technical field

The wireless local area network (English: Wireless Local Area Networks, referred to as: WLAN) has the advantage of high-speed data transmission within a certain range, which can make up for the problem that the cellular network cannot efficiently meet the high-speed data service needs of the UE, so it can be used as a supplement and synergy to the current cellular technology. means. Therefore, when the UE is within the network coverage of a wireless local area network access point (English: Wireless Local Area Networks Access Point, WLAN AP for short), the communication network usually ensures that the UE performs data service transmission through the WLAN network as much as possible, And carry out service transmission (such as voice service) through the standard network with the best signal strength.

However, the wireless environment is complex and changeable, and the network coverage of the WLAN AP where the UE is located is often within the network coverage of multiple standard networks (for example, the WLAN coverage is just within the Universal Mobile Telecommunications System (English: Universal Mobile Telecommunications System, referred to as UMTS) network and Long Term Evolution (LTE for short) network). In this case, when the UE transmits data services through the WLAN network, it will switch standard networks according to the signal strength of different standard networks to meet service requirements. For example, when the UE moves to a certain area, if the signal strength of the UMTS network corresponding to this area is stronger than the signal strength of the LTE network, the UE will switch to the UMTE network.

In the process of realizing the handover between the above standard networks, the inventors found that there are at least the following problems in the prior art: because the signal strengths of different standard networks in different areas are different, when the UE moves to a different area in the WLAN network, its The strength of the received standard network signal is also constantly changing, and in order to ensure the service quality of the UE, the network will continuously switch to a network with better signal strength according to the strength of the standard network signal, causing the UE to frequently switch between different standard networks. The inter-network handover between the networks will cause the degradation of UE service quality or even call drop.

detailed description

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.

Nowadays, with the development of network technology, operators usually deploy multiple standard networks at the same time in wireless networks. Therefore, operators cannot easily make a decision to close any standard network, making it an inevitable trend for multiple standard networks to work at the same time. Among them, the above-mentioned standard networks include but are not limited to: second-generation mobile communication technology (English: second generation, referred to as: 2G) global system for mobile communications (English: global system for mobile communications, referred to as: GSM), time division multiple access (English: Time Division Multiple Access, referred to as: TDMA), the third generation of mobile communication technology ( English: 3rd-generation, referred to as: 3G) code division multiple access (English: Code Division Multiple Access, referred to as: CDMA), time division synchronous code division multiple access (English: TimeDivision-Synchronous Code Division Multiple Access, referred to as: TD-SCDMA ), Wideband Code Division Multiple Access (English: Wideband Code Division Multiple Access, referred to as: W-CDMA), Universal Mobile Telecommunications System (English: Universal Mobile Telecommunications System, referred to as: UMTS), high-speed downlink packet access technology (English: High Speed Downlink Packet Access, referred to as: HSDPA), and the long-term evolution of the fourth generation mobile communication technology (English: the 4 Generation mobile communication technology, referred to as: 4G) (English: Long Term Evolution, referred to as: LTE), etc. A wireless local area network (English: Wireless Local Area Networks, WLAN for short) is widely used in a cellular network due to its advantage of being able to transmit high-speed data within a certain range. In this way, the network coverage of WLAN happens to be in the switching area of at least two standard networks at the same time, that is, when the UE is within the network coverage of a certain WLAN AP, it can measure the network parameters of at least two standard networks (eg, signal strength information). The communication network in this scenario usually ensures as much as possible that the UE transmits data services through the WLAN network, and transmits services through the standard network with the best signal strength.

Based on the above description, the embodiments provided by the present invention are applied to a communication network jointly deployed by multiple standard networks and WLAN networks. As shown in FIG. Wireless Local Area Networks Access Point, referred to as WLAN AP) 13. The above-mentioned base stations 11 include a first base station 111 corresponding to the standard network to which the UE 12 is currently connected, and a second base station 112 corresponding to other standard networks (eg, e-NodeB or NodeB). At the same time, in the communication network 1, the UE is in the handover area of at least two standard networks (L1, L2, ..., Ln, n>=2), and the UE can measure each standard of the at least two standard networks The signal strength of the network's base stations. It should be noted that FIG. 1 is an example of two standard networks (the first standard network and the second standard network), which is only an example here. In an actual application scenario, the UE may be in two or at least two standard networks. The switching area of the network.

Embodiment one

Based on the schematic diagram of the communication network shown in FIG. 1, an embodiment of the present invention provides a handover method based on a multi-standard network. On the base station side, as shown in FIG. 2, the method specifically includes the following steps:

201. A base station receives a first measurement report sent by a user equipment UE.

Wherein, the base station in the embodiment of the present invention is the base station corresponding to the standard network to which the UE is currently connected, that is, the above-mentioned first base station. Specifically, when the UE stays within the network coverage of a certain WLAN AP (that is, the target WLAN AP in the present invention) for a long time, the UE reports the network parameters of the WLAN AP to the base station through a measurement report. Wherein, the above-mentioned network parameters include but not limited to: signal strength information of WLAN AP, service set identifier (English: Service SetIdentifier, SSID for short), channel and so on.

202. The base station receives the second measurement report sent by the UE.

Wherein, the above-mentioned second measurement report includes the signal strength information of each standard network in the at least two standard networks measured by the UE. Exemplarily, the signal strength information of the 2G network is usually: Received Signal Strength Indication (English: Received Signal Strength Indication, RSSI for short), and the signal strength information of the 3G network is usually: received signal code power (English: Received Signal Code Power, referred to as: RSCP), the signal strength information of the 4G network is usually: Reference Signal Received Power (English: Reference Signal Receiving Power, referred to as: RSRP). Specifically, the UE can periodically measure the networks of various standards deployed in the area where the UE is located, and form a measurement report to the base station with the measured measurement data of the networks of each standard; When staying within the network coverage of the target WLAN AP, measure the various standard networks deployed in the area where the UE is located, and form a measurement report to the base station with the measured measurement data of each standard network.

Specifically, the UE periodically or aperiodically measures each WLAN AP around the UE and the corresponding base stations of each standard network, and forms a measurement report for the measured measurement data of each WLAN AP and each standard network. to the base station.

203. When the base station determines according to the network parameters of the target WLAN AP that the UE stays within the network coverage of the target WLAN AP for a long time, the base station adjusts the handover threshold corresponding to each standard network according to the signal strength information of each standard network.

Specifically, when the base station determines that the UE will stay in the network of the target WLAN AP for a long time according to the SSID information in the sounding signal (beacon signal) of the WLAN AP in the network parameters of the target WLAN AP sent by the UE When within the coverage area, in order to prevent the UE from frequently performing inter-network handovers between different standard networks, resulting in the degradation of UE service quality or even call drop, the base station will obtain each of the at least two standard networks deployed in the current area where the UE is located. The signal strength information of the standard network, so that the base station can properly adjust the corresponding handover threshold value between each standard network according to the size of the signal strength information of each standard network, so that the UE can reside in the standard network with the largest signal strength information as much as possible In order to reduce the number of inter-network handovers of the UE between networks of various standards.

The aforementioned at least two standard networks include: a first standard network and a second standard network. The above switching threshold value is a switching threshold value triggering standard network switching. Exemplarily, referring to FIG. 1, when the network coverage of the WLAN AP in FIG. 1 is in the handover area of the UMTS network and the LTE network at the same time, if the UE needs to handover from the LTE network to the UMTS network, the UE needs to The measured value M1 obtained after measuring the signal quality of the LTE cell (such as M _RSRP , the reference signal received power of the LTE cell) and the measured value M2 obtained after the UE measures the signal quality of the UMTS cell (such as M _RSCP , UMTS The receiving signal code power of the cell) satisfies the following switching conditions at the same time: M1<L1;M2>L2. Wherein, L1 is the handover threshold of the LTE network, and L2 is the handover threshold of the UMTS network.

Exemplarily, if the first standard network and the second standard network are deployed in the area where the UE is currently located, and the signal strength information of the first standard network is greater than the signal strength information of the second standard network, the base station will increase the second standard network The handover threshold of the network is lowered to lower the handover threshold of the first-standard network, so that the UE stays in the first-standard network as much as possible. Correspondingly, if the first-standard network, second-standard network, and third-standard network are deployed in the area where the UE is currently located, and the signal strength information of the first-standard network is the largest, the base station increases the signal strength of the second-standard network and the third-standard network respectively. The handover threshold of the first-standard network is lowered, so that the UE stays in the first-standard network as much as possible.

204. The base station sends the adjusted handover threshold value of each standard network to the UE, so as to limit the inter-network handover of the UE among the various standard networks.

Specifically, after adjusting the handover threshold value corresponding to each standard network according to the signal strength information of each standard network reported by the UE, the base station sends the adjusted handover threshold value of each standard network to the UE, so that the UE performs inter-network handover according to the adjusted handover threshold of each standard network. Since the base station lowers the handover threshold of the standard network with the largest signal strength information, and increases the handover threshold of other standard networks. The threshold value is switched so that the UE is switched to the standard network with the largest signal strength information as much as possible, that is, the UE is allowed to stay in the standard network with the largest signal strength information as much as possible. It should be noted that after the base station adjusts the switching threshold value of each standard network, it does not modify the switching threshold value of each standard network originally stored in the base station, but only adjusts the switching threshold value of each standard network. The limit value is sent to the corresponding UE, so that the UE can adjust according to the adjusted handover threshold value.

In the multi-mode network-based handover method provided by the embodiment of the present invention, the base station receives the first measurement report containing the network parameters of the target WLAN AP sent by the user equipment after determining that the UE stays within the network coverage of the target WLAN AP for a long time , and receive the second measurement report sent by the UE, and then adjust the handover threshold corresponding to each standard network according to the signal strength information of each standard network in the at least two standard networks measured by the UE in the second measurement report, and Send the adjusted handover threshold value of each standard network to the UE, thereby restricting the inter-network handover of the UE among various standard networks, so that the UE stays in the standard network with a large network coverage as much as possible, thus reducing the number of UEs in the standard network The number of inter-standard network handovers avoids the degradation of user service quality or even call drop due to frequent inter-network handovers between different standard networks by the UE, and saves the power consumption of the UE for handover measurement.

Optionally, as shown in FIG. 3, when the above-mentioned at least two standard networks are the first standard network and the second standard network, step 203 specifically includes the following content:

203a. When the base station determines according to the network parameters of the target WLAN AP that the UE stays within the network coverage of the target WLAN AP for a long time, and the network coverage of the first standard network is greater than the network coverage of the second standard network, the base station sets the first The switching threshold of the standard network is decreased by a second predetermined threshold, and the switching threshold of the second standard network is increased by a second predetermined threshold.

Wherein the second predetermined threshold is set by the base station, and is a reference value for raising or lowering the switching threshold of networks of different standards. The second predetermined threshold is related to specific implementations, and may be set by the base station according to actual conditions, or It may be comprehensively set by the base station with reference to the measurement report reported by the UE to the base station.

Specifically, when the base station adjusts the threshold value of inter-network handover according to the network coverage of different standard networks, the handover threshold value of the standard network with the largest network coverage can be reduced by a second predetermined threshold, while the switching thresholds of other standard networks The limit value is increased by a second predetermined threshold, so that the UE's signal quality measurement value corresponding to the standard network with the largest network coverage is greater than the handover threshold value of the standard network, and the signal quality measurement value corresponding to other standard networks is smaller than its standard network The handover threshold value is set, so that the UE camps on the standard network with the largest signal strength information as much as possible, and reduces the UE's inter-network handover between different standard networks.

Exemplarily, referring to the schematic diagram of a joint deployment scenario of a multi-standard network and a WLAN network shown in FIG. 1, when the network coverage of the WLAN AP in FIG. The specific implementation process of the method provided by the example is as follows, wherein the network coverage of the UMTS network is larger than that of the LTE network.

Specifically, when the base station learns that the UE has stayed within the network coverage of the WLAN AP shown in FIG. drop or even call drop, the base station needs to adjust the handover threshold for the UE to switch between the UMTS network and the LTE network, so that the UE stays on the UMTS network (with large network coverage), and avoids unnecessary network handover by the UE. Wherein, in the prior art, the handover of the UE from the LTE network to the UMTS network needs to meet the following handover conditions at the same time:

M _RSRP <L1;

M _RSCP >L2.

Among them, M _RSRP is the measurement value of the RSRP of the LTE cell obtained by the UE from measuring the LTE cell, M _RSCP is the measurement value of the RSCP of the UMTS cell obtained by the UE from measurement of the UMTS cell, and L1 is the handover threshold of the LTE network , L2 is the handover threshold of the UMTS network.

Specifically, when the base station adjusts the handover threshold for the UE to switch between the UMTS network and the LTE network, since the network coverage of the UMTS network is greater than the network coverage of the LTE network, in order for the UE to access the UMTS network And will not switch to the LTE network, the base station will appropriately increase the handover threshold L1 of the LTE network, and at the same time reduce the handover threshold L2 of the UMTS network. For example, an offset (Offset) (that is, the second predetermined threshold) may be added to the handover threshold. At this time, the handover conditions that the UE needs to meet when handing over from the LTE network to the UMTS network are as follows:

M _RSRP <L1+Offset;

M _RSCP >L2-Offset.

In this way, the M _RSCP can be easily larger than the handover threshold of the UMTS network, and the M _RSRP is easier to be smaller than the handover threshold of the LTE network. The number of switching times. Wherein, the value of the above Offset may be set by the base station according to the actual situation, or may be comprehensively set by the base station with reference to the measurement report reported by the UE to the base station.

Exemplarily, referring to FIG. 1 , if the network coverage of the WLAN AP in FIG. 1 happens to be within the network coverage of the GSM network, the UMTS network and the LTE network at the same time, the network coverage of the GSM network is the largest. Therefore, in order to prevent the UE from frequently performing inter-network handover between networks of different standards while moving, the base station will properly adjust the handover threshold for the UE to switch between networks of different standards, so as to ensure that the UE always stays in the In the GSM network. Specifically, the base station lowers the handover threshold K1 of the GSM network, while increasing the handover thresholds K2 and K3 of the UMTS network and the LTE network. For example, when the UE is currently in the LTE network, the base station needs to adjust the handover condition of the UE from the LTE network to the GSM network in order to ensure that the UE does not perform frequent inter-network handover, that is, Mx<K3;My>K1, adjust Mx<K3+H;My>K1-H. The measurement value Mx (eg, M _RSRP ) obtained by the UE after measuring the signal quality of the LTE cell and the measurement value My (eg, M _RSCP ) obtained by the UE after measuring the signal quality of the GSM cell.

In the multi-mode network-based handover method provided by the embodiment of the present invention, the base station receives the first measurement report containing the network parameters of the target WLAN AP sent by the user equipment after determining that the UE stays within the network coverage of the target WLAN AP for a long time , and receive the second measurement report sent by the UE, and then according to the signal strength information of each standard network in the at least two standard networks measured by the UE in the second measurement report, set the handover threshold corresponding to the standard network with larger signal strength information Lower the value, increase the handover threshold value corresponding to the standard network with small signal strength information, and send the adjusted handover threshold value of each standard network to the UE, thereby limiting the UE's inter-network handover between various standard networks , so that the UE stays in the standard network with a large network coverage as much as possible, thereby reducing the number of UE handovers between standard networks, and avoiding the degradation of user service quality caused by frequent handovers between different standard networks by the UE It even solves the problem of call drop, and at the same time saves the power consumption of the UE for handover measurement.

Based on the schematic diagram of the communication network shown in FIG. 1, the embodiment of the present invention provides another handover method based on a multi-standard network. On the UE side, as shown in FIG. 4, the method specifically includes:

301. When the UE determines that the UE enters the network coverage of the target WLAN AP, the UE records the time the UE stays in the network coverage of the target WLAN AP.

Specifically, the UE periodically or aperiodically measures attribute information of surrounding WLAN APs (such as signal strength information, such as Received Signal Strength (RSS for short), SSID), and according to the measured After receiving attribute information and knowing that it has entered the network coverage of a certain WLAN AP, the UE will start to record the time that the UE stays in the network coverage of the target WLAN AP.

Optionally, step 301 specifically includes the following steps:

301a. When the UE determines that the UE enters the network coverage of the target WLAN AP, the UE starts a timer, and uses the timer to record the time that the UE stays in the network coverage of the target WLAN AP.

Specifically, when the UE enters a certain WLAN AP network, start the timer T and use the timer T to record the time that the UE stays in the network coverage of the WLAN AP. When the preset timing range of the timer is reached, , it is determined that the UE will stay within the network coverage of the target WLAN AP for a long time, and the WLAN AP is used as the target WLAN AP. In addition, the UE will clear the timer in the following scenarios: 1) When the UE leaves the network coverage of the WLAN AP, the UE will stop the timer and clear the timer; 2) when the UE sends the first When reporting the measurement, it means that the UE has completed the timing of the target WLAN AP, and at this time, the timer is cleared.

302. When the dwell time of the UE staying within the network coverage of the target WLAN AP is greater than a first predetermined threshold, the UE acquires network parameters of the target WLAN AP.

Wherein, the above-mentioned first predetermined threshold is preset by the base station, and is used to determine whether the UE stays within the network coverage of the WLAN AP for a long time, and the network parameters of the above-mentioned target WLAN AP include the service of the WLAN AP Set identifies the SSID. The network parameters of the target WLAN AP are used to inform the base station that the UE stays within the network coverage of the target WLAN AP for a long time.

303. The UE measures the signal strength information of each of the at least two standard networks deployed in the area where the UE is located, and sends a second measurement report including the signal strength information of each of the at least two standard networks to the base station.

Specifically, the UE can periodically measure the networks of various standards deployed in the area where the UE is located, and form a measurement report to the base station with the measured measurement data of the networks of each standard; When staying within the network coverage of the target WLAN AP, measure the various standard networks deployed in the area where the UE is located, and form a measurement report to the base station with the measured measurement data of each standard network.

304. The UE sends the first measurement report including the network parameters of the target WLAN AP to the base station, so that the base station determines, according to the network parameters of the target WLAN AP, that the UE stays within the network coverage of the target WLAN AP for a long time, according to at least two standards The signal strength information of each standard network in the network adjusts the handover threshold value corresponding to each standard network, and sends the adjusted handover threshold value of each standard network to the UE, thereby limiting the UE's communication between networks of each standard network switch.

In the handover method based on the multi-standard network provided by the embodiment of the present invention, after the user equipment determines that the UE stays within the network coverage of the target WLAN AP for a long time, it will send the first measurement report containing the network parameters of the target WLAN AP to the base station , and after obtaining the second measurement report sent by the UE, the base station will adjust the switching gate corresponding to each standard network according to the signal strength information of each standard network in at least two standard networks measured by the UE in the second measurement report Limit value, and the adjusted handover threshold value of each standard network is sent to the UE, thereby restricting the inter-network handover of the UE between various standard networks, so that the UE stays in the standard network with a large network coverage as much as possible, thereby Reduces the number of UE handovers between standard networks, avoids the degradation of user service quality or even call drop due to frequent inter-network handoffs between different standard networks, and saves UE power consumption for handover measurement .
