Detailed Description
The present application was made based on the recognition and study of the following problems by the inventors:
generally, in the processes of power-on, offline, reestablishment, and the like, a user terminal needs to determine whether to camp in a current cell by judging whether a cell camping condition is satisfied. After receiving a system information block (which may include a first system information block, a second system information block, and other information blocks) sent by a network side, the user terminal does not check whether the system information block has timer and constant information, and thus when other conditions are met, the user terminal considers that the cell is suitable for camping, and subsequently initiates a service, such as making a call, browsing a web page, or video, in the cell. When a user terminal makes a call, browses a webpage or a video, and the like, if the position information of the user terminal is weak, the user terminal initiates a rebuilding process, and in the rebuilding process, the values of timers such as T310, N310, T311, N311, and the like are needed.
Note that, according to the 3rd Generation Partnership Project (3 GPP) protocol, the values of the timers such as T310, N310, T311, N311, etc. are obtained from a Radio Resource Control reset (rrcReconfiguration) message and a first system information block. For example, the value of the timer in the radio resource control reset message is used if the value of these timers is provided in the radio resource control reset message, otherwise, the value of the timer provided by the first system information is used. The rrc reset message is sent to the ue through the network, and is used to modify a network connection parameter, where a timer and a constant (rlf-timer and connections, radio Link Failure) in a Special Cell configuration (spcellconfiguration) in a master Cell group (masterCellGroup) in a non-critical extension (nonCriticalExtension) in the rrc reset message include values of timers such as T310, N310, T311, and N311.
However, the timer and the constant information in the first system information module are optionally configured, so when the rrc reset message and the first system information module do not provide the values of the timers, such as T310, N310, T311, and N311, the user terminal may not detect the radio link for a long time due to failing to obtain the values of the timers, and finally, a phenomenon of network disconnection or other phenomena that a network service cannot be provided may occur, which affects user experience. Based on this, the present application provides a cell residence method, by setting a first cell that does not carry timer and constant information as prohibited access, it is able to effectively avoid the problem that a user terminal encounters offline or other network services cannot be provided when performing a reestablishment process on the first cell, and meanwhile, when a plurality of first cells are prohibited access, trying to reside in the first cell, it is able to ensure that a user can obtain basic network services, and user experience is improved.
Fig. 1 is a flowchart illustrating a cell camping method according to an embodiment of the present invention.
As shown in fig. 1, the cell camping method may include the following steps:
s1, receiving a system information block of a first cell sent by a network side.
Specifically, when the user terminal performs cell search and residence, the user terminal receives a system information block of the first cell sent by the network side, where the system information block includes cell selection related information, cell access related information, and the like.
And S2, setting the first cell as the forbidden access based on the fact that the system information block of the first cell does not carry timer and constant information.
That is, when the system information block of a cell does not contain the timer and the constant information, the cell is directly set as the forbidden access. Specifically, a cell which does not include the timer and the constant information is added to the forbidden access cell list, that is, the cell is set as the forbidden access, so that the problem that the user terminal is disconnected or cannot provide network service when the user terminal performs a reestablishment process on the current cell can be avoided.
In this embodiment, after the first cell is set as the prohibited access, the mobile terminal further continues to find a network to determine the first plurality of cells.
Further, the mobile terminal network finding comprises: the mobile terminal receives a message from the second cell; the second cell is added to the first plurality of cells based on determining the second cell to be a detectable cell. Specifically, after the first cell is set as the forbidden access, the ue searches for information of other surrounding cells, that is, cells that are not forbidden to be accessed by the ue and that can be detected, and adds the cells to the first plurality of cells to find cells where the ue can camp.
And S3, trying to reside the first cell when the first plurality of cells are determined to be access forbidden.
That is, when all detectable cells searched by the ue are in the prohibited access list, that is, none of the cells can camp, the first cell is attempted to camp, so as to avoid the situation that the ue is out of service, and ensure that the ue can obtain basic network service.
In this embodiment, the first cell not carrying the timer and the constant information is set as the prohibited access, so that the problem that the user terminal encounters offline or other problems that the network service cannot be provided when the user terminal performs the reestablishment process on the cell can be avoided.
In some embodiments, attempting to camp on the first cell comprises: and when the first cell meets the first preset resident condition, determining that the first cell can reside.
Specifically, when determining that the first plurality of cells are all prohibited from accessing, the first cell is removed from the prohibited access cell list, and when the first cell meets a first preset residence condition, it is determined that the first cell can reside, and then the first cell is attempted to reside, so as to avoid the phenomenon that the user terminal is offline or otherwise unable to provide network service when the user terminal directly performs a reestablishment process on the first cell, and simultaneously ensure that the user can obtain basic network service, thereby improving user experience.
Optionally, in some embodiments, the first preset dwell condition includes: (1) A Public Land Mobile Network (PLMN) of the first cell is a selectable PLMN (i.e., selected PLMN) provided by a Non-Access Stratum (NAS), or is a registered PLMN (i.e., RPLMN that was last camped on), or is one of an Equivalent PLMN list (i.e., equivalent PLMN list); (2) The Reference Signal Receiving Power (RSRP) and the Reference Signal Receiving Quality (RSRQ) of the first cell satisfy the S criterion requirement; (3) The Tracking area code of the first cell is not in a Roaming Forbidden access cell list (Forbidden access Areas for Roaming list) provided by a non-access stratum; (4) The first cell is not in the list of barred access cells, i.e. the cell is not barred access.
Further, the first cell is determined to be in the forbidden access cell list based on any one of the following conditions being satisfied:
(1) The mobile terminal cannot receive a Master Information Block (MIB) transmitted by the network side. It should be noted that the primary message block is sent to the ue by the network side, and the ue needs to receive the primary message block first when performing cell search and residence.
(2) The mobile terminal receives a primary message block indicating that a forbidden access identifier (cellBarred) is 1.
(3) The mobile terminal cannot receive the first system information block sent by the network side. It should be noted that the first system information block is sent to the user terminal by the network side, and the user terminal also needs to receive the first system information block after receiving the primary message block when performing cell search residence.
(4) The first system information block received by the mobile terminal does not carry a tracking area code (trackingAreaCode). It should be noted that the tracking area code is located in PLMN identity list information (PLMN-identity info) in a PLMN identity list (PLMN-identity list) in cell access related information (cellaccessratedinfo) in a first system information block sent by the network side, and is used to indicate a tracking area code value of the cell.
(5) The network supports a frequency offset of 7.5khz (frequenchShift 7p5 khz), but the mobile terminal does not. It should be noted that the frequency offset of 7.5khz is in the frequency band bandwidth class frequency band configuration (frequencyinful) in the uplink configuration common (uplinkconfiguncommon) cell in the common information (serving cell configcommon) of the serving cell of the first system information block, and is used for indicating whether the frequency offset of 7.5khz is supported.
(6) The first system information block does not carry timer and constant information.
In some embodiments, the cell camping method further comprises: based on determining that the first cell can camp on, the mobile terminal acquires a mobile communication service through the first cell.
Specifically, when a system information block of a first cell does not carry timer and constant information and a plurality of first cells are all prohibited to access, trying to camp on the first cell, and when trying to camp on and the first cell meets a first preset camping condition, determining that the first cell can camp on, and at the moment, obtaining mobile communication service by the mobile terminal through the first cell; or, when the system information of the first cell carries the timer and the constant information and the first cell meets the residence condition, determining that the first cell can reside, and at this time, the mobile terminal obtains the mobile communication service through the first cell. Therefore, the phenomenon that the user terminal is disconnected or cannot provide network service when the user terminal conducts the reestablishment process on the cell which does not carry the timer and the constant information can be avoided, meanwhile, the user can be ensured to obtain the basic network service, and the user experience is improved.
To make the present application more clear to those skilled in the art, as a specific example, referring to fig. 2, a cell camping method may include the following steps:
step S10, the user terminal receives the system information block of the first cell sent by the network side.
Step S11, the user terminal judges whether the system information block of the first cell provides the timer and the constant information. If yes, executing step S12; otherwise, step S13 is executed.
Step S12, the user terminal judges whether the first cell meets the resident condition. If yes, step S18 is performed, otherwise step 14 is performed.
Step S13, the user terminal sets the first cell as the forbidden access.
Step S14, the user terminal searches for the network, that is, the user terminal searches for the detectable cell and adds the detectable cell into the first plurality of cells.
And step S15, judging whether the first plurality of cells are all access forbidden. If so, step S16 is performed, otherwise, step S17 is performed.
And step S16, trying to reside in the first cell. That is, when the first cell satisfies the first preset camping condition (specifically, as described above, it is not described herein again), it is determined that the first cell can camp on, and the ue obtains the mobile communication service through the first cell.
And S17, judging whether the cells which are not forbidden to be accessed in the first plurality of cells meet the residence condition. If yes, step S18 is executed, otherwise, step S16 is returned to.
It should be noted that the cell that is not barred from accessing, that is, the cell is not in the barred access cell list.
Step S18, determining that the cell can reside, and the user terminal obtaining the mobile communication service through the cell.
In this embodiment, when the user terminal receives the system information block of the cell, it finds that the current cell does not carry timer and constant information, the user terminal does not reside in the cell, sets the cell as the cell prohibited from being accessed, and then adds the cell into the cell prohibited from being accessed list, so as to avoid unpredictable problems such as network disconnection and the like when a subsequent reconstruction process is performed on the cell; meanwhile, after trying that all cells can not reside, removing the cell which does not carry the timer and the constant information from the forbidden access list and trying to reside in the cell, thereby ensuring that the user terminal obtains basic network service. In short, in the embodiment, the cells which do not carry the timer and the constant information do not reside first, and the residence is attempted only when all the cells do not meet the residence condition, so that unpredictable phenomena such as network disconnection and the like occurring when the user terminal performs the reestablishment process on the current cell are avoided, and the user can be ensured to obtain basic network service.
In summary, according to the cell camping method of the embodiment of the present invention, the first cell is set as the prohibited access according to the received first system information block of the first cell sent by the network side, and when traversing all detectable cells and determining that all cells are prohibited from accessing, the cell that does not carry the timer and the constant information is attempted to camp, so as to avoid the phenomenon of offline or other incapability of providing network service when the user terminal performs the reestablishment process on the current cell, ensure that the user can obtain the basic network service, and improve the user experience.
