S102, judging whether the terminal initiates a second channel connection establishment request, if the terminal initiates the second channel connection establishment request, storing the paging request and establishing the second channel connection with the terminal.
When the terminal is trying to establish a connection of a second channel different from the first channel, because of a concurrency conflict, a paging request cannot be sent to the terminal through the first channel, and therefore the paging request needs to be temporarily stored and a second channel connection needs to be established with the terminal according to the request of the terminal.
S103, sending a paging request to the terminal through a second channel.
In the method for sending the paging request, when the paging request sent through the first channel and the second channel connection establishment request are in concurrent conflict, the paging request is stored, the second channel connection is established, and the paging request is sent on the channel, namely the second channel connection is established and the paging request is sent to the terminal, so that the problem that the terminal cannot receive the paging request due to the paging conflict is solved.
Example 2:
as shown in fig. 2, the present embodiment provides a method for sending a paging request, where the paging request can be sent through at least a first channel and a second channel.
Optionally, the first channel is a connection channel established by using a Circuit Switched Fallback (CSFB) technique.
CSFB is a common method in 4G telephone communications.
Optionally, the second channel is a connection channel established by using a Radio Resource Control (RRC) technology.
RRC plays an important role in the same communication and information interaction of a terminal and a network.
The specific method comprises the following steps:
s200, optionally, before receiving the information of the paging request through the first channel, the method further includes: and starting the first channel to enable the first channel to be in a state of receiving and sending the information of the paging request and sending the paging request.
Before receiving the information for sending the paging request, the calling terminal initiates a first tunnel (e.g., CSFB) to be in a state capable of receiving the information for sending the paging request, so that the information for sending the paging request can be sent through the first tunnel.
After the calling terminal is powered on, the calling terminal starts a joint attachment flow, the joint attachment flow is a first step of a CSFB flow and aims at enabling the CSFB to be in a usable state, and the joint attachment flow specifically comprises the following steps:
s2001, after the calling terminal is powered on, sending an attach request to the MME, where an attach request message carries an indication of supporting the CSFB capability.
S2002, after receiving the attach request, the MME derives VLR (Visitor Location Register) information of the CS (Circuit Switched) domain while performing the attach, and initiates a Location update request to the VLR.
S2003, VLR stores the information sent by MME, creates SGs association with MME, and meanwhile VLR initiates a location updating process to HLR and returns confirmation information to MME according to terminal information and location area information.
S2004, the MME sends the information distributed to the calling terminal by the VLR to the calling terminal by including the information in the attachment request receiving message.
And completing the joint attachment process of the calling terminal through the steps S2001-S2004. The combined attach procedure is initiated and completed after power-on, in preparation for the call service of the terminal. When the calling terminal needs to call a called terminal, the following procedure is continued.
S201, receiving information for sending the paging request through the first channel, wherein the information for sending the paging request comprises the step of sending the paging request to the terminal through the first channel.
When a paging request needs to be sent, for example, a calling terminal needs to establish a call connection with a called terminal, a communication network (e.g., eNB) receives information for sending the paging request, where the information for sending the paging request includes a paging request sent by the calling terminal and a channel used for sending the paging request.
Optionally, the terminal is a mobile terminal equipped with a multi-mode card.
The terminal comprises a calling terminal and a called terminal.
The terminal equipped with the multi-mode card can send information in various ways, such as establishing a call connection through a CSFB or establishing a call connection by using an RRC.
Receiving the information of the paging request through the CSFB specifically includes the following steps:
and S2011, when the calling terminal has a paging request to be sent, the calling session control equipment of the calling terminal sends a query request to the HLR according to the called number, and the HLR feeds back the MSC position information.
S2012, the calling session control device of the calling terminal sends a call request to the MSC, and the MSC sends a paging request to the MME according to the SGs interface information.
S2013, the MME sends a paging request to the eNB.
Through steps S2011, S2012, and S2013, the eNB receives the information of sending the paging request sent by the calling terminal, and will send the paging request to the called terminal.
S202, judging whether the terminal initiates a second channel connection establishment request, if the terminal initiates the second channel connection establishment request, saving the paging request and establishing the second channel connection with the terminal.
A communication network, such as an eNB, determines whether a terminal of a call is initiating a second channel (RRC) connection establishment request. If the called terminal is initiating the second channel (e.g. RRC) connection establishment request, the paging request to the called terminal is saved, and the second channel connection (e.g. RRC) is established with the called terminal.
Optionally, the paging request is saved using the eNB.
If the eNB receives the paging request sent by the MME and the called terminal initiates RRC connection establishment with the eNB at the moment, the eNB stores the paging request message and establishes RRC connection with the called terminal.
The method specifically comprises the following steps:
s2021, the eNB finds that the called terminal initiates an RRC connection establishment request, and stores the paging request.
S2022, the eNB establishes RRC connection with the called terminal.
The communication eNB establishes RRC connection with the called terminal through steps S2021 and S2022 and stores the paging request that should be originally transmitted through the CSFB.
S203, sending a paging request to the terminal through a second channel.
The method comprises the following steps that the eNB establishes RRC connection with a called terminal, the eNB sends a paging request to the called terminal on the RRC, and after the paging request is sent, the called terminal and a communication network complete call establishment with a calling terminal through information transmission, and the method comprises the following specific steps:
s2031, the eNB sends a paging request to the called mobile on RRC.
S2032, the called terminal sends the expanding business request to MME after receiving the paging request, and the MME sends information to eNB after receiving the request.
S2033, the eNB sends the configured fallback cell identifier and the configured frequency point to the called terminal according to the cell information where the mobile terminal is currently located.
S2034, the called terminal falls back to the cell, sends out the service establishment request, and establishes the communication with the calling terminal.
The steps from S2031 to S2034 are used for sending a paging request on RRC, and finally, the call between the calling terminal and the called terminal is established.
In the method for sending the paging request, when the paging request sent through the circuit domain fallback channel and the radio resource control connection establishment request are in concurrent conflict, the paging request is stored, the radio resource control connection channel is established, and the paging request is sent on the channel, namely the radio resource control connection channel is established and the paging request is sent to the terminal, so that the problem that the terminal cannot receive the paging request due to paging conflict is solved.
