The first access point (Access Point, AP for short): the AP that represents the user plane cell of the service; the second AP: the AP that represents the control plane cell of the service, and vice versa.

It should be noted that the foregoing definitions are applicable to the following embodiments of the invention, where different types of cells may correspond to different access points. For example, an access point of a macro cell may be a macro base station, and an access point of a small cell. It may be a micro base station, which is not specifically limited in this embodiment of the present invention.

The technical solutions in the embodiments of the present invention will be described with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. In the following description, for purposes of explanation and description In some embodiments, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description in unnecessary detail. Throughout the description, the same reference numerals and the same names refer to the same or similar elements.

It should be noted that, in order to facilitate the clear description of the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the same items or similar items whose functions and functions are substantially the same are used in the words “first” and “second”. For the sake of distinction, those skilled in the art will understand that the words "first", "second" and the like do not limit the quantity and the order of execution.

As shown in FIG. 1, an embodiment of the present invention provides a method for determining a user plane cell of a service.

S101. The UE acquires performance information of the M cells.

S102. The UE determines performance requirement information of the service.

S103. The UE determines, according to the performance information of the M cells and the performance requirement information of the service, a user plane cell of the service, where the user plane cell is a performance requirement of the M cells that meets the service requirement. At least one cell, M is a positive integer, M ≥ 1.

In the step S101 of the embodiment of the present invention, the performance information of the cell may include at least one of the following information: an air interface return delay, a minimum guaranteed rate that the air interface can provide, or a minimum guaranteed rate level that the air interface can provide. The minimum guaranteed rate or the minimum guaranteed rate level between a certain server, the back delay or one-way delay between the UE and a server, the reliability level that the air interface can provide, the subframe length supported by the cell, and the cell's Load information, whether the cell supports the air interface connection service, whether the cell supports the sparse packet service, the access point name APN supported by the cell, the service item name or service provider supported by the cell, a service item or an access point AP or The end-to-end delay limit, the lowest bit rate upper limit, the highest bit rate upper limit, the lower reliability level, and the tariff provided by a service provider.

It can be understood that the “at least one information” indicates that the performance information of the cell may be one of the information listed above, or may be a combination of any two or more information, for example, the performance information of the cell may include a service. The end-to-end delay limit and the tariff provided by the project, the specific information of the performance information of the cell in the embodiment of the present invention is not specifically limited.

Specifically, the UE may obtain performance information of the M cells in the following manners.

Manner 1: The UE acquires performance information of the M cells notified by the system broadcast.

The system broadcast may carry the frequency information of the neighboring area, and the frequency information may specifically include performance information that can be provided by the cell under each frequency point.

Manner 2: The UE acquires performance information of the M cells notified by the ith AP, where the i th AP is an AP of the i th cell in the M cells, 1 ≤ i ≤ M, i is A positive integer.

The information that the ith AP can notify the UE may be directly the performance information of the M cells, or may be the frequency information of the neighboring cell, and the frequency information may specifically include the performance that the cell can provide under each frequency point. The information in this embodiment of the present invention is not specifically limited.

Exemplarily, as shown in FIG. 2, AP1 broadcasts performance information of M cells, and the UE acquires performance information of M cells broadcast by AP1.

Manner 3: The UE acquires performance information of the cell where the AP is located, which is respectively notified by the APs of the cells of the M cells.

Exemplarily, if M=2, as shown in FIG. 3, AP1 and AP2 respectively broadcast the nature of the cell. The information can be obtained by the UE acquiring the performance information of the local cell broadcasted by the AP1 and the AP2 respectively.

It should be noted that, in the embodiment of the present invention, different types of cells may correspond to different access points, for example, the access point of the macro cell may be a macro base station, and the access point of the small cell may be a micro base station, which is implemented by the present invention. This example does not specifically limit this.

In the step S102 of the embodiment of the present invention, the different services may be corresponding to different performance requirements, and the same service may be corresponding to different performance requirements according to the configuration of the user, which is not specifically limited in this embodiment of the present invention.

Exemplarily, the UE uploads a video to the home or a server through the mobile phone, and can upload the video for the access cell A, the cell B, and the cell C. The rates for uploading the video by the cell A, the cell B, and the cell C are different. The low upload rate is low, and the high upload rate is high. The user can have a configuration on the mobile phone and select the access point with the lowest tariff to upload. At this point, the performance requirements of the service are the lowest.

It should be noted that there is no necessary sequence between step S101 and step S102, and step S101 may be performed first, and then step S102 may be performed; step S102 may be performed first, and then step S101 may be performed; step S102 and step S101 may be simultaneously performed. The embodiment of the present invention does not specifically limit this.

In a possible implementation manner, in step S103, the UE determines the user plane cell of the service according to the performance information of the M cells and the performance requirement information of the service, which may include: Determining, by the performance information of the M cells and the performance requirement information of the service, a cell that meets the performance requirement of the service in the P cells whose signal quality meets a preset threshold in the M cells is a user of the service Face cell, P is a positive integer, P ≥ 1. That is, in this implementation manner, the UE may select a cell that meets the performance requirement of the service from the cells with good signal quality as the user plane cell of the service.

It should be noted that, in this implementation manner, the UE may select a cell with the best performance that meets the performance requirement of the service from the cell with good signal quality as the user plane cell of the service, and may also have good signal quality. All the cells in the cell that meet the performance requirements of the service are determined as the user plane cell of the service, which is not specifically limited in this embodiment of the present invention.

In another possible implementation, the UE determines the user plane cell of the service according to the performance information of the M cells and the performance requirement information of the service, and specifically includes: Determining, according to the performance information of the M cells and the performance requirement information of the service, that the cell quality of the Q cells that meet the performance requirement of the service meets a preset threshold, or the signal quality is the best. The cell is the user plane cell of the service, and Q is a positive integer, and Q≥1. That is, in this implementation manner, the UE may select a cell with good signal quality from a cell that meets the performance requirement of the service as a user plane cell of the service.

It is to be noted that, after acquiring the performance information of the M cells, the UE may determine, according to the performance information of the M cells, the cells that meet the preset performance requirements and have the best signal quality among the M cells. Obtaining a first correspondence between each preset performance requirement and a corresponding cell that meets the preset performance requirement and having the best signal quality; and determining, according to the performance requirement information of the service, and the first correspondence, The user plane cell of the service is not specifically limited in this embodiment of the present invention.

The preset performance requirement may be a requirement of performance information in the performance information, or may be a combination of multiple performance information requirements, such as APN1+ minimum rate (greater than 1000 Mbps), such as service item name + tariff (low/no) The embodiment of the present invention does not specifically limit this. Exemplarily, the first correspondence may be as shown in Table 1.

Table I

Therefore, if the performance requirement information of the service is the lowest rate (more than 1000 Mbps), the user plane cell of the service is determined to be the cell 2 according to the first correspondence.

It should be noted that the measurement period information is given in Table 1, that is, the UE periodically acquires performance information of the M cells. For a frequency band or a frequency point or a cell with low delay performance, the UE performs short cycle measurement, and always obtains a cell whose signal quality meets a preset threshold. For a frequency band or a frequency point or a cell that provides other performance, the UE performs a longer period of measurement to obtain a cell whose signal quality meets a preset threshold. Of course, Table 1 is only a specific example of the first correspondence, and the measurement period information may not be included in the first correspondence, which is not specifically limited in this embodiment of the present invention.

In combination with the above two possible implementation manners, the user plane cell of the service determined by the UE not only has good signal quality, but also facilitates transmission of service data; and the performance is good, and the user is provided with a better service experience.

A method of user plane cell determination of a service will be given below in conjunction with a specific example.

Illustratively, the UE needs to obtain a certain movie service, and the performance requirement is that the minimum guaranteed rate is greater than 200 Mbps. For the access cell A, the cell B, and the cell C, the content can be accessed from a content delivery server (CDN). Service, access cell A and cell B, cell C provide the minimum guaranteed rate that the service can obtain after accessing the cell, or a minimum guaranteed rate level (eg, less than 50 Mbps, 50-200 Mbps, greater than 200 Mbps). Of course, as the number of users increases and the air interface conditions change, the foregoing information may be changed, and the information may be broadcasted in the cell A, and the indications may be broadcasted in the cell A, the cell B, and the cell C, respectively. This is not specifically limited. The UE determines, according to the network indication, a frequency point or a cell that can provide the service, and after performing measurement on the cells, determining that the cell with the best signal quality in the cell with the highest level of the lowest guaranteed rate is the cell B, determining that the cell B is the movie The user plane cell of the service, i.e., accesses the cell B having the highest signal quality with the highest guaranteed rate at the lowest guaranteed rate when the movie service access is to be performed.

Certainly, if the UE determines that the cell with the best signal quality in the cell with the highest guaranteed rate of the lowest guaranteed rate of the service becomes C during the mobile process, the UE determines that the cell C is the user plane cell serving the movie, and the present invention The embodiment does not specifically limit this.

Exemplarily, the user wants to upload a video to the home or a server through the UE (such as a mobile phone), and the user can have a configuration on the UE, and select the access point with the lowest tariff to upload. The video can be uploaded for the access cell A, the cell B, and the cell C. Among them, the charges for uploading the video by the cell A, the cell B, and the cell C are different, and the tariff of the cell B is the lowest. At this time, the cell A, the cell B, and the cell C may indicate, in the broadcast of the local cell or the neighboring cell, the tariff of the UE for the service provided by the local cell or the neighboring cell, and the UE obtains the tariff of the service provided by the different cell, and then provides the service according to different cells. The tariff of the service determines that the cell B with the lowest tariff for providing the service is the user plane cell of the service, that is, uploads through the lowest cost cell B when the video upload is to be performed.

When determining the user plane cell of the service, the UE can determine the user plane cell of the service according to the obtained performance information of the M cells and the performance requirement information of the service, where the user plane cell is the M At least one cell in the cell that meets the performance requirements of the service. Therefore, the method for determining the user plane cell of the service provided by the embodiment of the present invention can provide a user plane cell suitable for the performance requirement of the service when the data of the service is transmitted.

Further, as shown in FIG. 4, in a possible implementation manner, after the UE determines the user plane cell of the service (step S103), the method may further include: S104a and S105a.

S104a. The UE initiates uplink random access at the same time in the control plane cell and the user plane cell.

Optionally, the UE may initiate random access in the user plane cell, and then initiate random access to the control plane cell, which is not specifically limited in this embodiment of the present invention.

S105a. The UE sends the indication information to the second AP, where the indication information is used to indicate a user plane cell of the service of the second AP.

Specifically, in the embodiment of the present invention, after determining the user plane cell of the service, the UE may initiate uplink random access simultaneously in the user plane cell and the control plane cell, and the UE completes uplink random access in the user plane cell to obtain uplink transmission. After the resource is transmitted, the uplink data is sent, and after the uplink of the control plane is completed, the uplink transmission resource is obtained, and then the radio resource control protocol (Radio Resource Control, RRC) connection establishment request message is sent to complete the RRC connection establishment. The UE may be in the RRC connection establishment process or the RRC connection establishment is completed. The user plane cell of the service of the control plane cell is notified, that is, the indication information may be carried by the RRC connection setup request message, or may be carried by the RRC connection setup complete message, which is not specifically limited in this embodiment of the present invention. . Specifically, the method for the UE to determine the control plane cell of the service may refer to the existing solution, and details are not repeatedly described herein.

It should be noted that, in the embodiment of the present invention, the configuration information carried by the user plane of the service and the configuration information carried by the control plane of the service may be configured by default, or may be the user that determines the service by the UE. a plane cell and a control plane cell of the service, and after the user plane cell and the control plane cell simultaneously initiate uplink random access, respectively, after the user plane bearer of the service is established and the control plane bearer of the service is obtained, The embodiment of the invention is not specifically limited thereto. The configuration information carried by the user plane may include: an identifier of the data bearer, a Packet Data Convergence Protocol (PDCP), a Radio Link Control (RLC) layer, and a medium access. The configuration information of the control layer (MAC) layer, and the configuration information carried by the control plane may include: an identifier of the bearer, a configuration information of the RLC layer and the MAC layer, and the like.

Based on the foregoing solution of the embodiment of the present invention, the UE may simultaneously initiate uplink random access in the user plane cell and the control plane cell, and notify the user plane cell of the service of the control plane cell. Therefore, not only the UE can quickly access the user plane cell for transmission of service data, but also enable adjustment of the user plane anchor point in the control plane cell of the service.

That is, different from the establishment method of the user plane bearer in the prior art, in the embodiment of the present invention, the UE first initiates uplink random access in the control plane cell, and after the UE determines the user plane cell of the service, the UE goes to the second AP. After the establishment request message carried by the user plane is sent, after the configuration information carried by the user plane is obtained by the second AP, the user plane bearer of the service is established in the user plane cell.

It should be noted that there is no necessary execution sequence between step S104b and steps S101-S103, and step S104b may be performed first, and then steps S101-S103 may be performed; steps S101-S103 may be performed first, and then step S104b may be performed; Step S104b is performed at the same time as steps S101-S103, which is not specifically limited in the embodiment of the present invention.
