DETAILED DESCRIPTION OF THE DISCLOSURE

[0136] Embodiments of the present disclosure are further described in detail hereinafter with reference to the accompanying drawings. It should be noted that, in case of no conflict, embodiments of the present disclosure and suitable features in embodiments may be combined with each other.

[0137] Steps shown in flow charts of the accompanying drawings may be executed by a computer system according to a group of computer-executable instructions. In addition, although logical order is shown in the flow charts, in some cases, a different order from herein may be used to execute the shown or described steps.

[0138] It should be noted that, terminologies like “first” and “second” in the specification, claims, and the above-described accompanying drawings of the present disclosure are used for differentiate similar objects, but not used for described specified order or precedence.

[0139] A method for processing information is provided according to an embodiment of the present disclosure, which is performed by a new base station (i.e., a first base station) in a resume procedure across multiple base stations. FIG. 1 is a flow chart illustrating a method for processing information according to an embodiment of the present disclosure. As shown in FIG. 1, a first base station refers to a new base station, and a second base station refers to an old base station. The method provided by the embodiment of the present disclosure includes the following steps, i.e., step 101 to step 103:

[0140] Step 101, by initiating a procedure to a second base station for retrieving user context information, a first base station retrieves the user context information of a UE from the second base station. In some embodiments, the user context information doesn't include user history information.

[0141] In an embodiment of the present disclosure, when the first base station initiates a procedure for retrieving user context information, it may be a long time passed from the time when the second base station suspends the UE, so that the user history information may become inappropriate since it is already outdated. Hence, the second base station decides not to carry the user history information which is already outdated and inappropriate when transmitting the user context information.

[0142] Step 102, by initiating a path switch request message to a device in a core network, the first base station updates bearer path information and resumes the user context information.

[0143] Step 103, the first base station performs one or more of the following operations after the UE resumes to a connected state: re-starting to collect user history information, and re-retrieving user history information from the UE through an air interface.

[0144] In an embodiment of the present disclosure, because in step 101 when the first base station retrieves the user context information, the second base station doesn't transmit the user history information, the first base station in step 103 may not obtain the user history information. Hence, through step 103, relatively new and complete user history information may be obtained, so that the accuracy of the subsequent optimization processing using the user history information may be enhanced.

[0145] Optionally, the method provided by the embodiment of the present disclosure may further include:

[0146] Step 104, when the second base station initiates a suspend procedure for a UE, the second base station reports the user history information to the device in the core network through a request message for suspending the user context information, and a path switch response message, which is received by the first base station from the device in the core network in a path switch request message, includes user history information, thus the first base station uses the received user history information for the subsequent optimization processing after the UE resumes to a connected state. In some embodiments, the received user history information corresponds to a timer. The timer is configured when the device in the core network receives the user history information. Before the timer times out, the device in the core network is allowed to carry the user history information when transmitting a response message to the second base station for resuming the user context information or when transmitting a path switch response message to the first base station.

[0147] It should be noted that, the above-described timer can be appreciated to use for setting validity of the user history information. Within the timing range of the timer, the user history information is regarded to be valid, and the device in the core network sends the user history information to the first base station, so that the first base station performs the subsequent optimization processing based on the validity of the user history information. After the timer times out, the user history information is regarded to be invalid, and the device in the core network doesn't send the user history information, then the step 103 may be performed.

[0148] Optionally, the method provided by the embodiment of the present disclosure may further include:

[0149] Step 105, when the second base station initiates a suspend procedure for a UE, the second base station reports user history information to the device in the core network through a request message for suspending the user context information, and a path switch response message, which is received by the first base station from the device in the core network in a path switch request message, includes user history information and a timestamp, thus after the UE resumes to a connected state, the first base station determines according to the timestamp whether the received user history information is used for the subsequent optimization processing. In some embodiments, the timestamp corresponds to the user history information, and the timestamp is configured when the device in the core network receives the user history information.

[0150] It should be noted that, the above-described timestamp can be appreciated to use for indicating validity of the user history information. After the user history information is received, the first base station may read the corresponding timestamp to determine whether the user history information becomes inappropriate since it is already outdated. For example, if the difference between current time and the timestamp is beyond a threshold, it may be determined that the user history information is inappropriate since it is already outdated. If it is determined that the user history information is not outdated, the first base station may use the received user history information for the subsequent optimization processing. If it is determined that the user history information is already outdated, the step 103 may be performed.

[0151] According to the above-described method provided by an embodiment of the present disclosure, the way of processing user history information in a resume procedure is optimized. The accuracy of the user history information used for the first base station to perform the subsequent optimization processing is enhanced, so that the accuracy of optimization processing is enhanced.

[0152] An embodiment of the present disclosure also provides a method for processing information, which is performed by the above-described base station. In the embodiment, it is a same base station to perform a resume procedure after a suspend procedure. FIG. 2 is a flow chart illustrating another method for processing information according to the embodiment of the present disclosure. The method provided by the embodiment of the present disclosure may include the following steps, i.e., step 201 to step 204:

[0153] Step 201, a base station initiates a procedure for a UE for suspending user context information, and reports user history information to a device in a core network through a request message to the device in the core network for suspending user context information.

[0154] Step 202, the base station updates bearer path information and resumes the user context information through a request message to the device in the core network for resuming the user context information.

[0155] Step 203, the base station receives a response message from the device in the core network for resuming the user context information.

[0156] Step 204, when the response message for resuming the user context information doesn't include the user history information, the base station performs one or more of the following operations after the UE resumes to a connected state: re-starting to collect user history information, and re-retrieving user history information from the UE through an air interface.

[0157] Optionally, the method provided by the embodiment of the present disclosure may further include:

[0158] Step 205, when the response message for resuming the user context information includes the user history information, the base station uses the received user history information for the subsequent optimization processing after the UE resumes to a connected state. In some embodiments, the user history information corresponds to a timer. The timer is configured when the device in the core network receives the user history information. Before the timer times out, the device in the core network is allowed to carry the user history information when transmitting a response message to the base station for resuming the user context information.

[0159] It should be noted that, based on the description of step 205, about the case in step 204 that the response message for resuming the user context information does not include the user history information, it may include two cases: one is, when the device in the core network transmits the response message for resuming the user context information, it is decided not to carry the user history information in the response message for resuming the user context information; the other is, if a timer is configured in step 204 but the timer times out, the user history information is not carried when the device in the core network transmits the response message for resuming the user context information.

[0160] Optionally, the method provided by the embodiment of the present disclosure may further include:

[0161] Step 206, when the response message for resuming the user context information includes the user history information and the timestamp, after the UE resumes to a connected state, the base station determines according to the timestamp whether the received user history information is used for the subsequent optimization processing. In some embodiments, the timestamp corresponds to the user history information, and the timestamp is configured when the device in the core network receives the user history information.

[0162] It should be noted that, the above-described timestamp can be appreciated to use for indicating validity of the user history information. After the user history information is received, the base station may read the corresponding timestamp to determine whether the user history information becomes inappropriate since it is already outdated. For example, if the difference between current time and the timestamp is beyond a threshold, it may be determined that the user history information is inappropriate since it is already outdated. If it is determined that the user history information is not outdated, the first base station may use the received user history information for the subsequent optimization processing. If it is determined that the user history information is already outdated, the step 204 may be performed.

[0163] According to the above-described method provided by an embodiment of the present disclosure, the way of processing user history information in a resume procedure is optimized. The accuracy of the user history information used for the base station to perform the subsequent optimization processing is enhanced, so that the accuracy of optimization processing is enhanced.

[0164] An embodiment of the present disclosure also provides a method for processing information, which is performed by a new base station (i.e., a first base station) in a resume procedure across multiple base stations. FIG. 3 is a flow chart illustrating another method for processing information according to the embodiment of the present disclosure. In the embodiment shown in FIG. 3, a first base station refers to a new base station, and a second base station refers to an old base station. The method provided by the embodiment of the present disclosure includes the following steps, i.e., step 301 to step 303:

[0165] Step 301, by initiating a procedure to a second base station for retrieving user context information, a first base station retrieves the user context information of a UE from the second base station. In some embodiments, the user context information includes user history information and a timestamp. The timestamp is configured by the second base station for the locally stored user context information or user history information after a suspend procedure is completed.

[0166] Step 302, by initiating a path switch request message to a device in a core network, the first base station updates bearer path information and resumes the user context information.

[0167] Step 303, after the UE resumes to a connected state, the first base station determines according to the timestamp whether the user history information is used for subsequent optimization processing.

[0168] It should be noted that, the above-described timestamp can be appreciated to use for indicating validity of the user history information. After the user history information is received, the first base station may read the corresponding timestamp to determine whether the user history information becomes inappropriate since it is already outdated. For example, if the difference between current time and the timestamp is beyond a threshold, it may be determined that the user history information is inappropriate since it is already outdated. If it is determined that the user history information is not outdated, the first base station may use the received user history information for the subsequent optimization processing. If it is determined that the user history information is already outdated, the step 204 may be performed.

[0169] According to the above-described method provided by an embodiment of the present disclosure, the way of processing user history information in a resume procedure is optimized. The accuracy of the user history information used for the first base station to perform the subsequent optimization processing is enhanced, so that the accuracy of optimization processing is enhanced.
