Background technique

Redirection is an important means of implementing service type transfer between systems or within systems. It mainly carries the frequency point of the target network in the radio resource control (Radio Resource Control, RRC) message, so that the user equipment (User Equipment, UE) in After receiving the message, re-initiate service access to the frequency point of the specified target network. Usually, the performance of the entire network coverage directly affects the success rate of UE redirection. In order to improve the success rate of UE redirection and ensure the continuity of services, the Network Management System (NMS) needs to Key Performance Indicators (KPI) (such as redirection success rate and redirection delay) for network optimization to improve the coverage performance of the entire network.

In the prior art, the source network base station and the target network base station respectively count the number of redirection successes, and report the counted number of redirection successes to the NMS device; or the source network base station and the target network base station respectively track, save and report the redirection times Relevant signaling is sent to the NMS device, and the NMS performs calculation or signaling matching to obtain statistical results of redirection success rate and redirection delay, and optimizes the network according to the statistical results.

However, because most current network base stations are limited by various factors such as base station processing performance, network transmission bandwidth, and signaling storage space, base stations can only count KPIs redirected in local areas, making it impossible for NMS to measure the current coverage performance of the entire network. Statistics are not conducive to network optimization.

Embodiment one

Fig. 1 shows a flowchart of a method for reflecting business continuity results and quality provided by an embodiment of the present invention. As shown in Fig. 1, the method may include:

101. The UE records the result and process information when the UE is handed over/redirected from a source network to a target network.

Wherein, the source network may be the network currently accessed by the UE, and the target network may be the network to which the UE is to be handed over/redirected, and the handover/redirection may refer to disconnecting the UE from the source network. Service access is the process of re-initiating service access in the designated target network; the service can be any type of service in the existing network, such as voice service, other services with high quality of service (QoS) requirements, etc.

The result and process information of the handover/redirection may be handover/redirection result and handover/redirection delay information; where the handover/redirection delay information is the network side statistics using the handover/redirection method One of the indicators of target network transfer, the longer the handover/redirection delay, the worse the user experience (QoE) for network services; the handover/redirection delay information may include: handover/redirection delay, handover/redirection The start and end points of the orientation; the start and end points of the handover/redirection delay can be configured to the UE by the source network node, or the start and end points can be reported by the UE when reporting the measurement value; preferably, the handover/redirection The starting point may be the moment when the target network receives the service request initiated by the UE, and the end point of the handover/redirection may be the end time when the UE sends the first service packet on the target network; the handover/redirection result may be the handover/redirection There are two results: successful redirection and handover/redirection failure. Successful handover/redirection means that the UE establishes a connection with the target network and can initiate services in the target network. For example, the UE is released from the source network and connected to the target network After a certain period of time, it is considered that the handover/redirection is successful; if the handover/redirection fails, it means that the UE failed to establish a connection with the target network and cannot initiate services in the target network;

Optionally, the UE may record any of the following situations (1)(2)(3)(4)(5) as handover/redirection failure:

(1) When the UE does not receive the handover/redirection command sent by the source network node, the UE has experienced radio link failure (Radio Link Failure, RLF).

(2) After receiving the switching/redirection command sent by the source network node, the UE is released from the source network, and fails when initiating a random access channel (Random Access Channel, RACH) to the target network.

(3) After receiving the handover/redirection command sent by the source network node, the UE is released from the source network and successfully initiates RACH to the target network, but When sending a radio resource control (Radio Resource Control, RRC) connection establishment request, it is rejected by the network node of the target network with a preset reason.

Wherein, the preset reason is preset by the network node of the target network as required, and may include: load control, no contract between the UE and the network node of the target network, and the like.

(4) After receiving the handover/redirection command sent by the source network node, the UE is released from the source network, and successfully initiates RACH access to the target network, but is rejected when sending a service request to the network node of the target network Rejected by the network node of the target network.

(5) After receiving the switching/redirection command sent by the source network node, the UE is released from the source network, and successfully initiates RACH access to the target network, but within the preset time, the UE is in the target network Call dropped.

Wherein, the handover/redirection command is used to instruct the UE to perform handover/redirection; the preset time can be set according to needs, which is not limited in this embodiment of the present invention.

Optionally, in this embodiment of the present invention, when the recorded handover/redirection result is handover/redirection failure, the UE also needs to record the failure reason corresponding to the current handover/redirection failure, for example, the above-mentioned (2) The reason for the failure in the above case is: the RACH access failure of the target network; the failure reason in the above case (3) is: the RRC connection request rejection of the target network; the failure reason in the above case (4) is: the target network The service request is rejected; the failure reason in the case of (5) above is: the call is dropped in the target network.

102. The UE reports the recorded handover/redirection result and process information to the network node.

Wherein, the network node may be a device that controls the entire network in the network, such as a base station, an evolved base station (Evolved EodeB, eNodeB), a radio network controller (Radio Network Controller, RNC), a core network node, an operation and maintenance node, etc. ;

In this embodiment of the present invention, the network node may be a network node of the source network, a network node of the target network, or a network node of a third network, where the third network is the The UE selects after handover/redirection failure A network different from the source network and the target network.

Optionally, the UE may report the recorded handover/redirection result and process information in any of the following ways (1)(2)(3):

(1) When the network node is a network node of the source network, the UE reports the recorded handover/redirection result and process information to the network node, specifically including:

The UE stores the result and process information of the handover/redirection, and reports the recorded handover/redirection to a network node of the source network in the source network after the UE reconnects to the source network. Redirected result and process information.

For example, the UE may store the measured handover/redirection result and process information for 48 hours, and report the stored handover/redirection result and process information on the source network when the UE returns to the source network within these 48 hours.

(2) When the network node is a network node of the target network, the UE reports the recorded handover/redirection result and process information to the network node, specifically including:

The UE reports the handover/redirection result and process information to the network node of the target network, and the network node of the target network forwards it to the network node of the source network through an inter-network interface, and the source network The network node of the network performs corresponding processing according to the result of the handover/redirection and the process information; or,

The UE directly reports the handover/redirection result and process information to a network node of the target network in the target network, and the network node of the target network performs the handover/redirection result and process information according to the handover/redirection result and process information Treat accordingly.

(3) When the network node is a network node of the third network, the UE reports the recorded handover/redirection result and process information to the network node, specifically including:

The UE reports the handover/redirection result and process information to the network node of the third network, and the network node of the third network forwards it to the network node of the source network through an inter-network interface; or,

The UE directly reports the handover/redirection result and process information to the network node of the third network, and the network node of the third network according to the handover/redirection The redirected results and process information are processed accordingly.

Wherein, the corresponding processing may refer to: the network node performs processing such as network optimization according to the handover/redirection result and process information.

Optionally, in this embodiment of the present invention, the UE also needs to trigger the execution of the above method according to a command issued by the source network node or its own configuration. Specifically, before step 301, the method may also include:

The UE receives first radio resource control (Radio Resource Control, RRC) signaling sent by the source network node; wherein, the first RRC signaling determines that the UE performs handover/redirection at the source network node included in the handover/redirection command or sent before the source network node determines that the UE performs handover/redirection; the first RRC signaling is used to command the UE to switch/redirect from the source network to the target network record and report the handover/redirection result and process information, and indicate the manner of reporting the handover/redirection result and process information; the handover/redirection command is used to instruct the UE to perform handover/redirection; or,

The UE records the handover/redirection result and process information by default when the UE is handover/redirection, and reports the handover/redirection result and process information to the network node.

Optionally, in order to make more use of the evaluation of the overall network coverage performance by the source network node, in the embodiment of the present invention, the UE also needs to record some other additional information such as the measurement time and the location information of the UE during the measurement, and send it to The source network node reports these additional information.

In this way, the UE records the handover/redirection result and process information during the handover/redirection process and reports it to the network side node, so that the network node collects the measurement information of the whole area that cannot be performed by the traditional drive test according to the information reported by the UE, so , the network coverage performance can be evaluated more objectively, which is beneficial to further optimize the network.

Further, in the embodiment of the present invention, in addition to collecting relevant measurement information of the wireless access layer such as handover/redirection results and handover/redirection delay information, in order to make the network optimized by the network side node closer to user experience , to bring higher satisfaction to the user.
