Description

A method for processing measurement configuration information in an LTE network and a base station

technical field

The present invention relates to the technical field of wireless communication, in particular to a method for processing measurement configuration information in an LTE network and a base station.

Background technique

The measurement in the LTE network mainly refers to the mobility measurement in the connected state. The LTE network notifies the UE (User Equipment, user equipment) of the measurement configuration through a measurement configuration message (RRC Connection Reconfiguration), and the UE will measure the current serving cell, and judge whether to Neighboring cell measurements need to be performed. When the measurement report condition is satisfied, the UE sends the measurement result to the base station eNB through a measurement report message.

Currently, there are 7 measurement events in the live LTE network. For the different system, more attention is paid to A1, A2, B1, B2 events; for the LTE native system, more attention is paid to A1, A2, A3, A4, A5 events. In the LTE live network, the first measurement configuration message is usually issued for A1, A3, A2 events. If the A3 event is met, the same frequency handover can be performed. After the A2 event is met, other measurement events will be triggered, such as A5, B2, etc. , meeting the measurement event A5 or B2 triggers inter-frequency handover or redirection. Among them, the A1 event indicates that the current serving cell is better than the absolute threshold, which is used to close the inter-frequency/different system measurement; the A2 event indicates that the current serving cell is worse than the absolute threshold, and is used to enable the inter-frequency/different system measurement; A3 event indicates that the neighboring cell is good The serving cell has a certain offset; the A4 event indicates that the neighboring cell is better than the absolute threshold, which can be used for load sharing; the A5 event indicates that the current serving cell is worse than the absolute threshold 1, and the neighboring cell is better than the absolute threshold 2; the B1 event indicates that the neighboring cell of the different system is better The B2 event indicates that the current serving cell is worse than the absolute threshold 1, and the neighbor cell of a different system is better than the absolute threshold 2. The UE performs measurement according to the measurement configuration issued by the network, and evaluates the measurement report when a certain trigger event is met. If the reporting condition is met, the UE fills in the measurement result and sends it to the network through a measurement report.

In the current LTE network, the mobility of UEs in the connected state adopts handover in the LTE network, that is, same-frequency handover and inter-frequency handover, while for different systems, redirection is used, including measurement-based redirection and blind redirection . Wherein, blind redirection means that no measurement is required, and the LTE network specifies a redirection frequency point for the UE. In terms of network, it supports measurement-based redirection and blind redirection. In terms of mobile phones, for different wireless access systems, such as GSM systems, it can be divided into two types that support Geran measurement and those that do not support Geran measurement. From the above analysis, it can be seen that the mobile phone based on Geran measurement needs to select the frequency point for inter-system redirection by measuring according to the GSM frequency point list in the B2 event sent by the RRC signaling containing the measurement configuration information.

Taking the GERAN system as an example, when the GERAN measurement frequency point for measuring configuration information in the LTE network is not within the GERAN frequency band supported by the UE, such as frequency point 125, there will be a large number of high-dropout cells in the LTE network, and the cause of the dropout is basically The UE for radio connection is lost (Radio connection with ue lost), and the signaling points triggered by the loss are all concentrated in the RSRP (Reference Signal Received Power, reference signal received power) of the current serving cell is lower than -105dBm (A2 in LTE network The RSRP threshold set by the event) after the A2 event is triggered. Specifically, the base station sends RRC signaling including measurement configuration information to the UE in the connected state, and then the UE does not respond and goes offline. The above disconnection process is described by signaling as follows:

In the measurement report reported by the UE, the RSRP of the current serving cell of the UE is -109dBm, which is already lower than the RSRP threshold value -105dBm set by the A2 event, thus triggering the A2 event. Subsequently, the base station sends RRC signaling including measurement configuration information to the UE in the connected state, and the ARFCN of the GERAN system in the measurement configuration information includes frequency point 125. However, this frequency point is not a frequency point in the GERAN frequency band supported by the UE, and then the base station sends a UE context release request message to the MME (Mobility Management Entity, mobility management entity), and the UE goes offline. In addition, according to signaling statistics, UEs that are offline all support GERAN frequency measurement (the 23rd bit of the functional group index is 1). For UEs that do not support GERAN frequency measurement, there is no above dropped connection problem.

Through the above analysis, the applicant of this application found that for a UE that supports GERAN frequency measurement, if the frequency point of the GERAN frequency band that the UE does not support is configured in the measurement configuration information of the LTE network, the disconnection phenomenon will occur, and the user needs to re-initiate the PS business. In the weak coverage area lower than the RSRP threshold set by the A2 event, this phenomenon will be very frequent, seriously affecting customer perception. In addition, with the continuous advancement of VoLTE, UEs supporting GERAN frequency measurement will occupy a dominant position, which aggravates the impact of this problem.

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Some of the words mentioned in the embodiments of the present invention are illustrated below.

The user equipment (User Equipment, UE for short) mentioned in the embodiment of the present invention refers to equipment such as a mobile terminal or a personal computer (Personal Computer, PC for short) used. Examples include smartphones, personal digital assistants (PDAs), tablets, laptops, carputers, handheld game consoles, smart glasses, smart watches, wearable devices, virtual display devices, or display enhancements such as Google Glass, Oculus Rift, Hololens, Gear VR), etc.

Fig. 1 is a flowchart of a method for processing measurement configuration information in an LTE network provided by an embodiment of the present invention. As shown in FIG. 1, a method for processing measurement configuration information in an LTE network provided by an embodiment of the present invention includes:

In step S101, after the user equipment UE connected to the base station triggers the A2 event, the base station checks whether it has stored the radio access capability information of the UE.

Among them, the A2 event indicates that the RSRP of the current cell measured by the UE is less than the preset RSRP threshold value, which is used to enable inter-frequency/inter-system measurement. This event can reflect that the current cell is a weak network coverage area. The wireless access capability information includes whether the UE supports frequency measurement of different frequencies and/or different systems and/or information about whether the UE supports access to frequency bands of the different frequencies and/or different systems. The different system refers to a system different from LTE.

Specifically, before the UE triggers the A2 event, the method further includes: when the UE initially accesses the LTE network, the base station receives the initial context sent by the mobility management entity MME in the LTE network An establishment request message, and obtain the radio access capability information of the UE according to the initial context establishment request message, and store the radio access capability information.

For example, when the mobile phone initially accesses the LTE network, the feature group indicator (feature group indicator) field in the initial context setup request message (Initial Context Setup Request) sent by the MME to the base station describes whether the mobile phone supports different frequency and /or the measurement of different systems (32 bits in total), such as the 23rd bit, indicates whether the mobile phone supports the frequency measurement function of the GERAN system, 1 means support, and 0 means no support. If the frequency measurement function of the GERAN system is supported, event B2 is reported for measurement in the E-UTRA connection mode. The frequency band information of the GERAN system appearing in the network protocol mainly includes: gsm450, gsm480, gsm710, gsm750, gsm810, gsm850, gsm900P, gsm900E, gsm900R, gsm1800, gsm1900. When the mobile phone initially accesses the LTE network, the initial context establishment request message sent by the MME to the base station also includes a UE wireless capability message, which includes E-UTRA, GERAN, and CDMA2000-1xRTT supported by the mobile phone. and other system frequency band information. Through this information, the base station can confirm all frequency band information of different frequencies and/or different systems supported by the accessed mobile phone. The protocol stipulates that the UE wireless capability message is an optional field in this message, but the base station can also send the UE capability inquiry message (UE Capability Enquiry) to the UE through RRC signaling, and the UE replies with the UE capability information (UE Capabiltiy Information), thereby Obtain frequency bands of all inter-frequency and/or inter-system supported by the mobile phone.

Next, in step S102, when the base station checks that it has stored the radio access capability information, the base station judges whether the UE supports the radio access capability information in the measurement configuration information according to the radio access capability information. Inter-frequency and/or inter-system frequency measurements.

Specifically, the method further includes: when the base station checks that it does not store the radio access capability information, the base station sends a UE capability query message to the UE through RRC signaling, so that the The UE replies with a UE capability message, so as to obtain the radio access capability information of the UE.

Fig. 2 is a flowchart of signaling interaction between a base station and a UE according to an embodiment of the present invention. As shown in Figure 2, if the base station checks that it does not store radio access capability information, the base station sends a UE capability query message to the UE through RRC signaling, and the UE replies with a UE capability message to the base station, so that the base station can obtain the information based on the UE capability message. UE radio access capability information.

Then, in step S103, when it is judged that the UE supports frequency measurement of different frequencies and/or different systems in the measurement configuration information, the base station uses the different frequency and/or different system frequency measurements in the measurement configuration information The different-system measurement frequency point is matched with the frequency band information that the UE supports to access the different-frequency and/or different-system, and a matching result is obtained.

Specifically, the base station compares the frequency band information corresponding to the different frequency and/or different system measurement frequency points in the measurement configuration information with the frequency band information that the UE supports access to the different frequency and/or different system Yes, if the UE supports access to the different frequency and/or different system frequency band information corresponding to the different frequency and/or different system measurement frequency point, then the different frequency and/or different system measurement frequency point It belongs to the frequency band where the UE supports access to the different frequency and/or different system, that is to say, the different frequency and/or different system measurement frequency point has been matched with the UE supporting the access to the different frequency and/or different system System frequency band information. If the UE supports access to the frequency band information of the different frequency and/or different system, there is no frequency band information corresponding to the different frequency and/or different system measurement frequency point, then the different frequency and/or different system measurement frequency point does not Belongs to the frequency band where the UE supports access to the different frequency and/or different system, that is, the different frequency and/or different system measurement frequency point does not match the UE supports access to the different frequency and/or different system frequency band information.

Finally, in step S104, the base station filters the measurement frequency points in the measurement configuration information that do not match the frequency band information according to the matching result, and sends the measurement configuration information to the UE, so that all The UE performs frequency measurement of the inter-frequency and/or inter-system.

Specifically, the base station sends the measurement configuration information to the UE through RRC signaling including the measurement configuration information, so that the UE performs frequency measurement of the inter-frequency and/or inter-system.

Preferably, the inter-frequency and/or inter-system includes at least one of the following: E-UTRAN, GERAN, CDMA2000-1xRTT and UTRAN. Specifically, when the UE supports frequency measurement of different frequencies and/or different systems such as E-UTRAN, GERAN, CDMA2000-1xRTT or UTRAN, the base station may also include the E-UTRAN, GERAN, CDMA2000-1xRTT or The measurement frequency points of different frequencies and/or different systems such as UTRAN are matched with the frequency band information of different frequencies and/or different systems such as E-UTRAN, GERAN, CDMA2000-1xRTT or UTRAN supported by the UE to obtain matching results , and filter the measurement frequency points in the measurement configuration information that do not match the corresponding frequency band information according to the matching result, and send the measurement configuration information to the UE, so that the UE performs frequency measurement of different frequencies and/or different systems, and improves network performance. At the same time, it improves customer perception and has high innovation value and practical value.

In this embodiment, after the user equipment UE connected to the base station triggers the A2 event, the base station obtains the wireless access capability information of the UE, and the wireless access capability information includes whether the UE supports different frequencies and/or or the frequency measurement of different systems and/or the UE supports access to the frequency band information of the different frequencies and/or different systems, and judge whether the UE supports the information in the measurement configuration information according to the wireless access capability information Inter-frequency and/or inter-system frequency measurement, when it is judged that the UE supports inter-frequency and/or inter-system frequency measurement in the measurement configuration information, the base station sets the inter-frequency and/or inter-system frequency measurement in the measurement configuration information Frequency and/or different system measurement frequency point is matched with the frequency band information that the UE supports to access the different frequency and/or different system to obtain a matching result, and then the base station filters the measurement configuration according to the matching result The measurement frequency points in the information that do not match the frequency band information, and send the measurement configuration information to the UE, so that the UE can perform the frequency measurement of the different frequency and/or different system, avoiding the Inter-frequency and/or inter-system measurement frequency points in the measurement configuration information do not match the frequency band information that the UE supports to access inter-frequency and/or inter-system, resulting in UE disconnection problems, improving network performance and improving customer perception , has high innovation value and practical value.

Fig. 3 is a flowchart of a method for processing measurement configuration information in an LTE network when the foreign system is a GERAN system. As shown in Figure 3, when the foreign system is a GERAN system, the processing method of measurement configuration information in the LTE network includes:

In step S201, it is judged whether the RSRP of the current serving cell measured by the UE is lower than the RSRP threshold value set by the A2 event.

Wherein, the UE is a mobile phone, if it is judged that the RSRP of the current serving cell measured by the UE is lower than the RSRP threshold value set by the A2 event, that is, the mobile phone triggers the A2 event, enter step S202, otherwise end the process.

Next, in step S202, the base station connected to the UE checks whether it has stored the wireless access capability of the UE.

Wherein, the wireless access capability of the mobile phone includes whether the mobile phone supports frequency measurement of the GERAN system and the frequency band information that the mobile phone supports access to the GERAN system. If the base station has stored the wireless access capability information, go to step S204, otherwise go to step S203.

In step S203, the base station sends a UE capability query message to the UE, so that the UE replies with UE capability information, so as to obtain wireless access capability information of the UE.

Specifically, a message is sent from the eNB to the UE to obtain the capability information of the mobile phone through an existing signaling process stipulated in the 3GPP protocol. The purpose of this step is to ensure that the eNB obtains the UE's capability information including: (1) whether it supports the frequency measurement of the GERAN system; (2) the mobile phone supports the frequency band of the GERAN system.

In step S204, the base station filters out the frequency points of the frequency band of the GERAN system not supported by the UE, and then delivers the GERAN measurement frequency point list.

Wherein, the measurement configuration information includes a list of GERAN measurement frequency points, and the measurement configuration information is sent to the mobile phone through RRC signaling including the measurement configuration information, so that the mobile phone performs frequency measurement of the GERAN system.

Fig. 4 is a flowchart of a method for filtering measurement frequency points of different systems in measurement configuration information provided by an embodiment of the present invention. As shown in FIG. 4 , the above step S204 specifically includes: first determining whether the UE supports the frequency measurement of the GERAN system, and setting the parameter i equal to 1 if the UE supports the frequency measurement of the GERAN system. Then, the base station judges whether the number of measurement frequency points of the GERAN system in the measurement configuration information is greater than the parameter i, and if it is larger, judges whether the frequency point Ei in the network configuration information belongs to the GERAN frequency band supported by the UE, and if so, stores the frequency point Ei in the preparation In the GERAN measurement frequency point list sent, if not, delete the frequency point Ei. Afterwards, the parameter i is increased by 1, and the above process of cyclic judgment is repeated until all the frequency points in the measurement configuration information are judged. Finally, the GERAN measurement frequency point list to be delivered is delivered to the UE for measurement through RRC signaling.

It should be noted that the method for processing measurement configuration information in the LTE network provided by the present invention is also applicable to the same system, E-UTRAN. Wherein, the same system refers to being in the same system as the LTE. Take E-UTRAN as an example for the following description. When the user equipment UE connected to the base station triggers the A2 event and then triggers the A3 event or the A5 event, the measurement configuration information needs to be processed. Specifically, the base station obtains the radio access capability information of the UE, and the radio access capability information includes whether the UE supports inter-frequency measurement of the E-UTRAN system and whether the UE supports access to the E-UTRAN system. The frequency band information of the UTRAN system, and judge whether the UE supports the inter-frequency measurement of the E-UTRAN system according to the wireless access capability information, and if it is judged that the UE supports the inter-frequency measurement of the E-UTRAN system, the The base station matches the E-UTRAN system measurement frequency point in the measurement configuration information with the frequency band information that the UE supports to access the E-UTRAN system to obtain a matching result, and then, the base station filters according to the matching result In the measurement configuration information, the E-UTRAN system measures frequency points that do not match the frequency band information, and sends the measurement configuration information to the UE, so that the UE performs the inter-frequency of the E-UTRAN system measure, and decide whether the UE performs intra-system inter-frequency handover according to the measurement results returned by the UE. In this way, the problem of UE disconnection caused by the mismatch between the E-UTRAN system measurement frequency point in the network measurement configuration information and the frequency band information that the UE supports to access the E-UTRAN system is avoided, and the network performance is improved while improving customer service. Perception has high innovation value and practical value.
