Embodiment 1
[0039] Such as Figure 5 As shown, it is a schematic diagram of the specific processing process applied in the terminal Attach process of the embodiment of the present invention, wherein each STP processing node on the network side (including Figure 5 In the MME, SGW and PDN GW) in the terminal Attach process, specifically perform the following processing:
[0040] S10, the MME sends a create default bearer request message to the SGW;
[0041] S20, the SGW sends a create default bearer request message to the PDN GW;
[0042] S30, after the PDN GW creates a default bearer for the terminal, it will feed back a create default bearer response message to the SGW, wherein the create default bearer response message carries a dedicated bearer creation request message;
[0043] S40, the SGW feeds back the create default bearer response message carrying the create dedicated bearer request message to the MME;
[0044] S50, the MME will simultaneously receive the Create Dedicated Bear...
Embodiment 2
[0049] Such as Figure 6 As shown, it is a schematic diagram of the specific processing process applied in the process of the terminal initiating a PDN connection according to the embodiment of the present invention, wherein each STP processing node on the network side (including Figure 5 The MME, SGW and PDN GW in the terminal) specifically perform the following processing during the terminal initiates the PDN connection process:
[0050] S100, the MME sends a bearer resource establishment command message to the SGW;
[0051] S110, the SGW sends the received bearer resource establishment command message to the PDN GW;
[0052] S120, after the PDN GW agrees to establish a bearer resource for the terminal, it will feed back a bearer establishment request message to the SGW, and the message carries a bearer modification request message;
[0053] S130, the SGW will feed back the bearer establishment request message carrying the bearer modification request message to the MME; ...

Abstract
The invention discloses a method for sending and receiving messages. The method for sending the messages comprises the following steps: embedding a second type GPRS tunneling protocol message into a message body of a first type GPRS tunneling protocol message to be sent; and sending the first type GPRS tunneling protocol message which is embedded with the second type GPRS tunneling protocol message. The method for receiving the messages comprises the following steps: receiving the first type GPRS tunneling protocol message; and analyzing the received first type GPRS tunneling protocol messageto obtain the second type GPRS tunneling protocol message which is embedded in the message body of the first type GPRS tunneling protocol message. Correspondingly, the invention also discloses a device for sending and receiving the messages. The problem that under some communications scenes, different types of messages are sent by using different GTP messages respectively so as to cause adverse effect on a communication process is solved.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a GPRS tunnel protocol message sending and receiving method and a message sending and receiving device thereof. Background technique [0002] In an Evolved Packet System (EPS, Evolved Packet System), a GPRS Tunneling Protocol (GTP, GPRS Tunneling Protocol) message is a tunnel management message that is carried. The existing GTP message is composed of a message header and a message body. The specific format of the GTP message header is as follows: figure 1 As shown, since the message type of the GTP message has been determined in the GTP message header, it is determined that a GTP message can only represent one message type, so that different types of messages can only be sent using different GTP messages, due to communication Problems such as message transmission delays may occur on the network, which may cause different types of GTP messages to arrive at the receiv...
