Background
In the current communication network, network registration of the ue, cell access, cell reselection, and cell handover are all based on network control, that is, the ue performs based on rules on the network side. Specifically, when accessing a cell, the ue selects a cell camping access with a best Reference Signal Receiving Power (RSRP), completes network registration in the cell, and transmits a service in the cell.
The user equipment registering to the network side and the service transmission based on the network side mainly comprise two processes, wherein the first process is as follows: establishing a signaling plane; the second is that: and establishing a user plane. As long as the signaling plane is established normally, the cell will be in an active state, and the ue can detect RSRP of the cell and camp on the cell with the best RSRP. However, if the user plane of the cell fails, the ue cannot transmit the service in the cell, for example, the base station managing the cell is different from the routes or ports configured at both ends of the core network, that is, the user plane between the base station and the core network fails, which may cause the service request of the ue to fail. However, since the signaling plane of the cell is normal, if the user equipment detects that the RSRP of the cell is the best, the user equipment always stays in the cell, so that the service of the user is always in a failure state, which affects the user experience.
Therefore, when the signaling plane of the cell is normal and the user plane fails, how to quickly recover the service by the user equipment and improvement of the user experience are problems to be solved at present.

It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments.
First, it should be understood that the user device in the present application may include a smart Phone (e.g., an Android Phone, an iOS Phone, a Windows Phone, etc.), a tablet computer, a palm computer, a notebook computer, a Mobile InTerneT device MID (Mobile InTerneT Devices, abbreviated as MID), a wearable device, or the like.

The access network equipment of the application is explained and illustrated by the base station in a unified way, and repeated explanation is not needed.
Referring to fig. 1, fig. 1 is an architecture diagram of a communication system according to an embodiment of the present disclosure. The communication system comprises a user equipment 10, an access network equipment 20 and an access network equipment 30. The access network device 20 manages a cell a, and the access network device manages a cell B, where the cell a and the cell B are two cells of a plurality of cells where the user equipment 10 is located, and the reference signal received power of the cell a is the largest among the plurality of cells, and the cell B is the second largest.
For example, when the user equipment 10 performs network registration, first, a cell is selected, and it is determined that the reference signal received power of the cell a is the largest among the multiple cells; therefore, the user equipment 10 selects the cell a to access, performs network registration in the cell a, and performs a communication service in the cell a after the network registration is completed. When the network registration of the user equipment 10 in the cell a is still successful (i.e. there is still network signal in the cell a, that is, the reference signal received power of the cell a can still be measured at this time), but when the number of continuous failures of the communication service in the cell a is greater than the threshold value, the cell reselection is started, and the cell B access is selected in the cell reselection, and then the communication service is performed in the cell B to recover the communication service.
It can be seen that, in this embodiment, when the signaling plane of the cell where the user equipment is currently performing the service is normal, but the user plane is faulty, the communication service of the user may continuously fault, and for this situation, the user equipment may actively perform cell reselection, select the cell B whose reference signal received power is next to that of the cell a to access, and perform the communication service of the user in the cell B, thereby avoiding the problem of the fault of the user plane of the cell a, quickly recovering the communication service of the user, and improving the user experience.
Fig. 2 is a flowchart illustrating a service recovery method according to an embodiment of the present application. The method is applied to the communication system. The method comprises the following steps:
201: the user equipment measures a reference signal received power of each of a plurality of cells.
The plurality of cells are cells where the user equipment is located.
For example, when the ue performs cell handover or is powered on, it performs cell search, measures the reference signal received power of each of the multiple cells, and selects the cell with the best reference signal received power for camping.
202: the user equipment accesses to a cell A according to the reference signal received power of each cell, wherein the cell A is a cell with the maximum reference signal received power in a plurality of cells.
Illustratively, when the ue measures the reference signal received power of cell a, which is the largest of the plurality of cells, the ue shall camp on cell a, access cell a, and complete network registration in cell a.
Specifically, the user equipment completes synchronization of uplink resources through random access and an access network device a (base station) managing the cell a, and sends network registration information to the access network device a, and the access network device sends the network registration information to the core network, thereby completing network registration in the user equipment cell a. Further, after the cell a completes network registration, the ue completes establishment of a signaling plane and a user plane with the access network device a and the core network. After the establishment of the signaling plane and the user plane is completed, the ue may perform transmission of communication service in cell a.
203: and when the network registration of the user equipment in the cell A is successful and the continuous failure times of the communication service in the cell A are greater than a threshold value, starting cell reselection, and accessing to a cell B to perform the communication service in the cell B, wherein the cell B is a cell in which the reference signal receiving power in the plurality of cells is second to the cell A only.
The communication service includes a voice service, a call service, a video service, a live broadcast service, and so on. The present application does not limit the type of communication service.
It should be noted that, in the process of performing communication service transmission in the cell a, if the user plane of the cell a fails at a certain time, but the signaling plane is normal, the communication service in the cell a cannot be performed. Since the signaling plane of the cell a is normal, the cell a is still in an active state, at this time, the ue can still search for the signal of the cell a, and the network displayed in the cell a is normal. Therefore, the user equipment still stays in cell a and retransmits the communication traffic. It should be appreciated that the communication service of the user equipment within cell a may continue to fail before the failure of the user plane of cell a is recovered.
In view of the above situation, in the process of performing a communication service in a cell a in the present application, when a user equipment detects that a number of consecutive failures of the communication service in the cell a is greater than a threshold and a network registration displayed by the user equipment in the cell a is successful (i.e., a signal of the cell a can be searched), the user equipment determines that a signaling plane of the cell a is normal but a user plane is faulty, at this time, the user equipment automatically starts cell reselection, selects a cell B to access (a cell with the best reference signal receiving power cannot be accessed), completes the network registration in the cell B, reestablishes the signaling plane and the user plane in the cell B, and performs transmission of the communication service in the cell B, thereby recovering the communication service of the user.
In an embodiment of the present application, the user equipment may determine, through the signaling point, the number of times of continuous failure of the communication service in the cell a. For a communication service, there is a corresponding service Request signaling point (server Request MSG), and for the service Request signaling point, if the communication service is successfully executed, a corresponding service establishment success signaling point (Active EPS bearer context accept) is generated. Therefore, for the communication service, a service request signaling point of the communication service is acquired, if a service establishment success signaling point corresponding to the service request signaling point is acquired, it is determined that the communication service is successfully executed, and if a service establishment success signaling point corresponding to the service request signaling point is not acquired, it is determined that the communication service is unsuccessfully executed. For example, the service request signaling point includes: radio Bearer ID: a1, freq: a2, SFN: a3; radio Bearer ID: b1, freq: b2, SFN: b3; radio Bearer ID: c1, freq: c2, SFN: c3. The signaling point with successful service establishment comprises the following steps: radio Bearer ID: a1, freq: a2, SFN: a3; radio Bearer ID: b1, freq: b2, SFN: b3. Based on the two signaling points, the service execution corresponding to the signaling points Radio Bearer ID: c1, freq: c2, SFN: c3 fails. After the communication service execution failure is determined for the first time, the user equipment retries the communication service within the next preset time, and obtains whether to generate a corresponding service establishment success signaling point or not for each retry, determines the continuous failure times of the communication service within the preset time based on whether to generate the corresponding service establishment success signaling point or not, and takes the continuous failure times as the continuous failure times of the communication service within the cell A.
It can be seen that, in this embodiment, when the signaling plane of the cell where the user equipment is currently performing the service is normal, but the user plane is faulty, the communication service of the user may continuously fault, and for this situation, the user equipment may actively perform cell reselection, select the cell B whose reference signal received power is next to that of the cell a to access, and perform the communication service of the user in the cell B, thereby avoiding the problem of the fault of the user plane of the cell a, quickly recovering the communication service of the user, and improving the user experience.
Referring to fig. 3, fig. 3 is a schematic flowchart of another service recovery method according to an embodiment of the present application. This implementation is the same as the embodiment shown in fig. 2 and will not be described again here. The method is applied to the communication system. The method comprises the following steps:
301: the user equipment measures a reference signal received power of each of a plurality of cells.
302: the user equipment accesses to a cell A according to the reference signal received power of each cell, wherein the cell A is a cell with the maximum reference signal received power in a plurality of cells.
303: and when the network registration of the user equipment in the cell A is successful and the continuous failure times of the communication service in the cell A are greater than a threshold value, the user equipment adds the physical cell identifier of the cell A into a cell forbidden list.
The cell barred list is used for indicating that the user equipment ignores the cell corresponding to each physical cell identifier in the cell barred list when the user equipment reselects the cell.
Illustratively, when the user equipment determines that the network registration in the cell a is successful, but the number of continuous failures of the communication service in the cell a is greater than the threshold, that is, it is determined that the user plane of the cell a is faulty, and the signaling plane is normal, the user equipment adds the physical identifier of the cell a to the cell forbidden list, so as to ignore the cell a during cell reselection.
It should be noted that adding the Physical Cell Identity (PCI) of the Cell a to the forbidden list is only an example, and in practical applications, the frequency point of the Cell or other identification information with a unique identification function may also be added to the forbidden list, so that the Cell corresponding to the identification information is ignored by the identification information of the Cell when the Cell is reselected.
304: and in the process of cell reselection, the user equipment responds to the cell forbidden list, ignores the cell A and determines the cell B as a cell with the maximum reference signal receiving power in other cells except the cell A.
For example, after constructing the cell barring list, the user equipment may traverse each PCI in the barring cell list during cell reselection, and then ignore a cell corresponding to each PCI in the cell reselection process, because the cell barring list includes the PCI of the cell a. Therefore, cell a is ignored in response to the cell barred list during cell reselection.
In this application, the neglecting of the cell a by the user equipment includes the following two cases:
in the first case: the user equipment responds to the cell forbidden list, and only measures the reference signal received power of other cells except the cell A in the plurality of cells in the cell reselection process, namely the user equipment directly ignores the cell A and does not measure the reference signal received power of the cell A, so that the cell reselection is only carried out in other cells. When the reference signal received power of the cell B in the other cells is determined to be the best, the cell B is accessed.
In the second case: during cell reselection, the ue may measure the received power of the reference signal of each of the multiple cells (i.e., change the procedure of cell measurement). The ue then ignores the reference signal received power of cell a in response to the cell barring list, such that the ue will access cell B when it is determined that the reference signal received power of cell B is the best among the remaining reference signal received powers.
305: and the user equipment accesses the cell B in response to the cell B being the cell with the maximum reference signal receiving power in other cells except the cell A.
For example, since the user equipment ignores the cell a, the cell a is not considered in the cell reselection process. When the cell B is determined to be the cell with the maximum reference signal receiving power in other cells except the cell A, the user equipment can automatically access the cell B to complete the reselection of the cell.
It should be noted that after the ue accesses the cell B, the communication service is resumed in the cell B.
It can be seen that, in this embodiment, when the signaling plane of the cell where the user equipment is currently performing the service is normal, but the user plane is faulty, the communication service of the user may continue to be faulty, and for this situation, the user equipment adds the PCI of the cell a to the cell forbidden list before performing the cell reselection, so that the cell a may be ignored in the cell reselection process, and thus the cell a may be avoided, and selects the cell B whose reference signal receiving power is next to the cell a for access, and performs the communication service of the user in the cell B, thereby avoiding the problem of the fault of the user plane of the cell a, recovering the communication service of the user quickly, and improving the user experience.
Referring to fig. 4, fig. 4 is a schematic flowchart of another service recovery method according to an embodiment of the present application. This implementation is the same as in the embodiment shown in fig. 2 and 3 and will not be described again here. The method is applied to the communication system. The method comprises the following steps:
401: the user equipment measures a reference signal received power of each of a plurality of cells.
402: the user equipment accesses to a cell A according to the reference signal received power of each cell, wherein the cell A is a cell with the maximum reference signal received power in a plurality of cells.
403: and when the network registration of the user equipment in the cell A is successful and the continuous failure times of the communication service in the cell A are greater than a threshold value, the user equipment adds the physical cell identifier of the cell A into a cell forbidden list.
Optionally, the cell barring list is used to indicate that the user equipment ignores a cell corresponding to each physical cell identifier in the cell barring list when performing cell reselection.
Optionally, the cell barring list is further configured to instruct the user equipment to ignore a cell corresponding to each physical cell identifier in the cell barring list when performing cell measurement.
404: and in the process of cell reselection, the user equipment responds to the cell forbidden list, ignores the cell A and determines the cell B as a cell with the maximum reference signal receiving power in other cells except the cell A.
For an exemplary procedure of cell reselection performed by the ue, reference may be made to what is described in fig. 4, and a description thereof is not repeated.
405: and the user equipment accesses the cell B in response to the cell B being the cell with the maximum reference signal receiving power in other cells except the cell A.
406: the user equipment receives a cell measurement message from an access network device managing said cell B.
It should be noted that after the user equipment accesses to cell B, the access network equipment of cell B may send a cell measurement message to the user equipment, so as to determine whether there is a better quality cell in neighboring cells of cell B, so as to perform cell handover. Accordingly, after receiving the cell measurement message, the ue performs cell measurement.
407: and the user equipment responds to the cell forbidden list and the cell measurement message, ignores the cell A in the process of cell measurement, and generates a measurement report, wherein the measurement report does not contain the measurement result of the cell A.
Wherein, ignoring cell a in the cell measurement process includes the following two cases:
in the first case: and the user equipment responds to the cell measurement message, performs cell measurement on each cell in the plurality of cells and generates a measurement report of each cell. The user equipment then determines the forbidden list of cells in response to the forbidden list of cells
The PCI containing the cell A filters the measurement result of the cell A to generate a final measurement report, and then the final measurement is carried out
The report includes only the measurement report of cell B.
In the second case: the user equipment responds to the cell forbidden list and determines that the cell forbidden list contains the PCI of the cell A, so that when responding to the cell measurement message to carry out cell measurement, only other cells except the cell A in the plurality of cells are measured, the measurement results of the other cells are generated, and then the measurement report is obtained.
408: and the user equipment sends the measurement report to the access network equipment so that the user equipment continues to reside in the cell B.
It can be understood that, since the measurement report does not include the measurement result of the cell a, the access network device determines that the cell B is still the cell with the best quality currently, and the access network device does not instruct the user equipment to switch to other cells. Accordingly, the user equipment may continue to camp on cell B.
It can be seen that, in this embodiment, when the signaling plane of the cell where the user equipment is currently performing the service is normal, but the user plane is faulty, the communication service of the user may continue to be faulty, and for this situation, the user equipment adds the PCI of the cell a to the cell forbidden list before performing the cell reselection, so that the cell a may be ignored in the cell reselection process, and thus the cell a may be avoided, and selects the cell B whose reference signal receiving power is next to the cell a for access, and performs the communication service of the user in the cell B, thereby avoiding the problem of the fault of the user plane of the cell a, recovering the communication service of the user quickly, and improving the user experience. Moreover, the PCI of the cell is added into the cell forbidden list, so that the user equipment is prevented from being switched back to the cell A after being accessed to the cell B, and the user equipment can be ensured to normally carry out communication service in the cell B.
In an embodiment of the present application, when adding the physical cell identifier of the cell a to the cell barred list, setting an effective duration of adding the physical cell identifier of the cell a to the cell barred list to be T; timing after adding the physical cell identifier of the cell A into the cell forbidden list; and when the time length for adding the physical cell identifier of the cell A into the cell forbidden list reaches T, determining whether the user equipment can carry out communication service in the cell A. For example, the ue may temporarily switch to the cell a from the cell B, perform a test service in the cell a, determine whether the test service can be successfully executed in the cell a according to a service signaling point, and if so, determine that the ue can perform a communication service in the cell a; if not, determining that the user equipment cannot perform the communication service in the cell A, namely that the fault of the user plane of the user equipment is not recovered. Optionally, if the user equipment can perform a communication service in the cell a, the user equipment is handed over from the cell B to the cell a to perform a communication service in the cell a. For example, when the cell B is switched to the cell a, the physical cell identifier of the cell a may be deleted from the cell forbidden list, and cell reselection is started, and when the cell forbidden list is traversed, the physical cell identifier of the cell a is not traversed, so that the cell a is not ignored in the cell reselection process, and thus the cell a is determined to be the cell with the largest reference signal receiving power among the cells in the cell reselection process; switching from the cell B to the cell A in response to the cell A being the cell with the largest reference signal received power among the plurality of cells. Optionally, if it is determined that the user equipment cannot perform the communication service in the cell a, the effective duration for adding the physical cell identifier of the cell a to the cell forbidden list is reset to T.
It can be seen that, in this embodiment, after the physical cell identifier of the cell a is added to the cell forbidden list, the effective duration is set, so that after the user plane failure of the cell a is recovered, the cell a is switched back to perform the communication service in time, thereby implementing the communication service using the cell with the best signal quality, and improving the user experience.

In some possible embodiments, before starting cell reselection, the processing unit 502 is further configured to add a physical cell identifier of the cell a into a cell barring list, where the cell barring list is used to instruct the user equipment to ignore a cell corresponding to each physical cell identifier in the cell barring list when performing cell reselection; in initiating cell reselection and accessing to cell B, the processing unit 502 is specifically configured to:
