Technical Field

The present application relates to the field of communications, and in particular, to a method, an apparatus, and a terminal for establishing a communication proxy.

Background

In a long term evolution (Long Term Evolution, LTE) system, sidelink (sidelink, or sidelink, etc.) is used for direct data transmission between terminals (UE) without through a network device.

LTE sidelink is suitable for specific public safety transactions (e.g., emergency communication in disaster sites such as fire or earthquake), or internet of vehicles (vehicle to everything, V2X) communication, etc. The internet of vehicles communication includes various services such as basic security type communication, advanced (automatic) driving, formation, sensor expansion, and the like. Since LTE sidelink only supports broadcast communications, it is mainly used for basic security class communications, and other advanced V2X services with strict QoS requirements in terms of latency, reliability, etc. will be supported by NR sidelink.

In a sidelink relay (relay) scenario, a remote (remote) UE and a relay UE are connected through a sidelink link, and the relay UE forwards data between the remote UE and a base station. The relay UE plays a role in data transfer.

In the sip Relay, the remote UE realizes data transmission of the control plane and the data plane through the Relay UE, where the remote UE uses its own identity to communicate with the network side, and the Relay UE only plays a role in data transfer, but in some scenarios, for example, in the personal internet of things, a user has multiple terminals, where a certain terminal may not have its own identity at the network side, so that it cannot communicate with the network side.

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

It should be noted that the techniques described in the embodiments of the present application are not limited to long term evolution (Long Term Evolution, LTE)/LTE evolution (LTE-Advanced, LTE-a) systems, but may also be used in other wireless communication systems, such as code division multiple access (Code Division Multiple Access, CDMA), time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, OFDMA), single-carrier frequency division multiple access (Single-carrier Frequency-Division Multiple Access, SC-FDMA), and other systems. The terms "system" and "network" in embodiments of the application are often used interchangeably, and the techniques described may be used for both the above-mentioned systems and radio technologies, as well as other systems and radio technologies. However, the following description describes a New air interface (NR) system for purposes of example, and NR terminology is used in much of the following description, although these techniques are also applicable to applications other than NR system applications, such as the 6th generation (6th Generation,6G) communication system.

Fig. 1 shows a block diagram of a wireless communication system to which an embodiment of the present application is applicable. The wireless communication system includes a proxy terminal 11, a secondary terminal 12, and a network device 13. The proxy terminal 11 and the auxiliary terminal 12 may also be referred to as a terminal or a User Equipment (UE), and the proxy terminal 11 and the auxiliary terminal 12 may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer), or a terminal-side Device such as a notebook, a personal digital assistant (Personal Digital Assistant, PDA), a palm Computer, a netbook, an ultra mobile personal Computer (ultra-mobile personal Computer, UMPC), a mobile internet Device (Mobile Internet Device, MID), a Wearable Device (or a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), and the Wearable Device includes: a bracelet, earphone, glasses, etc. It should be noted that the specific types of the proxy terminal 11 and the auxiliary terminal 12 are not limited in the embodiment of the present application. The network side device 13 may be a base station or a core network, wherein the base station may be called a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, a transmission and reception point (Transmitting Receiving Point, TRP), or some other suitable terminology in the field, and the base station is not limited to a specific technical vocabulary so long as the same technical effect is achieved, and it should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

In the embodiment of the present application, the auxiliary terminal 12 may be a terminal with a SIM card (i.e. having its own identity on the network side), or a terminal without a SIM card (i.e. having its own identity on the network side). The proxy terminal 11 is a terminal having proxy capability, for example, a terminal with a SIM card. The terminal with proxy capability can also be used as an auxiliary terminal.

The proxy capability refers to the capability of proxy other terminals to establish signaling connection and acquire network configuration. For example, a master terminal or proxy terminal proxies a secondary terminal to initiate a service request to a network (e.g., an access network device), obtains resource configuration information of the network, and forwards the resource configuration information to the secondary terminal. The secondary terminal may then access the network using the identity information of the primary or proxy terminal to thereby transmit the traffic. In the process of transmitting the service by the auxiliary terminal, the main terminal or the proxy terminal keeps the signaling connection with the network.

The method for establishing the communication proxy provided by the embodiment of the application is described in detail below through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Fig. 2 is a flow chart of a method for establishing a communication proxy according to an embodiment of the present application, where the method 200 may be performed by a terminal, and the terminal may be used as a secondary terminal. In other words, the method may be performed by software or hardware installed on the terminal. As shown in fig. 2, the method may include the following steps.

S210, determining the target agent terminal.

In the embodiment of the application, the target proxy terminal is the proxy terminal selected by the auxiliary terminal. In a specific application, there may be a plurality of proxy terminals from which the secondary terminal may select one proxy terminal as the target proxy terminal.

For example, in the personal internet of things, one user has a plurality of terminals, such as a person carrying a plurality of terminal devices or home devices, and the like. At this time, there may be N proxy-capable terminals (N > =1), and the secondary terminal may determine the target proxy terminal from the N proxy terminals.

In a specific application, the terminal with proxy capability may announce that it has proxy capability, i.e. it may be used as a proxy terminal, where the proxy terminal and the auxiliary terminal may be in the same internet of things.

The proxy capability of the proxy terminal refers to the capability of the proxy other terminals to establish signaling connection to acquire network configuration. For example, the target proxy terminal proxies the auxiliary terminal to initiate a service request to the network, acquires the resource configuration of the network, and forwards the resource configuration to the auxiliary terminal. The auxiliary terminal adopts the identity of the target agent terminal to access the network. During the data transmission of the auxiliary terminal, the target proxy terminal maintains the signaling connection with the network.

S212, sending a proxy request message to the target proxy terminal, wherein the proxy request message is used for indicating the auxiliary terminal to communicate with a network side by the identity of the target proxy terminal.

After determining the target proxy terminal, the auxiliary terminal can send a proxy request to the target proxy terminal, and the proxy request is communicated with the network side by the identity of the target proxy terminal.

S214, receiving a proxy request response message, and if the proxy request response message carries proxy confirmation information, establishing a proxy relationship with the target proxy terminal.

After receiving the proxy request message, the target proxy terminal can judge whether the proxy request of the auxiliary terminal can be accepted, and returns a proxy request response message to the auxiliary terminal according to the judging result, the auxiliary terminal receives the proxy request response message, if the proxy request response message carries proxy confirmation information, namely, the target proxy terminal confirms that the proxy request of the auxiliary terminal is accepted, a proxy relation is established with the target proxy terminal, in the subsequent process, the target proxy terminal can proxy the auxiliary terminal to initiate a service request to a network, acquire the resource configuration of the network and forward the resource configuration to the auxiliary terminal, and the auxiliary terminal adopts the identity of the target proxy terminal to access the network. During the data transmission of the auxiliary terminal, the target proxy terminal maintains the signaling connection with the network.

According to the technical scheme provided by the embodiment of the application, after the auxiliary terminal determines the target proxy terminal, the auxiliary terminal sends a request to the target proxy terminal, the request is communicated with the network side by the identity of the target proxy terminal, and after receiving the proxy request response message carrying the proxy confirmation information, the auxiliary terminal establishes a proxy relationship with the target proxy terminal, so that the auxiliary terminal can communicate with the network side by the identity of the target proxy terminal no matter whether the auxiliary terminal has the identity at the network side or not.

In one possible implementation, a terminal group may be established, to which the secondary terminal and the proxy terminal are joining. And a central node is arranged in the terminal group and is used for managing the proxy information of each proxy terminal in the terminal group and managing the proxy requirement of the auxiliary terminal in the terminal group. In this possible implementation, the central node is a shared access module of the terminal group, for example, a proxy database, where the shared access module may be disposed in any terminal in the terminal group, and any terminal in the terminal group may access the central node.

In one possible implementation, the auxiliary terminal may acquire proxy information of each proxy terminal from the central node, and select one proxy terminal as the target terminal according to the proxy information of each proxy terminal. Thus, in this possible implementation, S210 may include:

S2101, receiving proxy information of at least one proxy terminal sent by a central node, wherein the central node is a module for shared access of a terminal group, proxy information of the at least one proxy terminal is stored, and the terminal group comprises the auxiliary terminal and the at least one proxy terminal.

S2103 selects the target proxy terminal from the at least one proxy terminal based on a proxy selection criterion according to the secondary terminal information of the secondary terminal and the proxy information of the at least one proxy terminal.

In the present application, the secondary terminal may select the target proxy terminal at the time of proxy information update of at least one proxy terminal or at the time of secondary terminal information update (e.g., proxy demand update) of the secondary terminal. Alternatively, the secondary terminal may select the target proxy terminal before each service request.

In one possible implementation, the auxiliary terminal receives the proxy information of at least one proxy terminal sent by the central node, which may be sent separately to the auxiliary terminal by the central node. Thus, the S211 may include: and receiving proxy information of the at least one proxy terminal of the auxiliary terminal sent by the central node.

For example, before S2101, the auxiliary terminal joins the terminal group, transmits its auxiliary terminal information to the center node, and after receiving the auxiliary terminal information, the center node transmits proxy information of at least one proxy terminal to the auxiliary terminal. Or after the auxiliary terminal joins the terminal group, when there is a proxy requirement, that is, when the auxiliary terminal needs to be proxied, for example, the auxiliary terminal does not have a SIM card or the auxiliary terminal has limited capability, the auxiliary terminal sends a proxy information acquisition request to the central node, and when the central node receives the proxy information acquisition request, the central node sends proxy information of the at least one proxy terminal to the auxiliary terminal.

Alternatively, the auxiliary terminal receives the proxy information of at least one proxy terminal sent by the central node, and the proxy information may also be broadcast by the central node in the terminal group. Thus, in another possible implementation, S2101 may include: and receiving proxy information of the at least one proxy terminal broadcasted by the central node in the terminal group.

In one possible implementation manner, the proxy information of the at least one proxy terminal may also be sent by the central node after the proxy information of the at least one proxy terminal is updated. For example, after a certain proxy terminal is used as a target proxy terminal of a certain auxiliary terminal and establishes a proxy relationship with the certain auxiliary terminal, a notification is sent to the central node, and after the central node receives the notification, the proxy information of the proxy terminal is updated, or when a new proxy terminal joins the terminal group, the central node also updates the stored proxy information of at least one proxy terminal. Thus, in this possible implementation, S2101 may include: and receiving the proxy information of the at least one proxy terminal sent by the central node, wherein the central node sends the proxy information of the at least one proxy terminal after the proxy information of the at least one proxy terminal is updated. The central node may send to each auxiliary terminal in a unicast manner, or may broadcast in the terminal group in a broadcast manner.

In another possible implementation manner, the central node may also select a target proxy terminal for the auxiliary terminal, and send proxy information of the target proxy terminal to the auxiliary terminal. Thus, in this possible implementation, S210 may include: s2102, receiving proxy information of the target proxy terminal sent by a central node.

In the above possible implementation manner, the central node may select the target proxy terminal for the auxiliary terminal according to the proxy information of the proxy terminal stored in the central node. That is, the target proxy terminal is a proxy terminal selected from the at least one proxy terminal based on proxy selection criteria for the center node according to the auxiliary terminal information of the auxiliary terminal and the proxy information of the at least one proxy terminal.

In the above possible implementation manner, the central node may send a target proxy terminal acquisition request to the central node after receiving the auxiliary terminal information of the auxiliary terminal or when the auxiliary terminal has a proxy requirement, and the central node sends proxy information of the target proxy terminal to the auxiliary terminal when receiving the request. Alternatively, the central node may be selected from the at least one proxy terminal for the secondary terminal after the secondary terminal information of the secondary terminal is updated or after the proxy information of the at least one proxy terminal is updated. Thus, in one possible implementation, S2102 may include: and receiving the proxy information of the target proxy terminal selected and sent by the central node, wherein the target proxy terminal is selected from the at least one proxy terminal by the central node after the auxiliary terminal information of the auxiliary terminal is updated, or the central node is selected from the at least one proxy terminal after the proxy information of the at least one proxy terminal is updated.

In another possible implementation manner, the proxy information of the proxy terminals may also be managed in a distributed manner, that is, without setting a central node, each proxy terminal in the at least one proxy terminal sends its proxy information, and the auxiliary terminal obtains the proxy information of the at least one proxy terminal. Thus, in this possible implementation, S210 may include:

s2104 receives proxy information of at least one proxy terminal transmitted by the at least one proxy terminal.

S2106 selects the target proxy terminal from the at least one proxy terminal based on a proxy selection criterion according to the secondary terminal information of the secondary terminal and the proxy information of the at least one proxy terminal.

In one possible implementation, at least one proxy terminal may broadcast its proxy information within the terminal group in S2104, e.g., when a proxy information of a proxy terminal is updated, the proxy terminal broadcasts updated proxy information within the terminal group, or when a proxy terminal joins the terminal group as a new proxy terminal. Alternatively, when a certain auxiliary terminal joins the terminal group, each proxy terminal in at least one proxy terminal unicasts its proxy capability to the auxiliary terminal. Thus, in this possible implementation, S2104 may include: and receiving proxy information of the at least one proxy terminal broadcasted by the at least one proxy terminal in a terminal group, wherein the terminal group comprises the auxiliary terminal and the at least one proxy terminal.

In each of the foregoing possible implementations, optionally, the auxiliary terminal information may include at least one of: the type of the auxiliary terminal; the auxiliary terminal requests the service type of the proxy; identification information of the auxiliary terminal; the proxy requirements of the secondary terminal, e.g., an indication that the secondary terminal needs to be proxied, a reason for needing to be proxied (e.g., the secondary terminal has no SIM card, or has limited capabilities, etc.).

In each of the possible implementations described above, the agent selection criteria may include at least one of:

(1) Selecting according to the proxy priority of the at least one proxy terminal; in a specific application, the plurality of proxy terminals may set the same or different levels of priority. The high priority proxy terminal tends to be selected as the target proxy terminal. The priority may be set by the user according to factors such as terminal capability, terminal service, and terminal tariff.

(2) Selecting according to the availability status of the at least one proxy terminal; that is, according to whether at least one proxy terminal can normally provide the proxy service, a proxy terminal capable of normally providing the proxy service is selected as a target proxy terminal, and proxy terminals having abnormal proxy states, such as a shutdown state, a non-service area state, a proxy overload state, and the like, are excluded.

(3) And selecting according to the reliability state of the at least one proxy terminal. That is, reliability status information of at least one proxy terminal is compared, and a proxy terminal in a better state, for example, a proxy terminal with higher signal strength, higher power, or the like, is selected as a target proxy terminal.

It should be noted that the above agent selection criteria may be used alternatively or in combination. For example, if there are a plurality of agent terminals of the same priority among the plurality of agent terminals, an agent terminal of a normal agent state may be selected therefrom. If a plurality of proxy terminals with the same priority and in a normal proxy state exist, reliability state information of the plurality of proxy terminals is further compared, and the proxy terminal in a better state is selected as a target proxy terminal.

In another possible implementation, a certain proxy terminal may be directly used as the target proxy terminal, for example, the user sets a certain proxy terminal as the target proxy terminal, or the user sets the priority of a certain proxy terminal to be the highest, and then the proxy terminal may be used as the target proxy terminal to send proxy information thereof to the auxiliary terminal. Thus, in this possible implementation, S210 may include: and S2105, receiving proxy information sent by the target proxy terminal, wherein the proxy information indicates that the target proxy terminal is the current main terminal.

In the above possible implementation manner, the target proxy terminal may send its proxy information when its related information is modified, for example, when a certain proxy terminal is modified to be the target proxy terminal (may also be referred to as a master terminal) or its priority is modified, it sends the proxy information as the target proxy terminal to the slave terminal. Or, the target proxy terminal may also send the proxy information to the auxiliary terminal when a new auxiliary terminal joins the terminal group or the auxiliary terminal information of the auxiliary terminal is updated.

In the possible implementation manner, the proxy information received by the auxiliary terminal may be unicast to the auxiliary terminal by the target proxy terminal, or may be broadcast by the target proxy terminal in the terminal group. Thus, S2105 may include: and receiving proxy information of the target proxy terminal broadcasted in a terminal group by the target proxy terminal, wherein the terminal group comprises the auxiliary terminal and the target proxy terminal.

In each of the above possible implementations, the proxy information of the proxy terminal includes, but is not limited to, at least one of:

1. identification information of the proxy terminal; the identification information may be identification information of the proxy terminal in the terminal group, or may be identification information of the proxy terminal in the communication network, which is not limited in this embodiment.

2. Proxy capability information of the proxy terminal; wherein the agent capability information may include at least one of: (1) Support the business type of the agency, such as Voice Call business, data Service (Data Service); (2) QoS type; (3) Slicing (slicking); (4) Multiple radio-dual connectivity (Multi-Radio Dual Connectivity, MR-DC) capabilities, such as EN-DC, NR-DC, etc.

3. Proxy priority information of the proxy terminal; specifically, the user can set the service according to the capacity of the proxy terminal, the service type of the proxy terminal, the tariff of the proxy terminal and other factors.

4. Proxy state information of the proxy terminal.

The proxy state information of the proxy terminal may include:

availability status, i.e. whether the proxy terminal is able to normally provide proxy services, e.g. network coverage status, e.g. not in service area, etc.; state of charge, such as low charge, etc.; a terminal on-off state; the proxy load state, such as the number of auxiliary terminals for which a proxy relationship has been established, i.e., the number of auxiliary terminals for which a proxy relationship has been established without ongoing traffic, and/or the number of auxiliary terminals being proxied, i.e., the number of auxiliary terminals for which a proxy terminal task is being performed; and

Reliability status. Including but not limited to at least one of: signal strength status, such as cell signal strength indication, etc.; a moving speed such as a high-speed movement, a stationary state, etc.; radio Resource Control (RRC) state: idle, inactive, connected, etc.; non Access Stratum (NAS) state: such as cm_idle, cm_connected, etc.

In each possible implementation manner, the proxy request message may carry service request information, where the service request information is used to indicate that the auxiliary terminal requests the proxy service. I.e. the proxy request message may indicate the service of the requesting proxy, so that the target proxy terminal may determine whether to proxy the service of the auxiliary terminal according to the service.

According to the technical scheme provided by the embodiment of the application, for the personal internet of things (IOT), the auxiliary terminal can flexibly select the proxy terminal under a user multi-terminal scene, so that the convenience and the efficiency of the personal IOT are improved.

Fig. 3 is another flow chart of a method for establishing a communication proxy according to an embodiment of the present application, where the method 300 may be performed by a terminal. The terminal may act as a proxy terminal in fig. 1. In other words, the method may be performed by software or hardware installed on the terminal. As shown in fig. 3, the method may include the following steps.

And S310, receiving a proxy request message sent by an auxiliary terminal, wherein the proxy request message is used for requesting the proxy terminal to communicate with a network side by the identity of the proxy terminal.

The proxy request message is the same as the proxy request message in the method 200, and specific reference may be made to the description related to the method 200.

And S312, if the proxy request of the auxiliary terminal is determined to be accepted, a proxy request response message is sent to the auxiliary terminal, and a proxy relation is established with the auxiliary terminal, wherein the proxy request response message carries proxy confirmation information.

If the proxy terminal determines that the proxy request of the auxiliary terminal can be accepted, the proxy request response message carries proxy confirmation information and establishes a proxy relationship with the auxiliary terminal; if the proxy terminal determines that the proxy request of the auxiliary terminal is not accepted, the proxy request response message can carry non-acknowledgement information, the proxy request of the auxiliary terminal is refused, and the auxiliary terminal can reselect the target proxy terminal after receiving the proxy request response message.

By the technical scheme provided by the embodiment of the application, the proxy terminal receives the proxy request of the auxiliary terminal, and if the proxy request is confirmed to be accepted, the proxy relationship is established with the auxiliary terminal, so that the identity of the proxy terminal can be used for proxy communication between the auxiliary terminal and the network side, and the auxiliary terminal can realize communication with the network side by the identity of the proxy terminal no matter whether the auxiliary terminal has the identity on the network side or not.

In one possible implementation, if the proxy terminal supports the dual connectivity (Dual Connectivity, DC) function, after the proxy relationship is established with the secondary terminal, the dual connectivity may be established with the network side, carrying data transmission between the secondary terminal and the network side through one of the connections.

In one possible implementation, before S310, the proxy terminal may transmit its proxy information so that the secondary terminal may determine that the proxy terminal has proxy capabilities, thereby selecting the proxy terminal to proxy. Thus, in this possible implementation, before S310, the method may further include: s301, sending the proxy information of the proxy terminal.

The proxy information of the proxy terminal may be centralized as described in the above method 200, or may be distributed. Thus, in one possible implementation, S301 may include: and sending the proxy information of the proxy terminal to a central node. I.e. the central node maintains the proxy information of the proxy terminal in a unified way.

In the possible implementation manner, the central node may also maintain auxiliary terminal information of the auxiliary terminal. For example, the auxiliary terminal requests to join the terminal group, sends its auxiliary terminal information to the central node, and the central node notifies the target proxy terminal (i.e. the main terminal) or the trusted proxy terminal of the terminal group, and if the target proxy terminal or the trusted proxy terminal confirms permission, the central node is updated to store the auxiliary terminal information of the auxiliary terminal. Optionally, the target proxy terminal or the trusted proxy terminal may also send a success response message or a failure response message to the auxiliary terminal, indicating whether the auxiliary terminal successfully joins the terminal group.

In yet another possible implementation, S301 may include: and broadcasting the proxy information of the proxy terminal in a terminal group, wherein the terminal group comprises the auxiliary terminal and the proxy terminal. I.e. proxy information of the distributed management proxy terminal.

In the implementation manner of proxy information of the distributed management proxy terminal, optionally, when the auxiliary terminal requests to join the terminal group, the auxiliary terminal information may be sent to a target proxy terminal (i.e. a main terminal) or a trusted proxy terminal, and if the target proxy terminal or the trusted proxy terminal confirms permission, the auxiliary terminal is allowed to join. Optionally, the target proxy terminal or the trusted proxy terminal may also send a success response message or a failure response message to the auxiliary terminal, indicating whether the auxiliary terminal successfully joins the terminal group.

In the present application, as described in the method 200, the proxy information of the proxy terminal may include a plurality of items, for example, at least one of the following: identification information of the proxy terminal; proxy Capability information (Proxy Capability) of the Proxy terminal; proxy Priority information (Proxy Priority) of the Proxy terminal; proxy State information (Proxy State) of the Proxy terminal. Therefore, in S301, the proxy terminal may send each item of proxy information, i.e. send a plurality of messages, or may send all the proxy information together, i.e. send one message, which is not limited in this embodiment.

As described in the above method 200, the proxy terminal may also directly send its proxy information as the target proxy terminal, so in another possible implementation, S301 may include: and broadcasting the proxy information of the proxy terminal in a terminal group, wherein the proxy information indicates that the proxy terminal is a target proxy terminal, and the terminal group comprises the auxiliary terminal and the proxy terminal.

In the possible implementation manner, the proxy terminal may send at least one of the following proxy information to the auxiliary terminal through one or more messages: identification information of the proxy terminal; proxy Capability information (Proxy Capability) of the Proxy terminal; proxy Priority information (Proxy Priority) of the Proxy terminal; proxy State information (Proxy State) of the Proxy terminal, and notifies the secondary terminal that the Proxy terminal is a target Proxy terminal.

In each of the above possible implementations, the proxy terminal may send its proxy information when joining the terminal group, or the proxy terminal may send the proxy information after the proxy information is updated. Thus, in one possible implementation, the method may further comprise: and if the proxy information of the proxy terminal is updated, transmitting the updated proxy information of the proxy terminal. By the possible implementation manner, the proxy terminal can timely inform the central node or the auxiliary terminal when the proxy information of the proxy terminal is updated.

In one possible implementation manner, after receiving the proxy request message sent by the auxiliary terminal, the proxy terminal may determine to accept the proxy request of the auxiliary terminal when determining whether to accept the proxy request, where at least one of the following cases is adopted:

(1) The auxiliary terminal and the proxy terminal are positioned in the same terminal group; i.e. the secondary terminal is a trusted terminal.

(2) The proxy terminal has the capability of proxy the auxiliary terminal to request the proxy service, wherein the proxy request message carries service request information indicating the proxy service.

(3) The current proxy state of the proxy terminal allows proxy of the secondary terminal.
