agreed in the handover request message by the following steps, including: acquiring identification information carried by the switching request message, wherein the identification information is used for indicating whether the switching request message carries the UE additional information or not; and judging whether the additional information of the UE exists in the additional information inserting position appointed in the switching request message or not according to the identification information.
In the embodiment of the present invention, the extracting the UE additional information in S204 specifically includes the following steps that are not shown in the following drawings:
and B11, decoding the UE additional information according to an open type. Wherein, the open type belongs to a data structure type defined in the ASN.1 decoding mode.
B12, analyzing the decoded UE additional information according to the preconfigured information structure to obtain the UE information from the source network element. The UE information is manufacturer-defined UE information which is not added by the current 3gpp protocol.
In this embodiment, a base station pre-configures a set of information structure of additional information, and when a source base station triggers a handover switching-out process, the source base station constructs UE additional information according to the pre-configured information structure, and converts the UE additional information into open type data in an asn.1 code to add to an additional information insertion location. Therefore, when the target base station analyzes the UE additional information, the target base station needs to decode the UE additional information according to the open type, and then analyzes the decoded UE additional information according to the preconfigured information structure to obtain other UE information from the source network element.
The embodiment of the invention can enhance the UE information completeness of the target base station, provide original information for manufacturers to develop various algorithms, and enhance the completeness of different scenes for realizing the algorithms. For example, the access restriction function performed by the base station for the UE user identifier is missing in the handover access scenario in the conventional implementation, and this vacancy can be filled by the present invention. For another example, the invention can transmit the service characteristic analysis result data of the UE at the data application layer of the source base station, so that the target base station directly adopts the operation result data of the source base station, thereby saving the reinitiation operation time and achieving the purpose of improving the service quality of the mobile communication system and the experience degree of the user.
